Abstract
The utility model discloses a punching die scrap material ejecting mechanism, and relates to a die part. The punching die scrap material ejecting mechanism comprises an upper die seat, a die handle and a punch-die. The punch-die is fixedly connected with the lower surface of the upper die seat and provided with a punching type hole. The punching die scrap material ejecting mechanism further comprises a push rod which is arranged inside the punching type hole and can move relative to the punch-die, the upper end of the push rod is connected into the upper die seat through a spring, and when the spring is in a free state, the lower end of the push rod extends out of the lower end face of the punch-die. According to the punching die scrap material ejecting mechanism, scrap materials can be discharged automatically after punching each time, so that spalling of the punch-die caused by stacking of the scrap materials is avoided, machining cost is lowered, work efficiency is improved, and practicability is achieved.
Description
Technical field
The utility model relates to a kind of mold component, relates in particular to a kind of stamping die waste material ejecting mechanism.
Background technology
Punching press is at room temperature to utilize the mould that is installed on the forcing press that material is exerted pressure, and makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.Diel is the requisite technological equipment of punching production, is technology-intensive product, and it can carry out the processing and forming such as punching, blanking, bending and pull and stretch.The quality of stamping parts, production efficiency and production cost etc. have direct relation with Design of Dies and manufacturing.For the compound die that blanking and punching can be finished simultaneously, waste materials in stamping is easy to be stuck in the punching hole type hole of punch-die, if the untimely discharge of waste material; then may pile up the spalling punch-die; must shutdown maintenance or change punch-die, increased processing cost, reduced operating efficiency.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of stamping die waste material ejecting mechanism, can automatically discharge waste material after each punching press, avoided waste from stacking spalling punch-die, reduce processing cost, improved operating efficiency, very practical.
The technical solution of the utility model is: a kind of stamping die waste material ejecting mechanism, comprise upper bolster, die shank and punch-die, punch-die is fixedly connected on the upper bolster lower surface, have the punching hole type hole on the punch-die, also comprise push rod, push rod is arranged in the punching hole type hole and can moves relative to punch-die, and the push rod upper end is connected in the upper bolster by spring, when spring was in free state, the lower surface of punch-die was stretched out in the lower end of push rod.
As preferably, described upper bolster adopts the Q235 steel to make, and described punch-die adopts the GCr15 steel to make, and is provided with backing plate between punch-die and the upper bolster, and described backing plate adopts 45 steel to make.
As preferably, have through hole on the upper bolster, be provided with internal thread in the through hole, screw thread is connected in the through hole, and spring housing is connected on the screw; The push rod lower surface is the conical surface.
The beneficial effects of the utility model are: punch-die punching hole type of the present utility model is provided with push rod in the hole, when upper bolster moves down, push rod relative punch-die under the effect of piercing punch moves, and piercing punch is finished punching, when moving on the upper bolster, push rod is got back to initial position under the effect of spring, waste material is released, avoided waste from stacking spalling punch-die, needn't frequently keep in repair or change punch-die, reduce processing cost, improved operating efficiency.When spring damages or lost efficacy, screw can be taken out, change spring, very convenient and practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of stamping die waste material ejecting mechanism comprises upper bolster 3, die shank 4 and punch-die 1, and punch-die 1 is fixedly connected on upper bolster 3 lower surfaces, have the punching hole type hole on the punch-die 1, also comprise push rod 8, push rod 8 is arranged in the punching hole type hole and can moves relative to punch-die 1, and push rod 8 upper ends are connected in the upper bolster 3 by spring 6, when spring 6 was in free state, the lower surface of punch-die 1 was stretched out in the lower end of push rod 8.In the present embodiment, as preferably, have through hole on the upper bolster 3, be provided with internal thread in the through hole, screw 5 is threadedly connected in the through hole, and spring 6 is socketed on the screw 5, when needing, can take out screw 5 and change spring 6, and is very convenient.
In the present embodiment, as preferably, described upper bolster 3 adopts the Q235 steel to make, good combination property, and long service life, described punch-die 1 adopts the GCr15 steel to make, and intensity is high, and is not fragile.Be provided with backing plate 7 between punch-die 1 and the upper bolster 3, described backing plate 7 adopts 45 steel to make, the impact of 1 pair of upper bolster 3 of punch-die when backing plate 7 can reduce punching press, the service life of prolongation upper bolster 3.Push rod 8 lower surfaces are the conical surface, the release of more convenient waste material.
Operation principle of the present utility model is: when upper bolster 3 moves down, push rod 8 relative punch-die 1 under the effect of piercing punch moves, piercing punch is finished punching, when moving on the upper bolster 3, push rod 8 is got back to initial position under the effect of spring 6, waste material is released, avoided waste from stacking spalling punch-die 1.
More than a kind of stamping die waste material ejecting mechanism provided by the utility model has been carried out detailed introduction, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.To change of the present utility model with to improve will be possible, and can not exceed design and the scope that accessory claim can be stipulated.
