Embodiment Construction

[0013] Referring to the accompanying drawings, a multi-roller ring of a section steel straightening machine is quickly aligned and locked at the same time. 5. The moving side taper shaft 6, the moving side bearing seat 7, and the hydraulic nut 8 are composed. The fixed side taper shaft 1 is installed on the fixed side bearing seat 2. The tapered end and the end of the roller shaft 5 are threaded. The other end passes through the combined roller ring 4 and the moving side cone shaft 6, the two ends of the combined roller ring 4 are bolted to the tapered hole ring 3, the moving side cone shaft 6 is installed on the moving side bearing seat 7, and the moving side Taper shaft 6 has a taper hole at the end of the taper surface and a guide device. The roller shaft 5 can pass through the mobile side taper shaft 6 and connect with the hydraulic nut 8 along the guide device, so that the fixed side taper shaft 1 and the moving side taper shaft 6 will be connected to each other. The comb...

Abstract

The invention relates to a simultaneous and quick aligning and locking device for a multi-roll ring of a section steel straightener applied in the metallurgical machinery industry. The device consists of a fixed side cone shaft, a fixed side bearing pedestal, cone hole rings, a combined roll ring, a roll shaft, a movable side cone shaft, a movable side bearing pedestal and a hydraulic nut, wherein the fixed side cone shaft is installed on the fixed side bearing pedestal, and the conical surface end of the fixed side cone shaft is in threaded connection with one end of the roll shaft; the other end of the roll shaft passes through the combined roll ring and the movable side cone shaft; the cone hole rings are screwed at two ends of the combined roll ring by bolts; the movable side cone shaft is installed on the movable side bearing pedestal; a cone hole and a guide device are arranged at the end part of the conical surface of the movable side cone shaft; the roll shaft can pass through the movable side cone shaft along the guide device to be connected with the hydraulic nut, so that the combined roll ring is clamped between the fixed side cone shaft and the movable side cone shaft; and the combined roll ring is aligned and quickly locked through the fixed side cone shaft and the movable side cone shaft. The device has novel and scientific concept, long service life and high hydraulic control precision, is convenient to adjust and disassemble and is stable and safe to run synchronously.

Description

technical field [0001] The invention relates to a simultaneous rapid alignment and locking device for multiple roller rings of a roller-type steel straightening machine in the metallurgical machinery industry. Background technique [0002] At present, the roller profile straightening machine is the key equipment in the finishing area of ​​the profile rolling production line, which can straighten various profiles such as H-beams, I-beams, angle steels, and channel steels. The commonly used forms of roller type steel straightening machine are simply supported structure and cantilever structure. Straightening machine with simply supported structure means that the straightening area is between two racks, forming a simply supported beam stress state. Straightening machine with simply supported structure is also called double supporting structure straightening machine. Its advantage is that the frame has high rigidity, light weight, and the two fulcrum bearings are evenly stresse...
