Abstract
The present invention relates to a fitting bending apparatus with a pinching preventive function, and more specifically, to a fitting bending apparatus with a pinching preventive function that bends a short fitting having a length equal to or shorter than a predetermined length and has a structure in which fixing and release states of the fitting can be adjusted such that the fitting bending apparatus is not pinched between projecting portions of the fitting after bending is performed.
Claims3
A fitting bending apparatus with pinching preventive function that bends a fitting such that an inlet and an outlet have predetermined angles and that enables a bent fitting to be detached, the fitting bending apparatus with pinching preventive function comprising:
- a fitting seating unit having a groove formed in a predetermined arcuate shape with a predetermined curvature such that an outer circumferential surface of the fitting is seated;
- a release unit having a predetermined fixing and releasing structure, which is disposed on one side of the fitting seating unit, is fixed during a process of bending the fitting, and is transported to be separated from the groove of the fitting seating unit to provide a space for the bent fitting to be detached after the process of bending the fitting;
- a transport shaft that provides a path along which the release unit is transported and that is disposed in a direction perpendicular to a plane including an arc forming the groove of the fitting seating unit;
- and
- an adjustment jig that is disposed above the transport shaft and adjusts switching between fixing and releasing states of the release unit,
- wherein
- the end portion of the fitting is releasable after the process of bending the fitting, wherein the release unit includes:
- a seating extension portion having an extension groove forming a part of the groove of the fitting seating unit;
- and
- an independent groove structure that is disposed, as a component independent from the groove of the fitting seating unit, above the seating extension portion and has a groove formed to correspond to the extension groove in a state of being in close contact with the seating extension portion, and
- wherein the transport shaft includes:
- a support shaft fixed on one side of the seating extension portion;
- a spring that is connected to the support shaft and applies an elastic force upward to the independent groove structure;
- and
- a hook preventing the independent groove structure from being detached from the transport shaft.
