Description

Technical Field

[0001] The utility model relates to the field of steel plate production, in particular to a fast edge-pull device and a steel plate production line. Background Art

[0002] At present, in the medium and thick plate production line, the steel plates have different degrees of deviation during transportation. Before the head shear, double-sided shear, and cut-to-length shear, the steel plates need to be placed against the fixed side before the head and tail can be cut, segmented, and the sides of the steel plates can be cut. The device for bringing the steel plates to the edge mainly includes a magnetic centering device: that is, the steel plates that need to be brought to the edge are lifted by the lifting hydraulic cylinder, and then the position of the magnetic heads at the head and tail ends is adjusted by the transverse hydraulic cylinder to adjust the alignment of the steel plates. On the one hand, this operation mainly depends on the proficiency of the operator, and the lifting and transverse movement time can easily cause an annual production bottleneck for the production rhythm.

[0003] The above-mentioned magnetic centering device is used to set two to several groups of magnetic centering according to the longest steel plate according to the different lengths of the steel plates. The distance between each group of centering is about 6-8 meters. When the steel plates need to be aligned, the corresponding number of magnetic centering devices are selected according to the length of the plates. First, the magnetic head is lifted by the lifting hydraulic cylinder, and the magnetic head magnetically attracts the steel plate that needs to be aligned. Then, the position of the head and tail magnetic heads is adjusted by the transverse hydraulic cylinder to align the steel plates, and the steel plates are transversely moved to the fixed side by the transverse cylinder. The magnetic head is powered off and the magnetism is removed, and finally the magnetic head is lowered back to the initial position.

[0004] However, in the above scheme, the two horizontal movement cylinders at the head and tail of the steel plate are operated by the operator on site while watching and jogging, which may cause human error. In addition, the total time of the above-mentioned entire side movement cycle usually takes more than 10 seconds, which is too long and affects the process rhythm of the production line. In addition, due to the large spacing between each set of magnetic heads, the lower surface of the thin steel plate may be scratched during horizontal movement.

[0005] In order to avoid possible scratches on the lower surface of the thin steel plate, some existing production lines will add a roller beam device on the basis of magnetic centering. According to the longest steel plate length, a roller beam is set every two meters. When it is necessary to move to the edge, the roller beam is lifted before or at the same time as the magnetic head. The other steps are basically the same as the above scheme. However, due to the addition of the roller beam lifting link, the operation time is longer than the above scheme, and the economic cost is also increased. Utility Model Content

[0028] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, this embodiment provides a rapid edge-pull device, including a fixed support 1, a lifting beam 2 and a driving device 4; the first end of the lifting beam 2 is hinged to the fixed support 1, and a edge stopper 3 is provided on the lifting beam 2 near the fixed support 1; the lifting beam 2 is used to be arranged between two adjacent rollers of a steel plate production line and when the lifting beam 2 is in a horizontal position, its position height is lower than the roller surface of the roller; the driving device 4 is connected to the second end of the lifting beam 2 and can drive the lifting beam 2 to swing around the fixed support 1.

[0030] Among them, when in use, several fast side-pull devices can be set up in the steel plate production line according to the length of the steel plate. During production, the steel plate is transported on the roller conveyor, and the steel plate that deviates (i.e. Figure 1The steel plate 5) that needs to be pulled to the side is parked on the roller conveyor provided with the pulling device. The lifting beam 2 is located between two adjacent rollers in the initial position, and the initial position is lower than the roller surface. The length direction of the lifting beam 2 is set in the horizontal direction, and its top surface is in the horizontal plane. According to the different lengths of the steel plates, all the lifting beams 2 within the length range of the steel plates are lifted by the driving device 4. After the lifting beam 2 rotates to a certain angle around the axis of the hinge position of the fixed support 1, the steel plate will slowly move by its own weight until it hits the pulling-to-side stopper 3, and then automatically stops with the edge. The lifting beam 2 returns to the initial horizontal position through the driving device 4, and the steel plate also falls back to the roller surface.

[0031] Therefore, the rapid edge-pull device in this embodiment only needs the driving device 4 to drive the lifting beam 2 to swing up and down, and the steel plate can be pulled to the edge by relying on its own weight. The steps are simple and do not require the intervention of workers, thus avoiding the uncontrollable factors that may exist in human error operations. It not only avoids improper operation but also saves time. The time consumed to achieve the same edge-pull requirement is shorter, which improves the production rhythm. In addition, the economic investment is also smaller than that of existing equipment.

