Embodiment 1

[0021] Such as figure 1 shown.

[0022] A method for preparing a funnel plate of a harbor bucket wheel machine, comprising the following steps:

[0023] First, the funnel plate is prepared according to the existing conventional manufacturing process, and the nano-scale mixed powder for high-temperature vacuum infiltration is prepared for use. The mixed powder is composed of carbon, boron, titanium, tungsten, chromium, vanadium, iron and trace elements , wherein the weight percentage of carbon is 0.2~0.5%, the weight percentage of boron is 1~2%, the weight percentage of titanium is 40~50%, the weight percentage of tungsten is 2~3%, the weight percentage of chromium is 2~3 %, the weight percentage of vanadium is 4~6%, the weight percentage of iron is 34~50%, and the rest are trace elements (such as lanthanum oxide, cerium oxide, etc.), and the powder is nano-scale.

[0024] Secondly, the billet is sent to the hammer forging room 1 for repeated hammering, so that the internal s...

Embodiment 2

[0028] Such as figure 1 shown.

[0029] A port bucket wheel machine funnel plate preparation device, which is mainly composed of a hammer forging room 1, a conveyor belt 2, a surface treatment room 3, a transfer table 4, a cryogenic treatment room 5, a controller 6 and a computer 7; wherein:

[0030] The hammer forging room 1 is mainly composed of a hammer head 1-1, a hammer head 1-2 and a workbench 1-3. The funnel plate blank of the port bucket wheel machine is installed on the workbench 1-3, and through the computer 7 and the controller 6. Control the hammer head 1-1 and hammer head 1-2 in the hammer forging room 1 to beat the blank. After beating, the thickness of the workpiece is required to be reduced by 0.5~1mm, and the beating part is required to be beaten evenly;

[0031] The surface treatment room 3 is mainly composed of an air extraction hole 3-1, a heating wire 3-2, a left heating furnace door 3-3, a workpiece clamping table 3-4, a right heating furnace door 3-5, a...

Abstract

The invention discloses a fabrication method and a device for a funnel board of a port bucket wheel machine. The fabrication method is characterized in that the method comprises the following steps: firstly, a blank is hammered repeatedly to allow an internal organization of the blank to become lath-shaped; secondly, the hammered blank is sent into a surface treatment stove for vacuum seepage layer treatment; and thirdly, the blank after the vacuum seepage layer treatment is subjected to air cooling to a room temperature, and then sent into subzero equipment for liquid nitrogen subzero treatment to achieve grain refining. The organization is densified, and the wear-resisting property and corrosion-resisting property of the funnel board are improved. The device mainly comprises a hammer forging chamber (1), a conveyor belt (2), a surface treatment chamber (3), a conveying table (4), a subzero treatment chamber (5), a controller (6) and a computer (7). The fabrication method and the device can obviously prolong the service life of a funnel of the bucket wheel machine, and the service life of the funnel of the bucket wheel machine manufactured with the method is about 3 times greater than that of the untreated funnel of the bucket wheel machine.

Description

technical field [0001] The present invention relates to a kind of mechanical manufacturing method, especially a kind of preparation method and device of port equipment, specifically a kind of preparation method and device of funnel plate of port bucket wheel machine Background technique [0002] At present, the bucket wheel machine is the equipment with the highest utilization rate in the port equipment, which is not only used for stacking coal in the cargo yard, but also used when picking up coal in the cargo yard. Every time the bucket turbine funnel takes coal, the coal flowing into the funnel will have a great impact on the funnel. In addition, the friction of coal on the funnel plate and the corrosion of coal make the funnel a frequently replaced part of the bucket turbine. In addition, the funnel The location is particularly complicated on the bucket wheel machine, and it is very inconvenient to replace, so it is imminent to design and manufacture a method that can...
