Description
Technical field
The invention belongs to tableware production technical fields, are specifically related to a kind of production table fork blank automatic blanking punching press dress
It sets and its application method.
Background technology
Table fork is one kind of tableware, and fork one end allows people to hold work, and the other end has two to four branches, for being inserted into or containing
Food.Auxiliary user takes food in mouth to, also can catch food when cooking or cutting food, be moved so as not to food.
The prior art needs the first punching press from plate to obtain the blank of table fork, as shown in figure 4, being in the production of table fork
Flitch status diagram when punching press obtains blank from flitch, plate 15 are a strip board, are slightly wider than the length of fork blank
Degree, during punching press, before operator is seated at press bed, by flitch it is flattened enter upper/lower die between and flitch withstood on into lower die
On the positioning plate of tool, after the next blank of punching press, flitch is overturn into punching press again, then overturn, then punching press, it is reciprocal with this so that
If flitch undershoot depress flakes 24, this mode of production there are the problem of be to be stamped on flitch 15 after blank 24, flitch
The remaining waste material of continuous wave pattern shape on 15.This waste material is as flitch constantly overturns, stamping procedure, and still band is in flitch
On, it can not automatic cutting, it is necessary to which operator often overturns once, and disconnected waste material is broken with hand, and otherwise flitch front end is undulatory useless
Material, position to be processed can not top pressure to the positioning plate of lower grinding tool, can not just continue punch process, be made moreover, being easy to scratch finger
At injury, if in addition, not breaking disconnected very fine crushing, each corrugated waste material intersection is stirred together, is unfavorable for collecting and be taken up an area
Area is very big.It is very big which results in labor intensities, and efficiency is low.
It is a kind of simple in structure there is an urgent need to occur to solve this technical problem, it is easy to use, it is produced for table fork blank
