Explosion-proof tool industry development status

Explosion-proof tools have been applied in special fields such as domestic petroleum, chemical, oil refining, oil and gas transportation as early as the 1980 s. However, since the domestic explosion-proof tool industry was not developed at that time, it could only be imported from abroad with foreign exchange, which was not abundant at that time. In order to allow customers to use our own explosion-proof tools, Hebei Zhongbo Explosion-proof Tools Co., Ltd. as the representative of the domestic production enterprises after several years of efforts and continuous practice, and finally manufactured domestic explosion-proof tool products. Over the past 30 years, China's explosion-proof tool manufacturers have always adhered to technological transformation and scientific and technological investment, and silently realized the dream of building China into a world explosion-proof tool manufacturing power through practical actions. According to industry insiders, at present, the explosion-proof tools made in China account for about 80% of the global market space, and the explosion-proof tools made in China occupy a certain position in the international market. According to customs statistics, the products of Hebei Zhongbo Explosion-proof Tools Group Co., Ltd. have reached more than 94.6 percent of the country's export of explosion-proof tools for five consecutive years. The company's domestic market share also reached more than 80%. According to the release of domestic explosion-proof tool manufacturing industry, Hebei and Tianjin are the most concentrated areas of explosion-proof tool industry, especially in Botou City. Botou not only has a large number of explosion-proof tool manufacturers, but also a large-scale explosion-proof tool professional manufacturer-Hebei Zhongbo Explosion-proof Tool Co., Ltd. is located here. At present, China's explosion-proof tool industry has entered the ODM independent design and production stage from the initial OEM OEM production stage. At present, China's explosion-proof tools have advanced manufacturing technology and have entered the fifth-generation product stage to gain a competitive advantage in the international market. ● The first generation of products, learn from the European Danish casting process, cast tire blank processing molding, to the market, to fill the national gap. Cast tire products have pores, trachoma, casting shrinkage, rough surface is not standardized, easy to bend, easy to shape, easy to break, short service life. Note: From 1983 to 1989, domestic materials were manufactured and 23 beryllium bronze smelting and production patents were obtained. ● Second-generation products. The surface of steel mold casting products was refined quickly, which solved the surface blisters and improved the quality of some products, but they were still steel mold casting tire products. In a product over phase. Note: From 1990 to 1998, domestic material manufacturing, creating beryllium bronze, aluminum bronze smelting and manufacturing process patents 28 third-generation products, precision casting process precision casting products, smooth surface, uniform density, no pores, no sand holes, improve the accuracy of the product, alloy mechanical properties, improve the competitiveness of domestic and foreign markets. Note: From 1999 to 2006, 36 patents for beryllium bronze and aluminum bronze manufacturing and appearance were created for domestic material manufacturing. ● The fourth generation of products. The die forging manufacturing process company successfully created the copper alloy die forging process, changed the production process of explosion-proof tools, and calendered them with six sets of friction presses of 150-4000T according to the tool size, creating many national patents. Advantages: high density, good toughness, smooth surface, clear handwriting, not easy to bend, not easy to break, uniform hardness, long service life. Note: from 2007 to 2016, the use of foreign Kazakhstan high-quality beryllium master alloy, and undisclosed matching method, enhanced the competitiveness of domestic and foreign markets, to export brand-name products, the world's top explosion-proof tools. Manufacturing beryllium bronze explosion-proof tools and aluminum bronze explosion-proof tools, obtaining 43 patents) ● Fifth generation products, intelligent precision forging manufacturing process selects imported raw materials, improves smelting matching method, newly enters 3 sets of die forging hammers and 4 sets of precision forging machines, beryllium bronze explosion-proof tools and aluminum bronze explosion-proof tools have all obtained EXIIC grade in the non-ignition test of the national testing station, and establishes the national CNAS laboratory and explosion-proof tool technology center. The explosion-proof tools produced by Zhongbo have surpassed various technical parameters in the international market, with appearance accuracy ≤ 6.3 μm, standardized, automated and intelligent production, full coverage of DIN standard die forging, novel appearance design, introduction of international advanced technology and automatic packaging of novel body. Note: Since 2017, 9 patents have been created.

Explosion-proof tool production process

Perhaps you are no stranger to explosion-proof tools (NonSparkingTools), but how to really ensure that customers can rest assured that the use of qualified explosion-proof tools is indeed a very rigorous thing. In your decades of working life, through a variety of different levels of hand tools, can you really care about, in the end how to produce explosion-proof tools (NonSparkingTools) its explosion-proof performance, mechanical performance can meet the standard and ensure that the national property and personal safety? 1. by the technical department to provide drawings that meet the requirements of the standard, mold development.

Explosion-proof tool material category

1. Beryllium bronze explosion-proof tools Beryllium bronze is a world-recognized explosion-proof tool manufacturing material. Beryllium is the basic alloy. When beryllium bronze is impacted at high speed or friction at high speed, its mechanical energy is converted into heat energy when it acts on the surface of the object, and the surface temperature suddenly rises. However, due to its high electrical conductivity and thermal conductivity, the heat of the working surface is quickly transferred to other parts of the workpiece, and the heat of the working surface is drastically reduced. Some particles that are detached from the workpiece under impact or friction are not at the temperature of the ignition source. Beryllium bronze intermetallic compounds are relatively stable, and the melting point is high, not easy to violent oxidation. Impact or friction at high speed

Explosion-proof tools Explosion-proof principle

Bronze alloy with copper as the main raw material has excellent thermal and electrical conductivity, strong corrosion resistance, good mechanical properties, suitable for mechanical processing, through solid solution and strengthening treatment, can meet the requirements of industrial strength, therefore, beryllium bronze alloy with copper as the main raw material is more and more used in industry, and modern industry puts forward higher requirements for the performance of beryllium bronze alloy, on the basis of the original development of beryllium bronze alloy forging process, improve the internal structure of beryllium bronze, enhance the density and torque, is the best material for the manufacture of explosion-proof anti-magnetic tools.

Explosion-proof tools using common sense

1. Explosion-proof tools-international nominal: safety tools and non-sparking tools. Users should choose qualified products approved by the state for explosion-proof performance inspection and testing, and carefully understand the scope of application, performance, characteristics, use methods and precautions specified in its instructions. 2, explosion-proof tools before use should identify the gas site, to determine whether the tools used to achieve its explosion-proof performance. 3, explosion-proof tools should not be used as ordinary tools in non-hazardous places, so as not to lose its due performance. Explosion-proof tools are high-strength and corrosion-resistant in most flammable gases. But it is not corrosion-resistant in all cases, such as wet ammonia, acetylene
