Description

Technical Field

[0001] The present invention relates to the technical field of steel structure production, and in particular to a forging device based on H-shaped steel structure production. Background Art

[0002] As a structural form widely used in various building fields, H-shaped steel structures are favored for their unique advantages. It is mainly composed of key components such as steel beams and steel columns, and is named after its cross-section being in the shape of an "H". The reasonable cross-sectional shape of H-shaped steel gives full play to the mechanical properties of steel, endowing it with excellent load-bearing capacity and bending resistance. Compared with traditional concrete structures, the remarkable feature of H-shaped steel structures is their light self-weight, which not only greatly reduces the overall weight of buildings, but also effectively reduces the construction cost of foundation projects. During the construction process, the degree of component factory production is high, and on-site installation is simple and efficient, which can greatly shorten the construction period. At the same time, H-shaped steel structures have good seismic resistance. In the face of natural disasters such as earthquakes, they can ensure the structural stability of buildings and provide reliable support for life and property safety. In addition, they have high space utilization rate and can flexibly plan the internal space according to the building function requirements, and are widely used in many engineering scenarios such as industrial factories, high-rise buildings, and bridges.

[0003] In the production and processing of H-shaped steel structures, die forging is a commonly used process. For example, a forging machine for H-shaped steel structure production disclosed in a Chinese patent with the publication number of "CN215544609U" includes components such as a workbench, a forging device, a loading and unloading device, an electric ejector rod, a discharge pipe, and a purification device. An installation frame is provided on the workbench, the forging device is installed on the upper part of the installation frame, and the loading and unloading device is located at the lower part of the installation frame. With the help of a slide rail, a moving machine, side clamping plates, clamping plates, and an electric telescopic rod, the moving machine can move on the slide rail. The steel materials that have been calcined on the placement table are fixed between the side clamping plates by driving the clamping plates to act through the electric telescopic rod, and then sent into the die for forging. After forging is completed, the electric ejector rod ejects the steel from the die, the clamping plates clamp and retract, and then the moving machine transports the steel to the upper part of the discharge pipe for dropping and collection, realizing automatic loading and unloading and automatic ejection of steel, and improving the forging efficiency to a certain extent.

[0004] However, after in-depth analysis of the actual application of the device, it is found that there are many drawbacks in the production and processing process. This device relies on multiple electric jacks and electric push rods to work together, and numerous electronic components are required to assist in the feeding and processing links, resulting in extremely complex wiring arrangements. The complex wiring not only makes the subsequent maintenance work extremely difficult, but also integrating multiple electric push rods and electric jacks significantly increases the design cost. The power consumption during the operation of the device cannot be underestimated. Excessive electrical appliances for production lead to high overall usage costs. At the same time, due to the need for frequent maintenance of electronic components, and in the long-term use of electronic components, the internal circuit system is prone to damage, seriously affecting the stability of the device operation. In summary, the existing H-shaped steel structure production and processing equipment has obvious deficiencies in cost control and stability, and urgently needs to be improved and designed to meet the requirements of efficient, low-cost, and stable production. Summary of the Invention

[0005] The purpose of the present invention is to provide a forging device based on the production of H-shaped steel structures to solve the problems of high overall usage cost and inconvenient subsequent maintenance caused by the need for multiple electric push rods to assist in the feeding and positioning during the application of the existing technology as mentioned in the above background technology.

[0012] Further, the linkage mechanism further includes a bottom frame fixedly installed at the bottom of the guiding plate.

[0013] Further, the pusher mechanism includes a rail frame and a pusher connecting arm. The pusher connecting arm is fixedly connected to the side of the connecting disk away from the linkage connecting arm.

[0014] Further, a placing plate is fixedly installed in the middle at the rear side of the top of the pedestal. A plurality of balls are rotatably connected to the top of the placing plate at equal intervals.

