Embodiment Construction

[0034] All features disclosed in this specification, or steps in all methods or processes disclosed, can be combined in any way, except for mutually exclusive features and / or steps.

[0035] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0036] According to the accuracy of the electroplating position of the strip required by the metal parts, the coil is first coated and punched, and then the film in the relevant electroplating area is discarded, and finally the strip is accurately electroplated, and finally punched and cut. The present invention changes the traditional complete electroplating of material strips into partial electroplating of material strips, which not only solves...

Abstract

The invention discloses a precise machining process for local tin-plating of metal parts. According to flexible material pure-nickel materials required by the parts, coiled materials are subjected to coating and punching; membranes on a position requiring electroplating are subjected to waste discharge by a waste discharge machine; a protective membrane on an electroplating material strip is discharged while electroplating; the membrane is punched into the material strip and is rolled, and then is cleaned; a blanking material is cut off by utilizing an automatic cut-off machine to complete automatic packaging. According to the precise machining process, the precision of coating and punching is utilized firstly, the accuracy of the processes of firstly coating and punching and then electroplating is improved, the production efficiency is improved, the yield of the product is improved, and the wastes of manpower cost and material cost are reduced.

Description

technical field [0001] The invention relates to a local precision tin plating process of metal parts. Background technique [0002] At present, customers of metal parts often require the overall surface of the product to be tinned, and there is no requirement to control the boundary size of tinning. Therefore, the commonly used tinning only needs to solve the problem of tinning thickness, and the traditional electroplating process can meet customer requirements. [0003] However, this time the customer requested that the metal products require partial tin plating, and the border size of tin plating should be controlled, and the control size requirements should be strict (±0.1mm), such as figure 1 shown. [0004] There are two options for partial tin plating using the existing process: [0005] The first solution: stamping to complete the product structure first, and then partially tinning the surface of the product. This solution needs to cover the surface that does not n...
