Machine tool drag chain selection principles: internal height: select the built-in cable, tubing, trachea, water pipes, etc. in the thickest one as a reference height, plus at least 10% of the height of the space as drag chain internal height. If the overlap is based on the actual height after the overlap as the reference height. Inner width: choose some thick cables, tubing, trachea, water pipes, etc. , the sum of its outer diameter as a drag chain width of reference, and leave at least 10% of the width of the puzzle degree space. Bending radius: select built-in cable. The maximum bending radius of the tubing, trachea, water pipe, etc. shall be taken as a reference value and shall keep more than 10% of the space in the towing chain. The laying principle of the built-in cable, tubing, water pipe, and trachea shall keep 15% of the remaining space between the blades, let the built-in cable, tubing, etc. can be free to move in the direction of the radius of the drag chain does not produce chaff migration Ulla Force. Wires with large diameter differences should be laid separately and their weights distributed evenly. Use dividers if necessary. In high speed or high frequency operation, to try to make the wires separate from each other horizontally, do not make each other overlapping, in the cable, trachea, tubing, and more when the recommended use of separators.
Machine tool drag chain uses and characteristics (1) suitable for use in the reciprocating movement of the occasion, to the built-in cable, tubing, trachea, water pipes and other traction and protection. (2) each section of the drag chain can be opened for easy installation and maintenance. Low Noise, wear-resistant, high-speed sports. (3) drag chain has been widely used in CNC machine tools, electronic equipment, stone machinery, glass machinery, door and window machinery, injection molding machine, manipulator, overweight transport equipment, automatic warehouse, etc. . Machine tool drag chain basic parameters (1) material: reinforced nylon, with high pressure and tensile load, good toughness, high elasticity and wear resistance, flame retardant, high and low temperature performance stability, can be used in the outdoor. (2) resistance: Oil Resistance, salt resistance, and a certain degree of acid resistance, alkali resistance. (3) operating speed and acceleration: the maximum speed can be up to 5 m/s, the maximum acceleration can be up to 5 m/s (the specific speed, acceleration depends on the operating conditions) . (4) operating life: under normal overhead conditions, up to 5 million times of reciprocating movement please。
