Description

Technical Field

[0001] This invention belongs to the field of forging processing technology, specifically relating to a processing device for automotive parts forgings. Background Technology

[0002] Forging is a common metal processing technique that involves applying pressure to metal materials to induce plastic deformation, thereby obtaining workpieces with the desired shape, size, and properties. Forging can not only change the shape of metals but also significantly improve their internal structure and enhance their mechanical properties.

[0003] In the manufacturing process of oil bath air filters or engine filters, magnesium alloys are the lightest metal structural material currently used in engineering applications. Forged magnesium alloy parts are usually preferred, as they can reduce weight and help lower the vehicle's center of gravity, thus reducing the load on the mounting brackets.

[0004] Existing magnesium alloy forging technology typically employs a one-time integral forming process. When processing parts with grooves distributed on the surface, the mold cavity is precisely equipped with several sets of guide reinforcing ribs that match the geometric dimensions of the workpiece grooves. These ribs will embed into the corresponding grooves of the parts during the mold closing process. Since the metal billet needs to simultaneously complete large-area spreading and filling of deep and narrow grooves, the deformation resistance increases sharply, requiring extremely high tonnage of the hydraulic press.

[0005] Furthermore, the turbulent metal flow in traditional processes can easily lead to defects such as folding and cracking at the root of the ribs, especially for difficult-to-form materials such as magnesium alloys. During one-time forming, the protruding parts of the mold are subjected to transient impacts and high-frequency friction, which can easily lead to wear and thermal fatigue, resulting in a reduction in the service life of the mold. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an automotive parts forging processing device to solve the problems mentioned in the background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution: An automotive parts forging processing device includes a base component and a mold component. The mold component includes a fixed mold, a mold cavity, and grooves. The fixed mold is fixedly arranged in the base component. The mold cavity is provided in the middle of the fixed mold, and a plurality of grooves are provided on the bottom surface of the mold cavity. A traction rod assembly, wherein the traction rod assembly is movably mounted on the base component and is linked with the base component; A rib assembly includes a bottom slide groove, a slide frame, a first inclined slide platform, a second inclined slide platform, a first transmission slide platform, a second transmission slide platform, a first rib plate, and a second rib plate. The bottom slide groove is fixedly arranged on the bottom side of the base component. The slide frame is slidably disposed in the bottom slide groove. A plurality of first inclined slide platforms and second inclined slide platforms are fixedly arranged on the slide frame. A first transmission slide platform and a second transmission slide platform are slidably arranged on the first inclined slide platform and the second transmission slide platform, respectively. A first rib plate and a second rib plate are fixedly assembled on the first transmission slide platform and the second transmission slide platform, respectively. The first rib plate and the second rib plate are slidably inserted into a plurality of slots.

[0008] As a further embodiment of the present invention, the base component includes a base, a mold base, guide pillars, a top plate, a hydraulic press, and a movable template. The base is equipped with a mold base, and a plurality of guide pillars are fixedly arranged on the mold base. The top plate is fixedly assembled on the top of the guide pillars, and a hydraulic press is also assembled on the top plate. The movable template is slidably arranged on the guide pillars and is assembled and connected to the movable shaft of the hydraulic press.

[0009] As a further embodiment of the present invention, the traction rod assembly includes a traction rod, a cone head, a fixing block, and a transmission plate. The traction rod is slidably arranged in the base and the mold base. The top of the traction rod is provided with a cone head, and the bottom of the traction rod is fixedly connected to the fixing block. The transmission plate is movably arranged in the base and is linked with the fixing block.

[0010] As a further embodiment of the present invention, the traction rod assembly further includes a first inclined groove surface, a second inclined groove surface, a pin, a slide, and a rack. One end of the fixed block is provided with the first inclined groove surface, and the transmission plate is provided with the second inclined groove surface facing the fixed block. A pin is also rotatably mounted on the transmission plate. One end of the pin is fixedly connected to the slide. The slide is elastically slidably arranged in the base. A rack is also provided at the other end of the transmission plate.

[0011] As a further embodiment of the present invention, the rib assembly further includes a side rack, an adjusting gear, a worm gear, a worm, and a central gear. The side rack is fixedly arranged on one side of the carriage. One end of the adjusting gear meshes with the side rack, and the other end of the adjusting gear is coaxially fixedly fitted with a worm gear. One end of the worm meshes with the worm gear, and the other end of the worm is driven by the central gear. The central gear and the rack are movably connected.

