[0001] The present invention relates to a nail making machine and, more particularly, to a nail making machine for manufacturing nails automatically.
[0002] In fabrication of a nail, a metallic wire is stamped by a stamping machine to form a semi-manufactured nail with an enlarged head. Then, the semi-manufactured nail is cut by a cutting tool to have a shank and a tip so as to produce a nail with the head, shank and tip. However, the nail is produced and worked by the stamping machine and the cutting tool respectively which are situated at different places, so that the nail has a complicated working process and a longer working time, thereby increasing the costs of fabrication. In addition, the nail is mixed with the iron chips of the metallic wire so that it is necessary to separate the nail from the iron chips of the metallic wire, thereby causing inconvenience to the operator, and thereby greatly increasing the time of production.
[0003] In accordance with the present invention, there is provided a nail making machine, comprising a trimming device to trim a metallic wire, a cutting tool located beside the trimming device to cut the metallic wire from the trimming device into a plurality of semi-manufactured nails, a receiving device located beside the cutting tool to receive and arrange the semi-manufactured nails from the cutting tool, a rotation disk located under the receiving device to receive and move the semi-manufactured nails from the receiving device, and a stamping device located at a side of the rotation disk to stamp the semi-manufactured nails on the rotation disk so as to form a plurality of nail products.
[0004] The primary objective of the present invention is to provide a nail making machine that comprises a trimming device to trim the metallic wire, a cutting tool to cut the metallic wire into the semi-manufactured nails, a receiving device to receive and arrange the semi-manufactured nails, a rotation disk to move the semi-manufactured nails, a stamping device to stamp the semi-manufactured nails so as to form the nail products, and a transmission device to control operation of the cutting tool, the rotation disk and the stamping device, so that the nail making machine is operated automatically, thereby enhancing the working efficiency of the nail making machine and enhancing the quality of the nail products.
[0005] Another objective of the present invention is to provide a nail making machine, wherein the nail making machine is mounted on the working table, and all of the working procedures of the nail products are finished on the working table, thereby decreasing the costs of fabrication.
[0006] A further objective of the present invention is to provide a nail making machine, wherein the operation handle of the receiving device is operated to allow or stop entrance of the semi-manufactured nails from the receiving channel of the receiving rack into the rotation disk, and the oblique storage tray can temporarily store the semi-manufactured nails falling from the receiving channel of the receiving rack, so that the semi-manufactured nails are introduced into the rotation disk smoothly.
[0007] A further objective of the present invention is to provide a nail making machine, wherein the rotation disk is sandwiched and clamped between the two clamping seats, the stop block and the stamping device and is kept stationary during operation of the stamping device, thereby facilitating the working efficiency of the stamping device and enhancing the quality of the nail products.

[0020] In operation, again referring to Figs. 1-17, the metallic wire is trimmed into a flat sheet plate by the transverse rollers 10 and the longitudinal rollers 20 of the trimming device 2. Then, the metallic wire is delivered and guided through the two delivery wheels 31 and the guide hole 34 of the guide member 33 of the delivery device 30 into the cutting tool 40. Then, the two sliding bases 41 of the cutting tool 40 are driven by the two driven shafts 96 of the transmission device 90 to move toward each other to cut the metallic wire into a plurality of semi-manufactured nails 3 by the cutting blades 43 of the two sliding bases 41. At this time, the semi-manufactured nails 3 are separated from the waste chips of the metallic wire, and the waste chips of the metallic wire fall down into a waste container 45 which is mounted in the working table 1. Then, the conveyor wheels 50 convey the semi-manufactured nails 3 from the cutting tool 40 to the receiving device 60. Then, the semi-manufactured nails 3 are in turn introduced through the receiving channel 61 of the receiving rack 68 of the receiving device 60 into the holding seats 71 of the rotation disk 70. Then, each of the semi-manufactured nails 3 is in turn moved to align with the stamping device 80 by rotation of the rotation disk 70. Then, each of the two clamping seats 75 is moved to press and clamp the rotation disk 70, and the stop block 76 located opposite to the stamping device 80 is moved to press the rotation disk 70 so that the rotation disk 70 is sandwiched and clamped between the two clamping seats 75, the stop block 76 and the stamping device 80 and is kept stationary during operation of the stamping device 80. At this time, the clamping groove 751 of one of the two clamping seats 75 is moved to align with the first groove 72 and the second groove 73 of the respective holding seat 71 of the rotation disk 70 to press and clamp the respective semi-manufactured nail 3, so that each of the semi-manufactured nails 3 is clamped and positioned between the first groove 72 and the second groove 73 of the respective holding seat 71 of the rotation disk 70 and the clamping groove 751 of the respective clamping seat 75. Finally, the stamping head 81 of the stamping device 80 is moved to stamp each of the semi-manufactured nails 3 so as to a plurality of nail products. Then, each of the nail products is moved forward by rotation of the rotation disk 70 and falls down into a product container 82 which is mounted in the working table 1.
[0021] Accordingly, the nail making machine comprises a trimming device 2 to trim the metallic wire, a cutting tool 40 to cut the metallic wire into the semi-manufactured nails 3, a receiving device 60 to receive and arrange the semi-manufactured nails 3, a rotation disk 70 to move the semi-manufactured nails 3, a stamping device 80 to stamp the semi-manufactured nails 3 so as to form the nail products, and a transmission device 90 to control operation of the cutting tool 40, the rotation disk 70 and the stamping device 80, so that the nail making machine is operated automatically, thereby enhancing the working efficiency of the nail making machine and enhancing the quality of the nail products. In addition, the nail making machine is mounted on the working table 1, and all of the working procedures of the nail products are finished on the working table 1, thereby decreasing the costs of fabrication. Further, the operation handle 66 of the receiving device 60 is operated to allow or stop entrance of the semi-manufactured nails 3 from the receiving channel 61 of the receiving rack 68 into the rotation disk 70, and the oblique storage tray 64 can temporarily store the semi-manufactured nails 3 falling from the receiving channel 61 of the receiving rack 68, so that the semi-manufactured nails 3 are introduced into the rotation disk 70 smoothly. Further, the rotation disk 70 is sandwiched and clamped between the two clamping seats 75, the stop block 76 and the stamping device 80 and is kept stationary during operation of the stamping device 80, thereby facilitating the working efficiency of the stamping device 80 and enhancing the quality of the nail products.
