Description

Technical Field

[0001] The invention belongs to the technical field of throw - oil rings, and particularly relates to an anti - slip sealing structure of a throw - oil ring and an implementation method thereof. Background Art

[0002] The roll box of a high - speed wire mill is a core unit for high - speed wire production, which plays a very important role in product quality and output. The roll shaft and the roll box are connected through a contact - type sealing structure. The sealing structure includes an inner throw - oil ring, a double - lip seal, and an outer throw - oil ring. The sliding surface of the inner throw - oil ring protrudes, while the sliding surface of the outer throw - oil ring is concave with a groove. There is a double - lip seal between the two docking surfaces. The outer throw - oil ring is fixed on the roll box, which is not only connected to the inner throw - oil ring through the double - lip seal but also plays a load - bearing role for the roll shaft.

[0003] In high - speed wire production, the high - speed rotation of the roll shaft causes intense friction between the double - lip seal and the sliding surface of the outer throw - oil ring. In traditional high - speed wire and bar non - twisting rolling mills, the installation and fixation of roll rings basically use the taper - sleeve assembly method. It fixes the roll ring on the transmission shaft of the roll box, and relies on extrusion and tension to generate a strong static friction force to ensure the precise positioning of the roll ring. In the assembly of the roll shaft, taper sleeve, and roll ring of this type of structure, the process of pressing the taper sleeve is as follows: the taper sleeve is assembled in place after overcoming the resultant force of the friction force between the taper sleeve and the roll shaft, the friction force between the roll ring and the taper sleeve, and the axial component of the normal pressure exerted by the roll shaft on the taper sleeve under the action of axial pressure, forming a force balance.

[0004] During rolling, the high - speed passing of the wire rod will cause slight loosening of the roll ring, thereby reducing the axial support force of the throw - oil ring, causing the throw - oil ring to rotate, accelerating the wear of the outer throw - oil ring, especially its sliding surface, and reducing the service life of the throw - oil ring. The rotation of the throw - oil ring will also cause the throw - oil ring to slip onto the roll shaft, increasing the friction between the throw - oil ring and the roll - shaft shoulder, wearing the shaft plane, and increasing the risk of shaft breakage. If the surface finish of the sliding surface of the outer throw - oil ring is not high, it will damage the double - lip seal, reduce the service life of the double - lip seal, and cause water to enter the roll box.

[0005] These problems will cause serious consequences for steel production: the entire production line will stop production, affecting steel output; the metallographic structure of the produced wire rod will be uneven, the size will be deformed, or steel breakage will occur. Summary of the Invention

[0006] The purpose of the invention is to provide an anti - slip sealing structure of a throw - oil ring to solve the problems raised in the above - mentioned background art. An anti - slip sealing structure of a throw - oil ring provided by the invention has the characteristics of enhancing the service life of accessories such as the throw - oil ring, roll shaft, and double - lip seal.

[0023] 1. In the present invention, a second groove is provided on the contact surface between the outer thrower ring and the roll ring, and a corrugated spring is provided inside the second groove.

[0024] 2. In the present invention, a first groove is provided on the contact surface between the outer thrower ring and the roll ring and outside the second groove, and an O-ring is provided inside the first groove. When the shoulder of the roll shaft is worn due to the friction between the inner thrower ring and the shoulder of the roll shaft, sealing is achieved through the O-ring to realize the functions of waterproofing and dustproofing, avoiding impurities from entering between the roll ring and the taper sleeve, and thus avoiding the roll box from entering water due to the dropping pressure of the taper sleeve.
