Embodiment Construction
[0009] For the rewinding hollow mandrel jacking device of the rewinding machine, the implementation of the present invention is relatively simple, and the jacking and resetting liquid cylinder 4 can be selected from standard parts, and other parts can be completed by conventional machining methods. The bracket 5 can be cast and formed by metal material, the positioning rod sliding bearing sleeve is fixed with the bracket 5 into one body, and a guide key 2 is provided on the jacking and positioning rod 1, so that the jacking and positioning rod 1 can only be axially displaced but not rotated. A locking screw is provided on the retaining connecting sleeve 7 on the jacking and positioning rod 1. When the jacking and positioning rod 1 is adjusted to reach the working position, the positioning rod 1 and the connecting sleeve are locked together with the locking screw. The jacking devices are used in pairs when working, that is to say, two jacking devices should be correspondingly in...

A rewinding hollow spindle butting device of a rewinding machine is mainly formed by a butting positioning rod 1, positioning rod sliding bearings 3, a butting reset hydraulic cylinder 4, a support 5, a retentive connecting sleeve 7 and a central butting head 8. Two sliding bearings 3 are arranged in a sleeve on the lower portion of the support 5, the butting positioning rod 1 is installed in the sliding bearings 3, the central butting head 8 is installed at the right end of the butting positioning rod 1, the butting reset hydraulic cylinder 4 is arranged below the support 5, and the retentive connecting sleeve 7 is arranged on the butting positioning rod 1 on the right of the support 5. A cylinder body of the butting reset hydraulic cylinder 4 is connected onto the sleeve below the support 5 through a hinge, a piston rod connecting hinge 6 is connected with the retentive connecting sleeve 7, and a guide key 2 is arranged on the butting positioning rod 1. The rewinding hollow spindle butting device of the rewinding machine is simple in structure, convenient to use and maintain, flexible to operate and safe and reliable in butting positioning, can be adjusted randomly in an effective length of the butting positioning rod, reduces labor intensity, and improves working efficiency.
Description
technical field [0001] The invention is mainly used for the clamping and positioning of the hollow mandrel for rewinding thin coils, and is a clamping device for the rewinding hollow mandrel of a rewinding machine. Background technique [0002] The raw roll of the thin coil is often rough when initially rolled, and the tightness of the roll is often inconsistent, and the damaged thin coil is rolled into the original roll. After rewinding by the rewinding machine, the damaged thin coil parts are removed and the consistent tightness of the coils is ensured as much as possible, so as to ensure the cutting quality. The rewinding hollow mandrel used in the rewinding machine is usually composed of multiple short mandrels made according to the slitting width. In order to prevent axial movement, the two ends of the rewinding hollow mandrel must be tightly positioned. The traditional way of jacking is to use a manually operated rotating screw to drive the jack to tighten or loosen, ...
