Abstract

A spool for wires or codes made of metal, plastic or the like, and particularly welding wires. It has single-piece segments, each forming a U-shaped support yoke with a cross bridge and legs. This yoke extends inwardly in radial planes, its free leg ends having the extensions extending in the circuferential direction, and the extensions, joined together, form two parallel wire rings. Two symmetric wire parts are fastened on the radial legs for forming a hub on both sides of the segment, whereby a wire part on both sides of hub ring segment has a part with a bent extension leg. This part extends the legs against the spool center and reaches up to the spool diameter. In their transition zone into the hub ring segments, the wire parts are connected with each other, whereby the plane established by the connected wire parts coincides with the plane established by the wire rings and the legs.

Description

Be used to restrict or the rolling wheel of line

The present invention relates to the rolling wheel that rope or line, especially welding wire that a kind of metal, plastics etc. make are used.This rolling wheel has a plurality of integral component, its each in the sagittal plane inside curved stretching and form a U-shaped coil holder.The free end of this all legs have the prolongation that stretches out at circumferencial direction and each other frame together to form two parallel wire loops.

DE2503567C2 discloses a kind of known rolling wheel, and it can connect together all assemblies and simply and cheaply created by a small amount of solder joint.Adopt this rolling wheel, the crossbeam between the U-shaped coil holder leg formed be used to treat around the support of line, promptly formed around the heart by these crossbeams.When around the diameter of the heart and rolling wheel center hub than after reaching certain amplitude, use joint, it can make rolling wheel be inserted in the rotating shaft of a coupling.

In addition, DE2814057A1 also discloses a kind of rolling wheel, and it is assembled by a plurality of independently integral component, and thus, these assemblies had both formed the diameter around the heart, has also formed the diameter of rolling wheel center hub.But the shortcoming of these known rolling wheels is: all assemblies that form spool need four solder joints to connect two such parts.Become difficult because the solder joint present position is arranged solder joint, therefore need more complicated welding gear.In addition, the design of assembly has caused the increase of material consumption.And for stablizing this structure of reason and be not suitable for bigger rolling wheel, so it also is disadvantageous.

An object of the present invention is to overcome the shortcoming in the prior art, and provide a kind of can cheaply be made through improved rolling wheel, it has a rolling wheel center hub diameter that reduces, and comprises the joint that a same material that uses with the rolling wheel remainder is made.

According to the present invention, realized this purpose thus: the line member made of at least two symmetries is fixed to the radial leg frame to form a propeller boss on two sides of assembly, thus, provides a line member made on each of nave collar assembly.The prolongation leg of this line member made by a bending stretches to the center of rolling wheel from all leg framves portion.The line member made connects in the bonding pad each other to form the nave collar assembly, and thus, the plane that connected line member made is set up overlaps each other with the plane that wire loop and leg frame are set up.

According to another embodiment of the present invention, each assembly has a step (intensification) to accept relevant leg frame at coupling end.

In another embodiment, the end of prolongation prolongs radially and curves inwardly, so that all ends extend with the leg frame of next assembly in each case with paralleling.All ends for example join by spot welding and described leg frame rigidity.

In addition, in another embodiment, prolongation stretches out in the opposite direction.

The present invention has following advantage: promptly by the simple modification to known rolling wheel, can produce a kind of rolling wheel that the rolling wheel center hub is arranged.And this has produced stable and simple structure, and this structure can easily be created, because it is based on a kind of design of checking.Moreover, this rolling wheel also has additional advantage: it is environmentally friendly, because it only comprises iron wire, therefore can be recycled fully.

From the following detailed description that discloses the embodiment of the invention, and with reference to the accompanying drawings, purpose of the present invention and feature will become apparent.But, be appreciated that accompanying drawing only for illustrative purposes designs, be not as qualification to protection domain of the present invention.

In the accompanying drawings, run through all views, identical reference character is represented components identical.

Fig. 1 is the front elevation according to an embodiment of rolling wheel of the present invention;

Fig. 2 is the cutaway view along A among Fig. 1-the A line is got;

Fig. 3 is the transparent view according to two rolling wheel assemblies of another embodiment of rolling wheel of the present invention;

Fig. 4 is the transparent view according to two rolling wheel assemblies of another embodiment of the present invention; And

Fig. 5 is the transparent view according to two rolling wheel assemblies of another embodiment of rolling wheel of the present invention.

Introduce accompanying drawing now in detail.Fig. 1 shows assembly 1, its each by crossbeam 3 and a pair of coil holder that has formed a U-shaped at radially-protruding leg frame 4.The free end of leg frame 4 is connected to the parallel prolongation 2 of the bending that forms the rolling wheel neighboring.By a kind of like this method: i.e. the prolongation 2 and each leg frame 4 monolithic molding of each U-shaped coil holder, and in an algorithm, produce each assembly 1.Inwardly the depression that extrudes or cave in 5 is formed between each prolongation 2 and the respective leg frame 4, to accept adjacent shank.Crossbeam 3 has formed the rolling wheel cooling diameter of winding rope on it or line.

Therefore, this rolling wheel can be contained in the rotating shaft, and propeller boss 6 is formed by the line member made 8 of two symmetries.Line member made 8 is contained on the leg frame 4 in the rolling wheel both sides.In an illustrated embodiment, rolling wheel has eight assemblies 1, the staggered relatively several common diameter of leg frame 4 along annulus is distributed.Line member made 8 has radial extent spare 12, and this elongate member has the leg frame 13 that transversely stretches out certain angle, leg frame and annulus assembly 7 monolithic moldings.The annulus assembly 7 of hub is connected with each other along rolling wheel diameter 14.Two line member mades 8 all are approximate M shapes, and parts 12 are soldered to leg frame 4, and leg frame 13 is along they contact level solder togethers on rolling wheel diameter 14.In addition, line spare parts 8 are fixed with a kind of like this method: promptly they are not outside rolling wheel has transverse projection (Fig. 2) and is distributed in rolling wheel plane 18a and the 18b.Fig. 1 shows in the arrangement of leg frame 4 upper-parts 12 separately, and the connection of 15 interior lines member mades 8 in the bonding pad.A line member made 8 is inverted in the top of another line member made 8.By this method, the annulus assembly 7 of hub, promptly two of M peak-to-peak radius curve have formed propeller boss 6.

In second embodiment according to Fig. 3, the end of prolongation 2 19 little inwardly curved and with adjacent component 1 ' leg frame 4 dock.But at other aspect all, assembly 1 ' mode similar to assembly 1 among Fig. 1 and 2 formed.

In the 3rd embodiment according to Fig. 4, the end of prolongation 2 21 little inwardly curved and with adjacent component 1 " leg frame 4 extend abreast.22 places in the position, in terminal 21 with leg frame 4 between carry out spot welding and be connected.For example, terminal 21 align with the parts 12 that extend radially out of leg frame 4 sides.

At last, show assembly 1 according to Fig. 5 fourth embodiment of the present invention with the prolongation 2 that in the opposite direction stretches out.According to the embodiment of Fig. 4, carry out the connection between adjacent component 1 .

Even illustrate and introduced several embodiments of the present invention, be appreciated that and make many variations and modification, and do not depart from spirit of the present invention and the scope that claims limit this.
