Recently, Wuhu Xinxing Casting Tube has successfully developed a 2.6-ton cold bed machine body casting, which has passed the inspection and was successfully sent to the customer’s factory. Opened up new directions.
The cold heading machine is a special equipment for mass production of fasteners such as nuts and bolts, and the cold heading machine body casting is the main part of the cold heading machine, which has good compression resistance, corrosion resistance and good dimensional stability. sex. Compared with the previous castings of several hundred kilograms, the developed bed castings have achieved a new breakthrough in tonnage, and the design, shape and pouring difficulty of the gating system have all increased exponentially.
The research and development personnel of the laboratory joined hands to use the lost foam process to develop cold heading machine tool castings. The department quickly mobilized the technical backbones of various positions to actively participate in it, and worked together with the R&D personnel of the process room to analyze the drawings, formulate the mold group plan, CNC cutting and programming, design the pouring system, control the temperature of the molten iron, etc., and fully discuss and determine every detail. Through brainstorming and brainstorming, everyone finally formed a complete craft card. Under the guidance of the process room, the key issues such as how to prevent deformation and deep hole sintering in thick and large castings were repeatedly discussed, and multiple measures were taken to continuously improve the process plan to ensure the casting quality of large castings.
Through everyone’s hard work, in just a few days, the machine tool castings with a net weight of 2.6 tons, a height of 1.6 meters, and a partial wall thickness of 26 cm were successfully produced, and the mechanical properties and appearance quality of the blanks met the customer’s requirements.
