Description

Technical Field

[0001] This utility model relates to the field of mold and tooling technology, and in particular to a mold and tooling for forging. Background Technology

[0002] In the forging process, the forming process is carried out by hammer forging. The hammer forging die consists of an upper die (hammer head), a lower die (anvil) and auxiliary components. The material is mostly impact-resistant 5CrNiMo steel. During hammer forging, the oxide scale on the surface of the billet falls off at high temperature, and iron oxide is generated in real time. Manual cleaning is cumbersome and increases cleaning costs. Therefore, we propose a mold tooling for forging to solve the existing problems. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a mold tooling for forging.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a forging mold tooling, comprising a hydraulic rod, a stroke plate, a support base, and a rotating wheel. A fixed mold is provided at the upper end of the support base, a hydraulic rod is provided above the support base, a stroke plate is provided at the lower end of the hydraulic rod, a punch is provided at the lower end of the stroke plate, an annular side ring is sleeved on the outer wall of the fixed mold, an annular flow-guiding metal sheet is provided above the support base located on one side below the side ring and whose upper surface height gradually decreases from the center to the outside, a spring is provided between the annular flow-guiding metal sheet and the support base, and a pressure ring connected to the side ring is attached to the upper end of the annular flow-guiding metal sheet.

[0005] Preferably, the support base is fitted with a ring-shaped side frame with an upper opening corresponding to the edge of the ring-shaped flow-guiding metal sheet. The side frame collects the iron oxide that slides out from the ring-shaped flow-guiding metal sheet.

[0006] Preferably, each end of the travel plate has an internal mounting groove, and a rotating shaft is rotatably mounted inside each mounting groove. A rotating wheel is sleeved on the outer wall of the rotating shaft, and four sets of roller grooves corresponding to the rotating wheels are fixed above the support base. When the travel plate moves longitudinally, the rotating wheels rotate inside the roller grooves, providing longitudinal sliding guidance for the longitudinally moving travel plate.

[0007] Preferably, the outer wall of the rotating wheel is rotatably fitted with balls that roll and adhere to the inner wall of the groove. The balls rotate within the groove, coordinating with the rotation of the rotating wheel itself, ensuring the balls roll and adhere to the inner wall of the groove, thus reducing friction and resistance during passage.

[0008] Preferably, a compression spring is provided on the inner wall of the mounting groove, and a retaining sleeve is provided at one end of the compression spring. A graphite block is provided inside the retaining sleeve, and one end of the graphite block is attached to the outer wall of the ball. The elastically supported retaining sleeve rubs against the ball through the graphite block, and the resulting graphite dust adheres to the ball, thus lubricating it.

[0009] Preferably, the compression spring is provided with a slidably inserted positioning cylinder and a positioning rod inside, one end of the positioning cylinder is connected to the inner wall of the mounting groove, and one end of the positioning rod is connected to the retaining sleeve.

[0010] Preferably, a limit rod is provided at the upper end of the positioning rod, and a stop block corresponding to the limit rod is provided on the inner wall of the mounting groove. After the graphite block wears down, the elastic support force of the compression spring keeps it in contact with the outer wall of the ball bearing. The limit rod moves with the positioning rod, limiting the upper end of the graphite block and preventing it from detaching from the mounting groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model uses a hydraulic rod to drive a die to stamp and forge a heated metal part in a fixed die. During this process, the iron oxide generated on the outer wall of the heated metal part detaches from the metal part under the impact force. An annular guide metal sheet with a sloping surface is set on the outside of the fixed die. When the die impacts the metal part, the vibration force generated causes the annular guide metal sheet to shake. The iron oxide slides outward during the shaking process and is automatically collected by the collection structure on the outside of the support seat. This realizes the automatic collection of iron oxide, avoids manual cleaning, improves the working environment, and reduces the intensity of cleaning work. Attached Figure Description

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.

