Problems solved by technology

The disadvantages of the hydraulic transmission system are: 1. Since the hydraulic transmission system needs to be driven by hydraulic fluid, and is equipped with hydraulic stations, hydraulic pipelines, etc., it is easy to cause hydraulic oil leakage and pollute the environment; 2. The slider is controlled by the hydraulic cylinder. Movement can only apply force to both ends of the slider, so that the entire slider and the worktable are unevenly stressed, and the slider is prone to deformation during long-term operation; 3. Automatic reset cannot be achieved when the machine tool fails, and the safety factor is low

Abstract

A CNC bending machine belt transmission system, including a fuselage and a slider fixed above the fuselage, a sliding frame on the fuselage below the slider is provided with a workbench, and a number of fixed pulleys are arranged on the fuselage. The workbench is provided with a number of moving pulleys corresponding to the fixed pulley, the body is also provided with a servo motor, the output shaft of the servo motor is provided with a motor pulley, and the motor pulley is connected to There is a transmission belt, the transmission belt is alternately wound with the fixed pulley and the dynamic pulley and the end is fixed with the fuselage. The belt transmission system of the bottom-moving numerical control bending machine of the present invention has the advantages of stable transmission, fast response, high transmission precision, uniform force on the workbench, and small deformation.

Description

technical field [0001] The invention relates to a belt transmission system of a numerically controlled bending machine. Background technique [0002] In the prior art, the main transmission system of the bending machine is generally divided into two types: mechanical transmission and hydraulic transmission, while the numerical control bending machine generally adopts hydraulic transmission. The hydraulic transmission system includes a fuselage, a workbench and a slider mounted on the fuselage, and hydraulic cylinders for driving the slider to slide up and down along the workbench are respectively provided on both sides of the fuselage. The shortcomings of the hydraulic transmission system are: 1. Since the hydraulic transmission system needs to be driven by hydraulic fluid, and is equipped with a hydraulic station, hydraulic pipelines, etc., it is easy to cause hydraulic oil leakage and pollute the environment; 2. The slider is controlled by the hydraulic cylinder. Movement...
