Part relevant to the utility model is only schematically shown, they do not represent its practical structures as product.
As shown in Figure 1, 2, the utility model is a kind of coal mine hydraulic supporting cylinder barrel forge die, including great tonnage hydraulic
Machine 1, the tailpiece of the piston rod of the great tonnage hydraulic machine 1 are provided with movable punch unit, the corresponding position of movable punch unit bottom
It sets and is equipped with cavity plate unit；The punch member includes the upper mould fixed plate 2 for being located at the tailpiece of the piston rod of great tonnage hydraulic machine 1, on
The two sides of the bottom of mould fixed plate 2 are equipped with guide rail 3, and movable pad 4 is equipped between two guide rails 3, and the bottom of movable pad 4 is set
There is forging and stamping cylinder barrel punch-pin 5；The front end of two guide rails 3 is equipped with postive stop baffle 6, and the end of two guide rails 3 is equipped with oil cylinder fixed plate
7, oil cylinder fixed plate 7, which is equipped with, pushes oil cylinder 8, and the piston end of oil cylinder 8 is pushed to be connected with the side of movable pad 4；The forging and stamping
Cylinder barrel punch-pin 5 includes that punch body and the cylindrical type convex block 9 for being located at punch body bottom, the section of cylindrical type convex block 9 are straight
Diameter is less than the diameter of section of cylinder barrel；The cavity plate unit includes lower mold fixed plate 10, the top of lower mold fixed plate 10 and forging and stamping cylinder
The cylinder-shaped cavity plate backing plate 12 of cylinder cavity plate is connected, and forging and stamping cylinder barrel cavity plate includes cylinder-shaped cavity plate ontology 11, cylinder-shaped cavity plate
The bottom of ontology 11 is equipped with cylinder-shaped cavity plate backing plate 12, and the interior bottom of cylinder-shaped cavity plate backing plate 12 is equipped with the top with ejector rod oil cylinder 13
