Description

Technical Field

[0001] The utility model relates to a water cooling device for the main bearing seat of a dual-output or single-output ball press machine, which solves the problem that the high temperature generated by the main bearing of a dual-output or single-output ball press machine for dry powder and wet powder has nowhere to be released during continuous high-pressure and heavy-load production, resulting in high temperature and short service life of the ball press machine bearings. The device ensures that the lubricating oil of the bearing is not diluted by high temperature and loses the mucous membrane protection, and that the bearing works continuously within the standard temperature. Background Art

[0002] The current dry powder and wet powder briquette machine has no main bearing water cooling system. In the actual working environment, the four main bearings of the briquette machine roller are subject to two forces. On the one hand, the reaction force of the material being squeezed on the roller is transmitted to the bearing; on the other hand, the hydraulic system cylinder generates a huge driving force acting on the roller bearing. In order to overcome the reaction force generated by the material extrusion, the relative forces of the two aspects are finally concentrated on the main bearing. The bearings need to generate heat when they rotate frictionally under the huge double-action pressure. As long as the machine is working and rotating, this heat is accumulated every moment. Excessive temperature will cause the lubricating oil of the bearing to be diluted by the high temperature and no oil film can be formed. It fails to play a lubricating role, and the dilution of the lubricating oil destroys the service life of the four main bearings. In the continuous high-pressure and heavy-load production, the high temperature generated by the actual accumulated temperature of the main bearings has nowhere to be released, which exceeds the limit temperature of the bearings by several times of 80 degrees. Therefore, the high temperature of the ball press bearings and the short service life caused by the high temperature are very common phenomena. Water cooling must be used to solve the problem of the machine bearings working at high temperatures. It is necessary to ensure that the lubricating oil of the bearings is not diluted by high temperature and loses the mucous membrane protection, ensure that the bearing material is not worn due to reduced lubrication protection, and ensure that the bearings can work continuously for a long time within the standard temperature. Therefore, it is urgent to solve the problem of high temperature of the main bearings. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide a water cooling device for the main bearing seat of a double-output and single-output ball press machine, which can ensure that the temperature of the main bearing is lowered during continuous production and controlled within a normal range below 80 degrees, ensure that the lubricating oil of the bearing is not diluted by high temperature, and ensure that the hardness of the bearing material of the dry powder and wet powder ball press machine is not affected, thereby ensuring that the long-term service life of the main bearing exceeds several times the current one.

[0004] The purpose of the utility model is achieved as follows: a water cooling device for the main bearing seat of a dual-output single-output ball press machine, comprising a water tank, a water pump arranged in the water tank, a high-pressure water pipe connected to the output end of the water pump, various branch high-pressure water pipes connected to the high-pressure water pipe, a return water main pipe connected to the water tank, and various branch return water pipes connected to the return water main pipe. A radiator is also installed on the return water main pipe, and a fan is installed next to the radiator facing the radiator. A main bearing seat circulating water chamber is provided on the third main bearing seat and the fourth main bearing seat. A circulating water inlet hole and a circulating water outlet hole are provided on the main bearing seat circulating water chamber. A flow diversion partition is provided in the main bearing seat circulating water chamber between the circulating water inlet hole and the circulating water outlet hole. The circulating water inlet hole is connected with each branch high-pressure water pipe, and the circulating water outlet hole is connected with each branch return pipe. A main bearing outer ring is installed in the inner hole of the main bearing seat, and the main bearing outer ring is close to the main bearing seat circulating water chamber.

[0005] The specific structure of the circulating water chamber of the main bearing seat is as follows: a circle of circulating water grooves is opened on the inner wall of the preset hole of the main bearing seat, and a cylindrical sealing sleeve is arranged outside the circulating water groove. The cylindrical sealing sleeve is made of a cylindrical steel pipe. The cylindrical steel pipe is pressed into the preset hole of the main bearing seat and covers the opening of the circulating water groove. It is sealed together with the circulating water groove to form the circulating water chamber of the main bearing seat. The circumferential ports at both ends of the cylindrical sealing sleeve are welded and sealed with the main bearing seat body. After the cylindrical sealing sleeve is pressed into the preset hole of the main bearing seat and sealed, the circulating water groove becomes a sealed circulating water chamber of the main bearing seat.

[0006] The circulating water troughs are at least two circulating water troughs arranged in parallel. A flow diversion partition is provided in each circulating water trough, and a circulating water inlet hole and a circulating water outlet hole are provided on both sides of the flow diversion partition. The circulating water inlet hole passes through at least two circulating water troughs, and the circulating water outlet hole also passes through at least two circulating water troughs. The circulating water inlet hole and the circulating water outlet hole ensure that the at least two circulating water troughs arranged in parallel are connected to each other.

[0007] A temperature display is installed on each branch return pipe.

[0008] The water pump is also connected to a circuit controller.

