PRESS FORMING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240109114 titled 'PRESS FORMING METHOD

Simplified Explanation

The press forming method described in the abstract involves pressing an intermediate formed body with an intermediate ridge line portion into a target formed body using an upper die with specific features to prevent wrinkles.

  • Upper die with a step portion at the boundary between product and discarded portions
  • Discarded portion of the intermediate formed body includes separation, first contact, and second contact portions
  • Separation portion provides elongation allowance for discarded portion
  • First and second contact portions prevent wrinkles by contacting the upper die

Potential Applications

This technology can be applied in various industries such as automotive, aerospace, and manufacturing where precise forming of metal components is required.

Problems Solved

This technology solves the problem of wrinkles occurring during the press forming process, ensuring a smooth and accurate formation of the target body.

Benefits

The benefits of this technology include improved product quality, reduced waste, and increased efficiency in the forming process.

Potential Commercial Applications

Potential commercial applications of this technology include metal stamping, sheet metal fabrication, and production of complex metal components for various industries.

Possible Prior Art

One possible prior art could be traditional press forming methods that do not have specific features to prevent wrinkles during the forming process.

What are the specific features of the upper die in this press forming method?

The specific features of the upper die include a step portion at the boundary between the product and discarded portions, which helps in forming the target body without wrinkles.

How does the separation portion of the discarded portion provide an elongation allowance?

The separation portion of the discarded portion is spaced apart from the upper die at the initial stage of the forming step, allowing for elongation of the material without causing wrinkles in the final formed body.


Original Abstract Submitted

a press forming method includes a forming step of pressing an intermediate formed body including an intermediate ridge line portion with a large edge radius, into a target formed body. an upper die includes an upper die step portion at a boundary portion between a product portion and a discarded portion. the discarded portion of the intermediate formed body includes a separation portion which is spaced apart from the upper die at an initial stage of the forming step, to provide an elongation allowance for the discarded portion, and a first contact portion and a second contact portion which are brought into contact with the upper die at the initial stage of the forming step, to prevent occurrence of wrinkles.
