Punching die for producing hard alloy saw-tooth tool bit

Abstract

The invention relates to a punching die for producing a hard alloy saw-tooth tool bit, comprising a die body, an upper punch seat, a lower punch seat, an upper punch and a lower punch, wherein the upper punch and the lower punch are respectively installed on the upper punch seat and the lower punch seat, an upper fixing sheet and a lower fixing sheet are respectively arranged between the upper punch seat and the upper punch as well as between the lower punch seat and the lower punch; the upper punch is sleeved on the upper fixing sheet; the lower punch is sleeved on the lower fixing sheet; annular pad forks are also sleeved at two sides of the lower punch; the die body is placed on the upper end faces of the annular pad forks; a die cavity is formed by the upper end face of the lower punch and the die body; and the upper punch is correspondingly arranged above the die cavity. Because the annular pad forks, the upper fixing sheet and the lower fixing sheet are arranged, the punching die for producing the hard alloy saw-tooth tool bit has simple structure and is convenient for mounting and dismounting; when the punching die is produced, the damage to the lower punch, caused by stress concentrated on the lower punch, is avoided by means of the annular pad forks through stamping the upper punch and the lower punch in one step, and the stamping is stable, therefore, the production efficiency is greatly improved, the maintenance cost is saved, and the product quality is enhanced.

Description

technical field [0001] The invention relates to a stamping die, in particular to a stamping die for producing cemented carbide sawtooth cutter heads, and belongs to the technical field of mechanical tool manufacturing. Background technique [0002] The existing cutter head mold for the production of cemented carbide sawtooth cutter head, which uses the upper and lower punches of the press to stamp up and down at the same time to produce the cemented carbide sawtooth cutter head. Stability affects the quality of product processing, and the production efficiency is very low, which can easily cause damage to the lower punch and increase maintenance costs. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a stamping die for producing cemented carbide sawtooth cutter heads with stable stamping, simple structure, and convenient operation and disassembly. [0004] The present invention is ...
