Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping machine technology, specifically to a feeding auxiliary correction device for a continuous stamping machine. Background Technology
[0002] A continuous stamping press is a high-efficiency metal processing equipment, mainly used for continuous stamping of metal sheets. It can automatically and continuously complete a series of stamping processes, such as stamping, cutting, and bending. These operations are all completed automatically inside the equipment without manual intervention. As a widely used piece of equipment in industrial production, continuous stamping presses are mainly used for continuous stamping of materials such as metal sheets to manufacture parts of various shapes and specifications.
[0003] Traditional continuous stamping presses rely on simple conveying equipment, such as conveyor belts and rollers, to transport materials to the stamping station. Due to the flatness of the material itself, the precision of the conveying equipment, and the influence of external factors (such as vibration and uneven friction), the material is prone to positional deviation during the feeding process. Once the material position is inaccurate, it will cause the stamping position to shift during the stamping process, resulting in the stamped parts not meeting the design requirements and increasing the defect rate. Utility Model Content
[0004] The purpose of this utility model is to solve the problems of easy deviation during conveying and positional shift caused by stamping.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: It includes a machine body, a stamping device fixedly installed on one side of the machine body, and a correction device fixedly connected to the outer surface of the machine body near the stamping device. The correction device includes a base plate, the lower surface of which is fixedly connected to the machine body. Supports are symmetrically fixedly installed on the upper surface of the base plate. A threaded rod is threaded into the upper end of each support, and a connector is fixedly connected to the bottom end of the threaded rod. A first spring is fixedly sleeved on the outer surface of the connector. An adjustment module is slidably connected between the inner walls of the two supports. A servo motor is fixedly installed on one side of one of the adjustment modules. The output end of the servo motor passes through the adjustment module and is fixedly connected to one end of a correction roller. The bottom end of the first spring is fixedly connected to the adjustment module. A correction roller is fixedly connected to one side of both adjustment modules. A conveyor plate is fixedly installed on the upper surface of the base plate, and multiple conveyor rollers are rotatably connected to the outer surface of the conveyor plate.
[0006] Preferably, the stamping device includes a support frame, an upper template is slidably connected between the inner walls of both sides of the support frame, a cylinder is fixedly installed on the upper surface of the support frame, the output end of the cylinder is fixedly connected to the upper template, a lower template is fixedly installed on the upper surface of one side of the machine body, a plurality of guide posts are fixedly installed on the upper surface of the upper template, one end of the guide post passes through the support frame and is fixedly connected to one side of the machine body, a stamping head is fixedly installed on the lower surface of the upper template, a driven plate is symmetrically slidably connected to the upper surface of the lower template, a clamping plate is fixedly connected to the upper surface of the driven plate, and a telescopic rod is fixedly connected to one side of the clamping plate.
[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0008] 1. This utility model, through the combined use of a stamping device with a correction device, when a deviation occurs in the material feeding position, the servo motor drives the correction roller to rotate, and uses friction to apply lateral force to the material for correction. This correction function can help the material to be in an accurate position when entering the stamping device, improving the accuracy of stamping. When the upper template descends, it cooperates with the inclined surface of the driven plate to push the driven plate to drive the clamping plate to clamp and fix the feeding material. The material is reset by the telescopic rod. Reliable clamping can ensure the consistency and stability of stamping and improve the stamping quality. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Example: Figure 1-3 As shown, this utility model provides a feeding auxiliary correction device for a continuous stamping press, including a machine body 11. A stamping device 12 is fixedly installed on one side of the machine body 11. A correction device 13 is fixedly connected to the outer surface of the machine body 11 near the stamping device 12. The correction device 13 includes a base plate 14. Multiple limiting wheels 17 are fixedly installed on the upper surface of one side of the base plate 14, and the limiting wheels 17 are distributed in a rectangular array. This layout allows the limiting wheels 17 to provide a more comprehensive and uniform limit on one side of the feeding material in the conveying direction. During the feeding process, it can effectively prevent the material from deviating on this side and ensure that the material is conveyed to the stamping position along the correct path. A limiting plate is fixedly installed on the upper surface of the base plate 14 near the stamping device 12, which can provide a final position limit for the feeding material just before it enters the stamping device 12. To prevent excessive material deviation at the end of the conveying process and ensure that the material enters the stamping stage in the correct posture, thus avoiding stamping quality problems caused by improper feeding position and improving the stamping reliability of the entire device, the lower surface of the base plate 14 is fixedly connected to the machine body 11.
[0016] A bracket 18 is symmetrically fixedly mounted on the upper surface of the base plate 14. A threaded rod 20 is threaded into the upper end of the bracket 18, and a connector 22 is fixedly connected to the bottom end of the threaded rod 20. A first spring 23 is fixedly sleeved on the outer surface of the connector 22. An adjustment module 19 is slidably connected between the inner walls of the two brackets 18. A servo motor 25 is fixedly mounted on one side of one of the adjustment modules 19. The output end of the servo motor 25 passes through the adjustment module 19 and is fixedly connected to one end of the correction roller 24. The bottom end of the first spring 23 is connected to the adjustment module. The two adjustment modules 19 are fixedly connected to one side of a correction roller 24. A conveyor plate 15 is fixedly installed on the upper surface of the base plate 14. Multiple conveyor rollers 16 are rotatably connected to the outer surface of the conveyor plate 15. By rotating the threaded rod 20 on the rotating bracket 18, the connector 22 drives the first spring 23 and the adjustment module 19 to move, thereby adjusting the height of the correction roller 24 to match the thickness of the feed material. When the position of the feed material deviates, the servo motor 25 drives the correction roller 24 to rotate, using friction to correct the material position.
