Description

The material supply board 5 Crawler 13 and 14, serving as a temporary stop, the Oda from the crawler springs, and the other is equipped with a displacement drive from the clip 15 fixed on the plate 2, which interacts with the walls 16 of the hole in the crawler 14. The slider 13 from the end facing the material 5, has a bevel of 17, and a protrusion 18 at the opposite end.

On the fixed plate 1 there is a fixed spring-loaded stop 19 located in the spring-loaded housing 20 and controlled by two pins 21 mounted on the plate 2, as well as the puller 22 and the slippers 23.

The stamp is provided with a pin 24 and a chute 25 for lifting the strip material 5 to the feed level, the tray 25 being located at a distance shorter than the length of the workpiece cut from the material 5 by the amount of tolerance for the length of the workpiece.

The operation of the stamp is carried out as follows.

In the initial position, both bunks of the guide sticks 10 under the action of their springs are in the most distant position from one another and do not hinder the movement of the material 5.

The spring-loaded slider 13 partially blocks the passage between the rulers, and, by acting on the protrusion 18 on the slider 14, it mixes the latter into a similar position,.

The material 5, moving between the rulers 10, with its front edge interacts with the bevel 17 of the slider 13, withdraws the last of the space between the rulers, and with further movement rests against the slider 14. As the plates 1 and 2 of the clone 11 move together, I affect the rulers 10, move The last one is one another, ensuring the installation of material 5 along the axis of the stamp II (Fig. 2) and clamping it to prevent distortion of the profile of the stamped workpiece. With the further approach of the plates, a piece is cut from the material of the measured billet with knives 3 and 4, and puncture 6 and 7 of the rectangular sections of the oval holes, which are then punched into the second die position. In addition, as the plates approach, the slider 14 by the wedge 15 is removed from the space between the lines 10.

When cutting the blank from material 5, the latter, resting on pin 24 and tray 25, falls below the feed level. When the movable plate is removed, 1 pin 24 and tray 25 move material 5 to the feed level. The wedge 11, moving with the plate 2, releases the liner 10, which under the action of its springs moves in opposite directions to its original position. The otlipateli 23 and the puller 22 remove the workpiece, respectively, from the punches 6 and 7. At this point, the crawler 13 and 14 are removed from

the spaces between the rulers 10, since the slider 14 abuts against the workpiece and does not have the ability to move under the action of the spring and the protrusion of the slider 13.

Upon reaching the movable plate 2, which is extremely distant from the non-attached plate 1 position, material 5 is moved by a step. Already processed in the stamp at the first transition, the workpiece is moved by the front conde of the supplied material 5 past the slider 14 to the fixed stop 19 to the piercing position of the previously threaded holes. At the next approaching plates pa first

the positions of the stamp occur the operations already described, and on the second, the punching of the holes by the punch 9 and the die 8. In addition, under the action of the pins 21, the housing 20 of the stop 19 is lowered, and the stop 19 itself is rotated and

turns out to be under the stamped part.

With the subsequent discrepancy of the plates, the next dilution of the guide lines 10 occurs, the removal of the finished part from the piercing punch 9 and the blank from the punches for

Note b and 7, the housing 20 with a fixed stop 19 rises, the edge of the stamped part is raised, which is then removed with further movement of material 5, the passage over the stop 19.

When the end of the material being stamped 5 approaches the spring-loaded tray 25, the waste material is rejected if it is less in length than the part to be stamped. If this waste is greater than the length of the part, then

it will be stamped in the next strip, and the remainder will also be discarded in tare. The slider 13 remains in its designated position, i.e., the slider 14 does not overlap the spaces between the linacs 10, and the punching

the next lane is produced by an abutment 19.

Claims (1)

Claims of the invention A multi-position die for processing a strip material comprising mounted on a fixed part of a ruler die, one of which is associated with a wedge fixed on the base of the stamp and informing it to move perpendicular to the movement of the material, a fixed stop and temporary unnor, moving perpendicular to the movement of the material and made in the form of a slider, interacting with the front end of the material and located from a fixed stop, at a distance equal to the length of the part to be stamped, characterized in that, in order to carry out automatic punching of a material with a wide margin of dimensions in width, the other ruler is movably mounted in the opposite direction relative to the first direction with the help of an additional wedge fixed on the movable part of the stamp, and the temporary stop is equipped with a second one, installed parallel to the first and springed in the direction of the material with a slider, butt cut to the material with a bevel and having a protrusion that interacts when moving with another slider, moved by of another additional wedge mounted on the moving part.5.
