Description

Technical Field

[0001] The present invention relates to the technical field of hook nail equipment, and specifically relates to an automatic stamping and forming equipment for hook nails and its use method. Background Art

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

[0003] Generally speaking, the existing processing method of hook nails usually requires three separate processes. A nail making machine is used to process and form the nail body, a punching machine is used to punch and form the hook arm, and then the processed nail body and hook arm are transferred to an automatic hook nail welding machine, where the hook arm is welded and fixed to the nail body through the automatic hook nail welding machine, 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 more and more complex, the number of processing equipment is large, resulting in high equipment investment costs, large equipment floor area, large equipment energy consumption, a large number of workers are required, resulting in relatively high labor costs, and during the production process, the nail body and the hook arm need to be transferred and carried, the labor intensity of workers is large, and the overall production efficiency is low, seriously affecting the economic benefits of the enterprise.

[0014] The using method of the automatic punching and forming equipment for hook nails adopts any one of the above automatic punching and forming equipment for hook nails, and includes the following steps:

[0015] Step 1: The nail wire is fed horizontally and laterally under the intermittent transmission of the feeding device of the nail making machine body. After being turned by the steering wheel, the hook wire enters between multiple straightening wheels for straightening and is fed vertically downward under the intermittent transmission of the automatic feeder.

[0016] Step 2: The intermittently downwardly transmitted hook wire passes through the guiding channel on the guiding seat and enters the wire inlet channel of the punching seat.

[0017] Step 3: The punching rod moves towards the punching seat side driven by the punch, and the punching rod is inserted into the punching hole of the punching seat, so as to punch a connecting hole on the hook wire.

[0018] Step 4: The hook wire with the connecting hole punched continues to be intermittently transmitted downward.

[0019] Step 5: The male die moves towards the female die side driven by the punch. The cutting head on the male die can cut off the hook wire, and the arc-shaped concave part on the male die can punch the cut hook wire into a bent hook arm in cooperation with the arc-shaped convex part on the female die. At the same time, the punching rod in the second die cavity on the male die can punch the end of the nail wire into a nail head in cooperation with the clamping of the nail wire by the clamping die device and rivet and fix the hook arm on the nail wire.

[0020] Step 6: The nail head is stamped out, and the nail wire riveted with the hook arm continues to be conveyed forward. Then, the nail wire is cut by the cutting device on the nail making machine body to form a nail body, and finally a hook nail composed of the nail body and the hook arm is formed;

[0021] Step 7: The formed hook nails quickly fall downward under the action of the material slapping of the slapper and are collected. Steps 1 to 6 are repeated to realize the continuous automatic stamping and forming of the hook nails.

[0022] As can be seen from the above description, the overall structure of the automatic stamping and forming equipment for hook nails provided by the present invention is novel, practical and reliable. On the basis that the existing nail making machine body can produce nail bodies, an inlet line for the hook wire can be further set, and the hook wire is arranged directly above the nail wire. Through the setting of the automatic feeder, it is convenient to intermittently convey the hook wire, so as to form a double-line feeding with the nail wire, so as to be processed into the hook arm and the nail body on the hook nail respectively in the follow-up; through the setting of the punching mechanism, a connection hole is processed on the hook wire in advance, so that the end of the nail wire can pass through the connection hole and then the end of the nail wire is stamped and formed, so as to facilitate the more stable riveting and fixing of the hook arm on the nail wire; through the setting of the stamping and forming die, the male die is driven by the punch to stamp towards the female die side, and with the cooperation of the clamping die device, only through one stamping and forming, the hook wire can be cut, the cut hook wire can be stamped into a hook arm, and the end of the nail wire can be stamped into a nail head and the hook arm can be riveted and fixed on the nail wire. Then, the nail wire is cut by the cutting device to form a nail body, so that finally a hook nail including a hook arm and a nail body can be formed. The hook nail can stably fix the hook arm on the nail body without welding as a whole. The firmness of the hook nail after processing is good, and it is not easy to crack and loosen between the hook arm and the nail body, effectively ensuring the finished product quality of the hook nail, greatly simplifying the processing and manufacturing process of the hook nail, with simple processes. Compared with the existing production method of hook nails, it greatly improves the production efficiency of hook nails, reduces the number of hook nail production equipment used, thus greatly reducing the overall floor area of the production equipment, and at the same time can greatly reduce the equipment input cost, equipment energy consumption and labor cost, bringing better economic benefits to the enterprise. During the production process, the handling of materials can be greatly reduced, the whole production process is more relaxed and labor-saving, and at the same time the labor intensity of the operators is reduced.

