Abstract

The utility model discloses a screw-down speed reducer for a rolling mill. The screw-down speed reducer comprises a first speed-reducing mechanism and a secondary speed-reducing mechanism, wherein the transmission shaft lines of the first speed-reducing mechanism and the secondary speed-reducing mechanism are arranged vertically; the first speed-reducing mechanism and the secondary speed-reducing mechanism can realize clutch speed-reducing control by a clutch; the structure of the first speed-reducing mechanism is that a motor is connected with a coupler, a clutch and a worm in sequence by the clutch, the worm is connected with a worm wheel, and the worm wheel is connected with a screw-down screw rod; the structure of the secondary speed-reducing mechanism is that a motor B is connected with a worm B by a coupler B, the worm B is connected with a worm wheel B by a clutch, the worm wheel B is connected with the worm, the worm is connected with the worm wheel, and the worm wheel is connected with a screw-down screw rod. With the arrangement of two sets of speed reducers, the reduction ratio range of the transmission is greatly enlarged, the different screw-down requirements of the hot rolling and the cold rolling, and the cost is lowered.

Description

A kind of milling train is depressed deceleration device

Technical field

The utility model belongs to the roll forming equipment technical field, relates to a kind of milling train and depresses deceleration device.

Background technology

Milling train is the visual plant that steel ingot or steel billet is rolled into steel, has the productivity ratio height, easily realizes advantages such as mechanization, automation.It uses more extensive than equipment such as forging and pressing, extruding, drawings.Smooth major function be improve plate shape and eliminate local thick poor, thereby make plate have good plate shape and surface quality preferably; Adopt little drafts can also eliminate the deep drawability that yield point elongation improves steel plate in addition.Existing its function ratio of rare metal milling train is more single, cold rolling, hot rolling, smoothly finished by different equipment, and individual other cold rollingly taken into account smooth function, for medium-sized and small enterprises,, need different equipment like this because different modes is rolling, the equipment purchasing cost burden increases the weight of, and maintenance cost increases.

Summary of the invention

The purpose of this utility model provides a kind of milling train and depresses deceleration device, makes a milling train can realize cold rolling, two kinds of functions of hot rolling, has reduced the equipment purchase cost.

The technical solution of the utility model is, a kind of milling train is depressed deceleration device, comprise first class reducer structure and two reduction gear, the orthogonal layout of transmission axis of first class reducer structure and two reduction gear, first class reducer structure and two reduction gear are realized the control that clutch is slowed down by clutch, and the structure of first class reducer structure is that motor is connected with shaft coupling, clutch, worm screw successively by clutch, worm and wheel connects, worm gear with depress leading screw and be connected; The structure of two reduction gear is, motor B is connected with worm screw B by shaft coupling B, and worm screw B is connected with worm gear B by clutch, and worm gear B is connected with worm screw again, the worm and wheel connection, worm gear with depress leading screw and be connected.

The beneficial effects of the utility model are, owing to be provided with the firsts and seconds deceleration device respectively, make the speed reducing ratio scope of transmission increase greatly, satisfy the hot and cold rolling different requirements of depressing, and are simple in structure, easy to maintenance, reduced equipment cost.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

With reference to Fig. 1, the structure that the utility model milling train is depressed deceleration device comprises first class reducer structure and the two reduction gear that is installed in the milling train top simultaneously, the first class reducer structure is distributed on the different horizontal planes with two reduction gear, the orthogonal layout of transmission axis of first class reducer structure and two reduction gear, first class reducer structure and two reduction gear are realized the control that clutch is slowed down by clutch 3, clutch 3 is provided with three stations, be respectively the hot rolling station, original state, cold rolling station, wherein the hot rolling station is implemented the one-level deceleration, and cold rolling station is implemented double reduction.

As shown in Figure 2, the structure of first class reducer structure is, motor 5 is connected with shaft coupling 10, clutch 3, worm screw 1 successively by clutch 3, and worm screw 1 is connected with worm gear 2, worm gear 2 with depress leading screw 11 and be connected.

As shown in Figure 3, the structure of two reduction gear is, motor B8 is connected with worm screw B6 by shaft coupling B7, and worm screw B6 passes through clutch 3 and is connected with worm gear B9, and worm gear B9 is connected with worm screw 1 again, and worm screw 1 is connected with worm gear 2, worm gear 2 with depress leading screw 11 and be connected.

During device work of the present utility model, when the needs hot rolling, because it is fast to require to depress speed, have only first class reducer structure participation work, the handle of clutch 3 is pulled one-level deceleration position, the pusher dog 4 of clutch 3 and shaft coupling 10 engagements, motor 5 drives worm screw 1 by shaft coupling 10, worm screw 1 drives worm gear 2, and worm gear 2 drives are depressed leading screw 11 and moved up and down, thereby reach fast speed rolling purpose.When cold rolling, it is slow with respect to hot rolling that general technology requires to depress speed, use two reduction gear, the handle of clutch 3 is pulled the double reduction position, the shaft coupling 10 of motor 5 drives of first class reducer structure is thrown off with worm screw 1 at this moment, the pusher dog 4 of clutch 3 and worm gear B9 engagement, at this moment starter motor B8, motor B8 drives worm screw B6 by shaft coupling B7, and worm screw B6 drives worm gear B9 by clutch 3 again, and worm gear B9 drives worm screw 1, worm screw 1 drives worm gear 2, worm gear 2 drives are depressed leading screw 11 and are depressed, and have realized double reduction, thereby have satisfied the speed of depressing of technological requirement.Owing to be provided with two cover deceleration devices, make the speed reducing ratio scope of transmission increase greatly, satisfy the hot and cold rolling different requirements of depressing.

The utility model milling train is depressed deceleration device to be contained on the milling train, can be suitable for four kinds of roller systems simultaneously---a cover two roller hot rolls system, a cover two roller cold rolls system, two covers, four roller cold rolls system, both can realize hot rolling, can realize cold rolling again, take into account smoothly, reduce equipment cost, improve usage ratio of equipment, rolling for the rare metal that yields poorly, for medium and small smelter particularly suitable.
