Description

Technical Field

[0001] This utility model relates to the field of U-shaped nail forming technology, and more specifically to a U-shaped nail forming device. Background Technology

[0002] U-shaped nails, as a high-efficiency and economical metal connector, are widely used in many fields such as building decoration, furniture manufacturing, product packaging, agriculture and daily life. They are used to fix various materials such as boards, cables, and mesh. Their forming quality and production efficiency are directly related to the cost and reliability of downstream applications. Traditional U-shaped nail manufacturing primarily relies on multi-station cold heading technology. This process typically involves continuous steps such as wire straightening, feeding, cutting, pre-bending, and final bending. Specifically, the wire rod is first straightened by a straightening mechanism, and then precisely pushed to a predetermined length by a feeding mechanism. Next, a cutting die cuts the wire into nail blanks of a fixed length. Finally, a pair of precisely matched forming dies simultaneously bend both ends of the nail blanks under stamping action to form a standard U-shape. Currently, during the forming process, after the stamping device completes the forming, it is necessary to remove the formed U-shaped nails. However, it is not possible to automatically and quickly remove the U-shaped nails, resulting in low processing efficiency. Furthermore, there is no suitable mechanism to place the U-shaped nails after they are removed, making the collection of U-shaped nails scattered everywhere quite complicated. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a U-shaped nail forming device to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a U-shaped nail forming device, including a support frame, a lifting plate movably connected to the top of the support frame, an upper forming mold fixedly connected to the bottom of the lifting plate, a lower forming mold fixedly connected to the side of the support frame, the upper forming mold and the lower forming mold closing to press and form U-shaped nails, an ejection mechanism fixedly connected to the side of the support frame away from the upper forming mold, and a collecting mechanism fixedly connected to the side of the lower forming mold away from the support frame; the ejection mechanism includes a support plate fixedly connected to the support frame, a protective frame fixedly connected to the top of the support plate away from the support frame, an electromagnet fixedly connected inside the protective frame, a magnetic plate movably connected to the side of the electromagnet away from the protective frame, and an ejection rod fixedly connected to the side of the magnetic plate away from the electromagnet.

[0005] Furthermore, there are three ejector rods, which are located at the top and sides of the U-shaped nail. When the magnetic plate is in contact with the electromagnet, the ejector rods are located inside the support frame and do not contact the lower forming mold. After the electromagnet is energized, the ejector rods push the U-shaped nail off the lower forming mold.

[0006] Furthermore, a limiting rod is fixedly connected to the side of the magnetic plate away from the electromagnet, a limiting cylinder is provided on the side of the limiting rod away from the magnetic plate, a supporting spring is provided on the side of the limiting rod and the limiting cylinder, and the side of the limiting cylinder away from the limiting rod is fixedly connected to the side of the support frame.

[0007] Furthermore, the collecting mechanism includes a support shaft plate fixedly connected to the lower forming mold. The side of the support shaft plate away from the lower forming mold is inclined downward. A rotating plate is movably sleeved on the side of the support shaft plate away from the lower forming mold. A fixed shaft is movably sleeved on the side of the rotating plate away from the support shaft plate.

[0008] Furthermore, sliding plates are fixedly connected to both sides of the fixed shaft, a fixed rod is movably connected to the bottom of the sliding plate, a lifting block is fixedly connected to the bottom of the fixed rod, a limit box is movably connected to the side of the lifting block, and a support leg is fixedly connected to the bottom of the limit box.

[0009] Furthermore, a limit block is fixedly connected to the bottom end of the side of the lifting block, and a sliding groove is provided inside the limit box for the limit block to move. A threaded rod is threadedly connected to the bottom end of the lifting block, and an adjusting wheel is fixedly connected to the bottom end of the threaded rod.

[0010] The technical effects and advantages of this utility model are as follows: 1. This utility model uses an electromagnet, a magnetic plate, and ejector rods. After the upper and lower forming molds are closed to form a U-shaped nail, the electromagnet is activated and generates a magnetic repulsion force between itself and the magnetic plate. Under the action of the magnetic repulsion force, the magnetic plate moves away from the electromagnet. When the magnetic plate moves, it drives the three ejector rods to move. The three ejector rods bring the top of the U-shaped nail into contact with the two sides, thereby automatically ejecting the formed U-shaped nail, which facilitates the unloading process.

