Description

Technical Field

[0001] The present invention relates to the technical field of punching dies, and particularly relates to a punching die with a positioning structure. Background Art

[0002] In the manufacturing of aircraft and other spacecraft, the development of unmanned spacecraft is becoming more and more rapid, and the competition of unmanned spacecraft is also becoming increasingly fierce. Spacecraft are composed of components. In order to reduce the price of spacecraft components, a large number of components will be mass-produced using punching dies.

[0003] During the stamping production process of the punching press for spacecraft components, the stamped components still need to be manually taken out by personnel. Manual taking out by personnel has certain risks and increases the stamping interval time. When using compressed gas to eject the components, the stamping die is horizontal. For components with a certain weight, the compressed gas may not be able to blow them or has high requirements for wind speed, and it is also easy for the compressed gas to blow the components off track, resulting in the components still being on the die. If the die falls, it will cause the die to jam and the use is not stable enough. Summary of the Invention

The upper die member pulls one side of the lower die holder upward through the lower connecting frame and the outer connecting rod. The lower die holder, the lower die member, and the outer lifting platform tilt to one side synchronously. After the lower die member and the outer lifting platform tilt, the guiding member slides and exports to the lower side, eliminating the need for manual removal of the component by hand.

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0021] Embodiment 1: Please refer to Figures 1 to 8 : The present invention provides a punching die with a positioning structure, including: a lower die holder 1, a lower die fixing seat 2, an upper die holder 3, and a lower support rod 4. An outer connecting rod 101 is rotatably connected to the outer side of the middle part of the lower die holder 1 through a rotating shaft. On one side of the lower die holder 1, positioning slide rods 102 are symmetrically fixed. Outer lifting platforms 103 slide vertically in the slide tubes at the four corners of the top of the lower die holder 1. A lower die part 104 is fixed at the center of the top of the lower die holder 1. Lower support springs 105 are fixed between the four corners of the lower die holder 1 and the outer lifting platforms 103. The positioning slide rods 102 are slidably connected through the outer lifting platforms 103, and the positioning slide rods 102 are slidably connected through the upper die holder 3. The lower support springs 105 support the upward movement of the outer lifting platforms 103. The top surfaces of the outer lifting platforms 103 and the lower die part 104 are flush. The upward movement of the outer lifting platforms 103 ensures that the parts are at the top of the lower die part 104, avoiding the parts being stuck outside the lower die part 104. The upward movement of the outer lifting platforms 103 pushes the parts up to a reasonable position at the top, reducing the difficulty of moving and guiding the parts after stamping. The center of the lower die holder 1 is rotatably connected to the lower die fixing seat 2 through a rotating shaft. Intermediate gears 201 are rotatably connected to both sides of the lower die fixing seat 2. The top surface of the lower die fixing seat 2 is attached to the bottom surface of the horizontally placed lower die holder 1. The intermediate gears 201 are located outside the lower die holder 1. The tail synchronous rack 402 and the outer synchronous rack 306 move in opposite directions through the intermediate gears 201; An upper die holder 3 is arranged above the lower die holder 1. A side slide tube 301 is fixed on one side of the upper die holder 3. A lower connecting frame 302 is slidably connected to the side slide tube 301. During the upward movement of the upper die holder 3, the side slide tube 301 and the lower connecting frame 302 slide and extend. After the upper die holder 3 and the positioning slide rod 102 slide and separate, the side slide tube 301 and the lower connecting frame 302 reach the maximum length. The side slide tube 301 and the lower connecting frame 302 tilt the lower die holder 1 by pulling the outer connecting rod 101, avoiding the situation where the positioning slide rod 102 of the lower die holder 1 gets stuck. A lower positioning ring frame 303 slides vertically at the bottom of the upper die holder 3. The upper cross bar of the lower positioning ring frame 303 is fixedly connected to the middle ejecting column 304. An upper die part 305 is arranged at the bottom of the upper die holder 3. Outer synchronous racks 306 are fixed on both sides of the upper die holder 3. The outer synchronous racks 306 drive the tail synchronous rack 402 to move upward through the intermediate gears 201. A middle support spring 307 is fixed between the middle ejecting column 304 and the upper die holder 3. A lower support rod 4 slides vertically in the middle of the lower die fixing seat 2. Cylindrical side synchronous support rods 401 are fixed on both sides of the lower support rod 4. The side synchronous support rods 401 are slidably connected to the tail chute of the rectangular block-shaped side support rotating frame 403. The tail end of the side synchronous support rod 401 is fixed with a tail synchronous rack 402. The side synchronous support rods 401 and the lower support rod 4 move vertically synchronously.