[0009] The technical solution of this utility model solves the problem of eliminating old and backward designs. The dry powder ball press machine, wet powder ball press machine, speed reducer dual-output ball press machine, speed reducer single-output ball press machine can reduce the temperature of the main bearing during continuous long-term production work, and control the bearing temperature within the normal range below 80 degrees. Under the condition of long-term continuous work, the lubricating oil of the bearing is not diluted by high temperature, the hardness of the bearing material of the dry powder and wet powder ball press machine is not affected, and the long-term service life of the main bearing of the machine is several times longer than the current one. In the continuous high-pressure and heavy-load production, the high temperature generated by the main bearing of the dry powder and wet powder dual-output or single-output ball press machine has nowhere to be released, which leads to high temperature and short service life of the ball press machine bearing. It ensures that the lubricating oil of the bearing is not diluted by high temperature and loses the mucous membrane protection, and ensures that the bearing works continuously within the standard temperature.

[0013] like Figure 1 、 2 As shown in Figure 3, a water cooling device for the main bearing seat of a dual-output single-output ball press machine includes a water tank 1, a water pump 2 arranged in the water tank 1, a high-pressure water pipe 3 connected to the output end of the water pump 2, various branch high-pressure water pipes 8 connected to the high-pressure water pipe 3, a return water main pipe 4 connected to the water tank 1, and various branch return water pipes 7 connected to the return water main pipe 4. A radiator 6 is also installed on the return water main pipe 4, and a fan 5 is installed next to the radiator 6. The first main bearing seat 9, the second main bearing seat 10, the third main bearing seat 11 and the fourth main bearing seat 12 are connected to the main pipe 4. A main bearing seat circulating water chamber 13 is provided on the main bearing seat 12. A circulating water inlet hole 18 and a circulating water outlet hole 19 are provided on the main bearing seat circulating water chamber 13. A flow diversion partition 20 is provided in the main bearing seat circulating water chamber 13 between the circulating water inlet hole 18 and the circulating water outlet hole 19. The circulating water inlet hole 18 is connected to each branch high-pressure water pipe 8, and the circulating water outlet hole 19 is connected to each branch return water pipe 7. A main bearing outer ring 15 is installed in the main bearing seat inner hole 14, and the main bearing outer ring 15 is close to the main bearing seat circulating water chamber 13.

[0014] The specific structure of the main bearing seat circulating water chamber 13 is as follows: a circle of circulating water groove 22 is opened on the inner wall of the preset hole 21 of the main bearing seat, and a cylindrical sealing sleeve 23 is arranged outside the circulating water groove 22. The cylindrical sealing sleeve is made of a cylindrical steel pipe. The cylindrical steel pipe is pressed into the preset hole of the main bearing seat and covers the opening of the circulating water groove 22. It is sealed together with the circulating water groove 22 to form the main bearing seat circulating water chamber 13. The circumferential ports at both ends of the cylindrical sealing sleeve are welded and sealed to the main bearing seat body 24 through the steel pipe welding seam 25. After the cylindrical sealing sleeve is pressed into the preset hole of the main bearing seat and sealed, the circulating water groove 22 becomes the sealed main bearing seat circulating water chamber 13.

[0015] The circulating water troughs 22 are at least two circulating water troughs 22 arranged in parallel. A flow diversion partition 20 is provided in each circulating water trough 22. A circulating water inlet hole 18 and a circulating water outlet hole 19 are provided on both sides of the flow diversion partition 20. The circulating water inlet hole 18 passes through at least two circulating water troughs 22, and the circulating water outlet hole 19 also passes through at least two circulating water troughs 22. The circulating water inlet hole 18 and the circulating water outlet hole 19 ensure that the at least two circulating water troughs 22 arranged in parallel are connected to each other.

[0016] A temperature display 16 is installed on each branch return pipe 7. A circuit controller 17 is also connected to the water pump 2.

[0017] The water pump 1 pressurizes water into the high-pressure water pipe 3 and each branch high-pressure water pipe 8, and enters the circulating water inlet holes 18 inside the four main bearing seats through each branch high-pressure water pipe 8, and then enters the circulating water cavity 13 of the main bearing seat through the circulating water inlet holes 18. The cooling water circulates in the circulating water cavity 13 of the main bearing seat for one circle, and conducts away the heat generated by the bearing. The hot water is pressed into the radiator 6 through the return water main pipe 4 and each branch return water pipe 7. The return water temperature is reduced by the radiator 6 and the fan 5, and finally flows into the water tank 1, thus completing the water cooling cycle process.

[0018] The automatic circulating water cooling system works synchronously with the machine, and no manual operation or manual control is required. During the continuous production process of the dry powder and wet powder briquette machine, the bearings are under pressure and generate heat. This heat accumulates and rises continuously according to the working time. The main bearings are automatically cooled according to the water circulation heat dissipation technology to ensure that the bearings work continuously at a constant temperature, the viscosity of the lubricating oil is not affected by high temperature, and the core components of the bearings are fully guaranteed to work for a long time in a constant temperature environment.
