Accompanying drawing explanation
Fig. 1 is the structural representation of drilling rod protective sleeve flanging apparatus for shaping of the present invention.
Wherein:
Top board 1, base plate 2, lifter plate 3, support 4, briquetting 5, interior pad 6, pressing plate 7, lead 8, gag lever post 9, counterdie 10, stretching buffer spring 11, compression buffer spring 12, hydraulic cylinder 13, stop nut 14, annular boss 15, annular flange groove 16, die shoe 17.
Detailed description of the invention
See Fig. 1; a kind of drilling rod protective sleeve flanging apparatus for shaping that the present invention relates to, it comprises top board 1, base plate 2, lifter plate 3, support 4, briquetting 5, interior pad 6, pressing plate 7, lead 8, gag lever post 9, die shoe 17, counterdie 10, stretching buffer spring 11, compression buffer spring 12 and hydraulic cylinder 13.Described lead 8 has four, described lead 8 is between the corner of top board 1 and base plate 2 four jiaos, the corner of described lifter plate 3 is sheathed on lead 8, described hydraulic cylinder 13 is arranged on top board 1 downwards, the telescopic end of hydraulic cylinder 13 connects lifter plate 3, the top of described briquetting 5 is connected with lifter plate 3, the top of interior pad 6 is connected with the bottom of briquetting 5, interior pad 6 is cylindrical structural, the external diameter of interior pad 6 is consistent with drilling rod protective sleeve internal diameter, described die shoe 17 is arranged on base plate 2, described counterdie 10 is arranged on die shoe 17, described gag lever post 9 has four, four gag lever posts 9 are upwards arranged respectively at the corner of die shoe 17, the top of described gag lever post 9 is provided with stop nut 14, the corner of described pressing plate 7 is sheathed on gag lever post 9, described compression buffer spring 12 has four, four compression buffer springs 12 are sheathed on four gag lever posts 9 respectively, compression buffer spring 12 is positioned at below pressing plate 7, described counterdie 10 top offers columniform die cavity downwards, the internal diameter of die cavity is consistent with drilling rod protective sleeve external diameter, the top of described counterdie 10 is provided with annular boss 15, the middle part of described pressing plate 7 is provided with circular channel, circular channel is used for passing through for interior pad 6, the periphery that the bottom of described pressing plate 7 is positioned at circular channel offers annular flange groove 16, the shape of annular flange groove 16 and annular boss 15 form fit, be drilling rod protective sleeve flanging shape, support 4 is installed on the below of lifter plate 3, stretching buffer spring 11 has two, two stretching buffer springs 11 are connected between the front side edge of pressing plate 7 and the front side edge of support 4 and between the back side edge of the back side edge of pressing plate 7 and support 4.Stretching buffer spring 11 comprises the first extension spring and the second extension spring arranged up and down, and the first extension spring is connected by drag hook with the second extension spring.Drag hook connected mode makes stretching buffer spring 11 only possess tensile resistance, does not possess resistance to compression.
