Description

Technical Field

[0001] This invention relates to a centralized pretreatment line for wire rods and its production and application method, belonging to the field of steel cord production technology. Background Technology

[0002] The processing of wire products such as steel cord cannot be separated from the required raw materials (wire rod). The surface of the wire rod is covered with a layer of oxide scale. During the processing on the production line, the surface of the wire rod needs to be pre-treated to remove the oxide scale and cover it with a layer of borax coating.

[0003] There are various methods for surface pretreatment of wire rods on production lines, such as chemical pickling after mechanical stripping, electrolytic pickling, wire brushing, belt sanding, ultrasonic treatment, and shot peening. Existing production lines use single-strand single-control or multi-strand centralized processing methods. However, due to factors such as environmental protection and differences among wire rod manufacturers, issues such as variations in the oxide scale and surface corrosion caused by protective measures exist. Therefore, it is necessary to invent a centralized wire rod pretreatment line and its production and usage method to facilitate rapid centralized pretreatment of wire rods, improve production line efficiency, and achieve energy conservation and environmental protection goals. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a centralized wire pretreatment line and its production and use method, which can effectively solve the existing wire rod surface pretreatment problem. The device is safe, reliable, and easy to operate; it can reduce production costs and improve production efficiency.

[0005] To achieve the above objectives, the present invention is implemented using the following technical solution: In a first aspect, the present invention provides a centralized pre-processing line for wires, comprising: A wire rod feeder is installed at the beginning of the production line to guide the wire rod feeder. The tangled wire protection device is installed after the wire feeding rack and is used to trigger a stop when tangled wires appear in the wire to prevent the wire from running out of the coil. The mechanical stripping wheel assembly is installed after the tangled wire protection device. It uses two sets of guide wheels to bend and deform the wire to remove the surface oxide scale. Surface treatment equipment, including a wire brush machine or a belt sander, is installed after the mechanical stripping wheel assembly and is used to treat the surface of the wire rod according to production needs; A cleaning and coating device, located after the surface treatment device, is used to clean and coat wire rods. An oven, located after the cleaning and coating equipment, is used to dry the surface-treated wire rods. The wire rod defect detector is installed between the drying oven and the wire drawing machine to detect wire rod defects online and trigger alarms or shutdown procedures. A wire drawing machine, located at the end of the production line, is used to draw qualified wire rods into the desired products.

[0006] Furthermore, a centralized wire guide wheel group, a centralized wire pressing wheel group, and a wire separator are sequentially arranged between the surface treatment device and the cleaning and coating device. The centralized wire guide wheel group and the centralized wire pressing wheel group are used to independently guide and stabilize the wire routing position of each wire rod. The wire separator has several small holes to guide the wire rods to pass through sequentially.

[0007] Furthermore, the cleaning and coating device includes a high-pressure water rinsing tank, a segmented pickling tank, a centralized cold water rinsing tank, a centralized hot water rinsing tank, and a centralized boron coating tank. The high-pressure water rinsing tank is installed after the dividing plate and is used to rinse the surface of the wire rod with high-pressure water. The segmented pickling tank is installed after the high-pressure water rinsing tank. The centralized cold water rinsing tank is installed after the segmented pickling tank and is used to rinse the surface of the wire rod with water. The centralized hot water rinsing tank is installed after the centralized cold water rinsing tank and is used to rinse the surface of the wire rod with hot water. The centralized boron coating tank is installed after the centralized hot water rinsing tank and is used to coat the surface of the wire rod.

[0008] Furthermore, the segmented pickling tank is designed with a structure in which half of it contains solution, half does not contain solution, or the entire tank can contain solution.

[0009] Furthermore, the dividing board has a 10mm hole made of cemented carbide material.

[0010] Furthermore, when producing different wire rods, depending on the material and thickness of the oxide scale, one may choose to use a wire brush machine or a belt sander, or perform pickling or a combination of both.

