[0001] This invention relates to the field of sheet metal mold design technology, specifically to a sheet metal mold with continuous processing capability. Background Technology

[0002] Sheet metal molds achieve the function of punching materials through the cooperation of upper and lower molds. The upper mold is installed on the slide of the stamping machine to apply downward pressure, while the lower mold is fixed on the worktable, together forming the main frame of the mold.

[0003] Continuous processing sheet metal molds enable continuous material feeding and continuous material processing by using the continuous operation of the upper and lower molds, allowing the material to move continuously between different workstations and complete the processing.

[0004] In existing technologies, different processing molds and different processing stations are usually used to achieve continuous forming of materials. Punching is performed at the blanking station, and bending or stretching is performed at the forming station. Therefore, several stations are required to achieve the function of continuous processing. This method increases the size of the sheet metal mold, which affects the accuracy of the sheet metal mold and affects the quality of the finished product when working together. Summary of the Invention

[0005] The purpose of this invention is to provide a sheet metal mold with continuous processing capability.

[0006] The technical problem solved by this invention is to address the issue of large sheet metal dimensions caused by the use of multiple different workstations in existing molds to perform sheet metal functions.

[0007] The present invention can be achieved by the following technical solution: a sheet metal mold with continuous processing capability, including an upper mold and a lower mold, wherein a stamping assembly is provided between the upper mold and the lower mold, the stamping assembly includes a stamping shell, a thin-walled cutting blade is provided on the bottom inner wall of the stamping shell, a forming mold that can move longitudinally is provided inside the thin-walled cutting blade, and a separable forming cavity is provided inside the lower mold.

[0008] A further technical improvement of the present invention is that a longitudinal hydraulic cylinder is fixed inside the stamping shell, and a bottom pressure plate is provided at the output end of the longitudinal hydraulic cylinder, and the forming mold is fixed on the bottom pressure plate.

[0009] A further technical improvement of the present invention is that the molding cavity is composed of a first molding plate and a second molding plate, the first molding plate being installed at the output end of the first moving component and the second molding plate being installed at the output end of the second moving component.

[0010] A further technical improvement of the present invention is that: the molding die is provided with a molding area and a guiding area, and the molding cavity includes a mating molding arc plate for mating with the molding area and a mating guiding arc plate for mating with the guiding area.

[0011] A further technical improvement of the present invention is that: the first moving component includes a cooperating cylinder, the cooperating cylinder is fixed on the lower mold, the output end of the cooperating cylinder is fixed with a clamping support plate, the output end of the clamping support plate is provided with a clamping arc plate, and the clamping arc plate is longitudinally slidably connected to the first forming plate and the second forming plate respectively through a support spring.

[0012] A further technical improvement of the present invention is that: a clamping groove is provided on the clamping support plate, a clamping slide plate is slidably arranged inside the clamping groove, a clamping spring is fixed between the clamping slide plate and the clamping groove, and the clamping slide plate is fixedly connected to the clamping arc plate through a clamping slide rod.

[0013] A further technical improvement of the present invention is that: a hinged base is fixed on the clamping support plate, and a mating arc plate is rotatably arranged on the hinged base by a torsion spring, and the mating arc plate respectively mates with the first forming plate and the second forming plate.

[0014] A further technical improvement of the present invention is that a limiting post is fixed on the clamping support plate, and the limiting post cooperates with the matching arc plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This application solves the problem of excessive overall mold size caused by setting up multiple independent workstations in the prior art by integrating the punching function (thin-wall cutting blade) and the forming function (forming mold) into the same stamping component, and integrating a separable forming cavity in the lower mold, thereby achieving efficient use of space.

[0016] 2. This application avoids the cumulative errors caused by multiple positioning of the strip at different stations in multi-station dies because the punching and forming processes are completed continuously in the same station. This integrated forming method can ensure the processing accuracy of sheet metal parts and improve product consistency.

[0017] 3. This solution can complete the continuous processing of "punching-forming" in one workstation, reducing the reliance on multiple molds or multi-process stamping equipment, simplifying the production process, and helping to improve the output efficiency per unit time.

[0018] 4. The molding die of this application is provided with a guide area, which interacts with the matching guide arc plate in the molding cavity, effectively preventing the processed material from slipping out or shifting during the molding process. At the same time, the separable molding cavity structure (first and second molding plates) and the moving components can form a complete and stable molding space.

[0019] 5. The molding cavity of this application adopts a separable first molding plate and second molding plate structure. After molding is completed, the two can move in opposite directions, which facilitates the smooth unloading of the molded parts and is conducive to realizing the automation and continuous production of molds.

