Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and in particular to a hinge processing machine tool. Background Technology

[0002] A hinge, or hinge assembly, is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can be composed of movable components or made of foldable materials, and their quality directly affects the performance and lifespan of the hinge. Traditional machine tools lack effective corner fixing and protection measures when pressing hinge plates. During the pressing process, the edges and corners of the hinge plate are prone to displacement, leading to inaccurate bending angles and affecting the installation and use of the hinge. Furthermore, directly bending the hinge plate at large angles can easily cause breakage or cracks, reducing the product yield. Summary of the Invention

[0005] As a preferred embodiment of the present invention, the roller assembly includes a cylinder connected to the bottom end of the top rod, and a damping elastic plate is installed between the cylinder and the arc-shaped pressure plate.

[0006] As a preferred embodiment of the present invention, the surface of the arc-shaped pressure plate near the hinge plate is covered with a thin film to prevent pressing and sticking.

[0007] As a preferred embodiment of the present invention, the surface of the mounting plate is provided with an exhaust mechanism, the exhaust mechanism including an air pump fixedly installed on one side of the mounting plate, the input end of the air pump communicating with the internal cavity of the pad, a plurality of spiral blades being rotatably installed inside the pad, and a plurality of air suction holes being opened on the surface of the pad near the hinge plate.

[0008] As a preferred embodiment of the present invention, the output end of the air pump is connected to an air outlet pipe, the free end of the air outlet pipe is connected to a cylinder through the internal space of the top rod, multiple branch pipes are connected to the surface of the cylinder near the arc-shaped pressure plate, a cooling water bag is provided on the surface of the cylinder near the branch pipes, and multiple cooling grooves are formed on the surface of the arc-shaped pressure plate near the cooling water bag.

[0009] As a preferred embodiment of the present invention, a breathable plate is fixedly installed inside the cylinder, and a rotating ring is provided between the cylinder and the breathable plate. Multiple carbon balls for odor adsorption are installed inside the breathable plate, and the carbon balls are supported and stabilized by multiple stabilizing components.

[0010] As a preferred embodiment of the present invention, a pre-bending mechanism is provided on both sides of the mounting plate. The pre-bending mechanism includes a fixed plate rotatably mounted on the bottom end of the mounting plate. A second spring is fixedly installed between the fixed plate and the mounting plate. A sliding groove is provided on the surface of the fixed plate. A slider is slidably mounted inside the sliding groove. A connecting rod is rotatably mounted on the surface of the slider. A clamping plate is rotatably mounted on the free end of the connecting rod and is inserted into one end of the hinge plate. A third spring is fixedly installed between the connecting rod and the slider.

[0011] As a preferred embodiment of the present invention, a fixing block is fixedly installed inside the slide groove, a first spring is fixedly installed between the fixing block and the slider, and a limit rod is fixedly installed on the surface of the slider, with the limit rod sliding through the fixing block.

[0012] As a preferred embodiment of the present invention, a sliding plate for resisting sliding is installed on the surface of the clamping plate near the hinge plate, and the cross section of the clamping plate is concave. An anti-slip pad is fixedly installed on the surface of the support frame near the pad plate, the anti-slip pad is embedded on the back of the pad plate, and the cross section of the pad plate is V-shaped.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention provides telescopic support members and clamping plates on both sides of the arc-shaped pressure plate, with friction plates between the clamping plates and the corners of the hinge plate. During the bending process, the clamping plates can effectively fix the corners of the hinge plate and prevent them from shifting. Combined with the arc-shaped pressure plate, the bending angle and shape can be precisely controlled, which greatly improves the bending accuracy of the hinge, reduces the product defect rate caused by inaccurate bending, and improves the overall product quality.

[0014] 2. This invention connects an air pump to the internal cavity and suction holes of the pad, allowing for timely extraction of air between the hinge plate and the pad during bending. This prevents air bubbles from forming due to residual air, which would affect the surface quality of the hinge plate. Simultaneously, the air output from the air pump enters the cylinder through the outlet pipe and is then blown onto the arc-shaped pressure plate through the branch pipe. Combined with the cooling water bag and cooling tank, this effectively removes the heat generated during bending, preventing the hinge plate from deforming due to overheating and ensuring the stability and continuity of production.

