The invention provides a method for machining a slender hole part through a cold heading technology. The method comprises the following steps of A, setting seven process stations, specifically, a, a cutoff station; b, a first shaping station; c, a second shaping station; d, a large hole punching station; e, a shrinkage station; f, a third shaping station; g, a waste discharging station; B, making a die: the die comprises a main die (2), a die shell (3) and a male die stamping rod (1), and the die shell (3) is arranged on the main die (2) in a sleeving mode; an inner die (7) is arranged below the main die (2), and the inner die (7) is in threaded connection with the die shell (3); a core rod (6) is installed at the central axis position of the main die (2) and the inner die (7) through a sleeve (5), and an ejector pin (4) is installed at the position, deviating from the axis of the core rod, of the bottom of the die; C, feeding materials into the die for molding; D, stamping once through a cold header to finish a stamping cycle; and E, completing cutoff, shaping and punching procedures of the raw materials in the die after stamping circulation, and obtaining a qualified part. According to the method, the cold heading technology is only used for direct molding, independent drilling procedures are reduced, the production cost is reduced, and the production period is shortened.
Description
Technical field[0001]The present invention belongs to the field of part processing, belonging to a forged part processing process of low removal material, and in particular to a method of processing elongated hole parts with a cold head process.Background technique:[0002]The existing elongated hole parts is a traditional molding method: first, the vehicle or cold rolled blanket; use the central drill to process the positioning hole, and then use the drill bit to punch through the process to obtain a slender hole. The process material utilizes low, low processing efficiency, large labor intensity, requires multiple processing equipment, and multiple processes can complete the part hole molding, and there is a problem of drill bits in the drilling process.Inventive content[0003]It is an object of the present invention to provide a method of processing elongated hole parts with a cold head process, which is used to process elongated hole parts by using a cold head processing method, im...
