[0001] This utility model relates to the field of forging press technology, specifically a direct-drive hot die forging press. Background Technology

[0002] Forging involves heating a cylindrical steel ingot to the required temperature in a furnace and then placing it on the worktable of a forging press for forging. Through forging, the steel ingot is gradually made thinner and longer until it reaches the desired shape.

[0003] The existing hot-film forging press equipment has the main problem of not being able to quickly change the upper and lower dies during use. As a result, the service life of the upper and lower dies is reduced after the upper and lower dies have been forging for a long time, and they are prone to damage, which affects the forging efficiency. Secondly, the existing hot-film forging press equipment also lacks the ability to position the die during use, which makes the die prone to shaking or instability during the forging process, resulting in forging failure or unqualified forging. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a direct-drive hot die forging press, which has the advantages of quick replacement of upper and lower dies and easy positioning of the die, thus solving the problems mentioned in the background art.

[0006] As a preferred technical solution of this utility model: the inner wall of the storage groove is provided with a limiting groove, the outer side of the card block is fixedly installed with a limiting block, and the limiting block is slidably connected to the limiting groove.

[0007] As a preferred technical solution of this utility model: the insertion rod is fixedly installed with the threaded column, and the threaded column is slidably connected with the inner wall of the rotating drum.

[0008] As a preferred technical solution of this utility model: there are two auxiliary pressing blocks and two auxiliary support blocks, and a brake is provided on the side of the crank away from the motor.

[0009] As a preferred technical solution of this utility model: the power output shaft of the motor is fixedly mounted with a flywheel, and the device is externally equipped with a remote control. Both the motor and the brake are electrically connected to the remote control.

[0010] As a preferred technical solution of this utility model: the diameter of the insertion rod is adapted to the diameter of the slot, sleeves are fixedly installed on both sides of the slide rod two, a rotating cylinder is rotatably connected to the inner wall of the sleeve, and a limit ring is fixedly installed on the outer edge of the rotating cylinder.

A rotating ring is fixedly sleeved on the outer edge of the rotating cylinder.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This direct-drive hot die forging press utilizes the cooperation between the locking block and the receiving groove. When it is necessary to replace the upper or lower die, simply press the locking block inward, causing it to compress the spring on the inner wall of the receiving groove, resulting in deformation and contraction. At this time, the locking block slides into the receiving groove. When the locking block is stored in the receiving groove and separates from the positioning block, the sliding rod and the upper die can be removed from the inner wall of the positioning block and the auxiliary lower pressure block, and a new sliding rod and upper die can be replaced. This avoids the upper die affecting the forging efficiency of the die due to prolonged use.

[0013] 2. This direct-drive hot die forging press, through the cooperation of the insert rod and slot, allows the mold to be fixed when placed on top of the lower die. Simply rotate the rotating ring clockwise to make the rotating ring drive the rotating drum to rotate. Utilizing the sleeve between the rotating drum and the transmission belt, the transmission belt drives the other two rotating drums to rotate together. At this time, through the threaded connection between the rotating drum and the threaded column, the insert rod will slide outward, causing the insert rod to separate from the inner wall of the slot. After the mold is placed on top of the lower die, by aligning the slot on the outer edge of the mold with the slot on the outer edge of the lower die, and rotating the rotating ring counterclockwise, the insert rod is reinserted into the inner wall of the slot. This serves to fix and limit the mold, preventing the mold from shaking or becoming unstable during the forging process. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1-7A direct-drive hot die forging press includes a frame 1. A top frame 30 is provided on the top of the frame 1. A motor 3 is fixedly installed on the outer side of the top frame 30. A crank 5 is fixedly installed on the power output shaft of the motor 3. A connecting rod 6 is provided on the outer edge of the crank 5. A movable block 8 is sleeved on the outer wall of the connecting rod 6. A solid block 9 is fixedly installed on the bottom of the movable block 8. A positioning block 10 and an auxiliary pressing block 11 are fixedly installed on the bottom of the solid block 9. A sliding rod 12 is slidably connected to the inner wall of the positioning block 10 and the auxiliary pressing block 11. An upper die 13 is fixedly installed on the bottom of the sliding rod 12. A receiving groove 26 is formed on the outer edge of the positioning block 10 and the outer wall of the sliding rod 12. The receiving groove 26 contains... A spring 27 is provided on the wall, and a locking block 28 is fixedly installed on the extended end of the spring 27. A support leg 2 is fixedly installed at the bottom of the frame 1, and a base frame 14 is fixedly installed at the bottom of the support leg 2. A positioning block 2 15 and an auxiliary support block 16 are fixedly installed on the top of the base frame 14. A sliding rod 2 17 is slidably connected to the inner wall of the positioning block 2 15 and the auxiliary support block 16. A lower mold 18 is fixedly installed on the top of the sliding rod 2 17.

Sleeves 21 are fixedly installed on both sides of the sliding rod 2 17. A rotating cylinder 23 is rotatably connected to the inner wall of the sleeve 21.

