Deep press sheet material

(1) For which metals is the deep drawing technique suitable?(Vereist)

Stainless steel/Steel/Inox/Copper/ Messing

Stainless steel/Steel/Aluminum/Inox

Stainless steel/Steel/Aluminum/Inox/Copper/Messing

2) Which of the following aspects play a role in shaping/forming a plate?(Vereist)

The choice of design process, based on or interacting with the product design.

The choice and influence of product material and tool material; machines and tools.

Both for the points mentioned at A and B.

(3) Which combination of the following factors, taken together, have the greatest influence on deep draw conditions?(Vereist)

Run-in radii, tensile gap, temperature, tool surface roughness, bending holding force?

Run-in radii, overly wide tensile gap, surface roughness of the tool, bending holding force?

Run-in radii, temperature, surface roughness of the tool, bending holding force?

(4) Statement A - Deep drawing technology provide constant accuracy by working with a metal or plastic upper and lower jig between which the product is formed. Statement B - Deep drawing technology allows working with smaller tolerances because it involves working with a metal or plastic upper and lower mold between which the product is formed.(Vereist)

A is correct, B is correct

A is false, B is false

A is false, B is correct

(5) What is meant in the deep draw technology by "the blenk"?(Vereist)

The material to be processed.

The "plooihouder".

The stamp

(6) Statement A - Deep drawing technology provide constant accuracy by working with a metal or plastic upper and lower jig between which the product is formed. Statement B - Deep drawing technology can easily integrate functional properties into the final product such as light weight, stiffness, cleanability, flow and design.(Vereist)

A is correct, B is correct

A is false, B is false

A is false, B is correct

(7) What is meant by " volgtrekken".(Vereist)

The process for the first operation.

The moment the sheet material is formed by the mould.

When a product is deep drawn this may have to take place in several press steps.

(8) When deep-drawing a product, the result must be determined beforehand. This can be roughly calculated and will usually have to be adjusted after a trial deep draw?(Vereist)

Smaller deformation forces, which increases the likelihood of cracking in the formed product wall.

Greater deformation forces, reducing the likelihood of cracking in the formed product wall.

Greater deformation forces, increasing the likelihood of cracking in the formed product wall.

(9) Select material types according to increasing tensile strength (Rm)?(Vereist)

Aluminum soft, copper, aluminum hard, steel (deep draw quality), stainless steel.

Copper, Aluminum soft, aluminum hard, stainless steel, steel (deep drawing quality).

Aluminum soft, copper, steel (deep drawn), stainless steel, aluminum hard.

10) Which of the following statement is correct when using a top and bottom mold in Ureol / plastic versus steel tools?(Vereist)

Total tooling costs are higher, highly suitable for larger series, accuracy of products is less constant.

Total tooling costs are lower, highly suitable for larger series, accuracy of products is less constant.

Total tooling costs are lower, less suitable for larger series.
