Description

[Detailed Description of the Invention] This invention relates to a simple press device that can easily perform several kinds of notching operations on, for example, aluminum profiles.

Conventionally, when performing this type of notch processing, it has been carried out using a small hand press that operates a punch by levering the handle by manually operating the handle.

However, using a single press to process from several types to more than a dozen types of notches is extremely inefficient, as a separate press operation must be performed for each different shape of the machined part. There was a flaw.

In order to eliminate such problems, a method of installing a large number of presses in parallel can be considered, but in this method, when performing edge processing and intermediate processing of the shape material, it is necessary to prevent adjacent presses from interfering with the work. In order to do this, it is necessary to leave spaces between the presses, which is inconvenient and takes up a lot of space.

There is also a method of assembling several types of die sets into one press machine depending on the type of processing, but in this method, a large number of die sets are prepared on a storage shelf etc., and the die sets are changed for each different processing. Since the die set must be assembled, removed, and returned to the storage shelf, it not only takes a lot of effort and time, but also poses problems such as troublesome positioning when attaching the die set to the press section. there were.

This idea was made in view of the above circumstances. By equipping the die set with several types of gui and punch,
It is designed so that several types of press processing can be performed with one die set.It does not take up much work space, is lightweight, can perform several different types of processing at the same time, and saves the effort of assembling and removing die sets.
