Description

Technical Field

[0001] This utility model relates to the field of medium-frequency forging furnace heating technology, and in particular to an automatic pneumatic feeding mechanism for a medium-frequency forging furnace. Background Technology

[0002] Medium-frequency forging furnaces are modern metal billet heating equipment based on the principle of electromagnetic induction heating. With their significant advantages such as high efficiency, precision, energy saving, and environmental friendliness, they have become an indispensable core heating device in the modern forging industry. This equipment is widely used in forging processes in automotive parts, construction machinery, aerospace, and military manufacturing, and is also suitable for metal hot forming and heat treatment processes. Its core technology utilizes medium-frequency alternating current (between 1-10kHz) to generate a high-intensity alternating electromagnetic field in the surrounding space when passed through an induction coil made of a specially designed copper tube. When the metal billet is placed in this alternating magnetic field, according to the law of electromagnetic induction and the skin effect, strong eddy currents are generated inside the metal. These eddy currents rapidly convert electrical energy into heat energy under the action of the metal resistance, thus uniformly heating the metal billet to the temperature range required for forging in a very short time.

[0003] However, the efficient medium-frequency heating process relies on a stable and continuous supply of billets (feeding). Currently, many forging production lines still rely on semi-automatic equipment or completely manual operation in the feeding stage. Operators need to frequently manually pick up and load materials in the high-temperature radiation area. This method has significant drawbacks: on the one hand, workers are exposed to the high temperature and high radiation near the furnace mouth for a long time, facing extremely high safety risks such as burns, thermal radiation burns, and possible mechanical pinching injuries, resulting in a harsh working environment; on the other hand, the slow pace and intermittent nature of manual operation make it difficult to match the efficient heating capacity of the medium-frequency furnace, becoming a bottleneck restricting the improvement of overall production efficiency. This inefficient and unsafe feeding method is incompatible with the trend of modern and intelligent forging production. Utility Model Content

[0004] In order to overcome the shortcomings of existing semi-automatic or manual feeding methods, which have high safety risks and low efficiency, the technical problem is to provide an automatic pneumatic feeding mechanism for medium-frequency forging furnaces.

[0005] The technical solution of this utility model is: an automatic pneumatic feeding mechanism for a medium-frequency forging furnace, including a frame, a support frame, a medium-frequency forging furnace, mounting plates, placement plates, connecting plates, limit plates, lifting plates, electric cylinders, guide rods, and springs. A support frame is fixedly connected to the middle of the top of the frame. The medium-frequency forging furnace is installed on the left side of the top of the frame. Mounting plates are symmetrically fixedly connected to the front right side of the top of the frame. A placement plate is fixedly connected between the lower front sides of the two mounting plates. A connecting plate is fixedly connected between the rear sides of the two mounting plates. The same limiting plate is fixed between them, and the limiting plate is located on the right side of the support frame. A lifting plate slides between the placement plate, the connecting plate and the limiting plate. The lifting plate is U-shaped and has a front-low and rear-high design. An electric cylinder is installed at the bottom of the frame. The extension rod of the electric cylinder is connected to the bottom of the lifting plate. Guide rods are vertically inserted on the front and rear sides of the lower part of the lifting plate, and the other ends of the two guide rods are fixed to the top of the frame. Springs are connected between the front and rear sides of the lower part of the lifting plate and the top of the frame, and the two springs are respectively sleeved on the outside of the two guide rods.

[0006] Furthermore, it also includes a guide rail, a fixed frame, a cylinder, and a push plate. The guide rail is installed on the upper rear side of the limit plate, and the fixed frame is fixedly connected to the right rear side of the top of the frame. A cylinder is installed on the top of the fixed frame, and the cylinder extension rod is connected to the push plate. The rear part of the other end of the push plate is slidably connected to the guide rail, and the front part of the other end of the guide rail is slidably in contact with the top of the limit plate.

[0007] Furthermore, it also includes a slide and a collection frame. The slide is fixed to the left side of the medium-frequency forging furnace, and the collection frame is fixed to the left side of the frame, with the slide located above the collection frame.

[0008] Furthermore, the tops of the placement plate, connecting plate, and lifting plate are all designed with an angle.

[0009] Furthermore, an arc-shaped groove is provided on the top of the lifting plate to facilitate a more stable material rolling process.

[0010] Furthermore, the support frame, mounting plate, limit plate, and slide are all made of high-temperature resistant materials.

[0011] The beneficial effects are: 1. This utility model achieves automatic lifting, conveying and feeding of materials into the furnace through the coordinated action of electric cylinder, lifting plate and push plate and other mechanisms, reducing manual intervention, increasing the feeding speed and improving efficiency by several times compared with manual operation.

