[0019] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention.

[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] Reference Figure 1 to Figure 12 A cold heading and tapping integrated machine for nut production is proposed, which is used to process rods into nuts, including a frame 1; a cold heading piece 2 is arranged on the frame 1, and the cold heading piece 2 has a first feed port 210 and a first discharge port 220, and the rod enters the cold heading piece 2 through the first feed port 210; a tapping piece 3 is arranged on the frame 1, and the tapping piece 3 has a second feed port 310 and a second discharge port 320, and the first discharge port 220 is connected to the second feed port 310, and the tapping piece 3 is used to tap the blank processed by the cold heading piece 2.

[0023] In this embodiment, when producing nuts, the bar material is fed into the first feed port 210, and the cold heading part 2 processes the bar material. As the cold heading part 2 processes the bar material, the bar material gradually deforms and eventually becomes a nut blank, and leaves the cold heading part 2 from the first discharge port 220. The processing of the cold heading machine is a continuous processing, so the nut blank that is first processed will be gradually pushed forward by the workpiece that is subsequently processed, and eventually leaves the cold heading part 2 from the first discharge port 220 and enters the tapping part 3. After the nut blank enters the second feed port 310 from the first discharge port 220, it will be tapped by the tapping part 3, and leave the tapping part 3 after the tapping is completed, so that the nut processing is completed. The frame 1 provides a stable installation foundation for the cold heading part 2 and the tapping part 3, ensuring that the entire integrated machine maintains structural stability during operation and reduces vibration and error. The cold heading part 2 is arranged on the frame 1, which can realize the cold heading of the bar. The integrated design avoids the transfer of workpieces between different equipment, reduces the intermediate links, and reduces the risk of damage and deformation of the workpiece. The first feed port 210 and the first discharge port 220 of the cold heading part 2 are arranged so that the feeding of the bar and the discharge of the blank after cold heading are carried out in an orderly manner, thereby improving the continuity of the production process. The tapping part 3 is also arranged on the frame 1, and is closely matched with the cold heading part 2. The blank after cold heading can directly enter the second feed port 310 from the first discharge port 220 for tapping, without the need for additional handling and positioning operations, thereby greatly improving the production efficiency. The design of the second feed port 310 and the second discharge port 320 of the tapping part 3 ensures smooth feeding and discharging of the tapping process, which helps to achieve continuous production. Cold heading and tapping are completed on the same equipment, thereby avoiding the problem of inaccurate positioning caused by equipment switching and workpiece transfer, and improving the processing accuracy and quality stability of the product.

[0024] As a further technical solution, the cold heading part 2 includes a sliding frame 230 slidably set on the frame body 1, and the sliding frame 230 has a plurality of punching needles 240; there are a plurality of mold shells 250, and the plurality of mold shells 250 are arranged in an array and spaced apart on the frame body 1. After the sliding frame 230 slides, the punching needle 240 approaches or moves away from the mold shell 250, and the punching needle 240 is used to gradually extrude the rod and form the rod; a demolding needle 260 is slidably set in the mold shell 250, and one end of the demolding needle 260 is located in the mold shell 250, and the other end passes through the mold shell 250. After the demolding needle 260 slides, one end located in the mold shell 250 enters or leaves the mold shell 250, and the demolding needle 260 is used to send out the rod in the mold shell 250; a limit block 261 is set on the demolding needle 260, and the limit block 261 is used to limit the moving distance of the demolding needle 260.

[0025] In this embodiment, the mold shell 250 is used to gradually shape the bar into a nut blank. The shapes of the multiple mold shells 250 are different and gradually formed. When the bar enters the cold forging part and reaches the specified position, the sliding frame 230 will slide, and the punch 240 on the sliding frame 230 will press the bar into one of the mold shells 250 and apply pressure to deform the bar. After the extrusion is completed, the sliding frame 230 will drive the punch 240 to separate from the mold shell 250. At this time, the demoulding pin 260 will slide and eject the blank located deep in the mold shell 250, so that it will be separated from the mold shell 250. Then the blank will continue to slide to another mold shell 250 to repeat the molding, and finally reach the first discharge port 220 to be ejected, and then leave the cold forging part 2. The sliding frame 230 is slidably arranged on the frame body 1, so that the punch 240 can flexibly approach or move away from the mold shell 250, which is convenient for controlling the cold forging process and adapting to the cold forging requirements of nuts of different specifications. The combination of multiple punches 240 and multiple mold shells 250 can gradually perform precise extrusion molding on the rod, improve the accuracy and quality of cold heading, and reduce material waste. The demoulding pin 260 is slidably arranged in the mold shell 250, and can smoothly push the molded rod out of the mold shell 250 after the cold heading is completed, so as to realize automatic demoulding and improve production efficiency. One end of the demoulding pin 260 penetrates the mold shell 250, and the moving distance is limited by the limit block 261, so as to ensure that the movement of the demoulding pin 260 is accurate and reliable, and avoid excessive movement or insufficient movement affecting the demoulding process.

