    How to grind high-quality carbon steel plate

    Carbon steel sheets are widely used in many professional machinery equipment and large structural parts in the manufacturing industry, for example, in the engineering, energy and mining machinery industries, many products use steel sheets with a thickness of 6-20 mm. Some of these sheets are flat sheets without hollows, while most are sheets with 30% porosity. Their specifications and dimensions vary by product and use. After these carbon steel sheets are cut by plasma or oxygen, different degrees of flash, slag and burrs will be left on the cut surface. These must be removed, otherwise it will affect the aesthetics and usability of the finished product. Carbon steel plate Some enterprises perform artificial surface treatment on carbon steel sheets after thermal cutting, mainly using hand tools such as hand grinding wheels, scrapers, and steel hammers for knocking and sweeping. The disadvantages of this sanding method are: (1) Quality cannot be guaranteed. Manual grinding cannot guarantee the uniformity and thoroughness of grinding, and will affect subsequent bending, spraying and other processes, and affect the overall appearance and internal quality of the product. (2) The efficiency of manual grinding is difficult to master and count. It all depends on the work status and proficiency of the employee and cannot be guaranteed. (3) Environmental protection issues. The knocking brings dust and slag splashing, which seriously pollutes the air quality and environment inside and outside the work area. (4) There are certain security risks. In addition, the flying slag produced by grinding the workpiece and the handling of heavy objects are the main hidden dangers of personal injury accidents. In recent years, some companies have also tried to solve the slag and burr problems by mechanical means. In the current market, there are roughly two solutions. Carbon steel plate The first is the traditional dry single-sided grinding scheme. The workpiece is continuously ground by setting up multiple grinding heads on the top of the table. The grinding media used basically belong to the cloth-based abrasive belt and its modified grinding head. In this way, not only the cost of consumables is high, but also the time and frequency of replacing consumables will cause a huge waste of time. Also, generally speaking, the workpiece needs to be machined on both sides. With this single-sided grinding scheme, after single-sided grinding, the workpiece needs to be turned over to complete the final processing requirements, which greatly reduces the processing efficiency. The second is dry double-sided processing technology. Production line processing, the workpiece is clamped and ground by several sets of opposite clamping rollers. The advantages of this processing method can be described as: (1) The processing effect is good. No residual slag and burrs. The surface treatment effect of a single piece is the same as that of the whole batch of workpieces, which is unmatched by manual processing. (2) High processing efficiency. Using advanced double-sided simultaneous processing technology, the efficiency is increased by at least 60% compared with traditional processing methods. (3) Save a lot of human resources. For continuous processing on the production line, only two employees are needed for loading and unloading. (4) Energy saving and environmental protection. The production line is equipped with a high-efficiency dust removal system. The grinding dust is strictly controlled in the body, completely collected by the dust collector, and can be directly discharged after filtering. However, the high price of such a production line is undoubtedly a considerable expense for the majority of small and medium-sized enterprises.

    What kind of spot welding machine is used for carbon steel plate welding

    We know that the spot welding of carbon steel plate is excellent, and the welding parameter range is wide. In the common thickness range (0.5-3.0mm), no special measures are generally required. Using a one-way power frequency AC power supply, a simple welding cycle can achieve satisfactory results. Welding effect. What kind of spot welding machine is used for welding low carbon steel to weld high-quality product workpieces? Today, Xiaobian will come to briefly introduce the relevant knowledge of carbon steel plate welding. What spot welding machine is used for carbon steel plate welding: 1. Due to the good welding performance of carbon steel plates, when the plate is not thick and the welding requirements are not too high, the AC spot welding machine can be used to achieve the welding requirements. 2. If the equipment cost allows, try to use the medium frequency inverter spot welding machine to spot weld the low carbon steel plate, the welding effect is better, and the nugget and the welding point will be more perfect. In addition, no matter what kind of spot welding machine is selected to weld mild steel, we also need to pay attention to the following points. 1. Let’s start with the carbon steel plate itself. The cold-rolled steel plate does not need special cleaning before welding, and the hot-rolled steel plate must remove the oxide layer, rust, oil and other impurities on the surface. 2. If the capacity of the spot welding machine used allows, Sunar still recommends hard specification welding to reduce the influence of heat diffusion on the product and reduce product deformation. 3. For the electrode head material, we recommend choosing electrode materials with medium conductivity and medium strength, such as Cr-Cu or Cr-Zr-Cu alloy electrodes. 4. When the surface cleaning quality is poor or the stamping accuracy is poor and the stiffness is high, the measures of amplitude modulation current can be considered to solve the splash problem. Correct use of spot welding machine and reasonable welding of carbon steel plates can not only improve work efficiency, but also ensure the welding quality of carbon steel plates and improve product competitiveness. In addition, Sunar should add that when the thickness of the low carbon steel plate exceeds 3mm, the welding current is larger and the energization time is longer. In order to improve the working conditions of the electrodes, the welding method of multi-pulse welding current can be used to complete the welding of carbon steel plates. , so the effect will be better, and at the same time reduce the workload of the spot welder and prolong the service life of the spot welder.
