Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention will be further described:

[0012] Such as figure 1 As shown, a roll synchronizer for a tempering machine includes a frame 1, a static part, a moving part and work rolls.

[0013] The static part includes a pair of bearing housings 2 fixed on the frame and synchronous rollers 7 installed in the bearing housings at both ends. Since the two ends of the synchronous rollers are fitted with bearings, the synchronous rollers can rotate freely.

[0014] The moving part comprises a flat plate 5, and the flat plate is a gate shape. Both sides of the flat plate 5 are slidably installed on the frame through the linear guide rail 6. The linear guide rail is composed of a chute and a slider. The specific style belongs to the existing mature technology, and the specification and model can be selected according to actual needs. A pair of oil cylinders are arranged between the frame and the plate, marked as the fi...

Abstract

The invention discloses a rotary roll synchronizer for a levelling machine and belongs to the field of steel rolling machinery. The rotary roll synchronizer comprises a rack, a static part, a moving part and a working roll, wherein the static part comprises a pair of bearing seats fixed on the rack and synchronous rolls of which two ends are arranged in the bearing seats; the moving part comprises a flat plate; two sides of the flat plate are slidably arranged on the rack through a linear guide rail; two ends of the synchronous rolls are matched with the flat plate through gear rack structures; and a pair of oil cylinders are arranged between the rack and the flat plate and are used for driving the flat plate to move linearly; and the working roll and the synchronous rolls are parallelly arranged on the flat plate. By utilizing such a structure, the two oil cylinders are enabled to ascend and descend synchronously, so that anti-wrinkle rolls or anti-vibration rolls can be kept at horizontal positions, and the band steel rolling precision can be improved.

Description

technical field [0001] The invention relates to a synchronizer, in particular to a roller synchronizer for a leveling machine. Background technique [0002] In the rolling process, an anti-wrinkle roll and an anti-vibration roll are respectively provided on the entrance side and the exit side of the tempering machine. They are respectively controlled by two hydraulic cylinders and a slideway to rise and fall. The hydraulic cylinder is the power source. The position is locked by these hydraulic cylinders. In the process of use, due to the possible time difference between the two hydraulic cylinders in the actual operation process, the anti-wrinkle roll and the anti-vibration roll are tilted due to the asynchrony of the hydraulic cylinders, which in turn affects the rolling accuracy of the strip. Make improvements. Contents of the invention [0003] The object of the present invention is to provide a roll synchronizer for a skin pass mill, which can keep the two transmissi...
