Description

Point sword cutting die

Technical field

The utility model relates to cutting die, is specifically related to a kind of point sword cutting die.

Background technology

Stamping-out is the operation that plate is separated, and common blank operation comprises blanking, punching, trimming, otch etc. For non-metallic material, such as leather, felt, cardboard, cloth, asbestos and various thermoplastics films etc., it is also possible to adopt the punch press process identical with metallic substance. The existing stamping-out mode for non-metallic material just adopts the punch simply with cutting edge to carry out stamping-out, goods after stamping-out and waste material substantially by manual cleaning, inefficiency, and dangerous.

Practical novel content

The utility model can carry out automatic stripping simultaneously and unload the sharp sword cutting die of waste material after being intended to provide a kind of stamping-out.

Sharp sword cutting die in this scheme, comprise die holder, the bottom of die holder is provided with the blanking die of ring-type, the lower end of blanking die has outer point sword, die holder has and vertical crosses hole, crosses that be provided with in hole can the piercing punch of ring-type of vertical motion, the lower end of piercing punch has interior point sword, piercing punch is positioned at the ring of blanking die, is provided with the push piece plate of the ring-type that can vertically move, is provided with the charging ram that can vertically move in the ring of piercing punch between piercing punch and blanking die.

Principle of work of the present utility model is as follows: the lower section that goods are placed in this cutting die, in order to protect piercing punch, can at goods bottom pad one piece of hardwood pad, laminate or cardboard, and to protect point, sword is unlikely bursts apart. Driving piercing punch descending by power mechanism, goods are carried out punching, after punching, in piercing punch backhaul process, push piece plate and charging ram are simultaneously descending to be unloaded goods and waste material from piercing punch respectively.

The utility model has the advantage of: by arranging the push piece plate of the ring-type that can vertically move between piercing punch and blanking die, the charging ram that can vertically move is set in the ring of piercing punch, the discharging of goods and waste material can be realized simultaneously, substantially increase the efficiency of punching.

Further, the upper end of push piece plate is provided with a convex circle of circle, and the upper end inwall of blanking die is provided with a ring platform, and the lower surface of convex circle can offset with the upper surface of land. Push piece plate is arranged between piercing punch and blanking die, and the motion of push piece plate is played the effect of guiding by both, by coordinating of convex circle and land, the lower stroke of push piece plate is had position-limiting action.

Further, hole is up-small and down-big ladder hole excessively, and upper mistake in hole is provided with spring, and lower end and a push rod of spring are fixed, and the bottom of push pedal is respectively equipped with push rod, and the lower end of push rod and the upper end of push piece plate are fixed. There is provided thrust by spring power to push piece plate, conveniently carry out discharging.

Further, the upper top crossing hole is provided with internal thread, and a screw is threaded with upper hole of crossing, and spring is positioned at the periphery in screw rod portion, and the upper end of spring and the head of screw are fixed. Owing to screw is threaded with upper hole of crossing, therefore rotary screw is with regard to the vertical position of adjustment screw, and then the elastic force of regulating spring, thus regulates the reactive force to push piece plate.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment.
