SU1655706A1 - Current-supplying clamp for contact butt welding - Google Patents

Description

The invention relates to weld and mortar to be used in the discharge of the 6thc-gang for contact butt welding / long-length izpelpi, for example, wire, cable core wires.

The purpose of the invention is to reduce the labor intensity of deburring by cutting: and in the diametral plane.

FIG. 1 shows a clamping current supply device, a general view, in FIG. 2 is a section A-A in FIG. one; in fig. 3 - view B on fi1 1

The device is used for welding wires from current-conducting metallogs when the technology requires a considerable length of forming devices and their electrical isolation from current-containing parts of jaws.

Each of the four jaws of the device has a current carrying part 1 and a forming holder 2, between which I will install it onto an electrical insulator 3. The outer surfaces of the jaws are formed by cylindrical surfaces of the same radius

K-pokes are used for planting the hulls of the machine (elements of the curling of the trunk are not shown) Cutting edges of knives 4 are extended with respect to edges of forming cages 2 by 0.8 mm forward along the jaws during welding

The operation of the device as part of a flash butt welding machine consists of the following.

The welded ends of the wire are laid when the sponges are open and divorced. Next, the sponges are closed. Welding voltage is applied to them and their opposite movement is ensured, which occurs before the edges touch each other. In this case, the burr is cut along the circumference (edges c) and cut into two half rings (edges b and d forming in the plane of the connector two knife pairs

The proposed design of a clamping current-carrying device for resistance butt welding makes it possible, by cutting a bur in the diametral plane, to significantly reduce the laboriousness of the deburring operation on long products.

Claims (1)

Claiming current-carrying device for resistance butt welding, comprising two pairs of detachable jaws with a shape five cages, characterized in that, in order to reduce the laboriousness of removing the bur by cutting it in the diametral plane, the device is equipped with at least two knives, each made in the form of a rectangular plate with a cutting edge, in the forming cages there are recesses in which are flush with Knives are installed by the plane of the connector, the cutting edges of the knives are offset relative to the ends of the forming holders towards each other, and bevels are made at the ends of the forming clips to exit the cutting edges of the knives.
