Description

Technical Field

[0001] The invention relates to the technical field of metal shaping, in particular to a shaping fixture used for processing metal plates. Background Art

[0002] A fixture is a device used to secure a workpiece in the correct position during machining or testing. Broadly speaking, any device used to quickly, conveniently, and safely secure a workpiece during any process can be called a fixture.

[0003] Currently, many plate products require shaping before machining to achieve the required flatness. Current shaping methods are broadly categorized as bench shaping and heat treatment (heat leveling). Bench shaping (cold working): Bench workers hammer the product blank with tools like hammers to ensure the product's flatness meets the requirements for subsequent machine tool processing. This shaping method is labor-intensive and inefficient. Heat treatment (heat leveling): While this method works well for large-volume production, prototypes and small batches require heat treatment tooling and post-heat treatment material analysis, resulting in high production costs.

[0004] For example, a metal plate shaping fixture disclosed in publication number CN205270433U, through the structural coordination between the support frame and the column frame, a shaping device is installed on the hanger and then used in conjunction with the slide on the support frame, thereby realizing the shaping of the metal plate. However, in the actual processing and production process, after the workpiece is clamped, if the deformation of the shaped workpiece is too large when pressed down, the two sides of the clamped metal part tend to translate outward. However, after the above-mentioned shaping fixture clamps the clamped workpiece, the clamping part cannot move, which will cause extrusion damage to the servo motor or the lead screw. Even after the shaping and pressing, the metal plate cannot be well repaired. When the deformation is too large, the metal plate may even be pressed down into a W shape, which is not conducive to the shaping and repair work of the metal plate. In view of this, a shaping fixture for metal plate processing is proposed. Summary of the Invention

[0020] Compared with the prior art, the present invention provides a shaping fixture for metal plate processing, which has the following beneficial effects:

[0021] 1. The shaping fixture for metal plate processing is used in conjunction with a U-shaped plate, Hall sensor 1 and Hall sensor 2. During the process of pressing and shaping the metal plate, the pressure spring plays a supporting and pressure-bearing role.

[0022] 2. The shaping fixture for metal plate processing is provided with a limit mechanism. In the process of clamping and fixing the metal plate to be shaped, the clamp mechanism as a whole moves toward the metal plate. During the movement, the metal plate supports and moves the clamp mechanism. In the process of the convex connecting frame moving toward the triangular extrusion body, the triangular extrusion body squeezes the movable clamp body and causes the movable clamp body to move downward, thereby achieving stable clamping of the metal plate in both vertical and horizontal directions, thereby ensuring the stability of the shaping process.

[0023] 3. The shaping fixture for metal plate processing is provided with a limiting mechanism. During the process of clamping the metal plate, the convex connecting frame moves toward the triangular extrusion body, and the convex connecting frame and the triangular extrusion body undergo relative displacement. The transmission rack drives the transmission gear to rotate counterclockwise, and the movable rod is continuously moved. Under the limiting action of the convex plate and the limiting column, when the convex connecting frame and the triangular extrusion body no longer undergo relative displacement, the convex connecting frame remains stationary under the limit of the transmission gear, thereby ensuring the overall stability of the equipment during the shaping process.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Figures 1-6As shown, the present invention provides a technical solution: a shaping fixture for processing metal plates, comprising a support frame 1 and support legs 7, support legs 7 are welded at the four corners of the support frame 1, two groups of slide grooves 2 are fixed on the side walls on both sides of the support frame 1, a shaping mechanism 3 is provided on the support frame 1, the shaping mechanism 3 includes a fixing frame 32, the fixing frame 32 is fixed on the side walls on both sides of the support frame 1, and a cylinder 2 31 is fixedly installed on the fixing frame 32, a leveler 33 is welded at the output end of the cylinder 2 31, and under the transmission action of the cylinder 2 31, the leveler 33 extrude and shape the workpiece below. A stabilizing clamp mechanism 6 is slidably installed between the two groups of slide grooves 2. Two groups of stabilizing clamp mechanisms 6 are symmetrically arranged. A servo motor 5 is fixed on the side wall of the support frame 1. The servo motor 5 drives the stabilizing clamp mechanism 6 to move. The stabilizing clamp mechanism 6 includes: a movable truss 61, a bottom connecting plate 62, a cylinder 1 63, a support plate 64, a U-shaped plate 611, a Hall sensor 1 612 and a Hall sensor 2 613. By using the U-shaped plate 611, Hall sensor 1 612 and Hall sensor 2 613 in combination, during the process of pressing and shaping the metal plate, the pressure spring 6554 plays a supporting and pressure-bearing role. When it is greater than its own rated pressure range, the magnet 614 will move from the position of Hall sensor 1 612 to the direction of Hall sensor 2 613. The PCL controller controls the servo motor 5 to drive the screw rod 4, so that the two sets of clamp mechanisms 6 move away from each other, thereby realizing subsequent shaping of the metal plate, avoiding impact damage to the screw rod 4 and the servo motor 5 during the shaping process, and improving the shaping efficiency and service life of the equipment.

