Description

A kind of flanging mould of automobile engine turbine case

Technical field

The present invention relates to mechanical field, and in particular to a kind of flanging mould of automobile engine turbine case.

Background technology

Turbocharging (Turbo Boost), is that one kind utilizes internal combustion engine (Internal Combustion Engine) fortune The technology for the exhaust gas driven air compressor (Air-compressor) for changing the line of production raw.

Turbo charged main function is exactly to improve air input of engine by air, so as to improve the power and moment of torsion of engine, is allowed Car is energeticallyer.One engine is loaded onto after turbocharger, its peak power when without booster compared with can increase Plus 40% even more high.Bigger work(can exported after supercharging by so also implying that the engine of same one Rate.

At present, the forming process of the powering turbines shell of automobile is generally by diel punch forming, existing side In case, product is caused to occur the bad phenomenons such as necking down, cracking and corrugation, drop in punching course often due to mold design is improper Low production efficiency, scrappage hands over original text.

The content of the invention

It is an object of the invention to provide a kind of flanging mould of automobile engine turbine case, to solve existing skill Above-mentioned multinomial defect caused by art.

A kind of flanging mould of automobile engine turbine case, including die shoe, forming convax mould, molding concave die, on Die-cushion plate and upper bolster, the forming convax mould are arranged on die shoe, and the molding concave die, upper die plate and upper bolster connect successively Connect, die shoe is connected by guiding mechanism with upper bolster, be additionally provided with blank body, the upper die plate and pacify on the die shoe Equipped with unloading mechanism, the stamping surface center of the upper bolster, which is provided with alignment pin, upper bolster, is additionally provided with some balance weights.

It is preferred that, the unloading mechanism includes material returned bar and back-moving spring, and back-moving spring is installed on the groove on upper bolster Interior, material returned bar is slidably connected in molding concave die and its top is contacted with back-moving spring, and the quantity of material returning structure is 4.

It is preferred that, the material returned bar is shaped as " T " font.

It is preferred that, the material returned bar particular by sliding sleeve be arranged on molding concave die in.

It is preferred that, the push rod vertical with lower template is additionally provided with the mold foot pad, push rod passes through lower template and its top Connection is contacted with blank body.

It is preferred that, the quantity of the guiding mechanism is 4.

The advantage of the invention is that:The present invention is molded by the way of the first binder aftershaping of upper and lower mould, with adjustment Balance the height of cushion block to adjust the size of pressure-pad-force, make it avoid product necking down, cracking, corrugation etc. occur in production bad Phenomenon, so as to improve production efficiency, reduce product rejection rate.

Embodiment

To be easy to understand the technical means, the inventive features, the objects and the advantages of the present invention, with reference to Embodiment, is expanded on further the present invention.

As shown in figure 1, a kind of flanging mould of automobile engine turbine case, including die shoe 2, forming convax mould 10th, molding concave die 5, upper die plate 7 and upper bolster 6, the forming convax mould 10 are arranged on die shoe 2, the molding concave die 5, Upper die plate 7 and upper bolster 6 are sequentially connected, and die shoe 2 is connected by guiding mechanism 3 with upper bolster 6, on the die shoe 2 also Provided with blank body 12, unloading mechanism 8 is installed on the upper die plate 7, the stamping surface center of the upper bolster 6 is provided with Some balance weights 4 are additionally provided with alignment pin 9, upper bolster 6.

In the present embodiment, the unloading mechanism 8 includes material returned bar 81 and back-moving spring 82, and back-moving spring 82 is installed on In groove on die holder 6, material returned bar 81 is slidably connected in molding concave die 5 and its top is contacted with back-moving spring 82, and the material returned The quantity of structure is 4.

In the present embodiment, the material returned bar is shaped as " T " font.

In the present embodiment, the material returned bar particular by sliding sleeve be arranged on molding concave die 5 in.

In the present embodiment, the push rod 11 vertical with lower template is additionally provided with the mold foot pad 1, push rod 11 passes through lower mould Plate and its top contacts connection with blank body 12.

In addition, the quantity of the guiding mechanism 3 is 4.

The course of work and principle:

This mould installion is produced on 400T hydraulic presses;

(1) slider of oil press rises to setting height, and mould parts 5,6,7,8 are separated with press slide with lower mould, now Unloading mechanism 8 ejects cavity plate in the presence of spring force;

(2) press is taken blame for others to rise and the jack-up of blank body 12 to convex mould surface is flushed, and blank is placed on positioning by operative employee On pin 9;

(3) press slide is moved downward, and the guiding mechanism 3 of upper and lower mould is contacted, and molding concave die 5 and blank body 12 are blank Push down and adjust size and evening ratio in flanging by adjusting balance pad tile height;
