Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Referring to fig. 1-4, the present embodiment provides a metal plate pressure difference mold, which includes a pressure difference upper mold 1 and a pressure difference lower mold 2, wherein the pressure difference upper mold 1 and the pressure difference lower mold 2 may be disposed in a horizontal alignment manner or a vertical alignment manner.

Mould 1's tip is provided with one and is the kicking block of a certain angle on traditional pressure differential, and traditional pressure differential lower mould 2's tip is provided with one and kicking block assorted recess, and the both sides of bending are kept away from along opposite direction parallel to the panel of satisfying the requirement of bending, consequently adopt traditional pressure differential to go up mould 1 and pressure differential lower mould 2 and need bend panel twice, can't realize once only bending panel, extravagant man-hour, and difficult in order to promote production efficiency.

For some special-requirement plates, for example, the height of the bent plate needs to be below 5mm, and the use requirement can be met, and the height of the plate produced by using the traditional differential pressure upper die 1 and the differential pressure lower die 2 is 5mm at the lowest, so that the use requirement cannot be met.

The bottom of the pressure difference upper die 1 is provided with a bending ejector block 3, the top of the pressure difference lower die 2 is provided with a bending groove 4 matched with the bending ejector block 3, the bending ejector block 3 and the bending groove 4 extrude the plate, the plate can be bent along the directions of the bending ejector block 3 and the bending groove 4, and the plate can be bent.

In addition, the matched use of the bending jacking block 3 and the bending groove 4 can eliminate the influence of the rebound rate on the occlusion angle between the pressure difference upper die 1 and the pressure difference lower die 2 in the metal plate forming process.

Bending top block 3 comprises A recess 31 and B top block 32, the contained angle that A recess 31 and B top block 32 just are between the side is 120, one side that A recess 31 was kept away from to B top block 32 is parallel with one side that A recess 31 is close to B top block 32, two 120 contained angles, can make the both ends of the panel after bending parallel to each other, and 120 contained angle can also make panel when bending in the hand, with bending top block 3 and the relative motion between the 4 contact surfaces of bending recess smooth and easy more, can also make the department of bending of panel fuller simultaneously.

The bending groove 4 is composed of an A top block 41 and a B groove 42, the A top block 41 is matched with the A groove 31, and the B groove 42 is matched with the B top block 32.

Bending the kicking block 3 and bending the structure that recess 4 is the sawtooth pattern, can realize once only bending to panel, avoid the secondary operation to panel, because traditional mould is when carrying out the operation of bending to panel, divide twice to go on, cause the fixed of panel when secondary molding and the trouble that the point is all comparatively looked for, cause the height of panel to exceed 5mm more, through one shot forming, can make the height difference of panel shaping back low to 3 mm.

Meanwhile, the plate can be formed at one time, so that more processes can be omitted when the plate is bent, the time for secondary forming can be omitted, and the bending efficiency of the plate is improved.

The a groove 31 and the B top block 32 are provided integrally with the differential pressure upper die 1, and the a top block 41 and the B groove 42 are provided integrally with the differential pressure lower die 2.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
