Description
Technical Field
The invention belongs to the field of equipment of a headless rolling strip steel production line, and particularly relates to a high-speed flying shear eccentric shearing structure for shearing thin strip steel.
Background
Steel plays an important role in production construction and daily life, and most of steel needs to be rolled to improve the mechanical property of the steel, so that the service performance is enhanced, and steel rolling equipment plays a great role.
The traditional flying shear is characterized in that: each shearing process involves a starting process, and the drum has only a 90-degree acceleration interval from the standby position to the shearing position, so that the speed which can be reached by the drum is limited. When the strip steel is cut, the speed of the overlapped part of the cutting edges is slightly higher than the running speed of the strip steel, and the strip steel can be cut. Therefore, the conventional flying shears are only suitable for the situation that the running speed of the strip is not high, such as the situation that the running speed of the strip does not exceed 1m/s before a finishing mill of a hot rolling strip production line, and the conventional flying shears are arranged at the place and are used for cutting the head and the tail of the intermediate billet or used for cutting the waste intermediate billet generated by accidents in a sectional way.
The endless rolling strip steel production line is a novel strip steel rolling technology, represents the highest level of the hot rolling strip steel production line in the current society, and can produce ultrathin strip steel to replace cold rolling. The continuous casting and rolling process is adopted in the endless rolling strip steel production line, the finished rolled strip steel needs to be subjected to fixed-length shearing before a coiling machine to complete coiling, so that a flying shear needs to be arranged at a position behind a finishing mill and before the coiling machine to complete shearing, but the running speed of the strip steel is very high and usually exceeds 10m/s, and particularly when ultrathin strip steel is produced, the speed can reach 15 m/s. Moreover, the shearing requirements are particularly stable here, since once the shearing process does not proceed smoothly here, it can affect the rolling of the upstream finishing mill and the coiling operation of the downstream coiler, and in severe cases even lead to the production stoppage of the whole production line. Obviously, the conventional flying shears cannot meet the use requirements. Therefore, a high-speed flying shear device which can meet the requirements of a headless rolling process and can stably and continuously shear ultrathin strip steel is urgently needed.

When the device works, the upper rotary drum 21 and the lower rotary drum 31 are driven to rotate by two transmission shafts of the transmission mechanism respectively, so that the speeds of the upper and lower shear blades are matched with the running speed of the strip steel, and the rotating speed is kept stable. At the beginning (non-shearing state), the unpowered input of eccentric drive arrangement, driving gear 42, eccentric gear 43, eccentric gear two 44 all are in quiescent condition, the round hole central line of eccentric gear one 43 is just above squinting this moment, the round hole central line of eccentric gear two 44 is just below squinting, install the last drum 21 and the lower drum 31 of going up in the round hole at this moment apart from the farthest, the centre-to-centre spacing is Y +2X, go up drum 21 and lower drum 31 and keep certain opening degree, go up shear blade 22 and lower shear blade 32 can not coincide at the rotatory in-process, can not sheared when belted steel passes through.
In a shearing state, the eccentric driving device 4 receives power input to enable the first eccentric gear 43 and the second eccentric gear 44 to rotate synchronously in opposite directions, at the moment, the center line of the circular hole of the first eccentric gear 43 moves downwards, the center line of the circular hole of the second eccentric gear 44 moves upwards, namely, the upper rotary drum 21 and the lower rotary drum 31 which are arranged in the circular holes respectively approach to each other, namely, the center distance is smaller and smaller, when the first eccentric gear 43 and the second eccentric gear 44 rotate 180 degrees, the upper rotary drum 21 and the lower rotary drum 31 reach the minimum center distance Y-2X, when the upper cutting edge 22 and the lower cutting edge 32 simultaneously rotate to reach a shearing position, the cutting edges are overlapped to shear strip steel, at the moment, the upper synchronous gear 23 on the transmission side and the lower synchronous gear 33 on the transmission side, the upper synchronous gear 24 on the operation side and the lower synchronous gear 34 on the operation side respectively reach a meshing state, so that the rotating speeds, the cutting effect and the cutting precision of the shear blade are greatly improved by synchronizing the rotating speed of the upper rotary drum and the rotating speed of the lower rotary drum.

At this time, the center distance between the upper rotary drum 21 and the lower rotary drum 31 is recovered to Y +2X, namely, the strip steel cannot be sheared by the upper and lower shearing blades in the rotating process, and the flying shear is recovered to a non-shearing state. At this time, a cutting process is completed, and when cutting is needed again, the eccentric driving device 4 is started.
The invention provides a high-speed flying shear structure for solving the problem that the traditional flying shear cannot shear high-speed running strip steel, wherein the upper rotary drum and the lower rotary drum are provided with power input during working, the stable rotating speed is always kept in the working process, the speed is ensured to be matched with the running speed of the strip steel, the rotary drums do not have frequent starting and braking conditions, the shearing action is completed by an eccentric driving device, and the switching between a shearing state and a non-shearing state is realized by adjusting the center distance of the upper rotary drum and the lower rotary drum. The driving device of the eccentric driving device is independent of the rotating transmission mechanism of the rotary drum, and the two sets of power equipment can be respectively and independently controlled, so that the whole structure is simple and easy to control.
The traditional flying shear starts the rotary drum every time of shearing, the rotation angle of the rotary drum in an acceleration interval is usually 90 degrees (the maximum is 270 degrees), so that the speed reached by the rotary drum is limited, the rotary drum stops rotating immediately after the shearing is finished, the rotary inertia of the rotary drum is large, the requirement on a main transmission device is high when the brake is started, and the speed of the rotary drum is not well controlled.
According to the high-speed flying shear provided by the invention, after the initial main transmission device is started, the rotating drum keeps stable rotating speed in work, the shearing does not need to be started and braked every time, the shearing is carried out by starting the eccentric driving device, and the eccentric driving device only takes charge of moving the position of the rotating drum and does not participate in the force supply during shearing.
The invention has simple structure, easy use and high stability, when in work, the upper and lower rotary drums have power input, the stable rotating speed is always kept and the speed is ensured to be matched with the running speed of the strip steel in the working process, the rotary drums have no frequent starting and braking conditions, the shearing action is completed by an eccentric driving device, and the switching between the shearing state and the non-shearing state can be realized by adjusting the center distance of the upper and lower rotary drums; the eccentric driving device is only responsible for moving the position of the rotary drum and does not participate in the force supply during shearing, so that the power of a transmission part of the eccentric driving device is small, the structure can be simple, the starting and braking are easy to control, the structural complexity and the cost of the eccentric driving device are favorably reduced, and the reliability of the flying shear structure is further improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
