More retaining ring to be punched is stacked in feeding cylinder 3；
Feed block 4 is mounted on mounting rack 1 and is located at 3 lower section of feeding cylinder, and the retaining ring to be punched of bottom is fallen in feeding cylinder 3
In feed block 4,4 top surface of feed block is horizontally disposed, and 4 top surface of feed block and 3 bottom surface spacing of feeding cylinder are x, and the collar thickness is
Y, y≤x < 2y only accommodate a retaining ring to be punched between such feeding cylinder 3 and feed block 4；
Lower die 2 is mounted on mounting rack 1 and is located at 4 side of feed block；
Charging cylinder 5 is mounted on mounting rack 1, and the flexible path of charging 5 piston rod of cylinder is located at feed block 4 and feeding cylinder
Between 3, the flexible path ends of charging 5 piston rod of cylinder are located at the upper side of lower die 2, therefore charging 5 piston rod of cylinder can be with
It pushes on the retaining ring to be punched to lower die 2 between feeding cylinder 3 and feed block 4, after feeding the retraction of 5 piston rod of cylinder, feeding cylinder 3
Interior another retaining ring above the retaining ring of just punching press is fallen in feed block 4 in self gravitation effect, it is seen that by into
Material 5 piston rod of cylinder continuously stretches, and realizes the continuous feed of retaining ring；
Discharging cylinder 6 is mounted on mounting rack 1, and the flexible path ends of 6 piston rod of discharging cylinder are located at 2 top one of lower die
Side, therefore 6 piston rod of discharging cylinder can push in lower die 2 molding retaining ring.
The retaining ring punching press feeding structure that the present embodiment proposes, more retaining ring to be punched is placed into feeding cylinder 3, by
It is vertically arranged in feeding cylinder 3, the retaining ring positioned at bottommost is resisted against in feed block 4 under self gravitation effect, and due to charging
4 top surface of block and 3 bottom surface spacing of feeding cylinder are equal to the collar thickness, always with one wait rush between feed block 4 and feeding cylinder 3
The retaining ring of pressure, charging cylinder 5 push on the retaining ring to be punched to lower die 2 between feed block 4 and feeding cylinder 3, feed 5 piston of cylinder
After bar is withdrawn, there is a retaining ring to fall in feed block 4 in self gravitation effect, after retaining ring punch forming in lower die 2, unload
The piston rod movement of material cylinder 6 releases retaining ring after molding from lower die 2；From this repetition, charging cylinder 5 is continuously pushed wait rush
It presses on retaining ring to lower die 2, discharging cylinder 6 continuously pushes in lower die 2 molding retaining ring, realize the continuous punching of retaining ring, because
And the feeding and discharging of mechanization are realized using the above structure, ram efficiency is improved, labor intensity of workers is reduced.
It further include the first inductive probe to realize the feeding of automation, first inductive probe is mounted on feed block 4
On, first inductive probe is connect with charging 5 signal of cylinder, and the first inductive probe is to be punched in feed block 4 for incuding
Retaining ring, after the first inductive probe senses the retaining ring to be punched in feed block 4, the first inductive probe issues signal to feeding gas
Cylinder 5, to feed, 5 piston rod of cylinder is mobile, pushes on the retaining ring to be punched to lower die 2 in feed block 4.
It further include the second inductive probe to realize the discharging of automation, second inductive probe is mounted on lower die 2
On, second inductive probe is connect with 6 signal of discharging cylinder, and the second inductive probe has struck out in lower die 2 for incuding
The retaining ring of type, after retaining ring after the second inductive probe senses punch forming, the second inductive probe issues signal to discharging gas
Cylinder 6 pushes the molding retaining ring in lower die 2 so that 6 piston rod of discharging cylinder is mobile.
Retaining ring to be punched is placed in feeding cylinder 3, therefore, to assure that position it is accurate, position of the retaining ring in feeding cylinder 3
Precisely, it just can ensure that the position after retaining ring enters lower die 2 is accurate, and then ensure that punching press is accurate, else if retaining ring positioning is inaccurate,
It will lead to retaining ring punching press to destroy, further include locating rod 7, locating rod 7 is fixed on feeding cylinder 3 referring to Fig. 3 in the present embodiment
And it is parallel to the setting of 3 length direction of feeding cylinder, locating rod 7 protrudes from 3 inner wall of feeding cylinder, and retaining ring has opening, and retaining ring is placed into
After entering in feeding cylinder 3, the opening of retaining ring cooperates in locating rod 7, and otherwise retaining ring cannot be placed into feeding cylinder 3, gear
After circle enters in feeding cylinder 3, the projection of all retaining rings is all coincidence, thus retaining ring enters the position after lower die 2 accurate, punching press
Accurately.
Referring to Fig. 4, the position after lower die 2 is entered in order to ensure retaining ring is accurate, further includes four positioning pins 8 and four elasticity
Element, 2 top surface of lower die are set there are four mounting hole, the rounded arrangement of four mounting holes, and four elastic elements are pacified respectively
Mounted in four mounting hole bottoms, four positioning pins 8 are slidably mounted on respectively in four mounting holes, four positioning pins 8
Glide direction is parallel to the mounting hole depth direction, and four positioning pins 8 lean with four elastic elements respectively, pressing
Four positioning pins 8 can be such that four pressings of positioning pin 8 enter in mounting hole, and four positioning pins 8 are inclination close to rounded off inside
Face is resisted against on four positioning pins 8 after retaining ring enters lower die 2, on the outside of retaining ring, to be positioned to retaining ring, anti-Sealing shield ring into
Position deviates when entering lower die 2；Being also possible to four positioning pins 8 close to rounded off inside is inclined surface, when retaining ring enters lower die 2
Afterwards, it is resisted against on four positioning pins 8 on the inside of retaining ring, to position to retaining ring, anti-Sealing shield ring position when entering lower die 2 occurs inclined
Difference；When discharging cylinder 6 pushes molding retaining ring, positioning pin 8 is subdued by retaining ring, so that retaining ring can be pushed away.