Detailed implementation manners

[0040] The present invention will be further described below through specific implementation manners.

[0041] As Figures 1 to 16As shown in the figure, the automatic stamping and forming equipment for hook nails of the present invention includes a nail making machine body 1. The nail making machine body 1 includes a machine base 11, a punch device 16, a feeding device 12, a straightening device 17, a clamping die device 13, a cutting device 18, a driving device 15, a main transmission shaft, a left transmission shaft 14 and a right transmission shaft. Since the nail making machine body 1 is an existing device, the specific structures and connection relationships of its various components will not be elaborated here. An automatic feeder 2, a punching mechanism 3 and a stamping and forming die 4 are further arranged on the nail making machine body 1 from top to bottom in sequence. The automatic feeder 2 is arranged on the machine base 11 of the nail making machine body 1. The automatic feeder 2 is used for intermittently vertically downward conveying a hook wire 92 located directly above a nail wire 91. The punching mechanism 3 is used for punching a connection hole in the hook wire 92 through which the nail wire 91 can pass. The stamping and forming die 4 includes a male die 41 and a female die 42. The male die 41 is fixedly arranged on a punch head 161 of the punch device 16 of the nail making machine body 1. The female die 42 is fixedly arranged on a clamping die seat 131 of the clamping die device 13 of the nail making machine body 1. When the hook wire 92 enters between the male die 41 and the female die 42 and the end of the nail wire 91 passes through the connection hole, the male die 41 can cut off the hook wire 92 and stamp the cut hook wire 92 into a bent hook arm 932 in cooperation with the female die 42. At the same time, the male die 41 can stamp the end of the nail wire 91 into a nail head 933 in cooperation with the clamping die device 13 and rivet and fix the hook arm 932 on the nail wire 91.

[0042] On the basis that the existing nail-making machine body 1 can produce the nail body 931, an inlet line for the hook line 92 can be further provided, and the hook line 92 is arranged directly above the nail line 91. Through the setting of the automatic feeder 2, it is convenient to intermittently convey the hook line 92, so as to form a double-line feeding with the nail line 91, so as to be respectively processed into the hook arm 932 and the nail body 931 on the hook nail 93 subsequently; through the setting of the punching mechanism 3, the connection hole is processed on the hook line 92 in advance, so that the end of the nail line 91 can pass through the connection hole and then the end of the nail line 91 is stamped and formed, so as to facilitate the more stable riveting and fixing of the hook arm 932 on the nail line 91; through the setting of the stamping die 4, the male die 41 is driven by the punch 161 to stamp towards the female die 42 side, and with the cooperation of the clamping die device 13, only through one stamping and forming, the hook line 92 can be cut off, the cut hook line 92 can be stamped into the hook arm 932, and the end of the nail line 91 can be stamped into the nail head 933 and the hook arm 932 is riveted and fixed on the nail line 91. Then, the nail line 91 is cut off by the cutting device 18 to form the nail body 931, so that finally a hook nail 93 including the hook arm 932 and the nail body 931 can be formed. The hook nail 93 can stably fix the hook arm 932 on the nail body 931 without welding as a whole. The hook nail 93 has good firmness after processing, and it is not easy for the hook arm 932 and the nail body 931 to crack and loosen, effectively ensuring the finished product quality of the hook nail, greatly simplifying the processing and manufacturing process of the hook nail, with simple processes. Compared with the existing production method of hook nails, it greatly improves the production efficiency of hook nails, reduces the number of hook nail production equipment used, thus greatly reducing the overall floor area of the production equipment, and at the same time can greatly reduce the equipment input cost, equipment energy consumption and labor cost, bringing better economic benefits to the enterprise. During the production process, the handling of materials can be greatly reduced, the whole production process is more relaxed and labor-saving, and at the same time the labor intensity of the operators is reduced.

