Description

Technical Field

[0001] The present application relates to the field of die technology, and in particular to a forging die. Background Art

[0002] Forgings are objects that are formed into the required shape or suitable compression force by plastic deformation under pressure. When forging, the blank is usually loaded into the mold first, and then pressure is applied to the blank in the mold to deform the metal along the mold cavity. The forging is taken out after the blank fills the mold.

[0003] In the related art, a Chinese patent document with publication number CN219292646U discloses a forging die, including a die body, the die body including a first forging cavity section and a second forging cavity section connected to each other, the radial dimension of the first forging cavity section is larger than the radial dimension of the second forging cavity section, and the axial dimension of the first forging cavity section is smaller than the axial dimension of the second forging cavity section. After the forging is formed, the die body is clamped by an external tool clamping arm to flip it so that the side with the first forging cavity section faces downward, and then a die pad is placed on the material removal bottom die; the die body is moved by the clamping arm and impacted on the die pad, so that the formed forging is taken out by the vibration formed by the impact force.

[0004] With respect to the above-mentioned related technologies, since the blank is strongly extruded and formed in the die body, the formed forging will fill the inner cavity of the die body tightly, so that when the die body turns over and impacts the die pad, the formed forging is not easy to fall off. Utility Model Content

[0005] In order to facilitate the removal of forgings in a die body, the present application provides a forging die.

[0006] A forging die provided in this application adopts the following technical solution:

[0008] By adopting the above technical solution, the mold body is clamped by an external tool clamping arm and flipped 180° so that the feed port of the mold body is facing downward. At this time, the push block is located above the forging. The push block is adjusted to slide in the direction close to the inner cavity of the mold body by adjusting the adjustment component, so that the push block pushes the formed forging, which helps to fall off the forging and facilitates the removal of the forging.

[0010] By adopting the above technical solution, when the mold body is moved and impacts the mold pad, the impact rod and the mold pad are abutted and impacted, causing the impact rod to slide toward the direction close to the base, and the push block is driven by the transmission member to slide toward the direction close to the inner cavity of the mold body. The push block pushes the formed forging, which helps to fall off the forging and facilitates the removal of the forging.

[0014] By adopting the above technical solution, the base and the mold body are relatively fixed by the locking member, so that the base and the mold are installed, which makes it easy to take out the forging formed in the mold body.

[0015] Preferably, the locking member comprises a locking nut threadedly sleeved on the mounting rod, and the locking nut is used to abut against a side of the mold body away from the base.

[0016] By adopting the above technical solution, the locking nut is rotated to make the locking nut and the mounting rod screwed or disengaged, so that the base and the mold body can be disassembled and assembled according to needs.

[0017] Preferably, a limiting ring is sleeved on the impact rod, and a limiting groove which is slidably matched with the limiting ring is opened on the inner wall of the through hole.

[0018] Preferably, the limiting member comprises a limiting rod arranged on a side of the push block away from the mold body, and when the limiting rod abuts against the base, the push block fits against the lower end edge of the inner cavity of the mold body.

[0019] By adopting the above technical solution, the push block can be restricted from sliding in a direction away from the die body through the abutment between the limiting rod and the base, thereby reducing the influence on the forging forming.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-2 This application is described in further detail.

[0028] The present application embodiment discloses a forging die. Figure 1 and Figure 2The forging die includes a die body 1, and the internal structure of the die body 1 is the same as the structure in the related art; a base 2 is arranged below the die body 1, and a mounting groove 14 is provided on a side of the base 2 close to the die body 1, and a push block 3 is slidably arranged in the mounting groove 14 along the vertical direction. The cross section of the push block 3 is circular, and the push block 3 is used to fit with the lower end edge of the inner cavity of the die body 1, and an adjustment component for adjusting the push block 3 to slide toward the direction close to the inner cavity of the die body 1 is arranged in the mounting groove 14, and a limiter for limiting the push block 3 from sliding toward the direction away from the inner cavity of the die body 1 is arranged on the push block 3.

