Cold forming machine equipment is a kind of machinery and equipment used to process metal plates (such as steel plates, aluminum plates, stainless steel, etc.) into various complex cross-sectional profiles through continuous bending process.
These profiles are widely used in construction, automotive, home appliances, transportation, energy and other industries. Commonly roll forming machine including Roof Tile Roll Forming Machine, Wall Panel Roll Forming Machine, Ceiling T Bar Roll Forming Machine, Stud And Track Roll Forming Machine, Light Gauge Steel Frame Machine And Cable Tray Roll Forming Machine.
The design principle of cold roll forming:
1. Cold bending equipment gradually bends the material to the desired shape through multiple forming rolls. This progressive molding reduces material stress concentration and prevents cracking or uneven deformation. The shape of the rolls directly determines the cross-sectional shape of the final profile. The curvature and angle of each roll need to be calculated accurately during design, and the layout of each roll should be arranged reasonably in order to realize the best molding effect
2. In order to ensure the precision of molding, the feeding system needs to be highly synchronized with the molding system, usually using servo motors to control the feeding speed and precision. The automated control system can monitor the operating status of the equipment in real time, such as speed, pressure, temperature, etc., and automatically adjust the process parameters according to the monitoring data to ensure product quality and production efficiency.
3. Cold bending equipment is usually modular design, you can replace or adjust the module to produce different profiles, but also to facilitate the maintenance and upgrading of equipment. Equipment design should take into account the convenience of maintenance, the design structure should be as simple and clear as possible to facilitate the operator to carry out routine maintenance and troubleshooting.
Design and manufacturing characteristics
1. track arc part is the core part of the slide, the first few pressure molding after the arc bit, in the second after the channel rolling folded standing edge, should have been molded arc, through the upper and lower rolls or cross wheels, for the protection of the effective tube bundle, otherwise, the material in the process of stretching the arc bit will certainly change, R become small to become a triangle, the steel ball does not go to the bottom, the two points of contact with the resulting cacophony, R becomes large with the track with the wobbling, the slide track when using trajectory Fuzzy, uneven force, slide deformation, shorten life.
The principle of average force on each pass, the whole line of rollers average force, wear and tear equalization, to extend the service life of the rollers.
3. Rolling stability issues, the production of materials often encountered in the raceway in the left and right swing problem, in fact, a single group of rollers subject to asymmetry, the left force is large, the material to the right side of the swing; the right side of the force is large, the material to the left side of the swing.
Roller using C12MoV material is the use of its wear-resistant properties, but the specific strength and hardness is contradictory, heat treatment to take advantage of the red hardness of C12MoV, quenching, two or even three tempering to achieve hardness.
