Description

Technical Field

[0001] This application relates to the field of bucket tooth forging technology, specifically to a hydraulic clamping device for the forging process of bucket teeth. Background Technology

[0002] Excavator bucket teeth are important consumable parts on excavators. They are combined bucket teeth consisting of a tooth base and a tooth tip, which are connected by a pin. In the production process of excavator bucket teeth, heated raw materials are poured into the mold cavity, and then punched downwards to form the shape of bucket teeth with the mold cavity. After cooling, the forging is completed. In order to avoid forging defects and accidents to the equipment, the mold must be reliably closed during forging. Therefore, hydraulic mold locking equipment is required.

[0003] When existing hydraulic clamping equipment is in use, if the clamping structure malfunctions, the mold may slip or shake. However, because the displacement distance of the mold may be small, it is not easy for personnel to notice, thus causing certain safety hazards.

[0004] To address the aforementioned technical problems, patent CN214920401U discloses a hydraulic mold-closing device for a die-casting machine, comprising a first mold, a second mold, and a die-casting host. The first mold is fixedly connected to one side of the die-casting host, and a second fixed edge is fixedly connected to one side of the first mold. Push blocks are uniformly fixedly connected to one side of the second fixed edge. A buffer structure is provided inside the first mold, comprising an inner membrane, a groove, a buffer spring, and a cavity. The cavity is located inside the first mold, and grooves are uniformly arranged on the inner wall of the cavity. This invention also features a hydraulic cylinder fixedly connected to the other side of the die-casting host. Activation of the hydraulic cylinder can open or close the second mold. During the movement of the second mold, a first connecting rod and a second connecting rod support the second mold, making its movement more stable and preventing tilting, thus ensuring more stable mold closing.

[0005] However, the above technical solution has the following drawbacks:

[0006] (1) When the mold locking structure fails, the mold may slip or shake. However, because the distance the mold may move is small, it is not easy for personnel to notice, which may cause certain safety hazards. Summary of the Invention

[0014] In a further preferred embodiment, a contact rod is fixedly connected to the left end of the rack, a threaded rod is rotatably provided on the upper left side of the front end face of the support plate, an adjusting plate is threadedly connected to the threaded rod, a slide rod is slidably connected to the lower right end of the adjusting plate, the rear end of the slide rod is fixedly connected to the support plate, and a buzzer alarm is provided on the rear side of the left end face of the adjusting plate.

[0015] In a further preferred embodiment, an L-shaped rod is fixedly connected to the rear side of the upper surface of the adjustment plate, a third hydraulic cylinder is fixedly connected to the right end of the L-shaped rod, and a brush plate is fixedly connected to the piston end of the third hydraulic cylinder.

[0016] In a further preferred embodiment, a flue gas purifier is provided in the middle of the left end face of the frame. A flexible hose is connected to the upper end of the flue gas purifier.

[0021] (2) During the forging process of the billet, fumes will be generated. The fumes can be drawn in by starting the fumes purifier, using the exhaust fan, fume hood, and hose. At the same time, the second gear will reciprocate under the action of the first motor. When the second gear reciprocates, the arc block will slide clockwise and counterclockwise. The maximum distance that the arc block moves in each direction is just to the rightmost side of the gear ring, which expands the adsorption range of the fume hood. Thus, the fumes can be evenly adsorbed into the fumes purifier for purification, which is more environmentally friendly. Attached Figure Description

[0036] The existing technology has the following drawbacks:

[0037] (1) When existing hydraulic mold clamping equipment is in use, the mold may slip or shake when the mold clamping structure fails. However, because the distance the mold may move is small, it is not easy for personnel to notice, thus causing certain safety hazards.

