System for forming a T-shaped tubular fitting

摘要

The system for forming a T-shaped tubular fitting is configured for forming a T-shaped tubular part from an unbranched tubular part. The system includes an upper portion and a lower portion below the upper portion. A pushing block is disposed above the upper portion of the system. Compressible first and second side punches, respectively, extend from opposing sides of the upper portion. The upper portion includes a flat plate with a horizontal channel extending therethrough. The lower portion includes a housing with a vertical channel extending therethrough. The vertical channel extends normal to the horizontal channel. An insert can be disposed in the tubular part in alignment with the vertical channel. The horizontal channel and the vertical channel together define a T-shaped cavity. The T-shaped tubular fitting can be formed upon application of pressure to the pushing block.

主权项

1. A system for forming a T-shaped tubular fitting, the system comprising:
an upper portion and an opposing lower portion, the upper portion including a horizontal channel extending therethrough, the lower portion including a vertical channel extending therethrough, the vertical channel being normal to the horizontal channel, the horizontal channel and the vertical channel together defining a T-shaped cavity; a pushing block disposed over the upper portion, the pushing block including a concave lower surface; a tubular part configured for fitting within the horizontal channel, the tubular part having an aperture in a surface thereof; a first side punch and a second side punch positioned in the horizontal channel, the first side punch being adjacent one end of the tubular part and the second side punch being adjacent an opposing end of the tubular part; the first and second side punches having a tapered outer edge; wherein the concave lower surface of the pushing block engages the tapered outer edges of the first and second side punches; whereby upon vertical movement of the pushing block causes horizontal movement of the first and second punches; an insert having an aperture, the insert configured for positioning within the tubular part; a pull rod positioned within the vertical channel of the lower portion, the pull rod having a first end and an opposing second end; and a push rod extending between the pushing block and the upper portion.
