Description

The invention relates to the building materials industry and can be used in the manufacture of bricks and other wall ceramic materials.

The aim of the invention is to improve the geometry of the cut.

FIG. 1 shows the proposed device for cutting a measured beam, side view; figure 2 - section aa in figure 1; on fig.Z - view B in figure 2.

The device contains a frame 1 and a cutting body, made in the form of the body 2, installed KQRjif. ... on the rods 3 of the mechanism 4 of the measurement; and the spatial position of the cutting body, copiers 5. mounted on the rods 6, directed 7 and 7 telescopic arches 8 with rollers 9, along the axis of which the cutting string 10 is tensioned.

Mechanism 4 is a screw connection that provides adjustment of the position of the cutting member in two planes. Guides 11 are mounted on the body 2 of the cutting body, on which a carriage 12 with a hinged latch 13 of the beam, a breaker 14 and an emphasis 15 of the latch 13 are mounted.

The device also contains a transporting body 16 with stops 17, excluding the creep of the beam, and a power take-off drum 8 mounted on the frame 1 and connected by a synchronization mechanism in the form of a gear 19 with telescopic beams 8.

The power take-off drum 18 contains annular sectors 20 that are connected to its body 22 by springs 21, and interact with cone-shaped surfaces of the pusher 24 installed in the threaded sleeve 25 of the body 22 through the strips 23. The power take-off drum 18 by a flexible organ 26, for example a cable , connected to the carriage 12 through sector 27 with the dog 28 and the ratchet wheel 29.

The carriage 12 is connected to the cutting body by a spring 30, and the sector 27 is seated on the shaft of the power take-off freely.

The cut-off measuring bar is diverted by an overrun conveyor 31.

The device works as follows.

The beam leaving the press sets in motion the belt conveyor 16, which through the power takeoff drum 18 and gears 19 synchronously lies the telescopic beams 8. The lights 8 with their rollers 9 move along the copiers 5, changing their radius, which sets the cutting string 10 on the section of the cut the necessary law of motion, which

provides the correct geometry of the cut bar, and the guides 7 exclude the interaction between the cutting string 10 and the cut and incoming bars.

In this case, the stops 17 fixed on the belt transporting body 16 exclude slipping of the bar relative to the tape at idle speed of the cutting string 10, and in the section where slippage is most likely, the beam additionally interacts with the folding latch 13 of the carriage 12 which through the cable 26 and impaled The sector 27 with the pawl 28 and the ratchet wheel 29 strictly defines the tracking system on the axis of the power takeoff drum. Sector 27 is structurally configured in steps with a range of radii of the guide grooves of the cable 26 corresponding to the range of adjustment of the diameter of the power take-off drum.

The moving bar moves the carriage 12 along the guides 11 until the end of the cut, after which the breaker 14 deflects the stop 15 of the lock 13 m. The cut bar moves the folding lock 13 around its axis of rotation upward and is discharged by the discharge conveyor 31.

At the same time, the carriage 12 and the sector 27 are returned to their original position by the action of the springs 30 and the counterweight (not shown).

Next, the cutting cycle is repeated.

The adjustment of the device for cutting timber of any length and height is carried out as follows.

While ensuring the specified length of the measured beam, the diameter of the power take-off drum 8 is adjusted with the help of the pusher 24 and the flexible member 26 is installed along the radius of the guide groove of sector 27 corresponding to the power take-off drum radius.

While ensuring the correct cut geometry, adjust the height h from the horizontal axis of the cutting body to the belt transporting mechanism 4 of the spatial position of the cutting body to ensure its movement in two planes: in vertical to ensure the calculated position of the axis of rotation of the cutting body and in the horizontal to ensure engagement in gear transmission; the radius R of the copier 5 is adjusted by radial movement of the bar 6 and the angular position of the copier .5, i.e. angle cf, by turning the rod 6.

The conversion is carried out using tabular data calculated for the entire range of required lengths and heights of the measuring bar.
