Intelligent automatic induction heating device

Abstract

The invention discloses an intelligent automatic induction heating device and belongs to the technical field of welding engineering. The intelligent automatic induction heating device comprises a vehicle frame, an induction coil, a control panel, a lifting platform, a lifting mechanism, a workbench and a translation driving mechanism. The lifting platform is arranged above the vehicle frame and connected with the vehicle frame through the lifting mechanism, wherein the lifting mechanism comprises an air cylinder and two parallel rod mechanisms. The workbench moves on two guide rails through four guide wheels. A stepping motor and a speed changing box fixed to the lifting platform are matched with a nut fixed to the bottom of the workbench through a threaded rod. The control panel is electrically connected with the induction coil, the stepping motor and an induction heat source. When the induction heating device works, the movement track of a welding gun is matched with a welding seam in a welding part on a cast iron platform. The induction heating device not only has the automatic walking function but also has the lifting function so that stability and efficiency of induction heating can be improved; and the HHT technology of an induction heating power source is improved and perfected.

Description

technical field [0001] The invention relates to an intelligent automatic induction heating device, which belongs to the technical field of welding engineering. Background technique [0002] The principle of induction heating is that the workpiece is placed in the inductor to generate an alternating magnetic field to generate an induced current of the same frequency in the workpiece. The distribution of this induced current in the workpiece is uneven, strong on the surface, but weak inside, until The core is close to 0. Using this skin effect, the surface of the workpiece can be heated rapidly, and the surface temperature rises to 800-1000°C in a few seconds, while the core temperature rises very little. [0003] Commonly used current frequencies are: [0004] 1 High-frequency heating: 100-500KHZ, commonly used 200-300KHZ, suitable for small and medium-sized parts. [0005] 2 Intermediate frequency heating: The current frequency is 500-10000HZ, and 2500-8000HZ is commonly u...
