DETAILED DESCRIPTION

[0029] See also Figures 1 to 6 In an embodiment of the present invention, a self-service gate machine arc-shaped shell automatic bending device includes:

[0030] A workbench 1, one side of which is fixedly provided with a positioning and conveying device 2 for conveying a plate-shaped shell, and the positioning and conveying device 2 is a double-belt conveying device with adjustable span, which is used for conveying and positioning shells of different specifications;

[0031] A supply assembly installed inside the workbench 1; and

[0032] A bending mechanism 3, which is arranged on the workbench 1, and the supply assembly can provide the shell to be bent to the bending mechanism 3 from bottom to top;

[0033] That is, the positioning and conveying device 2 positions and conveys the shell to be processed to the supply assembly. After the shell is fixed in the supply assembly, the supply assembly then transports the shell from bottom to top to the bending mechanism 3, and the bending mechanism 3 presses down the position of the shell to be processed to form it.

[0034] As a preferred embodiment, a bottom mold is provided in the supply assembly, and the bottom mold matches the part of the shell to be bent, and the bending mechanism 3 can drive the shell to be bent toward the arc portion of the bottom mold, which is beneficial to the forming of the arc bending and chamfering of the shell.

[0035] As a preferred embodiment, a positioning device is also provided in the supply assembly, which is used for multi-point positioning of the shell and the base mold. That is to say, the positioning device can position the shell during the molding process of the shell by the bending mechanism 3 to prevent the bending position of the shell from shifting during the molding process, thereby causing misalignment of the shell molding size or relative errors, which may easily cause size mismatch in the subsequent processing of the autonomous gate.

[0036] See also Figure 2 In this embodiment, the bending mechanism 3 includes a bending assembly 33 arranged on the workbench 1, and the bending assembly 33 is two groups symmetrically arranged. The bending assembly 33 on one side is horizontally slidably arranged on the lateral support plate, and the bending assembly 33 is connected to the output end of the one-way push cylinder 32, and the other end of the one-way push cylinder 32 is fixed with a double-axis telescopic cylinder body 31, and the other side of the double-axis telescopic cylinder body 31 is fixed with the one-way push cylinder 32, and the output end of the one-way push cylinder 32 is connected with the bending assembly 33 on the other side horizontally slidably arranged on the lateral support plate. The double-axis telescopic cylinder body 31 can adjust the horizontal lateral position of the bending assembly 33, which is beneficial for it to bend the shells at different positions (misaligned, same position) on different sides. At the same time, the bending assembly 33 on the same side is adjusted correspondingly by the independent one-way push cylinders 32 on both sides, thereby bending the shells with different curvatures on the different sides.

[0037] See also Figure 2 , Figure 3 , Figure 4 In this embodiment, the bending component 33 includes:

[0038] A fixed seat 331 is arranged on the workbench 1 and can slide horizontally and vertically. A first connecting shaft 332 and a second connecting shaft 334 are rotatably arranged on the fixed seat 331, and the upper end of the first connecting shaft 332 is rotatably connected to the upper end of the second connecting shaft 334;

[0039] A movable top block 333, which is rotatably arranged on the upper end of the first connecting shaft 332;

[0040] The roller 337 is rotatably mounted on the coupling seat 336. The coupling seat 336 is rotatably mounted on one end of the third coupling shaft 335. The other end of the third coupling shaft 335 is rotatably connected to the first coupling shaft 332.

[0041] A forming portion 338, which is fixedly disposed with the movable top block 333;

[0042] It needs to be explained that the one-way push cylinder 32 is extended, the first connecting shaft 332 and the second connecting shaft 334 are deflected, the third connecting shaft 335, the connecting shaft seat 336 and the roller 337 move outward, and the movable top block 333 drives the forming part 338 to deflect outward in an arc-shaped trajectory, which cooperates with the positioning of the bottom mold to bend the forming part of the shell.

[0043] As a preferred embodiment, the movable top block 333 and the forming portion 338 are both in a "∩" shape or an "○" shape, and a guide groove is provided at the arc portion on the side in contact with the roller 337. On the one hand, it is beneficial for the contact and following movement of the roller 337 with the movable top block 333 and the guide groove of the forming portion 338, and on the other hand, it ensures that the forming trajectory of the third connecting shaft 335 is an arc, thereby also making the movement trajectory of the forming portion 338 an arc.

