[0031] The support plate 26 is mounted on the punch die 25 , and the upper plane of the support plate 26 is flush with the upper plane of the turntable 15 .

[0032] Working principle and process:

[0033] The punch slide 17 reciprocates up and down once, the output shaft of the divider 27 drives the turntable 15 to rotate the angle between the two material dividing holes, and the push plate 29 reciprocates once.

[0034] The input shaft of the divider 27 rotates continuously and uninterruptedly, and the output shaft of the divider 27 rotates intermittently. The output shaft of the divider 27 rotates and stops once for each rotation of the input shaft of the divider 27. The output shaft rotates once for each rotation, and the angle of rotation of the output shaft is equal to the angle between the two material dividing holes on the rotating disk 15.

[0035] When the punch slider 17 moves downward, it drives the transmission rod 18, the joint bearing III 33, the connecting rod II 19, and the joint bearing IV 35 to move together. The joint bearing IV 35 drives the rocker 20 to swing back and forth around the small shaft V 38, and the guide rod 21 swings with the rocker 20. The guide rod 21 drives the cross slider 22 to move back and forth on the guide rod 21. At the same time, the cross slider 22 drives the eccentric wheel II 43 to rotate, and the eccentric wheel II 43 drives the transmission shaft 44, the coupling 47, and the input shaft of the divider 27 to rotate together.

[0036] The output shaft of the divider 27 drives the transition plate 28 and the turntable 15 to rotate together. Each time the punch slide 17 reciprocates up and down, the turntable 15 rotates an angle of a dividing hole. The dividing hole aligned with the barrel 13 rotates with a workpiece 14, and the next dividing hole rotates to the bottom of the barrel 13. The next workpiece 14 falls into the dividing hole of the turntable 15 and falls onto the lifting block 11. When the dividing hole with the workpiece 14 rotates to the top of the ball stud 24, the lower plane of the lifting block 11 hits the spherical surface of the ball stud 24, and the ball stud 24 lifts the lifting block 11 and the workpiece 14. The lower plane of the workpiece 14 is higher than the upper plane of the turntable 15. Then, the output shaft of the divider 27 stops rotating, while the input shaft of the divider 27 continues to rotate.

[0037] The input shaft of the divider 27 drives the eccentric wheel Ⅰ3 to rotate, and the eccentric wheel Ⅰ3 drives the hinge seat 5, the connecting plate 31, and the push plate 29 to reciprocate through the joint bearing Ⅱ9, the connecting rod Ⅰ8, and the joint bearing Ⅰ7. The arc on the push plate 29 pushes the workpiece 14 to the die 25, and then the punch of the punching machine falls to punch the workpiece 14 into shape.

[0038] At this point, the material separation, feeding and stamping of a workpiece 14 are completed.

[0039] The input shaft of the divider 27 continues to rotate, and the output shaft of the divider 27 rotates again, the material dividing hole on the turntable 15 turns away from the ball stud 24, and the lifting block 11 falls, waiting for the next workpiece 14 to fall onto the lifting block 11.

[0040] Repeat the above working process again and again.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
