Abstract

The utility model discloses a stamping die capable of regulating the molded surface depth, which comprises a lower drawing terrace die and an upper drawing hollow die. The stamping die capable of regulating the molded surface depth is characterized in that a terrace die insert is overlaid on the top of a terrace die gasket and is connected to the lower drawing terrace die by a bolt and a locating pin; one hollow die insert is overlaid on the bottom of a hollow die gasket and is connected to the upper drawing hollow die by a bolt and a locating pin; and the terrace die gasket and the hollow die gasket can replace the regulation thickness. According to the stamping die capable of regulating the molded surface depth, the problems that the molded surface depth needs to be machined and polished for multiple times, and the precision of the molded surface is difficult to control by the lower drawing terrace die and the upper drawing hollow die can be solved, the quality of parts is guaranteed, and the design is simple to operate, is practical and has low cost.

Description

A kind of diel that can adjust the profile degree of depth

Technical field

The utility model relates to a kind of diel, is specifically related to a kind of diel that can adjust the profile degree of depth.

Background technology

Generally for vehicle body closure member inner panel part; Especially as the required precision of these position profiles of hinge face than higher, draw convex concave mould often need repeatedly processing, polishing just can reach design data require, but this method is difficult to control to upper and lower mould profile processing capacity usually; And repeatedly processing, polishing punch-die are difficult to accurately control to the precision of profile, and pincers worker repairs a die that workload is also big, part status is unstable, bigger to the part quality influence.The problem that this mould exists: processing, processing capacity are difficult to control if need adjustment hinge face, punch-die to need repeatedly.

Summary of the invention

The purpose of the utility model provides a kind of diel that can adjust the profile degree of depth; Can solve the adjustment of the part profile degree of depth and often need repeatedly process, polish die face up and down; And processing capacity and precision problem rambunctious; Promote the stability of part status and the quality of part, simple in structure, with low cost.

The described a kind of diel that can adjust the profile degree of depth of the utility model, draw under comprising punch and on draw die, it is characterized in that:

One punch insert overlap a punch pad above, and be connected down through screw and alignment pin and draw on the punch;

One die plate insert overlap a die pad below, and be connected through screw and alignment pin and draw on the die.

The described a kind of diel that can adjust the profile degree of depth, its described punch pad and die pad can be changed and regulate thickness, promptly prepare to have different punch pad of polylith thickness and die pad.When if the local profile degree of depth need be adjusted behind the part drawing, through adjustment be installed in down draw punch and on draw the spacer thickness in the die plate insert, reach the purpose that changes the die face degree of depth.

The utility model is compared with prior art and is had the following advantages: not only solved the adjustment of the profile degree of depth need to draw under repeatedly processing, the polishing punch and on draw die to the unmanageable problem of the precision of profile, but also guaranteed the part quality quality; This design operation is simple, practical, and is with low cost.

Description of drawings

Fig. 1 is one of structural representation of the utility model (a mould closes state);

Fig. 2 is two (moulds open states) of the structural representation of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Referring to a kind of diel that can adjust the profile degree of depth illustrated in figures 1 and 2, draw under comprising punch 1 with on draw die 2;

One punch insert 3 overlap a punch pad 6 above, and be connected down through screw 7 and alignment pin 8 and draw on the punch 1;

One die plate insert 4 overlap a die pad 5 below, and be connected through screw 7 and alignment pin 8 and draw on the die 2.

Further, described punch pad 6 can be changed with die pad 5 and regulate thickness, promptly prepares to have different punch pad of polylith thickness and die pad.

After changing for ease of the thickness adjusted of punch pad and die pad, convenient processing after punch insert 3 and die plate insert 4 height change, usually punch insert 3 with under draw punch 1 line of demarcation (about two places all be) and be selected in circular arc R corner.This structure applications in the profile required precision than position higher and that the profile height and position often need be adjusted, like the inner plate of car door hinge face.

When the profile degree of depth need rise; Open down draw punch and on draw die after; Through unloading screw and alignment pin punch insert 3 and die plate insert 4 are taken off; Die pad 5 is changed the pad of the thinner pad of a thickness, a thickness thicker of phase counter punch pad 6 replacings, promptly reaches to change the purpose that the profile degree of depth rises.

When the profile degree of depth need descend; Open down draw punch 1 with on to draw die 2 backs logical; Cross unload screw and alignment pin with punch insert 3 take off with die plate insert 4, die pad 5 is changed the pad of a thickness thicker, counter punch pad 6 is changed the thinner pad of a thickness mutually, promptly reach to change the purpose that the profile degree of depth descends.

Claims

1. the diel that can adjust the profile degree of depth, draw under comprising punch (1) and on draw die (2), it is characterized in that:

One punch insert (3) overlap a punch pad (6) above, and be connected down through screw (7) and alignment pin (8) and draw on the punch (1);

One die plate insert (4) overlap a die pad (5) below, and be connected through screw (7) and alignment pin (8) and draw on the die (2).

2. a kind of diel that can adjust the profile degree of depth according to claim 1 is characterized in that: described punch pad (6) and die pad (5) can be changed and regulate thickness.
