The automatic production line of angle steel is mainly used for iron tower production in power transmission and transformation industry and metal structure factory. According to the parameters entered in advance, it can automatically complete marking, punching and fixed length cutting (the same function as cut to length machine)on the two right angle sides of angle steel.
The CNC angle steel production line has the functions of marking, punching and cutting angle steel. The punching unit of the production line adopts a closed body, which is more stable and safe. Two punching units can punch two sides of the angle steel respectively. Each punching unit contains three punching die positions. Angle steel can process three different apertures through the punching unit, and the punching unit uses hydraulic pressure as punching tool The maximum punching force can reach 1000KN.
The Angel steel cutting machine of the production line also adopts the closed structure. In order to ensure the processing effect, the double-edged cutting method is adopted at present, and the maximum shear force can reach 1540kn.
The angel steel marking machine of the production line can be equipped with four different characters at one time for automatic processing in the production process.
The punching force is 1200kN, and the printing effect can ensure that the angle steel can still be clearly visible after painting or galvanizing.
1.Specificity: Angle Steel Punching Shearing Marking Line has the characteristics of mass production.
Worked as angel steel punching machine it is suitable for punching different hole diameters on angle steels of different specifications, and three kinds of punches of different specifications can be placed on the same punching unit.
Integration of machinery, electricity and hydraulic.
Worked as Angle Steel Shearing machine,it can cut the steel to certain length.
Worked as Angle Steel marking machine,it can mark characters to the steel.
All these machine combined together to work as a angel steel processing line.
3.Computer control and high degree of automation, and the precision of parts reaches the relevant standard of GB2694-81 “technical conditions for manufacturing transmission line tower”.
Angel Steel Feeding, Angel Steel marking, Angel Steel punching, Angel Steel cutting, sorting and stacking are all automatic, with good precision and high production efficiency.
The computer is used to optimize the layout, and the material utilization rate is high.
The punch is easy to replace.
The communication between the upper computer (commercial computer) and the lower computer (programmable logic controller) is reliable, and the programming is simple.
CNC Angle Steel Punching Shearing Marking Line Machine application
The automatic CNC Angle Steel Punching Shearing Marking Line Machine
is a kind of production line for power tower, which can be used in the hole punching of angle steel of electricity transformation tower and the production of components in metal structure factory.
The production line is composed of angel steel transverse feeding table, overturning feeding unit, feeding channel, numerical control car, angel steel marking unit, angel steel punching unit, angel steel shearing unit, sorting channel, equipped with hydraulic system, pneumatic system, electrical control system, etc
The following is an explanation of each component.
1. Marking carriage
It is used to support the marking unit body, on which two guide rails can be used for the body to slide. A typing cylinder is installed to push and pull the machine body to select the typing position or feeding position.
2. Marking Body Unit
The Marking utility model is provided with a typing structure, which can be divided into open type and closed type. It is equipped with a four bit word box selection cylinder and a word box disk, and has four module positions for selection.
3. Punching and pressing Unit
The connecting rod swing pressing structure is adopted, which has large pressing force and can firmly locate the angel steel.
4. Punching master cylinder
The ange steel punching master cylinder is installed on the side plate of the fuselage, and a punch pressure head is installed on the piston of the cylinder to drive the punch rod to move. The punch rod can slide on the punching die base, and a female die is arranged under the die base.
5. Shearing fuselage
The shearing cylinder is installed on the upper plane of the inner frame of the fuselage, and the cutting part is installed on the lower plane of the inner frame of the fuselage.
With powerful shearing and cutting powered by the angel steel shearing and cutting machine,the Angle Steel Punching Shearing Marking Line is good to process angel steel.
6. Tool loading mechanism
The upper blade mounted on the upper blade and the lower blade mounted on the lower blade cut off the workpiece under the action of the oil cylinder.
7. Die position selection device
The die position selection device is installed on the punch head, which is composed of cylinder, pad block and pneumatic valve group, and the cushion block is pushed out or pulled back by the cylinder. When the pad is pushed over the punch bar, the press head presses the punch rod to complete the punch hole; when the pad is pulled back to the back position, the punch rod is empty, and the die position cannot punch.
8. Servo feed device
The servo feed device is used to control the feed of angle steel in the direction of alignment. It is mainly composed of sliding plate, precision ball screw and servo motor.
- The angle steel production line is equipped with upper computer, and special workpiece programming and system control software are installed to complete angle steel workpiece programming, machine operation monitoring, fault inspection, etc.
- Taking PLC as the control core, the three-axis CNC module is configured to form the position control loop together with X, a and b-axis servo, which makes PLC and NC integrated and greatly improves the reliability and flexibility of the system.
3, X, A and B axis drive uses AC brushless servo motor to ensure fast and accurate positioning and maintenance free. The positioning speed of a-axis and b-axis is 10m / min, and the no-load positioning accuracy is ± 0.02mm. The positioning speed of x-axis is 50M / min, and the no-load positioning accuracy is ± 0.2mm.
- The programming software has many functions and is easy to learn. It can be programmed and arranged. The workpiece graph can be displayed on the screen in real time and the program can be checked.
- The angle steel line control system can directly convert the angle steel line workpiece program generated by lofting software. In this way, the user can omit the programming process of the workpiece program, and directly copy the workpiece program generated by the lofting software to the upper computer of the angle steel line with floppy disk or through the network.
- The control software monitors the operation of the machine at any time. When there is a fault, the screen will display the detailed fault causes and treatment methods, which greatly saves the maintenance downtime.
- Both the front and back ends of the angle steel line have the function of cutting free processing (that is, both the front and back ends are set to 0 mm, and the system will no longer issue cutting instructions, which is suitable for the customized fixed length angle steel processing).
