Abstract

The invention discloses a straightening device and a process method for shaft tube parts, which belong to the technical field of mechanical processing and devices. The straightening device includes two sets of left and right symmetrical straightening mechanisms installed on a workbench for transmitting motion and amplifying The connecting rod mechanism for power, the hydraulic system for power supply and the numerical control system for controlling and directing; the straightening mechanism is installed on the upper part of the workbench; the bottom end of the U-shaped plate in the straightening mechanism is hinged with the connecting rod mechanism, and the connecting rod The mechanism is also hinged with the lower end of the worktable; the connecting rod mechanism is connected with the hydraulic system; the hydraulic system and the motors in the two sets of straightening mechanisms are connected with the numerical control system; the process methods include: ① clamping, ② loading, ③ unloading. The invention has high straightening efficiency, can straighten shaft tube parts deflected in multiple directions at one time, has simple equipment, low cost, can obtain uniform residual stress, and improves the mechanical properties of products.

Description

technical field [0001] The invention relates to the technical field of mechanical processing and devices, in particular to a straightening device and process method for shaft tube parts. Background technique [0002] The iron and steel industry is one of the pillar industries of the national economy and has played an irreplaceable role in the process of my country's industrial modernization. As an important steel product, shaft tube parts are widely used in machinery, shipbuilding, petrochemical and other industries. With the expansion of the production scale of shaft tube parts, people have higher and higher precision requirements for shaft tube products. , precision forming has attracted more and more attention from academia and steel companies. [0003] Due to heat treatment process, uneven material properties, and processing parameters of shaft parts, the straightness of the shaft often exceeds the standard; tube parts are affected by factors such as forming equipment a...