[0024] In the above structure, through the cooperation between the locking block 28 and the receiving groove 26, when it is necessary to replace the upper mold 13 or the lower mold 18, simply press the locking block 28 inward, so that the locking block 28 compresses the spring 27 on the inner wall of the receiving groove 26 and deforms and contracts. At this time, the locking block 28 slides into the receiving groove 26. When the locking block 28 is stored in the receiving groove 26 and separated from the positioning block 10, the slide rod 12 and the upper mold 13 can be removed from the inner wall of the positioning block 10 and the auxiliary lower pressing block 11, and then a new slide rod 12 and the upper mold 13 can be replaced, thus avoiding the upper mold 13 from affecting the forging efficiency of the mold 31 due to long-term use.

[0025] In a preferred embodiment: a limiting groove is formed on the inner wall of the storage groove 26, and a limiting block 29 is fixedly installed on the outer side of the locking block 28, and the limiting block 29 is slidably connected to the limiting groove.

[0026] In the above structure, the sliding of the card block 28 can be limited by the setting of the limiting groove and the limiting block 29.

[0027] In a preferred embodiment: the insert rod 20 is fixedly installed with the threaded post 25, and the threaded post 25 is slidably connected to the inner wall of the rotating drum 23.

[0028] In the above structure, the threaded post 25 is provided to prevent the insertion rod 20 from sliding directly out of the inner wall of the rotating drum 23.

[0029] In a preferred embodiment, there are two auxiliary pressing blocks 11 and two auxiliary support blocks 16, and a brake 7 is provided on the side of the crank 5 away from the motor 3.

[0030] In the above structure, the two auxiliary pressing blocks 11 and the auxiliary support block 16 can provide auxiliary support and auxiliary downward pressure for the slide rod 12 and the slide rod 2 17.

[0031] In a preferred embodiment: the power output shaft of the motor 3 is fixedly mounted with a flywheel 4, and the device is externally equipped with a remote control. Both the motor 3 and the brake 7 are electrically connected to the remote control.

[0032] In the above structure, the motor 3 and the brake 7 can be easily controlled by setting the remote control.

[0033] In a preferred embodiment: the diameter of the insertion rod 20 is adapted to the diameter of the slot 19, sleeves 21 are fixedly installed on both sides of the slide rod 27, a rotating cylinder 23 is rotatably connected to the inner wall of the sleeve 21, and a limit ring 22 is fixedly installed on the outer edge of the rotating cylinder 23. There are two sets of rotating cylinders 23, three in each set. A transmission belt 24 is sleeved on the outer edge of each set of rotating cylinders 23. A threaded post 25 is fixedly installed on the outer edge of the insertion rod 20, and the insertion rod 20 is threadedly connected to the inner wall of the rotating cylinder 23. A rotating ring 32 is fixedly sleeved on the outer edge of the rotating cylinder 23.

[0034] In the above structure, through the cooperation of the insert rod 20 and the slot 19, when the mold 31 needs to be fixed on the top of the lower mold 18, simply rotate the rotating ring 32 clockwise, causing the rotating ring 32 to drive the rotating drum 23 to rotate. Utilizing the sleeve between the rotating drum 23 and the transmission belt 24, the transmission belt 24 drives the other two rotating drums 23 to rotate together. At this time, through the threaded connection between the rotating drum 23 and the threaded post 25, the insert rod 20 will slide outward, causing the insert rod 20 to separate from the inner wall of the slot 19. After the mold 31 is placed on the top of the lower mold 18, by aligning the slot 19 on the outer edge of the mold 31 with the slot 19 on the outer edge of the lower mold 18, and rotating the rotating ring 32 counterclockwise, the insert rod 20 is reinserted into the inner wall of the slot 19. This achieves the purpose of fixing and limiting the mold 31, preventing the mold 31 from shaking or becoming unstable during the forging process.

[0035] Working principle: When this device is needed, it can first be used in conjunction with the locking block 28 and the receiving groove 26. Then, when it is necessary to replace the upper die 13 or the lower die 18, simply press the locking block 28 inwards, causing it to compress the spring 27 against the inner wall of the receiving groove 26, resulting in deformation and contraction. At this time, the locking block 28 slides into the receiving groove 26. When the locking block 28 is stored in the receiving groove 26 and separated from the positioning block 10, the sliding rod 12 and the upper die 13 can be removed from the inner wall of the positioning block 10 and the auxiliary lower pressing block 11, allowing for the replacement of the new sliding rod 12 and the upper die 13. This prevents the upper die 13 from affecting the forging efficiency of the die 31 due to prolonged use. Secondly, by using the insertion rod 20 and the slot 19 in conjunction, when the die 31 is placed on top of the lower die 18... To fix the mold, simply rotate the rotating ring 32 clockwise, causing the rotating ring 32 to drive the rotating drum 23 to rotate. The connection between the rotating drum 23 and the transmission belt 24 causes the transmission belt 24 to drive the other two rotating drums 23 to rotate together. At this time, the threaded connection between the rotating drum 23 and the threaded post 25 causes the insertion rod 20 to slide outwards, separating it from the inner wall of the slot 19. Then, after placing the mold 31 on top of the lower mold 18, align the slot 19 on the outer edge of the mold 31 with the slot 19 on the outer edge of the lower mold 18, and rotate the rotating ring 32 counterclockwise to re-insert the insertion rod 20 into the inner wall of the slot 19. This effectively fixes and limits the mold 31, preventing it from shaking or becoming unstable during the forging process.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
