Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0029] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] Reference Figure 1-10 As shown, a stamping, bending and cutting integrated device has an elongated upper die base 5 and a lower die base 6 for continuous processing, and a drive mechanism (not shown in the figure) to drive the upper die base 5 to move up and down. The drive mechanism is preferably a hydraulic drive mechanism, which has a larger load and a mature and stable structure. Between the upper die base 5 and the lower die base 6, from the feeding end to the discharging end, there are a first cutting station 1, a first bending station 2, a second bending station 3 and a second cutting station 4.

[0031] The continuous strip enters from the feeding end and first passes through the cutting station to cut the outline of the fixed part 8 on the adjacent side of the two connected shells. The bottom 7 of the shell is not cut off to facilitate the feeding and movement of the strip. Then, the first bending station 2 bends the fixed parts 8 on both sides of the shell. Then, the second bending station 3 bends the connection between the fixed part 8 and the inclined part 9 of the shell and the bottom 7. Finally, the stamped and bent shell is cut off from the continuous strip through the second cutting station 4. The strip is formed by continuous stamping, bending and cutting. It does not require manual intervention to transport it to different devices for multiple processing, which can improve production efficiency. In addition, there is no need for repeated positioning in multiple devices during the production process. It is only necessary to control the feeding amount of the strip to improve the dimensional accuracy of the shell.

[0032] Specifically, the first cutting station 1 is provided with two first cutting blades 11 located on both sides of the strip. The edge shape of the first cutting blades 11 is set according to the outline of the fixing part 8. The lower mold base 6 is provided with a first lower mold hole that cooperates with the first cutting blades 11. The two cooperate to cut the strip, and the cut waste is easily discharged from the first lower mold hole. The lower end face of the upper mold base 5 located at the first cutting station 1 is elastically connected to a first pressure plate 13. The first cutting blades 11 are fixed to the upper mold base 5. When the mold is open, the lower end face of the first cutting blades 11 is higher than the lower end face of the pressure plate. When cutting, the first pressure plate 13 first contacts the strip and presses it against the upper end face of the lower mold base 6. The upper mold base 5 continues to press down the first cutting blades 11 to contact the strip for cutting.

[0033] Specifically, the upper end face of the lower die base 6 is provided with four first punches 21 and two second punches 22 at the first bending station 2. The lower end face of the upper die base 5 is provided with a third punch 23 that works with the first punches 21 and the second punches 22. The third punch 23 moves downward and cooperates with the first punches 21 to bend the fixed part 8. It cooperates with the second punches 22 to bend the outer edge of the inclined part 9. By cooperating with the first punches 21, the second punches 22 and the third punch 23, the parts that are not easy to bend in one go are bent first. The complexity of the device structure is reduced by bending in steps.

[0034] Specifically, the upper end face of the lower die base 6 is provided with two fourth punches 31 at the second bending station 3, and the lower end face of the upper die base 5 is provided with a fifth punch 32. The fifth punch 32 moves downward and cooperates with the two fourth punches 31 to bend the connection between the fixed part 8 and the inclined part 9 and the bottom 7. Thus, the stamping and bending of a single shell is completed.

[0035] Specifically, the final second cutting station 4 includes a second cutting blade 41, and the lower mold base 6 is provided with a second lower mold hole that cooperates with the second cutting blade 41. The second cutting blade 41 is fixed to the upper mold base 5.

[0036] Specifically, the first cutting station 1 is also provided with six guide blocks 12 for limiting the position of the strip. The guide blocks 12 are fixed to the upper end face of the lower mold base 6 and distributed on both sides of the strip to limit the displacement of the strip in both directions.

[0037] Specifically, the lower mold base 6 is equipped with several vertical spring ejector pins (not shown in the figure). After the upper mold base 5 completes one downward press, the strip adheres to the lower mold base 6, and the spring ejector pins push the strip upward to facilitate the movement of the strip.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
