Problems solved by technology

[0003] The heat dissipation fins are processed by hobs, but most of the existing hobs are of one-piece structure, which wears out after a period of time and needs to be replaced as a whole, which increases the cost, and can only process one type of fin product, so the use is limited

Abstract

The invention discloses a wear-resistant assembled fin hob. The wear-resistant assembled fin hob comprises a hob mounting shaft, wherein rotating shafts connected with a driving device are arranged onthe two end surfaces of the hob mounting shaft; multiple sets of wear-resistant hobs are mounted on the hob mounting shaft; a distance adjusting baffle ring is arranged between two adjacent wear-resistant hobs; each set of wear-resistant hob comprises two parallel circular table-shaped clamping pieces with narrow externals and wide internals; multiple mounting holes are uniformly distributed in the peripheries of the two opposite side surfaces of the two clamping pieces; rotating rods are rotationally mounted between the corresponding mounting holes through center shafts, and are projected out of the clamping pieces; and sealing baffle plates are arranged on the two end surfaces of the hob mounting shaft. Once the wear-resistant assembled fin hob is damaged, only the damaged parts need tobe replaced; in the process of pressing fin tooth shapes by the wear-resistant hobs, the rotating rods are rotationally rubbed to improve the wear resistance; and the distance between the wear-resistant hobs can be adjusted as needed, and only the distance adjusting baffle rings with proper thicknesses need to be adopted, so that the machining performance of the device is improved, and the rangeof the device is widened.

Description

technical field [0001] The invention relates to the technical field of fin processing hobs, in particular to a wear-resistant assembled fin hob. Background technique [0002] Finned radiators are often used in the field of radiators, and finned radiators are the most widely used heat exchange equipment in gas and liquid heat exchangers. Fins are generally used to increase the heat exchange surface area of ​​the heat exchange device by adding metal sheets with strong thermal conductivity on the surface of the heat exchange device that requires heat transfer. [0003] The heat dissipation fins are processed by hobs, but most of the existing hobs are of one-piece structure, which wears out after a period of time and needs to be replaced as a whole, which increases the cost, and can only process one type of fin product, so the use is limited . Contents of the invention [0004] The invention aims to solve the deficiencies of the prior art, and provides a wear-resistant assem...
