Abstract
The utility model provides a sealer for a main oil cylinder plunger piston of a forging press, comprising a cylinder cover cooperatively sheathed with the plunger piston, and a first seal ring, a second seal ring and an adjusting sleeve disposed between the plunger piston and the cylinder cover, wherein the first seal ring is disposed along with the inner wall at the bottom of the cylinder cover, the second seal ring is disposed above the first seal ring, and the adjusting sleeve is disposed above the second seal ring along with the inner wall at the top end of the cylinder cover. The sealer for the main oil cylinder plunger piston of the forging press is free of oil leakage and stable in structure due to the seal mode that the seal ring is combined with the adjusting sleeve.
Description
Technical field
The utility model relates to the hydraulic forging press field, relates in particular to a kind of Pressesforging master cylinder plunger sealing device.
Background technique
Fast forging machine is the forging machine that is in daily use in forging, because the machine of forging soon can reduce the heating number of times of forging, and has shortened the holding time of forging in the stove, greatly reduces the energy consumption of forging heating.High speed forging hydraulic press adopts integral frame pull-down structure, the plunger part of forging and pressing is arranged in the master cylinder, to-and-fro motion by plunger is forged and pressed object, the master cylinder head seals by end cap, the place that end cap contacts with plunger is provided with seal ring and seals, existing seal ring adopts O-ring seal, and oil leakage phenomenon takes place the sealing configuration instability easily.
The model utility content
In order to solve existing technical problem in the background technique, the utility model proposes a kind of Pressesforging master cylinder plunger sealing device, by the sealing means of seal ring and the combination of adjustment cover, avoid leakage of oil and structural stability.
Technical solution of the present utility model is: Pressesforging master cylinder plunger sealing device, its special way is: described seal arrangement comprise cooperate the cylinder cap of socket with plunger and be arranged on plunger and cylinder cap between first seal ring, second seal ring and adjust cover, described first seal ring is provided with along the cylinder cap bottom interior wall; Described second seal ring is arranged on the top of first seal ring; Described adjustment is set on second seal ring top, is provided with along cylinder cap top inwall.
Above-mentioned cylinder cap is the convex shape cylinder cap that reduces successively from the bottom to the top end diameter, and described cylinder cap base diameter is identical with the master cylinder diameter.
The above-mentioned inboard wall of cylinder cover setting and first seal ring, second seal ring and the adaptive groove of adjustment cover.
Pressesforging master cylinder plunger sealing device of the present utility model by comprising first seal ring, second seal ring and the cylinder cap form of adjusting cover, has been realized multi-stage sealedly, and the form that cylinder cap adopts convex shape has realized the plug-in type sealing, structural stability.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Embodiment
Referring to Fig. 1, Pressesforging master cylinder plunger sealing device of the present utility model, cylinder cap 3 is arranged on the head of master cylinder 2, master cylinder 2 is sealed, the inwall of cylinder cap 3 cooperates socket with plunger 1, first seal ring 4 is set between plunger 1 and cylinder cap 3, second seal ring 5 and adjustment cover 6, first seal ring 4 is along the bottom interior wall setting of cylinder cap 3, adjusting cover 6 is provided with along cylinder cap 3 top inwalls, adjusting cover 6 can realize regulating to cylinder cap 3, cylinder cap 3 inwalls can have and first seal ring 4, second seal ring 5 and adjust the adaptive grooves of cover 6, groove can be better overlap adaptively with seal ring and adjustment, do not have the structure of groove passable too; Cylinder cap 3 is cylinder caps of the convex shape that reduces successively from the bottom to the top end diameter, this structure can be better and plunger 1 and master cylinder 2 adaptive, can realize plug-type sealing, structural stability.
