The model of the controller PLC2 is XD 3-48R-E.

The working principle of the punching part is as follows: when a knob SA12 on an electric control operating platform of the punching part is opened, Y1 of the PLC2 outputs signals, KA21 works, KM1 is electrified to be attracted, and a hydraulic pump runs. The automatic knob SA11 is turned on, Y3 of the PLC2 outputs an automatic operation signal of the leveler, the frequency converter VF4 drives the leveler to operate at a high speed in a forward direction, the leveler drags the coiled plate on the discharging rack to move forward, meanwhile, the rotary encoder for measuring length is driven by the plate to rotate and send out pulse signals with a phase difference of 90 degrees, and the PLC2 calculates the forward size of the plate according to the pulses and displays the forward size on the touch screen. When the display size in the PLC2 approaches the punch size set by the operator, the Y5 of the PLC sends a deceleration signal to decelerate the leveler to prevent the machine from operating too fast and overshooting the size under inertia. The leveler stops until the PLC2 size equals the operator's set punch size. At this time, the PLC executes a punching operation (the operation of the a die or the operation of the B die may be selected on the touch panel according to the operation set by the operator). After the punching action is completed, the leveling machine is automatically lifted to the upper limit position of the die, and the PLC2 continuously sends out an operation command (the principle is the same as the above), so that the leveling machine is operated in the forward direction.

When the size of the PLC2 is close to the total length of the workpiece set by the operator, the leveler is decelerated in advance until the size of the PLC2 is equal to the total length of the workpiece set by the operator, and the leveler stops operating. At this time, the shearing die acts to shear the plate into a single plate. At the same time the PLC2 is sized to clear all previous sizes in preparation for the next run. After the shear die is raised to the upper limit, the PLC2 continues to move the leveler forward for the next cycle.

All the above operation processes are automatically controlled and completed by the PLC 2. When the automatic knob SA11 is closed, the lifting action of any mold can be executed through the touch screen and the knob on the operating platform, or the forward rotation or reverse rotation operation of the leveler can be executed, so that the equipment can be conveniently debugged.

The working principle of the conveying part is as follows: the cut veneer enters a conveying table, a knob SA2 on an operation table of the forming machine is turned on, Y0 of a PLC1 outputs signals, KA1 acts, KM4 is electrified to be attracted, a conveying roller operates, and the plate continues to advance. When the plate advances to a photoelectric switch SQ5 at the positioning position, a signal is output by Y3 of the PLC1, the relay KA4 is attracted, and the positioning cylinder drives the positioning roller to enable the plate to be close to the fixed side and to be aligned with the roller of the forming machine so as to prepare for entering the forming machine. And the plate continues to advance, when the plate reaches a photoelectric switch SQ4 at the feeding position of the forming machine, a signal is output by Y1 of the PLC1, the relay KA2 attracts, the material pressing cylinder performs downward pressing action, the movable roller is pressed with the fixed roller below, and the plate is clamped and conveyed into the forming machine. After the action is completed, all signals and the air cylinder are reset, and preparation is made for the next action.

The working principle of the forming part is as follows: before the forming machine automatically operates, an operator needs to adjust the width of the section to be produced. Inputting the plate width needing to be fed and the bottom width of the formed section on a touch screen, and then clicking to automatically adjust. The PLC1 outputs corresponding forward or reverse rotation signals according to the width input by the operator, and the frequency converter VF5 works to enable the width adjusting motor to operate to drive the forming machine set to move transversely. For example: the current feeding width is 600.0mm, and operating personnel input feeding width is 800.0mm, and the target width is greater than present width of showing then transfers wide motor corotation, and the feeding plate width of anterior segment is surveyed wide photoelectric signal SQ2 and is sent into PLC 1. When the current feeding width displayed on the touch screen is equal to 800.0mm, the PLC1 stops the operation signal of the width adjusting motor, and the feeding width adjustment is completed. Otherwise, the width adjusting motor rotates reversely until the width adjusting action is completed.

The adjustment of the rear section forming bottom width is the same as that of the front section feeding plate width, and the two groups of width adjustment control two motors to respectively operate by using two groups of different width measurement signals (a front section feeding plate width signal SQ2 and a rear section forming bottom width SQ 1). However, the two motors are controlled by the same frequency converter VF5 and are switched by contactors KM2 and KM 3. When the operator adjusts the width of the front section feeding plate, the KM3 automatically attracts, and when the operator adjusts the width of the rear section forming bottom, the KM2 automatically attracts. One frequency converter is used for freely switching and controlling two width adjusting motors, so that the cost is saved for users.

When the whole production line is in on-line production, the forming machine can start or stop along with the leveling machine, so that each sheet material sequentially passes through the leveling punching machine, the conveying table and the forming machine until reaching the material receiving table. Therefore, the rolled plates can be uncoiled, leveled, punched, conveyed, formed and finished products can be collected in a large batch. The front section and the rear section of the cold-bending forming part are respectively controlled by a frequency converter VF1 and a frequency converter VF2, and the speeds of the front section and the rear section can be respectively and independently adjusted, so that the forming speed is matched before and after, and more ideal section bars are produced.

When a small amount of customized sectional materials need to be produced, the leveler (VF 4), the hydraulic punching part (SA 12) and the like are closed, one or two single plates cut in advance are placed on the conveying table, and the single plates can be positioned, conveyed and formed by only starting the conveying rollers (SA 2) and the forming machines (VF 1 and VF 2) until the material receiving part.

When special profiles which cannot be finished by the forming part, such as excessively wide or narrow bridge profiles, need to be produced, the forming part (VF 1, VF 2) is closed, and only the leveling (VF 4) punching and shearing (SA 12) part needs to be started. Therefore, coiled materials meeting the width requirement can be uncoiled, leveled, punched and sheared, and then conveyed to a conveying platform, and finally can be manually conveyed to a hydraulic cold bending machine to finish final bending forming, so that the section which cannot be finished by a cold bending forming machine is produced.

When the bridge cover plate needs to be produced, the forming bottom width is adjusted to the maximum width by the rear-section forming bottom width adjusting parts (VF 5, KM 2), and then the rear-section forming machine (VF 5) is closed.

If the punching function and the forming part are completely closed and only the leveling and shearing functions are kept, the production line is equivalent to a decoiler.
