Description

Technical Field

[0001] This application relates to the field of sheet metal stamping technology, and in particular to a sheet metal stamping device that prevents deformation. Background Technology

[0002] Sheet metal parts are characterized by their light weight, high strength, conductivity (which can be used for electromagnetic shielding), low cost, and good mass production performance. They are widely used in the fields of electronics, communications, automotive, and medical devices. Typically, the three most important steps in sheet metal parts manufacturing are shearing, punching / cutting, and bending.

[0003] Existing stamping devices have the problem of inconvenience in removing sheet metal parts after stamping. Sheet metal parts are easily stuck inside the stamping holes, requiring workers to use tools to pry them out. This not only affects work efficiency but may also damage or deform the sheet metal parts, increasing the intensity of manual labor. Therefore, this application proposes a sheet metal stamping device that prevents deformation. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a sheet metal stamping device that prevents deformation, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a sheet metal stamping device for preventing deformation, comprising a stabilizing plate, one end of four return springs fixedly connected to the top of the stabilizing plate, and a lowering plate fixedly connected to the other end of the four return springs, a fixing plate mounted on the top of the lowering plate, a cylinder mounted on the top of the fixing plate, the output shaft of the cylinder fixedly connected to the top of the lowering plate, two sets of positioning components mounted on the bottom of the lowering plate, a stamping block mounted on the bottom of the lowering plate, a stamping hole opened on the top of the stabilizing plate, and a pushing component mounted on the bottom of the stabilizing plate.

[0006] In a preferred embodiment, four positioning rods are fixedly connected to the top of the stabilizing plate, and the four positioning rods are slidably connected to the lower plate, while the fixed plate is fixedly connected to the four positioning rods.

[0007] By adopting the above technical solution, it can be used to position the fixing plate, ensuring that the fixing plate can be stably set above the lowering plate.

[0008] In a preferred embodiment, the positioning component includes two limiting shafts, which are slidably connected to the inner wall of the lower moving plate. A pressure plate is fixedly connected to the bottom end of the two limiting shafts, and one end of a return spring is fixedly connected to the top of the pressure plate. The other end of the return spring is fixedly connected to the bottom of the lower moving plate.

[0009] By adopting the above technical solution, the sheet metal parts can be laid on the top of the stabilizing plate and corresponding to the position of the stamping hole. Then, when the cylinder drives the lower plate and the stamping block to move downward, the pressure plate can move downward first to abut the sheet metal, ensuring that the sheet metal will not easily shift its position during the stamping process.

[0010] In a preferred embodiment, four connecting posts are installed at the bottom of the stabilizing plate, and a base plate is fixedly connected to the bottom of the four connecting posts.

[0011] By adopting the above technical solution, it is possible to position the device and ensure that there is a certain gap between the stabilizing plate and the ground.

[0012] In a preferred embodiment, the pusher assembly includes a movable plate that is slidably connected to the inner wall of the punching hole. The bottom of the movable plate is fixedly connected to the output shaft of an electric push rod, and the bottom of the movable plate is fixedly connected to the top of the base plate.

[0013] By adopting the above technical solution, the driveable electric push rod can move the moving plate up and down on the inner wall of the punching hole, which can then be used to push the stamped sheet metal part away from the inner wall of the punching hole, thereby improving the convenience of removing the material.

[0014] In a preferred embodiment, two stabilizing frames are symmetrically installed on the bottom of the movable plate. Each of the two stabilizing frames has a locking block slidably inserted into its inner wall. The outer sides of each of the two locking blocks are fixedly connected to the output shaft of an electric telescopic rod, and the electric telescopic rod is fixedly connected to the bottom of the stabilizing plate. One side of each locking block overlaps the bottom of the stabilizing plate.

[0015] By adopting the above technical solution, the stabilizing frame and the locking block can lock the moving plate, ensuring that the moving plate can be stably set on the inner wall of the punching hole. This prevents the downward impact force of the punching block from being directly transmitted to the electric push rod, thus ensuring the service life of the electric push rod. Furthermore, driving the electric telescopic rod can move the locking block out of the interior.

[0016] In a preferred embodiment, the fixing plate has a through hole in the middle, and the output shaft of the cylinder is slidably connected to the inner wall of the through hole.

[0017] By adopting the above technical solution, the driveable cylinder can drive the lower plate and the stamping block to move downward, thereby ensuring that the output shaft of the cylinder will not interfere with the fixed plate when moving.

[0018] The beneficial effects of this application are: This anti-deformation sheet metal stamping device uses an electric telescopic rod to move a locking block away from the inner wall of a stabilizing frame, releasing the locking of the moving plate. Then, an electric push rod can be driven to move the moving plate up and down on the inner wall of the stamping hole, thereby pushing the stamped sheet metal part away from the inner wall of the stamping hole. This improves the convenience of removing the material and effectively avoids damage and deformation of parts caused by the lifting of the sheet metal part.

[0019] This anti-deformation sheet metal stamping device uses a cylinder to drive the lower plate and stamping block to move downwards. During stamping, the pressure plate moves downwards first to abut against the sheet metal, ensuring that the sheet metal does not easily shift position during the stamping process and guaranteeing the accuracy of the stamping position.

