Abstract

The invention relates to the processing of metals by pressure, in particular to equipment for the manufacture of parts from a tape. The purpose of the invention is to reduce the size of the machine. The machine contains disks / D / 6 and 15. The latter are connected with the drive 1. D 6 bears the punch / P / 7, and D 15 carries the die / M / 17 and the puller 16. The machine also contains a fixed cutting knife 18 and rollers 21 and 22 of the feed of the belt 24. The D 6 has a constant rotational speed, with the D 15 a variable due to the coupling of the D 15 with the drive through the eccentric gears 12 and 13. The belt 24 is fed between P 7 and M 17 at the moment of their greatest divergence by the difference in rotational speeds D 6 and D 15. A piece of workpiece 25 M 17 and a knife 18 occurs, and M 17 begins to catch up with P 7. At the moment of their meeting, an incision occurs and bending of the elements of the workpiece 25. Then P 7 begins to move away from M 17 and move closer to the puller 16. The part is removed. 3 il.

(57) The invention relates to the processing of metals by pressure, and in particular to equipment for the manufacture of parts from a tape. The purpose of the invention is to reduce the dimensions of the machine. The machine contains disks (D) 6 and 15. Others are associated with drive 1. D 6 bears the punch (P)

D 6 has a constant rotational speed, and D 15 - variable due to the connection D 15 driven through eccentric gears 12 and 13. Tape 24 is fed between P 7 and M 17 at the moment of their greatest discrepancy due to the difference in speeds of lying D 6 and D 15. There is a piece of workpiece 25 M 17 and a knife 18, and LD 17 It begins to catch up to P 7. At the moment of their meeting, there is a nadrzka and bending of the elements of the stump 25. Then P 7 begins to move away from M 17 and approach , Stripper 16. There will eat details. 3 il.

The invention relates to the processing of metals by pressure, in particular to equipment for the manufacture of parts from a tape.

The purpose of the invention is to reduce the size of the machine.

FIG. I shows the kinematic scheme and the proposed automaton; FIG. 2 - - the scheme of the position of the workpiece after felling; in fig. 3 - detail (square button).

The machine contains an electric motor I, on the shaft of which pulley 2 is fixed, Pulley 2 is connected to a driven pulley 4 mounted on shaft 5 by a V-shaped belt 3. A shaft with a punch 7, a lester 8 and H1 stern 9 with helical teeth are mounted on the shaft 5. The gear 8 engages with the gear 10 mounted on the shaft II. Eqster is also attached to shaft II (trichnaya on gear 12, which engages with eccentric gear 13 mounted on hollow shaft 14. At the other end of hollow shaft 14, there is a disk 15 with a puller 16 freely passing through punch holder, and a die 17 having a cutting edge, with which it performs the functions of a movable cutting knife and interacts with a fixed knife 18. Screw gear 9 engages with gear 19 fixed on the shaft 20. A shaped roll is fixed on the free end of the shaft 20 21 interacting with rollers 22 of the material feed. A fixed segment blanket 23 is installed along the generator disc 15. The material (tape) is indicated by 24, and the blank is indicated by 25.

The machine works as follows.

When the motor 1 is turned on, the rotational movement is transmitted through a wedge-time transmission 2-4 to the shaft 5. Herewith, gears 9 and 19 set in motion the shaft 20 with the profiled roller 21.

The profiled roller 21, the interaction with the roller 22, in particular the MOMeiiT impresses the feeding of the belt 24 against the disc 6. The F3 turn, gears 8 and 10 are driven by the shaft II. At the same time, an eccentric pair 12 and 13 transmits a wrench variable movement of hollow shaft 14 with disk 15. At the moment of lagging disk 15 away from disk 6, i.e., when the punch 7 is completely removed from the matrix 17, the tape 24 is fed, and then cutting the edge of the die 17, interacting with the stationary knife 18, cuts the workpiece 25. As the disks b and 15 turn, the matrix 17 and the punch 7 come together through 180 °, and punch the hole and then disperse. The button, striking the puller 16, is released from the punch 7 and is ejected into the container under the action of centrifugal force. The fit of the workpiece 25 to the matrix 17 at the time of the segments is due to the friction of it about the blade 18 and the disk b.

The implementation of the invention will reduce the size of the machine due to a more compact installation of the shaft with the tools.
