Machines are known for forming the profile part of endless blanks from polymeric materials, for example rubber polycliner belts, containing heated profile. Parallel and co-installed slave and lead drums, Biphering ag drive and associated with the means of changing their axial distance in the process of forming the profile portion of a flat blank , with its repeated running in on the profile of the baraba: na.

Known machines do not only provide high-quality profiling of the internal noiBepxnosti endless workpieces / drive belts.

In order to eliminate this deficiency in the proposed machine, the means for changing the center distance between the profile drums are made in the form of a movable and fixed by stoppers on the rail guides of the trolley carrying the driven drum, and a drive from the drive on the rails | a drum

FIG. Figures 1 and 2 show the proposed machine in two projections; in fig. 3 - cut by L-A on fit. one; on .fi.g. 4 - section according to BB, fig. one.

The machine for forming the profile part / endless billet 2 of polymeric materials contains heated profiles.

parallel and cantilever drums, slave 3 and master 4. They rotate from drive 5 and are associated with means for changing their axial distance, made in the form of movable and fixed stoppers on the felsian guides 6 of the carriage 7 carrying the driven drum 3 and movable from a manual mechanical drive 8 or from an electromechanical drive 9 on the guides 10 of the frame 11 of the carriage 12 carrying the lead drum 4.

1 When the rotational speed of the drum 4 is not mounted 5, it is movable on the machine bed 11. The rotation of the drum 4 and the drum 3 is carried out

with the help of a Garivod 8, made in the form of a worm pair, in which one with its pods is fixedly mounted in the body of the bed 11, and the worm wheel together with the carriage 12 and the drum 4 move

along the stan | ny. // machine. The fixed position of the carriage 7 is in direct relation to the length of the profiled blank 2. To the drums 3} i 4, steam is fed to their heating by the order of 13 and 14.

The machine works The following way.

After heating the drums with steam up to the set temperature, they are put on a flat endless workpiece 2, for example a polyclip belt having a compression layer, a strength layer and an extension layer. At the same time, the cart 7 with the drum 5 is transferred, along the rail tracks 6 until the billet 2 is tensioned between the drums. In this position, the carriage is locked in a known manner, and with the help of a manual actuator 8, the workpiece between the drums is finally pulled down until its movement is eliminated. Then, the drive 5 is turned on, and the drums begin to rotate with a small number of revolutions in order to enable the workpiece to acquire stability at the beginning of its movement and fix without displacing it on the drums. At the same time, molding starts - the profiling of the inside of the workpiece. With; using a manual actuator 8 or an electromechanical actuator .9 the pastepels are changed in the direction of increasing the center distance between the drums by a double the height of the tooth to be profiled, and also increase the number of revolutions of the drums the result of repeated running of the workpiece, its teeth acquire a given profile with an exact pitch between them and with a smooth surface. After that, the machine is stopped, the workpiece is removed from the drums and, thus, the cycle of the machine is repeated.

This machine provides high-quality profiling of the outer surface of the infinite gearing of drive belts.

Subject invention

A machine for forming the profile part of endless blanks made of polymeric materials, for example rubber semi-wedge belts, containing heated profile parallel-and equid-installed driven and driving drums rotating from the drive and associated with means of changing their center distance in the forming process of the profile part flat billet, when it is repeatedly tested on profile drums, characterized in that, in order to ensure high-quality profiling of endless billets of driving gears it, means for altering the interaxial spacing between the profile reels are designed as a movable and lockable on fiyusiruemoy guide rail bogie carrying the driven drum and movable by the actuator to the carriage guide frame with the driving drum.
