[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0033] Refer to Figure 1 、 Figure 2 and Figure 4, an embodiment provided by the present invention: a continuous stamping device for hardware parts with rapid prototyping, including a base 1. A workbench 3 is fixedly connected to the top wall of the base 1. Support columns 4 are fixedly connected to the four corners of the top wall of the base 1. An installation block 20 is installed in the middle of the top wall of the workbench 3. A fixed block 28 is fixedly connected to the middle of the inner wall of the installation block 20. A bottom block 33 is fixedly connected to the right side of the inner bottom wall of the installation block 20. A motor 32 is installed on the top of the bottom block 33. The output end of the motor 32 is fixedly connected to a gear 34. A rack 31 is meshed and connected to the left side of the gear 34. The rack 31 is slidably connected to the inner wall of the fixed block 28. Limit blocks 35 are installed at the front and rear ends of the gear 34. The limit blocks 35 are fixedly connected to the front and rear ends on the right side of the fixed block 28. The top end of the rack 31 is fixedly connected to a bottom plate 25. Slide columns 24 are fixedly connected to the four corners of the top wall of the bottom plate 25. The outer walls of a plurality of slide columns 24 are all slidably connected to an installation plate 23. A top plate 22 is fixedly connected to the middle of the top wall of the installation plate 23. A plurality of clamping blocks 27 are fixedly connected to the left and right sides of the top wall of the bottom plate 25 at equal intervals. A two-way pulley 26 is rotatably connected to the inner wall of the clamping block 27. A plurality of first chutes 29 are equidistantly opened on the left and right sides of the inner wall of the installation block 20. The first chutes 29 are slidably connected to the two-way pulley 26. A bottom die 21 is fixedly connected to the middle of the top wall of the installation block 20. The motor 32 drives the gear 34 to rotate, and then the gear 34 drives the rack 31 to slide up and down in the inner wall of the fixed block 28. When the rack 31 slides upward, it will lift the bottom plate 25. The bottom plate 25 lifts the installation plate 23 to move upward, so that the top plate 22 first lifts the die. When the two-way pulley 26 slides to the upper limit of the first chute 29, one side of the two-way pulley 26 will move downward, and the two-way pulley 26 rotates on the clamping block 27 so that the other side will lift the top plate 22 again, realizing that during the process of the die separating from the bottom die 21, the uneven resistance force on different parts is reduced, resulting in deformation and cracking defects. Fixing plates 17 are fixedly connected to the front and rear sides of the top wall of the workbench 3. A wire 11 is installed on the right side of the outer wall of the workbench 3. A controller 10 is installed at the end of the wire 11. A second chute 16 is installed on the inner side of the bottom of the fixing plate 17. A clamping mechanism 2 is installed on the inner side of the fixing plate 17. The clamping mechanism 2 is used to fixedly clamp the die. Two hinges 9 are installed at the left and right ends of the front side of the outer wall of the workbench 3. A maintenance door 6 is fixedly connected to the rear side of a plurality of hinges 9. The hinge 9 serves as a connecting component, providing a basis for the subsequent installation and movement of the maintenance door 6. Handles 8 are fixedly connected to the left and right ends of the front side of the outer wall of the maintenance door 6. Anti-slip sleeves 7 are rotatably connected to the outer sides of the two handles 8. Users can apply force by holding the handles 8. Compared with directly pushing and pulling the maintenance door 6, the operation is more labor-saving and convenient, and at the same time, the opening and closing actions of the maintenance door 6 can be better controlled. When the user holds the handle 8, the anti-slip sleeve 7 can prevent the hand from slipping due to sweating and uneven force, ensuring the safety and stability of the operation process;

[0034] Specifically, the motor 32 drives the gear 34 to rotate, and then the gear 34 drives the rack 31 to slide up and down on the inner wall of the fixed block 28. When the rack 31 slides upward, it will lift the bottom plate 25, and through the bottom plate 25, the mounting plate 23 is lifted upward, causing the top plate 22 to lift the mold for the first time. When the two-way pulley 26 slides to the upper limit of the first chute 29, one side of the two-way pulley 26 will face downward, and the two-way pulley 26 rotates on the clamping block 27 so that the other side will lift the top plate 22 again, realizing that during the process of the mold detaching from the bottom mold 21, the uneven resistance force on different parts is reduced, thus avoiding deformation and cracking defects.

