[0002] The punching needle is an extremely important punching component of the mold. During the mold closing and punching process, the existing punching needle relies on the punching needle to continue to move downward to push the material to separate it from the mother material. In order to ensure complete separation, the continued downward stroke is generally large. This method has a slow unloading speed and a low initial speed during the unloading process. There is a probability that the material will deviate and get stuck in the mold during the unloading process, affecting the normal unloading of the material. Summary of the invention

By arranging an elastically retractable pushing needle in the punching needle, the cut material sheets can be quickly separated from the mother material by pushing during the punching operation, thereby achieving the purpose of rapid material feeding, avoiding material sheet jamming, and improving material feeding efficiency.
[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a fast blanking punch needle structure, including a punch needle body, the top of the punch needle body is a punch needle mounting part, and the bottom of the punch needle body is a punching blade; the punch needle body is an axially through hollow structure, in which a push needle is elastically arranged in the cavity through an axial elastic part, and the push needle is arranged to shuttle in and out of the punching blade.
[0005] Furthermore, the push needle is provided with an elastic thrust by the axial elastic member so that its pushing end is in a state of extending out of the punching blade, and when the push needle moves downward with the punch needle body and encounters material obstruction, the push needle overcomes the elastic thrust by the resistance it encounters and compresses the axial elastic member into the punching blade.
[0006] Furthermore, a threaded plug is connected to the top of the axial elastic part, and the hollow cavity is composed of an installation cavity section, a threaded cavity section, an elastic part cavity body and a push pin cavity section whose radial dimensions gradually decrease from top to bottom. The threaded plug is arranged corresponding to the installation cavity section and the threaded cavity section, the axial elastic part is arranged corresponding to the elastic part cavity body, and the push pin is arranged corresponding to the push pin cavity section.
[0007] Furthermore, a piston is connected between the axial elastic member and the push needle, and the piston is axially slidably arranged in the cavity of the elastic member.
[0008] Furthermore, an upper pressure balance hole and a lower pressure balance hole connected to the elastic component cavity are provided on the punch needle body, the upper pressure balance hole is maintained at a position between the threaded plug and the piston, and the lower pressure balance hole is connected to the bottom of the elastic component cavity.
[0009] Furthermore, the pushing end of the pushing needle is a dome structure, or a rounded structure with rounded edges.
[0010] Beneficial effect: The utility model arranges an elastically retractable pushing needle in the punching needle, which can quickly separate the cut sheet from the mother material by pushing during the punching operation. When pushing the sheet, the sheet is given a faster initial velocity, shortening the sheet feeding time and greatly reducing the degree and probability of the sheet feeding deviation, thereby achieving the purpose of fast feeding, avoiding sheet jamming and improving feeding efficiency.

[0014] The utility model is further described below in conjunction with the accompanying drawings.
[0015] As attached Figure 1 , Attachment Figure 2 And attached Figure 3 As shown, a punching needle structure for rapid material removal includes a punching needle body 1, the top of the punching needle body 1 is a punching needle mounting portion 2, and the bottom of the punching needle body 1 is a punching blade 3; the punching needle body 1 is an axially through hollow structure, in which a pusher needle 5 is elastically arranged in the cavity 10 through an axial elastic member 4, and the pusher needle 5 is arranged to shuttle in and out of the punching blade 3. More specifically, the pusher needle 5 is provided with a spring thrust force provided by the axial elastic member 4 so that its pusher end is in a state of extending out of the punching blade 3, and the pusher needle 5 that moves downward with the punching needle body 1 is in a state of being blocked by the material, and the pusher needle 5 overcomes the spring thrust force through the resistance it encounters to compress the axial elastic member 4 and retract into the punching blade 3. The utility model arranges an elastically retractable pushing needle 5 in the punching needle, and can quickly separate the cut sheet from the mother material by pushing during the punching operation. When pushing the sheet, a faster initial velocity is given to the sheet, which shortens the sheet feeding time and greatly reduces the degree and probability of the sheet feeding deviation, thereby achieving the purpose of fast feeding, avoiding sheet jamming, and improving feeding efficiency.
[0016] In addition, since the push pin 5 is used to push the material out, the downward movement stroke of the punch body 1 will be shortened accordingly, and it can be reset only when the material is cut out.
[0017] As attached Figure 3As shown, the top of the axial elastic member 4 is connected with a threaded plug 6, and the hollow cavity 10 is composed of a mounting cavity section 10a, a threaded cavity section 10b, an elastic member cavity 10c, and a push pin cavity section 10d, the radial dimensions of which gradually decrease from top to bottom. The threaded plug 6 is arranged corresponding to the mounting cavity section 10a and the threaded cavity section 10b, the axial elastic member 4 is arranged corresponding to the elastic member cavity 10c, and the push pin 5 is arranged corresponding to the push pin cavity section 10d. In the present utility model, the threaded plug 6 is a hexagonal threaded plug, the threaded portion of the hexagonal threaded plug is screwed into the threaded cavity section 10b, and the plug head of the hexagonal threaded plug is hidden in the mounting cavity section 10a.
[0018] In order to limit the axial downward movement of the push pin 5 in the anti-slip cavity and also to limit the length of the push pin 5 extending out of the punching blade 3, in the present utility model, a piston 7 is connected between the axial elastic member 4 and the push pin 5, and the piston 7 is axially slidably arranged in the elastic member cavity 10c. The axial elastic member 4 is preferably a spring, and the two ends of the spring are respectively connected to the threaded portion of the hexagonal threaded plug and the piston 7.
[0019] As attached Figure 3 As shown, the punch body 1 is provided with an upper pressure balance hole 8 and a lower pressure balance hole 9 which are connected to the elastic member cavity 10c. The upper pressure balance hole 8 is maintained between the threaded plug 6 and the piston 7, and the lower pressure balance hole 9 is connected to the bottom of the elastic member cavity 10c. The upper pressure balance hole 8 and the lower pressure balance hole 9 are both for maintaining the internal and external pressure balance of the elastic member cavity 10c with the piston 7, so as to ensure the normal axial displacement of the push pin 5.
[0020] In order to avoid damaging the material sheet when pushing the material, the pushing end of the pushing needle 5 is a dome structure, or a rounded structure with rounded edges.
[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
