Hinges have been used since ancient times, with evidence of their use dating back to 1600 BCE in Egypt. They have evolved over time and are now manufactured using advanced techniques and materials. This component play a crucial role in doors, windows, cabinets, and many other types of furniture. They allow for smooth movement, stability, and security of these structures. 

Hinges come in a variety of shapes, sizes, and materials, each with its own unique characteristics, and the manufacturing process of hinges involves several stages, including cutting and shaping, heat treatment, surface finishing, and assembly.

What are the different types of hinges?

Hinges can be classified into several types, including butt hinges, continuous hinges, piano hinges, concealed hinges, and strap hinges. Butt hinges are the most common type and are used in doors and cabinets. Continuous hinges, also known as piano hinges, are long and narrow and are used in applications such as piano lids and small doors. Concealed hinges are invisible when the door or cabinet is closed, giving them a sleek appearance. Strap hinges are used in heavy-duty applications such as gates and barn doors.

The manufacturing process of hinges can differ based on the type of hinge being produced. For example, concealed hinges require more precise machining and assembly, while butt hinges are simpler to manufacture.

Which Materials Used in Hinges?

Hinges can be made from many materials, including steel, stainless steel, brass, bronze, and aluminum. The choice of material depends on the application and the desired strength and durability of the hinge. Steel is the most commonly used material for hinges due to its strength and affordability. Stainless steel is often used in applications where corrosion resistance is required, such as in marine environments. Brass and bronze are popular choices for decorative hinges due to their aesthetic appeal, while aluminum is used in lightweight applications.

To ensure the quality of the hinges, raw materials are carefully selected and undergo quality control procedures. This includes testing the material for strength, durability, and corrosion resistance.

The Production Process of Hinges

This is done using a variety of cutting and shaping techniques, including stamping, forging, and machining. Stamping is often used for the mass production of simple hinges while forging and machining are used for more complex designs.

2-Heat treatment

After the raw material has been cut and shaped, it undergoes a heat treatment process to increase its strength and durability. This involves heating the material to a specific temperature and then cooling it at a controlled rate. The heat treatment process can significantly improve the mechanical properties of the material, making it more resistant to wear and deformation.

3-Surface finishing

Once the material has been heat-treated, it undergoes a surface finishing process to improve its appearance and protect it from corrosion. This can include polishing, plating, or powder coating. Polishing is often used for brass and bronze hinges, while plating is used for steel and stainless steel hinges.

4-Assembly

The final stage of the production process involves assembling the different components of the hinge. This can involve welding, riveting, or screwing the parts together. The assembly process requires precision and attention to detail to ensure that the hinge operates smoothly and reliably.

Quality Control of Hinges

To ensure the quality and reliability of the hinges, quality control procedures are implemented throughout the production process.

• Inspection and testing during production: During the production process, hinges are inspected and tested at various stages to ensure that they meet the required standards. This can include visual inspections, dimensional measurements, and material testing. Visual inspections are done to check for any defects or inconsistencies in the material or finish. Dimensional measurements ensure that the hinge meets the required specifications and tolerances. Material testing is done to check the strength, hardness, and corrosion resistance of the hinge material.
• Final inspection and testing: After the hinges have been assembled, they undergo a final inspection and testing process to ensure that they meet the required standards. This can include functional testing, where the hinge is tested for its smooth operation and load-bearing capacity. Durability testing is done to check how well the hinge can withstand repeated use and exposure to different environmental conditions. Corrosion resistance testing is done to check how well the hinge resists corrosion in different environments.

Spring hinges are special hinges that are installed on spring doors or cabinet doors to automatically close the door after it is opened. They are equipped with a spring and an adjusting screw, allowing for height and thickness adjustments. There are single spring hinges that open in one direction and double spring hinges that open in both directions. In this article, we will discuss the selection, installation method, and precautions of spring hinges.

1. Selecting Spring Hinges:

When selecting spring hinges, it is important to ensure that they match the door and window frame and leaf. Check if the hinge groove matches the height, width, and thickness of the hinge. Also, verify if the hinge and the screws and fasteners connected to it are compatible. The method of connecting the spring hinge should be suitable for the material of the frame and leaf. For example, for a steel frame wooden door, the side connected to the steel frame should be welded, while the side connected to the wooden door leaf should be fixed with wood screws. It is essential to identify which leaf board should be connected to the fan and which one should be connected to the door and window frame. The shafts of the hinges on the same leaf should be on the same vertical line to prevent the door and window leaf from springing up.

