DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The technical solution of the present invention will be further described below with reference to the embodiments:

[0027] Example 1

[0028] In conjunction with the instructions Figure 1 This embodiment provides a production device for wear-resistant millimeter-sized particle 2-metal composite material:

[0029] The production device includes an XY tooling platform 11, a rod feeding device 1, a substrate local preheating device 7, a substrate local melting device 5, a gas protection device 4, a rod melting device 8 and a leveling device 6.

[0030] A leveling device 6 is installed on one side of the bar feeding device 1, and a localized substrate melting device 5 is installed on the other side. A localized substrate preheating device 7 is installed on the side of the localized substrate melting device 5 away from the bar melting device 8. The bar feeding device 1 is located above the gas shielding device 4, which is in turn located above the bar melting device 8. An XY tooling platform 11 is located below the bar feeding device 1, the localized substrate preheating device 7, the localized substrate melting device 5, the gas shielding device 4, the bar melting device 8, and the leveling device 6. A small hole is provided below the bar melting device 8 to allow the molten metal (along with the metal particles therein) to drip onto the XY tooling platform 11.

[0031] Furthermore, a rotating device 9 is provided above the rod feeding device 1. The rod feeding device 1, the substrate local preheating device 7, the substrate local melting device 5, the gas protection device 4, the rod melting device 8, the leveling device 6 and the rotating device 9 are an integrated structure. The rotating device 9 can rotate 360° and is used to cooperate with the plate on the XY tooling platform 11 and the metal tube melt with millimeter-level particles 2 in the rod feeding device 1 to be compounded.

[0032] A plate made of a first metal material is placed on an XY tooling platform 11, and a metal tube 3 of the first metal material containing millimeter-sized particles 2 of the second material is placed into a rod feeding device 1. The bottom of the metal tube 3 is a sealing structure to prevent the millimeter-sized particles 2 from falling onto the plate when the metal tube 3 is not melted. Open the rod feeding device 1, control the moving speed of the metal tube 3, and at the same time, open the local preheating device 7 of the substrate to preheat the plate area to be composited, and then use the mobility of the XY tooling platform 11 to move the plate area to be composited to the local melting device 5 of the substrate for melting. Since the plate is preheated before melting, the melting speed of the plate is very fast. When the plate area to be composited is moved to the bottom of the rod feeding device 1, open the gas protection device 4 and the rod melting device 8, and melt the metal tube 3 containing millimeter-level particles 2. Since the melting point of the millimeter-level particles 2 is much higher than that of the metal tube 3, the rod melting device 8 cannot melt the millimeter-level particles 2, and the molten liquid will wrap the millimeter-level particles 2. Use the small hole opened under the rod melting device 8 to drip the molten liquid onto the plate area to be composited, and then move the plate area to be composited to the leveling device 6, and hammer the area to complete the composite of the plate and the millimeter-level particles 2. The rotating device 9 can be moved 360 degrees, and the XY tooling platform 11 can be used to move the plate horizontally in the XY direction, so that the entire plate is compounded with the millimeter-sized particles 2.

[0033] In this embodiment, the localized substrate preheating device 7 and the rod melting device 8 are induction coils; the localized substrate melting device 5 is an argon arc welding torch; and the leveling device 6 can be powered by pneumatic, electric, or hydraulic means. The gas shielding device 4 is filled with a shielding gas selected from one or more of argon, nitrogen, or helium. The rod feeding device 1 can be a hydraulic or electric push rod, as long as it can feed the metal tube 3 to the rod melting device 8.

[0034] Example 2

[0035] As another embodiment of the present invention, Figure 2 , the embodiment provides a production device for wear-resistant millimeter-scale particle 2-metal composite material:

[0036] The production device includes an XY tooling platform 11, a rod feeding device 1, a substrate local preheating device 7, a substrate local melting device 5, a gas protection device 4, a rod melting device 8, a particle feeding device 10 and a leveling device 6.

[0037] A particle feeding device 10 is provided on one side of the rod feeding device 1, and a localized substrate melting device 5 is provided on the other side. A localized substrate preheating device 7 is provided on the side of the localized substrate melting device 5 away from the rod melting device 8. A leveling device 6 is provided on the side of the particle feeding device 10 away from the rod melting device 8. The rod feeding device 1 is located above the gas shielding device 4, which is in turn located above the rod melting device 8. An XY tooling platform 11 is located below the rod feeding device 1, the localized substrate preheating device 7, the localized substrate melting device 5, the gas shielding device 4, the rod melting device 8, the particle feeding device 10, and the leveling device 6. A small hole is provided below the rod melting device 8 to allow the molten metal (along with the metal particles therein) to drip onto the XY tooling platform 11.

[0038] Furthermore, a rotating device 9 is provided above the rod feeding device 1. The rod feeding device 1, the substrate local preheating device 7, the substrate local melting device 5, the gas protection device 4, the rod melting device 8, the particle feeding device 10, the leveling device 6 and the rotating device 9 are an integrated structure. The rotating device 9 can rotate 360° and is used to cooperate with the plate on the XY tooling platform 11 and the metal tube melt with millimeter-level particles 2 in the rod feeding device 1 to be compounded.

[0039] Place the plate made of the first metal material on the XY tooling platform 11, put the millimeter-sized particles 2 of the second material into the particle feeding device 10, and put the metal tube 3 made of the first metal material into the rod feeding device 1. Turn on the rod feeding device 1, control the moving speed of the metal tube 3, and at the same time, turn on the substrate local preheating device 7 to preheat the plate area to be composited. Then, using the mobility of the XY tooling platform 11, move the plate area to be composited to the substrate local melting device 5 for melting. Since the plate is preheated before melting, the melting speed of the plate is fast. The speed is very fast. When the plate area to be composited is moved to the bottom of the rod feeding device 1, the gas protection device 4 and the rod melting device 8 are opened to melt the metal tube 3. The molten melt is dripped onto the plate area to be composited using the small hole opened below the rod melting device 8. The plate area to be composited is then moved to the bottom of the particle feeding device 10. The particle feeding device 10 is opened to allow the millimeter-sized particles 2 to drip onto the plate area to be composited. The plate area to be composited is then moved to the bottom of the leveling device 6 and the area is hammered to complete the composite of the plate and the millimeter-sized particles 2. The rotating device 9 can be moved 360° and the XY tooling platform 11 can be used to move the plate horizontally in the XY direction so that the entire plate is composited with the millimeter-sized particles 2.

[0040] In this embodiment, the localized substrate preheating device 7 and the rod melting device 8 are induction coils; the localized substrate melting device 5 is an argon arc welding torch; and the leveling device 6 can be powered by pneumatic, electric, or hydraulic means. The gas shielding device 4 is filled with a shielding gas selected from one or more of argon, nitrogen, or helium. The rod feeding device 1 can be a hydraulic or electric push rod, as long as it can deliver the metal tube 3 to the rod melting device 8.

The details in the embodiments do not constitute a limitation on the scope of the present invention.
