2022年1月1日 · Over the years, mechanical devices have normally been used that work in cold and perform cuts of metal or sheet metal by means of a die composed of the press and the …

To improve the quality of the cutting dies by using the ANSYS software, first the sheet metal cutting sequence is performed and by considering the calculation parameters of cutting round …

2023年2月24日 · Blanking and cutting of tubes is highly productive with small burrs in the cut. However, in order to prevent the tube wall from being flattened, a normal blanking die or shear …

The overall design and assembly structure diagram of the concave-convex mold is shown in Figure 4. 1- convex die fixing plate; 2- pillar; 3- spring; 4- concave die fixing plate; 5- concave...

Die Sheet Die Clearance FIGURE 7.12 Examples of the use of shear angles on punches and dies. Compare these designs with that for a common paper punch. (a) (b) (c) (d) Double-bevel …

The shear angle is obtained by processing the punch edge surface into a “convex” or “concave” shape, and is effective in. 1. Reduce tonnage. 2. Slug pulling. 3. Reduce noise. Popular shear …

Operations that induce shape changes on the workpiece by plastic deformation under forces applied by various tools and dies. Sheet metal forming technologies are challenged especially …

2022年5月20日 · Generally, the depth shall not exceed 3 times of the sheet metal thickness, i.e. h ≤ 3T. If the depth is too large, the convex hull is easy to deform or even crack. The slope of …

1999年4月15日 · Experimental results showed that the appearance of the punched hole for a small clearance between the punch and the die displays a great number of slips to extend …

2022年1月1日 · The present study aims to measure cutting parameters for sheet metal dies and to vary the use of round punches by elements with inclined, concave, and convex profiles. …
