The pre-load plate fixing block 4 is slidably fitted with an upper mold guide column 6 inside, and a shaft sleeve 7 is installed at one end of the upper mold guide column 6. The upper mold spring 5 is provided on the outer sleeve of the upper mold guide column 6, and one end of the upper mold guide column 6 is connected to the upper pre-load plate 3.

[0028] Through the above technical solution, by setting up a four-column hydraulic press 22, the upper mold fixing plate 1 can be driven to descend. When the upper mold fixing plate 1 descends, the upper mold plate 2 can be driven to descend. When the upper mold plate 2 descends, the pre-load plate fixing block 4 can be driven to descend. When the pre-load plate fixing block 4 descends, the upper pre-load plate 3 can be driven to move through the upper mold guide column 6. At this time, the upper pre-load plate 3 can bend the wire mesh on the lower mold structure 24, and then the upper mold spring 5 elastically buffers the upper pre-load plate 3, so that the shaft sleeve 7 can limit the upper mold guide column 6 to prevent the upper mold guide column 6 from falling.

[0029] like Figures 1-8 As shown, according to the wire mesh bending processing device of the embodiment of the present invention, the lower mold structure 24 includes a lower mold fixing plate 8, a lower mold outer frame 9 is connected above the lower mold fixing plate 8, a buffer plate fixing block 11 is installed inside the lower mold outer frame 9, a lower mold guide column 13 is slid inside the buffer plate fixing block 11, a lower mold spring 12 is sleeved on the outer periphery of the lower mold guide column 13, one end of the lower mold guide column 13 is connected to the lower mold buffer plate 10, the outer periphery of the lower mold fixing plate 8 is connected to the discharge plate 15, the outer periphery of the discharge plate 15 is connected to the discharge block 14, and the discharge plate 15 is connected to the four-column hydraulic press 22 through the discharge pillar 16.

When the upper mold fixing plate 1 descends, it can drive the upper mold plate 2 to descend. When the upper mold plate 2 descends, it can drive the pre-load plate fixing block 4 to descend. When the pre-load plate fixing block 4 descends, it can drive the upper pre-load plate 3 to move through the upper mold guide column 6. At this time, the upper pre-load plate 3 can bend the wire mesh on the lower mold structure 24, and then the upper mold spring 5 elastically buffers the upper pre-load plate 3, so that the shaft sleeve 7 can limit the upper mold guide column 6 to prevent the upper mold guide column 6 from falling.

[0035] By providing the lower die fixing plate 8, it is convenient to fix the lower die outer frame 9, and the wire mesh is placed on the discharge plate 15.

When the rotating handwheel 21 rotates, the threaded fixing rod 19 can be driven to rotate and move in the fixed mounting frame 18. Then, the threaded fixing rod 19 drives the fixing seat 20 to rotate and move, thereby fixing the four-column hydraulic press 22.