[0022] In the embodiments of the present disclosure, as Figure 4As shown, the middle ejector post 304 is slidably connected to the upper die holder 3. The lower end of the middle ejector post 304 penetrates to the inside of the upper die part 305. The lower positioning ring holder 303 is located outside the upper die part 305. The lower end of the lower connecting frame 302 is rotatably connected to the outer connecting rod 101. The middle support spring 307 supports the synchronous downward movement of the middle ejector post 304 and the lower positioning ring holder 303. The lower positioning ring holder 303 moves downward in advance to perform the positioning operation of assisting in pressing the parts to be stamped below in advance. The middle support spring 307 supports the downward movement of the lower positioning ring holder 303 and the middle ejector post 304. The middle ejector post 304 protrudes into the upper die part 305 to eject the remaining or stuck parts of the upper die part 305 downward. The middle ejector post 304 assists in the operation of exporting the parts of the upper die part 305.

[0023] In the embodiment of the present disclosure, as Figure 6 shown, the two sides of the intermediate gear 201 are respectively engaged with the tail synchronous rack 402 and the outer synchronous rack 306. The tail synchronous rack 402 and the outer synchronous rack 306 move in opposite directions. The head end of the side support rotating frame 403 is rotatably connected to the lower die holder 1. When the upper die part 305 and the lower die part 104 are in contact, the lower die holder 1 remains horizontal. The top of the lower support rod 4 is in contact with the bottom of the lower die holder 1. The upper part of the side support rotating frame 403 is in contact with the bottom of the lower die holder 1. The lower support rod 4 synchronously performs the contact support when the lower die holder 1 is tilted. The lower support rod 4 ensures the supporting force at the suspended position when the lower die holder 1 is tilted. The side support rotating frame 403 synchronously contacts and supports the lower die holder 1 to expand the supporting surface. The side support rotating frame 403 synchronously contacts and supports the lower die holder 1 to expand the supporting surface, enhancing the support for the suspended part of the lower die holder 1.

[0024] In the embodiment of the present disclosure, as Figure 7 shown, when the upper die part 305 and the lower die part 104 move and separate, the lower support rod 4 and the side synchronous support rod 401 move downward away from the lower die holder 1. The lower die holder 1 rotates downward around the center and the rotating shaft of the lower die fixing seat 2 toward the side of the lower support rod 4. After the lower die part 104 and the outer lifting table 103 are tilted, they guide the stamped parts to slide and export to the lower side, eliminating the need for manual removal of parts by hand, shortening the stamping interval, further accelerating the production efficiency, and also eliminating the need for compressed air export. The inclined surface setting better completes the export of parts to the specified range.

[0025] In Embodiment 2, on the basis of Embodiment 1, a compressed air spray outlet is fixed on one side of the outer lifting table 103 and the outer connecting rod 101. The compressed air spray outlet is communicated with a pump. When the outer lifting table 103 is tilted, the compressed air spray outlet is synchronously opened to blow air against the stamped parts, accelerating the removal speed of the stamped parts, and ensuring the correct moving direction while guiding the parts on the inclined surface to improve the moving speed of the parts.

