Description

The invention relates to wire drawing.

A drawing pack is known, including a rack of a fiber, a drawing cart with grip on the end of the workpiece and an additional fiber fitted with a reversing drive, a stationary clamping mechanism for the end of the workpiece located opposite to the rack of the mill end.

However, the productivity of the mill is reduced due to the need to set the workpiece in additional die after the first pass.

The proposed mill is characterized in that an additional fiber is installed before the gripper, and the gripper and the stationary clamping mechanism of the end of the workpiece are provided with means for removing them from the working position.

This makes it possible to increase the productivity of the mill by reducing the time required to refill the billet in the die before drawing.

Pa figs. 1 shows the proposed mill at the beginning of the forward and reverse travel of the trolley, a longitudinal section; “And FIG. 2 - the same in terms of.

The mill includes a fiber 1, a fiber 2 installed in a rack with a guide track 3, a drawing cart 4 with a gripping 5 of the front end of the workpiece mounted on it.

made with a lifting and lowering and additional die 6, equipped with a reversing drive 7, a stationary clamping mechanism 8 of the front end of the workpiece, provided with a means for removing it from the working position, for example, a drive of its vertical movement 9, located at the mill end opposite to the rack 2 -installation supports 10 rear end of the workpiece.

The camp works as follows. The billet 11 is shrouded at the end fed through the dies 1 and 6 into the grip 5. The drive 7 is turned on, the drawing cart 4 is moved, making the first draw passage. And through the draw line 1. As the cart 4 moves, the rear end of the workpiece rises; drop the ends of the products after.

trailing end.

After finishing the first draw passage, the carriage 4 stops under the stationary clamping mechanism 8 of the front end of the product, after which the grip 5 releases the product

11. The stationary clamping mechanism 8 of the front end of the product takes the place of the grip 5, the O1 start last, and captures the ends of the products P. The drive 7 is turned on, the drawing trolley 4 moves to the rack

2, made a second draw passage

through the die 6. As the carriage 4 moves, the supports 10 are lowered. At the post, the fiber 2 is lifted to the starting position using track 3. After the removed billet has been removed, the dicl is repeated.
