A pipe bending machine for processing pipe fittings for automobile production and its use method

Abstract

A pipe bending machine for pipe fitting machining for vehicle manufacturing comprising a housing (1), a helical lifting device (2), and a rotating plate (3). The helical lifting device is mounted in the housing. The helical lifting device comprises a lead screw (201). A stepped bending die (4) is rotatably connected to a top end of the lead screw. The rotating plate comprises a rotating die (9) and a fixed frame (10). The rotating die comprises a polygonal plate (901) and a holding die (902). The stepped bending die comprises a stepped column (5) and a transmission cylinder (6). Multiple annular recesses (502) having different diameters are separately axially provided on a peripheral side surface of the stepped column. A use method for the pipe bending machine comprises: the helical lifting device driving the stepped bending die to move vertically, rotating the rotating die with reference to the fixed frame, holding a pipe fitting firmly by means of the holding die and the annular recess matching the pipe fitting, and bending the pipe fitting by means of the stepped bending die and the rotating plate rotating with the lead screw as the center of rotation. This process improves the replacement efficiency of the stepped bending die and the holding die, reduces working stress of workers, and improves the productivity of the pipe bending machine.

Description

Technical field [0001] The invention belongs to the technical field of pipe benders, and particularly relates to a pipe bender for processing pipe fittings for automobile production and a method of use thereof. Background technique [0002] In daily life, pipe fittings with different twists or bends are often required to meet the actual use and performance requirements of the equipment, so people often use pipe benders to bend pipes of different diameters; and pipe benders are roughly divided into numerical control Pipe benders, hydraulic pipe benders, etc.; and the processing of parts such as oil pipes and exhaust pipes on automobiles also need pipe benders. Because of their simple operation and high work efficiency, pipe benders are important in the manufacturing industry. status. [0003] However, when the existing pipe bender needs to process pipe fittings of different diameters, it is often necessary to manually replace wheel molds and clamps of different sizes according to t...

Problems solved by technology

[0003] However, when the existing pipe bending machine needs to process pipe fittings of different diameters, it is often necessary to manually replace the wheel molds and clamping dies of different sizes according to the size of the pipe fittings, which will increase people's labor pressure and reduce the work of the pipe bending machine. Efficiency; therefore, it is necessary to study a pipe bending machine for pipe fittings processing in automobile manufacturing to improve the replacement efficiency of the wheel die and clamping die of the pipe bender