[0020] 6. The moving component of this application is equipped with clamping springs, support springs, and mating arc-shaped plates. During the molding process, these components can provide stable clamping force and adaptively adjust when the molding die is pressed down to ensure close contact between the first and second molding plates, thereby ensuring the sealing and rigidity of the molding cavity.

[0024] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0025] Please see Figure 1-7 As shown, a sheet metal mold with continuous processing capability includes an upper mold 1 and a lower mold 5. The lower mold 5 is fixed at a fixed position, while the upper mold 1 and the lower mold 5 are slidably connected. The distance between the upper mold 1 and the lower mold 5 is achieved by a hydraulic cylinder installed inside them to achieve longitudinal relative sliding, thereby realizing longitudinal stamping of the workpiece 4. Several stamping holes 3 are formed on the workpiece 4. Therefore, a stamping assembly 2 is provided on the upper mold 1. The upper mold 1 drives the stamping assembly 2 to move longitudinally, so that the stamping assembly 2 acts on the workpiece 4, thereby feeding the material out from the blanking hole 6 on the lower mold 5. At the same time, the workpiece 4 has stamping holes 3 formed on it.

[0026] Furthermore, the stamping assembly 2 includes a stamping housing 7, and a thin-walled cutting blade 8 is provided at the bottom of the stamping housing 7. In use, the stamping housing 7 is fixed on the upper die 1. In use, the longitudinal movement of the upper die 1 drives the stamping housing 7 to move longitudinally, so that the thin-walled cutting blade 8 acts on the workpiece 4 to punch the workpiece 4, thereby realizing the punching of the workpiece.

[0027] Furthermore, a forming mold 9 is provided inside the stamping shell 7, wherein the forming mold 9 moves longitudinally inside the stamping shell 7, and a forming cavity 12 is provided inside the lower mold 5. In use, after the thin-walled cutting blade 8 finishes cutting, the forming mold 9 slides longitudinally inside the stamping shell 7, so that the forming mold 9 can extend out of the stamping shell 7 and act inside the forming cavity 12. At this time, the cut material 4 is transferred into the forming cavity 12, and the material 4 is formed by applying external pressure.

[0028] Furthermore, in order to achieve the longitudinal movement of the forming mold 9, a longitudinal hydraulic cylinder is fixed inside the stamping shell 7, and a bottom pressure plate 10 is provided at the output end of the longitudinal hydraulic cylinder. The forming mold 9 is provided at the output end of the bottom pressure plate 10. The forming mold 9 includes a forming area 14 and a guiding area 15. In use, the pressure of the forming area 14 is used to stamp and form the workpiece 4, and the guiding area 15 is used to prevent the workpiece 4 from slipping out.

[0029] Furthermore, the forming cavity 12 is formed by a separable first forming plate 11 and a second forming plate 13, wherein the first forming plate 11 and the second forming plate 13 can move towards or away from each other, and a connecting groove 20 is provided between the first forming plate 11 and the second forming plate 13. When the forming mold 9 moves longitudinally, the first forming plate 11 and the second forming plate 13 are connected to form the forming cavity 12, which facilitates the material 4 to fall into the forming cavity 12 for pressure forming. The separation of the first forming plate 11 and the second forming plate 13 enables the material 4 to be unloaded after forming. The material 4 is unloaded from the unloading hole 6. Therefore, in this application, by integrating punching and forming equipment inside the unloading hole 6, the material 4 can be integrally formed, thereby reducing the overall volume of the mold and ensuring the efficiency of mold use. Moreover, the integrated mold can ensure the precision of sheet metal.

[0030] Furthermore, taking the first forming plate 11 as an example, the first forming plate 11 is provided with a mating forming arc plate 17 for mating with the forming area 14. A mating guiding arc plate 16 is provided on the mating forming arc plate 17. The mating guiding arc plate 16 and the guiding area 15 are mated, thereby enabling the mating of the forming mold 9 and the forming cavity 12 structure.

[0031] In order to achieve relative separation of the first molding plate 11 and the second molding plate 13, the first molding plate 11 is fixed at the output end of the first moving component 18 and the second molding plate 13 is fixed at the output end of the second moving component 19. Therefore, in use, the relative separation or contact of the first molding plate 11 and the second molding plate 13 is achieved by the cooperation of the first moving component 18 and the second moving component 19.

