Description
Technical field
The present invention relates to mold, specifically a kind of same bore different pressures triple-valve body universal mold and manufacturing process.
Background technique
Currently, triple-valve body forging mostly uses the manufacturing process of multi-ram forging, product shaping is high-quality, qualification rate and life
It is all higher to produce efficiency.But for the series of products of same bore specification different pressures rank, have the shortcomings that die cost is high.Together
The shape and size of the triple-valve body of one bore specification different pressures rank are consistent, the difference is that height, the level of vertical neck
The length and its diameter of bore of neck, with the other increase of pressure stage, the length of vertical neck height and horizontal neck increases, water
The diameter of bore of flat neck reduces, because multi-ram forging manufacturing process is accurate closed-die forging, mold cavity and the triple valve bodily form
Shape is consistent, so its mold of the triple-valve body of same bore different pressures is also different, the especially biggish triple valve of bore
Body, demand is smaller, each pressure rank may only need tens even several, and die size is big, and die cost improves
The production cost of triple-valve body.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of same bore different pressures triple-valve body universal mold and at
Shape method reduces die cost, increases economic efficiency.
The technical solution used to solve the technical problems of the present invention is that:
A kind of same bore different pressures triple-valve body universal mold, including upper mold are specific, the lower mold specifically cooperated with upper mold
Body, upper punch are placed in vertical neck neck bore, and left formed punch is placed in left horizontal neck neck bore, and right formed punch is placed in right horizontal neck neck bore,
Vertical neck neck bore is shoulder hole structure, and the upper top for adjusting ring and being placed in vertical neck neck bore, upper punch passes through upper adjusting ring；Left level
Neck neck bore and right horizontal neck neck bore are respectively shoulder hole structure, the left left side for adjusting ring and being placed in left horizontal neck neck bore, right adjusting ring
It is placed in the right side of right horizontal neck neck bore, left formed punch, right formed punch are each passed through left adjusting ring, right adjusting ring, left adjusting ring and right tune
Boss structure is respectively equipped on the inside of section ring.
The manufacturing process of above-mentioned same bore different pressures triple-valve body universal mold carries out as follows:
A, installation mold: upper mold is specifically connect with the dynamic beam of multi-cored forging press, and upper punch is vertical with multi-cored forging press to perforate
Cylinder connection, left formed punch, right formed punch are connect with multi-cored forging press horizontal cylinder respectively；
B, mold preheating and blank heating: pole blank and mold are preheated.
C, forge: blank is immediately placed in the specific type chamber of lower die after coming out of the stove, and upper mold specifically comes downwards to closes with lower mold
Mould and pressure maintaining, upper punch vertically descend eleven punch 11 position to terminal, the horizontal opposite position to terminal of perforating of most rear left formed punch, right formed punch
It sets, entire forging process terminates；
D, mold backhaul and take out forging: left formed punch and right formed punch, upper punch and upper mold successively multi-cored forging press horizontal cylinder,
Backhaul under vertical perforation cylinder and dynamic beam action, lower angled slide block under the action of lower liftout tank on be about to forging ejection, by forging
It takes out.
The present invention by adopting the above technical scheme, compared with prior art, beneficial effect is:
Die cost is greatly reduced, reduces mold manufacturing time, simplifies mold installation, improves efficiency, increase economic efficiency.
Further, prioritization scheme of the invention is:
The upper lower surface for adjusting ring is planar structure.
