The market competitiveness is reduced, so as to reduce economic benefit；The rough machined surplus of existing cylinder barrel is big simultaneously, is unfavorable for molding.
Utility model content
The technical problems to be solved in the utility model is：Overcome the deficiency in prior art, there is provided a kind of production efficiency is high,
Material consumption is little, can save raw material, reduce production cost, improve the market competitiveness, so as to increased economic benefit
High-voltage oil cylinder cylinder bottom.
This utility model solves the technical scheme adopted by its technical problem：A kind of high-voltage oil cylinder cylinder bottom, with cylinder
Copy for the record or for reproduction body, described cylinder bottom body include the blind hole for being opened in center position and the both ends of the surface being parallel to each other, the horizontal stroke of end face
It is connected in sequence to the profile in section by the first broken line, the second broken line, third fold line and fourth fold line, cylinder bottom body and cylinder
It is welded to connect by pad between cylinder body；The bottom face of the cylinder bottom body is provided with screw hole and oil filler point；Pad
It is sequentially connected by oblique line section and arc section and is constituted, the angle between oblique line section and vertical is 7.5 °, the circular arc of the arc section
Radius is 6mm.
Further, described cylinder body body carries out modifier treatment, and HB is 156～208.
Further, the bottom of described blind hole carries out fillet process, and its surface roughness is Ra3.2.
Further, described third fold line is arc section, and the radius of arc section is 6mm, the second broken line and fourth fold line
Between be parallel to each other, the first broken line be oblique line, which is provided with angle between horizontal plane.
Further, the first described broken line carries out fillet process with left side junction.
Further, described pad is sequentially connected by oblique line section and arc section and is constituted, between oblique line section and vertical
Angle be 7.5 °, the arc radius of the arc section are 6mm.
The beneficial effects of the utility model are：This utility model has production efficiency high, and material consumption is little, can save original
Material, reduces production cost, improves the market competitiveness, so as to increased economic benefit, the rough machined surplus of cylinder barrel in addition
It is little, it is easy to molding.Improve working conditions, reduce labor intensity, shorten labor time, increase yield.
Description of the drawings
This utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is left view of the present utility model.
1. cylinder bottom body in figure, 2. blind hole, 3. end face, the first broken lines of 3-1., the second broken lines of 3-2., 3-3. third fold lines,
3-4. fourth fold lines, 4. pad, 4-1. oblique line sections, 4-2. arc sections, 5. screw hole, 6. oil filler point.
Specific embodiment
This utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram only to show
Meaning mode illustrates basic structure of the present utility model, therefore which only shows the composition relevant with this utility model.
A kind of high-voltage oil cylinder cylinder bottom as shown in Fig. 1～2, with cylinder bottom body 1, cylinder bottom body 1 is included and is opened in
The blind hole 2 of center position and the both ends of the surface 3 being parallel to each other, the profile of the lateral cross section of end face 3 by the first broken line 3-1, second
Broken line 3-2, third fold line 3-3 and fourth fold line 3-4 are connected in sequence, by weldering between cylinder bottom body 1 and cylinder barrel body
Contact 4 is welded to connect, and cylinder barrel is originally provided with piston rod in vivo；The bottom face of the cylinder bottom body 1 is provided with screw hole 5 and oil filler point
6。
Cylinder body body 1 carries out modifier treatment, and HB is 156～208, and the bottom of blind hole 2 carries out fillet process, its rough surface
Spend for Ra3.2, third fold line 3-3 is arc section, and the radius of arc section is 6mm, between the second broken line 3-2 and fourth fold line 3-4
It is parallel to each other, the first broken line 3-1 is oblique line, and which is provided with angle between horizontal plane.
First broken line 3-1 and left side junction carry out fillet process, pad 4 by oblique line section 4-1 and arc section 4-2 according to
Secondary connection composition, the angle between oblique line section 4-1 and vertical is 7.5 °, and the arc radius of the arc section 4-2 are 6mm, are had
There is production efficiency high, material consumption is little, can save raw material, reduce production cost, improve the market competitiveness, so as to increase
Add economic benefit, the rough machined surplus of cylinder barrel is little in addition, it is easy to molding, improves working conditions, reduced labor intensity, shorten labor