[0015] Further, a discharge guide plate is fixedly installed in the middle at the front side of the pedestal. A collecting material box is slidably connected to the top of the base. The discharge guide plate is arranged directly above the collecting material box.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting the positioning and guiding mechanism in the present invention, during use, the steel to be forged can be pushed by the pusher mechanism to the top of the lower template. The hydraulic cylinder is started, and it pushes the upper template and the lower template to close the mold to achieve rapid forging and forming. During the forging process, the hydraulic cylinder drives the connecting disk to move downward, successively linking the connecting arm, the inner guiding plate of the supporting rail, the rack, and the gear, and then causing the screw rod in the guide rail to rotate. Since the thread directions at both ends of the screw rod are opposite, the two sliders can be synchronously driven to slide, driving the adjusting assembly to push the elastic guiding assembly inward, making the guiding rollers 357 fit on both sides of the steel, quickly centering and pushing the steel. During the inward movement, the telescopic spring buffers, providing space for the downward pressure of the hydraulic cylinder, ensuring stable stamping, and the position of the sliding plate on the adjusting rail can also be adjusted according to the size of the steel to adapt to different steels. This process does not require additional electronic components, significantly improving the forging stability and reducing costs; When the equipment is running, each time the hydraulic cylinder is started, its operation drives the connecting disk to move downward, and then pushes the pusher connecting arm and the upper guide frame to move downward. The inclined surface of the upper guide frame contacts the inclined surface of the lower guide frame, and through the linkage of the guiding rollers 357, the longitudinal thrust is converted into a lateral thrust, pushing the lower guide frame to assist the sliding block in the rail frame to slide, compressing the return spring, driving the pusher plate to move backward to the rear side of the placing plate. At this time, the steel to be die-forged can be placed. When the hydraulic cylinder moves upward, the pusher connecting arm moves upward to reset the upper guide frame, and the return spring pushes the sliding block to move forward, driving the pusher plate to push the steel on the placing plate to the top of the lower template. The balls on the placing plate reduce the friction, and the high-elasticity return spring ensures the stable pushing of the steel. The entire feeding process only relies on the power of the hydraulic cylinder and does not require additional electronic components, which is efficient and convenient; During the operation of this equipment, when the hydraulic cylinder drives the upper mold to reset, the push-pull chassis at the bottom of the hydraulic cylinder moves up and down. When moving up and resetting, it drives the chassis to push the demoulding substrate upward. The demoulding substrate drives the demoulding ejector rod to push out the steel in the lower template for demoulding. At the same time, the reset spring resets and pushes the steel to be forged forward, squeezing the formed steel so that it falls into the discharge guide plate and automatically falls into the collection bin through the guidance of the discharge guide plate. From the demoulding of the steel to the collection, the whole process only relies on the power of the hydraulic cylinder to achieve automatic blanking. This ingenious design avoids the use of additional electronic components, not only reducing the energy consumption of the equipment, but also improving the stability of production and processing, effectively reducing the overall cost, and demonstrating the high efficiency and economy of the equipment.

Detailed Embodiment

[0019] Please refer to Figures 1-8 , in the embodiment of the present invention, a forging device based on the production of H-shaped steel structures includes a base 1. Support legs 2 are fixedly installed at the four corners of the top of the base 1. A pedestal 10 is fixedly installed at the top of the support legs 2. A frame 4 is fixedly installed at the top of the pedestal 10. A hydraulic cylinder 5 is fixedly installed at the top of the frame 4. The output end of the hydraulic cylinder 5 penetrates through the frame 4 and is fixedly installed with a connecting plate 6. An upper template 7 is fixedly installed at the bottom of the connecting plate 6. A pushing mechanism 8 is arranged on one side of the frame 4. A linkage mechanism 9 is fixedly installed on the side of the frame 4 away from the pushing mechanism 8. A positioning and guiding mechanism 3 is fixedly installed in the middle of the pedestal 10. The positioning and guiding mechanism 3 is linked with the linkage mechanism 9. A bench 11 is fixedly installed at the top of the pedestal 10 outside the positioning and guiding mechanism 3. A lower template 12 is fixedly installed at the top of the bench 11. One side of the connecting plate 6 is connected to the linkage mechanism 9, and the other side of the connecting plate 6 is connected to the pushing mechanism 8; The positioning and guiding mechanism 3 includes a guide rail 31 which is fixedly installed in the middle of the pedestal 10. A lead screw 32 is rotatably connected inside the guide rail 31. Both ends of the outer surface of the lead screw 32 are threadedly connected with sliders 33. The thread directions at both ends of the lead screw 32 are opposite. A regulating component 34 is fixedly installed on the top of the slider 33. An elastic guiding component 35 is installed inside the regulating component 34. One end of the lead screw 32 close to the linkage mechanism 9 penetrates through the guide rail 31 and is fixedly connected with a gear 36. The gear 36 is in transmission connection with the linkage mechanism 9. In the forging equipment, the base 1 firmly supports the pedestal 10 through the support legs 2 at the four corners of the top, providing a solid support for the whole equipment. When the equipment is started, the hydraulic cylinder 5 at the top of the frame 4 starts to work, and its output end pushes the connecting plate 6 downward. The connecting plate 6 then drives the upper template 7 fixed thereto to move downward, and is clamped with the lower template 12 at the top of the table frame 11 to realize the forging operation of the H-shaped steel. The feeding mechanism 8 is located on one side of the frame 4. During the downward movement of the connecting plate 6, it will drive the feeding mechanism 8 to operate, and push the steel to be forged placed at a specific position along a set path above the lower template 12, accurately preparing the raw materials for the forging process. On the other side of the frame 4 far from the feeding mechanism 8, the linkage mechanism 9 is fixedly installed. One side of the connecting plate 6 is connected to the linkage mechanism 9. When the connecting plate 6 moves with the hydraulic cylinder 5, it will drive the linkage mechanism 9 to operate. The linkage mechanism 9 then drives the gear 36 in the positioning and guiding mechanism 3 to rotate. The gear 36 is fixedly connected with the lead screw 32. Therefore, the rotation of the gear 36 will cause the lead screw 32 to rotate inside the guide rail 31. Since the thread directions at both ends of the lead screw 32 are opposite, when the lead screw 32 rotates, the sliders 33 threadedly connected to both ends of the outer surface will slide in opposite directions inside the guide rail 31. The regulating component 34 fixed to the top of the slider 33 will move along with the sliding of the slider 33, and the elastic guiding component 35 installed inside the regulating component 34 will also act accordingly, and can be adaptively adjusted according to the specific size of the H-shaped steel, positioning and clamping the steel from both sides to ensure that the steel is always in the accurate position during the forging process, guaranteeing the precision and quality of forging. Each mechanism cooperates with each other to complete the forging production of the H-shaped steel structure.

