Description

Technical Field

[0001] The utility model relates to the technical field of bending dies, in particular to a sheet metal stamping and bending die. Background Art

[0002] Sheet metal refers to metal components or parts of various shapes and sizes made by stamping, bending, folding, welding and other processing technologies on metal sheets. Sheet metal parts usually have complex shapes, such as curved surfaces, bumps, etc. During processing and production, bending molds are required to ensure the dimensional accuracy and shape accuracy of sheet metal parts. Bending molds have good repeatability and can maintain the consistency of sheet metal parts of the same shape and size, ensuring stable product quality. It is one of the important processes commonly used in sheet metal processing.

[0003] Traditional stamping and bending dies are usually composed of a die base, a die column, an upper die, a lower die and other structures. The die base is the basis for supporting and fixing the die, and the die column connects the die base with the upper and lower dies to play a supporting and guiding role. The upper and lower dies are the components that actually perform stamping and bending processing. Their shapes correspond to the shape of the final product. These components cooperate with each other to form a complete stamping and bending die system.

[0004] However, the traditional stamping and bending mold has a relatively simple structure. During processing, it can usually only bend the surface of the sheet metal part, but cannot process the side of the sheet metal part. As a result, the bending position of the workpiece cannot be selected according to demand during processing, which limits the flexibility and diversity of the mold. Therefore, a sheet metal stamping and bending mold is proposed to solve the above problems. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 3 The utility model provides an embodiment: a sheet metal stamping and bending mold, including a lower mold body 1 and an upper mold body 2, a support column 3 is slidably connected inside the upper mold body 2, a pressing plate 5 is fixedly connected to the bottom end of the support column 3, a first spring 4 is sleeved on the outer wall of the support column 3, the top of the first spring 4 is fixedly connected to the inside of the upper mold body 2, the bottom of the first spring 4 is fixedly connected to the inside of the pressing plate 5, a pressing block 6 is arranged at the bottom of the pressing plate 5, a limiting block 7 is fixedly connected to the bottom of the upper mold body 2, a slide rail 8 is fixedly connected to the top of the lower mold body 1, an inclined slider 12 is slidably connected to the inside of the slide rail 8, and the inclined slider 12 is The side bottom is slidably connected to the inside of the lower mold body 1, a bending block 9 is fixedly connected to one side of the inclined sliding block 12, a bending groove 11 is opened inside the lower mold body 1, a positioning frame 10 is fixedly connected to the top of the lower mold body 1, and a connecting component is arranged inside the lower mold body 1, and the connecting component includes a sliding column 13, the outer wall of the sliding column 13 is slidably connected to the inside of the lower mold body 1, one end of the sliding column 13 is fixedly connected to the bottom of one side of the inclined sliding block 12, the outer wall of the sliding column 13 is sleeved with a second spring 14, one end of the second spring 14 is fixedly connected to the inside of the lower mold body 1, and the other end of the second spring 14 is fixedly connected to the bottom of one side of the inclined sliding block 12.

[0034] Specifically, when the mold is used to process a workpiece, when it is necessary to bend the middle of the workpiece, the upper mold body 2 is driven to drive the support column 3 to move, and then the pressure plate 5 is driven to move. Under the action of force, the pressure plate 5 moves the pressure block 6 at the bottom, and presses the workpiece into the bending groove 11 to complete the bending. If it is necessary to bend the side of the workpiece, the movement of the upper mold body 2 will simultaneously drive the limit block 7 to move during processing. At this time, it is necessary to remove the pressure block 6 from the bottom of the pressure plate 5 by bolts, and then use the pressure plate 5 to fix the workpiece. At the same time, the limit block 7 will contact the inclined slide block 12 during the movement, causing the inclined slide block 12 to slide inside the slide rail 8, thereby driving the bending block 9 on one side to move and bend the side of the workpiece. In addition, the inclined slide block 12 will also drive the sliding column 13 connected to the bottom to slide inside the lower mold body 1, squeeze the second spring 14 to make it shrink. After the processing is completed, the rebound of the second spring 14 will drive the inclined slide block 12 to reset, so that the entire mold system can flexibly select the bending position, thereby meeting the processing requirements of different workpieces.

