Description
Technical Field
The utility model belongs to the technical field of the hot rolling coiling equipment, concretely relates to hot rolling reel dabber.
Background
Generally speaking, the hot-rolled winding drum mandrel comprises a mandrel body and a dry oil lubrication part, the working condition of the hot-rolled winding drum is very bad when the hot-rolled winding drum works, the hot-rolled winding drum is impacted by large impact, the rotating speed is high, and the internal temperature of the winding drum reaches 200-300 ℃. Therefore, the service life of the hot-rolling winding drum is directly influenced by the quality of oil supply of the dry oil lubrication part.
In the dry oil lubrication part of the existing hot-rolled winding drum mandrel, an interlayer dry oil pipe is arranged in the mandrel to form two oil paths to reach a dry oil distribution valve, and the two oil paths are divided into a plurality of oil paths by the distribution valve to reach the working inclined plane of the mandrel, as shown in fig. 4 to 6. The hot rolling reel mandrel with the structure has high requirement on the processing precision of the inner hole for installing the dry oil pipe, high processing cost and high assembly requirement, for example, a sealing element can not be damaged in the assembly process, the dry oil pipe must be tightly pressed in the inner cavity of the oil through pipe by using a key top to ensure that the dry oil pipe is not loosened, and the like. Therefore, the oil supply of the conventional dry oil lubrication part is unstable, and the whole winding drum mandrel cannot be lubricated normally by the dry oil easily.
We can see that most of the hot-rolled winding drums of some domestic iron and steel enterprises are forced to be taken out of the machine in advance after the dry oil lubrication part in the winding drum fails. Therefore, how to ensure that the dry oil does not leak is a problem to be solved urgently at present.
Disclosure of Invention
In order to solve the problem that the above-mentioned drier oil that prior art exists leaked, the utility model provides a hot rolling reel dabber, this dabber include dabber body and drier oil feed oil circuit, wherein drier oil feed oil circuit one end and oil filler point intercommunication, the other end be used for with logical oil piece intercommunication, drier oil feed oil circuit is the direct first axial hole of brill and second axial hole on dabber body, at dabber body cylinder court the connecting hole is bored to the direction in first axial hole and second axial hole, makes first axial hole and second axial hole intercommunication, forms drier oil feed oil circuit from this, this drier oil feed oil circuit one end through first axial hole with the oil filler point intercommunication, the other end through the second axial hole with logical oil piece intercommunication.
The oil filler hole is plugged by an oil filler hole plug screw.
The connecting hole is plugged by a connecting hole plug screw.
The dry oil inlet oil path has two paths.
As a preferred embodiment, the two paths of dry oil inlet oil paths are arranged symmetrically to the axis of the mandrel body. The connecting hole is perpendicular to the first axial hole and the second axial hole.
The utility model discloses hot rolling reel dabber has cancelled the inside grease pipe of dabber among the prior art and the sealing member on the grease pipe, directly sets up first axial hole and second axial hole on the dabber body and makes two axial holes intercommunication through the connecting hole, forms independent oil feed oil circuit from this, need not to use the sealing member, and anti high temperature and shock resistance are showing and are improving, do not have the grease leakage problem, therefore the fuel feeding is stable. The problem of among the prior art drier oil can't normally carry out the drier oil lubrication because of leaking is solved. Simultaneously the utility model discloses make processing become simple, cost effective reduction.

Detailed Description
The invention is described in detail below with reference to specific embodiments shown in the drawings:
as can be seen from fig. 1, the mandrel body 1 has a first axial hole 11, a second axial hole 12 and a connecting hole 13 therein, wherein the connecting hole 13 is arranged from the cylindrical surface of the mandrel body 1 towards the first axial hole 11 and the second axial hole 12, so that the first axial hole 11 and the second axial hole 12 are communicated, thereby forming the dry oil inlet oil path 2. The oil filler point 3 sets up the tip at first axial hole 11, and the drier oil gets into first axial hole 11, gets into second axial hole 12 through connecting hole 13 from oil filler point 3, and the front end of second axial hole 12 communicates with logical oil piece 4, divides into a plurality of ways with the drier oil and finally reaches the work inclined plane 7 of dabber body 1.
When in processing, a first axial hole 11 and a second axial hole 12 are respectively drilled from two ends of a mandrel body 1 to the middle direction, then a connecting hole 13 is drilled from the cylindrical surface of the mandrel body to the direction of the first axial hole 11 and the direction of the second axial hole 12, so that the first axial hole 11 is communicated with the second axial hole 12 to form a dry oil inlet oil path 2, an oil filling hole 3 is drilled at the position of the first axial hole at the end part of the mandrel body, so that dry oil is filled into the first axial hole 11, then passes through the connecting hole 13 to the second axial hole 12, and finally reaches an oil passing block 4.
The oil filler hole 3 is plugged by the oil filler hole plug screw 5, and the connecting hole 13 is plugged by the connecting hole plug screw 6, so that a sealing piece is not needed.
The utility model discloses because directly form the drier oil feed oil circuit on the dabber body, its anti high temperature and shock resistance are showing and are improving, need not use the sealing member moreover, do not have the drier oil leakage problem, therefore the fuel feeding is stable, can guarantee the normal stable fuel feeding of hot rolling reel dabber at work. Simultaneously the utility model discloses make processing become simple, cost effective reduction.