[0020] Please refer to Figures 6-8, the adjusting assembly 34 includes an adjusting rail 341. The adjusting rail 341 is fixedly installed on the top of the slider 33. A slide plate 342 is slidably connected inside the adjusting rail 341. The inner end of the slide plate 342 is connected to the elastic guiding assembly 35. The outer end of the top of the slide plate 342 is fixedly installed with a fixed frame 343. Hand-tightening screws 344 are threadedly connected to both sides of the fixed frame 343. The end of the hand-tightening screw 344 penetrates through the fixed frame 343. Equal-spacing limiting holes 345 are provided on both sides of the adjusting rail 341. The end of the hand-tightening screw 344 penetrates through the fixed frame 343 and is inserted into the limiting hole 345 inside. The cross-sectional shapes of the inner cavity of the slide plate 342 and the adjusting rail 341 are both set to a convex shape. The elastic guiding assembly 35 includes side plates 351. The side plates 351 are fixedly installed at the inner end of the slide plate 342. Fixed frames 352 are fixedly installed at both ends of the side plates 351. Two telescopic springs 353 are fixedly installed inside each of the fixed frames 352. The end of the telescopic spring 353 is fixedly installed with a movable block 354. A guiding frame 355 is fixedly installed on the inner side of the movable block 354. A supporting fixed shaft body 356 is fixedly installed on the outer side of the movable block 354. The end of the supporting fixed shaft body 356 penetrates through the fixed frame 352. The supporting fixed shaft body 356 is slidably connected to the fixed frame 352. Guiding rollers 357 are rotatably connected at equal intervals on the inner side of the guiding frame 355. The adjusting assembly 34 and the elastic guiding assembly 35 cooperate to realize the flexible positioning and buffer clamping of the H-shaped steel. The adjusting rail 341 is fixed on the top of the slider 33, and the inner slide plate 342 can slide inside it. Since the cross-section of the inner cavity of the slide plate 342 and the adjusting rail 341 is convex, it can effectively prevent the slide plate 342 from coming out. When it is necessary to adjust the position of the elastic guiding assembly 35 to adapt to H-shaped steels of different sizes, loosen the hand-tightening screws 344 threadedly connected to both sides of the fixed frame 343, so that the end of the screw disengages from the limiting holes 345 on both sides of the adjusting rail 341, and then the slide plate 342 can be pushed to slide inside the adjusting rail 341. After adjusting to the appropriate position, tighten the hand-tightening screws 344 again, so that their ends are inserted into the corresponding limiting holes 345 to fix the slide plate 342. The side plates 351 of the elastic guiding assembly 35 are installed at the inner end of the slide plate 342. Telescopic springs 353 are provided inside the fixed frames 352 at both ends of the side plates 351. The ends of the springs are connected to the movable blocks 354. Guiding rollers 357 are evenly rotatably connected to the guiding frame 355 on the inner side of the movable blocks 354, and the outer sides are connected to the supporting fixed shaft bodies 356. The supporting fixed shaft bodies 356 can slide inside the fixed frames 352. When positioning the H-shaped steel, the guiding rollers 357 contact the surface of the steel. The position deviation of the steel or the displacement during forging will cause the guiding frame 355 to push the movable block 354 to squeeze the telescopic spring 353. The telescopic spring 353 provides a buffering force, which not only ensures that the guiding frame 355 closely fits the steel, but also avoids damaging the steel due to rigid contact, realizing the precise positioning and flexible clamping of the H-shaped steel.

