Description

Technical Field

[0001] The utility model relates to the application field of a casting and rolling mill, in particular to an automatic sheet coiling device for a casting and rolling mill. Background Art

[0002] At present, in the coiling stage of the sheet casting and rolling process, it is found that due to the deviation between the sheet outlet and the jaw position, before the sheet is coiled, it is necessary to manually take the sheet and place it into the jaw. However, this process is very likely to cause the sheet to deform, affecting the later coiling quality of the sheet. Or control the rotation of the reel to adjust the position of the jaw, and then control the reel mechanism to coil the sheet. However, this adjustment process still requires stopping the transportation of the sheet to cooperate with the adjustment of the jaw, delaying the production time and reducing the production efficiency.

[0003] Therefore, in view of the above problems, it is urgent to design an automatic sheet coiling device for a casting and rolling mill. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an automatic sheet coiling device for a casting and rolling mill. Through the design of the deflecting roller mechanism and the reel mechanism, the jaw position of the reel mechanism can be pre-positioned, so that the end position of the support plate is aligned with the jaw position. Thus, during the operation, the sheet can automatically enter the jaw along the end of the support plate without additional manual adjustment and alignment, reducing the labor and improving the production efficiency. And through the design of the sensor, it detects whether the sheet reaches the jaw position, and then feeds back to the control unit. The control unit controls the operation of the reel mechanism to clamp and coil the sheet. The whole process is simple to operate and has a high automation level, which can greatly reduce the labor and improve the production efficiency.

[0005] To solve the above technical problems, the utility model provides an automatic sheet coiling device for a casting and rolling mill, which includes a deflecting roller mechanism and a reel mechanism arranged on one side of the deflecting roller mechanism. The deflecting roller mechanism includes columns, guide rollers, guide plates, guide rolls, support plates and swing rod assemblies. There are two columns and they are symmetrically arranged.

The winding drum is driven to rotate and expand and contract respectively by a speed reducer and an expansion and contraction oil cylinder. A clamping jaw for clamping a plate is arranged on the winding drum. An inductor for detecting the position of the plate in the clamping jaw is arranged at the front end of the support plate. The swing rod assembly is driven by an oil cylinder and drives the support plate to rotate so that the end of the support plate is aligned with the clamping jaw.

[0007] Further, the inside of the guide roller is a hollow structure and one end of it is connected to a hollow shaft. The hollow shaft is connected to a two-way rotary joint.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0030] In a specific embodiment of the present utility model, as Figures 1-7As shown in the figure, an automatic coiling device for a casting-rolling mill includes a deflection roller mechanism 1 and a reel mechanism 2 arranged on one side of the deflection roller mechanism 1. The deflection roller mechanism 1 includes columns 11, guide rollers 12, guide plates 13, guide rollers 14, a support plate 15, and a swing rod assembly 16. There are two columns 11 which are symmetrically arranged. An installation frame 17 is arranged between the two columns 11. The guide roller 12 is rotatably arranged on the installation frame 17. The guide plate 13 is obliquely arranged between the two columns 11, and its upper end faces the guide roller 12, and its lower end extends outside the two columns 11. The guide roller 14 is rotatably arranged on the guide plate 13. A passage for the sheet material to pass through is arranged between the lower part of the guide roller 14 and the guide plate 13.

[0031] The inner side of the upper end of the installation frame 17 is connected with a connecting frame 19 through a first rotating shaft 18. The connecting frame 19 is connected with the support plate 15 through a second rotating shaft 191. A swing rod assembly 16 is arranged at the bottom of the support plate 15. The reel mechanism 2 includes a reel frame and a reel 22 arranged above the reel frame. The reel 22 is driven to rotate and expand and contract respectively through a speed reducer and a telescopic oil cylinder. A clamping jaw 221 for clamping the sheet material is arranged on the reel 22. An inductor (not shown in the figure) for detecting the position of the sheet material in the clamping jaw 221 is arranged at the front end of the support plate 15. The swing rod assembly 16 is driven by an oil cylinder 161 and drives the support plate 15 to rotate so that the end of the support plate 15 approaches the clamping jaw 221.

