Description

A kind of Forging Technology of low impurity steel cutter
Technical field
The present invention relates to cutter Forging Technology technical field, specially a kind of Forging Technology of low impurity steel cutter.
Background technique
Forging and stamping are that forging and punching press are collectively referred to as, be using the tup of metal forming machinery, anvil block, formed punch or by mold to blank Apply pressure, be allowed to generate plastic deformation, thus the forming and machining method of the product of shape and size needed for obtaining.
In forging processing, blank integrally occurs significantly to be plastically deformed, and has larger amount of Plastic Flow;In punch process In, blank is mainly shaped by changing the spatial position of each site area, inside do not occur the Plastic Flow of relatively large distance. Forging and stamping be mainly used for process metallic article, it can also be used to process it is certain nonmetallic, as engineering plastics, rubber, ceramic blank, adobe with And forming of composite material etc..
Rolling, draw etc. in forging and stamping and metallurgical industry belong to plastic processing or pressure processing, but forge and press main use In production metallic article, and roll, draw etc. is mainly for the production of the versatilities metal such as plate, band, tubing, profile and wire rod Material.Forging and stamping are that forging and punching press are collectively referred to as, just like industry and trade, also referred to as industry and trade.
With the progress of human civilization, bronze knife, iron knife, steel knife, stainless steel knife, the even Stupalox of minority, these Guarded blade utility knife is appeared in successively in the kitchen of the mankind, is increasingly evolved into simultaneous with the development of diet culture from simple cooking tools Tool uses the household items with artistic value.The classification of kitchen knife and function also increasingly refine, seize state power from a kitchen knife when In generation, develops into today in the special knife dedicated gang tool epoch.
In general, mainly there are three big kitchen knife systems, 1 Chinese style kitchen knife in the world;2 Western kitchen knifes;3 Japanese kitchen knifes.Material one As use stainless steel, at present there are also Stupalox, but Stupalox fear of throwing, therefore main product is still stainless steel.
In process of production, in order to be particular about speed, the cutter impurity produced is more for many cutters at present, purity compared with It is low, the hardness of cutter is seriously affected, to affect cutting-tool's used life, it would therefore be highly desirable to which a kind of improved technology solves Certainly this problem in the presence of the prior art.
Summary of the invention
The purpose of the present invention is to provide a kind of Forging Technologies of low impurity steel cutter, are forged by duplicate multiple hammer It beats, then cooperates borax, internal impurity can be forged out, then rotated by splash bar, the impurity of cast-internal can also separate Out, casting is made into molding finally by small-sized hammer type forging machine, the cutter ingredient which creates is purer, Impurity is less, can create equal cutters, to solve the problems mentioned in the above background technology.
To achieve the above object, the invention provides the following technical scheme: a kind of Forging Technology of low impurity steel cutter, packet Include following steps:
Step 1: according to drawing, steel material is selected;
Step 2: steel material is put into heating furnace, and temperature rapid increase by general to 1400 ~ 1600 DEG C, makes its fast heating, to original When material temperature degree rises to 1100 ~ 1200 DEG C, take out rapidly;
Step 3: forging equipment using large size and forged, casting is placed on and is forged on platform, from rear to preceding, forge, to The distance of preceding one hammer of movement, until one whole face of forging is all forged to then moving back, be rotated by 90 ° by forging, again from rear It forges forward, until the face is also all forged to repetition 3 ~ 5 times;
Step 4: forging is taken out, and four faces of forging are sprinkled borax, repeat step 3 by cooling, heating;
Step 5: 3 ~ 5 step 4 are repeated;
Step 6: after cooling, heating, borax is sprinkled, forging lower end is fixed by clamp tool, splash bar is fixed on forging top End, rotates clockwise 5 ~ 10 times, repeats step 3;
Step 7: it is repeated once step 6;
Step 8: cooling, heating forges equipment using small-sized, forging is got drawing shape;
Step 9: casting is completed the subsequent techniques such as to be ground, polished after being heat-treated.
Preferably, it is a kind of large-scale hammer type forging machine that the large size of the step 3, which forges equipment,.
Preferably, described Step 4: Step 6: being cooled to the mode of sand cooling in step 8.
Preferably, the middle-size and small-size hammer that forges of the step 8 is a kind of small-sized hammer type forging machine.
Preferably, splash bar includes fixing buckle and hand stick in the step 6, and the fixing buckle is rectangle, the fixing buckle two End is respectively arranged with hand stick.
Compared with prior art, the beneficial effects of the present invention are:
It is forged by duplicate multiple hammer, then cooperates borax, internal impurity can be forged out, then revolved by splash bar Turn, the impurity of cast-internal can also be separated, and casting is made molding, the forging and stamping side finally by small-sized hammer type forging machine The cutter ingredient that formula is created is purer, and impurity is less, can create equal cutters.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is splash bar structural schematic diagram.