2. Installation Method:

Before installing a spring hinge, determine if the door type is a flat door or a rebated door, and consider the door frame material, shape, and installation direction. Follow these steps for installation:

- Insert a 4mm hexagonal key into the hole at one end of the hinge and open the hinge.

- Install the hinges into the hollowed-out grooves on the door leaf and door frame using screws.

- Close the door leaf and make sure the spring hinges are in the closed state. Insert the hexagonal key again, turn it clockwise to rotate, and hear the sound of the gears meshing. Do not exceed four rotations, as it may damage the spring's elasticity when the door leaf is opened.

- Tighten the hinge, ensuring that the opening angle does not exceed 180 degrees.

- To loosen the hinge, repeat the same operation as step 1.

By following these steps, the spring hinge can be installed properly and provide a more reliable and stable operational effect.

Expanding the

Cabinet hinges are another important element to consider during installation. Here's a detailed guide on how to install cabinet hinges:

1. Measure and Mark:

Measure the size and edges of the cabinet door accurately and mark them properly. This step is crucial to ensure the correct placement of the hinges for smooth operation.

2. Drill Holes:

Drill holes on the door panel according to the marked measurements. The depth of the holes should not exceed 12mm. Careful drilling will prevent any damage to the door panel.

3. Insert Hinges:

Place the hinge into the hinge cup and position it on the door panel hole of the cabinet. Use screws to secure the hinge in place. Ensure that the hinges fit properly into the cup and are tightly fixed.

4. Check Functionality:

Close the cabinet door and check if the hinge functions correctly. The door should open and close smoothly without any resistance or noise. If there are any issues, make the necessary adjustments to achieve optimal functionality.

Precautions:

1. Avoid Sharing Hinges:

To maintain stability, it is best to avoid situations where multiple hinges share the same side panel. If unavoidable, leave enough spacing while drilling to prevent multiple hinges from being fixed at the same position.

2. Tightening Loose Hinges:

If the cabinet door becomes loose over time, it can be easily fixed. Loosen the screw that fixes the hinge base using a screwdriver. Slide the hinge arm to the correct position and then tighten the screws again. This simple adjustment will restore stability to the cabinet door.

3. Determining Margins:

When installing cabinet hinges, determine the size of the cabinet door and the minimum margin required between the doors. The minimum margin value can be found in the cabinet hinge installation instructions. It is important to follow these guidelines for proper installation and functionality.

By following the steps and precautions outlined in this article, the selection and installation of spring hinges and cabinet hinges can be done effectively. Spring hinges provide automatic closure, while cabinet hinges ensure smooth operation and stability. Careful consideration of the door and frame material, accurate measurements, and proper alignment will result in successful installations.

to the Types of Cabinet Door Hinges

When customizing furniture, one important aspect to consider is the type of hinges for cabinet doors. Cabinet door hinges are essential for the smooth operation of the doors and their proper installation. In this article, we will discuss the different types of cabinet door hinges and their installation points.

Types of Cabinet Door Hinges:

1. Ordinary Hinges: These are commonly used for cabinet doors, windows, and doors. They are made of materials such as iron, copper, and stainless steel. However, ordinary hinges do not have the function of spring hinges. After installation, touch beads must be added to prevent the doors from being blown open by the wind.

2. Pipe Hinges: Also known as spring hinges, pipe hinges are used for connecting furniture door panels. They are designed for a specific plate thickness of 16-20mm and are made from galvanized iron or zinc alloy. Pipe hinges come with an adjusting screw that allows for height, width, and thickness adjustments. They also offer various opening angles to match different cabinet door sizes.

3. Door Hinges: Door hinges can be either ordinary or bearing type hinges. The ordinary type is similar to ordinary hinges mentioned earlier. Bearing hinges, on the other hand, are available in copper or stainless steel. Copper bearing hinges are commonly used due to their beautiful and bright style, moderate price, and included screws.

4. Other Hinges: This category includes glass hinges, countertop hinges, and flap hinges. Glass hinges are specifically designed for frameless glass cabinet doors, requiring a glass thickness of no more than 5-6mm.

Installation Points of Cabinet Door Hinges:

1. Check Compatibility: Before installation, ensure that the hinges match the door and window frames and leaves.

2. Verify Hinge Groove: Check if the hinge groove matches the height, width, and thickness of the hinge.

3. Compatible Fasteners: Confirm that the screws and fasteners connected to the hinge are compatible.

4. Appropriate Connection Method: The hinge's connection method should be suitable for the material of the frame and leaf. For example, for steel frame wooden doors, the hinge side connected to the steel frame should be welded, while the side connected to the wooden door leaf should be fixed with wood screws.

