[0043] Combined with Figures 1 to 6 As shown, the automatic die forging line forming device for shaft forgings includes a base 1, a lower die 2, an upper die 3, a first adjusting member 4, and a second adjusting member 5.

[0044] The lower die 2 is slidably arranged on both sides of the upper part of the base 1, and a cavity 21 is formed between the two lower dies 2; the upper die 3 is embedded in the cavity 21; the first adjusting member 4 is threadedly arranged on both sides of the base 1, and one end of the first adjusting member 4 is rotatably sleeved on the lower die 2. The first adjusting member 4 is used to adjust the distance between the two lower dies 2 to form cavities 21 of different specifications and sizes; the second adjusting member 5 is arranged on both sides of the upper die 3, and the second adjusting member 5 is used to adapt to cavities 21 of different specifications and sizes.

[0045] Among them, by slidably arranging the lower die 2 on both sides of the upper part of the base 1, and respectively arranging the first adjusting member 4 on both sides of the base 1, under the action of the first adjusting member 4, the distance between the two lower dies 2 can be changed, thereby adjusting the size of the cavity 21, realizing the adaptive forging of shaft parts of different sizes. This design enables the flexible adjustment of the size of the cavity 21 according to the size of the forging parts required; by respectively arranging the second adjusting member 5 on both sides of the upper die 3, under the action of the second adjusting member 5, the cavities 21 of different specifications and sizes can be effectively matched, which means that the upper die 3 can also be adjusted according to actual needs to ensure that it matches the size of the adjusted cavity 21, so as to better complete the forging process.

[0046] Adjusting method:

[0047] According to the size of the required shaft parts, first rotate the first adjusting member 4 to adjust the distance between the two lower dies 2 to form a suitable size of the cavity 21. Then, according to the adjusted size of the cavity 21, adjust the position of the upper die 3 through the second adjusting member 5 to ensure its matching with the size of the cavity 21.

[0048] Combined with Figure 3 and Figure 5 As shown, the first adjusting member 4 includes: an adjusting screw 41, a limiting block 42 and a driving handle 43. The adjusting screw 41 is sleeved on the base 1, one end of the adjusting screw 41 extends into the lower die 2, and a limiting block 42 is arranged, and the limiting block 42 is rotatably arranged in the lower die 2; the driving handle 43 is arranged at the other end of the adjusting screw 41; a limiting groove 22 is formed on one side of the lower die 2, one end of the adjusting screw 41 passes through the lower die 2 and extends into the limiting groove 22, and is connected with the limiting block 42, and the limiting block 42 is rotatably arranged in the limiting groove 22.

[0049] Among them, the operator drives the adjusting screw 41 to rotate by rotating the driving handle 43. The rotation of the adjusting screw 41 drives the limiting block 42 to rotate in the limiting groove 22. The rotation of the limiting block 42 makes the lower die 2 move along the direction of the base 1, realizing the adjustment of the size of the cavity 21. Through this design, the position of the lower die 2 can be accurately controlled, and the size of the cavity 21 can be flexibly adjusted, so as to meet the forging requirements of shaft parts of different sizes.

[0050] Combined withFigure 1 and Figure 4 As shown in Figure 4 , mounting cavities 31 are respectively formed on both sides of the upper die 3. The second adjusting member 5 is disposed in the mounting cavity 31. The second adjusting member 5 includes: a spring 51 and a sealing block 52. A plurality of springs 51 are arranged along the height direction of the mounting cavity 31; on one side of the spring 51 is the sealing block 52, and one side of the sealing block 52 is in contact with the inner side wall of the cavity 21.

[0051] Among them, the main function of the mounting cavity 31 is to accommodate the second adjusting member 5. When the size of the cavity 21 changes, by adjusting the number or stiffness of the springs 51 in the second adjusting member 5, the pressure of the sealing block 52 on the inner side wall of the cavity 21 can be changed. Under the action of the spring 51, the sealing block 52 closely fits the inner side wall of the cavity 21, ensuring good sealing and cooperation between the upper die 3 and the cavity 21. Through this design, cavities 21 of different specifications can be effectively matched, ensuring good cooperation between the upper die 3 and the cavity 21, and improving the accuracy and consistency in the forging process.

[0052] Combined with Figure 1 、 Figure 2 and Figure 5 As shown in Figure 1 , Figure 2 and Figure 5 , a slide rail 11 is formed on the upper part of the base 1; a slider 23 is provided at the lower part of the lower die 2, and the slider 23 is slidably embedded in the slide rail 11.

[0053] Among them, when the position of the lower die 2 needs to be adjusted, the position of the lower die 2 is changed by the adjusting screw 41 in the first adjusting member 4. Under the action of the adjusting screw 41, the limiting block 42 drives the lower die 2 to move along the slide rail 11 to realize the adjustment of the size of the cavity 21. The sliding fit between the slider 23 and the slide rail 11 ensures the smoothness and accuracy of the movement of the lower die 2. Through the interaction between the slide rail 11 and the slider 23, the stability and accuracy of the lower die 2 during the adjustment process can be ensured, and the accuracy of the size adjustment of the cavity 21 is improved.

[0054] Further combined with Figure 2 As shown in Figure 2 , scale lines 12 are respectively engraved on both sides of the base 1, and the scale lines 12 are located below the slide rail 11. The main function of the scale lines 12 is to provide an intuitive position reference for the operator, helping them accurately adjust the position of the lower die 2, so as to realize the precise adjustment of the size of the cavity 21. By observing the scale lines 12, the operator can quickly judge the position of the lower die 2 relative to the base 1 to ensure that the size of the cavity 21 meets the expected requirements. Usually, the scale lines 12 are engraved at a certain interval, for example, one scale line is set every certain distance (such as 1 mm, 2 mm, etc.) for accurate measurement and positioning.

[0055] Among them, when it is necessary to adjust the position of the lower die 2, the operator can determine the current position of the lower die 2 by observing the scale line 12. According to the required size of the cavity 21, the operator can adjust the position of the lower die 2 through the adjusting screw 41 in the first adjusting member 4. During the adjustment process, the operator can observe the scale line 12 at any time to ensure that the position of the lower die 2 accurately reaches the required position, thereby achieving precise adjustment of the size of the cavity 21.

[0056] Combined with Figure 6 As shown, fixed pressure rings 32 are provided on both sides of the upper die 3. The main function of the fixed pressure rings 32 is to ensure a reliable connection between the upper die 3 and the second adjusting member 5, preventing loosening or displacement during the forging process. Through the fixed pressure rings 32, the second adjusting member 5 can be firmly fixed on both sides of the upper die 3, ensuring a good fit between the upper die 3 and the cavity 21.

[0057] Combined with Figure 5 As shown, the lower die 2 includes: a first lower die body 24 and a second lower die body 25. The first lower die body 24 is slidably disposed on both sides of the upper part of the base 1 and is rotatably connected to the first adjusting member 4; the second lower die body 25 is clamped on the upper part of the first lower die body 24, and the upper die 3 is embedded between the two second lower die bodies 25. By clamping the second lower die body 25 on the upper part of the first lower die body 24, the characteristics of being convenient for disassembly and replacement between the first lower die body 24 and the second lower die body 25 can be realized, improving the maintainability and flexibility of the equipment.

[0058] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
