DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] When cutting the hot-rolled coil according to the size required by the customer, a cutting device for hot-rolled coil processing is required. The cutting device for hot-rolled coil processing provided by the utility model fixes the hot-rolled coil during the cutting process to prevent it from deflecting and shaking during the cutting process, thereby affecting the cutting accuracy.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a cutting device for hot-rolled coil processing, comprising a workbench 1, a connecting frame 4 is arranged between the two sides of the workbench 1, a telescopic rod 5 is slidably connected to the inner wall of the top end of the connecting frame 4, a mounting block 6 is fixed to the telescopic end of the telescopic rod 5, a cutting knife is installed at the bottom end of the mounting block 6, a connecting plate 7 is fixed to one end of the mounting block 6, a first screw rod 8 is threaded through the top end of the connecting plate 7, a connecting sleeve 10 is rotatably connected to the bottom end of the first screw rod 8, a moving rod 9 is fixed to the top end of the connecting sleeve 10, the moving rod 9 penetrates the connecting plate 7, a moving plate 15 is slidably connected to the inner wall of the connecting sleeve 10, a plurality of first springs 14 are fixed between the top end of the moving plate 15 and the inner wall of the top end of the connecting sleeve 10, a plug-in 11 is fixed to the bottom end of the moving plate 15, a mounting shell 12 is fixed to the bottom end of the plug-in 11, a pressure sensor 16 is installed in the mounting shell 12, and an extrusion plate 13 is installed at the bottom end of the pressure sensor 16.

[0021] It should be noted that the cutting knife is driven downward by the telescopic rod 5 to cut the hot-rolled coil. During the movement of the telescopic rod 5, the extrusion plate 13 moves downward, contacts and squeezes the surface of the hot-rolled coil, so that the spring is compressed. The spring can provide a certain buffering force to prevent the hot-rolled coil from being crushed during the extrusion process, and is measured by the pressure sensor 16. When the spring force decreases after long-term extrusion, the extrusion of the hot-rolled coil by the extrusion plate 13 becomes smaller. When the value measured by the pressure sensor 16 decreases, the first screw 8 can be rotated to drive the connecting sleeve 10 and the extrusion plate 13 to move downward, so that the bottom end of the extrusion plate 13 clamps the hot-rolled coil to avoid displacement during cutting.

[0022] like Figure 1 and Figure 4As shown, the top of the workbench 1 is located at both ends of the connecting frame 4 and a support frame 3 is fixed thereon. The top of the support frame 3 is screwed with a second screw rod, and the bottom of the second screw rod is rotatably connected to a mounting plate 17. The top of the mounting plate 17 is fixed with a fixing rod, and the fixing rod penetrates and is slidably connected to the support frame 3. The bottom of the mounting plate 17 is fixed with a telescopic member 18, and the bottom of the telescopic member 18 is fixed with a mounting frame, and a rotating cylinder 19 is rotatably connected between the inner walls of both sides of the mounting frame. The telescopic member 18 includes a fixing sleeve fixed to the bottom end of the mounting plate 17, a plug rod is inserted into the fixing sleeve, a second spring is fixed between the top of the plug rod and the inner wall of the fixing sleeve, and the plug rod is fixed to the top of the mounting frame. A conveyor belt 2 is installed in the workbench 1, and a screw rod is rotatably connected between the inner walls of both sides of the connecting frame 4, and a slider is screwed to the outer wall of the screw rod, and the slider is fixed to the top of the telescopic rod 5. A dust collecting member 20 is fixed at one end of the support frame 3, a plurality of dust collecting pipes are fixedly connected to the bottom end of the dust collecting member 20, a collection box 21 is fixed at the top end of the dust collecting member 20, a filter is installed in the collection box 21, a connecting pipe is fixedly connected between the collection box 21 and the dust collecting member 20, and a fan is fixedly connected to the top end of the collection box 21. A controller is installed at one side of the connecting frame 4, and the controller is electrically connected to the telescopic rod 5, the pressure sensor 16 and the fan.

[0023] It should be noted that by adjusting the second screw, the second screw drives the mounting plate 17, the rotating drum 19, the telescopic member 18, etc. to move downward, and the rotating drum 19 contacts the surface of the hot-rolled coil. When the hot-rolled coil moves on the conveyor belt 2, the rotating drum 19 also rotates so that the hot-rolled coil moves more smoothly, and the dust on the surface of the hot-rolled coil can be cleaned by the dust collecting member 20 and sucked into the collection box 21.

[0024] Working principle: The telescopic rod 5 is started by the controller, and the telescopic rod 5 drives the cutting knife to move downward to cut the hot-rolled coil. During the downward movement, the extrusion plate 13 moves downward, contacts and squeezes the surface of the hot-rolled coil, so that the spring is compressed. The spring can provide a certain buffering force to prevent the hot-rolled coil from being crushed during the extrusion process, and is measured by the pressure sensor 16. When the spring elasticity decreases after long-term extrusion, the extrusion force of the extrusion plate 13 on the hot-rolled coil becomes smaller. When the value measured by the pressure sensor 16 decreases, the first screw 8 can be rotated, and the first screw 8 drives the connecting sleeve 10 and the extrusion plate 13 to move downward, so that the bottom end of the extrusion plate 13 clamps the hot-rolled coil to avoid displacement during cutting.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
