Embodiment Construction

[0037] The purpose of the present invention is to provide a precise current loading device and a precise current loading method.

[0038] Below in conjunction with accompanying drawing, the present invention will be further described:

[0039] Such as figure 1 The current accurate loading device of the present invention shown includes a total support 2, two clamping devices 8, an induction coil 16, an upper connecting rod 11, a temperature vision camera system 12, a sliding subsystem, a computer processing terminal 1 and a pulse current subsystem.

[0040] The total bracket includes a frame, a side bracket and an upper bracket. A sliding groove parallel to one side of the frame is fixedly installed on the bottom of the frame. The sliding groove can ensure the smooth movement of the sliding bottom plate 3 and is placed on the edge of the longitudinal seam welded pipe 5 on the sliding bottom plate 3. Linear movement ensures the stability of induction heating; two side brackets ...

Abstract

The invention proposes a current loading device and a current loading method. The current loading device includes a general bracket, two clamping devices, an induction coil, an upper connecting rod, a temperature vision camera system, a sliding subsystem, a computer processing terminal, a pulse current sub system and longitudinally welded pipe. By using two induction coils to heat the straight seam welded pipe from the side of the weld seam, the temperature vision camera system directly collects the temperature distribution image, and after the computer processing terminal analyzes the collected temperature distribution image, it controls the corresponding electrode control unit in real time. The on-off of the pulse current of the position electrode makes more pulse current flow from the preset temperature zone, realizes the loading of pulse current, and provides a certain basis for exploring the principle of pulse current.

Description

technical field [0001] The invention belongs to the field of heat treatment, and relates to a device and a current loading method for accurately performing current loading. Background technique [0002] Pulse current can improve the properties of metal structures. Patent CN101850475B discloses a current loading method and equipment for current-carrying friction stir welding. A current loading method and equipment for welding by generating resistance heat and friction stirring heat, jointly heating and frictional plastic deformation of workpiece joints. However, it only uses the heat generated when the pulse current is applied to increase the temperature of the entire welding area, but does not accurately apply the pulse current to a specific temperature zone, so it is impossible to study the impact of the pulse current on a single temperature zone. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a precise curren...
