Definitions

  • the present disclosure relates to terminal bending equipment, and in particular, to terminal bending equipment which is capable of correcting a bending angle even if components configured to bend a terminal are deteriorated.
  • a progressive processing (continuous processing) mold is spotlighted instead of a conventional single processing mold, so the use of the progressive processing mold is rapidly increasing. Simultaneously, the use range thereof is gradually expanding in various fields.
  • a material is transferred according to a process sequence
  • this is usually referred to as a sequential transfer type progressive die or a flow die.
  • this is also referred to as a multi-stage transfer type or gang die.
  • a desired terminal is made by sequentially performing a process while continuously transferring the terminal in a strip-shaped material having a length longer than a width.
  • each process is sequentially performed by a die and a punch installed to correspond to each other at respective positions of mold equipment, thus making a product.

  • the bending process may be rapidly performed regardless of the thickness of the terminal, thus leading to an increase in productivity as well as a reduction in manufacturing cost. Further, maintenance may be easily performed due to the configuration of a micrometer configured to move the insert body.
  • terminal bending device of patent document 1 is problematic in that, when components configured to bend the terminal are worn, deformed, or deteriorated through repeated production, the angle of a bent portion is changed, so the quality and reliability of a product are degraded.
  • the conventional bending device is problematic in that its size is large, so the bending device has many space restrictions.
