[0022] A positioning device for feeding steel billets in a steel rolling heating furnace, including a positioning frame 1, a support plate 2 and an auxiliary frame 3. The support plate 2 is installed on one side above the positioning frame 1, the auxiliary frame 3 is installed on one side of the support plate 2, a conveying roller 203 is installed above the support plate 2, and a positioning frame 1 is installed between one side of the support plate 2 and the positioning frame 1. A hydraulic cylinder 105 is installed between the lower end of the support plate 2 and the positioning frame 1. A support frame 104 is installed below the positioning frame 1, and the support frame 104 is welded to the positioning frame 1. Both ends of the hydraulic cylinder 105 are respectively movably connected to the positioning frame 1 and the support plate 2 through connecting ears. The support plate 2 is supported and limited by the hydraulic cylinder 105. After the steel billet 4 to be processed is pressed on the support plate 2, the support plate 2 conveys the steel billet 4 to be processed through the conveying roller 203. Through the cooperation of the movable shaft 103 and the hydraulic cylinder 105, the two positioning frames 1 are evenly stressed, which can effectively improve the stability effect and assist in the feeding work.

[0023] There are two positioning frames 1, two support plates 2, and two auxiliary frames 3. An anti-slip cushion plate 106 is installed between the two positioning frames 1, and the anti-slip cushion plate 106 is fixedly connected to the two positioning frames 1 respectively. A connecting pipe 204 is installed between the two support plates 2, and the connecting pipe 204 is fixedly connected to the conveying roller 203 through a coupling. A steel billet 4 to be processed is arranged above the conveying roller 203. During the use of the positioning frame 1, by installing the support plate 2, the conveying roller 203 above the support plate 2 conveys the steel billet 4 to be processed.

[0024] Specifically, during the use of the positioning frame 1, by installing the support plate 2, the conveying roller 203 above the support plate 2 conveys the steel billet 4 to be processed. During the conveying process, the support plate 2 is supported and limited by the hydraulic cylinder 105. After the steel billet 4 to be processed is pressed above the support plate 2, the support plate 2 conveys the steel billet 4 to be processed through the conveying roller 203. By means of the movable shaft 103 cooperating with the hydraulic cylinder 105, the two positioning frames 1 are evenly stressed, which can effectively improve the stability effect and assist in the feeding work.

[0025] In order to solve the problem that the existing positioning device has general strength and the overall position of the device is unstable after being subjected to the pressure of the steel billet during actual use, please refer to Figure 1 - Figure 3 This embodiment provides the following technical solutions:

[0026] There is an integrally formed movable opening 101 between the positioning frame 1 and the support plate 2. A movable shaft 103 is installed inside the movable opening 101, and the support plate 2 is rotatably connected to the positioning frame 1 through the movable shaft 103. A damping cushion layer 102 is installed above the movable opening 101, and the damping cushion layer 102 is fixedly connected to the positioning frame 1 and the support plate 2 respectively. During the movement of the auxiliary frame 3, it is restricted by the high-pressure spring 202 and the electric cylinder 201 to squeeze the steel billet 4 to be processed. The pressure generated during the movement of the steel billet 4 to be processed is buffered by the damping cushion layer 102, thereby improving the position stability and being beneficial for long-term work.

[0027] A high-pressure spring 202 and an electric cylinder 201 are installed on one side of the support plate 2. A fixed disk 303 is installed at one end of the auxiliary frame 3. The two ends of the electric cylinder 201 and the high-pressure spring 202 are fixedly connected to the support plate 2 and the auxiliary frame 3 respectively through the fixed disk 303. A protective cover 301 is installed outside the auxiliary frame 3. The protective cover 301 is set as an inclined heat-insulating frame body, and an adjusting roller 302 is installed inside the protective cover 301. The adjusting roller 302 is rotatably connected to the protective cover 301 through a bearing. By installing the auxiliary frame 3 on one side of the support plate 2, during the working process of the auxiliary frame 3, the adjusting roller 302 distributed obliquely assists the steel billet 4 to be processed to move above the conveying roller 203, making the position of the steel billet 4 to be processed more stable and improving the feeding efficiency.

[0028] Specifically, an auxiliary frame 3 is installed on one side of the support plate 2. During the working process of the auxiliary frame 3, the adjustment rollers 302 distributed obliquely assist the billet 4 to be processed to move above the conveying rollers 203, making the position of the billet 4 to be processed more stable, thereby improving the feeding efficiency. Moreover, during the movement of the auxiliary frame 3, it is restricted by the high-pressure spring 202 and the electric cylinder 201 to extrude the billet 4 to be processed. The pressure generated during the movement of the billet 4 to be processed is buffered by the damping cushion layer 102, thereby improving the position stability and being conducive to long-term operation.

[0029] Working principle: When in use, after the billet 4 to be processed that needs to be conveyed and fed moves above the support plate 2, the conveying rollers 203 convey the billet 4 to be processed. During the conveying process, the support plate 2 is supported and limited by the hydraulic cylinder 105. After the billet 4 to be processed presses on the support plate 2, the support plate 2 conveys the billet 4 to be processed through the conveying rollers 203. By means of the movable shaft 103 cooperating with the hydraulic cylinder 105, the two positioning frames 1 are balanced in force, which can effectively improve the stability effect and assist in the feeding work. An auxiliary frame 3 is installed on one side of the support plate 2. During the working process of the auxiliary frame 3, the adjustment rollers 302 distributed obliquely assist the billet 4 to be processed to move above the conveying rollers 203, making the position of the billet 4 to be processed more stable, thereby improving the feeding efficiency. Moreover, during the movement of the auxiliary frame 3, it is restricted by the high-pressure spring 202 and the electric cylinder 201 to extrude the billet 4 to be processed. The pressure generated during the movement of the billet 4 to be processed is buffered by the damping cushion layer 102, thereby improving the position stability and being conducive to long-term operation.
