technical field [0001] The invention relates to a tripping device, in particular to a cold rolling spinning and dumping tripping device, which belongs to the technical field of cold rolling equipment. Background technique [0002] The production and rolling methods of steel wire rods include cold rolling production and hot rolling production. The production temperature of the hot rolling production line is above the crystallization temperature of the material, and the temperature of the cold rolling production line is below the crystallization temperature. In the production of wire rod, it needs to go through the spinning process of the wire laying machine. The wire rod is in a spiral shape when the wire laying machine is spinning.

Problems solved by technology

[0002] The production and rolling methods of steel wire rods include cold rolling production and hot rolling production. The production temperature of the hot rolling production line is above the crystallization temperature of the material, and the temperature of the cold rolling production line is below the crystallization temperature. In the production of wire rod, it needs to go through the spinning process of the wire laying machine. The wire rod is in a spiral shape when the wire laying machine is spinning. In the hot-rolled wire rod, because the production temperature is above the crystallization temperature, the temperature of the product just after spinning is very high. The spiral-shaped wire rod is very flexible, and it will be dumped on the transmission line immediately after spinning out. In the production of cold-rolled wire rods, the cold-rolling temperature is relatively low, and the temperature after the wire rod is spouted is relatively low. The rigidity of the wire rod just after spinning out Larger, the silk will often be kept in the vertical direction when it comes out, it will not immediately fall down on the wire transmission line, and it will not be transported backwards immediately with the transmission line, which will increase resistance to the spinning machine and cause blockage As a result, continuous large-scale production of wire rod spinning cannot be achieved. To solve this problem, the cold-rolled wire rod production line often adopts the method of increasing the wire spinning temperature, but only to improve the flexibility of the wire rod. The flexibility increases and the rigidity decreases to meet the requirement that the wire can be dumped in time. This method needs to increase the spinning temperature. On the one hand, it will cause a large energy consumption and increase the cost. Moreover, increasing the spinning temperature will affect the material of the wire. Characteristics, such as strength, hardness and other performance indicators, bring difficulties to the quality control of cold-rolled wire rods. In addition, traditional cold-rolled production is often equipped with multiple people to monitor the wire-laying machine in order to solve the problem of continuous production due to the plugging of silk. The working conditions increase the manpower input and increase the production cost of the wire rod. It is a long-term troubled technology in the wire rod cold rolling technology to dump the wire rod out of the wire laying machine in time without increasing the wire rod spinning temperature. The problem of personnel is also the main problem affecting the continuous production of cold-rolled wire rods. For a long time, cold-rolled technicians have been looking for a technical solution that can enable the normal transmission of wire rods from spinning at a lower spinning temperature.
