Description

technical field [0001] The invention relates to a wire cutting device, in particular to an improved invention of a wire cutting machine. Background technique [0002] In the prior art, the wire cutting machine has the following deficiencies: 1. The wire storage cylinder of the wire cutting machine is driven by a motor when it changes direction in forward and reverse directions and the base of the wire storage cylinder moves left and right, and the motor is directly installed on the wire storage cylinder. On the drum base, one shaft end of the wire storage drum shaft is connected in series with the motor shaft, and then the traveling mechanism is driven by the other shaft end to move. The disadvantage of the above structure is that the vibration and the inertial force of forward and reverse rotation of the motor will affect the wire storage. 2. In order to ensure the cutting quality of the wire cutting machine, the distance between the guide wheel of the upper wire arm of the...

[0002] In the prior art, the wire cutting machine has the following deficiencies: 1. The wire storage cylinder of the wire cutting machine is driven by a motor when it changes direction in forward and reverse directions and the base of the wire storage cylinder moves left and right, and the motor is directly installed on the wire storage cylinder. On the drum base, one shaft end of the wire storage drum shaft is connected in series with the motor shaft, and then the traveling mechanism is driven by the other shaft end to move. The disadvantage of the above structure is that the vibration and the inertial force of forward and reverse rotation of the motor will affect the wire storage. 2. In order to ensure the cutting quality of the wire cutting machine, the distance between the guide wheel of the upper wire arm of the wire cutting machine and the workpiece must be adjusted, and the connection between the guide wheel and the workpiece must be adjusted. The surface of the workpiece is vertical. In the prior art, the lifting device of the upper wire arm guide wheel of the wire cutting machine is composed of a column, an upper wire arm, and a lower wire arm. The adjustment of the distance between the upper wire arm guide wheel and the workpiece is the upper wire arm. In the guide groove of the column, the lifting is driven by the screw transmission. The disadvantages are that the pulling accuracy is poor, the operation is cumbersome, and the structure is not compact; 3. During the continuous cutting and continuous use of the electrode wire of the wire cutting machine, the , electrode wire wear and other factors, the tension force of the electrode wire will gradually lose, which will greatly affect the processing quality of wire cutting, so a tension control device must be installed to control the constant tension of the electrode wire. In the prior art , there is a tension control device with the help of spring thrust, and a tension control device with the help of a cylindrical linear guide and spring thrust, but they all have the defects of complex structure and unstable tension
