SU755383A1 - Multiposition die for producing hollow articles - Google Patents

Description

The invention relates to the field of sheet punching, in particular to devices for the manufacture of hollow parts.

Known multi-stamp for the manufacture of hollow parts, for example, cans for autosiphones, containing a rotary unit with lower matrices and equipped with a stripper-limiters [1]. However, such a stamp does not provide for the molding of high-quality products, since the shaping dies are located in two blocks, one of which is rotatable and therefore, because of the inaccuracy of fixing the dies along the axis, the neck of the ampoules is eccentric relative to its body.

Also known is a multi-position stamp for the manufacture of hollow parts, containing a rotary turret disk with spaced sockets for mounting parts, mounted on a fixed table under the sockets of the die disk, and also mounted on the press slide coaxially to the punches and spacer pullers located above the turret disk [ 2].

The disadvantage of this stamp is the impossibility of forming tubular products without a collar and protruding elements.

The aim of the invention is to provide the possibility of the formation of tubular ₅ products without collar and protruding elements, as well as improving the quality of the formed products.

This goal is achieved by the fact that the stamp is provided with an additional movable plate in which pullers are located parallel to the fixed plate from the side opposite to the punches, and

rigidly connected with the ram press.

FIG. 1 shows a stamp, section; in fig. 2 - section A — A in FIG. one; in fig. 3 shows a diagram of the technological transitions ¹⁵ rows.

The stamp has a plate 1 fixedly mounted on a bed of a horizontal press and a movable plate 2 which is attached to the slide 3 of the press and together with it co 20 performs a reciprocating movement.

On the plate 1 along the circumference are placed the retaining matrix 4 for sequential stamping - crimping the neck of the but3

There are five billets and an axis of rotation 6 of the revolver disk 7 located between plates 1 and 2. The revolving disk is equipped with grippers 8. To rotate the revolving disk at a certain angle at the other end of the axis 6 is fixed ratchet wheel 9.

On the slab 2 of the same circumference as on the slab 1, the punches 10 crimp the bottom of the workpiece, the number of which corresponds to the number of transitions required for the complete shaping of parts, and the ejector 11.

With the plate 2 is rigidly connected to the guide columns 12 Additional movable plate 13 mounted for nepod- ¹⁵ Vision plate 1 and provided with scrapers 14, 15 zatalkivatelem workpieces gripper 8 revolving disc 7, which are also mounted on the circumferential placement of punches and matrices 4 10. 20

The device works as follows.

The blanks, for example, from the tray enter the receiver 5. At each stroke of the slide 3 to the right, the pusher 15 sets the blank into the grip 8 of the turret disc 7, which, turning from the ratchet wheel 9, transfers the blank to the first crimping position. When the slider moves to the left, the punch 10 produces a billet from the gripper 8 to the matrix 4 — a _{slip of зат0} is formed, i.e., two-sided crimping by the matrix 4 and the punch 10. Then the slider returns to its original position, i.e. moves to the right, while the next billet from the receiver 5 is set to the next gripper 8 of the turret disk 7, and “the semi-finished product from the first crimping matrix is removed by the puller 14 and transferred to the gripping of the turret disk, which transfers the billet to the next machining position.

Next cycle of the stamp is repeated. At the last position, the product from the grip of the turret disk by the ejector 11 is issued from the press.

The proposed multi-stamp for the manufacture of hollow parts provides the possibility of forming tubular products without collar and protruding elements, as well as improving the quality of the formed products.

Claims (1)

Claim Multi-position stamp for the manufacture of hollow parts, containing dies mounted on a fixed plate and a rotary turret disk with slots for mounting parts located around its circumference, as well as punches fixed on the press slide coaxially with dies and a turret disk, and parts strippers, characterized in that in order to ensure the possibility of forming tubular products without a collar and protruding elements, as well as improving the quality of the formed products, it is equipped with an additional movable plate, located parallel to the fixed plate from the side opposite to the punches, and rigidly connected with the press ram, and the pullers are placed on the movable plate.
