One-time forming tool for cross arm holding iron

Abstract

The invention discloses a one-time forming tool for cross arm holding iron. The one-time forming tool comprises a base and a mold fixed to the base. The mold comprises a profiling mold body and a forming pressing plate. The forming pressing plate comprises a connecting lug, a pressing plate body and a pressing rod connecting piece. The connecting lug is connected to one end of the pressing plate body, and the pressing rod connecting piece is connected to the other end of the pressing plate body. The top face of the profiling mold body is a circular arc face. One side of the circular arc face is an inclined plane, and the other side of the circular arc face is a groove. A pin shaft hole is formed in the profiling mold body. The central line of the pin shaft hole coincides with the central line of the circular arc face. The connecting lug of the forming pressing plate is hinged to the profiling mold body through a pin shaft. The pin shaft is fixed in the pin shaft hole of the profiling mold body. The two ends of the pin shaft extend out of the pin shaft hole to be connected with the connecting lug of the forming pressing plate. According to the one-time forming tool, the triangular holding iron is formed through one-time pressing and forming of flat iron, the lever principle is applied ingeniously in the forming process, time and labor are saved, the machining efficiency is high, the specifications of the machined holding iron are unified, and consistency is good.

Description

technical field [0001] The invention relates to a mechanical processing tool, in particular to a one-time forming tool for holding iron with a cross arm. Background technique [0002] Cross-arms are often used on poles of low-voltage lines. However, the contact area between ordinary cross-arms and poles is very small, and the fixation is not firm. The contact area of ​​the rod makes the cross arm fixed firmly and reliably. The holding iron is a triangle iron welded upside down on the cross arm. Since there is no uniform production specification for iron holding in the industry, the manufacturing methods are also varied. Some simply cut a section of angle iron and weld it directly on the cross arm; some make molds, heat the flat iron and bend it with a punching machine, and then weld it after forming. The former has the same height on both sides of the produced iron embracing, so the combination of the cross arm and the pole is not tight, and it is difficult to maintain the...

AI Technical Summary

Problems solved by technology

The former has the same height on both sides of the produced iron-holding, which leads to the loose connection between the cross-arm and the pole, and it is difficult for the cross-arm to maintain a horizontal position, which affects the appearance of the line, is not standardized, and has many potential safety hazards

The latter's manufacturing method is complicated in procedure, inefficient and high in cost
