Embodiment Construction

[0017] The present invention will be described in more detail below in conjunction with examples. However, the content of the embodiments is only an example and description of the present invention. Those skilled in the art can make various modifications or supplements to the described specific embodiments or replace them in similar ways, as long as they do not deviate from the principles of the invention. Conception or beyond the scope defined in the claims shall belong to the protection scope of the present invention.

[0018] 1. The composition of the pretreatment solution

[0019] 15 parts of sodium dodecylbenzenesulfonate, 12 parts of methanol, 2 parts of ethyl acetate, 0.5 parts of asiaticoside, 10 parts of sodium metasilicate and 52.5 parts of deionized water.

[0020] Two, the preparation method of pretreatment liquid is:

[0021] First add 15 parts of sodium dodecylbenzenesulfonate and 20 parts of deionized water to the container, and stir for 5 minutes; then slowly...

Abstract

The invention relates to the technical field of sheet metal part machining, in particular to a phosphating method of a clamp for sheet metal part machining. The method comprises the steps that oil stains on the surface of the clamp are wiped away, and then the clamp is washed with deionized water for 10 minutes and then scrubbed with ethyl alcohol for 5 minutes; the clamp is put into a pretreatment solution preheated to 50 DEG C to be soaked for 60 minutes; after being fished out, the clamp is washed with deionized water till the pH value of the deionized water for washing is restored to be neutral; the clamp is adjusted through a titanium salt table and then put into a phosphating solution for phosphating; after being fished out, the clamp is washed with deionized water till the pH value of the deionized water for washing is restored to be neutral, and then the clamp is dried; and the clamp is put into a constant-temperature furnace to be dried for 5 hours, and the temperature in the constant-temperature furnace is 55 DEG C. The formula and a preparation method of the pretreatment solution are reasonably designed, and therefore fast forming of a phosphating film on the surface of the clamp is achieved, the thickness is uniform, and then the repeated utilization degree of the clamp is increased.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to a phosphating treatment method for a fixture used for sheet metal processing. Background technique [0002] Fixtures for sheet metal processing, because the protective layer on the surface is gradually corroded with the increase in the number of uses, therefore, the fixture needs regular maintenance, and the protective layer is repaired by phosphating treatment (that is, the phosphating film is formed by phosphating) ). The existing phosphating treatment methods generally have defects such as incomplete phosphating treatment, which affects the reuse of the fixture, and in severe cases may lead to the complete scrapping of the fixture. Contents of the invention [0003] In view of the technical problems existing in the prior art, the object of the present invention is to provide a phosphating treatment method of a clamp for sheet metal processing. In order to ach...
