Description

Technical Field

[0001] This utility model relates to the field of sheet metal production technology, and in particular to a progressive local shaping press for sheet metal parts. Background Technology

[0002] In modern industrial production, the processing of thin sheet metal parts is an indispensable part of the manufacturing process. With the increasing demands for product quality and production efficiency, progressive local shaping presses, as an advanced processing equipment, are widely used in the forming process of thin sheet metal parts. This equipment, through a progressive local shaping method, can precisely process thin sheet metal parts, meeting the production needs of complex shapes and high precision requirements.

[0003] However, clamping and fixing thin sheet metal parts is a crucial step in actual operation. To ensure the stability of the processing and the quality of the forming, progressive local shaping presses typically clamp and fix the four corners of the thin sheet metal parts. This fixing method can, to a certain extent, ensure the stability of the thin sheet metal parts during processing and prevent displacement under stress. Traditional clamping and fixing methods mainly achieve this through the cooperation of bolts, a lower pressure plate, and an upper pressure plate. The specific operating steps are as follows: First, the position of the lower pressure plate needs to be adjusted according to the initial position of the thin sheet metal parts so that it can accurately fit the four corners of the thin sheet metal parts. Then, the lower pressure plate is fixed to the worktable of the progressive local shaping press with bolts to ensure that the lower pressure plate will not move during processing. Next, the thin sheet metal parts are placed on the lower pressure plate, and the upper pressure plate is used with bolts to further fix the thin sheet metal parts. The function of the upper pressure plate is to firmly press the thin sheet metal parts onto the lower pressure plate through the tightening force of the bolts, thereby achieving a stable clamping of the four corners of the thin sheet metal parts.

[0004] Because the lower pressure plate is fixed by bolts, when its position needs to be adjusted to accommodate thin sheet metal parts of different sizes, the operator must first remove each bolt from the lower pressure plate before adjusting its position. This operation is not only time-consuming and labor-intensive, but also prone to loosening or damage of the bolts during frequent adjustments, thus affecting the reliability of the clamping and fixing. After adjustment, the lower pressure plate must be re-fixed to the worktable with bolts, and the bolts must be tightened again. This process not only increases the operator's workload but also significantly reduces production efficiency, hindering the efficient and progressive local shaping of thin sheet metal parts.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-4A progressive local shaping press for sheet metal parts includes a machine body 1. An adjustment assembly is installed inside the machine body 1, and a movable plate 4 is installed inside the machine body 1 via the adjustment assembly. The adjustment assembly includes a first drive motor 2 located on the right side of the machine body 1. A first screw 3 is fixedly installed at the output end of the first drive motor 2, rotatably connected to the machine body 1, and threadedly connected to the movable plate 4. The adjustment assembly facilitates adjustment of the distance between the movable plates 4, thereby facilitating adjustment of the left-right distance of the movable frame 11. A guide rod 5 is fixedly installed inside the machine body 1, and the movable plate 4 is slidably connected to the guide rod 5. The guide rod 5 facilitates... The moving plate 4 is guided to move more stably. A mounting plate 6 is fixedly installed on the rear side of the moving plate 4. A rotating rod 7 is rotatably connected inside the mounting plate 6. A transmission assembly is provided on the surface of the rotating rod 7. A moving frame 11 is provided on the front side of the rotating rod 7 via the transmission assembly. The moving frame 11 is slidably connected to the moving plate 4. The transmission assembly includes a first bevel gear 8 disposed on the surface of the rotating rod 7, a second bevel gear 9 meshing on the surface of the first bevel gear 8, a second screw 10 fixedly installed inside the second bevel gear 9, the second screw 10 being rotatably connected to the moving plate 4, and the second screw 10 being threadedly connected to the moving frame 11. The transmission assembly facilitates transmission when the rotating rod 7 rotates, thus allowing for easy adjustment of the front-to-back distance of the movable frame 11. The movable frame 11 contains a clamping assembly, and a drive assembly is located on the top of the machine body 1. A rectangular rod 17 is mounted on the top of the machine body 1 via the drive assembly, and the rectangular rod 17 is slidably connected to the rotating rod 7. A moving assembly is also located on the top of the machine body 1, and a hydraulic push rod 23 is mounted on the top of the machine body 1 via the moving assembly. A pressure head 24 is fixedly installed at the output end of the hydraulic push rod 23. This sheet metal progressive local shaping press allows for adjustment of the distance between the movable plates 4 via the adjusting assembly, thereby facilitating the adjustment of the left-to-right distance between the movable frame 11. The rectangular rod 17 is rotated by the drive component, which in turn rotates the rotating rod 7, causing the transmission component to drive the transmission and the moving frame 11 to move relative to each other. The distance between the front and rear of the moving frame 11 is adjusted. Then, the four corners of the thin sheet metal part are placed in the moving frame 11, and the four corners of the thin sheet metal part are clamped and fixed by the clamping component. Then, the thin sheet metal part is extruded and shaped by the cooperation of the moving component, hydraulic push rod 23 and pressure head 24. This solution simplifies the adjustment process and significantly improves the adjustment efficiency, so as to adapt to the clamping requirements of thin sheet metal parts of different sizes more quickly, and thus complete the shaping process of thin sheet metal parts more quickly.

