Description

Technical Field

[0002] Aluminum plate refers to a rectangular plate made by rolling aluminum ingots. It is divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium and thick aluminum plate, and patterned aluminum plate. The current aluminum plate raw materials are mostly set in rolls for easy transportation and sale. During the processing of aluminum plates, the aluminum plate coils need to be unrolled and cut into fixed lengths.

[0003] The current aluminum raw materials will have a certain degree of arc bending during the long-term coiling and placement process. During the slitting process, the arc bending will lead to poor flatness of the coil, resulting in slitting errors.

[0017] The beneficial effects are:

[0018] 1. The fixed roller is driven to rotate by controlling the motor. At this time, the extrusion conveyor belt rotates with it, and the clamping bar contacts the surface of the coil. At this time, the distance sensor is blocked. With the cooperation of the top plate and the translation conveyor belt, the purpose of clamping the coil is achieved. As the clamping bar continues to move to the adjusting roller and then moves upward, the distance between the distance sensor and the surface of the coil changes, and an electrical signal is sent to the digital display controller to control the hydraulic cylinder to drive the oblique blade cutter to move downward. With the cooperation of the cutter groove, the coil is cut.

[0019] 2. Pull the coil from the bottom to make it abut against and bypass the guide roller, and then pass through the clamping strip and the translation conveyor belt in sequence. While the coil passes through the guide roller, the curved plate of the coil is supported in the reverse direction, which can make the coil laid flat on the surface of the table more flat, thereby avoiding slitting errors.

[0020] 3. The bevel cutter continues to move downward. Under the elastic force of the compression spring, the two pressure plates can respectively press down and fix the coils on both sides of the bevel cutter, making the slitting more accurate and smooth, and at the same time ensuring the smooth grinding of the cutting point. When the clamping strip is not in contact with the surface of the coil, the bevel cutter can be partially raised. At this time, the two pressure plates can still press down and fix the ends of the coil under the elastic force of the spring to prevent the coil from inertial rewinding, which not only improves the fixing effect when cutting the coil, but also grinds the burrs at the cutting point while cutting, thereby improving work efficiency.

[0031] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0032] See also Figure 1-Figure 7 As shown, the present invention provides an automatic fixed-length slitting device for aluminum plates, comprising a table top 1, a digital display controller 10, a coil base 14 and an aluminum plate coil 9, a hollow groove 2 is provided through the middle of the upper surface of the table top 1, a translation structure 3 for moving the coil on the surface of the table top 1 is provided below the hollow groove 2, an extrusion driving structure 4 for intermittently conveying the coil on the surface of the translation structure 3 is provided above the hollow groove 2, the end of the table top 1 is rotatably connected to a guide roller 12, and the coil abuts and bypasses the upper side of the guide roller 12, a gantry 13 is fixedly connected to one side of the upper surface of the table top 1, a shearing structure 7 for intermittently slitting the coil is provided below the gantry 13, and a conveying structure 8 for driving the cut aluminum plate to move is provided on the side of the table top 1 away from the guide roller 12;

[0033] There are two coil bases 14, and the upper surfaces of the two coil bases 14 are fixedly connected with support plates 15. Two top support fixing plates 16 are arranged on the upper sides between the two support plates 15, and a reeling drive 6 for driving the two top support fixing plates 16 to rotate is arranged on the upper side of the side wall of one of the support plates 15. It is worth mentioning that when the motor 3 601 drives the aluminum sheet coil 9 to unwind, it can be continuously and slowly rotated so that the unwound coil is slowly accumulated. First, the motor 1 410 drives the extrusion conveyor belt 407 and the clamping bar 409 to rotate. When the clamping bar 409 translates downward, it can drive the coil to translate on the surface of the table board 1 through the clamping cooperation with the translation conveyor belt 303. When the clamping bar 409 moves upward, the coil is not driven by the clamping force and stops. At the same time, the distance sensor 11 detects the distance change and controls the digital display controller 10 to drive the hydraulic cylinder 701 to extend. The downward pressure process of the hydraulic cylinder 701 is a one-stage downward pressure. The rising process of the pressure cylinder 701 is divided into two stages. During the downward pressure process, the pressure plate 704 can be fixed against the surface of the coil after a small amount of extension. As the hydraulic cylinder 701 is fully extended, the beveled blade cutter 702 can cut the coil. During the rising process, the beveled blade cutter 702 first rises to above the cutting groove 703 (at this time, the pressure plate 704 continues to press down and fix the coil), and at this time, the pressure plate 704 contacts the coil to avoid inertial retraction of the coil and avoid data deviation. After the distance sensor 11 rotates one circle with the clamping strip 409 and contacts the surface of the coil again, the hydraulic cylinder 701 drives the beveled blade cutter 702 and the pressure plate 704 to rise in two stages. At the same time, the two conveying rollers 803 rotate to convey the cut aluminum plate to the rear (the speed of the conveying roller 803 is faster than that of the fixed roller 402), and then the new coil is moved to the bottom of the beveled blade cutter 702 again, and so on and so forth to complete automatic fixed-length slitting.