[0032] Specifically, taking the first moving component 18 as an example, the first moving component 18 includes a cooperating cylinder 28, which is fixedly installed inside the lower mold 5. The output end of the cooperating cylinder 28 is provided with a clamping arc plate 26. The bottom of the first forming plate 11 and the second forming plate 13 are symmetrically installed with a first support column 21 and a second support column 22. The clamping arc plate 26 acts on the first support column 21 and the second support column 22. External pressure is applied to the clamping arc plate 26. The clamping arc plate 26 is longitudinally slidably connected to the first support column 21 and the second support column 22 through support springs, thereby controlling the distance between the first forming plate 11 and the second forming plate 13, so that the distance between the first forming plate 11 and the second forming plate 13 is closer, thereby realizing the contact between the first forming plate 11 and the second forming plate 13 and realizing the formation of the forming cavity 12. The first forming plate 11 and the second forming plate 13 are slidably connected to the lower mold 5.

[0033] Specifically, a clamping support plate 27 is provided at the output end of the hydraulic cylinder 28. The clamping support plate 27 has a clamping groove 30, and a clamping spring 31 is fixed inside the clamping groove 30. The other end of the clamping spring 31 is fixed to the clamping slide plate 32. A clamping slide rod 33 is fixed to the side of the clamping slide plate 32. The clamping slide plate 32 and the clamping groove 30 are slidably connected. At the same time, the clamping arc plate 26 is fixed to the output end of the clamping slide rod 33. In this application, the clamping spring 31 is used to pull the clamping slide plate 32. When in use, the clamping arc plate 26 can squeeze the clamping spring 31 until it is squeezed to the deepest point, which facilitates the clamping function of the first forming plate 11 and the second forming plate 13. When releasing, the clamping spring 31 is used to maintain the gradual separation of the first forming plate 11 and the second forming plate 13, thereby maintaining the separation stability of the first forming plate 11 and the second forming plate 13.

[0034] As a further embodiment of this application, a hinge base 24 is fixed on the top of the clamping support plate 27. A mating arc plate 23 is rotatably mounted on the hinge base 24 via a torsion spring. The mating arc plate 23 is used to mate with the first molding plate 11. When the molding mold 9 is pressed down into the molding cavity 12, it overcomes the elastic force of the support spring. At this time, the first molding plate 11 and the second molding plate 13 move downward and contact the mating arc plate 23. Utilizing the arc shape on the mating arc plate 23, the mating arc plate 23 rotates against the torsion spring until the mating arc plate 23 contacts and connects with the first molding plate 11 and the second molding plate 13, thereby enabling the first molding plate 11 and the second molding plate 13 to be in close contact.

[0035] As a further embodiment of this application, a limiting post 29 for limiting the mating arc plate 23 is fixed on the clamping support plate 27 to prevent the mating arc plate 23 from rotating excessively and to maintain the stability of the first forming plate 11 and the second forming plate 13.

[0036] In use, the upper mold 1 moves longitudinally, which drives the stamping shell 7 to move longitudinally, so that the thin-walled cutting blade 8 acts on the workpiece 4 to punch the workpiece 4, thereby realizing the punching of the workpiece. Then, the longitudinal hydraulic cylinder drives the forming mold 9 to move longitudinally, and the forming area 14 pressurizes the workpiece 4 to form it. The guide area 15 prevents the workpiece 4 from slipping out. Therefore, in this application, in order to achieve the molding of the molding material, the clamping arc plate 26 is pressed by the cooperating oil cylinder 28, and the clamping arc plate 26 is longitudinally slidably connected to the first support column 21 and the second support column 22 through the support spring, thereby controlling the distance between the first molding plate 11 and the second molding plate 13, so that the distance between the first molding plate 11 and the second molding plate 13 is close, thereby achieving the contact between the first molding plate 11 and the second molding plate 13, and realizing the formation of the molding cavity 12, wherein the first molding plate 11 and the second molding plate 13 are slidably connected to the lower mold 5; During this process, when the molding die 9 is pressed down inside the molding cavity 12, it overcomes the elastic force of the support spring. At this time, the first molding plate 11 and the second molding plate 13 move downward and contact the mating arc plate 23. Utilizing the arc shape on the mating arc plate 23, the mating arc plate 23 rotates against the torsion spring until the mating arc plate 23 contacts and connects with the first molding plate 11 and the second molding plate 13, thereby enabling the first molding plate 11 and the second molding plate 13 to be in close contact. In order to realize the unloading of the molding material, the hydraulic cylinder 28 is activated to control the clamping support plate 27 to move backward, thereby increasing the distance between the first molding plate 11 and the second molding plate 13, which facilitates the unloading.