[0011] 2. After the ejection mechanism of this utility model ejects the U-shaped nail, the U-shaped nail will fall above it. At this time, it will move downward through the inclined support shaft plate and fall onto the rotating plate for collection. The adjustable wheel can be rotated. When the adjustable wheel rotates, it drives the threaded rod to rotate. When the threaded rod rotates, it drives the lifting block and the fixed rod to move up and down, thereby adjusting the angle of the rotating plate. When the tilt angle of the rotating plate is larger, the U-shaped nail falls faster, avoiding blockage. When the tilt angle is smaller, the U-shaped nail moves slowly. At this time, it can be detected. This application can automatically adjust the collection speed. Attached Figure Description

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Reference Figure 1 and Figure 2 This utility model provides a U-shaped nail forming device, including a support frame 1, a lifting plate 2 movably connected to the top of the support frame 1, an upper forming mold 3 fixedly connected to the bottom of the lifting plate 2, a lower forming mold 4 fixedly connected to the side of the support frame 1, the upper forming mold 3 and the lower forming mold 4 are closed to press and form U-shaped nails, an ejection mechanism 5 is fixedly connected to the side of the support frame 1 away from the upper forming mold 3, and a collection mechanism 6 is fixedly connected to the side of the lower forming mold 4 away from the support frame 1.

[0020] In this embodiment, after the upper forming mold 3 and the lower forming mold 4 are closed to press and form U-shaped nails, the ejection mechanism 5 automatically pushes out the formed U-shaped nails, and the U-shaped nails are pushed onto the collection mechanism 6 for collection, so as to carry out rapid forming production of U-shaped nails, and the collection will not cause damage to the environment.

[0021] Reference Figure 2 and Figure 3 The ejection mechanism 5 includes a support plate 501 fixedly connected to the support frame 1. A protective frame 502 is fixedly connected to the top of the support plate 501 away from the support frame 1. An electromagnet 503 is fixedly connected inside the protective frame 502. A magnetic plate 504 is movably connected to the side of the electromagnet 503 away from the protective frame 502. Ejection rods 505 are fixedly connected to the side of the magnetic plate 504 away from the electromagnet 503. There are three ejection rods 505, located at the top and sides of the U-shaped nail. The magnetic plate 504 and... When the electromagnet 503 is in contact, the ejector rod 505 is located inside the support frame 1 and does not contact the lower forming mold 4. After the electromagnet 503 is energized, the ejector rod 505 pushes the U-shaped nail off the lower forming mold 4. The side of the magnetic plate 504 away from the electromagnet 503 is fixedly connected to the limiting rod 506. The side of the limiting rod 506 away from the magnetic plate 504 is provided with the limiting cylinder 507. The side of the limiting rod 506 and the limiting cylinder 507 is provided with the supporting spring 508. The side of the limiting cylinder 507 away from the limiting rod 506 is fixedly connected to the side of the support frame 1.

[0022] In this embodiment, the electromagnet 503 is energized and generates a magnetic repulsion force with the magnetic plate 504. Under the action of the magnetic repulsion force, the magnetic plate 504 moves away from the electromagnet 503. When the magnetic plate 504 moves, it drives the ejector rod 505 to move and compresses the support spring 508. When the ejector rod 505 moves, it contacts the top and sides of the U-shaped nail, thereby pushing the U-shaped nail onto the support shaft plate 601. After the U-shaped nail is pushed away, the electromagnet 503 is de-energized. At this time, the support spring 508 resets and drives the magnetic plate 504 to reset. The limiting rod 506 moves within the limiting cylinder 507 to ensure the stability of the magnetic plate 504 during movement. The protective frame 502 protects the electromagnet 503 to prevent damage to the electromagnet 503. When the magnetic plate 504 contacts the electromagnet 503, the ejector rod 505 is located within the support frame 1 and does not contact the lower forming mold 4, so as to prevent the ejector rod 505 from affecting the mold closing of the upper forming mold 3 and the lower forming mold 4.

