Description

Technical Field

[0001] This utility model relates to the field of nail making machine technology, and in particular to a dual-line high-speed nail making machine. Background Technology

[0002] In modern industrial production, nail-making machines, as crucial equipment in metal processing, are widely used in various industries such as construction and furniture manufacturing. Most existing nail-making machines employ a single-wire production model. The process typically involves: first, straightening the steel wire using a straightening structure to eliminate bending deformations during transportation or storage, ensuring the wire meets the required straightness for nail making; then, cutting the straightened wire to a predetermined length using a cutting mechanism; and finally, nail-making by a nail-making mechanism to produce the finished nail. However, this single-line production model has significant limitations. Processing only one wire at a time results in extremely low production efficiency, making it difficult to meet the ever-increasing market demand. In large-scale production scenarios, single-line nail-making machines require substantial investment in equipment and manpower, leading to a significant increase in production costs and severely compressing profit margins. With increasingly fierce market competition, improving the production efficiency of nail-making machines and reducing production costs have become critical issues that the industry urgently needs to address.

[0003] Therefore, those skilled in the art have provided a dual-line high-speed nail-making machine to solve the problems mentioned in the background art. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1-6 An embodiment of this utility model is provided: a dual-line high-speed nail making machine, including a lower support platform 4, a nail making mechanism 1 fixedly installed at the upper end of the lower support platform 4 near the rear side, a feeding mechanism 2 fixedly installed at the upper end of the lower support platform 4 near the front side, a side protective frame 5 fixedly installed on the side of the lower support platform 4 near the feeding mechanism 2, a heat dissipation window 6 provided at the opening of the side protective frame 5 near the feeding mechanism 2, and a straightening mechanism 3 fixedly installed on the outside of the side protective frame 5 near the feeding mechanism 2;

[0029] Specifically, the lower support platform 4, as the basic load-bearing component of the entire machine, is made of high-strength steel and has a load-bearing capacity of up to 500 kg, ensuring the stability of the nail-making machine during operation. The side protective frame 5 not only effectively prevents operators from accidentally contacting moving parts, ensuring personal safety, but also promotes air circulation through the heat dissipation window 6. The ventilation area of ​​the heat dissipation window 6 is designed to be 0.2㎡, which can keep the internal temperature of the nail-making machine below 60℃, avoiding the impact of excessive temperature on equipment performance and service life. The straightening mechanism 3, feeding mechanism 2, and nail-making mechanism 1 are arranged sequentially to form a continuous nail-making production line, realizing an automated process from raw material straightening and feeding to nail making. The reasonable layout design allows each mechanism to work together compactly, reducing the equipment's footprint by 30% compared to traditional decentralized nail-making equipment. The integrated production line design improves the continuity and stability of production, reduces manual intervention, reduces material loss during transportation, and improves overall production efficiency.

[0030] Reference Figure 3 and 4 The nail-making mechanism 1 includes a drive platform 101. Five limit pulleys 103 are rotatably arranged at the front end of the drive platform 101 near the upper and lower ends. The limit pulleys 103 are grouped into sets of five. A transmission steel belt 112 is connected between the two sets of limit pulleys 103. The outer surface of the transmission steel belt 112 has multiple transmission grooves. The inner diameter of the multiple transmission grooves is 0.5mm larger than the radius of the raw material, which can ensure the smooth placement of the raw material and prevent the raw material from shaking. Two power pulleys 102 are rotatably arranged at the front end of the drive platform 101 near one side. The rear ends of the two power pulleys 102 are respectively connected to the output ends of two 5kW motors inside the drive platform 101. The two power pulleys 102 mesh with the transmission grooves on the outer surface of the two transmission steel belts 112. When the power pulleys 102 rotate, they can drive the transmission steel belts 112 to rotate around the limit pulleys 103.

