Abstract
The utility model relates to the technical field of processing equipment of auto parts, in particular to a cold extrusion processing device for a worm shaft. The cold extrusion processing device comprises a positioning seat, wherein a positioning hole is formed in the positioning seat; a rolling device is arranged on one side of the positioning seat and comprises two rolling wheels which are arranged symmetrically; and the gap between the two rolling wheels and the positioning hole are linearly arranged. The cold extrusion processing device for the worm shaft is simple in structure, reasonable in arrangement and convenient to operate.
Description
Technical field
The utility model relates to the auto parts and components technical field of processing equipment, especially relates to a kind of worm shaft cold extrusion making device.
Background technology
Worm shaft is rain shaving electrical machine and to shake the window motor be kernel component before and after the automobile.The quality of worm shaft quality and its processing method and process equipment have much relations, at present, mainly adopt the whirling mill machining to form for pressure angle less than the worm shaft of partially thin profiles of tooth of 20 degree, this processing method has not only been cut off the metal fibrous tissue of material internal, rigidity and the intensity of part have been weakened, reduced service life, and the tooth-face roughness numerical value of processing is high, function is used in impact.Improve so be necessary to carry out process equipment, to overcome the deficiency of existing process equipment.
The utility model content
For the deficiency that above-mentioned prior art exists, the characteristics such as the purpose of this utility model provides a kind of worm shaft cold extrusion making device, and it is simple in structure, and is easy to operate.
To achieve these goals, the technical scheme that adopts of the utility model is:
A kind of worm shaft cold extrusion making device described in the utility model, comprise positioning seat, be provided with locating hole in the described positioning seat, described positioning seat one side is provided with rolling device, described rolling device comprises symmetrically arranged two rollers, the setting that is in line of the gap of described two rollers and locating hole.
Further, described roller one side is provided with straightening-wheel A, and the roller opposite side is provided with straightening-wheel B.
After adopting said structure, the beneficial effects of the utility model are: the utility model adopts rolling device that the worm shaft workpiece is carried out roll extrusion, like this, not only can not cut off the metal fibrous tissue of workpiece material inside, to keep rigidity and the intensity of part, prolonged service life, and the tooth-face roughness numerical value of processing is low, greatly improves product quality.The utility model is simple in structure, arranges rationally, and is easy to operate.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure:
1, straightening-wheel A; 2, roller; 3, straightening-wheel B; 4, workpiece;
5, positioning seat; 6, locating hole.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, a kind of worm shaft cold extrusion making device described in the utility model comprises positioning seat 5 and rolling device, and these two parts consist of the utility model agent structure.
Be provided with locating hole 6 in the described positioning seat 5, when processing work 4, workpiece 4 one ends insert in the locating hole 6, are fixed the location by workpiece 4.
Described positioning seat 5 one sides are provided with rolling device, and described rolling device comprises symmetrically arranged two rollers 2, the setting that is in line of the gap of described two rollers 2 and locating hole 6.Described workpiece 4 other ends stretch between two rollers 2, and roller 2 can carry out effective roll extrusion to workpiece 4.
Described roller 2 one sides are provided with straightening-wheel A1, and roller 2 opposite sides are provided with straightening-wheel B3, arrange like this, can be effectively gear and the groove of roll extrusion be carried out alignment.
Gear of the present utility model and groove all are to form by roll extrusion, not only can not cut off the metal fibrous tissue of workpiece material inside, to keep rigidity and the intensity of part, prolong service life, and the tooth-face roughness numerical value of processing is low, greatly improves product quality.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
