Description

There are known stamps-combines of sequential action for the manufacture of products from a ribbon and wire by stamping one or several parts from a ribbon and assembling them in one of the positions of a stamp with a wire rod.

The described stamp combine is intended for the manufacture of parts of portfolio locks and, in contrast to the known stamping combines, is equipped with a bending-cutting matrix that is movable from an eccentric, interacting with the sleeve through which the wire is fed, cuts the measured wire blanks, interacts with the punch, and bends these wire blanks in the brackets and insert them into the hole-1i, punched in the tape. The movable matrix is located in the assembly position of the product under the stamped belt and serves as a support for riveting the legs of the staples on the tape. In FIG. 1 is a schematic diagram of the die-stamp described; in fig. 2 is a schematic representation of a stamp combine, side view (with a partial section); in fig. 3 - the same plan view; in fig. 4 - section aa on f | i. 3; in fig. 5 is a view along arrow L of FIG. 3

The stamp-combine described has two automatic feeds that are driven by means of a slider: a wedge-roller for supplying a stamped tape and a wedge-knife for supplying a stamped wire from which the product is made.

Through the carriage / and 2 roller feed into the die-combine, tape 3 is filled. During operation of the die-combine, for the first working stroke of the slider 4, the tape 3 is stamped by the punch 5, the KpOMKit is cut down by the punch 6, the frame is formed from the tape by the punch 7 and punctured holes 8 punch 9. During the second stroke of the slide 4 wedges 10 through the rollers 11 feed it, the carriage / belt 3 is mixed by the corresponding feed step set with the help of adjuster No. 142622-2iroro 72, TH in the die-combine combine the same operations what and

at the first working stroke of the slider 4. The wedge 10 is rigidly fixed on eMneiplpte J3, the upper end of the half-full 4 is movably attached to the hinge, and all the steps that produce the first and second working strokes are repeated during the working stroke of the slider from the wire blank, install the clamp bracket and insert 8 tape 5 and the rivet legs of the bracket. To carry out these operations, the stamp combine is equipped with a matrix 15, a movable reciprocating in a vertical plane with the help of an eccentric 16, which is rigidly fixed on the rotary axis 17. On the axle / 7, the forked lever 18 is pivotally attached by means of a finger 19 to the lower the end of the slider 4, interacting with the wedge 20, which is rigidly connected with the upper plate 13.

The coil 21 of the wire is mounted on the coil 22, which freely rotates on the axis 23. The free end of the wire is threaded through the correct rollers 24 into the feed carriage 25 and then the wire is passed through the sleeve 26 to the movable matrix 75. Lastly, I interact with the sleeve 26 to cut off the dimensional wire blanks - The feed carriage 25 has a knife 28 pivotally fixed on the axis 27, which is constantly pressed to the wire by means of the spring 29. With the working stroke of the plate / (and moving it downward the lower end of the slide 4 through the lever / 5 and the eccentric 16 will force the matrix J5 up and interact with the punch 30 made in the form of a cantilever (finger) that bends the wire blank into the clip 14 on the matrix 15. In this case, the legs of the bracket supported by the matrix 15 are passed through the holes 8 of the tape 3 and riveted by the gun 31. 11 idle the slider 4 and the movement of the top plate 13 upward the blade 32, acting on the head of the earring 33, turns it on the axis 34 and moves the carriage 25 together with the wire wedged in it by the knife 28. The feed pitch is adjustable bolt 35. The carriage 25 returns to its original position by using the spring 36. The matrix 15 is returned to its original position by means of the spring 37 and the wedge 20. During the fourth working stroke of the slide 4, except for repeating all operations performed in the combine harvester for three strokes, the tape 3 is being rolled, with a clip attached to it on the die matrix, and Paunson 38 the finished product is cut from the tape to a "dip." Further, the cycle of all described operations is repeated.

Subject invention

A sequential action shgamp for making articles of tape and wire, characterized in that, for the purpose of manufacturing, for example, parts of the portfolio locks, the chip is provided with a lifting matrix, for example, by means of an eccentric, which interacts with the sleeve through which the wire is fed , cutting off dimensional wire blanks, interacting with a punch made in the form of a cantilever protrusion (finger), bends the wire blanks into the brackets and inserts the brackets into the holes punched in the tape, and serves as also support for staples when ripping them in tape.
