Description

Busbar cover cutting machine

The present invention relates to a cutting machine for cutting an insulating coating of a busbar installed on a distribution panel or a switchboard, and in more detail, the supporter grips and fixes the busbar placed on the table, and then drives the cutting unit up and down. The cutting blade is operated to automatically cut the cover of the busbar, which not only prevents safety accidents of workers, but also increases the efficiency of the cutting operation. Also, as the stopper adjusts the cutting distance of the cover, the workability is excellent while reducing the working time. It is a technology for shortening busbar coating cutting machine.

In general, the distribution panel or the distribution panel is a branch overcurrent circuit breaker collected and installed on a board, and includes a branch switch, a main overcurrent circuit breaker, a main switch, a supply and demand meter, and a current limiter. , Semi-embedded type, rainproof type, splash type, etc.

These distribution boards or switchboards install various circuit breakers and switchgear inside the enclosure to draw power from the outside and distribute it, selectively power supply, and block overcurrent.

For example, the distribution panel or the distribution panel is provided with a circuit breaker to block the current supply when an overload occurs in the distribution of main electric power input to the outside through the injection force terminal. The busbar and the charity busbar are cross-installed in the horizontal and vertical directions, and are selectively interconnected.

Here, the busbar uses a highly conductive copper or aluminum material, and is coated with an insulating film such as polyvinyl chloride resin (PVC) on the outer surface, so it is excellent in insulation of electricity discharged to the outside. Not only does it have the advantage of improving conductivity.

Therefore, in order to install the busbar on the distribution panel or the distribution panel, it is necessary to peel off the coating coated on the connection part and remove the coating coated on the busbar by using an ordinary cutting knife. There was a problem in that it was cumbersome and the efficiency was low and the risk of safety accidents followed.

As a representative prior art for easily peeling off a coating coated on a conventional busbar, Korean Patent Registration No. 10-0959370 (Busbar Coating Cutter) has been proposed.

The prior art is fixed to the lower side of the vertical fixing bar, to fix the cutting knife head to which the lower cutting knife is coupled to the fixing table, and the lower cutting knife is installed to the table to protrude upward, the table to the vertical fixing It is rotatably coupled, and an upper cutting knife is installed at a position opposite to the lower cutting knife, but the cutting knife head to which the upper cutting knife is coupled is fixed to a fixed table, and the fixed table to which the upper cutting knife is fixed is a vertical fixed table. It is to be combined with a guide and a guide holder, the height of which the upper cutting knife is fixed is the height is adjusted by the height adjustment bolt while the vertical fixing and the spring is configured to be combined.

In the prior art, when the cover of the busbar is peeled off before installing the busbar in the distribution panel, the busbar is placed on the table and moved between cutting knives, so that the worker can easily peel off by cutting the cover of the busbar. It prevents and shortens the working time.

In addition, as a representative prior art for automatically cutting and peeling a coating coated on a conventional busbar, Korean Patent Registration No. 10-1179991 (Busbar coating peeling device) has been proposed.

The prior art is an apparatus for automatically cutting and processing the covering of the busbar while operating by a press drive, a movable block installed on the press movable side and a fixed block installed on the fixed side of the press; A plurality of guide bars installed vertically connected between the movable block and the fixed block to guide the movement of the movable block; It is configured to include upper and lower cutters that are mounted to the movable block and the fixed block, respectively, to cut the upper and lower surfaces of the busbar positioned between them.

This prior art can automatically improve the workability and productivity by cutting and removing the coating coated on the busbar by using the upper and lower cutters that operate vertically in a press manner, thereby increasing the efficiency of the cutting operation.

However, in the prior art, when cutting the coating coated on the busbar with a cutting knife or a cutter, an operator grasps the busbar and performs a cutting operation, or an operator enters the busbar on the upper and lower cutters of the press to perform the cutting operation. While it is always exposed to the danger of safety accidents, there is a problem that the efficiency of work is reduced.