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0023] Reference Figure 1-4 A sheet metal stamping device for preventing deformation includes a stabilizing plate 1. The top of the stabilizing plate 1 is fixedly connected to one end of four return springs 2, and the other end of the four return springs 2 is fixedly connected to a lowering plate 3. A fixing plate 5 is installed on the top of the lowering plate 3, and a cylinder 6 is installed on the top of the fixing plate 5. The output shaft of the cylinder 6 is fixedly connected to the top of the lowering plate 3. Two sets of positioning components are installed on the bottom of the lowering plate 3, and a stamping block 7 is installed on the bottom of the lowering plate 3. A stamping hole 11 is opened on the top of the stabilizing plate 1, and a pushing component is installed on the bottom of the stabilizing plate 1.

[0024] See Figure 1 - Figure 3The top of the stabilizing plate 1 is fixedly connected with four positioning rods 4, and the four positioning rods 4 are slidably connected to the lower moving plate 3. The fixed plate 5 is fixedly connected to the four positioning rods 4, so that it can be used to position the fixed plate 5 and ensure that the fixed plate 5 can be stably set above the lower moving plate 3.

[0025] See Figure 3 The positioning component includes two limiting shafts 8, which are slidably connected to the inner wall of the reset lower plate 3. The bottom ends of the two limiting shafts 8 are fixedly connected to pressure plates 9, and the top of the pressure plates 9 is fixedly connected to one end of a reset spring 10. The other end of the reset spring 10 is fixedly connected to the bottom of the lower plate 3, so that the sheet metal can be laid on the top of the stabilizing plate 1 and the position corresponding to the stamping hole 11. Then, when the cylinder 6 drives the lower plate 3 and the stamping block 7 to move downward, it can first drive the pressure plate 9 to move downward to abut against the sheet metal, ensuring that the sheet metal will not easily shift position during the stamping process.

[0026] See Figure 1 The bottom of the stabilizing plate 1 is equipped with four connecting columns 12, and the bottom of the four connecting columns 12 is fixedly connected to the base plate 13, which can be used to position the device and ensure that there is a certain gap between the stabilizing plate 1 and the ground.

[0027] See Figure 1 , Figure 3 and Figure 4 The material pushing assembly includes a movable plate 15, which is slidably connected to the inner wall of the punching hole 11. The bottom of the movable plate 15 is fixedly connected to the output shaft of the electric push rod 14. The bottom of the movable plate 15 is fixedly connected to the top of the base plate 13, so that the electric push rod 14 can be driven to move the movable plate 15 up and down on the inner wall of the punching hole 11, thereby pushing the stamped sheet metal part away from the inner wall of the punching hole 11, thereby improving the convenience of material removal.

[0028] See Figure 4 Two stabilizing frames 18 are symmetrically installed at the bottom of the movable plate 15. The inner walls of the two stabilizing frames 18 are slidably inserted with locking blocks 17. The outer sides of the two locking blocks 17 are fixedly connected to the output shaft of the electric telescopic rod 16. The electric telescopic rod 16 is fixedly connected to the bottom of the stabilizing plate 1. One side of the locking block 17 overlaps the bottom of the stabilizing plate 1, so that the stabilizing frames 18 and the locking blocks 17 can lock the movable plate 15, ensuring that the movable plate 15 can be stably set on the inner wall of the punching hole 11. This prevents the downward impact force of the punching block 7 from being directly transmitted to the electric push rod 14, ensuring the service life of the electric push rod 14. Furthermore, driving the electric telescopic rod 16 can move the locking block 17 away from the interior of 19.

[0029] See Figure 1 - Figure 3A through hole is provided in the middle of the fixed plate 5. The output shaft of the cylinder 6 is slidably connected to the inner wall of the through hole, so that the cylinder 6 can drive the lower plate 3 and the stamping block 7 to move downward, thereby ensuring that the output shaft of the cylinder 6 will not interfere with the fixed plate 5 when moving.

[0030] Working principle: First, the sheet metal to be stamped can be placed on the top of the stabilizing plate 1, corresponding to the position of the stamping hole 11. Then, the cylinder 6 can be driven to move the lower plate 3 and the stamping block 7 downward until the stamping block 7 abuts against the inner wall of the stamping hole 11, and then the sheet metal can be stamped. At the same time, the cylinder 6 can drive the lower plate 3 and the stamping block 7 to move downward. During the stamping, the pressure plate 9 can be driven to move downward first to abut against the sheet metal, ensuring that the sheet metal will not easily shift its position during the stamping process, thus ensuring the accuracy of the stamping position. After the stamping is completed, the electric telescopic rod 16 can be driven to move the locking block 17 away from the inner wall of the stabilizing frame 18, thereby releasing the lock on the moving plate 15. Then, the electric push rod 14 can be driven to move the moving plate 15 up and down on the inner wall of the stamping hole 11, which can then be used to push the stamped sheet metal part away from the inner wall of the stamping hole 11, thereby improving the convenience of removing the material.
