Background

In order to improve the yield of a steel rolling finished product workshop and better ensure the internal organization structure and the surface quality of a steel billet, a plurality of high-speed wire rod production lines, bar production lines and section steel production lines adopt large-sized continuous casting billets to automatically and repeatedly roll the continuous casting billets through a cogging mill with high rolling precision, large rolling moment and large compression ratio to obtain the optimal rolling billets required by the workshop. Then the steel is sent into a continuous rolling mill set or a universal mill set for continuous rolling so as to roll out the required wires, bars or section steel and the like.

The push bench is usually arranged at the front and rear entrance of the cogging mill, which is arranged above the run-in/run-out table. The push machine can automatically push the blank to the front of the corresponding pass according to the rolling pass and the pass of the cogging mill, position, straighten and turn the blank, and simultaneously, the push machine is matched with a working roller way of the cogging mill to accurately send the blank into the corresponding pass of the cogging mill to carry out reciprocating rolling.

As shown in FIG. 1, the cogging mill of this embodiment includes a roller table 10 for transporting billets and 2n push beds 100, where n is a natural number and n.gtoreq.1. The n push beds 100 are arranged on one side of the roller way 10 along the axial direction of the roller way 10, the other n push beds 100 are arranged on the other side of the roller way 10 along the axial direction of the roller way 10, the push beds 100 on two sides of the roller way 10 are oppositely arranged, and the push bed 100 on at least one side of the roller way 10 can move along the axial direction of the roller way 10. Preferably, n push tools 100 on one side of the roller way 10 correspond to n push tools 100 on the other side of the roller way 10 one by one, so as to form n pairs of push tools 100.

As shown in fig. 2 to 5, the manipulator 100 of the present embodiment may be disposed above the roller table 10, and may include a main body 1, a plurality of wear plates 2, and a plurality of edger mechanisms 3. Wherein, a plurality of wear plates 2 are distributed on the side of the main body 1 facing the billet along the long axis direction of the main body 1 (namely the feeding or discharging direction of the billet), and a plurality of vertical roll mechanisms 3 are also distributed on the main body 1 along the long axis direction of the main body 1. Any vertical roller mechanism 3 can comprise a frame 31, a vertical roller 32, an elastic piece, a bracket 34 fixedly connected with the main body 1, a first pin shaft 35 arranged on the frame 31 and a second pin shaft 36 arranged on the bracket 34.

The pusher 100 of the embodiment has at least two working states, in the first working state (the state of clamping the steel billet), the vertical rollers 32 are positioned between the wear plate 2 and the steel billet, that is, the vertical rollers 32 are in contact with the steel billet; in the second operating condition (the condition in which the billet is tapped), the wear plate 2 is located between the billet and the vertical rollers 32, i.e. the wear plate 2 is in contact with the billet.

Still alternatively, the manipulator 100 of the present embodiment may be disposed above the roller table 10, and may include a main body 1, a plurality of wear plates 2, and a plurality of vertical roller mechanisms 3. Wherein, a plurality of wear plates 2 are distributed on the side of the main body 1 facing the billet along the long axis direction of the main body 1 (namely the feeding or discharging direction of the billet), and a plurality of vertical roll mechanisms 3 are also distributed on the main body 1 along the long axis direction of the main body 1. Any vertical roller mechanism 3 comprises a frame 31, a vertical roller 32, an elastic member, a bracket 34, a first pin shaft 35 and a second pin shaft 36. The first pin shaft 35 is used for connecting the frame 31 and the vertical roller 32, and the vertical roller 32 can rotate around the first pin shaft 35; the elastic member is fixed on the main body 1, and the frame 31 abuts against one end of the elastic member, which is arranged towards the billet, so that the elastic member has a first compression state; the bracket 34 is fixed on the main body 1 and connected with the frame 31 through a second pin shaft 36, and the frame 31 can rotate around the second pin shaft 36 in the direction towards the elastic element so that the elastic element has a second compression state; the vertical rolls 32 are mounted on the frame 31 on the side of the frame 31 facing the billet. When the resilient member is in the first compressed state, the vertical rollers 32 project the wear plate 2 a first distance in a direction towards the steel blank; when the resilient member is in the second compressed state, the vertical rollers 32 project a second distance relative to the wear plate 2 in a direction towards the steel blank. The first distance may be between 8 and 10mm such that the edger roll 32 is located between the billet and the wear plate 2 and the second distance is less than or equal to 0mm such that the wear plate 2 is located between the edger roll 32 and the billet. Of course, the vertical roller 32 can rotate around the second pin shaft 36 in a direction away from the elastic member to restore the elastic member to the first compressed state.

With the above structure, the operating principle of the cogging mill using the pusher 100 of the present embodiment is: the first compression state of the elastic members of the pair of the push rams 100 may be adjusted according to the clamping force of the pair of the push rams 100 to the billet, so that the sum of the abutting forces (thrust forces) of the plurality of elastic members against the billet in the first compression state can be greater than or equal to the minimum clamping force required by the billet (when the billet is not inverted, the minimum clamping force of the pusher 100 against the billet) to ensure that in the clamping state, the billet is only in contact with the edging rolls 32 and not with the wear plate 2, so that, when the rolls 20 bite into the billet, because the plurality of vertical rollers 32 can rotate around the first pin shaft 35, rolling friction is generated between the billet and the pusher 100, and compared with sliding friction generated between the billet and the wear-resisting plate 2 in the prior art, rolling friction can reduce rolling force and energy consumption of the cogging mill, and rolling friction can also reduce scratches on the billet during rolling. When the pair of push beds 100 is used for tapping a steel billet, the push beds 100 impact the steel billet to generate a large impact force, and the impact force is larger than the abutting force of the push beds 100 to the steel billet, so that the elastic piece is compressed by the impact force and then retracts to be concave relative to the wear-resisting plate 2, so that the wear-resisting plate 2 can be in contact with the steel billet, and at the moment, the wear-resisting plate 2 bears the main tapping force to straighten the steel billet in the tapping process.

Compared with the mode of directly connecting the vertical roll 32 with the first pin shaft 35 in a contact manner, the vertical roll 32 and the first pin shaft 35 are connected by the bearing 37, so that friction force between the vertical roll 32 and the first pin shaft 35 during rotation can be avoided, further friction loss of the vertical roll 32 during rotation can be avoided, in addition, the bearing 37 can ensure the smoothness of rotation of the vertical roll 32, and further rolling friction force between the billet and the vertical roll 32 is reduced.
