(54) DEVICE FOR THE MERNOR1 CUTTING OF CONTINUALLY MOVING PROFILE RIWERS

one

The invention relates to the processing of metals by pressure, in particular, to devices for metal cutting and can be used in industry for cutting continuously moving rolled steel.

A device for measuring cutting of continuously moving sectional rolled products is known, comprising a base, a cutting head with movable and fixed blades, mounted for reciprocating movement in the direction of the rental axis, and a stop 1 located along the feed axis.

However, in this device, setting up for a cut of various lengths is complicated; in addition, the device does not provide high quality cut.

The purpose of the invention is to simplify the setting for cutting steel of various lengths and increasing the quality of the cut.

This goal is achieved by the fact that in a device for measuring cutting a continuously moving sectional rolling containing a base, a cutting head with movable and stationary knives, installed with the possibility of reciprocating alternation in the direction of the axis of supplying the rolled product, as well as a stop located along the axis of feeding , the base is provided with beams for guiding the cutting head and a copying unit, and the cutting head is equipped with a rolling clamp mechanism, pivotally mounted in its upper part with a lever ikami arranged to cooperate with a follower unit of a base, and a spring-loaded polzushkoy placed, with

10 interacting with said lever, wherein the movable knife is mounted on a spring-loaded slide, and the cutting head is spring-loaded with respect to shtang.

FIG. 1 shows the device, a general view; in fig. 2 - the same plan view;

15 in FIG. 3 - kinematic scheme.

The device comprises a cutting head 1 and a frame 2. The cutting head 1 includes a clamping mechanism 3 of continuously moving rolled metal, consisting of a fixed clamp 4 rigidly mounted on the rack 5 of the housing 6 and a movable clamp 7, which performs a reciprocating movement, interacting

with a rod 8 pneumatic cylinder 9, rigidly mounted on the plate 10 of the housing 6.

From turning the clamp 7 is fixed by a screw 11. On the other side of the stand 5 of the housing 6 there is a cutting mechanism 12, a fixed knife 13 fixed rigidly directly to the stand 5, a movable knife 14 with a slider 15, in the spring of which 16. The knife 14 is inserted using the slider 15, reciprocates along the directions, the surfaces of the holder 17 fixed to the stand 5, interacting with the lever 18 pivotally connected to the stand 5. At the second end of the lever 18 two rollers 19 are fixed, sliding along the lower plane copier knot 20 frame 2 installed at an angle to the horizontal plane. In the rack 21 installed on the frame 2, a measuring line 22 is fixed, with divisions printed on it, to set the length of the trimmed rolled product along which the sleeve 23 is mixed with the stop 24 hinged on it.

The cutting head 1 makes a reciprocating movement along two rods 25, on which springs 26 are dressed, which serve to return the cutting head 1 to its original position. The rods 25 are rigidly fixed in the rack 21 of the bed 2. To see the impact of the cutting head 1, when it returns to its original position, there are shock absorbers (not shown).

The device works as follows.

On gauge 22, an emphasis 24 is exposed on the length of the profile being cut. From the feeder, the rolled section passes through the cutting head 1 up to the stop 24. When the profile touches the stop 24, the profile is clamped. The cutting head 1 moves along the rods 25, compressing the spring 26 synchronously with the moving profile. The rollers 19 of the lever 18 cat TC on the lower inclined plane of the copier

nineteen

node 20. The lever 18 presses on the sliders 15, the profile is cut. The cut profile falls. The rollers 19, income until the end of the copier assembly 20, are pushed by the spring 16, the knife 14 with the mandrel 12 returns to its original position. The profile moves further, and the cutting head 1 returns to its original position under the action of the springs 26, dragging the lever 18, with the rollers 19, which roll along the upper plane of the copier assembly 20. The cutting process is repeated again.

The proposed device for dimensional cutting of rolled products has a simple setting for cutting of rolled products of various lengths and provides high quality cutting.