[0035] Reference Figure 4 and Figure 5 A connecting platform 15 is fixedly connected to one side of the lower mold body 1, a supporting plate 16 is fixedly connected to the top of the connecting platform 15, a cylinder 17 is fixedly connected to the top of the supporting plate 16, a connecting pipe 18 is fixedly connected to the output end of the cylinder 17, a connecting plate 21 is fixedly connected to the outer wall of the top column 20, a limiting groove 22 is provided inside the connecting plate 21, the outer wall of the connecting pipe 18 is slidably connected to the inside of the limiting groove 22, and a connecting rod 23 is rotatably connected to one side of the connecting plate 21.

[0036] Specifically, after the processing is completed, the cylinder 17 drives the connecting pipe 18 to move through the output end, and the connecting pipe 18 slides inside the limiting groove 22 under the action of force. In this process, the limiting groove 22 is used to limit the connecting plate 21, thereby achieving the driving effect.

[0037] Reference Figure 4 and Figure 5 A sleeve 19 is fixedly connected to the top of the connecting platform 15, a top column 20 is slidably connected inside the sleeve 19, a fixed plate 25 is fixedly connected to the top of the connecting platform 15, one side of the connecting rod 23 is rotatably connected to a rotating rod 24, and one side of the rotating rod 24 is rotatably connected to one side of the fixed plate 25.

[0038] Specifically, the connecting plate 21 drives the top column 20 fixedly connected at the bottom to slide inside the sleeve 19 under the action of force, and at the same time, the connecting plate 21 also drives the connecting rod 23 connected on one side to rotate, and the movement of the connecting rod 23 further drives the rotating rod 24 connected on one side to rotate on the side of the fixed plate 25. Under the coordinated action of these movements, the movement of the top column 20 ejects the workpiece from the mold, achieving the effect of rapid material removal.

[0039] Working principle: when the mold is used to bend the middle of the workpiece, the upper mold body 2 drives the support column 3 to move the support column 3, and the support column 3 drives the pressure plate 5 to move. The pressure plate 5 is forced to drive the pressure block 6 at the bottom to move, and the pressure block 6 presses the workpiece into the bending groove 11 to bend it. When the side of the workpiece needs to be bent, the upper mold body 2 will also drive the limit block 7 to move during the movement. At this time, it is necessary to remove the pressure block 6 from the bottom of the pressure plate 5 through the action of bolts, and the workpiece is pressed and fixed by the pressure plate 5. At the same time, the limit block 7 contacts the inclined slide block 12 during the movement, so that the inclined slide block 12 is forced to slide inside the slide rail 8, and the inclined slide block 12 is forced to move the bending block 9 on one side, and the bending block 9 is forced to move toward the side of the workpiece, thereby bending it. At the same time, the inclined slide block 12 will also drive the sliding column connected to the bottom of one side. 13 slides inside the lower mold body 1, thereby squeezing the second spring 14 to make it shrink. After the processing is completed, the rebound of the second spring 14 drives the inclined slide block 12 to reset, thereby achieving the effect of being able to select the bending position. After the processing is completed, the connecting pipe 18 is driven to move by the output end of the cylinder 17, and the connecting pipe 18 is forced to slide inside the limiting groove 22. The limiting groove 22 allows the connecting plate 21 to move. The connecting plate 21 is forced to drive the top column 20 fixed at the bottom to slide inside the sleeve 19. At the same time, the connecting plate 21 also drives the connecting rod 23 connected on one side to rotate. The connecting rod 23 is forced to drive the rotating rod 24 connected on one side to rotate on the side of the fixed plate 25. Through the movement of the top column 20, the workpiece is ejected from the mold, achieving the effect of rapid material removal.
