Abstract
The utility model discloses a blank-making mold for a creeper tread. The blank-making mold for the creeper tread comprises an upper mold and a lower mold, wherein the upper mold and the lower mold are both provided with cavities, the shape of the cavity formed by combining the upper mold and the lower mold is the same as the shape of the creeper tread, the upper mold and the lower mold are horizontally placed after being combined, and resistance ribs are arranged at bin portions of the upper mold and the lower mold. The blank-making mold for the creeper tread has the advantages that due to the fact that the upper mold and the lower mold are placed horizontally after being combined, namely a horizontal blank-making method is adopted, wrinkles are not produced, the procedure of repairing and grinding fissures is eliminated, the production cost is lowered, and the delivery circle is shortened. Due to the arrangement of the resistance ribs, deformation is reduced in the process of punching, the creeper tread is capable of fully contacting running wheels of a coal cutter, the service lives of the creeper tread and the coal cutter are prolonged, the service life of the blank-making mold is prolonged, and the production cost is indirectly lowered. After the service life is prolonged, the sale cost is lowered, and the damage rate of quality-guaranteeing money is lowered.
Description
Technical field
The utility model belongs to the creeper tread mould for forging, relates in particular to a kind of creeper tread mould.
Background technology
Because the domestic manufacturer of production creeper tread is less, what produce the creeper tread forging is few at present.The creeper tread raw material are round steel, and existing creeper tread forging has folding, crackle and burr, and is not attractive in appearance, and impact is used.Yield rate is low, the waste raw material.The creeper tread blanking mold adopts vertical base at present, owing to being entity around the creeper tread, middle porose, cause the cross section contrast too large, bring certain difficulty for the flowing forming of metal, vertical longitudinal cross-section cross from, go out a hole from the heavy in section, have following drawback: 1) drift hardness is had higher requirement; 2) changes of section is excessive, and metal fluidity is relatively poor, easily produces fold; 3) drift of same hardness, vertical base is more easy to wear, because drift and patrix are connected as a single entity, causes shortening of whole patrix life-span, and this has just increased the die cost accounting.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency a kind of creeper tread blanking mold is provided, and not only presentation quality is high for the creeper tread forging that this mould is produced, and has reduced also that forging is folding, crackle, has gone out the forging defects such as not enough.
For achieving the above object, the utility model is by the following technical solutions:
A kind of creeper tread blanking mold, comprise upper die and lower die, be provided with die cavity at mould and counterdie, the shape of die cavity is identical with the creeper tread shape behind the upper die and lower die matched moulds, horizontal positioned behind the upper die and lower die matched moulds, section is provided with the resistance rib in upper die and lower die die cavity storehouse.
Above-mentioned creeper tread blanking mold, described patrix is die, counterdie is punch.
Adopt technique scheme, the utility model has following advantage: because horizontal positioned behind the upper die and lower die matched moulds namely adopts the flat base, can not produce fold, save the operation of repairing the polishing crackle, reduced production cost, shortened the delivery cycle, because the setting of resistance rib, reduce distortion during punching, creeper tread is fully contacted with the road wheel of coal-winning machine, improved simultaneously both service life, prolong simultaneously the life-span of blanking mold, in a disguised form reduced production cost.Reduced our after cost after prolonging service life, improved to a certain extent company, also reduced to a certain extent the loss percentage of our quality guarantee gold at other.

The specific embodiment
A kind of creeper tread blanking mold as depicted in figs. 1 and 2, comprise patrix 1 and counterdie 3, be provided with die cavity 2 at mould 1 and counterdie 3, the shape of die cavity is identical with the creeper tread shape behind the upper die and lower die matched moulds, horizontal positioned behind the upper die and lower die matched moulds, namely adopt the flat base, section is provided with resistance rib 4,5 in upper die and lower die die cavity storehouse, and namely patrix is provided with resistance rib 4, is provided with lower resistance rib 5 on the counterdie, patrix of the present utility model is die, and counterdie is punch.
