Description

Technical Field

[0001] The utility model relates to the technical field of die steel, and more specifically, to a toughened high-chromium hot working die steel. Background Art

[0002] Hot work die steel refers to alloy tool steel suitable for making dies for hot deformation processing of metals, such as hot forging dies, hot extrusion dies, die-casting dies, hot upsetting dies, etc. Since hot work dies work under high temperature and high pressure conditions for a long time, the mold material is required to have high strength, hardness and thermal stability, especially high thermal strength, thermal fatigue resistance, toughness and wear resistance.

[0003] At present, when these mold steel materials are used to manufacture hot forging molds, die-casting molds and hot extrusion molds, due to their low high-temperature strength, poor oxidation resistance and thermal fatigue resistance, and the mold steel used to manufacture large molds is very inconvenient to carry due to its heavy weight. Usually, lifting parts such as lifting ropes are used to lift the mold steel. However, if the lifting ropes are tied unstable, it is very easy to cause safety hazards, and it is difficult to clamp during processing, which will affect the processing accuracy. The processing accuracy will affect the quality and service life of the mold. At the same time, unreasonable structural design will also affect the service life.

[0004] After searching, the Chinese patent with publication number CN217055834U discloses a high-toughness hot-working die steel, which is provided with grooves on the side and bottom surfaces of the die steel components and at positions that do not affect its operation. The fixing parts are then connected to the plug rods, and the plug rods are then installed in the grooves. Because the fixing parts use suction cups, when two adjacent die steel components are placed close together, the suction cups are adsorbed on the adjacent die steel components. It has never been avoided that during transportation, if a die steel component set at one place accidentally falls off, it will cause the die steels set at other locations to fall off.

[0005] When the above-mentioned high-toughness hot work die steel is used in practice, the thermal fatigue resistance of the high chromium hot work die steel may be affected to a certain extent under the action of high temperature and cyclic thermal stress, which may cause cracks or peeling on the mold surface. At the same time, excessively high temperature may cause the performance of the hot work die steel to deteriorate, thereby affecting the service life of the mold and the processing quality of the product.

The water is extracted and transported to the inside of the water storage tank 5 through the delivery pipe 4. Then the water storage tank 5 transports the water to the inside of the water outlet pipe 7 through the connecting pipe 6, so that multiple atomizing nozzles 8 can convert the water into water mist and evenly spray it onto the surface of the mold steel body 22, effectively reducing the temperature of the mold steel body 22 and reducing the thermal stress concentration and deformation problems caused by temperature differences. The activated carbon filter plate 11 is then used to filter the impurities in the water droplets after the cooling is completed.

A belt 15 is installed on the outside of the driving wheel 14, and a plurality of anti-slip strips 16 are fixedly connected to the outside of the belt 15. A plurality of water leakage holes 17 are provided on the surface of the belt 15. The driving wheel 14 rotates the driven wheel 18 through the belt 15, so as to support the belt 15 to drive the conveyor plate 21 to move. The plurality of anti-slip strips 16 can effectively prevent the conveyor plate 21 from shaking during movement, which is conducive to maintaining the stability of the movement of the conveyor plate 21.

[0037] Reference Figure 4 As shown, a driven pulley 18 is installed at the right end of the inner side of the belt 15, and two driving wheels 19 are installed on the inner side of the belt 15.

The two slopes inside the conveying plate 21 can be used to concentrate the water droplets and convey them to the leakage net 24, and then the water can be discharged to the inside of the conveying plate 21 through the leakage net 24, which is convenient for collecting and centralizing the moisture.

[0039] Working principle of the utility model: This utility model designs a toughened high chromium hot working die steel, the specific structure is as shown in the attached manual Figure 1-6As shown, in the present technical solution, through the mutual cooperation between various structures, the mold steel body 22 is first placed on the support frame 23, and then the bottom ends of both sides of the conveying plate 21 are inserted into the chute 20, and then the motor 13 is started, and the motor 13 is used to drive the driving wheel 14 to rotate, and the driving wheel 14 can be rotated to connect the driven wheel 18 to rotate, and then the two driving wheels 19 are used to support the top of the belt 15 to drive the conveying plate 21 to move, and the two chutes 20 can provide a guiding effect for the movement of the filter screen 12, and then the water pump 3 is started again, and the water pump 3 uses the water pumping pipe 9 to extract the water inside the water collecting tank 10, and then the water is transported to the inside of the water storage tank 5 through the delivery pipe 4, and the water storage tank 5 transports the water to the inside of the water outlet pipe 7 through three connecting pipes 6, so that multiple atomizing nozzles 8 can be sprayed on the surface of the mold steel body 22 through atomization, which is convenient for cooling and dissipating the surface of the mold steel body 22 The multiple anti-slip strips 16 on the surface of the belt 15 can effectively prevent the conveying plate 21 from shaking. At the same time, the belt 15 is used to drive the conveying plate 21 to move at a constant speed, so that the water mist can be evenly sprayed onto the surface of the mold steel body 22. When the water mist contacts the surface of the mold steel body 22 and is converted into water droplets due to the high temperature, the water droplets will pass through the support frame 23 and flow to the inner bottom end of the conveying plate 21, and then drip onto the belt 15 through the filter 24. The multiple anti-slip strips 16 on the surface of the belt 15 are used to facilitate the water droplets to flow to the inner bottom end of the workbench 1, and after being filtered by the filter 12, they drip into the water collecting tank 10, and then the impurities in the water are filtered again by the activated carbon filter plate 11. The filtered water will stay at the bottom end of the water collecting tank 10. Finally, the water pump 3 can use the water pipe 9 to transport the water in the water collecting tank 10 back to the water storage tank 5, thereby realizing the recycling of cooling water.
