Buckling support roll and buckling support roll assembly machine

Abstract

The invention discloses a buckling support roll and a buckling support roll assembly machine. An assembly stander is provided with a pressure machine; a pressure head and a base are provided with a buckling die respectively; a circular insertion hole of which axis is vertical to a buckling surface is formed in the buckling die; a flat-bottom circular groove of which axis is on the same straight line as the axis of the circular insertion hole is formed on the buckling surface; a stepped columnar bearing director of which the outer section is inserted in the circular insertion hole and which has a small outer section diameter and a large inner section diameter is arranged in the flat-bottom circular groove; and the bearing director is provided with a through hole of which axis is on the same straight line as the axis of a column of the bearing director. The manufacturing charge is low, the process for manufacturing the support roll is simple, particularly buckling bearing cups at two ends of a steel tube and bearings pushed to the bottoms of the bearing cups and a support roll shaft are combined by a buckling die, and the shape and position of the support roll are ensured after the combination; and the manufactured support roll has the advantages of higher coaxial degree, smooth two ends and lower processing cost. The buckling support roll assembly machine is a better device special for manufacturing a belt conveyor support roll.

Description

technical field [0001] The invention relates to an idler roller for a belt conveyor and manufacturing equipment for the idler roller, in particular to a crimping idler roller for a belt conveyor and an assembly machine for the crimping idler roller. Background technique [0002] The idler roller is an important part of the belt conveyor. There are many idler rollers on the belt conveyor. The idler rollers are neatly arranged on the frame to support the conveyor belt and the weight of the material. The idler roller is the A small part, the structure is not complicated, its technical content is low, far lower than the design of the whole machine, but from the perspective of use, it is a very important part of the belt conveyor, the quality of the roller is good or bad It directly affects the performance of the belt conveyor, and there are many belt conveyor accidents caused by the poor quality of the idlers. The most common ones are inflexible rotation, tearing of the belt, de...

AI Technical Summary

Problems solved by technology

When making idlers, the two steps of welding the bearing cups at both ends of the steel pipe and pushing the bearings to the bottom of the bearing cups are the most important steps in making idlers. Using the above method to manufacture idlers requires electric welding machines and bearing assembly machines. And other equipment, the investment of the equipment is large, and the production process is more complicated, especially the bearing cup is welded to both ends of the steel pipe by welding, not only the processing cost is large, but the shape and posit
