Abstract
Excavator hydro -cylinder cylinder end forging, it includes a discoid cylinder end physically, cylinder end body one side surface vertical be provided with the outer end limit for the cubic connection pad on semicircle limit, the both sides of this connection pad are provided with the disc of symmetrical evagination respectively to circular through -hole has been seted up at the center of both sides disc, at least side at the connection pad is equipped with cylindrical projection in addition, the opposite side surface of the cylinder end body is provided with a circular boss, the cylinder end body and this circular boss and integrative forging of connection pad form, just a cylinder end body side surface is formed with round transitional coupling limit or many the perpendicular ribs of being connected with the department of meeting of connection pad, the diameter that the connection pad thickness that sets up is greater than the cylindrical projection of connection pad side setting is gone up to the cylinder end body, just cylindrical projection sets up the junction between the connection pad and the cylinder end body to the evagination is in the cylinder end body, and wherein the axle centre bit of cylindrical projection is on the connection pad of cylinder end body top, it has simple structure, handling ease installation characteristic.
Description
Technical field
The utility model relates to a kind of excavator oil cylinder head forging, belongs to excavator oil cylinder technical field.
Background technique
Excavator oil cylinder head, it is the link of oil cylinder and outside parts, owing to there is structural design defect in existing oil cylinder head, thus overall processing inconvenience, load carrying capacity is low, very easily occurs fatigue in suffered shearing force and the larger position of pulling force, even there is the shortcomings such as crack, make whole oil cylinder head shorter for working life, serious meeting affects the normal use of oil cylinder, causes excavator job failure.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provides a kind of structure simple, and being convenient to processing installs, easy to use, load carrying capacity is good, and intensity is high, should not there is fatigue in each position, and can coordinate excavator oil cylinder head forging closely with other parts after machining.
The purpose of this utility model has been come by following technical solution, a kind of excavator oil cylinder head forging, it comprises a discoid cylinder head body, described cylinder head body one side surface is vertically installed with the block land that outer end edges is half round edge, the both sides of this land are respectively arranged with the disk of symmetrical evagination, and offer manhole at the center of both sides disk; Separately be provided with cylindrical projection at least one side of land.
The opposite side surface of described cylinder head body is provided with a round boss, described cylinder head body and this round boss and land one are forged and are formed, and described cylinder head body one side surface and the connecting part of land are formed with a circle transition fillet or many be vertically connected rib.
The land thickness that described cylinder head body is arranged is greater than the diameter of the cylindrical projection that land one side is arranged, and described cylindrical projection is arranged at the joint between land and cylinder head body, and evagination is in cylinder head body, wherein the axle of cylindrical projection is centrally located on the land above cylinder head body.
The utility model belongs to and improves the one of prior art, and it is simple that it has structure, and be convenient to processing and install, easy to use, load carrying capacity is good, and intensity is high, and each position should not occur fatigue, and can coordinate the features such as tight with other parts after machining.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is side-looking structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.Shown in Fig. 1,2, a kind of excavator oil cylinder head forging described in the utility model, it comprises a discoid cylinder head body 1, described cylinder head body 1 one side surface is vertically installed with the block land 3 that outer end edges is half round edge 2, the both sides of this land 3 are respectively arranged with the disk 4 of symmetrical evagination, and offer manhole 5 at the center of both sides disk 4; Separately be provided with cylindrical projection 6 at least one side of land 3.
Shown in figure, the opposite side surface of cylinder head body 1 described in the utility model is provided with a round boss 7, described cylinder head body 1 forges with this round boss 7 and land 3 one and forms, and described cylinder head body 1 one side surface and the connecting part of land 3 are formed, and a circle transition fillet 8 or many is vertical is connected rib.
The utility model preferred embodiment is: land 3 thickness that described cylinder head body 1 is arranged is greater than the diameter of the cylindrical projection 6 that land one side is arranged, and described cylindrical projection 6 is arranged at the joint between land 3 and cylinder head body 1, this cylindrical projection 6 evagination is in cylinder head body 1, wherein the axle of cylindrical projection 6 is centrally located on the land 3 above cylinder head body 1, and it can play reinforing function.
Excavator oil cylinder head forging described in the utility model, reasonable in design, intensity is large, load carrying capacity is high, be provided with the cylindrical projection of convenient processing clamping, land also overall block structure simultaneously, uniform force everywhere, decrease the probability of some privileged sites fatigues, effectively extend working life.
