One of the most important components of the rolling machine, its quality and performance has a direct impact on the service life of the rolling machine and the precision of rolling.
Working rolls are made of high-strength high-quality steel 42CrMo material, after forging, roughing, quenching and tempering, HB240 ~ 300, finishing after the intermediate frequency quenching HRC47-58, according to JB/ZG4289-86 roll steel standards, the stiffness is consistent (1/700 ~1/1000) L. The distance between the centerlines of the sides rack. And strictly in accordance with the working process of manufacturing all the standard roll manufacturing, to ensure its comprehensive mechanical properties.
According to the movement method of the working roll (side roller) of the rolling machine, the linear slide technology is adopted. The oil cylinder adopts an inverted oil cylinder, which greatly increases the contact area between the slider and the slide rail, and improves the stability and the rolling precision of the machine tool.
The base and frame are the main parts of the equipment. Our company selects high-quality steel, uses CNC cutting, grinding and welding, and then sends the welded structural parts to the professional heat treatment factory for stress relief annealing—CNC lathe machining, eliminating welding stress, so that it has enough strength and stiffness, to ensure normal operation at full load. All records of the workpiece are included in the quality tracking system.
Each oil circuit is routed with two relief valve to control pressures. The maximum set pressure for each oil circuit is 25 MPa, which is mainly to control the main cylinder pressure, and the other relief valve is set to 16 MPa, mainly to control the overturning cylinder and balancing cylinder pressure.
In order to ensure the synchronization accuracy of the main oil cylinders at both ends of each moving working roll, high-precision displacement sensors are installed on the left and right racks and the tilting frames. Through the pressure sensors, the microcomputer control system detects and adjusts the movements of the main oil cylinder pistons to achieve the precison of the both working roll ends.

CNC plate rolling machine loading and unloading is for plate rolling machine processing , which can realize automatic loading and unloading with the robot processing system. It can realize automatic loading and unloading, processing and other tasks during processing, helping the machining industry to improve production efficiency, production quality, reduce costs, and thus improve the competitiveness of enterprises in the industry.
The automatic loading and unloading system of CNC plate rolling machine is mainly composed of two parts: manipulator and programmable control system. The manipulator is used to realize the grabbing, loading and unloading movement of materials, the programmable control system is used to control the movement, positioning and material grabbing and placement of the manipulator.
According to different workpieces, corresponding grippers are designed. For workpieces that need to be reversing, the grippers are equipped with a rotary cylinder for reversing. The end of the Z axis is equipped with a pneumatic quick-change gripper to facilitate the replacement of different workpieces. The dual Z axis is configured to firstly meet the needs of large-sized and heavy workpieces for 1-to-1 pick-up and 1-to-place; secondly, two grippers can also be installed to meet the needs of simultaneous automatic loading and unloading of two workpieces.
The automatic material table is mainly used as a turnover table for manipulators to pick up and place materials. Conventionally, the rough workpieces are placed on the material table at one time by manual labor. The manipulator can grab and load the materials in an orderly manner, and also place the finished workpieces on the material table. When the material table is short of material or full of material, an alarm is issued, manual material replacement is performed again. This process can also be replaced by AGV trolleys or other manipulators in automated workshops to automatically replace manual labor. Different automatic material tables need to be made according to different workpieces and storage requirements.
