Abstract

The invention relates to the cold working of metals by pressure and can be used to fabricate parts made from tape material. The purpose of the invention is to expand technological capabilities and increase productivity. The goal is achieved by enabling the use of elastic forces arising in the compensation loop, which serves the billet to the press until the automatic stop is made in the form of a driving rotary body and mounted on the body of a rotary lever that interacts with the sensor. This embodiment of the stop ensures its automatic operation after the passage of the workpiece beneath it. f-ly. 7 il. $

The invention relates to the cold working of metals by pressure and can be used to manufacture parts from a tape material in an automatic mode.

The purpose of the invention is to expand technological capabilities and increase productivity.

FIG. 1 gfestavlena proposed line, general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 — view B in FIG. 3; in fig. 5 is a section of YYD in FIG. 3; in fig. 6 is a section d-d in FIG. five; in fig-. 7 - node I on phi1. one .

The line for izgotovleniya details of the ribbon material contains a coil 1, a correct feeding device 2, a loopback compensator 3, a press 4, an automatic stop 5, a mechanism 6 for moving workpieces, a processing machine 7. On a loopback compensator 3 there is a regulable attachment A hinge center 8, consisting of a roller 9 and sidewalls 10. A clamp 1 1 is mounted on the press jaw. The automatic stop is made in the form of a double arm on a lever, the hull shoulder of which is connected by a flexible element 12 to the electromat nit 13, through an axis

14, the pusher 15 with the shoulder b is connected to the body of the stop 5. The pusher

15 acts on the sensor 16 mounted on the case of the stop 5. The transporting belts 17 of the mechanism 6 for moving the pumps are located with a gap in which the pusher is placed

15 stops 5, pivotally mounted on an axis 18 mounted on the boom 19. The latter can move relative to the bar 20, and together with the bar 20 along the rod 21 mounted on the workpiece moving mechanism 6.

The mechanism 6 for moving the workpieces moves the blanks 22 cut from the tape 23 from the press 4 to the processing machine 7, and in the loop compat 3 the loops are supported by walls 24 that are adjustable.

Lini works as follows.

The correct-feeding device winds the tape 23 from the roll holder 1 and continuously feeds it through the loopback compensator 3 and the press 4 to the automat 182

It stops 5, while the tape 23 bends the top of the roller 9 of the hub 8 and rests against the shoulder L of the stop 5, pressing the pusher 13, which, turning on the axis 14, presses the sensor 16.

In this case, the core of the electromagnet 13 watts is wired and, through the cable 12, holds the abutment 5, thus preventing the tape 23 from moving further. By pressing the sensor 16, a signal is sent to the press 4, the punching and the piece 22 are stamped. At the same time, the press 11 presses down the clamp 11 in front of the chip and, preventing the loop from forming in the punching area, forms it in a loop compensator 3 looping 8 ,. The loop grows upward, supported by the walls 24. After the cutting off, the 22 slider of the press 4 moves upward, applying through a sensor (not shown) a signal to turn off the electromagnet 13 and the body of the stop 5 rotates on the axis 18 under the action of the cut workpiece 22, which moves under the shoulder L stops 5. At the same time, the shoulder slides along the surface of the workpiece 22 and the pusher 15 continues to press the sensor 16. After passing the start 22 under the shoulder b, the pusher 15 releases the sensor 16, which sends a signal to the electromagnet 13, and its core, W smiling, returns the automatic stop 5 to its original position. At this time, the press slider 4, continuing to move up, releases the clamp 11 and the tape 23 under the action of their elastic deformations of the loop

and its own weight is distributed,

The leveraging device feeds the tape until the front end of its shoulder B reaches abutment 5. Then the cycle is repeated.

In the proposed line there is no feeding device. In addition, the acceleration of the feed of the tape with the help of elastic forces leads to an increase in the productivity of the line.
