Description

Technical Field

[0001] This invention relates to the field of shaft forging technology, specifically to an auxiliary tool for local heating forging of shaft forgings. Background Technology

[0002] During the forging process of shaft parts, the workpiece needs to be heated. However, some shaft forgings only require local deformation during forging, so local heating is necessary, and auxiliary tools are used to assist in bending and deformation.

[0003] For example, patent CN205110645U discloses an auxiliary tool for local heating forging of shaft forgings. This patent can assist in completing the forging process of shaft parts, thereby saving heating energy, improving forging efficiency, and simplifying the process. However, in actual use, there are problems. The shaft forgings need to be moved to a medium-frequency heating furnace for heating first, and then the forgings are placed in a mold. In actual operation, the forgings need to be transferred multiple times, resulting in low overall processing efficiency. At the same time, the forgings removed from the medium-frequency heating furnace are at a high temperature. If they are accidentally dropped during personnel handling, it can easily cause dangerous accidents, posing certain safety hazards. Summary of the Invention

A forging machine body is disposed on one side of the auxiliary housing, and a mold is disposed on the top surface of the middle part of the forging machine body. The adjustment assembly is disposed inside the auxiliary housing and includes a reduction motor. The reduction motor is disposed at the upper end of the adjustment assembly, and a screw is connected to the output end of the reduction motor. A drive plate is threadedly connected to the outer side of the middle part of the screw, and an adjustment cylinder is slidably connected to one end of the drive plate.

A drive frame is fixed to one side of the sliding column, and a guide plate is slidably connected to the outer side of one end of the drive frame. An induction heating coil is disposed inside the other end of the drive frame, and a support plate is disposed above the other end of the drive plate, with a top rod fixed to the top of the support plate.

[0006] Furthermore, the swing plate is rotatably connected to the auxiliary housing, and the auxiliary housing is fixedly connected to the guide plate.

[0007] Furthermore, the auxiliary housing is internally equipped with a bending assembly, which includes a drive ring. One end of the drive plate is fitted with the drive ring. A fork plate is rotatably connected to one side of the inner wall of the auxiliary housing, and a drive sleeve is fixed to one side of the fork plate. A slide rod is slidably connected to the upper end of the drive sleeve, and a slide block is rotatably connected to the top of the slide rod. A spring seat is slidably connected to the upper end of the slide block, and a strike rod is fixed to one end of the spring seat. A strike head is fixed to one end of the strike rod, and a counterweight is fitted to the other end of the strike rod. A pulley is rotatably connected to the lower outer side of the counterweight.

[0008] Furthermore, the slide block is slidably connected to the auxiliary housing, and the impact rod is also slidably connected to the auxiliary housing.

[0009] Furthermore, the impact head and the impact rod form a Y-shaped structure, and the impact rod is slidably connected to the guide plate.

[0010] Furthermore, the bottom of the drive plate is provided with a discharge assembly, and the discharge assembly includes an adjusting rod. The adjusting cylinder is internally threaded with the adjusting rod, and a protruding post is fixed at the bottom of the adjusting cylinder. A rotating plate is slidably connected to the outside of the protruding post, and a connecting rod is rotatably connected to one end of the rotating plate. A toothed plate is rotatably connected to one end of the connecting rod, and a guide rod is arranged on one side of the toothed plate.

[0011] Furthermore, the adjusting rod is rotatably connected to the drive plate, and the drive plate is slidably connected to the protruding post.

[0012] Furthermore, the drive plate is rotatably connected to the rotating plate, and the drive plate is slidably connected to the guide rod.

[0013] Furthermore, the forging machine body is internally rotatably connected to a double gear shaft, and one end of the double gear shaft is meshed with a bevel gear. The bevel gear is internally fitted with a threaded sleeve, and the threaded sleeve is internally threaded with a stud, and a top plate is fixed to the top of the stud.

[0014] Furthermore, the top plate is slidably connected to the forging machine body, and the forging machine body is rotatably connected to the screw sleeve.

