DETAILED DESCRIPTION

[0021] The specific embodiments of the utility model are further explained in detail by the description of the embodiments by comparing with the drawings, the purpose is to help the technical personnel in the field to have more complete, accurate and in-depth understanding to the inventive concept and technical scheme of the utility model, and help its implementation.

[0022] As Figures 1 to 4As shown, the die strip adjusting structure includes an upper die strip 1, one end of the upper die strip 1 is connected with a mounting shaft 2, the mounting shaft 2 is sleeved with a first single module 3 and a second single module 4, and an end of the mounting shaft 2 is provided with a third single module 5. Through the sequential assembly of the upper die strip 1, the first single module 3, the second single module 4 and the third single module 5, the die strip can form four lengths, the applicability is improved, the bending operation of plate pieces of different sizes is realized, and thus the production requirements are met. Each single module is controlled by a cylinder, and the interval between adjacent single modules can be controlled to form a space for avoiding the side edge flanging of the plate piece.

[0023] As shown in Figures 1 to 4 , one side of the upper die strip 1 is provided with a first cylinder 6 and a second cylinder 7, the upper die strip 1 is provided with a first connecting plate 14, the first cylinder 6 is fixedly connected to the first connecting plate 14, the piston rod of the first cylinder 6 is fixedly connected with a first push plate 9 of the first single module 3, the piston rod of the second cylinder 7 is fixedly connected with a second push plate 10 of the first single module 3, and the second cylinder 7 is fixedly connected with the second single module 4. The first cylinder 6 is fixedly connected with the upper die strip 1, drives the first push plate 9 to drive the first single module 3 to move along the mounting shaft 2, the piston rod of the second cylinder 7 is connected with the first single module 3 through the second push plate 10, and the second cylinder 7 moves its cylinder body under the reaction force of the piston rod to drive the second single module 4 to move along the mounting shaft 2. The movement of the above two cylinders can control the upper die strip 1 to form three lengths.

[0024] As shown in Figure 1 , the third single module 5 is fixedly connected with a second connecting plate 15, and the second connecting plate 15 is connected with a third cylinder 8. The cylinder body of the third cylinder 8 is fixed on the frame of the bending machine, and the third single module 5 is driven to move by pushing the second connecting plate 15, and at the same time, the mounting shaft 2 is inserted into the upper die strip 1 during the movement of the third single module 5. After the third single module 5 is assembled, the upper die strip 1 is at the maximum length.

[0025] As shown in Figure 2 and Figure 3 , the bottom of the upper die strip 1 is provided with an avoiding groove. The avoiding groove can realize the stamping and bending avoidance of the side edge flanging structure of the plate piece, and the side edge flanging of the other side of the plate piece can form a gap by adjusting the position of the single module, so as to achieve the avoidance effect of the side edge flanging structure of the plate piece.

[0026] As shown in Figure 2 , the mounting shafts 2 are arranged in pairs. The mounting shafts 2 are arranged in two parallel modes, and the two mounting shafts 2 ensure the accuracy of the axial movement direction of the first single module 3 and the second single module 4. Compared with the single mounting shaft 2, the two single modules can be prevented from rotating.

[0027] As shown in Figure 2 and Figure 3As shown, the avoidance groove includes a first avoidance groove 11 and a second avoidance groove 12, and the first avoidance groove 11 and the end of the first single module 3 are both in a stepped structure. The two avoidance grooves can simultaneously avoid the flanging on both sides of the punched plate, and the first avoidance groove 11 and the end of the first single module 3 are designed in a stepped structure, thereby forming two avoidance spaces with different heights to adapt to the situation that the flanging heights on different plates are different, and improve the applicability of the die strip. The main body of the first single module 3 is consistent with the cross-sectional size of the upper die strip 1 except that the end thereof is in a stepped structure, the cross-sectional size of the second single module 4 and the third single module 5 is consistent, and the bottom surfaces of the two are coplanar with the upper die strip 1, so as to ensure that the bending force is uniform.

[0028] As shown in Figure 1 The upper die strip 1 is uniformly provided with mounting bolts 13 on the top and the side. The plurality of mounting bolts 13 facilitate the stable fixation of the upper die strip 1 on the rack, and the mounting bolts 13 on the top of the upper die strip 1 are located in the waist-shaped hole, thereby facilitating the adjustment of a certain distance during the installation of the upper die strip 1.

[0029] As shown in Figure 2 The first connecting plate 14 and the second connecting plate 15 are both in an L-shaped structure. The L-shaped connecting plate is beneficial to ensure that the first air cylinder 6 and the second air cylinder 7 are stable and aligned after installation.

[0030] The die strip adjusting structure has a simple structure, and the assembly of the single module and the upper die strip 1 is controlled by the movement of the air cylinder, so that the upper die strip 1 can be assembled to have various lengths, thereby meeting the needs of bending different sizes of plates, saving the die strip switching process, improving the production efficiency, and the upper die strip 1 is designed with an avoidance groove, thereby avoiding the flanging structure on the side of the plate, and meeting the production needs.

[0031] The above has been described by way of example in combination with the drawings. Apparently, the specific implementation of the present application is not limited to the above manner. As long as various non-essential improvements are made by adopting the method concept and technical scheme of the present application, or the above concept and technical scheme of the present application are directly applied to other occasions without improvement, they are all within the protection scope of the present application.