[0031] A nail cutting table 104 and a nail head making table 109 are fixedly installed on both sides of the front end of the drive table 101. Two intermediate limit frames 108 are fixedly installed at the middle position of the front end of the nail cutting table 104 and the nail head making table 109. Two transmission steel belts 112 are slidably installed inside the two intermediate limit frames 108. Two nail cutting sliders 105 are slidably installed at the upper and lower ends inside the nail cutting table 104. Each of the multiple nail cutting sliders 105 is equipped with a tool clamp 106. Each of the multiple tool clamps 106 is equipped with a nail cutting tool 107. The multiple nail cutting sliders 105, tool clamps 106 and nail cutting tools 107 are arranged in pairs in the vertical direction. The two sets of nail cutting sliders 105 are respectively connected to a vertical push rod with a stroke of 50mm inside the nail cutting table 104. The two sets of nail cutting sliders 105 can cut two raw materials at the same time.

[0032] Two nail head clamps 110 are slidably installed at the upper and lower ends of the nail head making table 109. Two impact structures 111 are installed at the front end of the nail head making table 109. The two impact structures 111 are pressed against the nail head part by the internal telescopic mold to form the nail head structure.

[0033] A feeding frame 7 is fixedly installed inside the opening of the side protective frame 5 near the nail-making mechanism 1. The feeding frame 7 is located at the end of one side of the two conveyor steel belts 112.

[0034] Specifically, two motors within the drive table 101 drive the transmission steel belt 112 at a speed of 150 r / min via power pulleys 102. A limiting system composed of five limiting pulleys 103 controls the running error of the transmission steel belt 112 within ±0.2 mm, ensuring the accuracy of material transmission. The intermediate limiting frame 108 further guides and limits the transmission steel belt 112, preventing it from deviating. A vertical push rod within the nail cutting table 104 pushes the nail cutting slider 105, driving the nail cutting blade 107 to cut the material at a frequency of 100 times / minute. The blade is made of high-speed steel with a hardness of HRC62-65, ensuring cutting accuracy and efficiency. The impact structure 111 of the nail head making table 109 is hydraulically driven, applying pressure up to 50 MPa, allowing the telescopic die to quickly stamp the end of the material, forming a standard nail head. The nail head clamp 110 securely holds the material, ensuring the quality of the nail head forming. The feeding frame 7 is tilted at 30° to facilitate the smooth sliding and collection of finished nails. The dual-line transmission and synchronous cutting and nail-making design doubles the nail-making efficiency compared to traditional equipment. The high-precision transmission and processing system controls nail dimensional errors to within ±0.1mm, significantly improving product quality. The stable processing reduces wear on tools and molds, extends the service life of equipment components, and lowers maintenance costs.

[0035] Reference Figure 5 The feeding mechanism 2 includes an inner support frame 206, inside which a drive motor 207 is installed. An eccentric wheel 205 is rotatably installed on one side of the inner support frame 206. A connecting frame 204 is rotatably installed on one end of the eccentric wheel 205, and a sliding table 203 is rotatably installed on the other end of the connecting frame 204. The slide rail of the sliding table 203 is fixedly connected to the inner support frame 206. Two feeding blocks 202 are fixedly installed on the slider of the sliding table 203. Two auxiliary limiting blocks 201 are fixedly installed on one side of the sliding table 203. The horizontal positions of the two auxiliary limiting blocks 201 and the feeding blocks 202 are the same as the gap height between the two transmission steel belts 112. A feeding motor 209 is installed at the lower end of the inner support frame 206. An adjusting handwheel 208 is installed at the output end of the feeding motor 209. The output end of the feeding motor 209 is connected to the eccentric wheel 205 through the adjusting handwheel 208, a pulley, and a belt.

