Abstract

The invention discloses an air deflector outer plate forming process, and belongs to the technical field of air deflectors. The air deflector outer plate forming process comprises the following steps: a pre-bending step: pre-bending edges of two ends of an outer plate to a set radius of curvature, and carrying out check and calibration by using a sample plate; horizontally arranging one end of the outer plate and sending the outer plate into a plate rolling machine, aligning the end edge with the center lines of an upper shaft roll and of a lower shaft roll, enabling the inward flange of the end to be close to a sliding block, elevating the lower shaft roll to tightly clamp the outer plate, and inclining a left roll; and lowering the side roll and the lower shaft roll until the outer plate is loose, adjusting the position of the outer plate, and aligning the first bus of the end of the outer plate with the center lines of the upper shaft roll and of the lower shaft roll. The air deflector outer plate forming process has the following advantages: 1) a press is not used for pre-bending so that the labor cost is reduced and the machine resources are fully utilized; 2) two ends of the outer plate are not rolled by adding 400-500mm margin so that the material cost is reduced; and 3) the two ends are prevented from linear segments and bending points so that the product quality is improved and the back-end process is prevented from unnecessary troubles.

Description

Kuppe outside plate moulding process

Technical field

The invention belongs to deflector technical field, be specifically related to kuppe outside plate moulding process.

Background technology

In prior art, to deflector outside plate moulding process, see according to forcing press pre-bending outside plate two ends, though energy Obtain required radius of curvature, but cost is relatively big, and the time taking forcing press is longer, has a strong impact on rear road The connecting of operation；Roll up curved outside plate two ends according to veneer reeling machine, produce straightway or have obvious bending point, no Fairing, this is owing to the structure of veneer reeling machine is caused, and can have a strong impact on the quality of product.

Summary of the invention

Goal of the invention: it is an object of the invention to provide kuppe outside plate moulding process, overcome of the prior art Shortcoming, it is ensured that the line style rolled out is consistent with requirement.

Technical scheme: for achieving the above object, the present invention adopts the following technical scheme that

Kuppe outside plate moulding process, including pre-bending step: outside plate edges at two ends is bent to the curvature half set the most in advance Footpath, with model inspection calibration；Specifically one end of outside plate is kept flat feeding veneer reeling machine, and end edge is directed at upper shaft Roller and the centrage of lower roller, inward flange is close to slide block, raises lower roller clamping outside plate, tilted left side roller；Fall Low left roller and lower roller loosen to outside plate, adjust outer Board position, and the first bus of outside plate end is directed at upper shaft Roller and the centrage of lower roller.

The a length of 400-500mm of pre-bending in described pre-bending step.

It was cleanup step before described pre-bending step, outside plate surrounding is removed clean because of the residue that cutting stays, And clean the surface of outside plate.

It is centering step after described pre-bending step, the outside plate that pre-bending is good, sends into veneer reeling machine, and outside plate The slide block of inward flange alignment lower roller.

It is to roll up curved step after described centering step, when rolling up curved taper seat, make in beaming roller and lower roller Heart line is adjusted to obliquity, makes roller centrage overlap with the bus of fan-shaped outside plate, keeps the centrage of roller Substantially parallel with outside plate bus.

Being that calibration steps checked by model after the described curved step of volume, if not up to adjusting parameter, repeating pre-bending step Suddenly, until the line style rolled out is consistent with requirement.

Beneficial effect: compared with prior art, the present invention possesses advantages below:

1) avoid using forcing press pre-bending, reduce cost of labor, and machine resources is fully used；

2) outside plate two ends need not add 400-500mm surplus and roll, thus reduce material cost；

3) two ends avoid straightway and bending point, improve the quality of product, also avoid not for later process Necessary trouble.

Detailed description of the invention

Below in conjunction with the accompanying drawings and detailed description of the invention, it is further elucidated with the present invention.

In prior art, to deflector outside plate moulding process, as it is shown in figure 1, at CD (400-500mm) Being easily generated straightway and obvious bending point in region, this is owing to the structure of veneer reeling machine is caused, can be serious Affect the quality of product.If add 400-500mm surplus at outside plate two ends, as in figure 2 it is shown, in prior art It is directly A section to be cut, retains B section and C section avoids straightway and obvious bending point, but material becomes This can be greatly improved.

Kuppe outside plate moulding process, comprises the steps:

1) cleaning

Outside plate 1 surrounding is removed clean because of the residue that cutting stays, and cleans the surface of outside plate 1；

2) pre-bending

As shown in Fig. 3 (a), outside plate 1 edges at two ends is first bent to satisfactory radius of curvature in advance, uses model Inspection, specifically keeps flat feeding veneer reeling machine by one end of outside plate 1, and by upper for end edge alignment beaming roller 4 and lower roller The centrage of 3, inward flange is close to slide block, raises lower roller 3 and clamps outside plate 1, as shown in Figure 4, tilts a left side Side roller 2, and slowly it is raised to certain position, can't excessively raise, it is to avoid molding is excessive；On the left of reduction Roller 2 and lower roller 3 to outside plate 1 loosen, and adjust outside plate 1 position, are directed at by the first bus of outside plate 1 end Upper beaming roller 4 and the centrage of lower roller 3, repetitive operation step 1)-2), pre-bending length 400-500mm；

3) centering

Outside plate 1 good for pre-bending, send into veneer reeling machine, and the slide block of outside plate 1 inward flange alignment lower roller 3；

4) roll up curved

When rolling up curved taper seat, beaming roller 4 to be made to be adjusted to obliquity, such as Fig. 3 with the centrage of lower roller 3 Shown in (b), make roller centrage overlap with the bus of fan-shaped outside plate, keep centrage and the outside plate 1 of roller Bus is substantially parallel；

5) inspection

Go to check line style with model, if not up to, adjust parameter, until the line style rolled out is consistent with requirement.
