This patent discloses a stamping forming device for hardware parts, including a cross bar, an upper die, a support base, and a lower die. Telescopic support rods are installed at the four corners of the bottom end of the support base, and rollers are installed at the bottom ends of the telescopic support rods. Shock-absorbing columns are uniformly fixed inside the support base. Vertical columns are installed vertically at both ends of the top of the support base, and a cross bar is installed at the top ends of the vertical columns. A control panel is installed on the vertical column at one end of the top of the support base. Electromagnetic slide rails are arranged at both ends of the cross bar, and connecting plates are installed on the electromagnetic slide rails through sliders. Hydraulic telescopic rods are uniformly installed at the bottom end of the connecting plate, and an upper die is installed at the bottom end of the hydraulic telescopic rod. This patent is convenient to fixedly clamp the hardware parts through the positioning plate when the device stamps the hardware parts by installing a sliding cavity and installing a positioning plate inside the sliding cavity through a positioning spring, thereby increasing the stability of stamping.

[0027] During operation: By moving the pressing device 2 downward, the long plate to be stamped can be stamped into the shape of the required hardware part. When the pressing device 2 moves downward, it can drive the first support frame 41 to move downward. When the first support frame 41 moves downward, the first support frame 41 can drive the first support rod 42 to move downward. When the first support frame 41 drives the first support rod 42 to move downward, the first support rod 42 can drive the long column 43 to rotate around the first support rod 42. When the long column 43 rotates around the first support rod 42, the long column 43 can drive the first long rod 45 to move away from the lower pressing plate 3. When the long column 43 drives the first long rod 45 to move away from the lower pressing plate 3, the first support plate 48 is used to limit the first long rod 45 to move only in the horizontal direction. When the first long rod 45 moves in the horizontal direction, the first long rod 45 will drive the push plate 49 to move away from the lower pressing plate 3. When the first long rod 45 drives the push plate 49 to move away from the lower pressing plate 3, the first long rod 45 will drive the scraping plate 410 to move away from the lower pressing plate 3. After the pressing device 2 moves completely downward, the bottom of the pressing device 2 will be attached to the top of the lower pressing plate 3 through the long plate. When the pressing device 2 moves upward, the long plate will stay on the lower top surface of the lower pressing plate 3, and the stamped hardware part will stay on the top surface of the lower pressing plate 3. When the pressing device 2 moves upward, it can drive the first support frame 41 to move upward. When the first support frame 41 moves upward, the first support frame 41 can drive the first support rod 42 to move upward. When the first support frame 41 drives the first support rod 42 to move upward, the first support rod 42 can drive the long column 43 to rotate around the first support rod 42. When the long column 43 rotates around the first support rod 42, the long column 43 can drive the first long rod 45 to move closer to the lower pressing plate 3. When the long column 43 drives the first long rod 45 to move closer to the lower pressing plate 3, the first support plate 48 is used to limit the first long rod 45 to move only in the horizontal direction. When the first long rod 45 moves in the horizontal direction, the first long rod 45 will drive the push plate 49 to move closer to the lower pressing plate 3. When the first long rod 45 drives the push plate 49 to move closer to the lower pressing plate 3, the first long rod 45 will drive the scraping plate 410 to move closer to the lower pressing plate 3. When the first long rod 45 drives the push plate 49 and the scraping plate 410 to move closer to the lower pressing plate 3, the push plate 49 will push the stamped hardware part into the feeding port 58 through the sliding plate 59.

[0028] When the long column 43 drives the first long rod 45 to move away from the lower pressing plate 3, the long column 43 also drives the second long rod 47 to lift upward. When the long column 43 drives the second long rod 47 to lift upward, the second long rod 47 contacts the third long rod 51. When the second long rod 47 contacts the third long rod 51, the second long rod 47 drives the third long rod 51 to move upward. When the second long rod 47 drives the third long rod 51 to move upward, the third long rod 51 drives the first retaining plate 53 and the second retaining plate 57 to rise. When the third long rod 51 drives the first retaining plate 53 and the second retaining plate 57 to rise, the first retaining plate 53 and the second retaining plate 57 push the long plate on the upper surface of the lower pressing plate 3 upward. When the first retaining plate 53 and the second retaining plate 57 push the long plate on the upper surface of the lower pressing plate 3 upward, the second spring 510 at the bottom of the first elastic plate 56 assists the first retaining plate 53 and the second retaining plate 57 to push the long plate upward. When the long plate is pushed upward by the first retaining plate 53 and the second retaining plate 57, the fourth spring 611 drives the second elastic plate 69 to rise. When the fourth spring 611 drives the second elastic plate 69 to rise, the second elastic plate 69 drives the second support rod 610 to rise. When the second elastic plate 69 drives the second support rod 610 to rise, the second support rod 610 drives the roller 612 to lift. When the roller 612 lifts, the roller 612 drives the second gear 615 to rise. When the roller 612 drives the second gear 615 to rise, the second gear 615 contacts and meshes with the first gear 64. When the second gear 615 contacts and meshes with the first gear 64, the motor 62 drives the first gear 64 and the second gear 615 to rotate. When the first gear 64 and the second gear 615 rotate, they drive the roller 612 to rotate. When the roller 612 rotates, the roller 612 transports the long plate on top of it towards the lower pressing plate 3. When the roller 612 transports the long plate on top of it towards the lower pressing plate 3, the edge of the long plate contacts the second baffle 66. When the edge of the long plate contacts the second baffle 66, the third spring 67 and the second baffle 66 continuously push the long plate towards the central part. At this time, the third spring 67 and the second baffle 66 play a guiding role. When the first retaining plate 53 and the second retaining plate 57 continue to push the long plate upward, the upper surface of the long plate contacts the inner upper surface of the first baffle 54. When the upper surface of the long plate contacts the inner upper surface of the first baffle 54, the long plate is fixed at this time. When the long plate completely passes through the roller 612, the fourth spring 611 drives the second elastic plate 69 to rise. When the fourth spring 611 drives the second elastic plate 69 to rise, the second elastic plate 69 drives the roller 612 to rise. When the roller 612 rises, the roller 612 drives the second gear 615 to rise. When the second gear 615 rises, the second gear 615 contacts one end of the L-shaped plate 65. When the second gear 615 contacts one end of the L-shaped plate 65, one end of the L-shaped plate 65 is lifted by the second gear 615. When one end of the L-shaped plate 65 is lifted by the second gear 615, the other end of the L-shaped plate 65 will drop accordingly. When the other end of the L-shaped plate 65 drops, the other end of the L-shaped plate 65 contacts the main switch 613. When the other end of the L-shaped plate 65 contacts the main switch 613,The machine will stop working to prevent damage to the machine.
