Description

Technical Field

[0001] The utility model relates to the technical field of half axle tube head processing, in particular to a forging die device for high-precision half axle tube heads. Background Technique

[0002] A high-precision half axle tube head is a key component of an automotive transmission system, usually used to transmit power and torque. Its manufacturing process has very strict requirements to ensure the dimensional accuracy, surface quality and mechanical properties of the product. High-precision half axle tube heads usually use high-quality alloy steels such as 40Cr, 45 steel or other materials with high strength and wear resistance. The forging die device provides the required strong pressure during the manufacturing process to ensure that the metal is accurately formed in the die.

[0003] When manufacturing a half axle tube head, first heat the metal blank to a suitable temperature for forging. Then, quickly transfer the heated blank to the lower die. Start the hydraulic forging machine or mechanical press to move the upper die down and close it with the lower die to complete the forging.

[0004] After forging, the casting needs to be demolded. The traditional demolding method is to manually strike the die or the casting with a hammer or other tools to separate the casting from the die. Although this method can complete the demolding operation, since the force and direction of manual striking are difficult to ensure consistency, it may cause surface damage, deformation or residual striking marks on the casting, thereby affecting the appearance and performance of the product. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a forging die device for high-precision half axle tube heads, aiming to improve the problem in the prior art that due to the difficulty in ensuring the consistency of the force and direction of manual striking, it may cause surface damage, deformation or residual striking marks on the casting.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Refer to Figure 1 , Figure 2 and Figure 3, an embodiment provided by the present utility model: a forging die device for a high-precision half axle tube head, including a base 1, a die table 2 is fixedly connected to the upper part of the base 1, a lower die 28 is fixedly connected to the upper part of the die table 2, fixing columns 3 are fixedly connected to both sides of the upper part of the die table 2, a mounting plate 4 is fixedly connected to the outside of the two fixing columns 3, a hydraulic cylinder 5 is fixedly connected to the inside of the mounting plate 4, a cross plate 7 is fixedly connected to the output end of the hydraulic cylinder 5, a mounting block 8 is fixedly connected to the lower part of the cross plate 7, a mounting cavity 11 is provided inside the mounting block 8, a replacement component 12 is arranged inside the mounting cavity 11, and the replacement component 12 is used for replacing the worn die. A mounting post 9 is inserted into the mounting block 8, an upper die 10 is fixedly connected to the bottom of the mounting post 9, a fixing plate 16 is fixedly connected to the lower part of the die table 2, extension plates 17 are fixedly connected to the outside of the front side of the fixing plate 16, a motor 19 is arranged outside the left extension plate 17, a rotating rod 20 is fixedly connected to the output end of the motor 19, the rotating rod 20 is rotatably connected inside the two extension plates 17, gears 21 are fixedly connected to both sides of the outside of the rotating rod 20, rack plates 22 are arranged outside the front side of the fixing plate 16, the two rack plates 22 are engaged with the two gears 21, a top plate 25 is fixedly connected to the upper parts of the two rack plates 22, guide rings 24 are fixedly connected to the outside of the two rack plates 22, ejector rods 26 are fixedly connected to both sides of the upper part of the top plate 25, the tops of the two ejector rods 26 penetrate through the die table 2 and the inside of the lower die 28 and are fixedly connected to an ejector plate 27, telescopic rods 6 are fixedly connected to both sides of the inside of the mounting plate 4, and the tops of the two telescopic rods 6 are fixedly connected to both sides of the upper part of the cross plate 7. Fixed rods 23 are fixedly connected to both sides of the inside of the fixing plate 16, and the two guide rings 24 are slidably connected to the outside of the two fixed rods 23. An L-shaped plate 18 is fixedly connected to the outside of the left extension plate 17, and the motor 19 is fixedly connected to the upper part of the L-shaped plate 18.

[0027] When forging the half - shaft tube head, the forging raw material is heated to an appropriate temperature, and then placed inside the lower die 28. Then, the hydraulic cylinder 5 is started to drive the cross - plate 7 with a fixed output end to move. The movement of the cross - plate 7 drives the mounting block 8 fixed at the lower part to move. The movement of the mounting block 8 drives the mounting post 9 inserted inside to move. The movement of the mounting post 9 drives the upper die 10 fixed at the lower part to move, so that the upper die 10 and the lower die 28 are in contact, and the forging of the half - shaft tube head can be completed. When demoulding is required, the motor 19 is started, and the motor 19 drives the rotating rod 20 fixed at its output end to rotate. The rotation of the rotating rod 20 drives the gears 21 fixed on both sides of its outside to rotate synchronously. The rotation of the gears 21 further drives the two rack plates 22 meshed with its outside to move upward synchronously. As the two rack plates 22 move upward, they drive the top plate 25 fixed at the upper part to move upward synchronously. The movement of the top plate 25 further pulls the ejector rods 26 fixed on both sides of its upper part to move synchronously. When the two ejector rods 26 move upward, they push the demoulding plate 27 fixed at the top to move together. The movement of the demoulding plate 27 ejects the formed half - shaft tube head from the inside of the lower die 28, thus realizing the automatic demoulding of the die of the forged half - shaft tube head. Different from the traditional demoulding method of using a hammer or other tools to manually knock the die to separate the casting from the die, this method can avoid problems such as damage, deformation or residual knocking marks on the die surface, thereby improving the product quality.

