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 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.
