A top plate is fixed to the upper end of each guide rod, and a movable plate is slidably connected to the guide rods. A hydraulic cylinder with its output end connected to the movable plate is installed on the upper part of the top plate. A lower mold and an upper mold are slidably connected to the upper part of the base plate and the lower part of the movable plate, respectively. A pair of opposing L-shaped slide rails are fixed to the lower part of the base plate and the upper part of the movable plate, respectively. A pair of positioning components are slidably connected between the pair of L-shaped slide rails. The advantages of this utility model are: the lower mold and the upper mold are slidably connected to the base plate and the movable plate, respectively, and the positioning components and L-shaped slide rails facilitate the installation, disassembly, and replacement of the upper and lower molds, making it suitable for flanging automotive body panels of different sizes.

[0004] The applicant discovered some shortcomings in the use of the patent: the above patent does not have a material ejection function, and after the metal part is pressed down and flipped, it may get stuck in the lower mold and be inconvenient to remove.

[0005] Therefore, this utility model designs a flanged top material positioning mechanism to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this utility model is to provide a flanged top material positioning mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a flanged material positioning mechanism, comprising: a base, a gantry frame mounted on the top of the base, a cylinder mounted at the middle of the top of the gantry frame, an upper die mounted on the output end of the cylinder via bolts, a lower die mounted on the base via bolts directly below the upper die, a through groove between the two ends of the lower die, lead screws rotatably mounted on both sides of the through groove, a lifting plate slidably mounted between the two lead screws via threads, a circular disc mounted on the top of the lifting plate via a support rod, and a through hole for insertion into the circular disc on the top of the lower die. The top of the upper mold has an installation slot, in which an electromagnet is installed. The lower mold has a drive slot below it, in which a drive assembly is installed. A cylinder drives the upper mold to descend, pressing down the metal part placed on the lower mold and flanging the metal part. After flanging, the cylinder drives the upper mold to rise, leaving the metal part on the lower mold. Rotating the lead screw raises the lifting plate, which in turn raises the circular disc via the support rod, lifting the metal part for easy retrieval. The electromagnet is activated simultaneously when the circular disc rises, attracting the metal part and preventing it from shifting during ascent. This positioning of the metal part facilitates the gripping of the workpiece by robots or automated equipment.

[0008] Preferably, a scale is installed on one inner wall of the through groove. When the lifting plate rises and falls, the distance the lifting plate rises can be known by the scale, which makes it convenient to lift the metal parts to different heights.

[0009] Preferably, there are two support rods, and the tops of the two support rods are fixedly installed to the bottom sides of the circular disk, respectively. The two support rods can improve the stability of the circular disk.

[0010] Preferably, the top of the electromagnet is provided with a wear-resistant layer, which is a TPU film and is adhered to the top of the electromagnet to reduce wear on the surface of the electromagnet.

[0011] Preferably, the drive assembly includes a drive motor, which is installed in the drive slot. The output end of the drive motor is connected to the bottom of a lead screw. A sprocket is installed below the outer side wall of the lead screw, and a chain meshes between the two sprockets. Through the meshing of the sprockets and the chain, one drive motor can drive two lead screws to rotate simultaneously, saving the use of one motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. After the flanging is completed, the screw is rotated to raise the lifting plate, and the circular disc is raised through the support rod to lift the metal part upward for easy material handling. Before lifting, the electromagnet is energized so that it can attract the bottom of the metal part and position it to prevent it from shifting after being lifted. After the metal part is lifted and positioned, it is convenient for robots or automated equipment to grasp the workpiece. Attached Figure Description

[0021] Please see Figure 1-3 In this embodiment: there are two support rods 9, and the tops of the two support rods 9 are fixedly installed on the bottom sides of the circular disk 10 respectively.

[0022] Please see Figure 1-3 In this embodiment: the top of the electromagnet 13 is provided with a wear-resistant layer, which is a TPU film. The wear-resistant layer does not affect the magnetic force of the electromagnet 13 and reduces the wear on the top of the electromagnet 13.

[0023] Please see Figure 1-3 In this embodiment: the drive assembly 16 includes a drive motor 161, which is installed in the drive groove 15. The output end of the drive motor 161 is connected to the bottom of a lead screw 7. A sprocket 162 is installed below the outer side wall of the lead screw 7, and a chain 163 meshes between the two sprockets 162.

[0024] Working principle: The metal part is placed on top of the lower mold 5. Then, the cylinder 3 drives the upper mold 4 to press down the metal part, which can make the edge of the metal part flip up, achieving the flanging. Then, the cylinder 3 drives the upper mold 4 to rise. The metal part is stuck on the lower mold 5 and difficult to remove. The drive motor 161 can be started to rotate one lead screw 7. Through the meshing of the sprocket 162 and the chain 163, the other lead screw 7 is rotated at the same time, which can raise the lifting plate 8. The support rod 9 raises the circular disk 10, lifting the flanged metal part for easy removal. When ejecting, the electromagnet 13 is activated. After the electromagnet 13 is energized, it attracts the metal part, which can prevent the metal part from shifting after rising during ejection. It plays a positioning role for the metal part, making it convenient for robots or automated equipment to grasp the workpiece. The lifting distance of the circular disk 10 can be adjusted by the scale 14, which can easily lift the metal part to the required height, further facilitating robots or automated equipment to grasp the workpiece at different heights.
