Description

Stamping die for caster bracket

Technical Field

The invention relates to a stamping die for a caster bracket.

Background

The caster is widely applied to furniture and medical equipment, and the support on the caster is generally subjected to punch forming through multiple processes in production.

The prior art requires 3 punch presses, 3 sets of dies, and multiple operators to complete the part. The processing procedures are complicated, and the stability of the product quality is difficult to guarantee due to the turnover of a plurality of procedures.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a stamping die for a caster bracket.

The utility model provides a stamping die for truckle support, includes consecutive last membrane module and lower membrane module, last membrane module and lower membrane module all include from left to right consecutive punching process mold insert, first idle step process mold insert, first hole chamfer process mold insert, cut material process mold insert, second hole chamfer process mold insert, press arc process mold insert, punching process mold insert, third hole chamfer process mold insert, second idle step process mold insert and blanking shaping process mold insert.

Preferably, the upper die base comprises an upper die base, an upper base plate, an upper clamping plate, a stop plate and a material supporting plate which are sequentially connected from top to bottom.

Preferably, the lower die holder comprises a lower bottom plate, a lower backing strip, a lower die holder, a lower backing plate, a lower clamping plate and a lower die plate from bottom to top.

Preferably, the piercing process insert comprises a piercing punch located within the upper die assembly.

Preferably, the insert for the material shearing process comprises a material shearing punch head, and the material shearing punch head is positioned in the upper die assembly.

Preferably, the blanking forming process insert comprises a second forming punch positioned in the upper die assembly and a forming blanking lower die core positioned in the lower die assembly, the second forming punch is detachably mounted in the upper die assembly, and the forming blanking lower die core is detachably mounted in the lower die assembly.

Has the advantages that:

3 loaded down with trivial details manufacturing procedure merge into one set and upgrade the mould, once only process out the finished product, save 2 sets of moulds, save manufacturing procedure 2, save the processing personnel, eliminate material circulation between each process simultaneously.

Firstly, a material steel belt is fed into a die cavity by adopting a feeder of a punch press, a stepping stroke is set, accurate feeding of each station is completed, and a positioning pin and a material returning thimble are designed on the material shearing position of the die for ensuring the feeding accuracy;

in order to ensure the appearance quality requirement of the part, the punching and trimming are required to have no burrs, three chamfering stations are added to the die design, and the burrs after trimming can be eliminated;

the problems that a forming station is easy to damage, a die is maintained and the like are considered in the design of the die, the forming station is independently installed in a split mode, and when a forming punch and a lower die core are replaced, the whole die does not need to be disassembled.
