Abstract
The utility model discloses a forming punch combination device, which comprises a punch (1), a punch sleeve (2) and connecting threads (3). The punch (1) comprises a stamping portion (11), a guiding portion (12) and a locking portion (13). The diameter of the guiding portion (12) is smaller than that of the locking portion (13). The punch sleeve (2) is provided with a guiding hole (22) and a locking hole (23) matched with the guiding portion (12) and the locking portion (13) respectively. One end of the locking hole (23) away from the guiding hole (22) is provided with an inner thread (25). The connecting threads (3) comprise a matching portion (31) threaded with the guiding hole (22) and a thread connecting portion (32) connected with a punching machine. A pressing portion (35) for pressing the punch (1) is arranged outside the matching portion (31). When a workpiece wraps the punch, the forming punch combination device can separate the workpiece and the punch conveniently and is stable in punching during a punching process.
Description
Technical field
The utility model relates to a kind of decompressor, particularly relates to a kind of moulding towards composite set.
Background technology
In the prior art, during stamped workpieces, drift is made and finished product workpiece corresponding shape, drift is fixedly connected with punch press, and drift makes blank after pouring workpiece.But, receiving the influence of Sheet Metal Forming Technology and workpiece surface roughness, workpiece encases drift easily, makes drift can't extract workpiece smoothly, and this has had a strong impact on the efficient of punching press.
Therefore those skilled in the art are devoted to develop the decompressor that a kind of drift can be extracted workpiece smoothly.
The utility model content
Because the above-mentioned defective of prior art, the utility model technical problem to be solved provides the decompressor that a kind of drift can be extracted workpiece smoothly.
For realizing above-mentioned purpose, the utility model provides a kind of moulding towards composite set, comprises drift, dashes cover and connects spiral shell; Said drift comprises pressing part, guide part and tight lock part; The diameter of said guide part is less than the diameter of said tight lock part; The said cover that dashes is provided with the pilot hole and the locking hole that can cooperate with said guide part and tight lock part respectively; Said locking hole is provided with internal thread away from said pilot hole one end; The said spiral shell that connects comprises the auxiliary section that is threaded with said pilot hole, and the threaded joints that can be connected with punch press; The arranged outside of said auxiliary section is useful on the press-fit portion that compresses said drift.
Adopt the combinations thereof device, will connect spiral shell and be fixedly connected with punch press, the startup punch press makes to connect spiral shell and prop up drift, thereby drift is poured in the workpiece.After punching press finishes,, the guide part diameter of drift can drift be extracted workpiece because, therefore dashing cover less than the diameter of tight lock part; If the situation that drift is encased by workpiece occurs, can keep certain interval owing to dash between cover and the workpiece, therefore can adopt striker plate that workpiece is separated with drift.
More steady for making drift and connecing the spiral shell power transmission, said drift is positioned at the said end that dashes cover one side and is provided with cone boss; The said spiral shell that connects is provided with the taper hole that can cooperate with said cone boss.
Connect spiral shell and better drive and dash the cover motion for making, and make and connect spiral shell and dash can the bigger stamping press of transmission between overlapping, be wholely set the thrust boss between said auxiliary section that connects spiral shell and the threaded joints; Said thrust boss and the said end face that dashes cover are fitted each other.
Produce gas when overlapping with the drift relative motion for avoiding dashing and impact, the said locking hole that overlaps that dashes is disposed radially steam vent.
Produce gas when further avoiding dashing cover and impact, in the said locking hole, be positioned at said internal thread and be provided with air discharge duct near the tail end of said pilot hole with the drift relative motion.
The beneficial effect of the utility model is: when workpiece encased drift, the utility model can easily separate workpiece with drift, and in punching course, punching press is steady.
Description of drawings
Fig. 1 is the structural representation of the utility model one specific embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
As shown in Figure 1, a kind of moulding comprises drift 1, dashes cover 2 and connects spiral shell 3 towards composite set.
Connect spiral shell 3 and comprise the auxiliary section 31 that is threaded with pilot hole 22, and the threaded joints 32 that can be connected with punch press, the arranged outside of auxiliary section 31 is useful on the press-fit portion 35 that compresses drift 1.Connect between auxiliary section 31 and the threaded joints 32 of spiral shell 3 and be wholely set thrust boss 33, thrust boss 33 is fitted with the end face that dashes cover 2 each other.
Drift 1 is positioned at the end that dashes cover 2 and is provided with cone boss 14, connects spiral shell 3 and is provided with the taper hole 34 that can cooperate with cone boss 14.
When moulding is worked towards composite set, the threaded joints that connects spiral shell 3 32 is fixedly connected with the punch press (not shown), starts punch press, make to connect spiral shell 3 and drive and dash cover 2 and drift 1 to workpiece 4 motions.When drift 1 props up workpiece 4, connect spiral shell 3 and continue to drive and dash cover 2 to workpiece motion s, at this moment, dash cover 2 relative drifts 1 and move, cooperate fully each other with the taper hole that connects spiral shell 3 34 up to the cone boss 14 of drift 1, and even at the cost of one's life.Connect spiral shell 3 and continue under the active force of punch press, to move, therefore connect spiral shell 3 drift 1 is poured in the workpiece 4, accomplish processing to workpiece 4.After punching press finishes, connect spiral shell 3 and drive and dash cover 2, dash cover 2 and keep relative motion, move to the junction of the pilot hole 22 that dashes cover 2 and locking hole 23 up to the tight lock part 13 of drift 1 with drift 1 away from workpiece 4 motions.Because, therefore dashing cover 2 less than the diameter of tight lock part 13, guide part 12 diameters of drift 1 can drift 1 be extracted workpiece 4; If the situation that drift 1 is encased by workpiece 4 occurs, kept certain interval owing to dash between cover 2 and the workpiece, therefore can adopt striker plate 5 that workpiece 4 is separated with drift 1.
More than describe the preferred embodiment of the utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technical staff in the art according to the design of the utility model on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in determined protection domain by claims.
