Supporting structure for rolling round pipe of after-treatment exhaust system

Abstract

The invention provides a supporting structure for rolling a round pipe of an after-treatment exhaust system. The supporting structure comprises a limiting and fixing base. An adjustment limiting rod in the front-back direction is fixedly mounted at the bottom of the left end face of the limiting and fixing base through two bolts, and an adjustment fixing block in the front-back direction is mounted on the front portion of the left end face of the adjustment fixing rod through two bolts. A lifting adjustment rod in the vertical direction is locked and fixedly mounted on the front portion of theinterior of the adjustment fixing block through front bolts, and a left-right adjustment block is arranged at the bottom of the lifting adjustment rod in a sleeving manner and is fixedly mounted through rear bolts. A cylindrical supporting rod in the left-right direction is mounted on the front portion of the interior of the left-right adjustment block through a bearing and is locked through bolts. Through the arrangement of the adjustment limiting rod, the adjustment fixing block fixed through the bolts can be moved forwards and backwards to be adjusted, the lifting adjustment rod can be inserted into the adjustment fixing block conveniently to rise or fall to be adjusted and can be locked and fixed through the bolts, and thus, multiple adjustment is realized to meet the requirements fordifferent diameters and different lengths.

Description

technical field [0001] The invention belongs to the technical field of support structures, and in particular relates to a round pipe roll support structure of an aftertreatment exhaust system. Background technique [0002] Put the workpiece between the upper and lower rollers, and strictly control the parallel or perpendicularity between the center line of the workpiece and the axis of the rollers, so as to avoid distortion and misalignment after being rolled out. During the rolling process, the curvature should not change too much at one time, and it should be rolled gradually and checked with a sample at any time. When the diameter of the rolled piece is equal to or slightly smaller than the size of the pattern, stop the operation, weld the two ends firmly, and take the workpiece out of the roll. [0003] Based on the above, the inventors found that when the round pipe of the existing exhaust system is rounded, the opening position after the rounding needs to be lifted ma...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a post-treatment exhaust system round pipe rolling support structure to solve the problem that when the round pipe of the existing treatment exhaust system is rounded, the opening position after the rounding needs to be lifted manually, which is inconvenient. For operation, an adjustable support and fixing device cannot be added to the rolling equipment to replace manual lifting, and multiple adjustments cannot be realized to meet the problem of rolling the round pipes of the rear exhaust system with different diameters and lengths
