Abstract

The utility model relates to a spline shaft cold forming processing apparatus, which is composed of a concave mould, a concave mould fixing body, a bottom base, a finial, a convex mould, a convex mould fixing body, an upper fixing plate, etc. A spline shaft under processing can be once formed by the arrangement of the concave mould and the convex mould. Moreover, the utility model has the advantages of high speed, high precision, etc. Therefore, the production cost is reduced and the work efficiency is raised.

Description

A kind of novel spline forming processing unit (plant)
Technical field: the utility model relates to a kind of processing unit (plant) of cold forming, particularly relates to a kind of novel spline forming processing unit (plant).
Background technology: at present, the processing method of splined shaft is general divides two kinds, metal cutting (bits are arranged) processing and ELEMENTARY INTRODUCTION TO NON.For bits processing is arranged is a kind of very common method at home, and process velocity is slow, efficient is low, precision also is difficult to reach requirement, especially for cooperating demanding spline, also need increase the processing of grinding tooth, and efficient is just lower like this.ELEMENTARY INTRODUCTION TO NON is a kind of novel spline processing method at home, and it is divided into methods such as rolling (cold beating), cold rolling and cold extrusion.Wherein cold printing method is subjected to device-restrictive, mainly is external employing, and the domestic essential import equipment of buying costs an arm and a leg, and only is fit to very large batch of production.Cold rolling processing employing roller or filament plate more generally use, but are subjected to the restriction of diameter of work size, modulus size.The purpose of this utility model just provides a kind of novel spline forming processing unit (plant), advantages such as speed is fast, efficient is high, once-forming that it has.
Summary of the invention: the purpose of this utility model is to realize like this, a kind of novel spline forming processing unit (plant) is made up of two parts mould up and down, it is characterized in that: described patrix is to be formed by connecting with bolt by upper mounted plate, punch retainer, centre at punch retainer and upper mounted plate has through hole, be provided with punch in the through hole, be equipped with top in the punch and spring; Described counterdie is to have base, die retainer plate, pressing plate to be formed by connecting with bolt, has through hole in the centre of base, die retainer plate, pressing plate, is provided with die in through hole, and the outside of die is provided with the die overcoat, and the bottom of die is provided with the die cushion block.The utility model is simple in structure, characteristics such as have that process velocity is fast, precision is high, raise the efficiency obviously.
Description of drawings: Fig. 1 is a structural representation of the present utility model
1, upper mounted plate 2, punch retainer 3, punch 4, top 5, die overcoat 6, die 7, die cushion block 8, pressing plate 9, die retainer plate 10, base
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing, in Fig. 1, a kind of novel spline forming processing unit (plant) of the utility model is made up of two parts mould up and down, it is characterized in that: described patrix is to be formed by connecting by upper mounted plate 1, punch retainer 2 usefulness bolts, centre at punch retainer 2 and upper mounted plate 1 has through hole, be provided with punch 3 in the through hole, be equipped with top 4 and spring in the punch 3; Described counterdie is to have base 10, die retainer plate 9, pressing plate 8 usefulness bolts to be formed by connecting, centre at base 10, die retainer plate 9, pressing plate 8 has through hole, is provided with die 6 in through hole, the outside of die 6 is provided with die overcoat 5, and the bottom of die 6 is provided with die cushion block 7.Workpiece need be treated during concrete enforcement, and workpiece one end is placed the die porch, ajusts workpiece, start press, make top downslide, guarantee to withstand the workpiece centre hole, continue to move down, at this moment, in the top retraction punch, punch end face workpiece pressing is along with moving down of punch, workpiece is pushed into die, becomes spline through after several crimp.For nonpenerative workpiece, then eject workpiece by following ejecting mechanism.The concavo-convex mould of design is a sub-assembly, and inner chamber studs with hard alloy, is processed into spline teeth after the mark section is pressed into, and there is the guiding awl every section porch, and first section have drop gradually to last one section tooth proportions, and the assurance workpiece progressively is out of shape.This die is fixed in the die overcoat, and the die overcoat fixes by pressing plate, die retainer plate and base, and the final and press table top of base is fixed.For running through extruding, then can be without pressing plate, to non-extruding, the increase liftout attachment of running through.The part of the upper die has top, and is top to the workpiece pre-determined bit, and top and punch is very little being slidingly matched, and punch is connected and fixed by punch retainer, upper mounted plate and press upper table face.