[0012] As a further embodiment of the present invention, the automotive parts forging processing device further includes a traction assembly, which includes a cylinder seat, a central hole, a claw plate, a traction claw, a reset surface, a bayonet, and a reset post. The cylinder seat is fixedly assembled to the bottom of the moving template, and a central hole is provided in the middle of the cylinder seat. One end of the claw plate is fixedly connected to the cylinder seat, and several traction claws are elastically rotatably mounted on the claw plate in the circumferential direction. A reset surface is provided on the top of the traction claw, and a bayonet is provided on the bottom of the traction claw. The reset post is fixedly installed on the top plate and is concentrically arranged with the cylinder seat.

[0013] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art: This invention effectively avoids the extreme deformation of metal billets undergoing simultaneous large-area spreading and deep, narrow groove filling in a single forging process by dynamically controlling the lifting sequence of the ribs within the die cavity. This staged forming method allows the metal material to first complete the filling and preliminary compaction of the die cavity body with lower flow resistance, establishing a more favorable prestress and temperature field distribution. This significantly reduces the peak demand on the maximum forging tonnage of the hydraulic press, not only improving forming efficiency but also creating thermodynamic conditions for subsequent extrusion of locally high-rib sections, thus ensuring forming quality while reducing equipment load.

[0014] Furthermore, the device employs a sequential forming strategy, which makes the plastic flow of metal more stable and orderly, significantly reducing the risk of turbulence, shear bands, and even folding defects when flowing through the root of the reinforcing ribs. Step-by-step forming effectively reduces the transient impact force and high-speed frictional heat load peak borne by the protruding parts of the mold, thereby significantly improving the service life of the mold. Especially for difficult-to-form materials such as magnesium alloys, this structure alleviates the process problems such as easy cracking and difficult filling by precisely controlling the local strain rate and deformation sequence, providing a reliable guarantee for the stable production of high-quality complex forgings.

[0015] Furthermore, the traction rod assembly and the rib assembly form a precision linkage system through mechanisms such as inclined grooves, gears, and worm gears. This system can automatically drive the ribs to make slight adjustments during the lifting phase of the forging press and automatically separate them during the pressing phase. This ensures that the adjustment operation is only performed when the equipment is under no load. The worm gear mechanism has a self-locking function to prevent slippage during forging and to ensure forming accuracy. The entire system enables controllable adjustment of the rib height and the timing of the actions, improving process repeatability and automation, and providing an efficient and stable solution for complex multi-step forging operations.

Detailed Implementation

[0025] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Please see Figures 1-8 An automotive parts forging processing apparatus according to one embodiment of the present invention has a first direction x, a second direction z, and a third direction z. The automotive parts forging processing apparatus includes a base component 1 and a mold component 2. The mold component 2 includes a fixed mold 201, a mold cavity 202, and a groove 203. The fixed mold 201 is fixedly arranged in the base component 1. The mold cavity 202 is provided in the middle of the fixed mold 201. The bottom surface of the mold cavity 202 is provided with... Several grooves 203; a traction rod assembly 3, which is movably arranged on the base member 1 and linked with the base member 1; a rib assembly 4, which includes a bottom slide groove 401, a slide frame 402, a first inclined slide 403, a second inclined slide 404, a first transmission slide 405, a second transmission slide 406, a first rib plate 409, and a second rib plate 410. The bottom slide groove 401 is fixedly arranged on the bottom side of the base member 1, and the slide frame 402 is limited and slidably arranged. In the bottom slide groove 401, a plurality of first inclined slides 403 and second inclined slides 404 are fixedly arranged on the slide frame 402. A first transmission slide 405 and a second transmission slide 406 are obliquely slidably arranged on the first inclined slides 403 and the second inclined slides 404, respectively. A first rib 409 and a second rib 410 are fixedly assembled on the first transmission slide 405 and the second transmission slide 406, respectively. The first rib 409 and the second rib 410 are slidably inserted into the plurality of slides 403 and the second inclined slide 404. In the groove 203; the base component 1 includes a base 101, a mold base 102, guide pillars 103, a top plate 104, a hydraulic press 105, and a moving template 106. The mold base 102 is mounted on the base 101, and a plurality of guide pillars 103 are fixedly arranged on the mold base 102. The top plate 104 is fixedly mounted on the top of the guide pillars 103, and the hydraulic press 105 is also mounted on the top plate 104. The moving template 106 is slidably arranged on the guide pillars 103 and is connected to the movable shaft of the hydraulic press 105.

