Description

Machine tools for stamping a blank in the form of two rollers, "s KOiotorykh", carrying replaceable stamps, are placed on a slider for hauling to the workpiece, the driving direction of which is used to rotate the roller, are already known.

The main feature of the proposed machine for the same purpose is that the roller bearing the stamps is made in the form of a fist with a large radius at the place of installation of the stamps, in order to increase the pressure at the time of glue | M eni.

FIG. I depicts a general view of the proposed machine; “And FIG. 2 shows a section along ab in FIG. one; in fig. 3 is a section along cd in FIG. one.

On the frames of the roller table, on which the workpiece 2} is transported from the mill to the refrigerator, a machine bed is installed consisting of two cast racks 1, fastened with the paMtaMH roller table with bolts, and each other with straps 2.

Traverse 3, mounted in guide posts 1, can be moved therein by means of worm gears 4.

In parallel with the traverse 3, a slider 5 slides suspended from the traverse on two spring-loaded bolts 6.

five

The raising of the slide 5 upwards is limited by a stop screw 7 fixed in the traverse 3 on the spring 8, the tension of the brand is adjusted to the tension of which.

In Slider 5 roller roller rotates roller 9, made in the form of a fist, stamps 10 are mounted in the caster. From the sides of roller 9 there are two stoppers 11, which, when roller 9 is in the upper position, abut 1c in two rods 12, freely passing through the slider 5 and rigidly fixed in traverse 3.

The extension of the stamps 10 from the roller 9 is carried out either by springs placed in pin 9 or by turning the eccentric rod 180 °, also placed in the roller.

In order to prevent the stoppers 11 from striking the rods 12 and to cancel the roller moment of Roller 9, when it was stopped, a shock absorber 13 was installed on the side of the slide 5, consisting of two flat steel arcs and two springs with pins.

On bolts 6, a balancer 14 is mounted on top, in which a roller is attached, which is in contact with lever 1.m 15, rotating in bracket 16, mounted on the machine cross-arm.

On the bracket 16, there is an electromagnet 17, the measles of which is connected to the other KOiHUOiM lever 15.

Ralik 18 of the charcoal-type conveyor wheel is connected with an IB scar: 19, which carries an electric coupling.

20, the free disk of which is attached to the hinge shafts with the roller shaft 9.

Switching the electromagnetic clutch on and off 20 ISOLATED)

simultaneously with the switching off and switching off of the electromagnet 17.

Beveling 21 after leaving the mill and after cutting with scissors passes through the machine and, as soon as the limit switch 22 rises to its upper position after passing the end of the workpiece, the electromagnet 17 is turned on. At this, the slider 5 goes down and the stopper 11 comes out of the engagement and roller 9, contacting with the workpiece

21, starts vrash, ats.

Roller 9: P; p rotates "in the first quarter of the circumference, due to the eccentric surface, at the same time, P | rides rise to its upper position, then on the second quarter of the circumference it rolls along the workpiece;

Subject matter

A machine for stamping a hot workpiece iB in the form of two rollers, one of which, a replaceable stamp, is placed on a slider to be fed to a workpiece whose motion is used for B: a roller, characterized in that the carrier 9 bearing the roller 9 is made in a fist with the most radius) M at the installation site of 1O1m, in order to increase the pressure at the moment of the branding.
