Abstract

A kind of straightener eliminating residual stress in composite plate, belong to composite plate aligning mechanical field, it includes the joining rails between front straightener, rear straightener, front and back straightener and drives the PWTN of front and back straightener running to unify and regulates the screwdown gear of drafts, feature is: the working roll arrangement mode of front straightener is the centre that a upper straightening roll is arranged in roll shaft, and under left and right, smoothing roll is arranged in the left and right sides of roll shaft respectively; The working roll arrangement mode of rear straightener is the left and right sides that left and right upper straightening roll is arranged in roll shaft respectively, and a lower smoothing roll is arranged in the centre of roll shaft; All smoothing rolls can left and right adjusting on roll shaft, and the circular arc composition of multistage different curvature that roll surface adapts by the plate shape after bending with composite plate.Advantage is: can eliminate the residual stress in composite plate.

Description

A kind of straightener eliminating residual stress in composite plate

Technical field:

The invention belongs to composite plate aligning mechanical field, be specifically related to a kind of straightener eliminating residual stress in composite plate.

Background technology:

At present, composite plate employed both at home and abroad is by welding mostly, the methods such as rolling are made, but so the composite plate that no matter uses which kind of method to produce is by being composited by two kinds of unlike materials, the coefficient of expansion of bi-material is different, composite board internal can be caused to produce residual stress, after composite plate is said good-bye, due to the release of residual stress, make composite plate generation buckling deformation, this aligned it before saying good-bye with regard to needs, eliminate the residualinternal stress in composite plate, the mechanical device of residual stress in a kind of effective elimination composite plate of current shortage, cause composite plate rolling say good-bye after produce flexural deformation.

Summary of the invention:

The object of this invention is to provide a kind of straightener eliminating residual stress in composite plate, effectively can eliminate the residual stress in composite plate.

The present invention realizes like this, as accompanying drawing 1, shown in, it includes the joining rails III between front straightener I, rear straightener II, front and back straightener I, II and drives the PWTN of front and back straightener running to unify and regulates the screwdown gear of drafts, it is characterized in that: as shown in Figure 2, the working roll arrangement mode of front straightener I is the centre position that a upper straightening roll 3 is arranged on roll shaft, in front straightening machine frame 1, and under left and right, smoothing roll 4,4 ＇ to be arranged on lower roller shaft, in front straightening machine frame 1 on position, the left and right sides respectively; After shown in Fig. 3, the working roll arrangement mode of straightener II is that left and right upper straightening roll 5,5 ＇ is arranged on roll shaft, in rear straightening machine frame 2 on position, the left and right sides respectively, and a lower smoothing roll 6 is arranged on the centre position on lower roller shaft, in rear straightening machine frame 2; Smoothing roll on the straightener of front and back can make left and right adjusting on roll shaft, the roll surface of all smoothing rolls by with the composite plate flexural deformation of different in width after the circular arc of multistage different curvature that adapts of plate face shape form, which increase the contact area of aligning roll surface and composite plate, avoid producing impression in composite surface.

Advantage of the present invention and good effect:

1. the present invention arranges by adopting the difference of forward and backward working roll group, the longitudinal direction of composite plate applies forward and reverse drafts respectively in order to eliminate the residual stress in composite plate, ensure composite plate say good-bye after flatness, be conducive to improving correction quality and production efficiency.

2. the present invention is by adopting the working roll that be made up of the circular arc of two sections of different curvature, adapt, and each working roll can move left and right on roll shaft, improves the adaptability of equipment for straightening and aligns efficiency with by the width of composite plate aligned.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present invention;

Fig. 2 is the A direction view in Fig. 1;

Fig. 3 is the B direction view in Fig. 1;

In figure: I-front straightener; II-rear straightener; III-joining rails; 1-front straightening machine frame: 2-rear straightening machine frame; Straightener roll on 3-front straightener; Lower smoothing roll about 4,4 ＇-front straightener; 5,5 ＇-rear straightener left and right upper straightening roll; Smoothing roll under 6-rear straightener; 7,7 ＇-front straightener left and right screwdown gear; 8,8 ＇-rear straightener left and right screwdown gear; 9-composite plate; K-composite plate moving direction.

Embodiment:

Before aligning, first according to the position of the width adjusting smoothing roll of composite plate, drafts is regulated according to the thickness of composite plate, width and material, then start straightener to align, as shown in Figure 2,3, front straightener I makes to be bent downwardly in the middle part of composite plate, and rear straightener II makes to be bent upwards in the middle part of composite plate, reaches the object eliminating residual stress in composite plate.

Claims

1. eliminate the straightener of composite plate residual stress for one kind, it includes front straightener (I), rear straightener (II), front and back straightener (I, II) joining rails (III) between and the PWTN driving front and back straightener to operate are unified and are regulated the screwdown gear of drafts, it is characterized in that: the working roll arrangement mode of front straightener (I) is that a upper straightening roll (3) is arranged on roll shaft, centre position in front straightening machine frame (1), the lower smoothing roll (4 in left and right, 4 ＇) be arranged on respectively on lower roller shaft, on position, front straightening machine frame (1) the interior left and right sides, the working roll arrangement mode of rear straightener (II) is that left and right upper straightening roll (5,5 ＇) is arranged on roll shaft respectively, on position, rear straightening machine frame (2) the interior left and right sides, lower smoothing roll (6) is arranged on lower roller shaft, on centre position in rear straightening machine frame (2), before and after smoothing roll on straightener can make left and right adjusting on roll shaft, the roll surface of all smoothing rolls by with the composite plate flexural deformation of different in width after the circular arc of multistage different curvature that adapts of plate face shape form.
