Specific embodiment
Case study on implementation one, referring to Fig. 1-6, the bending machine Pressure Block of adjustable angle, the Pressure Block include bottom plate, swinging block,
Connecting rod and rotational sleeve,
Symmetrical hinged two pairs of swinging blocks on the upper surface of the bottom plate pass through between the lower end inside of a pair of swinging block together
Gear engagement, on the inside of upper end between a respectively symmetrically hinged threaded rod, with the freedom of two threaded rods on a pair of swinging block
End is threadedly attached in the both ends of same root thread barrel respectively, adjusts the distance between two threaded rods by rotary screwing thread cylinder
To adjust the angle for adapting to different metal pipe bending with the angle between a pair of of swinging block, swinging block described in two pairs is same
The length direction level along swinging block is respectively corresponded between two pieces of swinging blocks on side and fixes two connecting rods, in every connecting rod
Piece matching rotational sleeve of coaxial package, the both ends of every rotational sleeve are bonded with the side of corresponding swinging block respectively,
Rotational sleeve can be relatively rotated with the variation of angle in metal tube bending process, converted rolling for force of sliding friction and rubbed
It wipes power and reduces friction, the middle of the rotational sleeve is equipped with a cricoid supporting table, the periphery of the supporting table
