Figure 1 The distance, or dimension, between the front and rear sides of the indicated position is the free side.

Figure 1 and Figure 2 The car seat adjuster upper connecting plate 10 obtained by the processing device shown has its function and connection with related components already mentioned by the applicant in the background section above, so only a brief description is given below. The entire car seat adjuster upper connecting plate 10 tends to have a zigzag or Z-shaped structure, with the front and rear sides of the left end being a left end single folded edge 101 and the area at the right end being a right end single folded edge 102. However, after processing by the processing device of this utility model, an inner and outer folded edge 103 of the adjuster upper connecting plate, composed of an inner folded edge 1031 and an outer folded edge 1032, is formed between the right end single folded edge 102 and the left end single folded edge 101. This inner and outer folded edge 103 of the adjuster upper connecting plate can also be called a composite folded edge or a double folded edge, and has the good technical effects described by the applicant in the technical effects section above.

[0035] Applicant description by Figure 1 and Figure 2 The above-described structure is produced by the processing device for the connecting plate of the car seat adjuster with an inward folded edge. Figure 3The process of connecting plate 10 of the car seat adjuster with the structure shown. Assuming that the aforementioned pressure plate fixing connecting plate 1 is fixed to the stamping column of the stamping device and the aforementioned worktable fixing connecting plate 2 is fixed to the worktable of the stamping device, then the flat plate blank of the car seat adjuster connecting plate obtained by the previous blanking die (also called cutting die or punching die) is placed on the lower die 6 and the lower buffer seat 72 corresponding to the structure system of the lower buffer mechanism 7 provided in the lower die cavity 61 is started by the aforementioned stamping device. The stamping column causes the pressure plate fixing connecting plate 1 to move downward, driving the first, second, third, fourth, and fifth pressure plates 41, 42, 43, 44, and 45 to move downward together. In the aforementioned process, the outer folding stamping die 441 (also referred to as the "single folding stamping die for the upper connecting plate of the angle adjuster," as in the previous example) and the outer folding stamping die 442 (also referred to as the "single folding stamping die for the right end of the upper connecting plate of the angle adjuster," as in the previous example) respectively stamp and form the shape of the upper connecting plate blank of the aforementioned car seat angle adjuster on the aforementioned car seat angle adjuster upper connecting plate blank. Figure 3 The left end single fold 101 and the right end single fold 102 are shown. Simultaneously, during the aforementioned process, the upper die 8 for pressing the inner and outer folds of the connecting plate on the angle adjuster also moves downwards. As it moves downwards towards the lower die cavity 93 for pressing the inner and outer folds of the connecting plate on the angle adjuster, the front and rear halves 91 and 92 of the aforementioned lower die 9 for pressing the inner and outer folds of the connecting plate on the angle adjuster will separate, forming openings (i.e., opening up to each other) on opposite sides of the front and rear inner folds 912 and 922. With the downward pressure of the upper die 8 for pressing the inner and outer folds of the connecting plate on the angle adjuster, the lower die... Cavity 61 forms the aforementioned outer folded edge 1032 on the connecting plate 10 of the car seat adjuster. When the lower buffer mechanism 7 sinks or descends to the bottom of the lower mold cavity 61, that is, when it descends to its limit, that is, when the aforementioned set of buffer springs 73 is compressed to its limit, the aforementioned front and rear half mold support folded edges 911 and 921 are subjected to pressure, causing the outer folded edge 1032 already formed on the lower surface of the front and rear inner folded edge forming flanges 912 and 922 to be squeezed, thereby forming a... Figure 3 The inner folded edge 1031 is shown.

[0036] When the punch column of the stamping device moves upward, it is displaced upward together with the first, second, third, fourth, fifth pressing plates 41, 42, 43, 44, 45, the outer flange stamping die 441 of the upper connecting plate of the angle adjuster, the right end outer flange stamping die 442 of the upper connecting plate of the angle adjuster, and the upper and lower dies 8, 9 of the inner and outer flange stamping of the upper connecting plate of the angle adjuster, the lower buffer mechanism 7 makes the lower buffer seat 72 float upward together with the automobile seat angle adjuster upper connecting plate 10 formed by stamping and forming above the lower buffer seat 72 under the action of the restoring force of a set of lower buffer springs 73, and the automobile seat angle adjuster upper connecting plate 10 formed by stamping and forming is taken away by a robot or by an on-line operator. The next round of repeated actions is entered until the required number of automobile seat angle adjuster upper connecting plate blanks in the form of flat plates obtained by blanking from the blanking die are stamped and formed into Figure 3 When the pressing plate fixed connecting plate 1 moves upward, it is buffered by the upper buffer mechanism 5, and when the pressing plate fixed connecting plate 1 moves downward, the downward movement of the first, second, third, fourth, fifth pressing plates 41, 42, 43, 44, 45 and the like is assisted by the release, i.e. the restoring force, of a set of buffer springs 52 of the structural system of the upper buffer mechanism 5.

[0037] In summary, the technical scheme provided by the utility model makes up for the shortcomings in the prior art, successfully completes the invention task, and truly realizes the technical effects described by the applicant in the technical effect column above.
