A control method for hot delivery of precision forging blank

Abstract

The present application belongs to the technical field of billet forging production, and discloses a control method for hot conveying of fine and fast forging billets. After the continuous casting billet is in place, the billet is grabbed by the billet grabber and moved. After the billet is placed on the hot conveying billet sector roller mechanism, the hot conveying billet sector roller mechanism drives the billet to rotate by 90 degrees. After the rotation is in place, the billets are pushed into the conveying device one by one. The conveying device then conveys the billets to the first hot forging billet rotating mechanism. The first hot forging billet rotating mechanism then clamps the billets and turns them by 180 degrees. After the turning, the fast forging machine performs forging on the billets. After the forging, the second hot forging billet rotating mechanism clamps the billets and turns them by 180 degrees. Finally, the conveying device conveys the billets to the downstream. If the billet is not in place at any position, the alarm device is triggered to issue a warning. It can be seen that the present application realizes hot conveying of the billets, so that the entire hot conveying system can reliably operate. Once a problem occurs, a warning can be issued in a timely manner.

Once a problem occurs, a warning can be issued in time.

Once a false alarm occurs, the present application corrects the timer T1 according to the actual traveling speed of the billet grabber and the real-time position of the billet, and corrects the action time of each device downstream of the hot billet fan-shaped roller mechanism 1, so that the whole fast forging billet hot conveying system can continuously and efficiently operate.

[0103] The hot billet fan-shaped roller mechanism 1 used in the present application comprises a rotary seat and an arc-shaped guide rail, the rotary seat is rotationally connected with a rack, one side of the rack is provided with a translation chain row, the rack is provided with a roller group, the bottom of the rack is provided with a rotary wheel, and the side wall of the rack is provided with a rotary motor, and the output end of the rotary motor is connected with the rotary wheel. A first cold-hot metal detector or a first photoelectric switch can be arranged on the translation chain to detect whether the billet is in place. When the first cold-hot metal detector detects that the billet is placed in place, the rotary motor is started to make the hot billet fan-shaped roller mechanism 1 rotate by 90° with the billet, and whether the rotation is in place can be detected through the proximity switch arranged at the initial position of the conveying device 2. After the rotation is in place, the billet is pushed to the roller group, and the billet is sent to the conveying device 2 one by one by the roller group.

Once the false alarm occurs, the present application corrects the timer T2 according to the actual rotating speed of the first hot forging billet rotating mechanism 3 and the real-time position of the steel billet, and corrects the action time of the conveying device 2 and the downstream devices, so that the whole hot conveying system of the precision forging billet continuously and efficiently operates. The conveying device 2 used in the present application includes a roller motor, a roller speed reducer motor and a conveying roller, and a second cold-hot metal detector or a second photoelectric switch can be arranged on the conveying roller in the initial position to detect whether the steel billet is in place.

[0115] The timer T3 is set according to the conveying speed of the conveying device 2, and the false alarm caused by the conveying device 2 without conveying the steel billet to the first hot forging billet rotating mechanism 3 in the conveying process is eliminated by timing the timer T3. Once the false alarm occurs, the present application can correct the timer T3 according to the actual conveying speed of the conveying device 2 and the real-time position of the steel billet, and correct the action time of the first hot forging billet rotating mechanism 3 and the downstream devices, so that the whole hot conveying system of the precision forging billet continuously and efficiently operates.

[0122] The timer T4 is set according to the overturning speed of the first hot forging blank rotating mechanism 3. The timer T4 is used to count to exclude the false alarm caused by the fact that the first hot forging blank rotating mechanism 3 does not deliver the steel blank to the front of the fast forging machine 4 in the process of overturning the steel blank. Once the false alarm occurs, the timer T4 is corrected according to the actual overturning speed of the first hot forging blank rotating mechanism 3 and the real-time position of the steel blank.
