Machining mold and method for overlapping ''Z''-shaped bend on lightning protection belt

Abstract

The invention discloses a machining mold and method for overlapping a ''Z''-shaped bend on a lightning protection belt. The mold comprises a bottom plate, a supporting column and a molding template which is horizontally mounted on the supporting column, wherein the molding template comprises an upper mold and a lower mold which are parallel in opposite directions and are matched in a buckling manner; the lower surface of the upper mold and the upper surface of the lower mold are step surfaces; the upper surface of the upper mold and the lower surface of the lower mold are horizontal planes; the upper mold is fixedly mounted at the top end of the supporting column and the lower mold is mounted on the supporting column in a sliding manner; a limiting column is fixedly mounted on the upper mold and a lifting jack is fixedly mounted on the bottom plate; and a positioning groove is formed in the lower surface of the lower mold. The method comprises the following steps: 1, mounting the supporting frame and leveling the mold; 2, adjusting the distance between the lower mold and the upper mold; 3, determining the quantity of lightning protection belts which are machined once through the mold and placing the lightning protection belts; 4, overlapping, positioning and marking the lightning protection belts; and 5, carrying out machining and molding and checking a machining and molding result. The machining mold disclosed by the invention is compact in structure; and one or more lightning protection belts are machined by adopting the mutual effect of the upper mold and the lower mold and the machining is stable and accurate.

Description

technical field [0001] The invention belongs to the technical field of "B" bend processing, and in particular relates to a processing mold and method for lightning protection belt overlapping "B" bends. Background technique [0002] Installing a lightning protection belt on the roof of a building is an essential lightning protection project. The lightning protection belt should be made of Φ12 hot-dip galvanized round steel, and the overlapping position between the two lightning protection belts should be an obtuse angle arc. The discharge of the current will not damage the lightning protection belt. The traditional lightning protection belt lap joint "B" bend processing includes cold simmering processing method, hydraulic crimping tool matching mold processing method and hydraulic jack matching mold processing method. The simmering processing method is used to make molds, put the galvanized round steel to be processed into the mold, and manually bend the galvanized round ste...

AI Technical Summary

Problems solved by technology

However, the supporting molds in the existing hydraulic jack supporting molds are not tight in structure, weak in processing capacity, poor in stability, high in defective rate, and can only process one at a time, which cannot guarantee the rapid processing and molding of lightning protection belts.
