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

[0003] There are many ways to pre-treat the surface of wire rods in production lines, such as chemical pickling, electrolytic pickling, wire brush, sanding machine, ultrasonic, shot peening, etc. after mechanical shelling of wire rods. Existing production lines have single-wire single-control or multi-wire centralized processing methods. With the green environmental protection and other factors, including different wire rod manufacturers, the differences in wire rod oxide scales and surface rust caused by protection exist. Therefore, it is necessary to invent a centralized wire pre-treatment line and its production and use method, so as to facilitate and quickly pre-treat the wire rods, improve the production line operation efficiency, and achieve energy conservation and environmental protection.

[0019] Embodiment 1, as Figure 1 As shown, this embodiment introduces a centralized wire pretreatment operation line, which is mainly composed of a wire rod pay-off rack 1, a tangled wire protection device 2, a mechanical shelling wheel group 3, a surface treatment device 4, a centralized wire passing wheel group 5, a centralized wire pressing wheel group 6, a wire dividing plate 7, a cleaning and coating device, an oven 13, a wire rod defect detector 14 and a wire drawing machine 15. The surface treatment device 4 includes a wire brush machine A or a sanding machine B, and the cleaning and coating device includes a high-pressure water washing 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 stand 1 is installed on the leftmost side of the centralized pre-processing operation line, and the duckbill type pay-off stand is convenient for guiding and releasing the wire rod.

[0021] The tangled wire protection device 2 is installed behind the wire rod pay-off frame 1, and is used to trigger the stop when tangled wires appear on the wire rod to prevent the wire rod from running away.

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

[0023] The wire brush machine A or the sand belt machine B is installed behind the mechanical shelling wheel group 3 and can be selected and used according to production needs.

[0024] The centralized wire-passing wheel set 5 is installed behind the wire brush machine A / sand belt machine B, and each wire rod passes through the corresponding wire-passing wheel on the centralized wire-passing wheel set 5 independently.

[0025] The centralized crimping wheel set 6 is installed behind the centralized wire passing wheel set 5, and each wire rod passes independently through the corresponding crimping wheel on the centralized crimping wheel set 5.

[0026] The line dividing plate 7 is installed behind the centralized line pressing wheel set 6. The line dividing plate has a 10 mm hole and is made of hard alloy material to facilitate the wire rods to pass through the line dividing plate in sequence.

[0027] The centralized wire-passing wheel set 5, centralized wire-pressing wheel set 6, and wire-dividing plate 7 are not limited to being installed at the above-mentioned positions, but may be selectively installed at other slot inlet and outlet positions to stabilize the wire rod routing position.

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

[0029] The segmented pickling tank 9 is installed after the high-pressure water washing tank 8. The tank body is designed in segments, with half of it having solution and half without solution, or the entire pickling tank can have solution.

[0030] The centralized cold water washing tank 10 is installed after the segmented pickling tank 8 to wash 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 perform coating treatment on the surface of the wire rod to facilitate subsequent wire drawing.

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

[0034] The wire rod defect detector 14 is installed between the oven 13 and the wire drawing machine 15, and is used to perform flaw detection on the wire rod. If an abnormality occurs, an online alarm will be issued or the machine will be stopped, so as to facilitate the identification and distinction of abnormal wire rods.

[0035] The wire rod pay-off frame 1 and the wire drawing machine 15 can be installed perpendicular to each trough body, parallel to each trough body or at other angles according to the site, which can effectively utilize the site and reduce the area occupied by the equipment.

[0036] Embodiment 2: This embodiment provides a production and use method of a wire centralized pretreatment line according to any one of Embodiment 1, comprising: The number of machine tools for the specific operation line is configured according to the production capacity requirements, and the number of pay-off racks (two in a group, convenient for continuous feeding of wire rods) corresponds to the number of machine tools. When designing the installation, the wire rod pay-off rack and machine tools can be installed perpendicular to each trough, parallel to each trough or at other angles based on the site. During installation, corresponding wire wheels need to be added to guide the wire rods.

[0037] When using the centralized wire pretreatment operation line of the present invention for production, the corresponding wire rods are placed on the pay-off stand, and then the wire rods are sequentially passed through a tangled wire protection device, a mechanical shelling wheel group, a wire brush machine A or a sanding machine B (optional installation), and together with the wire rods passed through other pay-off stands, they are passed 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 independently. After passing through the wire dividing plate, all the wire rods sequentially 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, the wire rod defect detector, and then enter the wire drawing machine to be drawn into the required products.

[0038] Each machine tool in a centralized wire pre-processing line can be started and operated independently, operated at different speeds, or kept in a stopped state.

[0039] When producing different wire rods, according to the material and thickness of the wire rod oxide scale, one of the following three schemes can be used to further treat the residual oxide scale on the surface of the steel wire after mechanical peeling: 1. Wire brush machine A or sanding machine B treatment; 2. Pickling treatment; 3. Wire brush machine A or sanding machine B treatment plus pickling treatment; If scheme 1 is used, the wire rod needs to be separated from the pickling liquid in the acid tank; if the oxide scale on the surface of the wire rod is thin and the material is easy to remove, only simple mechanical treatment is required, such as brushing or grinding with a wire brush or sanding machine to achieve the ideal cleaning effect; if the oxide scale is thick or the material is difficult to remove, simple mechanical treatment is difficult to completely remove it, and pickling treatment or a combination of mechanical treatment and pickling treatment is required.

[0040] After adopting the above technical solution, the surface of the wire rod can be centrally pretreated, effectively reducing the equipment footprint. At the same time, the centralized wire pretreatment operation line is energy-saving and environmentally friendly, and improves the production efficiency of the operation line.

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

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
