Description

Technical Field

[0001] The present invention mainly relates to the technical field of positioning and deviation correction, and in particular to a positioning and deviation correction device for a punching feeder. Background Art

[0002] In the field of metal stamping, the large-scale production of steel boxes (such as logistics turnover boxes) places higher demands on the feeding accuracy of metal strip. Steel boxes are typically manufactured from cold-rolled or galvanized steel sheets with a thickness of 1.5-5mm, and are completed through processes such as stamping, bending, and welding. Lateral deviation of the metal strip during the feeding process can lead to hole misalignment or edge burrs in components such as the side panels and bottom panel of the steel box. Vertical warping can cause arc deformation in the stamped parts, affecting the accuracy and sealing of the joints during box assembly. Therefore, positioning and correction devices have become a critical link in ensuring product quality in automated steel box production lines.

[0003] Traditional correction devices mostly only correct the lateral deviation of the metal strip, such as achieving lateral positioning through the use of side wheels or cylinders. However, they cannot solve the problem of vertical warping of the metal strip caused by rolling stress and uneven conveying tension, which causes the metal strip to be non-parallel to the working surface of the stamping die, affecting the stamping accuracy.

[0004] Some devices use a single-side drive to correct the web, such as a single cylinder pushing a single-sided stop wheel. This creates uneven force on both sides of the metal strip during correction, which can easily lead to strip distortion or secondary deviation. Alternatively, multiple sets of correcting wheels operate asynchronously, preventing simultaneous contact between both sides of the metal strip, impacting the corrective effect. Some high-end correcting devices utilize closed-loop control with servo motors and sensor feedback. However, these devices are complex, costly, require extremely precise installation, and are difficult to maintain, making them difficult to adopt for small and medium-sized stamping companies.

[0038] Example:

[0039] Refer to the attached Figures 1 to 11 A positioning and correcting device for a stamping feeder includes a frame 2 arranged on one side of a stamping machine 1, the frame 2 includes vertical plates 21 arranged symmetrically on the left and right, and a top plate 22 is mounted on the upper ends of the two vertical plates 21. A feeding mechanism 3 is provided on the frame 2, and the feeding mechanism 3 is used to convey a metal strip 4 to the stamping machine 1. A vertical correcting device 5 is provided on the top plate 22, and a horizontal correcting device 6 is provided between the two vertical plates 21. The vertical correcting device 5 is used to adjust the position of the metal strip 4 in the vertical direction, and the horizontal correcting device 6 is used to correct the horizontal position of the metal strip 4.

[0040] The feeding mechanism 3 includes a feed roller 1 31 and a feed roller 2 32 rotatably mounted between two vertical plates 21. The roller surfaces of the first and second feed rollers 31 and 32 are parallel and arranged at the same height. A lateral deviation correction device 6 is positioned between the first and second feed rollers 31 and 32. One end of the mounting shaft of the first feed roller 31 is connected to a motor 33, which is fixed to the outer wall of the vertical plate 21. The other end of the mounting shaft of the first feed roller 31 extends beyond the vertical plate 21 and is connected to a sprocket 1 34. A sprocket 2 35 is mounted on the mounting shaft of the second feed roller 32. The sprockets 1 34 and 35 are connected via a chain drive. The chain drive between the first and second feed rollers 31 and 32 ensures consistent conveying speeds and prevents slippage of the metal belt.

[0041] The lateral correction device 6 includes a support mechanism 61, and a fixed plate 63 is fixedly arranged at the center of the support mechanism 61. Six "convex" guide grooves 65 are opened at equal angles on the fixed plate 63. Among them, movable frames 1 62 are slidably installed in two guide grooves 65 perpendicular to the conveying direction of the feeding mechanism 3, and movable frames 2 67 are slidably installed in the remaining guide grooves 65. Correction wheels 64 are rotatably installed on the movable frames 1 62 and 2 67 through wheel frames 66. The movable frames 1 62 and 2 67 slide synchronously along their respective guide grooves 65, so that the correction wheels 64 installed thereon can be close to the two side surfaces of the metal belt 4 at the same time.

