Split type lock cover and processing method of lock cover frame of split type lock cover

Abstract

The invention discloses a split type lock cover, and discloses a processing method of a lock cover frame of the split type lock cover. The processing method of the lock cover frame comprises the stepsthat step a, a square aluminum ingot is selected and extruded and molded to form square frame bars, and convex bars parallel to the long sides of the square frame bars are arranged at the positions,near the bottom sides of the square frame bars, of the square frame bars; step b, the partial convex bars are removed, and a plurality of disconnected convex edges are formed on the square frame bars;step c, the square frame bars are bent and molded to form rounded rectangular frames, and the rounded corners of the rounded rectangular frames are located at the disconnection of the convex edges; step d, heads and tails of the original square frame bars on the rounded rectangular frames are welded; and step e, anodic oxidation treatment is carried out on the outer surfaces of the whole roundedrectangular frames. The processing method of the lock cover frame is reasonably designed, the manufacturing process of the lock cover is greatly shortened, the production efficiency is improved, and the stable and beautiful lock cover frame is prepared.

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
