Abstract

The invention relates to the design of machines for forming a loop core winding. The purpose of the invention is to improve the quality of the molding and simplify the design by influencing the forming winding on the movement of the spatial forming mechanism and matching the accelerated movement of the carriages with simultaneous rotation of the patterns. The device contains a spatial forming mechanism (MTF), comprising a lower template 5 with two curved surfaces 6 and an upper template .7 guide elements 8, on which two carriages 9 and 10, with rollers, are driven with the possibility of reciprocating movement including pneumatic cylinder, pivotally mounted on the frame, and mounts that are pivotally connected to templates 5 and 7 of the MTF. The two curved surfaces 6 of the lower template 5 limit the approach of the carriages 9 and 10 at each moment of rotation of the templates 5 and 7.

Description

The invention relates to the design of machine tools for forming a looped core winding and to be used in electrical engineering industry and in the field of electrical compression.

The purpose of the invention is to improve the quality of the molding to simplify coking by influencing the formable winding on the movement of the space forming mechanism and matching the accelerated movement of the carriages with the simultaneous 1M rotation of the patterns.

In Fig 1, an isobrshken machine, top view with partial longitudinal cuts; in fig. 2 is a section A-A in FIG. 1J in FIG. 3 is a section BB in FIG. U in FIG. 4 scheme of rotation of groove parts of the coil.

The machine for forming the loop coil of the winding core consists of a frame I, on top of which adjustable frame 2 has a frame 3 with parts of the spatial forming mechanism fixed on it. On axis 4 of the frame 3, there is a lower template 5 of the mechanism of spatial forming with f, CR-VOLUMINUM surfaces 6 and the upper template 7 "On the bed on both sides there are guide elements 8, on which, with the possibility of reciprocating movement of the fastener, two carriages 9 and 10 with rollers II. In the carriage 9, the head of the coil is fixed, and in the carriage 10 its ends are fixed.

On the carriages 9 and 10 and the templates 5 and the mechanism of spatial molding, the fixing clamps 12--14 are installed. A pneumatic cylinder 16 and two limiters 7 and 18 of the angle arm of the pneumatic cylinder 16 are attached to the base of the frame 1 on the hinge 5, Hinge pins 19 and 20 are connected with gaablons 5 and 7 between the legs 19 and 20 and the pneumatic cylinder 16 spring 2 is placed, and springs 22 are mounted on guide elements 8, plates 23 are installed in carriages 9 and 10, carriage 9 and 0 are limited to stops 24 .. Rotation of patterns 5 n 7 is carried out by means of rod 25 of pneumatic cylinder 16 installed inside spring 2 i and connected pivotally with t gami 19 and 20.

The machine works as follows.

On the wall set the workpiece made in the form of bent on reb-, 5 1) 0 elementary plate conductors, covered with fiberglass and fastened with a keeper tape. Elementary conductors fix the terminal 12-14. Place the bend billet

to is clamped in the carriage 9, the ends of the elementary conductors are laid by the meccade plates 23 of the other carriage 10. The branches of the workpiece are clamped in the lower and upper patterns 5 and 7 respectively 15, the Templates 5 and 7 and the carriages 9 and 10 are rigidly welded and all together form a closed ring B: steme.

20 In the pneumatic cylinder 16, compressed air is supplied under pressure, as a result of which the rod 25 of the pneumatic cylinder 16 is lowered, compressing the spring 21, and turning 19 and 20 rotates the forming

25 patterns 5 and 7,.,

The rotation of the patterns 5 and 7 is performed at different angles (Fig. 4) of rotation, since one branch of the workpiece is bent slightly when clamped in the upper pattern 7. The parts of the moldable part, given in templates 5 and 7, are moved apart and cause two carriages to accelerate closer by moving parts of the workpiece.

. 9 and 10, in which the bend and the ends of the workpiece are clamped. The accelerated movement of the carriages 9 and 10 is coordinated with the rotation of the patterns 5 and 7. For this, on the lower pattern 5 there are two

Q is curved surfaces 6, and rollers 1S are fixed on carriages 9 and 10. Two curved surfaces 6 of bottom template 5 limit convergence of carriages 9 to 10 at each rotational time of templates 5 and 7. This causes the moldable part to be constantly in stretched in the opposite state, which, in turn, avoids incorrect operation of the deformation pin of the coil.

The rotation of patterns 5 and 7 stops when parts of the branches of the KHj pre-set in patterns 5 and 7 are struck with molding about the corner of the stop SS 24. At this moment the carriages 9 and, 10, having gained great speed, stop the shape from two sides the rest of the coil. With his

the movement of the carriage 9 and 10 is compressed four springs 22.

After loosening the two clips 13, the carriage 5 and 7, under the action of the compressed springs 22, retract along the guiding elements 8 to the initial position, freeing the parts of the finished coil located in them. After loosening the rest of the clamps 12 and 14, the coil is removed from the templates 5 and 7, then the air is discharged from the pyro-cylinder 16 and the spring 21 compressed on the rod 25 is compressed, returns the templates 5 and 7 to its original position.
