Electrical Cabinets Industry Introduction
Electrical cabinets are primarily used for installing and protecting various electrical equipment, including circuit breakers, contactors, relays, variable frequency drives, PLCs, as well as equipment for power distribution, control, and monitoring. Depending on their purpose and installation environment, electrical cabinets can be categorized into different types such as control cabinets, distribution cabinets, instrument cabinets, and cable distribution cabinets.
Typically constructed from metal materials, such as approximately 2mm thick steel or stainless steel, electrical cabinets ensure structural strength and protective performance.
In some special cases, fire-resistant and corrosion-resistant materials may be used. The materials used in the production of electrical cabinets are generally divided into hot-rolled steel and cold-rolled steel. Cold-rolled steel, compared to hot-rolled steel, is softer in texture and more suitable for the fabrication of electrical cabinets.
Electrical cabinets are widely used in various industries including the chemical industry, environmental protection industry, power systems, metallurgical systems, industrial applications, nuclear power industry, fire safety monitoring, and the transportation industry.

The advantages of open screen web cutting machines include:
● Efficient production: The open-screen coil cutting machine can quickly and accurately cut coil materials to improve production efficiency.
● Automated operation: This kind of cutting machine usually has an automated control system, which can reduce manual operations and improve the automation of the production line.
● Precise cutting: The open-screen coil cutting machine can achieve high-precision cutting, ensuring the accuracy and consistency of cutting dimensions.
● Versatility: Some open-screen roll cutting machines have multiple cutting functions to meet cutting needs of different shapes and sizes.
● Save materials: Through precise cutting, material waste can be minimized and costs can be saved.
● Safety: Modern open-screen coil cutting machines usually have safety protection devices to ensure the safety of operators.
The standard laser cutting machine model 3015/3015H is popular in the automotive parts industry for several reasons:
Site and Environmental Requirements
Power supply specifications: three-phase five-wire system, 380V 50Hz;
● Power quality: three-phase unbalance <2.5%, line voltage fluctuation <5%.
Grounding protection: Ground the machine tool, drive a ground pile grounding wire on the side of the machine tool, or connect the machine tool to the ground wire of the power supply. The grounding resistance is required to be <4Ω.
● A site environment with good ventilation, no dust, no corrosion and no pollution is required.
● The installation foundation requires that there should be no major vibration in the surrounding area.
● The chiller is used to cool special equipment such as lasers, cutting heads, and QBH. The cooling circulating water requires the use of high-quality pure water or distilled water;
● To prevent the occurrence of fire, the processing site should be equipped with appropriate fire extinguishers and reserve certain fire extinguishing channels.

Structure of uncoiling fiber laser cutting machine
The uncoiling and blanking cutting production line developed by our company provides an integrated solution of coil unwinding, correction, follow-up cutting and blanking. The complete system consists of a coil loading trolley, a single-arm decoiler, hydraulic auxiliary support, a feeding device, a leveling machine, a guide device, a rolling cutting platform, a laser cutting system, a material receiving platform, a hydraulic and pneumatic system, and an electrical control system.
It replaces the traditional working mode of flattening the coil and then shearing it, then transporting it to the laser cutting station, and then cutting and manually cutting the material.
It improves material utilization, reduces labor costs, which is suitable for large-volume, multi-graphic processing, and reduces punch mold and other costs, effectively improving production efficiency.
(1)Coil loading trolley:
The coil loading trolley is designed to move the material to the main shaft expansion and contraction structure of the decoiler. It is used to hold up the material during decoiler, so that the material belt can smoothly enter the leveling machine. The trolley is equipped with a mechanism to prevent the material roll from tipping and to move narrower rolls
| Material seat shape | The load-bearing surface is a V-shaped structure |
|---|---|
| Trolley walking drive mode | Cycloid motor |
| Trolley lifting drive method | Hydraulic cylinder |
| The way the trolley prevents walking offside | Hard limit |
| Maximum load | 15ton |
| Control method | Manual button control |
| Alignment method | Visual alignment, scale attached as reference |
(2)Single-arm uncoiler
After moving the roll material by the coil loading trolley, the inner diameter of the material roll is fixed at the expansion and contraction position, and the material is rotated intermittently as required to discharge the material.
The thickness of the front and rear main boards is 30mm, and it is equipped with a hydraulic rotating cylinder with a diameter of 150*100, and the system is equipped with a timed pressure compensation system.
Even it is used for a long time, there’s no need to worry about the problem of loose internal roll caused by pressure relief. It could regarded as the second layer of safety wall based on the strong machine.
| Loading roll width | 200-1500mm |
| Load capacity | 12 ton |
| Expansion method | Hydraulic wedge structure |
| Expansion range | 480-520 |
| Spindle drive method | AC variable frequency motor |
| Spindle transmission mode | Double row large spacing chain drive |
| Braking method | Pneumatic butterfly brake |
| Unwinding flow | Lower unwinding method |
| Press arm drive | Pneumatic drive |
| Material arc control | Photoelectric switch control |
(3)Screen-opening and sizing machine
The material is leveled and fed (the entire roll of material will not deviate after being fed), and the mechanism for making fixed-length feeding according to the requirements is built into the most advanced servo automatic adjustment opening and closing mode.
Depending on the thickness of the material or the different types of materials, the device will automatically adjust to the matching position, which solves the problem that different materials need to be adjusted for a long time in the past, greatly reducing the material cost and time cost wasted due to the adjustment period.
Conventional materials may have the possibility that the roll itself will warp upward. In the past, users had to reinstall the material in the opposite direction to solve this problem. In order to solve this problem in this setting, we installed a pre-pressure device on the equipment.
| Power mode | Servo motor |
| Correction amount adjustment method | Servo CNC control |
| Correction amount display method | Digital display |
| Correction roller | 11 pieces, two groups of 5 upper and 6 lower, roller diameter 84mm |
| Pre-pressure roller | 3 pieces |
| Length roller | 2 pieces, 1 upper and 1 lower, roller diameter 120mm |
| Servo method for roller | Side gear drive |
| Training wheels | 2 columns |
| Auxiliary wheel bearing | Aligning bearings |
| Roller material | High-quality bearing steel, after hardening treatment, the hardness can reach HRC60±2 |
| Feeding repeatability | 0-1000mm ±0.15,>1000mm ±0.25 |
| Maximum feeding speed | 16m/min |
(4)Hydraulic cylinder lifting
The hydraulic lifting bridge facilitates workers to load and unload materials alone, and the entire process does not require touching, it greatly reducing the risk of cuts and other work-related injuries; after the material enters the leveling machine, the bridge is lowered to the lowest point and serves as a material bracket.
The upper layer of the device is entirely made of stainless steel, which effectively reduces friction on the material surface and protects the material surface from damage.
