Description

Technical Field

[0001] This utility model relates to the field of hot work die steel technology, specifically to a rapid mist cooling device for hot work die steel. Background Technology

[0002] Hot work die steel refers to a general term for die materials that can withstand impact loads, thermal fatigue, and wear during the manufacturing process. Hot work die steels such as H13 and 3Cr2W8V require rapid cooling at high temperatures of 600°-700°C.

[0003] According to the Chinese patent publication CN222125534U, "A Quick-Cooling Device for Hot Work Die Steel," the device mainly utilizes the interaction of a motor, half gear, rotating rod, full gear, spring, rotating shaft, and fixed rod to rotate the atomizing nozzle back and forth to spray water, maximizing the cooling efficiency of the hot work die steel. Simultaneously, the water intake pipe, outlet pipe, and pump can recycle used wastewater, saving water resources. Furthermore, the filter plate can clean the used wastewater before reuse, preventing debris from clogging the nozzle and extending the device's lifespan.

[0004] Common hot work die steels are cooled by atomization using a water tank and atomizing nozzles. The steel is then moved by a conveyor belt to achieve rapid cooling. Furthermore, filtering the wastewater prevents debris from clogging the nozzles after recycling, thus extending the service life of the equipment.

[0005] However, the atomizing nozzles used for hot work die steel are often located on the upper side of the die steel. During the cooling process, the cooling rate of the upper part of the die steel is greater than that of the bottom side. The thermal stress exceeds the yield strength of the hot work die steel, resulting in non-uniform cooling stress inside the die steel and the formation of thermal fatigue cracks. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a rapid mist cooling device for hot work die steel, which improves the consistency of cooling rates between the upper and lower sides of the die steel and reduces thermal fatigue cracks.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a rapid mist cooling device for hot work die steel, including a water-holding frame and a processing frame. The processing frame is located on the upper side of the water-holding frame. A support rod is inserted into the bottom side of the processing frame. Two limiting rings are threaded onto the support rod. A support plate is fixedly connected to the upper end of the support rod. A sprocket is evenly rotatably connected to one side of the two support plates. A drive motor is fixedly connected to one side of the support plate, and the output end of the drive motor is fixedly connected to one of the sprockets. A transmission chain is sleeved on the sprocket. The two opposing sprockets are fixedly connected. The device includes guide rollers, and an adjusting sleeve is rotatably connected to the center of the two support plates at their opposite ends. A limit rod is threaded into the adjusting sleeve, and a water distribution pipe is fixedly connected to the end of the limit rod away from the support plate. A top water guide pipe is evenly fixedly connected to the side of the water distribution pipe away from the water-holding frame, and a bottom water guide pipe is evenly fixedly connected to the side of the water distribution pipe near the water-holding frame. An atomizing nozzle is fixedly connected to one end of both the top and bottom water guide pipes. A water pump is fixedly connected to both sides of the treatment frame, and a metal hose is fixedly connected to the output end of the water pump. One end of the metal hose is fixedly connected to the water distribution pipe and is internally connected to it.

[0008] As a preferred technical solution of this utility model, the upper sides of the support plate are fixedly connected with clamping rods, and L-shaped plates are sleeved on the clamping rods. An auxiliary wheel is rotatably connected to the side of the L-shaped plate away from the sprocket. By setting the clamping rods, L-shaped plates and auxiliary wheels, the stability of the movement of hot work die steel can be improved, and sufficient gap between two adjacent guide rollers can be ensured.

[0009] As a preferred technical solution of this utility model, the upper side of the clamping rod is threaded with an extrusion disc, and the bottom end of the extrusion disc contacts the upper end of the L-shaped plate. By setting the extrusion disc, the stability of the L-shaped plate can be further increased.

[0010] As a preferred technical solution of this utility model, each of the two support plates has a through hole on its opposite side and an auxiliary rod is inserted into the through hole. The auxiliary rod is located between the two water distribution pipes. By setting the auxiliary rod, the water distribution pipe can be limited, which facilitates the provision of support on both sides of the water distribution pipe.

[0011] As a preferred technical solution of this utility model, the auxiliary rod is threadedly connected to a connecting ring at the end away from the support plate. The connecting ring is fixedly connected to one side of the water distribution pipe. By setting the connecting ring, the water distribution pipe can be replaced, thereby adaptably replacing the auxiliary rod according to the distance between the adjusting sleeve and the limiting rod, and providing a limiting position.

[0012] This utility model has the following advantages:

[0013] (1) By setting multiple and evenly distributed top water pipes and bottom water pipes between rotating guide rollers, the contact surface between atomized water and hot work die steel can be increased, the heat dissipation uniformity of hot work die steel can be improved, the uniform cooling of die steel can be improved, and thermal fatigue damage can be reduced.

