Description
Technical Field
[0001] The utility model belongs to the technical field of rolling mill guides, and in particular relates to a rear half guide with a roller wheel added. Background Art
[0002] A guide is a device installed before and after the roll hole during the steel rolling process to help the rolled piece enter and exit the roll hole accurately and stably in a predetermined direction and state.
[0003] The installation position of the rear half guide is before the wire laying machine for steel rolling, because the rear end outlet is the laying tube of the laying machine, the speed of the rolled piece can reach 120m / s, the temperature is high and the vibration is large, which causes the wear of the rear half guide to be very serious. Usually, it needs to be replaced in a day or even a shift. Therefore, a rear half guide with a roller is needed. Utility Model Content
[0004] The purpose of the utility model is to provide a rear half guide with a simple structure and reasonable design in order to solve the above problems.
[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:
[0006] A rear half guide with rollers installed comprises a left rear half guide and a right rear half guide, five rollers are arranged between the left rear half guide and the right rear half guide, and a refueling assembly is arranged on one side of the five rollers.
[0007] As a further optimization scheme of the utility model, three of the rollers are horizontally arranged in the front middle section of the rear half guide, and the other two rollers are arranged up and down and at the end of the rear half guide outlet.
[0008] As a further optimization scheme of the utility model, the refueling assembly includes a roller shaft arranged between the left rear half guide and the right rear half guide, the roller is rotatably sleeved on the roller shaft, one end of the roller shaft is provided with an oil pipe joint, and the other end of the oil pipe joint is connected to an automatic refueling oil pump.
[0009] As a further optimization solution of the utility model, two symmetrically arranged bearings are arranged between the roller shaft and the roller, and an oil separator ring sleeved on the roller shaft is arranged between the two bearings.
[0010] As a further optimization solution of the utility model, a roller shaft gasket is arranged between the roller shaft and the left rear half guide.
[0011] As a further optimization solution of the utility model, one end of the roller shaft is sleeved with a washer that fits with the left rear half guide, and one end of the roller shaft is threadedly connected with a locking nut that cooperates with the washer.
[0012] The beneficial effect of the utility model is that in the utility model, a pair of rollers are arranged up and down, and a pair of rollers are arranged at the end of the rear half guide outlet, so that the wear of the rolled piece can be prevented when it passes at high speed, and three groups of rollers are installed at the friction force points of the rolled piece in the front middle section of the rear half guide to ensure that the rolled piece is in contact with at least one side of the roller under unstable conditions, so that the wear of the half guide is reduced, thereby reducing the replacement frequency of the half guide. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In the figure: 1. locking nut; 2. washer; 3. roller shaft washer; 4. bearing; 5. oil distributor ring; 6. roller; 7. roller shaft; 8. oil pipe joint; 9. right rear half guide; 10. left rear half guide. DETAILED DESCRIPTION
[0017] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0018] Example 1
[0019] like Figure 1 , Figure 2 As shown, a rear half guide with rollers installed includes a left rear half guide 10 and a right rear half guide 9, and five rollers 6 are arranged between the left rear half guide 10 and the right rear half guide 9, wherein three rollers 6 are arranged horizontally in the front middle section of the rear half guide, and the other two rollers 6 are arranged up and down and arranged at the outlet end of the rear half guide. By a pair of rollers 6 arranged up and down, and a pair of rollers 6 arranged at the outlet end of the rear half guide, it is possible to prevent the wear of the rolled piece when it passes at a high speed, and three groups of rollers are installed at the friction force point of the rolled piece in the front middle section of the rear half guide to ensure that the rolled piece contacts at least one side of the roller in an unstable state, so that the wear of the half guide is reduced, thereby reducing the replacement frequency of the half guide.
[0020] like Figure 2 , Figure 3As shown, one side of the five rollers 6 is provided with a refueling assembly, which includes a roller shaft 7 arranged between the left rear half guide 10 and the right rear half guide 9, a roller shaft gasket 3 is arranged between the roller shaft 7 and the left rear half guide 10, two symmetrically arranged bearings 4 are arranged between the roller shaft 7 and the roller 6, an oil dividing ring 5 sleeved on the roller shaft 7 is arranged between the two bearings 4, the roller 6 is rotatably sleeved on the roller shaft 7, an oil pipe joint 8 is arranged at one end of the roller shaft 7, a gasket 2 that fits the left rear half guide 10 is sleeved at one end of the roller shaft 7, a locking nut 1 that matches the gasket 2 is threadedly connected to one end of the roller shaft 7, and an automatic refueling oil pump is connected to the other end of the oil pipe joint 8, and lubricating oil can be automatically added to the bearing 4 through the oil pipe joint 8 by the oil pump, and the bearing 4 can be evenly and fully lubricated through the internal oil dividing ring 5 by adding dry oil or oil gas, so as to ensure the normal use of the roller 6 when running at high speed.
[0021] This product has been verified through online use. While ensuring lubrication, only the end pair of rollers need to be replaced in three days, and the effect is very good.
[0022] It should be noted that, when the rear half guide with rollers is in use, the workpiece passes through the three groups of rollers 6 on the left rear half guide 10 and the right rear half guide 9, and then passes through the pair of rollers 6 at the outlet ends of the left rear half guide 10 and the right rear half guide 9, to ensure that the workpiece is in contact with at least one side of the roller 6 under unstable conditions, and in the process of exporting, the lubricating oil can be automatically added to the bearing 4 through the oil pipe joint 8 by the oil pump, and the bearing 4 can be evenly and fully lubricated through the internal oil ring 5 by adding dry oil or oil gas, to ensure the normal use of the roller 6 when running at high speed.
[0023] 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 patent of the utility model. 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.
