elective lesson 2-3 Flashcards
The industrial art of manufacturing stamping dies, plastics molds, and jigs and fixtures to be used in the mass production of solid objects.
TOOL AND DIE MAKING
The fabrication of pressworking dies constitutes the major part of the work done in tool and die shops. Most pressworking dies are utilized in the fabrication of sheet-metal parts that range in size.
TOOL AND DIE MAKING
pressworking die consists of two sections, called
punch and die, or male and female
Both sections are mounted firmly in an electrically or hydraulically driven press.
punch and die, or male and female.
is the most common method used by tool & to cut or shape the material mostly using a Press.
Die design
are a cost-effective way to create customized products ranging from paper clips to advanced automobile parts.
dies
are responsible for manufacturing complex equipment like cutting tools dies, molds, and other machinery and parts.
Tool and die makers
The development of modern tools and dies can be traced to the American inventor and manufacturer____________, who first implemented the concept of the planned manufacturing of interchangeable parts.
Eli Whitney
mass producing firearms for the War of _______.

DIFFERENT TYPES OF TOOL AND DIE
Simple Die
Compound Die
Combination Die
Transfer Die
Progressive Die
Multiple Die
designed to perform only a single operation of each stroke of the press slide. Simple die can be further classified according to the functions such as cutting and forming.
Simple die or single operation die
are used in operations like trimming, notching, blanking and more. The forming die used in bending, and curling etc.
Cutting dies
die performs multiple operations like cut or punch can be done in one stroke. For example, it can perform cutting and forming operations simultaneously in one stroke. This very effective method for high-volume parts. ____________are used to stamp simple flat parts like washers.
COMPOUND DIE
In this type of dies, the cutting and bending operations are combined and carried out in a single operation. The cutting operation may include trimming, plercing, and blanking and is combined with noncutting operations like bending forming, etc.
combinations of different tool and die in one work station, parang per cycle
COMBINATION DIE
die uses a single press to operate multiple tools. In high volume production work, ________ comes with more advantages. It can freely transfer the work by adding more shape to the part until the metal workpiece achieves the final shape.
transferring to another operation in a same work station
TRANSFER DIE
widely used in producing various Industries parts, such as automotive and electronic, This type of die stamping consists of several individual workstations, each of which performs one or more different operations on the part.
Progressive die
has many unique benefits Including a high-speed production rate with low labor cost, the minimum amount of scrape, and this dies required only one setup to work.
progressive die
die is a punch press that produces two or more identical parts at a single stroke. A number of simple dies and punches are ganged together to produce two or more parts at each stroke of the press.
multiple or gang die
DIFFERENCE BETWEEN TOOL AND DIE
The easiest way to think of the difference between a tool and a die is simply that dies are a subset of tools-all dies are tools, but not all tools are dies, In metal stamping, a tool can be almost any mechanical device used to cut, form, support, or mold metals. By that definition, jigs and fixtures are tools, as are drills and cutting blades. Dies on the other hand are only those tools that functionally change the shape of the metal. Dies are typically the female components of a larger tool or press.
DIFFERENCE BETWEEN MALE AND FEMALE DIES
the male component is the protruding component, while the female is the depression or indentation.
the male portion will likely comprise multiple steel cutting or forming punches with the female portions matching the male pattern.
In the context of metal stamping, the male punch is driven into the die block to cut or form the workpiece or both
