Lock core

Abstract

The invention discloses a lock core which comprises a lock core buffer strip, a plurality of lock core sheets, a plurality of ball-hole sheets and a plurality of connecting pins. The lock core buffer strip is positioned at one end of the lock core; the ball-hole sheets and the lock core sheets are arranged alternately and laminated into the shape of the lock core required. The lock core buffer strip, the lock core sheets and the ball-hole sheets are connected as a whole by the connecting pins or by a welding method. The lock core of the invention reaches use requirements in a way that a plurality of sheet metal parts are combined into the shape of the lock core required. As the laminated lock core is combined by using the sheet metal parts with high precision and guaranteed size, the lock core combined has precise size, fast processing speed and low cost. The diameter of the lock core is not large commonly, and the sheet metal parts of the lock core can utilize the rim charge of stainless steels, copper plates or iron plates as raw material, thus saving energy resources and meeting the requirements of environmental protection.

Description

technical field [0001] The invention relates to a lock cylinder, in particular to a laminated lock cylinder. Background technique [0002] At present, in the production process of the existing lock cylinders, most of them are made of copper rods through deep processing. The disadvantages of this production method are that the processing is cumbersome, the use of too many equipment, the process is complicated, the precision is difficult to control, and the cost is high. The second is to use die-casting zinc alloy, die-casting aluminum alloy and die-casting magnesium alloy for direct molding. The disadvantages are poor strength, easy oxidation, not durable, and the products need electroplating, which is not environmentally friendly. For this reason, people are looking for new methods to solve the above-mentioned shortcoming. Contents of the invention [0003] The purpose of the present invention is to provide a lock cylinder with precise size, fast processing speed, low cos...
