Pretreatment system before spraying of aluminum alloy workpieces

Abstract

The invention provides a pretreatment system for aluminum alloy workpieces before spraying, which includes a protective frame; a power box is fixed on the upper surface of the protective frame; the power box is fixed to a connecting shaft through a transmission pulley; A permeable pulley is provided below; the permeable pulley passes through the protective frame and the pretreatment box transversely, and its end surrounds the conveying wheel; the cross section of the pretreatment box is rectangular, made of gray cast iron, and It is arranged on the right side of the protective frame; the delivery pipe is connected above the water distribution plate; the delivery pipe passes through the pretreatment box; the partition is vertically arranged on the middle inner wall of the pretreatment box; The right side of the partition curtain is provided with a drying box; the drying box is welded and fixed on the upper inner wall of the right side of the pretreatment box, and two air pipes are connected above it; the structure of the present invention is relatively simple, and it is convenient to use and operate, satisfying It is suitable for popularization for the pretreatment requirements of aluminum alloy workpieces before spraying.

Description

technical field [0001] The invention relates to an aluminum alloy processing equipment, in particular to a pretreatment system for aluminum alloy workpieces before spraying. Background technique [0002] At present, before spraying the aluminum alloy, the aluminum alloy workpiece needs to be polished, oxidized, etc., and the surface should be rust-removed and oil-removed, and ensure that it is clean, dry and free of dirt, and the dust can be removed before paint spraying. Ensure that the workpiece is dry, so that the effect of spraying on its surface is better. [0003] Traditionally, the aluminum alloy workpiece is simply polished with artificial sandpaper before spraying, and then wiped with cotton cloth, which is not only inefficient, but also has poor effect. The quality after spraying cannot be effectively guaranteed, which is not conducive to market competition and cannot meet the requirements , it is necessary to use new equipment to solve the above problems.
