Description

A kind of automatic drawing back device of intermittent pressing forming terrace die
Technical field
The utility model is related to a kind of Tool and Die Technology, and in particular to a kind of automatic drawing back dress of intermittent pressing forming terrace die Put.
Background technology
In recent years, high-accuracy progressive die blanking die has been widely used in various industries.Progressive die stamping parts is produced Product are complicated, and changing features are various, so stamping products part punching or formed features need batch (-type) punching press, to meet The feature requirement of product.Usually, common batch (-type) punching press punch structure is as shown in figure 1, it is main by upper padding plate 1 ', pumping board Sliding block 2 ', pumping board annex 3 ', punch-pin 4 ', screw 5 ', punch-pin briquetting 6 ', punch retainer 7 ' and push rod 8 ' are constituted.The push rod 8 ' are located at pumping board sliding block 2 ' in the mounting groove of upper padding plate 1 ', and the connection pumping board of push rod 8 ' sliding block 2 ', pass through cylinder-driven control Pumping board sliding block moves forward and backward;The pumping board annex 3 ' and punch-pin 4 ' are located in punch retainer 7 ', pumping board annex 3 ' and punch-pin 4 ' are interfixed, and the punch-pin briquetting 6 ' is fixed on punch retainer 7 ' by screw 5 ', limitation pumping board annex 3 ' and punch-pin 4 ' move downward.
Common batch (-type) punching press punch-pin utilizes the wedge mechanism work of pumping board sliding block and pumping board annex, the work shape of punch-pin State is relatively stable;But when needing intermittent pressing, pumping board sliding block retreat, now punch-pin and pumping board annex can not automatically retract, it is necessary to Returned after being come in contact with plate by plate top, be so likely to result in plate plane and deform or rush by mistake, so that punching press Part product quality is unqualified.
Utility model content
There is provided a kind of automatic receipts of batch (-type) punching press punch-pin for the defect that the purpose of this utility model is for prior art Return device, so that in intermittent pressing, pumping board annex and punch-pin can be automatically retracted, it is to avoid rush situation appearance by mistake.
Realize that the technical scheme that the utility model purpose is used is as follows:A kind of automatic drawing back dress of intermittent pressing forming terrace die Put, including upper padding plate, pumping board sliding block, pumping board annex, spring, punch-pin, screw, punch-pin briquetting, punch retainer and push rod, its body Levy and be:
Push rod and the pumping board sliding block is located in the mounting groove of upper padding plate, and push rod connection pumping board sliding block, and push rod passes through gas Cylinder is promoted, so as to control moving forward and backward for pumping board sliding block;The pumping board annex and punch-pin are located in punch retainer, and pumping board is attached Part and punch-pin interfix;Spring standing groove is provided with pumping board annex, spring is arranged at spring standing groove, the axis direction of spring It is parallel with the direction of motion of punch-pin;Punch-pin briquetting is fixed on punch retainer by screw.
Further, push rod promotes pumping board sliding block to travel forward, and under wedge structure effect, pumping board annex and punch-pin are downward Motion, spring-compressed.
Further, when needing intermittent pressing, push rod promotes pumping board sliding block to move backward, and spring recovers elongation state, Pumping board annex is moved upwards with punch-pin under the elastic force effect of spring, and punch-pin automatically resets.
Beneficial effect, the utility model utilizes the release for the spring force being located in punch-pin annex so that pumping board sliding block exists In fallback procedures, pumping board annex and punch-pin can be automatically retracted, so as to be prevented effectively from above mentioned problem appearance.
Brief description of the drawings
Fig. 1 is existing batch (-type) punching press punch-pin structural scheme of mechanism;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is use state schematic diagram of the present utility model;
Embodiment
The technical solution of the utility model is described in detail below in conjunction with accompanying drawing 2-3.
As Figure 2-3, the utility model provide batch (-type) punching press punch-pin mechanism, including upper padding plate 1, pumping board sliding block 2, Pumping board annex 3, spring 4, punch-pin 5, screw 6, punch-pin briquetting 7, punch retainer 8 and push rod 9.
The push rod 9 and pumping board sliding block 2 are located in the mounting groove of upper padding plate 1, and the connection pumping board of push rod 9 sliding block 2, by pushing away Bar 9 is promoted by cylinder, and then controls moving forward and backward for pumping board sliding block 2;The pumping board annex 3 and punch-pin 5 are solid positioned at punch-pin In fixed board 8, pumping board annex 3 and punch-pin 5 interfix.Spring standing groove is provided with pumping board annex 3, it is attached that spring 4 is arranged at pumping board The spring standing groove of part 3, axle of spring direction is parallel with the direction of motion of punch-pin 5.Punch-pin briquetting 7 is fixed on convex by screw 6 In mould fixed plate 8.The pumping board annex and punch-pin are located in punch retainer.
When punch-pin is in running order, push rod 9 promotes pumping board sliding block 2 to travel forward by cylinder, now in wedge shape knot Under structure effect, pumping board annex 3 is moved downward with punch-pin 5, and spring 4 compresses under the restriction of punch-pin briquetting 7;
When needing intermittent pressing, push rod 9 promotes pumping board sliding block 2 to move backward, and now wedge structure fails, and spring 4 is extensive Multiple elongation state, pumping board annex 3 is moved upwards with punch-pin 5 under the elastic force effect of spring 4, so as to realize the automatic multiple of punch-pin Position.Big arrow direction indication is not annotated in Fig. 2-3 for the pumping board direction of motion.
Although principle of the present utility model is described in detail above in conjunction with preferred embodiment of the present utility model, It should be appreciated by those skilled in the art that above-described embodiment is only the explanation to exemplary implementation of the present utility model, and The non-restriction to the utility model scope.Details in embodiment does not constitute the limitation to the utility model scope, In the case of without departing substantially from spirit and scope of the present utility model, any equivalent transformation based on technical solutions of the utility model, letter Single replacement etc. is obvious to be changed, and is all fallen within the utility model protection domain.
