Description

The invention relates to the field of mechanical engineering, in particular to devices for winding long material such as wire or ropes into coils.

The purpose of the invention is to improve the quality of the wire frame spool.

Improving the quality is achieved by reducing the labor required to manufacture individual brackets, simplifying assembly technology and increasing the productivity and rigidity of wire spools.

Reduced labor costs are due to the fact that manual labor is used only when bending the lower braces, and when assembling it is necessary to weld fewer individual brackets. In a known design in a simple way (without the use of automatic machines) can be made

only billets - measured straight pieces of wire for subsequent bending already using manual labor of the lower straight sections and bent ends. Moreover, one machine is needed for bending the lower straight sections, and the second for bent ends; therefore, two workers are needed to make the individual brackets.

During assembly, a reduction in manual labor takes place, since the centering of the individual brackets in the conductor is simplified due to their volumetric shapes, in addition, fewer welding points and fewer individual brackets are required. Since the amount of labor is reduced, productivity is therefore increased.

The technology for manufacturing individual brackets and bobbin assembly is simplified because

when bending extreme rectilinear sections, the flat shape of the workpieces of the individual brackets ensures their centering in the bending device, and during assembly is simplified, since the volumetric shape of the individual brackets facilitates and increases the accuracy of the installation of individual brackets in the welding conductor.

The rigidity of the wire frame spool is increased due to the fact that a significant part of the overall rings consists of two wires. This reduces the likelihood of disturbances in geometric shapes.

The goal is achieved. that in a wire frame spool containing two parallel dimensional rings and separate staples of the shape of the letter P in the view of the charging part, the rectilinear middle sections of which are ordered along the cylindrical surface and form the core of the spool, and the extreme rectilinear sections - its flanges, are separate the bracket has the shape of an inverted letter P with middle curved sections in the view of the end of the spool, is equipped with at least two rectilinear middle and two curved middle sections, and is rigidly connected, for example using welding, curved middle sections evenly around the circumference of the dimensional rings, each of which is made of one piece of wire bent into a hoop.

The outer radii of the curved middle sections of the individual brackets are equal to the inner radii of the overall rings.

In FIG. 1 shows a general view of a wire frame spool, a perspective view; in Fig.2 - a separate bracket (view of the bracket in arrow A in Fig. 1); on ig. 3 is the same {view along arrow B in FIG. I or along arrow B in FIG. 2); in FIG. 4 - a separate bracket obtained after winding and cutting (blank for stamping a separate bracket).

The wire frame spool contains two flanges 1 and 2, each of which is made of one piece of wire, and individual brackets 3. having the shape of a rectangle. Each individual bracket is made of a separate piece of wire and has at least two middle rectilinear sections 4, which are arranged along the cylindrical surface and form the core of the spool, lower rectilinear sections 5 form flanges, and middle curved sections 6 (in the form of the inverted letter P ) are made along arcs with a radius equal to the radius of the inner surface of the dimensional rings 1 and 2.

The middle curved sections 6 separate brackets 3 evenly around the circumference are rigidly attached to the dimensional rings 1 and 2, for example, by welding.

In the manufacture of dimensional rings 1 and

2 and oval reamers 7 (blanks for stamping individual brackets) wind the wire onto round and oval respectively, having internal dimensions

dimensional rings 1 and 2 and reamers 7 drums, and then cut into generators, dimensional rings 1 and 2 are fed to the assembly, and for oval reamers 7 along the lines Г-Г and Д-Д the lower braces 5 are bent along with

middle curved braces 6 and served on the assembly.

The number of welding points during the assembly of wire frame spools can be one or two in one middle curved section 6, depending on the requirements of reliability, rigidity and installation locations of sections of wire rings 1 and 2 and individual brackets 3 ..

The wire frame spool made in this way allows to improve the quality by increasing its rigidity, increasing reliability, and simplifying the manufacturing method.