[0034] Reference Figure 4 As shown, the translation structure 3 includes four ear plates 301 fixedly connected to the bottom surface of the table top 1, and the four ear plates 301 are respectively located at the four corners of the hollow groove 2, and a translation roller 302 is rotatably connected between every two ear plates 301, and the two translation rollers 302 are connected by a translation conveyor belt 303. The lower side of the hollow groove 2 is fixedly connected with a support plate 304 through a connecting plate, and the support plate 304 abuts against the upper inner wall of the translation conveyor belt 303. When the clamping bar 409 abuts against the surface of the coil, the translation conveyor belt 303 is squeezed. Under the support of the support plate 304, the translation conveyor belt 303 can achieve clamping cooperation with the clamping bar 409 and can smoothly drive the coil to move. At this time, the translation conveyor belt 303 can rotate with it.

[0035] As an optional embodiment, the extrusion drive structure 4 includes two L-shaped support rods 401, two adjustment blocks 403 and two linkage arms 405, one side of the two L-shaped support rods 401 is rotatably connected with a fixed roller shaft 402, and a motor 410 for driving the fixed roller shaft 402 to rotate is fixedly installed on the outer wall of one of the L-shaped support rods 401, the lower ends of the two linkage arms 405 are rotatably connected to the two ends of the shaft of the fixed roller shaft 402, the upper ends of the two linkage arms 405 are rotatably connected with a tensioning roller shaft 406, the two adjustment blocks 403 are rotatably connected with an adjustment roller shaft 404, and the fixed roller shaft 402, the tensioning roller shaft 406 and the adjustment roller shaft 404 are connected by the extrusion conveyor belt 4 07 transmission connection, both sides of the surface of the table top 1 are provided with an adjustment positioning structure 5 for fixing the position of the adjustment block 403, the surface of the extrusion conveyor belt 407 is fixedly connected with a clamping bar 409 abutting against the upper surface of the translation conveyor belt 303, and the coil passes through the clamping bar 409 and the translation conveyor belt 303. When the motor 410 rotates, it can drive the extrusion conveyor belt 407 to rotate continuously. When the clamping bar 409 rotates to the bottom and translates, it can drive the coil to move by cooperating with the translation conveyor belt 303. When the clamping bar 409 moves to the adjustment roller 404 and then rises, the distance between the distance sensor 11 on its surface and the surface of the coil changes, and sends an electrical signal to the digital display controller 10.

This is not repeated here), the output end of the digital display controller 10 is electrically connected to the motor 1 410, the bolt fixing part includes a bolt hole 506 opened on the sliding sleeve 505, and a bolt 507 is threadedly connected in the bolt hole 506, and a plurality of positioning holes 508 plugged with the bolt 507 are opened on the sliding rod 2 504. When it is necessary to adjust the length of the aluminum plate cut each time, the two adjustment blocks 403 are moved at the same time, so that the sliding rod 1 501 slides in the sliding rod hole 502, and the sliding sleeve 505 slides on the sliding rod 2 504 (during the movement, the extrusion conveyor belt 407 drives the tensioning roller 406 to move downward, and at this time the linkage arm 405 rotates downward and drives the tension spring 408 to stretch elastically). After the sliding sleeve 505 moves to a suitable position, the bolt 507 is inserted into the bolt hole 506 and rotated until it is inserted into the positioning hole 508, thereby completing the position fixation of the sliding sleeve 505, and the distance sensor 11 can detect whether the clamping bar 409 is in contact with the surface of the coil.

