When the workpiece to be processed is placed in the front burr removal cavity 14 and the back burr removal cavity 15, the mold closing and stamping is completed when the stripper plate 6 contacts the blanking plate 7; in this technical solution, the stripper plate 6 and the blanking plate 7 can be replaced according to the needs of the staff, and then different specifications of the front burr removal cavity 14 and the back burr removal cavity 15 are used, which is convenient for processing hardware components of different specifications.

[0025] A movable float 18 is embedded in the front deburring cavity 14, and a slidable punch 17 is embedded in the back deburring cavity 15. Springs 11 are respectively provided at the other ends of the punch 17 and the float 18. When the mold is opened, the spring 11 is compressed and pressurizes the punch 17 and the float 18 to demold the workpiece.

[0026] Specifically, an upper cover 1 is fixedly provided on the upper surface of the upper die base 2, an upper clamping plate 4 is horizontally provided below the upper die base 2, a stripping plate 5 is provided on the upper surface of the stripping plate 6, and pressure is applied to the stripping plate 5 when the upper clamping plate 4 is displaced, an upper pad 3 is fixedly provided on the upper surface of the upper clamping plate 4, and the other end of the upper pad 3 is in contact with the bottom surface of the upper die base 2; a lower pad 8 is provided on the bottom surface of the stripping plate 7, and the lower pad 8 is fixed on the upper surface of the lower die base 9. In this embodiment, the above-mentioned components maintain structural stability.

[0027] Specifically, the bottom surfaces of the stripping plate 6 and the blanking plate 7 are evenly distributed with template positioning pins 12. The stripping plate 6 is connected to the stripping backing plate 5 through the template positioning pins 12, and the blanking plate 7 is connected to the lower pad 8 through the template positioning pins 12. In this embodiment, the template positioning pins 12 make it easier for the staff to position the equipment.

[0028] Specifically, a plurality of bolts 13 are embedded on the upper surface of the blanking plate 7, and the other ends of the bolts 13 pass through the blanking plate 7 and are connected to the lower pad 8. In this embodiment, the blanking plate 7 and the lower pad 8 are kept stable in this way.

[0029] Specifically, a lower clamping plate 20 is embedded in the inner side of the blanking plate 7 in the front deburring cavity 14, and a stripping top plate 21 which can move up and down is provided on the upper surface of the lower clamping plate 20. A stripping spring 19 is provided at the bottom end of the lower clamping plate 20, and the top end of the stripping spring 19 passes through the lower clamping plate 20 and supports the stripping top plate 21. In this embodiment, the stripping spring 19 is arranged at the outer edge of the bottom end of the cavity.

[0030] Specifically, a detection device 16 is fixedly provided on the upper surface of the lower mold base 9 on the outer side of the blanking plate 7 and the lower pad 8. The detection device 16 is used to detect the demolding condition. In this embodiment, the detection device 16 adopts the photoelectric detection equipment commonly used in the prior art.

[0031] The working principle and use process of the utility model: In the utility model, during the use of the single punch die, the distance between the upper die base 2 and the lower die base 9 is changed to keep the stripper plate 6 and the blanking plate 7 open or closed. During this process, the guide column 10 serves as a guiding structure to keep the stripper plate 6 and the blanking plate 7 in parallel displacement during movement. The staff puts the hardware parts to be processed into the front deburring cavity 14 and the back deburring cavity 15. The mold closes the mold through the pressure of an external pressure pump. During the closing process, the upper clamping plate 4 and the stripper plate 6 act as the upper punching plates to apply pressure to the hardware parts to be processed, and the lower clamping plate 20 and the stripper top plate 21 act as the lower punching plates to apply pressure to the hardware parts to be processed. During this process, the mold pressurizes and removes the burrs on the outer ring of the hardware parts to keep the outer ring of the hardware parts smooth.

[0032] After the mold has finished stamping the hardware components, the mold opens. At this time, the stripping spring 19 can apply pressure to the stripping top plate 21 through its own elastic force, so that the components are pushed out from the cavity on the blanking plate 7. When the stripping plate 6 is raised to a higher height, the spring 11 presses the punch 17 so that the punch 17 pushes the components out. In this way, the hardware components can be effectively prevented from being stuck inside the mold, which facilitates the continuous processing and production of hardware components and effectively improves production efficiency.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to be a further limitation of the present invention. All equivalent changes made using the contents of the present invention specification and drawings are within the scope of protection of the present invention.
