[0025] The principles and features of the present invention are described below in conjunction with all the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] The utility model embodiment discloses a turning mechanism of a material supporting top piece.

[0027] Reference Figure 1-Figure 5 A flipping mechanism for a supporting top member includes a supporting frame 1, a guide rod 4, a slide plate 2, and a flipping assembly. The flipping mechanism is arranged on the lower die base. The supporting frame 1 is used to support the workpiece, and one side of the supporting frame 1 is welded to the slide plate 2. A connecting rod 10 is arranged on the same side of the supporting frame 1, and the connecting rod 10 is welded above the slide plate 2. The slide plate 2 is provided with a slide groove along its length direction, and the slide groove is a waist-shaped groove. The guide rod 4 is vertically arranged, and a U-shaped groove is arranged at the top of the guide rod 4. The slide plate 2 is rotatably located in the U-shaped groove. A pin shaft 9 is horizontally arranged at the top of the guide rod 4. The pin shaft 9 is penetrated through the slide groove, and the pin shaft 9 is located at one end of the slide groove close to the supporting frame 1. The flipping assembly is vertically arranged to drive the supporting frame 1 to rotate. The workpiece is located on the support frame 1, and the flip assembly is started to drive the support frame 1 to rotate. During the rotation of the support frame 1, since one side of the support frame 1 is welded to the slide plate 2, the slide plate 2 can be driven to rotate in the U-shaped groove. Figure 3 As shown, the rotation of the support rack 1 eventually causes the lifted parts to tilt and slide down the mold onto the conveyor belt, completing a process from picking up the parts to conveying them. This process does not require manual picking up of the parts, thus saving time and labor.

[0028] Two guide rods 4 are provided, which are respectively located at two ends of the same side of the bracket 1, so as to improve the rotation stability of the bracket 1.

[0029] A stroke adjustment nut 5 is provided at the lower end of the guide rod 4 . By screwing the stroke adjustment nut 5 , the distance between the stroke adjustment nut 5 and the lower die seat can be changed, that is, the shape of the guide rod 4 can be changed.

[0030] The turning assembly is located in the middle of the two guide rods 4, which further improves the stability of the workpiece rotation.

[0031] The flip assembly includes a circular hole plate 3 welded to the bracket 1, and a cylinder 7 located below the circular hole plate 3. The connecting shaft 6 of the cylinder 7 is connected to the circular hole plate 3 through a second pin 8. The circular hole plate 3 is rotatably connected to the connecting shaft 6 of the cylinder 7. The second pin 8 and the first pin 9 are not on the same horizontal line, and the position of the second pin 8 is higher than that of the first pin 9.

[0032] When one stamping is completed, the cylinder 7 is inflated and pushed up, and the circular hole plate 3 and the bracket 1 are driven to move upward together through the connecting shaft 6 of the cylinder 7. Since the pin shaft 1 9 and the pin shaft 2 8 are not on the same line, under the influence of the gravity of the parts, the friction between the guide rod 4 and the mold base, the pin shaft 2 8 is subjected to an unbalanced force in the horizontal direction, resulting in the rotation of the bracket 1 along the pin shaft 2 8; since the pin shaft 1 9 is installed on one side of the slide slot, the slide slot plate 2 can only slide to the side with space, and at the same time, the circular hole plate 3 rotates in the same direction as the slide slot plate 2. The two work together under the top force of the cylinder 7, so that the bracket 1 rises and rotates at the same time, and finally the supported parts are tilted and slide down the mold to the conveyor belt, completing a process from picking up to conveying. After the cylinder 7 is reversely inflated, the relevant structure is reset, and then the next action is performed.

[0033] Among them, the lifting height and inclination are determined according to the stroke of the cylinder 7. Just turn the stroke adjusting nut 5 to the appropriate position. If the rigidity of the support frame 1 is good and the parts are light, and the friction between the guide rod 4 and the die base hole is small enough, the force at the pin 8 is just in a balanced state, and the support frame 1 also has a flat top for a distance. When the stroke adjusting nut 5 is stuck with the die base, as the cylinder 7 continues to lift, the support frame 1 starts to flip again, which can also achieve the purpose of sliding the parts off.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
