Abstract

The invention discloses a full-servo numerical control pipe bending machine, and relates to the technical field of pipe bending processing. The device comprises a feeding mechanism, an angle rotatingmechanism, a pipe bending mechanism, a clamping mechanism, a lifting mechanism, a horizontal moving mechanism, a backup plate mechanism and a servo mechanism. According to the pipe bending machine, 8-axis servo control is adopted to complete the movement of different angles and positions, bending machining of any angle and radius can be realized, and machining precision is guaranteed; and meanwhile, a pipe bending die and a feeding clamp can be quickly replaced on the structure, so that the pipe bending machine has a function of welding before bending.

Description

technical field [0001] The invention relates to the technical field of pipe bending processing, and more specifically relates to a full-servo numerical control 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 axis bends. [...
