Flexible roller bend-forming production line

Abstract

The invention relates to a flexible roller bend-forming production line in the field of forming machining devices. The flexible roller bend-forming production line comprises a discharge device, a decoiling device, a shear butt welding device, a forming device, a welding device, a straightening device and a cutoff device. The forming device comprises flat flexible rollers and vertical flexible rollers. An upper roller shaft and a lower roller shaft of each flat flexible roller are each symmetrically sleeved with two shaft sleeves, and the shaft sleeves are in sliding key connection with the corresponding upper roller shafts and lower roller shafts. One end of each shaft sleeve is mounted in a sliding seat through an auxiliary bearing. Transverse adjusting screws are arranged on the front side and the rear side of each sliding seat correspondingly and used for driving the corresponding sliding seat to slide. Upper half rollers are mounted outside the shaft sleeves located on each upper roller shaft, and the two upper half rollers corresponding to each upper roller shaft are arranged symmetrically. Lower half rollers are mounted outside the shaft sleeves located on each lower roller shaft, and the two lower half rollers corresponding to each lower roller shaft are arranged symmetrically. The flexible roller bend-forming production line is low in wear, few in workpiece scratch and low in forming energy consumption, has universality and can be used for welding pipe production.

Description

technical field [0001] The invention relates to a forming processing device, in particular to a production line for roll forming processing of welded pipes. Background technique [0002] In the prior art, there is a roll forming production device, which is mainly used to produce welded pipes, profiles, etc., and the device includes a feeding device, an uncoiling device, a shear butt welding device, a vertical roll forming device, a flat roll forming device, a welding device, straightening device, cutting device and other devices, among which the vertical roll forming device and the flat roll forming device are respectively equipped with multiple passes. Taking the flat roll forming device as an example, its structure mainly includes a base, which is connected to the frame, and two supporting frames are symmetrically arranged on the upper side of the base, and a longitudinal sliding rail is arranged on the supporting frame, and a longitudinal sliding rail is arranged in the l...

Problems solved by technology

The disadvantage is that such roll bending molds are not universal and require a large number of molds of different specifications to meet production requirements, resulting in relatively high manufacturing costs

[0003] The existing roll bending die, that is, the upper roll or the lower roll, itself is a whole. During roll forming, most of the profiles are in contact with the workpiece. Because the radius of gyration at different positions is inconsistent, the line speed is inconsistent Yes, it will cause friction with the workpiece. On the one hand, it is easy to leave scratches on the workpiece, and on the other hand, the mold itself is easy to be worn
