ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a welding device, and more particularly to a welding device for net members.
2. Description of the Prior Art
Typical nets comprise a number of wires arranged cross to each other and required to be welded together at the joints. The wires of the typical nets may not be welded and secured together quickly.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional welding devices for net members.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a welding device for quickly welding the wires into the net member.
In accordance with one aspect of the invention, there is provided a welding device comprising a base, a plurality of welding members provided on the base, a frame for supporting a plurality of wires to be welded together, means for moving the frame between the welding members, and means for actuating the welding members to weld the wires together, such that the wires may be quickly welded to form the required net members.
The base includes means for slidably supporting the frame in the base. The supporting means includes a pair of tracks disposed in the base for slidably supporting the frame. The tracks each includes a plurality of rollers provided thereon for engaging with the frame.
The moving means includes a belt slidably received in the base, means for moving the belt, and a clamping device disposed on the belt and movable in concert with the belt for clamping the frame and for allowing the frame to be moved by the belt moving means via the belt and the clamping device. The frame includes a handle, the belt includes an actuator secured thereon, the clamping device is secured to the actuator.
A device is further provided for removing the wires from the frame and includes a table slidably received in the base, a removing member disposed on the table, means for moving the table up and down to remove the wires from the frame.
A device is further provided for guiding the table to move up and down relative to the frame. A device is further provided for preventing the table from rotating relative to the frame.
A device is further provided for elevating the frame and includes a pair of slides, two actuators disposed on the slides respectively and each having a piston rod extendible to engage with the frame and to retain the frame in place, and means for moving the slides up and down to move the frame up and down. The elevating means includes a pair of brackets slidably supported in the base and each having at least one rail extended therefrom for slidably supporting the slide respectively. The base includes a pair of tracks disposed therein for slidably supporting the frame, the tracks each includes at least one depression formed therein for slidably receiving the piston rod of the actuator respectively.
A second frame is further provided for slidably supported in the base for supporting wires to be welded together and for moving the wires between the welding members.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow with appropriate reference to accompanying drawings.
