The automobile exhaust system fixing-type clamp die has the advantages of being high in material utilization ratio, high in production efficiency and stable in quality.

Description

A kind of automobile exhaust system fixing hoop mould

Technical field

The present invention relates to a kind of mould, relate in particular to a kind of automobile exhaust system fixing hoop mould.

Background technology

The automobile exhaust system fixing hoop is widely used in automotive field at present, technology of die manufacturing have moulding fast, can realize batch machining, guarantee the advantages such as machining accuracy, the mode of punching press is just used in the production of automobile exhaust system fixing hoop at present mostly, but because existing method continuous punching bending difficulty is large, be difficult to a mold forming, not only waste time and energy, also can increase cost of labor, production efficiency is low, also can cause simultaneously the inaccurate of the waste of materials'use and precision.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of automobile exhaust system fixing hoop mould that stock utilization, production efficiency and product quality are significantly promoted.

For achieving the above object, the invention provides a kind of automobile exhaust system fixing hoop mould, comprise upper die component and lower membrane module, described upper die component comprises upper bolster, backing plate and punch retainer, described lower membrane module comprises die shoe, die block and stripper, material strip is between upper die component and lower membrane module, on described punch retainer, be fixed with the punch assemblies for punching press, and corresponding to the position of described punch for punching press, be fixed with described punch the same number of at described die block, die assembly with described punch shape complementarity, described punch assemblies comprises that one for the U-shaped punch of moulding, a punch for punching, two punch for 30 ° of bendings, three for 45 ° of bendings, punch for 90 ° of bendings and one are be used to cutting the punch of rim charge, described die assembly comprises that one for the U-shaped die of moulding, a die for punching, two dies for 30 ° of bendings, three for 45 ° of bendings, die for 90 ° of bendings and one are be used to cutting the die of rim charge.

As preferably, described piercing punch is provided with two, and punching concave die is provided with two.

As preferably, on described stripper, be fixed with the stripper baffle plate for de-material.

As preferably, described stripper baffle plate is fixedly connected with the side of stripper.

As preferably, described upper bolster, backing plate and punch retainer are fixedly connected sequentially from top to bottom.

As preferably, described die shoe, die block and stripper are fixedly connected sequentially from top to bottom.

As preferably, described stripper baffle plate is fixedly connected with by set screw with the side of stripper.

Good effect of the present invention is: stock utilization is high, and production efficiency is high, stay in grade.
