Roll Forming Machine Working Principle and Common Problem Analysis

　　 Roll Forming Machine Working Principle and Common Problem Analysis

Roll forming machine is used in the industrial production of metal cold bending forming equipment, can meet the requirements of industrial production to a specific shape, cold bending forming machine got as it comes to the good market development, currently on the market many varieties, for some hot rolling method to produce uniform wall thickness, section shape of complex various materials and various material of cold bending steel can easily cope with it.

 　　 Cold - bending machine production of finished products with high finish, beautiful appearance, precise size. The steel produced by cold bending forming machine belongs to the economical section high efficiency steel, saves the cost, the cold bending forming machine is widely used to replace the hot rolled profile and other varieties.

 　　 Composition of cold forming machine:

 　　 Cold bending machine is mainly composed of base, mechanical transmission, cold bending operating system, hydraulic working system and other parts.

 　　 Working principle of cold forming machine:

 　　 When the cold bending forming machine is working, put the steel plate and other metal materials that need to be processed by the cold bending technology between the two driving wheels, start the hydraulic system, make the hydraulic cylinder push the dovtail groove and the cold bending wheel cold pressing section steel, close the hydraulic system when the curve required by the design is reached, and then start.

 　　 Repair and maintenance of cold forming machine:

         In daily use must be in accordance with the operation regulations to operate, regularly for the mechanical equipment oil lubrication, and to ensure the cleanliness of the cold bending machine. Secondly, it is necessary to check the machine itself regularly whether there are parts with serious wear, if there must be timely replacement, in order to avoid unnecessary failure and unnecessary loss in use, and to the chain and other components often add lubricating oil, roller with butter, roller if not used for a long time should add diesel to clean. Finally, the slide side of the cold bending machine is often daubed with anti-rust oil to prevent the rust of the equipment, especially in the case of the equipment is not used for a long time, it should be carried out this operation, in the case of no oil in the oil tank must not start the generator, to prevent damage to the machinery itself.

 　　 Analysis of common problems of cold forming machine:

 　　 1. Due to the left and right force imbalance, or the upper and lower force imbalance, often cause bending and distortion problem, can design its force balance to solve, installation adjustment, accurate processing.
 　　 2. Due to the force asymmetry of a single set of rollers, left-right deviation of materials in the raceway is often caused. To solve such problems, the first thing is to calculate the neutral layer accurately in the deformation zone, calculate the material accurately in the deformation zone, and process the rollers with good symmetry. Secondly, the non-deformation area shall be as far as possible free from compression (such as the bottom of the slide rail), and the clearance of each area of the upper and lower roller shall be consistent during assembly.  Finally, the guide ramp should be set up according to the rolling state of the front track before the material is bit in. Before stabilizing the compression, the material will slide and stabilize in the rolling.
 　　 3. The cold bending machine needs to be placed on a stable table to work more safely and accurately.
 　　 4. Careful inspection should be done before use to make the work safer, smoother and more efficient.
