Description

Technical Field

[0001] The present invention relates to the technical field of rolling machinery, and specifically relates to a guiding device for wire rod rolling line production. Background Art

[0002] A sliding guiding mechanism is installed before and after the rough rolling accident shear of the wire rod rolling line; its functions are as follows:

[0003] First: Accurately introduce the red-hot steel into the accident shear, cut off the defective parts at the head and tail, and at the same time accurately guide the over-cut rolled piece into the rear guiding groove and smoothly enter the rolling mill for rolling.

[0004] Second: Play a "supporting" role during the shearing of the head and tail rolled pieces. When a steel piling fault occurs in the rear area, the accident shear continuously breaks, and the broken short steel can be guided into the scrap steel groove.

[0005] The guiding groove of the accident shear is usually a sliding guiding groove, and the friction form is sliding friction. The size of the red billet is about ф80.0mm. Due to the large size and heavy self-weight of the billet, it is easy to cause friction at the part (bottom) where the bottom of the guiding groove contacts the red-hot steel.

[0006] In severe cases, scratching or wire drawing phenomena occur under the red-hot steel. Especially when producing large specifications (above ф12.0mm), it is easy to cause many small surface scars on the finished wire coil, and these small surface scars are often continuous throughout the bar. It has an impact on the quality of subsequent cold wire drawing processing of spring steel and bearing steel. It is easy to cause spring fracture during spring winding and also poses a safety hazard to production. [[ID=2l]]

[0007] Harm of small surface scars on wire coil to spring steel: Ordinary steel wire rods have low requirements for small surface scars, but for high-quality wire rods such as spring steel and bearing steel, there are very strict requirements for small surface scars and scratches. According to the information feedback and analysis of spring factories and wire drawing factories, the presence of more than 40 small surface scars and scratches on the surface of the finished wire rod will affect the subsequent cold processing procedures, reduce work efficiency, and increase quality risks, such as fracture during spring winding and shortening the service life of the spring. The depth of some small surface scars and light scratches cannot be judged by the naked eye. Therefore, it is urgent to carry out technical transformation on the sliding guiding groove before the rough rolling accident shear of the wire rod rolling line. Summary of the Invention

[0030] Preferably, in the present invention, the hanging groove 21 is a strip-shaped groove; the setting of the strip-shaped groove makes the inner walls of the hanging groove 21 all linear structures. At the same time, in the present invention, the cross-section of the end of the guide roller shaft 5 is rectangular; the guide roller shaft 5 with a rectangular end cooperates with the rectangular structure of the hanging groove 21, which can not only realize the positioning and placement of the roller shaft 1-1, but also prevent the wear-resistant roller shaft 1-1 from being stuck and rotating together with the shaft pin, causing wear and deformation of the hanging ear 2.

[0031] Preferably, a cooling water tank 8 is provided at the lower end of the guiding block 1 in the present invention. The cooling water tank 8 is connected to a cooling water joint 3, and the cooling water joint 3 is connected to a water supply component. A cooling water outlet 3-1 is provided on one side of the guiding block 1 close to the hanging ear 2, and the cooling water outlet 3-1 is communicated with the cooling water tank 8. The cooling water tank 8 disclosed in the present invention is located at the lower end of the guiding block 1, that is, directly punching holes at the lower end of the guiding hole, so that the cooling water tank 8 and the guiding block 1 are integrated. During steel piling, it is impossible to touch the water channel hidden inside the guide groove 101, avoiding damage to the water pipe by the rolled piece 9 and reducing the damage and deformation of the water pipe.

[0032] Preferably, the wear-resistant guide roller 6 in the present invention is connected to the guide roller shaft 5 through a roller bearing 7.
