That is, unless stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.

[0018] According to Figures 1-6As shown, the double cap nail forming device comprises a conveying device 1, a shearing device 2 and a nail cap forming device 3, the shearing device 2 and the nail cap forming device 3 are arranged side by side, and the conveying device 1 is arranged between the shearing device 2 and the nail cap forming device 3, the shearing device 2 is used for shearing a continuous iron wire into a plurality of nail segments, and the conveying device 1 is used for conveying the nails formed after shearing to the nail cap forming device 3 for nail cap forming work; the nail cap forming device 3 comprises a clamping die device 4 and a punch device 5, the clamping die device 4 comprises an upper clamping die frame 41 and a lower clamping die frame 42, the tail ends of the upper clamping die frame 41 and the lower clamping die frame 42 are provided with rollers 48, the rollers 48 are provided with a cam 6 therebetween, the rollers 48 are used for rotating to reduce the friction with the cam 6, the cam 6 is arranged on a through shaft, the through shaft is driven to rotate to drive the cam 6 to rotate, so that the upper clamping die frame 41 and the lower clamping die frame 42 can be continuously opened and closed to control the opening and closing of the upper die seat 43 and the lower die seat 44 for clamping action, the upper die seat 43 and the lower die seat 44 are arranged on the upper clamping die frame 41 and the lower clamping die frame 42 respectively, the upper die seat 43 and the lower die seat 44 can be replaced according to the specifications of the nails, and the adaptability of the device is enhanced, a pair of clamping bodies 45 are arranged on the upper die seat 43 and the lower die seat 44, the clamping bodies 45 are used for clamping the nails, and the clamping bodies 45 between the upper die seat 43 and the lower die seat 44 cooperate to form a first clamping groove 46 and a second clamping groove 47 for clamping the nails; the punch device 5 comprises a slide rod seat 51, the slide rod seat 51 is provided with a slide rod 52, the slide rod 52 drives the punch device 5 to complete the stamping action under the action of a driving device, one end of the slide rod 52 opposite to the clamping die device 4 is provided with a punch seat 53, a fixed plate is further arranged on the punch seat 53, a first punch 54 and a second punch 55 are arranged on the punch seat 53 through the fixed plate, the first punch 54 and the second punch 55 are opposite to the first clamping groove 46 and the second clamping groove 47 respectively, a punch hole 56 with a diameter slightly larger than that of the nail is further arranged in the first punch 54, and the diameter of the punch hole 56 is slightly larger than that of the nail so that the nail can enter the punch hole 56 for stamping and then be ejected.

[0019] A first ejector 57 is arranged on one side of the first punch 54 of the punch seat 53, and the first ejector 57 is used for arranging and aligning the nail to be clamped by the first clamping groove 46, a second ejector 58 is arranged between the first punch 54 and the second punch 55, and the second ejector 58 is used for adjusting the position of the nail so that the nail cap is inside the second clamping groove 47 when the second clamping groove 47 clamps the nail.

[0020] The first punch 54 is provided with a gas hole 59 communicating with the punching hole 56, and iron filings are left on the tail of the nail after shearing, and the iron filings are left in the punching hole 56 after punching. The gas hole 59 is connected with an external air jet device, and the punching hole 56 is jetted after each punching to spray the iron filings out and keep the punching hole 56 clean.

[0021] In practical use, a continuous iron wire is sheared into segments of nails by the shearing device 2, and then the nails are transported to the nail cap forming device 3 by the conveying device 1 for processing. In the processing process, a nail passes through the first top head 57 first to be aligned to adjust the length of the nail remaining at the tail end after being clamped, and then the nail passes through the first clamping groove 46 to be clamped. At this time, the punch device 5 is pushed out, the tail of the nail is inserted into the punching hole 56 on the first punch 54, and the length of the nail remaining at the tail end is greater than the depth of the punching hole 56. Thus, after the punch device 5 completes the punching, the first nail cap is formed between the outside of the first clamping groove 46 and the first punch 54. The nail cap is formed in the middle of the nail. Next, the nail continues to move and passes through the second top head 58. The second top head 58 pushes the nail inward to ensure that the first nail cap is located on the inside of the clamping die body 45 when the nail enters the second clamping groove 47. When passing through the second clamping groove 47, the remaining tail end of the nail is clamped again and processed by the second punch 55 to form the second nail cap at the tail end of the nail, completing the processing of the double-cap nail. In the working process, the conveying device 1 continuously conveys the nails, and the upper clamping die frame 41 and the lower clamping die frame 42 are continuously opened and closed by the driving cam 6 to allow the clamping die device 4 to clamp the passing nails. At the same time that the nails are clamped, the punch device 5 performs the punching work. In one punching process, the punch device 5 completes multiple steps. First, the first top head 57 aligns the nail to be clamped to ensure the correct position of the nail. Then, the nail clamped by the first clamping groove 46 is punched by the first punch 54 to complete the first nail cap. Then, the second top head 58 pushes the nail with the formed first nail cap to adjust the position of the nail. Finally, the nail clamped by the second clamping groove 47 is formed by the second punch 55 to complete the formation of the second nail cap.

[0022] The design scheme is ingenious. By cooperating the clamping die device and the punch device, alignment, first nail cap punching, nail position adjustment, and second nail cap punching can be completed at the same time in one punching process. The operation process is simplified. The continuous and compact working process significantly improves the production efficiency and greatly reduces the production time and cost. The double-cap nail formed by twice punching can ensure the high quality and consistency of each nail cap, meeting the market demand for high-quality double-cap nail products.

[0023] The present application is not limited to the foregoing specific embodiments. The present application extends to any new feature or combination of features disclosed in this specification, as well as any new method or process disclosed in this specification or any new combination of steps of the disclosed methods or processes.
