What the side direction used in current cold punching die rushed that hole flanging punch structure plays ejector pin structure for band rushes hole flanging punch; this punch head blade mouth-shaped is generally circle; in process of production; the waste material swept away is cone shape; easily take on counterdie die or drift; cause needing often to stop clear away waste in production process, have a strong impact on productive temp, production efficiency is low.
Summary of the invention
The purpose of this utility model be exactly to provide a kind of production efficiency high, be not required to be clear away waste and the side direction affecting productive temp rushes hole flanging punch.
For achieving the above object, the side direction designed by the utility model rushes hole flanging punch, comprises the hole flanging punch being provided with inner chamber, the cylindrical pierce punch being fixed on hole flanging punch front end, is provided with elastic component and ejector beam in described inner chamber; One end of described elastic component is fixedly connected on the rearward end of described hole flanging punch, described ejector beam is fixedly connected with the other end of described elastic component and by elastic component elastic activity in the lumen, described pierce punch is stretched out in one end of described ejector beam under the indeformable state of elastic component, it is characterized in that: the front end circumference of described pierce punch angularly evenly offers multiple arc groove.
Preferably, the front end circumference of described pierce punch angularly evenly offers four arc grooves.
Fixed cover gone back by described ejector beam and is provided with fixed pin shaft, the other end of described elastic component is fixedly connected on described fixed pin shaft.
One end of described elastic component is bolted to connection the rearward end at described hole flanging punch.
The second joint portion that described hole flanging punch comprises the first joint portion and is connected with the first joint portion rear removable formula, one end of described elastic component is fixedly connected on the rearward end of the second joint portion.
Described first joint portion is threaded with the second joint portion.
Described second joint portion rearward end has screwed hole, and described bolt is fixed in screwed hole, and one end of described elastic component is fixedly connected on bolt.
The utility model has the advantage of: side direction in prior art is rushed the circular cutting edge of hole flanging punch and change cross cutting edge into; to become sub-circular plane from coniform for the waste material shape then swept away; thus allow waste material not easily be with on die or drift; avoid the operation of the clear away waste that needs to stop; meet the requirement of productive temp, production efficiency is high.
Accompanying drawing explanation
Fig. 1 is that a kind of side direction rushes hole flanging punch structural representation;
Fig. 2 is hole flanging punch structural representation in Fig. 1;
Fig. 3 is the top view of pierce punch in Fig. 1;
In figure: 1-hole flanging punch (1a-first joint portion, 1b-second joint portion), 2-pierce punch, 3-ejector beam, 4-elastic component, 5-bolt, 6-arc groove, 7-inner chamber, 8-fixed pin shaft.
Detailed description of the invention
The utility model is further illustrated below in conjunction with drawings and Examples.
See Fig. 1 and Fig. 3, the utility model comprises the hole flanging punch 1 being provided with inner chamber 7, the cylindrical pierce punch 2 being fixed on hole flanging punch 1 front end, the front end of described hole flanging punch 1 is provided with the taper seat that can carry out flange to punching, and this is ripe prior art, seldom repeats in this; Be provided with elastic component 4 and ejector beam 3 in described inner chamber 7, described elastic component 4 can be spring or other elastic constructions; One end of described elastic component 4 is fixedly connected on the rearward end of described hole flanging punch 1, described ejector beam 3 is fixedly connected with the other end of described elastic component 4 and by elastic component 4 elastic activity in inner chamber 7, described pierce punch 2 is stretched out in one end of described ejector beam 3 under the indeformable state of elastic component 4, contacting retrude at ejector beam 3 with outside flitch returns in pierce punch 2, and the front end circumference of described pierce punch 2 angularly evenly offers multiple arc groove 6.Rushing after hole flanging terminates, the waste material swept away outwards ejects and drops by ejector beam 3 resilience, in prior art, pierce punch 2 is cylinder, under the effect impacted with joint efforts with ejector beam 3, the waste material swept away is for conical, still can be with after ejector beam 3 resilience ejects in drift or hole groove, the front end circumference of pierce punch 2 is angularly evenly offered multiple arc groove 6 by the utility model, conical waste material can be become and be similar to circular plan shape waste material, easily ejected by ejector beam 3, avoiding waste material is linked with on drift or in the groove of hole, do not need the clear away waste that stops aborning, meet the requirement of productive temp, production efficiency is high.
Preferably, the front end circumference of described pierce punch 2 angularly evenly offers four arc grooves 6, and it is cross shape that the front end of pierce punch 2 cuts off cutting edge, and the waste material cut is similar to disk, more easily comes off.
