Specific embodiment
The present invention is formed using the PCrNi3MoVQ material solid forging of function admirable, is guaranteed high-intensitive.Common oil cylinder one
As using 42CrMo material manufacture.
The present invention is described in detail with reference to the accompanying drawings.
Cylinder-shaped upper part of the invention has upper concave plane 1, and upper concave plane both ends form circle arc support 2.The arc-shaped branch
Support long 100-150mm, upper concave plane depth 200-300mm.In piston rod backhaul, when the oil cylinder involve power upward by formed punch, on
Two circle arc supports in portion can be contacted with super pipeline upper wall, to avoid oil cylinder shifts up and is damaged.
Referring to Fig. 3, the present invention is equipped with rectangle sink 3 on the concave surface of cylinder-shaped two sides, and rectangle sink length is than oil
The total length 100mm of cylinder, width is 100mm lower than upper concave plane, deep 25mm.Rectangle sink water storage is for cooling down oil cylinder.Rectangle
Sink is communicated by the cooling water pipeline 5 of perforation oil cylinder, is recycled in entire oil cylinder convenient for cooling water.Rectangle sink 3 and three
The water route that bar cooling water pipe is formed, cover and fastens using rubber seal rings for seal, then with steel plate, it is ensured that when oil cylinder normal work
Temperature is able to maintain at 45 ° -55 °.
Referring to Fig.1,3, the present invention is evenly distributed with spring ball 4 on the circular arc of oil cylinder bottom, passes in and out super pipe in oil cylinder
Reduce friction when road, when oil cylinder top is stretched, oil cylinder is retracted by reaction force, ball, and bottom great circle cambered surface is contacted with tube wall.
Referring to Fig. 4, oil cylinder upstream end of the present invention is in 15-45 ° of chamfering, and the long 40-80mm of chamfering facilitates access for super pipeline
It is interior.
It is cylinder-shaped high 5-15mm smaller than 8 internal diameter of super pipeline in order to guarantee that the present invention can smoothly penetrate super pipeline, it is long
800-1200mm, spacing is 200-300mm smaller than 8 diameter of super pipeline between the concave surface of two sides.
Referring to Fig. 2, there is the hole 6 passed in and out for piston rod 7 among upper concave plane.Referring to Fig. 5,7 head of piston rod has inverted T-shaped recessed
Slot 11, inverted T-shaped groove are matched with 9 bottom end convex block 10 of extruding punching head.
Referring to Fig. 4,5, piston rod 7 is connect with formed punch 9 used in hot extrusion using screw-in.When installing formed punch, convex block 10 is inserted
After entering inverted trapezoidal groove 11,90 ° of formed punch integral-rotation is convex to be caught in inside inverted trapezoidal groove fastly, makes formed punch and the firm company of piston rod
It is connected together.
Using the present invention: first formed punch 9 being mounted on cylinder piston rod 7, then oil cylinder is sent in super pipeline 8, is made
The center of formed punch and the center alignment of super pipeline pre-manufactured hole, open oil cylinder Water-cooling circulating, then will be around super pipeline pre-manufactured hole
Local heating is carried out, after heat preservation sufficiently, cylinder efficient pushes piston rod 7 at the uniform velocity to advance with formed punch 9, and super pipeline 8 is prefabricated
Hole hot extrusion molding is ozzle.
Cylinder structure of the present invention is compact, can be put into the hot extrusion molding that ozzle is carried out inside super pipeline, is guaranteeing 650T
While pressure, outer dimension is much smaller than pot type piston cylinder, sets water cooling pipeline in oil cylinder, can guarantee under high temperature environment for a long time
Work.Extrusion time can be shortened by carrying out super pipeline hot extrusion ozzle using oil cylinder of the present invention, improve extruding efficiency.
