Problems solved by technology

[0002] The existing traction machine clamps the round rod (pipe) material by manually rotating the hand wheel to make the upper and lower pressure wheels press the traction rod (pipe) material. The clamping is time-consuming, laborious and inefficient; in addition, the The transmission system mostly adopts the chain transmission method, the speed of the tractor is not stable when it is working, and the machine occupies a large area
In addition, the method of turning off the power supply of the tractor motor is used to stop the tractor. After the tractor stops, it needs to start the motor again when it needs to work again. The motor starts so frequently that it directly affects the service life of the motor.

Abstract

The invention discloses a tractor for pulling round bar (pipe), which includes a motor transmission frame (1), a fixation frame (4), an upper press wheel (11), a lower press wheel (11A) and a motor (13). The motor (13) is installed on the motor transmission frame (1); the lower press wheel (11A) is installed on the fixation frame (4), output axel of the motor (13) is connected with rotary axel ofthe lower press wheel (11A) by the transmission mechanism (A); the upper press wheel (11) is mounted on a mobile frame (6) which connects with a lifting and pressing mechanism (B), the lifting and pressing mechanism (B) includes a spring (7), a guide column (8), a fixation plate (9) and a piston lifting cylinder (10), wherein the fixation plate (9) is connected with the mobile frame (6) by the guide column (8) equipped with the compression spring (7), the cylinder body of the piston lifting cylinder (10) is fixed on the fixation plate (9), and piston bar of the piston lifting cylinder (10) isconnected with the mobile frame (6). The tractor can fast and conveniently pull bar (pipe), can realize pulling motion with stable and non-shake line speed, and can make the pulled round bar (pipe) stop without turning off the motor.

Description

Technical field: [0001] The invention relates to a pulling machine for pulling round rods (pipes) and belongs to the transformation technology of the pulling machine used for pulling round rods (pipes). Background technique: [0002] The existing traction machine clamps the round rod (pipe) material by manually rotating the hand wheel to make the upper and lower pressure wheels press the traction rod (pipe) material. The clamping is time-consuming, laborious and inefficient; in addition, the The transmission system mostly adopts the chain transmission method, the speed of the tractor is not stable when it is working, and the machine occupies a large area. In addition, when the tractor is stopped, the power supply of the tractor motor is turned off. After the tractor is stopped, the motor must be started again when it needs to work again. The motor is started so frequently that it directly affects the service life of the motor. Invention content: [0003] The purpose of th...
