Description

The invention relates to the processing of metals by pressure and can be used to automate the punching of thin-walled deep-drawing parts in any punching industry.

The purpose of the invention is to increase the productivity of the stamp by combining the punching operation and turning the turret disk.

FIG. I shows a device, a plan view; in fig. 2 - section A-A on fshg. one; in fig. 3 shows a section BB in FIG. 2 (the moment of the upper (initial) position of the movable plate); in fig. 4 shows a section BB in FIG. 2 (moment of the lower position of the movable plate).

Shtmg 1 contains a movable plate 6 connected to the Vulvo .vi 1, the stopper 7 of which is installed, the stripper 8 having CToiiKa 9, 1-1 and with the movement of the mouth 1- |; 10, having guides for ;; ng (gopop11 5, p spring 11, pressing up i, j5i; i; iMT if: i; stand 9 collar, fixed iioinrv 12, lia spor 13, the sleeve 13 is fitted with a die 14 in it.

T;) the aport revolving means 2 comprises a housing 15, on which a fixed plate 16 is mounted. On the settling section is installed a tray 17, (|) a hinge 18, a limit switch 19 and a clamp 20. In the housing 15 n clamp 20 is movably mounted revolving The cpc 2, in which the slots 22 are made. The holder 20 prevents the 1P .saro OROK 5 from falling out of the slots 22.

From athe; 1 содержит 3 contains a housing 23 with right-handed units, on which a pi-lock 24 is mounted and a stationary electromagnet 25 is fixed, Hiapnnpito is connected with the lever 24.

The original device of the device is shown in FIG. 1 and 3, in which the slide of the press n connects with it a movable plate 6 with a poopson 7, a puller 8 and a stand 9 are in the upper position, the plate 10 is pressed by an extremely compressed spring 11 to the projections (not shown) on the plate 16 and the housing 23 and is in the extreme upper nolozhenpi, the revolving disk 21 is fixed, the blanks 5 are in the guide plates 10, in the nest 22 and in the guides to): 1us 23, the flag 18 under the action of salvage 5 turned and entered into the pharynx of the end 19, which vklyuchil press clutch p electromagnet 25, lever 24

removed the workpiece, on the code in the guide bodies 23 from the workpiece on the plate 10. There is a gap between the upper end of the workpiece 5 and the puller 8.

The device works in the following way. Simultaneously with the movement of the press ram, the movable plate 6, the punch 7, the puller 8, the pillar 9 (the spring 11 is pulled down) and the revolving disk 21 are lowered down.

the movement of the press ram by the amount of the gap between the upper end of the workpiece 5 and the puller 8 rotates the revolving disk 21 by the amount at which the workpiece 5 located in the socket 22 is removed from the workpiece 5 located on the plate 10 and its flange does not may place the lowering of the workpiece located on the plate 10. 13 this .MOMeirr stand 9 own meters of burtore is pressed into the plate 10, for which cost is 5, the last with the plate

0 10 1 Begins to descend, meets on its way the cone of the yoke 13, which ensures an oriented installation on the matrix 14 of the throat of the workpiece 5.

During the entire run of the press ram

5, the revolving disk 21 rotates in the bearings mounted in the housing of the turret means 2, while the workpiece 5 moves along the fixed plate 16, and the yoke 20 prevents the workpiece 5 from falling out of the slots 22. At the end of the stroke of the field, the charger 21 on the revolving disk 21 stops, billet 5 from slot 22 enters tray 17 and is removed, at the same time punching the hole with the pugnone 7, the spring 11 is decompressed into the hole of the plate 12, 1. The mechanism occupies the lowermost half shown in FIG. 4, after which |; the slide of the belt moves upward with the plate 6, the punch 7 mounted on it, the puller 8 and the pillar 9. The turret disk is stationary during this period. In the process of moving the plate 6, the puller 8 removes the workpiece 5 from the ia 7 punch, and then the plate 10 removes the workpiece 5 from the sleeve 13 and the die 14 and, as soon as the top plane of the plate 10 is in the same plane as the top plane of the fixed plate 16, the plate 10 will stop

5 into the anvil on the platter 16 and the housing 23 and stops, the electromagnet 25 is provided and the lever 24 is rotated to pass the blanks 5 through the guide bodies 23 of the shutter. 3. After stopping the plate 10, it begins to compress n) dinner 11, since the movement of plate 6 continues and, when there is a gap between the upper end of the workpiece 5 and the end of the stripper 8, working continuously the V-belt conveyor 4 by friction will move it one by one billets 5, through cutter 3, billet 5, located on 1lit 10, into slot 22 of the revolving disk 21, onto plate 16, where the blank presses flag 18, which closes limit switch 19. The latter turns on the press clutch and electromagnet 25, and the cycle repeats, since crawling un and all mechanisms came to the starting position.

Download blanks 5 on the conveyor 4 is done manually, if the device operates autonomously, and from the previous press - in an automatic line.

Installing the V-belt conveyor, which feeds the friction flange one by one into the die, in combination with a cutter, allows the shutter to move the blanks away from the blank that is below the die to the width of the flange and, when lowering the mechanism for moving the blanks in the direction perpendicular to plane of the turret disc, workpiece,

J 26

located in the stamp will not touch the crawled flange of the subsequent billet.

Installing a revolving tool after the stamp so that the revolving disk does not pass over the die when turning, allows the disc to begin to rotate simultaneously with the press ram move and to produce it throughout the entire press slide stroke and to perform a technological operation.

Ensuring the revolving disk rotation during the entire stroke of the press ram allows processing of workpieces of increased diameter at acceptable speeds of disk rotation, and using the entire stroke for performing a technological operation - the height of the workpieces, which expands the range of workpieces on a single press.