[0026] As a further technical solution, it also includes: a feeding rack 110 is slidably set on the frame body 1, and the feeding rack 110 has a feeding hole 111. After the feeding rack 110 slides, the feeding hole 111 is aligned with or canceled with the first feed port 210, and the feeding hole 111 is used to cut the rod; there are a plurality of clamps 120, which are set on the feeding rack 110, and the clamps 120 have transfer holes 121. After the feeding rack 110 slides, the plurality of transfer holes 121 are aligned with or canceled with the mold shell 250, and the sliding direction of the feeding rack 110 is parallel to the direction in which the plurality of mold shells 250 are arranged in an array, and the clamps 120 are used to transport the rod from one mold shell 250 to the next adjacent mold shell 250.

[0027] In this embodiment, when the first feed port 210 is aligned with the feed hole 111, the rod will enter the feed hole 111 from the first feed port 210. When it enters a certain length, the feed rack 110 will move. During the movement, a strong shear force will be generated to cut the rod. After the rod in the feed hole 111 is cut, it will be transported by the feed rack 110 to the inlet of the mold shell 250 for alignment. At this time, the punch 240 will pass through the feed hole 111 when moving to send the cut rod into the mold shell 250 to complete the stamping. After the rod is deformed, the punch 240 leaves the mold shell 250. and the feeding hole 111. At this time, the feeding rack 110 is reset to cut off the next section of the bar. After the feeding rack 110 is reset, the clamp 120 on the feeding rack 110 will be aligned with the mold shell 250. At this time, after the demoulding needle 260 pushes the blank out, the blank will enter the transfer hole 121 on the clamp 120. With the next action of the feeding rack 110, it moves to the next mold shell 250 to punch the next mold shell 250. After repeated multiple times, the blank is formed. The last clamp 120 will align the blank with the first discharge hole, and the punching needle 240 will feed it into the first discharge hole to realize discharge. The feeding rack 110 is slidably set on the frame body 1, so that the feeding hole 111 can be accurately aligned with the first feed port 210 or cancel the alignment, realizing the precise control of the bar feeding, avoiding the disordered feeding of the bar, and improving the accuracy and stability of production. The feeding hole 111 has the function of cutting the rods, and can directly cut the rods to a suitable length during the feeding process, reducing the subsequent processing steps and improving production efficiency. The clamp 120 is set on the feeding rack 110. As the feeding rack 110 slides, the transfer hole 121 can be aligned or unaligned with the mold shell 250, which is convenient for clamping and transferring the rods, and realizes the orderly transfer of the rods between different mold shells 250. The clamp 120 can transport the rods from one mold shell 250 to the next adjacent mold shell 250, realizing continuous production, reducing manual intervention, and reducing labor intensity.

[0028] As a further technical solution, it also includes: the driving shaft 130 is rotatably set on the frame 1; the first eccentric wheel 131 is set on the driving shaft 130, the driving shaft 130 and the first eccentric wheel 131 are eccentrically set, and the first eccentric wheel 131 rotates with the driving shaft 130; the swing seat 140 is rotatably set on the frame 1, when the swing seat 140 rotates, one end of the swing seat 140 approaches or moves away from the demoulding needle 260, and the swing seat 140 is used to drive the demoulding needle 260 to slide; one end of the first transmission rod 150 is sleeved on the first eccentric wheel 131, and the other end is hinged to the swing seat 140, and the first transmission rod 150 is used to drive the swing seat 140 to swing.

[0029] In this embodiment, the driving shaft 130 rotates on the frame 1, and the first eccentric wheel 131 will rotate along with the driving shaft 130 when the driving shaft 130 rotates. When the first eccentric wheel 131 rotates, the first transmission rod 150 sleeved on the first eccentric wheel 131 will move regularly with the rotation of the first eccentric wheel 131. When the first transmission rod 150 moves, it will transmit the action to the swing seat 140, thereby causing the swing seat 140 to swing. After the swing seat 140 swings, it abuts against the demolding needle 260 and drives the demolding needle 260 to move. At the same time, the driving shaft 130 is also used to drive the sliding frame 230 to move through the above-mentioned first eccentric wheel 131 structure. By designing the eccentric position of the first eccentric wheel 131, it can be ensured that when the driving shaft 130 rotates, the sliding frame 230 and the swing frame can achieve regular movements according to the processing sequence, thereby improving the continuity of the processing process.

