Whole process is controlled by CNC digital control system.Structure is simple, easy to operate, high-efficient, and apparatus structure is compact.
Using a kind of rotary press modelling method of semielliptical rotary pressed head molding machine of the utility model, following step is specifically included
It is rapid:
Step 1, the not equal ellipsoids shell side journey in three sides is established, specifically:
x2/a2+y2/b2+z2/c2=1 (1)；
Wherein, a ≠ b ≠ c；A indicates ellipsoid shell in x-axis away from the distance of central point；B indicates ellipsoid shell in the y-axis direction
Distance away from central point, c indicate ellipsoid shell in the z-axis direction away from the distance of central point；
If a=1000, b=800, c=500, referring to Fig. 3 (a), Fig. 3 (b), the not equal ellipsoids shell side journey in three sides can be write as:
x2/10002+y2/8002+z2/5002=1, z ∈ [0,500] (2)；
Step 2, the equation of any single oval cross section is sought according to the not equal ellipsoids shell side journey in three sides of step 1 foundation, specifically
Process is as follows:
If single oval cross section is 1-1 ', if the z-axis size of section 1-1 ' is Z=c1, by Z=c1It substitutes into formula (2)
In ellipsoid formula, the elliptic equation of section 1-1 ' is obtained are as follows:
X2/[4(2500-c1 2)]+y2/[2.56(2500-c1 2)]=1 (3)；
X=ρ cos θ, y=ρ sin θ is enabled again, then formula (3) converts are as follows:
2.56ρ2cos2θ+4ρsin2θ=10.24 (2500-c1 2) (4)；
Wherein, any point on θ expression oval cross section 1-1 ' and the angle between oval x-axis positive coordinate, θ ∈ [0 °,
360 °], and θ is positive integer；ρ expression oval cross section 1-1 ' goes up any point to the distance of elliptical center；
ρ circular is as follows:
Assignment is carried out to θ respectively, θ is enabled to be respectively equal to 0,10 °, 20 ° ... 360 °, as long as each θ value is substituted into formula (4)
In to get each point on the corresponding oval cross section 1-1 ' of different θ out to elliptical center distance ρ；
When spinning, main shaft 4 drives material base 6 (material base 6 is Seal head blank) at the uniform velocity to rotate, if rotation speed is ω, then arbitrarily
The relational expression of material base 6 rotational angle θ and time t is in time t:
Θ=ω t (5)；
Then x=ρ cos θ, y=ρ sin θ converts are as follows: x=ρ cos (ω t), y=ρ sin (ω t),
Then formula (4) can be converted into following formula:
2.56ρ2cos2(ωt)+4ρsin2(ω t)=10.24 (2500-c1 2) (6)；
By establishing the relationship between ρ and t in formula (6), when main shaft 4 drives material base 6 at the uniform velocity to rotate any time t, rotation
13 projected position of pressure roller is to the positional distance ρ of 4 central point of main shaft, i.e., main when main shaft 4 drives material base 6 at the uniform velocity to rotate any time t
When axis 4 is moved left and right along 1 level of fixed pedestal, it is ensured that ρ meets the requirement of formula (6).
Step 3, using there is mould spinning process, the semiellipticals end socket inner tube of a tyre 5, the semielliptical end socket inner tube of a tyre are not waited in one three side of production
5 outer surface structures and size are consistent with the not equal Semi Ellipsoidal Shells interior wall construction in three sides and size；
Step 4, spinning prepares
According to the size dimension of semielliptical end socket, the horizontal position of main shaft 4 is first adjusted, then the semielliptical end socket inner tube of a tyre 5
It is mounted on main shaft 4, then being placed on the semielliptical end socket inner tube of a tyre 5 in 6 pairs of round material base, then material base 6 is pressed on pressure head 7
On the semielliptical end socket inner tube of a tyre 5；
Step 5, spinning sequence is determined
If there is N layers of oval cross section on semielliptical end socket, N is positive integer；
When rotary pressed head, start at the top of self-sealing head to divide plurality of layers oval cross section spinning from top to bottom, specific layering how much by
Technological design determines, at the top of head formed by spinning when first layer oval cross section, with the first layer oval cross section long axis rightmost side at the top of end socket
On the basis of vertex (positive direction of the x-axis and elliptical intersection point), spinning top second layer, third layer ..., n-th layer section it is oval
When, benchmark is similar；Referring to fig. 4, A, B, C point are respectively the datum mark of three layers of oval cross section of being connected in Fig. 4,1 in Fig. 4,2 ... N
Indicate the oval cross section number of plies；
The reference point location of i.e. any one layer oval cross section is this layer of oval cross section long axis rightmost side vertex position.
The base position of oval cross section is just arranged in the horizontal position of spinning roller 13, and spinning roller 13 is in entire spinning process
In, when moving to base position, the horizontal position of spinning roller 13 is no longer changed, and is in horizontal reference position always；
Main shaft 4 drive the semielliptical end socket inner tube of a tyre 5, material base 6, pressure head 7 movement respectively be rotation and along the x-axis direction front and back
It moves horizontally；
Step 6, start spinning
If the z-axis coordinate of N layers of oval cross section is ci, i=1,2 ... ..., N；c1< c2< ... < cN；
At the top of head formed by spinning when first layer oval cross section, servo motor B 16 drives lead screw 3 to rotate, and moving beam 2 drives master
Axis 4 is moved in the horizontal direction along lead screw 3, makes datum mark and the projection in the horizontal direction of spinning roller 13 of first layer oval cross section
Point position is overlapped, and then hydraulic cylinder B15 drives spinning roller 13 to be moved down into setting position, and lower mobile setting position is by first
The elliptical Z axis coordinate value c of layer cross section1It determines, after spinning roller falls in the reference point location of first layer oval cross section, is adjusted by step 5
The main shaft 4 of whole good position drives the semielliptical end socket inner tube of a tyre, material base 6, pressure head 7 to be rotated, and starts at the top of head formed by spinning the
One layer of oval cross section, in 4 rotary course of main shaft, horizontal shifting, main shaft 4 are moved horizontally apart from root main shaft 4 along the x-axis direction
It is determined according to the formula (6) in step 2, main shaft 4 rotates a circle, and first layer oval cross section completes spinning at the top of end socket, and main shaft 4 stops
Rotation；
When successively carrying out spinning to remaining N-1 layers of oval cross section, moving beam 2 drives main shaft 4 along lead screw 3 in level side
To movement, make datum mark and subpoint position of the spinning roller 13 on this layer of oval cross section of remaining N-1 layers of oval cross section respectively
(when carrying out spinning to second layer oval cross section, this layer of oval cross section refers to second layer oval cross section for coincidence；When to third layer
When oval cross section carries out spinning, this layer of oval cross section refers to third layer oval cross section, and so on, when to n-th layer elliptical cross section
When face carries out spinning, this layer of oval cross section refers to n-th layer oval cross section), hydraulic cylinder B15 is then passed sequentially through by spinning roller 13
C is moved down along the z-axis direction2、……cN, after spinning roller 13 successively falls in the reference point location of remaining N-1 layers of oval cross section respectively, press
According to the spinning process of first layer oval cross section, from the second layer to n-th layer oval cross section, successively to remaining N-1 layers of oval cross section into
Row spinning, after n-th layer oval cross section spinning is completed, semielliptical rotary pressed head is completed.
