Abstract

The utility model relates to a die, and discloses a material-saving continuous stamping die, which comprises an upper die holder, a male die fixing plate, a lower die holder and a female die fixing plate. The male die fixing plate is fixed onto the upper die holder, the female die fixing plate is fixed onto the lower die holder, male dies are arranged on the male die fixing plate, female dies are arranged on the female die fixing plate, the male dies include a grooving male die, a plurality of stretching male dies and a cutting male die sequentially arranged along a feeding direction, the width of the grooving male die is similar to that of a strip, the stretching male dies are gradually thinned and raised, a grooving female die, a plurality of gradually thinned and raised stretching female dies and a cutting female die are sequentially arranged on the female die fixing plate along the feeding direction, the position of the grooving female die corresponds to that of the grooving male die, the positions of the stretching female dies correspond to those of the gradually thinned and raised stretching male dies, and the position of the cutting female die corresponds to that of the cutting male die. The material-saving continuous stamping die has the advantages that leftover materials can be decreased during machining, and raw materials are saved.

Description

The material-saving continuous stamping die

Technical field

The utility model relates to a kind of mould, especially processes the progressive die that the relief angle material reduces significantly.

Background technology

Often use mould in hardware products processing, one adopts cold-punching mould, as simple punching die, simple blanking die, bending mould, drawing die, composite die, continuous mould etc.Because it is wideer than workpiece that the continuity of processing, billot require, make the leftover pieces after the processing more like this.

The utility model content

For overcoming above-mentioned shortcoming, the utility model purpose is the material-saving continuous stamping die that provides a kind of leftover pieces few.

For achieving the above object, a kind of material-saving continuous stamping die comprises upper bolster, punch retainer, die shoe, die block; Said punch retainer is fixed on the upper bolster, and die block is fixed on the die shoe; Said punch retainer is provided with punch, and die block is provided with die; Said punch comprises the grooving punch close with the billot width that be arranged in order from feedstock direction, thin gradually high polylith stretching convex die and cut-out punch gradually; On the said die block from feedstock direction be provided with successively with the grooving die of grooving punch opposite position, with the gradually thin gradually dark polylith stretching die of thin gradually high polylith stretching convex die opposite position gradually, with the cut-out die that cuts off the punch opposite position.

Concrete, the edge of a knife of said grooving punch is the identical figure edge of a knife slightly little with two close workpiece slits.Thereby with the connection filament between the slit as the attaching parts of all workpiece when the punching press.

Concrete, said is the cylindrical stretching convex die that has punching and shaping near the cylindrical stretching convex die of polylith of cutting off die.

Concrete, be provided with a plurality of alignment pins around the said punch retainer, be provided with a plurality of locating holes that match with alignment pin around the said die block.

More specifically, said alignment pin and locating hole all are six.

Concrete, said ring cutting punch, cylindrical stretching convex die and cut-out punch are embedded on the punch retainer, and said ring cutting die, cylindrical stretching die and cut-out die are embedded on the die block.

The utility model adopts the grooving punch close with the billot width, and the edge of a knife of grooving punch is the identical figure edge of a knife slightly little with two close workpiece slits.Thereby with the connection filament between the slit as the attaching parts of all workpiece when the punching press.The billot that can use the same width with workpiece like this or be slightly wider than the width of the workpiece is as the processing strip, and the width of processing the billot that identical workpiece uses than traditional progressive die has bigger minimizing, thereby has reduced leftover pieces, has saved raw material.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the Workpiece structure sketch map of the utility model processing.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further elaborated.

Material-saving motor case continuous stamping die as shown in Figure 1 comprises upper bolster 2, punch retainer 1, die shoe 4, die block 3; Punch retainer 1 is fixed on the upper bolster 2, and die block 3 is fixed on the die shoe 4; Be inlaid with the grooving punch 101 close that be arranged in order from feedstock direction, the thin gradually high cylindrical stretching convex die 102 of polylith and cut off punch 103 gradually on the punch retainer 1 with billot 5 width; The edge of a knife of grooving punch 101 is the identical figure edge of a knife slightly little with two close workpiece slits; Thereby with the connection filament between the slit as the attaching parts of all workpiece when the punching press; For having the edge of a knife of punching and shaping, be provided with six alignment pins 104 near the cylindrical stretching convex die 102 of the polylith that cuts off punch 103 around the punch retainer 1; Inlay on the die block 3 from feedstock direction be provided with successively with the grooving die 301 of grooving punch 101 opposite positions, with the cylindrical stretching die of the gradually thin gradually dark polylith of thin gradually high cylindrical stretching convex die 102 opposite positions of polylith gradually 302, with the cut-out die 303 that cuts off punch 103 opposite positions, be provided with 6 locating holes 304 that match with alignment pin 104 around the die block 3.

Workpiece like Fig. 2 adopts the mould structure of the utility model to make; Its process is: after band material 5 is sent in the mould, utilize outer rim circular arc limit that the cutting edge of grooving punch 101 goes out workpiece earlier and be connected connection material between two workpiece as wire drawing circular arc limit 501; Along with band material 5 moves forward; Go out workpiece cylinder 502 and workpiece punching 503 gradually by cylindrical stretching convex die 102 then, come from being with to expect to cut off 5 by cutting off the workpiece 504 of punch 103 at last moulding.

More than be that the utility model material-saving continuous stamping die is set forth; Be used for helping to understand the utility model; But the embodiment of the utility model is not restricted to the described embodiments; Anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify, all should be the substitute mode of equivalence, be included within the protection domain of the utility model.