[0030] As a further technical solution, it also includes: there are a plurality of first conveying wheels 160, which are rotatably set on the frame 1, and the first conveying wheel 160 has a first conveying groove 161; there are a plurality of second conveying wheels 170, which are rotatably set on the frame 1, and the second conveying wheel 170 has a second conveying groove 171, and a conveying space 180 is formed between the first conveying groove 161 and the second conveying groove 171, and the conveying space 180 is used to convey rods.

[0031] In this embodiment, before the rod enters the first feed port 210, it needs to be transported through the first conveying wheel 160 and the second conveying wheel 170. The conveying groove can ensure that the contact area between the rod and the conveying wheel is increased. At the same time, the conveying groove is at the same height as the first feed port 210, which can also prevent the rod from being deformed during transportation, thereby improving the quality of transportation. The first conveying groove 161 on the first conveying wheel 160 and the second conveying groove 171 on the second conveying wheel 170 together form a conveying space 180, which can effectively limit and guide the rod, ensuring that the rod is accurately transported along a predetermined path. The rotating conveying wheel can realize the continuous transportation of the rod, improve the degree of automation and efficiency of production, and reduce manual intervention.

[0032] As a further technical solution, the first conveying wheel 160 has a first gear 162, the second conveying wheel 170 has a second gear 172, the first gear 162 is meshed with the second gear 172, and further includes: a rotating shaft 190 is rotatably disposed on the frame 1, the rotating shaft 190 has a third gear 191, the third gear 191 is meshed with a plurality of first gears 162, and the rotating shaft 190 is used to drive the first conveying wheel 160 to rotate.

[0033] In this embodiment, when the rotating shaft 190 rotates, it can drive the first gear 162 to rotate synchronously, and then the second gear 172 can also rotate to complete the transportation of the rod. The first gear 162 is meshed with the second gear 172, so that the first conveying wheel 160 and the second conveying wheel 170 can achieve synchronous reverse rotation, thereby effectively clamping and conveying the rod, ensuring the stability and accuracy of the transportation. The third gear 191 on the rotating shaft 190 is meshed with a plurality of first gears 162, and the rotation of the rotating shaft 190 can simultaneously drive a plurality of first conveying wheels 160 to rotate, thereby realizing centralized transmission and synchronous control of power and simplifying the transmission structure. This gear transmission method has high transmission efficiency and accuracy, and can ensure the consistency of the rotation speed of the first conveying wheel 160 and the second conveying wheel 170, thereby ensuring the speed and position accuracy of the rod transportation.

[0034] As a further technical solution, the rotating shaft 190 is provided with a ratchet 192, and also includes: a second transmission rod 410 is rotatably set on the frame 1, and one end of the second transmission rod 410 has an arc surface, and the arc surface abuts against the side wall of the second eccentric wheel 132 on the active shaft 130; one end of the first elastic member 420 is set on the second transmission rod 410, and the other end is set on the frame 1, and the first elastic member 420 is used to provide a force for the second transmission rod 410 to approach the active shaft 130; the sliding block 430 is slidably set on the second transmission rod 410; one end of the third transmission rod 440 is rotatably set on the sliding block 430; the swinging sleeve 450 is sleeved on the rotating shaft 190, and the swinging sleeve 450 rotates relative to the rotating shaft 190, and a ratchet 193 is provided on the swinging sleeve 450, and the ratchet 193 is rotatably set on the swinging sleeve 450, and the ratchet 193 cooperates with the ratchet 192, and the swinging sleeve 450 is used to drive the rotating shaft 190 to rotate.

[0035] In this embodiment, when in use, the driving shaft 130 rotates, and the arc surface abuts against the side wall of the second eccentric wheel 132, so the second transmission rod 410 will swing back and forth when the driving shaft 130 rotates. The swing of the second transmission rod 410 will be transmitted to the third transmission rod 440 by the sliding block 430, thereby driving the swing sleeve 450 to swing, and the ratchet 192 mechanism on the rotating shaft 190 will rotate intermittently during the swinging process of the swing sleeve 450, and finally the rotation of the driving shaft 130 will be transmitted to the rotation of the rotating shaft 190. Through the design of its own structure and transmission angle, the feeding speed is matched with the rotation of the driving shaft 130 after multiple adjustments, so as to realize automatic feeding.

