CAD is adopted

For key components such as body frame, slide block, etc., analysis is carried out by using ANSYS finite element analysis software, to ensure rationality of strength and structure of the body frame.

Overall welding structure is adopted for the body frame, and the machine tool is of good rigidity.

Q235-B material is used for four main components including wall panel, work bench, vertical panel and slide block

Cotrust NC Control System

TP 07 Controll

• 7.0 inch touch screen
• True color LCD-TFT
• Resolution 800x480, 256k colors
• 2 RS485 ports

Integrated welding machine structure

At the time of welding of large components, double “X” groove and automatic submerged arc welding are adopted. During welding, both sides of components are alternately welded to avoid welding deformation. At the weld joints, there is no welding defect such as undercut, pore, crack, etc.. After welding, the components will be detected for any defect.

High temperature annealing aging treatment technology is adopted for machining of the large components, to eliminate welding stress and to ensure accuracy and stabilization of the machined components.

Method of once clamping machining with large floor type boring-milling machine and flexible gantry machining center is adopted for machining of the body frames, to ensure accuracy of machining of the components.

Slider synchronization control

The Y1~Y2 axes are the independent motion parameters of the two oil cylinders controlled by the CNC system. The oil cylinders at both ends of the machine tool are equipped with independent oil supply systems, which are composed of two-way oil pumps driven by servo motors. 

The machine's anti-eccentric load capacity

The pump control system of this machine is a position control system, which dynamically detects the synchronization error of the slider through the grating ruler, and corrects the synchronization error of the slider by the servo motor signal given by the numerical control system, so that the slider is completely eccentric. It can always be kept parallel to the workbench in the case of eccentric load, so it can work under partial load

Fast Clamping

The SMS clamp allows you to reuse the existing intermediate on the bending machine, replacing only the front bracket, thus obtaining, with a minimum investment, a quick change system.

• Manual clamping unit for upper tool withrgonomic lever
• It allows you to reuse the existing intermediate on the bending machine, replacing only the front bracket, thus obtaining, with a minimum investment, a quick change system
• Possibility of fitting tools on the rear side of the clamping units by bracket

Hydraulic System

The German Rexroth fully closed-loop electro-hydraulic servo high-frequency synchronous control system is adopted to ensure that the machine tool has high stability and high precision in the process of high-speed operation.

• The hydraulic system has the function of overload and excess flow protection, making it safe and reliable.
• The oil pump is high-pressure internal gear pump from Japan NACHI Company, which can bear high pressure and produces low noise
• The sealing ring is the product of Germany MERKEL Company, and it has good sealing property, functions well and has long life of service. 
• The hydraulic system has two classes of filtration functions, course filtration and fine filtration, with high filtration precision.

SMS Electric Crowning
