Description

Technical Field

[0001] This invention relates to the field of continuous casting processing technology, and in particular to a hydraulic shear for steel billets in a continuous casting machine. Background Technology

[0002] A continuous casting machine is a piece of equipment used in steel production, primarily for continuously casting molten steel into solid billets. The continuous casting machine works by pouring high-temperature molten steel from a ladle into a tundish, and then injecting it into a crystallizer through a submerged entry nozzle. The molten steel cools in the crystallizer, forming a billet shell, which is then pulled out by a billet puller. After further cooling and solidification in a secondary cooling zone, a continuous billet is finally formed. During processing, hydraulic shears are used to cut the billets. Existing hydraulic shears for continuous casting machines can generally meet daily usage needs. However, without fixing the billet during the cutting process, the shears are prone to shifting, affecting cutting accuracy. Furthermore, the clamping mechanism requires adjustments to its position based on different billet sizes, impacting the practicality of the hydraulic shears. Additionally, most existing hydraulic shears are fixed to the continuous casting machine, requiring a single arrangement for different cutting needs, thus affecting the processing efficiency of the continuous casting machine. Therefore, designing a hydraulic shear for continuous casting machine billets is essential. Summary of the Invention

[0003] The purpose of this invention is to provide a hydraulic shear for continuous casting machine billets to overcome the shortcomings of existing methods.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a hydraulic shear for steel billets of a continuous casting machine, comprising a main support, an auxiliary clamping mechanism, a spacing adjustment mechanism, a shearing arm, and a hydraulic cylinder. The main support has symmetrically arranged lifting cylinders in the auxiliary clamping mechanism on both sides. A connecting frame is fixedly installed at the output end of the lifting cylinder. A guide shell is provided at the bottom of the connecting frame, and a telescopic arm is slidably connected in the guide shell. A toothed groove on the inner wall of the telescopic arm meshes with a telescopic gear. A first cylinder is fixedly installed on one side of the connecting frame, and a second cylinder is fixedly installed on the telescopic arm. Clamping blocks are fixedly connected to the output ends of both the first and second cylinders. Adjusting sleeves in the spacing adjustment mechanism are rotatably connected in symmetrically arranged through holes on the main support. The adjusting sleeves are connected to the adjusting screw through internally embedded ball nuts. An adjusting roller is fixedly sleeved on the adjusting sleeve, and a transmission belt is wound around the adjusting roller, which is wound around the output roller.

[0005] As a further technical solution of the present invention, the auxiliary clamping mechanism consists of a lifting cylinder, a connecting frame, a guide shell, a telescopic arm, a telescopic gear, a gear motor, a first cylinder, a second cylinder, and a clamping block, with the telescopic gear fixed on the output end of the gear motor.

[0006] As a further technical solution of the present invention, the gear motor is fixedly mounted on the guide shell.

[0007] As a further technical solution of the present invention, the spacing adjustment mechanism consists of an adjustment sleeve, an adjustment roller, a transmission belt, an adjustment screw, an output roller, an output shaft, an output motor, and a fixed frame, with both ends of the adjustment screw fixed on the fixed frame.

[0008] As a further technical solution of the present invention, the output roller is fixedly sleeved on the output shaft, the output shaft is fixed on the output end of the output motor, and the output motor is fixedly installed on the top of the main bracket.

[0009] As a further technical solution of the present invention, a shearing arm is rotatably connected to the main support, and one side of the shearing arm is rotatably connected to the output end of the hydraulic cylinder.

[0010] As a further technical solution of the present invention, the hydraulic cylinder is rotatably connected in the main support.

[0011] The present invention provides a hydraulic shear for steel billets in a continuous casting machine. Its advantages include: the main support is supported by a fixed frame and an adjusting screw. An adjusting sleeve rotatably connected to the main support is connected to the adjusting screw via an internally embedded ball nut, forming a sliding connection structure for the main support. An output motor drives the output shaft to rotate, which in turn drives the adjusting rollers and adjusting sleeve to rotate via the output rollers and transmission belt, allowing the main support to slide between the fixed frames. Multiple fixed frames can be arranged to simultaneously shear a section of steel billet, and the spacing between the main supports can be easily adjusted as needed, improving the processing efficiency of the continuous casting machine. A guide shell slides to support the telescopic arm, forming a ring-shaped clamping structure. Before shearing, a lifting cylinder moves the connecting frame up and down, adjusting the clamping center height of the ring-shaped clamping structure. During shearing, a first cylinder and symmetrically distributed second cylinders drive the clamping blocks to synchronously approach and fix the steel billet, ensuring shearing accuracy while adapting to different sizes of steel billets without manual adjustment, thus improving the practicality of the device.