[0027] In practical application, the main structure of this automotive parts forging processing device consists of a base component 1 and a mold component 2. The base component 1 includes a base 101, a mold base 102, guide pillars 103, a top plate 104, a hydraulic press 105, and a moving template 106. The mold base 102 is rigidly mounted on the base 101, and several vertical guide pillars 103 are fixedly arranged circumferentially on the mold base 102. The top plate 104 is fixed to the top of the guide pillars 103 by high-strength bolts, forming a rigid support frame. The hydraulic press 105 is mounted at the center of the top plate 104. The moving template 106 is slidably sleeved on the guide pillars 103 through linear bearings and rigidly connected to the piston rod end of the hydraulic press 105, so that the hydraulic press 105 can precisely control the axial directional sliding of the moving template 106 along the guide pillars 103. The mold component 2 includes a fixed mold 201, a mold cavity 202, a groove 203, and a moving mold 204. The fixed mold 201 is fastened to the mold base 105 by positioning pins and bolts. In the cavity of the base 102, the upper surface of the fixed mold 201 is precision machined with a cavity 202. The bottom surface of the cavity 202 is provided with several parallel grooves 203 along a specific direction. The moving mold 204 is fixedly installed at the bottom of the moving template 106. Its working surface corresponds to the cavity 202 of the fixed mold 201. Driven by the hydraulic press 105, the moving mold 204 can perform precise reciprocating motion along the vertical direction, i.e., the z-axis, thereby applying forging pressure to the metal billet placed in the cavity 202, causing it to undergo plastic deformation and fill the cavity.

[0028] Within the groove 203 on the bottom surface of the mold cavity 202, a first rib plate 409 and a second rib plate 410 from the rib assembly 4 are arranged. The first rib plate 409 and the second rib plate 410 are movably fitted into the groove 203 along the z-axis direction, together forming a movable cavity bottom wall. This structural design allows the first rib plate 409 and the second rib plate 410 to have two key working states: a retracted state and an ejected state. At the initial stage of the forging cycle, i.e., before the start of a single forging operation, both the first rib plate 409 and the second rib plate 410 are in the retracted state. When forging is completed, both the first rib plate 409 and the second rib plate 410 are in the ejected state. When both the first rib plate 409 and the second rib plate 410 are in the retracted state... In the initial state, its top forming surface is coplanar with the bottom surface of the mold cavity 202, forming a complete and flat bottom of the cavity, which does not hinder the initial flow of the blank. As the multi-step or multi-die forging operation continues, the blank undergoes multiple deformations under cyclic forging, and the metal volume is continuously redistributed and gradually fills the complex space of the mold cavity 202. During this process, the first rib 409 and the second rib 410 are coordinated and controlled by the traction rod assembly 3 and the rib assembly 4, and begin to be lifted precisely and gradually in the positive z-axis direction. This dynamic adjustment ensures that the plastic metal can maintain a relatively uniform flow in the main space of the mold cavity before the blank is finally formed, without being blocked or disturbed by the prematurely protruding rib structure.

[0029] Because magnesium alloys have a close-packed hexagonal crystal structure, the number of independent slip systems at room temperature is very small, resulting in extremely poor room temperature plasticity. Their plastic forming ability is significantly lower than that of conventional steel and aluminum alloys. The flow stress of magnesium alloys is extremely sensitive to strain rate, exhibiting a strong positive correlation; that is, the ability to resist deformation increases sharply with increasing deformation rate. If the flow velocity of the billet at the ribs is too fast, it will quickly trigger work hardening, leading to filling difficulties or even cracking. Simultaneously, magnesium alloys have a narrow forging temperature window; too low a temperature results in insufficient plasticity and easily causes cracks, while too high a temperature, especially above 400°C, easily leads to grain coarsening and even overheating, damaging product performance. The advantage of this rib structure is that it effectively avoids the metal simultaneously undergoing large... Extreme deformation conditions involving radial spreading and deep, narrow rib filling can significantly reduce the peak demand on the maximum forging tonnage of hydraulic equipment by delaying the formation of key protrusions at the bottom of the cavity. The working principle is to allow the metal material to first fill and compact the main body of the cavity with lower flow resistance. At this stage, a more favorable prestress and temperature field distribution are established, creating more optimized thermodynamic conditions for the extrusion of grooves on the surface of the billet in the subsequent stage. This helps to reduce the probability of turbulence, shear bands, and even folding defects when the metal flows through the root area of ​​the ribs. From the perspective of mold load, step-by-step forming can significantly reduce the peak heat load generated by the transient impact force and high-speed friction on the protrusions on the mold, i.e., the corresponding ribs, which is beneficial to improving the mold life.

