Preparation method of aluminum alloy lock panel

Abstract

The invention belongs to the field of locks and provides a preparation method of an aluminum alloy lock panel. The preparation method comprises the following steps of (1) carrying out forging on an aluminum alloy panel material and an aluminum alloy rivet at 500-520 DEG C to integrate the aluminum alloy panel material and the aluminum alloy rivet; (2) carrying out heat treatment on a forged aluminum alloy lock panel to reach HB37, removing a marginal material of the product subjected to heat treatment, and then carrying out stamping, drilling and tapping according to the positions of a handleand a rotary knob; (3) manually polishing the cut surface of the side face of the lock panel, and then carrying out vibrating, water grinding and polishing on the surface of the lock panel for 2-4 h;and (4) carrying out dry polishing, specifically, carrying out coarse polishing through abrasive paper of 20-40 meshes and a polishing agent for 5-7 h, and then carrying out precision polishing through abrasive paper of 80-100 meshes for 3-5 h. According to the preparation method, the aluminum alloy forging mode is adopted for the lock panel, further post-treatment is carried out on the manufactured aluminum alloy lock panel product, and the manufactured aluminum alloy lock panel and connecting column have the advantages of being high in hardness, not prone to color fading, anti-static and thelike.

Description

technical field [0001] The invention relates to the field of locks, in particular to a method for preparing a lock panel. Background technique [0002] At present, most of the lock panels on the market are made of zinc alloy, which is made of zinc alloy die-casting, electroplating, or surface spraying, etc. The lock panels manufactured by this process have surface coatings that are easy to fall off and have a single color. It looks very ugly, not anti-static, high cost and other shortcomings and deficiencies. [0003] Using aluminum alloy as a panel has been developed before, but all of them failed. One type uses aluminum die-casting, the product has no strength, the surface cannot be anodized, and it can only be electroplated or oil sprayed. The effect is not as good as that of zinc alloy, and there is no market for a while. In the second type, some people have also forged the lock handle, but they can't make a better surface effect.
