Description

Technical Field

[0001] The utility model belongs to the technical field of twisting rollers, and in particular relates to a twisting roller guide device. Background Art

[0002] The twisting roller is installed on the horizontal continuous billet rolling mill, steel section rolling mill and wire rod rolling mill, and is a roller-type steel turning device used to turn the rolled products between the stands.

[0003] In the wire rolling and slitting process, in the "ellipse-circle" hole system, if the rolling mill is flat rolling, a twisting guide is required to twist the material into the round hole. At present, this twisting uses a specific twisting guide. The guide wheel of the twisting guide in the prior art is a flat wheel, that is, two guide wheels with parallel cylindrical structures. When the material needs to be twisted, the angle of the twisting guide needs to be adjusted.

[0004] In the utility model patent with announcement number CN217451507U, a torsion guide is provided, which includes a fixed bracket, a rotating shaft, a first guide wheel, a second guide wheel and a guide wheel bracket. The first guide wheel and the second guide wheel are both composed of a cylindrical section and a truncated cone section. The smaller end of the truncated cone section is connected to one end of the cylindrical section. The first guide wheel and the second guide wheel are rotatably arranged on the guide wheel brackets on both sides and the arrangement directions of the first guide wheel and the second guide wheel are opposite. The guide wheel bracket is fixed at one end of the rotating shaft, and the other end of the rotating shaft is installed in the fixed bracket.

[0005] During use of the above patent, when the red blank enters the first guide wheel and the second guide wheel through the rotating shaft, the red blank will heat the rotating shaft. The rotating shaft is heated and continuously impacted by the red blank, causing the rotating shaft to deform and be damaged after being used for a period of time, and needs to be replaced. Utility Model Content

[0006] In order to solve the problem in the prior art that the rotating shaft is heated and continuously impacted by the red blank, causing the rotating shaft to be easily deformed and damaged after being used for a period of time, the utility model provides a torsion roller guide device, which can cool the tongue tip to prevent the tongue tip from being deformed by the impact of the red blank after being heated.

[0007] The technical solution adopted by the twisting roller guide device of the utility model is:

[0008] A twist roller guide device, comprising two twist rollers arranged up and down and in opposite directions, and a mounting frame for mounting the two twist rollers, the mounting frame being located between the two twist rollers and being detachably connected with a guide frame parallel to the twist roller and including a plurality of guide cavities, and a tongue tip in a trumpet shape facing the rolling groove is arranged at the upper and lower sides of the guide frame corresponding to each guide cavity;

[0009] A cooling cavity is provided in each tongue tip, and both sides of each tongue tip are provided with insert tubes connected with its own cooling cavity, and the insert tubes between the tongue tips corresponding to two adjacent guide cavities are connected through a connecting tube.

[0010] A further improvement of the technical solution of the utility model is that the insert tubes on the tongue tip at one edge far away from the connecting tube are all plugged with water delivery pipes, and the insert tubes on the tongue tip at the other edge far away from the connecting tube are all plugged with water outlet pipes.

[0011] A further improvement of the above technical solution of the utility model is that a first cooling pipe for cooling the rolling groove is arranged on the side of the installation frame facing the rolling groove, and the first cooling pipe is connected to the water outlet pipe located below.

[0012] A further improvement of the above technical solution of the utility model is that a second cooling pipe for cooling the twisting roller is arranged on the side of the installation frame away from the rolling groove, and the second cooling pipe is connected to the water outlet pipe located above.

[0013] A further improvement of the technical solution of the utility model is that a water collecting tank for collecting the water discharged from the first cooling pipe and the second cooling pipe is arranged below the installation frame.

[0014] A further improvement of the above technical solution of the utility model is that sealing blocks for sealing the cooling cavity and having an insert tube are fixedly provided at the positions corresponding to the cooling cavity on both sides of each tongue tip, and a through hole is opened at the position corresponding to the insert tube of each sealing block.

[0015] A further improvement of the above technical solution of the utility model is that each twisting roller comprises a roller shaft hinged to the mounting frame, and a plurality of roller bodies in a frustum shape fixedly sleeved on the roller shaft.

[0016] A further improvement of the above technical solution of the utility model is that the tongue tip located at the bottom extends downward to the bottom of the rolling groove, and one end of the rolling groove close to the tongue tip is in contact with the tongue tip.

[0017] Due to the adoption of the above technical solution, the technical advances achieved by the utility model include:

[0018] The utility model provides a water delivery pipe, which can be used to introduce clean water into the cooling chamber through the insert pipe. The clean water entering the cooling chamber can absorb the heat on the tongue tip, thereby keeping the temperature of the tongue tip within a certain range, and preventing the tongue tip from being deformed by the impact of the red blank after being heated.

[0019] Through the water outlet pipe provided in the utility model, the clean water in the cooling chamber can be input into the first cooling pipe and sprayed toward the rolling groove, thereby cooling the rolling groove at the same time to prevent the rolling groove from being deformed and damaged after being heated; at the same time, the water outlet pipe in the utility model can also input the clean water in the cooling chamber into the second cooling pipe and spray it toward the torsion roller, thereby cooling the torsion roller to prevent the torsion roller from being heated and deformed under the impact of the red blank during the transportation of the red blank, thereby extending the service life of the torsion roller.

[0020] In the utility model, since the tongue tip located at the bottom extends downward to the bottom of the rolling groove, and the end of the rolling groove close to the tongue tip contacts the tongue tip, the red blank conveyed from the rolling groove can directly enter the guide cavity through the tongue tip; compared with the case where the tongue tip is not in contact with the rolling groove, when the red blank is conveyed to the tongue tip after being output from the rolling groove, the end of the red blank is easy to hit and twist the tongue tip, causing more production accidents, resulting in low output and reduced yield rate. Accordingly, the utility model can prevent the end of the red blank from hitting and twisting the tongue tip, prevent production accidents, and improve output and yield rate.