[0017] The stamping device 12 includes a support frame 27. An upper template 29 is slidably connected between the inner walls of both sides of the support frame 27. Guide rails are fixedly installed on the inner surfaces of both sides of the support frame 27, and the outer surfaces of the guide rails are slidably connected to the upper template 29. The guide rails provide precise guidance for the up-and-down sliding of the upper template 29, ensuring that the upper template 29 can move smoothly along a fixed trajectory under the drive of the cylinder 30, avoiding shaking or deviation of the upper template 29 during movement, thereby improving the accuracy and stability of stamping. A cylinder 30 is fixedly installed on the upper surface of the support frame 27, and the output end of the cylinder 30 is fixedly connected to the upper template 29. A lower template 28 is fixedly installed on the upper surface of one side of the machine body 11. Multiple guide pillars 31 are fixedly installed on the upper surface of the upper template 29. One end of each guide pillar 31 passes through the support frame 27 and is fixedly connected to one side of the machine body 11. A punch head 32 is fixedly installed on the lower surface of the upper template 29. Slide rails are symmetrically fixedly installed on the upper surface of the lower template 28, and punching grooves are provided for use with the punch head 32. A slider is slidably fitted onto the upper surface of the slide rail, and the upper surface of the slider is fixedly connected to the driven plate 33. The installation of the slide rail and slider on the upper surface of the lower template 28 allows the driven plate 33 to slide smoothly along the slide rail. This not only ensures that the driven plate 33 can accurately move to the designated position when pushed by the upper template 29, achieving reliable clamping of the feed material, but also reduces the friction of the driven plate 33 during movement, improving the flexibility and service life of the device. Simultaneously, the punching grooves provide an accurate punching position for the punch head 32, ensuring smooth punching processing.
[0018] The upper surface of the lower template 28 is symmetrically slidably connected with a driven plate 33. The lower end of the upper template 29 and one side of the driven plate 33 are both inclined surfaces. The upper template 29 and the driven plate 33 are used in conjunction. The inclined surface design of the lower end of the upper template 29 and one side of the driven plate 33 utilizes the principle of inclined surface cooperation. When the cylinder 30 drives the upper template 29 to descend, the inclined surface of the upper template 29 will push the driven plate 33 to slide inward. This structural design realizes that the driven plate 33 moves synchronously during the descent of the upper template 29, thereby enabling the clamping plate 34 to automatically clamp the feed material. This simplifies the structure and operation process of the device and improves work efficiency. The upper surface of the driven plate 33 is fixedly connected with a clamping plate 34. One side of the clamping plate 34 is fixedly connected with a telescopic rod 35. The outer surface of the telescopic rod 35 is fixedly fitted with a second spring 36. The second spring 36 can play the role of buffering and providing elastic force, which can help the upper template 29 to reset and move the clamping plates 34 on both sides while rising.
[0019] Working principle: The base plate 14 of the calibration device 13 is fixed on the machine body 11, and the bracket 18 is symmetrically installed on the upper surface of the base plate 14. By rotating the threaded rod 20, since the threaded rod 20 is threaded into the upper end of the bracket 18, the connector 22 at the bottom end of the threaded rod 20 will drive the first spring 23 and the adjustment module 19 to move up and down. This operation can flexibly adjust the height of the correction roller 24 according to the thickness of the feed material, so that the correction roller 24 can fully contact the material and prepare for the subsequent correction operation. When the position of the feed material deviates, the servo motor 25 starts and drives the correction roller 24 to rotate. The correction roller 24 applies lateral force to the material through friction with the material surface, thereby correcting the position deviation of the material and allowing the material to enter the stamping device 12 along the correct path. The feed material is conveyed forward under the rotation of the conveying roller 16. At the same time, multiple limiting wheels 17 arranged in a rectangular array and fixedly installed on one side of the upper surface of the base plate 14, as well as the limiting plate fixedly installed on the upper surface of the side near the stamping device 12, play a limiting role in the conveying of the material and prevent the material from deviating excessively during the conveying process.
[0020] When the stamping material moves from the straightening device 13 to the stamping device 12, the stamping device 12 is used to stamp the straightened feed material. When the cylinder 30 is started, its output end drives the upper template 29 to slide up and down within the support frame 27. During the up and down movement of the upper template 29, the guide post 31 plays a guiding role, ensuring the accurate movement trajectory of the upper template 29 and improving the stamping accuracy. When the upper template 29 descends, since the lower end of the upper template 29 and one side of the driven plate 33 are both inclined surfaces and the two work together, the upper template... 29 will push the driven plate 33 to slide inward on the slide rail on the lower template 28. The driven plate 33 will drive the clamping plate 34 to move inward. Through the buffer of the telescopic rod 35 and the second spring 36, the feeding material is clamped and fixed. At the same time, the punch head 32 descends into the punching groove opened on the lower template 28 to punch the material. When the upper template 29 rises, the driven plate 33 slides outward under the elastic restoring force of the second spring 36, releasing the clamping of the material so that the next feeding and punching operation can be carried out.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
