Abstract

The invention relates to the cold processing of metals by pressure and can be used to feed a sheet into the working area of a press during multi-sided stamping of parts from a sheet. The goal is to increase the reliability of work. The sheet for carrying out multi-sided stamping of the parts of the mix, is in two mutually perpendicular directions in the horizontal plane, i.e., along the front of the press and in the direction perpendicular to the front of the press. Perpendicular to the front of the press, the sheet is moved by the carriage up to the stop mounted in the working area. The carriage moves from a gravity drive, made in the form of a load, connected with the carriage through a chain hoist mechanism. The carriage is mounted on a table and moves along rails mounted on a base parallel to the front of the press. In the stop mounted material availability sensor. The step motion of the table is carried out by a drive carriage. The feed pitch is determined by an adjustable stop. On the base, final rotators are installed that interact with the thrust and are connected with the drive carriage drive. A brake carriage is also mounted on the base, locking the table against movement when the drive carriage returns to its original position. The table is returned to its original position by a load connected to the table through a chain hoist mechanism. The carriage is equipped with a mechanism for its fixation relative to the table, made in the form of a driving brake sponge. 1 il. S S (L

The invention relates to the field of cold forming of metals by pressure and can be used for nodachi sheet material in the working area of the press for multiple stamping of sheet parts.

The purpose of the invention is to increase the reliability of work.

The drawing shows a device for feeding sheet material into the working area of the press.

The device contains a table 1, installed in the directions of the lower 2, mounted on the base 3, guides 4, fixed on the table 1 perpendicular to the direction of 2, feed, carriage 5, carrying

The device works as follows.

The sheet 7 of the blank for stamping is fed to the table 1 and secured by the clips 6, is brought to the stop 15 of the punch 13 under the punch 10. Press the button 5 "Start with the switch 31 and the slider 9 with the punch 10 and the bran knife 1 goes down until the specified part is cut. At the same time, a signal is sent to the switch 14, at the command of which, when moving, the research institute of the slide 9 with the punch 10 and the cutter knife 11 unlocks the clips 34 and 33 of the brake carriage 32 and releases the clutches 26. electro-hydraulic drive 27,

Achvatsy 6 for sheet 7 and set-move table 1 with sheet 7 until it stops 29. It goes in direction;) 4. Base 3 Turns on switch 31, on command

The press 8 has a slider 9, on which a punch 10 punch and a bran knife 11 are attached.

On the bottom plate 12 of the press 8, a stamp 13 and a limit switch 14 are installed.

On the stamp 13, a working stop 15 is installed behind it, made in the form of a guide bar located parallel to the front of the press 8, i.e. parallel to the guide 2.

wherein the slider 9 goes down, the clips 34 of the brake carriage 32 are clamped, the clips 23 and 25 of the carriage 22 are unclenched and under the action of the spring 28 the carriage 22 is returned to its original position. The punch 10 cuts a predetermined part (not shown), and the cutter 11 separates the waste sheet 1 (not shown) from the sheet 1, and the cycle repeats until the cutting of the parts from the predetermined width is completed. the entire length of the sheet. Then, the switch 37 is turned on, at the command of which the clips 33 and 34, 23 and 25 are opened, unlocking the table 1, which along the length of the stop 15 mounted sensors 16 (17 of the sheet 7 (material) are present. The carriage 5 moves along the guides 4 in the direction to press drive

wherein the slider 9 goes down, the clips 34 of the brake carriage 32 are clamped, the clips 23 and 25 of the carriage 22 are unclenched and under the action of the spring 28 the carriage 22 is returned to its original position. The punch 10 cuts a predetermined part (not shown), and the cutter 11 separates the waste sheet 1 (not shown) from the sheet 1, and the cycle repeats until the cutting of the parts from the predetermined width is completed. the entire length of the sheet. Then, the switch 37 is turned on, at the command of which the clips 33 and 34, 23 and 25 are opened, unlocking the table 1, which, along the longitudinal guides 2, returns to its initial position through the action of group shifting, made in the form of a load 18, 30 for 38. the mechanism of the polyspast 19, I will act on the switch 36,

with | carriage. The mechanism of the polyspast 19 was mounted on the table 1.

I A carriage fixing mechanism is mounted on the carriage relative to table 1, with the action of load 18 being fed up to the stop 15.
