Description

Technical Field

[0001] The utility model relates to the field of forging dies, in particular to an automatic forging die for iron teeth. Background Art

[0002] The iron teeth targeted by this scheme are shaped like rectangular plates, the thickness of which gradually decreases from the middle to the two ends along the long side, and then two symmetrical convex teeth are provided in the middle of the plate. During forging, the two convex teeth are at the top. Since the convex teeth are in the upper die, the die sticking phenomenon cannot be completely avoided with or without a push rod, and manual adjustment is required in a timely manner. In addition, the flash produced is irregular, and a manipulator or robot cannot clamp stably. The manual participation is relatively high, and the corresponding risk factor is also high.

[0003] In view of the above problems existing in the prior art, the present invention designs and manufactures an automatic forging die for iron teeth in combination with many years of design and use experience in related fields to overcome the above defects. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides an automatic iron tooth forging die, which prevents the iron tooth forging from sticking to the die and ensures the grabbing stability of the iron tooth forging.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: an automatic forging die for iron teeth, comprising an upper forging die and a lower forging die, wherein the lower forging die is provided with a lower die cavity, and a flash shaping bin is respectively provided on the end surfaces at both ends of the lower die cavity in the length direction;

[0006] Two V-shaped grooves are respectively arranged on the end surfaces on both sides in the width direction of the lower mold cavity, and the two V-shaped grooves on each side are symmetrically arranged in the length direction of the lower mold cavity, and the two slopes of the V-shaped grooves correspond to the length direction of the lower mold cavity. A long material bin is arranged at the bottom of each V-shaped groove, and the length of the long material bin corresponds to the length direction of the lower mold cavity. A lower ejector pin is arranged at the bottom of each long material bin;

[0007] The forging upper die is provided with an upper die cavity, and two conical platforms are respectively provided on the end surfaces on both sides of the width direction of the upper die cavity, and the two conical platforms on each side are symmetrically arranged in the length direction of the upper die cavity, and the two slopes of the conical platforms correspond to the length direction of the upper die cavity. Two upper ejectors are also provided in the upper die cavity, and the two upper ejectors are arranged on the end surfaces on both sides of the middle of the upper die cavity;

[0008] When the forging upper die and the forging lower die are closed, the conical platform cooperates with the V-shaped groove.

[0009] Preferably, two convex tooth cavities are provided in the middle of the upper mold cavity, and two conical platforms on each side of the upper mold cavity are respectively provided on both sides of the two convex tooth cavities.

[0010] Preferably, the total volume of the four long silos is greater than the total volume of the two convex tooth cavities.

[0011] Preferably, both ends of the flash shaping bin extend to both sides in the width direction of the forging lower die.

[0012] Preferably, the height of the V-shaped groove near one end of the flash forming bin is lower than the upper end surface of the forging lower die.

[0013] Preferably, the length of the V-shaped groove is less than half the length of the lower mold cavity.

[0014] The utility model is beneficial in that:

[0015] During forging and forming, the flash will enter the flash shaping bins at both ends of the lower die cavity. The flash shaping bins make the flash at both ends of the forged product smoother, and the mechanical claws can grasp through the smooth flash positioning bosses at both ends, ensuring the stability of grasping. In addition, the long bins on both sides will also be filled with flash on both sides. When the forging is ejected from the die, the long bins have a certain resistance to the forging. At the same time, the upper ejector of the forging upper die is used to eject the forging to prevent the forging from sticking to the forging upper die, ensuring that the forging can be first in the lower die cavity when demolding.

[0025] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 8 As shown, an automatic forging die for iron teeth includes a forging upper die 1 and a forging lower die 2. The forging lower die 2 is provided with a lower die cavity 21. The end faces of the lower die cavity 21 at both ends in the length direction are respectively provided with a flash shaping bin 22. Both ends of the flash shaping bin 22 extend to both sides in the width direction of the forging lower die 2. Even if more flash flows into the flash shaping bin 22, it will be discharged through both ends of the flash shaping bin 22.

[0027] During forging, the flash will enter the flash shaping bins 22 at both ends of the lower die cavity 21. The setting of the flash shaping bins 22 makes the flash at both ends of the forged product smoother, and the mechanical claw can grasp through the smooth flash positioning bosses at both ends, ensuring the stability of grasping.

[0028] The utility model provides two V-shaped grooves 25 on the end surfaces on both sides of the width direction of the lower mold cavity 21, and the two V-shaped grooves 25 on each side are symmetrically arranged in the length direction of the lower mold cavity 21, and the two slopes of the V-shaped grooves 25 correspond to the length direction of the lower mold cavity 21. A long material bin 23 is provided at the bottom of each V-shaped groove 25, and the length of the long material bin 23 corresponds to the length direction of the lower mold cavity 21. A lower ejector pin 24 is provided at the bottom of each long material bin 23;

[0029] An upper die cavity 11 is provided on the forging upper die 1, two convex tooth cavities 12 are provided in the middle of the upper die cavity 11, two conical platforms 14 are provided on the end surfaces on both sides of the width direction of the upper die cavity 11, the two conical platforms 14 on each side of the upper die cavity 11 are respectively arranged on both sides of the two convex tooth cavities 12, the two conical platforms 14 on each side are symmetrically arranged in the length direction of the upper die cavity 11, the two slopes of the conical platforms 14 correspond to the length direction of the upper die cavity 11, and two upper ejectors 13 are also provided in the upper die cavity 11, and the two upper ejectors 13 are arranged on the end surfaces on both sides of the middle of the upper die cavity 11;

[0030] When the forging upper die 1 and the forging lower die 2 are closed, the conical platform 14 cooperates with the V-shaped groove 25. Since the long material bins 23 on both sides will also be filled with the flash on both sides, the long material bins 23 have a certain resistance to the forging 3 being ejected from the die when the forging 3 is ejected from the die. At the same time, the upper ejector pin 13 of the forging upper die 1 is used to eject the forging 3 to prevent it from sticking to the forging upper die 1, ensuring that the forging 3 can be first in the lower die cavity 21 when demolding.

[0031] The total volume of the four long material bins 23 of the utility model is greater than the total volume of the two convex tooth cavities 12, so that the resistance of the forging 3 to be demoulded from the lower die of the forging 3 is greater than the resistance of the forging 3 to be demoulded from the upper die.

[0032] The height of the V-groove 25 near one end of the flash shaping bin 22 is lower than the upper end surface of the forging lower die 2, so that excess flash material can enter the V-groove 25 or even the long bin 23, avoiding the flash material from being discharged from both ends of the flash shaping bin 22 during forging.

[0033] The length of the V-shaped groove 25 is preferably less than half the length of the lower mold cavity 21, so that each V-shaped groove 25 is independent of each other, thereby increasing the demoulding resistance area.

[0034] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
