Abstract
A cold extrusion workpiece of a motor hub comprises a workpiece body, and is characterized in that a plurality of grooves are circumferentially formed on the inner ring of the workpiece body; and protruding ribs are circumferentially distributed between the adjacent grooves. Compared with the prior art, the cold extrusion workpiece of the motor hub has the advantages that the structure is improved; the grooves are formed on the inner ring of the cold extrusion workpiece in advance and the protruding ribs are arranged between the adjacent grooves, so that during cold extrusion of the workpiece, the integral cutting of the inner ring is not required, and only part of the protruding ribs are cut for forming a product, so that the machining allowance is reduced, the machining efficiency is improved, and the inner surface of the machined workpiece can be protected from damage.
Description
Technical field
The utility model relates to a kind of cold extrusion workpiece of motor wheel hub.
Background technology
At present, cold-extrusion technology has been widely used in all trades and professions, still, cold-extrusion technology of the prior art exists also that effect is low, die life short problems such as (mainly being tool wear).
In the bigger course of processing of workpiece chips surplus, in the cold pressurization machine-shaping process like motor wheel hub, common wheel hub cold extrusion workpiece all is to reserve certain thickness inner ring allowance; Then through the cold extrusion mode in the required structure of wheel hub inner ring machine-shaping, this mode is on the one hand because the inner ring surplus is big, waste material is difficult for discharging in the working angles; Long processing time on the other hand; Add the influence that receives the material of workpiece own, causing working (machining) efficiency low, up to the present; Traditional wheel hub cold extrusion workpiece can only be fit to medium quantity batch processing, also has certain distance from producing in enormous quantities.
The utility model content
The utility model technical problem to be solved is that a kind of cold extrusion workpiece that cold extrusion improves working (machining) efficiency and the better motor wheel hub of squeezing effect that helps is provided to above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of cold extrusion workpiece of motor wheel hub; Include workpiece body; It is characterized in that: the inner ring of described workpiece body has along a plurality of grooves of circumferentially offering, forms the convex tendon along circumferential arrangement between the adjacent said groove.
As preferably, described workpiece body outer ring is along circumferentially offering the installation draw-in groove.
Preferred as further, the end face of described workpiece body also offers the aperture that can connect end cap.
Compared with prior art, the advantage of the utility model is: improved the structure of wheel hub cold extrusion workpiece, processed groove in advance at the inner ring of cold extrusion workpiece; Make to form convex tendon between the adjacent grooves that workpiece adds man-hour carrying out cold extrusion, need not to carry out the cutting of whole inner ring; Only need cut the part convex tendon just can shaped article; Reduce allowance, improved working (machining) efficiency, and avoided damaging the work piece inner surface of having accomplished machining.
Description of drawings
Fig. 1 is the structural representation of the wheel hub cold extrusion workpiece of the utility model embodiment.
Fig. 2 is the three-dimensional cutaway view of the wheel hub cold extrusion workpiece of the utility model embodiment.
Fig. 3 is the structural scheme of mechanism after the wheel hub cold extrusion workpiece machine-shaping of the utility model embodiment.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Like Fig. 1, shown in Figure 2; Present embodiment is a kind of cold extrusion workpiece of motor wheel hub, and this workpiece includes workpiece body 1, in order to reduce allowance; Increase work efficiency; Before carrying out cold extrusion, at first the inner ring in workpiece body 1 has along a plurality of grooves 11 of circumferentially offering through the machining moulding, promptly forms the convex tendon 12 along circumferential arrangement between the adjacent groove 11; Draw-in groove 13 is installed along circumferentially also offering in workpiece body 1 outer ring, and the end face of workpiece body 1 also offers the aperture 14 that can connect end cap.
After adopting the Workpiece structure of present embodiment, in the cold extrusion course of processing, only needing to cut the part convex tendon with broaching tool just can be with formed product; Reduced chipping allowance; The life-span of cutter is improved greatly, also shorten the man-hour of processing simultaneously thereupon, help realizing producing in enormous quantities.
As shown in Figure 3; The workpiece that is embodiment carries out the shaped article 2 after cold extrusion is processed; The convex tendon that the convexity 21 that can see the workpiece inner ring is the cold extrusion workpiece cuts and forms after the part surplus; The destruction that the groove surfaces that forms between protruding 21 does not receive the cold extrusion cutter has guaranteed workpiece surface quality.
