Problems solved by technology
At present, in the stretching production of large-scale metal round link chains in China, the clamping method of the circular link chain is manual or semi-automatic. Although the advanced automatic stretching equipment imported from abroad adopts the automatic clamping method to complete, but The price of imported equipment is very high, and it is difficult to repair and replace spare parts, which is unbearable for ordinary manufacturers

The invention relates to an automatic scatheless drawing device for a metal round link chain. Two drawing oil cylinders are arranged on a fixed seat, a piston rod end of each drawing oil cylinder is connected with a movement pulley through a flange, and a movement passage for the metal round link chain is arranged on the foundation and the movement pulley; and one clamp chain mechanism is arranged on the fixed seat and is used for drawing one link of the metal round link chain, and the other clamp chain mechanism is arranged on the movement pulley and is used for drawing the other link of the metal round link chain. The automatic scatheless drawing device has a simple structure, is convenient to operate, and works reliably; actions of all mechanisms are driven by the hydraulic oil cylinders, large power can be obtained, and stable transmission and accurate starting and stopping can be realized; and the device can fully automatically draw the metal round link chain, the shape of a cavity of a clamp chain head is matched with the appearance of the link end, the round link chain is not extruded during drawing and stressing, and product quality and production efficiency can be greatly improved.
Description
technical field [0001] The invention belongs to the technical field of production and processing of metal circular chains, and relates to a stretching machine for metal circular chains, in particular to a metal circular chain that can ensure that the metal circular chain will not be damaged during the automatic stretching production process. Automatic stretching device without damage to the chain. Background technique [0002] In the fully automatic stretching production process of large-scale metal round link chains, after the round link chains are sent to the stretching station, the clip chain device can accurately clamp the round link chains, and there should be no damage to the round link chains. Extrusion scars to ensure the tensile strength of the round link chain. At present, in the stretching production of large-scale metal round link chains in China, the clamping method of the circular link chain is manual or semi-automatic. Although the advanced automatic stretchi...
