Problems solved by technology

Since the manufacturing precision of different drive roll systems is not the same, there are allowable tolerances, which causes some drive roll systems to achieve normal roll change, but most drive roll systems cannot achieve normal roll change. The occurrence of roller failure will seriously increase the auxiliary time and affect the production

Embodiment 1

[0025] In order to ensure that the plate and strip rolling equipment can be realized reliably, conveniently, time-savingly and smoothly every time the drive roller is replaced, the present invention proposes a method such as figure 1 , figure 2 The flat wheel and drum combined axle head supporting device shown specifically refers to the design of a drive roller universal joint supported by two flat wheel assemblies at the front end and two roller assemblies at the rear end at the same time, four The roller assembly constitutes the "two lines and two points" contact form. Among them, the flat wheel assembly is a line contact, which plays a positioning role; the drum wheel assembly is a point contact, which plays a balancing role. This "two-line, two-point" contact form of the shaft head support device can not only accurately position, but also has a follow-up balance function—that is, the drive roller system with different manufacturing precision can adapt to the shaft head s...

Embodiment 2

[0029] Based on the above-mentioned embodiment, in this embodiment, if figure 2 As shown, the left lower supporting roller 5 has the same structure as the right lower supporting roller 8 , including a drum assembly 12 and a flat wheel assembly 11 , and the flat wheel assembly 11 is located at the front end of the drum assembly 12 .

[0030] The left upper supporting wheel 6 has the same structure as the right upper supporting wheel 7, and is a flat wheel assembly 11 and a drum wheel assembly 12, and the flat wheel assembly 11 is located at the front end of the drum wheel assembly 12.

[0031] Such as Figure 4 As shown, the drum assembly 12 at least includes a hinge shaft, a rolling bearing and a drum, and the drum is a drum-shaped roller with a central protrusion at both ends that has been rounded, and is connected to the drive roller when it is in operation. The head is a point contact.

[0032] Such as image 3 As shown, the flat wheel assembly 11 includes at least a hi...

Abstract

The invention provides a flat roller and drum roller combined spindle head supporting device which comprises a left support and a right support. An upper transmission roller universal spindle and a lower transmission roller universal spindle are arranged between the left support and the right support. The lower transmission roller universal spindle is located right below the upper transmission roller universal spindle. The left support and the upper transmission roller universal spindle are connected through an upper left supporting wheel. The left support and the lower transmission roller universal spindle are connected through a lower left supporting wheel. A left drive oil cylinder is connected to the left end of the left support. The right support and the upper transmission roller universal spindle are connected through an upper right supporting wheel. The right support and the lower transmission roller universal spindle are connected through a lower right supporting wheel. A right drive oil cylinder is connected to the right end of the right support. A spindle head is supported through combination of two sets of flat rollers and two sets of drum rollers, and thus the dual linear contact mode and the dual point contact mode are formed; and the supporting wheels are stable and reliable, and both accurate positioning and the servo-balance function can be achieved.

Description

technical field [0001] The invention relates to metallurgical machinery, automation and rolling technology, in particular to a combined flat wheel and drum wheel head supporting device. Background technique [0002] The flat wheel and drum combined shaft head support device is specially used for the support balance and positioning of the main drive universal joint shaft of the strip rolling equipment when changing rolls. [0003] The traditional main drive universal joint shaft adopts the shaft head holding device to realize the support balance and positioning of the universal joint shaft when changing the roll. The shaft head is "locked". The so-called "locking" means that this traditional shaft head holding device can accurately and firmly fix the universal joint shaft in a position. When the equipment is debugged, the position is generally adjusted and fixed based on a set of transmission rollers. After the position is determined, the rest of the transmission roller sys...