[0015] This invention provides an auxiliary tool for local heating forging of shaft forgings, which has the following beneficial effects: 1. The present invention uses a geared motor to drive the drive plate to rise and fall via a screw, which can control the induction heating coil to move precisely toward or away from the workpiece, achieving automatic avoidance and centering. At the same time, it can also drive the top rod to complete the automatic lifting and lowering of the blank, realizing the automation of local heating of the blank. This not only eliminates the dangerous link of manually handling high-temperature blanks and improves inherent safety, but also significantly shortens the process interval and improves production efficiency. Moreover, the entire set of actions is controlled by a single power source, with a highly integrated structure and smooth and reliable operation.

[0016] 2. The downward movement of the drive plate of this invention can drive the drive ring, fork plate and other components, so that the impact rod drives the bending impact head to impact the blank. Compared with the existing manual operation method, it is more labor-saving. The specially designed impact head can ensure the accuracy of the bending direction. The elastic buffer system composed of spring seat can effectively absorb impact vibration, protect precision transmission components, and extend the service life of the equipment. The counterweight block uses inertia to enhance the impact effect and improve the initial forming efficiency.

[0017] 3. After forging is completed, the drive wheel can be retracted by rotating the adjusting rod, making it misaligned with the swing plate and disconnecting the transmission from the adjusting component to avoid interfering with subsequent unloading. At the same time, the toothed plate will automatically move towards the double gear shaft. When the drive plate moves upward, it will be converted into a slow but high-thrust initial ejection of the top plate through the deceleration and torque-increasing transmission chain composed of the toothed plate and double gear shaft, which can effectively overcome the adhesion of the upper end of the workpiece. Then the drive plate directly pushes the support plate to achieve rapid lifting. This two-stage ejection mode takes into account both quality and efficiency. The entire mode switching only requires the operation of one adjusting rod, which is extremely simple and reduces the skill requirements of the operator. Attached Figure Description

[0020] Please see Figures 1 to 4 This invention provides a technical solution: an auxiliary tool for local heating forging of shaft forgings, comprising an auxiliary housing 1 and an adjusting assembly 4. A forging machine body 2 is disposed on one side of the auxiliary housing 1, and a mold 3 is disposed on the top surface of the middle part of the forging machine body 2. The adjusting assembly 4 is disposed inside the auxiliary housing 1, and includes a reduction motor 401. The reduction motor 401 is disposed at the upper end of the interior of the adjusting assembly 4, and the output end of the reduction motor 401 is connected to a screw 402. A drive plate 403 is threadedly connected to the outer side of the middle part of the screw 402, and an adjusting cylinder 404 is slidably connected to one end of the drive plate 403. One end of the adjusting cylinder 404 is rotatably connected to... A drive wheel 405 is provided, and a swing plate 406 is abutted on one side of the drive wheel 405. A counterweight plate 407 is installed on one side of the middle part of the swing plate 406. A sliding column 408 is slidably connected inside the upper end of the swing plate 406. A drive frame 409 is fixed on one side of the sliding column 408. A guide plate 410 is slidably connected to the outer side of one end of the drive frame 409. The swing plate 406 is rotatably connected to the auxiliary housing 1. The auxiliary housing 1 is fixedly connected to the guide plate 410. An induction heating coil 411 is provided inside the other end of the drive frame 409. A support plate 412 is provided above the other end of the drive plate 403. A top rod 413 is fixed on the top of the support plate 412. The specific operation is as follows: Start the reduction motor 401, which drives the drive plate 403 to move downward along its axis via the screw 402. When the drive wheel 405 moves to the lower end of the swing plate 406, the counterweight plate 407 will pull the swing plate 406 under the action of gravity, causing it to rotate with the lower end as the center. The upper part will then pull the drive frame 409 through the slide column 408, causing the induction heating coil 411 to move towards the guide plate 410, thus making room for the upper part of the mold 3 so that personnel can place the shaft forging blank into the mold 3. When it is necessary to locally heat the upper end of the blank, simply control the screw 402 to rotate in the opposite direction via the reduction motor 401. When the drive plate 403 moves, it drives the drive wheel 405 upward to abut against the lower side of the swing plate 406, and then pushes the swing plate 406 to rotate. This allows the drive frame 409 to move via the sliding column 408. When the swing plate 406 rotates to a vertical position, the induction heating coil 411 moves directly above the forging, aligning its central axis with the axis of the forging. Then, when the drive wheel 405 continues to move upward, the guide plate 410 limits the drive frame 409, preventing the swing plate 406 from rotating. This positions the movement distance of the induction heating coil 411 and prevents it from interfering with the subsequent upward movement of the drive plate 403. When the drive plate 403 moves upward, it drives the ejector rod 413 to move via the support plate 412, thus lifting the shaft forging blank and extending the part to be processed into the induction heating coil 411. This allows for precise local heating of specific parts of the forging according to process requirements. After heating, when forging is needed, simply controlling the drive plate 403 to move downward will cause the ejector rod 413 to lower and reset the workpiece. Subsequently, the drive frame 409 will move the induction heating coil 411 away from above the mold 3, avoiding obstruction between the mold 3 and the hammer of the forging machine body 2. Therefore, this design eliminates the need for heating. The manual transfer of high-temperature billets not only significantly shortens the waiting time between processes and improves production efficiency, but also fundamentally eliminates the burns and safety risks caused by manual handling of high-temperature forgings, achieving inherent safety. Furthermore, the entire process, such as the avoidance, resetting, and centering of the induction heating coil 411, as well as the lifting and lowering of the forging, is controlled by a single power source: the geared motor 401 drives the drive plate 403 through the screw 402. This highly integrated design connects multiple actions that originally required independent operation into a coherent automated process, achieving seamless connection from loading to heating to forging preparation.

