Description

The invention relates to pneumatic rentals with contact electric heaters and is used in the metal industry for veneering furniture furniture edges.

Known pneumowire, including the frame, the clamping mechanism, the mechanism of fixing clamps and stops P.

Also known pneumowire, including support frame, traverse, pneumatic cylinders and beam C2.

A disadvantage of the known pneumoim is a considerable expenditure of working time on their remaking.

The purpose of the invention is to reduce the time of the live storage.

This goal is achieved by the fact that the beam is fixed to the support frame by means of eccentric clamps with clamps, and the pneumowire is equipped with rolling bearings and a counterweight.

Fig, 1 shows a pneumatic face, front view; in fig. 2 is the same side view in FIG. 3 is a section A-A in FIG. one; in fig. 4 - view B in figure 1.

The pneumatic liner contains a support frame 1, a traverse 2, pneumatic cylinders 3, a beam 4 moving relative to

channels 5, which are integral parts of the support frame 1.

Two housings 7 are fastened to the beam 4 by means of bolts b, including an eccentric roller 8, pressing the arm 9 and the stop 10 bale 4 to the channel 5 by means of a bar.

The fixing of the beam 4 is carried out using a spring-loaded lock

10 11. Raising and lowering the retainer 11 is accomplished by sliding the pin 12 along the end of the cam 13 rigidly connected to the full beam 4.

To prevent the beam from falling spontaneously 15 and reducing physical efforts as it moves, a counterweight 14 is provided, connected to beam 4 by a flexible cable 15 slung over block 16.

20

In order to facilitate movement of the beam 4 relative to the channels 5, the pneumatic lift is equipped with rolling bearings 17.

25

Pnevmowayma works in the following manner.

The end of the retainer 11 enters the apertures of the cam 13, the flanges of the horizontal beam 4 and the inclined post, 30 made of a channel bar. Eccentric

8 clamps the stop 10 and the beam 4 relative to the channel 5,

To reconfigure the pneumatic lines, it is necessary to loosen the clamp of the beam 4 with the handle, 9 eccentric 8. At this, the stop 10 moves away from the channel 5 and a gap between the stop 10 and the channel 5 is formed. . In this case, the pin 12 (pressed in the latch 11) slides up the inclined plane of the cam 13 and in the upper position

is fixed in the radial recess, with the force compressing the spring of the retainer 11 increases. After

This beam 4 can be moved up or down with the help of pliers 17 relative to the channels 5.

To bring the pneumatic belts into working position, it is necessary first to fix the beam 4 relative to channel 5. To do this, slightly turn the latch handle 11 in the opposite direction,

and due to the force of the spring, which will cause the pin 12 to slide along the inclined plane of the cam 13, the latch 11 will return to its original position. Further, the handle 9 of the eccentric 8 clamp the stop 10, which respectively clamp the beam 4 relative to the channel 5.
