Description

A kind of crank-guide way punch die new structure

Technical field

The utility model relates to a kind of punch die structure, especially a kind of crank-guide way punch die new structure.

Background technology

What in traditional punch die structure, die was taked with bearing is fixed connection, is exactly that die adopts the form of mold insert to be fixed on bearing with negative clearance value, for preventing becoming flexible, also adds coherent pin; For preventing that die is subject to the effect of cantilever beam shearing force, also need play a supportive role with the form of screw.Although this structure is simple, die is often because of being subject to the large or uneven reason of shearing force to cause die tipping or fracture, and die inconvenience is changed in time, and dimensional accuracy after replacing is also poorer than before, and the life-span of whole punch die is short.Therefore, a kind of new technical scheme of exigence solves above-mentioned technical problem.

Utility model content

The utility model, just for the technical problem existing in prior art, provides simple in structure, easy to operate crank-guide way punch die new structure, and this structure is eliminated die because being subject to the effect of shearing force to cause die tipping or fracture, effectively reduces the scrappage of die; Meanwhile, improved the precision after die is changed, the service life of having improved punch die.

To achieve these goals, the technical solution of the utility model is as follows, and a kind of crank-guide way punch die new structure, is characterized in that, new structure comprises upper bolster, die shoe, punch, die, described die shoe is fixed on bearing, is provided with inner guiding post, outer guiding post between described punch and die, interior guide pin bushing and outer bush, by inner guiding post, outer guiding post, interior guide pin bushing and outer bush are adjusted the relative position of punch and die, even if so frequently change die and also do not affect the service precision of whole punch die.The afterbody of described die offers two symmetrical flat horizontal surfaces, makes the groove of itself and bearing form matched in clearance.Swinging of restriction die.

As a kind of improvement of the present utility model, for collecting together the front and back that prevent die, described die afterbody is installed the second Compress Spring.The front and back position of restriction die under the effect that is not subject to external force.

As a kind of improvement of the present utility model, for ease of regulating the position of inflator crank-guide way, on described die, be inserted in an adjustable ring; In the time that size has error, can directly change adjustable ring.

As a kind of improvement of the present utility model, the bottom, bottom of described die is supported with monoblock V-block, for preventing that die from contacting with the direct of V-block, is encased inside rubber and paves cushioning effect in the V-type groove of V-block.

As a kind of improvement of the present utility model, the top of described die is provided with stripper, prevents that die from tilting along the longitudinal direction, presses down in process and makes it before punch contacts with die at punch, first flatten die, stripper plays discharging effect simultaneously and arrives fixing die effect.

As a kind of improvement of the present utility model, described new structure also comprises the limited block with the conical surface, and described limited block snaps in inflator vat, ensures symmetry requirement.

As a kind of improvement of the present utility model, the connected mode of described die and bearing is floated.

Advantage of the present utility model is as follows, and 1) overall structure is simple, cost is lower, easy to operate; 2) this technical scheme is eliminated die because being subject to the effect of shearing force to cause die tipping or fracture, effectively reduces the scrappage of die; 3) this technical scheme has improved the precision after die replacing, the service life of having improved punch die.

Detailed description of the invention

In order to deepen, to understanding and cognition of the present utility model, below in conjunction with the drawings and specific embodiments, the utility model to be made further instructions and introduced.

embodiment 1:

Referring to Fig. 1, Fig. 2, a kind of crank-guide way punch die new structure, new structure comprises upper bolster 10, die shoe 1, punch 11, die 16, described die shoe 1 is fixed on bearing 17, is provided with inner guiding post 5, outer guiding post 2 between described punch 11 and die 16, interior guide pin bushing 3 and outer bush 4, by inner guiding post 5, outer guiding post 2, interior guide pin bushing 3 and outer bush 4 are adjusted the relative position of punch 11 and die 16, even if so frequently change die and also do not affect the service precision of whole punch die.The afterbody of described die 16 offers two symmetrical flat horizontal surfaces, makes the groove of itself and bearing 17 form matched in clearance, the swinging of restriction die.

embodiment 2:

Referring to Fig. 1, Fig. 2, as a kind of improvement of the present utility model, for collecting together the front and back that prevent die, described die afterbody is installed the second spring 14.The front and back position of restriction die under the effect that is not subject to external force.All the other structures are identical with embodiment 1 with advantage.

embodiment 3:

Referring to Fig. 1, Fig. 2, as a kind of improvement of the present utility model, for ease of regulating the position of inflator crank-guide way, on described die 16, be inserted in an adjustable ring 13; In the time that size has error, can directly change adjustable ring.All the other structures are identical with embodiment 1 with advantage.