[0034] Among them, a rectangular cavity is opened on the movable truss 61, and a supporting clamp 65 is arranged in the rectangular cavity. The supporting clamp 65 includes a convex connecting frame 651, and the convex connecting frame 651 is slidably installed in the rectangular cavity. A rectangular opening 1 is opened on the right side wall of the convex connecting frame 651, and a movable clamp 652 is slidably installed in the rectangular opening 1. A fixed clamp 653 is welded on the side wall of the rectangular opening 1. The movable clamp 652 is located on the side wall of one end of the convex connecting frame 651 and an inclined surface is provided, and a triangular transmission mechanism 655 is attached to the inclined surface of the movable clamp 652. A limiting mechanism 656 for limiting its position is provided above the triangular transmission mechanism 655.

[0035] It is worth noting that the bottom connecting plate 62 is welded to the side wall of the bottom of the movable truss 61. A screw 4 is threaded through and connected to the bottom connecting plate 62, and is welded to the output end of the servo motor 5. The support plate 64 is welded to the side wall of the movable truss 61. Cylinder 1 63 is welded to the side wall of the top of the movable truss 61. An L-shaped push rod 610 is fixed to the output end of cylinder 1 63. The U-shaped plate 611 is welded to the side wall of the movable truss 61. Hall effect sensors 1 612 and 2 613 are fixedly installed in the U-shaped plate 611 from right to left. The side of the movable clamp 652 away from the fixed clamp 653 is fixed to one end of a return spring 654, and the other end of the return spring 654 is fixed to the side wall of the convex connecting frame 651.

[0036] In addition, the triangular transmission mechanism 655 includes a triangular extrusion body 6551, and a rectangular opening 2 is opened on the side wall on the left side of the convex-shaped connecting frame 651. The side wall of the rectangular opening 2 is slidingly connected to the side wall of the top of the triangular extrusion body 6551. A limiting strip 6552 is welded to the top of the triangular extrusion body 6551. The limiting strip 6552 passes through the side wall on the left side of the convex-shaped connecting frame 651 and is slidingly connected to the side wall on the left side of the convex-shaped connecting frame 651. The left side wall of the triangular extrusion body 6551 is fixed to one end of the triangular connecting rod 6553, and the other end of the triangular connecting rod 6553 passes through the side wall of the movable truss 61 and is fixed to the side wall of the linkage rod 1 67. One end of the pressure spring 6554 is fixed to the left side wall of the triangular extrusion body 6551, and the other end of the pressure spring 6554 is fixed to the side wall of the rectangular cavity. The pressure spring 6554 is symmetrically arranged in two groups. The elastic system of the pressure spring 6554 is 2000-3000N / m. If the clamping force of the metal plate is set to 500N, when the pressure spring 6554 moves to the corresponding position, the magnet 614 moves to the position where the U-shaped plate 611 moves and places the Hall sensor 612 above. That is, when the clamping force of the metal plate reaches the rated set value, the magnet 614 and the Hall sensor 612 move to the same vertical direction. At this time, the servo motor 5 is controlled by the PCL controller and stopped to achieve automatic clamping of the metal plate. By setting a limiting mechanism 656, in the process of clamping and fixing the metal plate that needs to be shaped, the clamping mechanism 6 moves as a whole toward the metal plate. During the movement, the metal plate supports and pushes the clamping mechanism 6. In the process of the convex connecting frame 651 moving toward the triangular extrusion body 6551, the triangular extrusion body 6551 squeezes the movable clamping body 652 and causes the movable clamping body 652 to move downward, thereby achieving stable clamping of the metal plate in both vertical and horizontal directions, thereby ensuring the stability of the shaping process.

