It is equipped with guiding axis (27) into hole (26), the splice plate curved surface forming limit plate (15) is under the adjusting for adjusting screw rod (21)
It is moved left and right along guiding axis (27).
7. a kind of spherical surface splice plate hyperboloid forming method characterized by comprising
Step 1) passes through the setting height of adjusting screw rod (14) adjusting upper roll axis (1), is adjusted according to spherical surface splice plate (28) thickness
Clearance distance between upper roll shaft (1) and the first lower roller shaft (2) and the second lower roller shaft (3)；
Sheet width when the spherical surface splicing plate that step 2) measurement is cut does not form, is adjusted by controlling to adjust motor (23)
The width for saving two pieces splice plate curved surface forming limit plate (15) is consistent with sheet width；
Step 3) calculates the width of the spherical surface splice plate (28) after splicing plate curved surface forming according to spherical radius, is added by adjusting
Width adjusts arc plate (18) in the position of the 2nd 3/4 arc plate (17), and two pieces is widened to the width and ball adjusted between arc plate (18)
The width adjusting of face splice plate (28) is consistent；
Step 4) starts motor (10), by the spherical surface cut splicing plate between upper roll shaft (1) and the first lower roller shaft (2)
It is put into two splice plate curved surface forming limit plates (15), passes through upper roll shaft (1) and the first lower roller shaft (2) and the second lower roller shaft
(3) spherical surface splice plate (28) are squeezed into.
8. a kind of spherical surface splice plate hyperboloid forming method according to claim 7, which is characterized in that further include step
5), every formation of lots spherical surface splice plate (28) is at least through extrusion forming three times.
