Label declaration: oil cylinder piston 1, cylinder cover 2, oblique cone convex surface stage body 3, oblique cone concave surface sleeve 4, screw thread dish 5, dial 6; Oil cylinder 7, adjusting knob 8, spring eye 9, lubricating oil gets into hole 10, steam vent 11, lubricating oil tap hole 12; Cylindrical shell 13, connector 14, circular hole 15, stopper slot 16, piece 17.
The specific embodiment
Pass through specific embodiment below, and combine accompanying drawing, technical scheme of the present invention is further specified.Should be appreciated that enforcement of the present invention is not limited to following embodiment, all will fall into protection domain of the present invention any pro forma accommodation and/or the change that the present invention made.
A kind of adjustable undergauge structure as depicted in figs. 1 and 2; The cylindrical shell 13 that comprise oil cylinder 7, is connected with oil cylinder; And be used to treat oblique cone convex surface stage body 3, oblique cone concave surface sleeve 4 and the screw thread dish 5 that the undergauge product carries out machinery control undergauge; Oblique cone convex surface stage body 3 is arranged at the inside of oblique cone concave surface sleeve 4 and cooperatively interacts with the scalene cone of oblique cone concave surface sleeve, and oblique cone concave surface sleeve is fixing with oil cylinder piston 1 through connector 14, and the screw thread dish is threaded with cylinder inboard wall and is adjacent with oblique cone convex surface stage body.Described oblique cone convex surface stage body 3 is to be put together by the rectangular trapezoidal piece 17 of several cross sections, and the middle part of oblique cone convex surface stage body is provided for placing the circular hole 15 of treating the undergauge product.
The number of piece 17 is 12 in the present embodiment.Have spring eye 9 on described 17, each piece connects through spring.Each piece has the stopper slot 16 that is used for fixing the undergauge mould towards a side of said circular hole 15.During the utility model work, treat to be provided with mould between undergauge product and the oblique cone convex surface stage body, the quantity of mould equates that with described mould is fixed on the stopper slot.
Body end surface is fixed with dial 6 and is used to control screw thread dish 5 and gets into the adjusting knob 8 of the barrel degree of depth, and adjusting knob 8 passes dial 6 and is fixed on the cylindrical shell, and dial is adjacent with the screw thread dish.When oil cylinder piston contacted with cylinder cover 2 fully, the degree of depth through adjusting knob change screw thread dish can change the gap between the adjacent piece, thereby changed the Circularhole diameter size.The wall of cylindrical shell is provided with lubricating oil and gets into hole 10, steam vent 11 and lubricating oil tap hole 12.Steam vent 11 and lubricating oil tap hole 12 are on the wall between connector 14 and the cylinder cover, and lubricating oil gets into hole 10 and is arranged on the wall adjacent with oblique cone concave surface sleeve 4.
Under the promotion of hydraulic power unit oil cylinder 7, oil cylinder piston 1 rise to top (be that cylinder cover 2 contacts with oil cylinder piston 1 fully, this moment oblique cone convex surface stage body 3 with the cooperation of oblique cone concave surface sleeve 4 under; The Circularhole diameter that is made up of a plurality of inwalls diminishes, and will treat that simultaneously undergauge product bore dwindles, and the whole active force of oil cylinder will be born by screw thread dish 5 this moment; Change the degree of depth that is screwed into of screw thread dish 5 through adjusting knob 8; Can change the gap between each piece this moment, the gap is big more, and it is big that the product behind the undergauge becomes; The gap is more little, and the product behind the undergauge is more little.As long as hydraulic pressure is much larger than the required pressure of product; And that screw thread dish 5 positions, oil cylinder piston 1 extended position are the mechanical system retaining is dead; Except that human factor, be difficult to change, so finally be screwed into effect of depth (at hydraulic pressure under the prerequisite of the required pressure of product) by what the external diameter of undergauge product only received screw thread dish 5.
Above-described embodiment is a kind of preferable scheme of the present invention, is not that the present invention is done any pro forma restriction, under the prerequisite that does not exceed the technical scheme that claim puts down in writing, also has other variant and remodeling.
