Abstract
The utility model belongs to the field of metallurgical equipment, particularly relates to a quick roll change device of a hot rolling mill, which comprises a frame. A longitudinal sliding guide rail and a longitudinal oil cylinder are fixed to each of two sides of the frame, and a pair of clamping mechanism are slidably fitted between the longitudinal sliding guide rails, positioned at the ends of the longitudinal oil cylinders and driven by the same. Each clamping mechanism comprises a slider, clamping cylinders are arranged on the sliders disposed in parallel, and clamping claws are arranged at the ends of clamping cylinder rods of the clamping cylinders. The quick roll change device is simple and compact in structure, safe and reliable in performance, convenient in maintenance and quick in roll change.
Description
Technical field
The utility model belongs to field of metallurgical equipment, especially a kind of hot-rolling mill fast roll changing device.
Background technology
In field of metallurgical equipment, particularly the hot rolling unit is realized in the roll change, during two roller hot-rolling mill roll changes universal-joint spindle milling train end enclasping spindle nose, location existence because of causing roll spindle nose upright position, roll wear are changed thereupon, make roll spindle nose and universal-joint spindle union end be in diverse location, draw and wear the roll change inconvenience, influence roll change speed etc. and rush topic.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, performance is safe and reliable, hot-rolling mill fast roll changing device that can fast roll changing.
The technical scheme that realizes the utility model purpose is as follows:
Hot-rolling mill fast roll changing device, comprise frame, the frame both sides are fixed with longitudinal sliding motion guide rail and vertical oil cylinder, be sliding combined with a pair of clamping device between the longitudinal sliding motion guide rail, clamping device is located at the end of vertical oil cylinder by vertical hydraulic oil cylinder driving, clamping device comprises the slide block that be arranged in parallel, and slide block is provided with the clamping oil cylinder, and the clamping cylinder boom end of clamping oil cylinder is provided with gripper jaw.
Described gripper jaw is the V-type pawl.
Adopted such scheme, the longitudinal sliding motion guide rail helps sliding up and down of clamping device, vertically oil cylinder is used to regulate and adds the lengthwise position of holding mechanism, finds the optimum position of clamping roll shaft, and clamping device comprises the slide block that be arranged in parallel, sliding up and down of clamping device utilizes slide block to realize on the longitudinal sliding motion guide rail, clamping device also comprises the clamping oil cylinder, and the clamping oil cylinder provides chucking power for gripper jaw clamping roll shaft, and gripper jaw is the V-type pawl, can better be stable roll shaft is played clamping action, safe and reliable.
Benefit of the present utility model is simple in structure, compact, and performance is safe and reliable, and is easy to maintenance, and roll change is quick.
