[0001] This utility model relates to the field of stamping equipment technology, specifically to a stamping press with a cleaning device. Background Technology

[0002] Stamping presses are core equipment in the field of metal cold working. They are mainly used for the batch forming of metal workpieces. Stamping presses take stamping dies as their core and output pressure through hydraulic or mechanical transmission systems to apply external force to raw materials such as metal sheets and coils, thereby completing processes such as blanking, bending, stretching, and forming to obtain workpieces that meet specifications. They have a wide range of applications, covering industries such as automobiles (body parts), electronics, home appliances, and hardware.

[0003] However, existing stamping presses lack an automatic cleaning mechanism. The stamping waste remaining in the slots must be cleaned manually using tools such as brushes and scrapers. The machine must be stopped during cleaning (to avoid operators coming into contact with moving parts). Manual cleaning is not only labor-intensive, but also prone to waste accumulation due to incomplete cleaning, which affects the stamping accuracy of subsequent workpieces. Frequent machine stops for cleaning will interrupt the continuous stamping process and significantly reduce production efficiency. Utility Model Content

[0015] 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.

[0016] Please see Figures 1-3 An embodiment of this utility model provides a stamping press with a cleaning device, including: an operating table 1.

[0017] Among them, such as Figure 1As shown, an upper support 2 is installed on the top of the operating table 1, a hydraulic cylinder 3 is installed on the upper support 2, a stamping block 5 is installed on the piston rod of the hydraulic cylinder 3, and a support plate 6 is detachably installed on the top of the operating table 1 via an mounting plate 7. The support plate 6 is provided with a punching groove 16. When the stamping press is in operation, the piston rod of the hydraulic cylinder 3 drives the stamping block 5 to move up and down to perform stamping processing on the workpiece placed in the punching groove 16 of the support plate 6.

[0018] Furthermore, the top of the mounting plate 7 is provided with multiple equally spaced sliding grooves 4, and the bottom of the support plate 6 is slidably mounted on the sliding grooves 4. The sliding grooves 4 provide a sliding connection track for the support plate 6, so that the support plate 6 can move along the sliding grooves 4 during installation or disassembly, and the installation position can be selected according to the different positions of the sliding grooves 4.

[0019] In this embodiment, as Figure 1 As shown, both sides of the inner wall of the trough 16 are provided with water inlet holes 17. Two water pumps 14 are symmetrically installed at the bottom of the support plate 6. The water inlets of the two water pumps 14 are connected to a three-way pipe 12. The water outlet of the water pump 14 is connected to the water inlet hole 17. A push switch 15 is installed on the top of the support plate 6. The push switch 15 is electrically connected to the water pump 14.

[0020] The support plate 6 can be detachably installed on the top of the operating table 1 via the mounting plate 7, making it easy to replace according to the workpiece requirements. The cleaning function is triggered by the stamping block 5 touching the press switch 15 downwards, which starts the water pump 14. The water source is delivered through the three-way pipe 12 and the outlet of the water pump 14 to the water inlet holes 17 on both sides of the inner wall of the punch groove 16, and sprayed out from the water inlet holes 17 to wash away the stamping waste remaining in the punch groove 16. This allows the stamping press to automatically start flushing during the stamping gap, which can not only quickly cool the workpiece but also achieve non-stop flushing operation.

[0021] Furthermore, a water tank 13 is installed inside the control panel 1. One end of the bottom of the three-way pipe 12 passes through the water tank 13. The water tank 13 can store cleaning water and provide a stable water source for the water pump 14 without the need for external water pipes.

[0022] It should be noted that the cross-section of the stamping block 5 is T-shaped, and the top area of ​​the T-shaped cross-section is relatively large, which allows it to contact the push switch 15 during the descent.

[0023] In another embodiment, such as Figure 1 As shown, an air pump 9 is installed on one side of the operating table 1. The air outlet of the air pump 9 is connected to a corrugated hose 10. One end of the corrugated hose 10 is connected to a spray gun 11. The air pump 9 generates a high-pressure airflow, which is delivered to the spray gun 11 through the corrugated hose 10. The spray gun 11 can spray the high-pressure airflow in a direction to dry the residual water in the flushing tank 16 after rinsing, or to blow away small stamping waste that is difficult to remove by water washing.

[0024] Furthermore, a clamp 8 is installed on the outer wall of the upper support 2, and the spray gun 11 passes through the clamp 8. The clamp 8 can fix the spray gun 11 to the outer wall of the upper support 2, so as to prevent the spray gun 11 from being placed randomly during the stamping operation, resulting in loss or damage.

[0025] Based on the above technical solution, the working steps of this solution are summarized as follows: When the stamping press is in operation, the piston rod of the hydraulic cylinder 3 drives the stamping block 5 to move up and down, and performs stamping processing on the workpiece placed in the punching groove 16 of the support plate 6.

[0026] The support plate 6 is detachably mounted on the top of the operating table 1 via the mounting plate 7, making it easy to replace according to the workpiece requirements. The cleaning function is triggered by the stamping block 5 touching the press switch 15 downwards, which starts the water pump 14. The water source is delivered through the three-way pipe 12 and the outlet of the water pump 14 to the water inlet holes 17 on both sides of the inner wall of the punch groove 16, and sprayed out from the water inlet holes 17 to wash away the stamping waste remaining in the punch groove 16. This allows the stamping press to automatically start flushing during the stamping gap, which can not only quickly cool the workpiece but also achieve non-stop flushing operation.

[0027] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
