Abstract
The utility model relates to a serial double-headed stud upsetting-extruding mold for a turnout of a special high-speed passenger transportation line, which comprises a common component and a replaceable special component. The common component comprises an upper mold jacket and an ejection rod, and the replaceable special component comprises an upper mold, a lower mold and an upper mold core; the upper mold jacket is sleeved on the upper part of the lower mold, the upper mold is sleeved in a cylindrical hole of the upper mold jacket, and the upper mold core is sleeved in the upper mold; and a cavity with the same shape as a double-headed stud is formed between the upper mold and the lower mold, and the ejection rod with the vertical position being adjustable is arranged in the cylindrical hole of the lower mold. The utility model has the beneficial effects: 1, the double-headed stud upsetting-extruding mold has a reasonable design structure and good machining process and is easy to operate; 2, the rate of utilization of raw materials can be increased by 30 percent, and the material cost can be saved; 3, the amount of metal cutting of the double-headed stud can be reduced, the machining time can be saved by 40-50 percent, and the machining cost can be decreased; 4, the production cycle can be shortened, the power consumption can be reduced, the cutter loss can be decreased; and 5, the product quality and production efficiency can be improved.
Description
Technical field
The utility model belongs to the technical field of fastening of railway switch.
Background technology
High speed passenger dedicated railway track switch is many with serial studs kind specification, and regular size has two kinds of M24 and M27, and its length series is maximum by 135～300mm consumption, and every increase 5mm increases a length specification.The former manufacture of studs is seen shown in Figure 1 for directly to form with the direct machined of the round bar of certain specification.This method has not only been wasted great deal of raw materials, and the machined cycle is long, and the cutter loss is too fast, and production efficiency is low.Thereby how to improve utilization rate of raw materials and just become an important topic in the mould design.
Summary of the invention
The utility model purpose is to use serial studs to high speed passenger dedicated railway track switch, uses upsetting squeeze art designs particular manufacturing craft, realizes the gathering stock of parts, to improve the steel stock utilization.
Specifically, high speed passenger dedicated railway track switch is with serial studs upsetting squeeze mould, and it is made up of general part and replaceable special purpose parts, and general part comprises patrix overcoat and push rod, and replaceable special purpose parts comprises upper die and lower die and patrix fuse; The patrix overcoat is enclosed within counterdie top, and is with patrix in the patrix overcoat cylindrical hole, is with the patrix fuse in the patrix; Between upper die and lower die, be shaped on the cavity identical, the adjustable push rod of upper-lower position is housed in the cylindrical hole in counterdie simultaneously with the studs outer shape.
The utility model beneficial effect: 1, stud upsetting squeeze mould project organization is reasonable, simple to operate, and the process for machining performance is good.2, utilization rate of raw materials has improved 30%, has practiced thrift fee of material.3, reduce the metal cutting amount of studs, saved for 40%～50% machined man-hour, practiced thrift the machined expense.4, shorten the production cycle, reduced power consumption, reduced cutter loss etc.5, improve product quality and production efficiency.

Fig. 3 is the utility model structural representation (cutaway view).
Fig. 4 is the utility model studs upsetting squeeze mould structure broken away view.
The specific embodiment
Provided the utility model specific embodiment like Fig. 2-4.High speed passenger dedicated railway track switch is with serial studs upsetting squeeze mould, and it is made up of general part and replaceable special purpose parts, and general part comprises patrix overcoat 1 and push rod 5, and replaceable special purpose parts comprises patrix 2, counterdie 4 and patrix fuse 3; Patrix overcoat 1 is enclosed within counterdie 4 tops, and is with patrix 2 in patrix overcoat 1 cylindrical hole, is with patrix fuse 3 in the patrix 2; Between patrix 2 and counterdie 4, be shaped on the cavity identical, the adjustable push rod 5 of upper-lower position is housed in the cylindrical hole in counterdie 4 simultaneously with the studs outer shape.Patrix overcoat 1 integral body is cylindrical, and the bottom is shaped on boss.Cylindrical hole port in the patrix 2 is for enlarging mouth, and patrix fuse 3 tops are shaped on the boss that cooperates with it simultaneously.Replaceable special purpose parts patrix 2, counterdie 4 and patrix fuse 3 all are furnished with a plurality of, and a plurality of replaceable special purpose parts shape is identical, size and studs specification coupling.
The utility model principle:
Shown in Figure 4 upper die and lower die and patrix fuse belong to special purpose parts in order to split mould structure, can match according to studs M24 and two kinds of specifications of M27, can produce the different size specification of the short end of studs length through changing the patrix fuse.Patrix overcoat and push rod belong to general part, and interchangeable use through regulating the push rod upper-lower position, can be produced the different size specification of the long end of studs length.The pressure required according to upsetting squeeze, the upsetting squeeze moulding process of stud realize that on JB23-80 tilting-type forcing press the stud of M24 specification selects for use the round bar of Φ 28mm, the stud of M27 specification to select for use the round bar of Φ 30mm hot-pressed.
