Axle tube part straightening device and process method

Abstract

The invention discloses an axle tube part straightening device and a process method, and belongs to the technical field of machining and devices. The straightening device comprises two sets of straightening mechanisms which are mounted on a workbench and are symmetrical left and right, a connecting bar mechanism used for transmitting motion and amplifying force, a hydraulic system used for providing power and a numerical-control system used for controlling and directing, wherein the straightening mechanisms are mounted on the upper part of the workbench; the bottom ends of U-shaped plates in the straightening mechanisms are hinged with the connecting bar mechanism; the connecting bar mechanism is further hinged with the lower end of a table board of the workbench; the connecting bar mechanism is connected to a hydraulic system; and the hydraulic system and electric motors in the straightening mechanisms are connected to the numerical-control system. The process method comprises the following steps: (1), clamping; (2), loading; and (3), unloading. The axle tube part straightening device is high in straightening efficiency, can straighten axle tube parts which are bent in multiple directions once, is simple, is low in cost, can obtain uniform residual stress, and improves mechanical property 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...
