[0002] A roll forging machine is a mechanical device used for metal processing, also known as a roll forging press. It achieves the process of forging, pressing and forming by placing the metal material between two or more rolls and applying pressure. The working principle of a roll forging machine is to pass the metal material through the pressure between the rolls to cause it to undergo plastic deformation, thereby changing its shape and size. After a long period of use, the temperature of the roll forging die will rise sharply, causing the heated bar to flow faster during the roll forging process, which in turn affects the forging efficiency of the roll forging machine. Therefore, it is necessary to cool the roll forging die in time.

[0003] The roller forging die cooling device of the prior art usually uses spraying coolant for cooling. However, spraying the coolant directly on the roller forging die is prone to splashing of the coolant, and the spraying device is usually fixed, resulting in uneven spraying, which greatly affects the cooling efficiency.

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figures 1 to 4 As shown, a roll forging die cooling device for a roll forging machine comprises a roll forging machine platform 1, wherein the upper end of the roll forging machine platform 1 is fixedly connected to a frame 2, a forging roller 3 is rotatably connected to the inner side of the frame 2, a slide groove 20 is provided at the upper end of the frame 2, sliders 4 arranged correspondingly on both sides are slidably connected in the slide groove 20, limiting slide bars 19 cooperating with the sliders 4 are provided in the slide grooves 20, the lower ends of the sliders 4 on both sides are hinged with connecting blocks 6, and the lower end surface of the slider 4 is fixedly connected to a magnetic plate, The connecting block 6 is a metal block that cooperates with the magnetic plate. The lower ends of the connecting blocks 6 on both sides are fixedly connected with an arc-shaped cover tube 5. The outer wall of the arc-shaped cover tube 5 is hinged with a hanging plate 22, and the hanging plate 22 is provided with a fixing hole 23. The frame 2 is fixedly connected with a fixing column 24 that cooperates with the fixing hole 23. The lower end of the arc-shaped cover tube 5 is provided with a drainage box 12. The outer wall of the arc-shaped cover tube 5 is provided with a drainage hole 11 connected to the drainage box 12, and a drainage pump 13 is provided on one side of the drainage box 12.

[0019] The arc-shaped cover tube 5 is fixedly connected with connecting plates 8 arranged correspondingly on both sides, and a water spray pipe 9 is rotatably connected between the connecting plates 8 on both sides. The water spray pipe 9 is fixedly connected with a nozzle 10 arranged along the length direction, and a connecting pipe 21 is fixedly connected to one side of the water spray pipe 9, and the other end of the connecting pipe 21 is fixedly connected to a water suction hose extending to the outside of the arc-shaped cover tube 5. The arc-shaped cover tube 5 is provided with a through hole that also cooperates with the water suction hose. The upper end of the connecting pipe 21 is hinged with an adjusting rod 15, and the outer wall of the arc-shaped cover tube 5 is fixedly connected to a control box 14. The arc-shaped cover tube 5 is provided with a sliding hole connected to the control box 14 and matched with the adjusting rod 15. The control box 14 is provided with a reciprocating mechanism for driving the adjusting rod 15 to slide. The reciprocating mechanism includes a rack 7 fixedly connected to the upper end of the adjusting rod 15, and a return spring 17 is fixedly connected between the rack 7 and the upper end of the control box 14. An incomplete gear 16 meshing with the rack 7 is rotatably connected in the control box 14, and a motor 18 for driving the incomplete gear 16 to rotate is fixedly connected to one side of the control box 14.

[0020] In specific use, the hanging plate 22 is flipped upward to make the fixing columns 24 on both sides extend out from the fixing holes 23, and the arc-shaped cover tubes 5 on both sides are flipped downward to make the upper end of the connecting block 6 and the lower end of the slider 4 connected and fitted through the magnetic plate, and the arc-shaped cover tubes 5 on both sides are pushed. The arc-shaped cover tubes 5 drive the slider 4 to slide along the slide rod through the connecting block 6, so that the arc-shaped cover tubes 5 on both sides are connected to each other to form a sealed space. The water suction hose passes the coolant into the connecting pipes 21 on both sides, and then sprays it on the roller forging die through the water spray pipe and the nozzle, and prevents the spray liquid from flying through the arc-shaped cover tubes 5 on both sides. The excess coolant splashes, and flows into the drain box 12 through the drain hole 11 at the lower end, and is discharged through the drain pump 13. The motor 18 is started to drive the incomplete gear 16 to rotate. When the incomplete gear 16 contacts the rack 7, the driving rack 7 pulls the adjusting rod 15 to slide upward, and the reset spring 17 is compressed and deformed. At this time, the adjusting rod 15 pulls the water spray pipe 9 to swing downward. When the incomplete gear 16 is separated from the rack 7, the restoring elastic force of the reset spring 17 pushes the adjusting rod 15, so that the water spray pipe 9 swings upward, which greatly increases the spraying area and makes the cooling more efficient.
