What is difference between punching and blanking?
At what temperature are cold working and hot working of metals separated?
Which sheet forming operations were used in the manufacturing process of the product shown in the figure?
Calculate the punch force F (N) required to complete blanking. Circle with diameter of 23.7 mm must be cut out of the material with 1.8 mm in thickness and 450 MPa tensile strenght.
where L - the total length sheared, mm; s - thickness of material, mm; τ1 (tau1) - shear strength of material, MPa; Rm - tensile strength of material, MPa.
Relative error +/- 1% allowed. Circle circumference is L=pi()*d.
Which sheet forming operations were used in the manufacturing process of the product shown in the figure?
Which sheet forming operations were used in the manufacturing process of the product shown in the figure?
Calculate clearance between the steel punch and the die z (mm). The material thickness is 1.1 mm, tensile strength 455 MPa, and the type of punch-dependent factor k is 0.01.
where k – punch material-dependent factor s – material thickness, mm; Rm - tensile strength, MPa; tau 1 (τ1) – material shear strength (τ1= Rm x 0.8), MPa.Provide the answer in millimeters with accuracy of three decimal places. Use "." as decimal separator.
