Description

Technical Field

[0001] The utility model relates to the technical field of non-standard part bending, and specifically relates to a clamping device for non-standard part bending. Background Technique

[0002] Non-standard parts, that is, non-standard components, are a concept relative to standard parts. In the manufacturing industry, standard parts refer to components produced according to national standards or industry standards, which have universality and interchangeability. Non-standard parts refer to those components that are not produced according to standards, or although produced according to standards, have special requirements in terms of size, shape, material, etc. These components need to be customized according to specific product designs or production processes, so they do not have universality and interchangeability.

[0003] The Chinese patent with the publication number CN216461330U discloses a clamping device for integrated rod bending, including a positioning unit, with a pair of them arranged on one side of the bending machine, including a first linear mechanism whose direction is perpendicular to the folding line of the steel plate, and a second linear mechanism whose direction is parallel to the length direction of the bending machine is arranged at the upper end of the first sliding end; a clamping plate unit is arranged at one end of the positioning unit, including a third linear mechanism arranged vertically, a pair of rotating mechanisms are arranged on one side of the second sliding end of the third linear mechanism, a fourth linear mechanism is arranged at one end of the rotating mechanism, and a pneumatic clamping mechanism is arranged at one end of its output shaft.

[0004] The above-mentioned existing technical solutions have the following defects: When clamping non-standard parts, due to the uneven shape and weight distribution of non-standard parts, the clamping force may be unevenly distributed between the clamping points. This may reduce the clamping stability and increase the risk of displacement or deformation of non-standard parts during the bending process.

[0005] Therefore, we propose a clamping device for non-standard part bending to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a clamping device for non-standard part bending to solve the problem of insufficient clamping stability proposed in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A clamping device for non-standard part bending, including a collection box and a base fixed on the upper surface of the collection box, a blanking structure is arranged inside the collection box, a frame is fixed on the upper surface of the collection box, a bending mechanism is arranged on the right side of the frame, and a clamping mechanism is arranged on the upper surface of the base;

[0008] The clamping mechanism includes a clamping unit and a pressing unit;

[0009] The clamping unit includes a workbench, a placement groove, a lead screw nut, a fixing plate, a motor, a threaded rod, a cylinder, and a flexible clamp. The bottom of the workbench is fixedly connected to the upper surface of the base. The placement groove is opened on both sides of the upper surface of the workbench. The threaded rod is connected inside the placement groove. The lead screw nut is threadedly connected to the threaded rod. The bottom of the fixing plate is fixedly connected to the upper surface of the lead screw nut. The cylinder is arranged on the side where the fixing plates are close to each other. The output end of the cylinder is connected to the flexible clamp. The output end of the motor is connected to the threaded rod through a coupling.

[0010] The pressing unit includes an electric push rod and a pressing plate. The electric push rod is fixedly connected to the frame, and the output end of the electric push rod is connected to the upper surface of the pressing plate.

[0011] Preferably, the blanking structure includes an outlet, a collection port, a first blanking plate, a second blanking plate, and a third blanking plate. The outlet is opened at the lower left side of the collection box, and the collection port is opened at the upper right side of the collection box. The first blanking plate, the second blanking plate, and the third blanking plate are respectively fixedly connected inside the collection box. A buffer assembly is arranged on the left side of the first blanking plate and the right side of the second blanking plate. The reasonable layout of the outlet and the collection port enables the non-standard parts to smoothly enter the collection box after being bent, and at the same time facilitates the rapid addition of new workpieces from the collection port, improving the work efficiency and automation degree.

[0012] Preferably, the buffer assembly includes a chute, a slider, and a damper. The chute is opened on the inner wall of the collection box. The slider is slidably connected inside the chute. The damper is arranged below the slider. The outer sides of the slider are respectively fixedly connected to the left side of the first blanking plate and the right side of the second blanking plate, effectively reducing the impact force of the workpiece during the falling process, protecting the workpiece from damage, and at the same time ensuring the stability and smoothness of the blanking process.

