DETAILED DESCRIPTION OF THE INVENTION

(7) The present invention is further described below with reference to the accompanying drawings:

Embodiment 1

(8) As shown in FIG. 1 to FIG. 5, a die adjustment mechanism comprises a base 1, where the base 1 is provided with a die 2 that can apply pressure on the workpiece; the die 2 includes multiple modules 21 arranged sequentially and capable of sliding laterally relative to the base 1; the base 1 is further provided with a slide rest 3/slide rests 3 capable of sliding laterally relative to the base 1; each slide rest 3 is provided with a shifting fork 4 which can be clamped with a module 21 or can be clamped between two adjacent modules 21; the slide rest 3 is provided with a drive component 5 capable of driving the shifting fork 4 to be clamped with the module 21 or be clamped between the two modules 21. The lateral sliding of the slide rest 3 may be driven by a ball screw or other transmission mechanisms.

(9) As shown in FIG. 1, FIG. 2, and FIG. 5, when the die 2 cooperates with the lower die table 10 to press the workpiece 20, the slide rest 3 is/the slide rests 3 are driven to slide laterally on the base 1; when the slide rest 3 slides to a required position/the slide rests 3 slide to required position correspondingly, the drive component 5 drives the shifting fork 4 to move relative to the slide rest 3 so that the shifting fork 4 is clamped with the module 21 or the shifting fork 4 is clamped between two adjacent modules 21 respectively; subsequently, the slide rest 3 is/the slide rests 3 are driven again to slide laterally relative to the base 1. During the sliding of the slide rest 3, the shifting fork 4 can apply a lateral pushing force on the module 21 of one side respectively, so as to push the module 21/modules 21 to slide relative to the base 1; therefore, multiple modules 21 can be separated, so that the required width of the die 2 can be changed, and the width of the die 2 can be freely adjusted. Therefore, the more the modules 21 pushed outward by the shifting fork 4/the shifting forks 4, the narrower the width of the die 2 composed by the left modules 21; the less the modules 21 pushed outward by the shifting fork 4/the shifting forks, the wider the die 2 composed by the left modules 21. Therefore, when the width of the workpiece 20 changes during the machining process, the width of the die 2 may be adjusted by actions of the slide rest 3/the slide rests 3 and the shifting fork 4/the shifting forks 4, so that the width of the die 2 is adapted to that of the workpiece 20 during actual machining. When the width of the die 2 is adjusted appropriately, the base 1 approaches the lower die table 10, so as to drive the die 2 to approach the lower die table 10 and perform pressing on the workpiece 20. Therefore, bending and pressing of multiple sides of a metal plate can be completed by one same machine and the production efficiency is greatly improved.

(10) As shown in FIG. 2 to FIG. 4, the shifting fork 4 and the slide rest 3 are hinged by a hinge shaft 6 respectively. Each drive component 5 includes a vertical strip hole 51 provided on the slide rest 3, the shifting fork 4 is provided with an inclined strip hole 52, a lateral pushing shaft 53 penetrates through the vertical strip hole 51 and the inclined strip hole 52, and the lateral pushing shaft 53 can slide along the vertical strip hole 51 and cooperates with the hole wall of the inclined strip hole 52 during sliding to push the shifting fork 4 to rotate relative to the slide rest 3; each slide rest 3 is provided with a pushing member 54 used to push the pushing shaft 53 to slide along the vertical strip hole 51 respectively. The pushing member 4 shown may be a cylinder, a ball screw or a hydraulic cylinder and the like.

(11) As shown in FIG. 2 to FIG. 4, during the process of driving the pushing shaft 53 by the pushing member 54, the pushing shaft 53 slides along the vertical strip hole 51; meanwhile, the pushing shaft 53 cooperates with the hole wall of the inclined strip hole 52 so as to apply a pushing force on the shifting fork 4, therefore, the shifting fork 4 rotates relative to the slide rest 3 by using the hinge shaft 6 correspondingly. So that, when the shifting fork 4 is required to move the module 21 to one side, the shifting fork 4 is rotated to be clamped with the module 21 or is rotated to a position, as shown in FIG. 3, clamped between two adjacent modules 21; when the die 2 needs to compress a workpiece 20 without adjusting the width of the die 2 by the shifting fork 4, the shifting fork 4 rotates to a position separated from the module 21/modules 21, as shown in FIG. 4. The entire structure is cleverly designed and the structure is simple.

(12) As shown in FIG. 1, each shifting fork 4 is provided with a clamping slot 7; after the shifting fork 5 rotates relative to the slide rest 3 respectively, a module 21 can be clamped into the clamping slot 7.

(13) As shown in FIG. 1 and FIG. 5, there are two slide rests 3, two shifting forks 4, and two drive components 5. Therefore, the width of the die 2 can be quickly and freely adjusted, and the production efficiency is greatly improved.

Embodiment 2

(14) As shown in FIG. 6, embodiment 1 differs from embodiment 2 in that:

(15) The shifting fork 4 is provided in an inclined manner and is connected to the slide rest 3 respectively in a slidable manner; the drive component 5 includes a drive cylinder 55 that is provided on the slide rest 3 and can drive the shifting fork 4 to slide in an inclined manner relative to the slide rest 3 to be clamped with a module 21 or clamp between two adjacent modules 21 correspondingly. When the width of the die 2 needs to be adjusted, the drive cylinder 55 drives the shifting fork 4 to slide in an inclined manner so as to be clamped with the module 21 or clamped between two adjacent modules 21, and subsequently, the slide rest 3 slides laterally. The entire structure is simple and reliable, and operates stably.
