Embodiment Construction

[0013] As shown in Figures 2 and 3, the specific embodiment of the present invention is a key for a magnetic lock, which is composed of a flat iron blank 1 and a plastic shell 2 wrapped outside the iron blank 1. The shape of the blank is wide at the top and narrow at the bottom, the upper part is rectangular, and the lower part is thin rod-shaped. As a reinforcement of the key, the plastic shell 2 forms the insertion part 21 and the grip part 22 of the key. The ring forms a plurality of magnetic bullet holes 23 for accommodating the magnetic bullets 3, and the front end of the insertion part 22 is covered with a magnetically conductive copper jacket 4. The axial length of the copper jacket 4 is greater than that of the uppermost magnetic bullet hole 23 on the insertion part 22. The distance from the front end of the portion 22 can just in time all the magnetic bullet holes 23 be closed, because the purpose of the copper overcoat 4 is to protect the magnetic bullet 3.

Abstract

The invention relates to a key for magnetic lock and the manufacturing process. The key comprises metal reinforced component and plastic shell covering said metal reinforced component. Inserting part and handling part of key are formed in plastic shell. Multiple magnetic bullet holes accommodating magnetic bullets are formed round the front end of inserting part and magnetic conductive jacket mated with the outer diameter of magnetic bullet hole suitably is set at the front of inserting part. The manufacturing process of magnetic lock is that the metal reinforced component is formed by a single stamping at first, then the plastic shell is used to cover the metal reinforced component, then magnetic bullet hole is formed at the front end of inserting part of plastic shell by drilling, and then magnetic bullets are set in magnetic bullet holes, finally the jacket is set at the front end of inserting part so as to seal the magnetic bullet hole. The key in invention is provided with high noncorrosibility, beautiful figure. The process is provided with few procedures and low producing cost. The metal reinforced component in key is machined by stamping and the plastic shell is formed by die casting or injection molding method. The dimension stability of produced key is ensured and it is suitable for mass production.

Description

technical field [0001] The invention relates to a lock, in particular to a magnetic lock key and a production process thereof. Background technique [0002] As shown in Figure 1, the key of the existing magnetic lock has an insertion part that can be inserted and removed in the magnetic lock and a grip part arranged at the tail end of the insertion part. The insertion part and the grip part of the key are made of metal materials. The front end of the insertion part is provided with a plurality of magnetic bullet holes for accommodating the magnetic bullets along the circumference, and a magnetic conductive copper jacket for protecting the magnetic bullets is provided on the outer ring of the magnetic bullet holes at the front end of the insertion part. The production process of this key is to punch out the inserting part and the holding part respectively, after the inserting part is machined to select the size, then the two are welded together, and the surface is chrome-plat...
