DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, the utility model provides a horizontal continuous casting ingot bending detection device, which includes a fixing frame 1, a fixing part 2, a mounting block 3, a mounting seat 4, a bending device 5, a movable part 6 and a control box 7.

[0027] The fixing part 2 is arranged on one side of the top surface of the fixing frame 1, and the fixing part 2 includes two fixing plates 21, a connecting plate 22 and two bending columns 23. The two fixing plates 21 are symmetrically arranged on one side of the top surface of the fixing frame 1, and a bending opening is formed between the two fixing plates 21, which cooperates with the movable part 6 and the bending device 5 to realize the bending of the ingot.

[0028] The two ends of the connecting plate 22 are respectively connected to the top of the two fixing plates 21 to enhance the stability of the fixing part 2. The two bending columns 23 are respectively arranged at one end of the two fixing plates 21 close to the bending mouth, so that the casting billet is bent more smoothly and the sharp parts at the bending mouth can be prevented from scratching the casting billet.

[0029] The fixing portion 2 further includes a reinforcing wing 24 disposed between the fixing plate 21 and the top surface of the fixing frame 1 , which can strengthen the connection strength between the fixing portion 2 and the fixing frame 1 , thereby improving the pressure bearing capacity of the bending opening.

[0030] The movable part 6 is arranged between the fixed part 2 and the mounting block 3, and the movable part 6 includes a fixed sleeve 61, a large cylinder 62 and a small cylinder 63. The fixed sleeve 61 is sleeved on the output shaft of the bending device 5, and is used to connect the movable part 6 and the bending device 5. The large cylinder 62 is fixed on the output shaft of the bending device 5, and is used to transmit the power of the bending device 5; a connecting wing plate is provided between the large cylinder 62 and the fixed sleeve 61, which can improve the connection strength between the large cylinder 62 and the fixed sleeve 61.

[0031] The small cylinder 63 is fixed on the side of the large cylinder 62 near the bending mouth, and is used to contact the middle of the billet to apply bending force to the billet. The axis of the large cylinder 62, the axis of the small cylinder 63 and the center line of the bending mouth are located in the same plane, ensuring the uniformity and accuracy of the bending; the design of the large cylinder 62 and the small cylinder 63 can control the final bending radius while enhancing the connection strength between the movable part 6 and the bending device 5.

[0032] The mounting block 3 is arranged on the other side of the top surface of the fixing frame 1, and the mounting block 3 includes a mounting plate 31 and two reinforcing plates 32. The mounting plate 31 is arranged on the other side of the top surface of the fixing frame 1, and is penetrated by a bending device 5 for fixing the bending device 5. The two reinforcing plates 32 are respectively arranged between one end of the two mounting plates 31 and the top surface of the fixing frame 1, and are used to enhance the stability of the mounting block 3.

[0033] The bending device 5 is arranged between the mounting block 3 and the mounting seat 4. The bending device 5 is a hydraulic cylinder, which can be an oil pressure-driven hydraulic cylinder. One end of the hydraulic cylinder is fixed on the mounting 4 and connected to the control box 7. The output end of the hydraulic cylinder is connected to the movable part 6 for controlling the movement of the movable part 6, thereby realizing the bending of the ingot.

[0034] The control box 7 is arranged on the mounting base 4 and connected to the bending device 5. The control box 7 is an electrical control device, which is equipped with power supply, switches, buttons, display and other components for controlling the working state of the bending device 5, such as bending force, bending speed, bending angle, etc.

[0035] The working principle and use method of the utility model are as follows:

[0036] When it is necessary to inspect the horizontal continuous casting billet, first place the billet to be inspected at the bending mouth of the fixed part 2, so that the two ends of the billet are in contact with the two bending columns 23 respectively, and then start the bending device 5 through the control box 7. As the output shaft of the bending device 5 moves, the movable part 6 also moves accordingly, and the small cylinder 63 pushes toward the bending mouth, applying a bending force to the middle of the billet, so that the billet bends at the bending mouth. When the bending reaches the preset angle, the bending device 5 automatically stops working. Finally, observe whether there are cracks on the surface of the billet. If there are cracks, it means that the quality of the billet is unqualified and needs to be processed or scrapped; if there are no cracks, it means that the quality of the billet is qualified and subsequent processing can be carried out.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
