Description
Technical field
The present invention relates to a kind of punching pulling steel cylinder pipe wall thickness spinning method for correcting error, belong to the manufacturing technology field of high-pressure bottle.
Background technology
At present, known processes process with metal base making steel cylinder pipe is with the metal base heating, puts into punching hydraulic press die; Form the punching base to obstructed round counterbore of metal base centre punch with jumper bar, the punching blank outer surface is also circular, at once the punching base is put into pulling machine material feeding platform again; The push rod of pulling machine inserts in the punching base, at punching base front-axle beam pulling mould bases and device for discharging is installed, and can lay multiple tracks ring mould bases and roller die frame above it; The push rod of band punching base makes the punching base fast through ring mould bases and roller die frame under the promotion of main water vat, and it is rolling that the punching base of high temperature is carried out the axial pulling of multi-pass; Thereby process the steel cylinder pipe of end cap; The internal diameter of body is confirmed that by the push rod external diameter external diameter and wall thickness are confirmed that by ring mould and roller die the device for discharging that is installed in ring mould bases and roller die frame back is closed; Push rod rollback under the pulling of main water vat is deviate from the steel cylinder pipe of moulding from push rod, accomplish steel cylinder pipe processing.But steel cylinder pipe wall unevenness (like the steel cylinder of Φ 267mm wall thickness 5.8mm, wall thickness difference reaches 2.5mm), the surfaces externally and internally roughness of this technology mode processing are poor, directly influence the crudy of steel cylinder pipe.
Summary of the invention
For overcoming the deficiency of prior art; The purpose of this invention is to provide a kind of punching pulling steel cylinder pipe wall thickness spinning method for correcting error; The steel cylinder blank (1) of the tube body wall thickness ununiformity that punching pulling hot-working is gone out carries out spinning correction cold working again; In spinning correction process, the blank wall thickness deviation is corrected, thereby improved steel cylinder inner and outer round surface quality and wall thickness accuracy.
For realizing the foregoing invention purpose, the present invention adopts following technical scheme:
Punching pulling steel cylinder pipe wall thickness spinning method for correcting error of the present invention is as shown in Figure 1; It is characterized in that steel cylinder blank (1) cover is through on the inner spinning correction warp tool plug (2); Plug (2) is installed on the main shaft (7), and main shaft (7) is installed in the main spindle box (8), and spinning wheel (3) is that even distribution the in center is installed on the spinning wheel holder (4) with the rolling centerline; Diagram six spinning wheels (3) that have been divided into cloth; The spinning wheel number of other quantity that also evenly distributes, spinning wheel (3) can be with self centre of gyration rotations, and axial force and radial load can bear the spinning correction time.Spinning correction beginning after spinning wheel (3) touches steel cylinder blank (1) right part; In the spinning correction process; Do relative motion at rolling centerline direction steel cylinder blank (1) and plug (2) with spinning wheel (3) spinning wheel holder (4) assembly; Form the feed motion in the spinning correction process, can adopt following form to realize: steel cylinder blank (1) and plug (2) axial restraint, spinning wheel (3) spinning wheel holder (4) assembly moves; Spinning wheel (3) spinning wheel holder (4) assembly is fixed, and steel cylinder blank (1) and plug (2) move axially; Steel cylinder blank (1) and plug (2) all move and do simultaneously relative motion with spinning wheel (3) spinning wheel holder (4) assembly.
(Fig. 1 M-M is to view) steel cylinder blank (1) and plug (2) are made relative rotary motion with spinning wheel (3) spinning wheel holder (4) assembly on the rolling centerline circumferencial direction; Form the spinning motion in the spinning correction process; Can adopt following form to realize: steel cylinder blank (1) is active rotation under internal core rod (2) drives, and spinning wheel (3) spinning wheel holder (4) assembly does not change; Steel cylinder blank (1) and plug (2) do not change, spinning wheel (3) spinning wheel holder (4) assembly active rotation.
Spinning wheel (3) relatively rotates at steel cylinder blank (1) outer surface; Under the draught pressure of spinning wheel (3) and plug (2) outer surface; Utilize the plasticity of metal; By putting line, to pointwise steel cylinder blank (1) is cold worked into the tube wall (5) that spinning is rectified a deviation out to over glaze by line, after the whole spinning of the uneven wall thickness of steel cylinder blank (1) being rectified a deviation into the tube wall (5) that spinning rectifies a deviation out; Discharging rod (6) ejects the uniform steel cylinder of wall thickness from plug (2), accomplish steel cylinder blank (1) spinning correction processing overall process.
Like Fig. 1 M-M to shown in the view; With the roll line external diameters of the center and the tube wall (5) of rectifying a deviation out with six circumscribed circle decision spinning of (a plurality of) spinning wheel; The internal diameter of the tube wall that spinning is rectified a deviation out (5) is by the decision of the external diameter of plug (2); And external diameter is concentric in making in the spinning correction process, improves the steel cylinder pipe wall thickness accuracy.The concentricity of the circle that the external diameter of plug (2) and six (a plurality of) spinning wheels are circumscribed is guaranteed by equipment, tool processes precision and installation accuracy; Reach 2.5mm steel cylinder blank (1) after rotary pressing processing like Φ 271X8mm wall thickness difference; Can be processed into the steel cylinder of Φ 267X5.8mm; Wall thickness difference can be controlled in the 0.5mm; Steel cylinder blank (1) properties of product after rotary pressing processing significantly improve in addition, and institutional framework and the mechanical property of material all changes after the spinning, and the tiny and formation of grain size has fibrous characteristic; Intensity, yield strength and hardness all have raising, and intensity improves 60%～90%; Steel cylinder surfaces externally and internally roughness Ra value reduces.Reaching under the situation of identical performance, through the steel cylinder weight saving of spinning correction, for the vehicle-mounted gas cylinder of CNG, gas cylinder weight reduces and has significant meaning, and has reduced the consumption of steel cylinder material.
Like Fig. 5 is the partial enlarged drawing of deformed region I shown in Figure 1 portion; From figure, can find out; Spinning wheel (3) relatively rotates at steel cylinder blank (1) outer surface, under the draught pressure of spinning wheel (3) and plug (2) outer surface, utilizes the plasticity of metal; By putting line, to pointwise steel cylinder blank (1) is cold worked into the tube wall (5) that spinning is rectified a deviation out to over glaze by line.
The advantage of punching pulling steel cylinder pipe wall thickness spinning method for correcting error of the present invention is a steel cylinder blank (1) after spinning correction processing, and finished product steel cylinder wall thickness difference can be controlled in the 0.5mm; The institutional framework and the mechanical property of material all change, and grain size is tiny and form and to have fibrous characteristic, and properties of product significantly improve; Intensity, yield strength and hardness all have raising, and intensity improves 60%～90%; Steel cylinder surfaces externally and internally roughness Ra value reduces.Reaching under the situation of identical performance, through the steel cylinder weight saving of spinning correction, reducing the consumption of steel cylinder material, for the vehicle-mounted gas cylinder of CNG, gas cylinder weight reduces and has significant meaning, and the low more price of the gas cylinder weight of same performance is high more on the contrary.
