Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the utility model provides a convenient-to-convert stator and rotor sheet continuous punching die, which comprises a lower die holder 1 and a female die 9 fixedly installed at the upper end of the lower die holder 1, a slide box 2 is fixedly installed at the upper end of the female die 9, a box cover 18 is installed on the upper surface of the slide box 2 in a detachable manner, a stopper 10 is installed on the inner wall of the slide box 2 in a sliding manner, the stopper 10 is used for limiting a stator movable male die 11 and a rotor movable male die 12 to move up and down only and not to deviate in the moving process, the stator movable male die 11 and the rotor movable male die 12 are installed on one side of the stopper 10 far away from the inner wall of the slide box 2 in a sliding manner, the stator movable male die 11 and the rotor movable male die 12 are in sliding contact, a limit switch 8 is respectively arranged right above the stator movable male die 11 and the rotor movable male die 12, the, the outer wall surface of the stator movable male die 11, which is contacted with the rotor movable male die 12, is respectively provided with a semicircular groove 13, the two semicircular grooves 13 form a circular groove, a rotating shaft 4 is arranged on the central axis of the circular groove in a rolling manner, two ends of the rotating shaft 4 are respectively inserted on the front inner wall and the rear inner wall of the sliding box 2 in a rolling manner, two pairs of oscillating bars 14 are symmetrically arranged on the rotating shaft 4 positioned in the circular groove, each pair of oscillating bars 14 consists of two oscillating bars 14, and the included angle between the two oscillating bars 14 is 30 degrees, so that the oscillating bars 14 can ensure that the oscillating bars 14 push the stop blocks 15 to vertically move upwards until the stator movable male die 11 or the rotor movable male die 12 touches the limit switch 8, the oscillating bars 14 are not separated from the stop blocks 15 yet, the stator movable male die 11 and the rotor movable male die 12 can smoothly and reliably move upwards and downwards, the inner wall of the circular, when the swing rod 14 rotates along with the rotating shaft 4, the swing rod 14 touches the stop block 15, and the rotating motor 3 for driving the rotating shaft 4 to rotate is fixedly installed on the back of the sliding box 2.

As an alternative embodiment, a pad 17 is fixedly mounted on the lower surface of the box cover 18, and the limit switch 8 directly above the stator movable punch 11 is fixedly mounted on the lower surface of the pad 17, because the upper surfaces of the stator movable punch 11 and the rotor movable punch 12 are not on the same plane, generally the upper surface of the stator movable punch 11 is located below the upper surface of the rotor movable punch 12, and therefore, in order to ensure that the stator movable punch 11 smoothly hits the limit switch 8, the limit switch 8 needs to be moved downward by a certain distance.

The two stop blocks 15 are respectively positioned in the middle of the groove walls of the two semicircular grooves 13.

The outer part of the stop block 15 is sleeved with a sheath 16, and the sheath 16 is made of rubber, so that the design is used for protecting the stop block 15 and the connecting rod 6 on one hand and reducing noise generated in collision on the other hand.
