Embodiment 1

[0024] In order to overcome the problems of high wear, low rigidity and poor stability of existing devices, the present invention provides such as figure 1 and figure 2 The shown one kind of taper sleeve self-adaptive external support for 20-high high-tension rolling, that is, a kind of swing door fixed at both ends, taper sleeve self-adaptive external support, the support has high rigidity and good stability, and can It can automatically align and compensate the wear gap, and can accurately position and limit the cantilever end of the reel. It is suitable for the outer support of the high-tension coiler in the 20-high rolling production line.

[0025] Such as figure 2 As shown, a taper sleeve self-adaptive outer support for 20-high high-tension rolling includes a swing cylinder 1, a bracket 2, and a swing door 4, and the swing cylinder 1 passes through a base 18 arranged on the bracket 2 Fixedly installed on the bracket 2, the piston rod of the swing cylinder 1 is hinged ...

Embodiment 2

[0032] Based on the first embodiment, the outside of the spherical taper sleeve 20 in this embodiment is processed with a tapered hole, the taper of which is the same as that of the cantilever head 22 of the reel 5 . The tapered hole provided can replace the cantilever head 22 to prevent the wear of the cantilever head 22. This tapered sleeve type can fully fit with the cantilever end of the reel, with accurate positioning and good stability.

[0033] The sliding column 15 is provided with a retaining ring 21 to prevent the spherical taper sleeve 20 from falling out.

[0034] Spherical tapered sleeve 20 is installed inside sliding column 15, and its convex spherical surface is equal to the curvature of the spherical surface of sliding column 15. The outer side of spherical surface taper sleeve 20 is processed with a tapered hole, and its taper is the same as that of the cantilever head 22 of reel 5. When the swing door 4 is closed, the two cone surfaces fit together, and the r...

Embodiment 3

[0039] Based on the above two embodiments, as image 3 As shown, in the waiting position, the swing cylinder 1 is retracted, the swing door 4 is in an open state, the piston rod 13 is in a retracted state, the locking cylinder 8 is in a retracted state, and the connected locking rod is also in a retracted state. When working, after the diameter expansion of the reel 5 is completed, the piston rod of the swing cylinder 1 is stretched out, and the swing door 4 is pushed to close. After the closing is in place, the piston rod of the locking cylinder 8 is stretched out, and the locking rod 6 is pushed to be set on the taper pin 19, and the swing door 4 is pushed out. The door 4 is locked, and then the piston rod 13 is stretched out, driving the sliding column 15 and the spherical taper sleeve 20 to slide towards the cantilever head 22, utilizing the adaptability of the spherical surface, the spherical taper sleeve 22 is tightly set on the cantilever head 22, and the axial and Radi...

Abstract

The invention provides a taper sleeve adaptive type outer support for 20-roller large tension rolling. The taper sleeve adaptive type outer support comprises a swing oil cylinder, a bracket and a swing door, wherein the swing oil cylinder is fixedly mounted on the bracket through a base arranged on the bracket, a piston rod of the swing oil cylinder is hinged to a support arranged on the swing door, the swing door is positioned in the middle of the bracket, and the swing door and the bracket are in rotating connection through hinge pins; a cylinder body is arranged on the swing door, a cylinder cover is mounted on the inner side of the cylinder body, the piston rod is mounted in the cylinder body, a sliding column is arranged on the swing door, and the sliding column is connected with the piston rod through a screw; the other end of the swing door is connected with a locking rod, the other end of the locking rod is connected with the piston rod locking the oil cylinder, and the locking rod penetrates through a sliding sleeve mounted in a fixed base so as to control the opening and locking of the swing door. The taper sleeve adaptive type outer support is high in rigidity and great in stability, and the taper sleeve has the advantages of being rapidly adjustable and adaptive and can adapt to the rolling work conditions of large tension and high roll weight.

Description

technical field [0001] The invention relates to an auxiliary support device for a coiler in a rolling production line, in particular to a tapered sleeve self-adaptive outer support for 20-high high-tension rolling. Background technique [0002] In the production of plate and strip rolling, it is necessary to use uncoilers and coilers to uncoil and coil coils. The external support device is used as an accessory equipment of the uncoiler and coiler to support the cantilever end of the reel during the rolling process, so as to avoid large deflection of the reel under the action of large tension and large coil weight, which will affect the service life of the equipment . The main forms of existing external support devices are swinging door type and connecting rod lifting type. The supporting parts of the two types are cantilever structures, which are not rigid enough, which is not conducive to stable rolling with constant tension, especially difficult to apply to 20-high rollin...
