Surface treatment device for aluminum magnesium alloy die castings

Abstract

The invention discloses a surface treatment device for aluminum magnesium alloy die castings, and in particular relates to the technical field of surface treatment. The surface treatment device comprises a rack, a through groove is formed in the top end of the rack, and a base is welded on the edge, close to the through groove, of the rack. A cross beam is arranged at the position, close to the top end, of the inner side of the rack, and the cross beam is welded with rack. A working platform is arranged on the upper surface of the cross beam, and a wire drawing mechanism is arranged on the upper surface of the base. The wire drawing mechanism comprises a group of sliding rods transversely inserted into the base, and transverse transplanting cylinders are fixedly arranged on the outer surfaces of the sliding rods in a sleeving mode. Pressing plates are erected at the two ends in the transverse direction of the top end of the working platform, and pressing cylinders are fixedly arrangedat the two ends in the radial direction of the upper surfaces of the pressing plates through bolts. Compared with the prior art, the surface treatment device is not limited by dies and ensures that the wire drawing area is not limited, so that the wire drawing process of the aluminum magnesium alloy die castings is stable, and the wire drawing effect is ensured.

Description

technical field [0001] The invention relates to the technical field of surface treatment, more specifically, the utility model relates to a surface treatment device for an aluminum-magnesium alloy die casting. Background technique [0002] The main element of aluminum-magnesium alloy is aluminum. The aluminum alloy with magnesium as the main additive element has excellent processing performance, good corrosion resistance, high toughness, no deformation after processing, and excellent oxidation effect. It is widely used in demanding There are various industrial structural parts with certain strength and high corrosion resistance. [0003] Aluminum-magnesium alloy die-casting parts need certain surface treatment to enhance their decoration before product processing. Among them, aluminum-magnesium alloy surface drawing process is a commonly used surface treatment technology according to product decoration needs. [0004] The wire drawing equipment in the prior art adopts the h...

AI Technical Summary

Problems solved by technology

[0004] The wire drawing equipment in the prior art adopts the high-speed rotation of the abrasive belt and presses down the abrasive belt to make the abrasive belt draw on the surface to be worked. In this case, the workpiece is usually fixed on the mold to prevent the relative movement of the workpiece, while the aluminum-magnesium alloy Die-casting plates are usually large in size and the drawing area of ​​the wire-drawing equipment is limited due to the limited size of the mold, which is not conducive to the stability of the drawing process, and thus cannot be applied to the drawing of aluminum-magnesium alloy die-casting plates, which brings limitations in use
