A shrapnel curling and forming method, using the above-mentioned shrapnel curling and forming equipment, adopts the following steps:

S1. The staff places the material in the casing and linearly feeds it through the shrapnel feeding mechanism installed inside the casing. The shrapnel raw material passes through the feeding hole and slides along the straight edge of the stopper to be continuously sent out of the casing;

S2. The drive assembly starts. The drive motor in the drive assembly drives the corresponding cam to start rotating. The convex part of the cam squeezes one end of the corresponding push rod. The other end of the push rod simultaneously slides on the top of the guide rail and pushes the corresponding slider. The seat moves in the direction of the feeding assembly. During this process, the sliding seat drives the connecting block to squeeze the pneumatic spring rod, and the pneumatic spring rod is in a compressed state;

S3. After the driving component corresponding to the positioning component is started through the steps of S2, the corresponding two sliding seats drive the two positioning seats closer to each other. The two positioning seats drive the two positioning pieces to fit each other and pass through the two grooves. A conveying channel is formed, two positioning pieces clamp and assist positioning of the shrapnel raw material, and the shrapnel raw material continues to be transported through the conveying channel formed by the two grooves;

S4. At the same time, after the driving component corresponding to the crimping component is started through the steps of S2, the corresponding two slides drive the upper crimping seat and the insert block to approach each other, and the upper crimping seat drives the crimping motor, column and first clamp. Move synchronously, the insert block drives the lower curling seat, vertical rod, second clamp and arc-shaped part to move synchronously until the first clamp and the second clamp fit together; then the micro motor drives the gear to rotate, and the two gears mesh and the direction of rotation On the contrary, the two second clamps swing along the rotating axis, that is, they are adjusted from the fitting state to the parallel state. The piston rod of the electric rod extends and drives the U-shaped plate to move to one side of the two second clamps, and one end of the elastic material Pass through the gap inside the second clamp and the inside of the U-shaped plate in turn and fit with the outer wall of the column to continue conveying;

S6. If it is necessary to bend the shrapnel material in a small range, first the shrapnel raw material is kept inside the second clamp for transportation, and the column stops rotating. Then it is started by the driving component corresponding to the corner component. The corner component moves as a whole, and the corner seat drives the corner box. The position of the shrapnel is close, and the shrapnel is squeezed according to the need. During the continuous transportation process of the shrapnel, its side is pressed, and the outer wall of the shrapnel bullet column is bent to form a small range of bending angle;

S7. Then, through the feeding of the feeding component and the rotation angle of the curling motor, a large range of bending is performed, and with the small range of bending of the bending component, the elastic material is bent into the required shape, and then the driving component and guide component corresponding to the cutting component are started.

Purpose, good stability and reduced cost;

(2) By setting the gear and the cavity, that is, the micro motor drives the gear to rotate. The two gears mesh and rotate in opposite directions. The two second clamps swing along the rotating axis. By adjusting the opening size between the two second clamps, This facilitates the shrapnel raw material to enter between the two second clamps and avoids the situation where the shrapnel raw material cannot be inserted quickly due to the small shrapnel conveying channel on the curling assembly;

(3) By arranging the U-shaped plate, one end of the shrapnel raw material passes through the gap inside the second clamp and the inside of the U-shaped plate in sequence. The U-shaped plate plays a guiding role in guiding the shrapnel raw material and prevents the shrapnel raw material from passing through the curling assembly. The occurrence of drooping bending affects the curling effect, and the electric rod drives the U-shaped plate to move up and down, so that the elastic material can be switched between the first clamp and the second clamp to avoid the need for the crimping component to separate during the crimping process, causing the raw material to detach.

The two second clamps 48 The opening between them increases, the piston rod of the electric rod 494 stretches out and drives the U-shaped plate 495 to move up to one side of the two second clamps 48, and one end of the elastic material passes through the gap and the U inside the second clamps 48 in turn. The inside of the shaped plate 495 is in contact with the outer wall of the column 43 and continues to be transported.

Step 5: The curling motor 42 drives the column 43 to rotate, and the elastic material inside the first clamp 44 is bent. By controlling the rotation angle of the curling motor 42, a wide range of bending angles of the elastic material are controlled.

Step 6: If it is necessary to bend the elastic fragment material in a small range, first the elastic fragment material is kept inside the second clamp 48 for transportation, the column 43 stops rotating, and then is started by the driving component 2 corresponding to the corner component 7, and the corner component 7 moves as a whole. The angled seat 72 drives the angled piece 73 to move the elastic pieces closer, and squeezes the elastic pieces as needed. During the continuous transportation of the elastic pieces, the sides of the elastic pieces are pressurized, and the outer wall of the elastic piece elastic column 43 is bent to form a small range of bending angle.

Step 7: Then, through the feeding of the feeding component 8 and the rotation angle of the curling motor 42, a large range of bending is performed, and in conjunction with the small range of bending of the bending component 7, the elastic material is bent into the required shape, and then the driving component 2 corresponding to the cutting component 6 is When the guide assembly 3 is activated, the two cutting cutters 63 approach each other to cut and separate the formed elastic fragment workpiece from the unformed elastic fragment raw material.
