The present invention relates to a wire feeder device for a welding machine, and more particularly, to a technology that makes it easy to replace the work in the event of failure of various parts or products in the wire feeder when working in the field.

In shipyards or other heavy industries, on-site welding is a very important task in determining product quality. In general, CO2 gas welding machine is mainly used for welding.

Figure 1 schematically shows the overall structure of a general CO2 gas welder, which consists of a welding power source 1, a single cable (2), a wire feeder (3), a welding torch (4) and a protective gas cylinder (5). The circuit (control box) for controlling the feeding motor of the wire feeder 3 is generally mounted on the wire feeder 3 adjacent to the welding worker for the convenience of use.

The CO2 gas welding machine having such a structure normally supplies DC power, control power, and protective gas to the wire feeder 3 through the single cable 2 in the welding power source 1 and the protective gas cylinder 5, and the wire feeder 3 It is possible to control the supply state and the power supply of the welding wire and the protective gas supplied from the control box 3a of the control panel 3a to the welding torch 4.

Specifically, the wire feeder for the conventional welding machine will be described in detail. As shown in FIGS. 2 and 3, as many as 10 strands of wires from the control connector 3b of the main body of the wire feeder 3 to the control box 3a are provided. Control cable 3c is connected, and separate connection lines 3g from the control box 3a to the gas valve 3d, the wire feeding motor 3e, and the torch connector 3f are individually and intricately wired. there was.

In the conventional wire feeder, the control connector 3b is exposed to the rear of the wire feeder 3 so that the control connector 3b easily collides with another object during use and movement thereof, or the control cable 3c is disconnected or Short circuit has been a cause of failure or electric shock, and disconnection and poor contact of more than 10 strands of the control cable 3c connecting the control connector 3b of the main body of the wire feeder 3 and the control box 3a. Control cable 3c and variously complicated wirings inside the wire feeder 3 to replace the defect of the wire feeder due to the wiring of the complicated connection lines 3g and the failure of the control box 3a. The connection lines (3g) had to be disconnected, and when replacing a new control box, this complicated wiring and soldering work had to be redone.

In order to solve these shortcomings, a wire feeder conventionally proposed is disclosed in Korean Registered Utility Model Publication No. 20-026909 (Registration Date: Jan. 18, 2002). 4 is a perspective view disclosed in the above publication, and FIG. 5 is a front view of FIG. 4.

As shown in FIGS. 4 and 5, the wire feeder improved in the related art is a welding machine wire feeder 30 in which a control box 31 is installed, and the control connector 32 and the torch connector are connected to the control box 31. (33) and a wire connector (30) by attaching a connection connector (36) for wiring to the gas valve (34) and the feeding motor (35) so that various wirings, including the control cable (37), can be connected thereto. It can eliminate the complicated connection line from the main body to the control box 31 to reduce the failure rate, eliminate the disconnection and the complexity of the wiring, and in case of failure of the control box, replace only the spare control box so as not to interfere with the use of the welding machine. It is.

However, this method also attaches only a connection connector to the control box and connects various wires to the connection connector, so that a plurality of wires are connected to one connection connector, so that the failure of the connection connector can be frequent. Will occur. In addition, when replacing a new control box, the separation from the wire feeder has not been greatly improved, and as the control box is installed obliquely on the upper part of the wire feeder, stability cannot be guaranteed. On the other hand, as the gas outlet adapters 38 and 39 are connected to the wire feeder main body, the inconvenience of having to repair the wire feeder itself in case of failure of the gas outlet adapter or failure of the solenoid valve continues to occur. Considering that the failure rate of the solenoid in the feeder device is very high, there is a problem that the replacement work due to the failure is not substantially improved.

The present invention has been made to solve the above problems and disadvantages, and an object of the present invention is to provide a wire feeder device to be easily attached and detached to the wire feeder.

Another object of the present invention is to provide a wire feeder device having a control box to simplify the structure of the wire feeder main body as much as possible.

Still another object of the present invention is to provide a wire feeder device that facilitates troubleshooting as much as possible by implementing a part that can easily or frequently occur in a control box as much as possible.

Still another object of the present invention is to provide a wire feeder device which facilitates troubleshooting by implementing a gas inlet / outlet adapter or a gas nipple in a control box.

Another object of the present invention to provide a wire feeder device that maximizes the installation stability of the control box.

The present invention for achieving the above technical problem is a body frame equipped with a motor and a wire mount; A portable control box coupled to the pedestal portion of the body frame and including at least a connecting connector and a gas nipple; And it is characterized in that the wire feeder device comprising a connecting means to be detachable between the body frame and the portable control box.

The body frame is characterized in that it comprises a motor formed on one side on the pedestal, a reel shaft formed on the pedestal, and a wire mount connected to the reel shaft.

The portable control box includes a control cable connector to which a control cable is connected, a torch switch connector to which a torch is connected, a gas nipple, and a solenoid valve connected to the gas nipple. Preferably, the control cable connector is implemented with a 9-PIN connector. Also preferably, the torch switch connector is implemented with a 2-PIN connector. The gas nipple is formed on both sides of the portable control box at the same time, the gas nipples of both sides are connected by a flexible pipe inside the portable control box, to facilitate the replacement operation. The portable control box includes a current knob, a voltage knob, a gas check switch for checking gas, and an inching switch for advancing a welding wire from the wire feeder to the torch little by little. In addition, the upper surface to form a handle.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

6 is a schematic view showing an embodiment of a wire feeder main body constituting the wire feeder device according to the present invention.

The wire feeder main body of FIG. 6 includes a body frame 100, a motor 110 installed on one side of a pedestal 100-1 of the body frame 100, and another pedestal 100-1 of the body frame 100.