[0028] Referring to Figure 4 and Figure 5 For the replacement component 12, it includes a slider 1201. The slider 1201 is slidably connected inside the installation cavity 11. A plug rod 1204 is fixedly connected to the left side of the outside of the slider 1201. A moving rod 1202 is fixedly connected to the right side of the outside of the slider 1201. A grip 1203 is fixedly connected to the outside of the moving rod 1202. A spring 1205 is sleeved on the outside of the moving rod 1202. A jack 15 is opened inside the mounting post 9, and the plug rod 1204 is inserted into the jack 15. A first through - hole 13 is opened on the right side of the outside of the mounting block 8, and the moving rod 1202 is slidably connected inside the first through - hole 13. A second through - hole 14 is opened on the left side inside the installation cavity 11, and the plug rod 1204 is slidably connected inside the second through - hole 14.

[0029] When it is necessary to replace the upper mold 10, first move the grip 1203. The movement of the grip 1203 drives the externally fixed moving rod 1202 to move together. The movement of the moving rod 1202 further drives the externally fixed slider 1201 to slide inside the installation cavity 11. When the slider 1201 moves, it simultaneously drives the insertion rod 1204 fixed to its left side to move. During the process of the slider 1201 moving and driving the insertion rod 1204 to move, the insertion rod 1204 squeezes the spring 1205 sleeved outside the moving rod 1202, causing the spring 1205 to deform under force and store elastic potential energy. When the insertion rod 1204 completely disengages from the inside of the jack 15, the mounting post 9 and the upper mold 10 can be removed from the inside of the mounting block 8. This process simplifies the operation of mold replacement, enabling the operator to easily and safely remove the old or worn mold. When installing a new upper mold 10, first insert the mounting post 9 into the inside of the mounting block 8. Then, release the grip 1203. Under the reaction force of the spring 1205, the insertion rod 1204 will automatically spring back and insert into the inside of the jack 15. In this way, the new upper mold 10 is firmly fixed inside the mounting block 8, ensuring that it will not loosen or shift during subsequent operations, realizing the convenience of replacing the worn upper mold 10 and preventing product size deviation and quality decline caused by mold wear.

[0030] Working principle: When demoulding is required, start the motor 19. The motor 19 drives the rotating rod 20 fixed to the output end to rotate. The rotation of the rotating rod 20 drives the gears 21 fixed on both outer sides to rotate. The rotation of the two gears 21 drives the two rack plates 22 engaged with the outside to move upward synchronously. The upward movement of the two rack plates 22 drives the top plate 25 fixed to the upper part to move. The movement of the top plate 25 drives the ejector rods 26 fixed on both upper sides to move synchronously. The movement of the two ejector rods 26 drives the demoulding plate 27 fixed to the top to move. By moving the demoulding plate 27, the formed half shaft tube head mould can be ejected from the inside of the lower mould 28, realizing automatic demoulding of the forged half shaft tube head mould. Different from the traditional demoulding method of using a hammer or other tools to manually strike the mould to separate the casting from the mould, this method can avoid problems such as damage, deformation or residual knocking marks on the mould surface, thus improving the product quality. Then, when the upper mould 10 needs to be replaced, move the grip 1203. The movement of the grip 1203 drives the moving rod 1202 fixed to the outside to move. The movement of the moving rod 1202 drives the slider 1201 fixed to the outside to move inside the installation cavity 11. When the slider 1201 moves, it drives the insertion rod 1204 fixed to the left outside to move. When the slider 1201 drives the insertion rod 1204 to move, it squeezes the spring 1205 sleeved outside the moving rod 1202, causing the spring 1205 to deform under force. Then, when the insertion rod 1204 disengages from the inside of the jack 15, the mounting post 9 and the upper mould 10 can be taken out from the inside of the mounting block 8. During installation, insert the mounting post 9 into the inside of the mounting block 8, and then release the grip 1203. Under the reaction force of the spring 1205, insert the insertion rod 1204 into the inside of the jack 15, realizing convenient replacement of the worn upper mould 10 and preventing product size deviation and quality decline caused by mould wear.

[0031] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
