Description

Technical Field

[0001] The invention relates to the technical field of forging devices, and in particular to a reversible forward and reverse forging device. Background Art

[0002] A forging machine is a machine that uses hammering and other methods to make metal materials in a plastic state into workpieces with a certain shape and size and change its physical properties. Forging is a processing technology that is carried out to make objects into the shape people need. The forged objects are tougher.

[0003] Referring to the Chinese invention patent, the publication number is: CN 113492188 B, and the name is: A reversible multi-faceted forging with good clamping effect, by installing a first clamping plate and a second clamping plate, the object can be clamped and the position can be adjusted. The first electric telescopic rod drives the flip bracket to rotate, thereby causing the object to flip, realizing the clamping and flipping functions. After the object is flipped, the second clamping plates are close to each other to realize the clamping function and prevent the object from shifting.

[0004] However, in actual use, there are still some problems with the above invention patent:

[0005] 1. In the forging process, since the volume of the forged parts often exceeds the limit of the bottom area of ​​the forging hammer, frequent movement of the forged parts becomes a necessary operation. However, when the clamping plate in the above invention is used for clamping, for forging parts with a circular center or irregular shape, it is easy to cause loose clamping due to insufficient contact surface, which in turn causes slippage, affecting the forging accuracy and efficiency. In addition, the forged parts are in a high temperature state during the forging process. The rubber material clamping element in the above invention has limited tolerance to the high temperature environment and is prone to thermal aging, softening or even melting, which not only reduces the clamping performance but also increases the risk of equipment failure.

[0006] 2. Forging operations place strict demands on the structural strength and impact resistance of the forging table. If a movable mechanism is integrated at the bottom of the forging table to assist the displacement of forged parts, although it can improve operational flexibility, it will significantly reduce the overall rigidity and impact resistance of the forging table, aggravate structural fatigue caused by long-term high-frequency impact and vibration, and ultimately affect the service life and operational stability of the forging table;

[0007] 3. For long strip forgings, when the on-site flipping method in the above invention is adopted, it is easy for the forgings to accidentally collide with the edge of the forging table due to their long length, which may not only damage the surface of the forgings, affecting their dimensional accuracy and mechanical properties, but also cause impact damage to the forging equipment, reducing the overall operation safety;

[0008] 4. After each forging operation is completed, a large amount of high-temperature iron filings and impurities will remain on the surface of the forging table. The traditional manual cleaning method is not only inefficient and labor-intensive, but also directly exposed to the high-temperature debris environment, posing a safety hazard to the operator.

[0021] Compared with the prior art, the present invention provides a reversible positive and negative forging device, which has the following features:

[0022] Beneficial effects:

[0023] 1. The reversible forward and reverse forging device can drive the control ring to move to different positions on the forging table by controlling the first electric push rod, the second electric push rod and the third electric push rod to work, thereby driving the forging piece to move, without manual movement through clamps, and is easy to operate. The continuous movement of the forging piece can increase the uniformity of forging, thereby ensuring the forging effect. The first electric push rod, the second electric push rod and the third electric push rod are not directly connected to the forging table, thereby ensuring the impact resistance of the forging table.

[0024] 2. The reversible forward and reverse forging device, the control ring pushes the forging to move to the lifting plate, and contracts the fourth electric push rod. At this time, the first electric push rod and the second electric push rod are in a straight line, and the motor at one end of the transmission shaft is started to drive the second electric push rod to rotate, and the first bevel gear drives the second bevel gear and the rotating ring to rotate, driving the telescopic bar and the rotating bar to move, and the contact wheel and the surface of the forging are in contact, so that the forging is firmly fixed, and the lifting plate is lowered and separated from the forging. At this time, a pair of motors are rotated synchronously, driving the first electric push rod and the second electric push rod to rotate at the same time, and the control ring is flipped upward from the outside along the axis of the end block, so that the bottom end of the forging is flipped to the top end, thereby completing the flipping of the forging, realizing the diversity of the control ring function. At the same time, the outside-in and three-point synchronous clamping method is adopted to make the forging more firmly fixed to avoid falling off during the flipping process, which is suitable for forgings of different shapes.

