Embodiment Construction

[0044]The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0045] Example. A method for partial electroplating of lead-indium alloy on a petal-shaped rotor, comprising the following steps: Figure 1-13 shown, including the following steps:

[0046] (1) Degreasing with organic solvent;

[0047] (2) Protection: use insulating tape, tape or tooling for protection;

[0048] (3) Mounting and hanging:

[0049] 3.1 Before electroplating, use electroplating tooling to hang the petal-shaped rotor 11 workpiece. The electroplating tooling is composed of hanger 1, hexagon socket head bolt 2, clamp 3 and plug 5. When installing and hanging, turn the electroplated end face 7 of the workpiece downward, first block the inner hole 8 on the electroplated end face 7 of the workpiece with a plug 5, and clamp the clamp 3 at the position of the petal shape 4 on the outer surf...

Abstract

The invention discloses a method for partially electroplating lead-indium alloys on petal-shaped rotors. The method comprises the following steps: (1) deoiling through an organic solvent; (2) protecting by using insulated rubber tapes, adhesive tapes or tools; and (3) hanging, wherein the step (3) of hanging comprises the following substeps: a substep 3.1 of hanging petal-shaped rotor (11) workpieces by using electroplating tools and then moving the electroplating tools and the workpieces through hoisting rods (10) for electroplating; and a substep 3.2 of hanging the electroplated and dried workpieces by using oil heating tools before oil heating treatment and then placing the oil heating tools and the workpieces into a lubricating oil heat treatment tank for heat treatment through hoisting handles (13). The method for partially electroplating the lead-indium alloys on the petal-shaped rotors has the beneficial effects that the problem that the workpieces are obliquely hung or separated when partially electroplating the lead-indium alloys on the existing petal-shaped rotors is overcome, a method for partially electroplating the lead-indium alloys is provided and is capable of obtaining petal-shaped rotor plating layers which are consistent in color and are uniform and integral, and the method is safe and reliable.

Description

technical field [0001] The invention relates to a method for partial electroplating of lead-indium alloy, in particular to a method for partial electroplating of lead-indium alloy on a petal-shaped rotor. Background technique [0002] At present, lead-indium alloy is electroplated on the end face of the petal-shaped rotor of cast copper alloy (such as: ZQSb3.5-20) material to form a coating with a color of light gray to gray, and the crystallization should be uniform and complete. With the continuous development of science and technology, A uniformly crystalline coating has always been expected in the field of modern technology. According to customer requirements, the color of the lead-indium alloy coating on the workpiece should be light gray to gray, the crystallization should be uniform, the coating should be complete, and the coating should not fall off after the subsequent running-in test. Therefore, , When electroplating lead-indium alloys, the selection of the appropr...