[0021] Please see Figures 3 to 4The auxiliary housing 1 has a bending assembly 5 inside, which includes a drive ring 501. The drive ring 501 is mounted on one end of the drive plate 403. A fork plate 502 is rotatably connected to one side of the inner wall of the auxiliary housing 1, and a drive sleeve 503 is fixed to one side of the fork plate 502. A slide rod 504 is slidably connected inside the upper end of the drive sleeve 503, and a slide block 505 is rotatably connected to the top of the slide rod 504. A spring seat 5 is slidably connected inside the upper end of the slide block 505. 06, and one end of the spring seat 506 is fixed with a strike rod 507, the slide 505 is slidably connected to the auxiliary housing 1, and the strike rod 507 is also slidably connected to the auxiliary housing 1. One end of the strike rod 507 is fixed with a strike head 508, and the other end of the strike rod 507 is equipped with a counterweight 509. The lower outer side of the counterweight 509 is rotatably connected to a pulley 510. The strike head 508 and the strike rod 507 form a Y-shaped structure, and the strike rod 507 is slidably connected to the guide plate 410. The specific steps are as follows. After heating the shaft forging blank, simply controlling the drive plate 403 to continue moving downwards will cause the drive ring 501 to slide into the groove of the fork plate 502, allowing the drive sleeve 503 to rotate with its lower end as the fulcrum. This will then drive the impact rod 507 to move towards the upper end of the shaft forging blank via the slide rod 504, slide block 505, and spring seat 506, causing the impact head 508 to initially bend the upper end of the shaft forging blank. When the drive plate 403 rises, it will push the fork plate 502 to reverse its direction. Similarly, by rotating the rotor to reset, the impact rod 507 can drive the impact head 508 to move back. Therefore, when assisting in bending shaft forging blanks, this application can drive the impact rod 507 to impact the blank by changing the position of the drive plate 403. Compared with the prior art, which requires manual operation of the impact rod 507, this method is more labor-saving and reduces operator fatigue. The curved impact head 508 can also act as a guide during impact, preventing irreversible bending direction when bending the upper end of the blank. The controlled skew ensures the accuracy and repeatability of the initial bending shape, laying a good foundation for subsequent precision forging. At the same time, the spring seat 506 forms an elastic buffer between the slide 505 and the impact rod 507. It can effectively absorb the huge impact force and vibration generated at the moment of impact, and prevent these harmful energies from being directly transmitted to precision transmission components such as the screw 402 and the geared motor 401. This significantly reduces the impact load and fatigue damage of the mechanism, and plays a key protective role in extending the service life of the entire equipment. Furthermore, when the impact rod 507 slides, the counterweight 509 will also move on the top of the auxiliary housing 1 through the pulley 510. By utilizing the inertia of the counterweight 509, it can provide an additional impact momentum to the impact rod 507 at the moment of impact, which is equivalent to a built-in "inertial hammer". This significantly enhances the impact force and effect without increasing the driving power, accelerates the deformation speed of the blank, and improves the efficiency of the initial forming.

