Metal stamping parts mainly is the metal or nonmetal sheet, with the aid of the pressure of the press, through the stamping die stamping forming.
Hardware stamping factory main products are metal stamping tensile products, metal welding parts, machinery parts, another stent production of air-conditioning and air-conditioning accessories, metal products for automobile, motorcycle accessories and metal hardware accessories, has a strong mold development, manufacturing capacity.
Stamping if classified according to the process of forming and separation process can be divided into two processes.
Forming process of the index is to make the sheet metal under the condition of not to break the billet occurred plastic deformation, made into the required shape and size of the workpiece.
Separation process is also called the blanking, and its purpose is to make the stamping parts along the predetermined good overview line separation from sheet metal, at the same time guarantee the separation section of the character of the request.
In actual production, is often a variety of process integrated operating together in a workpiece.
Cutting, straight, shear, spinning, replace the stamping process is often used.
Stamping parts including mould correct installation and commissioning, strictly control the punch into the depth of the concave die, bending, cold extrusion, plastic and other process control correction mode of next check point sticking out, in a timely manner after grinding and research light chess sets of blade;
Keep the chess sets clean and reasonable lubrication and punch edge end fix the bevel or arc.
This is an effective way to slow down the blanking force.
Slow down the blanking force, can reduce the tensile force of the concave side material, thus suppressing stamping double material and torsion effect.
Dongguan metal stamping parts mainly has the following characteristics: the surface of the metal stamping parts stamping sheet and extension to listen to a great influence on stamping scrap quality, cried out to stamping data roughly, uniform thickness;
Surface light, no spots, no scar, no scratch, no surface crack, etc. ;
Obey the uniform strength, without taste preference;
Even unfold. angry rate is high;
Work hardening low;
Stamping parts with high dimensional accuracy, with the module size uniformity, good interchangeability.
Don't need to be further mechanical processing can satisfy the requirement of the general assembly and use;
Stamping is in the material under the premise of consumption is not big, the impact compression, with the parts of lightweight, good stiffness, and made the sheet metal by plastic deformation, metal lost to improve the internal structure of the layout of the strength of stamping parts forward;
Stamping parts in stamping process, due to the material inside is not affected by crushing, so have good inner quality, outside enjoying smooth good-looking, this inner spray paint, electroplating, phosphating and also the inner disposal to supply any conditions.
