Description

A precision punching device for elevator flywheel housing processing

Technical Field

The utility model relates to the technical field of elevators, in particular to a precision punching device used for processing an elevator flywheel housing.

Background Art

The shape of the elevator flywheel housing is usually a disc or cylinder, depending on the design and manufacturer of the elevator. Generally speaking, the outline of the flywheel housing is relatively simple to meet the requirements of the elevator suspension system. There are usually some holes or notches on the side of the flywheel housing for installing other components such as suspension wire ropes and guide wheels;

In addition, the size and weight of the flywheel housing will also be designed according to the specifications and performance requirements of the elevator. Generally speaking, the flywheel housing is smaller in size and lighter in weight to reduce the energy consumption of the elevator and improve the operating efficiency;

In the process of processing the elevator flywheel housing, there is a step of punching a hole in it to facilitate the subsequent assembly. A punching device is needed for punching. However, there are still some problems in the use of traditional punching devices. Since the shape of the elevator flywheel housing is usually a disc, the traditional two-side clamping method is prone to slipping during the punching process, resulting in punching failure. Therefore, a precision punching device for elevator flywheel housing processing is needed to solve the above problems.
