[0035] Buffering assembly is arranged between the movable end of the hydraulic cylinder 3 and the upper die 4.
[0036] Ejection mechanism is arranged at the bottom of the base 1, and is used for ejecting the stamped parts.

[0038] The utility model discloses through die fixing assembly improves the accuracy of die positioning, has reduced the scrap rate, through buffering assembly has reduced the impact of stamping to equipment, has prolonged hydraulic cylinder 3 service life through ejection assembly makes blanking more convenient, has improved production efficiency.
[0039] Further optimization scheme, the die fixing mechanism includes first clamping assembly and second clamping assembly, first clamping assembly and second clamping assembly are perpendicular and are staggered up and down, and first clamping assembly and second clamping assembly are arranged on the outside of the lower die 2.
[0040] First clamping assembly and second clamping assembly are respectively centered and clamped from the front and rear and the left and right sides of the lower die 2, regardless of the size of the lower die 2, the lower die 2 is always located at the center position of the workbench 101 and corresponds to the upper die 4.
[0041] Further optimization scheme, the first clamping assembly includes a bidirectional screw 5 and a guide rod 6, the bidirectional screw 5 and the guide rod 6 are respectively rotatably connected to the two sides of the top surface of the workbench 101, the bidirectional screw 5 is symmetrically screw-connected with a clamping plate 7 at both ends, and the two clamping plates 7 are slidably connected with the guide rod 6 at the ends away from the bidirectional screw 5; one end of the bidirectional screw 5 extends out of the workbench 101 and is drivingly connected with a motor 8.
[0042] The motor 8 drives the bidirectional screw 5 to rotate, and under the guidance of the guide rod 6, the clamping plates 7 are close to or away from each other, and then the lower die 2 between the two clamping plates 7 is clamped or relaxed.
[0043] Further optimization scheme, the second clamping assembly is the same as the first clamping assembly in structure, the top surface of the workbench 101 is provided with a placing groove 9, the lower die 2 is placed in the placing groove 9, and the second clamping assembly is fixedly installed in the placing groove 9.
[0044] The second clamping assembly is installed in the placing groove 9, and the first clamping assembly is installed on the workbench 101, so that the first clamping assembly and the second clamping assembly are staggered up and down, and interference is avoided.

When it receives a thrust from the bottom, the bottom surface 201 of the die can push the part up and away from the die body 202, making it easier to remove the part.
[0049] Further optimization of the scheme: the ejection mechanism includes an ejection cylinder 14, which is fixedly connected to the center below the machine base 1. In the retracted state, the movable end of the ejection cylinder 14 is flush with the top surface of the worktable 101, and the movable end of the ejection cylinder 14 corresponds to the bottom surface 201 of the mold.

After the stamping of the part is completed, ejector cylinder 14 extends, so that the bottom surface 201 of the die is separated from the die body 202, thereby making it easy to remove the stamped part.
[0051] The design has been further optimized by fixing several shock-absorbing pads 15 to the bottom of the base 1.
