Bolt fixed on thin-plate and special manufacturing die

At present, bolt head parts or nuts are always welded on a steel plate when bolts need to be fixed on a thin plate, and if materials can not be welded, users have no any methods. In addition, when the steel plate is welded, a welded structure not only has the problems of high dissipation of energy and low efficiency, but also has the defects of easy desquamation, etc. The utility model provides bolts which are fixed on the thin plate without welding and special manufacturing dies thereof. The bolts which are fixed on the thin plate achieve the purpose that the bolts can be effectively and reliably fixed on the thin plate through depending on the bolt head parts which are made into rivets, and the utility model can be used for the malleable thin plate without being subjected to the restriction that whether the materials can be welded or not, and the bolts which are fixed on the thin plate have not the anxiety of the influence on material performance and the desquamation of welding spots. The special manufacturing dies of the bolts, which are fixed on the thin plate, are a press mould of blanks and a press mould for riveting a rivet part and the thin plate in the process of manufacturing the special dies. The utility model has the advantages of simpleness and reliability.
