Embodiment 3

[0046] refer to figure 1 and figure 2 , the control system of the present invention adopts 8 servo motors to respectively control the feeding servo motor, bending pipe servo motor, leaning plate servo motor, clamping servo motor, lifting servo motor, horizontal movement servo motor, angle rotation servo motor, and follow-up servo motor . The feeding servo motor drives the feeding shaft X to do the feeding movement. The pipe bending servo motor drives the pipe bending axis Y to perform the rotating pipe bending action. The backing plate servo motor drives the backing plate to move radially along the pipe material, and fixes the pipe material between the pipe bending mold 10 and the backing plate (the bending of the pipe is equal to the reverse force when the pipe is bent and deformed). The clamping servo motor drives the clamping shaft to clamp the pipe on the pipe bending die 10 . The lifting servo motor drives the lifting shaft B to move up and down to adjust the positio...

Abstract

The invention discloses a numerical control pipe-bending machine control system, and relates to the technical field of pipe bending machining. The numerical control pipe-bending machine control systemcomprises a central controller, external inputting equipment, external outputting equipment and a pipe-bending machine executing part. The pipe-bending machine executing part comprises a feeding servo mechanism, an angle rotating servo mechanism, a pipe-bending servo mechanism, a clamping servo mechanism, a lifting servo mechanism, a horizontal moving servo mechanism, a plate backing servo mechanism and a follow-up servo mechanism. According to the numerical control pipe-bending machine control system, moving at different angles and positions is completed through eight-axis servo control, bending machining at any angle and radius can be achieved, and the machining precision is guaranteed; and meanwhile, quick replacing of a pipe-bending mold and a feeding clamp can be structurally achieved, and thus, a pipe-bending machine has the function of welding prior to bending.

Description

technical field [0001] The invention relates to the technical field of pipe bending processing, and more specifically relates to a control system of a numerically controlled pipe bending machine. Background technique [0002] In some industrial products, some pipe profiles need to be processed into unique shapes by pipe bending machines, and pipe bending machines are the main equipment for completing this work. Pipe bending machine is a machine for bending tubular materials and plates. It is widely used in engineering and manufacturing. Its main uses are shipbuilding, bridges, tables and chairs, furniture and home appliances, etc. At present, hydraulic pipe bending machines are mainly used in the market, and their control systems are mostly program-controlled systems, which control various hydraulic valves or hydraulic motors. The basic characteristics of the ordinary hydraulic pipe bender in the axial structure are 3 axes, the Y axis feeds, the B axis rotates, and the C ax...