[0038] As an improvement, such as Figures 1-9 As shown, the preferred embodiment of this application is as follows:

[0039] A hydraulic clamping device for forging bucket teeth includes a forging table 1, a frame 3 fixedly connected to the upper end of the forging table 1, a first hydraulic cylinder 4 fixedly connected to the upper end of the frame 3, a punch 5 fixedly connected to the piston end of the first hydraulic cylinder 4, a first mold 6 fixedly connected to the right side of the upper end of the forging table 1, guide rods 44 fixedly connected to both the front and rear sides of the upper end of the forging table 1, a second mold 7 embedded in and slidably connected to the guide rods 44, and a clamping mechanism for clamping the second mold 7 and the first mold 6 is provided on the upper end of the forging table 1.

[0040] The mold locking mechanism includes a limiting rod 17 fixedly connected to the front and rear sides of the first mold 6. The limiting rod 17 is slidably connected to an insert block 18. The insert block 18 is inserted into a groove block 19. The left end of the groove block 19 is fixedly connected to a second connecting block 21. One end of the second connecting block 21 is fixedly connected to the second mold 7. The groove block 19 is inserted into and slidably connected to a first connecting block 20. One end of the first connecting block 20 is fixedly connected to the first mold 6.

[0041] like Figures 1-4 , Figure 6 and Figure 7 As shown, in this embodiment, a second hydraulic cylinder 14 is fixedly connected to the right side of the upper end face of the forging table 1, and a concave rod 16 is fixedly connected to the piston end of the second hydraulic cylinder 14. Both ends of the left side of the concave rod 16 are fixedly connected to the insert block 18.

[0042] A mounting plate 13 is fixedly connected to the right side of the upper end face of the forging table 1. A fourth hydraulic cylinder 28 is fixedly connected to both the front and rear sides of the left end face of the mounting plate 13. The piston end of the fourth hydraulic cylinder 28 is fixedly connected to the second mold 7.

[0043] A support plate 10 is fixedly connected to the middle of the front side of the upper end of the forging table 1. A housing 11 is fixedly connected to the upper side of the front end of the support plate 10. A filter screen 12 is provided at the right end of the housing 11.

[0044] An eccentric block 39 and a first gear 29 are rotatably connected to the upper end of the support plate 10 via a rotating shaft. A rack 15 is fixedly connected to the front end of the second connecting block 21. The rack 15 meshes with the first gear 29. A fixing block 43 is fixedly connected to the upper side of the front end face of the support plate 10. A reciprocating rod 41 is slidably connected to the fixing block 43. A pressing plate 40 is fixedly connected to the upper end of the reciprocating rod 41. A second striking block 45 is fixedly connected to the lower end of the reciprocating rod 41. A spring damper 42 is fixedly connected to the rear side of the upper end face of the second striking block 45. The piston end of the spring damper 42 is fixedly connected to the fixing block 43. A first striking block 9 is fixedly connected to the upper side of the front end face of the support plate 10.

[0045] A contact rod 38 is fixedly connected to the left end of the rack 15. A threaded rod 27 is rotatably provided on the upper left side of the front end face of the support plate 10. An adjusting plate 22 is threadedly connected to the threaded rod 27. A sliding rod 26 is slidably connected to the lower right side of the adjusting plate 22. The rear end of the sliding rod 26 is fixedly connected to the support plate 10. A buzzer alarm 23 is provided on the rear side of the left end face of the adjusting plate 22.

[0046] An L-shaped rod 24 is fixedly connected to the rear side of the upper end face of the adjusting plate 22. A third hydraulic cylinder 25 is fixedly connected to the right end of the L-shaped rod 24. A brush plate 36 is fixedly connected to the piston end of the third hydraulic cylinder 25.

