Cold roll forming machine is widely used in many fields, not only increase the output, but also greatly improve the quality of the products, so both of the design and manufacture of cold roll forming machines are very important.
Firstly, design and manufacture of roll form machines according to the average stress for different principles, all of the rollers stress averagely, with the balance of the wear and prolong the service life of cold roll forming machine.
Secondly, usually roll forming machines manufacturers adopt C12MoV material with wear-resisting performance, but its specific strength and hardness is contradictory, when doing heart treatment, it must use the red hardness of C12MoV material, through twice or even three times tempering can be reached to the hardness after quenching.
Thirdly, orbit arc part of this kind of forming machine is the core position of sliding rail, the circular arc position after the first few moulded, in the back pass rolling vertical edge to deal with the established arc, through the roll up and down to do effectively control protection, otherwise, the circular arc part will be changed in the process of drawing of the materials. When R has shrunk as triangles, because of the steel ball cannot be in the end which makes the two contraction produce noise. When R becomes bigger, shaking with rail, the usage of slide rail track makes it fuzzy, uneven, slide rail deformation and shorten its life of the cold roll forming machine.
Fourthly, it ...