[0025] 3. The reversible forward and reverse forging device moves the lifting plate downward to make it contact with the pressure rod, pushes the pressure rod downward to compress the gas inside the fixed cylinder, and then lowers the lifting plate to make it contact with the pressure plate and push the pressure plate downward. The delayed self-closing valve opens, and the compressed air inside the fixed cylinder enters the connecting pipe and the air cylinder, pushing the push rod to extend, thereby driving the push plate to slide quickly, so that the iron filings on the surface of the forging table fly off the table, thereby cleaning the table. When the compressed air is released, the movement speed of the push plate is increased, so that the iron filings can fly off quickly, and at the same time, it can reduce the iron filings falling onto the forging, which is convenient for forging again.

[0047] Embodiment 3:

[0048] Based on Example 2, Figure 2 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 A reversible forward and reverse forging device, a pushing mechanism 3 is connected to the forging table 1, the pushing mechanism 3 includes a pushing plate 34, one end of the forging table 1 away from the lifting plate 26 is slidably connected to the pushing plate 34, an air cylinder 33 is installed on the side wall of the forging table 1, one end of the air cylinder 33 is slidably connected to a pushing rod 36, one end of the pushing plate 34 is fixed on the pushing rod 36, and an inflation component for inflating the air cylinder 33 is connected to the forging table 1, so that when the air cylinder 33 is inflated, the pushing plate 34 can be pushed to move, thereby facilitating the cleaning of the surface of the forging table 1.

[0049] In the present invention, the inflation assembly includes a fixed cylinder 31, which is installed on the forging table 1. The fixed cylinder 31 is arranged below the lifting plate 26. The top of the fixed cylinder 31 is slidably connected with a pressure rod 37, and the top of the pressure rod 37 is used to contact the bottom end of the lifting plate 26. An air duct 38 connected to the interior is provided on the fixed cylinder 31. A connecting pipe 32 is installed between the fixed cylinder 31 and the air cylinder 33. The air duct 38 is connected to the interior of the air cylinder 33 through the connecting pipe 32. By facilitating the descent of the lifting plate 26 to push the pressure rod 37, the gas is guided to the interior of the air cylinder 33, and the pushing plate 34 is driven to clean the table surface of the forging table 1.

[0050] In the present invention, a protruding component 35 is connected to the pushing plate 34, and the protruding component 35 includes a sliding bar 351. The top of the pushing plate 34 is slidably connected to the sliding bar 351. A first spring 352 is installed between the sliding bar 351 and the pushing plate 34. The top of the sliding bar 351 is a trapezoidal structure. When the control ring 28 moves to both sides, the third electric push rod 241 pushes the sliding bar 351 to contract, and the first spring 352 is compressed. Therefore, when pushing iron filings, the third electric push rod 241 and the sliding bar 351 are disengaged, and the sliding bar 351 is reset to facilitate pushing more iron filings. The top of the sliding bar 351 is a trapezoidal structure, which is convenient for the third electric push rod 241 to press it down.

[0051] In the present invention, a blocking component 39 is connected to the connecting pipe 32, and the blocking component 39 includes a delayed self-closing valve 393. The delayed self-closing valve 393 is installed on the connecting pipe 32, and a pressure plate 391 is slidably connected to the pressure rod 37. A second spring 392 is installed between the pressure plate 391 and the fixed cylinder 31. One end of the pressure plate 391 is fixedly connected to the pressing end of the delayed self-closing valve 393. The delayed self-closing valve 393 can compress the gas inside the fixed cylinder 31. When the compressed air is released, the movement speed of the push plate 34 is increased, so that the iron filings can fly away quickly.