[0011] Secondly, the present invention provides a method for production and use of a wire centralized pretreatment line according to any one of the foregoing claims, comprising: Configure the number of machine tools and wire rod feeding frame groups on the production line according to production needs; The wire rod is installed on the wire rod pay-off stand and passes through the wire tangling protection device, mechanical stripping wheel set, surface treatment device, centralized wire passing wheel set, centralized wire pressing wheel set, wire separating plate, cleaning and coating device, drying oven and wire rod defect detector in sequence, and finally enters the wire drawing machine for drawing; Depending on the material and thickness of the oxide scale on the wire rod, the surface of the wire rod may be treated by using a wire brush or belt sander, pickling, or a combination of both. Monitor the test results of the wire rod defect detector and trigger alarms or shutdown procedures as needed.

[0012] Furthermore, each machine tool can be started and operated independently, run at different speeds, or remain stationary.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. This invention provides a centralized pretreatment line for wire rods and its production and usage method. By integrating multiple processing equipment, such as mechanical stripping wheel sets, wire brush machines / sand belt machines, segmented pickling tanks, centralized cleaning tanks, and coating tanks, it realizes continuous and automated production of wire rods from unwinding to pretreatment and then to drawing. This invention has a simple structure and is easy to operate. It improves the surface treatment quality of existing wire rods, increases production efficiency, promotes green and low-carbon operation, and reduces production costs. 2. This invention utilizes a variety of processing methods, such as mechanical peeling wheel sets, wire brush machines / sand belt machines, and segmented pickling tanks, to precisely process the oxide scale of different wire rods. This targeted processing solution can more effectively remove the oxide scale and other impurities from the surface of the wire rods, providing higher quality raw materials for subsequent drawing, rolling, and other processing processes, thereby improving the quality of the final product.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] Example 1, as Figure 1 As shown in the figure, this embodiment introduces a centralized wire pretreatment line, which mainly consists of a wire feeding rack 1, a tangled wire protection device 2, a mechanical stripping wheel set 3, a surface treatment device 4, a centralized wire passing wheel set 5, a centralized wire pressing wheel set 6, a wire separating plate 7, a cleaning and coating device, an oven 13, a wire defect detector 14, and a wire drawing machine 15. The surface treatment device 4 includes a wire brush machine A or a belt sander B. The cleaning and coating device includes a high-pressure water rinsing tank 8, a segmented pickling tank 9, a centralized cold water washing tank 10, a centralized hot water washing tank 11, and a centralized boron coating tank 12.

[0020] The wire rod pay-off frame 1 is installed on the far left of the centralized pre-processing line. The duckbill type pay-off frame facilitates wire rod guide and pay-off.

[0021] The aforementioned tangled wire protection device 2 is installed after the wire feeding rack 1 and is used to trigger a stop to prevent the wire from running out of control when tangled wires appear on the wire.

[0022] The mechanical stripping wheel set 3 is installed behind the wire rod pay-off frame. The mechanical stripping wheel set 3 consists of two sets of guide wheels, one upper and one lower. The wire rod passes through the middle and is bent and deformed to remove the oxide scale from the surface.

[0023] The wire brush machine A or belt sander B is installed after the mechanical peeling wheel assembly 3 and can be selected for use according to production needs.

[0024] The centralized guide roller group 5 is installed after the wire brush machine A / belt sander B, and each wire rod independently passes through the corresponding guide roller on the centralized guide roller group 5.

[0025] The centralized pressing wheel group 6 is installed after the centralized passing wheel group 5, and each wire rod passes independently through the corresponding pressing wheel on the centralized pressing wheel group 5.

[0026] The wire divider 7 is installed after the centralized wire pressing wheel group 6. The wire divider has a 10mm hole and is made of hard alloy material to facilitate the wire rod to pass through the wire divider in sequence.

[0027] The centralized wire guide wheel group 5, centralized wire pressing wheel group 6, and wire separating plate 7 are not limited to being installed in the above-mentioned positions. They can be installed at other inlet and outlet positions of the trough to stabilize the wire routing position of the wire rod.