[0036] As a further technical solution, the unlocking member 441 is provided on the swing sleeve 450 , and the unlocking member 441 is used to drive the pawl 193 to rotate, and the pawl 193 is moved closer to or away from the ratchet wheel 192 after rotating.

[0037] In this embodiment, the unlocking member 441 and the pawl 193 are connected by an elastic connecting piece. The unlocking member 441 is used to drive the pawl 193 to rise and fall. When the pawl 193 rises, it will leave the ratchet 192. At this time, no matter how the swing sleeve 450 swings, the rotation of the rotating shaft 190 cannot be realized, so that the feeding stops. After the pawl 193 falls, the pawl 193 cooperates with the ratchet 192, and the swing sleeve 450 swings to drive the rotating shaft 190 to rotate. The setting of the unlocking member 441 allows the pawl 193 to flexibly approach or move away from the ratchet 192, which is convenient for stopping or adjusting the rotation of the rotating shaft 190 when necessary, and realizing precise control of the conveying process. When the equipment is abnormal or maintenance is required, the pawl 193 is separated from the ratchet 192 by the unlocking member 441, and the conveying of the bar can be quickly stopped to avoid the expansion of the accident or damage to the equipment.

[0038] Reference Figure 13~Figure 15 As a further technical solution, the tapping part 3 includes: a tapping frame 510 and a second feed port 310 located on the tapping frame 510; a first rotating disk 520 is rotatably arranged on the tapping frame 510; there are a plurality of limiting sleeves 530, which are rotatably arranged on the first rotating disk 520, and a plurality of limiting sleeves 530 are arranged at intervals around the circumference, and a limiting space 540 is provided in the limiting sleeve 530, and the limiting space 540 passes through the limiting sleeve 530. After the first rotating disk 520 rotates, the limiting space 540 is connected with or disconnected from the second feed port 310, and the limiting space 540 is used to accommodate the nut blank; a tap 550 is slidably arranged on the frame body 1, and the tap 550 enters or leaves the limiting space 540 after sliding, and the tap 550 is used to tap the nut blank.

[0039] In this embodiment, the nut blank will intermittently enter the second feed port 310, and the multiple limiting sleeves 530 will rotate with the first rotating disk 520. The tapping frame 510 provides a stable support and installation foundation for the tapping process, ensuring the accuracy and stability of the tapping operation. The rotation setting of the first rotating disk 520 enables the multiple limiting sleeves 530 to be connected with the second feed port 310 in sequence, realizing continuous feeding and tapping, and improving production efficiency. Several limiting sleeves 530 are arranged on the first rotating disk 520 at circumferential intervals, increasing the number of simultaneous processing and improving the production capacity of the equipment. The limiting space 540 in the limiting sleeve 530 can accurately accommodate the nut blank, effectively position and fix it, prevent it from offset during the tapping process, and ensure the accuracy and quality of the tapping. The tap 550 is slidably arranged on the frame 1, and can accurately enter and leave the limiting space 540 for tapping operations, with flexible movements and strong controllability.

[0040] Reference Fig.16As a further technical solution, it also includes: a casing 610 cover is arranged on the frame 1; a cleaning shell 620 is arranged on the frame 1, and the cleaning shell 620 has a cleaning space 630 and an air inlet 640 and an air outlet 650 connected to the cleaning space 630; an electrostatic dust collector 660 is arranged in the cleaning space 630, and the electrostatic dust collector 660 is used to treat oil mist; a photocatalytic component 670 is arranged in the cleaning space 630, and the photocatalytic component 670 is used to decompose other harmful gases in the exhaust gas, and the air inlet 640, the electrostatic dust collector 660, the photocatalytic component 670 and the air outlet 650 are connected in sequence.

[0041] In this embodiment, the cold heading part 2 needs to be continuously lubricated with lubricating oil during use to ensure that the cold heading part 2 will not rust or get stuck during use. When the lubricating oil sticks to the rod, it will vaporize due to extrusion when squeezed by the punch needle 240, resulting in oil mist. The casing 610 can prevent the oil mist from flying into the air. The cleaning shell 620 is located in the electrostatic dust removal part 660 of the cleaning shell 620 and is used to clean the oil mist. The cleaning shell 620 has a cleaning space 630. After the oil mist enters from the air inlet 640, it passes through the electrostatic dust removal part 660 and the photocatalytic part 670 before leaving from the air outlet 650. It can not only ensure that the large oil mist particles in the oil mist are cleaned and settled, but also ensure that other harmful waste gases in the oil mist are treated, and ensure that the gas discharged from the air outlet 650 meets the emission standards.