[0021] Please refer to Figures 1-7, the linkage mechanism 9 includes a linkage connecting arm 91 and a support and fixing rail 92. The linkage connecting arm 91 is fixedly installed on the side of the connecting disk 6 away from the material pushing mechanism 8. A guiding plate 93 is fixedly installed at the outer end of the bottom of the linkage connecting arm 91. The support and fixing rail 92 is fixedly connected to the side of the pedestal 10 away from the material pushing mechanism 8. The guiding plate 93 is slidably connected to the inside of the support and fixing rail 92. A rack 94 is fixedly installed on the side of the guiding plate 93 close to the gear 36. The rack 94 is meshed with the gear 36. The linkage mechanism 9 further includes a chassis 95. The chassis 95 is fixedly installed at the bottom of the guiding plate 93. A demolding substrate 96 is fixedly installed on the side of the chassis 95 close to the pedestal 10. Demolding ejector rods 97 are fixedly installed at the four corners of the top of the demolding substrate 96. The top of the demolding ejector rod 97 penetrates through the lower template 12. The demolding ejector rod 97 is slidably connected to the lower template 12. The linkage mechanism 9 works in coordination through multiple components and plays a key role during the operation of the equipment. When the connecting disk 6 moves downward, it drives the linkage connecting arm 91 fixed on one side of it to move downward synchronously. The guiding plate 93 at the outer end of the bottom of the linkage connecting arm 91 slides inside the support and fixing rail 92 accordingly. The rack 94 fixed on one side of the guiding plate 93 meshes with the gear 36 in the positioning and guiding mechanism 3. The downward movement of the guiding plate 93 drives the rack 94 to move downward, thereby causing the gear 36 to rotate, driving the lead screw 32 to rotate, and realizing the linkage control of the slider 33, the adjustment assembly 34, and the elastic guiding assembly 35, completing the positioning and clamping adjustment of the H-shaped steel. At the same time, the chassis 95 fixed to the bottom of the guiding plate 93 also moves downward. When the hydraulic cylinder 5 drives the connecting disk 6 to move upward and reset after forging, the chassis 95 moves upward, pushing the demolding substrate 96 upward. The demolding ejector rods 97 at the four corners of the top of the demolding substrate 96 are pushed upward accordingly, penetrate through the lower template 12, and push out the H-shaped steel formed inside the lower template 12 for demolding. The entire linkage process is closely coordinated to ensure the efficient operation of the equipment.

