Description
Technical field
This utility model relates to machine components processing, more specifically, relates to the dissection type forging mold of a kind of bucket tooth。
Background technology
Bucket tooth is the vitals on excavator, is similar to the tooth of people, belongs to consumable accessory。The processing technique of bucket tooth generally has casting or forging, and the bucket tooth mass ratio of forging casts, and therefore, it uses scope more and more extensive。Forging and molding refers to and metal is applied external force, metal is made to produce plastic deformation, change the shape and size of blank, and improve its interior tissue and mechanical property, obtain the blank of definite shape, size and performance or the shaping of part, the dependence substantially of traditional bucket tooth Forging Technology manually carries out, and there is a lot of deficiency
Slightly slip up during workman's blowing, substandard products will be caused；Carrying out flank of tooth intermediate frequency, complex process after the heat treatment quenching and tempering of bucket tooth, degree-of-difficulty factor is high, and the cycle is long, and production efficiency is very low。
On July 7th, 2015, we applied for the utility model patent of " processing method of a kind of bucket tooth ", and number of patent application is 2015103915261, and this utility model proposes the processing method of a kind of simple to operate, with short production cycle, bucket tooth that production efficiency is high。The method is as follows:
1, after choosing blank after metal material, heating, put between the upper die and lower die on friction press, upper die and lower die are carried out matched moulds punch die and obtains bucket tooth blank；Then adopt punch press that bucket tooth blank is carried out trimming；
2, bucket tooth blank is put between the upper die and lower die on friction press, upper die and lower die are carried out matched moulds punch die and obtains bucket tooth profiled member；
3, with punch press, bucket tooth profiled member is carried out trimming, punching, correction；Last oil cooling, quenching。
The processing method of bucket tooth that this utility model provides, eliminates machining processes, directly forges finished product, unitary mould ensure the processing of workpiece, with short production cycle, production efficiency is high。The hardness of the product obtained is higher, and percent defective is lower。
In production practices, it has been found that above-mentioned patented method yet suffers from following deficiency when forging: 1, integrally forming mould die cavity is relatively deep, and forming surface is narrower, abrasion severity in mould sideline in forging process, it is easy to produce fatigue crack。Mold repair difficulty, the process-cycle is long, costly。2, mould uses the time short, often forging about 100 needs to pull down mould, and by the mould on both sides again spot welding to reduce the gap between mould, gap is once more than 0.3mm, in forging process, metal will enter die gap, causes forging cannot take out smoothly from die cavity。
Summary of the invention
In order to overcome mould produced problem in above-mentioned forging process, the utility model proposes the dissection type forging mold of a kind of bucket tooth。
The dissection type forging method of this bucket tooth, it is characterised in that whole bucket tooth is divided into two parts blank, matched moulds punch die is carried out in a mold respectively after being heated by metal material after blank, forging and stamping become two bucket tooth blanks, are welded together by two blanks, finally carry out heat treatment。
The dissection type forging mold of this bucket tooth, is divided into two parts by bucket tooth, it is characterised in that the mould of every part includes the upper die and lower die matched, and the inner chamber constituted after upper die and lower die matched moulds is consistent with two parts shape of bucket tooth respectively。
Whole bucket tooth is divided into the method that two parts forge and press respectively, it is possible to the longitudinally wide plane of symmetry along bucket tooth is cut, longitudinal narrow plane of symmetry is cut or is perpendicular to major axis and cuts。
The dissection type forging method of this bucket tooth specifically includes following steps:
(1) metal material is selected；
(2) two metal forging blanks under；
(3) two metal forging blanks of step (2) are heated respectively；
(4) two metal forging blanks after step (3) being heated are respectively put between the upper die and lower die on forcing press, upper die and lower die are carried out matched moulds forging and stamping, obtains two half of bucket tooth blanks；
(5) two half of bucket tooth blanks of temperature of still having a surplus are carried out trimming, punching, correction；
(6) by two bucket tooth blank welding position finished edges of step (5), and it is welded into an overall bucket tooth；
(7) water-cooled after the bucket tooth of step (6) being heated；Obtain case hardness and the depth of hardening zone of designing requirement。
The utility model has the advantages that: whole bucket tooth is divided into two parts molding, and mold cavity is shallower, and forming surface is wider, in forging process, the abrasion of mould sideline is relatively light, and mold repair is easy, and the production cycle is long, and expense is low。Metal in forging process will not enter die gap, and forging can take out smoothly from mould, and production efficiency is high。
