For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0028] In one embodiment of the present invention, Figures 1 to 5 As shown, a mechanism for bending a high-strength steel plate is provided, including an upper die and a lower die, and a height adjustment mechanism, a support mechanism and a forming block 15 are provided on the lower die. The height adjustment mechanism is arranged in parallel on one side of the support mechanism and the forming block 15, and the support mechanism is arranged on one side of the forming block 15. An upper die punch 9 and a stripping mechanism are provided on the upper die. An upper die fixing block 8 is provided between the upper die and the upper die punch 9. The stripping mechanism is arranged on one side of the upper die punch 9.

[0029] The height adjustment mechanism includes a floating plate 12, a lifting driving component, a floating plate insert 11 and a rotating fixed block 13. The rotating fixed block 13 is arranged on the lower mold. One end of the floating plate 12 is rotatably connected to the rotating fixed block 13. The lifting driving component is arranged in the lower mold, and the output end of the lifting driving component passes through the lower mold and contacts the bottom surface of the other end of the floating plate 12. The floating plate insert 11 is arranged on the floating plate 12. When the upper mold and the lower mold are opened, the lifting driving component drives the floating plate 12 to move upward, so that the height of the floating plate insert 11 is higher than the height of the forming block 15.

[0030] Specifically, when the mold is opened, the floating plate 12 is rotated around the rotating fixed block 13 through the lifting driving component, so that the floating plate 12 moves upward relative to the lower mold, driving the floating plate insert 11 to lift the molded product to the robot transfer position, which is convenient for the robot to clamp, and the floating plate 12 is lifted by the lifting driving component, so that the product can be lifted to the same position each time it is molded, which is convenient for the automated production of the mold, simplifies the product picking steps, and reduces the fatigue of the staff.

[0031] Furthermore, a rotation groove is provided between the rotation fixing block 13 and the floating plate 12, and the floating plate 12 and the rotation groove are rotationally connected via a rotation shaft 14. In this embodiment, the two adjacent sets of inner walls of the rotation groove are formed at an obtuse angle, which can locate the upper limit position of the floating plate 12 and prevent the floating plate 12 from moving beyond the travel.

[0032] Furthermore, the lifting drive member includes a driving cylinder 18 and a driving block 19. The driving cylinder 18 is arranged in the lower mold, and the output end of the driving cylinder 18 is connected to the driving block 19, and the output end of the driving cylinder 18 passes through the lower mold. The driving block 19 is in conflict with the bottom surface of the floating plate 12. In this embodiment, a through hole is provided between the lower mold and the output end of the driving cylinder 18, so that the driving cylinder 18 can drive the driving block 19 to move up and down.

[0033] When the upper and lower molds are opened, the driving cylinder 18 is started, and the output end of the driving cylinder 18 drives the driving block 19 to move upward relative to the lower mold. The driving block 19 lifts one end of the floating plate 12 and the other end of the floating plate 12 rotates around the rotating shaft 14, thereby lifting one end of the floating plate 12, so that the floating plate insert 11 lifts the molded product out of the lower mold and moves it to the position for the robot to transfer.

[0034] Furthermore, the support mechanism includes a support block 16 and a wear-resistant plate 17. The support block 16 is provided on the lower die and is located on one side of the rotating fixed block 13. The wear-resistant plate 17 is provided on the side of the support block 16 close to the forming block 15. When the upper die and the lower die are closed, the support block 16 is always tightly fitted with one side of the upper die punch 9, providing a stable support force for the forming process, preventing the rebound of the product material from affecting the processing quality, and the wear-resistant plate 17 is also provided to reduce the damage to the support block 16 during the processing process and improve the service life of the support block 16.

[0035] Furthermore, the forming block 15 is provided with a first forming surface 151 and a second forming surface 152. Both the first forming surface 151 and the second forming surface 152 are inclined, and there is a first angle between the first forming surface 151 and the second forming surface 152. In the present embodiment, the first angle is an acute angle. When the upper mold and the lower mold are closed, the first forming surface 151 and the second forming surface 152 are inclinedly arranged on the surface of the forming block 15, that is, the forming becomes an inclined forming method. Under the action of the first forming surface 151, the second forming surface 152 and the first angle, the forming force is greater than the tensile strength of the product, the rebound of the product is reduced, the number of mold changes is reduced, and the mold cost is reduced.

[0036] Furthermore, the floating plate insert 11 is provided with a third molding surface 111 corresponding to the first molding surface 151 and a fourth molding surface 112 corresponding to the second molding surface 152. The third molding surface 111 and the fourth molding surface 112 are both inclined, and a second angle is formed between the third molding surface 111 and the fourth molding surface 112. In this embodiment, the third molding surface 111 and the first molding surface 151, and the fourth molding surface 112 and the second molding surface 152 correspond to each other, so that the two parts of the bending surface can be connected end to end to confirm the processing quality of the bending surface.

[0037] When the upper mold and the lower mold are closed, the third molding surface 111 and the fourth molding surface 112 are inclined on the surface of the molding block 15, that is, the molding becomes a slope molding method. Under the action of the third molding surface 111, the fourth molding surface 112 and the second angle, the molding force is greater than the tensile strength of the product, which reduces the rebound of the product, reduces the number of mold changes, and reduces the mold cost.

[0038] Furthermore, the stripping mechanism includes a stripping plate 6 and a stripping insert 7. The stripping plate 6 is arranged on the upper mold, and a spring 4 and a contour sleeve 5 are arranged between the stripping plate 6 and the upper mold. The stripping insert 7 is connected to the stripping plate 6. When the upper mold and the lower mold are opened, under the action of the spring 4, the stripping plate 6 moves downward relative to the upper mold, and the stripping plate 6 drives the stripping insert 7 to move downward and move to the extreme position of the contour sleeve 5, so that the product is stripped to avoid the product from adhering to the upper mold.

[0039] Furthermore, the upper die includes an upper support plate 1 and an upper die seat 3 from top to bottom. An upper pad 2 is provided between the upper support plate 1 and the upper die seat 3. The upper die punch 9 and the stripping mechanism are both provided on the upper die seat 3. The lower die includes a lower support plate 22 and a lower die seat 20 from bottom to top. A lower pad 21 is provided between the lower support plate 22 and the lower die seat 20. The height adjustment mechanism, the support mechanism, and the forming block 15 are all provided on the lower die seat 20.

[0040] By setting a height adjustment mechanism, when opening the mold, the floating plate 12 is rotated around the rotating fixed block 13 through the lifting driving component, so that the floating plate 12 moves upward relative to the lower mold, driving the floating plate insert 11 to lift the molded product to the robot transfer position, which is convenient for the robot to clamp, and the lifting driving component lifts the floating plate 12, so that the product after each molding can be lifted to the same position, which is convenient for the automated production of the mold, simplifies the product picking steps, and reduces the fatigue intensity of the staff.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