[0042] A drive disk assembly 8 is rotatably provided on the support mechanism 61. The drive disk assembly 8 is arranged on the outside of the fixed disk 63. The drive disk assembly 8 includes a turntable 81. A center groove 82 is opened at the center of the turntable 81. The fixed disk 63 is concentrically arranged in the center groove 82. Six drive grooves 83 are opened at equal distances on the turntable 81. The drive grooves 83 are arranged at an angle. A follower 84 is installed at the lower end of the movable frame 1 62 and the movable frame 2 67. The follower 84 is movably installed in the drive groove 83.

[0043] Each drive slot 83 is provided with a stopper 85 at its upper end. A clearance groove 86 is defined on the stopper 85 to allow clearance for the connecting shaft of the follower 84. Furthermore, the clearance groove 86 allows the connecting shaft of the follower 84 to slide only within a limited range, preventing the follower 84 from falling out of the drive slot or excessive movement of the movable frame, which could cause the metal belt to be pinched.

[0044] The driving disk assembly 8 is connected to the driving mechanism 7, which is used to drive the turntable 81 to rotate. The driving mechanism 7 includes a linear module 71 fixed on the inner wall of a vertical plate 21. A moving block 72 is fixedly provided on the output end of the linear module 71. The moving block 72 is rotatably connected to the connecting rod 73 through a pin shaft 74. The other end of the connecting rod 73 is rotatably connected to the turntable 81 through another pin shaft 74.

[0045] The support mechanism 61 includes a support column 611, a base plate 612 fixedly mounted on the upper end of the support column 611, and a limit ring 613 disposed on the upper end of the base plate 612. A connecting plate 87 is fixedly mounted on the lower end of the turntable 81 via angle iron. The lower end of the connecting plate 87 is provided with a limit ring groove 88 that mates with the limit ring 613. The limit ring 613 of the support mechanism 61 mates with the limit ring groove 88 of the connecting plate 87 to ensure the coaxiality of the turntable 81 during rotation.

[0046] There are two vertical correcting devices 5, which are respectively arranged above the feed roller 1 31 and the feed roller 2 32. The vertical correcting device 5 includes a mounting frame 51, on which a pressure roller 52 is rotatably mounted, and a hydraulic cylinder 53 is fixedly mounted on the top plate 22. The piston rod of the hydraulic cylinder 53 extends out of the top plate 22 and is connected to the mounting frame 51. A linear bearing 54 is provided on the top plate 22. A guide rod 55 is fixedly mounted on the upper end of the mounting frame 51, and the guide rod 55 is slidably mounted in the linear bearing 54 up and down.

[0047] Working principle:

[0048] Motor 33 starts, rotating feed roller 1 31. This, in turn, is driven by sprocket 1 34, a chain, and sprocket 2 35, which in turn causes feed roller 2 32 to rotate synchronously. The surfaces of feed roller 1 31 and feed roller 2 32 are parallel and of equal height, forming a conveying channel for the metal strip 4. The metal strip 4 is fed into the punching machine 1 under the action of friction.

[0049] The piston rod of the hydraulic cylinder 53 is in the initial position, and a certain gap or slight contact is maintained between the pressure roller 52 and the feed roller 1 31 or the feed roller 2 32 to ensure that the metal strip 4 can pass smoothly.

[0050] Working process of vertical correction device 5:

[0051] When the metal belt 4 is offset in the vertical direction (up and down), the piston rod of the hydraulic cylinder 53 is extended and retracted, driving the mounting frame 51 to move up and down. The guide rod 55 slides in the linear bearing 54 to ensure the vertical movement of the mounting frame 51 and prevent shaking.

[0052] The pressure roller 52 moves up and down with the mounting frame 51, applying vertical pressure to the metal strip 4 by adjusting the spacing between it and the first or second feed rollers 31 and 32. If the metal strip deviates upward, the hydraulic cylinder 53 pushes the pressure roller 52 downward, pressing the metal strip back to a horizontal position. If it deviates downward, the hydraulic cylinder 53 retracts, reducing the pressure on the pressure roller and ensuring that the metal strip remains in a horizontal state.

