Description

A kind of punching press plate forming device with arc detent mechanism
Technical field
The utility model belongs to punching press plate forming device technical field, more particularly to a kind of rushing with arc detent mechanism Pressing plate shaped device.
Background technology
At present, in punch forming, the actual working state of mould, plate position in a mold and mold component press chapter Precision is all that detent mechanism is to determine the device of the relative position of plate and mould parts an important factor for influenceing press work, Ensure the strength member being smoothed out in punching course, prior art has the stamping parts for big rise and fall due to easily producing Uncontrollable play, it is impossible to accurate and stable positioning, the problem of so as to cause the quality for influenceing to stretch.
The content of the invention
The utility model provides a kind of punching press plate forming device with arc detent mechanism, to solve above-mentioned background technology In propose prior art and the stamping parts for big rise and fall be present due to easily producing uncontrollable play, it is impossible to it is accurate and steady Fixed positioning, so as to cause influence stretch quality the problem of.
The technical problem that the utility model solves is realized using following technical scheme:One kind has arc detent mechanism Punching press plate forming device, including the arc detent mechanism being respectively arranged on the blank holder of mould installion platform both sides is described The cambered surface of the striker plate of arc detent mechanism limits the two side ends for being contacted with plate respectively, and the surface of plate one connects recessed Mould, the punch-pin of its another surface connection, the plate is under Gravitative Loads, the chamfering back skating of the arc detent mechanism through two side ends In the workspace that two cambered surfaces limit, through punch-pin and cavity plate, common crimping acts on shaping up and down.
Further, the cavity plate is arranged above plate upper surface.
Further, the punch-pin is arranged at below plate lower surface.
Advantageous effects:
1st, this patent limits the two side ends for being contacted with plate respectively using the cambered surface of the striker plate of the arc detent mechanism, The cavity plate of the surface of plate one connection, the punch-pin of its another surface connection, the plate is under Gravitative Loads, through two side ends The chamfering back skating of arc detent mechanism in the workspace that two cambered surfaces limit, through punch-pin and cavity plate up and down common crimping effect into Type, because during stretching and punching, when mould molds, plate is placed on blank holder, and the arc on blank holder is determined Plate is introduced working region by position mechanism, and plate is placed on punch-pin, and under self gravitation effect, both ends collapse downwards plate, Into the working region of arc detent mechanism, the slide guide face of the backgauge face upper end of arc detent mechanism can arrive the material side for ensureing plate Smoothly enter backgauge face control range, after drawing and forming starts, punch-pin closes in cavity plate and blank holder, punch-pin push down plate to Lower movement, in the process, the material side of plate equivalent on punch-pin fixed point move in a circle and be consistent, so entirely drawing During stretching, plate contacts with arc detent mechanism all the time, and plate is unanimously in spacing state, without play occurs, increases The strong stability of the positioning of plate, improves stamping parts quality.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the punching press plate forming device with arc detent mechanism of the utility model.
Embodiment
The utility model is described further below in conjunction with accompanying drawing:
In figure:1- blank holders, 2- arc detent mechanisms, 3- striker plates, 4- cambered surfaces, 5- plates, 6- cavity plates, 7- punch-pin.
Embodiment:
The present embodiment:As shown in figure 1, a kind of punching press plate forming device with arc detent mechanism 2, including install respectively Arc detent mechanism 2 on the blank holder 1 of mould installion platform both sides, the cambered surface of the striker plate 3 of the arc detent mechanism 2 4 limit the two side ends for being contacted with plate 5, the cavity plate 6 of the surface of plate 5 one connection, the punch-pin of its another surface connection respectively 7, the plate 5 is under Gravitative Loads, work that the chamfering back skating of the arc detent mechanism 2 through two side ends limits in two cambered surfaces 4 In area, shaping is acted on through the crimping common about 6 of punch-pin 7 and cavity plate.
The cavity plate 6 is arranged above the upper surface of plate 5.
The punch-pin 7 is arranged at below the lower surface of plate 5.
Operation principle:
This patent limits the two side ends for being contacted with plate, institute by the cambered surface of the striker plate of the arc detent mechanism respectively The cavity plate of the surface of plate one connection is stated, the punch-pin of its another surface connection, the plate is under Gravitative Loads, the arc through two side ends The chamfering back skating of shape detent mechanism in the workspace that two cambered surfaces limit, through punch-pin and cavity plate up and down common crimping effect into Type, because during stretching and punching, when mould molds, plate is placed on blank holder, and the arc on blank holder is determined Plate is introduced working region by position mechanism, and plate is bred on punch-pin, and under self gravitation effect, both ends collapse downwards plate, Into the working region of arc detent mechanism, the slide guide face of the backgauge face upper end of arc detent mechanism can arrive the material side for ensureing plate Smoothly enter backgauge face control range, after drawing and forming starts, punch-pin closes in cavity plate and blank holder, punch-pin push down plate to Lower movement, in the process, the material side of plate equivalent on punch-pin fixed point move in a circle and be consistent, so entirely drawing During stretching, plate contacts with arc detent mechanism all the time, and plate is unanimously in spacing state, without play occurs, this Utility model solves prior art and the stamping parts for big rise and fall be present due to easily producing uncontrollable play, it is impossible to accurate Really and stable positioning, so as to cause the quality for influenceing to stretch the problem of, there is the stability for the positioning for enhancing plate, improve The advantageous effects of stamping parts quality.
Using the technical solution of the utility model, or those skilled in the art is in the inspiration of technical solutions of the utility model Under, similar technical scheme is designed, and reach above-mentioned technique effect, it is to fall into the scope of protection of the utility model.