[0012] 2. This utility model eliminates the need for workers to manually feed materials in high-temperature radiation areas, avoiding safety hazards such as high-temperature burns and mechanical pinching injuries, thus improving safety. Attached Figure Description

Detailed Implementation

[0019] Example: An automatic pneumatic feeding mechanism for a medium-frequency forging furnace, such as Figures 1-5 As shown, the assembly includes a frame 1, a support frame 101, a medium-frequency forging furnace 2, a mounting plate 3, a placement plate 4, a connecting plate 5, a limiting plate 6, a lifting plate 7, an electric cylinder 8, a guide rod 9, and a spring 10. The support frame 101 is fixedly connected to the middle of the top of the frame 1. The medium-frequency forging furnace 2 is installed on the left side of the top of the frame 1. Mounting plates 3 are symmetrically fixed to the front right side of the top of the frame 1. A placement plate 4 is fixedly connected between the lower front sides of the two mounting plates 3. A connecting plate 5 is fixedly connected between the rear sides of the two mounting plates 3. The same limiting plate 6 is fixedly connected between the rear sides of the two mounting plates 3, and the limiting plate 6 is located to the right of the support frame 101. A lifting plate 7 slides between the placement plate 4, the connecting plate 5, and the limiting plate 6. The lifting plate 7 is U-shaped and has a lower front and higher rear design. A guide rod 9 is fixedly installed inside the bottom of the frame 1. The electric cylinder 8 has its telescopic rod connected to the bottom of the lifting plate 7. Guide rods 9 are vertically inserted through the front and rear sides of the lower part of the lifting plate 7, and the other ends of the two guide rods 9 are fixed to the top of the inner frame 1. Springs 10 are connected between the front and rear sides of the lower part of the lifting plate 7 and the top of the inner frame 1, and the two springs 10 are respectively sleeved on the outside of the two guide rods 9. The lifting plate 7 also includes a slide 14 and a collection frame 15. The slide 14 is fixed to the left side of the medium frequency forging furnace 2, and the collection frame 15 is fixed to the left side of the frame 1. The slide 14 is located above the collection frame 15. The placement plate 4, the connecting plate 5, and the top of the lifting plate 7 are all inclined. The top of the lifting plate 7 has an arc groove to facilitate a more stable material rolling process. The support frame 101, the mounting plate 3, the limiting plate 6, and the slide 14 are all made of high temperature resistant material.

[0020] like Figure 1 , Figure 2 and Figure 5As shown, it also includes a guide rail 11, a fixed frame 13, a cylinder 131 and a push plate 12. The guide rail 11 is installed on the upper rear side of the limiting plate 6. The fixed frame 13 is fixedly connected to the right rear side of the top of the frame 1. The cylinder 131 is fixedly installed on the top of the fixed frame 13. The extension rod of the cylinder 131 is connected to the push plate 12, and the rear part of the other end of the push plate 12 is slidably connected to the guide rail 11. The front part of the other end of the guide rail 11 slides in contact with the top of the limiting plate 6.

[0021] When workers need to automatically feed and heat-treat materials (the material addressed in this technical solution is a common cylindrical metal billet), the metal billet rolls down along the placement plate 4 to the top front of the lifting plate 7 and contacts the front side of the connecting plate 5. At this time, the electric cylinder 8 is activated, the telescopic rod of the electric cylinder 8 extends and drives the lifting plate 7 to rise. At this time, all springs 10 are compressed, and the material at the top front of the lifting plate 7 also rises. When the top front of the lifting plate 7 rises to the same height as the top of the connecting plate 5, the material at the top front of the lifting plate 7 will roll down to the top of the connecting plate 5. Then, the electric cylinder 8 is activated again, the telescopic rod of the electric cylinder 8 retracts and drives the lifting plate 7 to descend. At this time, all springs 10 are stretched. When the top front of the lifting plate 7 descends back to its original position, the next material at the back of the top of the placement plate 4 will roll down to the top front of the lifting plate 7, and at this time the lifting plate... The top of the rear of the lifting plate 7 will be at the same height as the top of the connecting plate 5. Then, the material at the top of the connecting plate 5 will roll down to the top of the rear of the lifting plate 7. Then, the electric cylinder 8 will be activated. The telescopic rod of the electric cylinder 8 will extend again and drive the lifting plate 7 to rise. When the top of the rear of the lifting plate 7 is at the same height as the limiting plate 6, the material at the top of the rear of the lifting plate 7 will roll down to the top of the limiting plate 6. Then, the cylinder 131 will be activated. The telescopic rod of the cylinder 131 will extend and drive the push plate 12 to move to the left. The push plate 12 will push the material at the top of the limiting plate 6 to move to the left and enter the medium frequency forging furnace 2 through the support frame 101. After heat treatment, the material will be discharged from the left side of the medium frequency forging furnace 2 and finally fall on the top of the slide 14 and slide down the slope into the collection box 15. Then, the above operation is repeated for automatic feeding and heat treatment. At this time, the automatic feeding and heat treatment of the material is completed.
