Abstract

The invention relates to a stamping metal plate structure rope wheel for an elevator safety component and a manufacturing method. The stamping metal plate structure rope wheel comprises a disc-shapedrope wheel body, and the rope wheel body is formed by mutually stacking two supporting discs arranged in a mirror symmetry manner. A supporting cavity is formed in the middle portion of the rope wheelbody, an annular rope wheel insetting groove is formed in the outer portion of the supporting cavity, and the outer wall of the supporting cavity and the rope wheel insetting groove are connected through a plurality of connecting ribs. Each connecting rib comprises a strip-shaped protrusion cavity, and an integrated stamping structure is formed among the connecting ribs, a bowl-shaped protrusionand protruding sheets.

Description

technical field

[0001] The invention relates to a sheave with a stamped sheet metal structure used for elevator safety components and a manufacturing method, belonging to the field of elevator sheave manufacturing. Background technique

[0002] The rope sheaves used in the existing elevator safety components all adopt castings or nylon parts made of cast iron, which need to be processed through casting, aging and metal cutting.

[0003] Sheaves made of cast iron or nylon have the following disadvantages:

[0004] 1. Cast iron materials or nylon materials are used more and the cost is high;

[0005] 2. The processing is complicated, the processing cost is high, and there is a certain scrap rate;

[0006] 3. The weight is heavy, and both installation, maintenance and adjustment are troublesome, and at the same time, it is difficult to control the uniformity of the casting when it is rotating. Contents of the invention

[0007] The technical problem to be solved by the pre...