[0037] In this embodiment, the limiting mechanism 656 includes a limiting connecting rod 6561, one end of which is rotatably mounted with a movable rod 6564, and one end of the movable rod 6564 away from the limiting connecting rod 6561 is movably connected to a transmission gear 6563, and the transmission gear 6563 is rotatably connected to the rectangular cavity through a rotating shaft fixed at the axis. A rectangular through groove is provided on the side wall of the top of the triangular extrusion body 6551, and a transmission rack 6569 is fixed on the side wall of the rectangular through groove. The transmission rack 6569 is located below the transmission gear 6563 and meshes with the transmission gear 6563. A convex plate 6568 is fixed on the side wall of the movable rod 6564, and a limiting column 6565 is fixed on the side wall of the limiting connecting rod 6561. The side of the convex plate 6568 away from the limiting column 6565 is fixed to one end of the limiting spring 6566, and the other end of the limiting spring 6566 is fixed to the side wall of the column 6567, and the column 6567 is fixed to the side wall of the limiting connecting rod 6561. By setting a limiting mechanism 656, during the process of clamping the metal plate, the convex-shaped connecting frame 651 moves toward the triangular extrusion body 6551, and the convex-shaped connecting frame 651 and the triangular extrusion body 6551 are relatively displaced, the transmission rack 6569 drives the transmission gear 6563 to rotate counterclockwise, and the movable rod 6564 is continuously moved. Under the limiting action of the convex plate 6568 and the limiting column 6565, when the convex-shaped connecting frame 651 and the triangular extrusion body 6551 no longer undergo relative displacement, the convex-shaped connecting frame 651 remains stationary under the limitation of the transmission gear 6563, thereby ensuring the overall stability of the equipment during the shaping process.

[0038] In addition, a connecting spring 6562 is sleeved on the limiting connecting rod 6561, one end of the connecting spring 6562 is fixed to the outer wall of the convex connecting frame 651, and the other end of the connecting spring 6562 is fixed to the side wall of the fixed convex rod. The connecting spring 6562 is used to limit the position of the limiting connecting rod 6561, so that the movable rod 6564 and the transmission gear 6563 are always in a fit state, maintaining the limiting effect between the convex connecting frame 651 and the triangular extrusion body 6551, and the fixed convex rod is fixed on the outer wall of the limiting connecting rod 6561. The end of the limiting connecting rod 6561 away from the transmission gear 6563 passes through the side wall of the movable truss 61 and is fixed to the outer wall of the linkage rod 2 69. The linkage rod 2 69 is located below the linkage rod 1 67, and the transmission rod body 68 is fixed on the side wall of the linkage rod 1 67. Magnets 614 are fixed to both ends of the linkage rod 69 . The magnets 614 are located inside the U-shaped plate 611 and move inside the U-shaped plate 611 . A PCL controller for driving and controlling the servo motor 5 is mounted on the magnets 614 .

[0039] As an application of this embodiment:

[0040] First, place the metal plate to be processed on the support plate 64, start the servo motor 5, and drive the two sets of clamp mechanisms 6 to move toward each other through the screw rod 4.