[0028] The high-pressure water rinsing tank 8 is installed behind the dividing plate 7 to perform high-pressure water rinsing on the surface of the wire rod.

[0029] The segmented pickling tank 9 is installed after the high-pressure water rinsing tank 8. The tank is designed in segments, with one half containing solution and the other half without solution, or the entire pickling tank can contain solution.

[0030] The centralized cold water washing tank 10 is installed after the segmented pickling tank 8 to rinse the surface of the wire rod with water.

[0031] The centralized hot water washing tank 11 is installed after the centralized cold water washing tank 10 to wash the surface of the wire rod with hot water.

[0032] The centralized boron coating tank 12 is installed after the centralized hot water washing tank 11 to coat the surface of the wire rod, which facilitates the subsequent wire drawing.

[0033] The oven 13 is installed after the centralized boron coating tank 12 to dry the surface-treated wire rods.

[0034] The wire rod defect detector 14 is installed between the drying oven 13 and the wire drawing machine 15. It is used to detect defects in wire rods. If an abnormality occurs, it will trigger an online alarm or stop the machine, which will facilitate the identification and differentiation of abnormal wire rods.

[0035] The wire feeding frame 1 and the wire drawing machine 15 can be installed perpendicular to each trough, parallel to each trough, or at other angles depending on the site conditions, which can effectively utilize the site space and reduce the area occupied by the equipment.

[0036] Example 2: This example provides a production method for a wire centralized pretreatment line according to any one of Examples 1, comprising: The specific number of machine tools on the production line should be configured according to production capacity requirements, and the number of wire feeding frame sets (two per set for convenient continuous wire feeding) should correspond to the number of machine tools. The wire feeding frames and machine tools can be installed perpendicular to, parallel to, or at other angles to the site conditions. During installation, appropriate guide wheels should be added to guide the wire.

[0037] When using the wire rod centralized pre-treatment production line of the present invention, the corresponding wire rods are loaded on the wire feeding frame, and then the wire rods are passed sequentially through the tangled wire protection device, the mechanical stripping wheel group, the wire brush machine A or the belt sander B (optional installation), and together with the wire rods passing through the other wire feeding frames, they pass through the corresponding guide wheels on the centralized wire passing wheel group and the centralized wire pressing wheel group. The guide wheels can rotate flexibly and independently. After all the wire rods pass through the wire separating plate, they enter the high-pressure water washing tank, the segmented pickling tank, the cold water washing tank, the hot water washing tank, the boron coating tank, the drying oven, and the wire rod defect detector in sequence before entering the wire drawing machine to be drawn into the required product.

[0038] A centralized wire pretreatment line allows each machine tool to be started and operated independently, run at different speeds, or remain stationary.

[0039] When producing different types of wire rods, depending on the material and thickness of the oxide scale, after mechanical peeling, one of the following three methods can be used to further treat the residual oxide scale on the wire surface: 1. Wire brush machine A or belt sander B; 2. Pickling; 3. Wire brush machine A or belt sander B plus pickling. If method 1 is used, the wire rod needs to be separated from the pickling solution in the acid tank. If the oxide scale on the wire rod surface is thin and the material is easy to remove, only simple mechanical treatment is needed. Brushing or grinding with a wire brush machine or belt sander can achieve the desired cleaning effect. If the oxide scale is thick or the material is difficult to remove, simple mechanical treatment is not enough to completely remove it. In this case, pickling or a combination of mechanical treatment and pickling is required.

[0040] By adopting the above technical solution, the surface of wire rod can be pre-treated in a centralized manner, which can effectively reduce the equipment footprint. At the same time, the centralized wire pre-treatment line is more energy-efficient and environmentally friendly, and improves the production efficiency of the line.

[0041] The device of this invention has a simple structure, is safe and reliable, and is very convenient to operate, use and maintain.

[0042] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
