The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides a quick die changing device for a bending machine, such as Figure 1-4 As shown, a quick mold changing device for a bending machine comprises a bending machine platform 1, a casing 5 and a first limit seat 7. The top of the bending machine platform 1 is connected to a second limit seat 9. A moving structure 3 is arranged on one side of the bending machine platform 1, and a base 2 is arranged on the bottom end of the moving structure 3. A connecting rod 4 is arranged on the top of the moving structure 3, and the top of the connecting rod 4 is connected to a casing 5. A pushing mechanism 6 is arranged inside the casing 5. The top of the casing 5 is connected to a top plate 8, and the top of the top plate 8 is connected to the first limit seat 7. The interiors of both sides of the second limit seat 9 are threadedly connected to fixing rods 11, and one side of the fixing rod 11 is connected to a clamping plate 10. The pushing mechanism 6 comprises a screw 601, a casing block 602, a partition 603, a stepping motor 604, a fixing plate 605, a push plate 606 and a rubber pad 607. The partition 603 is connected to the inner wall of the casing 5, and a stepping motor 604 is installed on one side of the partition 603.

[0023] The working principle of the quick mold changing device of the bending machine is: the device is supported and placed by the base 2, and powered by an external power supply. First, multiple groups of lower molds required for tool processing are placed in multiple groups of first limit seats 7 respectively. When the bending notch of the lower mold in the second limit seat 9 needs to be replaced, the fixing rod 11 is rotated in the opposite direction to engage with the second limit seat 9 threadedly to drive the clamping plate 10 to leave the surface of the lower mold, and then the sleeve 5 on the connecting rod 4 is driven by the moving structure 3 to move back and forth, so that the first limit seat 7 with the corresponding lower mold is aligned with the second limit seat 9 and stopped, and then the pushing mechanism 6 is started to directly push the lower mold in the first limit seat 7 gradually into the second limit seat 9, and the existing lower mold in the second limit seat 9 is pushed out from the right opening, so that it falls into the collecting device and stops, thereby achieving the effect of quick mold change and reducing manual operation of the staff.

[0024] It should be noted that, since the existing quick mold changing device of the bending machine generally requires personnel to push the required lower mold from the first limit seat 7 into the second limit seat 9, this operation increases the workload of the staff. Therefore, in order to solve the problem that the existing quick mold changing device of the bending machine cannot be pushed automatically, this solution adds a pushing mechanism 6 to facilitate the automatic pushing of the required lower mold in the corresponding first limit seat 7 into the second limit seat 9.

[0025] In a further embodiment, Figure 1 and Figure 4 As shown, one side of the stepper motor 604 is connected to a screw rod 601, and the outer side of the screw rod 601 is threadedly connected to a sleeve block 602, the top of the sleeve block 602 is connected to a fixed plate 605, and one side of the fixed plate 605 is connected to a push plate 606, one side of the push plate 606 is provided with a rubber pad 607, the bottom of the base 2 is in contact with the ground, the fixed plate 605 passes through the top plate 8 and enters the first limit seat 7 to be connected to the push plate 606, the inner wall of the second limit seat 9 is provided with an internal thread that matches the external thread on the fixed rod 11, and the number of push plates 606 is equal to the number of the first limit seat 7.

[0026] In this embodiment, when it is necessary to push the corresponding bending groove of the lower mold in the first limit seat 7 into the second limit seat 9, the stepper motor 604 on the starting partition 603 drives the screw rod 601 to rotate forward, and then the sleeve block 602 engages with the thread on the rotating screw rod 601 to drive the fixed plate 605 to gradually slide to the right along the top plate 8 and the inner wall of the first limit seat 7, and then the push plate 606 gradually moves to the right with the fixed plate 605 to contact the new lower mold in the corresponding first limit seat 7, and pushes the new lower mold to gradually move to the right and completely enter the second limit seat 9 to push out the original lower mold in the second limit seat 9 and stop, thereby achieving the effect of automatic pushing, reducing manual operation of the staff, and the setting of the elastic rubber pad 607 can prevent the new lower mold in the first limit seat 7 from being worn on the side that contacts the push plate 606.

[0027] In a further embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the moving structure 3 includes a support frame 301, a screw 302, a moving block 303, a slide rail 304, a slider 305, a connecting platform 306 and a hand wheel 307. The support frame 301 is connected to one side of the bending machine 1. The support frame 301 is connected to the inside of the support frame 301, and the outer side of the screw 302 is threadedly connected to the moving block 303. One end of the screw 302 is connected to the hand wheel 307. One side of the moving block 303 is connected to the connecting platform 306, and the bottom end of the connecting platform 306 is connected to the slider 305. The outer side of the slider 305 is sleeved with a slide rail 304, and the bottom of the slide rail 304 is connected to the top of the base 2. The connecting platform 306 forms a sliding structure with the slide rail 304 through the slider 305. The end of the screw 302 away from the hand wheel 307 is connected to the bearing in the support frame 301, and the sliders 305 are symmetrically distributed at the bottom end of the connecting platform 306.

[0028] In this embodiment, when it is necessary to move and align the first limit seat 7 and the second limit seat 9 equipped with the corresponding new lower mold, the screw 302 in the support frame 301 can be rotated forward or reversely through the hand wheel 307, so that the moving block 303 is threadedly engaged with the screw 302 rotating forward or reversely to drive the connecting platform 306 to gradually slide forward or backward along the inner wall of the slide rail 304 through the slider 305. At the same time, the connecting rod 4 drives the sleeve shell 5 to move forward and backward with the movement of the connecting platform 306, and then the top plate 8 drives multiple groups of first limit seats 7 to move forward and backward to adjust the position, so as to facilitate the alignment of the first limit seat 7 and the second limit seat 9 equipped with the corresponding new lower mold, thereby facilitating subsequent mold changing operations.