[0035] Referring to Figure 1 , Figure 5 and Figure 6 , the clamping mechanism 2 includes a square plate 201, which is installed inside the fixed plate 17. In the middle of the front wall of the square plate 201, a rotating shaft 204 is fixedly connected. A connecting block 205 is rotatably connected to the outside of the rotating shaft 204. At the upper and lower ends of the front side of the connecting block 205, bolts 209 are fixedly connected. The outer walls of the two bolts 209 are rotatably connected with connecting pieces 206. The outer walls of the two connecting pieces 206 are rotatably connected with bolts 209. At the upper and lower ends of the front side of the square plate 201, slide rails 203 are fixedly connected. The outer walls of the two slide rails 203 are slidably connected with sliders 207. The top of the slider 207 is fixedly connected with a long plate 208. In the upper middle part of the front side of the long plate 208, a clamping plate 210 is fixedly connected. The bolt 209 is rotatably connected to the middle part of the outer wall of the long plate 208. At the front and rear ends of the right long plate 208, telescopic rods 202 are installed. The telescopic rods 202 push and pull the long plate 208, causing the slider 207 under the long plate 208 to slide outward on the slide rail 203. The bolt 209 under the slider 207 stretches the connecting piece 206, and the connecting piece 206 rotates on the rotating shaft 204 of the connecting block 205. The rotation of the connecting block 205 drives the simultaneous stretching of the right connecting piece 206, causing the long plate 208 and the clamping plate 210 to move outward simultaneously. By the simultaneous movement of the long plate 208, the clamping plate 210 clamps and fixes the hardware parts to be stamped. The top end of the support column 4 is fixedly connected with a press 5, which provides the power and pressure required for stamping. The bottom end of the press 5 is fixedly connected with an upper pressing die 30. On the right side of the outer wall of the press 5, a connecting pipe 15 is installed, and the end of the connecting pipe 15 is installed with a hydraulic chamber 12;

[0036] Specifically, the telescopic rods 202 push and pull the long plate 208, causing the slider 207 under the long plate 208 to slide outward on the slide rail 203. The bolt 209 under the slider 207 stretches the connecting piece 206, and the connecting piece 206 rotates on the rotating shaft 204 of the connecting block 205. The rotation of the connecting block 205 drives the simultaneous stretching of the right connecting piece 206, causing the long plate 208 and the clamping plate 210 to move outward simultaneously. By the simultaneous movement of the long plate 208, the clamping plate 210 clamps and fixes the hardware parts to be stamped.

[0037] Reference Figure 1 , Figure 2 and Figure 3 , a dashboard 14 is installed at the front end of the top wall of the hydraulic chamber 12, a hydraulic pump 13 is installed at the rear side of the dashboard 14, a plurality of bases 19 are installed on both the left and right sides of the mounting block 20, and a conveyor belt 18 is installed on the top of the base 19;

[0038] Specifically, the dashboard 14 displays key parameters such as the stamping pressure of the press 5, the oil pressure of the hydraulic system, the feeding speed and length of the feeding mechanism, and the real-time temperature of the equipment operation, enabling the operator to intuitively understand the equipment operation status. The hydraulic pump 13 converts mechanical energy into hydraulic energy and provides pressure oil for the actuators of the press 5 to drive them to complete the stamping action. A plurality of bases 19 are installed on both the left and right sides of the mounting block 20, and a conveyor belt 18 is installed on the top of the base 19. The conveyor belt 18 accurately feeds the raw materials into the mold for stamping.

[0039] Working principle: The motor 32 drives the gear 34 to rotate, and then the gear 34 drives the rack 31 to slide up and down on the inner wall of the fixed block 28. When the rack 31 slides upward, it will lift the bottom plate 25, and through the bottom plate 25, the mounting plate 23 is lifted upward to make the top plate 22 lift the mold for the first time. When the bidirectional pulley 26 slides to the upper limit of the chute 1 29, one side of the bidirectional pulley 26 will move downward, and the bidirectional pulley 26 rotates on the clamping block 27 to make the other side lift the top plate 22 again, realizing the process of reducing the uneven resistance force on different parts and preventing deformation and cracking defects during the process of the mold separating from the bottom mold 21;

[0040] The telescopic rod 202 pushes and pulls the long plate 208, so that the slider 207 under the long plate 208 slides outward on the slide rail 203. The bolt 209 under the slider 207 stretches the connecting piece 206, and the connecting piece 206 rotates on the rotating shaft 204 of the connecting block 205. The rotation of the connecting block 205 drives the connecting piece 206 on the right side to stretch simultaneously, so that the long plate 208 and the clamping plate 210 move outward simultaneously. The simultaneous movement of the long plate 208 enables the clamping plate 210 to clamp and fix the hardware parts to be stamped.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
