[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figures 1 to 5 A slab cutting and marking machine comprises: a transport roller 1, the transport roller 1 is used to transport the slab 101, a cutting part and a marking part are sequentially arranged along the transport direction of the transport roller 1, the cutting part comprises a cutting frame 2 installed above the transport roller 1, and a flame cutting gun 401 which can slide back and forth is provided on the cutting frame 2, wherein the cutting direction of the flame cutting gun 401 is arranged perpendicular to the transport direction of the transport roller 1, and the flame cutting gun 401 is used to cut the slab 101, and the marking part comprises a marking device 6 slidably connected to the transport roller 1, wherein, when the cutting part cuts the slab 101, the moving speed of the cutting frame 2 is synchronized with the transport speed of the transport roller 1, and in the process of the cutting part cutting the slab 101, the marking device 6 completes marking on the side wall of the slab 101.

[0023] When the transport roller 1 transports the slab 101 through the cutting frame 2, a length detection sensor is set on the cutting frame 2. As the slab 101 moves, the length detection sensor detects the length of the slab 101. When it reaches the distance required for cutting, it feeds back to the computer controller to control the synchronous movement of the cutting frame 2, so that the cutting frame 2 and the slab 101 are relatively stationary, and at the same time, the flame cutting gun 401 in the cutting part is started to cut.

[0024] Among them, when the flame cutting gun 401 slides on the cutting frame 2, the nozzle 6 is started synchronously and moves toward the side wall of the slab 101 to work. Before the flame cutting gun 401 completes cutting, the nozzle 6 completes the nozzle work and resets. Position sensors are set at both ends of the cutting frame 2 to detect the position of the flame cutting gun 401. After the flame cutting gun 401 completes cutting, the position sensor feeds back the detected position to the computer controller. At this time, the cutting frame 2 and the flame cutting gun 401 are reset, and the cut slab 101 is transported to the downward process by the transport roller 1. The cutting frame 2 and the flame cutting gun 401 reset to the initial position are ready to cut the next slab 101.

[0025] The cutting section also includes a reciprocating screw rod 201 rotatably connected to the cutting frame 2 and a drive motor 202 fixedly connected to the cutting frame 2. The reciprocating screw rod 201 extends along the width direction of the slab 101 (perpendicular to the transport direction of the slab 101) and has a certain length. The reciprocating screw rod 201 is fixedly connected to the output end of the drive motor 202 so that it can be driven by the drive motor 202 to rotate. A screw rod seat 4 is threadedly connected to the reciprocating screw rod 201. The screw rod seat 4 is stepped as the reciprocating screw rod 201 rotates. The flame cutting gun 401 is fixedly connected to the flame cutting gun 401 so as to move along with the screw rod.

[0026] Specifically, the computer controller controls the start and stop of the drive motor 202. When the drive motor 202 is working, the reciprocating screw 201 is driven to rotate through the coupling, so that the screw seat 4 and the flame cutting gun 401 can slide back and forth on the cutting frame 2 to achieve cutting of the plate blank 101.

[0027] It should be noted that, in another embodiment, the sliding of the flame cutting gun 401 can also be controlled by a telescopic rod, such as electrically or hydraulically, and the control part of the telescopic rod is controlled by a computer controller.

[0028] The side of the transport roller 1 is fixedly connected to a support frame 7, and the spray gun 6 is slidably connected to the support frame 7 through a dovetail groove and a dovetail block. It should be noted that a buffer is provided at the end of the spray gun 6 close to the slab 101 to prevent the spray gun 6 from directly contacting and being damaged by the slab 101.

[0029] An electromagnet 701 is fixedly connected to the support frame 7, a magnet 702 is fixedly connected to the nozzle 6, a push spring 703 is fixedly connected to the bottom of the nozzle 6, and the other end of the push spring 703 is fixedly connected to the transport roller 1, wherein the cutting frame 2 is provided with a control unit for controlling the power on and off of the electromagnet 701. When the electromagnet 701 is energized, the electromagnet 701 and the magnet 702 magnetically repel each other, and the repulsive force generated by the magnetic repulsion causes the nozzle 6 to slide toward the side wall of the slab 101;

[0030] Specifically, when the cutting part is working, the electromagnet 701 is energized and has magnetism. Under the action of magnetic repulsion, the sprayer 6 slides toward the plate blank 101. After being buffered by the buffer, the sprayer 6 slides to the maximum distance. At this time, the sprayer 6 sprays the number along the side wall to be sprayed;

[0031] After the number is sprayed and before the cutting part completes the cutting, the electromagnet 701 is powered off. At this time, the magnet part 702 is not affected by the magnetic force. Under the action of the push spring 703, the magnet part 702 and the number sprayer 6 are reset to the initial position. At this time, the cutting part completes the cutting synchronously.

[0032] The control unit includes a lower wire 5 and an upper wire 501 connected to the positive and negative poles of the power supply; a sliding shaft 402 is slidably connected to the screw seat 4, a conductive block 403 is fixedly connected to the sliding shaft 402, a spring member 404 is sleeved on the sliding shaft 402, and the two ends of the spring member 404 are respectively connected to the screw seat 4 and the conductive block 403, and the lower wire 5 is fixedly connected to the conductive block 403; a conductive shaft 502 is fixedly connected to the cutting frame 2, and the upper wire 501 is fixedly connected to the conductive shaft 502. When the conductive shaft 502 contacts the conductive block 403, the circuit of the control electromagnet 701 is connected;

[0033] Specifically, when the control unit controls the magnetic force of the electromagnet 701, it refers to Figure 3 The two ends of the conductive shaft 502 are bent, and the length of the straight portion of the conductive shaft 502 is less than the width of the plate blank 101, so that the flame cutting gun 401 on the screw seat 4 cuts first, and after cutting, the conductive block 403 on the screw seat 4 is connected to the conductive shaft 502 to provide magnetic force for powering the electromagnet 701;

[0034] Accordingly, before the cutting is completed, the electromagnet 701 is also powered off;

[0035] It should be noted that when the telescopic rod is used, the conductive block 403 and the sliding shaft 402 are arranged on the mounting seat of the flame cutting gun 401 .

[0036] An electric telescopic rod 3 is fixedly connected to the cutting frame 2, and a connecting piece 302 is fixedly connected to the output end of the electric telescopic rod 3. The electric telescopic rod 3 is connected to a coating piece 301 through the connecting piece 302, which is used to coat the position to be sprayed to facilitate the spraying of the sprayer 6.

[0037] Compared with the slab cutting and slab numbering that were carried out independently in the past, the utility model can simultaneously carry out slab numbering during the slab cutting operation through the cutting part and the numbering part, thereby reducing the overall operation time of slab cutting and slab numbering in the continuous casting link and improving work efficiency.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
