The first stamper 1 and the second stamper 2 may be arranged vertically up and down, or horizontally left and right, or may be arranged obliquely in an oblique direction.
During processing, the workpiece bending die is matched with a press machine, the press machine can push the first press die 1 to move relative to the second press die 2, and can also push the second press die 2 to move relative to the first press die 1, and of course, two press machines can also be adopted, and the first press die 1 and the second press die 2 can be pushed to move in opposite directions.

Specifically, the movable plate 23 can be connected with other parts of the open cavity through bolts, and when the open cavity needs to be opened, the movable plate 23 can be detached by unscrewing the bolts, so that one side of the open cavity is opened, and the machined workpiece 10 is taken out from the side surface of the open cavity.
In another alternative embodiment of the workpiece bending die provided by the present invention, for the purpose of enabling one side of the open cavity to be opened, the open cavity includes a reversible movable plate 23 provided at a side surface to enable one side of the open cavity to be opened by turning the movable plate 23 after the processing of the workpiece 10 is completed.
Specifically, one side of the open cavity is opened by turning the movable plate 23 to take out the processed work 10 from the side of the open cavity. The movable plate 23 is opened through the overturning action, so that the movable plate 23 does not need to be frequently disassembled, and after the workpiece 10 is taken out, the workpiece can be reset through reversely overturning the movable plate 23, and the operation is simple, thereby being beneficial to improving the efficiency.
Further, the second die 2 includes an elastic mechanism for resetting the movable plate 23 after the movable plate 23 is turned over.

As shown in fig. 1, 3 and 5, the second stamper 2 includes a second stamper body 21, a fixed plate 22 and a movable plate 23, the fixed plate 22 is fixedly installed at a first side of the second stamper body 21, the movable plate 23 is movably installed at the other side of the second stamper body 21, and a groove is provided at the top of the second stamper body 21 to form an open cavity through the second stamper body 21, the fixed plate 22 and the movable plate 23.
The movable plate 23 is provided with a spring mounting plate 28, and one end of the spring 27 is connected to the movable plate 23 through the spring mounting plate 28; the other side of the second die body 21 of the second die 2 opposite to the movable plate 23 is provided with a fixed plate 22, the fixed plate 22 is also provided with a spring mounting plate 28, and the other end of the spring 27 can be connected to the fixed plate 22 through the spring mounting plate 28. Of course, the other end of the spring 27 may be connected to the other side surface of the second die body 21 as long as the return of the movable plate 23 can be achieved.
To achieve the overturning, the second die 2 includes the support 24 and the link plate 32, one end of the link plate 32 is connected to the movable plate 23, and the other end of the link plate 32 is rotatably connected to the support 24, so that the movable plate 23 is mounted on the support 24 through the link plate 32 in an overturned manner.
Specifically, the movable plate 23 may be welded to the connecting plate 32, the support 24 includes two opposite support plates with through holes, the connecting plate 32 is also provided with through holes, and the pin 25 passes through the support plates and the through holes on the connecting plate 32, so that the purpose that the connecting plate 32 can rotate around the support 24 can be achieved. Thus, by turning the movable plate 23 upward, the movable plate 23 can be moved away from the second die body 21, thereby opening one side of the open cavity.
As another improvement of the workpiece bending die provided by the present invention, the workpiece bending die includes a guide mechanism for maintaining alignment of the first die 1 and the second die 2 during relative movement of the first die 1 and the second die 2.
By providing the guide mechanism, the alignment of the first die 1 and the second die 2 can be maintained during the process of contacting the first die 1 with the second die 2 and continuing the relative movement, and uneven compression of the workpiece 10 due to dislocation can be prevented from affecting the bending effect of the workpiece.
Optionally, the guiding means comprises at least two sets of guiding means, which are arranged on both sides of the open cavity, respectively, to clamp the open cavity during the relative movement of the first stamp 1 and the second stamp 2, preventing the openable side of the open cavity from being opened due to unexpected conditions during processing. In this way, the guiding mechanism can realize a clamping effect in addition to a guiding effect, and prevent the side of the open cavity, which can be opened, from loosening or opening due to accidents, so that bulging of the workpiece 10 during bending can be avoided, and the workpiece 10 can be limited in the open cavity.
Alternatively, the guide mechanism includes a guide block 14 provided on one of the first die 1 and the second die 2 and a guide groove provided on the other of the first die 1 and the second die 2 to guide the relative movement of the first die 1 and the second die 2 by the cooperation of the guide block 14 and the guide groove. When the first die 1 is in contact with the second die 2, the guide block 14 is inserted into the guide groove, and the relative movement of the first die 1 and the second die 2 can be made more accurate by the restriction and the guide of the guide groove, thereby preventing the dislocation.
Specifically, the guide block 14 may be mounted on the mounting plate 13, and the mounting plate 13 is mounted on the first die body 12.
Alternatively, the number of the guide blocks 14 is 4, and two sides of the first die body 12 are arranged one on each side to limit the first die 1 from the front-rear direction and the left-right direction.
Accordingly, the number of guide grooves may be the same as the number of guide blocks 14, for example, one guide block 14 is inserted into one guide groove, so that more precise control can be achieved.
Of course, the number of the guide grooves may be different from that of the guide blocks 14, and in the embodiment shown in fig. 5, two mounting blocks 26 are provided on the side of the movable plate 23, one protruding strip 261 is provided on each mounting block 26, the guide grooves are formed between the two protruding strips 261 provided on the two mounting blocks 26, and the two guide blocks 14 are respectively limited by the two protruding strips 261. Alternatively, the distance between the two guide blocks 14 is substantially the same as the distance between the two raised strips 261, so that the guide effect can be achieved by the guide grooves formed between the two raised strips 261 cooperating with the guide blocks 14.
Wherein, a rib plate 15 can be arranged between the two guide blocks 14 to strengthen the stability of the guide blocks 14. In addition, due to the presence of the mounting block 26, an L-shaped notch may be provided in the guide block 14 to prevent interference with the mounting block 26.
Of course, the guide mechanism may take other forms than the above, as long as the guide function can be achieved.
Alternatively, the distance between the top surface of the fixed plate 22 and the top surface of the second die body 21 and the distance between the top surface of the movable plate 23 and the top surface of the second die body 21 are not smaller than the height of the work 10, i.e., the height of the fixed plate 22 and the movable plate 23 above at least one work 10 of the second die body 21, which has the advantage of restricting bulging of the work 10 during bending of the work 10 and preventing wrinkling of the work 10.
The height of the workpiece 10 refers to the groove height for groove-shaped workpieces, the height of the workpiece 10 refers to the thickness of a plate-shaped workpiece, and the height of the workpiece 10 is adaptively adjusted for workpieces of other structural forms, so that the workpiece can mainly play a role in limiting bulging and wrinkling of the workpiece.
