Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The present invention provides, as Figure 1-6 shown, a forming and bending tooling for production track elastic bars, including a lower connecting and mounting base 8 and side mounting groove columns 2 arranged on the lower connecting and mounting base 8;

[0026] At the inner side position of the side mounting groove column 2, a connecting and moving upper template 1 is arranged. At the middle position of the connecting and moving upper template 1, a connecting lower template 3 is arranged. Near the side position inside the connecting lower template 3, a driving connecting gear 9 is arranged. At the front side position of the driving connecting gear 9, a curling roller II 6 is arranged. At the upper side position of the curling roller II 6, a curling roller I 5 is arranged. At the middle position of the connecting lower template 3, a pushing plate 4 is arranged. At the rear side position of the pushing plate 4, a jacking driving cylinder 11 is arranged. An arc-shaped edge is arranged on the side mounting groove column 2. When the connecting and moving upper template 1 moves downward, it drives the driving connecting gear 9 to perform circumferential rotation. The curling roller II 6 and the curling roller I 5 are installed at the flange of the driving connecting gear 9. The elastic bar round bar is placed on two fixed rollers. Through the circumferential rotation of the curved rod rollers, the processed elastic bar 10 arranged in the middle is curled into a circle. Pushed forward by the cylinder, the elastic bar is stripped from the fixed rollers. Through the improvement of the present invention, it can effectively avoid generating indentation when the elastic bar is formed, facilitate detachment after forming, and is not easy to be scratched, etc. Therefore, its use practicability can be effectively improved.

[0027] As Figure 1 shown, the middle position of the inner side of the side mounting groove column 2 is a chute structure, and the upper ends at both ends of the chute are arc-shaped structures, which can facilitate the connecting and moving upper template 1 to insert and hide the rack, and the arc-shaped structure can assist in curling the processed elastic bar 1 into a roll.

[0028] As Figure 1 shown, an upper connecting plate 7 is arranged at the upper end position of the connecting and moving upper template 1. The upper connecting plate 7 and the connecting and moving upper template 1 are of an integral structure. The upper connecting plate 7 plays a connecting role, which can enable the two connecting and moving upper templates 1 on both sides to move better in the same direction at the same time.

[0029] As Figure 4 , Figure 5 and Figure 6As shown in the figure, a plug-in slot is provided at the front side position of the side mounting groove column 2. An insertion mounting connection column 12 is connected in the middle of the plug-in slot. The insertion mounting connection column 12 is connected to the side mounting groove column 2 by an insertion method. A connecting telescopic outer column 13 is provided at the side position of the insertion mounting connection column 12. A telescopic inner connection column 16 is provided at the middle position of the connecting telescopic outer column 13. A scale bar is provided at the upper surface position of the telescopic inner connection column 16. A connecting telescopic spring 14 is provided at the side of the telescopic inner connection column 16 and inside the connecting telescopic outer column 13. The telescopic inner connection column 16 is inserted and telescopically connected to the connecting telescopic outer column 13 through the connecting telescopic spring 14. During use, the processing spring strip 10 can be more conveniently positioned in the middle position by contacting the slope surface block 18. Its setting can correct the processing spring strip 10, so that the forming effect during tooling processing is better, effectively avoiding the phenomenon that the spring strip cannot be used subsequently due to incomplete forming caused by the deviation of the placement position.

[0030] As Figure 4 , Figure 5 and Figure 6 shown, a transparent small hole 15 is provided at the front side position of the connecting telescopic outer column 13. A transparent protective shell is embedded in the middle of the transparent small hole 15. The setting of the transparent small hole 15 facilitates observing whether the scales on the telescopic inner connection column 16 are consistent, so as to judge whether the spring strip is in the middle position.
