Description

Technical Field

[0001] The invention belongs to the technical field of steel coil shearing, in particular to a steel coil shearing machine. Background Art

[0002] Steel coil is a rolled steel material for easy storage, transportation and processing. Steel coil is usually processed by stamping technology to produce and process some parts, which are suitable for industries such as petroleum, chemical, construction, medicine, food, machinery, etc.

[0003] When the steel coil is being stamped, the crane is used to lift the steel coil from the storage area to the feeder. After the steel coil is pressed and fixed, the steel tie on the outer ring of the steel coil is cut open, and the feeder sends the material strip to the mold on the stamping machine. The stamping machine drives the mold to stamp the product on the material strip.

[0004] Steel coils are prone to collisions during transportation and storage, causing large bending deformations at the ends of the steel coils. The bent and deformed ends of the steel coils cannot pass through the die of the punching machine. At this time, workers are required to use cutting equipment to cut off the bent and deformed ends of the steel coils. Manually operated cutting machines are difficult to cut, and the high-temperature splashes, rebound when the steel coils are broken, and the falling of deformed steel coils can easily cause injuries to workers.

[0053] Working principle: Place the end of the steel coil material belt into the feeding unit on the side of the feeding end of the machine body 1, and the No. 2 motor 29 drives the No. 1 gear 30 to rotate, drives the No. 1 face gear 28 meshing with it to rotate, drives the No. 1 screw rod 27 to rotate, and drives the two sliding beams 22 to move relative to each other; when it is necessary to drive the steel coil material belt to move, the driving component drives the two sliding beams 22 to approach each other, so that the two driving rollers 23 clamp the two sides of the steel coil material belt. At this time, the No. 1 motor 24 drives the pulley 25 to rotate, and through the transmission of the belt 26, drives the driving roller 23 to rotate, so that the clamped steel coil material belt moves; the steel coil material belt passes through the inner cavity of the machine body 1, so that the steel coil material belt passes through the middle of the cutting fixed frame 2, so that the bottom of the steel coil material contacts the top of the fixed cutting knife 3;

[0054] When the deformed end of the steel coil material strip passes through the feeding unit at the discharge end of the machine body 1, the No. 1 hydraulic cylinder 9 pushes the crossbeam 10 to descend, driving the flattening top seat 11 to descend, so that the flattening top seat 11 cooperates with the flattening base 5 to clamp and fix the steel coil material strip, so that the bottom surface of the steel coil material strip is close to the top surface of the fixed cutting knife 3; at this time, the No. 2 hydraulic cylinder 16 drives the slide 13 to slide downward along the vertical guide rail 12, and through the connection of the connecting plate 15, multiple slides 13 maintain a horizontal state and move synchronously, the slide 13 drives the fixed plate 14 to descend, drives the cutter 4 to move downward, and cooperates with the fixed cutting knife 3 to cut the steel coil material strip; the cutting unit is reset, so that the flattening top seat 11 and the movable cutter 4 move upward, loosen the steel coil material strip, and the feeding unit at the discharge end of the machine body drives the deformed end of the steel coil material strip out of the machine body 1;

[0055] Afterwards, the third motor 37 drives the second gear 38 to rotate, drives the second face gear 36 to rotate, drives the second screw rod 35 to rotate, and drives the two lifting beams 32 to approach each other, so that the top conical grinding head 34 contacts the top of the cut-off opening of the steel coil material strip, and the bottom conical grinding head 34 contacts the bottom of the cut-off opening of the steel coil material strip; the fourth motor 42 drives the fourth gear 43 to rotate, drives the third face gear 44 to rotate, drives the rotating rod 40 to rotate, drives the third gear 41 to rotate, and through the meshing transmission between multiple third gears 41, multiple rotating rods 40 rotate, drive multiple conical grinding heads 34 to rotate, and at the same time, the slider of the linear slide rail 33 drives the conical grinding head 34 to move, grinds the cut-off opening of the steel coil material strip, and removes burrs from the cut-off opening of the steel coil material strip. At the same time, the air outlet nozzle 45 sprays high-speed airflow to blow away burrs and debris from the steel coil material strip and the conical grinding head 34;

[0056] At the same time, the conveying unit at the feeding end of the machine body 1 continues to convey the steel coil material strip forward, and the No. 3 hydraulic cylinder 47 pushes the deburring fixing frame 31 to move along the through groove 46 toward the discharging end of the machine body 1; thereafter, the deburring unit is reset, so that the conical grinding head 34 is separated from the cut-off end of the steel coil material strip, so that the steel coil material strip passes through the conveying unit at the discharging end of the machine body 1; the feeding units at both ends of the machine body 1 convey the flattened steel coil material strip to the stamping machine for processing; thereby avoiding high-temperature splashes generated during the cutting of the steel coil material, rebound when the steel coil material strip is broken, and the falling of the deformed steel coil; reducing the probability of danger to the staff, facilitating the operation of the staff, and improving the work efficiency of the staff.
