Description

Technical Field

[0001] This utility model relates to the field of heat treatment spraying technology for rolling mill rolls, specifically a heat treatment spraying device for rolling mill rolls. Background Technology

[0002] Roll quenching is a heat treatment process used to improve the surface hardness and wear resistance of rolls. Its basic principle is to increase the surface hardness of the roll through rapid cooling while maintaining good internal toughness.

[0003] The existing Chinese patent announcement number CN221626337U, entitled "A Cold Roll Spray Quenching Equipment", describes in its abstract that "this utility model has a series of structures that facilitate the driving of the cold rolling roll to rotate, facilitate the spray quenching treatment of the rotating cold rolling roll, facilitate the driving of the shield to move down and close before spray quenching and automatically control and tighten it, and the shield can block the splashed and splattered quenching oil, prevent the quenching oil from splashing out in large quantities, improve the safety and cleanliness of use, and facilitate the centralized recovery of the quenching oil after spray quenching".

[0004] However, in this technology, the nozzle position is fixed and can only be adjusted up and down with the shielding cover. Furthermore, the device can only rotate the roller and cannot be adjusted in position. As a result, when quenching the roller, the nozzle can only quench one part of the roller, which cannot achieve a good quenching effect. In addition, since there are some metal or other impurities on the roller, when the quenching oil is collected and recycled, the impurities are also recycled along with it, resulting in poor recycling quality. Therefore, subsequent cleaning of the impurities is required, which is quite troublesome. Utility Model Content

[0005] The purpose of this invention is to provide a heat treatment spray quenching device for rolling mill rolls to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat treatment spray quenching device for rolling mill rolls includes a base and a placement frame. Support columns are arranged around the base, and a spray quenching frame is positioned on top of the support columns. Two rotating rollers are arranged inside the placement frame. A first motor is located on one side of the placement frame and connected to one of the rotating rollers. A connecting frame is located at the bottom of the placement frame. Electric push rods are arranged on both sides above the base and connected to the bottom sides of the connecting frame. An oil outlet groove is located inside the bottom of the connecting frame, and a filter assembly is installed inside the oil outlet groove to filter impurities in the oil. A sliding groove and a sliding component are arranged inside the spray quenching frame, and a spray quenching assembly is located inside the sliding component. The spray quenching assembly is used to spray quench the rolling mill rolls.

[0008] In a preferred embodiment of this utility model, limiting strips are provided on both sides of the placement frame, and a limiting rail is provided on the inner side of the support column, with the limiting strips and the limiting rail being slidably connected.

[0009] In a preferred embodiment of the present invention, the filter assembly includes a sliding frame, which is slidably connected to the oil outlet groove, and a filter screen is provided on the inner side of the sliding frame.

[0016] Beneficial effects:

[0017] 1. Quenching oil is extracted from the quenching oil tank by a water pump, and then sprayed onto the rolls through a nozzle. One side of the rotating roll is driven to rotate by a first motor, while the other side rotates by self-heating, thereby rotating the rolls. A second motor drives the threaded rod to rotate, causing the sliding parts to slide in the sliding groove. In other words, the nozzle moves above the rolls, thus covering and spraying the rolls to ensure the quenching effect.

[0018] 2. After the quenching oil is sprayed, it flows into the oil tank through the connecting frame. Impurities in the quenching oil are filtered through the filter screen, and the filtered quenching oil falls into the oil receiving tank for collection. This ensures the quality of the recycled quenching oil and eliminates the need for subsequent cleaning of impurities.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Please refer to Figures 1-4This utility model discloses a heat treatment quenching device for rolling mill rolls, comprising a base 1 and a placement frame 2. The base 1 is the bottom mounting structure of the device, used for mounting the overall structure. The placement frame 2 is the placement structure for placing the rolling mill rolls. Support columns 11 are arranged around the base 1, and the support columns 11 are the mounting structures. A quenching frame 12 is arranged on the top of the support columns 11, and the quenching frame 12 is the quenching structure for quenching the rolling mill rolls in the placement frame 2. A connecting frame 3 is arranged at the bottom of the placement frame 2, and the connecting frame 3 is fixedly connected to the bottom of the placement frame 2. The base 1 has two electric push rods 31 on its upper sides. The electric push rods 31 are connected to the bottom sides of the connecting frame 3. The electric push rods 31 push the connecting frame 3 and the placement frame 2, so that the placement frame 2 is aligned with the bottom of the spray quenching frame 12, thereby blocking the splashed and splattered quenching oil. The placement frame 2 has limit strips 23 on both sides and a limit rail 13 on the inner side of the support column 11. The limit strips 23 and the limit rail 13 are slidably connected. The limit rail 13 limits the limit strips 23, thereby keeping the placement frame 2 stable when it is raised and lowered.

