Numerical control pipe bending machine convenient to replace pipe bending mold

Abstract

The invention discloses a numerical control pipe bending machine convenient to replace a pipe bending mold. The machine comprises a machine body, a fixed shaft, a molding mold, a fixed base, an infrared sensor, a rotating arm, the pipe bending mold, a dowel pin, a pressure sensor, a clamping mold, a mandrel and a support frame; the mandrel is arranged on the front surface of a third slide block; the support frame is arranged at the bottom end of the mandrel; the infrared sensor is arranged on the front surface of the fixed base; the pipe bending mold is arranged on the side, near the molding mold, of the top end of the rotating arm; the dowel pin is arranged in a first slide block; and the pressure sensor is arranged at one end of the clamping mold. The machine is scientific and reasonablein structure and safe and reliable in use, is provided with the dowel pin for conveniently disassembling and mounting the pipe bending mold, is provided with the support frame for preventing displacement of the mandrel in pipe bending, is provided with the infrared sensor for reminding users to keep a safe distance from the pipe bending machine, and is provided with the pressure sensor for preventing clamped deformation of steel pipes.

Description

technical field [0001] The invention relates to the field of intelligent numerical control processing, in particular to a numerical control pipe bending machine which facilitates the replacement of pipe bending dies. Background technique [0002] Nowadays, the industry is highly developed, ranging from airplanes and ships to small computers and televisions, all of which have pipe bending structures inside, and pipe bending machines are required for production and processing of pipe bending. [0003] However, the CNC pipe bending machines on the market have the following disadvantages: no positioning pins, it is inconvenient to disassemble and install the pipe bending mold, there is no support frame, it cannot prevent the mandrel from shifting during pipe bending, there is no infrared sensor, and it cannot be used to remind The operator keeps a safe distance from the pipe bender, and there is no pressure sensor, which cannot prevent the steel pipe from being clamped and defor...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that there is no positioning pin, it is inconvenient to disassemble and install the pipe bending mold, there is no support frame, the displacement of the mandrel cannot be prevented when the pipe is bent, and the infrared sensor cannot be installed to remind the user and the pipe bender. Keeping a safe distance, without setting a pressure sensor, can not prevent the problem of steel pipe being clamped and deformed, and proposes a CNC pipe bending machine that is easy to replace the pipe bending die
