An automatic 9-13m stainless steel composite plate straightening machine

Abstract

The invention discloses a novel automatic straightener for 9 to 13-meter stainless steel composite boards. The novel automatic straightener comprises a rack (1), and multiple upper straightening rolls (2) and multiple lower straightening rolls (3) which are horizontally and parallelly arranged on the rack (1), wherein multiple groups of upper back-up rolls (4) are arranged on the rack above the multiple upper straightening rolls (2); multiple groups of lower back-up rolls (5) are arranged on the rack below the multiple lower straightening rolls (3); multiple hydraulic cylinders (6) are longitudinally arranged above every two to three groups of upper back-up rolls (4); rising and lowering adjusting devices (7) are arranged below the lower straightening rolls; all the upper straightening rolls and the lower straightening rolls are connected with a power device; the power device comprises a reducer (8), commutators (9) and universal joints (10) which are sequentially connected; the universal joints (10) are connected with the tail ends of the upper straightening rolls and the lower straightening rolls; and position adjusting devices (11) are arranged at the two end parts of each straightening roll.

Description

technical field [0001] The invention relates to a hot-rolled stainless steel composite plate straightening equipment, in particular to an automatic 9-13 meter stainless steel composite plate straightening machine. Background technique [0002] Since the hot-rolled stainless steel clad plate is a metallurgical combination of two different metals through rolling, dissimilar metals must have internal stress after rolling due to different thermal expansion coefficients and different elongations, and the longitudinal stress can be removed by a general cold straightening machine , but the transverse stress is difficult to break, and only the transverse straightening machine can be used for stress breaking. The current horizontal straightening is three rollers, that is, two upper straightening rollers and one lower straightening roller, which are arranged in an inverted "pin" shape, which effectively solves the problem that the lateral stress of the stainless steel composite plate ...

AI Technical Summary

Problems solved by technology

It has been found in practical applications that the straightening machine can only achieve one-time straightening for austenitic stainless steel clad plates or martensitic stainless steel clad plates. Composite boards that need to be straightened multiple times need to be connected in parallel with multiple straightening machines, resulting in a huge mechanism, high cost, and complicated process. In addition, only three straightening rollers can be guaranteed to be in working condition during the straightening process, which reduces the risk of straightening. The working efficiency of the machine increases the production cost
