Description

A pressure automatic machine with pressure rollers on spring levers, each approaching an axially adjustable cone, is proposed in which the axis of the spindle of the tailstock movable along the axis is connected with a hollow core inside it and an additional spring with an outer bar, which is attached to on the spindle with a cone, and the strip with a clip freely attached to the spindle with pressure rollers and with a clip with a cam for activating the spring pin. The working and idling speed is communicated to the tailstock mechanism via eccentrics and lever gear associated with the outer rail.

The finished product is trapped by a conical undercut and spring tabs at the spindle end. The working stroke in the mechanism of the tailstock can be terminated by a latch on one of the levers that transmit pressure to it.

In the drawing .fig. 1 shows schematically a general view of the machine with a partial section of the bed; FIG. 2 is a view of FIG. 1 on the left, a section along the line ABCD (some of the details are taken away); FIG. 3 - section verti310

the axial plane of the spindles with the parts of the machine sitting on it (the scale is increased); FIG. 4 part view of FIG. 3 below, with a horizontal plane cut.

The machine consists of the headstock T (Fig. 1) and the tailstock 2 carrying the hollow spindle 3. The movement of the headstock spindle is communicated from the engine through the pulleys 4, and the axial movement of the spindle 5 is achieved through the pulleys 5,6, worm gear 7, 8 v (further through the eccentrics 9 and P, the system of levers 10 11,12,13 and the yoke 14 supporting the front of the tapered cam 15; When the yoke 14 moves along the spindle to the left - the cam 15 lifts the end of the lever 7b of the rolling pin 17 that is pivotally hinged with the spindle on the spindle 17 (Fig. 3), inside which there is a finger 18, pressed down by a spring 19, after The end of the finger 18, which is located in the recess of the hollow core 20 (Fig. 3) inside the spindle, is raised. Core 2 (7 is equipped with a spring 21 on the left end and, moreover, a screw 22 passing through lobes in the spindle, it is connected, with a cone 23, loosely worn

"A spindle 3. At the left end, spindle 3 is loosely fitted with a yoke 24 connected by rods with a bar 25, which, in turn, is connected by a spring 25 to a core 20. When the end of the rod 78 is lifted out of the recess in the core, the spring 27, due to rigid connection with the cone 25, through the screw 22 of the core, squeezes the latter against the wall of the tailstock, and the spindle together with the holder 24 and the arms seated on it with the rollers 26, 27 moves to the left.

The roller 27, falling on the constricted part of the cone 2, under the action of the spring 28, lowers, and the roller 26 finds on the processed capsule: The capsule itself is put on the glass with the 2P ring, the right end of which is shaped in the shape of a capsule. The glass is placed on the end of the spindle of the headstock, and between its flange and the flange on the spindle is placed a spacing spring 30. The end of the spindle against the capsule is cut to the same slope with a cone 25. The capsule is crimped with a roller 26, during the ejection of the head 27 with a cone 25, when moving the yoke 24 and the spindle to the headstock. At the end of the spindle 5, an elastic buffer J / with a pin ball is fitted to eliminate impacts and friction between the ends of the spindles. In addition, at the end of the spindle 3, the spring tabs 32 are fastened with their ends, with which the capsules are prepared and gripped. is pressed into the conical recess 55 on the spindle DEL 5 to eliminate damage from impacts, due to the rapid rotation of the spindle when the finished capsule is dropped by the spring 30 with the ring 29. To quickly stop the working stroke of the spindle, in the event of damage or incorrect operation, a latch 33 is set on the lever 12 with a handle, which when turning the lever / 2

will be able to rotate on the hinge at the lower end of the lever / 5 without moving its upper end, and hence the holder M, and the spindle 5.S
