② Maximum outer diameter of coil: 1200mm;
③ The expansion and contraction range of the unwinding head is Φ 470 ~ Φ515mm;
④ Maximum width of the roll: 1020mm;
⑤ Maximum load of single head: 3mt.
2. NO-Pit-Guided Device
2.1 Device Composition
a. The material guide method is inclined plate, and the guide ramp uses
stainless steel smooth bean plate or plastic insulation plate to reduce friction damage to silicon steel sheets.
b. The material guide ramp is equipped with multiple inductive sensors to
realize intelligent flexible buffer acceleration and deceleration of material discharge. The material is pressed by a rubber plate to ensure that the material is transported without jumping.
c. Equipped with symmetrical adjustable material stop rod.
d. This device can automatically guide materials into the equipment in
conjunction with the feeder without manual intervention.
3.Feeder
3.1 Device Composition
The mechanism consists of a feeding part, a length measuring part and an auxiliary traction part.
3.2 Device Functions
The feeding part is driven by a servo motor to ensure stable and reliable feeding. The measuring wheel of the length measuring part is connected to a high-resolution encoder to fully ensure the feeding accuracy. The track guide bearings before and after the feeder are made of ceramic bearings, which have good durability (no obvious wear) and effectively ensure the feeding accuracy.
The auxiliary traction is set before the shearing machine. The participation of this component ensures the straightness of the sheet before shearing.
4. Punching Section
4.1 Punching Machine
The equipment is equipped with 3 punching machines, which use servo
motors to control the shearing action. The punching machine is controlled by a servo motor and can move horizontally (perpendicular to the track) to achieve the function of punching and shearing eccentric holes in silicon steel sheets ( D-shaped holes).
Punching lateral movement range: ±150
4.2 V notch
The equipment is equipped with 2 V notch machine, which is relatively staggered and precisely controlled by servo motors to meet the needs of single shearing yokes. The V notch are fixed longitudinally and can move horizontally to meet the requirements of step-by-step shearing.
V-notch lateral displacement: ±50mm.
5. Shearing Machine Section
Oblique shearing machines, driven by servo motors, each with 1 set of cutters, of which shear #1 can adjust the angle, that is, it can be fixed at a working position of 45 ° or 90° , fixed longitudinally and can be servo- driven to shift laterally.
6.Tension Pulling Mechanism
The equipment is equipped with a tension pulling mechanism, with two sets of wheels at the top and bottom , which keep the material in a straightened state during the punching and shearing process; the lower roller is precisely controlled by a servo motor to form a closed-loop operation with the main feeder.
The function of this mechanism is to improve shearing accuracy and shearing speed.
7.Discharge Guide Mechanism
The flat belt conveyor of this mechanism is supplemented by rail guides on both sides, and is equipped with a pressure wheel and a detection device. This mechanism makes it easy to keep the sheared sheet in a center alignment state before entering the material dividing inclined belt.
8. Material sorting mechanism
8.1 Device Composition
The system consists of a material distribution mechanism, an inclined belt conveyor, a photoelectric detection system, a flat belt reverse suction
conveyor, etc.
8.2 Device Functions
The oblique belt conveyor adopts magnetic suction for stable conveying. The function of the flat belt reverse suction conveyor is to make the sheets stacked flat on the material table to achieve flexible and lossless stacking. Two sets of photoelectric detection devices are installed to achieve accurate positioning of the stacking materials.
9. Stacking Mechanism
9.1 Device Composition
The discharging system includes a material stacking table
and a hydraulic lifting electric roller unloading car.
9.2 Device Function
The stacking mechanism is divided into two sets on the left and right, each set can be moved laterally independently, and each set has one station on the top and one station on the bottom, which can realize 2 for use and 2 for backup;
The upper workstation of the stacking mechanism is equipped with a hydraulic system which can be turned over to facilitate lifting to the lower workstation.
10.Waste centralized collection and transportation mechanism
This type of waste collection and unloading machine is suitable for shearing scraps, offcuts, etc.
This is independently controlled, with a maximum load of 1000kg, and is transported to the waste box through the conveyor mechanism. The ground conveyor mechanism can be controlled, and the conveyor mechanism will sleep when there is no waste.
The mechanism is equipped with a complete electric conveyor belt and waste box to automatically transport various wastes to the waste box.
11.Center positioning automatic linkage width adjustment mechanism
The width adjustment mechanism adopts linear guide rails, precision ball screw transmission, and servo motor control width adjustment to fully ensure the width adjustment accuracy. The width adjustment of the entire line is linked, electric centralized width adjustment, and encoders are used to achieve data feedback.
