Abstract
The invention relates to a guide structure for fine blanking die sets. The guide structure comprises an upper die base, a lower die base, a guide bush, a bushing, a guide pillar, a flange and a screw, the guide pillar is in taper fit with the inner surface of the bushing, and the guide pillar and the lower end face of the bushing are mutually fixed through the screw and the flange. The guide structure is beneficial to mounting of dies and sharpening of die points, service life of the dies is prolonged, and working is safe and reliable. In the adopted guide structure for the fine blanking die sets, a press-in end of the guide bush is identical to an outer cylindrical surface of a guide end in diameter, the surface of the guide sleeve is free of steps and tool withdrawal grooves, and accordingly the guide structure is easy to process and mount and firm, and the guide bush is good in quality and capable of guaranteeing excellent guide precision.
Description
Technical field
The present invention relates to a kind of automobile die, relate in particular to a kind of guide frame of Fine punching die frame.
Background technology
Guider is the important composition parts in Fine punching die frame, and it has referred to install the kinematic pair that mainly is comprised of parts such as guide pin bushing, guide pillars on upper and lower die holder.Under the constraint of guider, during upper and lower mould relative motion, move along a correct direction all the time, thereby reach the purpose of precision stamping.
The guide pillar of tradition Fine punching die frame and the installation of die shoe, major part is with the fixing coupling method of straight hole interference fit, guide pin bushing is different with the external cylindrical surface diameter of guide end at pressure people's end in die holder hole, presses the people to hold cylindrical less than the guide end cylindrical, forms two cylindricals of step.Although this kind connection scheme has the convenient advantage of making, but, because mould is the rapid wear instrument, so for the precision that guarantees mould often need to be keeped in repair mould, change guide pillar, guide pin bushing are installed, maintenance and installation mold be inconvenience very, and also be not easy to the precision that keeps higher after the dismounting again of mould, the pressure people of guide pin bushing end is different with guide end external cylindrical surface diameter simultaneously, form step on the surface, there is darker escape at its interface, easily cracks after increase difficulty of processing and heat treatment, affects the guide pin bushing quality.
Some adopts a kind of detachable guide pillar, through the prior art literature search is found, Chinese patent application number is the patent of 200820083071 .2, denomination of invention is: a kind of detachable guide pole die carrier, this new patent provides a kind of detachable guide pole die carrier, guide pillar is connected by screw with lining, lining is connected by screw with lower mold holder, can movablely dismantle guide pillar, but also has following deficiency: at first, because lining adopts screw attachment, make the coaxiality error in guide pillar and die shoe hole larger, locate inaccuracy, affect the operating accuracy of fine blanking die.Secondly, because lining adopts screw attachment, because forcing press vibration in punching course causes screw loosening, guide pillar and die shoe are broken away from, cause the accident.Again, because lining adopts screw attachment, to open some screwed holes on the flange of lining, must make the oversize of lining, cause the space that punch and matrix is installed to diminish.
Summary of the invention
The present invention for overcome the above problems provide a kind of simple in structure, improve punching precision, extend the guide frame of the Fine punching die frame of die life.
Technical scheme of the present invention is: comprising upper bolster, die shoe, guide pin bushing, lining, guide pillar, flange and screw, is taper fit between the inner surface of described guide pillar and lining, fixes by screw and flange between guide pillar and lining lower surface.
Described sleeve outer surface is cylindrically to match with the hole on die shoe.
Described sleeve outer surface is coniform.
Described guide pin bushing outer surface is cylindrical, matches with the hole on upper bolster.
Gapped between described flange and guide pillar.
Advantage of the present invention is: 1) adopt the guide frame of this Fine punching die frame, guide pillar can with bushing dismounting, the structure that lining and die shoe are detachable is conducive to the installation of mould and the reconditioning of die point, the prolongation mold use life-span; 2) adopt the guide frame of this Fine punching die frame, due to lining and die shoe employing interference fit, so the positioning accuracy of lining on die shoe is high, guarantee still accurately the leading of the BB1 of dismounting again, guide pin bushing at mould; 3) adopt the guide frame of this Fine punching die frame, because the profile of lining is little, so shared space is little on die shoe.4) adopt the guide frame of this Fine punching die frame, because lining and die shoe adopt bondingly, make the lining difficult drop-off, so the assurance mould bases is safe and reliable.5) adopt guide pin bushing in the guide frame of this Fine punching die frame to be pressed into end the same with guide end external cylindrical surface diameter, there is no step and escape on the surface, make handling ease, installation easily and more firm, and the guide pin bushing quality is good and can guarantee the good guidance precision.
Description of drawings
Fig. 1 is structural representation of the present invention.
In figure, 1 is upper bolster, the 2nd, and guide pin bushing, the 3rd, guide pillar, the 4th, lining, the 5th, die shoe, the 6th, flange, the 7th, screw.
The specific embodiment
A kind of guide frame of Fine punching die frame, comprise upper bolster 1, die shoe 5, guide pin bushing 2, lining 4, guide pillar 3, flange 6 and screw 7, be taper fit between the inner surface of described guide pillar 3 and lining 4, fix by screw 7 and flange 6 between guide pillar 3 and lining 4 lower surfaces, described lining 4 outer surfaces are cylindrically to match with the hole on die shoe 5, described lining 4 outer surfaces are coniform, described guide pin bushing 2 outer surfaces are cylindrical, match with the hole on upper bolster 1, gapped between described flange 6 and guide pillar 3.
Claims (5)
1. the guide frame of a Fine punching die frame, comprise upper bolster, die shoe, guide pin bushing, lining, guide pillar, flange and screw, it is characterized in that: for taper fit, fix by screw and flange between guide pillar and lining lower surface between the inner surface of described guide pillar and lining.
2. the guide frame of a kind of Fine punching die frame according to claim 1 is characterized in that: described sleeve outer surface is cylindrically to match with the hole on die shoe.
