A processing method for split lock cover and lock cover frame

Abstract

The invention discloses a split type lock cover, and discloses a processing method of the lock cover frame, wherein the processing method of the lock cover frame includes: step a, selecting a square aluminum ingot, extruding and forming a square frame strip, the square frame The position of the frame strip close to the bottom side of the square frame strip is provided with a convex strip that is parallel to the long side of the direction frame strip; step b, part of the convex strip is cut off, and a plurality of mutually disconnected convex edges are formed on the square frame strip; step c, bending the square frame strip to form a rounded rectangular frame, and the rounded corner of the rounded rectangular frame is located at the disconnection of the convex edge; step d, welding the head and tail of the original square frame strip on the rounded rectangular frame; In step e, anodizing treatment is performed on the outer surface of the entire rounded rectangular frame. The present invention reasonably designs the processing method of the lock cover frame, greatly shortens the manufacturing process of the lock cover, improves the production efficiency, and manufactures the lock cover frame with stable structure and beautiful appearance.

Description

technical field [0001] The invention relates to the field of locks, in particular to a split lock cover and a processing method for the lock cover frame. Background technique [0002] Lock covers such as existing smart locks and doorknob locks are all provided with lock covers, which are generally made of die-casting parts, and most of them are die-cast aluminum with low cost and high strength. In order to protect the lock cover, a protective layer or a decorative layer is usually applied on the lock cover by spraying paint, but the surface paint is easy to fall off, and the protection effect on the lock cover is poor, which greatly affects the service life of the lock. Moreover, the surface layer of the die-casting part is not smooth, and the appearance effect is poor, especially the frame part of the lock cover, which affects the sensory experience of the user. Some lock covers are also coated by electroplating, but the high cost of electroplating is not suitable for mass...

AI Technical Summary

Problems solved by technology

In order to protect the lock cover, a layer of protective or decorative layer is usually applied on the lock cover by spraying paint, but the surface paint is easy to fall off, and the protection effect on the lock cover is poor, which greatly affects the service life of the lock

Moreover, the surface of the die-casting parts is not smooth, and the appearance effect is poor, especially the frame part of the lock cover, which affects the user's sensory experience

Some lock covers are also coated by electroplating, but the cost of electroplating is high and it is not suitable for mass production processes

[0003] Moreover, the existing lock cover is usually made in one piece, and defects are prone to occur in the production process, the failure rate is high, easy to damage, and it is inconvenient to manufacture and install, and it is not easy to maintain the lock