[0029] When forging is being processed, the push block 3 is limited by the limiter to slide in the direction away from the inner cavity of the die body 1, so that the forging can be formed on the push block 3. When the forging needs to be taken out of the die body 1, the die body 1 is clamped by the external tool clamping arm and turned 180°, so that the feed port of the die body 1 is facing downward, and the push block 3 is located above the forging. Then, the push block 3 is adjusted by the adjustment component to slide in the direction close to the inner cavity of the die body 1, so that the push block 3 pushes the formed forging, which helps to make the forging fall off, providing convenience for taking out the forging.

[0030] Reference Figure 2 Two mounting rods 6 are symmetrically fixed on opposite sides of the base 2. The mounting rods 6 extend in a direction close to the mold body 1. The length direction of the mounting rods 6 is parallel to the sliding direction of the push block 3. The length of the mounting rods 6 is greater than the length of the mold body 1. A through hole 7 for the mounting rods 6 to slide through is opened on the mold body 1. A locking member for fixing the base 2 and the mold body 1 relative to each other is provided on the mounting rods 6.

[0031] Reference Figure 2 A threaded section 15 is provided on the outer wall of the end of the mounting rod 6 away from the base 2, and the locking member includes a locking nut 8 threadedly sleeved on the mounting rod 6, the locking nut 8 is threadedly matched with the threaded section 15, and the locking nut 8 is used to abut against a side of the mold body 1 away from the base 2.

[0032] When forging is being processed, the locking nut 8 is rotated to disengage the locking nut 8 from the mounting rod 6, and then the mold body 1 is moved in a direction away from the base 2 to disengage the through hole 7 on the mold body 1 from the mounting rod 6, thereby achieving the disengagement of the base 2 from the mold body 1, facilitating the use of the mold body 1 and helping to reduce the impact on the forging forming process.

[0033] When the forging in the die body 1 needs to be taken out, the through hole 7 on the die body 1 is aligned with the two mounting rods 6 on the base 2, and then the die body 1 is slid toward the direction close to the base 2 until the die body 1 abuts against the base 2, and then the locking nut 8 is screwed onto the mounting rod 6 and abuts against the die body 1 to achieve relative fixation of the die body 1 and the base 2; at this time, the push block 3 is aligned with the forging, and then the die body 1 is clamped by the clamping arm and turned 180°, so that the feed port of the die body 1 is downward, which can provide convenience for the removal of the forging.

[0034] Reference Figure 2 A plurality of fixing rods 12 are fixed to the bottom wall of the mounting groove 14, and the fixing rods 12 are located below the push block 3. The length direction of the fixing rods 12 is parallel to the sliding direction of the push block 3. The limiting member includes a limiting rod 11 fixed to the side of the push block 3 away from the inner cavity of the mold body 1. The limiting rod 11 corresponds to the fixing rod 12 one by one. The limiting rod 11 is slidably sleeved on the corresponding fixing rod 12, and the sliding of the push block 3 is guided by the sliding cooperation between the limiting rod 11 and the fixing rod 12; when the limiting rod 11 abuts against the bottom wall of the mounting groove 14, the push block 3 fits against the lower edge of the inner cavity of the mold body 1.

[0035] During the forging process, the push block 3 is limited by the contact between the limiting rod 11 and the bottom wall of the installation groove 14 , so that the push block 3 is not easily pressed and slides in a direction away from the die body 1 .

[0036] Reference Figure 2 A spring 13 is provided on the movable sleeve of the limit rod 11, and the extension direction of the spring 13 is parallel to the sliding direction of the push block 3. One end of the spring 13 is fixed to the side of the push block 3 away from the mold body 1, and the other end is fixed to the bottom wall of the mounting groove 14. The setting of the spring 13 helps to keep the push block 3 in the initial position and is not prone to unnecessary sliding.