[0013] Preferably, the first blanking plate, the second blanking plate, and the third blanking plate are respectively connected to the inside of the collection box at a certain angle. The first blanking plate and the third blanking plate are inclined in one direction, and the second blanking plate is inclined in another direction, enabling the workpiece to slide smoothly along the preset path and reducing collisions and damages.

[0014] Preferably, a non-slip pad is fixedly connected to the lower surface of the pressing plate. The non-slip pad is made of silicone material. The silicone non-slip pad not only provides good anti-slip effect but also protects the surface of the workpiece from scratches or indentations during pressing, ensuring the integrity of the workpiece.

[0015] Preferably, the length of the pressing plate is equal to the length of the workbench, ensuring that the pressing plate can fully cover the workbench and apply uniform pressure to the workpiece.

[0016] Preferably, the flexible clamp is made of a rubber material with high strength and high wear resistance, and has anti-slip textures on its surface to ensure that non-standard parts of different materials and shapes will not slide or be damaged during the clamping process. The anti-slip textures increase the friction between the flexible clamp and the workpiece, preventing the workpiece from sliding or falling off during the clamping process, and improving the stability and safety of the clamping.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. For the clamping device for bending non-standard parts, through the reasonable layout of the outlet and the collection port, the bent workpiece can enter the collection box through the collection port, significantly improving the work efficiency, reducing manual intervention, and enhancing the automation level of the overall production process.

[0019] 2. For the clamping device for bending non-standard parts, the design of the pressing unit ensures that the pressing plate can fully cover the workbench and apply uniform pressure to the workpiece. Moreover, the flexible clamp in the clamping unit is made of a rubber material with high strength and high wear resistance and has anti-slip textures, which not only enhances the stability of the clamping, prevents the workpiece from sliding or falling off during the clamping process, but also improves the safety of the operation. The softness of the rubber material also reduces the direct hard contact with the workpiece, avoiding indentations or damages on the surface of the workpiece.

[0020] 3. For the clamping device for bending non-standard parts, the buffer assembly in the blanking structure, including the chute, the slider and the damper, effectively reduces the impact force and vibration of the workpiece during the falling process, avoiding damage to the workpiece due to collision or vibration. At the same time, the different-angle inclined designs of the first, second and third blanking plates enable the workpiece to slide smoothly along the preset path, further reducing the risk of collision and damage and protecting the integrity of the workpiece.

[0027] Please refer to Figures 1 - 4 , the present invention provides a technical solution:

[0028] Embodiment 1:

[0029] A clamping device for bending non-standard parts includes a collection box 1 and a base 6 fixed on the upper surface of the collection box 1. The collection box 1 serves as the support and collection platform for the entire device. The collection box 1 not only stably supports components such as the base 6 and the frame 3, but also effectively collects and organizes the bent workpieces through the internal blanking structure, improving the cleanliness and work efficiency of the production site. A blanking structure is provided inside the collection box 1, a frame 3 is fixed on the upper surface of the collection box 1, a bending mechanism is arranged on the right side of the frame 3, and a clamping mechanism is arranged on the upper surface of the base 6;

[0030] The clamping mechanism includes a clamping unit and a pressing unit;

[0031] The clamping unit includes a workbench 2, a placement groove 201, a lead screw nut 202, a fixing plate 203, a motor 204, a threaded rod 205, a cylinder 206, and a flexible clamp 207. The bottom of the workbench 2 is fixedly connected to the upper surface of the base 6, providing a platform for workpiece placement and operation, and ensuring the stability of the workpiece during the bending process. The placement groove 201 is opened on both sides of the upper surface of the workbench 2. The threaded rod 205 is connected inside the placement groove 201. The lead screw nut 202 is threadedly connected to the threaded rod 205. The bottom of the fixing plate 203 is fixedly connected to the upper surface of the lead screw nut 202. The cylinder 206 is arranged on one side where the fixing plates 203 are close to each other. The output end of the cylinder 206 is connected to the flexible clamp 207. The flexible clamp 207 is made of a rubber material with high strength and high wear resistance, and its surface is provided with anti-slip texture. The output end of the motor 204 is connected to the threaded rod 205 through a coupling, jointly constituting the adjustment mechanism of the clamping unit. By driving the motor 204, the position of the flexible clamp 207 can be accurately adjusted to adapt to workpieces of different sizes and shapes, improving the adaptability and flexibility of the device;