[0028] Two rotating rollers 21 are arranged inside the placement frame 2. A first motor 22 is arranged on one side of the placement frame 2. The first motor 22 is connected to one side of the rotating roller 21. That is, the roller is placed on the two rotating rollers 21. One side of the rotating roller 21 is driven to rotate by the first motor 22, and the other side of the rotating roller 21 rotates by self-heating, thereby making the roller rotate. An oil outlet groove 32 is arranged on the inner side of the bottom of the connecting frame 3. A filter assembly is arranged inside the oil outlet groove 32. The filter assembly is used to filter impurities in the oil. The filter assembly includes a sliding frame 33, which is slidably connected to the oil outlet groove 32. A filter screen 34 is provided inside the frame 33, and an oil receiving groove 14 is provided on the inner side above the base 1. The oil receiving groove 14 is placed directly on the inner side above the base 1 and can be removed. The oil receiving groove 14 is located directly below the oil outlet groove 32, that is, it is slidably installed in the oil outlet groove 32 through the sliding frame 33, which is to install the filter screen 34. After the quenching oil is sprayed, it flows into the oil outlet groove 32 through the connecting frame 3. The filter screen 34 filters the impurities in the quenching oil, and the filtered quenching oil falls into the oil receiving groove 14 for collection. Then, the impurities on the filter screen 34 are cleaned by removing the sliding frame 33.

[0029] The inner side of the spray quenching frame 12 is provided with a sliding groove 4 and a sliding member 41. A spray quenching assembly is provided inside the sliding member 41. The spray quenching assembly is used to cover and quench the roll. The sliding member 41 and the sliding groove 4 are slidably connected. The spray quenching assembly includes a nozzle 44. A quenching oil tank 15 and a water pump 5 are provided above the spray quenching frame 12. The quenching oil tank 15 stores quenching oil. The water pump 5 is connected to the quenching oil tank 15 at its pumping point. A hose 51 is provided at the water outlet of the water pump 5, and the hose 51 is connected to the nozzle 44. A threaded rod 42 is provided on one side inside the sliding groove 4, and a threaded end 45 is provided on one side of the sliding member 41. The threaded rod 42 is threadedly connected to the threaded opening 45. A second motor 43 is installed on one side of the outer side of the spray quenching frame 12. The second motor 43 is connected to the threaded rod 42. The water pump 5 draws quenching oil from the quenching oil tank 15 and delivers it to the nozzle 44 through the hose 51. The nozzle 44 is located directly above the roll, so that the roll is sprayed and quenched through the nozzle 44. The second motor 43 drives the threaded rod 42 to rotate, so that the sliding part 41 slides in the sliding groove 4. That is, the nozzle 44 moves above the roll, so that the roll is covered and sprayed, ensuring the spray quenching effect of the roll.

[0030] The working principle of this utility model is as follows: By placing the roll on two rotating rollers 21, the connecting frame 3 and the placement frame 2 are pushed by the electric push rod 31, so that the placement frame 2 aligns with the bottom of the spray quenching frame 12, thereby blocking the splashed and splattered quenching oil. The limiting rail 13 limits the limiting strip 23, thereby keeping the placement frame 2 stable when it is raised and lowered. The quenching oil in the quenching oil tank 15 is drawn by the water pump 5 and delivered to the nozzle 44 through the hose 51. The nozzle 44 is located directly above the roll, that is, the roll is sprayed and quenched through the nozzle 44. One rotating roller 21 is driven to rotate by the first motor 22, and the other rotating roller 21 is driven to rotate by the first motor 22. The self-heating mechanism rotates the roll, which in turn drives the threaded rod 42 to rotate via the second motor 43. This causes the sliding member 41 to slide in the sliding groove 4, allowing the nozzle 44 to move above the roll and cover it with spray quenching solution, ensuring the quenching effect. The sliding frame 33 is slidably installed in the oil outlet groove 32, which is where the filter screen 34 is installed. After the quenching oil is sprayed, it flows into the oil outlet groove 32 through the connecting frame 3. The filter screen 34 filters out impurities in the quenching oil, and the filtered quenching oil falls into the oil receiving groove 14 for collection. Then, the sliding frame 33 is removed to clean the impurities on the filter screen 34.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