[0022] Please refer to Figures 1-6, the material pushing mechanism 8 includes a rail frame 81 and a material pushing connecting arm 82. The material pushing connecting arm 82 is fixedly connected to the side of the connecting disk 6 away from the linkage connecting arm 91. The rail frame 81 is fixedly installed on the side of the frame 4 away from the linkage mechanism 9. A return spring 83 is fixedly installed at the inner rear end of the rail frame 81. The end of the return spring 83 is fixedly connected to a sliding block 84. An upper guide frame 85 is fixedly installed on the top of the sliding block 84. The outer end of the material pushing connecting arm 82 is fixedly connected to an upper guide frame 86. The inner sides of the upper guide frame 86 and the lower guide frame 85 are both provided with inclined surfaces, and the inclined surfaces of the upper guide frame 86 and the lower guide frame 85 are mutually attached and connected. The upper guide frame 86 and the lower guide frame 85 are both set as right-angled triangles. A connecting frame 812 is fixedly installed at the rear side of the sliding block 84. A material pushing plate 87 is fixedly installed at the rear end of the connecting frame 812. A placement plate 88 is fixedly installed in the middle of the rear side of the top of the pedestal 10. A plurality of balls 89 are rotatably connected at equal intervals on the top of the placement plate 88. A discharge guide plate 810 is fixedly installed in the middle of the front side of the pedestal 10. A collection material box 811 is slidably connected to the top of the base 1. The discharge guide plate 810 is arranged directly above the collection material box 811. The material pushing mechanism 8 orderly completes the steel material loading and finished product discharging work during the operation of the equipment. When the hydraulic cylinder 5 is started, the connecting disk 6 drives the material pushing connecting arm 82 to move downward, and the upper guide frame 86 fixed to the outer end of the material pushing connecting arm 82 moves downward synchronously. Since the inner inclined surfaces of the upper guide frame 86 and the lower guide frame 85 are mutually attached, and both of them are right-angled triangle structures, when the upper guide frame 86 moves downward, its inclined surface pushes the lower guide frame 85 to move horizontally in the rail frame 81. The lower guide frame 85 is fixed to the top of the sliding block 84, which causes the sliding block 84 to compress the return spring 83 at the inner rear end of the rail frame 81 and slide backward. At the same time, the material pushing plate 87 on the connecting frame 812 at the rear side of the sliding block 84 also moves to the rear side of the placement plate 88. At this time, the steel material to be forged is placed on the placement plate 88 provided with balls 89 to reduce the friction force. When the hydraulic cylinder 5 drives the connecting disk 6 to move upward, the material pushing connecting arm 82 drives the upper guide frame 86 to reset, and the return spring 83 pushes the sliding block 84, the connecting frame 812, and the material pushing plate 87 to move forward. The material pushing plate 87 pushes the steel material on the placement plate 88 to slide onto the top of the lower die plate 12 on the front side of the pedestal 10. After the steel material is forged, as the subsequent steel material to be forged is pushed forward, the formed steel material is extruded, guided by the discharge guide plate 810, and falls into the collection material box 811 on the top of the base 1, realizing an automatic and efficient material pushing and collection process.

[0023] The working principle of the present invention is as follows: In the present invention, the ingenious design of the positioning and guiding mechanism 3 greatly improves the operation efficiency and stability of the equipment. When performing the forging operation of the H-shaped steel structure, the steel material to be forged is pushed to the top of the lower die plate 12 by the material pushing mechanism 8. At this time, the hydraulic cylinder 5 is started, and the powerful thrust generated by the hydraulic cylinder 5 drives the upper die plate 7 to move downward smoothly and accurately close the die with the lower die plate 12, thereby realizing an efficient forging and forming process.

[0024] During the forging process, as the hydraulic cylinder 5 pushes the connecting plate 6 downward, the connecting plate 6 synchronously drives the linkage connecting arm 91 to move downward. The downward movement of the linkage connecting arm 91 further pushes the guide plate 93 in the support and fixing rail 92 downward. The displacement of the guide plate 93 causes the rack 94 to move downward accordingly. Since the rack 94 is in meshing with the gear 36, the downward movement of the rack 94 drives the gear 36 to rotate. The rotation of the gear 36 then drives the lead screw 32 in the guide rail 31 to rotate synchronously. It should be noted that the thread directions at both ends of the lead screw 32 are opposite. This special design enables the gear 36 to drive the lead screw 32 to rotate, and at the same time, it can synchronously drive the two sliders 33 to slide in the opposite directions within the guide rail 31. The sliding of the sliders 33 drives the adjustment assembly 34 at their tops to act. The adjustment assembly 34 pushes the elastic guiding assembly 35 to move inward. Further, the side plate 351 drives the guiding frame 355 to move inward synchronously, so that the guiding rollers 357 closely fit on both sides of the steel to be processed. Through the synchronous drive of the lead screw 32 on the sliders 33, the steel can be quickly and accurately pushed towards the central position. During the inward movement of the steel, the telescopic spring 353 plays a key buffering role, providing the necessary moving space for the continuous downward pressure of the hydraulic cylinder 5. The flexible connection design of the telescopic spring 353 ensures that while the hydraulic cylinder 5 is stably stamping, it can synchronously drive the two guiding frames 355 to move inward, accurately centering and guiding the steel to be forged, significantly improving the stability of the equipment during the forging process.