5. Symmetrical Leaf Plates: If the hinge's leaf plates are asymmetrical, identify which leaf plate should be connected to the fan and which should be connected to the door and window frame. The side connected to the three sections of the shaft should be fixed to the frame, while the side connected to the two sections of the shaft should be fixed to the frame.

6. Proper Alignment: During installation, ensure that the axes of the hinges on the same leaf are on the same vertical line to prevent the door and window leaves from springing up.

In summary, understanding the types of cabinet door hinges is essential for customization projects. Each hinge type has its unique features and functions to suit different cabinet door requirements. Moreover, paying attention to the installation points will ensure proper and secure hinge installation. By considering these factors, you can choose the right hinges and ensure smooth operation of your cabinet doors.

Piezoelectric actuators are known for their smooth motion, high resolution, high stiffness, and high energy conversion efficiency. They are ideal for precise positioning in engineering applications. However, these actuators typically have only a few to tens of microns of displacement, which may not be sufficient for many applications that require a larger range of motion.

To overcome this limitation, flexible hinges can be used in conjunction with piezoelectric actuators. Flexible hinges provide smooth motion, do not require lubrication, have no backlash or friction, and offer high precision. They are the most suitable method for achieving actuator displacement. Furthermore, the flexible hinge mechanism provides appropriate preload for the piezoelectric actuator, preventing it from being subjected to tensile stress.

There are several typical examples of using piezoelectric element drive and flexible hinge mechanism transmission:

1. Ultra-precision positioning table: The US National Bureau of Standards developed a micro-positioning workbench in 1978 for line width measurement of photomasks. The workbench is driven by piezoelectric elements, and the flexible hinge mechanism is used for displacement amplification. It is compact, works in a vacuum, and can linearly position objects within a working range of 50mm with a resolution of 1nm or better.

2. Scanning tunneling microscope (STM): To expand the measurement range of STM, researchers have developed 2-dimensional ultra-precision worktables driven by a piezoelectrically driven flexible hinge mechanism. These worktables allow for large field measurements. For example, the US National Bureau of Standards reported a 500pm x 500pm STM probe with a 500mm field of view. The X-y workbench is driven by piezoelectric blocks, and the flexible hinge mechanism has a displacement amplification ratio of about 18.

3. Ultra-precision machining: Micro-positioning tool holders composed of piezoelectric elements, flexible hinge mechanisms, and capacitive sensors are used for ultra-precision diamond cutting. The tool holder has a stroke of 5um and a positioning resolution of about 1nm. It is used for precision connection processes like laser welding.

4. Print head: The print head of an impact dot matrix printer utilizes the principle of piezoelectric drive and flexible hinge mechanism transmission. The flexible hinge mechanism amplifies the displacement of the piezoelectric block and drives the movement of the printing needle. Multiple printing needles form the printing head, allowing for the printing of characters composed of dot matrices.

5. Optical auto focus: In automated production, high-precision autofocus systems are required to obtain high-quality images. Traditional motor drives have limited positioning accuracy and are limited by the magnification of the objective lens. Piezoelectric drive with a flexible hinge mechanism offers better repeatability and can focus on objective lenses with high magnification.

6. Piezoelectric motor: Piezoelectric motors can be designed using piezoelectric drive and flexible hinge mechanism transmission. These motors can achieve clamping and stepping rotation or linear motion between the mover and the stator. They can provide high positioning accuracy at low speeds and can withstand certain moments or forces.

7. Active radial air bearings: Active radial air bearings utilize flexible hinge mechanisms and piezoelectric drives to precisely control the radial displacement of a shaft. This improves the motion accuracy of the shaft compared to traditional air bearings.

8. Micro gripper: Micro grippers are used in micro-instrument assembly, biological cell manipulation, and fine surgery. They amplify the displacement of piezoelectric actuators through flexible hinge lever mechanisms to allow for the grasping of tiny objects.

The use of flexible hinges in supporting structures, connection structures, adjustment mechanisms, and measuring instruments is widely applicable in the fields of precision mechanical precision measurement, micron technology, and nanotechnology.

In conclusion, flexible hinges offer numerous advantages in achieving ultra-precise displacement and positioning with piezoelectric actuators. They provide smooth motion, high precision, and no friction or backlash. By using flexible hinge mechanisms to transfer and amplify the displacement of piezoelectric actuators, engineers can achieve larger movements and higher accuracy in a wide range of applications.
