Method for processing cutter blank of kitchen knife

Abstract

The invention discloses a machining method for a kitchen knife blank, which is characterized by consisting of following steps: selecting stainless steel hot rolling coils as raw materials; pulling thehot rolling coils to be straight belts by using a straightener, and cutting the straight belts transversely into straight blocks; punching the straight block by using a punching machine to form blanks; heating and forging blank brackets to make the blank brackets to be handle rudiments; heating the blanks at a high temperature; hot rolling the hyperthermia blanks by using a roller to produce primary blanks; slicing the primary blanks to form knife blanks; leveling and quenching knife blanks by using a leveling machine; and tempering the knife blanks by using a tempering furnace. The beneficial effects of the invention are: increasing the pass percent of knife blank processing, increasing machining quality of knife blanks, improving process velocity of knife blanks.

Description

technical field [0001] The invention belongs to the technical field of kitchen knife processing, and in particular relates to a processing method of a kitchen knife blank. Background technique [0002] In the prior art, the processing method of the kitchen knife blank is: at first, select the stainless steel hot-rolled coil as raw material and use the straightening machine that the hot-rolled coil is drawn into a straight strip, and the straight strip is transversely sheared with a shearing machine, and cut into straight strips. block; punch the straight block with a punching machine to form a blank, which is a rectangular steel plate with a lug at one end; secondly, use a belt hammer to forge the lug of the blank to make the lug form the prototype of the handle; and then heat the blank at high temperature ; Then use a belt hammer to forge the blade part of the high-temperature blank, and thin and widen the blank to form a blank; after that, use a punch to slice the blank ac...

AI Technical Summary

Problems solved by technology

However, when the belt hammer is used to forge the blade part of the high-temperature blank, the forging is uneven, the blade body of the blade is uneven due to forging, the blade body is curved, the scrap is high, the qualified rate of the blade is low, and the noise is high. The forging oil smoke is heavy, the pollution is large, the forging time of the knife body is long, and the machining speed of the knife blank is slow

[0003] The disadvantages of the prior art are: the knife body of the kitchen knife blank is uneven due to forging, the pass rate of the knife blank processing is low, the forging time of the knife body is long, and the processing speed of the knife blank is slow
