Description
Technical field
The present invention relates to mechanical forging field, more particularly to a kind of braking automobile to process stamping machine with piston element.
Background technology
Stamping machine is often widely used, by stamping machine and mould as a kind of forging equipment among mold casting process
Have and external force is applied to tabular billot, billot is produced plastic deformation or separation, so as to obtain the stamping parts of required shape and size.
Punching press includes two kinds of deformation process and separation circuit, and separation circuit is also referred to as punched, and the purpose is to make stamping parts along certain contour line
Separated from billot, while ensure to separate the quality requirement of section.The purpose of forming process is the condition for making billot in not broken base
It is lower to be plastically deformed, the blank of required shape and size is made, but stamping machine has very big danger using process
Danger, stamping machine is during mould punching is carried out, and in order to which mould punching is molded, drift and strength during contacting dies are non-
Chang Ju great, so there is very high requirement to the intensity of mould, but be present significant limitation in overall mould, rushed
Stress can be concentrated during pressure, and so as to cause crack of die, as shown in 6 ＇, mold failure is that asking for appearance is easiest in punching production
Topic, often results in stopping production, influences life cycle of the product；On the other hand, the die cost of punching production is high.Usual mould expense accounts for system
The 1/5-1/4 of part totle drilling cost.Because Making mold difficulty is big, cost is high, the mould after putting into production is repaired and sharpening dimension
Shield expense is also high, and the original cost of mould only accounts for 40% or so of whole die cost., can be with it is therefore prevented that burn failure
Substantially reduce the die cost of punching production.
The content of the invention
The purpose of the present invention is in view of the deficiencies of the prior art, to overcome because mould local stress causes mould early stage
The problem of abrasion rupture, there is provided a kind of spliced mould of insert, change unitary mould are the spliced mould of insert.
The corresponding adjustment of the technology of the present invention is as follows：
A kind of braking automobile processes stamping machine, including upper machine body, lower body, upper bolster, die shoe, upper mould with piston element
Tool, lower mould, fixed plate, side pressing block, stop collar, guide pillar, bearing platform and thimble rod；Side pressing block is fixed on lower mould；It is spacing
Set is fixed on the outside of guide pillar, positioned at the top of bearing platform；Guide pillar is fixed on side pressing block and die shoe both sides；Upper bolster is fixed on
On upper machine body；Die shoe is fixed on bearing platform, and the hole with one for thimble rod relative motion；Bearing platform is fixed on down
On body, and the hole with one for thimble rod relative motion；Lower mould is placed between side pressing block and die shoe；
Lower mould includes outer ring die, interior ring mould and connecting key, and interior ring mould is placed in outer ring die, passes through connecting key
Connection.
As an improvement, outer ring die is in integrally annular, inside has the first groove, the second groove, first groove,
Second groove symmetrically opens up, and outer ring die external diameter is D, and internal diameter d, the value of the D/d is in the range of 1.6~2.5.
As an improvement, D/d value is 1.8.
As an improvement, interior ring mould is integrally rounded, edge part has the first breach, the second breach, first breach,
Second breach symmetrically opens up, and interior ring mould external diameter is d.
As another improvement, connecting key is integrally triangular in shape, and the first groove lacks with interior ring mould first inside outer ring die
Mouth is corresponding, the second groove is corresponding with the interior breach of ring mould second inside outer ring die, is connected both by connecting key.
As another improvement, the fit system of outer ring die and interior ring mould is interference fit.
As another improvement, connecting key is divided into Part I, Part II, and Part I is located at the first groove and second recessed
In groove, Part II is located in the first breach and the second breach.
Improved as further, the Part I of connecting key and Part II are equal in vertical height.
Improved as further, interior ring mould there are two holes stretched into for thimble rod push rod；Thimble rod, there are two and push away
Bar, and be fixed among lower body；The pusher section of thimble rod is from bearing platform to lower mould, and thimble rod runs through lower body, held
Weight platform, die shoe and lower mould, pass through bearing platform, die shoe and the pilot hole set by lower mould.
Improved as further, lower mould is made up of high-speed steel.
The beneficial effect of the present embodiment：The present invention is to provide a kind of spliced mould of insert, overcomes because mould is local
The problem of stress causes mould premature wear to rupture, change unitary mould are the spliced mould of insert, unitary mould stress concentration,
Die life can be shortened, causing the precision of workpieces processing reduces, and block insert type mould fully solves the problems, such as mould local stress, should
Power is graded processing, is born respectively by outer ring die together with interior ring mould, and after stress is scattered, mould strength improves, and improves
Die life, improve working efficiency.
