Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cutting equipment, in particular to a continuous casting billet cutting device. BACKGROUND

[0002] Continuous casting billet cutting is an important link in the continuous casting production process, the main purpose is to cut the continuous casting billet according to the predetermined length, so as to subsequent rolling or processing. The specific process flow is: molten steel continuously passes through the water-cooled crystallizer, coagulates into a hard shell, and then is continuously pulled out from the lower outlet of the crystallizer, and is cooled by water spraying. After complete solidification, it is cut into billets.

[0003] At present, the commonly used continuous casting billet cutting method is flame cutting. The flame cutting of metal is a process of metal combustion with oxygen. The role of fuel gas is to heat the metal to the ignition point by releasing heat through its own combustion. Because the temperature of continuous casting billet itself is relatively high, it does not need too much heat to heat the metal to the ignition point, so as to realize the cutting of the casting billet.

[0004] After searching, CN114570899B, a continuous casting billet cutting energy-saving type cutting device, is disclosed. The device includes an operating main body, which includes a placing seat, a cutting device is arranged on the top of the placing seat, a conveying frame is installed on the placing seat through the limiting block arranged on the top thereof, and a placing piece is arranged on the conveying frame.

[0005] Although the above-mentioned patent can realize the slitting of continuous casting billet, it still has the following shortcomings in actual application:

[0006] 1. Lack of follow-up cutting function: the above-mentioned patent needs to interrupt the conveying of continuous casting billet when cutting, which will interrupt the continuous feeding process of continuous casting billet. This intermittent feeding not only destroys the stability of continuous casting billet, but also may cause problems such as speed fluctuation and temperature unevenness. In addition, the frequent start and stop increases the response time of the equipment and the cutting waiting period, affecting the production rhythm and line efficiency.

[0007] 2. Lack of mechanism for correcting continuous casting billet: the continuous casting billet is pulled out at high temperature and then enters the conveying and cutting process. During the conveying process, it is easy to deviate, resulting in that the ideal straight posture cannot be maintained when entering the cutting station. The above-mentioned patent lacks the mechanism for correcting the continuous casting billet, so it cannot correct the posture of the continuous casting billet, resulting in problems such as inclined cutting surface, uneven cutting edge and length error, which affect the cutting precision of finished billet and subsequent processing and use.

[0036] Referring to Figures 1-2 The support mechanism comprises a rotating shaft 81, a chain wheel 82 and a chain 83, an opening 01 is formed in the top of the rack 1 between the two groups of motor rollers 2, the opening 01 is rotatably connected with two rotating shafts 81, the rotating shafts 81 are connected with two chain wheels 82 in front and back, the chain wheels 82 are sleeved with the chain 83 between the left and right two chain wheels 82, the chain 83 is located on the inner side of the gantry one 3, the chain 83 is connected with a connecting block 84 at intervals along its movement track, a support roller 85 is rotatably connected between the two connecting blocks 84 corresponding in front and back on the two chains 83, for supporting the continuously cast billet, when the support roller 85 rotates to the upper position, the top height of the support roller 85 is flush with the top of the gantry one 3 and the motor roller 2, and the three are in the same horizontal plane, so as to ensure the smooth transition of the continuously cast billet, the upper part of the two chains 83 is connected with a connecting block 86, and the connecting block 86 is connected to the inner top of the gantry one 3, two annular supporting plates 87 for supporting the support roller 85 are symmetrically connected in the opening 01, and the annular supporting plates 87 are located between the two chains 83.

[0037] Before cutting, first adjust the position of the visual detection module 15 according to the cutting length of the required blank. Control the forward rotation of the lead screw motor 16, which can drive the sliding block 13 to move the cross plate 14 to the left, thereby driving the visual detection module 15 to move leftward synchronously; control the reverse rotation of the lead screw motor 16, which can realize the right moving action of the sliding block 13 and the cross plate 14, and further drive the visual detection module 15 to adjust the position to the right, so as to meet the cutting requirements of blanks of different lengths. Through the electric roller 2, the continuous casting blank can be conveyed to the right, and at the same time, the visual detection module 15 is used to detect the continuous casting blank in real time, and the collected image information is transmitted to the background terminal for analysis and calculation. When the background terminal measures that the distance of the continuous casting blank moving to the right reaches the preset length, the background terminal sends a signal to the controller, which is not shown in the figure and is a prior art and will not be described here.

[0038] After the controller receives the signal, first control motor one 73 to drive screw 71 to rotate, thereby driving nut 72 to move gantry one 3 to the right, and make the moving speed of gantry one 3 consistent with the conveying speed of continuous casting blank, so as to ensure that gantry one 3 and its upper parts follow the movement of continuous casting blank synchronously. Then control motor two 96 to drive gear 97 to rotate, under the meshing action of gear 97 and rack 95, make the front and rear gears 97 close to each other, thereby making the front and rear sliders 93 close to each other, and further driving the front and rear push rods 94 to close to each other to push the continuous casting blank to move to the center and adjust, realize the automatic centering correction of continuous casting blank, make the continuous casting blank keep the ideal straight posture in the cutting station, ensure the flatness of the cutting surface, reduce the cutting error, and improve the cutting precision of the blank.

[0039] Then control the XY axis moving platform 5 to drive the flame cutting head 6 to move backward to cut the continuous casting billet by flame, when the next cutting cycle starts, the XY axis moving platform 5 drives the flame cutting head 6 to move forward to perform the next cutting operation. At the same time, before each cutting, the visual detection module 15 shoots the cutting seam between the two adjacent continuous casting billets and transmits the image information to the background terminal for analysis and calculation, and the controller controls the cutting according to the calculation result to ensure the consistency of the length of the continuous casting billet cut each time, further improving the cutting precision. Since the gantry 3 and the components thereon can follow the movement of the continuous casting billet and implement the cutting operation synchronously, the follow-up cutting function is realized, the cutting operation can be completed without interrupting the continuous conveying of the continuous casting billet, the continuous feeding of the continuous casting billet is effectively ensured, the stability of the feeding process is maintained, the stability of the continuous casting billet is avoided from being damaged due to frequent start and stop, the risks of speed fluctuation and temperature unevenness are significantly reduced, and the response time of the continuous casting equipment and the cutting waiting period are shortened, thereby improving the overall production rhythm and line operation efficiency.

[0040] When the gantry 3 moves to the right, the chain 83 is driven to rotate through the connecting block 86, so that the connecting block 84 drives the supporting roller 85 to rotate, so as to avoid the supporting roller 85 from hindering the movement of the gantry 3, and ensure the smooth movement of the gantry 3. At the same time, the supporting roller 85 can provide effective support for the continuous casting billet to ensure the stability of the continuous casting billet during conveying and cutting. After completing a cutting operation, first control the motor 96 to drive the gear 97 to reverse, so that the front and rear push rods 94 move away from each other to release the continuous casting billet, and at the same time, control the cylinder 91 to drive the guide rail 92 to move upward to release the continuous casting billet.
