[0020] The present invention will be further described below with reference to the accompanying drawings: Example

[0021] Reference Figure 1-3 A sheet metal strip pressing fixture base includes an I-shaped base 1, a U-shaped groove 2, a rotating shaft 7, ejector pin molds 8, and adjusting bolts 10. The vertical plate of the I-shaped base 1 has an upward-facing U-shaped groove 2 that divides the upper surface of the I-shaped base 1 in two. A rotating shaft 7 is rotatably mounted in the U-shaped groove 2. Several ejector pin molds 8 of different sizes are evenly mounted on the circumference of the rotating shaft 7. The top of each ejector pin mold 8 can protrude from the opening of the U-shaped groove 2. When one ejector pin mold 8 protrudes from the opening of the U-shaped groove 2, other ejector pin molds 8 will not protrude from the opening of the U-shaped groove 2, so that the sheet metal strip to be pressed can be placed on the upper surface of the I-shaped base 1. Adjusting bolts 10 are installed on the vertical plate of the I-shaped base 1 to fix the ejector pin molds 8. This design achieves flexible adaptation to sheet metal strips of different specifications through the combination of a rotatable shaft and multiple ejector pin molds of different sizes. At the same time, it enables quick fixing by adjusting bolts, which significantly improves processing efficiency and fixture versatility.

[0022] Specifically, an installation hole 6 is provided through the bottom surface of the I-beam base 1. The installation hole 6 is a waist-shaped hole structure, and the length direction of the hole is consistent with the length direction of the I-beam base 1, which makes it easy to fix the fixture base to the workbench with bolts. The waist-shaped hole design can adapt to the table surface threaded holes with different spacing.

[0023] Specifically, an operating hole 4 is provided through the upper surface of the I-beam base 1. The operating hole 4 is above the adjusting bolt 10. The operating hole 4 is a circular through hole with a diameter of 20mm, which is used to insert an Allen wrench to tighten or loosen the adjusting bolt 10, so as to avoid interference between the tool and the upper surface of the I-beam base.

[0024] Specifically, the vertical plate of the I-beam base 1 has a threaded hole 5, which is connected to the U-shaped groove 2. The adjusting bolt 10 is threadedly connected to the threaded hole 5. The nominal diameter of the threaded hole 5 is M8 and the thread depth is 15mm, which is completely matched with the M8×1.25 specification of the adjusting bolt 10, ensuring that the adjusting bolt 10 has sufficient axial bearing capacity after being screwed in.

[0025] Specifically, the U-shaped groove 2 of the I-shaped base 1 has shaft holes 3 on both sides. The two ends of the rotating shaft 7 are rotatably installed in the corresponding shaft holes 3. The diameter of the shaft hole 3 is 12mm. The rotating shaft 7 is made of 45# steel round shaft with a diameter of 12mm. The surface is hardened to HRC40-45 to ensure both rotational flexibility and sufficient strength.

[0026] Specifically, each ejector mold 8 has a corresponding threaded hole 9 on its circumferential surface. The ejector mold 8 is threaded to one end of the adjusting bolt 10 through the threaded hole 9. The nominal diameter of the threaded hole 9 is M6 and the depth is 10mm. It forms a reliable connection with the M6 ​​threaded section at the end of the adjusting bolt 10 to prevent the ejector mold 8 from moving axially during the processing.

[0027] Specifically, the circumferential surface of the rotating shaft 7 is evenly provided with several threaded holes 311, and the ejector mold 8 is installed in the corresponding threaded holes 311. The threaded holes 311 are M8 threaded holes, and are evenly distributed at intervals of 30mm along the axial direction of the rotating shaft 7. A total of five threaded holes 311 are provided, which can install five different sizes of ejector mold 8 to meet the processing needs of multiple specifications.

[0028] Specifically, the bottom end of the ejector mold 8 is coaxially provided with an integral threaded end 12. The ejector mold 8 is threadedly connected to the corresponding threaded hole 3 11 through the threaded end 12. The threaded end 12 is 12mm long and has a nominal diameter of M8. It forms a fully threaded connection with the threaded hole 3 11. The connection strength meets the requirement that the ejector mold 8 can withstand an axial force of 500N without loosening.

[0029] In this embodiment, during use, the entire fixture base is first fixed to the worktable surface through the mounting holes 6 on the bottom surface of the I-beam base 1. Then, a suitable ejector mold 8 is selected according to the specifications of the sheet metal strip to be processed. Next, the rotating shaft 7 is rotated so that the top of the selected ejector mold 8 is fully exposed vertically from directly above the opening of the U-shaped groove 2. Then, the adjusting bolt 10 is inserted through the threaded hole 5, so that its end enters the threaded hole 9 of the ejector mold 8 and is tightened to achieve axial fixation of the ejector mold 8. Finally, the sheet metal strip can be pressed. This operation process achieves rapid replacement and precise positioning of the ejector mold through modular design, significantly shortening the fixture adjustment time when processing products of different specifications.

[0030] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
