Stamping parts and machining process

by:Fortuna     2021-02-09
Stamping parts processing process: 1. According to the material, such as product structure determine the deformation amount of compensation. 2. According to the amount of compensation design mold stamping out finished or semi-finished products. 3. Processing semi-finished products to finished products. 4. Bad phenomena including crack, wrinkle, strain, uneven thickness, shape, etc. Tapping and thread processing: 1. Internal thread first drill base hole diameter and depth ( Bottom hole size according to thread specification size) ; External thread machining large diameter cylindrical to thread size (first According to thread specification size) 。 2. Processing thread: internal thread with corresponding grade tap tapping; Outside the thread with a thread cutter turning or die set of silk. 3. Bad phenomena including wire disorderly buckle, size is not uniform, unqualified thread gauge inspection, etc. Attachment: materials mainly selected according to the requirement of copper, aluminum, low carbon steel and other low deformation resistance, good plasticity and ductility good metal or nonmetal. Stamping is to rely on press and die for sheet, strip, pipe and profiles, such as external force, make its produce plastic deformation or separation, thus to obtain the required shape and size of the workpiece, Stamping parts) The forming method. Stamping and forging belong to plastic processing ( Or pressure processing) , called the forging press. Stamping of billet is mainly hot rolling and cold rolling steel plate and steel belt. Stamping parts mainly is the metal or nonmetal sheet, with the aid of the pressure of the press, through the stamping die stamping forming, it has the following characteristics: 1) stamping parts is on the premise of material consumption is not big, created by the stamping, light weight, good stiffness, its parts and sheet metal after plastic deformation, metal internal organizational structure to improve, to improve strength of stamping parts. (2) the size of the stamping parts with high precision, with the module size uniformity, good interchangeability. Don't need to be further mechanical processing to meet the requirements of the general assembly and use. (3) stamping parts in stamping process, due to the surface of the material are not destroyed, therefore, have good surface quality, smooth and beautiful appearance, for the surface paint, electroplating, phosphating and other surface treatment provides a convenient conditions. Stamping is power by means of conventional or special stamping equipment, the deformation of sheet metal in the mould is directly force and deformation, thereby gaining a certain shape, size and performance of the production technology of product parts. Sheet metal, stamping mould and equipment is processing of the three elements. Cold stamping processing is a kind of metal deformation processing method. So, called cold stamping or sheet metal stamping, stamping for short. It is plastic metal processing ( Or pressure processing) One of the main methods, also belongs to the material molding engineering technology. 50 ~ 60% of global steel sheet is made, most of this is after squeezing into a finished product. Car body, radiator, the steam kettle drum, container shell, motor, electric iron core silicon steel sheet in stamping process. Instruments and meters, household appliances, office, storage vessels and other mechanical products, there are a large number of stamping parts. Stamping is efficient production, the initiative to adopt composite die, exception is a multi-station progressive die, it can be finished in a pressure on multichannel stamping technical operation, complete material automatically generated. Generate fast, rest time is long, low production cost, collective per minute can be of production, popular with many factories. Stamping parts and castings, forgings, fights has the characteristic of thin, uniform, light and strong. Stamping can make this a master diameter is difficult to manufacture with enhanced, rib flanging, front, or artifacts, in order to improve its stiffness. Rejected due to the rough mould, workpiece precision can reach micron grade, and high precision, specification is consistent, can punching a hole nest, convex sets, etc. In the actual production, commonly used to approximate the manufacturability of stamping process test, such as deep drawing performance test, bulging performance test and other test materials stamping performance, in order to obtain the finished product quality and high qualified rate. Precision electronic technology co. , LTD is a professional stamping processing enterprise. Focus on production and processing precision shrapnel, metal terminals, hardware components such as tensile parts, lead frame. Products are widely used in the connector, micro motor, acoustic components, sensors, automotive electronics, new energy, medical electronics, intelligent household, diodes and IC packaging and other industries.
