Description

Technical Field

[0001] The utility model relates to the technical field of high-speed wire production, in particular to a light-wear universal guide groove for a high-speed wire finishing rolling water-penetrating box. Background Art

[0002] Generally, in the metallurgical steel rolling high-speed wire industry, water tanks and guide grooves are designed after the finishing mill to control the organization and performance of the high-speed wire products. After the finished wire passes through the guide groove and enters and exits the water tank for rapid cooling, although the surface temperature of the wire is reduced, the core temperature is still between 700-750℃. When the high-speed wire passes through the water tank and exits the guide groove, the guide groove is generally fixed to the water tank by bolts. When the high-speed and high-temperature wire passes through the guide groove, due to the uneven cooling on site, the high-speed wire becomes eccentric when passing through the guide groove, causing the wire to rub against the guide groove wall, often causing abnormal wear and scrapping of the guide groove. When the wear is severe, there may be a risk of steel clamping, and there are great safety hazards.

[0003] In the actual production process, the high-speed wire channel, guide groove or equipment after the loop is easily worn out, and manpower is required to frequently check its wear condition. If it is seriously worn, it needs to be replaced in time, which takes up a lot of manpower and wastes a lot of spare parts. It may even cause steel piling up on the production line wire, causing waste of equipment and steel. This is especially true for the inlet and outlet guide grooves of the water tank after the finishing mill. Since its speed is very high, reaching 90m / s, if the wire is eccentric, it will wear the fixed guide groove very quickly. Utility Model Content

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] See also Figure 1 The utility model provides a technical solution: a light-wear universal guide groove for a high-speed wire finishing water tank, comprising a guide groove concrete foundation 1 and a light-wear universal guide groove 4 arranged on the top.

[0014] Pins 12 are provided on both sides of the outlet end of the light-wear universal guide groove 4. The pins 12 are arranged on the pin universal wheel bracket 11, and the pins 12 are at the same height as the axis of the light-wear universal guide groove 4, and the adjustment amount is controlled within 1.5-2mm (high-line center deviation range) to ensure that the center of the high-speed wire is within the specified range and prevent the adjustment amount from exceeding the design and causing steel piling. The pin universal wheel bracket 11 is fixed to the bracket 10 on the guide groove concrete foundation 1 by bolts.

[0015] Four sets of universal buffer mechanisms are evenly arranged around the inlet end of the light-wear universal guide groove 4, including a guide groove square spring frame 3, a buffer sleeve 5, a compression spring 6 and a spring pressure cover 7. The cross-section of the guide groove square spring frame 3 is square and is welded to the guide groove base frame 2.
