Description

A kind of diel for the manufacture of expansion piece

Technical field

The utility model relates to a kind of diel, is specifically related to a kind of diel for the manufacture of expansion piece.

Background technology

Material (metal or nonmetal), in Cold Press Working, is processed into a kind of special process equipment of part (or semi-finished product), is called cold punching die (being commonly called as cold-punching mould) by stamping die.Punching press is at room temperature, utilizes the mould be arranged on forcing press to apply pressure to material, makes it produce separation or plastic deformation, thus obtains a kind of pressure processing method of required part.Progressive die (also claiming the progressive die), on the feeding direction of blank, has two or more station, in the one stroke of forcing press, different stations successively completes the mould of twice or the above stamping procedure of twice.

And in prior art expansion piece due to structure comparatively complicated, thus mostly single die is adopted, by expansion piece through too much journey operation, need to use welding when even assembling expansion piece, thus also need will to need corresponding diel now simultaneously for this reason, realize the continuous automatic production processing of this product, thus enhance productivity.

Utility model content

For the deficiency that prior art exists, it is simple, easy to use that the purpose of this utility model is to provide a kind of structure, the diel for the manufacture of expansion piece that efficiency is high.

For achieving the above object, the utility model provides following technical scheme: a kind of diel for the manufacture of expansion piece, comprise upper bolster and die shoe, described upper bolster is provided with upper module, described die shoe is provided with lower module, described lower module comprises the first punching concave die from left to right, second piercing punch, first trim die, second trim die, 3rd punching concave die, and the die-cut die of blanking, described upper module and described lower module match, comprise the first piercing punch from left to right, second punching concave die, first trimming punch, second trimming punch, 3rd piercing punch and the die-cut punch of blanking.

Of the present utility modelly to be set to further: described first punching concave die is provided with countersunk head square hole and semicircle orifice.

Of the present utility modelly to be set to further: described second piercing punch is provided with two parallel bar shaped projections and is positioned at the triangle convex at two ends, described second piercing punch is also provided with location square hole, and the hole that the hole that described location square hole is formed and countersunk head square hole are formed is communicated with.

Of the present utility modelly to be set to further: the second square groove that described first trim die comprises the first bar-shaped trough and is communicated with the first bar-shaped trough.

The utility model has following advantage: compared to prior art, can to the processing of expansion piece, and can control accuracy accurately, and single product is one time punching molded in same beat, is applicable to the progressive stamping operation of this product production line.At the saving energy, while reducing costs, improve production efficiency greatly.

Detailed description of the invention

Referring to figs. 1 through Fig. 4, the utility model embodiment is described further.

A kind of diel for the manufacture of expansion piece, comprise upper bolster 1 and die shoe 2, described upper bolster 1 is provided with upper module 3, described die shoe 2 is provided with lower module 4, described lower module 4 comprises all symmetrically arranged first punching concave die 5 from left to right, second piercing punch 6, first trim die 7, second trim die 8, 3rd punching concave die 9, and the die-cut die 10 of blanking, shaping for impacting, upper module 3 and lower module 4 match simultaneously, comprise the first piercing punch 11 from left to right, second punching concave die 12, first trimming punch 13, second trimming punch 23, 3rd piercing punch 14 and the die-cut punch 15 of blanking.

The semicircle orifice 17 that symmetrically arranged first punching concave die 5 is provided with follow-up need triangle convex 19 extrude before, first get through hole, be conducive in subsequent handling for facilitating punching press, not easily bulk deformation, second piercing punch 6 is also provided with two parallel bar shaped projections 19 for extruded product, on the second piercing punch 6, be also provided with location square hole 20, the hole that location square hole 20 is formed is communicated with the hole that countersunk head square hole 20 is formed, and forms the shape needed for an expansion piece simultaneously.

The second square groove 22 that first trim die 7 comprises the first bar-shaped trough 21 and is communicated with the first bar-shaped trough 21, can the both sides of stamping products, and the second trim die 8 by the punching press of product two ends out, finally can form single product simultaneously.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