[0044] See also Figure 3 As a preferred embodiment, a convex strip is provided on the inner side of the forming part 338, and the convex strip is movably provided on the positioning roller 339, which is beneficial to the sliding of the forming part 338 on the positioning roller 339, and is convenient for the positioning of the forming part 338 and the limiting of the arc motion.

[0045] See also Figure 1 As a preferred embodiment, the bending mechanism 3 is composed of two groups arranged front and back, which can be used for bending and forming both sides of the shell.

[0046] As a preferred embodiment, the two sets of the bending mechanisms 3 are connected by a connecting seat 34 which is detachable at both ends and rotatably arranged on the positioning rollers 339 on both sides, and the connecting seat 34 is a passively retractable seat body;

[0047] It should be explained that when the bending assembly 33 processes the shell body with integral arc bending on the same side, only the two forming parts 338 integrally bend the same side of the shell body, and there is a certain stress difference in the middle part of the shell body, which causes the bending degree of the contact part of the forming part 338 to reach the standard, and the corresponding middle area molding will be convex within a certain range compared to the position after molding, and the shell body will have an uneven surface. Then, by adding the connecting seat 34, the occurrence of the above situation can be effectively reduced;

[0048] It should be noted that when the forming portion 338 moves in an arc shape, the forming portion 338 can slide relatively on the positioning roller 339 to ensure that the trajectory of the forming portion 338 is not restricted, and the connecting seat 34 is a forming part, which is mostly made of a material with a relatively high hardness, so its rotation amplitude is relatively small. During the deflection process of the forming portion 338, the connecting seat 34 will generate a certain reaction force to limit its deflection. The rotation of the positioning roller 339 on the connecting seat 34 can effectively reduce the additional deflection force of the third connecting shaft 335, that is, reduce the relative force required for the extension of the one-way push cylinder 32;

[0049] That is, during the molding process of the shell only on the same side (such as Figure 5 shown):

[0050] When the shell on the same side is integrally bent, after the connecting seat 34 is installed between the forming parts 338 on both sides, the forming part 338 presses down the shell as a whole and bends it. When the straight-line shell is bent and the oblique-line shell is bent, the corresponding straight-line bottom mold and the bottom mold with a certain angle are matched, so that the forming part 338 and the connecting seat 34 are collinear and press down the shell;

[0051] When bending a shell with the same curvature in the same side partition, first adjust the horizontal longitudinal position of the fixing seat 331 so that the positions of the two forming parts 338 correspond to the bending part of the shell, and then adjust the elongation of the one-way push cylinders 32 on both sides to be the same, so that the forming parts 338 press down the shell to form;

[0052] When bending a shell with different curvatures in the same side partition, first adjust the horizontal longitudinal position of the fixing seat 331 so that the positions of the two forming parts 338 correspond to the bending part of the shell, and then adjust the different elongation amounts of the one-way push cylinders 32 on both sides, so that the forming parts 338 press down the shell to form;

[0053] In the process of molding only one side of the shell (such as Figure 6 shown):

[0054] When bending the shell at the same position on the opposite sides, the same extension amount of the double-axis telescopic cylinder 31 is adjusted, and the forming part 338 corresponds to the part of the shell to be formed, and the same or different extension amounts of the one-way push cylinders 32 on both sides are adjusted, and the forming part 338 presses the shell downward to form;

[0055] When bending the shell at different positions on different sides, the different elongations of the double-axis telescopic cylinder 31 are adjusted, and the forming part 338 corresponds to the part of the shell to be formed, and the same or different elongations of the one-way push cylinders 32 on both sides are adjusted, and the forming part 338 presses the shell downward to form;

[0056] When the same side and the opposite side of the shell need to be formed, the above processes can be selected in pairs or in combination according to the needs, so as to meet the needs of arc bending at different positions and with different curvatures of the shell.

[0057] During specific implementation, the positioning and conveying device 2 positions and conveys the shell to be processed to the supply component. After the positioning device fixes the shell and the bottom mold through multi-point positioning, the supply component transports the shell from bottom to top to the bending mechanism 3. After the horizontal position of the fixed seat 331 is adjusted by the double-axis telescopic cylinder body 31 and its horizontal longitudinal position is adjusted accordingly, the one-way push cylinder 32 is started, and the roller 337 moves outward so that the molding part cooperates with the bottom mold to press down the position of the shell to be processed.

[0058] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
