Abstract
Description
Technical Field
[0001] This utility model relates to the field of forming and bending device technology, and in particular to a forming and bending device for metal sheet metal parts. Background Technology
[0002] In fields such as machinery manufacturing and equipment housing processing, bending and forming of sheet metal parts is a key process. The application of sheet metal bending and forming equipment can achieve precise bending of sheet metal parts, ensure consistent bending angles, improve product quality stability, reduce errors from manual operation, speed up production, meet the needs of mass production, reduce production costs, provide compliant sheet metal components for various industries, and promote the efficient development of related industries.
[0003] In the existing technology, bending of sheet metal parts is mostly completed by bending machines. The relative movement of the upper and lower dies applies pressure to the sheet metal parts placed on the worktable, causing the sheet metal parts to undergo plastic deformation, thereby forming the required bending angle. The whole process relies on manual placement and removal of sheet metal parts, combined with simple mechanical transmission to control the bending action.
[0004] However, in the existing technology, metal sheet parts are often difficult to remove after bending because they are tightly attached to the bending die, requiring manual peeling. This not only increases the labor intensity of operators but also prolongs the processing time of a single workpiece, which seriously restricts production efficiency in mass production. Furthermore, improper operation during manual removal can easily lead to workpiece deformation or scratches, affecting product quality. Therefore, a metal sheet part forming and bending device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a metal sheet metal forming and bending device, which aims to improve the problem in the prior art that metal sheet metal parts are often difficult to remove after bending because they are tightly attached to the bending mold, requiring manual peeling.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A metal sheet metal forming and bending device includes a bending table, a guide column fixedly connected to the top of the bending table, a fixed seat fixedly connected to the top of the guide column, a cylinder fixedly connected to the top of the fixed seat, a slide plate fixedly connected to the output end of the cylinder, the slide plate slidably connected to the outer wall of the guide column, a limit rod fixedly connected to the bottom of the slide plate, a limit block slidably connected to the top of the bending table, an ejection component provided on one side of the limit block, and a bending component provided at the bottom of the slide plate.
[0008] The ejection assembly includes an ejection block, one side of which is fixedly connected to one side of a limiting block.

A sliding rod is fixedly connected to one side of the slider and is slidably connected inside the bending table. A spring is sleeved on the outer wall of the sliding rod, and both ends of the spring are fixedly connected to the bending table and the inside of the slider, respectively.
[0009] As a further description of the above technical solution:
[0010] The bending assembly includes a bending block and a mounting plate. The bending block is disposed at the bottom of the slide plate. The bottom of the mounting plate is fixedly connected to the top of the bending block. A support plate is disposed at the top of the mounting plate. A support column is fixedly connected to the top of the support plate. The support column is slidably connected inside the slide plate.
[0011] As a further description of the above technical solution:
[0012] The outer wall of the support column is fitted with a second spring, and the two ends of the second spring are respectively fixedly connected to the inside of the support plate and the slide plate. A stop block is fixedly connected to the top of the bending table, and a groove is opened inside the bending table.
[0013] As a further description of the above technical solution:
[0014] The bottom of the mounting plate is provided with a hollow column, and the top of the hollow column is fixedly connected with a positioning pin. The positioning pin is slidably connected inside the mounting plate and the support plate.
[0015] As a further description of the above technical solution:

[0017] As a further description of the above technical solution:

[0019] As a further description of the above technical solution:
[0020] A connecting ring is fixedly connected to the outer wall of the sliding column, and a button is fixedly connected to the bottom end of the sliding column.
[0021] As a further description of the above technical solution:
[0022] The outer wall of the sliding column is fitted with a spring three, and the two ends of the spring three are respectively fixedly connected to the connecting ring and the inside of the hollow column.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the slide plate is pushed down along the guide column by the cylinder, which drives the bending block to bend the sheet metal part. At the same time, the limiting rod triggers the limiting block, so that the ejector block ejects the sheet metal part under the cooperation of the slider and the spring. This achieves the effect of rapid bending and blanking of sheet metal parts, and solves the problem that sheet metal parts are often difficult to remove after bending because they are tightly attached to the bending mold, and need to be manually peeled off, thereby improving bending efficiency.
[0025] 2. In this utility model, pressing the button drives the sliding column to move upward, causing the conical block to release the locking ball and release the positioning pin lock. After replacing the bending block, the spring pushes the sliding column to reset and lock it, achieving the effect of convenient disassembly and assembly of the bending block. This solves the problem that the replacement of the traditional bending block requires the removal of multiple fasteners, which is cumbersome and has poor adaptability, thereby improving the flexibility of the bending device.

After the ejection action is completed, it can quickly drive the ejector block 10 to reset, preparing for the next bending. The bending assembly includes a bending block 17 and a mounting plate 16. The bending block 17 is located at the bottom of the slide plate 5. The bottom of the mounting plate 16 is fixedly connected to the top of the bending block 17. A support plate 15 is provided on the top of the mounting plate 16. A support column 14 is fixedly connected to the top of the support plate 15. The support column 14 is slidably connected inside the slide plate 5. A second spring 18 is sleeved on the outer wall of the support column 14. The two ends of the second spring 18 are fixedly connected to the support plate 15 and the slide plate 5, respectively. A stop block 7 is fixedly connected to the top of the bending table 1, which can laterally position the sheet metal part and prevent the workpiece from shifting during bending. A groove 6 is provided inside the bending table 1.
[0036] Reference Figure 1 , Figure 4 and Figure 5A hollow column 19 is provided at the bottom of the mounting plate 16. A positioning pin 21 is fixedly connected to the top of the hollow column 19. The positioning pin 21 is slidably connected inside the mounting plate 16 and the support plate 15. A sliding column 20 is slidably connected inside the hollow column 19.

[0037] Working principle: When using this forming and bending device to bend metal sheet parts, the metal sheet part to be bent is first placed on the top of the bending table 1. The sheet part is initially positioned using the stop block 7 and groove 6 on the top of the bending table 1. Then, the cylinder 4 is started. The output end of the cylinder 4 pushes the slide plate 5 to slide down along the outer wall of the guide column 2. The bending block 17 at the bottom of the slide plate 5, with the cooperation of the mounting plate 16, support plate 15, support column 14 and spring 18, moves closer to the sheet part for bending. During this process, the limiting rod 8 at the bottom of the slide plate 5 will contact the limiting block 9. The limiting block 9 is forced to move the ejector block 10. At the same time, the ejector block 10 drives the bottom slider 11 to slide inside the bending table 1. The slider 11 squeezes the spring 13 on one side. The ejector block 10 will contact the sheet part during the movement. The ejector block 10 applies pressure to the sheet part, thereby pushing it out of the groove 6, thus achieving the effect of quickly bending and cutting sheet parts.
[0038] When the bending block 17 needs to be replaced to adapt to different bending requirements, press the button 26 at the bottom of the hollow column 19 at the bottom of the mounting plate 16. The button 26 moves the sliding column 20 upward inside the hollow column 19, and the conical block 24 on the outer wall of the sliding column 20 moves accordingly, releasing the retaining ball 25 inside the positioning pin 21, so that the positioning pin 21 is disengaged from the mounting plate 16 and the support plate 15, and the old bending block 17 can be quickly removed. After replacing the new bending block 17, release the button 26, the spring 3 23 pushes the sliding column 20 to reset, the conical block 24 falls back, and the retaining ball 25 re-engages with the positioning pin 21 and the mounting plate 16, completing the locking of the bending block 17 and realizing convenient disassembly and assembly.
