Problems solved by technology

[0002] The roughness of the existing cable fittings is uneven, which makes the distribution of stress points of the fittings uneven. After fixing, the cables are easy to loosen, and the fittings are easy to rust, and the fatigue resistance of the fittings is also poor, resulting in a short service life. A new way to solve the above problems

Embodiment Construction

[0012] A metalware sandblasting process,

[0013] (1) Preparation before sandblasting: select relevant sandblasting equipment and corresponding sand molds according to the instruction card;

[0014] (2) Sandblasting test: pre-spraying test, open the compressed air valve and water valve, check whether there is air leakage or water leakage, and test whether the spray gun can blast sand normally;

[0015] (3) Sandblasting: Rotate the metalware to be sandblasted on the material tray at the position to be sandblasted, close the door of the sandblasting machine, and perform sandblasting;

[0016] (4) Cleaning: Clean the goldware after sandblasting, clean it with clean water, soak it in the anti-rust solution for 5-6 minutes, and dry it with compressed air;

[0017] (5) Poor inspection: check the sandblasting quality of the fittings, and rework unqualified products.

[0018] In this example, the antirust agent is a water-based antirust agent, and SD-405 environment-friendly antirus...

Abstract

The invention discloses a sand blasting technology for hardware. The technology comprises the following steps: (1) preparing before sand blasting, namely, selecting related sand blasting devices and corresponding sand molds based on an instruction card; (2) sand blasting test, namely, performing pre-blasting test; opening a compressed air valve and a water valve; detecting whether air and water are leaked; and testing whether a blasting gun is capable of normally blasting sand; (3) sand blasting, namely, rotating the hardware to be subjected to sand blasting on a material plate at a position for sand blasting; closing a door of a sand blasting machine; and blasting sand; (4) washing, namely, washing the sand blasted hardware through clean water; soaking in an antirust solution for 5-6min;and blowing to dry through compressed air; and (5) inspecting, namely, inspecting the sand blasting quality of the hardware; and reworking unqualified products. According to the sand blasting technology for the hardware, the processes are simple and are reasonably and coordinately arranged; the roughness and uniformity of the hardware can be improved; the stressing points of the hardware are uniform; the corrosion resistance of the hardware is improved; the fatigue resistance of the hardware is high; and the service life of the hardware is long.

Description

technical field [0001] The invention relates to a sandblasting process, in particular to a metalware sandblasting process. Background technique [0002] The roughness of the existing cable fittings is uneven, which makes the distribution of the stress points of the fittings uneven. After fixing, the cables are easy to loosen, and the fittings are easy to rust, and the fatigue resistance of the fittings is also poor, resulting in a short service life. A new way to solve the above problems.
