Abstract
The utility model relates to an internal gear extruding roller for processing cylindrical components such as an auto upper armrest pipe, pertaining to the technical field of special device for mechanical processing. The main technical proposal is that the extruding roller is internally and evenly provided with convex teeth. The utility model has reasonable structure and convenient processing; when the convex teeth on the roller press into the outer diameter of workpiece, the passive device is prevented from sliding and the concave rolled is accurate and even in distance. Meanwhile, since that the internal extruding convex teeth rotate in the same direction as the concaves on the workpiece, the interference of the convex teeth and the concaves rarely comes up and the rolled concaves are clearer and more beautiful.
Description
Technical field:
The utility model relates to a kind of internal tooth squeezing roller, is used for cylindrical parts such as handrail tube on the processing automobile, belongs to machining isolated plant technical field.
Technical background:
Before the utility model is made, in prior art, adopt the roll extrusion mode to go out even pit, normally adopt and on the roller external diameter, make the convex tooth at cylindrical work surface edging.After roller external diameter convex-shaped tooth pressure was gone into the workpiece outer surface, roller and workpiece were done rightabout rotation (workpiece or roller, wherein is active rotation, another part is passive rotation).The roller of this kind structure when the required concave pit in cylindrical work surface more shallow, and when upward distribution is rarer around, outer squeezing roller convex tooth can not guarantee that abundant convex tooth is pressed into the workpiece outer surface simultaneously, in the edging process, easily produce and skid, make pit fall into disarray on the workpiece, overlapping, roll extrusion work can't normally be carried out.
Technology contents:
The purpose of this utility model is to overcome above-mentioned weak point, thereby when providing a kind of roller upper raised teeth to be pressed into the workpiece external diameter, can guarantee to have and more multiple toothly be pressed into simultaneously, when workpiece and roller rotate in the same way, difficult generation is skidded, roll out the pit distance accurately, and pit is clear, internal tooth squeezing roller attractive in appearance.
Main solution of the present utility model is achieved in that
It mainly adopts and evenly be shaped on double wedge 4 in squeezing roller 2.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structure working principle figure;
Fig. 3 is the utility model working state figure;
The specific embodiment:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly adopts and evenly be shaped on double wedge 4 in squeezing roller 2, and double wedge 4 can fuse with squeezing roller 2, also can be used as inset type.In workpiece 1 was installed in squeezing roller 2, squeezing roller 2 outer being equipped with were decided longitude circle 3, and adopt bearing 5 fixing.When the double wedge on the squeezing roller 2 is pressed into the workpiece external diameter, can guarantee more multiple toothly to be pressed into simultaneously.When workpiece and roller rotate in the same way (wherein one is active rotation, and another part is passive rotation, and passive rotation is difficult for producing skids).
Compared with the prior art the utility model has the following advantages:
The utility model is rational in infrastructure, and is easy to process; When the roller upper raised teeth is pressed into the workpiece external diameter, passive Part is difficult for generation and skids; Roll out the pit distance accurately, evenly, simultaneously because on interior extruding double wedge and the workpiece The pit direction of rotation is identical, so little at rolling process barrel shaped tooth and pit interference, the pit of extrusion is more clear Clear, attractive in appearance.
