Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically to an automatic waste removal device for stamping dies. Background Technology

[0002] Punching is a common machining process. Currently, in the production of some punched parts, due to the limitations of machine tools and mold structures, the stamping waste cannot be automatically discharged after punching. Workers have to manually clean up the waste. Cleaning up the waste requires the punch press to be stopped, resulting in low production efficiency. Furthermore, due to the possibility of omissions in manual waste cleaning, the waste is not cleaned up in time and accumulates in the mold, which can crack the mold. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic waste removal device for stamping dies.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic waste removal device for stamping dies, comprising a processing table, a bottom die at the upper end of the processing table, a first lifting component fixedly disposed above the bottom die, and a top die at the output end of the first lifting component, a discharge component at the upper end of the processing table, the discharge component comprising a second lifting component, a movable seat, and a slide groove, a support plate fixedly disposed on one side of the second lifting component, a slider slidingly engaging with the slide groove at the lower end of the support plate, the movable seat fixedly disposed at the output end of the second lifting component, and multiple electromagnets at the lower end of the movable seat, a fixed frame fixedly disposed at the lower end of the processing table, a rotating shaft rotatably disposed on the fixed frame, two screws with positive and negative thread structures symmetrically disposed on the rotating shaft, the screws penetrating the slider, and a motor fixedly disposed on one side of the fixed frame, the output end of the motor being connected to one end of the rotating shaft.

[0007] Furthermore, an improvement of this utility model is that two material discharge components are symmetrically arranged on the upper bottom mold of the processing table.

[0008] Furthermore, the improvements of this utility model include that the first lifting component adopts a hydraulic cylinder, and the second lifting component adopts a telescopic cylinder.

[0009] Furthermore, an improvement of this utility model is that the motor is a servo motor.

[0010] To facilitate waste collection, the present invention includes an improvement where two receiving components are symmetrically arranged on the bottom mold of the processing table.

[0011] Furthermore, the present invention includes improvements such as the receiving assembly comprising an empty trough and a storage box, the inner wall of the empty trough being provided with a guide groove, and the top of the storage box being symmetrically provided with two guide rails that slide in cooperation with the guide groove.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides an automatic waste removal device for stamping dies, which has the following beneficial effects:

[0014] Starting the motor allows the support plate to move the second lifting assembly above the bottom mold. Activating the second lifting assembly lowers the moving seat, causing the electromagnet to generate magnetic attraction, which attracts the scrap metal sheet from the bottom mold to the lower end of the moving seat. Finally, the support plate moves the second lifting assembly to both sides of the bottom mold. De-energizing the electromagnet allows the scrap to fall to both sides of the bottom mold, facilitating the removal of scrap metal sheet from the bottom mold. This process eliminates the need for manual cleaning of the scrap on the bottom mold, ensuring the processing efficiency of this structure. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-3This utility model discloses an automatic waste removal device for stamping dies, comprising a processing table 1, a bottom die 2 at the upper end of the processing table 1, a first lifting component 4 fixedly arranged above the bottom die 2, and a top die 3 at the output end of the first lifting component 4, a discharge component at the upper end of the processing table 1, the discharge component including a second lifting component 5, a movable seat 6 and a slide groove 9, a support plate 8 fixedly arranged on one side of the second lifting component 5, a slider 10 slidably engaged with the slide groove 9 at the lower end of the support plate 8, the movable seat 6 fixedly arranged at the output end of the second lifting component 5, and multiple electromagnets 7 at the lower end of the movable seat 6, a fixed frame 11 fixedly arranged at the lower end of the processing table 1, a rotating shaft 13 rotatably arranged on the fixed frame 11, two screws 14 with positive and negative tooth structures symmetrically arranged on the rotating shaft 13, the screws 14 being able to penetrate the slider 10, and a motor 12 fixedly arranged on one side of the fixed frame 11, the output end of the motor 12 being provided with a drive shaft connected to one end of the rotating shaft 13;

[0021] In use, when the sheet metal workpiece to be stamped is placed on the bottom mold 2, activating the first lifting assembly 4 allows the top mold 3 to stamp the workpiece. After stamping, the remaining scrap metal (steel or iron) remains on the bottom mold 2. At this point, activating the motor 12 causes the rotating shaft 13 to drive the screw 14 to rotate. Through the threaded engagement, the slider 10 slides along the screw 14, thereby moving the support plate 8 above the bottom mold 2, driven by the second lifting assembly 5. Further activation of the second lifting assembly 5 lowers the moving seat 6. The process involves lowering the mold and energizing the electromagnet 7, which then generates a magnetic force that attracts the scrap metal sheet on the bottom mold 2 to the lower end of the moving seat 6. The second lifting assembly 5 then raises the moving seat 6, and finally, the support plate 8 moves the second lifting assembly 5 to both sides of the bottom mold 2. The electromagnet 7 is then de-energized, losing its magnetic force and allowing the scrap metal sheet to fall to both sides of the bottom mold 2, facilitating the discharge of the scrap metal sheet on the bottom mold 2. This process eliminates the need for manual cleaning of the scrap metal on the bottom mold 2, ensuring the processing efficiency of this structure.

[0022] In this embodiment, two material discharge components are provided on the symmetrical bottom mold 2 at the upper end of the processing table 1.

[0023] In this embodiment, the first lifting component 4 is a hydraulic cylinder, the second lifting component 5 is a telescopic cylinder, and the motor 12 is a servo motor.

[0024] In this embodiment, two receiving components are symmetrically arranged on the bottom mold 2 of the processing table 1. The receiving components include an empty groove 15 and a storage box 16. The inner wall of the empty groove 15 is provided with a guide groove. The top of the storage box 16 is symmetrically provided with two guide rails that slide in cooperation with the guide groove. The storage box 16 can collect the cleaned waste material. When it is necessary to process the waste material in the storage box 16, the storage box 16 can be pulled out from the empty groove 15. The structure is simple and the operation is convenient.
