Abstract
The utility model relates to the technical field of stamping dies, in particular to a die which prevents a workpiece and waste materials from rising by utilizing compressed air; the device comprises an upper die base plate, a male die fixing plate and a male die, wherein the male die is fixed on the male die fixing plate, the upper die base plate, the base plate and the male die are respectively provided with an upper die base plate airflow channel, a base plate airflow channel and a male die airflow channel, and the upper die base plate airflow channel, the base plate airflow channel and the male die airflow channel are sequentially connected; when blanking, the male die enters the female die from top to bottom to finish blanking, after blanking, compressed air is introduced into the air flow channel of the upper die base plate, and then sequentially enters the air flow channel of the male die through the air flow channel of the upper die base plate and the air flow channel of the base plate, and finally is blown out from the front end face of the male die, so that a workpiece or waste adhered to the front end face of the male die is blown into the opening of the female die; the utility model discloses solved effectively in stamping process finished piece or the problem that the waste material rises, and simple structure, reliable.
Description
Technical field
The utility model relates to the Stamping Die Technology field, and particularly a kind of compressed air that utilizes prevents the mould that product and waste material rise.
Background technology
Mould is assembled by each parts, during punching press, stamps out satisfactory metalwork by the upper die and lower die cooperation.
Mould is wanted the energy operate as normal, and the reliability of discharging is very important.Generally speaking, big skeletal waste we can utilize stripper to implement discharging, the fritter product that stamping-out gets off or waste material then utilize the gravity effect that it is fallen down from die, but it is also unreliable sometimes by the gravity effect, especially under the situation of high speed stamping, owing to reasons such as speed is fast, die point magnetization, may cause product or waste material to rise from the die mouth.If the product or the waste material that rise stick on the punch cutting edge plane, can influence operate as normal, when serious even can mold damage and forcing press, therefore to avoid the generation of this phenomenon, the mechanism that prevents product and waste material rising reliably just must be arranged.
At present, when general big part punching out, week leftover bits and pieces of material discharging can adopt patrix to install elastic tripper additional, and middle waste material can adopt the knockout rod in the forcing press, for the waste material in the middle of preventing is bonded on the punch, in punch, be provided with two knockout rods, but utilize the knockout rod discharging to make that mould structure is complicated, cost rises.And knockout rod only is applicable to the big part of stamping-out, and when at high speed stamping porous finding, the less centre of punch can't arrange knockout rod, therefore is unsuitable for adopting knockout rod to carry out discharging.
The utility model content
The utility model is in order to solve diel when the punching press finding, can't adopt knockout rod to prevent that product or waste material rising from causing product or waste material to stick on the punch cutting edge plane, influence the mould operate as normal, even the problem of mold damage, and a kind of compressed air that utilizes that provides prevents the mould that product and waste material rise.
For reaching above-mentioned functions, the technical scheme that the utility model provides is:
A kind of compressed air that utilizes prevents the mould that product and waste material rise, comprise upper clamping plate, backing plate, punch retainer and punch, described punch is fixed on the described punch retainer, be respectively arranged with upper clamping plate gas channel, backing plate gas channel and punch gas channel on described upper clamping plate, described backing plate and the described punch, described upper clamping plate gas channel, backing plate gas channel and punch gas channel are connected successively.
Preferably, the internal diameter of described punch gas channel along the direction of airflow from large to small.
Preferably, the internal diameter of stating the punch gas channel in the front end face place of described punch is 0.5～1mm.
The beneficial effects of the utility model are: a kind of compressed air that utilizes prevents the mould that product and waste material rise, comprise upper clamping plate, backing plate, punch retainer and punch, described punch is fixed on the described punch retainer, be respectively arranged with upper clamping plate gas channel, backing plate gas channel and punch gas channel on described upper clamping plate, described backing plate and the described punch, described upper clamping plate gas channel, backing plate gas channel and punch gas channel are connected successively; When stamping-out, punch enters die from top to bottom, finish stamping-out, after stamping-out is finished, in the upper clamping plate gas channel, feed compressed air, compressed air enters the punch gas channel by upper clamping plate gas channel, backing plate gas channel successively, and finally the front end face from punch blows out, thereby blows off in the die mouth sticking on product on the punch front end face or waste material; The utility model has solved the problem that in punching course product or waste material rise effectively, and simple in structure, reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Be further elaborated below in conjunction with 1 pair of the utility model of accompanying drawing:
The compressed air that utilizes as shown in Figure 1 prevents the mould that product and waste material rise, comprise upper clamping plate 1, backing plate 2, punch retainer 3 and punch 4, punch 4 is fixed on the punch retainer 3, be respectively arranged with upper clamping plate gas channel 11, backing plate gas channel 21 and punch gas channel 41 on upper clamping plate 1, backing plate 2 and the punch 4, upper clamping plate gas channel 11, backing plate gas channel 21 and punch gas channel 41 are connected successively.
In use for to make the air-flow velocity at punch 4 front end places not slack-off, air pressure does not diminish, and the internal diameter of punch gas channel 41 along the direction of airflow from large to small.In the present embodiment, be convenient processing, as shown in Figure 1, the internal diameter of punch gas channel 41 is divided into two parts, and top is big, and the lower part is little, so only needs just can finish by two drill bits the processing of punch gas channel 41.
In actual use, the internal diameter of the punch gas channel 41 at front end face 42 places of punch 4 is general to adopt 0.5～1mm, so the utility model, is suitable for the less occasion of punch 4 sizes.
In use, upper clamping plate gas channel 11 links with the compressed air supply line, when stamping-out, does not feed compressed air; After stamping-out finishes, in upper clamping plate gas channel 11, feed compressed air, compressed air enters punch gas channel 41 by upper clamping plate gas channel 11, backing plate gas channel 21 successively, finally the front end face 42 from punch 4 blows out, thereby blows off in the die mouth sticking on product on punch 4 front end faces 42 or waste material.
The above embodiment, it is preferred embodiments of the present utility model, be not to limit practical range of the present utility model, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, all should be included in the utility model patent claim.
