Description

Technical Field

[0001] This utility model relates to the field of steel cord production technology, and more specifically to steel wire surface grinding equipment. Background Technology

[0002] In the production of steel cord, surface cleaning of the steel wires is a crucial step. During processes such as hot rolling, heat treatment, and lead quenching, a dense layer of iron oxide scale forms on the surface of the steel wires. This scale is very hard and brittle, and its bond with the base metal is weak. Since the primary application of steel cord is as a reinforcing material embedded in tire rubber, a strong and durable bond between the steel wires and the rubber is essential for tire safety, durability, and performance. Therefore, removing the scale and contaminants to expose a fresh, active metal surface is critical to the quality of subsequent brass plating.

[0003] For cleaning the oxide scale on the surface of steel wire, the existing technology usually uses abrasive belts to grind the surface of the steel wire. For example, a steel cord wire rod surface descaling abrasive belt machine proposed in CN217097095U uses the friction between the abrasive belt and the surface of the steel wire to remove the oxide scale. However, this method is only suitable for steel wire products with low surface requirements, and cannot meet the needs of some products with high surface requirements. Summary of the Invention

[0004] To address the technical problems existing in current steel wire grinding equipment, this utility model proposes a steel wire surface grinding device, comprising:

[0005] A support frame, with a first guide wheel assembly and a second guide wheel assembly located above the support frame;

[0006] The grinding cylinder is connected to the support frame and is located between the first guide wheel group and the second guide wheel group. The steel wire to be ground passes through the first guide wheel group, the grinding cylinder and the second guide wheel group in sequence.

[0008] A discharge device is connected to the grinding cylinder and is used to discharge the abrasive material inside the grinding cylinder;

[0009] The drive component is connected to the support frame;

[0010] The grinding cylinder is equipped with a stirring component, and the driving component is used to drive the stirring component to rotate at a predetermined speed, so that the abrasive material in the grinding cylinder comes into contact with the steel wire passing through the grinding cylinder, and the surface of the steel wire is ground.

[0011] Preferably, the grinding cylinder includes a cylindrical body with caps at both ends. The stirring component includes a stirrer and a shaft connected to the stirrer. The stirrer is located inside the cylindrical body, and the shaft extends from the inside of the cap through the cap to the outside of the cap. One end of the shaft is provided with a drive wheel, and the driving component is connected to the drive wheel.

[0012] Preferably, the inner side of the shaft is a hollow structure, forming a channel for the steel wire to pass through. The inner wall of the shaft is provided with a wire guide, through which the steel wire enters / exits the shaft.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] This application utilizes a stirring component to actively drive the abrasive material within a sealed grinding cylinder, creating a dynamic grinding environment that allows the abrasive material to fully envelop the steel wire, achieving three-dimensional grinding.

[0025] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0026] Combination Figure 1 As shown, the first aspect of this utility model proposes a steel wire surface grinding device, including a support frame 10, a grinding cylinder 20, a feeding device 30, a discharging device 40, and a driving component.

[0027] like Figure 1 As shown, a first guide wheel assembly 12 and a second guide wheel assembly 13 are provided above the support frame 10. The grinding cylinder 20 is connected to the support frame 10 and is located between the first guide wheel assembly 12 and the second guide wheel assembly 13.

[0028] The steel wire 100 to be ground can pass through the first guide wheel group 12, the grinding cylinder 20 and the second guide wheel group 13 in sequence. The first guide wheel group 12 and the second guide wheel group 13 limit the steel wire 100, so that the steel wire can pass through the grinding cylinder 20 in a predetermined direction and be surface treated by the abrasive material in the grinding cylinder 20.

[0029] Furthermore, a cover 11 is provided above the support frame 10. The cover 11 is located on the outside of the grinding cylinder 20. The feeding device 30 is connected to the grinding cylinder 20 and is used to add grinding material into the grinding cylinder 20. The discharging device 40 is connected to the grinding cylinder 20 and is used to discharge the grinding material in the grinding cylinder 20.

[0030] Thus, by controlling the feeding device 30 and the discharging device 40, the amount of abrasive material in the grinding cylinder 20 can be changed, or different types of abrasive material can be replaced to meet different process requirements.

