Technical Field
The invention belongs to the technical field of cold control in steel rolling production, and particularly relates to a front spray cooling device and method for a liftable cold shears.
Background
With the investment of technologies based on the apron plate steel feeding system tail braking device, the cooling bed automatic single-partition groove material distribution function and the like, the rolling speed is improved, and the machine hour yield is increased. However, "increase production and enable" does not expand the capacity of cooling control equipment such as a cooling bed, which leads to the reduction of the cooling time of steel, so that the temperature of the bar can not reach the required lower range during shearing, the bar is transported by a four-link steel supporting mechanism such as wheatstone, after the shearing of a cold shearing machine, the steel head can have the situations of 'elbow steel', 'blackhead steel' and 'blue head steel', and the problems that a counter of the next procedure cannot identify and count incorrectly can be caused, a large amount of returned work materials are generated, or the bar is judged to be waste due to the quality defect caused by the elbow.
CN211249353U discloses a front spray cooling device of a cold shearing machine, which uses high-pressure gas to push cooling water to perform concentrated spray cooling on the shearing position of steel. Although the problem that the temperature of the shearing position of the rod material is high can be solved in the prior art in principle, the transition mechanism from the cooling bed to the cold shear of the rod material is mostly a four-bar lifting mechanism, the device can only be fixed at a position higher than the lifting mechanism, the shearing position is sprayed and cooled from the high position, the spraying position is large, the spraying path is long and the like, the full cooling of the rod material is not facilitated, and the quality defect and reworking material problem caused by insufficient cooling still exist.
The invention aims to provide a bar cutting and cooling device which is characterized in that a spray cooling system can be automatically lifted, so that the effective, accurate and high-pressure cooling effect in a short time is realized, the shearing waste of finished steel products is reduced, and the yield of the steel products is improved.
Disclosure of Invention
The invention aims to provide a bar cutting device, which solves the problems that in the spraying and cooling process, the spraying distance is too long, so that the spraying position is too large, and the temperature is not sufficiently reduced. According to the invention, the power driving device is arranged on the spray rack, so that the technical effects of automatic lifting of the spray rack and efficient cooling of the bar are realized.
The invention relates to a bar cutting and cooling device which is characterized by comprising a steel supporting system, a spraying and cooling system and a cutting system.
The steel supporting system is a four-bar mechanism or a Wheatstone system and is used for transporting the bar to the spray cooling system, the spray cooling system carries out spray cooling on the part to be sheared of the bar, and after cooling, the bar is transported to the cutting system for shearing.
It should be noted that after the bar material is cooled by the cooling bed, the four-bar linkage mechanism or wheatstone will support a certain amount of bar material to the front shearing roller, and the spray cooling system sprays and cools the sheared part before the front shearing roller is dynamically transported to the cutting system.
Furthermore, the spray cooling system comprises a rack mounting plate provided with a spur rack, and the spur rack is meshed with a gear coupling in the brake motor to drive the rack mounting plate to move up and down; and the top end and the bottom end of the straight rack are respectively provided with a limit switch, and the limit switches limit the maximum lifting stroke of the rack mounting plate.
Further, the rack mounting plate is provided with a through hole for fixedly mounting a spray rack, and the spray rack is communicated with a water supply system for controlling spray water through a flexible connecting pipe.
Furthermore, the rack mounting plate drives the spray rack to move up and down along the straight rack under the braking action of the brake motor, and the limit switch group limits the maximum stroke of the rack mounting plate.
It should be noted that, in order to avoid potential safety hazards caused by resource waste and too high center of gravity due to the fact that the spray frame rises too high, and avoid losses caused by the fact that the spray frame falls too low and collides with a bar or other devices, the limit switch group limits the rising and falling paths of the spray frame, so that the spray frame only moves within a safety range, the use safety of the device is guaranteed, and the loss risk of the device is reduced.
It should be further explained that, before the wheatstone mechanism carries the bar to the roller way before the cold shears, in order to not hinder the smooth completion of the steel supporting process, the spraying frame is in a high position standby state under the braking action of the brake motor, namely, higher than the highest position of the lifting mechanism, and after the bar is positioned, the wheatstone stops and then gives a signal to prompt the brake motor to start. When the brake motor works, the gear coupling in the brake motor rotates and drives the straight rack meshed with the gear coupling, the rack mounting plate and the spraying frame move synchronously, the spraying frame descends, after the spraying frame is lowered to the optimal spraying position at the upper end of the shearing part of the bar, namely the position of the bottom limit switch, the brake motor stops, the shearing part is sprayed at high pressure by using a water supply system, and the spraying of the shearing part is only realized.