[0043] Such as Figure 13 , Figure 14 , Figure 15 and Figure 16As shown, specifically, an arc-shaped protrusion 421 is provided on the mold clamping surface of the female mold 42, and an arc-shaped concave portion 411 is provided on the mold clamping surface of the male mold 41. When the male mold 41 and the female mold 42 are clamped, a first mold cavity 43 for forming the hook arm 932 is formed by surrounding between the arc-shaped protrusion 421 and the arc-shaped concave portion 411. When the male mold 41 presses towards the female mold 42, through the cooperation of the arc-shaped protrusion 421 and the arc-shaped concave portion 411, the cut hook wire 92 can be well pressed into the hook arm 932 with a bent structure. A second mold cavity 412 for pressing the end of the nail wire 91 is also provided on the mold clamping surface of the male mold 41. Through the arrangement of the second mold cavity 412, when the male mold 41 presses towards the female mold 42, the second mold cavity 412 of the male mold 41 can play a corresponding pressing role on the end of the nail wire 91. At the same time, with the cooperation of the clamping device 13 clamping the nail wire 91, a pressing portion 9331 and a limiting portion 9332 can be respectively formed on both sides of the end of the nail wire 91 with respect to the hook wire 92. The pressing portion 9331 and the limiting portion 9332 are combined to form the nail head 933 and the hook arm 932 is riveted and fixed to the nail wire 91. In addition, the second mold cavity 412 can also play a corresponding shaping role on the pressing portion 9331. A cutting head 413 for cutting the hook wire 92 is also fixedly provided at the upper side edge of the mold clamping surface of the male mold 41. Through the arrangement of the cutting head 413, when the male mold 41 presses towards the female mold 42, the cutting head 413 can quickly cut the hook wire 92, thus facilitating subsequent stamping and forming.

[0044] As Figure 7 and Figure 15 shown, a through hole 414 penetrating the male mold 41 is further provided on the bottom surface of the second mold cavity 412, and a punching rod 44 adapted to the through hole 414 is fixedly provided on the punch 161. One end of the punching rod 44 passes through the through hole 414 and extends into the second mold cavity 412. By adopting this structure, when pressing the end of the nail wire 91, direct wear on the male mold 41 can be avoided. When the punching rod 44 is worn after performing a punching action on the end of the nail wire 91 for a period of time, only the punching rod 44 needs to be replaced, and there is no need to replace the male mold 41. Thus, the service life of the male mold 41 can be extended, the subsequent use cost can be reduced, and at the same time, the punching effect of the punching rod 44 on the end of the nail wire 91 can be well ensured. In addition, two first positioning holes are provided on the male mold 41, and two second positioning holes corresponding to the first positioning holes are provided on the punch 161. A first positioning pin is inserted into the first positioning hole and the second positioning hole. Through the arrangement of the first positioning pin, a corresponding positioning role can be played on the installation of the male mold 41, facilitating the accurate installation of the male mold 41 on the punch 161.

[0045] As Figure 7 and Figure 10 shown, the punching mechanism 3 includes a punching rod 31 and a punching seat 32. The punching rod 31 is fixedly arranged on a fixing block 311, and the fixing block 311 is fixedly installed on the punch head 161. The punching seat 32 is fixedly installed on the clamping die seat 131. An inlet channel 321 that penetrates through the upper and lower ends and is adapted to the hook line 92 is provided in the punching seat 32. The hook line 92 is movably threaded through the inlet channel 321. A punching hole 322 that penetrates through the front and rear ends and corresponds to and is adapted to the punching rod 31 is further provided in the punching seat 32, that is, the central axis of the punching hole 322 coincides with the central axis of the punching rod 31. The punching hole 322 communicates with the inlet channel 321. Through the setting of the punching seat 32, when the hook line 92 is threaded through the inlet channel 321, the punching seat 32 can play a corresponding role in stably supporting and limiting the hook line 92, so that when the punching rod 31 is driven by the punch head 161 and smoothly inserted into the punching hole 322, a connection hole can be well punched on the hook line 92. In addition, a slag discharge hole 1311 that communicates with the punching hole 322 is provided on the clamping die seat 131, and a slag discharge groove 112 that communicates with the slag discharge hole 1311 is provided on the machine base 11. Through the settings of the slag discharge hole 1311 and the slag discharge groove 112, the waste slag generated by punching the hook line 92 at the punching hole 322 can be discharged in time. In addition, a slag discharge rod 1121 that is inclined downward is fixedly connected to the machine base 11 at the position of the slag discharge groove 112. A slag discharge cavity is provided in the slag discharge rod 1121. Through the setting of the slag discharge rod 1121, the discharged waste slag can be discharged and collected in time, avoiding accumulation on the nail making machine body 1.

