Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 The utility model provides a technical solution: a continuous casting billet cutting device, comprising a first linear drive module 1, a second linear drive module 2, a cutting mechanism 4 and a guide roller group 6, the first linear drive module 1 and the second linear drive module 2 are connected by a first connecting plate 3, the second linear drive module 2 and the cutting mechanism 4 are connected by a second connecting plate 5, the cutting mechanism 4 comprises a base plate 41, a mounting frame 42, a three-axis cylinder 43, a drive plate 44, a drive slide 45 and a flame cutting head 46, a continuous casting billet 7 is placed on the guide roller group 6, and the guide roller group 6 can drive the continuous casting billet 7 on its upper portion to feed at a uniform speed.

[0024] Among them, the flame cutting head 46 uses a gas flame to heat the surface of the continuous casting billet 7 so that it reaches the combustion temperature locally, and then introduces a high-purity, high-speed cutting oxygen flow to cause the metal to undergo a violent combustion reaction and release heat. At the same time, with the help of the huge kinetic energy of the high-speed cutting oxygen flow, the combustion products are blown away and a cutting seam is formed to cut the continuous casting billet 7.

[0025] Among them, the first linear drive module 1 can drive the cutting mechanism 4 to move linearly along the Y-axis direction, and the second linear drive module 2 can drive the cutting mechanism 4 to move linearly along the X-axis direction. The cutting direction of the cutting mechanism 4 can be flexibly adjusted through the first linear drive module 1 and the second linear drive module 2.

[0026] Among them, the cutting mechanism 4 includes three groups of flame cutting heads 46, which form three groups of cutting positions. When performing the cutting operation, a section of continuous casting billet 7 can be cut into multiple sections of fixed-length continuous casting billets at one time, thereby improving the cutting efficiency of the continuous casting billets.

[0027] Among them, the base plate 41 is welded and fixed to the mounting frame 42, and the three-axis cylinder 43 is installed on the top of the mounting frame 42. The three-axis cylinder 43 includes a push rod, and one end of the push rod is fixedly connected to the driving plate 44. Three groups of driving slides 45 are slidingly set at the lower end of the driving plate 44. The three groups of driving slides 45 are fixedly provided with a flame cutting head 46. When the three-axis cylinder 43 is working, it drives the driving plate 44 at its lower end to move axially.

[0028] Among them, a guide groove 411 is opened on the base plate 41, and there are three groups of guide grooves 411. The guide grooves 411 on both sides are symmetrically arranged with respect to the guide groove 411 in the middle position. A guide shaft 451 is welded and fixed to the rear end of the driving slide 45, and the guide shaft 451 is slidably connected to the guide groove 411, and the driving slide 45 is slidably connected to the base plate 41.

[0029] A slide bar 441 is provided on the lower end surface of the driving plate 44 . The slide bar 441 is slidably connected to the driving slide 45 , and the driving slide 45 is slidably connected to the driving plate 44 .

[0030] Among them, the base plate 41, the mounting frame 42, the three-axis cylinder 43, the drive plate 44 and the drive slide 45 constitute a pitch-changing mechanism. When the three-axis cylinder 43 is working, its push rod drives the drive plate 44 to move axially, and the drive plate 44 drives the three groups of drive slides 45 below it to move, so that the top of the drive slide 45 slides along the slide bar 441, and the guide shaft 451 at the rear end of the drive slide 45 slides along the guide groove 411, thereby synchronously adjusting the spacing between the three groups of flame cutting heads 46. The spacing is controlled by the telescopic stroke of the three-axis cylinder 43.

[0031] The spacing between the three groups of flame cutting heads 46 is the length of the cutting fixed length. Multiple groups of cutting positions can cut into multiple sections of fixed-length continuous casting billets at one time, and the length of the fixed length is flexibly adjustable to meet different cutting requirements.

[0032] The flame cutting head 46 is connected to the cutting torch assembly and performs cutting using a gas flame.

[0033] Among them, the first linear drive module 1 and the second linear drive module 2 both include a U-shaped base 11, and a motor 12 is fixedly arranged on one side surface of the U-shaped base 11. The output shaft of the motor 12 is fixedly connected to the screw rod 13 through a coupling, and sliding rods 14 are arranged on both sides of the screw rod 13. A slide 15 is provided on the slide rod 14 and the screw rod 13.

[0034] When the motor 12 is working, it drives the screw rod 13 to rotate, causing the slide 15 to slide along the axis direction of the slide rod 14 to achieve linear drive.

[0035] One end of the first connecting plate 3 is fixed to the slide 15 of the first linear drive module 1 .

[0036] Among them, the other end of the first connecting plate 3 is fixed between the U-shaped base 11 of the second linear drive module 2. The second linear drive module 2 is located at the upper end of the first linear drive module 1 and is fixed between the slide 15 of the first linear drive module 1. The second linear drive module 2 is driven to move by the slide 15 of the first linear drive module 1.

[0037] Among them, one end of the second connecting plate 5 is fixed to the slide 15 of the second linear drive module 2, and the other end of the second connecting plate 5 is fixed to the mounting bracket 42 of the cutting mechanism 4, and the cutting mechanism 4 is driven to move by the slide 15 of the second linear drive module 2.

[0038] Working principle: When in use, the flame cutting head 46 is connected to the cutting torch assembly, and the guide roller group 6 drives the continuous casting billet 7 on its upper part to feed at a uniform speed and move to the cutting area. According to the cutting requirements, the spacing between the three groups of flame cutting heads 46 is pre-adjusted by the pitch changing mechanism. When the continuous casting billet 7 moves to the specified position, the cutting direction of the flame cutting head 46 of the cutting mechanism 4 is flexibly adjusted by the first linear drive module 1 and the second linear drive module 2. The continuous casting billet 7 is cut by the flame cutting head 46. The three groups of flame cutting heads 46 form three groups of cutting positions, which can cut a section of continuous casting billet 7 into multiple sections of fixed-length continuous casting billets at one time, and reset after cutting is completed.
