What should be noted about precision stamping process?
Stamping is to press and mold on the plate, strip, pipe and profile applied external forces, so that plastic deformation or separation, so as to obtain the required shape and size of the workpiece.Precision stamping parts made by precision stamping technology have the advantages of large size range, complex shape and high precision, and are widely used in various fields.However, the process of precision stamping parts is relatively complex. In order to ensure the forming effect of stamping parts, it is necessary to pay attention to the following process matters:
1. The number of working procedures of precision stamping parts mainly depends on the complexity of its structure shape and depends on the number of bending angles, relative positions and bending directions.When the bending radius of the bending part is less than the allowable value, a shaping procedure is added after bending.
2. The number of working procedures of precision stamping parts is related to material properties, drawing height, number of drawing steps, drawing diameter and material thickness, etc., which can only be determined by drawing process calculation.When the rounded corner radius of drawing part is small or the dimensional precision is high, it is necessary to add a shaping procedure after drawing.
3. The determination of the number of processes shall also be in line with the existing molding capacity and stamping equipment of the enterprise.Mold making capacity should be able to ensure that the mold processing, assembly accuracy corresponding to the requirements of improvement, otherwise only to increase the number of procedures.
4. When the section quality and dimensional accuracy of precision stamping parts are required to be higher, it can be considered to add dressing procedure after blanking or directly adopt the precision blanking procedure.
5, in order to improve the stability of precision stamping process sometimes need to increase the number of procedures to ensure the quality of precision stamping parts.For example, the additional location of bending parts in the process of hole punching, forming process of increased deformation to reduce the hole punching to transfer deformation areas, and so on.
6, blanking the shape of the simple precision stamping parts, using a single process to complete the mold.Blanking the workpiece with complex shape, because the structure or strength of the die is limited, its internal and external contour should be divided into several parts blanking, need to use a number of stamping procedures.
7, the use of special stamping oil can effectively improve the process accuracy, fundamentally put an end to rapeseed oil, mechanical oil, recycled oil and other non-special oil adhesive machine yellow robe, skin irritation and other problems.
There are many process steps of precision stamping parts, the staff should understand the matters needing attention of each step in detail, and strictly implement the operation procedure specification.
