Lock cylinder key hole slot broaching process

Abstract

The invention discloses a lock cylinder key hole slot broaching process. The lock cylinder key hole slot broaching process specifically comprises the following steps that 1, the appearance of a lock cylinder part is turned on a machine tool, and a center hole is drilled in the end face of the head of the lock cylinder part; 2, the drilled lock cylinder part is placed into an axial through hole exposed out of a feeding station of a concave notch through a feeding machine; 3, a lower die rotating platform is set to rotate by an angle and move forwards by a station, so that the lock cylinder partwhich is just fed enters the position below a guide hole with the minimum caliber, a center hole of the lock cylinder part is aligned with the minimum guide hole, meanwhile, a discharging station hole moves forwards to form a feeding station hole, and the station at the guide hole with the maximum caliber moves forwards to a discharging station; and 4, the feeding machine continues to put a nextlock cylinder part into the axial through hole located in the feeding station, meanwhile, an ejection mechanism is arranged to eject the machined lock cylinder part located in the discharging stationout of the discharging station, preparation is made for feeding of the next procedure, a cold punching technology is adopted, the machining precision is high, and automatic production can be achieved.

Description

technical field [0001] The invention relates to the technical field of lock processing, in particular to a key hole drawing groove process of a lock cylinder. Background technique [0002] The keyhole is located in the middle of the lock cylinder, so it cannot be processed with a broach. The existing keyhole of the lock cylinder usually adopts the method of thermal processing, which has low precision and large environmental pollution. Due to the high temperature requirements, automatic production cannot be realized. , so it is necessary to provide a new grooving process for processing. SUMMARY OF THE INVENTION [0003] Purpose of the invention: In order to solve the deficiencies in the background technology, the present invention discloses the keyhole slot drawing process of the lock cylinder. [0004] Technical solution: the keyhole slot drawing process of the lock cylinder, which specifically includes the following steps: [0005] Step 1: Carve out the shape of the loc...