[0037] Reference Figure 2 In order to facilitate the adjustment of the push block 3 to slide in the direction close to the inner cavity of the mold body 1, the adjustment assembly includes an impact rod 4 and a transmission member 5. The impact rod 4 is slidably inserted into the mounting rod 6. The sliding direction of the impact rod 4 is parallel to the sliding direction of the push block 3. A limit ring 9 is fixedly sleeved on the impact rod 4. The limit ring 9 is located in the mounting rod 6. The inner wall of the through hole 7 is provided with a limit groove 10 that is slidably matched with the limit ring 9. The length of the limit groove 10 is 10mm-20mm. The sliding match between the limit ring 9 and the limit groove 10 helps to limit the sliding distance of the impact rod 4 and prevents the impact rod 4 from falling out of the mounting rod 6.

[0038] Reference Figure 2The transmission member 5 is arranged in the installation groove 14. The transmission member 5 is used to drive the push block 3 to slide in the direction close to the inner cavity of the mold body 1 when the impact rod 4 slides in the direction close to the base 2. The transmission member 5 includes a first rack 51, a second rack 52 and a gear 53. The first rack 51 is fixed to one end of the impact rod 4 close to the base 2, and the first rack 51 slides in the installation groove 14; the second rack 52 is fixed on the bottom wall of the push block 3, the second rack 52 corresponds to the first rack 51 one by one, and the length directions of the first rack 51 and the second rack 52 are parallel to the sliding direction of the push block 3. The gear 53 corresponds to the first rack 51 one by one, and the gear 53 is located between the corresponding first rack 51 and the second rack 52. The gear 53 is rotatably arranged in the installation groove 14, and the rotation axis of the gear 53 is perpendicular to the sliding direction of the push block 3. The first rack 51 is meshed with the corresponding gear 53, and the second rack 52 is meshed with the corresponding gear 53.

[0039] When the forging needs to be taken out of the die body 1, the die body 1 is clamped by the clamping arm and turned 180° so that the feed port of the die body 1 is downward, and then the die body 1 is moved and impacted onto the die pad, so that the impact rod 4 extending from the mounting rod 6 impacts the die pad, and the impact force drives the impact rod 4 to slide toward the base 2, and the first rack 51 drives the corresponding gear 53 to rotate, and the gear 53 drives the corresponding second rack 52 to slide toward the die body 1, thereby driving the push block 3 to abut the forging in the die body 1, which helps the push block 3 to push the forging out of the die body 1. Under the action of the impact force and the abutting force, the forging can be smoothly moved out of the die body 1.

[0040] The implementation principle of the embodiment of the present application is: when forging is being processed, the locking nut 8 is rotated to disengage the locking nut 8 from the mounting rod 6, and then the mold body 1 is moved in a direction away from the base 2 to disengage the through hole 7 on the mold body 1 from the mounting rod 6, thereby achieving the disengagement of the base 2 from the mold body 1, facilitating the use of the mold body 1 and helping to reduce the impact on the forging forming process.

[0041] When the forging in the mold body 1 needs to be taken out, the through hole 7 on the mold body 1 is aligned with the two mounting rods 6 on the base 2, and the mold body 1 is slid in the direction close to the base 2 until the mold body 1 abuts against the base 2, and then the locking nut 8 is screwed onto the mounting rod 6 and abuts against the mold body 1 to achieve relative fixation of the mold body 1 and the base 2, and then the mold body 1 is clamped by the clamping arm and turned 180° so that the feed port of the mold body 1 is downward, and then the mold body 1 is moved and impacted onto the mold pad, so that the impact rod 4 extending out of the mounting rod 6 impacts the mold pad, and the impact force drives the impact rod 4 to slide in the direction close to the base 2, and the first rack 51 drives the corresponding gear 53 to rotate, and the gear 53 drives the corresponding second rack 52 to slide in the direction close to the mold body 1, thereby driving the push block 3 to abut against the forging in the mold body 1, and the forging can be smoothly moved out of the mold body 1 under the action of the impact force and the abutting force, thereby providing convenience for the removal of the forging.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
