Anti-drop power plug and socket assembly for material bending machine

Abstract

The invention relates to an anti-drop power plug and socket assembly for a material bending machine and belongs to the technical field of material bending machines. The anti-drop power plug and socketassembly for the material bending machine comprises a plug; the bottom of the plug is fixedly connected with two symmetrical insertion pieces; electromagnets are fixedly connected to the inner wallsof the tops of the insertion pieces; resistors electrically connected with the electromagnets are fixedly connected to the inner walls of the inner sides of the insertion pieces; negative plates electrically connected with the resistors are fixedly connected to the inner walls of the inner sides of the insertion pieces. According to the anti-drop power plug and socket assembly for the material bending machine of the invention, a rubber film and a limiting groove are matched for use; when the plug is pulled vigorously by an external force, the plug can quickly move upwards under the action of external force, large centrifugal force is generated, so that a piston block moves downwards and extrudes an electrorheological fluid; the rubber film is extruded and expanded by the electrorheologicalfluid; and the rubber film is clamped with the limiting groove, so that the effect of limiting the plug from falling off is achieved, electric power stable connection of the material bending machineis guaranteed, and normal work of the material bending machine is guaranteed.

Description

Technical field [0001] Technical Field The present invention relates to a koji machine, particularly as a koji machine fall preventive power plug and socket. Background technique [0002] Real life, there are many places the need for sheet metal cutting, sheet metal cutting not only the type of variety, and the type of curve to be cut are also a variety of multi-class, while requiring a simple, flexible and convenient and economical, these materials most of the cutting device is achieved through the power of work, work to achieve through the power socket and plug electrical power connection, but the current power socket and power plug frequently encounter some problems in the course. [0003] At present, most of the power plug and the power outlet is connected by way of plug-together, but often electric power socket and plug the power shedding will occur during use, resulting koji machine suddenly disconnected power, leading to a sudden interruption of work, influence production ...

AI Technical Summary

Problems solved by technology

[0002] In real life, there are many places where sheet metal cutting is required. Not only are there various types of sheet materials to be cut, but there are also various types of curves that need to be cut. At the same time, it is required to be simple, flexible, convenient, economical and practical. These materials Most of the current cutting equipment works through electricity, and the work is realized through the electrical connection of the power socket and the power plug, but the current power socket and the power plug often encounter some problems during use.

[0003] Most of the current power plugs and power sockets are connected together by plugging, but the power sockets and power plugs often fall off during use, causing the bending machine to suddenly disconnect the power, resulting in a sudden interruption of work, affecting Production efficiency, at the same time, it may cause damage to the bending machine, shortening the service life of the bending machine
