Description

Technical Field

[0001] This invention relates to the field of plate rolling machine technology, specifically a four-roller intelligent fully CNC bending production line unit. Background Technology

[0002] A plate rolling machine can roll a straight plate into a plate with the required curvature. The plate rolling machine uses external forces such as hydraulic pressure and mechanical force to make the working rollers move, thereby bending or rolling the plate into shape. Depending on the rotation and position changes of the working rollers of different shapes, it can process parts such as elliptical parts, arc parts, and cylindrical parts.

[0003] The shortcomings of existing technology: When unloading irregularly curved sheets, they are usually held in place by an electromagnet chuck. However, due to the inconsistent curvature of the inner side of the irregularly curved sheet, the electromagnet chuck's hold on the coil is unstable and prone to falling. Furthermore, the hold position cannot be guaranteed to be at the center of gravity of the coil, resulting in uneven force distribution. This requires greater lifting and holding forces, increasing energy consumption and potentially damaging the electromagnet chuck. Additionally, the sheets are often stacked together before processing. When lifting the upper sheet, adjacent sheets tend to attract each other. Although the next sheet may not be completely lifted, the attraction may cause it to shift or even fall, affecting subsequent lifting attempts. Summary of the Invention

[0004] The purpose of this invention is to provide a four-roller intelligent fully CNC bending production line unit to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a four-roller intelligent fully CNC bending production line unit, including a fixed frame and a plate rolling machine located at the lower end of the fixed frame, wherein an automatic feeding area and an automatic unloading area are respectively provided on both sides of the plate rolling machine at the lower end of the fixed frame; The automatic feeding area is equipped with a board storage rack for storing boards to be processed, a pushing mechanism for correcting the boards and conveying them to the board rolling machine, and a transfer mechanism for transferring the boards from the board storage rack to the pushing mechanism.

[0010] As a further improvement of the present invention, both the first longitudinal moving component and the second longitudinal moving component include a mounting base and a drive motor. The lower end face and the side face of the mounting base are provided with sliding grooves that are slidably connected to the slide rails provided on the first moving beam and the second moving beam. The drive motor is mounted on the mounting base, and the output end of the drive motor is connected to the racks provided on the first moving beam and the second moving beam through a gear.

[0011] As a further improvement of the present invention, both the first Y-axis moving component and the second Y-axis moving component include a lifting motor and a lifting column. The lifting motor is disposed on the side of the mounting base, and the lifting column is slidably connected to the mounting base. The lifting motor and the lifting column are connected by a gear and rack transmission. The mounting bracket and the electromagnet suction block are disposed at the lower end of the lifting column.

[0012] As a further improvement of the present invention, both the sheet metal storage rack and the molded product storage rack include two parallel support frames, and a plurality of inclined baffles are provided on one side and one end of the support frames.

[0013] As a further improvement of the present invention, auxiliary mechanisms for conveying and correcting are provided on both sides of the support frame near the end of the plate rolling machine, and the auxiliary mechanisms include: A guide rail is mounted on a support frame, and a sliding seat is slidably connected to the guide rail. A limit wheel is rotatably mounted on the sliding seat. A cylinder is disposed on one side of the support frame, and the output end of the cylinder is connected to a sliding seat.

[0014] This invention also provides a manufacturing process for a four-roller intelligent fully CNC bending production line unit, which includes the following steps: S1. Automatic feeding: The sheet material to be rolled is stacked on the sheet material storage rack. Then, the bidirectional motor is started, which drives the transmission shaft to move, thereby realizing the second moving crossbeam to move horizontally on the upper end of the fixed frame. After the second moving crossbeam and the center line of the sheet material are in the same vertical direction, the bidirectional motor stops moving. The drive motor is started, which drives the mounting base to move on the second moving crossbeam. After aligning the electromagnet block with the center of the sheet material, the drive motor stops moving. The lifting motor is started, which drives the lifting column to move downward until the electromagnet block attracts the center of the sheet material. Then, the bidirectional motor, drive motor and lifting motor move synchronously. The electromagnet block drives the sheet material to move along the inclined straight line, so that one side of the sheet material contacts the inclined baffle. The inclined baffle scrapes off the sheet material stuck to the lower end of the sheet material, and then it is hoisted to the pushing mechanism. The transfer mechanism then transfers the next sheet material. In the process of scraping off the board, the distance that the lifting motor drives the electromagnet block to move upward is z, the distance that the drive motor drives the electromagnet block to move upward is y, and the distance that the bidirectional motor drives the electromagnet block to move upward is x. y is greater than or equal to half the width of the board, x is greater than or equal to half the length of the board, and z is the same as the height of the inclined baffle. S2, Sheet rolling: The pushing device limits one end of the sheet, and then pushes the sheet towards the rolling machine. During this process, the sheet is calibrated by the calibration device and auxiliary mechanism, and then rolled into a sheet with different curvature by the rolling machine. S3. Coil Unloading: Start the bidirectional motor of the unloading conveyor mechanism and simultaneously start the transfer mechanism to perform the loading operation. The bidirectional motor drives the transmission shaft to move. After the first moving crossbeam moves to a suitable position, the bidirectional motor stops moving. Start the drive motor. The drive motor drives the mounting base to move to a designated position on the first moving crossbeam and then stops moving. Start the lifting motor. The lifting motor drives the lifting column to move downward. Then, the servo motor drives the electromagnet chuck to rotate at a certain angle to align with the center of gravity of the coil. Then, the bidirectional motor works to make the electromagnet chuck hold the coil. The bidirectional motor, drive motor and lifting motor move synchronously to place the finished coiled sheet with different curvature on the molded product storage rack, and then transport it to the stacking table and connect it to the automatic welding line for welding processing.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the automatic feeding area is equipped with a board storage rack for storing boards to be processed, a pushing mechanism for correcting the boards and conveying them to the rolling machine, and a transfer mechanism for transferring the boards from the board storage rack to the pushing mechanism. The automatic unloading area is equipped with a shaped product storage rack for placing the rolled boards and an unloading conveying mechanism for automatic unloading. A servo motor is provided on one side of the mounting frame, and the rotating shaft of the servo motor is movably mounted on the mounting frame. The output end of the servo motor is equipped with an electromagnet chuck through a connecting frame. When the electromagnet chuck adsorbs the rolled board, its adsorption angle and position can be flexibly adjusted. It can appropriately adjust the suction position during unloading according to the center of gravity position of the board with different curvature, prevent the rolled material from falling off, reduce unloading energy consumption, improve the service life of the unloading structure, and realize the automated operation of loading, rolling and unloading, effectively improving the rolling efficiency and reducing the burden on the workers. 2. In this invention, when lifting the board, the bidirectional motor, drive motor, and lifting motor move synchronously. The electromagnet pull block drives the board to move along a diagonal straight line, so that one side of the board contacts the inclined baffle. The inclined baffle scrapes off the board that is stuck to the bottom of the board. The upward movement distance z is the same as the height of the inclined baffle. The drive motor drives the electromagnet pull block to move a distance y that is greater than or equal to half the width of the board. The bidirectional motor drives the electromagnet pull block to move a distance x that is greater than or equal to half the length of the board. Through the diagonal upward movement combined with the obstruction of the inclined baffle, the contact area between the two boards is gradually reduced, thereby reducing the attraction between the two boards. The board is then completely lifted when the contact area between the two boards is less than one-quarter. When the upper plate grabs the board, it prevents the next board from sticking and causing the position to shift, which would affect the next loading. Attached Figure Description