[0015] 3. This invention covers the surface of the curved pressure plate near the hinge plate with a film to prevent pressing and sticking. During the bending process, the film can effectively isolate the hinge plate and the curved pressure plate, avoiding direct contact and adhesion. This not only protects the surface quality of the hinge plate and reduces damage caused by adhesion, but also reduces the maintenance frequency and cost of the equipment and improves production efficiency.

[0016] 4. This invention, by setting a breathable plate and carbon balls inside the cylinder, allows the carbon balls to adsorb odor molecules in the gas as it flows through the cylinder during the operation of the air pump, effectively removing the odor generated during the bending process, creating a good working environment, reducing the harm of odor to the health of operators, and meeting the requirements of modern industrial production for environmental protection and health.

[0017] 5. This invention provides a pre-bending mechanism on both sides of the mounting plate. Before the formal bending, the elastic action of the second spring, the first spring, and the third spring, as well as the sliding of the slider in the groove and the rotational cooperation between the connecting rod and the clamping plate, can pre-bend one end of the hinge plate. Pre-bending allows the hinge plate to better adapt to bending stress during the formal bending, reducing the risk of breakage or cracking, thereby improving the product qualification rate and reducing production costs.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-8 This invention provides a hinge processing machine tool, including a machine frame 1, a support frame 3 mounted on the top of the machine frame 1, a pad 4 mounted on the top of the support frame 3, an mounting plate 2 mounted on one side of the machine frame 1, a hydraulic cylinder 7 fixedly mounted on the top of the mounting plate 2, a pressure plate mechanism 6 provided on the output shaft of the hydraulic cylinder 7, a hinge plate 5 provided between the pressure plate mechanism 6 and the pad 4, the pressure plate mechanism 6 including a long plate 61 fixedly mounted on the output shaft of the hydraulic cylinder 7, a push rod 62 fixedly mounted on the bottom end of the long plate 61, a roller assembly 63 provided on the bottom end of the push rod 62, an arc-shaped pressure plate 65 provided on the bottom end of the roller assembly 63, telescopic support members 69 rotatably mounted on both sides of the arc-shaped pressure plate 65, a clamping plate 68 rotatably mounted on the free end of the telescopic support member 69, and the clamping plate 68 is located at the corner of the hinge plate 5, and a friction plate 67 is provided between the clamping plate 68 and the hinge plate 5.

[0022] In the bending process, the hinge plate 5 is first placed between the arc-shaped pressure plate 65 and the pad 4. Then, the hydraulic cylinder 7 is activated, which moves the long plate 61, which in turn moves the roller assembly 63. The roller assembly 63 then moves the arc-shaped pressure plate 65, thus bending the hinge plate 5. During the bending process, the clamping plate 68 and the telescopic support 69 can accurately position and fix the edges and corners of the hinge plate 5, preventing displacement and ensuring bending accuracy and consistency. The friction plate 67 acts as a buffer and protector between the clamping plate 68 and the hinge plate 5, preventing the clamping plate 68 from directly contacting the hinge plate 5 and causing scratches or damage, thereby improving product quality.

[0023] In some embodiments, the roller assembly 63 includes a cylinder 631 connected to the bottom end of the top rod 62, and a damping elastic plate 64 is installed between the cylinder 631 and the arc-shaped pressure plate 65.

[0024] When the hydraulic cylinder 7 drives the push rod 62 to press down, the cylinder 631 moves downward accordingly. The damping elastic plate 64 can absorb and disperse the pressure, reduce the vibration and impact during the bending process, make the bending process more stable, avoid the hinge plate 5 from breaking or deforming due to sudden pressure changes, make the pressure of the arc-shaped pressure plate 65 on the hinge plate 5 more uniform and stable, improve the bending quality, and make the bending angle and shape of the hinge plate 5 more in line with the requirements.

[0025] In some embodiments, the surface of the arc-shaped pressure plate 65 near the hinge plate 5 is covered with a film 66 to prevent pressure adhesion.

[0026] Specifically, a thin film 66 is wrapped around the surface of the arc-shaped pressure plate 65 near the hinge plate 5 to prevent pressing and sticking. When the arc-shaped pressure plate 65 is pressed down and comes into contact with the hinge plate 5, the film 66 is between the two, preventing them from making direct contact. This effectively avoids the hinge plate 5 and the arc-shaped pressure plate 65 from sticking together during the bending process, reduces damage to the surface of the hinge plate 5, and improves the appearance quality and pass rate of the product.