Two collars 705 are fixedly connected to the upper ends of the two side walls of the beveled blade cutter 702. Two vertical rods 706 mounted with the collars 705 are fixedly connected to the upper surface of the pressure plate 704. A spring 707 is connected between the collars 705 and the pressure plate 704, and the spring 707 is mounted on the outside of the vertical rod 706. When the control hydraulic cylinder 701 is extended, its output end drives the beveled blade cutter 702 to move downward. Since its cutting edge is inclined, it After contacting the edge of the cutting groove 703, the plate can be cut smoothly. As the beveled blade cutter 702 moves down and up, the two grinding strips 708 on its surface can grind the cutting part of the plate. When the beveled blade cutter 702 moves down a small distance, the two pressing plates 704 abut against the surface of the coil. As the beveled blade cutter 702 continues to move down, under the elastic force of the compression spring 707, the two pressing plates 704 can respectively press down and fix the coils on both sides of the beveled blade cutter 702, so that the cutter can be cut. The cutting is more accurate and smooth, and the smooth grinding of the cutting part can be ensured. When the clamping bar 409 is not in contact with the surface of the coil, the beveled blade cutter 702 can be partially raised.

At the same time, due to the close abutment between the two conveying rollers 803, the edge bending part of the aluminum plate (caused by shearing action or other reasons) can be rolled and flattened.

The fixed triangular support plate 603 and the movable triangular support plate 609 can drive the top support plate 16 and the aluminum sheet coil 9 to rotate by being engaged with the engaging groove 605. Through the design of the two top support plates 16, the aluminum sheet coil 9 can be stably fixed while the sling for lifting the aluminum sheet coil 9 can be easily removed.

[0040] Furthermore, a threaded rod 604 is fixedly connected to the fixed triangular support plate 603, and a through hole 608 which is sleeved with the threaded rod 604 is penetrated through the middle of the movable triangular support plate 609 and the circular plate 602, and the end of the threaded rod 604 is threadedly connected to a nut 607 for squeezing the movable triangular support plate 609 to move toward the fixed triangular support plate 603, and a bearing 606 is fixedly connected to the circular plate 602 at the movable triangular support plate 609, and the other support plate 15 is thickened, and the upper end is an arc surface abutting against the outer wall of the bearing 606, when the two top support fixing plates 16 are sleeved on the outside of the threaded rod 604 together with the aluminum plate coil 9, the two engaging grooves 605 at one end of the two top support fixing plates 16 abut against the two sides of the fixed triangular support plate 603, and then the movable triangular support plate 609 is sleeved on the end of the threaded rod 604 through the through hole 608. , so that the inclined surfaces on both sides of the movable triangular support plate 609 are in contact with the two engaging grooves 605 at the other end of the two support top fixing plates 16, and then the nut 607 is rotated at the end of the threaded rod 604.

[0041] Working principle of the present invention:

[0042] First, insert the two top support fixing plates 16 into the middle hole of the aluminum sheet coil 9, then sleeve the aluminum sheet coil 9 and the two top support fixing plates 16 together on the threaded rod 604, and then drive the movable triangular support plate 609 to move toward the fixed triangular support plate 603, drive the two top support fixing plates 16 to expand outwards in the middle hole of the coil to complete the fixation of the aluminum sheet coil 9, and then pull the coil from the bottom to make it abut against and bypass the top of the guide roller 12, and pass through the clamping strip 409 and the translation conveyor belt 303; between the two pressure plates 704 and the table board 1; between the two conveying rollers 803;

[0043] Then, the digital display controller 10 controls the motor 3 601 to drive the aluminum sheet coil 9 to unwind.

[0044] After the clamping bar 409 rotates one circle, it contacts the surface of the coil again, and drives the coil to be transported to a fixed distance below the oblique blade cutter 702 again. This reciprocating process can achieve automatic fixed-length slitting.

[0045] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