[0046] As Figure 10As shown in the figure, specifically, the punching seat 32 includes a front punching block 323 and a rear punching block 324 that are fixedly connected to each other. At least one of the front punching block 323 and the rear punching block 324 is provided with an incoming wire groove. The front punching block 323 and the rear punching block 324 enclose the incoming wire groove to form the incoming wire channel 321. The front punching block 323 is provided with a front punching hole 322, and the rear punching block 324 is provided with a rear punching hole 322. The front punching hole 322 and the rear punching hole 322 are combined to form the punching hole 322. By adopting this structure, it is convenient to process and manufacture the punching seat 32. In addition, the front punching block 323 is provided with two third positioning holes, the rear punching block 324 is provided with two fourth positioning holes, and the clamping die seat 131 is provided with two fifth positioning holes. The central axes of the third positioning hole, the fourth positioning hole, and the fifth positioning hole coincide. A second positioning pin is inserted into the third positioning hole, the fourth positioning hole, and the fifth positioning hole. Through the setting of the second positioning pin, it can play a good positioning role in the installation of the punching seat 32, facilitating the accurate installation of the punching seat 32 on the clamping die seat 131.

[0047] As Figure 4 , Figure 6 and Figure 9 shown in the figure, the automatic feeder 2 includes a feeding box 21 and a feeding transmission component 22. One side of the machine base 11 is fixedly provided with a mounting seat 111. A rotatable feeding transmission shaft 23 is installed on the mounting seat 111. Specifically, the feeding transmission shaft 23 can be rotationally connected to the mounting seat 111 through a bearing. One end of the left transmission shaft 14 on the nail making machine body 1 extends outward to the mounting seat 111. One end of the feeding transmission shaft 23 is drivingly connected to one end of the left transmission shaft 14 through a bevel gear assembly 24. Specifically, the bevel gear assembly 24 includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly installed on the left transmission shaft 14, and the second bevel gear is fixedly installed on the feeding transmission shaft 23. The first bevel gear and the second bevel gear are meshed and driven. The other end of the feeding transmission shaft 23 is drivingly connected to the feeding box 21 through the feeding transmission component 22. The feeding box 21 is fixedly installed on the machine base 11 through a feeding support seat 25. The feeding box 21 is used for intermittently conveying the hook wire 92. Through the driving connection of the left transmission shaft 14, the driving device 15 on the nail making machine body 1 can be directly used to drive the automatic feeder 2 to work, further making the overall structure more compact and without additional energy consumption. The left transmission shaft 14 can drive the feeding transmission shaft 23 to rotate, thereby driving the action of the feeding box 21 through the feeding transmission component 22, so that the feeding box 21 can intermittently feed the hook wire 92 as the nail making machine body 1 works.

A plurality of rotatable straightening wheels 52 are spaced apart along the conveying direction of the hook wire 92 on both sides of the hook wire 92 on one side surface of the straightening seat 51. In addition, the straightening wheels 52 can be installed on the straightening seat 51 through bolt assemblies. Through the setting of the straightening mechanism 5, the hook wire 92 can be well straightened, facilitating subsequent processing and production of the hook wire 92. Preferably, 2-3 straightening wheels 52 are provided on both sides of the hook wire 92. In addition, a limiting plate 53 is provided on one side of one of the straightening wheels 52, which can play a certain role in limiting and preventing deviation of the transmission of the hook wire 92. The limiting plate 53 can be fixedly connected to the bolt assembly.

[0050] As Figure 1 and Figure 2As shown, a steering mechanism 6 is further provided on the nail-making machine body 1 above the straightening mechanism 5. Specifically, the steering mechanism 6 includes a steering rod 61. Both ends of the steering rod 61 are fixedly connected with support rods 62. The support rods 62 are fixedly installed on the machine base 11. A rotatable steering wheel 63 is installed on the steering rod 61. An annular limiting groove 631 adapted to the hook wire 92 is provided on the outer surface of the steering wheel 63. During the transmission of the hook wire 92, it can be clamped in the annular limiting groove 631 to play a corresponding limiting role on the hook wire 92, so as to better ensure the transmission of the hook wire 92. Through the setting of the steering mechanism 6, it can play a corresponding steering role in the transmission of the hook wire 92, so that the hook wire 92 can better transition from horizontal transmission to vertical transmission.

[0051] As Figure 6 and Figure 11 As shown, a guiding mechanism 7 is further provided on the nail-making machine body 1 between the punching mechanism 3 and the automatic feeder 2. Specifically, the guiding mechanism 7 includes a guiding seat 71. The guiding seat 71 is fixedly installed on a mounting plate 72. The mounting plate 72 is fixedly arranged on the clamping die seat 131. A guiding channel 711 penetrating through the upper and lower ends and adapted to the hook wire 92 is provided in the guiding seat 71. The hook wire 92 can movably pass through the guiding channel 711. Since there is still a small distance between the automatic feeder 2 and the punching mechanism 3, through the setting of the guiding mechanism 7, when the hook wire 92 passes through the guiding channel 711, it can play a corresponding guiding role in the transmission of the hook wire 92, so that the hook wire 92 can smoothly enter the incoming wire channel 321 of the punching seat 32, and it can well avoid the hook wire 92 from bending during the transmission between the automatic feeder 2 and the punching mechanism 3 and being unable to smoothly enter the punching mechanism 3, thereby further ensuring the smooth feeding of the hook wire 92.

