Abstract
The utility model discloses a kind of plunger chip die.It comprises drift and die holder, and the top of drift is provided with step protuberance, and step protuberance is arranged with carborundum annulus, die holder offers groove, offers the stepped hole matched with step protuberance in groove, and drift is protruding through stepped hole.Plunger chip die convenient disassembly of the present utility model, to increase the service life.
Description
Technical field
The utility model relates to a kind of field of mechanical die, particularly relates to the plunger chip die of multi-station machine.
Background technology
Multi-station machine is based on the physical dimension of part and shape, and with compared with process sequence automatic production line scheme successively, the advantage of Multi-axis Machining scheme is the whole processing completing part in clamped one time.Except eliminating the clamping time of part between each fixture, process tool also shortens greatly from a station to the traveling time of another station, and these all raise the efficiency with output in play an important role.
Process in written process at multi-station machine, drift bears huge pressure, easily damages, but existing plunger chip die is not quick detachable, causes a whole set of plunger chip die to scrap.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of plunger chip die, this plunger chip die convenient disassembly, increases the service life.
A kind of plunger chip die, comprise drift and die holder, the top of drift is provided with step protuberance, step protuberance is arranged with carborundum annulus, carborundum annulus thickness is 0.5 ~ 2mm, and die holder offers groove, offer the stepped hole matched with step protuberance in groove, drift is protruding through stepped hole.
Carborundum, is commonly called as diamond dust, and its hardness is large, and Mohs' hardness is 9.5 grades, is only second to diamond the hardest in the world; Its anti-wear performance is good, can extend the service life of workpiece, also has excellent toughness and mechanical strength.
Preferably, the bottom of drift is arranged with silicon nitride annulus, and silicon nitride annulus thickness is 1 ~ 3mm, and the lower cross section of drift is rectangle.
Silicon nitride is a kind of important structural ceramic material.It is a kind of superhard material, and itself has lubricity, and wear-resistant, is atomic crystal, but also has excellent impact resistance and mechanical strength.
Preferably, this plunger chip die also comprises connecting portion, and connecting portion is threaded with groove.
Preferably, be provided with polyurethane foam layer between connecting portion and described drift, polyurethane foam layer thickness is 3 ~ 6mm.
Polyurethane foam plastics is that isocyanates and hydroxy compounds are made through polymerization foaming.It has splendid elasticity, flexibility, percentage elongation and compressive strength; Chemical stability is good, resistance to many solvents and oils; High abrasion resistance, comparatively large 20 times of natural sponge; Also having the excellent performance such as processability, thermal insulation, cohesive, is a kind of padded coaming of function admirable.
Compared with prior art, the utility model has following beneficial effect: a kind of plunger chip die of the one that the utility model provides, comprise drift and die holder, the top of drift is provided with step protuberance, step protuberance is arranged with carborundum annulus, die holder offers groove, offers the stepped hole matched with step protuberance in groove, and drift is protruding through stepped hole.Drift and die holder realize quick position and dismounting by step protuberance and stepped hole, carborundum annulus has excellent toughness, wearability and intensity, during punching press, greatly alleviate the wearing and tearing between die holder and drift, carborundum annulus is set on drift, enhance toughness and the impact resistance of drift, make it not fragile, plunger chip die of the present utility model has the advantage of convenient disassembly, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Accompanying drawing indicates as follows: 1-die holder, 2-drift, 3-connecting portion, 4-polyurethane foam layer, 21-silicon nitride annulus, 22-carborundum annulus.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
See Fig. 1, a kind of plunger chip die of the present embodiment, comprise drift 2, die holder 1 and connecting portion 3, the top of drift 2 is provided with step protuberance, step protuberance is arranged with carborundum annulus 22, and carborundum annulus 22 thickness is 0.5 ~ 2mm, die holder 1 offers groove, offer the stepped hole matched with step protuberance in groove, drift 2 is protruding through stepped hole, and connecting portion 3 is threaded with groove.
The present embodiment realizes quick position by stepped hole to drift 2; be threaded by connecting portion 3 and groove and realize fixing; only connecting portion 3 need be first pulled down during dismounting; take out drift 2 again; carborundum annulus 22 has excellent toughness, wearability and intensity; during punching press; greatly alleviate the wearing and tearing between die holder 1 and drift 2; carborundum annulus 22 is set on drift 2; enhance toughness and the impact resistance of drift 2, protection drift 2, prevents drift 2 to be out of shape; make it not fragile, plunger chip die of the present utility model has the advantage of convenient disassembly, long service life.
Preferably, the bottom of drift 2 is arranged with silicon nitride annulus 21, and silicon nitride annulus 21 thickness is 1 ~ 3mm, and the lower cross section of drift 2 is rectangle.During punching press; mainly utilize the top stamped workpieces of drift 2; thus this position is very easily damaged; silicon nitride annulus 21 has that hardness is large, wear-resistant, shock resistance and the good advantage of lubricity; can strengthen the impact resistance of drift 2, wear-resistant and protection drift 2, prevent drift 2 to be out of shape, extend the service life of drift 2.
Preferably, be provided with polyurethane foam layer 4 between connecting portion 3 and described drift 2, polyurethane foam layer 4 thickness is 3 ~ 6mm.Polyurethane foam layer 4 has excellent elasticity and compressive strength, during punching press, can cushion drift 2, the damage greatly to drift 2 during reduction punching press.
Applicant states, the utility model illustrates detailed construction of the present utility model and technique by above-described embodiment, but the utility model is not limited to above-mentioned detailed construction and technique, namely do not mean that the utility model must rely on above-mentioned detailed construction and technique could be implemented.Person of ordinary skill in the field should be understood that; to any improvement of the present utility model; to equivalence replacement and the interpolation of auxiliary element, the concrete way choice etc. of each raw material of the utility model product, all drop within protection domain of the present utility model and open scope.
