Description
Technical field
The manufacture mould for automobile rear driving axle brake oil pipe holder is the utility model is related to, especially a kind of braking
Device oil tube bracket blanking-rush scallop composite die.
Background technology
Brake oil pipe holder is one of indispensable accessory for fixing and supporting all kinds of oil pipes and wire harness on rear driving axle, and it is straight
Connect the layout for affecting all kinds of oil pipes and wire harness and installation is fixed.It is by fabrication processing traditional at present：Blanking → blanking
→ scallop (i.e. because hole back gauge is less than 1.2 times of thickness of slab) is rushed, to reach product design requirement.This production technology production efficiency
Low, production cost is high.And traditional punching press mode structure is that guide pin bushing, guide pillar are directly anchored in upper and lower template at present, between mould
Gap is controlled by pincers worker manual skill completely, and such Mold Making precision is difficult to ensure that, and guide plate only plays discharging and do not had
Play the role of to be oriented to compound die.Therefore it can separately ward off small stream footpath and design and produce out a kind of new brake oil pipe holder blanking-rush tooth
Shape hole composite die and combination process, production efficiency is improved, ensure product quality, be just particularly important.I.e. first：Mould is set
Guide pillar, the guide sleeve structure of automatic correcting gap are counted, the uniformity of upper and lower die clearance does not just control by pincers worker manual skill, but
Ensure by machine finish；Second：Mould sets up a school mold structure, such piercing punch and blanking die position degree
With piercing punch and the uniformity of compound die punch clearance, just fitter assembly is not leaned on to control by hand, but come from by school mold
It is dynamic to ensure；3rd：Mould sets up a guide board structure to improve the intensity of compound die (because the wall at the most thin cutting edge of compound die
Thickness only has 3.3mm, and thickness of slab is 3.0mm, i.e., hole back gauge is less than 1.2 times of thickness of slab, and such compound die is easy for ftractureing).
Chinese patent notification number is that CN103687692A discloses a kind of disc type for being used for manufacture for motor vehicle braking system
The method of the arrester bracket of brake, the arrester bracket have at least one guiding recess, this at least one guiding recess
