Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see the appendix Figure 1-6 This application provides the following technical solutions. Example

[0026] An adjustable-length forging die for a large-end shaft includes a large-end die base 1 and an end die base 2, which are arranged opposite to each other. A length-customizing component is provided between the large-end die base 1 and the end die base 2. The length-customizing component includes several customized extension modules 4 arranged in a ring. Positioning grooves 3 are provided on opposite sides of both the large-end die base 1 and the end die base 2. Two arc-shaped sliders 5 are symmetrically provided on both sides of the several customized extension modules 4. The two arc-shaped sliders 5 are respectively movably inserted into the positioning grooves 3 of the large-end die base 1 and the end die base 2, and the inner circumference of the ring formed by the several customized extension modules 4 is flush with the inner circumference of the large-end die base 1 and the end die base 2. The surfaces are flush. A filling groove 6 is provided through one side of the positioning slide groove 3 of the large head mold base 1 and the end mold base 2. The width of the filling groove 6 is greater than the width of the arc-shaped slider 5. After several customized extension modules 4 are connected to the large head mold base 1 and the end mold base 2, the arc-shaped slider 5 and the filling groove 6 are staggered. When it is necessary to adjust the length of the mold, the length of the entire mold can be changed by replacing the customized extension modules 4 of different heights. When replacing, the cooperative design of the positioning slide groove 3 and the arc-shaped slider 5 can quickly position the customized extension module 4, ensuring quick and convenient operation. At the same time, it maintains stable lateral support when the customized extension module 4 is subjected to internal impact.

[0027] When the adjustable fixing component is used to replace the customized extension module 4 between the large-end mold base 1 and the end mold base 2, or after the replacement, the large-end mold base 1, the end mold base 2, and the customized extension module 4 are fixed. The adjustable fixing component is located on the outer periphery of the large-end mold base 1 and the end mold base 2. The adjustable fixing component includes several high-strength screws 8 and several combined guide sleeves 7, with the combined guide sleeves 7 and the high-strength screws 8 correspondingly arranged. Several large-end mold bases 1 are provided with large-end flanges, and several high-strength screws 8 are vertically and symmetrically arranged at the lower end of the large-end flanges of the large-end mold base 1, with the high-strength screws 8 offset from the filling groove 6. The end mold base... The outer periphery of 2 is vertically provided with several installation clearance grooves 9, and several combined guide sleeves 7 are respectively set with several installation clearance grooves 9. The center of the combined guide sleeve 7 is provided with a matching guide hole, and the lower end of the high-strength screw 8 is movably passed through the matching guide hole and is provided with a fixing nut 10 through the threaded sleeve. By loosening or tightening the fixing nut 10, the distance between the large head mold base 1 and the end mold base 2 can be realized to accommodate customized extended modules 4 of different sizes. At the same time, the tightening operation of multiple fixing nuts 10 and high-strength screw 8 can be used to press and fix the customized extended module 4 through the large head mold base 1 and the end mold base 2.

[0028] When it is necessary to replace the customized extension module 4, first slightly loosen the fixing nut 10, place it horizontally or lift the large end mold base 1 and the end mold base 2 individually so that the customized extension module 4 can slide in the positioning groove 3 through the arc slider 5. When the arc slider 5 is aligned with the filling groove 6, pull out the customized extension module 4 from the side. Take out the remaining customized extension modules 4 in the same way. Then adjust the gap between the large end mold base 1 and the end mold base 2, insert the arc slider 5 into the positioning groove 3 from the position of the filling groove 6 of the customized extension module 4 to be replaced, and finally keep the arc slider 5 and the filling groove 6 misaligned, and press and fix the multiple high-strength screws 8 and fixing nuts 10.

[0029] In addition, to ensure the connection strength between the large head mold base 1 and the end mold base 2, the number of high-strength screws 8 and combined guide sleeves 7 can be customized as needed based on the force analysis. Similarly, after the number of high-strength screws 8 and combined guide sleeves 7 is increased, in order to ensure that the customized extended module 4 can be inserted from the side between the large head mold base 1 and the end mold base 2, the width of the customized extended module 4 and the arc-shaped slider 5 also needs to be adjusted accordingly.

[0030] A stabilizing assembly is installed to maintain the connection and fixation between the large-head mold base 1 and the end mold base 2. The stabilizing assembly is mounted on the high-strength screw 8 and includes several auxiliary abutment plates 12. Each end mold base 2 has a horizontally opening telescopic groove 11 on one side of the mounting clearance groove 9. The auxiliary abutment plates 12 are horizontally placed within the telescopic grooves 11, with one side of each plate penetrating the telescopic groove 11 and inserting into the mounting clearance groove 9. The side of each auxiliary abutment plate 12 within the mounting clearance groove 9 rubs against one side of the fixing nut 10, and the side of the auxiliary abutment plate 12 away from the fixing nut 10 is inclined. A spring guide rod 13 is horizontally positioned at the center of the telescopic groove 11. A clearance hole 15 is horizontally opened on the side of each auxiliary abutment plate 12 near the spring guide rod 13, and the side of the spring guide rod 13 is movably inserted into the clearance hole 15. Within 5, a retaining spring 14 is sleeved on one side of the spring guide rod 13 located within the telescopic groove 11. When the fixing nut 10 and the high-strength screw 8 pass through one side of the combined guide sleeve 7, the fixing nut 10 and one side of the combined guide sleeve 7 are pressed together. At this time, under the elastic force of the retaining spring 14, the auxiliary abutment plate 12 extends out and makes tight frictional contact with the side of the fixing nut 10 away from the combined guide sleeve 7. Thus, under the dual strengthening effect of the upper and lower friction of the combined guide sleeve 7 and the auxiliary abutment plate 12, the fixing nut 10 strengthens and maintains a stable posture, thereby achieving stable connection between the large head mold base 1 and the end mold base 2. The side of the fixing nut 10, the combined guide sleeve 7 and the auxiliary abutment plate 12 that are in contact can be provided with anti-slip texture to improve the contact stability between the fixing nut 10 and the combined guide sleeve 7 and the auxiliary abutment plate 12.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
