Description

one

A vertical type setting is known for a hot strip of a mesh strip comprising — a chamber with a protective gaseous medium, movable and fixed clamps for gripping a mesh nose, and a weight for stretching a strip.

For the purpose of automating auxiliary operations, the fixed axis of the drum is equipped with a cam-cam interacting with fixed clamps installed at each position, and the weight for stretching the strip is connected to the | S sporotom, imenyu1, I1M slot for driving the heads of the stems with control and idling: .

FIG. 1 shows a diagram of the proposed device; n.a fig. 2 - the mechanism for opening the fixed mesh nOviocbi.

The proposed device contains a chamber 1, which is continuously filled with protective gas (tension, hydrogen), a multiposition drum 2, fixed, and a fixed axis 3. Barabai 2 has slots along its generators, each of which has a mobile 4 and a foam 5 Clamps for mesh strip 6.

At the ends of the drum there are contacts 7 and 8 d.1 for supplying voltage to zazlma-m 4 and 5. The stationary axis 3 is equipped with a cam 9 interacting through the pusher 10 with the installed: And at each position of the drum with non-idle moving clips 5. Transferring baraoan from position to the position is carried out by camK1M 1.1 through a rack gear 12. Cam Id is mounted on a camshaft 13, which is driven from an electric motor via a belt drive and a reduction gear. A camshaft 14 for lifting and lowering the load 15 is fixed on the camshaft. The load is through the cable 16 and the rod 17 is connected to the latch 18, the notch groove 19 for driving the heads of the rods 20 to control the movable clamps.

The netting strip 6, which is to be stretched, is placed at the position of the drum 2 so that its ends are placed in the p-jaws of the clamps 4 and 5. When the drum is rotated, the stationary clamp 5 automatically grabs the ends of the strip when the interaction of the cam 9 with the pusher 10, the strip is introduced into the chamber, where atmospheric air is displaced by a protective gaseous medium, but replaced with new pressure.

With the approach of the grid strip to extractor hood, the fist 14 lifts the load 15 and the spring p-18 moves to the front position so that at the moment of the reel stopping the head of the control rod 20 controls the movable clamp enters the groove 19 of the retainer 18. In Time of the drum, the cam 14 frees the load 15 and it retracts the lock / 5, and along with it, the movable clamp 4, the lips of which capture the end of the net strip. Strip

when voltage is applied through pins 7 and 8, the loudness of the heater heats up and the load is expanded. When a new rotary drum 2 company is loaded 15, the load is 15 TURNED, releasing the latch 18, the head of the rod 20 comes out of the naza of the latch. The cooling of the grid strip occurs, it leaves the chamber and enters the unloading and loading position. When this happens, the fixed clamp opens. The worker opens the jaws of the sliding jaw 4, takes out the treatment of the mesh strip and inserts a new one. The cycle of operation of the device is repeated.

Subject and use of the device for stretching the mesh strip,

containing a chamber with a protective gaseous medium, a multi-position drum on a stationary axis, on each leg of which there are mobile and stationary clamps, and a weight for stretching the strip, characterized in that, for the purpose of automating auxiliary operations, the fixed axis is provided with a cam, interacting with fixed points, the end of the drum is equipped with at least a Meipe with one rod with a head cooperating with movable clamps, and the device is equipped with a fixture connected to the load with slots for inserting the head of the stick.
