Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
A blanking punch comprises a punch body 1 and a hanging platform structure formed on the top of the punch body 1, wherein the hanging platform structure is an inclined plane hanging platform 2 protruding out of the side wall of the punch body 1.
The side inclined plane of the inclined plane hanging table 2 is an interaction surface between the blanking punch and the die plate, and for the plane hanging table structure, the area of the interaction surface is greatly improved by the hanging table of the inclined plane structure in the embodiment, so that the reaction force is uniformly dispersed to act on the side inclined plane, and the service life of the blanking punch is prolonged.
The hanging platform structure and the punch body are integrally formed, and the processing, the popularization and the application are convenient.
The punch comprises a punch body and is characterized by comprising a square cylindrical body, wherein the front side surface of an inclined surface hanging table is aligned with the front side surface of the punch body, the top surface of the inclined surface hanging table is aligned with the top surface of the punch body, and the rear side surface of the inclined surface hanging table is aligned with the rear side surface of the punch body.
Example 2
The size of the punching punch is optimized on the basis of the embodiment 1, and the inclination a of the inclined hanging platform is 3-7 degrees, and preferably 5 degrees. The width b of the inclined plane hanging table is 0.5-1.0mm, preferably 0.8mm, and the height c of the inclined plane hanging table is 5-10mm, preferably 8 mm. Experiments prove that under the inclination and the size, the assembly of the blanking punch is facilitated, and the service life of the blanking punch can be prolonged.
Furthermore, the height of the hanging table is one fourth to one sixth of the height of the blanking punch.