[0026] Working principle of the first embodiment: The lower die holder 1 is fixed on the lower platform of the stamping machine. The upper die holder 3 is bolted to the moving frame of the stamping machine. The stamping machine drives the upper die holder 3 to reciprocate vertically downward. The hole positions of the upper die holder 3 and the positioning slide rod 102 penetrate and slide to assist in positioning the upper die part 305 and the lower die part 104. The aviation part material to be stamped passes through the outer lifting table 103 and the top of the lower die part 104. During the approach of the upper die part 305 and the lower die part 104 for stamping, the middle support spring 307 supports the middle ejector post 304 and the lower positioning ring frame 303 to move downward synchronously. The premature downward movement of the lower positioning ring frame 303 performs a positioning operation of pre-assist pressing on the lower part to be stamped. The premature downward movement of the lower positioning ring frame 303 also resets the lower die holder 1 to the horizontal state. During the continued downward movement of the upper die holder 3, the middle ejector post 304 and the lower positioning ring frame 303 gradually approach the upper die holder 3, and the upper die part 305 and the lower die part 104 are closed for stamping work; During the closing process of the upper die part 305 and the lower die part 104, the upper die holder 3 and the outer synchronous rack 306 move downward synchronously. The outer synchronous rack 306 drives the tail synchronous rack 402 to move upward through the intermediate gear 201. The tail synchronous rack 402 and the outer synchronous rack 306 move in opposite directions through the intermediate gear 201. The lower support rod 4 and the side support rotating frame 403 move closer to the bottom of the lower die holder 1. The lower support rod 4 and the side support rotating frame 403 support the suspended side of the lower die holder 1 when the upper die part 305 and the lower die part 104 are closed, disperse the force on the lower die holder 1 during stamping, improve the stability of the lower die holder 1 during stamping, and reduce the deformation of the suspended side of the lower die holder 1; After the upper die part 305 and the lower die part 104 are separated and moved after stamping and closing, during the upward movement of the upper die part 305, the middle support spring 307 supports the lower positioning ring frame 303 and the middle ejector post 304 to move downward. The middle ejector post 304 protrudes into the upper die part 305 to push out the remaining or stuck parts of the upper die part 305 downward. The outer lifting table 103 can move up and down for buffering. The upward movement of the outer lifting table 103 ensures that the part is at the top of the lower die part 104, avoiding the part being stuck outside the lower die part 104. The upward movement of the outer lifting table 103 pushes the part up to a reasonable position at the top, reduces the difficulty of removing the part after stamping, ensures the subsequent smooth movement of the part, and at the same time, the part moves along the inclined plane, is not easy to deviate, and also avoids the situation that if the compressed gas is exported, the part is still on the die, and if the die falls, it will cause the die to jam; During the upward movement of the upper die module 305, one side of the lower die holder 1 is pulled upward through the lower connecting frame 302 and the outer connecting rod 101. The lower die holder 1 rotates around the connecting rotating shaft of the lower die holder 1 and the lower die fixing base 2. The other sides of the lower die holder 1, the lower die member 104, and the outer lifting table 103 are synchronously inclined to one side. After the lower die member 104 and the outer lifting table 103 are inclined, the guiding member slides out toward the lower side, eliminating the need for manual removal of the component by hand, improving production efficiency and the safety of stamping production. Moreover, the inclination of the lower die holder 1 is driven by the upward movement after the upper die module 305 moves upward for stamping, without the need for additional driving force; During the separation of the upper die module 305 and the lower die member 104, the lower die holder 1 inclines to one side, and the lower support rod 4 and the side support rotating frame 403 move downward synchronously and away from each other, making room for the rotation of the lower die holder 1 to the inclined side downward. The lower support rod 4 synchronously fits and supports when the lower die holder 1 inclines. The lower support rod 4 ensures the supporting force at the suspended position when the lower die holder 1 inclines. The side support rotating frame 403 synchronously fits and supports the lower die holder 1 to expand the supporting surface. The side support rotating frame 403 synchronously fits and supports the lower die holder 1 to expand the supporting surface, reducing the deformation of the lower die holder 1.
