Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 12The utility model provides a technical solution: a multi-station stamping die, including a lower die 1 and a blank 22, a left bracket 20 is fixedly connected to the left side of the lower die 1, a left slide 14 is provided on the surface of the left bracket 20, a top pressing assembly is slidably connected to the left slide 14, a right bracket 2 is fixedly connected to the right side of the lower die 1, a right slide 3 is provided on the surface of the right bracket 2, a right clamping block 4 that can move forward and backward is slidably connected to the right slide 3, the top pressing assembly is used to fix the blank 22 between the right clamping block 4 and the top pressing assembly, the right clamping block 4 is used to drive the blank 22 and the top pressing assembly to move forward and backward, the blank 22 can be horizontally embedded in the right slide 3 and the left slide 14 from the rear end of the lower die 1, and then the top pressing assembly is used to fix the blank 22 between the right clamping block 4 and the top pressing assembly, and then the right clamping block 4 is moved forward and backward to drive the blank 22 to the upper surface of the lower die 1, which is convenient to use.

[0031] Furthermore, a transmission block 7 is fixedly connected to the right side of the right clamping block 4, and a motor 9 is fixedly connected to the right side of the right bracket 2. A transmission screw 8 is coaxially fixedly connected to the output end of the motor 9. The transmission screw 8 movably penetrates the surface of the transmission block 7, and the transmission screw 8 and the transmission block 7 are threadedly connected. By starting the motor 9 to drive the transmission screw 8 to rotate, the transmission block 7 moves back and forth, thereby causing the right clamping block 4 to move back and forth. The upper and lower surfaces of the right clamping block 4 are rotatably connected to the right pulley 5, and the upper and lower walls of the right slideway 3 are cooperated to open a right limiting groove 6 for the right pulley 5 to move back and forth. By setting the right pulley 5, the sliding friction of the right clamping block 4 is converted into rolling friction, which is beneficial to reducing the friction component when the right clamping block 4 moves.

[0032] Furthermore, the top pressing assembly includes a left clamping block 13 and a telescopic plate 12, the left clamping block 13 and the telescopic plate 12 are fixedly connected, the left side of the right clamping block 4 is fixedly connected with a connecting plate 10, and the left side of the connecting plate 10 is provided with a telescopic groove 11 for the telescopic plate 12 to move left and right. By moving the left clamping block 13 to the right, the left clamping block 13 and the right clamping block 4 clamp the material blank 22, thereby fixing the material blank 22.

[0033] Furthermore, the left side of the left bracket 20 is movably connected with a U-shaped component that can move forward and backward, so that it can move forward and backward with the right clamping block 4. The surface of the U-shaped component is fixedly connected with an electric push rod 15, and the telescopic end of the electric push rod 15 is fixedly connected to the left clamping block 13. The electric push rod 15 is used to drive the top pressure component to move left and right. By extending and retracting the electric push rod 15 left and right, the left clamping block 13 is driven to move left and right.

[0034] Furthermore, the U-shaped component includes a mounting frame 16 and two sliding blocks 17. The two sliding blocks 17 are symmetrically fixedly connected to the right side of the mounting frame 16. The right ends of the two sliding blocks 17 are rotatably connected to the left pulley 18. The left surface of the left bracket 20 is provided with a left limiting groove 19 for the left pulley 18 to move forward and backward. The fixed end of the electric push rod 15 is fixedly connected to the right side of the mounting frame 16. By setting the left pulley 18, the sliding friction of the sliding block 17 is converted into rolling friction, which is beneficial to reduce the friction component when the sliding block 17 moves.

[0035] Furthermore, the surfaces opposite to the right bracket 2 and the left bracket 20 are both provided with positioning grooves 21 for the downward movement of the feed embryo 22, and the bottom groove wall surface of the positioning groove 21 is at the same level as the top surface of the lower mold 1. By arranging that the feed embryo 22 does not contact the upper surface of the lower mold 1 when moving, and can only fall downward and be embedded in the positioning groove 21 when it moves to align with the upper opening of the positioning groove 21, so as to fall onto the upper surface of the lower mold 1, it is beneficial to prevent the feed embryo 22 from rubbing against the upper surface of the lower mold 1 when moving, thereby preventing damage.

[0036] Furthermore, it also includes an upper mold 23, a stamping block 24 is provided at the bottom end of the upper mold 23, a stamping groove 25 for the stamping block 24 to be embedded in the top end of the lower mold 1, a positioning rod 26 is fixedly connected to the bottom end of the upper mold 23, and a docking hole 27 for the positioning rod 26 to be embedded in the top end of the lower mold 1.

[0037] The specific scheme is as follows: the worker first puts the blank 22 between the right clamping block 4 and the left clamping block 13, and then starts the electric push rod 15 to extend, so that the left clamping block 13 presses the blank 22 until the left clamping block 13 and the right clamping block 4 clamp the blank 22, and then starts the motor 9 to drive the transmission screw 8 to rotate, the transmission screw 8 rotates to drive the transmission block 7 to move forward, the transmission block 7 moves forward, drives the right clamping block 4 to move forward along the track of the right slide 3, the right clamping block 4 moves to drive the connecting plate 10 to move, and the connecting plate 10 moves to drive the extension rod 15 to extend, so that the left clamping block 13 presses the blank 22 until the left clamping block 13 and the right clamping block 4 clamp the blank 22. The retractable plate 12 moves, and the movement of the telescopic plate 12 drives the left clamping block 13 to move. The movement of the left clamping block 13 drives the electric push rod 15, the mounting frame 16, and the sliding block 17 to move along the track of the left limit groove 19, and drives the blank 22 to move forward. When the blank 22 moves to align with the positioning groove 21, the pressure of the left clamping block 13 on the blank 22 is released, so that the blank 22 is automatically embedded in the positioning groove 21, and then the upper mold 23 is stamped, so that the stamping block 24 stamps the blank 22 and embeds it into the stamping groove 25, completing the stamping of the workpiece.