[0047] Specifically, when the billet needs to be forged into bucket teeth, the fourth hydraulic cylinder 28 is first activated to move the second mold 7 from left to right, so that the second mold 7 fits against the first mold 6, forming a cavity between them for the billet to be formed. When the second mold 7 fits against the first mold 6, the grooved block 19 passes through the first connecting block 20. Then, the second hydraulic cylinder 14 is activated to raise the concave rod 16, causing the insert block 18 to slide upwards on the limiting rod 17, inserting the insert block 18 into the grooved block 19. This achieves a secure connection between the second mold 7 and the first mold 6, completing the mold-locking effect. To prevent the second mold 7 from separating from the first mold 6 due to unforeseen circumstances during forging, and to prevent personnel from failing to detect it in time, a further mechanism can be used after mold locking. Then, manually rotate the threaded rod 27 to move the adjusting plate 22 backward, so that the switch 37 is aligned with the contact rod 38. When the second mold 7 moves to the left unexpectedly, the contact rod 38 will also move to the left and then contact the switch 37. At this time, the buzzer alarm 23 will be activated to remind personnel that the first mold 6 has separated from the second mold 7. Furthermore, when the second mold 7 wobbles from side to side, it will cause the rack 15 to move. The rack 15 will then drive the first gear 29 to rotate, causing the eccentric block 39 to rotate. When the eccentric block 39 rotates, it will contact the extrusion plate 40, causing the extrusion plate 40 to drive the reciprocating rod 41 to slide on the fixed block 43, thus causing the second striking block 45 to move up and down. When the second striking block 45 moves downward... When in motion, it will contact the first striking block 9. At this time, the collision between the first striking block 9 and the second striking block 45 will produce a sound. Simultaneously, under the action of the spring damper 42, the second striking block 45 will reset, realizing cyclical impact. Moreover, the sound can be transmitted through the filter screen 12 to alert personnel that the second mold 7 has shifted. Using this mechanical transmission method, personnel can be alerted when the buzzer alarm 23 malfunctions or when the second mold 7 shakes from side to side. This dual protection method improves overall safety. Furthermore, since there may be slag splashing during the forging process, this slag may splash onto the end faces of the contact rod 38 and the switch 37 that are close to each other. When a lot of slag adheres to the end faces of the two that are close to each other, it may cause... If residue clumps together, it reduces the distance between the contact rod 38 and the switch 37, potentially causing them to touch under normal circumstances. Therefore, the brush plate 36 can be periodically moved downwards by activating the third hydraulic cylinder 25, allowing the brush bristles of the brush plate 36 to contact the adjacent end faces of the contact rod 38 and the switch 37, ensuring both are cleaned and preventing the switch 37 from being accidentally turned on. This effectively locks the first mold 6 and the second mold 7, preventing forging defects and even equipment or workplace accidents. Furthermore, if the equipment used to lock the first mold 6 and the second mold 7 malfunctions, causing the second mold 7 to slip, it can promptly emit an audible warning to nearby personnel, further enhancing safety.

[0048] like Figure 2 As shown, in this embodiment, a flue gas purifier 8 is provided in the middle of the left end face of the frame 3. A flexible hose 34 is connected to the upper end of the flue gas purifier 8. The flexible hose 34 passes through and is fixedly connected to the frame 3. A smoke collection hood 30 is connected to the right end of the flexible hose 34. An arc-shaped block 33 passes through the right end of the flexible hose 34 and is fixedly connected to it. A gear ring 31 is slidably connected to the arc-shaped block 33. The left end of the gear ring 31 is fixedly connected to the frame 3. A first motor 32 is fixedly connected to the upper end face of the arc-shaped block 33. A second gear 35 is fixedly connected to the output end of the first motor 32 through a rotating shaft. The second gear 35 meshes with the gear ring 31.

[0049] A fan is installed at the left end of the flue gas purifier 8 to generate suction force in the hose 34;

[0050] Specifically, during the forging process of the billet, fumes are generated. The fumes can be drawn in by activating the fume purifier 8, using a fan, fume hood 30, and hose 34. At the same time, the second gear 35 reciprocates under the action of the first motor 32. When the second gear 35 reciprocates, the arc block 33 slides clockwise and counterclockwise. The maximum distance that the arc block 33 moves in each direction is exactly to the rightmost side of the gear ring 31, which expands the adsorption range of the fume hood 30. This allows the fumes to be evenly adsorbed into the fume purifier 8 for purification, which is more environmentally friendly.

