Description

Technical Field

[0001] This utility model relates to the technical field of wire production equipment, specifically to a rapid air cooling device for a vertical wire winding frame. Background Technology

[0002] In traditional high-speed wire rod production, the wire coils undergo natural cooling on vertical coil frames and PF conveyor chains after coiling and before packaging. The temperature of conventional steel wire rods after coiling is approximately 600-700℃, and the coils need to be naturally cooled to below 400℃ before entering the packaging machine. Because natural cooling is very slow, the coils require at least 40 minutes of cooling to reach this temperature. Therefore, the vertical coil frames and PF conveyor chains need to be designed to be sufficiently long to meet the temperature drop requirements. This results in large equipment investments, a large floor space requirement, and low plant utilization efficiency.

[0003] Therefore, in actual production lines, wire rods are usually not cooled to below 400°C before entering the baling machine. Excessive baling temperature has many drawbacks, such as easily causing unwinding, scalding the wear-resistant plate at the end of the baling machine, resulting in significant spare parts wear. Due to the excessively high temperature of the wire rod during baling, the packaging bags have melted multiple times on site after being put on. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a rapid air cooling device for a vertical wire winding frame, which can effectively solve the problems in the existing technology.

[0006] Technical solution

[0007] This utility model provides a rapid air cooling device for a vertical winding frame of wire rod, including a vertical winding frame structure, which is composed of a rotary roller bed, a four-axis roller bed, and a two-axis roller bed. Cooling fans are installed at the four corners of the vertical winding frame, and cooling air ducts are laid at the bottom of the rotary roller bed, the four-axis roller bed, and the two-axis roller bed. The cooling fans and the cooling air ducts are connected by a main air supply duct. A cooling nozzle is installed on the cooling air duct at 600mm intervals, and each cooling nozzle is equipped with a pressure detection head and a solenoid valve.

[0008] Furthermore, the four sets of cooling air ducts are connected by adapter pipes to form an air duct circulation.

[0009] Furthermore, the top of each cooling air duct is provided with a connecting end at equal intervals. The air-cooled nozzle includes a connecting pipe and the top of the connecting pipe is connected to the end of the solenoid valve. The end of the solenoid valve is fixed to the receiving tube, and the top of the receiving tube is fixedly connected to the nozzle.

[0010] Furthermore, a pressure detection head from a detection device is installed inside the connecting pipe.

[0011] Furthermore, the connecting end and the connecting pipe are engaged and fixedly connected.

[0012] Furthermore, the inner side of the converging tube is funnel-shaped, wider at the bottom than at the top, and a groove is provided at the top of the nozzle.

[0013] Beneficial effects

[0014] In this invention, without extending the length of the vertical core frame and PF transport chain equipment, the wire can be quickly placed into a controlled cooling state after being coiled and placed on the vertical core frame. This invention can reduce the surface temperature of the coiled wire by 60℃-70℃, providing favorable conditions for subsequent packaging and avoiding a series of problems caused by excessively high packaging temperatures. Each air-cooling nozzle can spray cold air individually or together, and the flow rate of the cold air can be controlled by a flow solenoid valve.

[0015] In this device, cooling fans are installed at the four corners of the vertical winding frame, along with cooling air ducts laid at the bottom and air-cooled nozzles spaced 600mm apart, to achieve all-round and uniform cooling of the wire, significantly improving cooling efficiency and ensuring stable cooling quality. Each air-cooled nozzle is equipped with a pressure detection head and a solenoid valve, which can monitor the nozzle pressure in real time and accurately control the airflow, allowing for flexible adjustment according to the cooling needs of the wire and achieving intelligent cooling management, avoiding overcooling or undercooling. The four sets of cooling air ducts are connected by adapter pipes to form an air circulation system, which can improve the utilization rate of cold air, reduce energy waste, and ensure balanced air pressure in each area, further improving the consistency of cooling. The air-cooled nozzles adopt a structure in which the connecting pipe and the cooling air duct are meshed and fixed, combined with the trumpet-shaped design of the coiled tube (smaller at the top and larger at the bottom) and the groove at the top of the nozzle, which not only ensures the stability of the nozzle installation, but also optimizes the cold air ejection shape, enhances the contact effect between the cold air and the wire, and improves the cooling rate.
