Abstract
The utility model discloses a roll changer, comprising a roll changing stand. A roll changing dolly is arranged in a roll changing track of the roll changing stand. A chain wheel is arranged on the roll changing stand and a chain is arranged on the chain wheel. The chain wheel is connected with a hand-driven chain gear case and the chain is connected with the roll changing dolly. The chain connected with the roll changing dolly is arranged on the roll changing stand, and the roll changing dolly is driven to move on the roll changing stand by the hand-driven chain gear case. Through the motion of the roll changing dolly, roll systems are moved out of a frame, thus realizing mechanization of changing the rolls.
Description
Technical field
The utility model relates to the parts in a kind of rolling mill production line, is specifically related to a kind of changing machine.
Background technology
Changing machine is one of vitals in the cold rolling line, and roller also is crucial parts.In Rolling Production, roller will directly contact with rolling metal, and operating rate is very high sometimes, and roller can wear and tear gradually at work and be directly connected to the productivity ratio of whole production line, the quality and the production cost of product.When roller was worn down to a certain degree, the roller that just needs the use changing machine more to renew just can work on.
Following steel rolling production develops towards high speed, heavy duty, high strength, high rigidity, high accuracy, serialization and automation direction, thus for changing machine can be fast, accurately, roll change easily has higher requirement.Therefore, the changing rig of designing high quality and low cost is extremely important.
In Anshan iron and steel plant 1780, during the straightener roll change, with two roll change framves is to fall within lower roll to fasten with the top roll of straightener or tensioner respectively, the relieving top chock is connected with hydraulic cylinder, closing the roll change frame, then roller system is directly pulled out from the frame of straightener or tensioner, wherein has following shortcoming:
1, during roll change by the direct pull-out roll of manpower system, not only waste time and energy, and dangerous;
2, in the process that roller system pulls out from straightener or tensioner, be sliding friction between bearing block and the roll change frame, wear extent, noise are all bigger.
The utility model content
Technical problem to be solved in the utility model provides a kind of changing machine, and it can realize the mechanization of roll change.
For solving the problems of the technologies described above, the technical solution of the utility model changing machine is:
Comprise the roll change frame, be provided with roll change buggy in the roll change track of roll change frame, described roll change frame is provided with sprocket wheel, and sprocket wheel is provided with chain; Sprocket wheel is connected with hand-rail type chain tooth roller box, and chain connects roll change buggy.
The roller system that described changing machine is changed comprises roller, step, and the bottom of described step is provided with rolling bearing.Described step is provided with lifting bolt.
The technique effect that the utility model can reach is:
The utility model roll change frame is provided with the chain that is connected with roll change buggy, and it is mobile on the roll change frame to drive roll change buggy by hand-rail type chain tooth roller box, by moving of roll change buggy, make roller system be moved out of frame, thereby realize the mechanization of roll change, changed the roller replacing mode that originally by the direct pull-out roll of manpower was, this roller replacing mode is simple, convenient, has reduced potential safety hazard.
The utility model is provided with rolling bearing in the step bottom of roller system, when mobile roller is, sliding friction between original step and the track is become rolling friction, frictional force in the time of can significantly reducing roll change between step and the track, the power of wear extent, noise, required use all can correspondingly reduce.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model changing machine;
Fig. 2 is the schematic diagram of step.
Among the figure, 1 roller, 2 roll change framves, 4 chains, 5 sprocket wheels, 6 hand-rail type chain tooth roller boxs, 7 lifting bolts, 11 rolling bearings, 12 steps.
The specific embodiment
As shown in Figure 1, the utility model changing machine comprises roll change frame 2, is provided with roll change buggy in the roll change track of roll change frame 2.Roll change frame 2 is provided with sprocket wheel 5, and sprocket wheel 5 is provided with chain 4; Sprocket wheel 5 is connected with hand-rail type chain tooth roller box 6, and chain 4 connects roll change buggy.
As shown in Figure 2, smoothing roll system (or jockey pulley system) comprises roller 1, step 12, and roller 1 is arranged on the step 12.The bottom of step 12 is provided with rolling bearing 11.Also be provided with lifting bolt 7 on the step 12.
During roll change, hand shaken hand-rail type chain tooth roller box 6 makes sprocket wheel 5 rotations, and the rotation of sprocket wheel 5 drives chain 4 and moves, and the moving belt of chain 4 is moved the roller dolly and moved.Make roll change buggy near smoothing roll system (or jockey pulley system), and hook the lifting bolt 7 of step 12.Mobile roll change buggy, roll change buggy drives smoothing roll system (or jockey pulley system) by lifting bolt 7 and moves, make smoothing roll system (or jockey pulley system) move to the roll change track of roll change frame 2, thereby smoothing roll system (or jockey pulley system) is shifted out frame from the roll change track of frame.
The smoothing roll that hangs away the wearing and tearing on the roll change frame 2 with driving is (or jockey pulley system), and new smoothing roll system (or jockey pulley system) is placed on the roll change track of roll change frame 2.Mobile roll change buggy moves to the roll change track of frame with new roller system from the roll change track of roll change frame 2, thereby new smoothing roll system (or jockey pulley system) is moved into frame, finishes the process of changing smoothing roll system (or jockey pulley system).
The utility model can be used for changing smoothing roll and the jockey pulley on the smooth unit of bundling, as Anshan iron and steel plant 1580 planishers; Also can be used for the straightener of various rolling units and the roller of tensioner.