[0014] (2) By adjusting the sleeve and the limiting rod, and with the auxiliary rod that can be disassembled and replaced with a suitable length, it can provide a connection between the water distribution pipe, the top water guide pipe and the bottom water guide pipe, and facilitate the adjustment of the position of the atomizing nozzle, so as to adapt to different sizes of mold steel.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] Please refer to the following: Figure 1-4The device shown is a rapid mist cooling device for hot work die steel, comprising a water-holding frame 1 and a processing frame 2. The processing frame 2 has evenly spaced through holes on its bottom side for collecting the atomized water after it falls. The processing frame 2 is located above the water-holding frame 1. A support plate is installed inside the water-holding frame 1 to support the processing frame 2, and a filter screen is installed inside the water-holding frame 1 to filter the falling water. A support rod 3 is inserted into the bottom side of the processing frame 2. By setting the support rod 3 and limiting rings 4, the support plate 5 and guide roller 7 can be disengaged from the processing frame 2. Two limiting rings 4 are threaded onto the support rod 3. A support plate 5 is fixedly connected to the upper end of the support rod 3. A sprocket 6 is rotatably connected to one side of each of the two support plates 5. A drive motor drives the sprocket 6 to rotate, enabling multiple guide rollers 7 to rotate synchronously under the action of multiple conveyor chains, thus moving the mold steel. A drive motor is fixedly connected to one side of the support plate 5, and one of the sprockets 6 is fixedly connected to the output end of the drive motor. A conveyor chain is sleeved on the sprocket 6. Guide rollers 7 are fixedly connected between two opposing sprockets 6. An adjusting sleeve 8 is rotatably connected to the center of the two support plates 5 at their furthest ends. The adjusting sleeve 8, in conjunction with the limiting rod 9, enables the movement of the atomizing nozzle 13, improving the adaptability of spraying and cooling for mold steels of different sizes. The adjusting sleeve 8 is internally threaded with the limiting rod 9. A water distribution pipe 10 is fixedly connected to the end of the limiting rod 9 furthest from the support plate 5. Top water guide pipes 11 are evenly fixedly connected to the side of the water distribution pipe 10 furthest from the water-holding frame 1, and bottom water guide pipes 12 are evenly fixedly connected to the side of the water distribution pipe 10 closest to the water-holding frame 1. Atomizing nozzles 13 are fixedly connected to one end of both the top and bottom water guide pipes 11 and 12. Water pumps 14 are fixedly connected to both sides of the processing frame 2. The inlet end of the water pump 14 is connected to the bottom side of the water holding frame 1 through a pipe (not shown in the figure) and a flange (not shown in the figure). The water pump 14 draws water from the bottom side of the filter screen of the water holding frame 1, passes through the metal hose 15, the water distribution pipe 10, the top water guide pipe 11 and the bottom water guide pipe 12, and finally sprays it out through the atomizing nozzle 13 and contacts the upper and lower sides of the mold steel respectively. The output end of the water pump 14 is fixedly connected to the metal hose 15, and one end of the metal hose 15 is fixedly connected to the water distribution pipe 10 and the inside is connected.

[0022] Among them, the upper end of the support plate 5 is fixedly connected to both sides of the clamping rod 16, and the clamping rod 16 is fitted with an L-shaped plate 17. The side of the L-shaped plate 17 away from the sprocket 6 is rotatably connected to the auxiliary wheel 18. By setting the clamping rod 16, the L-shaped plate 17 and the auxiliary wheel 18, the support for the mold steel can be provided between the gaps of the two relative guide rollers 7, and the gap between the two adjacent guide rollers 7 can be sufficient to achieve the effect of easy spraying of the bottom water pipe 12 and the atomizing nozzle 13.

[0023] The upper side of the clamping rod 16 is threaded with a pressing plate 19. The bottom end of the pressing plate 19 contacts the upper end of the L-shaped plate 17. By setting the pressing plate 19, the clamping rod 16 can further stabilize the L-shaped plate 17 and the auxiliary wheel 18.

[0024] Among them, the two support plates 5 are provided with through holes on the opposite sides, and auxiliary rods 20 are inserted into the through holes. The auxiliary rods 20 are located between the two water distribution pipes 10. By setting the auxiliary rods 20, when the position is adjusted between the adjusting sleeve 8 and the limiting rod 9, the auxiliary rods 20 can provide auxiliary limiting for the water distribution pipes 10, thereby improving the stability of the water distribution pipes 10, the top water guide pipe 11 and the bottom water guide pipe 12.

[0025] The auxiliary rod 20 is threaded to a connecting ring 21 at the end away from the support plate 5. The connecting ring 21 is fixedly connected to one side of the water distribution pipe 10. By setting the connecting ring 21, the length of the auxiliary rod 20 can be further changed when the position is adjusted between the adjusting sleeve 8 and the limiting rod 9. An auxiliary rod 20 of appropriate length can be selected.

[0026] Working principle: Based on the height of the mold steel, the downward movement depth of the support rod 3 is adjusted, and then the limiting ring 4 is used for limiting. The mold steel to be cooled is then placed on the guide roller 7. The drive motor is then started, causing the sprocket 6 and the transmission chain to rotate. At this time, multiple guide rollers 7 rotate and drive the mold steel to move. Then, the water pump 14 draws water from the water frame 1 and sprays it evenly onto the top, sides and bottom of the mold steel through the metal hose 15, water distribution pipe 10, top water guide pipe 11, bottom water guide pipe 12 and atomizing nozzle 13. This reduces the probability of non-uniform cooling stress generated inside the mold steel, improves the cooling effect and reduces thermal fatigue cracks.

[0027] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0028] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