[0022] It is worth mentioning that the rotating rod 7 is rotatably connected to the mounting plate 6, while the mounting plate 6 is fixedly connected to the movable plate 4. The rectangular rod 17 is slidably connected to the rotating rod 7. The rectangular rod 17 will not move to the rotating rod 7 to move, and therefore will not move to the movable plate 4 to move. The rectangular rod 17 has a rectangular structure. When the rectangular rod 17 rotates, the rotating rod 7 can rotate at the same time, which makes it easier for the second screw 10 to rotate at the same time. This makes it easier for the two sets of movable frames 11 to move back and forth at the same time, which makes it easier to adjust the front and back distance between the movable frames 11 at the same time, so that the front and back distance between the two sets of movable frames 11 is the same. This makes it easier to clamp and fix the four corners of the thin sheet metal parts. The first screw 3 and the second screw 10 are both bidirectional threaded rods. When the first screw 3 rotates, the movable plates 4 will move closer or further away from each other. When the second screw 10 rotates, the movable frames 11 will move closer or further away from each other.

[0023] Specifically, the clamping assembly includes an electric push rod 12 located on the top of the movable frame 11. A pressure plate 13 is fixedly installed at the output end of the electric push rod 12. The clamping assembly facilitates the clamping and fixing of the four corners of the thin sheet metal part, thereby making it easier to process the thin sheet metal part more stably in the future.

[0024] Specifically, the drive assembly includes a fixed plate 14 disposed on the top of the body 1. A second drive motor 15 is fixedly installed on the right side of the fixed plate 14. A rotating shaft 16 is fixedly installed at the output end of the second drive motor 15. The rotating shaft 16 is rotatably connected to the fixed plate 14 and is fixedly connected to the rectangular rod 17. By setting the drive assembly, it is convenient to provide driving force for the rotation of the rectangular rod 17, thereby facilitating the rotation of the rectangular rod 17 and the simultaneous rotation of the rotating rod 7.

[0025] Specifically, the moving component includes a support frame 18 set on the top of the machine body 1. A first linear motor 19 is fixedly installed inside the support frame 18. A first moving seat 20 is set on the first linear motor 19. A second linear motor 21 is fixedly installed at the bottom of the first moving seat 20. A second moving seat 22 is set on the second linear motor 21. The second moving seat 22 is fixedly connected to the hydraulic push rod 23. By setting the moving component, it is convenient to adjust the front-back and left-right positions of the hydraulic push rod 23 and the pressure head 24, so that the pressure head 24 can more comprehensively extrude and shape the thin sheet metal parts.

[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0027] In use: The first drive motor 2 rotates the first screw 3, causing the moving plate 4 to move left and right along the guide rod 5, thus moving the moving frame 11 to a suitable position. The distance between the left and right sides of the moving frame 11 is adjusted. The second drive motor 15 rotates the rotating shaft 16, causing the rectangular rod 17 to rotate, which in turn rotates the rotating rod 7, causing the first bevel gear 8 to rotate, the second bevel gear 9 to rotate, and the second screw 10 to rotate, moving the moving frame 11 back and forth along the moving plate 4 to a suitable position. The distance between the front and back sides of the moving frame 11 is adjusted. Then, the four corners of the thin sheet metal part are placed inside the moving frame 11, and the electric push rod 12 presses... Plate 13 moves downwards, pressing the four corners of the thin sheet metal part. The hydraulic push rod 23 causes the pressure head 24 to move downwards, performing localized plastic extrusion on the thin sheet metal part. Then, the first linear motor 19 causes the first moving seat 20 to move left and right, causing the second linear motor 21, the second moving seat 22, the hydraulic push rod 23, and the pressure head 24 to move left and right, thereby adjusting the left and right position of the pressure head 24. The second linear motor 21 causes the second moving seat 22 to move back and forth, causing the hydraulic push rod 23 and the pressure head 24 to move back and forth, thereby adjusting the front and back position of the pressure head 24. This gradually completes all localized plastic extrusion operations on the thin sheet metal part.
