Determine the shape and size of the blanks of crane wheel forgings. In addition to attaching the blank margin to the corresponding processing surface of the part, sometimes it is necessary to consider the influence of process factors such as the manufacturing, machining and heat treatment of the blank. In this case, the shape of the blank may be different from the shape of the workpiece. For example, in order to facilitate installation during processing, some casting blanks need to cast the necessary process bosses, and the process bosses should generally be cut off after the parts are processed. Another example is the open and close nut shell of a lathe, which is composed of two parts into a casting, which is cut after a certain stage of processing to ensure the processing quality and convenient processing. Crane wheel forging manufacturer should push Shanxi Yongxinsheng forging. Its mass production and supply of crane wheel crane wheel forgings, supporting the production of wheels, pulleys, sprockets, piston rods, cylinders, shafts, etc.
Blank forgings of crane wheels are parts blanks obtained by forging. Forging is a processing method that changes the shape, size and mechanical properties of the blank to become a blank or part under the action of external force. Usually forging heats the metal blank.
How to determine the rough shape and size of crane wheel forgings?
Blanking method of crane wheel forging blanks: sawing; gas cutting.
Quality requirements for blank blanking of crane wheel forgings: blanking is based on the length of the blank, and the length is based on the short side between the two ends. The end face is flat and the inclination angle is less than 3 degrees.
Inspection content: material inspection, determine the inspection items, inspection methods, inspection percentages and performers according to the technical requirements for the materials; blank blanking quality inspection, determine the inspection items, inspection methods, inspection percentages and performers according to the blank blanking quality requirements.
Quality record, forging schedule, crane wheel forging process control record.
Blank crane wheel forging blanks can obtain continuous and uniform metal fiber structure after forging. Therefore, the mechanical properties of crane wheel forgings are good, and they are often used for important steel parts with complex stress. Among them, the precision and productivity of free crane wheel forgings are low, which are mainly used for small batch production and large crane wheel forgings. Model forgings have higher dimensional accuracy and productivity, and are mainly used for small and medium-sized crane wheel forgings with large output. Blanks with complex shapes are generally manufactured by casting methods, and thin-walled parts are not suitable for sand casting. For general-purpose stepped shafts, if the diameters of the sections are not different, round bar materials can be used; if the diameters of the sections are large, in order to reduce the material consumption and the labor of machining, forged blanks should be used. Large-sized parts are generally used. Choose free forging, small and medium-sized parts can consider the choice of die crane wheel forgings.
