Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of rotary circular knife cutting, and in particular, to a slitting machine for strip steel production. Background Art

[0002] Strip steel, also known as steel strip, is one of the indispensable basic materials in modern industry and is widely used in many fields such as construction, automobiles, home appliances, and machinery manufacturing. Strip steel is a narrow and long steel plate produced by various steel rolling enterprises in order to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. The steel strip needs to be stripped during the production process, which means that the wide rolled steel strip is cut into narrower steel strips through specific equipment and processes. The most common way to split is to pull the steel coil and use a rotating disc blade to continuously longitudinally cut the moving steel strip during the pulling process. During shearing, the steel coil is fixed by the machine tool and is accurately cut into the required width or shape under the high-speed rotation of the disc knife. However, in actual use, the existing equipment lacks an opening with precise positioning corresponding to the disc knife before the strip is cut by the disc knife. When the steel coil without the positioning opening directly contacts the disc knife, the edge of the steel coil suddenly contacts the blade of the disc knife, which suddenly generates a cutting force. This force lacks constraint and may cause the cutting angle to shift if it relies solely on the pulling of the steel coil, resulting in uneven width on the left and right sides of the front end of the cut strip. Summary of the invention

One end of the gun blade 48 is in the shape of a triangle, so the rolled opening is also a triangular incision, which corresponds to the circular saw 66 one by one. When the third motor 68 rotates clockwise, the rotational force will be transmitted to the multiple circular saws 66 through the round shaft 65 through the universal rod 67. When the steel strip is pulled from left to right, the circular saw 66 will cut through the preset opening, which solves the problem that when a steel coil without a positioning opening directly contacts the disc knife, the edge of the steel coil suddenly contacts the blade of the disc knife, which will suddenly generate a cutting force. This part of the force lacks constraints, and relying solely on the pulling of the steel coil may cause the cutting angle to shift. The rotating assembly 2 includes two telescopic mechanisms on the left and right. The telescopic mechanism on the left includes a column 21, which is fixedly mounted on the top of the bottom plate 1.

Place the hollow coil core of the steel coil on the outer edge of the multiple arc-shaped bars 27. After adjusting the position, the first hydraulic rod 23 increases the stroke, the crossbar 24 moves, and the connecting pieces 26 of the telescopic mechanism on both sides push the multiple arc-shaped bars 27 to expand, so that the steel coil can be fixed; The loading assembly 3 includes two rails 31, both rails 31 are fixedly installed on the top of the bottom plate 1, both rails 31 are movably connected with movable blocks 32, both movable blocks 32 are equipped with electric wheels and can move in the rails 31, and second hydraulic rods 33 are fixedly installed on the tops of the two movable blocks 32, and the telescopic ends of the two sets of second hydraulic rods 33 are fixedly connected with a support plate 34, and an electric telescopic rod 35 is fixedly installed on the front bottom of the support plate 34, and the telescopic end of the electric telescopic rod 35 is connected with a square plate 36, and two guide wheels 37 are rotatably installed on the front side of the square plate 36; First, place the steel coil on the support plate 34, and the movable block 32 moves toward the rotating assembly 2 in the track 31, and the second hydraulic rod 33 is used to adjust the height of the steel coil in the longitudinal direction. After the feeding assembly 3 inserts the coil core of the steel coil into the outer edge of the rotating assembly 2, the support plate 34 is moved to the right again, and the stroke of the electric telescopic rod 35 is shortened, driving the guide wheel 37 to cross the arc surface where the support plate 34 is located. At this time, the outer edge of the steel coil can be pushed by the two guide wheels 37. When the steel coil is pushed to a suitable position, it can be fixed by unfolding the rotating assembly 2; The clamping assembly 5 includes a bent rod 51, which is fixedly mounted on the left side of the gantry 41. The other end of the bent rod 51 is fixedly connected to a C-shaped plate 52. Two electromagnets 53 are fixedly mounted on the top of the C-shaped plate 52.

At this time, the steel strip is pulled from left to right by the auxiliary pulling device. During the pulling process, the circular saw 66 will cut through the preset opening. By driving the second motor 62, the longitudinal position of the rectangular plate 64 in the bracket 61 can also be adjusted, so as to adjust the longitudinal position of the entire circular shaft 65 and the circular saw 66, so as to achieve flexible cutting of the cutting angle of the steel coil. During the up and down movement of the circular shaft 65, the circular shaft 65 will always be connected to the third motor 68 through the transformation of the universal rod 67; The discharging assembly 7 includes two arc seats 71, which are fixedly mounted on the right side of the two brackets 61. Three elliptical grooves 72 are provided in the two arc seats 71, and rollers 73 are installed in the three elliptical grooves 72. Both ends of the three rollers 73 are connected with connecting rods 74, and the other ends of the three groups of connecting rods 74 are movably mounted in the vertical rails 75; the three rollers 73 are movably hinged between the connecting rods 74 on both sides, and the three groups of connecting rods 74 are movably mounted in the vertical rails 75 through electric wheels, and can move up and down in the vertical rails 75; The cut narrow steel strip is wound around the top of the first roller 73 on the left, and then wound downwardly around the bottom surface of the middle roller 73, and finally pulled out from the top surface of the right roller 73. At this time, the three connecting rods 74 move downward in the vertical rail 75, driving the three rollers 73 to move downward, tightening the steel strip wound thereon; The winding assembly 8 includes an L-shaped rod 81, which is fixedly mounted on the top of the bottom plate 1.

