Description

Punching die structure for track traffic hoop bolt, longitudinal bolt
Technical field
The present invention relates to the technical field of plant equipment, particularly relate to railway hoop bolt, vertical from the compression mold device to bolt, specifically for the punching die structure of track traffic hoop bolt, longitudinal bolt.
Background technology
Hoop bolt and longitudinal bolt are a kind of standard components that uses in track traffic, and along with construction and the popularization of each large and medium-sized urban mass transit network of the whole nation, the usage quantity of hoop bolt or longitudinal bolt also sharply increases.But therefore because there is an arc-shaped bend in the bar section of this kind bolt on spatial shape, to guarantee that the quality of product also is not easy very much, its Major Difficulties be curved rushing of product or this procedure that bends on.Hoop bolt and longitudinal bolt are all that to adopt metal steel be raw material; because the metal steel have rebound coefficient; therefore common diel is rushed the curved or rear designing requirement that does not usually all reach drawing of bending for the first time at bolt, often also need to again supplement punching press by little punch press.The method of punch process has caused the workload increase so repeatedly, and production efficiency is very low, thereby production cost is relatively high.The one time punching molded equipment that adopts is also arranged in prior art; but the punching press bed die all adopts the roller type design; due to the product contact-making surface of roller and punching press very little; and the ram ratio of the hoop bolt of punching press and longitudinal bolt is larger; so the product surface after punching press often has obvious concavo-convex defect; therefore the fineness of product is poor, causes outward appearance more ugly.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned prior art present situation, and production efficiency is high, fineness good, simple to operation, the reliable and disposable stamping forming a kind of punching die structure for track traffic hoop bolt, longitudinal bolt of product that completes of energy and provide.
the present invention solves the problems of the technologies described above the technical scheme that adopts: for the punching die structure of track traffic hoop bolt, longitudinal bolt, comprise upper stamping die setting up and down and lower stamping die, the punching press contact-making surface of upper stamping die is the arcwall face with R radius, and along whole arc length, is shaped with together the punching press upper groove arc suitable with stamping products side face arc on this punching press contact-making surface, lower stamping die comprise the stamping die base plate and spacing adjustable be symmetrical set two punching press movable block supports on this stamping die base plate, on each punching press movable block support, equal hole axle coordinates rotation to be articulated with the punching press movable block, on the punching press supporting surface of this punching press movable block, be shaped with the punching press low groove arc with punching press upper groove arc corresponding matching, set up respectively in the punching press low groove arc that is supported on two punching press movable blocks at the two ends of stamping products, upper stamping die and lower stamping die move up and down and coordinate the extruding stamping products, force the bar section of this stamping products to produce the arc deforming bending with R radius.
For optimizing technique scheme, the concrete measure of taking also comprises:
Above-mentioned upper stamping die comprises upper punch coping and upper punching template, the punching press contact-making surface is formed on the lower end of punching template, above the upper end of punching template is through the dismountable lower surface that is fixedly mounted on the upper punch coping of patrix hold-down screw, and upper punch coping and upper punching template are T-shaped structure on side view.
Above-mentioned punching press movable block support is shaped with two support ledge, and support ledge fixedly is equipped with rack pin shaft, and the punching press movable block rotates and wears and join mutually between two support ledge and with bracket pins axis hole axle.
The bottom surface of above-mentioned punching press movable block support horizontally slips and matches with the end face of stamping die base plate, the penetrating strip slide opening that is shaped with counter sink on the stamping die base plate, punching press movable block support is shaped with circular locating hole, in strip slide opening and locating hole, is equipped with successively the bracket fixing bolt of the punching press movable block support that is locked.
On the end face of above-mentioned stamping die base plate, be shaped with recessed guide-localization groove, in the guide-localization groove, fixedly be embedded with the support positioning key, on the bottom surface of punching press movable block support, be shaped with accordingly the guide chute that slides along this support positioning key positioning and guiding.
The outer end that is positioned at each punching press movable block support on the end face of above-mentioned stamping die base plate is provided with backer's adjustable plate, backer's adjustable plate vertically is fixedly mounted on the stamping die base plate through backer's set bolt, on backer's adjustable plate, be shaped with the bracket adjustment screwed hole, in this bracket adjustment screwed hole, spiral is fitted with the bracket adjustment bolt that coordinates with punching press movable block support (22) apical grafting.
The top screw thread of above-mentioned backer's adjustable plate is equipped with the adjusted bolt that coordinates with the stamping products apical grafting.
The lower end root of above-mentioned backer's adjustable plate is put and is positioned in backer's locating slot that the stamping die base plate is shaped with.
In above-mentioned punching press movable block punching press low groove arc, near outer end, be shaped with the screw thread suitable with the stamping products thread segment.
Compared with prior art, the punching press contact-making surface of upper stamping die of the present invention is the arcwall face with R radius, on the punching press contact-making surface, along whole arc length, is shaped with together the punching press upper groove arc suitable with stamping products side face arc; The adjustable two punching press movable block supports that are symmetrically arranged with of spacing on the stamping die base plate of lower stamping die, rotate on punching press movable block support to be articulated with stamping products and support the punching press movable block that coordinates, and in the punching press movable block, is shaped with punching press low groove arc.Punching press low groove arc has increased the contact area with stamping products, has guaranteed the surface smoothness of product, and stamping products stamps out the bolt that bar section has the R radius under the acting in conjunction of upper stamping die and lower stamping die.Advantage of the present invention is: can disposablely complete the bolt punch forming, improve product quality and production efficiency, reduce production costs and personnel labor intensity, and have the characteristics of simple to operate, reliable and long service life.
