Heavy rim rounder

Abstract

The invention relates to a heavy rim rounder comprising a center shaft mounted on a fixed base and a crush-resistance ring capable of rotating around the center shaft. Cams are distributed on the outer circumference of the crush-resistance ring. A carrier-rod disc is arranged on the periphery of the crush-resistance ring, guide holes which run through radially and are opposite to the corresponding cams are uniformly distributed along the circumference of the carrier-rod disc, and carrier rods capable of telescoping radially along the guide holes are arranged in the guide holes. The outer sides of the carrier rods can extend out of the guide holes while the inner sides of the carrier rods are abutted against outer cam surfaces; during rotation of the crush-resistance ring, the cam surfaces move so as to push the carrier rods outwards. A plurality of synchronous cylinders capable of driving the crush-resistance ring to rotate are mounted on the fixed base. As the cams output radial stretching force directly, the heavy rim rounder simple in structure and convenient to operate has the advantages of short range of motion, compact structure, high reliability and high output pressure and can meet processing requirements of heavy rims.

Description

technical field [0001] The invention relates to a processing equipment for heavy-duty vehicle rims, in particular to a heavy-duty rim rounding machine. Background technique [0002] The main body of the rim used by some large-scale vehicles and construction machinery is usually made of steel plate coiled into a tube shape and processed after welding. Since the roundness accuracy of the tube body formed by the coiled plate is difficult to meet the welding requirements of the circular parts at both ends, it is necessary to The roundness of its shape is corrected by the round support mechanism. Traditionally, the round support mechanism usually adopts the expansion mechanism with taper fit, which not only has a large axial dimension and complicated equipment, but also has limited expansion force, which cannot meet the processing requirements of heavy-duty rims. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heav...
