Description

Technical Field

[0001] The utility model relates to the technical field of roller production, in particular to a cooling device for a roller. Background Art

[0002] For hot rolling, since the temperature of the rolled strip is relatively high (generally around 1000°C), corresponding requirements are put forward for the temperature control of the rolls. Generally, the instantaneous temperature of the rolls (i.e., working rolls) may reach 700-800°C during the rolling process. After a certain period of water cooling (the gap between the rolled strips), the temperature is roughly controlled at around 80°C. In special cases, the temperature of the rolls may reach around 100°C.

[0003] The traditional method of cooling the rolled tube is to spray the coolant directly onto the rollers. During the cooling process, the coolant will splash when it touches the rollers, which is unsafe. The generated mist will spread and affect the surrounding working environment. Utility Model Content

The gear 1 is installed at one end of the load-bearing roller, and the gears 1 on the two groups of the load-bearing rollers are connected through a synchronous belt transmission.

[0007] By adopting the above technical solution, when spraying coolant on the roller, the rebound and splashing of the coolant can be effectively reduced, and when the coolant contacts the roller, more mist will be generated, which can be sucked by the fan to reduce the impact of the mist on the working environment.

[0008] The displacement mechanism includes a second motor and a lead screw. The second motor has two motors respectively distributed on both sides of the base, and the lead screw is installed at the output end of the second motor.

[0009] By adopting the above technical solution, the bracket is moved to facilitate the placement of the roller.

[0010] The interior of the base is a hollow structure, and two sides thereof are provided with sliding grooves for accommodating the lead screws, and the bottom of the bracket slides in the sliding grooves.

[0011] By adopting the above technical solution, the base can collect the coolant after the temperature reduction treatment.

[0012] There are four groups of wire drums on the coupling shaft, wherein the traction wires on two groups of wire drums are wound out from the upper side of the wire drums to one side, and the traction wires on the other two groups of wire drums are wound out from the lower side of the wire drums to the other side.

[0013] By adopting the above technical solution, the motor three can be controlled to raise and lower the two sets of guard plates at the same time.

[0014] Transparent acrylic plates are provided in the middle of both sides of the bracket.

[0016] The beneficial effects of the cooling device for the roller of the utility model are:

[0017] 1. Drive motor 2 is set to drive the bracket to move through the lead screw, so that the bracket moves from the top of the load-bearing roller to one side, and then the roller is placed on the load-bearing roller, and then the motor 2 is driven to move the bracket to the top of the load-bearing roller. At this time, the drive motor 3 drives the wire drum to rotate through the connecting shaft, releases the traction wire wound around it, and slowly lowers the guard plate. The guard plate can be set up to install the spray pipe on the guard plate to prevent the coolant from splashing during the process of coolant spraying and cooling;

[0018] 2. When the coolant contacts the roller, more mist will be generated. The effect of the mist on the working environment can be reduced by suction through the fan. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0023] Reference Figure 1-2 A cooling device for a rolling mill roll comprises a base 1 and a displacement mechanism installed on the base 1, a driving mechanism and a cooling mechanism installed on the moving mechanism, the cooling mechanism comprises a spray pipe 5, a bracket 7, a motor 3 10, a coupling 11, a wire drum 12, a traction wire 13, a guard plate 14, a fan 15 and an air suction hood 16, the motor 3 10 is installed on the bracket 7, the wire drum 12 is fixedly mounted at the output end of the motor 3 10 through the coupling 11, the guard plate 14 is hingedly arranged on both sides of the bracket 7, one end of the traction wire 13 is wound around the wire drum 12, and the other end is connected to the guard plate 14, the spray pipe 5 is distributed at the bottom of the bracket 7 and the inner side of the guard plate 14, the bracket 7 is also equipped with a fan 15, and the bottom of the fan 15 is equipped with an air suction hood 16;

[0024] The driving mechanism includes a motor 2, a bearing roller 3, a gear 4 and a synchronous belt 6. The bearing rollers 3 are two groups rotatably installed in the base 1, and one group of the bearing rollers 3 is fixedly connected to the output end of the motor 2. The gear 4 is installed at one end of the bearing roller 3. The gears 4 on the two groups of bearing rollers 3 are connected through the synchronous belt 6.

[0025] The second driving motor 8 drives the bracket 7 to move through the lead screw 9, so that the bracket 7 moves from the top of the bearing roller 3 to one side, and then the roller is placed on the bearing roller 3, and the second driving motor 8 is driven again to move the bracket 7 to the top of the bearing roller 3. At this time, the third driving motor 10 drives the wire drum 12 to rotate through the connecting shaft 11, releases the traction wire 13 wound around it, and slowly puts down the guard plate 14. (It should be noted that a counterweight block is provided at the bottom of the guard plate 14 to prevent the guard plate 14 from being unstable when the spray pipe 5 cools the roller). After that, it can drive a corresponding group of bearing rollers 3 to rotate. While the group of bearing rollers 3 rotates, the other group of bearing rollers 3 is driven to rotate through 6, so that the two groups of bearing rollers 3 drive the rollers to rotate, and connect the external water pump to transport the coolant to the spray pipe 5 for spraying, so as to cool the rollers during the rotation process;

[0026] The provision of the guard plate 14 allows the spray pipe 5 to be mounted on the guard plate 14, thereby preventing the coolant from splashing during the process of the coolant being sprayed out and cooled.

[0027] The displacement mechanism includes a motor 8 and a screw 9. The motor 8 is composed of two motors distributed on both sides of the base 1, and the screw 9 is installed at the output end of the motor 8. After the motor 8 is driven to move the screw 9 to the top of the load-bearing roller 3, the guard plate 14 is lowered. When the roller is sprayed with coolant subsequently, the bracket 7 and the guard plate 14 can block the splashing of the spraying liquid to a certain extent. When placing and removing the roller, the motor 8 is driven to drive the bracket 7 to move to one side of the load-bearing roller 3 through the screw 9. At this time, the bracket 7 is not directly above the load-bearing roller 3, which is convenient for the subsequent placement of the roller on the two groups of load-bearing rollers 3.

[0028] The interior of the base 1 is a hollow structure, and slide grooves for placing the lead screw 9 are opened on both sides of the base 1, and the bottom of the bracket 7 slides in the slide grooves; transparent acrylic plates are set in the middle of both sides of the bracket 7 to facilitate moving the bracket 7 to a predetermined position, and the acrylic plates on both sides of the bracket 7 can prevent the coolant from splashing and facilitate observation of the cooling condition.

[0029] There are four groups of wire drums 12 on the connecting shaft 11, among which the traction lines 13 on two groups of wire drums 12 are wound out from the upper side of the wire drums 12, and the traction lines 13 on the other two groups of wire drums 12 are wound out from the lower side of the wire drums 12. According to this arrangement, when the motor three 10 is driven, the connecting shaft 11 is driven to rotate, and the guard plates 14 on both sides of the bracket 7 can be synchronously driven to rise and fall through the traction lines 13.

[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