The separating rings 83, the circular saw 66 and the gun blade 48 are in the same straight line in the horizontal space, and the separating rings 83 are configured to be quickly removed from the outer edge of the rotating shaft 82. The tightened strip steel is then wound around the outer edge of a rotating shaft 82 separated by a plurality of separation rings 83. When the rotating shaft 82 rotates clockwise, the first motor 22 and the third motor 68 rotate synchronously, and the overall equipment can complete the operations of pulling out, splitting and rewinding the rolled steel strip.

[0027] Working principle: When using the present invention, an additional steel coil pulling device is required to install and lay the steel belt on the overall equipment. First, the steel coil is fixed by the rotating component 2. The hollow coil core of the steel coil is placed on the outer edge of the multiple arc-shaped strips 27. After adjusting the position, the first hydraulic rod 23 increases the stroke, the crossbar 24 moves, and the connecting pieces 26 of the telescopic mechanism on both sides push the multiple arc-shaped strips 27 to expand, thereby fixing the steel coil. If the diameter or weight of the steel coil is too large, the feeding assembly 3 can also be started, and the steel coil is first placed in the support plate 34, and the movable block 32 moves toward the rotating assembly 2 in the track 31, and the height of the steel coil in the longitudinal direction is adjusted by the second hydraulic rod 33. After the feeding assembly 3 inserts the coil core of the steel coil into the outer edge of the rotating assembly 2, the support plate 34 is moved to the right again, and the stroke of the electric telescopic rod 35 is shortened, driving the guide wheel 37 to cross the arc surface where the support plate 34 is located. At this time, the outer edge of the steel coil can be pushed by the two guide wheels 37. When the steel coil is pushed to a suitable position, the rotating assembly 2 is unfolded to fix the steel coil; After the fixation is completed, one end of the steel strip is pulled through the bent rod 51 and inserted into the return block 43. At this time, the two electromagnets 53 are energized to generate magnetism, and the steel coil will be adsorbed on the bottom surface of the electromagnet 53, and the iron block 55 in the circular groove 54 will also be attracted to clamp the steel strip; After the clamping assembly 5 clamps the steel strip, the two telescopic blocks 46 are started. The two telescopic blocks 46 drive the three long slots 45 to roll the edge of the steel strip downward through the round rod 47, and open the right side of the steel strip. One end of the gun knife 48 is in the shape of a triangle, so the rolled opening is also a triangular incision. After the opening is completed, the clamping of the clamping assembly 5 is canceled, and the opened steel strip is pulled out of the return block 43. The two third hydraulic rods 42 are contracted to drive the return block 43 to move upward for a distance, and the steel strip is reinserted into the gap between the return block 43 and the round roller 44. At this time, the steel strip with an opening at the front end is matched one by one with the circular saw 66 through the auxiliary pulling device, and the third motor 68 rotates clockwise, and the rotation force is transmitted to the multiple circular saws 66 through the circular shaft 65 through the universal rod 67, so that they also rotate clockwise. At this time, the steel strip is pulled from left to right through the auxiliary pulling device. During the pulling process, the circular saw 66 will cut through the preset opening. By driving the second motor 62, the longitudinal position of the rectangular plate 64 in the bracket 61 can also be adjusted, so as to adjust the longitudinal position of the entire circular shaft 65 and the circular saw 66, so as to achieve flexible cutting of the cutting angle of the steel coil. During the up and down movement of the circular shaft 65, the circular shaft 65 will always be connected to the third motor 68 through the transformation of the universal rod 67; The cut narrow steel strip is wound around the top of the first roller 73 on the left, then wound downwardly around the bottom surface of the middle roller 73, and finally pulled out from the top surface of the right roller 73. At this time, the three connecting rods 74 move downward in the vertical rail 75, driving the three rollers 73 to move downward, thereby tightening the steel strip wound thereon; the tightened steel strip is then wound around the outer edge of the rotating shaft 82 separated by a plurality of separating rings 83. When the rotating shaft 82 rotates clockwise, the first motor 22 and the third motor 68 rotate synchronously, and the overall equipment can complete the operations of pulling out, splitting and rewinding the rolled steel strip.
