The principle of alignment is for utilizing three point atress, exerts the power opposite with the work piece deformation direction through the straightener pressure head between two pressure-bearing supports, makes the work piece take place to surrender and warp, and the degree of difficulty is higher in the alignment is the alignment and controls the deflection simultaneously, prevents to take place to transship and leads to the work piece to scrap.
The prior straightening pressure-bearing support commonly adopts a fixed V-shaped supporting block. The defects of the straightening pressure bearing support are as follows:
before straightening, the position that the work piece contacted with V-arrangement pressure-bearing supporting shoe is two axial parallel lines, and when the straightener pushed down the work piece, the work piece formed three point stress state, and both ends perk, the work piece became point contact with the inboard marginal position of fixed pressure-bearing support this moment, if transship then be horizontal short line contact, because of the atress area reduction of contact surface, lead to stress concentration to exceed work piece surface strength, the work piece takes place the local deformation overproof.
Disclosure of Invention

Detailed Description
The following is a specific embodiment of the present invention, which will be further described with reference to the accompanying drawings.
Referring to fig. 1 to 4, the two sides of a pressure-bearing support base 4 of the straightening follow-up pressure-bearing support are step-shaped, the upper end surface of the pressure-bearing support base 4 is an arc surface, oil grooves 6 which are uniformly distributed are formed in the arc surface of the pressure-bearing support base 4, and grease is added into the oil grooves 6.
The lower end surface of the follow-up supporting block 2 is an arc surface, and the upper side of the follow-up supporting block 2 is an arc supporting surface. The arc surface at the lower end of the follow-up supporting block 2 is installed on the arc surface at the upper end of the pressure-bearing supporting base 4 in a matching way. Handles 5 are fixed on two side faces of the follow-up supporting block 2, and the handles 5 are high-strength bolts which are installed on the side faces of the follow-up supporting block 2 through threaded connection. Through the oil groove 6 and the butter on the arc surface of the pressure-bearing support base 4, the lubricating effect of the pressure-bearing support base 4 and the follow-up supporting block 2 can be improved, and the critical spherical surface abrasion can be prevented. The handles 5 on the two sides of the follow-up supporting block 2 facilitate the check of the consumption condition of the lubricating oil in the oil groove 6 of the pressure-bearing supporting base 4, so as to supplement the lubricating oil in time.
The two baffle sheets 3 are respectively fixed at the steps at the two sides of the pressure-bearing support base 4, and the upper ends of the baffle sheets 3 are provided with U-shaped limiting grooves. The high-strength bolts at two sides of the follow-up supporting block 2 are positioned in the U-shaped limiting grooves of the retaining pieces 3 at the corresponding sides. The moving range of the high-strength bolts 5 on the two sides of the follow-up supporting block 2 is limited in the U-shaped limiting groove of the baffle 3, and safety accidents caused by flying-out of the follow-up supporting block 2 in the rotating process are prevented.
The working principle is as follows:
as shown in fig. 2, the workpiece is in surface contact with the follow-up supporting block before alignment;
as shown in fig. 3, when the workpiece is straightened and bent, two ends of the workpiece will tilt, and when the workpiece rotates, the pressure of the straightening pressure head is transmitted to the pressure-bearing support base 4 to drive the follow-up support block 2 to rotate;
as shown in figure 4, in the moving process, the workpiece is always in contact with the surface of the slip 1 at the upper part of the follow-up supporting block 2, so that the stress concentration is prevented from increasing due to the reduction of the stressed area, and the local deformation is prevented from being out of tolerance.
This embodiment can both ensure that three stress point is located same axial vertical face at three-point bending alignment in-process, prevents to support the deflection and produces lateral torque to prevent that the work piece alignment process from producing more complicated twist, leading to the work piece to scrap.
