Description

General shearing die

Technical field

The utility model relates to tooling device technical field, refers to a kind of general shearing die particularly, for shearing coil feed line.

Background technology

Press workshop coil feed line use usually general shearing die shear body of a motor car part coiled strip, shearing scope comprises Little Caesar, B07 series, F91A is serial, A08 is serial, the straight line class part of the serial vehicle of F91G, shear material thick scope be the plate of 0.6-1.0mm, this general shearing die annual production reaches about 1,000,000, is the important mould that coil feed line uses.

At present, usual die trimming punch-die is one side cutting edge, and insert is vertically fixed on insert base by screw, if need after the wearing and tearing of deburring punch-die insert insert welding bedding-in or copy, the repairing time is long, affects production efficiency.In addition, cannot adjust the gap between deburring punch and deburring die after deburring punch-die insert serious wear, again must copy insert, maintenance cost is higher.

Summary of the invention

The general shearing die that the utility model object is to overcome above-mentioned the deficiencies in the prior art and provides a kind of structure simple, easy to use.

The technical scheme realizing the employing of the utility model object is: a kind of general shearing die, comprise deburring punch and deburring die, it is characterized in that: described deburring punch comprises the punch base being provided with the first punch retaining thread hole, be provided with punch insert and the punch hold-down screw of punch cutting edge, described punch insert is rectangular structure, described punch cutting edge totally four and lay respectively at four long limits of two corresponding long side surfaces, described punch insert is also provided with the second punch retaining thread hole be communicated with the first punch retaining thread hole, described punch insert is fixed on punch base by punch hold-down screw and the first punch retaining thread hole and the second punch retaining thread hole, described deburring die comprises the die base being provided with the first die retaining thread hole, the die plate insert being provided with cutting edge of die and die hold-down screw, described die plate insert is rectangular structure, described cutting edge of die totally four and lay respectively at four long limits of two corresponding long side surfaces, described die plate insert is also provided with the second die retaining thread hole be communicated with the first die retaining thread hole, and described die plate insert is fixed on die base by die hold-down screw and the first die retaining thread hole and the second die retaining thread hole.

Pad is equipped with between described punch insert and punch base and between die plate insert and die base.

The utility model structure is simple, after cutting edge wearing and tearing of punch insert or die plate insert, the direction of punch insert or die plate insert can be changed, be adjusted to another new cutting edge to use, meanwhile, when after punch insert or die plate insert wearing and tearing, by setting up between punch insert and the first base, and the pad between die plate insert and the second base regulates the distance between punch insert and die plate insert, reduce maintenance cost and reduce maintenance time and downtime.

Fig. 2 is punch insert structural representation.

Fig. 3 is working state schematic representation of the present utility model.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Figure 1, the general shearing die of the utility model comprises deburring punch 1 and deburring die 2, and wherein, deburring punch 1 comprises the first base 1.1, punch insert 1.2 and the first hold-down screw (not shown); Deburring die 2 comprises the second base 2.1, die plate insert 2.2 and the second hold-down screw (not shown).

Punch insert 1.2 in the utility model is identical with the structure of die plate insert 2.2, the present embodiment is described for punch insert 1.2, as shown in Figure 2, punch insert 1.2 is rectangular structure, punch insert 1.2 is along the four edges (1.2.2 of length direction, 1.2.3,1.2.4,1.2.5) be cutting edge, punch insert 1.2 has the first retaining thread hole 1.2.1 along cross direction, and punch insert 1.2 is fixed on the first base 1.1 by the first retaining thread hole 1.2.1 by the first hold-down screw.

First base 1.1 of the present utility model is arranged on punch base plate 3, and the second base 2.1 is arranged on die base plate 4.Coiled strip moves to deburring punch 1 surface of mould with line unwinding equipment, deburring die 2 moves downward with equipment slide block, and die holding pad 5 first pushes down plate, and the die plate insert 2.2 of deburring die 2 cuts punch insert 1.2 subsequently, after moving to certain distance, plate cutting is completed.Deburring die 2 moves upward with equipment slide block subsequently.

Because cutting edge is easily worn, the punch insert 1.2 therefore in the utility model and die plate insert 2.2 all adopt four cutting edges, can change use, improve die life and formation efficiency.

When punch insert 1.2 or die plate insert 2.2 wear and tear comparatively seriously, can between punch insert 1.2 and the first base 1.1, and between die plate insert 2.2 and the second base 2.1, all pad is set, to regulate the gap between punch-die, reduce maintenance cost and reduce maintenance time and downtime.