[0030] Furthermore, for the preparation of magnesium alloy forgings, this rib structure with precisely controllable activity timing can further optimize the metal flow path and control the local strain rate and deformation sequence. This can effectively alleviate a series of process defects faced by magnesium alloys in conventional forging forming, such as difficulty in flow filling, easy cracking, high equipment tonnage requirements, and large impact on the mold. This provides a new solution for achieving stable production of high-quality complex magnesium alloy forgings.

[0031] Furthermore, the initial protrusion heights of the first rib 409 and the second rib 410 relative to the bottom surface of the mold cavity 202 are set to be unequal. During the active lifting process along the z-axis, the system can differentiate the lifting rate of the first rib 409 and / or the second rib 410. By precisely adjusting the displacement speed curves of each rib, it can ensure that different ribs accurately reach their preset final heights in the final stage of the forging process.

[0032] Please see Figure 5In a preferred embodiment of the present invention, the traction rod assembly 3 includes a traction rod 301, a cone head 302, a fixing block 303, and a transmission plate 305. The traction rod 301 is slidably arranged in the base 101 and the mold base 102. The top of the traction rod 301 is provided with a cone head 302. The bottom of the traction rod 301 is fixedly connected to the fixing block 303. The transmission plate 305 is movably arranged in the base 101 and is linked with the fixing block 303.

[0033] In practical application, the traction rod assembly 3 consists of a traction rod 301, a cone head 302, a fixing block 303, and a transmission plate 305. The traction rod 301 is slidably installed between the base 101 and the mold base 102 in the vertical direction. It has a cone-shaped head at its top and a fixing block 303 rigidly connected to its bottom. The transmission plate 305 is movably disposed inside the base 101 and is linked to the fixing block 303 via a mechanical interface. When the traction rod 301 moves along the positive z-axis, it directly drives the transmission plate 305 to move synchronously through the fixing block 303 at its bottom, thereby transmitting power to the rib assembly 4 and triggering its linkage response. During this process, the traction rod 301, the fixing block 303, and the transmission plate 305 together form a rigid transmission chain, ensuring that power is effectively transmitted from the traction rod 301 to the rib. Component 4 enables precise height adjustment of the first stiffener 409 and the second stiffener 410. This linkage mechanism is specifically designed for the lifting stage of the forging press. At this time, the mold and internal components are not subjected to compressive stress, which facilitates the controllable adjustment of the stiffener position through this transmission system. When the traction rod 301 moves along the negative z-axis, although the traction rod 301 and the fixed block 303 move down synchronously, the linkage between the transmission plate 305 and the stiffener assembly 4 is released, and the transmission chain is in a non-transmission state. Therefore, during the pressing process, the movement of the traction rod 301 will not drive the stiffener assembly 4, ensuring that the stiffener assembly remains fixed during the pressing stage of the forging press and does not affect the stability of the pressing process. It realizes the function of linkage adjustment when lifting and linkage separation when pressing, so that the stiffener adjustment operation can only be performed when the equipment is not under load, improving the adjustment accuracy and system reliability.

[0034] Please see Figure 5 In a preferred embodiment of this invention, the traction rod assembly 3 further includes a first inclined groove surface 304, a second inclined groove surface 306, a pin 307, a slide 308, and a rack 309. One end of the fixing block 303 is provided with the first inclined groove surface 304, and the transmission plate 305 is provided with the second inclined groove surface 306 facing the fixing block 303. The pin 307 is also rotatably mounted on the transmission plate 305. One end of the pin 307 is fixedly connected to the slide 308. The slide 308 is elastically slidably arranged in the base 101, and the other end of the transmission plate 305 is provided with a rack 309.

