Description

Technical Field

[0001] This invention relates to the field of metal forging, specifically to an automatic feeding forging machine. Background Technology

[0002] Forging is a crucial method for forming and processing metal parts. It involves applying pressure to cause plastic deformation in heated metal billets, thereby obtaining forgings with the desired shape and properties. Traditional forging production lines typically rely on manual operation or simple conveyor systems to transport and position the heated billets at the forging station. This method is not only inefficient and poses significant safety hazards, but also results in high labor intensity for workers, making it difficult to meet the demands of modern, automated, and continuous production.

[0003] To improve the automation level of forging production, some automatic feeding devices have emerged in existing technologies. For example, tilting platforms combined with pushing mechanisms are used to achieve initial movement of the billet; heating stations are set up to heat the billet online; heated billets are transported by gravity using chutes or guide rails; and the billets are transferred to the forging die using robotic arms or clamping mechanisms. These technical solutions reduce manual intervention to a certain extent and form part of the foundation for automated forging production lines.

[0004] However, existing automated feeding technologies still have significant drawbacks. First, the material transfer path between stations is usually fixed and lacks flexibility, making it difficult to adapt to complex or changing process requirements. Second, when materials are transferred from the conveyor line to the clamping or forging station, there is often a risk of misalignment, jamming, or falling, affecting production cycle time and reliability. Furthermore, the existing clamping and placement mechanisms suffer from insufficient structural complexity and coordination, potentially leading to inaccurate material placement and consequently affecting subsequent forging quality. Therefore, there is an urgent need for a more rationally designed, precise, reliable, and highly automated automated feeding forging equipment to overcome these shortcomings. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an automatic feeding forging machine to solve the technical problems of fixed material transfer path, low alignment accuracy between workstations, and complex structure and insufficient reliability of clamping and placement mechanism in existing forging equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic feeding forging machine, characterized in that it comprises: a placement platform for stacking materials to be processed; a dropping platform connected to the discharge side of the placement platform for receiving and guiding the materials to fall; a heating platform connected to the discharge side of the dropping platform for heating the materials; a pushing platform connected to the discharge side of the heating platform for receiving the heated materials and pushing them out; a chute disposed on the discharge side of the pushing platform for receiving the pushed materials and guiding them to slide; a variable-track chute movably connected to the end of the chute for changing the sliding path of the materials; a clamping structure disposed on one side of the variable-track chute for clamping the materials falling from the variable-track chute; a support platform disposed below the clamping structure for supporting the materials placed by the clamping structure; and a forging die disposed on the front side of the support platform for forging the materials on the support platform.

[0007] The present invention is further configured such that anti-fall railings are provided on both sides of the falling platform, and anti-fall plates are provided on the pushing platform.

[0008] The present invention is further configured such that a heating plate is provided on one side of the heating platform, and a first push rod for pushing the material toward the chute is provided on the inner side of the pushing platform.

[0009] The invention is further configured such that a second push rod for driving the sliding groove to move and align with the position of the clamping structure is connected to one side of the sliding groove, and the second push rod is connected to a second push motor.

[0010] The present invention is further configured such that the clamping structure is provided with a spring and a clamping plate inside, for realizing elastic clamping and release of materials.

[0011] The invention is further configured such that the clamping structure is connected to a rotating wheel, the rotating wheel is connected to a rotating motor via a rotating shaft, and the rotating motor drives the rotating wheel to rotate, thereby transferring the material from the side of the variable track chute to the top of the support platform.

[0012] The present invention is further configured such that a first push motor is provided on the rear side of the bearing platform, and the first push motor is connected to a first push rod for pushing the forged material out of the bearing platform.

[0013] The present invention is further configured such that a second push rod is connected to the rear end of the forging die, and a forging machine is connected to the rear end of the second push rod. The forging machine drives the forging die to forge the material on the bearing platform through the second push rod.

[0014] In summary, the present invention has the following main beneficial effects:

[0015] This invention achieves flexible adjustment of material transfer paths and precise alignment between workstations by combining a movable variable-track slide with a precisely controlled clamping structure. The clamping structure adopts an elastic clamping design, which simplifies the mechanism and improves clamping reliability. Combined with an anti-drop device and an automated push component, the overall system has a high degree of integration, effectively overcoming the defects of fixed transfer paths, low alignment accuracy, and complex and unreliable clamping mechanisms in existing technologies, thereby improving the automation, efficiency, and stability of forging production.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] As attached Figures 1 to 5 As shown, an embodiment of the present invention provides an automatic feeding forging machine.

