Embodiment Construction

[0014] The following specific implementation methods are only for better illustration of this patent, and do not limit the rights of the patent application.

[0015] A cold extrusion forming method for blowing and combing roller teeth. The roller blank is clamped on the cold extrusion equipment, the equipment is started, and the power traction roller parts rotate and move axially at the same time; the left and right sides of the roller blank The cold head is continuously extruding the roller blank under the guidance of the tool holder. The roller with different tooth shape adopts different cold head. The groove shape of the roller can be saw tooth, arc tooth or trapezoidal tooth. The groove shape of the roller is extruded on the periphery of the workpiece at the same time.

[0016] First, clamp the roller blank on the cold extrusion equipment, rotate under the traction of the power, and also move axially at the same time, the cold heads on the left and right sides of the rolle...

Abstract

The invention relates to the technical field of processing of blowing-carding rollers and particularly relates to a tooth form cold extrusion forming method for a blowing-carding roller. The method comprises the steps as follows: a roller blank is clamped on cold extrusion equipment, the equipment is started, and the roller blank is rotated and is axially moved under the traction of a power force at the same time; cold heads on the left and the right sides of the roller blank extrude the roller blank continuously under the guide of a knife rest; different cold heads are adopted for different tooth forms of rollers, and roller grooves can be saw-shaped teeth, circular arc-shaped teeth or trapezoidal teeth and are formed by exchanging the cold heads to perform extrusion to the periphery of the roller blank simultaneously. The method provided by the invention has the advantages of saving material, improving the production efficiency, obtaining a roller with ideal precision and roughness, and improving the mechanical property of the surface of the roller; and the method is suitable for a blowing-carding solid roller as well as for a hollow roller like a spinning machine.

Description

technical field [0001] The invention relates to the technical field of blowing-carding roller processing, in particular to a method for cold-extruding the teeth of the blowing-carding roller. Background technique [0002] For a long time, the traditional blowing-carding roller tooth profile processing is cut by planer or milling machine. The groove shape must be corrected and polished to meet the accuracy and roughness requirements, and the strength after forming is the same as that of the green body. Performance is not improved. The cold extrusion forming technology of blowing and carding roller teeth is to use the plastic deformation of metal materials to extrude the surface of the roller body through the formed cold head to make the groove shape of the roller. By adjusting the extrusion depth of the cold head, a blowing-carding roller that meets the requirements for the accuracy and roughness of the notch of the roller is manufactured. Contents of the invention [000...
