The sleeve bears the impact and pressure experienced by the inner die core during forging.

Description

Technical Field

[0001] This utility model relates to the field of forging die technology, specifically a precision forging die for metal parts. Background Technology

[0002] Forging dies are molds used in the forging process. Under the action of external force, the raw material undergoes plastic deformation within the forging die, thereby obtaining parts of the desired shape and size. Forging dies can be classified according to the forging temperature into hot forging dies, warm forging dies, and cold forging dies. Hot forging dies can also be classified according to the equipment used, such as hammer forging dies, screw press forging dies, mechanical press forging dies, flat forging dies, and hydraulic press forging dies.

[0003] After prolonged use, forging dies experience increased wear due to the impact and pressure they withstand, leading to a decrease in the precision of the forged metal parts and increased difficulty in post-processing. Utility Model Content

The inner die core groove is formed on the inner side of the forging die body, and the inner die core is installed in the inner die core groove. A cavity is formed on the inner side of the inner die core. The sleeve is fitted on the outer side of the forging die body, and the height of the sleeve is equal to the height of the forging die body. The forging die body is composed of two main components.

[0006] Preferably, a limiting ring is provided on the outer surface of the inner mold core, and a limiting groove that cooperates with the limiting ring is provided on the inner side of the forging die body.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] Please see Figure 1-3 In this embodiment of the present invention, a precision forging die for metal parts includes a sleeve 1, a forging die body 2, and an inner die core 3. An inner die core groove 5 is formed on the inner side of the forging die body 2, and the inner die core 3 is installed in the inner die core groove 5. A cavity 4 is formed on the inner side of the inner die core 3. The sleeve 1 is fitted onto the outer side of the forging die body 2, and the height of the sleeve 1 is equal to the height of the forging die body 2. The forging die body 2 is composed of two main components 14. The cavity 4 on the inner side of the inner die core 3 is used for forging and shaping the metal parts. The forging die body 2 is used to support the inner die core 3 and to hold the inner die core within the forging die. The impact and pressure experienced by the die core 3 during forging are evenly transmitted to the sleeve 1. The forging die body 2 is composed of two main components 14, which facilitates the removal of the inner die core 3 from the inside of the forging die body 2 and makes it easier to replace the inner die core 3 after excessive wear, thereby ensuring the dimensional accuracy of the forged metal parts. The sleeve 1 is used to bear the impact and pressure experienced by the inner die core 3 during forging. At the same time, the sleeve 1 also serves to combine the two main components 14 together to form the forging die body 2. The structure of the sleeve 1 is relatively simple, and the replacement cost is also lower when the sleeve 1 cracks.

[0018] A limiting ring 7 is provided on the outer side of the inner mold core 3, and a limiting groove 6 that cooperates with the limiting ring 7 is provided on the inner side of the forging die body 2. The cooperation between the limiting ring 7 and the limiting groove 6 prevents the inner mold core 3 from sliding out of the interior of the forging die body 2.

[0019] The bottom of the inner mold core 3 is provided with an exhaust hole 10 that communicates with the cavity 4. The exhaust hole 10 is used to discharge the gas inside the cavity 4. The bottom of the forging die body 2 is provided with a metal ejection hole 11 that cooperates with the exhaust hole 10. The metal ejection hole 11 can cooperate with the exhaust hole 10 to discharge gas. At the same time, the metal ejection hole 11 is also used to cooperate with ejector pins and similar mechanisms to separate the formed metal parts from the inner mold core 3.

[0020] The lower outer side of the forging die body 2 is provided with a step seat 8. The step seat 8 and the forging die body 2 are an integral structure. The lower inner side of the sleeve 1 is provided with a step groove 13 that cooperates with the step seat 8. The cooperation between the step groove 13 and the step seat 8 makes the combination and positioning of the forging die body 2 and the sleeve 1 simpler.

[0021] A combination shaft 9 is fixed on one side of the lower part of the side plane of the main body component 14, and a combination hole 12 is opened on the other side of the lower part of the side plane of the main body component 14.

[0022] The working principle of this utility model is as follows: This utility model consists of three parts: a sleeve 1, a forging die body 2, and an inner die core 3. The cavity 4 inside the inner die core 3 is used for forging the metal part. The forging die body 2 is used to support the inner die core 3 and evenly transmit the impact force and pressure received by the inner die core 3 during forging to the sleeve 1. The forging die body 2 is composed of two main components 14, which facilitates the removal of the inner die core 3 from the inside of the forging die body 2 and makes it easier to replace the inner die core 3 after excessive wear, thereby ensuring the dimensional accuracy of the forged metal part. The sleeve 1 is used to bear the impact force and pressure received by the inner die core 3 during forging. At the same time, the sleeve 1 also serves to combine the two main components 14 together to form the forging die body 2. The structure of the sleeve 1 is relatively simple, and the replacement cost is also lower when the sleeve 1 cracks.
