Description

Technical Field

[0002] Cold rolled sheet is a process that presses, stretches and shapes metal sheets through a rolling mill at room temperature to achieve the required size and surface quality. Cold rolled sheets are stored in coils. When processing cold rolled sheets, the coils are usually continuously rotated and released on the conveyor line in the workshop. Different industries, engineering projects or manufacturing processes often require cold rolled sheets of different specifications and sizes. By longitudinally shearing the coiled cold rolled sheets and dividing them into multiple sections when they are released, the customized needs of various customers can be met.

[0003] The longitudinal shearing device is installed on the conveyor line of the cold-rolled plate, and the longitudinal shearing device is mainly composed of two symmetrical rollers. The two rollers are driven by a driving device to rotate and turn in opposite directions. The outer wall of the upper roller is connected to multiple blades arranged at equal intervals, and the outer wall of the lower roller is provided with an annular groove that is adapted to and corresponds to the position of the multiple blades. The cold-rolled plate will pass between the two rollers in the conveyor line, and the cold-rolled plate will be longitudinally sheared into multiple sections by multiple blades.

[0004] However, when multiple blades are shearing cold-rolled plates, the blades will gradually wear out, affecting their use. Workers often need to regularly remove the rollers located above to maintain the multiple blades, which is troublesome to operate. In addition, the blades are very sharp, and the operation process has certain safety hazards. To this end, we propose a shearing device for cold-rolled plate production. Utility Model Content

[0023] See also Figure 3 and Figure 5 In the figure, the opening and closing mechanism includes a rotating rod 12 and a plurality of fixing rings 22. The rotating rod 12 is rotatably installed in the inner walls of the plurality of connecting tubes 11 from front to back, and the outer walls of the rotating rod 12 are fixedly connected with push pins 23 corresponding to the plurality of connecting tubes 11, and one end of the rotating rod 12 is fixedly connected with a rotating block 15.

[0025] See also Figure 3 and Figure 5 In the figure, the conical rubber plug 21 is made of polytetrafluoroethylene material; the conical rubber plug 21 made of polytetrafluoroethylene material has high strength and good sealing performance.

[0026] Working principle: The cold-rolled sheet can pass between the rotating roller 1 5 and the rotating roller 2 7 on the conveyor line, and the cold-rolled sheet will be longitudinally sheared into multiple sections by the multiple blades 10 on the outer wall of the roller 1 5. Since the multiple blades 10 are in contact with the cold-rolled sheet for a long time, the blades 10 will gradually be worn. After the longitudinal shearing of the cold-rolled sheet is completed, the rotation of the roller 1 5 and the roller 2 7 is stopped, and then the rotating block 15 is rotated. The rotating block 15 can drive the rotating rod 12 to rotate in the inner wall of the multiple connecting tubes 11, and the rotating rod 12 can drive the multiple push pins 23 to rotate. Each push pin 23 can push the corresponding conical rubber plug 21 above it to move upward. The conical rubber plug 21 will leave the inner side of the fixed ring 22 and drive the guide pin 19 at its upper end to move in the inner wall of the connecting block 20. The conical rubber plug 21 will slide upward, and the conical rubber plug 21 will squeeze the spring 13 connected to the connecting block 20. At this time, the lubricating oil in the oil cylinder 4 can flow down along the gap between the conical rubber plug 21 and the fixing ring 22 and soak into the sponge block 18 in the concave plate 17. Then, the rotating block 15 is rotated back so that the multiple push pins 23 on the outer wall of the rotating rod 12 can leave the bottom ends of the multiple conical rubber plugs 21 respectively. Under the action of the spring 13, the multiple conical rubber plugs 21 can automatically move down and reset and fit tightly against the inner side of the corresponding fixing ring 22, thereby preventing the flow of lubricating oil.

[0027] Then, the two electric push rods 2 are connected to an external power source, so that the two electric push rods 2 can drive the respectively connected connecting columns 3 to move downward, the two connecting columns 3 can drive the oil cylinder 4 to move downward, and the oil cylinder 4 can drive the multiple connecting pipes 11 together with the multiple concave plates 17 and the sponge blocks 18 in the multiple concave plates 17 to move downward until the inner sides of the multiple sponge blocks 18 are respectively attached to the outer surfaces of the multiple blades 10, and then the roller 5 is driven to rotate, so that the outer surfaces of the multiple blades 10 can be evenly coated with lubricating oil, so that the multiple blades 10 can be regularly maintained without disassembling the roller 5, the operation is convenient, and the staff are not easy to touch the blades 10, and the safety is good.
