Description

Drag chain with ripple bending radian Technical Field The utility model relates to the technical field of drag chains, in particular to a drag chain with a corrugated bending radian. Background In the industry at present, automatic production equipment is widely used, cables are used for driving equipment to move to indispensable component parts, and in the moving process of moving parts of the equipment, the cables are required to be dragged to move, so that electric signals or power can be timely transmitted to the cables, and therefore, the cables dragged to move together are required to be protected. The drag chain is a component used for installing the cable in the drag chain to protect the cable, and the drag chain can be dragged to carry out the follow-up operation together in the moving process of the moving component, so that the condition that the cable is dragged, worn and intertwined is avoided. At present, in the running process of the drag chain, as shown in fig. 1, the cable is arranged in the drag chain, one end or two ends of the drag chain along the length direction are fixed on the equipment, wherein the two ends can be static, or one end is static, the other end moves, and both ends can also move, under the condition of movement, the lower end of the drag chain deflects towards one direction with less than the preset curvature, in fig. 1, one end of the drag chain is fixed at the point O, the other end is fixed at the point A, the point O is fixed, the point A moves along with the equipment, and flexible bending is carried out at one end by taking R as a radius, so that the drag chain can flex to the point B. For example, in chinese patent publication No. CN222351314U entitled dust-free drag chain case of bellows, adjacent corrugations above the corrugations are mutually abutted at the position where bending occurs, so that the radius dimension of the bending portion is limited when flexible bending occurs, at this time, the larger the radius dimension, the larger the internal stress generated by the bending portion during the process of dragging the cable, that is, the worse the carrying capacity and tensile capacity. Therefore, a new solution is needed to solve the above-mentioned problems.
