Problems solved by technology

[0004] Although the section steel straightening machine simplifies the structure to a certain extent and reduces the investment cost and operating cost, but because the section steel straightening machine still adopts the traditional archway structure, the stress line transmitted by it is long, and it is difficult to achieve a large machine frame. Rigidity, often need to increase the structural size of the rack, so that the weight of the rack is heavy, the structure is cumbersome, and the cost is high

Abstract

The invention discloses a short-stress-path multi-roller straightener, which comprises a frame, a roller system, bearing blocks and a pull rod. The bearing blocks are arranged at one end or both ends of the roller system. The roller system comprises an upper straightening roller unit and a lower straightening roller unit. The bearing blocks include upper bearing blocks and lower bearing blocks respectively corresponding to the upper straightening roller unit and the lower straightening roller unit. The upper bearing blocks are respectively connected with the two adjacent lower bearing chokes through the pull rod, and the upper bearing blocks and / or the lower bearing blocks are in movable fit with the pull rod in the axial direction of the pull rod. A roller gap adjusting device which affects the pull rod is correspondingly arranged on the bearing blocks. The short-stress-path multi-roller straightener is not only simple in structure but compact in structure, light in weight and low in costs by utilizing the features of short stress path and high rigidity of the short-stress-path principle.

Description

technical field [0001] The invention belongs to the technical field of metallurgy and relates to a straightening machine, in particular to a short stress line multi-roller straightening machine. Background technique [0002] Since the short stress line concept in mechanics was put forward, it has been widely used in short stress line rolling mills. The short stress line rolling mill has a shorter stress line than the same specification of the archway rolling mill, so its elastic deformation is small and the rolling mill rigidity is high. It has been widely used in the production of online rods, etc. [0003] But the existing multi-roller straightening machine, as the Chinese patent that the patent number is CN200920010373.1 discloses a kind of section steel straightening machine, comprises casing, is located at the upper straightening roller shaft group in this casing, the lower straightening roller shaft group, the upper straightening roller connected with the upper straig...
