Accompanying drawing explanation
Fig. 1 is the structural representation of drilling rod protective sleeve in-flanges apparatus for shaping of the present invention.
Wherein:
Top board 1, base plate 2, lifter plate 3, lead 4, hydraulic cylinder 5, upper holder block 6, lower lock block 7, die shoe 8, dashpot 9, buffer rubber gasket 10, counterdie 11, drilling rod protective sleeve 12, gag lever post 13, stop nut 14, buffer spring 15, buffer board 16.
Detailed description of the invention
See Fig. 1; a kind of drilling rod protective sleeve in-flanges apparatus for shaping that the present invention relates to, it comprises top board 1, base plate 2, lifter plate 3, lead 4, hydraulic cylinder 5, briquetting, die shoe 8, dashpot 9, buffer rubber gasket 10, counterdie 11, gag lever post 13, stop nut 14, buffer spring 15 and buffer board 16.
Described lead 4 has four, four leads 4 are vertically arranged between the corner of top board 1 and the corner of base plate 2, described lifter plate 3 is between top board 1 and base plate 2, the corner of described lifter plate 3 is sheathed on lead 4, described hydraulic cylinder 5 is arranged downwards on top board 1, the telescopic end of described hydraulic cylinder 5 connects lifter plate 3, to the briquetting being arranged with stepped ramp type on lifter plate 3, briquetting comprises upper holder block 5 and lower lock block 6, the cross sectional dimensions of upper holder block 5 is greater than the size of lower lock block 6 cross section, the cylinder coincide with drilling rod protective sleeve 12 inner chamber sized by lower lock block 6, described die shoe 8 is arranged on base plate 2, described dashpot 9 is arranged on die shoe 8, described buffer rubber gasket 10 is arranged in dashpot 9, described counterdie 11 is arranged on buffer rubber gasket 10, die cavity is provided with in described counterdie 11, the size of die cavity and drilling rod protective sleeve 12 outline coincide, the bottom of die cavity is provided with in-flanges annular groove, in-flanges annular groove is used for placing for the in-flanges of drilling rod protective sleeve 12, described gag lever post 13 has four, four gag lever posts 13 are upwards arranged in the corner of die shoe 8, described buffer spring 15 is sheathed on gag lever post 13, described stop nut 14 is arranged at gag lever post 13 top, the corner of buffer board 16 is sheathed on four gag lever posts 13, buffer board 16 is between buffer spring 15 and stop nut 14, the centre of buffer board 16 be provided with one with the passage of lower lock block 6 form fit, this passage passes through for lower lock block 6.
Operation principle:
Drilling rod protective sleeve is positioned in counterdie, the in-flanges of drilling rod protective sleeve is positioned at in-flanges annular groove, primer fluid cylinder pressure, briquetting declines, lower lock block enters drilling rod protective sleeve inner chamber by passage, lower lock block continues to decline and carries out shaping to the in-flanges of drilling rod protective sleeve, now, exerting pressure due to the in-flanges of lower lock block to drilling rod protective sleeve makes pressure be passed to buffer rubber gasket by counterdie, buffer rubber gasket starts distortion, make to produce the first cushion effect during the shaping of lower lock block to the in-flanges of drilling rod protective sleeve, briquetting continues to decline, upper holder block contact buffer board, producing the second cushion effect between buffer board and buffer spring makes briquetting slowly press down.The dual superposition of the first cushion effect and the second cushion effect, make the in-flanges of drilling rod protective sleeve possess good stressed gradient when shaping, shaping effect is better.After shaping completes, hydraulic cylinder reclaims, and briquetting rises, if lower lock block and drilling rod protective sleeve interference fit cause drilling rod protective sleeve to be pressed down on block band, then, when briquetting rises, drilling rod protective sleeve is buffered plate and blocks, and automatically falls, and is convenient to blanking.
