As described above, the rotating workpiece 2 is used to drive the tubular workpiece 3 to rotate along the line, and the forging material 4 is poured into the workpiece 3 in the filling step 14: the shaft in the coating step 15 causes the plating material 4 to follow the workpiece The rotation of 3 is applied to the entire inner surface of the workpiece 3 to obtain a uniform predetermined film thickness. Thus, the outer peripheral surface of the workpiece 3 can be completely prevented from being plated, and the cost of the P material can be greatly increased. 11 201000654 Read more in Figure 1 and in conjunction with Figure 8, the second age society of the tubular worker I of the present invention - the inner surface coating method of the s-shaped workpiece of the hairy month - the preferred poor example, also includes: preparation step 12, ex ante Persimmon η Π homesickness, women's step processing step 13, filling step 14, coating the bovine step 16. I repeat step 15, and the hard difference is that the preparation step η further means that the device 2 and the tube worker have covered the rotation, "the large workpiece 3 insulation device 7. The insulation cover 70, and is far from the兮#屯戒置7 has a lie, and on the heat shield body 70, and relative to the 仵, 罝 罝 body 70 in order who 耔鲂 „ from Dusi ^ ... multi-protective coffee cover insulation device 7 :: door panel 71 and second door panel 72. When the tubular worker can cover the rotating device 2 and the main body of the money film to perform the money film operation, the time of the (4) 4 counts in the workpiece 3 can be maintained - the preset β series is 4 long to make the workpiece U To ensure the stability of the mineral film operation, and thus the component 3 has a better quality. As shown in Figures 8 and 9, when the heat insulating device 7 is in use, the first door panel 71 is first opened, and the first door is opened upwards, and the first and the first plates are opened. After 71 and 72 are successively opened, they can be used for filming operations, operations, inspections, or handling. : 】: The opening and closing action ‘ can also push the first air brothers m and 72 to open and close by a hydraulic cylinder or a pneumatic cylinder to make the invention overall save time and effort. The F system is further described as follows: The inner surface mineral film method of the tubular workpiece of the present invention utilizes the rotary device 2 of the step: in the mounting step U, the workpiece 3 is placed in the positioning seat 211 And the driving unit 22, after the driving wheel 221 of the driving unit 22 is rotated along its own axis by the power source, the workpiece 3 is rotated along its own axis, in the coating 12 201000654 step 15 The driving unit 22 is activated to drive the workpiece 3 to rotate. After a predetermined time, the plating material 4 is applied to all the inner surfaces of the workpiece 3 due to the continuous rotation of the workpiece 3, thereby obtaining an inner surface coating and having _ _ The tubular JL piece 3' of predetermined film thickness can be completely polished after the baking and sintering to complete the inner surface of the workpiece 3, and the plating cost can be greatly reduced at the same time, so that the plating cost can be greatly reduced. It is indeed possible to achieve the object of the present invention. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent change according to the scope of the invention and the description of the invention. And modifications: are still within the scope of the invention patent.
