Description

Technical Field

[0002] Hook nails are widely used in the process of pipeline installation. They are used to assist in fixing the pipes in the middle of the pipes when installing water pipes. Existing hook nails often include a nail body and a hook arm. The hook arm is directly welded and fixed to the nail body, so that the overall structure of the hook nail is firm and stable. When the nail body is driven into the wall, the nail arm can stably clamp the pipeline, and the overall use effect is better.

[0003] Generally speaking, the existing hook nail processing method usually requires three separate processes, using a nail making machine to process and shape the nail body, using a punch press to stamp and shape the hook arm, and then transferring the processed nail body and hook arm to the hook nail automatic welding machine, and using the hook nail automatic welding machine to weld and fix the hook arm to the nail body, so that the nail body and the hook arm are fixedly connected as a whole. As a result, the entire processing process of the hook nail is relatively large and complicated, and the number of processing equipment is large, resulting in high equipment investment costs, and the equipment occupies a large area.

[0049] like Fig. 9 As shown, the hook arm transmission assembly 51 includes a second cam 511, a second support frame 512 and a second lever 513. The second cam 511 is fixedly mounted on the right transmission shaft 142. The middle part of the second lever 513 is rotatably connected to the second support frame 512.

At the same time, when the rolling lifting rod 5132 swings upward, it can drive the rolling slide 524 to move upward. By adopting this structure, when the right transmission shaft 142 rotates, the second push rod 5131 can be pushed downward by the second cam 511. Through the lever principle, at this time, the rolling lifting rod 5132 can be flipped upward, thereby driving the rolling slide 524 to move upward. When the rolling slide 524 moves upward, it can drive the movable pressure roller 522 to move upward along the guide groove 5261. Therefore, with the cooperation of the fixed pressure roller 521, the cut hook line 7 can be roll-formed and a hook arm 82 with a curved structure can be formed.

Through the provision of the guide seat 53, the hook line 7 can be further made to enter the welding and cutting mechanism 4 more smoothly and be located directly above the nail line 6, thereby facilitating the subsequent smooth welding and fixing of one end of the hook line 7 to the nail line 6.

[0051] like Figures 1 to 12As shown, the processing method of the automatic production equipment for hook nails adopts any one of the automatic production equipment for hook nails and the processing method thereof, including the following steps:

[0052] Step 1: The nail wire 6 is fed horizontally under the intermittent transmission of the feeding device 12 of the nail making machine body 1, and the hook wire 7 is fed vertically under the intermittent transmission of the automatic feeder 2. Specifically, the left transmission shaft 141 can drive the feeding transmission shaft 224 to rotate through the meshing transmission of the bevel gear assembly 225, thereby driving the rotation of the eccentric disk 221, and driving the swing arm 223 to swing through the connecting rod 222, so that the feeding box 21 can intermittently feed the hook wire 7 as the nail making machine body 1 works;

[0053] Step 2: The hook wire 7 passes through the bending and steering mechanism 3 and enters the welding and cutting mechanism 4 in an inclined direction opposite to the conveying direction of the nail wire 6. Specifically, the hook wire 7 can pass through the bending channel 35 between the plurality of first pressing wheels 33 and the plurality of second pressing wheels 34. Since the bending channel 35 is provided with a first straight line segment 351, an arc segment 352 and a second straight line segment 353 from top to bottom, the hook wire 7 can be corrected and the conveying direction of the hook wire 7 can be changed, so that the hook wire 7 can enter the welding and cutting mechanism 4 better.

[0054] Step 3: The welding assembly 41 welds and fixes one end of the hook wire 7 to the nail wire 6, and at the same time, the cutting assembly 42 also cuts the hook wire 7. Specifically, when the right transmission shaft 142 rotates, the first push rod 4331 can be pushed up by the first cam 431. Through the lever principle, at this time, the welding push rod 4332 and the cutting push rod 4333 can be flipped downward, thereby driving the welding slide 415 and the cutting slide 422 to move downward at the same time. When the welding slide 415 moves downward, it can drive the upper copper rod 411 to move downward, thereby fixing and welding one end of the hook wire 7 to the nail wire 6. When the cutting slide 422 moves downward, , which can drive the cutter 421 to move downward, thereby cutting the hook wire 7. The welding and cutting of the hook wire 7 are performed simultaneously. After the welding and cutting of the hook wire 7 are completed, as the right transmission shaft 142 continues to rotate, the first cam 431 no longer pushes the first push rod 4331 upward. At this time, the welding reset spring 417 can drive the welding slide 415 to move upward and drive the upper copper rod 411 to move upward away from the lower copper rod 413 for rapid reset, so as to facilitate the next welding. The cutting reset spring 425 can drive the cutting slide 422 to move upward and drive the cutter 421 to move upward away from the hook wire 7 for rapid reset, so as to facilitate the next cutting.

[0055] Step 4: The rolling forming assembly 52 rolls the cut hook line 7 to form a hook arm 82 with a curved structure. Specifically, when the right transmission shaft 142 rotates, the second cam 511 can push the second push rod 5131 downward. Through the lever principle, the rolling lifting rod 5132 can flip upward at this time, thereby driving the rolling slide 524 to move upward. When the rolling slide 524 moves upward, it can drive the movable pressure roller 522 to move upward along the guide groove 5261 of the guide rail 526, so that the cut hook line 7 can be moved upward with the cooperation of the fixed pressure roller 521. The hook wire 7 is roll-formed and forms a hook arm 82 with a curved structure. Then, before the movable pressure roller 522 moves downward to reset, the hook arm 82 welded and fixed on the nail wire 6 is separated from the fixed pressure roller 521 as the nail wire 6 is intermittently conveyed. As the right transmission shaft 142 continues to rotate, the second cam 511 no longer pushes the second push rod 5131 downward. At this time, the rolling reset spring 527 can drive the rolling slide 524 to move downward and drive the movable pressure roller 522 away from the fixed pressure roller 521 for rapid reset, so as to facilitate the next rolling forming.

[0056] Step 5: The hook arm 82 welded and fixed on the nail line 6 passes through the entry hole 111 along with the nail line 6, and the clamping die device 13 on the nail making machine body 1 can clamp the nail line 6, and punch out the nail head at the head of the nail line 6 through the cooperation of the punch device 16 on the nail making machine body 1;

[0057] Step 6: The nail line 6 punched out with the nail head continues to be transmitted forward, and then the nail line 6 is cut by the cutting device 18 on the nail making machine body 1 to form a nail body 81;

[0058] Step 7: The formed hook nails 8 will fall directly downward and be collected, and steps 1 to 6 are repeated to achieve continuous automatic production of hook nails 8.

[0059] The above are only some specific implementation methods of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