[0020] Please see the appendix Figure 1 -Appendix Figure 5One embodiment of the present invention provides a hydraulic shear for a continuous casting machine billet, comprising a main support 1, an auxiliary clamping mechanism 2, a spacing adjustment mechanism 3, a shearing arm 4, and a hydraulic cylinder 5. Lifting cylinders 21 of the auxiliary clamping mechanism 2 are symmetrically arranged on both sides of the main support 1. A connecting frame 22 is fixedly installed at the output end of the lifting cylinder 21. A guide shell 23 is provided at the bottom of the connecting frame 22, and a telescopic arm 24 is slidably connected in the guide shell 23. A toothed groove on the inner wall of the telescopic arm 24 meshes with a telescopic gear 25. A hydraulic shear is fixedly installed on one side of the connecting frame 22. A first cylinder 27 is installed, and a second cylinder 28 is fixedly installed on the telescopic arm 24. Clamping blocks 29 are fixedly connected to the output ends of both the first cylinder 27 and the second cylinder 28. An adjusting sleeve 31 from the spacing adjustment mechanism 3 is rotatably connected to symmetrically opened through holes on the main support 1. The adjusting sleeve 31 is connected to the adjusting screw 34 via an internally embedded ball nut. An adjusting roller 32 is fixedly sleeved on the adjusting sleeve 31, and a transmission belt 33 is wound around the adjusting roller 32. The transmission belt 33 is wound around the output roller 35. (Auxiliary...) The clamping mechanism 2 consists of a lifting cylinder 21, a connecting frame 22, a guide shell 23, a telescopic arm 24, a telescopic gear 25, a gear motor 26, a first cylinder 27, a second cylinder 28, and a clamping block 29. The telescopic gear 25 is fixed to the output end of the gear motor 26; the gear motor 26 is fixedly mounted on the guide shell 23. The spacing adjustment mechanism 3 consists of an adjusting sleeve 31, an adjusting roller 32, a transmission belt 33, an adjusting screw 34, an output roller 35, an output shaft 36, an output motor 37, and a fixing frame 38. The adjusting screw 34... Both ends are fixed on the fixed frame 38; the output roller 35 is fixedly sleeved on the output shaft 36, the output shaft 36 is fixed on the output end of the output motor 37, and the output motor 37 is fixedly installed on the top of the main support 1; the shearing arm 4 is rotatably connected in the main support 1, and one side of the shearing arm 4 is rotatably connected to the output end of the hydraulic cylinder 5; the hydraulic cylinder 5 is rotatably connected in the main support 1, and the shearing arm 4 rotating in the main support 1 is the main output component of the hydraulic shear. With the hydraulic cylinder 5, the shearing arm 4 can be opened and closed to realize the shearing process of the steel billet;

[0021] Specifically, in use, firstly, the main support 1 is supported by the fixed frame 38 and the adjusting screw 34. The adjusting sleeve 31, which is rotatably connected to the main support 1, is connected to the adjusting screw 34 through the internally embedded ball nut, forming a sliding connection structure of the main support 1. The output motor 37 drives the output shaft 36 to rotate, which in turn drives the adjusting roller 32 and the adjusting sleeve 31 to rotate through the output roller 35 and the transmission belt 33, thereby allowing the main support 1 to slide between the fixed frames 38. By arranging multiple sets of fixed frames 38, a section of steel billet can be processed simultaneously. The shearing mechanism allows for easy adjustment of the spacing between the main supports 1 as needed, improving the processing efficiency of the continuous casting machine. The guide shell 23 slides to support the telescopic arm 24, forming a ring clamping structure. Before shearing, the lifting cylinder 21 drives the connecting frame 22 to move up and down, which can adjust the clamping center height of the ring clamping structure. During shearing, the first cylinder 27 and the symmetrically distributed second cylinders 28 drive the clamping block 29 to move closer and fix the steel billet. This ensures shearing accuracy and allows for adaptation to steel billets of different sizes without manual intervention, improving the practicality of the device.
