The development demand of Z-section steel and the rapid development of Z-section steel industry have intensified the competition among enterprises to a certain extent. The direct consequence of competition is to promote the development of industry and quicken the exit of backward enterprises, which provides convenience for enterprises. Conditions for the reorganization of industry resources. After years of development and competition, many enterprises with considerable strength have realized that competition is inferior to competition and blocking information is inferior to strengthening communication and sharing. Domestic enterprises must join forces to compete on the world stage. Our common competitor is our foreign counterparts. With the decline of the performance of some color steel forming machines, a new round of talent flow has become inevitable in the industry. Our business leaders should clearly see that the brain drain of enterprises is not only the brain drain, but also the loss of core technology, management ability, reputation, market customers and development potential.
One of the development directions of Z steel is to continuously meet various application requirements and realize multi-functional products. Electrical control cabinet columns, profiles and rack materials need to be pre-stamped before forming. Because of the high requirement of hole spacing and geometric shape, large deformation is not allowed in the bending process, so the simulation study and control measures of pre-punching deformation of cold bending machine are very important. Taking pre-punched sheet as an example, a new method for controlling the pass deformation in bending process of bending machine is put forward through field test. The mechanism of the pass deformation is analyzed, and the experimental results are summarized. At the same time, the machining process is simulated by computer simulation software, and compared with the field test results and computer simulation results.
The working principle of Z steel is mainly used in steel bending machine. After the roller reducer drives the contact, it is locked by the handle to start the motor pump set and output the pressure oil through the relief valve through the electric pump. This process can adjust the required pressure. Three-way block electro-hydraulic valves, electro-hydraulic valves and mobile switches control the cylinder, the cylinder propulsion, calculation will start with three steel support roll bending deformation will not occur, and then push the cylinder length every increase of 10 mm-15 mm, open. The main motor works forward or backward, and the main motor drives the steel parts to work repeatedly to meet the required date.
In recent years, China has been focusing on the development of environmentally friendly equipment, and environmental awareness will become an important mainstream in China in a few years. In the development of environmental protection equipment, cold bending forming equipment will undoubtedly become the mainstream of the market, but also lead to the development of cold bending forming steel equipment, the key is the development needs of application courses, using various products to achieve. Certain functions. The first thing to be eliminated is to cooperate with punching. Therefore, with the vigorous development of the whole environmental protection market, cold bending forming equipment will become more and more important. For the cold rolling forming device, the common forming methods include stamping, forging, extrusion and welding equipment which can be formed.