[0023] Reference Figure 3 , Figure 4 as well as Figure 5The collecting mechanism 6 includes a support shaft plate 601 fixedly connected to the lower forming mold 4. The side of the support shaft plate 601 away from the lower forming mold 4 is inclined downward. A rotating plate 602 is movably sleeved on the side of the support shaft plate 601 away from the lower forming mold 4. A fixed shaft 603 is movably sleeved on the side of the rotating plate 602 away from the support shaft plate 601. Sliding plates 604 are fixedly connected to both sides of the fixed shaft 603. A fixed rod 605 is movably connected to the bottom end of the sliding plate 604. A lifting block 606 is fixedly connected to the bottom end of the fixed rod 605. A limit box 607 is movably connected to the side of the lifting block 606. A support leg 611 is fixedly connected to the bottom end of the limit box 607. A limit block 608 is fixedly connected to the bottom end of the side of the lifting block 606. A groove is provided inside the limit box 607 for the limit block 608 to move. A threaded rod 609 is threadedly connected to the bottom end of the lifting block 606. An adjusting wheel 610 is fixedly connected to the bottom end of the threaded rod 609.

[0024] In this embodiment, the side of the support shaft plate 601 away from the lower forming mold 4 is tilted downwards. The U-shaped nails will fall onto the rotating plate 602 through the support shaft plate 601. The side of the rotating plate 602 away from the support shaft plate 601 is tilted downwards. Therefore, the U-shaped nails pushed onto the rotating plate 602 will accumulate on the rotating plate 602 for easy collection later. When the adjusting wheel 610 is rotated, it drives the threaded rod 609 to rotate. When the threaded rod 609 rotates, it causes the lifting block 606 to move downwards. When the lifting block 606 moves downwards, it drives the fixed rod 605 and the sliding plate 604 to move downwards, thereby increasing the tilt angle of the rotating plate 602 and improving the material dropping speed. When the rotating plate 602 is tilted, the sliding plate 604 will move to the side of the fixed rod 605 to ensure the stability of the tilt of the rotating plate 602.

[0025] The working principle of this utility model is as follows: When the U-shaped nail is formed, the raw material wire of the U-shaped nail is fed between the upper forming mold 3 and the lower forming mold 4. At this time, the lifting plate 2 drives the upper forming mold 3 to descend, and the upper forming mold 3 and the lower forming mold 4 close, thereby forming the U-shaped nail. After the U-shaped nail is formed, the electromagnet 503 is energized and generates a magnetic repulsion force between it and the magnetic plate 504. Under the action of the magnetic repulsion force, the magnetic plate 504 moves away from the electromagnet 503. When the magnetic plate 504 moves, it drives the ejector rod 505 to move and compresses the support spring 508. When the ejector rod 505 moves, it contacts the top and sides of the U-shaped nail, thereby pushing the U-shaped nail onto the support shaft plate 601. After the U-shaped nail is pushed away, the electromagnet 503 is de-energized. At this time, the support spring 508 is reset and drives the magnetic plate 504 to reset, thereby causing the ejector rod 505 to move away from between the upper forming mold 3 and the lower forming mold 4 for the next U-shaped nail forming. After the U-shaped nails are pushed above the support shaft plate 601, the support shaft plate 601 tilts itself and falls onto the rotating plate 602. The rotating plate 602 tilts downward away from the side of the support shaft plate 601, so the U-shaped nails pushed onto the rotating plate 602 will accumulate on the rotating plate 602 for easy collection later. When rapid collection is needed, the adjusting wheel 610 is rotated. When the adjusting wheel 610 rotates, it drives the threaded rod 609 to rotate. When the threaded rod 609 rotates, it causes the lifting block 606 to move downward. When the lifting block 606 moves downward, it drives the fixed rod 605 and the sliding plate 604 to move downward, thereby increasing the tilt angle of the rotating plate 602 and increasing the material dropping speed.

[0026] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