[0032] In the specific implementation, refer to Figure 1 A plurality of first rollers 21 are provided on the lifting beam 2 and are spaced apart between the edge stopper 3 and the second end of the lifting beam 2 .

[0033] By using a lifting beam 2 with rollers, the steel plate can be automatically aligned with the edge by rolling down under its own weight, thereby reducing scratches on the lower surface of the steel plate.

[0034] After the lifting beam 2 is rotated to a certain height along the fixed support 1 by the driving device 4, the steel plate originally located on the roller is lifted by the raised lifting beam 2, and the steel plate starts to move to the left through the first roller 21 installed on the lifting beam 2 until it hits the edge stopper 3 and stops. The edge stopper 3 makes the edge of the steel plate flush, and the lifting beam 2 returns to the initial horizontal position through the driving device 4, and the steel plate falls back onto the roller.

[0035] The above-mentioned edge stopper 3 is mainly used to position the steel plate against the edge after rolling. Its structure and fixing method can be the following three:

[0036] The first one: reference Figure 1 The edge stopper 3 includes a fixing frame 31 and a baffle 32. One end of the fixing frame 31 is movably disposed on the lifting beam 2 and can move along the length direction of the lifting beam 2. The other end of the fixing frame 31 is fixedly connected to the baffle 32. The entire edge stopper 3 is designed to be movable, and the edge position can be changed by moving.

[0037] The second type: the side stopper 3 includes a baffle 32, and the baffle 32 and the lifting beam 2 are an integrally formed structure. The baffle 32 and the lifting beam 2 are made into one piece, and can be rotated and lifted together with the lifting beam 2.

[0038] In the first and second structures, the plate surface of the baffle 32 should be perpendicular to the length direction of the lifting beam 2.

[0039] The third type: the side stopper 3 adopts a roller structure, refer to Figure 2 The edge stopper 3 includes a fixing frame 31 and a second roller 33 , one end of the fixing frame 31 is fixed on the lifting beam 2 , and the second roller 33 is rotatably arranged at the other end of the fixing frame 31 , and the axis of the second roller 33 is perpendicular to the top surface of the lifting beam 2 .

[0040] Specifically, the other end of the fixing frame 31 is connected with a pin shaft 34 , the axis of the pin shaft 34 is perpendicular to the top surface of the lifting beam 2 , and the second roller 33 is sleeved on the pin shaft 34 via a bearing 35 .

[0041] Of course, the structure and fixing method of the edge stopper 3 are not limited to the above three methods, and other forms can be adopted as needed. This embodiment is only an example.

[0042] The driving device 4 can be a driving cylinder, such as a hydraulic cylinder or a pneumatic cylinder, and the telescopic rod of the driving cylinder is hinged to the bottom of the second end of the lifting beam 2. In order to facilitate the connection, a connecting seat 22 is provided at the bottom of the second end of the lifting beam 2, and the telescopic rod is hinged to the connecting seat 22. When working, the steel plate can be moved to the side and returned to the roller table by only extending and retracting the telescopic rod of the driving cylinder, which is simple and convenient.

[0043] Of course, the driving device 4 may also adopt other driving modes such as an electric motor, a hydraulic motor, etc. as needed. This embodiment is only for illustration.

[0044] Furthermore, the present embodiment also provides a steel plate production line, which includes a roller conveyor and a plurality of the above-mentioned rapid edge-pull devices; the roller conveyor includes a plurality of rollers arranged in parallel and at intervals, and the rapid edge-pull device is arranged between two adjacent rollers.

[0045] This steel plate production line can be suitable for medium and thick plate production lines, hot rolling mills and other plate and strip production lines. It has the same effect as the above-mentioned rapid edge-pull device. It uses the lifting beam 2 to swing upward and uses the steel plate's own weight to quickly pull to the edge. It not only avoids the defects of manual misoperation, but also improves the production rhythm at the location, overcoming the defects of the prior art.

[0046] The above is only an illustrative embodiment of the utility model, and is not intended to limit the scope of the utility model. Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model.