[0041] When the two groups of clamp mechanisms 6 move to the point where the fixed clamp body 653 can support the metal plate, the plate body is manually moved and placed between the fixed clamp body 653 and the movable clamp body 652. During the movement, the metal plate supports and moves the clamp mechanism 6. When the convex connecting frame 651 moves toward the triangular extrusion body 6551, the triangular extrusion body 6551 squeezes the movable clamp body 652 and causes the movable clamp body 652 to translate downward, thereby achieving stable clamping of the metal plate in both the vertical and horizontal directions, ensuring the stability of the shaping process; at the same time, when the convex connecting frame 651 moves toward the triangular extrusion body 6551, the triangular extrusion body 6551 squeezes the movable clamp body 652 and causes the movable clamp body 652 to translate downward, thereby achieving stable clamping of the metal plate in both the vertical and horizontal directions, ensuring the stability of the shaping process.

[0042] After the fixed clamp 653 and the movable clamp 652 clamp the metal plate, the two sets of clamp mechanisms 6 will move toward each other. During this movement, the pressure spring 6554 will be compressed, and the triangular connecting rod 6553 and the movable truss 61 will be relatively displaced.

[0043] When the triangular connecting rod 6553 drives the linkage rod 2 69 and the magnet 614 to move to the position of the Hall sensor 1 612, it indicates that the clamping force on the metal plate has reached the rated set value. At this time, the PCL controller controls the servo motor 5 and stops the servo motor 5, and the two sets of clamp mechanisms 6 are in a static state. Then, the shaping mechanism 3 can perform the extrusion shaping process on the metal plate. During the shaping process, if the metal plate tends to shift on both sides due to the extrusion shaping, the pressure of the pressure spring 6554 increases. When the pressure of the pressure spring 6554 exceeds its rated pressure range, the magnet 614 will move from the position of the Hall sensor 1 612 to the direction of the Hall sensor 2 613. The PCL controller controls the servo motor 5 to drive the screw 4, so that the two sets of clamp mechanisms 6 move away from each other, and the metal plate is subsequently shaped. This avoids impact damage to the screw 4 and servo motor 5 during the shaping process, thereby improving the shaping efficiency and service life of the equipment. After the two sets of clamping mechanisms 6 move away from each other, the pressure of the pressure spring 6554 decreases, and the magnet 614 moves from the position of Hall sensor 2 613 to the direction of Hall sensor 1 612. The servo motor 5 is in an inoperative state, which can ensure the stability of the clamping of the metal plate.

[0044] After the shaping process is completed, start cylinder 1 63, which drives the linkage rod 1 67 and the limiting connecting rod 6561 to move at the same time, so that the movable rod 6564 is separated from the transmission gear 6563, and the limiting effect between the convex connecting frame 651 and the triangular extrusion body 6551 is released. At the same time, by controlling the servo motor 5, the two sets of clamping mechanisms 6 are moved away from each other. At this time, the metal plate will fall on the support plate 64, completing the entire processing work.

[0045] Example 2: Figure 7 As shown, on the basis of Example 1, the movable clamp 652 consists of a movable clamp 1 and a movable clamp 2, the movable clamp 1 is slidingly connected to the side wall of the convex-shaped connecting frame 651, and the movable clamp 2 is rotatably installed on the side wall of the movable clamp 1; the fixed clamp 653 consists of a fixed clamp 1 and a fixed clamp 2, the fixed clamp 1 is fixed on the side wall of the convex-shaped connecting frame 651, and the fixed clamp 2 is rotatably installed on the side wall of the fixed clamp 1 through an axis. At this time, the movable clamp 2 and the fixed clamp 2 are rotatably connected, so that the clamping angles between the multiple groups of support clamps 65 can be variable, thereby realizing the clamping and fixation of non-planar metal plates, and the adaptation effect is better.

[0046] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
