A device for segmented knurling of shaft products

Abstract

The invention relates to a device for performing segmented knurling on a shaft product. The device comprises a supporting frame shaped like the Chinese character 'ao'. A first knurl wheel and a second knurl wheel are horizontally arranged in the supporting frame and are in parallel. The shaft product is horizontally arranged, between the first knurl wheel and the second knurl wheel, on the supporting frame. The two ends of the shaft product are connected to the two side walls of the supporting frame in a rotating mode respectively. The first knurl wheel and the second knurl wheel respectively comprises a rotary shaft and at least three knurl rollers which are sequentially arranged on the corresponding rotary shaft at intervals in the axial direction. According to the device for performing segmented knurling on the shaft product, through the segmented first knurl wheel and the second knurl wheel, extrusion is performed from the two sides of the shaft product at the same time, so that segmented knurls are machined on the shaft product in a one-off mode, and knurling efficiency is greatly improved; meanwhile, the shaft product is prevented from being stressed in the single direction, deforming and bending, and the machining quality of the shaft product is greatly improved.

Description

Technical field [0001] The invention relates to a mechanical processing device, in particular to a device for processing segmented knurling on a long axis product at one time. Background technique [0002] Knurling is a mechanical process of rolling patterns on the knobs of metal products or other work surfaces, mainly for anti-skid. At present, the knurling of shaft products is squeezed on the outer surface of the shaft product through a knurling wheel and then rotated to form a circle of knurling. If it is necessary to form multiple circles of knurling on the same shaft product, It is necessary to squeeze the shaft product many times, and the position of the knurling wheel needs to be adjusted many times to press the knurling on the corresponding position of the shaft product. This is time-consuming and laborious, and the work efficiency is low; When knurling shaft products, only a knurling wheel is installed on one side of the outer diameter of the shaft product. The knurling...

Problems solved by technology

At present, the knurling of the shaft product is squeezed on the outer surface of the shaft product by the knurling wheel, and then rotated to form a circle of knurling. If multiple circles of knurling are to be formed on the same shaft product, Then the shaft product needs to be squeezed many times, and the position of the knurling wheel needs to be adjusted many times to press out the knurling on the corresponding position of the shaft product. In this way, it is time-consuming and laborious, and the work efficiency is low; When knurling the shaft products, the knurling wheel is only installed on one side of the outer diameter of the shaft product, and the knurling wheel strongly squeezes the shaft product in one direction. Because the shaft product is pressed in one direction, it is easy to Cause shaft products to be bent and scrapped, reducing the pass rate of processing
