Abstract
The utility model relates to a guide-plate punching blanking continuous mould distanced by a guide pin. The guide-plate punching blanking continuous mould distanced by the guide pin is composed of a mould handle, a bolt, a punching convex mould, a blanking convex mould, the guide pin, a fixed baffle pin and a finger stop pin, wherein the mould handle (1) is in fastened connection with an upper mould base through the bolt (2) and the guide pin (5) and the blanking convex mould (4) are in slide clearance fit with each other. The mould has the advantages of firm and reliable action, excellent pressure transferring, precise product size and suitability for the punching forming of various thick or thin materials.
Description
Technical field
The present invention relates to metal cool-press and be shaped, is the guide plate punching and blanking continuous mould of pilot pin spacing.
Background technology
Blanking die stamping-out to as if billot or coiled strip, and perforating die processing to as if blanking or passed through the semi-finished product of other punch process.At mould, manufacture boundary at present and there is (1) without guiding blanking die for piercing and blanking die, itself is without guider, to rely on the guide rail of forcing press to lead to slide block, it is simple in structure, and the manufacturing cycle is short, and cost is low, but mould is installed and is adjusted blade clearance difficulty and be difficult for adjusting evenly, blanking part is of poor quality, and die life is short, operates dangerous.(2) guide-plate type blanking die, it is relatively simple for structure, and the guiding of upper die and lower die is to rely on the matched in clearance of guide plate and punch to carry out.Though its mould structure is simple, but the fit clearance of guide plate and punch must be less than clearance between punch and die, and guide plate must have adequate thickness, and punch is enclosed within all the time in guide plate hole and slides up and down, and therefore this mould is suitable for the shorter forcing press of stroke.In order to address the above problem, I am according to mould manufacturing experience for many years, and spy provides following a kind of mold mechanism to solve an above-mentioned difficult problem.
Summary of the invention
The present invention is to provide the guide plate punching and blanking continuous mould of pilot pin spacing, and it is that the guiding of upper mould and counterdie is all to adopt guide plate guiding.Die shank adopts screw-in, with screw thread, is connected with upper bolster, and the distance between piercing punch and blanking punch is exactly just step pitch.During feeding, first by fixing pin stop, carry out coarse positioning, then carry out fine positioning by the pilot pin being contained on blanking punch.This mold mechanism action is solid and reliable, and pressure transmission is good, and pilot pin spacing structure is simple, positioning accurate Huaihe River, and during punching, pilot pin is difficult for splitting off.The guide plate punching and blanking continuous mould of pilot pin spacing, has solved while installing without guiding blanking die, mould, adjusts blade clearance difficulty, and inhomogeneous, and stamping-out is of poor quality, and die life is short, operates unsafe problem.Solved guide-plate type blanking die, the fit clearance of guide plate and punch must be less than punch, and guide plate must have enough thickness, and punch slides on leading all the time and descending in guide plate, is only suitable for the problem of the short forcing press of stroke.The guide plate punching and blanking continuous mould of pilot pin spacing, it is characterized in that: die shank (1) is fastened on upper baffle plate with screw (2), piercing punch (3) is arranged in the stepped hole of punch retainer, then use screw fastening, blanking punch (4) coordinates with pilot pin (5) glade plane space, fixedly pin stop (6) is fastened on lower bolster, and trigger stop (7) is fastened on lower mould one side's lateral surface.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated
Shown in figure
Sectional side elevation when Fig. 1 is the punching press of mould matched moulds
Fig. 2 is the top view of mould
In figure, numeral number represents respectively:
1---die shank 2---screw 3---piercing punch
4---blanking punch 5---pilot pin 6---is pin stop fixedly
7---trigger stop
The specific embodiment:
As shown in the figure: the guide plate punching and blanking continuous mould of pilot pin spacing.These mould upper die and lower die adopt guide plate guiding.Die shank (1) adopts screw-in, with screw thread, is connected with upper bolster.Thread looseness when preventing punching press.Adopted the holding screw (2) of the junction of the edges of two sheets of paper to connect.Distance between piercing punch (3) and blanking punch (4) is exactly feeding step pitch.During feeding, first by fixing pin stop (6), carry out coarse positioning, then carry out fine positioning by 2 pilot pins (5) that are contained on blanking punch.Pilot pin is H7/r6 with coordinating of blanking punch, and the structure of its link should guarantee that mounting or dismounting are convenient when reconditioning punch, and therefore, the hole that blanking punch is installed pilot pin is a through hole.The shape of pilot pin head should be conducive to when correcting to insert the cooperation in the ，Ta Yu hole, hole having rushed should be gapped.In order to guarantee the correct spacing of initial workpiece, therefore be provided with beginning stop gauge, when initial workpiece punching, with hand push trigger stop (7), make it from stock guide, stretch the front end that blocks billot, can rush 2 holes of the 1st, just all by fixing pin stop (6) control feeding step pitch, make coarse positioning during each stamping-out later.
Claims (1)
1. the guide plate punching and blanking continuous mould of pilot pin spacing, it is characterized in that: die shank (1) is fastened on upper baffle plate with screw (2), piercing punch (3) is arranged in the stepped hole of punch retainer and then uses screw fastening, blanking punch (4) coordinates with pilot pin (5) glade plane space, fixedly pin stop (6) is fastened on lower bolster, and trigger stop (7) is fastened on lower mould one side's lateral surface.
