SU112598A2 - Device for the manufacture of single-sided side rings by contact welding - Google Patents

Description

The description of the adaptation is a further improvement of the machine for the production of single-sided bicycle rings on aiBT. St. D 94895, in the “ring opener”, are prepared by joining the ends of the coupling.

The proposed device makes it possible to reduce sconce due to a defect in the manufacture of bicycle tires, improves the accuracy of finishing the sizes of the bicycle ring, significantly increasing (labor productivity). “And to lift the holozka with the help of pneumorele.

FIG. 1 shows a general view of the machine; on the f. 2-sponge electrodes with wire inserted into them.

The ring caliber 1 of the machine is equipped with a split rim, made in the form of two parts 2 and 5. Accuracy 1 zgoto: appearance. The cycle ring is achieved by the fact that the diameter of the ring caliber 1 is made up of a tension device (clamps) 4, connecting both parts 2 and 5 of the split rim, therefore the gap 5 between the parts; and the split rim is set to the required size of the ring tensioned on the ring gauge. On other co-rats of the p-rim rim, there are 6 m 7 inserts attached to them: t with electrodes S and 9 prizma.maty prefix: 1: the ends of the ring for welding. The electrodes 8 and 9 are fixed to the lifting head 10. To fix the welded joints; in the bottom; parts of caliber / mounted zazh) m 11.

The cycle ring is manufactured from patented wire, which requires tensile strength to provide the required strength of the welded joint, ne, less than 100. At the same time, it is necessary to limit the heat-affected zone, it is strictly 112598-2 -

standing, i.e., do not allow the warmed ends of the welded ring. This is achieved by the fact that the Ionians of the wire are clamped in the jaws of the electrodes tightly along the entire profile of the wire. To ensure smooth bending of the wire during welding, the jamali of the jaws of the electrodes are rounded. For precipitation of the cooling metal in the jaws of the electrodes, an uncod1I1mo is significantly greater specific pressure of the precipitation, against that in industry 5-6 kg / mm. In this case, it is applied equal to 35–40 kg / mm -, which is achieved by giving the sponges of the electrodes a form that provides a plastic support for the wire and IB points A, i.e., withstand the necessary specific pressure.
