Embodiment Construction

[0034] Hereinafter, the traveling vehicle of the present invention will be described. The present invention is a traveling trolley equipped with a torch such as a cutting torch or a welding torch, and used when cutting or welding a workpiece represented by a steel plate (hereinafter referred to as "steel plate"). In particular, it is configured to be able to reliably perform the process of starting or terminating cutting from the end face of the workpiece, piercing the workpiece and then continuously cutting from the piercing point, or starting welding. when processing, or when terminating welding.

[0035] A torch for gas cutting, a torch for plasma cutting, and the like can be selectively adopted as the torch for cutting the steel plate mounted on the traveling carriage. In the gas cutting torch, it is connected to the fuel gas supply device and the oxygen supply device through a plurality of hoses. In the plasma torch, it is connected to the power supply through a double-c...

Abstract

A traveling truck can facilitate operations performed when starting and ending machining of a machined material. A traveling truck A has: a drive motor 25; a three-position selection switch 12; a press-button switch 13 for enabling travel at a preset secondary speed; a speed setting dial 14 for setting a machining speed or the secondary speed; and a control unit 20 that stores the machining speedand the secondary speed in accordance with the operation amount of the speed setting dial, controls the rotational direction and the rotational speed of the drive motor in response to a travel signalfrom the three-position selection switch, and controls the rotational speed corresponding to the secondary speed while holding the rotational direction of the drive motor when a secondary speed signalis generated from the press-button switch and the secondary speed signal is maintained.

Description

technical field [0001] The present invention relates to a traveling trolley capable of reliably performing a processing start operation or termination operation when cutting or welding a workpiece with a mounted torch. Background technique [0002] A traveling trolley is used, which is equipped with a torch such as a gas cutting torch for cutting the material to be processed, a plasma torch, or a welding torch for welding the material to be processed, and is driven while operating the torch. Cutting or welding of processed materials represented by steel plates. When using a torch mounted on a traveling trolley to cut or weld a workpiece, the cutting speed or welding speed depends on the thickness and material of the workpiece, the roughness of the cut surface, and the thickness of the weld bead. Specification conditions are set accordingly. However, when the workpiece is cut or welded, the workpiece is in a normal temperature state, and target processing cannot be started ...
