Abstract

The utility model relates to a stamping die, which comprises a convex die (1) and a concave die (2), wherein the concave die (2) is composed of a concave template (3) and two parallel slideway edges (4) which are fixed on the concave template (3) and form a slideway, wherein an upward view shape of the convex die (1) and a vertical view shape of the concave die (2) are shapes which are surrounded by two workpiece end surfaces which need stamping and two parallel slideway edges (4). After the structure is adopted, compared with the prior art, the stamping die has the following advantages that as for the improved stamping die, strip-shaped plates are fed along the slideway in the stamping process, the strip-shaped plates are moved to one direction after once stamping, after the stamping plates are moved for certain distance, the plates need stamping again, the moved distance of the process is decided by the demanded product length, and thereby dies do not need replacing for products with different lengths.

Description

Diel

Technical field

The utility model relates to a kind of diel, specifically is that a kind of punching press width that is applicable to is fixed and the blanking die of the indeclinable weld tabs of length.

Background technology

Existing diel, particularly the punch of weld tabs blanking die and die all are that length dimension is fixing, one secondary mould can only a kind of length dimension of punching press product, want the product of punching press different length size, just need make new mould again, need three kinds of different length of 5cm, 10cm and 20cm as a kind of weld tabs, just need to make three secondary moulds, thereby make the Mold Making cost very big.

The utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, but the diel of a kind of adjustable size multiple length dimension different product of one secondary mould punching press to reduce production costs is provided.

For solving the problems of the technologies described above, the diel that the utility model provides, comprise punch and die, described die is made up of with two the parallel slideway limits that constitute a slideway on being fixed on concave template concave template, and the plan view shape of looking up shape and described die of described punch is the shape that two workpiece end faces that will stamp out slideway limit parallel with two surrounds.

After adopting above structure, the utility model diel compared with prior art has the following advantages:

Diel after the improvement, in punching course, bar shaped sheet material is along the slideway charging, after the punching press, move bar shaped sheet material to a direction, after moving a certain distance, punching press again, the distance that this process moves determines by desired product length, the product of different length like this, just mold exchange more.

As improvement, the plan view shape of looking up shape and described die of described punch is two the grooves by semi arch formation of square block along the center line symmetrical distribution of its left and right directions, this structure embodiment of the present utility model.

As further improvement, be provided with several spacing preiections with horizontal parallel position, slideway limit on the described concave template, this structure can better make bar shaped sheet material move along the slideway direction.

As further improving again, it also comprises the die backing plate, and described die backing plate is arranged under the die, and at least one pleurapophysis of described die backing plate is for outside the die, the part that described die backing plate protrudes in die is provided with chute, and the fluting direction of described chute is laterally parallel with slideway.

The specific embodiment

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

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model diel, comprise punch 1 and die 2, described die 2 is made up of with two the parallel slideway limits 4 that constitute a slideway on being fixed on concave template 3 concave template 3, and the plan view shape of looking up shape and described die 2 of described punch 1 is the shape that two workpiece end faces that will stamp out slideway limit 4 parallel with two surrounds.The plan view shape of looking up shape and described die 2 of described punch 1 is two the grooves 5 by semi arch formation of square block along center line 11 symmetrical distributions of its left and right directions.Be provided with several spacing preiections 6 with 4 horizontal parallel positions, slideway limit on the described concave template 3.It also comprises die backing plate 7, described die backing plate 7 is arranged on die 2 times, at least one pleurapophysis of described die backing plate is for outside the die 2, and the part that described die backing plate 7 protrudes in die 2 is provided with chute 8, and the fluting direction of described chute 8 is laterally parallel with slideway 4.

In punching course, bar shaped sheet material 10 after the punching press, moves bar shaped sheet material 10 to a direction along slideway 4 chargings, after moving a certain distance, and punching press again.The distance that this process moves determines by desired product length, the product of different length like this, just mold exchange more.

The utility model not only is confined to above embodiment, and its concrete structure allows various variations.Such as: the plan view shape of looking up shape and die of punch can change along with the end surface shape of workpiece to be processed, the end face of workpiece to be processed is the triangle of an angle convex, and the plan view shape of looking up shape and die of punch is two the grooves by triangle formation of square block along the center line symmetrical distribution of its left and right directions.In a word, all various variations of being done in the utility model independent claims protection domain are all in protection domain of the present utility model.
