[0020] As Figure 1As shown, the present application provides a kind of cold-rolled steel coil overflow edge repair device provided in the embodiment, comprising: main portal 100, saddle 200, repair hammer 400 and lifting device;Wherein, saddle 200 is located in main portal 100, for supporting cold-rolled steel coil 300;Repair hammer 400 is hung in main portal 100, and repair hammer 400 can do pendulum motion;Lifting device is set on main portal 100, and lifting device is connected with repair hammer 400 by connecting piece 430 and drives repair hammer 400 to move up and down along Z axis.
[0021] When it needs to repair cold-rolled steel coil, cold-rolled steel coil is supported and fixed on saddle 200, adjust repair hammer 400 to predetermined position by lifting device, push repair hammer 400, so that repair hammer 400 does pendulum motion, hammering overflow edge position of cold-rolled steel coil, until the steel coil is repaired to meet the packaging standard.By adjusting the position of repair hammer 400 and pushing repair hammer 400, the hammering of repair hammer 400 on cold-rolled steel coil is more accurate, and it is convenient to operate, and it needs fewer operators, reduces the safety risk, and improves the work efficiency.In order to facilitate knocking, the repair hammer 400 weighs about 45kg, and the swing angle is about 0 to 45 degrees.Preferably, connecting piece 430 can be chain, steel rope, etc.It should be noted that the cold-rolled steel coil overflow edge repair device in the embodiment meets the repair when the steel coil is in the offline online state, and the repair methods are consistent.
[0022] As shown in the figure, Figure 1 In the embodiment, the lifting device is winch 500, and the connecting piece 430 is wound around the drum of the winch 500, so that the winch 500 can drive the repair hammer 400 to move up and down in Z direction.
[0023] As shown in the figure, Figure 2 Preferably, the cold-rolled steel coil overflow edge repair device further comprises sliding structure 110 arranged on main portal 100, the sliding structure 110 comprises slide rail 111 arranged on main portal 100 and extending forward and backward along X axis, and sliding block 112 which can slide in the slide rail 111;The sliding block 112 is connected with the lifting device.By sliding of lifting device on slide rail 111, the movement of repair hammer 400 in X direction is driven.
[0024] As shown in the figure, Figure 3 Preferably, the repair hammer 400 comprises knocking part 410, and the knocking part 410 is made of hard plastic material PPS.In the embodiment, the knocking part 410 can be made of hard plastic material pps with a thickness of 10cm, which has high-performance thermoplastic resin, high mechanical strength, high temperature resistance, chemical resistance, flame retardant and good thermal stability.Using this material to hammer the steel coil can effectively repair the overflow edge and ensure that there is no debris left on the end face of the steel coil.
[0025] As Figure 3 shown, preferably, the repair hammer 400 includes a hand-held portion 420, the center of gravity of the repair hammer 400 is located at the hand-held portion 420, and the extension line of the connecting member 430 passes through the center of gravity of the repair hammer 400. The extension line of the connecting member 430 passing through the center of gravity of the repair hammer 400 can ensure that the repair hammer 400 is approximately in a balanced state when hanging on the connecting member 430, facilitating the adjustment of the position of the repair hammer 400 and the pushing of the repair hammer 400 when knocking.
[0026] As Figure 3 shown, the connecting member 430 is detachably connected with the repair hammer 400, facilitating the replacement and repair of the repair hammer 400. In the embodiment, a lifting ring 431 is arranged on the hand-held portion 420 of the repair hammer 400, and a lifting hook 432 is arranged on the free end of the connecting member 430, and the detachable connection between the repair hammer 400 and the connecting member 430 is realized through the connection between the lifting hook 432 and the lifting ring 431.
[0027] The general process of repairing the steel coil by using the cold-rolled steel coil overflow edge repairing device is as follows. First, the cold-rolled steel coil overflow edge repairing device is transported to the working position, that is, the online saddle 200 is located in the main portal 100 of the cold-rolled steel coil overflow edge repairing device. The exit personnel checks the appearance quality and information of the steel coil produced online. When the overflow length of the strip steel (that is, the length of the overflow strip steel beyond the two end faces of the steel coil drum) is greater than 10 cm, the steel coil is lifted off the production line for offline repair. When the overflow length of the strip steel is less than 10 cm, the cold-rolled steel coil is centered on the online saddle 200, the overflow edge value is measured and recorded, and the position of the repair hammer 400 is adjusted through the lifting device and the sliding structure to impact the overflow edge position until the cold-rolled steel coil meets the packaging requirements. In actual production process, the repair object requires 1-2 circles of overflow on the inner and outer edges; wherein the overflow length of the strip steel is ≤10 cm; the thickness of each layer of strip steel is ≤7 mm. If it exceeds the range, offline repair, cutting or re-repair on the machine can be considered. The standard for meeting the packaging is that the overflow length of the inner circle of strip steel is ≤1 cm, the overflow length of the outermost circle of strip steel is ≤2 cm, and there is no foreign matter residue. When using the cold-rolled steel coil overflow edge repairing device to repair the cold-rolled steel coil, it is also necessary to wear labor protection gloves, and the swing of the balance hammer should not be too large during use to prevent injury or damage to the steel coil.
