Fully automatic PLC control system 1.5 meters pass-through steel plate pretreatment line Steel plate pretreatment line Uses:
The steel plate pretreatment line process refers to the processing process of surface blasting and rust removal and coating with a protective primer before the steel is processed (that is, the state of raw materials). The pretreatment of steel can improve the corrosion resistance of mechanical products and metal components, improve the fatigue resistance of steel plates, and extend its service life. At the same time, it can also optimize the state of the steel surface manufacturing process, which is conducive to CNC cutting and blanking. In addition, because the shape of steel before processing is relatively regular, which is conducive to mechanical rust removal and automatic painting, the use of steel pretreatment can greatly improve the efficiency of cleaning work, reduce the labor intensity of cleaning work and environmental pollution. Because of this, the steel plate pretreatment process has not only been popularized and applied in developed countries, but has also attracted increasing attention in many industries in China. Many companies have put the steel pretreatment process on the agenda of corporate technological transformation.
In order to comprehensively improve the usability and reliability of the product and meet the needs of users as much as possible, our company adopts the following key technologies and guarantee measures in the design of the steel plate profile pretreatment pipeline:
ˉ Workpiece conveying system The whole set of workpiece conveying system has stepless speed regulation by frequency conversion, which can not only run synchronously, but also each department can act independently. The roller of the shot blasting chamber is equipped with a special material wear-resistant jacket. The shot blaster is optimized and designed by computer simulation. The shots are fully utilized and the structure is compact and perfect.
Use primary cleaning + secondary air blowing
1. First-level cleaning: high-strength nylon roller brush + pill receiving spiral
2. Secondary air blowing: high pressure fan blows the shot twice in the shot blasting room (ash)
循环 Pill recycling purification
The most complete separated projectile full curtain type air separation separator is used. The projectile circulation system is set with an automatic alarm function for failure. If any failure occurs, the equipment automatically detects and protects.
ˉShot blasting dust removal system
The user can choose to use a bag filter. The dust emission of the bag filter can reach 50mg / m3.
The following is a real shot of the installation and commissioning of our steel plate pretreatment line:
The composition and working principle of the 1.5-meter pass-through steel plate pretreatment line is mainly composed of a roller conveyor system, a shot blasting cleaning machine, a shot blasting dust removal system, and an electronic control system. Its working principle is: it is sent to the closed shot blasting room by the conveying roller table, and the high-speed rotating impeller of the shot blaster is used to accelerate the wire cutting shot (shot) to the workpiece surface, and the workpiece surface is impacted and scraped to remove the workpiece. Rust and dirt on the surface, and then use the sweeping, rolling brush, shot-receiving spiral and high-pressure blow pipe to clean up the accumulated pellets and floating dust on the surface of the workpiece, and then send it out of the roller, so that the steel can achieve the purpose of rust removal and rust prevention.
