Abstract
The invention relates to a method for processing a mark on a metal plate, which adopts a blanking method and utilizes the plastic deformation mechanism of the blanking to generate a bright belt with the thickness of 1/3-1/2 metal plates at the plastic deformation stage of the blanking. The mark processed by the process method has clear outline, simple process and low manufacturing cost of the die, and is particularly suitable for processing the mark on a medium plate or a metal material with poor formability.
Description
Technical field: the invention belongs to field of machining, relate to a kind of method that processing indicates on metal sheet.
Background technology: the traditional handicraft method of processing sign is an impression on metal sheet, and the formability that this process requirement metallic plate is thin plate and metal material is relatively good, as metallic plates such as 08A1, ST14.Be that traditional imprint process method seems unable to do what one wishes under the situation of formability difference of cut deal or metal material for metallic plate.In addition, adopt the desired die manufacturing cost of imprint process method processing sign higher.
Summary of the invention: the present invention can not be applicable to cut deal or relatively poor metal material and the high problem of cost of formability in order to solve traditional imprint process method, a kind of method that processing indicates on metal sheet is proposed, it is the method that adopts stamping-out, utilize the plastic flow mechanism of stamping-out, produce the euphotic belt of 1/3～1/2 sheet metal thickness in the plastic deformation stage of stamping-out.Use the sign clear-cut of process processing of the present invention, technology is simple, and die manufacturing cost is low, is particularly useful for the processing that indicates on the relatively poor metal material of cut deal or formability.
Description of drawings: Fig. 1 is the distortion schematic diagram in the strain stage of punching process;
Fig. 2 is the distortion schematic diagram in the plastic deformation stage of punching process;
Fig. 3 is a punching process process schematic diagram of the present invention.
The specific embodiment: stamping-out belongs to separation circuit in Sheet Metal Forming Technology, and whole stamping-out distortion separation process roughly can be divided into three phases: strain stage, plastic deformation stage, fracture separation phase.As shown in Figure 1 and Figure 2, what plate 1 at first took place in the punching process is strain, is plastic deformation then; Through the plastic deformation stage of strain after the stage, plate 1 produces plasticity detrusion 2 near protruding, cutting edge of die, form the shear band of light; The generation euphotic belt in plastic deformation stage is 1/3～1/2 sheet metal thickness, after this if punch continues to be pressed into and promptly enters the fracture separation phase, and this method mainly is to utilize the strain stage and the plastic deformation stage of punching process, to indicate processing on plate, the generation of the separation phase that do not need to rupture.Therefore for stoping the generation of fracture separation phase, the mould that is applied to this method is made up of punch 3, die 5 and cushion block 4, as shown in Figure 3, wherein cushion block 4 is identical with punch 3 shapes, be arranged in the die 5, and the difference in height of the end face of cushion block 4 and die 5 end faces is about 1/3～1/2 of sheet metal thickness.
Claims (2)
1, a kind of method that processing indicates on metal sheet is the method that adopts stamping-out, utilizes the plastic flow mechanism of stamping-out, produces the euphotic belt of 1/3～1/2 sheet metal thickness in the plastic deformation stage of stamping-out.
2, the method for processing sign on the metal sheet as claimed in claim 1, it is characterized in that: the particular manufacturing craft of described method is made up of punch, die and cushion block, it is identical with described punch shape that described cushion block is positioned at described die, and the difference in height of the end face of described cushion block and described die end face is 1/3～1/2 of a sheet metal thickness.
