The wide cold rolling work roll heat treatment quenching equipment provides a stable support foundation through the mounting plate 1, and the combination of the heating mechanism 205, the fixed plate 207 and the heating ring 208 realizes precise heating of the roller body 4. At the same time, the plurality of water spraying nozzles 209 below the fixed plate 207 and the separating mechanism 3 on the outside not only ensure uniform cooling during the quenching process, but also effectively collect the cooling liquid, reducing waste and environmental pollution. This structure design makes the equipment compact and functional, improves the quenching efficiency and quality.

[0030] Referring to Figure 1 , Figure 3 , Figure 4 , the separation ring 302 is sleeved on the outside of the roller body 4, and a gap is formed between the inside of the separation ring 302 and the outer wall of the roller body 4. The separation ring 302 is sleeved on the outside of the roller body 4 and forms a gap with the roller body. The gap is to remove the surface roller body 4 and the separation ring 302, to improve the smoothness of the roller body 4 during rotation, to ensure the stability and uniformity of the quenching process, and to guide the cooling liquid between the receiving frame 301 and the separation ring 302, and then discharge from 303, so as to realize the smooth collection of the cooling liquid, avoid the contact between the cooling liquid and the roller body 4, and thus realize the beneficial effect of avoiding the splashing of the cooling liquid.

[0031] Referring to Figure 1 , Figure 3 , Figure 4 , a plurality of water nozzles 209 are arranged in an equidistant ring along the central axis of the heating ring 208, and the water nozzles 209 are connected to the external cooling liquid storage device through the liquid pump. The plurality of water nozzles 209 are arranged in an equidistant ring along the central axis of the heating ring 208. This layout ensures that the cooling liquid can be uniformly and comprehensively sprayed onto the surface of the roller body 4, improving the uniformity and consistency of the quenching effect. At the same time, the water nozzles 209 are connected to the external cooling liquid storage device through the liquid pump, realizing the recycling and automatic replenishment of the cooling liquid, reducing the operation complexity and improving the production efficiency.

[0032] Referring to Figure 1 , Figure 2 , the surface of the mounting plate 1 is mounted with a first linear motor 201 and a second linear motor 202, the first linear motor 201 is mounted with a movable plate 203, and the second linear motor 202 is mounted with a support plate 204. The first linear motor 201 and the second linear motor 202 mounted on the surface of the mounting plate 1 drive the movement of the movable plate 203 and the support plate 204 respectively. This dual-motor driven design allows the device to flexibly adjust the position and posture of the roller body 4 during quenching, adapting to the processing needs of roller bodies of different sizes and shapes. At the same time, the automatic operation of the motor drive also improves the production efficiency and accuracy of the device.

[0033] Referring to Figure 1 , Figure 2 , the front side of the movable plate 203 is mounted with an upper limit pressure piece 5, and the lower side of the quenching device is provided with a driving mechanism 6. The driving mechanism 6 includes a motor and a speed reducer, and the output part is mounted with a lower limit pressure piece 7. The upper limit pressure piece 5 and the lower limit pressure piece 7 limit the upper and lower ends of the roller body 4. The upper limit pressure piece 5 mounted on the front side of the movable plate 203 and the lower limit pressure piece 7 driven by the motor and speed reducer of the driving mechanism 6 below the quenching device jointly limit the upper and lower ends of the roller body 4. This double-limiting design ensures the stability and safety of the roller body during quenching. At the same time, the combination of the motor and the speed reducer of the driving mechanism 6 provides strong power support, so that the roller body can rotate smoothly, further improving the quenching effect and quality.

[0034] Referring to Figure 1 , Figure 2The support plate 204 is slidably installed on the heating mechanism 205 through the adjusting hand wheel 206, and the screw rod at the end of the adjusting hand wheel 206 is threadedly connected with the heating mechanism 205. The adjustable design makes the position of the heating mechanism 205 flexible according to actual needs. This design not only improves the versatility and adaptability of the equipment, but also facilitates the maintenance and maintenance of the equipment, and reduces the use cost.

[0035] Referring to Figure 1 、 Figure 2 The quenching equipment is provided with a water receiving frame 8 below the outer side, and the water receiving frame 8 is communicated with the waste water storage device outside. The water receiving frame 8 provided below the outer side of the quenching equipment is communicated with the waste water storage device outside. This design effectively collects the splashing and flowing cooling liquid in the quenching process, avoids the pollution of the cooling liquid to the equipment and the environment. At the same time, the recycling and utilization of waste water reduce the production cost and improve the utilization rate of resources. The setting of the water receiving frame 8 also makes the equipment more clean and beautiful, improves the overall quality and use experience of the equipment.

[0036] In the implementation, first, the roller body 4 is placed on the output part of the driving mechanism 6, that is, the lower limit pressure piece 7, the first linear motor 201 is started, the movable plate 203 is moved forward, the upper limit pressure piece 5 is pressed downward, the roller body 4 is pressed and limited from the upper and lower ends by the lower limit pressure piece 7, and the heating mechanism 205 is started. The heating ring 208 starts to work and uniformly heats the roller body 4. During the heating process, the temperature and heating time of the heating ring 208 can be adjusted according to needs to ensure that the roller body 4 reaches the required quenching temperature.

[0037] When the roller body 4 reaches the quenching temperature, the liquid pump is started, and the cooling liquid is uniformly sprayed to the surface of the roller body 4 through the water spraying nozzle 209. The water spraying nozzle 209 is arranged in an equidistant ring shape along the central axis of the heating ring 208, so as to ensure that the cooling liquid can uniformly cover the surface of the roller body 4.

[0038] During use, the cooling liquid sprayed to the surface of the roller body 4 splashes under the action of centrifugal force. However, the separation ring 302 in the separation mechanism 3 is sleeved outside the roller body 4, effectively blocks the splashing of the cooling liquid, and limits the cooling liquid to the inside of the roller body 4 and the receiving frame 301, and flows down along the inner walls of the receiving frame 301 and the separation ring 302, and is discharged through the liquid outlet 303. The discharged cooling liquid is collected by the water receiving frame 8 and guided to the waste water storage device outside through the pipeline for recycling and treatment.

[0040] 1. By setting the receiving frame and the separation ring, the path of the cooling liquid splashing outward due to the centrifugal force after impacting the roller body surface is effectively blocked, so that the cooling liquid is limited in the gap between the receiving frame and the separation ring;

[0041] 2. The original form of the cooling liquid directly contacting the roller body is improved to the form of the cooling liquid being separated from the roller body by the separation mechanism, avoiding the influence of the roller body rotation on the cooling liquid;

[0042] 3. By effectively controlling the splashing of the cooling liquid, the cooling liquid is prevented from splashing into the external environment, thereby protecting the environment.
