Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a leak-proof structure for punch press blanking. Background Technology

[0002] Blanking in a punch press refers to the process of punching the finished product out of the die and cutting off the scrap material during stamping. It is a crucial step in the punch press process. Typically, the blanking device works in coordination using pneumatic, hydraulic, and mechanical methods to remove the finished product from the die and cut off the scrap. The precision and efficiency of the blanking operation have a significant impact on the accuracy and quality of the finished product.

[0003] When punching parts are being cut, they are transported by a slide. Existing slides lack guiding function and cannot store a certain amount of parts for centralized transport. The purpose of this is to better carry out packaging operations. Therefore, a leak-proof structure for punching parts is needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems raised by the prior art and to propose a leak-proof material feeding structure for punch presses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A material leakage prevention structure for punch press blanking includes a support plate, a fixed plate fixedly connected to the top of the support plate, an inclined plate fixedly connected to the inner wall of the fixed plate, a blanking plate rotatably connected to the inner wall of the fixed plate, a pair of flexible bending plates rotatably connected to the inner wall of the blanking plate, a guide plate fixedly connected to the upper surface of the blanking plate, a controller fixedly connected to the surface of the fixed plate, and a blanking protection mechanism provided on the lower surface of the blanking plate.

[0007] Preferably, the material discharge protection mechanism includes an electric telescopic rod fixedly connected to the lower surface of the material discharge plate, a pair of racks slidably connected to the lower surface of the material discharge plate, gears fixedly connected to the bottom ends of the pair of flexible bending plates, the racks meshing with the gears, a common driving plate fixedly connected to the opposite surfaces of the pair of racks, and the output end of the electric telescopic rod fixedly connected to the surface of the driving plate.

[0008] Furthermore, a connecting plate is fixedly connected to the inner wall of the flexible bending plate, and a pressure sensor is fixedly connected to the surface of the connecting plate.

[0009] Preferably, a crescent plate is fixedly connected to the surface of the fixing plate, and a ring plate is fixedly connected to the surface of the blanking plate.

[0010] Furthermore, the surface of the crescent plate is provided with multiple positioning holes, and the inner wall of one of the positioning holes is connected to the same positioning pin, and the positioning pin is adapted to the positioning hole.

[0011] Preferably, a protective plate is fixedly connected to the surface of the blanking plate, a baffle is slidably connected to the inner wall of the protective plate, and a lead screw is rotatably connected to the inner wall of the protective plate, with the surface of the lead screw threadedly connected to the inner wall of the baffle.

[0012] The beneficial effects of this utility model are as follows:

[0013] The stamped material is blocked by a pair of flexible bending plates for storage. When a certain weight of stamped parts accumulates on the flexible bending plates, the plates deform under pressure and come into contact with the pressure sensor. At this time, the output end of the electric telescopic rod drives the drive plate to move, causing a pair of gears to reverse relative to each other, which in turn drives a pair of flexible bending plates to reverse relative to each other for quantitative discharge. At the same time, the guide plate can prevent parts from slipping off the discharge plate and leaking during packaging. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-5 A material leakage prevention structure for punch press blanking includes a support plate 1, a fixing plate 2 fixedly connected to the top of the support plate 1, an inclined plate 20 fixedly connected to the inner wall of the fixing plate 2, a blanking plate 4 rotatably connected to the inner wall of the fixing plate 2, a pair of flexible bending plates 6 rotatably connected to the inner wall of the blanking plate 4, a guide plate 5 fixedly connected to the upper surface of the blanking plate 4, a controller 3 fixedly connected to the surface of the fixing plate 2, and a blanking protection mechanism provided on the lower surface of the blanking plate 4.

[0022] By setting the inclined plate 20, the stamped parts can slide into the blanking plate 4. By setting the controller 3, the start and stop of the electric telescopic rod 10 are controlled. By setting a pair of flexible bending plates 6, the material in the blanking plate 4 is blocked. Under a certain pressure, the flexible bending plates 6 are deformed. By setting the feeding protection mechanism, quantitative protection is provided during feeding.

[0023] In this utility model, reference is made to Figure 4 The material discharge protection mechanism includes an electric telescopic rod 10 fixedly connected to the lower surface of the material discharge plate 4. A pair of racks 11 are slidably connected to the lower surface of the material discharge plate 4. Gears 9 are fixedly connected to the bottom ends of a pair of flexible bending plates 6. The racks 11 mesh with the gears 9. The same driving plate 12 is fixedly connected to the opposite surfaces of the pair of racks 11. The output end of the electric telescopic rod 10 is fixedly connected to the surface of the driving plate 12.

[0024] By setting an electric telescopic rod 10, its output end drives the drive plate 12 to move, which in turn drives a pair of racks 11 to slide, adjusting the rotation angle of a pair of gears 9, so that a pair of flexible bending plates 6 move away from each other to discharge materials.

[0025] In this utility model, reference Figure 3 A connecting plate 7 is fixedly connected to the inner wall of the flexible bending plate 6, and a pressure sensor 8 is fixedly connected to the surface of the connecting plate 7.

[0026] By setting the connecting plate 7 and installing the pressure sensor 8, when the bending pressure of the flexible bending plate 6 reaches the set level, it contacts the surface of the pressure sensor 8 and triggers the pressure sensor 8.

[0027] In this utility model, reference Figure 5 The surface of the fixed plate 2 is fixedly connected to a crescent plate 18, and the surface of the blanking plate 4 is fixedly connected to a ring plate 16.

[0028] The ring plate 16 is set to ensure the stable installation of the positioning pin 17, and the crescent plate 18 is set to facilitate the insertion and fixing of the positioning pin 17.

[0029] In this utility model, reference Figure 5 The surface of the crescent plate 18 is provided with multiple positioning holes 19. The ring plate 16 is connected to the inner wall of one of the positioning holes 19 with the same positioning pin 17. The positioning pin 17 is adapted to the positioning hole 19.

[0030] The positioning hole 19 is set to cooperate with the positioning pin 17 to position the blanking plate 4 and prevent it from rotating.

[0031] In this utility model, reference Figure 4 A guard plate 13 is fixedly connected to the surface of the blanking plate 4. A baffle 15 is slidably connected to the inner wall of the guard plate 13. A lead screw 14 is rotatably connected to the inner wall of the guard plate 13. The surface of the lead screw 14 is threadedly connected to the inner wall of the baffle 15.

[0032] The movement of the baffle 15 is guided and supported by the guard plate 13, and the sliding position of the baffle 15 is adjusted by the lead screw 14.

[0033] Working principle: During material feeding, the stamped material is blocked by a pair of flexible bending plates 6 for storage. After a receiving and storage box is placed below the blanking plate 4, a certain weight of stamped parts is piled up on top of the flexible bending plates 6, causing the flexible bending plates 6 to deform under pressure and come into contact with the pressure sensor 8. The pressure sensor 8 sends an electrical signal to the controller 3, which then controls the electric telescopic rod 10 via PLC. The output end of the electric telescopic rod 10 drives the drive plate 12 to move. The drive plate 12 drives a pair of racks 11 to slide, causing a pair of gears 9 to reverse relative to each other. This causes the pair of flexible bending plates 6 to reverse relative to each other for material discharge. The material leaks out through the side not blocked by the baffle 15 for packaging. When it is necessary to adjust the angle of the blanking plate 4, simply insert the positioning pin 17 into the corresponding positioning hole 19 to adjust the angle of the blanking plate 4 and position it for better material discharge. The guide plate 5 can prevent parts from slipping off the blanking plate 4 and leaking during packaging.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
