Description

one

The invention relates to forging machinery, and more specifically to mechanical presses.

Mechanical presses are known, consisting of a frame, in the guides of which there is a slide connected to a connecting rod crank shaft, made in the form of a hinged link between the upper and lower link arms, controlled by a pneumatic cylinder.

The famous presses have a complicated control system and unreliable operation.

The invention is an increase in the working capacity of the press.

for this purpose, it is provided with a prismatic slide, which is hingedly connected to the crank shaft, mounted in a groove made on the upper lever of the connecting rod, and connected to an independent drive.

FIG. 1 shows the proposed mechanical press, section; in fig. 2 - position of the slider when the working stroke of the slide.

The first mechanical press consists of a bed 1 on which an electric motor 2 is mounted, connected by a flexible coupling with a flywheel located on a crank shaft (not shown in the drawings) placed in frame 1 whose crank carries

prismatic slider 3, moving reciprocatingly into the groove of the middle lever of the broken shagun as a result of alternating action of controlled telescopic cylinders o and U on it, which are connected to its lower lever /, interacting with the lower lever, connected with the lower lever /, which interacts with the bottom lever, connected to the lower lever /, which interacts with the lower lever / U moving in the guides of the sianins 1; and balanced in the form of pneumatic cylinders holding the slider in the upper position.

iViexaNews press is following orazome.

mounted on the bed 1, the electric motor 2 drives the flywheel through a giok connection, which couples the rotational crank shaft, the prismatic slider ci of the crank of the thio Topoio interacts through the broken crank on the slider next orazom; when the slider L is located in the extreme upper position under the action of the balancer Y and the slider t is located in the leftmost left of the groove of the upper lever 4 of the connecting rod, the eMoio control of the telescopic cylinder of the lever of the broken connecting rod rotates, and as a result there is no movement of the slider 8 from top position When the crank shaft is in the upper position of the crank shaft, as a result of turning off the cylinder 5 and turning on the telescopic cylinder 6, the slide 3 moves to the extreme right position of the groove of the upper arm 4 of the connecting rod, and consequently, when the crank shaft rotates from the rotational movement of the flywheel fixed on the shaft, crawl 3, the connecting rod p1dcha1 4 and its LOWER lever 7 move the slider 8 progressively to its lowest position and perform a working operation.

Simultaneously with the movement of the slide 8, the moving parts of the balancers 9 move.

The synchronization of the joint action of the slider 3 and the working shaft is carried out using

limit switches (not shown), giving the command telescopic cylinders 5 and 6 on the reciprocating movement of the slide 3 at the extreme upper position of the crank of the working shaft of a mechanical press.
