Description
Technical field
The utility model relates to a kind of changing rig of metal plates and strips processing industry, particularly a kind of milling train.
Background technology
Milling train is in long-time processing metal strip material process, the surface of upper support roller, top working roll, bottom working roll and lower support roller will produce uneven wearing and tearing, even generation pit, cause the metal plates and strips poor surface smoothness that processes, do not reach required precision, in order to guarantee crudy, must process processing to the surface of upper support roller, top working roll, bottom working roll and lower support roller; The shaft coupling damage repair that next is connected with roll; Way at present commonly used is to adopt the hydraulic drive mode with upper support roller, top working roll, bottom working roll and lower support roller parallel shifting out in the milling train, carries out Surface Machining by modes such as last grinding machines again and handles.But aforesaid way has following weak point, with 3 meters milling trains is example, the gross weight that is moved reaches 180 tons, the distance that needs to move is 9 meters, promote at least 9 meters of oil cylinder and piston rod length, when practical application, can be subjected to the restriction of conditions such as cost, installing space position, floor space as hydraulic cylinder, because the restriction of these conditions, just need seek a kind of can satisfy the demands and new method, the new technology of condition solve the problems referred to above.
Summary of the invention
In order to overcome the shortcoming of above-mentioned existence, the purpose of this utility model provides a kind of simple and reasonable, use is easy to operate, cost is low, floor space is few mill roll device.
The technical scheme that its technical problem that solves the utility model adopts, it comprises the upper support roller, top working roll, bottom working roll, the lower support roller, frame, roll change track in the frame, roll change track and hydraulic power unit, promote oil cylinder, roller, roll change orbital docking in roll change track and the frame, roller cooperates with interior roll change track of frame and roll change track, described promotion oil cylinder is fixed on the cylinder support, the turnover oil pipe that promotes oil cylinder is connected with hydraulic power unit, the lower support roller is connected with dismountable long connecting rod by bearing pin, long connecting rod is connected with short connecting rod by dismountable attaching nut, and the other end of short connecting rod promotes on the oil cylinder piston bar by dismountable being connected of bearing pin.
The stroke of described promotion oil cylinder piston bar 9 is 2.6 meters.
The length of described long connecting rod is 4 meters.
The length of described short connecting rod is 2.5 meters.
After adopting said structure, the utility model has following advantage and effect: the one, can adopt 3 meters long promotion oil cylinder with long connecting rod, lack cooperating of connecting rod, finish the roll change work that 9 meters long promotion oil cylinders of original need just can be finished; The 2nd, simple in structure, input is economized, few, the maintenance and easy to maintenance of floor space, and equipment manufacturing cost can save 80%, takes up an area of length and can shorten 7 meters.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Shown in Figure 1, specific embodiments for the utility model mill roll device, it comprises upper support roller 1, top working roll 2, bottom working roll 3, lower support roller 4, frame 14, roll change track 13 in the frame, roll change track 15 and hydraulic power unit 11, promote oil cylinder 10, roller 16, roll change track 15 docks with roll change track 13 in the frame, roller 16 cooperates with interior roll change track 13 of frame and roll change track 15, described promotion oil cylinder 10 is fixed on the cylinder support 12, the turnover oil pipe that promotes oil cylinder 12 is connected with hydraulic power unit 11, lower support roller 4 is connected with dismountable long connecting rod 6 by bearing pin 5, long connecting rod 6 is connected with short connecting rod 8 by dismountable attaching nut 7, and the other end of short connecting rod 8 promotes on the oil cylinder piston bar 9 by bearing pin 5 dismountable being connected.The stroke of described promotion oil cylinder piston bar 9 is 2.6 meters; The length of described long connecting rod 6 is 4 meters; The length of described short connecting rod 8 is 2.5 meters.
Be that example further specifies operation principle of the present utility model with 3 meters milling trains below, start hydraulic power unit 11, stretch out promotion oil cylinder piston bar 9, connect short connecting rod 8, connect long connecting rod 6 again, be connected with the lower support roller 4 that is moved at last; Withdrawal promotes oil cylinder piston bar 9, and at this moment upper support roller 1, top working roll 2, bottom working roll 3, lower support roller 4 are moved 2.6 meters of distances simultaneously.Remove short connecting rod 8, stretch out and promote oil cylinder piston bar 9 and be connected, the promotion oil cylinder piston bar 9 of withdrawing, at this moment upper support roller 1, top working roll 2, bottom working roll 3, lower support roller 4 2.6 meters of displacements once more with long connecting rod 6.Remove long connecting rod 6, stretch out promotion oil cylinder piston bar 9 and be connected with short connecting rod 8, connect the 4 back withdrawals of lower support roller again and promote oil cylinder piston bars 9, at this moment upper support roller 1, top working roll 2, bottom working roll 3, lower support roller 4 are mobile 2.6 meters for the third time.Remove short connecting rod 8, this is connected the back withdrawal with the lower support roller to stretch out promotion oil cylinder piston bar 9, so far finishes for the third time and moves 2.6 meters, thereby finish ten meters displacements.When need are moved the part return-to-home position, only need to get final product by opposite procedure operation.
