A cold roll forming machine is a machine and equipment used to process sheet metal or metal strip into various cross-sectional shapes through a continuous cold roll forming process. This process does not require heating, and uses continuous rolling and bending operations of the forming rolls to gradually form the metal strip into the desired cross-sectional shape. Cold forming machines are widely used in the manufacture of building materials, automobile parts, shelves, steel structures and other products.
Before applying cold bending profiles for cold bending, it is still necessary to conduct a cold bending test on the material. The intention is to see if there are any defects in the material after bending, and to determine the cold bending diameter and bending angle of the material. Parameters. As a mechanical device used for cold bending operations, the use of cold-formed steel machinery is becoming more and more widespread, and the requirements for it are becoming more and more demanding. In order to equip PLC control in the equipment, the equipment of the control system should be appropriate and can be precise and strict control. In addition, in terms of control accuracy and product production process, it should be able to meet the production requirements and expect the desired effect.
Cold-formed steel machinery for cold-formed steel forming skills with energy-saving, environmentally friendly and efficient advantages, so that it is widely used in construction, bridges, vehicle manufacturing, machinery manufacturing and container production and other professions. However, the use of the role and the nature of the material, the surface quality of the material, as well as the length and thickness of the material is inseparable. Cold-formed steel machinery is used to form cold-formed sections of special equipment. It is designed and customized according to user requirements and belongs to non-standard equipment. Cold-formed steel machine firstly installs the original material on the uncoiler, and then manually feeds it into the host machine, and then through the mold of the host machine and some special auxiliary molding equipment to make it gradually deformed in order to constitute a certain several shapes, and then cuts through the cutting mechanism to be fixed to a certain length in order to achieve the user's intention of applying the product is manually removed from the receiving station. Cold-formed steel machine mechanical, electrical and hydraulic parts must have sufficient rigidity and resistance, accurate and reliable control, sufficient power, simple operation, easy protection and long service life. Cold-formed steel machinery in the roll is an important part of the roll, its design also reflects its uniqueness. Rolls should be subjected to equal stress every time they pass in the cold-formed steel machine so that they can wear evenly, thus extending the utilization life of the rolls.) Ordinary rolls are made of C12MoV material, which is necessary to be handled properly due to its outstanding wear resistance, but attention should be paid to hardness and strength.
The upper and lower rollers or leveling wheels should be protected by effective tubing, otherwise problems may simply occur during operation. For example, the slide will have ambiguous or deformed trajectory, but also will be subject to uneven stress, which will shorten its operating life. In the rolling process of cold-formed steel machinery, it is necessary to consider rolling stability. If the material is deflected from side to side in the raceway, it is necessary for us to take appropriate measures. For example, the gap between the rolls can be kept consistent during the collocation. And before the material bites in, a guide ramp can be set to avoid this problem. In the process of production, if there is zigzag and distortion, the main reason is that the force is not balanced, so it is necessary to balance the force in the design so that it can be processed accurately.
