Description

Technical Field

[0001] This utility model relates to the field of horizontal continuous casting technology for non-ferrous metals, specifically a modular and detachable traction ingot head. Background Technology

[0002] In the horizontal continuous casting process of non-ferrous metals, the traction ingot head device is the core component for billet formation, and its performance directly affects the continuity of production and product quality. Currently, the industry generally uses an integral traction ingot head made of pure copper. However, the traction ingot heads currently in use have certain problems. The yield strength of copper material drops sharply under the initial continuous casting conditions, making it prone to minor deformation that is irreversible and leads to scrap. Traditional integral structures require special tools for disassembly, and each maintenance takes a long time. Not only is the manufacturing cycle of copper ingot heads long, but high-temperature adhesion also causes some spare parts to be damaged during disassembly.

[0003] Therefore, a novel modular and detachable traction spindle head is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a modular and detachable traction spindle head to solve the problems mentioned in the background art, such as the need for special tools to disassemble the traditional integral structure, the long maintenance time, the long manufacturing cycle of copper traction spindle heads, and the damage to some spare parts during disassembly due to high-temperature adhesion.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular detachable traction spindle head, comprising a traction spindle head body, wherein an outer shell is sleeved and fixed to the left side of the traction spindle head body, and a detachable component is provided inside the traction spindle head body; The detachable component includes a dovetail groove. An internal groove is recessed inward at the center of the left side of the traction spindle head body. The dovetail groove is located on the left side inside the traction spindle head body and surrounds the outside of the internal groove. A first fixing seat is sleeved and fixed on the right side of the traction spindle head body. An inner connecting seat is sleeved and fixed on the right side of the first fixing seat. A second fixing seat is sleeved and fixed on the right side of the inner connecting seat. As a further technical solution of this utility model, the top and bottom ends of the first fixing seat, the inner connecting seat and the second fixing seat are in the shape of a "U".

[0006] As a further technical solution of this utility model, a ring of hard alloy substrate is fixedly connected to the surface of the outer shell, and a ring of tungsten carbide hard alloy layer is fixedly connected to the inner end of the outer shell.

[0007] As a further technical solution of this utility model, a ring of aluminum silicate ceramic fiber paper is fixedly connected to the inner end of the tungsten carbide hard alloy layer.

[0008] As a further technical solution of this utility model, a connection port is provided through the right side of the traction spindle head body, and an inner cover is fixedly connected to the inner end of the connection port, the inner end of the first fixed seat, the inner connecting seat and the second fixed seat.

[0009] As a further technical solution of this utility model, an auxiliary sleeve is fixedly fitted to the outside of the connection port.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the modular detachable traction spindle not only realizes the detachable function and the thermal stability function, but also realizes the deformation prevention function; (1) By setting up an internal groove, a dovetail groove, a first fixed seat, an inner connecting seat and a second fixed seat, the dovetail groove is located inside the left side of the traction spindle head body and is the core load-bearing module. It plays a role in positioning and fixing the traction rod, ensuring that the structure can be flexibly disassembled and used, facilitating disassembly and maintenance in the later stage, greatly reducing the maintenance time required. By utilizing the standardized characteristics of the connection port, it can be flexibly replaced, expanding the scope of application, and is easy to lock and fix, effectively preventing it from falling off during use. The traditional integrated structure is divided into multiple modules, which is convenient for disassembly and use. It breaks through the low disassembly efficiency and equipment wear caused by the integrated structure, realizes the modular replacement of key components, and reduces the life cycle cost of the traction spindle head body. (2) By setting up an outer shell, a hard alloy substrate, a tungsten carbide hard alloy layer and an aluminum silicate ceramic fiber paper, the hard alloy substrate, the tungsten carbide hard alloy layer and the aluminum silicate ceramic fiber paper adopt a gradient composite layer design to ensure that the high temperature contact surface is in an intact state for a long time, avoid deformation caused by continuous high temperature contact, avoid damage to the main body of the traction spindle, and reduce the scrap rate. (3) By setting up a connection port, an auxiliary sleeve and an inner cover, the inner cover is added to ensure that the internal space of the first fixed seat, the inner connecting seat and the second fixed seat forms a gap, thereby achieving thermal expansion self-compensation and improving the connection strength between the structures. This prevents the structure from loosening or even breaking after deformation, improves the safety of use, and prevents the problem of irreversible plastic deformation. Attached Figure Description
