Description

Technical Field

[0001] The present application relates to the technical field of straightening machines, and in particular to a pressure roller lubrication structure for straightening machines. Background Art

[0002] Straightening machine is a kind of equipment widely used in various industrial fields. It is mainly used to accurately adjust the straightness of materials to meet the needs of production processes. With the continuous advancement of science and technology and the rapid development of industry, straightening machines can straighten many materials such as metal profiles, bars, pipes, wires, etc.

[0003] The straightening machine uses rollers to squeeze bars and other materials to change their straightness. The main types of straightening machines include pressure straightening machines, balance roller straightening machines, shoe roller straightening machines, rotary reverse bending straightening machines, etc. Most straightening machines are equipped with two rows of rollers, and the number of rollers in each group is different. The materials of different diameters are straightened by changing the angle of the two rollers.

[0004] Usually, both ends of the roller are rotatably mounted on the bearing seat on the machine body through bearings, and the bearing seat is usually provided with a mounting cavity for the bearing. In actual use, it is necessary to regularly inject grease into the bearing to ensure that the roller can work normally. However, in the actual operation process of injecting grease, excess grease is easy to overflow directly from the mounting cavity. The overflowed grease needs to be cleaned in time, so the relevant staff need to inject grease and clean it at the same time, which is inconvenient to use. Utility Model Content

[0027] The following is combined with Figure 1-2 This application is described in further detail.

[0028] The embodiment of the present application discloses a pressure roller lubrication structure for a straightening machine.

[0029] Reference Figure 1 and Figure 2 A roller lubrication structure for a straightening machine includes an oil filling hole 3 provided on a bearing seat 2, the oil filling hole 3 is connected to a mounting cavity 21 on the bearing seat 2 for mounting a bearing, and an oil filling nozzle 4 is also installed at one end of the oil filling hole 3 away from the mounting cavity 21, and grease can be injected into the mounting cavity 21 through the oil filling nozzle 4 through the oil filling hole 3. An oil guide groove 5 is also provided in the bearing seat 2, and a seal 6 is detachably provided at the end of the oil guide groove 5 away from the mounting cavity 21. The oil guide groove 5 is connected to a plurality of mounting cavities 21, and the grease injected into the mounting cavity 21 can enter the oil guide groove 5. The seal 6 plays a sealing role, so that the injected grease can be stored in the bearing seat 2, so that the bearing can be lubricated, and in the process of lubricating the bearing, the grease is not easy to overflow from the bearing seat 2. When it is necessary to clean up the excess grease, the waste oil in the bearing seat 2 is discharged by removing the seal 6, thereby improving the convenience of bearing lubrication and maintenance operations.

[0030] The bearing seat 2 is in the shape of a rectangular parallelepiped as a whole, and one end of a plurality of rollers 1 is rotatably mounted on the bearing seat 2 in sequence through bearings along the length direction of the bearing seat 2. The mounting cavity 21 is in the shape of a cylindrical tube as a whole, the length direction of the mounting cavity 21 is parallel to the length direction of the roller 1, and the bearing is arranged in the mounting cavity 21. A sealing ring 22 is also arranged on the bearing seat 2, and the sealing ring 22 is located at both ends of the mounting cavity 21, so as to prevent the injected grease from flowing out directly from the mounting cavity 21 as much as possible.

[0031] The oil guide groove 5 includes a first oil groove 51 and a second oil groove 52, wherein a plurality of first oil grooves 51 are provided corresponding to the mounting cavity 21, and a single second oil groove 52 is provided. The second oil groove 52 is opened through the bearing seat 2 along the length direction of the bearing seat 2, the length direction of the first oil groove 51 is perpendicular to the length direction of the mounting cavity 21 and the length direction of the second oil groove 52, and one end of the first oil groove 51 is connected to the mounting cavity 21 corresponding to itself, and the other end of the first oil groove 51 is connected to the second oil groove 52. The seal can be set as a rubber plug or a screw plug with a sealing effect. In this embodiment, the seal is set as a screw plug, which has certain corrosion resistance and durability, and can improve the service life. The screw plug is installed at both ends of the second oil groove 52 through a threaded structure, and the mounting hole on the screw plug is set as a hexagonal hole. The use of a hexagonal hole can increase the force area when the screw plug is installed, so that it can withstand a larger load, thereby improving the tightness of the seal 6 and the bearing seat 2.

[0032] When injecting new grease, first install the seal 6 on the bearing seat 2, and then the relevant personnel inject grease into the installation cavity 21 along the oil filling hole 3 through the oil filling nozzle 4. At this time, the grease will accumulate in the oil guide groove 5 and the installation cavity, so as to lubricate the bearing. When the grease needs to be drained, first place the receiving container close to the bearing seat 2, and then remove the seal 6 from the bearing seat 2, so that the waste oil in the bearing seat 2 is discharged to the outside of the bearing seat 2 and discharged into the receiving container; then inject cleaning liquid through the oil filling nozzle 4 to clean the residual waste oil in the installation cavity 21 and the oil guide groove 5, and finally blow dry the inside of the bearing seat 2 with high-pressure gas, waiting for the re-injection of new grease.

[0033] The implementation principle of the roller lubrication structure for a straightening machine in the embodiment of the present application is as follows: by providing an oil guide groove 5 and a seal 6, the grease injected through the oiling nozzle 4 can be stored in the bearing seat 2, thereby minimizing the phenomenon of grease directly overflowing from the mounting cavity 21 during the bearing lubrication process; through subsequent operations such as disassembling the seal 6 and cleaning the inside of the bearing seat 2, the waste oil can be discharged more conveniently and the inside of the bearing seat 2 can be cleaned, thereby improving the convenience of bearing lubrication.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
