Background technology
Fig. 1 is the copper sheathing structural representation of prior art, as it can be seen, in amorphous produces the production process of equipment, existing copper sheathing is made up of the copper alloy of hollow entity, and opens several grooves in the entity part of copper sheathing.The Main Function of copper sheathing is the contact area increasing water with copper sheathing, thus increases cooling capacity and rate of cooling.But, in process of production, the use of copper sheathing gradually uses up, and the thickness that uses of copper sheathing determines life-span and the cost of copper sheathing.If having opened groove on the thickness of copper sheathing, this segment thickness of fluting cannot be continuing with;Furthermore, slot on copper sheathing, need and following water route one_to_one corresponding, owing to slotted section spacing is less, installation difficulty is very big, and the most wrongly installed, copper sheathing will be scrapped.
Summary of the invention
It is an object of the invention to provide a kind of copper sheathing manufacture method, the problem in service life and installation difficulty to solve copper sheathing.
For achieving the above object, the invention provides a kind of copper sheathing manufacture method, the method comprises the following steps: processing and fabricating external connection portion and fluting portion, and the material of described external connection portion is copper alloy, and the material in described fluting portion is fine copper;First contact surface of described external connection portion and second contact surface in fluting portion are polished so that the roughness of described first contact surface and the second contact surface is less than 0.01;First contact surface of described external connection portion and second contact surface in fluting portion smear conduction oil;After described external connection portion being heated, interference is set in outside described fluting portion, thus forms copper sheathing, is filled with described conduction oil in the contact gap between the first contact surface and the second contact surface.
Further, the first contact surface of described external connection portion and second contact surface in fluting portion carry out polishing specifically, utilize the first contact surface of external connection portion described in nanometer grinding machine reconditioning and second contact surface in fluting portion.
Invention increases the utilization rate of copper sheathing, reduce cost of manufacture, also reduce its installation difficulty, it is adaptable to extensive amorphous produces.

Detailed description of the invention
Below by drawings and Examples, technical scheme is described in further detail.
Fig. 2 is the copper sheathing manufacture method schematic flow sheet of the embodiment of the present invention, as in figure 2 it is shown, the method comprises the steps:
Step 101, processing and fabricating external connection portion and fluting portion;
Seeing the external connection portion and the schematic diagram in fluting portion used shown in the manufacture method of the copper sheathing of the present invention shown in Fig. 3 A and Fig. 3 B, the material of external connection portion 1 is copper alloy, and the material in fluting portion 2 is fine copper, and has cell body 20 in the portion 2 that slots.
Step 102, polishes the first contact surface of external connection portion and second contact surface in fluting portion;
For another example shown in Fig. 3 A and Fig. 3 B, the first contact surface 11 of external connection portion 1 is inner surface, and second contact surface 21 in fluting portion 2 is outer surface.
Concrete, it is possible to use the first contact surface 11 of external connection portion described in nanometer grinding machine reconditioning and second contact surface 21 in fluting portion so that the roughness of described first contact surface and the second contact surface is less than 0.01.
Step 103, smears conduction oil on described first contact surface and the second contact surface;Smearing described conduction oil and can fill described first contact surface and the contact gap of the second contact surface, meanwhile, described conduction oil can also make described external connection portion reach the effect of cooling.
Step 104, after described external connection portion being heated, interference is set in outside described fluting portion, thus form copper sheathing, and the schematic diagram of the copper sheathing manufacture method copper sheathing of the embodiment of the present invention shown in Figure 4, it is filled with described conduction oil in the contact gap between described first contact surface and the second contact surface.
External connection portion is because of the restriction of material, therefore maximum temperature can not be more than, deformation or bad then may be caused if greater than maximum temperature, so the interference fit between external connection portion and fluting portion is limited by external connection portion material, the computational methods of the concrete magnitude of interference are: swell increment produced by the maximum temperature of external connection portion is exactly the maximum interference amount of external connection portion, therefore, in actual manufacture, it is slightly less than maximum interference amount the most permissible.
In use, copper sheathing can produce abrasion, after reaching the limit of wear, it is possible to use said method changes an external connection portion, thus reuses fluting portion, decreases the abrasion of external connection portion.
Above-described detailed description of the invention; the purpose of the present invention, technical scheme and beneficial effect are further described; it is it should be understood that; the foregoing is only the detailed description of the invention of the present invention; the protection domain being not intended to limit the present invention; all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. done, should be included within the scope of the present invention.
