Forming aluminum on the press brake

Question: I encountered a bend problem, which confused me a great deal. I was using a die of 0.984 inch together with a punch of 0.03 inch. I dealt with 6061-T6 aluminum of 0.125 inch thickness. Since I experienced some cracks, I turned to 1100-O aluminum possessing defined extension force of 13.000 PSI. In accordance…

Grooving bending calculation formula

As depicted in figure 1, a grooving machine is needed to bend 20×20 square tubes of 1 mm thickness. The remaining groove thickness depends on the size of the bend of the rectangular arch and the thickness of the sheet (t). In general, if the sheet thickness is no more than 1 mm or equal…

Analyzing the k-factor in sheet metal bending: Part II

k-factor is the most significant among the math constants in sheet metal fabs. It seems the most basic value while calculating bending allowance (BA) and bending deductions (BD). If you gain the correct k-factor, your precise bending will be ensured.  A Slight Overview The neutral axle is a theoretic space that lies at 50% of…

The shear ease of cut-off parts

The Simplicity of Shearing Cut-off Parts Shearing plates by an iron-worker delivers simplicity. The sheet is placed in the area between the top and bottom blades. Once the ram pushes the top blades downwards to the fixed bottom blades, the sheet gets cut through the opposite cutters. Consider such factors as rake angles, clearance between…

Precision Sheet Metal Bending and the V groove

We have already represented the idea of the V-groove, an excellent alternative to create cosmetic bending featured with strong bending radius. Architectural panel bends featured with outer radii too close to the thicknesses of the materials and excellent appearance, with no cracks or crack traces provides evidence that it is a V-groove formation. V groove…
