Detailed Description

The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings for a more complete, accurate and thorough understanding of the inventive concept and technical solutions of the present invention by those skilled in the art.

The die for installing the pipe fitting 4 comprises an upper die and a lower die, wherein the lower die comprises a lower die plate 1 and a female die 2, a pressing block 3 and a punch are installed on the upper die, and the pressing block 3 is matched with the female die 2 to press the pipe fitting 4. As shown in fig. 1-4, the utility model provides a floating mechanism of pipe type cut-out press, including slide wedge 7, slider 6, guider, plug 5, spring 13 and stop bolt 14, guider install in on the

lower bolster

1, 6 slidable mounting of slider are in on the guider is gone up the 4 tip openings of pipe fitting slide, 5 partly stretch into of plug 4 tip openings of pipe fitting and be equipped with drift complex

plug step hole

53, 5 another parts of plug with slider 6 passes through spring 13 and is connected, install above the slider 6 and pass 5 tip of plug stop bolt 14, slider 6 is kept away from die 2 one side is the inclined plane and is fixed with slide wedge 7, go up the mould install with slide wedge 7 complex tapered block 8.

The top of the sliding block 6 is provided with a mounting groove 16 towards one side of the pipe fitting 4, one part of the core rod 5 is a flat structure 51 mounted in the mounting groove 16, the other part of the core rod is a rod-shaped structure 52 matched with an end opening of the pipe fitting 4, the limiting bolt 14 is perpendicular to the flat structure 51, and the spring 13 supports the core rod 5 to float up and down along the limiting bolt 14.

The thickness of the rod-shaped structure 52 is smaller than the distance between the upper side and the lower side of the inner hole at the end part of the pipe fitting 4, and the edge of the end part of the core rod 5 extending into the pipe fitting 4 is in transition through a round angle.

Guider includes guide holder 10, slide rail 11 and pressure guide plate 9, guide holder 10 is fixed on the

lower bolster

1, 6 bottoms of slider with through slide rail 11 sliding connection between the guide holder 10, pressure guide plate 9 cross section is L shape, establishes along the slip direction symmetry lie in on the guide holder 10 slide rail 11 both sides, be equipped with pressure guide plate 9 sliding connection's chimb, 6 preceding terminal surfaces of slider pass through 2 sliding connection of die in nitrogen spring 12 and the place ahead.

The flat structure 51 is provided with a spring 13 through hole 54 for mounting the spring 13 and a bolt through hole 55 in sliding fit with the limit bolt 14, the bottom of the mounting groove 16 is provided with a spring 13 blind hole for mounting the spring 13 and a threaded hole for mounting the limit bolt 14, and the top of the spring 13 through hole 54 is sealed by a clamping block 15 or a screw after the spring 13 is mounted.
