SU116230A1 - Packaging mechanism for the device for the automatic manufacture of the cores of electrical machines, apparatus and transformers - Google Patents

Description

In devices for automatic grinding of the cores of electrical machines, apparatuses and transformers, mainly from tape, it has been proposed to use packing machines comprising a turntable with mandrels for assembling the sheets into bags and a press for leading sheets onto the mandrel.

The proposed mechanism is more perfect, since it automates the process of picking cores. This is achieved by providing a spring-loaded support for axially movable mandrels along the axis of the press punch, which is provided with an electrical contact device that operates when the package reaches the required height and controls the table rotation mechanism.

The drawing shows a diagram of the proposed mechanism.

The tape / magnetic steel (or strip) with the aid of known devices enters an automatic press 2, where a corresponding part is cut from it, for example, a stator sheet with all the slots. However, separation of the cut-out part from the sheet (or strip) is not carried out and they remain connected by means of a web or by pressing the cut-out sheet back into the cutting hole.

In this form, the tape (or strip) moves to the packaging mechanism. If necessary, a tape with parts may preliminarily pass through a device for removing burrs li a thermo-annealing furnace (not shown in the drawing).

In the packaging mechanism, the punch 3 finally separates the cut sheet from the tape (or strip) and, with the same stroke, cuts the cut part onto the mandrel 4.

After a series of repeated strokes, a predetermined (in thickness) number of parts is mounted on the mandrel 4, the force of the punch fitting the last part is sufficient to compress the entire package and feed it together with the mandrel 4 down where a special contact device is placed 5. When the contacts of this device are closed, a solenoid valve 6 is turned on, which actuates the piston 7, turning the table 8 of the buncher mechanism by one pin. In this case, the mandrel 3 is fed under the punch, and the mandrel with the filled package is moved to the free zone, from where the bag is sent for further processing.

Subject invention

A packaging mechanism for a device for the automatic manufacture of cores of electrical machines, devices and transformers, preferably of a belt, comprising a turntable with mandrels for assembling sheets into packages and a press for supplying sheets to the mandrel, characterized in that, in order to automate the process of completing cores , on the axis of the press of the press is located a spring-loaded support for axially movable mandrels, equipped with an electrical contact device, which is triggered when The Ket requires the desired height and controls the table rotation mechanism.
