Abstract
The invention belongs to the processing and manufacturing fields of forging mold, and in particular to a kind of glass of forging mold and punching head.In the contour forging technique of usual parts, need to prepare the integration mold suitable for forging, but when mold and punching head height and diameter ratio >=0.6, mold and punching head part is easily deformed in forging process, it is impossible to be forged qualified forging, be reduced die life.By the way that integration mold is changed to split punch, and each split punch is processed and manufactured respectively, then by the convexo-concave connection mode between split punch, most split punch connects into a unitary mould to the present invention at last；After split punch position distortions, it is only necessary to replace split position, die ontology is continuing with, and extends die ontology service life.
Description
Technical field
The invention belongs to the processing and manufacturing fields of forging mold, and in particular to a kind of glass of forging mold and punching head.
Background technology
In the contour forging technique of usual parts, need to prepare the integration mold suitable for forging.But when mold and punching head height
During with diameter ratio >=0.6, mold and punching head part is easily deformed in forging process, it is impossible to be forged qualified forging, be reduced
Die life.
Invention content
The technical problems to be solved by the invention are：Improve mold and punching head height and the cup forging of diameter ratio >=0.6
The structure of mold extends die life.
The technical scheme is that：In order to extend making for height of punch and the cup forging mold of diameter ratio >=0.6
Use the service life.Integration mold is changed to split punch by spy.Split punch has male connecting portion, and die ontology is connected with spill
Portion is processed and manufactures respectively to split punch and body mold, and passes through the convex-concave between split punch and die ontology
Most split punch connects into a unitary mould to connection mode with die ontology at last.It is convex between split punch and die ontology
Recessed connection is connected the side of contact by the way of vertical with die ontology, and is coordinated between the two using interference mode.
Convexo-concave connection mode between split punch and body mold is to carry out the die ontology with female connection portion
After heating, its concave portions is socketed on to the male portion of the split punch with male connecting portion, so as to complete the whole of mold
Body connects.
There is through-hole, for dismantling split punch among the die ontology.
The beneficial effects of the invention are as follows：By the way that integration mold is changed to split punch, and respectively to each split punch
It is processed and manufactures, then most split punch connects into a whole mould at last by the convexo-concave connection mode between split punch
Tool；After split punch position distortions, it is only necessary to replace split position, die ontology is continuing with, and is extended die ontology and is used
Service life.

Specific embodiment
Below by specific embodiments and the drawings, the present invention is further described in detail
The drum forging shaft of certain h type engine h uses GH4169 materials, and it is 5CrNiMo to select forging mold material.The forging
It is a kind of typical cup forging, forging bore depth has reached 0.8 with diameter ratio, in order to extend this glass of class forging part mold
Service life, the machining manufacture of forging mold using the present invention, by forging mold punch split production, in-between point
Body punch 2 is designed to the cylindrical male connecting portion of Φ 400mm, mold sheet corresponding thereto with 1 connecting portion of die ontology
The cylindrical female connection portion that body 1 matches and interference volume is used to coordinate for the interference mode of 0.50~0.60mm；According to mold
Material be 5CrNiMo characteristic, by the die ontology 1 with female connection portion be heated to 400 DEG C ± 10 DEG C heat preservation 2 hours after,
Split punch 2 corresponding to what it is with male connecting portion is socketed on one.Mold material object is shown in figure.
Economic analysis before and after die improvement：
By 1000 forging of production, often produce 100 forging and prepare a mold.
Before improvement：9 pieces of molds need to be prepared altogether by having produced, and every piece of base mould material expense, manufacturing cost, heat treatment expense are closed
About 150,000 yuan, altogether about 1,350,000 yuan of meter；
After improvement：It only needs to prepare about 150,000 yuan of a mold；Prepare 9 pieces of split punches, every block of split punch raw material
Expense, manufacturing cost, heat treatment expense add up to about 30,000 yuan, about 420,000 yuan altogether；
By above-mentioned calculating, 1000 forging have been produced, about 930,000 yuan of fund can be saved.
Claims (3)
