Integrated bending forming device for abnormally-shaped tube

Abstract

The invention discloses an integrated bending and forming device for an abnormally-shaped tube, and relates to the technical field of cab structures of various types of engineering machinery, such as an excavator, a loader and the like, in particular to a device for bending and forming the abnormally-shaped tube. The device comprises a working platform, wherein three oil cylinder brackets are connected to the outer side of the working platform; a first hydraulic oil cylinder is connected to the first oil cylinder bracket; a second hydraulic oil cylinder is connected to the second oil cylinder bracket; a third hydraulic oil cylinder is connected to the third oil cylinder bracket; the telescopic end of the second hydraulic oil cylinder is connected with a limiting block; a positioning block is arranged on the other side of the limiting block and connected to the working platform; a cambered groove is formed on one side of the positioning block, which faces the limiting block; and at least five flexible adjustment devices are respectively arranged between the first hydraulic oil cylinder and the second hydraulic oil cylinder as well as between the second hydraulic oil cylinder and the third hydraulic oil cylinder and respectively connected to the working platform. The integrated bending and forming device is convenient, practical, low in cost and recyclable, and can control the size of the abnormally-shaped tube and control the abnormally-shaped tube to be rebounded.

Description

technical field [0001] The invention relates to the technical field of various types of construction machinery, such as excavators, loaders and other cab structures, in particular to a device for bending and forming special-shaped pipes. Background technique [0002] With the widespread use of special-shaped tubes in construction machinery cabs, the overall bending and forming of special-shaped tubes has become a new threshold for its popularization and use. [0003] Due to the difference in the section structure, section thickness and material of the special-shaped tube, as well as the difference in the amount of deformation of the bending forming, the bending springback rate of the special-shaped tube will be different. A batch is completely consistent, resulting in a more difficult control of forming springback. In particular, the most commonly used multi-segment variable arc special-shaped tube in construction machinery cabs, the springback size change of its overall be...
