However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0017] Example 1

[0018] See Figures 1 to 4As shown, the toothed bowl side-push stamping mechanism involved in this embodiment includes a lower die assembly 1 and an upper die assembly 2 that moves up and down relative to the lower die assembly 1. The lower die assembly 1 is provided with a first material channel 3 that extends forward and backward. The upper end of the first material channel 3 is open. Below the first material channel 3, there is a second material channel (unmarked) that extends left and right and communicates with it. The second material channel is provided with a fixed positioning plate 4 arranged on the left and a movable positioning plate 5 arranged on the right. The movable positioning plate 5 is positioned relative to the fixed positioning plate 4. The positioning plate 4 moves left and right. The first material channel 3 is provided with a lower stamping die 25 located directly above the second material channel. The lower stamping die 25 has a stamping die hole 6 that runs vertically through it. The upper stamping die 7 is provided directly above the lower stamping die 25 and is provided with a stamping die head 8 that matches the stamping die hole. A toothed die hole 9 is provided between the fixed positioning plate 4 and the movable positioning plate 5 and is provided on the lower die assembly. The toothed die head 10 is provided on the upper die assembly 2 directly above the toothed die hole 9.

[0019] Furthermore, the stamping die hole 6 is provided with a limiting component to restrict the workpiece from falling; the limiting component includes a locking tongue 11 that slides radially, the locking tongue 11 is provided with a first limiting part 12 to restrict it from sliding off the stamping die, the stamping die 25 is provided with a second limiting part (not shown) that matches the first limiting part, a first elastic element 13 that resets the locking tongue 11 is provided behind it, the first elastic element 13 is a compression spring embedded in the stamping die; the top of the locking tongue 11 has a guide slope 14.

[0020] Furthermore, the movable positioning plate 5 has a guide rod 15 extending to the left and right at one end facing away from the fixed positioning plate. One end of the guide rod 15 is connected to the lower mold assembly 1, and the other end is provided with an elastic element fixed limiting plate 16. An elastic element movable limiting plate 17 is slidably connected to the guide rod 15. The elastic element movable limiting plate 17 is connected to the movable positioning plate 5. A second elastic element 18, which is a compression spring, is slidably connected to the guide rod 15, with one end abutting against the elastic element fixed limiting plate and the other end abutting against the elastic element movable limiting plate. The elastic element movable limiting plate 17 is provided with a driven push block 19, and the driven push block 19 is provided with a driven guide slope 20. Above the driven push block 19 is an active push block 21 provided on the upper mold assembly. The active push block 21 is provided with an active guide slope 22 that matches the driven guide slope.

[0021] In this embodiment, when the upper mold assembly 2 moves downward, it will be linked to the active push block 21 to push the driven push block 19, causing the movable positioning plate 5 to move aside and free up the area below the stamping die hole 6. At the same time as the upper mold assembly 2 moves downward, it also closes with the lower mold assembly 1 to stamp and form the intermediate material of the toothed bowl without the toothed part. After that, the upper mold assembly 2 moves upward, the active push block 21 is withdrawn, and the driven push block 19, under the deformation recovery force of the second elastic element 18, drives the movable positioning plate 5 to move and push the intermediate material of the toothed bowl located between the movable positioning plate 5 and the fixed positioning plate 4 until it is clamped by the movable positioning plate 5 and the fixed positioning plate 4. At this time, the intermediate material of the toothed bowl is located directly above the toothed die hole 9. In the next mold closing action, the toothed die head 10 presses the workpiece into the toothed die hole 9 until the edge teeth are bent and automatically unloaded.

[0022] Among them, the setting of the limiting component is used to pre-position the upper workpiece in the stacked workpieces.

[0023] The present invention relates to a toothed bowl side-push stamping mechanism, which integrates multi-process stamping and tooth-flipping into one unit, eliminating the need for secondary feeding, resulting in high processing efficiency, complete overall functions, and strong practicality.
