[0013] The upper mold plate 1 is set as a rectangular parallelepiped structure, and is connected to the upper mold plate 5 through a cylindrical pin 2 and a hexagon socket bolt Ⅰ4; the mold handle 3 is set as a stepped rotating body structure, and is connected to the upper mold plate 1 by an interference fit; the upper mold plate 5 is set as a V-shaped composite curved surface structure, and is connected to the upper mold plate 1 through a hexagon socket bolt Ⅰ4 and a cylindrical pin 2;

[0014] The lower template 19 is set as a rectangular parallelepiped structure, and is connected to the lower pressing block 18 through the hexagon socket bolt III 13, the positioning shaft 16, and the positioning guide shaft 17; the lower pressing block 18 is set as a trapezoidal structure, the upper end of the top surface is provided with an arc surface, a V-shaped composite curved surface structure groove is provided in the middle, pin holes are provided on both sides, and step holes and thread holes are provided on the back;

[0015] The side baffle 11 is set as a rectangular parallelepiped structure, with a square hole in the middle and an inclined surface structure at the top, and is connected to the lower pressing block 18 by a hexagon socket bolt II 12;

[0016] The lower pressing block 18 is set as a rectangular parallelepiped structure, with through holes and thread holes respectively set on the upper part and thread holes set on the side; the positioning shaft 16 is set as a cylindrical structure; the lower part of the positioning guide shaft 17 is set as a cylindrical structure, and the upper part is set as a conical step structure.

[0017] The upper pressing block 5V-shaped composite curved surface structure is set as an R105 large arc curved surface in the length direction of the forming surface, a 117° V-shaped angle is set in the width direction, and an 18° inclined surface is set on the side; the top surface is set as a plane, and thread holes and pin holes are set.

[0018] The lower pressing block 18 has a trapezoidal structure, which is narrow on the left and wide on the right. An arc surface R105 is arranged at the upper end of the top surface, and a V-shaped composite curved surface structure groove is opened in the middle. The length direction of the V-shaped composite curved surface structure groove is set to R106.7, and the width direction is set to a 117° V-shaped angle.

[0019] The side baffle 11 is configured as a rectangular parallelepiped structure, with a square hole in the middle and a slope structure on the top. The slope structure is configured with a depth of 20 mm and an angle of 8.5° in the width direction, and an R2 fillet is configured on the top.

[0020] The lower part of the positioning guide shaft 17 is set as a cylindrical structure, and the upper part is set as a conical step structure. The top of the conical step structure is set with a column base with a height of 10mm and an outer diameter of φ16mm, and the cone angle is set to 9.8°.

[0021] During production, first close the furrow opener rake tooth profiling die and place it on the punching machine workbench and move it to the approximate working area. Then adjust the punching machine flywheel, adjust the punching machine slider to the top dead center position, and adjust the screw to adjust the connecting rod length to the shortest. Fine-tune the mold position, align the mold handle with the slider hole, and slowly move the slider down through the inching mode until the lower plane of the slider is close to the upper plane of the upper template, and then tighten the fixing screw to fix the upper mold on the slider. Start the punching machine and let the slider stop at the top dead center position. Add lubricating oil to the guide column 15, run the equipment dry 2-3 times, and rely on the adjustment of the guide column 15 and the guide sleeve 14 to automatically align the upper template 1 and the lower template 19, and then press the lower mold. Adjust the appropriate die height by fine-tuning the connecting rod length. After everything is normal, start putting in the blank 6 for punching.

[0022] Stamping process: The slider on the 25-ton punching machine drives the upper die of the mold to move downward as a whole. The two sides of the V-shaped composite surface of the upper pressure block 5 first contact the sheet 6, and the sheet 6 begins to deform in a V shape. The small end of the sheet 6 is always in contact with the positioning guide shaft 17 under the V-shaped deformation to avoid displacement. The sheet 6 undergoes arc deformation during the stamping stroke until the stamping is completed. During the mold return stroke, the sheet 6 is ejected by the ejector pin 7 after being formed, slides out of the mold along the square hole of the side baffle 11, and then continues the next working cycle.

[0023] The beneficial effects of the utility model are that the furrow opener rake tooth pressing mold not only improves the processing efficiency of the product, but also ensures the dimensional accuracy and beautiful appearance of the product.