[0031] Furthermore, the drive component is connected to the support frame 10, and the grinding cylinder 20 is provided with a stirring component. The drive component is used to drive the stirring component to rotate at a predetermined speed, so that the abrasive material in the grinding cylinder 20 comes into contact with the steel wire 100 passing through the grinding cylinder 20, and the surface of the steel wire 100 is ground.

[0032] In an optional embodiment, a monitoring device is provided at the outlet end of the grinding cylinder 20 to monitor the grinding quality of the ground steel wire 100, and to change the rotation speed of the stirring component, the volume of the grinding material, etc. according to the grinding quality, so that the surface of the steel wire 100 meets the process requirements.

[0033] It should be understood that, depending on different process requirements, the grinding quality can be changed by replacing different types and proportions of abrasive materials (wood balls + grinding powder), the rotation speed of the stirring components, and the amount of abrasive material, in order to adapt to the different process requirements of different products.

[0034] Combination Figure 2 As shown, the grinding cylinder 20 includes a cylindrical body 21, with caps 22 at both ends of the body 21. The caps 22 are detachably connected to both ends of the body 21 via threaded connectors.

[0035] Thus, the entire grinding cylinder 20 is designed as a detachable and assembleable structure, which facilitates the maintenance and replacement of the internal stirring components.

[0036] Furthermore, the stirring component includes a stirrer 24 and a shaft 23 connected to the stirrer 24. The stirrer 24 is located inside the cylindrical body 21, and the shaft 23 extends from the inside of the cover 22 through the cover 22 to the outside of the cover 22. One end of the shaft 23 is provided with a drive wheel 27, and the driving component is connected to the drive wheel 27 for transmission.

[0037] Optionally, the transmission wheel 27 is a sprocket or a synchronous belt pulley, and the driving component is a motor. The transmission belt / chain at the output end of the motor is connected to the transmission wheel 27. The drive shaft 23 rotates at a predetermined speed, causing the agitator 24 to drive inside the cylindrical body 21, stirring the abrasive material until it comes into contact with the steel wire, thereby achieving abrasion on the surface of the steel wire 100.

[0038] Optionally, the agitator 24 is configured as a hollow auger shape. This provides a central channel for the steel wire 100 to flow through, and also provides a stable and uniform dynamic grinding environment during rotation.

[0039] Combination Figure 2 As shown, the inner side of the shaft portion 23 is a hollow structure, forming a channel for the steel wire 100 to pass through. The inner wall of the shaft portion 23 is provided with a wire guide 28, through which the steel wire 100 passes into / out of the shaft portion 23.

[0040] Optionally, the wire guide 28 is made of carbide to prevent the steel wire from causing wear.

[0041] Combination Figure 3 and Figure 4 As shown, both the first guide wheel group 12 and the second guide wheel group 13 include a first guide wheel 122 and a second guide wheel 123.

[0042] Specifically, the first guide wheel group 12 and the second guide wheel group 13 each include a support plate 121. The first wire guide wheel 122 and the second wire guide wheel 123 are both connected to the support plate and are arranged in an alternating manner. A wire guide channel 124 is formed between the first wire guide wheel 122 and the second wire guide wheel 123. The axis of the wire guide nozzle 28 is collinear with the extension direction of the wire guide channel 124.

[0043] like Figure 2 As shown, a sealing structure is provided between the shaft portion 23 and the cylinder cover 22. Optionally, the sealing structure includes a sealing ring, a bearing 25, and a gland 26 arranged from the inside out. The bearing 25 is disposed between the inner wall of the cylinder cover 22 and the outer wall of the shaft portion 23. In this way, through the cooperation of the bearing and the seal, the shaft portion 23 and the cylinder cover 22 can rotate relative to each other, while preventing the overflow of grinding powder.

[0044] In conjunction with the above embodiments, this application utilizes a stirring component to actively drive the abrasive material within a sealed grinding cylinder to create a dynamic grinding environment. This allows the abrasive material to completely envelop the steel wire, achieving three-dimensional grinding. Compared to the single-point linear friction of traditional belt sanders, this application can efficiently remove oxide scale, micro-burrs, and contaminants, making it particularly suitable for high-end steel cord products with extremely high requirements for surface finish and consistency. Furthermore, by adjusting the stirring speed, abrasive type, and capacity, it can flexibly adapt to different steel wire diameters, strength grades, and surface treatment requirements, overcoming the limitation of traditional belt sanders being only suitable for low-standard products.

[0045] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
