[0003] Its core features include:

[0004] · Performance advantages: Compared with castings, forgings have denser internal structures and better mechanical properties (such as strength and toughness) due to the extrusion effect.

[0005] · Process types: mainly include hot forging (high temperature plastic forming), warm forging (medium temperature) and cold forging (room temperature), suitable for different metal materials and precision requirements.

[0006] Forging dies that facilitate discharge are designed to meet basic functions and are optimized for the discharge process. Their structural features include an optimized die cavity design, which makes it easier for forgings, especially those with complex shapes or internal cavities, to be discharged from the die cavity after forging, thus avoiding the situation where they become stuck and difficult to remove.

[0007] Currently, forging dies on the market are used to facilitate material discharge. The material is ejected from the die through an ejection structure for discharge.

[0042] The forging box 1, the dust collection box 51 and the solid-state induction heating box 61 are all electrically connected to an external power supply; the external power supply of the forging box 1 is connected to drive the upper module 2 to move vertically downward, and the upper module 2 cooperates with the lower module 4 to complete the forging of the material; the dust collection box 51 is driven to connect to the external power supply and generate negative pressure to suck the impurities remaining in the movable forming cavity box 41 into the dust collection box 51; the solid-state induction heating box 61 is driven to connect to the external power supply, and the solid-state induction heating box 61 is used to control the heating range of the induction coil 65, and transfer electrical energy to the induction coil 65 through the connecting line 62.

After the forging of the material is completed, the cylinder 45 is driven by the switch 417, and the cylinder 45 pushes the push plate 46 to move upward. The first telescopic rods 47 on both sides of the bottom of the push plate 46 extend and limit the push plate 46 to prevent the angle of the push plate 46 from shifting. After the push plate 46 moves upward, the first connecting rods 412 on both sides of the push plate 46 contact the arc groove of the limit plate 410. When the first connecting rod 412 rotates at the first limit rod 414, it drives the second connecting rod 413. The second connecting rod 413 pushes the sliding plate 416, and the sliding plate 416 moves upward The second telescopic rod 49 in the groove 48 is extended and limits the sliding plate 416 to prevent the angle of the sliding plate 416 from being offset, thereby pushing the ejector pin 415 and the electric push rod 418.

The invention is easy to operate, and to the greatest extent ensures that the workpiece is reduced in damage or distortion due to the ejection force when the workpiece is discharged, and has high reliability.

[0044] After the forged material is taken out, the dust collection box 51 is driven to connect to the external power supply and generate negative pressure, pulling the dust collection head 57 and aligning the dust collection head 57 with the movable forming cavity box 41. When the dust collection head 57 is pulled, the second spring 56 is deformed by the force, and the impurities remaining in the movable forming cavity box 41 are sucked out from the adsorption head and adsorbed from the dust collection pipe 52 into the dust collection box 51 to prevent the impurities from remaining in the movable forming cavity box 41 and affecting the forging of the next group of materials. After the impurity adsorption is completed, the adsorption head is released, and the second spring 56 pulls the adsorption head and moves the adsorption head into the holding block 55. The screen 58 provided inside the adsorption head is used to block impurities with a volume larger than the sieve hole to prevent impurities with a volume larger than the sieve hole from clogging the dust collection pipe 52. The first fixing ring 53 and the second fixing ring 54 set are used to limit the dust collection pipe 52 to prevent the dust collection pipe 52 from being squeezed and damaged by the vertically sliding fixing sleeve 21, which affects the adsorption of impurities in the movable forming cavity box 41.

[0045] In order to prevent the material after forging from adhering to the movable forming cavity box 41, when the movable forming cavity box 41 needs to be preheated, the solid-state induction heating box 61 is driven to connect to an external power supply. The solid-state induction heating box 61 is used to control the heating range of the induction coil 65, and the electric energy is transmitted to the induction coil 65 through the connecting line 62. When the movable forming cavity box 41 moves vertically back and forth in the slide groove 43, the induction coil 65 is used to preheat the movable forming cavity box 41. Electromagnetic induction heating generates eddy currents inside the mold through alternating current to achieve rapid heating. The ejector pin 415 and the electric push rod 418 of the movable forming cavity box 41 made of high carbon steel can still maintain high mechanical strength at high temperatures. The thermal insulation cotton 66 bonded to the fixed plate 42 is used to prevent heat from being transferred from the third cavity 419 to the second cavity 44.
