Background

A certain distance exists between the primary cooling water tank of the production line of the high-speed wire rod factory and the front flying shear of the finishing mill, so a plurality of rolling bodies can be installed. The rolling body is contacted with the red steel through rolling friction of the roller, so that the wire rod is prevented from being rubbed to generate scratches when passing through.

The rolling element generally adopts oil-gas cooling in the use, cools off the gyro wheel part with the contact of red steel through two water-cooling nozzle of welding on the rolling element, ensures not burnt loss with the part of red steel contact, guarantees that wire rod production goes on steadily.

Currently, as shown in fig. 5 and 6, a hole is usually formed directly in the main water pipe, and the roller is cooled by a small section of bent copper pipe. However, since the rolling elements need to be replaced and adjusted when wires of different specifications are produced, the copper tubes increase the difficulty of replacement and adjustment, and meanwhile, after the rolling elements rotate, the copper tubes need to be respectively adjusted one by one to ensure that the rolling elements are cooled; in addition, the copper pipe is not firmly fixed to the main pipe because of the need of disassembly and adjustment, and is easy to fall off when in use.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems that the existing rolling body water-cooling nozzle has high difficulty in replacing and adjusting the rolling body and is easy to fall off when in use, and provides the high-efficiency rolling body cooling nozzle which is firm to mount, convenient for cooling the rolling body after rotating and does not obstruct the replacement of the rolling body.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a high-efficiency rolling element cooling nozzle comprises a group of rolling element rollers connected to a roller seat, wherein a rolling element passing pipe is arranged on the front side of each rolling element roller, the rolling element rollers and the rolling elements are connected to a rolling element support through the pipes, and the rolling element support is connected to a bottom plate through bolts;

the roller seat is also connected with a group of guide pipes, the guide pipes are arranged on the upper side and the lower side of the rolling body passing pipe, a group of nozzle openings are arranged on the guide pipes, the nozzle openings are arranged right opposite to the rolling body rollers, one end of each guide pipe is arranged to be a closed end, the other end of each guide pipe is arranged to be an open end, the open ends of the guide pipes are fixedly connected with hoses, the hoses are further connected with a water distributor, and the water distributor is connected with a main water pipe so as to be used for distributing water in the main water pipe to each hose and each guide pipe through the distributor to cool the roller.

Further, the two ducts are provided in parallel with each other on the upper and lower sides of the rolling element passage tube.

Further, the nozzle openings are arranged in rows and are uniformly arranged on the guide pipe along the axial direction of the guide pipe.

Furthermore, an internal thread is arranged in the opening end of the conduit and is matched with the external thread of the hose, so that the conduit and the hose can be firmly connected.

Furthermore, each nozzle opening is connected with a nozzle which is matched with each other, and the nozzles are arranged opposite to the rolling body rollers.

Compared with the prior art, the technical scheme of the utility model has the advantages that:

(1) the device of the utility model ensures the cooling of the rolling body and is more convenient for replacing the rolling body;

(2) the condition that the angle and the position of the traditional copper pipe need to be adjusted one by one after the rolling body is replaced is avoided, the working efficiency is improved, and the cooling of the rolling body after rotation is ensured;

(3) the guide pipe is directly connected to the roller seat, and the roller is cooled through the nozzle opening on the guide pipe, so that the guide pipe is not easy to fall off in use;

(4) the device provided by the utility model prolongs the service time of the rolling element on the wire, reduces the surface scratches of the finished wire rod and improves the production quality.