[0022] Please see Figures 5 to 7 The bottom of the drive plate 403 is provided with a discharge assembly 6, which includes an adjusting rod 601. The adjusting cylinder 404 is internally threaded with the adjusting rod 601, and a protrusion 602 is fixed at the bottom of the adjusting cylinder 404. The adjusting rod 601 is rotatably connected to the drive plate 403, and the drive plate 403 is slidably connected to the protrusion 602. A rotating plate 603 is slidably connected to the outside of the protrusion 602, and a connecting rod 604 is rotatably connected to one end of the rotating plate 603. A toothed plate 605 is rotatably connected to one end of the connecting rod 604, and one side of the toothed plate 605... A guide rod 606 is installed, the drive plate 403 is rotatably connected to the rotating plate 603, and the drive plate 403 is slidably connected to the guide rod 606. A double gear shaft 607 is rotatably connected inside the forging machine body 2, and a bevel gear 608 is meshed at one end of the double gear shaft 607. A threaded sleeve 609 is installed inside the bevel gear 608, and a stud 610 is threadedly connected inside the threaded sleeve 609. A top plate 611 is fixed to the top of the stud 610. The top plate 611 is slidably connected to the forging machine body 2, and the forging machine body 2 is rotatably connected to the threaded sleeve 609. The specific operation is as follows: After the hammer on the main body 2 of the control forging machine forges the upper end of the shaft forging, the worker rotates the adjusting rod 601. Since the drive plate 403 restricts the rotation of the adjusting cylinder 404 through the protrusion 602, the adjusting cylinder 404 can be driven to retract into the drive plate 403 through the threaded groove on the adjusting rod 601. The drive wheel 405 will then be misaligned with the swing plate 406. Subsequently, when the drive plate 403 moves upward, it will not drive the adjusting component 4 to work, thus avoiding obstruction of the upper end of the shaft forging during unloading. At the same time, during the synchronous sliding process of the adjusting cylinder 404 driving the protrusion 602, it will also push... One end of the rotating plate 603 rotates around the center of the bottom of the drive plate 403. The other end of the rotating plate 603 pushes the toothed plate 605 through the connecting rod 604, causing it to move towards the double gear shaft 607 under the guidance of the guide rod 606. At this time, the toothed plate 605 will be located below the double gear shaft 607. Subsequently, when the drive plate 403 moves upward, as the toothed plate 605 meshes with one end of the double gear shaft 607, it will drive the threaded sleeve 609 to rotate synchronously through the bevel gear 608. Since the top plate 611 restricts the rotation of the stud 610 under the limit of the forging machine body 2, the rotation of the stud 610 can be controlled. The top plate 611 pushes the support plate 412, which in turn moves the ejector rod 413 upward, ejecting the product from the mold 3. During this process, the speed reduction and torque amplification transmission chain formed by the double gear shaft 607 and the bevel gear 608 converts the relatively fast upward speed of the drive plate 403 into a slow, high-thrust lifting motion of the top plate 611. This "slow and stable" initial ejection method effectively overcomes the adhesion and static friction between the workpiece and the upper cavity of the mold 3, preventing workpiece deformation or surface damage caused by sudden impact ejection. Subsequently, when the drive plate 403 contacts the support plate 412, the drive source of the support plate 412 will... The top plate 611 switches to the drive plate 403, which increases the upward movement speed of the ejector rod 413. This allows the product to be ejected quickly after overcoming the adhesion between the product and the mold 3 with a larger lifting force. This two-stage ejection mode of "slow initial speed and large thrust followed by rapid lifting" minimizes the ejection cycle and improves overall production efficiency while ensuring demolding quality. Furthermore, the entire complex mode switching process can be completed with a single click by the worker rotating the adjustment rod 601, greatly simplifying the operation, reducing the skill requirements for operators, and minimizing adjustment time.