[0024] The automatic feeding forging machine is arranged sequentially along the material processing direction to form a continuous automated processing line. Its core architecture mainly includes a placement platform 1 for initial material stacking, a falling platform 2 for guiding the material to fall faster, a heating platform 16 for online heating of the material, a pushing platform 4 for receiving and transferring the heated material, a chute 6 for guiding the material to slide down, a track-changing chute 13 for changing the material's downward path, a clamping structure 12 for grabbing and transferring the material, a support platform 19 for carrying the material for forging, and a forging die 18 for finally performing the forging process.

[0025] Specifically, the placement platform 1 is typically designed as a horizontal platform or a platform with a slight inclination angle. Its surface may be provided with anti-slip textures or guardrails to facilitate operators in placing the metal billets to be processed in a concentrated manner. The discharge side of the placement platform 1 is fixedly connected to the higher end of the falling platform 2, with a smooth transition between the two, ensuring that the material can smoothly enter the next stage by gravity or slight external force.

[0026] The dropping platform 2 is designed as a plate-like structure with a large inclination angle, with long strip-shaped anti-fall rails 17 bent vertically upwards or welded to its two side edges. These two anti-fall rails 17 are arranged in parallel, forming an open guide channel, the width of which is slightly larger than the width of the material. After the material slides into this channel from the placement platform 1, it accelerates down the inclined surface under the action of gravity. The function of the anti-fall rails 17 is to prevent the material from falling out from the sides during the high-speed descent, ensuring the stability of the movement trajectory.

[0027] The discharge side of the falling platform 2, i.e., the lower end of its inclined surface, smoothly connects to the upstream end of the heating platform 16. The heating platform 16 is also designed as an inclined structure, but its inclination angle may be smaller than that of the falling platform 2 to control the material's downward sliding speed and extend the heating time. A heating plate 3 is fixedly installed on one side of the heating platform 16. This heating plate 3 can be a conventional heating element in the art, such as a resistance heating plate, a gas heating plate, or an induction heating coil. The position and power of the heating plate 3 are designed to uniformly and rapidly heat the material sliding across its surface, ensuring that it reaches the required forging temperature by the time it reaches the end of the heating platform 16.

[0028] The discharge side of the heating platform 16 is fixedly connected to the pushing platform 4. The pushing platform 4 is roughly a horizontal platform surface used to temporarily store the heated material. An upwardly protruding anti-fall plate 23 is provided on its edge near the heating platform 16. This anti-fall plate 23 effectively blocks material that has been propelled out of the heating platform 16 due to inertia, ensuring it accurately stops at a predetermined position on the pushing platform 4. A first push rod 5 is installed below the platform surface or in the side frame of the pushing platform 4. The first push rod 5 can be a cylinder, hydraulic cylinder, or electric linear module. The extension and retraction direction of its piston rod or push head is horizontal and consistent with the direction in which the material needs to be pushed. When the sensor detects that the material is in place on the pushing platform 4, the first push rod 5 is activated, and its push head moves forward, pushing the material horizontally and smoothly towards the discharge side edge of the pushing platform 4.

[0029] Below the discharge edge of the pushing platform 4, the chute 6 is inclinedly installed. The higher end opening of the chute 6 faces the discharge edge of the pushing platform 4 and is used to receive the material pushed out by the first push rod 5. After the material falls into the chute 6, it accelerates down its smooth inner slope under the action of gravity. The inclination angle and length of the chute 6 can be designed according to the weight of the material and the process cycle requirements.

[0030] The end of the slide 6, i.e., its lower outlet, is movably connected to the variable track slide 13. The variable track slide 13 itself is also in the shape of an inclined channel, and its inlet end is mounted on the frame through a sliding pair or hinge mechanism, allowing the entire variable track slide 13 to move horizontally or along a specific trajectory. The specific drive mechanism is as follows: a second push rod 14 is connected to one side of the variable track slide 13, and the tail end of the second push rod 14 is connected to the output shaft of the second push motor 15 through a transmission mechanism such as a ball screw. When the second push motor 15 starts, it drives the second push rod 14 to perform linear extension and retraction, thereby causing the variable track slide 13 to move laterally as a whole. By controlling the rotation angle of the second push motor 15, the outlet end of the variable track slide 13 can be precisely aligned with different workstations; for example, one workstation is the receiving position of the clamping structure 12, and another workstation can be a maintenance passage or an emergency discharge port.

[0031] The clamping structure 12 is fixedly mounted on the frame, and its position corresponds to a preset station at the outlet end of the guide rail chute 13. (See also...) Figure 5The clamping structure 12 has an internal cavity containing at least one spring 21 and a pair of relatively movable clamping plates 22. The preload of the spring 21 keeps the two clamping plates 22 in a closed or slightly closed state in their natural state. When hot material falls from the aligned guide rail chute 13 and enters between the two clamping plates 22, the weight and inertia of the material will push the clamping plates 22 apart and compress the spring 21. Subsequently, under the restoring force of the spring 21, the clamping plates 22 tightly clamp the material. The inner side of the clamping plates 22 can be machined with anti-slip textures or V-shaped grooves to better adapt to materials of different shapes and increase clamping stability.

