Abstract
Hydraulic jack earthen pipe and flange welding structure, set positioning table one at flange welding, positioning table one a size of key dimension subtracts 0.3 to 0.8 millimeter, and tolerance is " 0/ 0.05 ", and welding chamfering Radius is 3.3 3.8 millimeters;Earthen pipe weld sets positioning table two, positioning table two a size of key dimension subtracts 0.3 to 0.8 millimeter, tolerance is "+0.05/0 ", welding chamfering two radius is 3.3 3.8 millimeters, this utility model cylinder barrel is to have been reprocessed with flange butt welding by earthen pipe, reaches to improve the purpose of welding quality by the Welding Structure size improving flange and earthen pipe.
Description
Technical field:
This utility model relates to a kind of hydraulic jack earthen pipe improving the defect after earthen pipe and flange welding and flange welding
Structure is relevant.
Background technology:
Add man-hour at hydraulic jack cylinder barrel, need to by earthen pipe and flange welding, then need by flange hole boring to in earthen pipe
The size that hole is identical, then carry out scraping rolling processing.Flange and earthen pipe structure are as shown in Fig. 1 Fig. 2, and flange A welding positioning table B is a size of
D-1.4 (+0.07/+0.02), welding chamfering C is R2.5, and earthen pipe D material is generally drawn tube, and earthen pipe hole size is the chi that dispatches from the factory
Very little D-0.8 (± 0.1), welding chamfering E is R2.5, and the cylinder barrel scrappage after welding shown in this kind of physical dimension is the highest, after scraping rolling
Inner hole of cylinder commissure pore a lot, badly influence the quality of weld seam, thus affect the intensity of welding, cause whole cylinder barrel
Scrap.
Summary of the invention:
This utility model aims to overcome that disadvantages mentioned above, it is provided that a kind of liquid improving the defect after earthen pipe and flange welding
Compressing cylinder earthen pipe and flange welding structure.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that
Hydraulic jack earthen pipe and flange welding structure, set positioning table one at flange welding, positioning table one a size of basis chi
Very little subtracting 0.3 to 0.8 millimeter, tolerance is " 0/-0.05 ", and welding chamfering Radius is 3.3-3.8 millimeter;Earthen pipe weld sets
Position platform two, positioning table two a size of key dimension subtracts 0.3 to 0.8 millimeter, and tolerance is "+0.05/0 ", welds chamfering two radius
For 3.3-3.8 millimeter.
Further, flange positioning table one a size of key dimension subtracts 0.5 millimeter, tolerance is " 0/-0.05 ", welds chamfering
Radius is 3.5 millimeters;Earthen pipe positioning table two a size of key dimension subtracts 0.5 millimeter, tolerance is "+0.05/0 ", and welding is fallen
Angle two radius is 3.5 millimeters.
Using technique scheme, this utility model cylinder barrel is to have been reprocessed with flange butt welding by earthen pipe, by changing
The Welding Structure size entering flange and earthen pipe reaches to improve the purpose of welding quality.
Accompanying drawing illustrates:
With accompanying drawing, this utility model is described in detail below:
Fig. 1 is this utility model existing flange generalized section;
Fig. 2 is this utility model existing cylinder barrel generalized section;
Fig. 3 is this utility model flange generalized section;
Fig. 4 is this utility model cylinder barrel generalized section.
Detailed description of the invention:
Below in conjunction with drawings and Examples, this utility model is described in detail:
It is embodiment of the present utility model as shown in Figure 3-4:
Hydraulic jack earthen pipe and flange welding structure, flange 1 weld sets positioning table 1, positioning table 1 a size of base
Plinth size subtracts 0.3 to 0.8 millimeter, and tolerance is " 0/-0.05 ", and welding chamfering 1 radius is 3.3-3.8 millimeter;Earthen pipe 2 welds
The place of connecing sets positioning table 2 21, and positioning table 2 21 a size of key dimension subtracts 0.3 to 0.8 millimeter, and tolerance is "+0.05/0 ", weldering
Connecing chamfering 2 22 radius is 3.3-3.8 millimeter.
Through the test of designer's thousands of times, sum up optimal embodiment, flange positioning table 1 a size of basis chi
A very little millimeter that subtracts 0.5, tolerance is " 0/-0.05 ", and welding chamfering 1 radius is 3.5 millimeters;Earthen pipe 2 positioning table 2 21 is a size of
Key dimension subtracts 0.5 millimeter, tolerance is "+0.05/0 ", and welding chamfering 2 22 radius is 3.5 millimeters.
This utility model be designer in practice, through repeated tests sum up form, seem simple, overcome one's own profession
Industry usual thinking for many years, changes to D-0.5 (0/-0.05) by flange with the positioning table size of welding of earthen pipe, welds chamfering
Changing to R3.5, earthen pipe welding chamfering is changed into R3.5 by R2.5, turning welding positioning table at cylinder barrel, a size of D-0.5 (+
0.05/0), the positioning table after turnery processing improves the corrosion of endoporus when former earthen pipe dispatches from the factory, and improves welding quality, additionally welds
Gap diminishes, and also reduces the generation of weld blowhole, and soldering angle R2.5 changes to R3.5, can be effectively shielded from weld seam,
Prevent stress from concentrating, it is ensured that welding base metal preferably through welding.
This utility model cylinder barrel is to have been reprocessed with flange butt welding by earthen pipe, by improving welding of flange and earthen pipe
Physical dimension reaches to improve the purpose of welding quality.This utility model is applicable to the production of hydraulic jack field large-scale, is
A kind of production efficiency height, good stability, structure that safety is good.
Described above illustrate and describes preferred embodiment of the present utility model, as previously mentioned, it should be understood that this practicality is new
Type is not limited to form disclosed herein, is not to be taken as the eliminating to other embodiments, and can be used for other groups various
Close, revise and environment, and can be in utility model contemplated scope described herein, by above-mentioned teaching or the technology of association area
Or knowledge is modified.And the change that those skilled in the art are carried out and change are without departing from spirit and scope of the present utility model, then
All should be in the protection domain of this utility model claims.
