Embodiment 1

[0019] The online plasma cleaning and surface modification method of the first aluminum finned tube forming tool comprises the following steps in turn:

[0020] 1) The forming tool on the finned tube forming production line is installed on the fuselage with an insulating tool holder, so that the tool holder and the fuselage are insulated; the fuselage and the ground are also isolated with insulating materials; the insulating tool holder is used The purpose is that when the pulse voltage is applied, it is not necessary to energize through fragile parts such as bearings, so as to avoid local high temperature ablation.

[0021] 2) Slidingly connect the anode of the power supply to the tool holder, and use the carbon brush to elastically contact the tool holder, so that when the tool holder rotates, the carbon brush sticks to the tool holder to maintain electrical connection; the carbon brush can be made of graphite material, Can also be made of copper.

[0022] 3) Connect the ca...

Abstract

The invention relates to an online plasma cleaning and surface modifying method of an aluminum finned tube forming cutter in the technical field of cutter repair. The lower side of an edge of the aluminum finned tube forming cutter is dipped in plasma cleaning liquid; the forming cutter is used as an anode; a polar plate in the plasma cleaning liquid is used as a cathode; and pulse voltage is loaded to cool, clean and reinforce the cutter. The method is mainly applied to online repair of the aluminum finned tube forming cutter, and can largely prolong the service life of the forming cutter.

Description

technical field [0001] The invention relates to a method for cooling, cleaning and repairing a tool, in particular to a method for cooling, cleaning and repairing a finned tube forming tool. Background technique [0002] In the prior art, most cutting tools are made of cemented carbide or high-speed steel, which require high hardness, wear resistance, and extrusion resistance. The base material is squeezed by the high-speed rotation of the tool. During the processing, the side of the tool is always in a state of friction, and the tip of the blade is always squeezing the base material. The processing environment is very harsh. This also results in limited tool life, increasing usage and maintenance costs. Usually, when the tool is being formed, it is necessary to use coolant to cool the tool. This cooling method is often used to cool the tool by spraying. The coolant takes away the heat and makes the tool hard. However, this cooling method cannot It has the function of repa...
