SU45585A1 - Tool for automatically feeding the rolled material into rolls - Google Patents

Description

The proposed device serves to automatically feed rolled products (for example, fork blanks) to the bobbins of the sector mill.

In FIG. 1 is a front view of the installation; FIG. 2 is a top view and FIG. 3 side view.

The device is made in the form of two suportops A and B installed on the bed, having reciprocal movement. The upper caliper I has a clamp G for holding the rolled billet and carries two combs D and E with dogs Z and 3 pressed to them. Along the bed on two subjoint supports, U set the carrier //. The lower working sector 20 is provided with a finger Af acting on the carrier H and causing it to reciprocate.

At the end of the carrier I have a tightly articulated arm O with a spring F pushing down n & the free half of the lever O. The free part of the lever O enters the groove of the rod end / 7. The lever O serves as a link carrier with a rod / 7. The carrier H and the lever O move during the whole time of the mill, and the rod / 7 only when the lever O is in the groove on its end.

The rod / 7 passes through the lining of C connected to the port B. By both

the sides of the backing C, resting against it, with one end put two springs X on the rod, and from the other end each spring rests on a retaining ring W fixed on the rod / 7 so that the rod / 7 as it moves through the rings W and the springs And the caliper is driven by B. The action of the adaptation is as follows. A heated billet 2J is put into the clamp D, the upper slide B is retracted by the handle C to the rear extreme position, the spring P is compressed and the support B is held in this position by the dog abutting the comb M. The switch 7 is at the time left in the left in the extreme position, the zayd between the support-guide W and the end of the lever O he lifts the end of the lever O upwards and leads him out of the groove in the rod; at this time, the rod / 7 and the support B remain fixed.

When starting the suporta B, the switch T by the handle U is moved to the extreme right position, after which the switch, the slide slides on the support — the slide U, drops down, and with it the end of the lever O is lowered. Lever O, slide on the rod / 7 and above the groove at its end, under the effect of its own weight and the spring F, enters the groove, and the rod / 7 and the supor B begin to move to the right. This is how the races of the first part of the workpiece occur, when the Suport B approaches the extreme right position and one end of the lever K uprets into the bed 2, and the other end of it pulls the dog F from the comb D.

Combs are arranged so that against the projection of one comes the beginning of the groove of the second. When the rolled product leaves the sectors 19, 20, the upper support B under the action of the spring P moves forward one pitch of the teeth, and the dies retain in this position with the pawl 3 abutting the comb. Move in the opposite direction, t. 6. go to the left end position, the workpiece passes through the second part of the processing; at the same time, support B, approaching the leftmost position, rests against the left frame 2 at one end of the lever K, and at the other end pulling the dog 3 away from the comb E, as a result of which the support 6 with the workpiece, already coming out of sectors 20, under the action of a spring P moves one step forward again, where it will be delayed with the help of the dog Z and the comb D. This advance of the upper caliper B takes place until the stop / fixed on the caliper B proves to be against the switch T, which will occur in the 3 right position caliper B.

Move to the left, support B stops up to stop T and move it to the extreme left position, and switch T squeezes lever O out of the slot in rod / 7, rod P and support B stop, and the carrier // and lever O continue to move

Then the cyriopT arm (pulled back; the rolled product is removed, the new sarofoBk V switch T is inserted by the handle Y is moved to the extreme right position, and the process is repeated) by the previous cycle.

The subject matter of the invention.

A device for automatically feeding rolled material into rolls of a sector rolling mill, characterized in that it is made in the form of two suportops A and B installed on the bed, having mutually perpendicular movement, from which the upper support B is equipped with mechanisms for holding the rolled billet and its automatic feeding the work rolls in sync with the movement of the latter, and the lower caliper L, which serves to transverse the displacement of B, receives reciprocating movement through the transmission from the working shaft lka 20.
