This article is intended to introduce basic tool making knowledge to junior toolmakers, die maintenance and press technicians. We will first define what is a stamping die and difference type of stamping dies exists in the market. Step by step introduce die component and it function and application. It will also discuss some terminologies use in the stamping industries such as cutting,

Basically,
2015 Cheap Air Jordan 10 Retro Chicago Bulls, Stamping operation is a cold working operation,
Sale Online Cheap Shoes Squadron Blue 13s, which mean that,
Buy Online Mens Air Jordan 11 Low Infrared 23, it runs under room temperature and no heat was introduced to the entire operation intentionally. However, heat is still generated from friction during the punching process. As such, proper lubricant needs to be applied during the stamping operation to reduces heat and wear rate of die members.

A stamping die is usually consists of a serious of precision punches and dies that cuts and forms sheet metal into a desired shape or profile within a specified dimension zone. The die members (punch and die) are typically made from special types of hardened tool steel. In some cases,

The part that the Die produced is called a piece part. eg. A key,

Types of stamping Die.

There are many kinds of stamping dies exist in the market, all of which perform a few basic operations,

The automatic Die we called a Progressive Die. Which consists of many operations within a Die. is perhaps the most common operation performed in a stamping die. The component to be cut is placing in between the punch and die. Desired shape and form is cut after two members bypass each other. Usually, the Die is bigger than the punch to allow smooth enter of the punch. The sizes difference between the punch and die are called the cutting clearance.

Cutting clearances change with respect to the type of cutting operation being performed,
Store Online Shoes Air Jordan 11 Bred 2012, the metal’s properties, and the desired edge condition of the piece part. The cutting clearance often is expressed as a percentage of the metal’s thickness. Different clearances applied to different material thickness and different type of material to be punched. The most common cutting clearance used is about 5 percent per side of the metal’s thickness. In general, the harder the material the bigger the cutting clearance will be applied.

High force is needed to perform the cutting operation. In general, the force required to perform the cutting operation we called it punching force and can be calculated as follow:
