Abstract

Disclosed is a method for manufacturing a lock cylinder shell of a blade mortise lock. The lock cylinder shell of the blade mortise lock is used for containing a lock cylinder and a locking column, and comprises a beam and a casing pipe for containing the lock cylinder. A through groove is formed in the casing pipe, and the beam is provided with a curved surface corresponding to the surface of the casing pipe. The method comprises the steps that A, a forming pipe is cut according to the length of the lock cylinder, and made into a casing pipe blank; B, the through groove is formed in the casing pipe blank, and used for containing the locking column, and the casing pipe is formed; C, the curved surface capable of being closely attached to the outer surface of the casing pipe is machined on a blank of the beam according to the shape of the outer surface of the casing pipe; D, the blank of the beam is cut according to the length of the lock cylinder, and the beam is manufactured; E, the curved surface of the beam is fixed to the outer surface of the casing pipe and covers the through groove. In the method for manufacturing the lock cylinder shell of the blade mortise lock, hole drilling or mounting cavity forming is not needed.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a method for manufacturing a lock cylinder shell of a blade mortise lock. Background technique [0002] The lock cylinder is an important component of the door lock, which plays the role of opening and closing the door lock. The structure of the lock cylinder of the existing anti-theft door lock includes a lock cylinder shell, the lock cylinder shell is "gourd-shaped", and several marble holes are arranged in the lock cylinder shell, and there are graded marbles in the pinhole holes. A key slot is arranged on the axial direction of the shell, and the ends of the pins extend into the key slots, and under the action of spring force, the ends of the pins press against the bottom of the key slots. When the key compatible with the level difference of pins in the lock core is inserted from the socket of the key slot, the key presses the ends of the pins, and the pins are displaced in th...