[0051] The working principle of this application is as follows: When it is necessary to forge the billet into bucket teeth, firstly, the fourth hydraulic cylinder 28 is activated to drive the second mold 7 to move from left to right, so that the second mold 7 fits with the first mold 6, forming a cavity between them that allows the billet to be formed. When the second mold 7 fits with the first mold 6, the groove block 19 passes through the first connecting block 20. Then, the second hydraulic cylinder 14 is activated to drive the concave rod 16 to rise, causing the insert block 18 to slide upwards on the limiting rod 17, inserting the insert block 18 into the groove block 19. This achieves a firm connection between the second mold 7 and the first mold 6, completing the mold-locking effect. Then, the billet is added into the cavity between the second mold 7 and the first mold 6, using the first hydraulic cylinder 28 to further connect the two molds. The pressure cylinder 4 drives the punch 5 to descend, forging the billet. To prevent the second mold 7 from separating from the first mold 6 due to unforeseen circumstances during forging, and to prevent personnel from noticing in time, the threaded rod 27 can be manually rotated after mold locking to move the adjusting plate 22 backward, aligning the switch 37 with the contact rod 38. When the second mold 7 moves to the left unexpectedly, the contact rod 38 will also move to the left and then contact the switch 37. At this time, the buzzer alarm 23 will be activated, emitting a sound to remind personnel that the first mold 6 has separated from the second mold 7. Furthermore, when the second mold 7 wobbles from side to side, it will cause the rack 15 to move, which in turn will drive the first gear... The rotation of wheel 29 causes the eccentric block 39 to rotate. When the eccentric block 39 rotates, it comes into contact with the extrusion plate 40, causing the extrusion plate 40 to drive the reciprocating rod 41 to slide on the fixed block 43. This allows the second striking block 45 to move up and down. When the second striking block 45 moves downward, it comes into contact with the first striking block 9. At this time, the collision between the first striking block 9 and the second striking block 45 produces a sound. Simultaneously, the second striking block 45 is reset by the action of the spring damper 42, achieving cyclic impact. Furthermore, the sound can be transmitted through the filter screen 12 to alert personnel that the second mold 7 has shifted. This mechanical transmission method can be used to alert personnel when the buzzer alarm 23 malfunctions or when the second mold 7 shakes from side to side. The use of a double-protection method improves overall safety. Furthermore, during the forging process, residue may splash, which may land on the end faces of the contact rod 38 and the switch 37 that are close to each other. When a lot of residue adheres to the end faces of the two, the residue may clump together. When the residue clumps together, it is equivalent to reducing the distance between the contact rod 38 and the switch 37, which may cause them to touch under normal circumstances. Therefore, the brush plate 36 can be moved downward by periodically activating the third hydraulic cylinder 25, so that the brush bristles of the brush plate 36 contact the end faces of the contact rod 38 and the switch 37 that are close to each other, so that both are cleaned and the switch 37 is prevented from being accidentally turned on.This mechanism effectively locks the first mold 6 and the second mold 7, preventing forging defects and even equipment and workplace accidents. Furthermore, if the equipment used to lock the first mold 6 and the second mold 7 malfunctions, causing the second mold 7 to slip, it can promptly emit an audible warning to nearby personnel, further enhancing safety. During the forging process of the billet, fumes are generated. These fumes can be drawn in by activating the fume purifier 8, using a fan, fume hood 30, and hose 34. Simultaneously, the second gear 35 reciprocates under the action of the first motor 32. When the second gear 35 reciprocates, the arc-shaped block 33 slides clockwise and counterclockwise. The maximum distance the arc-shaped block 33 moves in each direction is precisely to the rightmost side of the gear ring 31, thus expanding the adsorption range of the fume hood 30. This allows the fumes to be evenly adsorbed and purified by the fume purifier 8, making it more environmentally friendly. After forging is completed, the locking mechanism is reversed to separate the first mold 6 and the second mold 7, allowing the formed bucket teeth to be removed.
