DIE COMPONENTS |
|
|
|
|
|
Die components |
List the components that are found in various types of dies from simple two piece to progressive die sets. |
|
|
|
|
|
Identify die components on samples of dies or die sets and the purpose of each component. |
|
|
|
|
Die mating |
|
|
|
|
|
TYPES OF DIES |
|
|
|
|
|
Die categories |
List the major categories of dies and the type of industry that would use them. |
|
|
|
|
|
Describe variations of types of dies under each major category listed above. |
|
|
|
|
Die types |
Identify types of dies and sketch the shape of the part or describe the part that would be produced. |
|
|
|
TYPES OF PRESSES
|
|
|
|
|
|
|
Explain the five methods used to classify presses: source of power, ram, design of frame, method of applying power to ram and the purpose of the press. Give examples of each. |
|
|
|
|
|
List the factors that would influence selecting the type of press to use for a given job. |
|
|
|
|
|
Describe the following presses and list examples of products that would be produced on each: Inclined press, gap press, arch press, straight-sided press, horn press, knuckle-joint press, press brake, squaring shears, turret press, hydraulic press, transfer press, fourslide, drop hammer, steam hammer, rack and pinion, eccentric, power screw, cam and pneumatic. |
|
|
|
|
|
In the lab identify each type of press under as many classifications as possible. |
|
|
|
TOOL AND DIE DRAFTING
|
|
|
|
|
|
Theory |
Define draft and negative draft. |
|
|
|
|
|
Explain why draft is used in die design and for die patterns. |
|
|
|
|
|
Demonstrate how draft is incorporated into die patterns, tools, and die sets. |
|
|
|
|
|
Explain draft and how negative draft affects forging, forming and casting dies. |
|
|
|
|
|
Explain how die design and construction affects die life. |
|
|
|
|
Application |
Draw sets of common dies to specifications. |
|
|
|
RELATED MATH
