Description

I

The invention relates to the machine-building industry and can be used as a permanent technological attachment to cold-landing machines for editing and removing the deformed part of the riot material.

Known-setting devices are known, containing correct and feed rollers, one of which is made lowered from the power pneumatic cylinder, drives the feed roller, the support of the supporting roller, for length. suspending the riot material, made in the form of a casing, in which the drive roller drive, which is a gearmotor, as well as knives for cutting the deformed part of the riot material, is mixed.

The existing known correcting devices provide the processing of the riot mwgteriala only with the right or left coiling, as a result of which there is a need to reposition the l-slicing mechanism.

I

The aim of the invention is the expansion of technological capabilities. This is achieved by the fact that the cutting mechanism is made in the form of a pair of wedge-shaped knives located in the housing along the axis of the feed rollers.

FIG. I schematically shows the device, front view; on fig. 2 - as well. view along arrow A in FIG. 1, in FIG. 3 - the same section; in fig. 4 10 isometric projection of the straightening mechanism.

Claims (1)

The driver assigning a cooling machine to the cold-cooling machine includes a bus 1, on the bad wall of which the correct rollers 2,3 are located, as well as the feed roller 4 and the upper roller 5 moving in the radial direction. In the area of the feed rollers 4.5 and 20 there is a cutting mechanism, made in the form of a hygrostrum 6 and a pair of wedge-shaped knives 7 8 placed in the housing 9 along the axis of the feeding rollers 4 and 5. 74 Knife knife 7 can be mixed and fixed on the rod of hydrocylinder 6, and the wedge-shaped knife 8 is fixed and fixed on the body 9 of the segment mechanism. In the opening of the housing 9 of the mechanism of cutting under the fixed knife 8 mounted on bearings 10, the shaft 11 of the drive for raising the lower feed roller 4. The mechanism for lowering and lifting the upper feeding roller 5 is made in the form of a clamping beam 12, which bends the cutting mechanism and moves along the rolling pin 13 and 14 by means of hydraulic cylinders 15 and 16, fixed above the mechanism of segments on both sides of it. On one axis with the lower feed roller 4, the supporting roller 17 is housed to hang the riot material 18 being processed. The supporting roller 17 is mounted at one end on the extension of the shaft 11, and the second end on the support 19 made in the form of a casing 20 in which the gear motor 21 for driving the rotation of the feed bottom roller 4, placed inside the processed riot material 18. The correct setting device is equipped with a lift limiter 22 installed between the cut off body 9 and the clamp-shaped grass soi 12 and provides a limited movement of the upper first roller 5 with passage 18 Buntova material without clamping. For processing, the riot material 18 is hung on the support roller 17, the end of the riot material 18 is inserted beyond the cut-off 23. The deformed end of the riot material 18 is placed on the fixed wedge-shaped knife 8 | pneumatic valve handle 2 is moved to the position of the segment ill. The sliding wedge-shaped knife 7 is lowered and produces a segment of the deformed end of the riot material 18. The knob of the pneumatic distributor 24 is transferred to the L position, lifting 1; and the wedge-shaped knife 7 is returned to its original position. The machined one (the end of the riot material 18 is installed in the streams of rollers 2,3,4, while the feed roller 5 is in the upper position. The knob of the pneumatic distributor 2 is set to the edit position I, the upper walking roller 5 is lowered onto the riot material 18 and produces pressure on it with a force of 3.3 tons. By turning the lever of the switch 25, the motor-irradiator 21 is turned on. The shaft 11 rotates the lower feed roller 4 and straightens the riot material and then feeds it into the working zone of the cold-landing machine 6. Gearmotor 21 is switched on and off as needed by one of the foot pedals 27, 28. At the initial moment of operation of the cold-rising machine). 26, the pneumatic distributor handle 24 is placed in the I-up position, the lift limiter 22 is inserted between the shearing mechanism body 9 and the clamp-type crosshead 12, and the lifting roller 5 is set to the limited stroke mode by means of the lift limiter 22. The riot material 18 without clamping the strands of the correct and feeding rollers 2-5 freely and reliably passes into the working zone of the cold-landing machine 26. When processing the riot material 18 with opposite winding of turns, the correct-setting device with respect to the cold-landing machine 26 turns on 180, the cutter 23 is mounted on the opposite side of the casing 2O and all operations are performed in the order described. The use of the correcting device as a constant technological attachment to the cold-landing machine provides conditions for the processing of the riot material both from the right and left winding without changing over the sectioning mechanism, and also allows removing the deformed end of the riot material no burrs into the receiving device of the cold-landing machine without any additional processing. The proposed design of the correct-setting device is more compact due to the arrangement of the mechanism of sections in the area of the correct rollers, as a result of which much less space is required for its operation. Claim setting device containing a supporting roller mounted in a housing, upper and lower feed rollers with a drive for moving the upper roller and a cut-off mechanism characterized in that 5740362 expansion of technological capabilities, the mechanism of the segments is made in the form of a pair of wedge-shaped knives placed in the housing along the axis of the best rollers.
