[0010] Further, a groove is formed in the middle of the top of the material guide table, and the width of the groove is greater than the width of the push plate.

[0011] By adopting the technical scheme, the push plate is prevented from colliding with the material guide table during lifting and rotation by the groove.

[0012] Further, the push plate is rotationally connected to the upper die through a second torsion spring shaft.

[0013] By adopting the technical scheme, the upper die pulls the push plate through the pull rope, the push plate is pulled and rotated to push up the plate, at this time, the push plate and the plate are both in a slope shape.

[0014] Further, top frames and placement tables are arranged on both sides of the top of the base, a hydraulic cylinder is installed on the top of each top frame, the upper die is connected to the output end of the hydraulic cylinder, and the lower die is connected to the middle of the top of the base.

As the upper mold moves down, the straight sheet material is stamped into an n-shape by the cooperation of the upper and lower molds; then the upper mold continues to move down and presses against the lower mold through the sheet material, thereby causing the lower mold to move down and compress the second spring. At the same time as the lower mold moves down, it drives the pressure plate to move down.

The pressure plate moves down and abuts against the top of the base, causing the pressure plate to rotate under force. After the pressure plate rotates under force, it also applies pressure to the sheet material, thereby stamping the n-shaped sheet material into a Z-shaped material.

[0025] This invention utilizes a guide platform, a push plate, a second torsion spring shaft, and a pull rope. When the upper mold rises to the upper section, the lower mold cannot continue to move upwards. The upper mold then pulls the push plate via the pull rope. Once pulled, the push plate rotates and pushes the sheet material up. At this point, both the push plate and the sheet material are inclined. Gravity causes the sheet material to slide down the inclined push plate and the slope at the top of the guide platform. Workers can place a container near the lower part of the outer surface of the guide platform to collect the sheet material. This facilitates automatic unloading, and the concentrated unloading location makes collection convenient. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] Example 1:

[0034] A precision metal stamping die capable of multi-angle stamping, such as... Figures 1-4 As shown, the system includes a base 1, an upper mold 4, and a lower mold 5. A push plate 8 is connected inside the lower mold 5 via a second torsion spring shaft 9. The push plate 8 is rotatably connected to the upper mold 4 via the second torsion spring shaft 9. A pull rope 10 is connected between the push plate 8 and the upper mold 4. A guide platform 7 is connected to the top of the base 1. The top of the guide platform 7 is sloping, and a groove is opened in the middle of the top of the guide platform 7. The width of the groove is greater than the width of the push plate 8. The upper mold 4 pulls the push plate 8 via the pull rope 10. After being pulled, the push plate 8 rotates and pushes the sheet material up. At this time, both the push plate 8 and the sheet material are sloping. Thus, the sheet material slides down the inclined push plate 8 and the sloping surface of the top of the guide platform 7 by gravity. Workers can place a container at the lower position of the outer surface of the guide platform 7 to collect the sheet material.

[0035] See Figures 1-4 In the above embodiment, a top frame 2 and a placement platform 6 are provided on both sides of the top of the base 1. A hydraulic cylinder 3 is installed on the top of the top frame 2. The upper mold 4 is connected to the output end of the hydraulic cylinder 3, and the lower mold 5 is connected to the middle of the top of the base 1. When the operator starts the hydraulic cylinder 3, the output end of the hydraulic cylinder 3 drives the upper mold 4 to move down to start the stamping work.

[0036] Example 2:

[0037] Based on the above embodiment one, in order to facilitate multi-angle stamping to achieve the effect of one-time stamping, the following settings are now adopted.

[0038] See Figures 1-4 In the above embodiment, a pressure frame 401 is connected inside the upper mold 4. The pressure frame 401 has an "I" shaped cross section and is slidably connected to the upper mold 4. An upper spring 402 is connected to the top of the pressure frame 401. A lower spring 501 is connected to the bottom of the lower mold 5. The lower mold 5 is slidably connected to the base 1. A pressure plate 502 is connected inside the lower mold 5 through a first torsion spring shaft 503. The pressure plate 502 is rotatably connected to the lower mold 5 through the first torsion spring shaft 503. The bottom of the pressure plate 502 is arc-shaped and abuts against the base 1. The upper mold 4 continues to move down and abuts against the lower mold 5 through the sheet metal, thereby causing the lower mold 5 to move down and compress the second spring. At the same time as the lower mold 5 moves down, it drives the pressure plate 502 to move down. The pressure plate 502 moves down and abuts against the top of the base 1, thereby causing the pressure plate 502 to rotate under force. After the pressure plate 502 rotates under force, it also applies pressure to the sheet metal, thereby stamping the n-shaped sheet metal into a Z-shaped shape.

[0039] The implementation principle of this utility model is as follows: First, the stroke of the upper mold 4 is divided into three sections, namely the upper section, the middle section and the lower section. The upper section is for unloading, the middle section is for loading, and the lower section is for stamping. The upper mold 4, the lower mold 5 and the pressure plate 502 are all provided with springback allowance, so that the sheet metal can reach the predetermined shape when it springs back after stamping. At the same time, the springback of the sheet metal prevents the sheet metal from getting stuck on the lower mold 5 and the push plate 8. This technical solution operates based on the above two background support.

[0040] The worker places the sheet metal on two placement platforms 6, then activates the hydraulic cylinder 3. Upon activation, the output of the hydraulic cylinder 3 drives the upper die 4 downwards, moving it from the middle section to the lower section to begin the stamping process. At this time, the pressure frame 401 first contacts the sheet metal and applies pressure through the upper spring 402, thus preventing the sheet metal from shifting. As the upper die 4 moves downwards, the straight sheet metal is stamped into an "n" shape by the cooperation of the upper die 4 and the lower die 5. Then, the upper die 4 continues to move downwards, pressing against the lower die 5 through the sheet metal, causing the lower die 5 to move downwards and compress the second spring. Simultaneously, the downward movement of the lower die 5 drives... The pressure plate 502 moves downward and abuts against the top of the base 1, causing the pressure plate 502 to rotate under force. After rotating under force, the pressure plate 502 also applies pressure to the sheet metal, thereby stamping the n-shaped sheet metal into a Z-shaped sheet metal. Afterward, the operator moves the upper mold 4 to the middle position through the hydraulic cylinder 3 to end the stamping. After the upper mold 4 moves upward, it separates from the sheet metal. The upper spring 402 drives the pressure frame 401 to move downward to prepare for the next clamping of the sheet metal, the lower spring 501 drives the lower mold 5 to move upward to prepare for the next stamping, and the first torsion spring shaft 503 drives the pressure plate 502 to reset to prepare for the next stamping.

[0041] The worker moves the upper die 4 to the upper segment position through the hydraulic cylinder 3, when the upper die 4 is lifted to the upper segment, the upper die 4 pulls the push plate 8 through the pull rope 10 because the lower die 5 cannot continue to move upwards, the push plate 8 is pulled and rotated to push the plate material, at this time, the push plate 8 and the plate material are both in the shape of an inclined plane, so that the plate material slides along the inclined push plate 8 and the inclined surface on the top of the material guide table 7 through gravity, the worker can place a container at the lower position on the outer surface of the material guide table 7 to collect the plate material, after the discharging is completed, the worker moves the upper die 4 back to the middle segment through the hydraulic cylinder 3, prepares to feed and prepares the next stamping work, and drives the push plate 8 to reset through the second torsional spring shaft 9 to prepare the next discharging work.