[0052] Working principle: through program control, the first electric push rod 22 and the second electric push rod 23 are contracted, and the third electric push rod 241 is extended, so that the control ring 28 moves to the top of the lifting plate 26, and the forging piece is placed inside the control ring 28. By controlling the first electric push rod 22 and the second electric push rod 23 to extend and the third electric push rod 241 to contract, the control ring 28 can be pulled to move to the bottom end of the forging part of the forging table 1, so that the forging piece is pulled to the forging place. During the forging process, it is often necessary to move the forging piece continuously so that the forging piece is evenly struck. By controlling the first electric push rod 22, the second electric push rod 23 and the third electric push rod 241 to work, the control ring 28 can be driven to move to different positions on the table of the forging table 1, such as: the first electric push rod 22 is extended, the second electric push rod 23 is contracted, and the third electric push rod 241 is contracted, then the control ring 28 is pulled to move to the top of the side close to the second electric push rod 23, so as to facilitate the movement of the forging piece, thereby ensuring the forging effect;

[0053] When the forged piece needs to be flipped, the control ring 28 pushes the forged piece to move onto the lifting plate 26, and contracts the fourth electric push rod 25, thereby driving the lifting plate 26 to descend. When the lifting plate 26 descends, the forged piece moves downward so that the top of the forged piece is flush with the control ring 28. At this time, the first electric push rod 22 and the second electric push rod 23 are in a straight line, and the motor 27 at one end of the transmission shaft 43 is started to drive the second electric push rod 23 to rotate. The first bevel gear 45 at the telescopic end of the second electric push rod 23 rotates accordingly, thereby driving the second bevel gear 46 and the rotating ring 44 to rotate. When the rotating ring 44 rotates, it drives the telescopic bar 42 and the rotating bar 41 to move. The telescopic bar 42 extends from the inside of the rotating bar 41, and the rotating bar 4 1 will be close to the surface of the forged piece, the abutment wheel 52 abuts against the surface of the forged piece, and can better adapt to different shapes of the forged piece under the rotation of the rotating block 51, so as to fix the forged piece firmly, and make the lifting plate 26 descend and separate from the forged piece. At this time, the pair of motors 27 are rotated synchronously, driving the first electric push rod 22 and the second electric push rod 23 to rotate at the same time, and the third electric push rod 241 limits the rotation of the clamp 242, so that the control ring 28 is turned upward from the outside along the axis of the end block 29, so that the bottom end of the forged piece is turned to the top end, driving the lifting plate 26 to rise, and controlling the motor 27 at one end of the transmission shaft 43 to rotate, so as to release the fixation of the forged piece, and then the reverse side of the forged piece can be moved and forged again by moving the control ring 28;

[0054] After forging is completed, the forged piece is moved to the lifting plate 26, and the fourth electric push rod 25 is retracted to move the lifting plate 26 downward, so that it contacts the pressure rod 37, and the pressure rod 37 is pushed downward to compress the gas inside the fixed cylinder 31, and then the lifting plate 26 is lowered to contact the pressure plate 391, and the pressure plate 391 is pushed downward to open the delayed self-closing valve 393, and the compressed air inside the fixed cylinder 31 enters the connecting pipe 32 and the air cylinder 33, pushing the push rod 36 to extend, thereby driving the push plate 34 to slide quickly, so that the iron filings on the surface of the forging table 1 fly off the table surface, thereby achieving the cleaning effect of the table surface, and the compressed air is released. The movement speed of the push plate 34 can make the iron filings fly away quickly and reduce the chance of them falling onto the forged parts. After the forged parts are removed, the control ring 28 will serve as a reset base. After the lifting plate 26 rises, the delayed self-closing valve 393 will automatically close after a certain period of time. The control ring 28 will push the push plate 34 to reset within the closing time of the delayed self-closing valve 393 to facilitate working again. When the control ring 28 moves to both sides, the third electric push rod 241 pushes the sliding bar 351 to contract and the first spring 352 to compress. Therefore, when pushing the iron filings, the third electric push rod 241 and the sliding bar 351 are disengaged, and the sliding bar 351 is reset to facilitate pushing more iron filings.

[0055] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
