Description

Technical Field:

[0001] The present invention relates to the technical field of junction box processing equipment, and more specifically to a rotary feeding and discharging device on a punching device for the hole positions of a junction box. Background Art:

[0002] A junction box is a commonly used electrical accessory that facilitates the connection of wires and protects the wires. Currently, junction boxes are made of various materials or metals, and installation hole positions also need to be processed on the junction box. Generally, the installation hole positions on the current junction box are not directly punched, but there are circular baffles inside the hole positions. Several contact points are formed on the outer circle of the baffle and are connected to the junction box. When the junction box is specifically used, the corresponding hole positions can be used by removing the baffle, and other different hole positions can be blocked by the baffle. Therefore, when specifically processing the installation hole positions, a circular cutting groove is cut by punching, and the cutting groove also has multiple break points, that is, multiple arc grooves evenly distributed in a ring shape are cut. During the cutting process, a positioning support base for effectively supporting the junction box is required to prevent the overall depression of the junction box during punching;
