As shown in fig. 1, the gasket punch according to the embodiment of the present application includes an inner die 100, an outer die 200, and a fixing cap 300. The inner die 100 comprises a connecting part 110 and an inner punch head 120 which are fixedly connected, and the diameter of the inner punch head 120 is equal to the inner diameter of the sealing gasket to be prepared; the connecting part 110 is detachably connected with the fixing cover 300; the outer die 200 comprises a mounting part 210 and an outer punch 220 which are fixedly connected, the outer punch 220 is provided with a cavity 230, and the diameter of the outer punch 220 is equal to the outer diameter of the sealing gasket; the fixed cover 300 is detachably and fixedly connected with the mounting portion 210, the inner punch head 120 is located in the cavity 230, the center axes of the inner punch head 120 and the outer punch head 220 coincide, and one end of the inner punch head 120, which is far away from the connecting portion 110, is flush with one end of the outer punch head 220, which is far away from the mounting portion 210.

As will be appreciated by those skilled in the art, the gasket is generally annular in shape, so that a circular hole exists in the center of the gasket.

In the embodiment of the application, by arranging the inner punch 120 and the outer punch 220, the inner punch 120 is used for punching a circular hole in the center of the sealing gasket, and the outer punch 220 is used for punching the outer ring size of the sealing gasket.

In this embodiment, since the inner punch 120 and the outer punch 220 are integrally mounted through the fixing cap 300, the coaxiality of the central axes of the inner punch 120 and the outer punch 220 is ensured during the mounting process, i.e., the concentricity of the sealing pads can be ensured during punching. On the other hand, in the present embodiment, the outer die 200 and the inner die 100 are detachably and fixedly connected through the fixing cover 300, so that when gaskets of different sizes are required, only the outer die 200 and the inner die 100 of different sizes need to be combined, and the application range of the embodiment of the present application is greatly increased.

In one embodiment, an end of the inner punch head 120 remote from the connecting portion 110 is provided with a chamfer. It can be understood by those skilled in the art that, during punching, one end of the inner punch head 120 far away from the connecting portion 110, i.e. the inner die edge 140 of the inner die 100, contacts with the material to be punched, and applies a force toward the material to be punched in the axial direction, so that the inner die edge 140 cuts the material to be punched. The cutting diameter a of the inner die blade 140 (i.e., the diameter of the inner punch) is equal to the diameter of the inner ring of the sealing pad.

In one embodiment, the inner punch head 120 defines an inner cavity 130, and the inner cavity 130 extends through an end of the inner punch head 120 remote from the connecting portion 110. With the arrangement, waste materials cut by the inner die blade 140 can enter the inner cavity 130, so that the cutting difficulty can be further reduced, and the required cutting force can be saved.

In one embodiment, one end of the outer punch 220 away from the mounting portion 210 is provided with a chamfer. As known to those skilled in the art, one end of the outer punch 220, which is away from the mounting portion 210, is an outer mold edge 240 of the outer punch 200, and similarly, the outer mold edge 240 is provided with a chamfer, which can increase the sharpness of the outer mold edge 240, so that the sealing ring can be conveniently punched out of the material to be punched. The cutting diameter b of the outer die edge 240 (i.e., the diameter of the outer punch) is equal to the diameter of the inner ring of the seal.

In one embodiment, the fixing cap 300 includes a fixing head 310 and a first fixing block 320, the first fixing block 320 is provided with a first fixing hole, a hole wall of the first fixing hole is provided with a first internal thread, and the connecting portion 110 is provided with a first external thread, so that the connecting portion 110 is detachably connected to the fixing cap 300 by the first internal thread and the first external thread. Through threaded connection, can make things convenient for the dismantlement of fixed lid 300 and interior die 100, screw thread processing only needs the frame worker to accomplish, and machine tooling can avoid spare part to warp in the course of working to can guarantee the size of interior die 100 and fixed lid 300, the axiality when further guaranteeing interior die 100 and the installation of outer die 200.

As shown in fig. 1, in an embodiment, an outer wall of the first fixing block 320 facing away from the hole wall is provided with a second external thread, and the mounting portion 210 is provided with a second internal thread, so that the fixing cover 300 is detachably connected to the mounting portion 210 by the second external thread matching with the second internal thread. By such an arrangement, the volume of the fixing cover 300 can be reduced, and materials can be saved.

The application also provides an embodiment, as shown in fig. 2, in this embodiment, the fixed cover 300 further includes a second fixed block 330, the second fixed block 330 with the fixed head 310 is connected, and is equipped with a second fixed hole, the first fixed block 320 is located in the second fixed hole, and with the pore wall interval of second fixed hole, be equipped with the second internal thread on the pore wall of second fixed hole, the through-hole has been seted up at the middle part of installation department 210, the perisporium of installation department 210 is equipped with the second external thread, the second internal thread with the cooperation of second external thread, so that the fixed cover 300 with the connection can be dismantled to installation department 210, the fixed head 310 is located in the through-hole.

In this embodiment, by forming two internal threads on the fixing cover 300, i.e., a first internal thread for fixing the inner punch 100 and a second internal thread for fixing the outer punch 200, and forming a through hole on the outer punch 200 to pass through the inner punch head 120, it is possible to process some small-sized gaskets or gaskets having a small diameter difference between the inner ring and the outer ring. Through set up the screw thread on first fixed block and second fixed block respectively, can increase the intensity of fixed lid for the punching press of less size sealed pad increases the application scope of this application embodiment.

In one embodiment, the material of the outer punch 200 and the material of the inner punch 100 are both high carbon steel. The high-carbon steel has high strength, and the service life of the inner punch die 100 and the outer punch die 200 improved in the embodiment of the application can be prolonged.
