Introduction to the structure of precision casting equipment manipulator
Manipulators are a type of product of precision casting equipment. After using them, they can greatly improve production efficiency. Today, the editor will introduce the structure of the production manipulator. The manipulator is mainly composed of three parts: actuator, drive mechanism and control system. The hand is a component used to grasp the workpiece (or tool). There are various structural forms according to the shape, size, weight, material and operation requirements of...
When wax is used as a pattern, investment casting is also called "lost wax casting". Investment casting usually refers to making a pattern out of fusible materials, coating the surface of the pattern with several layers of refractory materials to make a shell, and then melting the pattern and discharging it from the shell to obtain a casting without a parting surface, which can be filled with sand and poured after high-temperature roasting. Since the pattern is widely made of wax...