[0025] In addition, during the forging process, according to the specific forging requirements, the sliding position of the sliding plate 342 in the adjustment rail 341 can be flexibly adjusted to adjust the extension length of the elastic guiding assembly 35, so as to achieve the adaptation to steel to be forged with different sizes. After the adjustment is completed, just turn the hand-twist screw 344 and insert it into the installation and fixing frame 343 in the limit hole 345, then the sliding plate 342 can be firmly fixed to ensure that the sliding plate 342 is stably installed in the adjustment rail 341. It can be seen that in the die forging process of this device, the power of the hydraulic cylinder 5 to push the upper template 7 and the lower template 12 to close the die is cleverly utilized to drive the positioning and guiding mechanism 3 to complete the clamping and positioning of the steel, without the need to additionally configure electronic components. This innovative design not only realizes fast and stable die forging production, but also avoids the subsequent maintenance work on the loss of additional circuit systems and electronic components, effectively reducing the upfront use cost and the later maintenance cost.

[0026] The pusher mechanism 8 in the present invention also demonstrates excellent innovation and practicality. During the operation and processing of the equipment, first, the hydraulic cylinder 5 is started. During the operation of the hydraulic cylinder 5, the connecting plate 6 is driven to move downward. The downward movement of the connecting plate 6 pushes the pusher connecting arm 82 to move downward synchronously. The downward movement of the pusher connecting arm 82 further causes the upper guide frame 86 to move downward. During the downward movement of the upper guide frame 86, the inclined surface of the upper guide frame 86 comes into contact with the inclined surface of the lower guide frame 85 and generates a guiding effect. Through the linkage of the inclined surface and the guiding roller 357, the longitudinal thrust is cleverly converted into a lateral thrust, thereby pushing the lower guide frame 85 to assist the sliding block 84 to slide within the rail frame 81. While the lower guide frame 85 pushes the sliding block 84 to slide, the return spring 83 is compressed and in a contracted state. The movement of the sliding block 84 drives the connecting frame 812 at its rear side. The movement of the connecting frame 812 ultimately drives the pusher plate 87 to move backward to the rear side of the placement plate 88. At this time, the steel to be die-forged can be placed on the top of the placement table.

[0027] After the placement is completed, the hydraulic cylinder 5 is started to move upward. The upward movement of the hydraulic cylinder 5 drives the pusher connecting arm 82 to move upward. The upward movement of the pusher connecting arm 82 causes the upper guide frame 86 to reset. After the upper guide frame 86 resets, the return spring 83 loses the compressive force and quickly resets. The reset of the return spring 83 pushes the sliding block 84 to move forward. The forward movement of the sliding block 84 drives the connecting frame 812, and then drives the pusher plate 87 to move forward. The forward movement of the pusher plate 87 pushes the steel to be forged on the placement plate 88 to slide from the placement plate 88 to the top of the lower template 12. The balls 89 on the placement plate 88 effectively reduce the friction when the steel moves, making the pusher process smoother. At the same time, the return spring 83 uses a high-elasticity spring, which can ensure that the steel to be forged is stably pushed to the top of the lower template 12. At this time, starting the hydraulic cylinder 5 to operate again can push the upper die and the lower template 12 to be die-forged. After the hydraulic cylinder 5 moves downward, at this time the pusher plate 87 moves to the rear side of the placement plate 88 again. At this time, only the steel to be processed needs to be placed on the top of the placement plate 88, so that the equipment only needs to start the hydraulic cylinder 5 to reciprocate telescopically to perform automatic auxiliary feeding.

[0028] It is worth mentioning that when the hydraulic cylinder 5 drives the upper mold to reset, the bottom of the hydraulic cylinder 5 will correspondingly push and pull the chassis 95 to move up and down. When the hydraulic cylinder 5 moves upward to reset, it drives the chassis 95 to push the demoulding substrate 96 upward. The demoulding substrate 96 then drives the demoulding ejector rod 97 to push out the steel in the lower template 12 for demoulding. After the steel is demoulded, due to the reset spring 83 resetting to push the steel to be forged forward, the formed steel is extruded and falls into the discharge guide plate 810, and through the guiding action of the discharge guide plate 810, it automatically falls into the collection bin 811. It can be seen that through the ingenious linkage structure design of this device, relying only on the power of the hydraulic cylinder 5, a series of processes such as clamping and positioning, automatic feeding and demoulding can be completed without the need to rely on additional electronic components. This design greatly reduces the cost of using electronic components during the operation of the equipment, reduces the energy consumption of the equipment, and effectively reduces the overall cost while improving the stability of production and processing.
