Description
Technical field
The utility model is related to a kind of side top punch-forming molds of magnesium alloy front case of vacuum booster.
Background technology
Vacuum booster for vehicle brake is the safety member in vehicle braking system.Pass through the vacuum in control chamber and air
Pressure difference realizes the amplification to operator brake pedal power, drives foundation brake component, realizes the braking of vehicle.Wherein power-assisted
The weight of the front and rear housings of device accounts for the nearly half of assembly weight.
The mass density of magnesium alloy is generally in 2g/cm3Left and right, it is lighter than steel by about 77%, replace steel, energy with magnesium alloy
Mitigate the weight of booster significantly.
But the ductility of magnesium alloy is relatively poor, when punch process, easily wrinkles or drawing crack, and stamping press is difficult to control
System, difficulty of processing is big, and yield rate is low.
And magnesium alloy usually occurs powder in punching press and is bonded in stamping die, causes product surface garland, shadow
Ring product quality and die life.
Utility model content
Technical problem to be solved in the utility model is：A kind of formed precision height, the magnesium alloy of high yield rate are provided

Portion, the position in upper forming blocks when corresponding to shaping at the top of workpiece are equipped at least two floating binder pins；Die holder is equipped with
Lower bracing frame is provided with lower mounting seat in lower bracing frame, and lower mounting seat is equipped with lower forming blocks, and lower forming blocks surface includes and work
The matched retainer face in the molded portion of part and the forming surface for profiled side top, set on lower forming blocks upper surface there are two
With the matched positioning pin of workpiece upper Positioning holes, the upper forming blocks are equipped with corresponding avoid holes, in lower mounting seat it is lower into
Type block periphery is equipped with up and down with the upper matched holding pad in forming blocks binder portion, and lower mounting seat is equipped with ejection holding pad
Spring, holding pad upper surface just holds in the palm the workpiece bottom for holding and being placed in lower forming blocks in free state, in lower mounting seat
Holding pad outside is equipped with a pair of of locating piece, and holding pad side is equipped with limited step at corresponding to locating piece, is set on locating piece
Have and positioning step is matched prevents holding pad from moving upwards excessive restriction protrusion, lower mounting seat is provided through on die holder
The nitrogen gas spring being connected with holding pad, the nitrogen cylinder of all nitrogen gas springs is interconnected by pipeline on die holder, and lower peace
The pressure gauge that seat is equipped with measurement nitrogen cylinder pressure is filled, four binder gap adjustment blocks, binder gap tune are additionally provided on holding pad
The height of monoblock is the 105%-108% of flitch thickness.
As a preferred solution, the molded surface of the upper forming blocks and lower forming blocks first carries out subzero treatment, so
PVD coatings are sprayed afterwards.
The beneficial effects of the utility model are：The nitrogen being connected due to being provided through lower mounting seat on die holder with holding pad
Gas spring, the nitrogen cylinder of all nitrogen gas springs is interconnected by pipeline on die holder, and lower mounting seat is equipped with measurement nitrogen
The pressure gauge of cylinder pressure can accurately control the pressure of nitrogen gas spring, but also entire mould inner pressure is uniform, make the stream of material
Dynamic deformation rate is consistent, so as to avoid the drawing crack or corrugation feelings frequently occurred due to magnesium-aluminium alloy material ductility itself is bad
Condition；Due to the 105%-108% that the height of binder gap adjustment block is flitch thickness, the material of magnesium alloy is more suitable for, more
Corrugated happen is avoided well.This mold admirably solves situations such as corrugation cracking of housing, substantially increases magnesium
The yield rate of Al-alloy casing, reduces production cost so that light-weighted magnesium alloy housing can be widely applied, to meet
The demand that automobile industry reduces energy consumption.
Since the molded surface of upper forming blocks and lower forming blocks first carries out subzero treatment, PVD coatings are then sprayed so that plate
Mobility during material punching press is more preferable, improves forming quality, in addition avoids magnesium alloy powder and be bonded in stamping die, cause
Product surface garland, influences product quality and die life.