[0027] In some embodiments, the surface of the mounting plate 2 is provided with an exhaust mechanism 9, which includes an air pump 91 fixedly installed on one side of the mounting plate 2. The input end of the air pump 91 is connected to the internal cavity of the pad 4. Multiple spiral blades 96 are rotatably installed inside the pad 4. Multiple suction holes 97 are opened on the surface of the pad 4 near the hinge plate 5.

[0028] When the air pump 91 is working, it draws air from between the pad 4 and the hinge plate 5 into the internal cavity of the pad 4 through the suction hole 97. The rotation of the spiral blade 96 enhances the airflow and mixing, promptly removing air from between the pad 4 and the hinge plate 5. This prevents air bubbles from forming during bending, thus avoiding defects on the surface of the hinge plate 5, improving the surface quality of the product, and ensuring better fit between the hinge plate 5 and the pad 4. This also ensures uniform stress on the hinge plate 5 during bending, improving the accuracy and stability of the bending process. Furthermore, the air pump 91 can discharge the debris generated during drilling, preventing it from affecting the subsequent bending accuracy of the hinge plate 5.

[0029] In some embodiments, the output end of the air pump 91 is connected to an air outlet pipe 92, and the free end of the air outlet pipe 92 is connected to the cylinder 631 through the internal space of the top rod 62. Multiple branch pipes 93 are connected to the surface of the cylinder 631 near the arc-shaped pressure plate 65. A cooling water bag 94 is provided on the surface of the cylinder 631 near the branch pipes 93, and multiple cooling grooves 95 are opened on the surface of the arc-shaped pressure plate 65 near the cooling water bag 94.

[0030] During the bending process, the hinge plate 5 generates heat. The gas discharged by the air pump 91 enters the cylinder 631 through the air outlet pipe 92, and then blows onto the arc-shaped pressure plate 65 through the branch pipe 93. Through the blowing of gas and the cooling effect of the cooling water bag 94, the heat of the arc-shaped pressure plate 65 and the hinge plate 5 can be removed in time, preventing the hinge plate 5 from deforming or degrading due to overheating, and ensuring the bending quality.

[0031] In some embodiments, a breathable plate 633 is fixedly installed inside the cylinder 631, and a rotating ring 632 is provided between the cylinder 631 and the breathable plate 633. A plurality of carbon balls 634 for absorbing odors are installed inside the breathable plate 633, and the carbon balls 634 are supported and stabilized by a plurality of stabilizing components 635.

[0032] When the gas passes through the cylinder 631, the gas forms a certain rotational flow inside the cylinder 631 under the action of the rotating ring 632, which increases the contact area between the gas and the permeable plate 633, so that the carbon ball 634 can fully adsorb odor molecules in the gas, improve the working environment, and protect the health of the operators. In addition, the stabilizing component 635 includes multiple support rods for support, which can ensure that the carbon ball 634 will not shake or fall off during the operation of the equipment, and ensure the stability and durability of the adsorption effect.

[0033] In some embodiments, pre-bending mechanisms 8 are provided on both sides of the mounting plate 2. The pre-bending mechanism 8 includes a fixed plate 81 rotatably mounted on the bottom end of the mounting plate 2. A second spring 85 is fixedly mounted between the fixed plate 81 and the mounting plate 2. A groove 82 is provided on the surface of the fixed plate 81. A slider 87 is slidably mounted inside the groove 82. A connecting rod 88 is rotatably mounted on the surface of the slider 87. A clamping plate 89 is rotatably mounted on the free end of the connecting rod 88, and the clamping plate 89 is inserted into one end of the hinge plate 5. A third spring 86 is fixedly mounted between the connecting rod 88 and the slider 87.

