Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and in particular to a heating device for forging dies. Background Technology

[0002] In the forging process, forging die heating equipment is an indispensable key piece of equipment. The forging process requires heating the die to a suitable temperature, which not only reduces the deformation resistance of the metal material, making the metal easier to flow and form, but also reduces the friction between the die and the metal billet, extends the die's service life, and improves the forming quality and dimensional accuracy of the forgings.

[0003] However, existing forging die heating equipment has significant shortcomings. Most traditional equipment only has a single heating function. After forging is completed, manual removal of the die is often required using tools such as pry bars and ejector devices. This manual removal method is not only labor-intensive and time-consuming, but also poses high safety risks. Utility Model Content

[0020] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0021] To address the problems existing in the background technology, this application proposes the following technical solution: a forging die heating device, comprising a base 1, foot pads fixedly connected to the bottom of the base 1, a frame 2 fixedly connected to the base 1, a hydraulic cylinder 3 fixedly connected to the frame 2, a connecting plate 4 fixedly connected to the output end of the hydraulic cylinder 3, an upper die seat 5 fixedly connected to the connecting plate 4, a flipping plate 17 provided on the base 1, a lower die seat 6 fixedly connected to the top of the flipping plate 17, a heat insulation shell 7 covering both the upper die seat 5 and the lower die seat 6, a heat insulation cavity provided in the heat insulation shell 7, the heat insulation cavity being filled with heat insulation material, an electromagnetic induction heating coil 8 provided inside the heat insulation shell 7, and a driving assembly for driving the flipping plate 17 to flip on the base 1; in forging production, the heating temperature and stability of the die play a key role in the quality of the forgings, and the hydraulic cylinder 3 on the frame 2 provides power for the up and down movement of the upper die seat 5, enabling precise control of the forging pressure and stroke. The heat-insulating shell 7 outside the upper die holder 5 and the lower die holder 6, as well as the heat-insulating material inside the heat-insulating cavity, effectively reduce heat loss and improve energy utilization efficiency. They also prevent operators from being burned by contact with the high-temperature shell, thus enhancing equipment safety. The electromagnetic induction heating coil 8 inside the heat-insulating shell 7 heats the die using the principle of electromagnetic induction. This heating method offers rapid heating, good heating uniformity, and precise temperature control, meeting the temperature requirements of different forging processes. The drive assembly on the base 1 drives the tilting plate 17 to rotate, facilitating demolding and removal of forgings, greatly improving production efficiency. This design integrates heating, forging, and demolding functions.

[0022] In this embodiment, a mounting plate 15 is fixedly connected to the base 1, and a rotating shaft is rotatably connected to the outside of the mounting plate 15. The rotating shaft is fixedly connected to the flipping plate 17. The mounting plate 15 on the base 1 provides stable support and a rotational foundation for the rotating shaft. The rotating shaft is fixedly connected to the flipping plate 17, and when the drive assembly drives the rotating shaft to rotate, it can drive the flipping plate 17 to rotate synchronously. This structural design makes the rotation of the flipping plate 17 more stable and reliable, ensuring the stability of the lower die base 6 during the flipping process. The reasonable setting of the mounting plate 15 can also adjust the height and position of the rotating shaft, making the cooperation between the flipping plate 17 and the upper die base 5 more precise, ensuring the smooth progress of the forging process. Through this structure, the power of the drive assembly can be effectively transmitted to the flipping plate 17, realizing the flipping function of the lower die base 6, providing a strong guarantee for the rapid demolding of forgings. Moreover, this rotating connection method has a simple structure, is easy to maintain and replace parts, and reduces the maintenance cost of the equipment. During long-term use, it can maintain stable performance, reduce production interruptions caused by structural loosening or failure, and improve the reliability and service life of the equipment.

