Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The utility model provides a punching die for lock cylinder processing as shown in figures 1-3, which comprises a lower die holder 1 and an upper die holder 2, wherein the upper die holder 2 is positioned at the top of the lower die holder 1, a lock cylinder clamp 3 is fixedly arranged at the top of the lower die holder 1, an adjustable punching mechanism 4 is rotatably arranged at the bottom of the upper die holder 2, and after a turntable 41 in the adjustable punching mechanism 4 is stirred, a plurality of punches 43 are driven to rotate by taking a rotating shaft 42 as an axis, so that the positions of the plurality of punches 43 are adjusted, and the punches 43 with different specifications are switched to be right above the lock cylinder.

It should be further noted that the lock cylinder clamp 3 belongs to the technology that has been disclosed in the prior art, and does not belong to the necessary technical features of the present application, so that the present application does not describe the specific structure thereof again.

As shown in fig. 2 and 3, the adjustable punching mechanism 4 includes a dial 41, a rotating shaft 42, a punch 43, a positioning hole 44, a positioning bolt 45, a return spring 46, and a pull ring 47.

More specifically, the turntable 41 is located at the bottom of the upper die holder 2, the rotating shaft 42 is fixedly arranged at the center of the top of the turntable 41, and penetrates through the upper die holder 2 and is rotatably connected with the upper die holder 2 through a bearing, the punches 43 and the positioning holes 44 are provided in plural, the punches 43 are uniformly and fixedly arranged at the bottom of the turntable 41 in an annular shape, the positioning holes 44 are uniformly and circularly arranged at the bottom of the turntable 41, the positioning holes 44 are respectively located at the inner sides of the punches 43, the positioning bolt 45 penetrates through the upper die holder 2 and extends to the inner side of any one positioning hole 44, the reset spring 46 is sleeved and arranged at the outer side of the positioning bolt 45, the top end of the reset spring is fixedly connected with the positioning bolt 45, the bottom end of the reset spring is fixedly connected with the upper die holder 2, and the pull ring 47 is fixedly arranged at the top of the positioning bolt 45, so that when the punching specification needs to be changed, the technician can upwards stimulate the pull ring 47, then rotates the carousel 41, and then makes the carousel 41 drive a plurality of drifts 43 rotatory, moves the drift 43 that accords with current specification to lock core anchor clamps 3 directly over after, loosens the pull ring 47, and under the pulling of reset spring 46, the positioning bolt 45 enters into the locating hole 44 again at this moment and fixes a position the carousel 41.
