Detailed Description

The invention is described in further detail below in connection with the accompanying drawings.

As shown in fig. 1, 2, 3 and 4, the electric metal threading pipe bending apparatus sequentially comprises a base 8, a workbench 1 and a bending pipe bearing from bottom to top, wherein a clamping cavity 15 is arranged on the base, a clamping head 14 is arranged at the lower end of the workbench, the bending pipe bearing comprises an inner ring 3, a rolling body 5 and an outer ring 2, the inner ring is fixedly connected with one end of a horizontally arranged support plate 11, the other end of one end of the support plate is supported on the base through a pillar 13, a backup plate 10 perpendicular to the support plate is connected on the support plate, moving grooves 20 are arranged on two sides of the support plate, a moving bottom rod 18 at the lower end of the backup plate is arranged in the moving grooves, the front end (the right end in fig. 4) of the moving bottom rod is abutted against the front side of the moving grooves through a buffer spring 19, the rear end (the left end in fig. 4) of the moving bottom rod is fixed through an adjusting bolt 17, the outer ring is characterized in that an outer bending column 7 is fixed on the upper portion of the outer ring, an operating rod 6 is fixedly connected between the outer surface of the outer ring and the lower surface of the outer bending column (when each part is made of steel, iron and the like, the fixed connection can adopt a welding mode), and in order to reduce the deformation of the bending part of the metal feed-through pipe during the pipe bending operation, pipe bending grooves 16 are formed in the inner bending column and the outer bending column.