[0020] like Figures 1-5 As shown, the present invention proposes a forging mold tooling, including a hydraulic rod 1, a stroke plate 2, a support base 9 and a rotating wheel 14. A fixed mold 6 is provided at the upper end of the support base 9, the hydraulic rod 1 is provided above the support base 9, the stroke plate 2 is provided at the lower end of the hydraulic rod 1, and a punch 8 is provided at the lower end of the stroke plate 2. A side ring 11 in the shape of an annular ring is sleeved on the outer wall of the fixed mold 6. An annular flow guiding metal sheet 7 is provided above the support base 9, located on one side below the side ring 11, and the height of the upper surface gradually decreases from the center to the outside. A spring 10 is provided between the annular flow guiding metal sheet 7 and the support base 9. A pressure ring 12 connected to the side ring 11 is attached to the upper end of the annular flow guiding metal sheet 7.

[0021] A side frame 5, which is annular and has an opening at the top corresponding to the side of the annular flow guiding metal sheet 7, is sleeved on the outside of the support base 9.

[0022] The travel plate 2 has mounting grooves 3 inside both ends, and a rotating shaft 13 is rotatably installed inside the mounting groove 3. A rotating wheel 14 is sleeved on the outer wall of the rotating shaft 13. Four sets of roller grooves 4 corresponding to the rotating wheel 14 are fixed above the support base 9.

[0023] The outer wall of the rotating wheel 14 is rotatably mounted with ball bearings 15 that roll and fit against the inner wall of the groove 4;

[0024] A compression spring 17 is provided on the inner wall of the mounting groove 3. A retainer 22 is provided at one end of the compression spring 17. A graphite block 18 is provided inside the retainer 22. One end of the graphite block 18 is attached to the outer wall of the ball 15.

[0025] The compression spring 17 is provided with a slidingly inserted positioning cylinder 16 and a positioning rod 21. One end of the positioning cylinder 16 is connected to the inner wall of the mounting groove 3, and one end of the positioning rod 21 is connected to the sleeve 22.

[0026] A limit rod 19 is provided at the upper end of the positioning rod 21, and a stop block 20 corresponding to the limit rod 19 is provided on the inner wall of the mounting groove 3;

[0027] Based on the implementation steps of Example 1: The operator first places the heated metal billet in the center of the fixed mold 6, and drives the stroke plate 2 to press down through the hydraulic rod 1, so that the punch 8 and the fixed mold 6 are closed to form a forging cavity. During the forging process, the iron oxide scale generated by the high temperature oxidation on the surface of the billet falls off under the impact force. At this time, the annular guide metal sheet 7 is supported by the spring 10 to form a flexible floating platform. Its upper surface has a sloping structure with a high center and a low outer side. With the vibration energy generated by forging, the fallen iron oxide automatically slides along the sloping surface to the edge. When the iron oxide contacts the side frame 5, its annular opening design achieves precise collection, completely replacing the traditional manual scraping and cleaning process.

[0028] During equipment operation, the stroke plate 2 achieves precise longitudinal movement through the guide mechanism formed by the rotating wheel 14 and the groove 4. The ball 15 on the outer wall of the rotating shaft 13 forms a rolling friction pair with the inner wall of the groove 4. The compression spring 17 pushes the sleeve 22 to keep the graphite block 18 always in contact with the surface of the ball 15. During the friction process, graphite particles are continuously released to form a lubricating film, which reduces the coefficient of friction. When the graphite block 18 wears, the positioning rod 21 drives the sleeve 22 to automatically compensate for the displacement under the action of the compression spring 17. The limit rod 19 and the stop block 20 cooperate to prevent the graphite block 18 from falling out, ensuring the long-term stable operation of the lubrication system.

[0029] During forging, the annular guide metal sheet 7 forms a guide channel with the pressure ring 12 and the side ring 11. When the die 8 impacts and generates vibration waves, the metal sheet undergoes slight elastic deformation, and the spring 10 compensates for its excessive deformation. Its natural frequency resonates with the forging frequency, accelerating the iron oxide peeling process. The spring 10 assembly uses three sets of circumferentially distributed springs 10. The elastic support force of the spring 10 ensures the sheet resets, and the nonlinear stiffness characteristics attenuate high-frequency vibrations, preventing the impact energy from being transmitted to the frame, allowing the iron oxide to be automatically discharged, reducing the amount of iron oxide accumulated around it, and significantly improving the working environment.