[0032] The pressing unit includes an electric push rod 401 and a pressing plate 402. The lower surface of the pressing plate 402 is fixedly connected with an anti-slip pad, and the length of the pressing plate 402 is equal to the length of the workbench 2. The electric push rod 401 is fixedly connected to the frame 3, and the output end of the electric push rod 401 is connected to the upper surface of the pressing plate 402. The electric push rod 401 provides a stable power source, and the pressing plate 402, through its design with a length equal to that of the workbench 2, ensures that it can fully cover the workbench 2 and apply uniform pressure to the workpiece, improving the accuracy and consistency of bending. At the same time, the anti-slip pad on the lower surface of the pressing plate 402 further protects the surface of the workpiece from scratches or indentations.

[0033] Embodiment 2:

[0034] On the basis of Embodiment 1, the blanking structure includes an outlet 101, a collection port 102, a first blanking plate 501, a second blanking plate 502, and a third blanking plate 503. The outlet 101 is opened at the lower left side of the collection box 1, and the collection port 102 is opened at the upper right side of the collection box 1. The reasonable layout enables the bent workpiece to smoothly enter the collection box 1 through the collection port 102 and then be collected through the outlet 101, improving the work efficiency and automation degree. The first blanking plate 501, the second blanking plate 502, and the third blanking plate 503 are respectively fixedly connected to the inside of the collection box 1. The first blanking plate 501, the second blanking plate 502, and the third blanking plate 503 are respectively connected to the inside of the collection box 1 at a certain angle. The first blanking plate 501 and the third blanking plate 503 are inclined in one direction, and the second blanking plate 502 is inclined in another direction. These blanking plates are inclined and connected to the inside of the collection box 1 at different angles, providing a preset sliding path for the workpiece and reducing the collision and damage of the workpiece during the falling process. Buffer components are provided on the left side of the first blanking plate 501 and the right side of the second blanking plate 502. The buffer components include a chute 103, a slider 104, and a damper 105. The chute 103 is opened on the inner wall of the collection box 1. The slider 104 is slidably connected to the inside of the chute 103. The damper 105 is arranged below the slider 104. The outside of the slider 104 is respectively fixedly connected to the left side of the first blanking plate 501 and the right side of the second blanking plate 502. Through the buffering effect of the damper 105, the impact force of the workpiece during the falling process is effectively reduced, protecting the workpiece from damage.

[0035] Working principle: The workpiece is placed on the workbench 2 and clamped on both sides by the flexible clamps 207. The cylinder 206 pushes the flexible clamps 207, and a rubber material with high strength, high wear resistance, and anti-slip texture is used to clamp the workpiece firmly, ensuring that the workpiece does not slide during the bending process. After clamping, the motor 204 drives the threaded rod 205 to rotate, driving the screw nut 202 to move on the threaded rod, thereby adjusting the positions of the fixed plate 203 and the cylinder 206, and further adjusting the clamping width of the flexible clamps 207 to adapt to workpieces of different sizes. At this time, the pressing unit works synchronously, and the electric push rod 401 pushes the pressing plate 402 downward to apply a uniform pressure to the workpiece.

[0036] The bending mechanism is located on the right side of the frame 3 and is aligned with the workpiece on the workbench 2. The bending mechanism is activated to perform a bending operation on the workpiece. After bending, the workpiece enters the inside of the collection box 1 through the collection port 102. The workpiece slides down along the preset inclined paths of the first blanking plate 501, the second blanking plate 502, and the third blanking plate 503. During the process, it is buffered by the damper 105 to reduce the impact force and protect the workpiece from damage. Finally, the workpiece is smoothly discharged from the outlet 101 of the collection box, completing the entire bending and blanking process.
