However, with this processing method, it is easy to cause the round hole to be over-positioned, the positioning burr of the inner hole is too large, and it is difficult to take and place; after the artificial ear is punched, it will be retained on the positioning pin, and the waste cannot be discharged in time; NC processing does not need to use the round hole on the false ear for positioning. Reserving the fine blanking process to the post-process will increase the man-hour and cost of NC processing

Embodiment Construction
[0016] The technical solutions of the present invention will be further described below through specific embodiments.
[0017] A metal processing method, comprising the steps of:
[0018] S1: A die-casting mold is used to die-cast a metal blank with two oppositely arranged false ears, and positioning holes are formed on the sides of the two false ears facing away from each other;
[0019] S2: Using a punching die, use the two positioning holes of the metal blank in S1 for positioning, then punch the shape of the metal blank; punch out the two false ears while punching the shape, so as to obtain a metal part .
[0020] Specifically, in S1, the process parameters during die-casting, such as punch speed, filling time, pressure holding time, pouring temperature, die-casting mold temperature, etc., need to be adjusted according to the material and thickness of the metal used in practice. s Choice. Among them, the positioning holes formed on the two artificial ears are preferably...

Abstract
The invention relates to the technical field of metal processing, and particularly discloses a metal part processing method and a metal part. The metal part processing method comprises the steps thatS1, a die-casting die is adopted, a metal blank piece with two oppositely-arranged false lugs is formed in a die-casting mode, and positioning holes are formed in the side faces, away from each other,of the two false lugs correspondingly; and S2, a punching die is adopted, after positioning is carried out by means of the two positioning holes of the metal blank piece in S1, shape punching is carried out on the metal blank piece, and the two false lugs are punched while the shape punching is carried out, so that the metal part is obtained. According to the metal part processing method and themetal part, a processing process of the metal part can be simplified, the processing difficulty is reduced, and the processing precision is guaranteed.
Description
【Technical field】 [0001] The invention relates to the technical field of metal processing, in particular to a method for processing a metal part and the metal part. 【Background technique】 [0002] Metal manufacturing (metal craft) is a technology that processes metal materials into objects, parts, and components, including large parts such as bridges and ships, and even tiny components of engines, jewelry, and watches. It is widely used in different fields such as science, industry, arts and crafts. Common metal parts processing techniques include: machining, stamping, casting, forging, welding, powder metallurgy, metal injection molding, etc. [0003] For existing metal parts, such as the internal components of mobile phones, LCD screens, notebook computers, tablet computers, etc., the usual processing method is: first perform die-casting to obtain a blank with artificial ears, and then perform one or more times Mechanical processing, and finally cut off the false ear to ...
