Abstract

The invention relates to mechanisms that serve to feed materials into the working area of a punch, mainly sequential action, and can be used to mechanize and automate cold forming works. The aim of the invention is to increase the reliability and accuracy of the material feed pitch. When the press crawl goes down, the carriage, and the carriage with the matrix rigidly attached to it, the stripper and the holder, seizes the workpiece with punches and moves it to the required feed step. During the return stroke of the press ram, the wedge mechanism of the stamp lifts the holder with the punches. The workpiece is released from the action of the punches, and the carriage returns to its original position. 1 h. n. f-ly, 3 ill. (L to with N3 00 00

Description

one

The invention relates to mechanisms that serve to feed materials into the working area of the punch, mainly of sequential action, and can be used to mechanize and automate cold forming works.

The purpose of the invention is to increase the accuracy of the feed step and the reliability of the capture of the supplied material.

FIG. 1 schematically shows a device, a longitudinal section; in fig. 2 is the same, in plan view, in FIG. 3 is a section A-A in FIG. 2

The device for feeding the tape material into the working area of the stamp consists of a blocking 1 and a feeding 2 carriages. The locking carriage is fixedly mounted on the bottom plate 3 of the stamp, it contains an adjusting bolt 4 and horizontally disposed spring-loaded knives 5. A wedge 6 attached to the top plate 7

stamp, give the feed carriage the opportunity of their transition into the upper vertical grooves, gate forward movement. The feed-in corresponds to the rearmost carriage position moves along two guide columns 8, the ends of which are rigidly embedded in the blocking carriage and the rack 9. Between the guide columns along the punch there is a spring 10, one end of which rests on the supply carriage and the other in the flange a guide rod 11 supported in a rack 9.

To move the carriage, the dowel 21 presses the plate 19 and moves the holder 14 with punches 15 and columns 16 down. The springs 18 are compressed, and the punches 15, moving down, pierce the holes in the tape, pass through it into the dies 12 and occupy the lowest position, corresponding to the gripping of the tape 23 by the punches 15 and fixing it relative to the removal of the slot of the feed carriage ik 13 and matrices 12, and therefore, and

The matrices 12 are mounted with a puller 13, along which a groove is made for passing the material and feeding it into the die. A floating carriage with respect to the feeding carriage, with which the puller and the dies are rigidly connected, is installed on top of the feed carriage at some height.

When the upper stamp plate moves upward, after the roller 22 leaves the upper vertical grooves of the wedges 6 and the slide 14 with the bores pressed into it into the inclined grooves, fed by the troughs 15 and columns 16, passing the crest 2 moves back - from the holes of the puller, dies and under him back to the frontmost carriage. Extreme upper position. At the same time, the punches 15 continue with the axial holders being limited to be firmly mounted in the belt, in their lower position

screw 17, screwed into the puller, and the spring for all the time of movement of the feeding carriage, us 18, put on the columns 16, ensured

for the direction of movement of the punches relative to the puller and dies. A support plate 19 is fixedly fixed to the holder from above. A wedge 20 is installed in the wedge, which serves to move the holder 45 with the punches mounted on it from the lowest lower position to the extreme upper position. A striker 21 attached to the upper die plate serves to move the holder down. The wedge 6 drives the feed carriage through the rollers 22 mounted on it.

In order to further describe the principle of operation of the device, it is necessary to select the initial (basic) position of the top plate of the stamp relative to the 55 horizontal planes, describe as always the bottom. As such a position is a rectangle pattern.

side of the stamp at a given feed pitch. At this time, the knives of the blocking carriage are pressed and slid along the side edges of the tape.

Upon further raising of the upper plate of the stamp, after the pins 20 touch the lower plane of the holder 14, the punches 15 begin to rise and with the opened stamp take up their upper position.

Further, the cycle of operation of the device is repeated.

Thus, in one double stroke of the press ram (in one cycle), piercing punches, moving in vertical and

The effect of using the device is to increase the reliability and it is clear that the stamp is opened, the press slider is in the upper position.

The device for feeding the tape material into the working area of the stamp works as follows.

When the top plate 7 of the stamp moves downward, after the rollers 22 begin to move along the inclined grooves of the wedges 6, the carriage 2 feeds along the two guide columns 8 from the front to the rearmost position. At the same time, the spring-loaded holder 14 with punches under the action of the springs 18 continues to be in the extreme upper position for the entire time of movement of the feed carriage from the stem.

When the feed carriage is moved from the spreader (back), the workpiece 23 remains stationary, as it is wedged by the knives 5 of the locking carriage 1.

Upon further movement of the upper plate shtamp down, after the release of the rollers 22 from the inclined grooves of the wedges 6 and

To move the carriage, the dowel 21 presses the plate 19 and moves the holder 14 with punches 15 and columns 16 down. The springs 18 are compressed, and the punches 15, moving down, pierce the holes in the tape, pass through it into the dies 12 and occupy the lowest position corresponding to the grip of the tape 23 by the punches 15 and fixing it relative to the removable carriage with which the puller and matrices are tightly coupled.

When the movement of the upper plate of the stamp up, after the release of the roller 22 from the upper vertical grooves of the wedges 6 and hit

horizontal planes, describe the trajectory of the rectangle.

side of the stamp at a given feed pitch. At this time, the knives of the blocking carriage are pressed and slid along the side edges of the tape.

Upon further raising of the upper plate of the stamp, after the pins 20 touch the lower plane of the holder 14, the punches 15 begin to rise and with the opened stamp take up their upper position.

Further, the cycle of operation of the device is repeated.

Thus, in one double stroke of the press ram (in one cycle), piercing punches, moving in vertical and

 horizontal planes, describe the trajectory of the rectangle.

The effect of using the device is to increase the reliability and accuracy of the material feed pitch in the working area of the stamp, advantageously consistently.
