[0023] In order to make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model.

[0024] In the description of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality" means two or more unless otherwise specifically defined.

[0025] Refer to Figure 1 Figure 3As shown in the figure, a continuous stamping, bending and cutting integrated device is used to process a cover. The finished product is a box body with an opening on one side, and a horizontal fixing part is provided on both sides of the opening. The device includes six consecutive stations. The blanking plate is processed by stamping, bending and cutting into multiple finished products through six consecutive stations. The blanking plate is usually a continuous coil material leveled by a leveler. A set of edge contour cutters 11 is provided on the first station 1. The edge contour cutters 11 are two respectively arranged on both sides of the blanking plate. When the edge contour cutters 11 cut downward, they are located in the middle of two adjacent covers, and exactly cut out the horizontal fixing part contours on both sides of the two adjacent covers. A first cutter 21 is provided on the second station 2. The first cutter 21 is used to cut out a rectangular hole in the middle of two adjacent covers, and first cut off a part of the connecting part of two adjacent covers to be pre-cut. A set of punching mechanisms 31 is provided on the third station 3. First bending mechanisms 41 are provided on both sides of the fourth station 4. The first bending mechanisms 41 are used to bend the horizontal fixing part downward to form a shape. A second cutter 51 is provided on the fifth station 5. The blanking plate is fed step by step (the distance of a single feed is exactly the material length required for a single cover), and after passing through the edge contour cutters 11, the first cutter 21 and the second cutter 51 three times of cutting in sequence, a material block required for a single part is cut off and separated. If the blanking plate is cut off at one time, it is very easy to cause the edges of the cut blanking plate to deform, and the force on the cutter will be greater, which is not convenient for cutting. Then, through the second bending mechanism 61 provided on the sixth station 6, the material block is stamped and bent to form a box body part with an opening on one side, and a single processed cover is formed.

[0026] The device includes a bottom plate 7. On the upper end surface of the bottom plate 7, there are a first cutting hole 71 matched with the edge contour cutter 11, a second cutting hole 72 matched with the first cutter 21, a third cutting hole 73 matched with the punching mechanism 31, and a fourth cutting hole 75 matched with the second cutter 51. The cut waste materials are all discharged from the bottom of the cutting holes. Two grooves 77 are also provided on the upper end surface of the bottom plate 7 near both sides. The length of the grooves 77 covers the sides of the fourth, fifth and sixth stations. On the one hand, the grooves 77 are used for the horizontal fixing part on the blanking plate at the fourth station 4 to bend and form and avoid interference, and also enable it to be translated to the sixth station 6. On the other hand, the end of the grooves 77 on one side of the sixth station 6 can also play a positioning role. When the blanking plate is fed, the already bent horizontal fixing part is pushed against the side wall of the grooves 77, and the step feeding is in place; a top plate 9, the top plate 9 is located above the bottom plate 7 and is slidably matched with the bottom plate 7 through four guide rods 10. The upper end surface of the top plate 9 is connected to a driving device such as a hydraulic press; a movable pressing plate 8, the movable pressing plate 8 is located between the bottom plate 7 and the top plate 9, and a spring is provided between the two.

[0027] The bottom plate 7 is provided with a set of vacuum channels 74 at the fourth station 4. The air inlet of the vacuum channels is located on the upper end surface of the bottom plate 7, and the air outlet is located on the side surface of the bottom plate 7. The air outlet is connected to an external vacuum device. Since the material plate will be cut into individual material blocks by the second cutting knife 51 at the fifth station 5, in order to accurately convey and position the remaining material plate, a vacuum channel 74 is provided to adsorb the upper surface of the bottom plate 7 when conveying the remaining material plate.

[0028] The second bending mechanism 61 includes a bending groove 76, a spring block 612 and a bending punch 611. The bending groove 76 is arranged on the upper end surface of the bottom plate 7 and is located at the sixth station 6. The spring block 612 is arranged to slide fit in the bending groove 76. When the device is in the open state, the upper surface of the spring block 612 is flush with the upper surface of the bottom plate 7. An elastic member 613 is connected between the bottom of the spring block 612 and the bottom plate 7. The bending punch 611 is arranged on the lower end surface of the top plate 9 and passes through the movable pressing plate 8. When the device is in the open state, the lower end surface of the bending punch 611 is higher than the upper end surface of the movable pressing plate 8. When the top plate 9 drives the bending punch 611 to press down, the spring block 612 moves downward to avoid, and after bending, the bending punch 611 moves upward, and the spring block 612 also moves upward to push the bent cover out of the bending groove 76 for blanking.

[0029] A row of ejector pins 614 is arranged in the bending punch 611. The ejector pins 614 slide up and down in the bending punch 611. The lower end surface of the ejector pins 614 passes through the lower end surface of the bending punch 611, and a spring is connected to the upper end surface of the ejector pins 614. When the top plate 9 drives the bending punch 611 to press down, the ejector pins 614 first contact the material plate and press the material plate. The top plate 9 continues to press down the second cutting knife 51 at the fifth station 5 to cut out a single material block from the material plate. In this process, since the ejector pins 614 first contact the material plate and press the material plate to make it not easy to displace, the bending positioning of the second bending mechanism 61 is more accurate, and it can also make the bending punch 611 push the cover out of the surface after bending.

[0030] Two groups of workpiece four positioning blocks are arranged on the upper end surface of the bottom plate 7, which are respectively arranged on both sides of the material plate for feeding guidance and positioning of the material plate.

[0031] The bottom plate 7 is provided with an inclined portion 78 on the side surface away from the incoming material end at the sixth station 6 to facilitate blanking. When the spring block 612 pushes the cover out of the bending groove 76 and is flush with the upper surface of the bottom plate 7, the remaining material plate feeding will push the formed cover out and slide down along the inclined portion 78.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
