Portable magnetic span plate used for steel plate split joint and welding

Abstract

The invention discloses a portable magnetic span plate used for steel plate split joint and welding. The portable magnetic span plate mainly consists of a handle, two permanent magnetic suction discs and a span frame, wherein the span frame is connected with the two permanent magnetic suction discs, two permanent magnets are arranged in the permanent magnetic suction discs, the permanent magnetic discs are provided with a suction disc switch connected with one permanent magnet, the handle is provided with a triggering end matched with the suction disc switch, the fixation between the magnetic span plate and the welding steel plate completely relies on the magnetic force generated by the permanent magnetic suction disc, the matching of other auxiliary equipment is not needed, and the use is flexible and convenient, so the work efficiency of the steel plate split joint in the construction process is improved. Because the welding is not needed, no any mark is left on the surface of parent materials, any influence cannot be generated on the parent materials, any treatment is not needed, the grinding work load in the construction process can be reduced, the production cost and the work intensity are reduced, the operation safety factor is high, any potential safety hazard cannot be caused, and the portable magnetic span plate is applicable to the fixation different parts in different connection forms during butt joint, corner connection and the like of the steel plates in the steel plate split welding.

Description

technical field [0001] The invention relates to a steel structure processing and manufacturing tool, in particular to a horse-board tool for assembling and welding steel plates. Background technique [0002] At present, in the steel structure processing and manufacturing industry, the fixed tooling for assembling and welding between two steel plates is a simple rigid steel plate. Rigid horse boards are generally processed and formed by 10mm~16mm thick steel plates. connect. This tooling mainly has disadvantages such as waste of materials, difficulty in installation and removal, damage to the surface of the base metal, horse foot weld scars on the base metal, and welding holes at the weld, which lead to a large workload of grinding. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a reasonable mechanical structure and permanent magnetic properties, which can not only solve the difficult problem of in...