[0023] In summary, this auxiliary tool for local heating and forging of shaft-type forgings is used as follows: First, start the geared motor 401, which drives the drive plate 403 to move downward along its axis via the screw 402. When the drive wheel 405 moves to the lower end of the swing plate 406, the counterweight plate 407 will pull the swing plate 406 under the action of gravity, causing it to rotate with the lower end as the center. The upper part will then pull the drive frame 409 through the slide column 408, causing the induction heating coil 411 to move towards the guide plate 410, thus making room for the upper part of the mold 3. Next, the worker places the shaft forging blank into mold 3, and then uses the controller to make the reducer motor 401 control the screw 402 to rotate in the opposite direction. The drive plate 403 will drive the drive wheel 405 to move upward and abut against the lower side of the swing plate 406. Then, pushing the swing plate 406 to rotate will drive the drive frame 409 to move through the sliding column 408. When the swing plate 406 rotates to a vertical position, the induction heating coil 411 will move to directly above the forging, aligning its central axis with the axis of the forging. Then, when the drive wheel 405... As it continues to move upward, the guide plate 410 will limit the drive frame 409, preventing the swing plate 406 from rotating. This allows the movement distance of the induction heating coil 411 to be positioned, without interfering with the subsequent rise of the drive plate 403. When the drive plate 403 moves upward, it will drive the push rod 413 to move through the support plate 412, thus lifting the shaft forging blank and extending the part to be processed into the induction heating coil 411. This allows for precise local heating of specific parts of the forging according to process requirements. Next, after heating, simply controlling the drive plate 403 to move downwards will cause the ejector rod 413 to lower and reset the workpiece. During this process, the drive frame 409 will also move the induction heating coil 411 away from above the mold 3 to avoid obstructing the connection between the mold 3 and the hammer head of the forging machine body 2. Subsequently, as the drive plate 403 continues to move downwards, the drive ring 501 will slide into the groove of the fork plate 502, allowing the drive sleeve 503 to rotate with its lower end as the fulcrum. This will then drive the slide rod 504, slide block 505, and spring seat 506 to rotate. The impact bar 507 moves towards the upper end of the shaft forging blank, causing the impact head 508 to initially bend the upper end of the shaft forging blank. When the drive plate 403 rises, it pushes the fork plate 502 to rotate in the opposite direction and reset. Similarly, the impact bar 507 can drive the impact head 508 to move back. When the impact bar 507 slides, the counterweight 509 will also move on the top of the auxiliary housing 1 through the pulley 510. By utilizing the inertia of the counterweight 509, the impact force and effect are enhanced, the deformation speed of the blank is accelerated, and the efficiency of the initial forming is improved. Then, after the hammer on the main body 2 of the control forging machine forges the upper end of the shaft forging, the worker rotates the adjusting rod 601. Since the drive plate 403 restricts the rotation of the adjusting cylinder 404 through the protrusion 602, the adjusting cylinder 404 can be driven to retract into the drive plate 403 through the threaded groove on the adjusting rod 601. The drive wheel 405 will then be misaligned with the swing plate 406. When the drive plate 403 moves upward, it will not drive the adjusting component 4 to work, thus avoiding obstruction of the upper end of the shaft forging during unloading. At the same time, during the synchronous sliding of the adjusting cylinder 404 and the protrusion 602, it will also push one end of the rotating plate 603, causing the rotating plate 603 to rotate around the center of the bottom of the drive plate 403. The other end of the rotating plate 603 will push the toothed plate 605 through the connecting rod 604, causing it to move towards the double gear shaft 607 under the guidance of the guide rod 606. At this time, the toothed plate 605 will be located below the double gear shaft 607. Finally, when the drive plate 403 moves upward, as the toothed plate 605 meshes with one end of the double gear shaft 607, the bevel gear 608 drives the screw sleeve 609 to rotate synchronously. Since the top plate 611 restricts the rotation of the stud 610 under the limit of the forging machine body 2, it can control the stud 610 to push the support plate 412 through the top plate 611 to drive the ejector rod 413 to move upward, thus ejecting the product from the mold 3. Subsequently, when the drive plate 403 contacts the support plate 412, the drive source of the support plate 412 will switch from the top plate 611 to the drive plate 403. The drive plate 403 can increase the upward movement speed of the ejector rod 413, so that after overcoming the adhesion between the product and the mold 3 with a larger lifting force, the product can be ejected quickly. This two-stage ejection mode, while ensuring the demolding quality, shortens the ejection cycle to the maximum extent and improves the overall production efficiency.