[0053] Working process of the lateral deviation correcting device 6:

[0054] The driving mechanism 7 is operated by activating the linear module 71, which drives the moving block 72 to reciprocate along a straight line. The moving block 72 drives the connecting rod 73 to swing through the pin 74, forming a crank slider mechanism, which in turn drives the rotating disk 81 to rotate around the central axis of the fixed disk 63.

[0055] When the turntable 81 rotates, the inclined driving groove 83 pushes the follower 84 to move in the driving groove 83, thereby driving the movable frame 1 62 and the movable frame 2 67 to slide along the guide groove 65. Figure 10The figure shows the initial state of the movable frame 1 62 and the movable frame 2 67. At this time, the correcting wheel 64 is away from the metal belt 4. After the drive mechanism 7 drives the turntable 81 to rotate, the driving groove 83 is tilted. The driving groove 83 is a straight groove. The distances from the two ends of the driving groove 83 to the center of the fixed disk 63 are unequal. As the turntable 81 rotates, the position of the driving groove 83 changes radially relative to the center. In this embodiment, when the turntable 81 rotates clockwise, the tilt direction of the driving groove 83 causes the follower 84 to move toward the center of the fixed disk 63, as shown in FIG. Figure 11 The figure shows the state of the movable frame 1 62 and the movable frame 2 67 approaching the metal belt 4 after the turntable 81 rotates clockwise. On the contrary, when the turntable 81 rotates counterclockwise, the follower 84 moves away from the center of the fixed disk. Figure 10 and Figure 11 The wheel frame 66 and the correcting wheel 64 are omitted. When the follower 84 slides within the drive slot 83, it converts the circular motion of the turntable 81 into linear sliding motion of the movable frame 1 62 and the movable frame 2 67. The inclination angle of the drive slot 83 determines the radial movement of the follower 84, which in turn is converted into the lateral sliding distance of the movable frames 1 62 and 2 67, thereby adjusting the spacing of the correcting wheels 64.

[0056] The wheel frames 66 on the movable frame 1 62 and the movable frame 2 67 are installed at different positions. By adjusting the positions of the correcting wheels 64 on the movable frame 1 62 and the movable frame 2 67, the correcting wheels 64 can be close to both sides of the metal belt 4 at the same time. The specific position of the correcting wheels 64 is controlled by the width of the metal belt 4.

[0057] The movable frame 1 62 in the two guide slots 65 perpendicular to the conveying direction moves left and right toward the sides of the metal belt 4. The movable frame 2 67 in the remaining four guide slots 65 moves along the diagonal guide slots 65, ultimately bringing all the corrective wheels 64 into contact with both sides of the metal belt 4 simultaneously. A stopper 85 at the upper end of the drive slot 83 restricts the upward movement of the follower 84, ensuring the positional accuracy of the corrective wheels 64. The avoidance slot 86 also prevents the movement of the follower 84.

[0058] When the metal belt 4 deviates laterally, the rotation of the turntable 81 pushes the correcting wheels 64 through the drive slots 83 to apply pressure toward the deviated side, forcing the metal belt 4 back to the conveyor centerline. Because the six correcting wheels 64 operate synchronously, they evenly apply pressure to both sides of the metal belt, creating a multi-directional clamp and preventing deformation caused by unilateral force.

[0059] Feeding stage: Motor 33 drives the feed roller assembly to convey the metal strip 4, while the drive disc assembly 8 of the lateral deviation correction device 6 is in standby mode. When the sensor detects that the metal strip 4 has a lateral or vertical deviation, the drive mechanism 7 and the vertical deviation correction device 5 are activated.

[0060] In the transverse direction, turntable 81 rotates, driving the correcting wheels 64 to move synchronously, squeezing the sides of the metal strip to align it. In the vertical direction, pressure roller 52 moves up and down to adjust the levelness of the metal strip. Cyclic calibration: After correcting the deviation, drive mechanism 7 resets and waits for the next deviation detection, achieving continuous dynamic calibration.

[0061] The lateral correction device 6 is arranged between the feed roller 1 31 and the feed roller 2 32 to ensure that the metal strip is corrected in time during the conveying process; the vertical correction device 5 is located above the feed roller to adjust the vertical position in real time.

[0062] The above-mentioned embodiments only express a certain implementation method of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent of the present invention shall be based on the attached claims.