[0034] Before bending, the hinge plate 5 is inserted into the clamping plates 89 at both ends. The elastic force of the second spring 85 and the third spring 86 causes the clamping plates 89 to generate a pre-tightening force on the hinge plate 5, achieving a pre-bending effect. Pre-bending the hinge plate 5 makes it easier to achieve the required bending angle when bending it in the formal bending process, reducing the resistance during the formal bending and lowering the risk of the hinge plate 5 breaking. By adjusting the elastic force of the springs and the position of the clamping plates 89, the pre-bending requirements of hinge plates 5 of different specifications and sizes can be adapted, improving the versatility of the equipment.

[0035] In some embodiments, a fixing block 83 is fixedly installed inside the slide groove 82, a first spring 84 is fixedly installed between the fixing block 83 and the slider 87, a limit rod is fixedly installed on the surface of the slider 87, and the limit rod slides through the fixing block 83.

[0036] When the slider 87 slides in the groove 82, the first spring 84 provides elastic force, and the limiting rod restricts the sliding range of the slider 87, ensuring the stability and accuracy of the slider 87's movement. It can precisely control the sliding distance of the slider 87, thereby precisely controlling the pre-tightening force of the clamping plate 89 on the hinge plate 5 and improving the pre-bending accuracy.

[0037] In some embodiments, a sliding plate for resisting sliding is installed on the surface of the clamping plate 89 near the hinge plate 5, and the cross section of the clamping plate 89 is concave.

[0038] During the pre-bending process, the sliding plate contacts and slides relative to the surface of the hinge plate 5. The concave cross-section can better wrap one end of the hinge plate 5, increasing the contact area between the clamping plate 89 and the hinge plate 5. The use of the sliding plate reduces the direct friction between the clamping plate 89 and the hinge plate 5, reduces the wear on the surface of the hinge plate 5, and improves product quality. At the same time, it also allows the clamping plate 89 in the pre-bending mechanism 8 to detach after the formal bending, avoiding affecting the bending effect.

[0039] In some embodiments, an anti-slip pad is fixedly installed on the surface of the support frame 3 near the pad 4. The anti-slip pad is embedded on the back of the pad 4, and the cross-section of the pad 4 is V-shaped.

[0040] Among them, the anti-slip pad increases the friction between the support frame 3 and the pad 4, preventing the pad 4 from sliding during use; the V-shaped cross-section of the pad 4 can better fit the bending part of the hinge plate 5, providing uniform support for the hinge plate 5, reducing the deformation of the hinge plate 5 during the bending process, and improving product quality.

[0041] In some embodiments, processing plates 101 are fixedly installed on both sides of the machine tool frame 1, and a plurality of drilling components 102 for drilling hinges are provided at the bottom end of the processing plates 101.

[0042] When the machine tool is working, the drilling component 102 is activated to drill holes in the surface of the hinge plate 5, which facilitates the subsequent installation and use of the hinge plate 5. The drilling component 102 includes a motor, a drill bit body, and a guide sleeve. First, the motor drives the drill bit to rotate, and the guide sleeve positions the drill bit inlet to ensure the initial position accuracy. The drill bit rotates to cut the workpiece, and the guide sleeve dynamically constrains the radial displacement of the drill bit, transmitting the radial force to the hinge plate 5, thereby realizing the drilling of the hinge plate 5.

[0043] Working principle: When bending the hinge plate 5, the hinge plate 5 is first placed between the arc-shaped pressure plate 65 and the pad plate 4. Then, the hydraulic cylinder 7 is activated, which moves the long plate 61. The long plate 61 moves the roller assembly 63, which in turn moves the arc-shaped pressure plate 65, thus bending the hinge plate 5. Before bending, both ends of the hinge plate 5 are inserted into the clamping plates 89 at both ends. The elastic force of the second spring 85 and the third spring 86 causes the clamping plates 89 to generate a pre-tightening force on the hinge plate 5, achieving a pre-bending effect. Pre-bending the hinge plate 5 makes it easier to achieve the required bending angle during the formal bending, reducing the resistance during the formal bending and lowering the risk of hinge plate 5 breakage. During the subsequent bending process, the clamping plate 68 and the telescopic support 69 can accurately position and fix the edges and corners of the hinge plate 5, preventing the hinge plate 5 from shifting during the bending process and ensuring the accuracy and consistency of the bending. Furthermore, the drilling component 102 can drill holes in the surface of the hinge plate 5, enabling the machine tool to integrate drilling and bending of the hinge plate 5, achieving rapid processing and forming.

[0044] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
