Technical Field

[0001] The utility model relates to the technical field of stamping equipment, in particular to an integrated die for punching and forming complex curved surfaces with hole drawing. Background Technique

[0002] In metal processing and manufacturing industries, the stamping forming and hole drawing operations of complex curved surfaces are common technological requirements. Especially in industries such as automobiles, aerospace, and household appliances, extremely high requirements are placed on the accuracy, strength, and aesthetics of components.

[0003] In the prior art, most stamping forming and hole drawing operations are often completed by two sets of independent dies and equipment. This not only increases production costs but also reduces production efficiency. At the same time, it is difficult to ensure the consistency of machining accuracy. For complex curved surface parts that require hole drawing operations directly after forming, additional hole drawing equipment often needs to be set up, and the parts are transferred from the stamping die to the hole drawing equipment manually or by a robotic arm, etc. There are problems of multiple clamping and positioning in this process, which not only increases the operation complexity but also easily introduces errors, affecting the final quality of the product. When replacing the upper and lower dies of traditional dies, a large amount of time and effort is usually required for disassembly, installation, and debugging, which not only reduces production flexibility but also increases maintenance costs. Content of the Utility Model

[0004] The purpose of the utility model is to provide an integrated die for punching and forming complex curved surfaces with hole drawing to solve the problems mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An integrated die for punching and forming complex curved surfaces with hole drawing includes a mounting base. A first fixing plate is arranged on the top of the mounting base, and a lower die is arranged on the first fixing plate. An installation plate is also arranged on the mounting base. A plurality of hydraulic rods are evenly arranged at the bottom of the installation plate. The end of the telescopic arm of the hydraulic rod at the bottom is provided with a second fixing plate, and an upper die is arranged on the second fixing plate. Through holes are arranged through the upper die and the lower die. A limiting block is also arranged on the installation plate.

[0009] As a further solution of the present utility model: a threaded hole is penetrated through the cross bar, and a third bolt used in cooperation with the limiting block is arranged in the threaded hole through threaded connection.

[0010] As a further solution of the present utility model: a threaded hole is also penetrated through the slider, and a fourth bolt used in cooperation with the cross bar is arranged in the threaded hole through threaded connection.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] Embodiment

[0020] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, an integrated die for punching and forming complex curved surfaces includes a mounting base 1. A first fixing plate 2 is provided on the top of the mounting base 1. A lower die 3 is provided on the first fixing plate 2 through a second bolt 8. An installation plate 4 is also provided on the mounting base 1. A plurality of hydraulic rods 5 are evenly provided at the bottom of the installation plate 4. The end of the telescopic arm of the hydraulic rod 5 at the bottom is provided with a second fixing plate 6. An upper die 9 is provided on the second fixing plate 6 through a first bolt 7. At this time, under the action of the hydraulic rod 5, the upper die 9 can be driven to move downward. When punching and forming is required, the staff places the forming material on the lower die 3, and then starts the hydraulic rod 5 to drive the upper die 9 to move downward. At this time, under the combined use of the upper die 9 and the lower die 3, the punching and forming work of the forming material is completed. When it is necessary to replace the upper die 9 and the lower die 3, the staff removes the first bolt 7 and the second bolt 8. At this time, the upper die 9 and the lower die 3 can be removed, thus facilitating the replacement of the upper die 9 and the lower die 3, and further enabling the device to better meet the actual use requirements, thereby improving the applicability of the device to a certain extent.

[0021] Through holes 10 are provided through the upper die 9 and the lower die 3. At this time, under the action of the through holes 10, it is convenient for subsequent hole punching of the formed object. To a certain extent, the device can not only complete the punching and forming work of the forming material, but also facilitate the hole punching work of the object, thereby improving the use efficiency of the device to a certain extent.

[0022] A limiting block 11 is also provided on the installation plate 4. A cross bar 12 is slidably provided on the limiting block 11. A slider 13 is slidably provided on the cross bar 12. An electric push rod 14 is provided at the bottom of the slider 13 through a fixing plate. The end of the telescopic arm of the electric push rod 14 at the bottom is provided with a hole punching device 15. Under the action of the cross bar 12 and the slider 13, the hole punching device 15 can be driven to move back and forth and left and right within a limited range, thereby meeting the requirements for hole punching at different positions, and further improving the use efficiency of the device to a certain extent.

[0023] The cross bar 12 is provided with threaded holes running through it. A third bolt 16 used in cooperation with the limit block 11 is connected by threading within the threaded holes. Under the action of the third bolt 16, the position of the cross bar 12 can be restricted, thus ensuring the usage efficiency of the hole punching device 15. The slider 13 is also provided with threaded holes running through it. A fourth bolt 17 used in cooperation with the cross bar 12 is connected by threading within the threaded holes. At this time, under the action of the fourth bolt 17, the position of the slider 13 can be restricted, thereby better restricting the hole punching device 15 and ensuring the usage efficiency of the hole punching device 15.

[0024] During actual use, the device is stably installed at the required position through the mounting base 1. The first fixing plate 2 is installed on the top of the mounting base 1, and a lower die 3 is fixed thereon by a second bolt 8, which is used to support and shape the molding material to be processed. At the same time, the mounting plate 4 is vertically arranged on the mounting base 1, and a plurality of hydraulic rods 5 are evenly installed below it. The ends of the telescopic arms of these hydraulic rods 5 are connected to the second fixing plate 6, and an upper die 9 is fixed on the second fixing plate 6 by a first bolt 7. When a stamping and forming operation is required, the staff first precisely places the molding material to be processed on the lower die 3. Subsequently, the hydraulic rods 5 are started, and their telescopic arms drive the upper die 9 to move downward until it is in close contact with the lower die 3 and applies sufficient pressure to complete the stamping and forming process of the material. By adjusting the telescopic amount of the hydraulic rods 5, the depth and strength of the stamping can be precisely controlled to ensure the forming accuracy and quality. After the stamping and forming is completed, if a hole punching operation needs to be performed on the formed object, the through hole 10 preset on the die can be used as a guide or reference. At this time, the limit block 11 on the mounting plate 4 provides a stable support platform, and the cross bar 12 can slide along the limit block 11 to adjust the lateral position of the hole punching device 15. At the same time, the slider 13 on the cross bar 12 can freely slide along the cross bar 12 to achieve fine adjustment of the hole punching device 15 in the longitudinal direction. By adjusting the tightening degree of the third bolt 16 and the fourth bolt 17, the positions of the cross bar 12 and the slider 13 can be locked respectively to ensure the stable operation of the hole punching device 15 at the specified position. The electric push rod 14 is started, and its telescopic arm pushes the hole punching device 15 to move downward to perform precise hole punching operations on the formed object. The stroke and speed of the electric push rod 14 can be adjusted according to needs to meet the requirements of different hole punching sizes and depths. After the hole punching is completed, the above steps can be reversed to retract the hole punching device 15 and prepare for the next stamping and forming or hole punching operation.
