Abstract

The utility model relates to the field of machining, in particular to an extrusion and stretching forming die, which comprises a female die and a male die, wherein a forming gap is arranged between the female die and the male die, the size of a forming surface part with flatness requirements corresponding to a processing material is consistent with the thickness of the processing material, and the size of the forming surface part without flatness requirements corresponding to the forming gap is smaller than the thickness of the processing material. By arranging the forming gaps of the female die and the male die, when the extrusion operation is carried out on the part with the flatness requirement of the processed material, the material can not generate internal stress due to the fact that the forming gaps are consistent with the thickness of the material, the extruded part can have good flatness, and the compression deformation of the processed material in the extrusion process can be ensured aiming at the design that the forming gaps corresponding to other forming surface parts which do not need to have the flatness requirement are smaller than the thickness of the material.

Description

Extrusion stretching forming die Technical Field The utility model relates to the field of machining, in particular to an extrusion stretch forming die. Background Extrusion stretch forming dies are tools used to produce various metallic or non-metallic articles by extruding and stretching a billet into a desired shape and size. The mold plays a crucial role in manufacturing, and has wide application in the industries of automobile manufacturing, aerospace, electronics and the like. In the extrusion stretch forming process of the material, internal stress is formed inside the material due to extrusion, so that the situation of uneven flatness easily occurs on certain forming surfaces of the material. Disclosure of utility model The utility model aims to solve the technical problem of providing an extrusion and stretching forming die for ensuring the requirement of forming surfaces. In order to solve the technical problems, the extrusion and stretching forming die comprises a female die and a male die, wherein a forming gap is arranged between the female die and the male die, the size of a forming surface part with flatness requirements corresponding to a processing material is consistent with the thickness of the processing material, and the size of the forming surface part without flatness requirements corresponding to the forming gap is smaller than the thickness of the processing material. Further, the female die is rotatably arranged. Further, the male die is rotatably arranged. Further, the punch is uniformly divided along the circumferential direction to form a plurality of punch blocks, and each punch block is movable along the height direction of the punch. Further, the plurality of stamping blocks are moved away from the female die one by one. Further, the stamping die further comprises a driving structure, the driving structure comprises a pressing rod, the stamping blocks are provided with moving grooves extending along the height direction of the male die, one ends of the moving grooves, which are close to the female die, are positioned at the same height position, and the lengths of the moving grooves are sequentially increased according to the sequence that the corresponding stamping blocks are moved away from the female die one by one; the pressing rod is movably matched with the movable groove and drives the punching block to move along the height direction of the male die. Further, the compression bar is provided with a moving block matched with the corresponding moving groove of the punching block along the circumferential direction of the compression bar. Further, a spring is arranged at one end of the moving block, which is close to the moving groove and far away from the female die. Further, the tail end of the stamping block is provided with an oil filling hole communicated with the moving groove. Further, a sliding block is arranged on the side face of the stamping block, a sliding groove is arranged on the side face of the stamping block adjacent to the sliding block, and the sliding block is in movable fit with the sliding groove. The extrusion die has the advantages that the forming gaps of the female die and the male die are arranged, when extrusion operation is carried out on the part with the flatness requirement of the processed material, the formed gaps are consistent with the thickness of the material, the material can not generate internal stress, the extruded part can have good flatness, and the pressed deformation of the processed material in the extrusion process can be ensured aiming at the design that the forming gaps corresponding to the part of the forming surface without the flatness requirement are smaller than the thickness of the material.
