Abstract
The utility model discloses an integral hydraulic cylinder, including cylinder (3) and jar seat (2), it still includes connecting plate (1), cylinder (3), jar seat (2) and connecting plate (1) form through forging whole shaping, jar seat (2) are the solid structure to the outside of jar seat (2) has connecting plate (1) that is used for being connected with outer attachment member, and connecting plate (1) is located the the central axis of cylinder (3). After the structure, need not to go on to weld the operation of cramming with this through -hole when follow -up assembly more than adopting, also do not have this department of cramming and still have the risk of leaking to the sealing performance of hydro -cylinder is stronger.
Description
Technical field
This utility model relates to the technical field of hydraulic jack, is especially a kind of integral hydraulic cylinder tube.
Background technology
At present, hydraulic jack is applied in all trades and professions, and according to different use occasions, the requirement to oil cylinder is also not
With.Traditional hydraulic jack includes cylinder barrel, piston, piston rod, cylinder seat and cylinder cap etc., and piston is connected also with one end of piston rod
Being slidably connected in cylinder barrel, cylinder seat and cylinder cap are connected to the two ends of cylinder barrel, and the other end of piston rod is sealedly connected on cylinder cap
On, its free end with hydraulic jack outside moving component be connected.It is therefore seen that, the operating pressure of cylinder tube is big, and impulsive force is also
Greatly, bearing alternating stress load for a long time, it is easy to fatigue damage, usual cylinder barrel is that the method using forging is processed.Due to
In prior art, cylinder barrel and cylinder seat are divided into two single parts, and both are linked together by electric welding, but, cylinder barrel and cylinder
Seat is forge piece, and weld seam is but as-cast structure, therefore destroys the globality of oil cylinder;Further, oil cylinder in a high voltage state,
Leakage is easily produced in commissure.
Therefore, occurring in that a kind of all-in-one-piece hydraulic jack cylinder barrel at present, it is by cylinder bottom and cylinder barrel one forging molding
Become.As disclosed on State Intellectual Property Office website, the patent of Publication No. CN201326725Y " tie by solid forging cylinder body
Structure ", it discloses cylinder barrel and cylinder bottom solid forging becomes an integrally-built cylinder body.But, it there is the problem that
One, this Integral hydraulic cylinder tube cylinder bottom part after shaping yet suffers from a through hole, in order to meet making of cylinder barrel
With requiring, need for cramming this through hole during follow-up assembling, such as welding, once through hole is crammed, the most as above
As the analysis stated, this place of cramming yet suffers from the risk of leakage;Second, the cylinder bottom part of some hydraulic jack not only plays
The effect of one capping, it is also a connector, such as articulated joint, and therefore, it also can not lead at one in cylinder bottom part
Hole, above-mentioned this structure the hydraulic jack of inapplicable this situation.
Utility model content
Technical problem to be solved in the utility model is to provide one, by solid forging, cylinder barrel and cylinder seat is linked as one
Individual entirety, and ensure the integral hydraulic cylinder tube that cylinder seat is normally connected with other connectors.
For solving above-mentioned technical problem, the integral hydraulic cylinder tube that this utility model provides, including cylinder barrel and cylinder seat,
It also includes connecting plate, and described cylinder barrel, cylinder seat and connecting plate is formed by forging global formation, and cylinder seat is solid structure,
And the outside of cylinder seat has the connecting plate for being connected with joint outer part, connecting plate is positioned on the central axis of cylinder barrel.
Described cylinder barrel is thin-walled cylinder barrel, and its length dimension is more than 20 with the ratio of wall thickness dimension, the cylinder base thickness of cylinder barrel
Spend equivalently-sized with cylinder wall thickness.
Described cylinder barrel is the little conical surface with the cylinder feather edge of cylinder seat junction, and its conical surface gradient is 8 °.
Described cylinder seat is the big conical surface with the lateral surface of cylinder barrel junction, and its conical surface gradient is 8 °.
The thickness of described connecting plate is 1:0.3 with the ratio of cylinder barrel cylinder base thickness degree.
After using above structure, this utility model compared with prior art, has the advantage that
1) due in the cylinder barrel of solid forging and cylinder bottom cylinder seating portion be solid structure, the most of the prior art logical
, therefore when follow-up assembling without carrying out carrying out welding by this through hole the operation crammed, the most there is not this place of cramming still in hole
There is the risk of leakage, thus the sealing property of oil cylinder is higher;
2) this structure is more applicable for the solid forging of some cylinder bottoms with interconnection function and cylinder barrel, and it is by entirety
Forging connector outside cylinder bottom is connected with miscellaneous part, thus bonding strength is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model integral hydraulic cylinder tube.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Wherein, 1, connecting plate;2, cylinder seat;3, cylinder barrel;4, the big conical surface;5, the little conical surface.
Detailed description of the invention
With detailed description of the invention, this utility model is described in more detail below in conjunction with the accompanying drawings.
From the structural representation of this utility model integral hydraulic cylinder tube shown in Fig. 1 and Fig. 2, it includes cylinder
Cylinder 3 and cylinder seat 2, it also includes connecting plate 1, and described cylinder barrel 3, cylinder seat 2 and connecting plate 1 is formed by forging global formation, cylinder
Seat 2 is solid structure, and the outside of cylinder seat 2 has the connecting plate 1 for being connected with joint outer part, and connecting plate 1 is positioned at
On the central axis of cylinder barrel 3.
Described cylinder barrel 3 is thin-walled cylinder barrel, and its length dimension and the ratio of wall thickness dimension are more than 20, at the bottom of the cylinder of cylinder barrel 3
Thickness is equivalently-sized with cylinder wall thickness.Such as, the wall thickness of cylinder barrel 3 is 7.5mm, and the thickness at the bottom of cylinder is also 7.5mm, its entire length
For 250mm.
Described cylinder barrel 3 is the little conical surface 5 with the cylinder feather edge of cylinder seat 2 junction, and its conical surface gradient is 8 °.
Described cylinder seat 2 is the big conical surface 4 with the lateral surface of cylinder barrel 3 junction, and its conical surface gradient is 8 °.
The ratio of 3 base thickness degree of the thickness of described connecting plate 1 and cylinder barrel is 1:0.3.Such as, the thickness of connecting plate 1 is
25mm, the cylinder base thickness degree of cylinder barrel 3 is 7.5mm.
The above, be only the most feasible enforcement example of this utility model, it is impossible to the most i.e. limit to of the present utility model
Interest field, for those skilled in the art, all utilization the technical solution of the utility model and technology design are made
Other various corresponding changes all should belong within this utility model scope of the claims.
