Abstract
The utility model relates to a punch device for punching thick materials, in particular to a quickly-replaceable and floating punch device for punching thick materials. By means of the punch device which can be replaced quickly and float relative to male dies, problems of easy fracturing of punches and serious out-of-tolerance hole locations in the part molding process are solved, so that dies are convenient to maintain. The punch device comprises a male die fixing plate, a punch, a discharging plate and a protective sleeve. The punch mounted in the male die fixing plate can float up and down relative to the male die fixing plate, and the protective sleeve for the punch to pass through is arranged in the discharging plate. The punch and the male die fixing plate are in loose transition fit. The quickly-replaceable and floating punch device for punching thick materials is high in practicability and wide in applicable range, and reduces the maintenance cost of dies. By means of the design idea, the service life of dies can be prolonged, so that the porous molding of complicated thick material parts is convenient, qualities of molding parts are reliable, and further, dies are convenient to maintain, and the part cost is reduced.
Description
Technical field:
The utility model relates to a kind of punch device for thick material punching.
Background technology:
In punch die punching forming field, for the material of thickness greater than 6mm, when rushing aperture (the finger-hole footpath is less than the thick hole of twice material) thereon, because complexity and the diversity of moulding material, and the particularity of forming part structure, for forming die structure higher requirement has been proposed.Existing forming technique, with rigidity drift (drift directly is fixed on the punch) and die sheet material to be carried out moulding, often because the forming part hole is many, the position, hole is near and the aperture is little, cause the hole in piece part position that processes overproof, part is the drift frangibility when moulding, gnaw the mould phenomenon and happen occasionally, accessory size can not be guaranteed.The shortcoming of this structure is:
1, product quality is difficult to guarantee, the gradient in hole is large, and precision is lower, and percent defective is high.
2, the mould production cost is high.
3, the Mould Machining precision is low, the drift serious wear, and be not easy to maintenance.
Summary of the invention:
The utility model has solved the overproof serious problem of drift frangibility and position, hole in the forming parts process by adopting a kind of punch device that can be unsteady with respect to the punch quick change, makes mould be convenient to repair.
The utility model is achieved through the following technical solutions:
A kind of thick material stamping-out quick change floating punch device comprises punch retainer, drift, stripper and sheath, and drift is installed in the punch retainer, can fluctuate with respect to punch retainer, and the sheath that passes through for drift is installed in stripper.
It is loose interference fits that drift cooperates with the installation of punch retainer.
The punch retainer lower end has been connected by screw the drift supporting plate.
Punch retainer is comprised of fixed head and quick change nut, and the quick change nut is connected with fixed head by screw thread, and drift is installed in the quick change nut, can fluctuate with respect to the quick change nut.
Quick change nut bottom is with the position that can supply wrench operated.
The utility model is practical, and is applied widely, reduced the maintenance cost of mould.Adopt the utility model mentality of designing, can accomplish to prolong die life, make complicated thick material part porous, shaped convenient, the forming part reliable in quality, and also mould is convenient to repair the reduction cost of parts.
Description of drawings:
Fig. 1 is the punching mould schematic diagram before improving;
Fig. 2 is the mould schematic diagram with quick change drift support board structure;
Fig. 3 is the mould schematic diagram with quick change nut punch structure.
The specific embodiment:
Be illustrated in figure 1 as the punching mould schematic diagram before improving, drift 3 is rigidly connected on the punch by punch retainer 2, and stripper 5 directly contacts with drift 3.
Embodiment 1:
As shown in Figure 2, this device comprises drift supporting plate 4, sheath 6 and drift 3.During the punching moulding, drift supporting plate 4 is connected with punch retainer 2 by screw 1, in order to drift 3 is fixed.6 of sheaths cooperate with stripper 5, because that drift 3 and punch retainer 2 need is gapped, often the matching design with drift 3 and punch retainer 2 is loose interference fits, makes things convenient for drift 3 automatic capturings to pour counterdie.During work, the part of the upper die drives drift 3 and moves down, and under the guiding of sheath 6, drift 3 contacts with plate smoothly exactly, and the cooperating so that whole drift 3 can carry out punch work by floating ground of drift 3 and part of the upper die.
Embodiment 2:
As shown in Figure 3, this device can comprise quick change nut 7, sheath 6 and drift 3.During the punching moulding, quick change nut 7 connects to form punch retainer by screw thread and fixed head 2 ', in order to drift 3 is fixed.6 of sheaths cooperate with stripper 5, because drift 3 is gapped with quick change nut 7, often the matching design with drift 3 and quick change nut 7 is loose interference fits, makes things convenient for drift 3 automatic capturings to pour counterdie.During work, the part of the upper die drives drift 3 and moves down, and under the guiding of sheath 6, drift 3 contacts with plate smoothly exactly, and the cooperating so that whole drift 3 can carry out punch work by floating ground of drift 3 and part of the upper die.In order to make things convenient for the replacing of quick change nut 7, being designed with in the lower end of quick change nut 7 can be for the part of spanner 8 operations.
The utility model has been taked a kind of new mentality of designing, being about to the drift floating principle combines with traditional punching forming technique, improve at mould, original rigidity drift is improved to the quick change drift that floats, because easily and the counterdie centering, improved positional precision and the drift rigidity of drift and die hole when the quick change drift that floats is convenient to maintain and replace drift and work, therefore overcome and gnawed the mould phenomenon, reduced manufacturing cost.And mould employing rapid changing mechanism, be convenient to maintenance, can reduce the power consumption of lathe, kinematic accuracy is high, and wearing and tearing are few, and drift is convenient to automatic capturing because of floating principle and is poured counterdie.