[0023] In this embodiment, a fixing frame 18 is fixedly connected to the outside of the frame 2 to support the flipping plate 17. A second motor 19 is fixedly connected to the outside of the fixing frame 18, and a support plate 20 is fixedly connected to the output end of the second motor 19. The fixing frame 18 and the second motor 19 are set up to provide reliable support for the flipping plate 17 during the forging process. During forging, the upper die 5 moves downward to apply huge pressure to the workpiece. At this time, it is necessary to ensure the stability of the lower die 6 to ensure the forging quality. The second motor 19 drives the support plate 20 to rotate. When the support plate 20 rotates to below the flipping plate 17, it can provide stable support for the flipping plate 17, withstand the pressure during the forging process, and prevent the flipping plate 17 from deforming or displacing due to uneven force. This support structure can effectively improve the service life of the mold, reduce mold wear, and reduce production costs. After forging is completed, the second motor 19 drives the support plate 20 to rotate away from below the flipping plate 17, making room for the flipping plate 17 to flip and allowing the flipping plate 17 to smoothly complete the demolding action. This adjustable support structure is flexible in design and can adjust the support state in a timely manner according to production needs. This ensures the stability of the forging process without affecting the smooth demolding operation, thus improving the adaptability and production efficiency of the equipment.

[0024] In this embodiment, the drive assembly includes a mounting bracket 9 fixedly connected to the base 1, a threaded rod 10 rotatably connected to the mounting plate 15, a nut block 11 threadedly connected to the outside of the threaded rod 10, and a rack 12 fixedly connected to the outside of the nut block 11. A gear 16 is fixedly connected to the outside of the rotating shaft. To limit and guide the nut block 11, a limiting guide rail can also be fixedly connected to the outside of the mounting bracket 9. A slider is slidably connected to the outside of the limiting guide rail, and the slider is fixedly connected to the nut block 11. A pulley is fixedly connected to the outside of the threaded rod 10, and a belt is sleeved on the outside of the pulley. A motor is fixedly connected to the outside of the mounting bracket 9, and the output end of the motor is fixedly connected to the threaded rod 10. The drive assembly is the core part for realizing the flipping of the flipping plate 17. The motor drives the threaded rod 10 to rotate through the pulley and belt. The rotation of the threaded rod 10 causes the nut block 11 threadedly connected to its outside to move linearly along the threaded rod 10. The rack 12 fixed on the nut block 11 meshes with the gear 16 outside the rotating shaft, converting the linear motion of the nut block 11 into the circular motion of the gear 16, thereby driving the rotating shaft and the flipping plate 17 to rotate. The limiting guide rail and slider outside the mounting bracket 9 play a limiting and guiding role for the nut block 11, ensuring that the nut block 11 maintains a linear motion trajectory during movement, avoiding deviation, and ensuring the accuracy and stability of the transmission. This transmission method has a compact structure and high transmission efficiency, and can precisely control the flipping angle and speed of the flipping plate 17. By adjusting the rotation direction and speed of the motor, the flipping plate 17 can be rotated in both directions and at different speeds, meeting the demolding requirements of different forging processes.

[0025] The usage method of this embodiment is as follows:

[0026] The electromagnetic heating coil is activated to synchronously heat the upper mold base 5 and the lower mold base 6. After heating to a certain temperature, the heated workpiece is placed on the lower mold base 6. The hydraulic cylinder 3 is activated to drive the upper mold base 5 to move downward. Through the extrusion of the upper mold base 5 and the lower mold base 6, the workpiece can be forged into the shape inside the mold.

[0027] After completion, start the first motor 14 and the second motor 19. The second motor 19 drives the support plate 20 to rotate, so that the support plate 20 no longer supports the flip plate 17.

[0028] The first motor 14 drives the threaded rod 10 to rotate, the threaded rod 10 drives the nut block 11 to move, the nut block 11 drives the rack 12 to move, the rack 12 meshes with the gear 16, thereby driving the flipping plate 17 to rotate 180 degrees, so that the lower die base 6 can face downwards, allowing the forged workpiece to fall off automatically.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
