CNC Angle Steel Punching, Marking & Cutting Machine
This machine is a device that integrates punching, typing and shearing for the angle steel. One machine can finish three functions for three kinds of metal materials.
1. The machine is professional automatic equipment for marking, punching and shearing in iron tower manufacturing industry.
2.CNC automatic production line offers highpunching speed and high stability.
3.The angle bar can be processed into finished angle in one time as passing through the machine.
4.The machining process is numerically controlled and the operation is very convenient.It can achieve automation,high precision,multi-species and mass production.
5. Friendly computer interface is easy to operate.It can accept certain processing program which is made by lofting softrware.And it also supports manual programming.
Apply scope:
This production line is consists of a loading part, a feeding part, the main part of the machine, a finished product unloading part, and the corresponding hydraulic system and electrical control system.
The Loading part:
It is mainly composed of a horizontal transport table and the overturning loading unit.
(1) The horizontal transport table is driven by the sprockets and chain, and realize the synchronization of the three chains with shift blocks. This makes the angle steel stable and low noise in the conveying process.
(2) Reversing and loading unit is driven by the sprockets and chain, and through a long shaft and a self-made coupling to realize the synchronization of three rotating arms with reclaiming claws. The function of this part takes the angle steel to be processed in the trough on the material table to the feeding channel.
The feeding part:
It is mainly composed of feeding channel and CNC trolley unit.
(1) The feeding channel is composed of conveying rollers, brackets, transmission racks, and moving raceways.
(2) The feeding trolley is composed of a moving body, a clamper, a clamping cylinder, a swing cylinder, a servo motor, and an encoder. When working, the feeding trolley is moved by guide rails on the plane and side of the drive rack on the feeding channel with the clamper according the instruction from the computer.
The main part of the machine:
It is composed of pressing angle steel unit, marking unit, punching unit and shearing unit.
(1) The main function of the pressing unit is to press the angle steel to prevent the angle steel from deviating leading to the accuracy error.
(2) The marking unit can realize the exchanging position of four character box. According to the instructions of the computer, mark at the position required by the drawing. By the way manual adjustment mechanism is added, so that easy to change the position of the character's head to adapt to the typing position of different specifications of angle steel.
(3) Punching unit: In every side can be equipped with three different specifications of punches, in each punches is equipped with a air cylinder. In the piston rod of the air cylinder there is a cushion block which is located between the punching rod and the pressing head of the hydraulic cylinder. According to computer instructions, the punch is automatically selected, that means, the corresponding air cylinder is selected to push the corresponding cushion block to realize the selection of the punches;
(4) The shearing unit is composed of a frame-type body, a shearing cylinder, an upper knife
mechanism, and a lower knife mechanism. The lower knife mechanism can adjust the gap according to the thickness of the angle steel to ensure the cutting quality.
The feeding device can prevent the angle steel from hitting the lower blade. Cutting three profiles can be achieved by changing different molds.
Unloading part of the finished products:
It is composed of workpiece support roller and turning cylinder. Through the button control on the button station, the processed workpiece is turned out and placed on the left or right side.
The hydraulic system consists of oil tank, high pressure and low pressure pump group, cooler, main valve group and other control valve groups. It is used to provide working power to each oil cylinder of the machine.
The electrical control system:
It is composed of an electrical operating cabinet, operating box and a trolley operating station.
(1) On the host computer is installed the control software with which inputting the processing parameters onto the computer to finish the programming. The computer also identify the programming fire which is made from CAD OR CAM.
(2) With the PLC of Japan Mitsubishi Corporation as the control core, it is equipped with a three-axis CNC module, which forms a position control loop together with the X, A, and B axis servos, so that the PLC and CNC are integrated, which greatly improves the reliability of the system.
(3) X, A, B axis drive adopts advanced AC brushless servo motor to ensure fast and accurate positioning and maintenance-free.
(4) The control software monitors the operation of the machine at any time. When a fault occurs, the screen will display the detailed cause and treatment method of the fault.
