Description
Technical field
The utility model relates to the adjustment of a kind of rolling miller equipment, particularly a kind of rolling mill screwdown adjuster.
Background technology
Shaped steel memorial archway milling train adopts Electro-pressing usually, along with each steel mill is in recent years to the deep level development of product, the blooming mill of some steel mill directly goes out finished steel, in order to improve Product Precision, require more and more higher to the Adjustment precision of blooming mill, usual blooming mill pressure only has one or two powerful motor to realize the rapid adjustment of roll gap, if need accurate adjustment can only be that operative employee adjusts with spanner.Also having a kind of is exactly increase a set of reducer with big speed ratio motor to realize accurate adjustment when pressure design, as shown in Fig. 1.
Artificial accurate adjustment pressure is in the on-the-spot more common method of adjustment of Section Steel Production, normally operator overlaps extension bar with spanner on milling train fore side or pressure platform, that requires great effort very much adjusts screw down mechanism of rolling mill, realizes adjustment by observing the change of pressure pointer.
Another is exactly to realize the quick pressure of pressing speed and accurate adjustment is whole at a slow speed by two cover transmission systems, power of motor as " Fig. 1 " left side depresses motor more fast, before the small machine on right side, planetary reducer is housed to be used for realizing accurate adjustment at a slow speed, this scheme requires higher to Automated condtrol, and new design production line can adopt this structure.This screw-down is depressed at a slow speed on right side between worm-gear speed reducer machine and an arrangement of clutch is housed, arrangement of clutch similar between arrangement of clutch and two pressure worm-gear speed reducers, clutch when working at ordinary times at a slow speed before screwdown gear is in open mode, and the heavy motor in left side can realize the rapid adjustment of Long Distances with dynamic compressor screw mandrel like this.Arrangement of clutch before adjusting at a slow speed reductor on the right side of in time needing accurate adjustment at a slow speed closes, and the small machine on right side drives the work of pressure worm-gear speed reducer to realize the fine setting up and down of screw mandrel by reductor.
It is large to there is labour intensity in artificial accurate adjustment rolling mill screwdown, the shortcomings such as Adjustment precision is poor, and speed is slow; This Dual Drive version of two cover transmission systems, invests higher, requires high, require high, be usually only applicable to grassroot project to operative employee automated system.
Utility model content
The purpose of this utility model is to provide a kind of rolling mill screwdown adjuster, and to overcome the deficiency that prior art exists, the utility model is simple for structure, reliable in action, trouble point is few, controls is simple, easy working service.
For achieving the above object, the utility model adopts following technical scheme:
A kind of rolling mill screwdown adjuster, comprise the worm shaft be connected with reductor rotating mechanism, described worm shaft is provided with swing arm, ratchet and end cap from inside to outside successively; Swing arm is provided with the ratchet that can coordinate with ratchet, and swing arm has oil cylinder by pinned connection.
Further, self-lubricating copper sheathing is provided with between described swing arm and worm shaft.
Further, described ratchet is connected by key with worm shaft.
Further, ratchet is provided with spring, the other end of spring is fixed in swing arm.
Further, swing arm is provided with for the spacing block of ratchet.
Compared with prior art, the utility model has following useful technique effect:
The utility model utilizes hydraulic oil cylinder driving ratchet, worm shaft is driven to realize pressure accurate adjustment, hydraulic oil cylinder driving easily realizes controlling, the working strength of operative employee can be reduced, the utility model utilizes that ratchet driving structure is succinct, reliable in action, trouble point is few, controls is simple, easy working service, grassroot project equipment cost can be reduced, also can be applied to the projects such as old production line pressure transformation.

Wherein, 1, end cap; 2, ratchet; 3, key; 4, swing arm; 5, self-lubricating copper sheathing; 6, worm shaft; 7, spring; 8, ratchet; 9, oil cylinder; 10, block.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 2,3, 4, a kind of rolling mill screwdown adjuster of the utility model, comprise the worm shaft 6 be connected with reductor rotating mechanism, worm shaft 6 is provided with swing arm 4, ratchet 2 and end cap 1 from inside to outside successively, be provided with self-lubricating copper sheathing 5 between swing arm 4 and worm shaft 6, ratchet 2 is connected by key 3 with worm shaft 6; Swing arm 4 is provided with the ratchet 8 that can rotate, and ratchet 8 is provided with spring 7, and the other end of spring 7 is fixed in swing arm 4, swing arm 4 is provided with for the spacing block 10 of ratchet 8, during work, hand rotation ratchet 8 is to ratchet 2 working position, and after completing adjustment, hand rotation ratchet 8 opens position to block 10; Swing arm 4 has oil cylinder 9 by pinned connection.
Below in conjunction with accompanying drawing, structural principle of the present utility model and use step are described further:
Ratchet 8 contacts with block 10 under the active force of spring 7, is in and opens position, if now rapid adjustment pressure, then ratchet 2 dallies along with worm shaft 6, and swing arm 4 is equipped with self-lubricating copper sheathing 5 so keep original position due to endoporus.If need screw mandrel to finely tune downwards in due to situations such as roll wears, at this moment need manually to move ratchet 8 to working position, ratchet 8 contacts with ratchet 2 under the active force of spring 7, oil cylinder 9 piston rod stretches out and drives swing arm 4 to rotate, ratchet 8 in swing arm 4 drives ratchet 2 to rotate, ratchet 2 drives worm shaft 6 to rotate together, the micro-accurate adjustment realizing pressure (needs according to concrete worm reduction gear speed ratio during design, the pitch of down screw rod, down screw rod Adjustment precision, about 0.05-0.1mm obtains the rotational angle of worm screw, thus draw the stroke of oil cylinder, so each adjustment amount is relatively fixing), if the adjustment amount that oil cylinder one stretches out circulation of retracting can carry out several circulation not continuously, thus the adjustment realized compared with heavy reduction, adjust rear needs manually ratchet to be pushed and open position, the accurate adjustment of pressure terminates.
