DE2351800A1 - Method of making bearing bushes - comprises parting individual bushes from tube produced by helically winding tape around mandrel - Google Patents

Abstract

The tape is made of plastics covered metallic weave e.g. gauze, and is helicaly coiled around the mandrel to produce the tube. The adjacent edges of the wound tape are soldered together on the mandrel. Individual lengths of the tube are parted off by an appropriate parting tool to form the individual bushes. Soldering is continuousl.

Method for manufacturing bearing bushes from with Plastic coated metal mesh

The invention relates to "a method of manufacturing of bearing bushes made of metal mesh coated with plastic. Such sockets are usually made from individual pieces on an automatic bending machine. The bending machines are extremely expensive and complicated. The magazining However, the individual pieces cause difficulties because they often get caught up in one another. The subsequent soldering of the joints also requires considerable effort. Even automation is hardly possible here. '

The object of the invention is therefore the production of bearing bushes from plastic coated metal mesh through mechanical

to simplify nization and make it cheaper while improving quality at the same time. aside from that the tolerance of the inner diameter of the bearing bushes produced is to be narrowed.

According to the invention, this is achieved by the following manufacturing process achieved:

the production of a strip of coated metal mesh,

the manufacture of a tube by helically winding this tape onto a core with continuous soldering of the two adjacent ones Butt edges, and the cutting off of pipe sections in the required length.

The continuous soldering can be carried out by a known method.

Depending on the intended use of the bearing bushes, the joints can be the same after soldering are also coated with plastic, either already on the pipe or else only after parting.

The method according to the invention is illustrated schematically in the drawing.

It shows a drum 1 with a fabric tape 2 wound thereon. This is wound onto a core 3 in a helical manner. The abutting edge h is then continuously soldered, which is symbolized by a flame 5. is sated. At the end of the core 3, pieces of pipe are cut to the required length. The parting device is illustrated by a parting tool 7.

In this way a continuous production of bushings is possible. Even winding on a core means that the Diameter tolerances reduced compared to the conventional one, a substantial reduction in price occurs through the achieved simplification of production.

Should a plastic coating also the soldered Butting edge may be required, this can be done during continuous production the bushings either on the pipe or on the bushing that has already been cut.
