Abstract

The utility model discloses an adjustable positioning device which comprises a support, a positioning block and a tension spring, wherein the positioning block is hinged to the support, the support and the positioning block are connected with the two ends of the tension spring respectively, the two ends of the tension spring are mounted on the support and the positioning block through pins respectively, a groove is formed in one end of each pin in the outer diameter direction, and tension buckles of the tension spring are buckled on the grooves in a sleeved mode. Due to the fact that the tension buckles of the tension spring are buckled on the grooves in the sleeved mode, the tension spring is convenient to detach and replace. The positioning block can be adapted to the downward-pressing height of a blank automatically through the stretching of the tension spring so that the blank can be placed steadily, the instability of product positioning of an original bevel placing type single-side positioning structure is overcome, positioning of the blank in the molding process is guaranteed, production efficiency is improved greatly, and the manufacturing cost of an original parting line lock is saved.

Description

A kind of adjustable positioning device
Technical field
The utility model relates to punch forming positioning equipment, particularly a kind of adjustable positioning device.
Background technology
In general molding structure, be all to adopt pipe position to guarantee the stamping quality of product, still for the uncertain factor of some stocks, pipe position needs manual adjustments aborning, will reduce production efficiency.Manage the manufacturing cost that has also increased to a certain extent mould that is arranged on of position.Particularly, for the product to arc lower drawing and forming class, due to structural specificity, its monolateral location structure is very poor to the stability of product stock location.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of can automatically adjusting to adapt to stock placement and the strong adjustable positioning device of stability thereof.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of adjustable positioning device, comprise support, locating piece and extension spring, and this locating piece is hinged on this support, and the two ends of this extension spring connect respectively this support and locating piece.
In technique scheme, the two ends of extension spring are arranged on this support and locating piece by pin respectively.
In technique scheme, one end of pin is provided with groove along external diameter direction, and the pulling buckle cover of this extension spring is buckled on this groove.The pulling buckle cover of extension spring is buckled on this groove, replacing extension spring for convenience detach.
In technique scheme, locating piece is arranged on this support by rotating shaft.Use rotating shaft is convenient for changing.
In technique scheme, be provided with a pressure pin on support, support locating piece.The slewing area of restriction locating piece, can arbitrarily not rotate locating piece.
The beneficial effects of the utility model are: locating piece adapts to the height pressing down of stock automatically by the stretching of extension spring, stock can be placed reposefully, overcome and along inclined-plane, placed the unstability of monolateral location structure to product orientation originally, guarantee the location of stock in forming process, greatly enhance productivity.Save the manufacturing cost of original pipe position.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model side.
In figure, 1, support; 2, locating piece; 3, extension spring; 4, pin; 5, rotating shaft; 6, pressure pin.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of adjustable positioning device, is arranged on a side or the both sides of counterdie, for support and automatically regulate stock, comprises support 1, locating piece 2 and extension spring 3.This support 1 locking is in the frame of mould.Locating piece 2 is arranged on support 1 top rotationally by rotating shaft 5, the outstanding support 1 of the fixed front end to piece, for retainer portion, the tail end of locating piece 2 is equipped with a pin 4, one end of this pin 4 locating piece of giving prominence to 2 is provided with the groove arranging along external diameter direction, and the pulling buckle cover of extension spring 3 one end is buckled in this groove, is positioned on the support 1 of locating piece 2 belows and is equipped with another pin 4, the bared end of same this pin 4 is provided with the groove arranging along external diameter direction, and the pulling buckle cover of extension spring 3 other ends is buckled in this groove.In support 1, be equipped with a pressure pin 6, this bottom that pressure pin 6 is outstanding and just jacking this locating piece 2, the position that this pressure pin 6 is depended on is between rotating shaft 5 and pin 4, this design is in order to limit the slewing area of locating piece 2, guarantee the horizontal stability of locating piece 2, at stock, complete after moulding, stock no longer acts on fixed on piece, prevent because the convergent force of spring makes locating piece 2 rotate toward the outside of mould, and turn to the position not contacting with stock, keep the retainer portion of locating piece 2 can return to original location status, the stability of stock location is improved, while is improving production efficiency also.Be all applicable for the monolateral or product of bilateral moulding, and effect is fine.
Operation principle of the present utility model, stock is placed on counterdie, the retainer portion of locating piece 2 front ends is being pressed at the edge of stock, in the process of the downward die stamping of patrix, down, locating piece 2 is subject to down rotating after downward pulling force in the retainer portion that locating piece 2 is being pressed at the edge of stock, extension spring 3 stretches simultaneously, due to the effect of extension spring 3 convergent forces, make the retainer portion of locating piece 2 have support force upwards, the edge of stock can be moved down reposefully in the process to compacted under; After locating piece 2 turns to a certain degree to mould inner side, just avoid the edge of stock, the edge of stock is because the relation of drawing and forming is also received toward mould inner side, stock departs from locating piece 2, after locating piece 2 is subject to the active force of extension spring 3, counter rotation is moving, due to the effect of pressure pin 6, makes locating piece 2 rotate horizontal levels and makes just to stop operating, keep always, until next piece stock is placed into counterdie, carry out punching press next time.
Above embodiment is just explanation rather than restriction the utility model, and the equivalence of doing according to the method described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