[0032] As Figure 2 shown in the figure, the inside of the guide roller 12 is a hollow structure and one end of it is connected with a hollow shaft 110. The hollow shaft 110 is connected with a two-way rotary joint 111. An inlet 1111 and an outlet 1112 are arranged on the two-way rotary joint 111. A water inlet pipe 112 communicating with the inlet 1111 and the inner cavity of the hollow shaft 110 is arranged in the guide roller 12. A return water channel 113 is arranged between the water inlet pipe 112 and the inner cavity of the guide roller 12. The return water channel 113 is communicated with the outlet 1112 and the inner cavity of the hollow shaft 110. Specifically, by injecting cooling water into the inlet, the temperature of the guide roller 12 can be reduced during the casting-rolling process, and the service life of the guide roller 12 can be prolonged.

[0033] Specifically, as Figure 2 shown in the figure, at least one of the two columns 11 is provided with a blower 114 at the top. The air outlet of the blower 114 is located above the guide plate 13, and its air outlet direction is perpendicular to the moving direction of the sheet material. Through the design of the blower, not only can the temperature of the sheet material be reduced, but also the dust on the upper surface of the sheet material can be blown off, improving the coiling quality of the sheet material. In this embodiment, the blower is designed as one. Of course, in other embodiments, the blower can be designed as two and arranged symmetrically.

[0034] Specifically, in this embodiment, the oil cylinder 161 is movably mounted on the base through the oil cylinder mounting seat 163 and is located below the guide roller 12. Here, the movable mounting can be a rotating shaft mounting method, which can ensure the normal operation of the oil cylinder 161.

[0035] As Figures 3-4 , in this embodiment, the swing rod assembly 16 includes a fixing plate 162 and a fixing shaft 165. The fixing plate 162 is fixed to the support plate 15. The fixing shaft is arranged in the fixing plate 162, and there is a gap between one end of the fixing shaft and the support plate 15, and the other end is connected to the output end of the oil cylinder 161. Specifically, after the oil cylinder 161 is started, its output end extends out and drives the fixing plate 162 to rotate and drives the support plate 15 to rotate, so that the end of the support plate 15 is aligned with the jaw 221.

[0036] Specifically, in this embodiment, the guide plate 13 is provided with limiting plates 115. There are two limiting plates 115, which are symmetrically arranged outside the guide roller 14. Through the design of the limiting plates, the offset of the plate can be prevented, and the quality of the plate coiling can be improved.

[0037] As Figures 6-7 shown, the reel 22 includes a main shaft 222, and three movable sector plates 223, a first jaw sector plate 224 and a second jaw sector plate 225 arranged along the outer circumferential direction of the main shaft 222. The main shaft 222 is provided with wedges 227 corresponding to the movable sector plates 223. Each wedge 227 can move along the axial direction of the main shaft 222. One side of each wedge 227 away from the main shaft 222 is provided with an inclined surface, and a T-shaped block 228 is fixed on the inclined surface. The T-shaped block 228 moves relative to the inner inclined surface of the corresponding movable sector plate 223, so as to realize the expansion and contraction of the reel. The first jaw sector plate 224 and the second jaw sector plate 225 are respectively fixed to the main shaft 222, and the gap between them forms a plate feeding port. A jaw head 226 is arranged in the plate feeding port. A jaw 221 is formed between the jaw head 226 and the first jaw sector plate 224. As Figure 7 shown is the state where the jaws are clamped. Here, the clamping movement of the jaw head is similar to the structure of the expansion and contraction of the movable sector plate. Figure 7 In

[0038] As Figure 5 shown, the front end of the upper surface of the support plate 15 is provided with a guiding inclined surface 151. This design can leave a gap between the plate and the support plate 15, which is convenient for the plate to enter the jaws for coiling operation.

[0039] The working principle of the present utility model is:

[0040] Start the actuating oil cylinder 161 to extend its output end and drive the fixed plate 162 to rotate, so as to drive the supporting plate 15 to rotate and align the end of the supporting plate 15 with the clamping jaw 221; then start the transmission mechanism of the casting-rolling mill to make the sheet material transmit along the guide plate 13, then pass through the channel between the lower part of the guide roller 14 and the guide plate 13, be supported by the guide roller 12 and transmit it into the connecting frame 19, then enter the clamping jaw 221 along the guiding inclined surface 151 of the supporting plate 15, and then sense whether the sheet material reaches the position of the clamping jaw 221 through the inductor. When it is detected that the sheet material reaches the clamping jaw position, a feedback signal is sent to the control unit, and then the reduction gear and the expansion and contraction oil cylinder are controlled by the control unit to operate, and the sheet material is clamped and coiled.

[0041] The above-disclosed is only a preferred embodiment of the present utility model, and of course it cannot be used to limit the scope of rights of the present utility model. Therefore, equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