[0036] Specifically, the feeding motor 209 has a power of 2kW, and the feeding speed can be flexibly adjusted within the range of 0-2m / min by adjusting the handwheel 208. The feeding motor 209 drives the eccentric wheel 205 to rotate at a speed of 60r / min, and the circular motion is converted into the linear reciprocating motion of the sliding table 203 through the connecting frame 204. The stroke of the sliding table 203 is 100mm. The feeding block 202 and the auxiliary limit block 201 work together to accurately push two raw materials with a diameter in the range of 1-5mm each time, accurately feeding the raw materials into the gap of the transmission steel belt 112, ensuring the stability and accuracy of feeding. The adjustable feeding speed design allows the nail making machine to adapt to different specifications of raw materials and production needs, improving the versatility of the equipment. The transmission structure of the eccentric wheel 205 is simple and reliable, reducing the probability of mechanical failure. Precise feeding control avoids the accumulation and blockage of raw materials, ensuring the continuity of production.

[0037] Reference Figure 6 The straightening mechanism 3 includes a vertical support plate 302, with multiple horizontal straightening wheels 301 rotatably arranged on both sides inside the vertical support plate 302, a lower support plate 304 fixedly arranged at the front end of the vertical support plate 302, multiple vertical straightening wheels 303 rotatably arranged on both sides of the upper end of the lower support plate 304, and a feed plate 305 fixedly arranged at the front end of the lower support plate 304.

[0038] Specifically, both the horizontal straightening wheel 301 and the vertical straightening wheel 303 are polyurethane-coated with a Shore A hardness of 80, effectively straightening the raw material while preventing scratches on its surface. When the raw material passes through the straightening mechanism 3, the compression action of the horizontal and vertical straightening wheels 303 effectively straightens steel wires with a maximum bending angle of 15°, achieving a straightness of less than 0.5 mm / m, meeting the requirements of the nail-making process. The feed plate 305 has a 10° inclination angle, facilitating the smooth sliding of the raw material into the straightening mechanism 3. The combined design of multiple sets of horizontal and vertical straightening wheels 303 enables efficient straightening of raw materials with varying degrees of curvature, achieving a success rate of over 99%. The polyurethane-coated straightening wheels reduce surface damage to the raw material, improving product qualification rates. The stable straightening effect provides a high-quality raw material foundation for subsequent nail-making processes, ensuring the stability of nail quality.

[0039] Working principle: During operation, two steel wires to be processed first enter the straightening mechanism 3. Multiple horizontal straightening wheels 301 and vertical straightening wheels 303 in the straightening mechanism 3 work together to straighten the steel wires in the horizontal and vertical directions, respectively, eliminating the bending deformation of the steel wires and making them meet the straightness standard required for nail making. After straightening, the two steel wires enter the feeding mechanism 2. The output end of the feeding motor 209 drives the eccentric wheel 205 to rotate through the adjustment handwheel 208, pulley and belt. The eccentric wheel 205 drives the connecting frame 204 to move, which in turn makes the sliding table 203 reciprocate linearly on the slide rail. The two feeding blocks 202 and two auxiliary limit blocks 201 on the sliding table 203 push the two steel wires synchronously to the nail making mechanism 1.

[0040] In the nail-making mechanism 1, two motors inside the drive platform 101 drive two power pulleys 102 to rotate. The power pulleys 102 mesh with the transmission grooves on the outer surface of the transmission steel belt 112, causing the transmission steel belt 112 to rotate around the limiting pulley 103. Two steel wires are precisely placed in the gap between the two transmission steel belts 112 and are conveyed forward with the movement of the transmission steel belts 112. When the steel wires are conveyed to the nail-cutting platform 104, two sets of vertical push rods inside the nail-cutting platform 104 simultaneously push the nail-cutting slider 105 downward, and the nail-cutting cutter 107 installed in the cutter clamp 106 cuts the two steel wires simultaneously. The cut steel wires are confined in the transmission grooves of the transmission steel belt 112 and continue to be conveyed forward with the transmission steel belt 112 to the nail head making platform 109. At the nail head making platform 109, two impact structures 111 apply pressure to the ends of the steel wires through internal telescopic molds to stamp and form the nail head structure. Finally, the finished nails are transported to the unloading frame 7 by the conveyor belt 112, completing the entire double-line nail making process.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