[0035] In practical application, the traction rod assembly 3 further integrates a first inclined groove surface 304, a second inclined groove surface 306, a pin 307, a slide 308, and a rack 309. The fixing block 303 has a first inclined groove surface 304 machined at its end, while the transmission plate 305 has a corresponding second inclined groove surface 306 on the side facing the fixing block 303. A pin 307 is mounted on the transmission plate 305 via a rotating pair. One end of the pin 307 is fixedly connected to the slide 308, which is elastically slidably disposed within the guide groove of the base 101, allowing it to reciprocate in a set direction within the groove. A rack 309 is also provided at the end of the transmission plate 305 away from the fixing block 303 for meshing with a subsequent transmission mechanism. When the fixed block 303 moves upward along the positive z-axis, the first inclined groove surface 304 at its end contacts the second inclined groove surface 306 on the transmission plate 305 and produces a pressing effect. Since the side of the transmission plate 305 is in surface contact with the base 101 at this time, a constraint condition is formed, preventing the transmission plate 305 from rotating clockwise around the pin 307. At this time, the interaction between the inclined groove surfaces converts the sliding contact force into a horizontal thrust, which pushes the transmission plate 305 to produce a translational motion along the positive x-axis. The translation of the transmission plate 305 further drives the slide table 308 to move synchronously in the groove of the base 101 through the pin 307. The slide table 308 needs to overcome the restoring force applied by the matching elastic element, thereby storing elastic potential energy.

[0036] The bottom of the fixed block is configured as a first plane a1, and the top surface of the transmission plate 305 is configured as a second plane a2. When the fixed block 303 descends along the negative z-axis, the first plane a1 at the bottom edge of the first inclined groove surface 304 and the second plane a2 at the top edge of the second inclined groove surface 306 first contact and press against each other. Since the transmission plate 305 is rotated and assembled through the pin 307, the direction of the contact force and the geometric conditions at this time allow the transmission plate 305 to rotate counterclockwise around the pin 307. This movement allows the transmission plate 305 to rotate and avoid the rib assembly 4 on one side without producing a substantial linkage effect. This allows the fixed block 303 to pass over the transmission plate 305 and descend to the initial position below the transmission plate 305. Then, under the action of gravity torque, the transmission plate 305 automatically rotates around the pin 307 back to the original horizontal posture to complete the reset. At the same time, the slide table 308 also returns to its original position along the slide under the action of the previously stored elastic restoring force, and the system returns to the initial ready state.

[0037] Please see Figure 6In a preferred embodiment of the present invention, the rib assembly 4 further includes a side rack 411, an adjusting gear 412, a worm gear 413, a worm 414, and a central gear 415. The side rack 411 is fixedly arranged on one side of the slide 402. One end of the adjusting gear 412 is meshed with the side rack 411, and the other end of the adjusting gear 412 is coaxially fixedly fitted with the worm gear 413. One end of the worm 414 is meshed with the worm gear 413, and the other end of the worm 414 is drivenly connected to the central gear 415. The central gear 415 and the rack 309 are movably connected.

[0038] In practical application, the side rack 411, adjusting gear 412, worm gear 413, worm 414, and central gear 415 together constitute a precise linkage adjustment mechanism. The side rack 411 is rigidly mounted on the lateral surface of the slide 402 and extends along the y-axis. The first side of the adjusting gear 412 maintains constant meshing with the side rack 411, while its second side is coaxially fixedly connected to the worm gear 413. One axial end of the worm 414 forms an orthogonal meshing transmission pair with the worm gear 413, and its other end is connected to the central gear 415 via a transmission connection component. The central gear 415 further connects with the longitudinally arranged... The rack 309 forms a movable connection. When the rack 309 connected to the transmission plate 305 makes a horizontal feed motion towards the first transmission slide 405 along the x-axis, the first transmission slide 405 transmits the motion to the worm wheel 413 while receiving the linear drive. The linear displacement of the first transmission slide 405 is converted into the rotational motion of the worm 414 through its internal transmission interface. The worm 414 then drives the worm wheel 413 meshing with it to produce an angular displacement. The rotation of the worm wheel 413 is amplified or converted by the coaxial adjusting gear 412 and accurately transmitted to the side rack 411, thereby pushing the carriage 402 to slide directionally along the bottom groove 401 preset at the bottom along the y-axis.

