Riveting machine Rivetless riveting machine are joint two layers of several layers of metal board by punch or by roll press to made it formation into need, and becoming the work piece has the certain anti-pull strength and anti-share strength. Application scope: The rivetless riveting machine suitable for joint the steel plate, stainless plate, zinc and aluminum etc. The rivetless joints can divided punch joint, roll joint. In regard to the method, the roll joint by radial rivetless riveting machine to have many advantages obviously: 1Good quality after process and metal flown line are naturally, the pieces of layers are firm and smooth (can reach the Ral. 25um). 2Labor-saving and economy energy (pressure only 1/10-15 of the punch joint), the weight also lower. 3It's unnecessary to match the boost cylinder equipment, therefore, the equipment's manufacturing cost more lowers 4The national patent technology, the time shows can be adjusted and accurate to 0.1 second. 5Because of the gentle pressure, the molding tool to lower consumedly.
