Description

Technical Field

[0001] The utility model relates to the technical field of wire rolling mills, in particular to a roll cooling device for a fine wire rolling mill and a fine wire rolling mill. Background Technique

[0002] A rolling mill mainly consists of a roll, a frame, a roll gap adjusting device, a roll temperature adjusting device, a transmission device, a lubrication system, a control system, a roll removing device, etc. These parts cooperate together to complete the rolling process of metal materials. According to the design and application requirements of the rolling mill, the number and arrangement of rolls are different. Common fine wire rolling mills may adopt a multi-roll design, such as three rolls, four rolls, etc., to ensure precise control and processing of metal materials.

[0003] During the fine wire rolling process, the rotational speed of the roll is relatively high, which will generate a large amount of heat, and then make the surface of the roll hotter. If the working roll is not sufficiently cooled, the roll ring is prone to "roll explosion", thereby reducing the quality of the fine wire finished product.

[0004] Therefore, a roll cooling device for a fine wire rolling mill and a fine wire rolling mill are proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a roll cooling device for a fine wire rolling mill and a fine wire rolling mill to solve the problems raised in the above background technique.

[0034] A limiting mechanism 2 is provided above the processing table 1 for limiting the thin wire. The limiting mechanism 2 includes mounting plates 201 fixedly installed on the left and right sides of the two support frames 103. Three L-shaped plates 202 are fixedly installed on the sides of the two mounting plates 201 away from each other. Fixed sleeves 203 are fixedly installed on the top surfaces of the three L-shaped plates 202. A plurality of first rotating shafts 204 and a plurality of second rotating shafts 205 are fixedly installed on the top surfaces of the mounting plates 201.

Two limiting sleeves 208 are fixedly installed on the top surface of the fixed frame 102;

[0035] By providing the fixed sleeves 203, the thin wire can be initially limited. Through the settings of the first rotating shaft 204, the second rotating shaft 205, the first limiting wheel 206, the second limiting wheel 207 and the limiting sleeve 208, the thin wire can be limited when entering and exiting the machine, ensuring that the thin wire is in the processing position without deviation and ensuring the processing quality of the thin wire;

[0036] Embodiment 2: As Figures 1-4As shown in the figure, a roll cooling device for a thin wire rolling mill disclosed in the second embodiment of the present utility model has basically the same structure as that in the first embodiment. The difference lies in the roll mechanism 3, which is arranged in the middle of the limit mechanism 2 and is used for rolling thin wires. The roll mechanism 3 includes a mounting frame 301 fixedly installed on the front side of the processing table 1. A motor 302 is fixedly installed on the rear side of the mounting frame 301. A first connecting shaft 304 is fixedly installed at the output end of the motor 302. A through groove 303 is formed through the top surface of the processing table 1. The rear end of the first connecting shaft 304 rotatably penetrates the front side of the fixed frame 102 and is rotatably connected to the inner wall of the rear end of the fixed frame 102. A first roll 305 is fixedly sleeved on the outer wall of the first connecting shaft 304. A first gear 306 is fixedly installed on the outer wall of the front end of the first connecting shaft 304. A second gear 307 is meshed with the outer wall of the first gear 306. A second connecting shaft 308 is fixedly installed inside the second gear 307. The rear end of the second connecting shaft 308 rotatably penetrates the front side of the front support frame 103 and is rotatably connected to the front side of the rear support frame 103. A second roll 309 is fixedly sleeved on the outer wall of the second connecting shaft 308;

[0037] By starting the motor 302, the first connecting shaft 304, the first roll 305 and the first gear 306 are driven to rotate. The first gear 306 drives the second gear 307 and the second connecting shaft 308 to rotate. The second connecting shaft 308 drives the second roll 309 to rotate. Under the combined action of the first roll 305 and the second roll 309, multiple thin wires are simultaneously rolled, and the efficiency is relatively high;

[0038] Embodiment 3: As Figures 1-4 shown, a roll cooling device for a thin wire rolling mill disclosed in the third embodiment of the present utility model has basically the same structure as that in the second embodiment. The difference lies in the cooling mechanism 4, which is arranged above the roll mechanism 3 and is used for cooling the roll mechanism 3. The cooling mechanism 4 includes a fixing plate 401 fixedly installed on the rear side of the rear support plate 101. A water tank 402 is fixedly installed on the top surface of the fixing plate 401. A water pump 403 is fixedly installed on the top surface of the water tank 402. The water pump 403 is connected to the top surface of the water tank 402 through a connecting pipe 404 in a penetrating manner. A spray pipe 405 is fixedly installed at the water outlet of the water pump 403. A plurality of nozzles 406 are installed through the outer wall of the spray pipe 405.

[0039] By starting the water pump 403, the water pump 403 sucks the coolant from the water tank 402 through the connecting pipe 404. The water pump 403 sprays the coolant from the nozzles 406 through the spray pipe 405. The coolant is sprayed onto the rolls, so that the rolls are cooled and will not overheat during operation, resulting in a decline in the quality of the thin wire finished products.

[0040] A fine wire rolling mill includes a cooling device for the rolls of the fine wire rolling mill.

[0041] Specifically, the fine wire is passed through the fixed sleeve 203, the first limiting wheel 206, the second limiting wheel 207 and the limiting sleeve 208, which can limit the fine wire when it enters and exits the machine, ensure that the fine wire is in the processing position, prevent deviation, and ensure the processing quality of the fine wire. The motor 302 is started to drive the first connecting shaft 304, the first roll 305 and the first gear 306 to rotate. The first gear 306 drives the second gear 307 and the second connecting shaft 308 to rotate. The second connecting shaft 308 drives the second roll 309 to rotate. Under the combined action of the first roll 305 and the second roll 309, multiple fine wires are simultaneously rolled, with relatively high efficiency. At the same time, the water pump 403 is started. The water pump 403 sucks the coolant from the water tank 402 through the connecting pipe 404, and the water pump 403 sprays the coolant from the nozzle 406 through the water spraying pipe 405. The coolant is sprayed onto the rolls, so that the rolls are cooled and will not overheat during operation, resulting in a decline in the quality of the fine wire finished products.
