Description

Be applied to fixed platform of hanging of blanking drift of fine blanking mould

Technical Field

The utility model relates to a fine blanking mould technical field, in particular to be applied to fixed platform of hanging of blanking drift of fine blanking mould.

Background

In the fine blanking field, when processing the product that the product or the hole of small parts, shape are complicated and the product limit portion is close to, there are two kinds of fixed modes of blanking drift:

one is to form a threaded hole in a blanking punch by using a coordinate grinder, form a plurality of through holes corresponding to the threaded hole in an upper die, and insert a fastener, such as a screw or a fixing bolt, between the threaded hole and the through hole to fix the die. Due to the fixing mode, the arrangement of the threaded hole in the blanking punch reduces the stress area of the blanking punch, so that the upper die plate and the blanking punch are easy to deform during punching, and the normal service life of the upper die plate and the blanking punch is shortened.

And the other method is to add a T-shaped hanging platform on the blanking punch for fixing, wherein the hanging platform is used for hanging the punch, namely, a small rectangular block is additionally formed on the punch, and then a small boss with the height of about 5MM is left after grinding. However, the root of the T-shaped hanging table is easy to break in the punching process, and finally the whole punch is scrapped and the size of a punched product is affected.

Therefore, it is necessary to develop a fixing structure suitable for the blanking punch of the stamping die.
