¡¡¡¡Cold bending is through the sequential configuration of the multi-pass molding roll, the coil, strip and other metal plate continuously to the lateral bending to produce a specific section of the plastic profile processing technology.
¡¡¡¡Cold forming is a new material, energy saving, and efficient metal sheet forming process, new technology. The use of this process, not only can produce high-quality steel products, but also to shorten the product development cycle, improve production efficiency, thereby enhancing the market competitiveness of enterprises.
¡¡¡¡In recent years, cold-formed steel products as an important structural parts in the construction, automobile manufacturing, shipbuilding, electronics and machinery manufacturing and many other areas have been widely used. Its products from the ordinary rails, doors and windows and other structural parts for some special purpose and manufacture of special profiles, the type is extremely wide. Cold section steel unit weight section performance is better than hot-rolled steel products, and has a high surface finish and dimensional accuracy, so cold-rolled steel instead of hot-rolled steel can be achieved both save steel and save energy dual effect, so people on the cold The development of curved steel has given high priority. It is the user of the cold-formed steel products, specifications, quality and other aspects of the continuous desire to promote the rapid development of cold-formed process technology.

¡¡¡¡There are many problems in the rotary drive of the traditional cold-formed equipment: the axial compression of the screw, the limitation of the stiffness and the length, the existence of the periodic error between the mechanical wear, the twist and the pitch, the vibration decay time is longer, Coupling inertia, etc., these problems to a certain extent, limit the cold forming equipment processing speed, accuracy and efficiency. The use of linear motor drive, omit the motor to the table between the intermediate transmission link, in the cold forming equipment processing, the length of the transmission chain is zero, this "direct drive" structure to avoid the traditional rotary drive screw Transmission coupling inertia, mechanical wear and rigidity and other disadvantages, making the cold-formed molding equipment processing performance indicators.
¡¡¡¡The linear motor drive eliminates the need for more space in the middle of the drive section, reducing the reasonable arrangement in the design of the cold forming equipment, reducing the support of the lead wire, and other spaces.
¡¡¡¡Linear motor electromagnetic transmission method can greatly improve the dynamic response of the drive performance, electromagnetic induction of electrical components than the traditional drive mechanical drive higher, the traditional drive device to screw the way not only increased the mechanical reaction time, But also affect the overall response time of the system.
¡¡¡¡The linear motor-driven design eliminates the mechanical transmission components, mechanical zero contact, thus reducing the mechanical wear, low noise, while reducing the mechanical friction in the energy loss, not only to improve the cold bending equipment, environmental performance side, but also Greatly improving the overall system operating efficiency.
¡¡¡¡The length of the stroke in the rotary drive has always been limited by the length of the screw and can not be operated efficiently in the cold forming equipment. The drive stroke in the linear motor depends on the length of the primary laying. The length of the primary laying determines the length of the stroke.
¡¡¡¡Kunshan Tongmao Electronics Co., Ltd. ( is a professional supplier of linear motors. The company's high intelligent linear motors are widely used in all kinds of machinery manufacturing and processing fields. In order to make customers more direct and convenient to use Linear motor, I also introduced a variety of models of linear motor module, follow-up we will continue to focus on R & D and manufacturing more to adapt to the market, suitable for customer demand for linear motor module, welcome friends a lot of attention with the Tongmao Linear Motor.