[0039] Since the first inclined slide 403 and the first transmission slide 405, as well as the second inclined slide 404 and the second transmission slide 406, are in contact through precision-machined inclined guide surfaces, when the carriage 402 drives the first inclined slide 403 and the second inclined slide 404 to move along the y-axis, the interaction of the inclined surfaces decomposes the y-axis displacement into a composite motion of the x-axis and z-axis. Specifically, under the constraint of the inclined surfaces, the first transmission slide 405 and the second transmission slide 406 respectively generate a displacement component in the z-axis direction, while the components fixed on the transmission slide... The first stiffener 409 and the second stiffener 410 move synchronously up and down in the z-axis direction. The magnitude of the displacement in the z-axis direction directly depends on the inclination angles α and β between the inclined guide surface and the horizontal reference surface. According to the geometric motion relationship, by precisely designing the values ​​of inclination angles α and β, independent control and optimized matching of the movement stroke of the first stiffener 409 and the second stiffener 410 in the z-axis direction can be achieved, thereby completing the spatial coordinated motion of complex trajectories. It can adapt to stiffener structures of different lengths and enable several stiffeners to reach the ejection state simultaneously before forging is completed.

[0040] Furthermore, a reliable self-locking mechanism is formed between the worm gear 413 and the worm 414 through a specific helix angle design. This structure can automatically lock when a reverse driving force is generated during the forging process, effectively preventing any axial or circumferential slippage of the transmission system when subjected to high load impact, ensuring the absolute stability of power transmission and operational safety. The force direction of the slide 402 can be decomposed into two components along the y-axis and z-axis. When the y-axis movement is constrained, the y-direction load borne by the slide 402 will be directly transmitted and act on the structure of the bottom slide groove 401.

[0041] Furthermore, the slide 402 ensures that the forging process is completed before reaching the dead point position, and then rotates in the opposite direction by means of an external power source, including manual operation or electric drive, to drive the slide 402 to return to its initial ready position.

[0042] Please see Figure 3 In a preferred embodiment of the present invention, the traction assembly 5 includes a cylindrical base 501, a central hole 502, a claw plate 503, a traction claw 504, a reset surface 505, a bayonet 506, and a reset post 507. The cylindrical base 501 is fixedly assembled to the bottom of the moving template 106. The central hole 502 is also provided in the middle of the cylindrical base 501. One end of the claw plate 503 is fixedly connected to the cylindrical base 501. The claw plate 503 is also elastically rotatably mounted with a plurality of traction claws 504 in the circumferential direction. The top of the traction claw 504 is provided with a reset surface 505, and the bottom of the traction claw 504 is provided with a bayonet 506. The reset post 507 is fixedly installed on the top plate 104 and is concentrically arranged with the cylindrical base 501.

[0043] In practical application, the cylindrical base 501 is fixedly assembled on the bottom structure of the moving template 106. A through-axial central hole 502 is machined at the geometric center. One end of the claw plate 503 is rigidly connected to the cylindrical base 501. Multiple elastically rotatable traction claws 504 are distributed along its circumference. The top area of ​​each traction claw 504 is designed with an inclined reset surface 505, and the bottom is provided with a locking slot 506. The reset column 507, coaxially arranged with the cylindrical base 501, is fixedly installed below the top plate 104. When the hydraulic press 105 drives the moving template 106 and the cylindrical base 501 fixed thereon towards the mold base 102 along the negative z-axis... During movement, several traction claws 504 distributed on the claw plate 503 simultaneously contact and press against the conical surface of the cone head 302. During the continuous downward movement, the traction claws 504 slide along the conical surface and generate radial elastic opening until the latch 506 passes the bottom edge of the cone head 302. Under the action of elastic restoring force, they radially close, so that the latch 506 and the bottom of the cone head 302 form a locking connection. Subsequently, when the moving template 106 is driven by the hydraulic press 105 to return along the positive z-axis, since the latch 506 has been locked at the bottom of the cone head 302, the traction claws 504 will drive the traction rod 301 to move synchronously along the positive z-axis, thereby realizing the lifting operation of the rod.

[0044] Before the moving template 106 moves upward and approaches its upper limit position, the reset column 507 fixed to the top plate 104 passes through the central hole 502 of the cylinder seat 501 and gradually presses against the reset surface 505 of each traction claw 504. The reset column 507 continuously presses down on the reset surface 505, forcing each traction claw 504 to overcome its own elastic torque and rotate, causing the bayonet 506 to generate radial displacement, thereby disengaging from the bottom of the cone head 302. Once the lock is released, the traction rod 301 automatically and quickly resets along the negative z-axis under the action of the elastic reset mechanism set at its lower end, returning to the initial ready position, preparing for the subsequent work cycle. Throughout the process, the coordinated action of the cylinder seat 501, the traction claw 504 and the reset column 507 realizes the controllable lifting and automatic release reset of the traction rod 301 within the preset stroke.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
