[0050] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0054] Combined with the attached Figure 1 As shown in the figure, the first feeding mechanism 2 of this embodiment includes a die storage device 21, a first driving device 22, a first die push plate 23 and a check device 24; a plurality of forming dies are stacked in the die storage device 21 of this embodiment from top to bottom; the first driving device 22 of this embodiment is connected to the first die push plate 23 and is used to drive the die push plate to push the forming die to move to the bead forming device; specifically, the first driving device 22 of this embodiment can be a cylinder.

[0055] The check device 24 of this embodiment is installed on the die storage device 21 and prevents the forming die moved outside the die storage device 21 from moving towards the die storage device 21. Preferably, the check device 24 of this embodiment includes a wedge block 241 and an elastic member 242 connected to each other. The guiding surface of the wedge block 241 is used to guide the forming die to be pushed out of the die storage device 21. When the forming die moves outside the die storage device 21, it abuts against the guiding surface of the wedge block 241 and overcomes the elasticity of the elastic member 242 to completely move outside the die storage device 21. At this time, the check surface of the wedge block 241 is used to prevent the forming die from moving towards the die storage device 21, playing a check role.

[0056] Combined with the attachedFigures 2-5 As shown in the figure, the bead forming device of this embodiment includes a mounting frame 11, a second driving device 12, a second mold push plate 13, and a bending device 14; the second mold push plate 13 of this embodiment is movably mounted on one side of the mounting frame 11, and the second driving device 12 is connected to the second mold push plate 13 and drives the second mold push plate 13 to move in a direction close to or away from the other side of the mounting frame 11.

[0057] Combined with the attached Figures 6-9 As shown in the figure, the second feeding mechanism 3 of this embodiment includes a bead storage device 31 and a bead lifting device 32; the bead lifting device 32 of this embodiment is mounted on one side of the mounting frame 11 and is located between the bead storage device 31 and the mounting frame 11. A plurality of to-be-formed beads are stacked in sequence along the length direction in the bead storage device 31, and the to-be-formed bead at the end close to the mounting frame 11 is located on the bead lifting device 32.

Correspondingly, the bead lifting device 32 of this embodiment is provided with a matching structure 326. When the second driving device 12 drives the second mold push plate 13 to move in a direction close to the other side of the mounting frame 11, the connection structure 131 is connected to the matching structure 326, and the bead lifting device 32 drives the to-be-formed bead thereon to rise from the initial position to the forming position, so that the forming mold pushes the to-be-formed bead to the preset position, and the to-be-formed bead is formed into the first state in the figure. In this state, three sides of the bead are in contact with the three side walls of the forming mold, and the sum of the lengths of the remaining two short sides is the same as the length of the other side wall of the forming mold and forms a certain inclination angle with the other side wall of the forming mold.

[0059] Moreover, when the second driving device 12 drives the second mold push plate 13 to move in a direction away from the other side of the mounting frame 11, the connection structure 131 of this embodiment is connected to the matching structure 326, and the bead lifting device 32 is returned to the initial position for cyclic feeding.

[0060] Preferably, in order to ensure that the strip is formed into a quadrilateral frame structure, a bending device 14 is further installed on the mounting frame 11 in this embodiment. After the forming die pushes the strip to be formed to a preset position, the bending device 14 forms the strip to be formed into the second state in the figure, that is, the remaining two short sides of the strip are attached to the other side wall of the forming die to complete the forming of the strip. Further, the bending device 14 of this embodiment includes a first rotating arm 141, a second rotating arm 142, a third driving device 143 and a fourth driving device 144; the third driving device 143 is connected to the first rotating arm 141 and drives the first rotating arm 141 to rotate; the fourth driving device 144 is connected to the second rotating arm 142 and drives the second rotating arm 142 to rotate; the rotation of the first rotating arm 141 and the second rotating arm 142 forms the strip to be formed from the first state to the second state. The third driving device 143 and the fourth driving device 144 of this embodiment can be any driving structure in the prior art that can generate torque to make the rotating arm rotate, such as a motor or a lever structure, etc.

[0061] Preferably, the strip forming device of this embodiment further includes a separator 15 located on the mounting frame 11. The separator 15 is located between the first rotating arm 141 and the second rotating arm 142 to prevent the two short sides of the strip that are not formed from being attached to each other during forming.

[0062] Further, the connection structure 131 of this embodiment includes a block connected to the second die push plate 13, and the block is provided with a transmission guiding surface; the matching structure 326 of this embodiment includes a second roller (not shown in the figure) installed on the strip lifting device 32, and the second roller cooperates with the transmission guiding surface to realize the rising or falling of the strip lifting device 32.

[0063] Combined with the attached Figure 6 and 7 As shown, the strip lifting device 32 of this embodiment includes an integrally formed connecting plate 321, a first limiting plate 322 and a second limiting plate 323; the first limiting plate 322 and the second limiting plate 323 are respectively connected to opposite sides of the connecting plate 321, and the distance between the first limiting plate 322 and the second limiting plate 323 allows the forming die to pass through. The first limiting plate 322 is provided with a first limiting portion 324, and the second limiting plate 323 is provided with a second limiting portion 325. Both the first limiting portion 324 and the second limiting portion 325 are connected to the strip to be formed to drive the strip to be formed to rise.

One end of the two opposite ends of the storage plate 311 of this embodiment is connected to the bead lifting device 32, and the other end is installed with a movable push plate 312. When the bead lifting device 32 is in the initial position, the bead lifting device 32, the first limit edge 314, the second limit edge 315, and the movable push plate 312 jointly limit a plurality of stacked to-be-formed beads located on the storage plate 311.

[0065] When the bead lifting device 32 is lifted to the forming position, the bead lifting device 32, the first limit edge 314, the second limit edge 315, and the movable push plate 312 also jointly limit a plurality of stacked to-be-formed beads located on the storage plate 311.
