Abstract

The invention provides a die for punching a lower reinforcing plate of an engine cover lock. The die can be used for punching flanging holes and positioning holes of the lower reinforcing plates of different series of engine cover locks, so that the manufacturing cost and maintenance cost are reduced to reduce the production cost further. The die comprises an upper die plate and a lower die plate, wherein the upper die plate is connected with the lower die plate by a guide pillar and a guide sleeve; an upper die structure is arranged on the lower side of the upper die plate; and a lower die structure is arranged on the lower die plate. The die is characterized in that the lower die structure comprises three inserts, namely a flanging hole female insert and two positioning hole female die inserts, and the inserts correspond to the flanging holes and the positioning holes, which are needed to be machined, of the lower reinforcing plate of the engine cover lock.

Description

Bonnet louver lower reinforcing plate punching die

Technical field

The present invention relates to engine component processing unit (plant) technical field, be specifically related to bonnet louver lower reinforcing plate punching die.

Background technology

The bonnet louver lower reinforcing plate, its structure is seen Fig. 4, Fig. 5 and Fig. 6, its flanging bore 32 and locating hole 31, the 33 general compound dies that use carry out stamping-out processing, its die, punch mostly are the mould preparation structure according to the lower reinforcing plate shape fabricating, the car system of corresponding different model or brand, its flanging bore and locating hole shape differ, and need the different die of customization, mould is made, maintenance cost is high, has improved production cost.

Summary of the invention

For the problems referred to above, the invention provides bonnet louver lower reinforcing plate punching die, the bonnet louver lower reinforcing plate of the corresponding different series of its energy carries out the stamping-out processing of its flanging bore and locating hole, has reduced manufacturing, maintenance cost, has further reduced production cost.

Its technical scheme is such, bonnet louver lower reinforcing plate punching die, it comprises cope match-plate pattern and lower bolster, described cope match-plate pattern be connected lower bolster and connect by guide pillar, guide pin bushing, under described cope match-plate pattern, upper die structure is installed, on described lower bolster, lower die structure is installed, it is characterized in that: described lower die structure comprises to be inserted, described insert be provided with three, be respectively a flanging bore die plate insert, two locating hole die plate inserts, corresponding its flanging bore of bonnet louver lower reinforcing plate to be processed and locating holes.

It is further characterized in that:

Described lower die structure also comprises stripper, bottom plate and lower bolster, described flanging bore die plate insert, locating hole die plate insert insert are in described bottom plate, described stripper is installed on described bottom plate, described bottom plate is installed on described lower bolster, and described lower bolster is fixed on described lower bolster;

Described upper die structure comprises upper mounted plate, upper padding plate and drift, described drift comprises flanging bore drift and locating hole drift, described flanging bore drift and locating hole drift are installed in the fixed plate, the fixed plate is installed under described upper padding plate, and described upper padding plate is fixed under described cope match-plate pattern;

Upper end, fixed plate right side is equipped with little guide pillar, and upper end, described bottom plate right side is equipped with little guide pin bushing, and described upper die structure and described lower die structure are located by described little guide pillar, little guide pin bushing.

[0006After adopting the present invention, its beneficial effect is: for flanging bore and the locating hole of required stamping-out, making is inserted and drift, when the lower reinforcing plate of processing different model, its overall structure is constant, only needs to change drift and die plate insert, reduced the manufacturing cost of mould, simultaneously, the use of die plate insert makes mould safeguard simpler and improve the mold use life-span, has reduced production cost.
