High-precision wheelchair armrest fixing frame pipe bending device and working method

Abstract

The invention provides a high-precision wheelchair armrest fixing frame pipe bending device and a working method. The high-precision wheelchair armrest fixing frame pipe bending device comprises a bottom plate and a bending device body, and the device is characterized in that the bending device body comprises a motor, a rotor shaft of the motor penetrates through the bottom plate and is provided with a fixing base and an upper die wheel, the fixing base is fixedly connected with the rotor shaft, and a bending disc is rotationally connected with a rotating shaft; a window is formed in the lower end of the fixing base, a sliding block is arranged in the window, a first rotating shaft is arranged on the sliding block, a lower die wheel is rotationally connected to the first rotating shaft, a hydraulic cylinder is arranged at the lower end of the fixing base, and a piston rod of the hydraulic cylinder upwards penetrates through the bottom of the window to be connected with the sliding block. The upper die wheel and the lower die wheel can be replaced, and annular grooves of different specifications can be suitable for bending pipes of different specifications; the upper die wheels with different diameters can meet the requirements of different bending angles; and the high-precision wheelchair armrest fixing frame pipe bending device is convenient to adjust and use.

Description

technical field [0001] The invention belongs to the technical field of wheelchair manufacturing, and in particular relates to a high-precision wheelchair armrest fixing frame pipe bending device and a working method. Background technique [0002] In the manufacturing of wheelchairs, the wheelchair frame is generally made of bent pipes, and the purchased pipes are generally cylindrical and linear, and they need to be bent based on the actual situation when using them. The existing pipe bender has complex bending operations and is inconvenient to use; the structural design is complicated, which is not conducive to increasing production costs, and is not conducive to later maintenance and repair. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a high-precision wheelchair armrest fixing frame pipe bending device and working method, which has a simple structure design and is easy to manufacture and use; the upper and lower...
