In fact, many times we are not concerned about the stretch of the tensile factor, in fact, this approach is not correct, why the concept of stretching coefficient, it is certainly the value of our val
(1) the production of tensile parts as far as possible the use of standard mold base, and norms of the type and specification of the mold frame on the decision of the type and specification of the nex
How to eliminate the residual stress of stainless steel drawing parts? Can sandblasting? The traditional aging methods are: thermal aging, vibration aging, natural aging, static overload aging, therma
The thickness of the plate will be the number of deviation problems, usually within the allowable range of deviation, metal stamping parts processing should be selected under the deviation of the plat
The main factors affecting the stability of the mold and stamping are: the use of mold materials; mold structural parts of the strength requirements; stamping material properties of stability; materia

Drawings on the design drawings Dimensions Note: tensile parts due to the size of the stress varies, so that the thickness of the material after stretching change. In general, the bottom of the centra
Stretch pieces of stainless steel by several times evenly stretched, the tensile accuracy of the pieces will be a great progress, if the failure in the early production process, but also its re-stretc
1, stamping direction to determine the direction of the punching direction of the part is to determine the stretching technology first encountered the question of whether it can not only decide to str

(1) a lot of time due to our tensile strength of the various parts of the different sizes, so we have the thickness of the material after the stretch will be more or less some changes. In general, the
The punching direction of the part is the first problem to be determined in the drawing process. It determines not only whether a satisfactory stainless steel drawing part can be drawn, but also how m
Stainless steel drawing pieces of the production process will be used to two kinds of plates, one is hot plate, a cold plate, in the course of the use of cold rolled sheet is most widely used, because
In many factories in the actual operation of the process found in the tensile part of the mold is easy to be strained, how we go to solve it. Today by our small pieces of stretching to the South to te
Stainless steel tensile spring: spring produced by ordinary spring tensile spring with good flexibility, electrical conductivity, wear resistance, normal temperature (temperature> 200 degrees) spring
The use of a progressive punching die or combination die in the automatic punching of a rotor, a stator plate, or in a connector operation is well known in the art of punching. In recent years, progre