[0032] The outer shell of the clamping structure 12 is fixedly connected to a rotating wheel 10. The rotating wheel 10 is rotatably supported in a bearing seat of the frame via a rotating shaft 20. One end of the rotating shaft 20 is directly connected to the output shaft of the rotary motor 9 via a coupling or via a reducer. The rotary motor 9 is typically a servo motor or a stepper motor to precisely control the rotation angle. After the clamping structure 12 clamps the material, the rotary motor 9 starts, driving the rotating shaft 20 and the rotating wheel 10 to rotate, thereby causing the clamping structure 12 and the material it clamps to rotate together. Its rotation trajectory is designed so that after rotating horizontally at a certain angle from the initial receiving position, it moves exactly above the support platform 19.

[0033] The support platform 19 is a fixed, horizontal platform located below the rotation path of the clamping structure 12. Its surface is flat and robust, designed to receive material released from the clamping structure 12. A first push motor 11 is installed on the rear side of the support platform 19, i.e., the side facing away from the forging die 18. The output shaft of the first push motor 11 is connected to a push mechanism, which can be a separate push rod or a combination of the aforementioned first push rod 5 applied in a different position. After the material has been forged on the support platform 19, the first push motor 11 drives the push rod to push the finished material out from the front edge of the support platform 19, allowing it to fall into the finished product collection box or enter the next conveyor line.

[0034] The forging die 18 is disposed on the front side of the bearing platform 19, adjacent to its edge. The forging die 18 typically consists of an upper die and a lower die, with the lower die fixed to the front side of the bearing platform 19. The rear end of the moving die portion of the forging die 18, such as the upper die, is connected to a second push rod 8. The rear end of the second push rod 8 is connected to the power output end of the forging machine 7. The forging machine 7 is a standard forging device such as a hydraulic press or a crank press, which provides enormous forging pressure. When the material is placed in the forging station of the bearing platform 19, i.e., below the die cavity, the forging machine 7 operates, driving the moving die portion of the forging die 18 downward through the second push rod 8, forging the material on the bearing platform 19 to produce plastic deformation and obtain the desired shape.

[0035] The workflow of this invention is briefly described as follows: The operator places multiple blank materials on the placement platform 1. Under the action of gravity, the materials slide down the drop platform 2 and enter the heating platform 16, where they are heated to a red-hot state by the heating plate 3. The heated materials slide to the pushing platform 4 and are blocked and positioned by the anti-fall plate 23. The first push rod 5 is activated, pushing the materials into the slide 6. The materials slide down the slide 6 to the changing track slide 13. At this time, the second push motor 15 has adjusted the outlet of the changing track slide 13 to align with the clamping structure 12 through the second push rod 14. The materials fall into the clamping structure 12 and are automatically clamped by the spring 21 and clamping plate 22 inside. Subsequently, the rotation motor 9 is activated, driving the clamping structure 12 to rotate through the rotating wheel 10 and rotating shaft 20, transferring and releasing the materials onto the support platform 19. The forging machine 7 then drives the forging die 18 to forge the materials through the second push rod 8. After forging is completed, the first push motor 11 drives the push rod to push the finished product out of the bearing platform 19, thus completing a fully automatic forging cycle.

[0036] In summary, this invention integrates a flexibly adjustable material conveying system with a precise and coordinated clamping and transfer mechanism to construct a complete automated forging feeding solution. Specifically, the variable-track chute 13 can switch positions under the drive of the second push rod 14 and the second push motor 15, thereby changing the path of the material after it falls out of the chute 6 and giving the system the flexibility to adapt to different process layouts. The clamping structure 12 adopts an elastic design with built-in springs 21 and clamping plates 22, which can reliably grasp high-temperature materials and simplify the clamping drive mechanism, improving reliability. Through the linkage of the rotating wheel 10, rotating shaft 20 and rotating motor 9, the clamping structure 12 realizes precise rotational transfer from the receiving station to the forging station, ensuring that the material is accurately placed in the predetermined position on the support platform 19. Throughout the process, the anti-fall barrier 17 and anti-fall plate 23 effectively prevent materials from accidentally falling off. The first push rod 5 and the first push motor 11 are responsible for the linear propulsion of the materials and the ejection of the finished products. The heating plate 3, forging die 8, and forging machine 7 respectively complete the core processes of heating, forming, and forging the materials. The sequential connection and coordinated operation of each component realizes full automation from stacking, heating, transfer, forging to unloading. This not only significantly improves production efficiency and safety, but also ensures the stability of forging quality through precise alignment and reliable clamping, fundamentally overcoming the technical defects of rigid paths, inaccurate docking, and complex mechanisms in existing technologies.