After the plate rolling machine 2 completes the rolling of the plate with different curvature, the mounting frame 74 is moved to a suitable position by the first moving crossbeam 71, the first longitudinal moving component 72, and the first Y-axis moving component 73. Then, the servo motor 75 drives the electromagnet chuck 76 to rotate at a suitable angle to hold the plate.

The drive motor 722 drives the mounting base 721 to move on the second moving crossbeam 51. After aligning the electromagnet suction block 54 with the center of the sheet material, it stops moving. The lifting motor 731 is started. The lifting motor 731 drives the lifting column 732 to move downward until the electromagnet suction block 54 attracts the center of the sheet material. Then, the bidirectional motor 81, drive motor 722 and lifting motor 731 move synchronously. The electromagnet suction block 54 drives the sheet material to move along the inclined straight line direction, so that one side of the sheet material contacts the inclined baffle 32. The inclined baffle 32 scrapes off the sheet material stuck to the lower end of the sheet material. Then, it is hoisted to the pushing mechanism 4.

9. The production process of the four-roller intelligent fully CNC bending production line unit according to claim 8, characterized in that: This production process includes the following steps: S1. Automatic feeding: The sheet material to be rolled is stacked on the sheet material storage rack (3), and then the bidirectional motor (81) is started. The bidirectional motor (81) drives the transmission shaft (82) to move, thereby realizing the second moving crossbeam (51) moving horizontally on the upper end of the fixed frame (1). After the second moving crossbeam (51) and the center line of the sheet material are in the same vertical direction, the bidirectional motor (81) stops moving and the drive motor (722) is started. The drive motor (722) drives the mounting base (721) to move on the second moving crossbeam (51) to align the electromagnet suction block (54) with the center of the sheet material. After stopping the movement, the lifting motor (731) is started. The lifting motor (731) drives the lifting column (732) to move downward until the electromagnet block (54) attracts the center of the plate. Then the bidirectional motor (81), the drive motor (722) and the lifting motor (731) move synchronously. The electromagnet block (54) drives the plate to move in the oblique straight direction, so that one side of the plate contacts the oblique baffle (32). The oblique baffle (32) scrapes off the plate stuck to the bottom of the plate and then lifts it to the pushing mechanism (4). The transfer mechanism (5) then transfers the next plate. In the process of scraping off the board, the lifting motor (731) drives the electromagnet block (54) to move upward a distance of z, the drive motor (722) drives the electromagnet block (54) to move a distance of y, and the bidirectional motor (81) drives the electromagnet block (54) to move a distance of x. y is greater than or equal to half the width of the board, x is greater than or equal to half the length of the board, and z is the same height as the inclined baffle (32). S2, Plate rolling: The pushing device (44) limits one end of the plate and then pushes the plate to move towards the plate rolling machine (2). During this process, the plate is calibrated by the calibration device (43) and the auxiliary mechanism (9), and then rolled into a plate with different curvature by the plate rolling machine (2). S3. Coil unloading: Start the bidirectional motor (81) of the unloading conveyor mechanism (7), and simultaneously start the transfer mechanism (5) to perform the plate loading operation. The bidirectional motor (81) drives the transmission shaft (82) to move. After the first moving crossbeam (71) moves to a suitable position, the bidirectional motor (81) stops moving. Start the drive motor (722). The drive motor (722) drives the mounting base (721) to move to the designated position on the first moving crossbeam (71) and then stops moving. Start the lifting motor (731). The lifting motor (731) drives the lifting column (732) to move downwards. Then the servo motor (75) drives the electromagnet chuck (76) to rotate at a certain angle to align with the center of gravity of the roll material. Then the bidirectional motor (81) works to make the electromagnet chuck (76) hold the roll plate. The bidirectional motor (81), the drive motor (722) and the lifting motor (731) move synchronously to place the rolled material with different curvature on the molded product storage rack (6) and then transport it to the stacking table and connect it to the automatic welding line for welding processing.
