[0002] Die steel is a type of steel used to manufacture molds such as cold stamping dies, hot forging dies, and die casting molds. During the processing of die steel, it needs to be bent into different sizes according to production requirements. Traditional die steel bending processing equipment requires changing upper and lower dies of different sizes according to production needs, which leads to low production efficiency and increased production costs. Moreover, it cannot ensure that the die steel placed on the lower die is in the center position, which can easily lead to inaccurate bending.

[0003] To address the aforementioned issues, there is an urgent need for innovative design based on the existing mold steel bending processing equipment. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 This utility model provides a technical solution: an adjustable mold steel bending processing device, including a base 1, a support block 2 fixed on the top side of the base 1, a first adjustment mechanism provided on the support block 2, an L-shaped frame 11 fixed at the center of the rear side of the top of the base 1, a cylinder 12 fixed through the top of the L-shaped frame 11, the lower end of the cylinder 12 fixedly connected to the center of the top of the movable frame 13, a second guide rod 14 fixed on both sides of the top of the movable frame 13, the upper end of the second guide rod 14 penetrating through the top of the L-shaped frame 11, and the second guide rod 14 slidingly connected to the L-shaped frame 11, and a second adjustment mechanism provided inside the movable frame 13.

[0017] The first adjustment mechanism includes a first rotating shaft 3. The first rotating shaft 3 is rotatably mounted inside the support block 2 via bearings. A lead screw 4 is threaded inside the first rotating shaft 3. The end of the lead screw 4 passes through the interior of the first rotating shaft 3 and is fixedly connected to the center of one side of the lower mold 5. The bottom of the lower mold 5 is in contact with the top of the base 1. A first gear 7 is fixed to the other end of the first rotating shaft 3. A second rotating shaft 8 is rotatably mounted inside the base 1 via bearings. A second gear 9 is fixed to both ends of the second rotating shaft 8 outside the base 1. The top of the second gear 9 meshes with the bottom of the first gear 7. The center of one side of the second gear 9 is fixedly connected to the output end of the first servo motor 10. The outer wall of the first servo motor 10 is fixed to one side of the base 1 via a mounting plate. A first guide rod 6 is fixed to one end of one side of the lower mold 5. The end of the first guide rod 6 passes through the interior of the support block 2 and is slidably connected to the support block 2.

[0018] The second adjustment mechanism includes a third rotating shaft 15. The third rotating shaft 15 is rotatably mounted inside the movable frame 13 via bearings. An upper mold 16 is threaded on the outer side of the third rotating shaft 15. A third guide rod 17 passes through the interior of the upper mold 16 below the third rotating shaft 15 and is slidably connected to the upper mold 16. The end of the third guide rod 17 is fixedly connected to the inner wall of the movable frame 13. The end of the third rotating shaft 15 is fixedly connected to the output end of the second servo motor 18. The outer wall of the second servo motor 18 is fixed to the outer wall of the movable frame 13 via a mounting plate. A horizontal pressure plate 19 is fixed on one side of the upper mold 16 below the movable frame 13.

[0019] Support block 2, first rotating shaft 3, lead screw 4, lower mold 5, first gear 7, and second gear 9 are symmetrically distributed in twos about the central axis of base 1, and first guide rod 6 is symmetrically distributed in twos about the central axis of lower mold 5. The thread directions on the two lead screws 4 are designed to be opposite. By starting the first servo motor 10 to rotate forward or reverse, the distance between the two lower molds 5 can be adjusted, thereby forming mold grooves of different sizes between the two lower molds 5 for forming mold steel bending parts of different sizes.

[0020] There are two upper molds 16 and two horizontal pressure plates 19 symmetrically distributed about the central axis of the base 1. The threads at both ends of the third rotating shaft 15 are opposite. The outer side of the upper mold 16 is in contact with the inner side of the movable frame 13. By starting the second servo motor 18 to rotate forward or backward, the two upper molds 16 can move closer to each other or move further away from each other, so as to center and position mold steel of different sizes. At the same time, the distance between the two upper molds 16 can be adjusted to stamp out mold steel bending parts of different sizes.

[0021] Working principle: When using this adjustable die steel bending processing device, the die steel is first placed on top of the two lower dies 5, and then the first servo motor 10 is started. The first servo motor 10 drives the second rotating shaft 8, the two second gears 9, the two first gears 7 and the two first rotating shafts 3 to rotate simultaneously. Since the first rotating shaft 3 and the lead screw 4 are threadedly connected, and the first guide rod 6 and the support block 2 are slidably connected, and the thread directions on the two lead screws 4 are designed to be opposite, the two lower dies 5 move closer to each other until the distance between the two lower dies 5 is slightly greater than the distance between the outer sides of the die steel bending parts.

[0022] Next, the second servo motor 18 is started, driving the third rotating shaft 15 to rotate. Since the threads at both ends of the third rotating shaft 15 are in opposite directions, and the third rotating shaft 15 is threadedly connected to the upper mold 16, and the upper mold 16 is slidably connected to the third guide rod 17, the two upper molds 16 move away from each other until the distance between them is greater than the length of the mold steel. At this point, the cylinder 12 is started, driving the upper mold 16 downwards until the bottom of the upper mold 16 contacts the top of the lower mold 5. Then, the second servo motor 18 is started to rotate in the opposite direction, causing the two upper molds 16 to move closer to each other. Under the action of the two upper molds 16, the mold steel is positioned centered between the lower molds 5.

[0023] The cylinder 12 is started to drive the two upper molds 16 to move upward and reset. Then the second servo motor 18 is started to make the two upper molds 16 move closer to each other until the maximum distance between the two upper molds 16 is slightly less than the distance between the inner sides of the mold steel bending part. Then the cylinder 12 is started to drive the two upper molds 16 to move downward to bend the mold steel. The horizontal pressure plate 19 presses the two ends of the mold steel onto the top of the lower mold 5, so that the mold steel is bent into shape.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
