Engineering machinery and equipment industry
Adopting the hot melt drill chip free extrusion molding process, the hole and liner are formed in one processing, replacing the traditional drilling+welding/riveting process. Suitable for thin-walled structural components of excavators, cab frames of loaders
Intelligent robot
The robot joints and arms are thin-walled hollow structures to reduce weight, and traditional connection methods are difficult to ensure sufficient strength; Collaborative robots have high requirements for surface quality; Multiple varieties and small batches require high flexibility in processing plans. Huayi Tool's hot melt drilling solution forms holes and bushings on thin-walled hollow structural components in one go, and uses an extrusion tap for tapping to achieve high-strength, seamless threaded connections.
Automotive manufacturing industry
The manufacturing of automotive parts involves a large amount of connection and assembly of thin-walled pipes and plates. The traditional "drilling+welding nut" process has problems such as deformation of thin plates caused by welding heat affected zones, multiple processes, and shrinkage of threaded holes. Huayi Tool's hot melt drilling solution can complete the formation of holes and bushings in 2-6 seconds, with a thickness of 3-5 times that of the original plate. With the use of extrusion taps for tapping, it replaces the traditional welding nut process and eliminates welding thermal deformation.
Aerospace manufacturing
Aerospace thin-walled structural components are sensitive to weight, and traditional welding increases excess weight and creates a heat affected zone; High temperature alloy and titanium alloy drilling tools have short service life and high processing costs; High requirements for product traceability. The hot melt drilling solution of Huayi Tools adopts hard alloy material, which is compatible with titanium alloy, high-temperature alloy and other materials. The chip free processing avoids chip pollution, and the one-time formed liner meets the requirements of weight reduction and high-strength connection.
Rail transit manufacturing industry
The reliability requirements for thin-walled profile connections in rail transit vehicles are extremely high, and the traditional welding heat affected zone affects the fatigue life of the structure. The Ruiyi RUIYI hot melt drilling solution completes the hole and liner forming on the thin-walled profile of the vehicle body in one go, and forms a high-strength threaded connection with an extrusion tap to avoid welding heat effects and meet the connection requirements of rail transit structural components. Applicable scenarios: Body structural components, pipe connections for interior components, and assembly of thin-walled profiles for rail transit.
Metal furniture industry
Traditional welding nuts on stainless steel thin-walled pipes can easily cause deformation of the pipes and result in welding marks on the appearance; The cost of welding nuts is high, and they are prone to loosening after long-term use; Large batch size, low unit price, sensitive to individual processing costs. Huayi Tool's hot melt drilling solution forms a liner on stainless steel thin-walled pipe fittings in one go, and uses an extrusion tap for tapping, replacing the welding nut process, to achieve a high-strength threaded connection without welding marks.
Zhuzhou Huayi Tool Manufacturing Co., Ltd. is a high-tech enterprise specializing in the research and development, production, precision machining, and sales of hot melt drills, hard alloy material processing, hardware tools, and mechanical component processing.
