[0001] This utility model belongs to the field of automatic tip cutting technology for shaped nails, and specifically relates to an automatic tip cutting device for shaped nails. Background Technology

[0002] Existing U-shaped nail (also known as saddle nail, saddle rivet) production equipment typically employs a step-by-step processing method: first, the wire is cut; then, it is bent into shape using a mold; and finally, the nail feet are cut off. This process involves dispersed steps, requires a large equipment footprint, and makes it difficult to maintain consistent precision in forming and tip cutting, affecting the nail's performance. Furthermore, traditional equipment is complex to adjust and adapt to the production needs of nails of various sizes. Therefore, it is necessary to provide a highly integrated and automated device that can complete nail bending and tip cutting in one operation. In furniture manufacturing, especially for fixing materials such as leather and seat panels, nails are often used for connection. Traditional flat-angle nails have the following problems during the nailing process: high resistance during driving, requiring considerable effort; flat-angle nails easily damage the product surface, especially delicate materials such as leather, affecting the product's appearance and quality.

A wire guide groove 7 is provided on one side of the bending head 4. A wire guide fixing block 6 is provided on the wire guide groove 7, and a cutting bit 3 is provided at the outlet of the wire guide groove 7. The bending head compression rod shrinkage groove 9 and the bending head shrinkage groove 8 are connected in series. The bending head shrinkage groove 8 is located at the bottom of the forming nail shaping and cutting groove 12. The depth of the bending head shrinkage groove 8 is greater than the height of the bending head 4, and the bottom of the bending head 4 is connected to the bottom of the bending head shrinkage groove 8 by a spring. The depth of the bending head compression rod shrinkage groove 9 is greater than the height of the bending head compression rod 5, and the bottom of the bending head compression rod 5 is connected to the bottom of the bending head compression rod shrinkage groove 9 by a spring. The length and width of the forming nail shaping and cutting groove 12 are both greater than the length and width of the bending head shrinkage groove 8. The nail cutting rod 2 consists of a drive module 22, a left nail cutting rod 23, a right nail cutting rod 24, a bending head compression rod drive module 25, and a bending head inlet through hole 26.

The drive module 22 is fixed at the top of the left nail cutting rod 23, the right nail cutting rod 24, and the bending head compression rod drive module 25. The bending head inlet through hole 26 is fixed between the left nail cutting rod 23 and the right nail cutting rod 24 and is located below the bending head compression rod drive module 25. The left cutting rod 23 and the right cutting rod 24 on the cutting rod 2 are located in the forming nail shaping and cutting groove 12. The left cutting rod 23 is located between the outlet of the guide wire groove 7 and the bending head 4, and the right cutting rod 24 is located on the other side of the bending head 4.

Then, the cylinder drives the cutting rod 2 through the cylinder interface 11. The cutting rod 2 slides downward, and the left cutting rod 23 and the right cutting rod 24 pass through both sides of the bent wire head 4, pressing the nail wire downward. The nail wire is pressed onto the blade 3 and cut by the blade 3. The left cutting rod 23 and the right cutting rod 24 continue to move downward. Press down until the nail wires on both sides of the bending head 4 bend downwards by 90 degrees. The bending head compression rod drive module 25 then presses the bending head compression rod 5 downwards. The bending head compression rod 5 sinks into the bending head compression rod shrinkage groove 9. At the same time, the bending head compression rod 5 drives the bending head 4 to sink into the bending head shrinkage groove 8. Under the continued downward pressure of the left cutting rod 23 and the right cutting rod 24, and the shrinkage of the bending head 4 into the bending head shrinkage groove 8, the forming nail falls out of the forming nail shaping and cutting groove 12.
