Abstract

The invention provides a punching and raising die for an upper reinforcing plate of a back door wiper. One die finishes raising and punching processes simultaneously, so that the processing period is shortened, processing efficiency is improved, the reserve of a set of die is reduced, and production cost is reduced. The die comprises an upper die plate and a lower die plate, wherein an upper die is arranged on the lower part of the upper die plate; a lower die is arranged on the lower die plate; the upper die plate and the lower die plate are connected through a sliding guide pillar group; a raising head is arranged in the center of the upper die; punching heads are arranged on the two transverse sides of the raising head; and the lower die is provided with a raising male die and punching female dies which correspond to the raising head and the punching heads respectively.

Description

The punching raising mould of back door windscreen wiper upper reinforcing plate

Technical field

The present invention relates to the punch process field of auto parts and components, especially relate to automotive back door windscreen wiper upper reinforcing plate processing unit (plant) field, be specially the punching raising mould of back door windscreen wiper upper reinforcing plate.

Background technology

Automotive back door windscreen wiper upper reinforcing plate, as depicted in figs. 1 and 2, need to its arcwall face top carry out raising processing, with and transverse ends carry out punching processing, in conventional machining process, raising processing and punching processing are two procedures, processing respectively, single die is used respectively in raising, punching, stiffener carries out needing again the dismounting mould to carry out punching processing after raising processing, and the process-cycle is long, and the customization of raising mould and punching die two molds has simultaneously improved production cost.

Summary of the invention

For the problems referred to above, the invention provides the punching raising mould of back door windscreen wiper upper reinforcing plate, the one mould is completed simultaneously and is beaten recessed and punching two procedures, shortened the process-cycle, improve working (machining) efficiency, reduced simultaneously the deposit of a mold, reduced production cost.

Its technical scheme is such, the punching raising mould of back door windscreen wiper upper reinforcing plate, it comprises cope match-plate pattern and lower bolster, under described cope match-plate pattern, upper die structure is installed, on described lower bolster, lower die structure is installed, described cope match-plate pattern be connected lower bolster and connect by slip guide pillar group, described upper die structure central authorities are provided with the raising drift, described raising drift both lateral sides is equipped with pierce punch, and described lower die structure corresponding described raising drift, described pierce punch respectively is provided with raising punch, punching concave die.

It is further characterized in that:

Described upper die structure comprises upper mounted plate and upper padding plate, and the fixed plate is fixed under described upper padding plate, and described upper padding plate is fixed under described cope match-plate pattern;

Described lower die structure comprises bottom plate and lower bolster, and described raising punch and described punching concave die are fixed on described bottom plate, and described bottom plate is fixed on described lower bolster, and described lower bolster is fixed on described lower bolster;

Described slip guide pillar group comprises guide pin bushing and guide pillar;

It is further characterized in that:

Described upper die structure also comprises stripper, and described stripper is fixed under described fixed head by the discharging backing plate; In described stripper, corresponding described raising primary drying head, described pierce punch arrange respectively the edge body, described raising drift, described pierce punch pass respectively described bottom plate, stripper backing plate and corresponding edge body from top to bottom.

After adopting structure of the present invention, its beneficial effect is: its dozen of back door windscreen wiper upper reinforcing plate recessed with punching in together with in-process complete, shortened the process-cycle, improved working (machining) efficiency, reduced the mould deposit, reduced production cost.