[0052] As Figure 11 As shown, specifically, the guiding seat 71 includes a front guiding block 712 and a rear guiding block 713 which are fixedly connected to each other. At least one of the front guiding block 712 and the rear guiding block 713 is provided with a guiding groove. The front guiding block 712 and the rear guiding block 713 enclose each other and the guiding groove forms the guiding channel 711. By adopting this structural setting, it is convenient to process and manufacture the guiding seat 71.

[0053] As Figure 6 and Figure 12As shown in the figure, a material slapping mechanism 8 is further provided on the nail making machine body 1. The material slapping mechanism 8 includes a slapping plate 81 and a return spring 82. One end of the slapping plate 81 is fixedly installed at one end of a rotating shaft 83, and the other end of the slapping plate 81 extends between the male die 41 and the female die 42. The rotating shaft 83 is installed on two pedestal bearings 84, and the pedestal bearings 84 are fixedly installed on the machine base 11. The other end of the rotating shaft 83 is fixedly connected to one end of a swing rod 85. One end of the return spring 82 is fixedly connected to the other end of the swing rod 85, and the other end of the return spring 82 is fixedly connected to the machine base 11. The return spring 82 is used to apply an elastic force to the swing rod 85 to keep the slapping plate 81 away from the female die 42. Preferably, the return spring 82 can be a tension spring. When the male die 41 is driven by the punch 161 to press forward, it can push the slapping plate 81 to the side of the female die 42 and turn downward. By adopting this structure, when the punch 161 drives the male die 41 to press toward the female die 42, the male die 41 can first push the slapping plate 81 to the side of the female die 42 and turn downward, and quickly slap the hook nail 93 formed by the previous stamping downward, so that the hook nail 93 quickly falls and moves away from the female die 42, thereby ensuring the smooth stamping between the male die 41 and the female die 42 very well, effectively avoiding the interference of the hook nail 93 that has not fallen in time on the stamping between the male die 41 and the female die 42, and effectively ensuring the stamping quality of the hook nail. When the punch 161 drives the male die 41 away from the female die 42, at this time, under the elastic force of the return spring 82 on the swing rod 85, the swing rod 85 can swing, so that the rotating shaft 83 rotates, thereby making the slapping plate 81 away from the female die 42 and keeping it in contact with the male die 41 for the material slapping action before the next stamping.

[0054] The using method of the automatic hook nail stamping and forming equipment, adopting the automatic hook nail stamping and forming equipment described in any one of the above, includes the following steps:

[0055] Step 1: The nail wire 91 is horizontally fed laterally intermittently by the feeding device 12 of the nail making machine body 1, and the hook wire 92 enters between a plurality of straightening wheels 52 after being turned by the steering wheel 63 for straightening and is vertically fed downward intermittently by the automatic feeder 2;

[0056] Step 2: The hook wire 92 fed downward intermittently passes through the guiding channel 711 on the guiding seat 71 and enters the wire inlet channel 321 of the punching seat 32;

[0058] Step 4: The hook wire 92 with the connection hole punched continues to be intermittently conveyed downward. At the same time, one end of the nail wire 91 passes through the connection hole under the intermittent conveyance of the feeding device 12. At this time, the central axes of the nail wire 91, the connection hole and the punching rod 44 coincide;

[0059] Step 5: Driven by the punch 161, the male mold 41 moves towards the female mold 42. The cutting head 413 on the male mold 41 can cut off the hook wire 92, and the arc-shaped concave part 411 of the male mold 41 can punch the cut hook wire 92 into a bent hook arm 932 in cooperation with the arc-shaped convex part 421 of the female mold 42. At the same time, the punching rod 44 in the second mold cavity 412 on the male mold 41 can punch the end of the nail wire 91 into a nail head 933 under the cooperation of the clamping device 13 clamping the nail wire 91 and rivet the hook arm 932 to the nail wire 91;

[0060] Step 6: The nail wire 91 with the nail head 933 punched and the hook arm 932 riveted continues to be conveyed forward, and then the nail wire 91 is cut by the cutting device 18 on the nail making machine body 1 to form a nail body 931, and finally a hook nail 93 composed of the nail body 931 and the hook arm 932 is formed;

[0061] Step 7: The formed hook nail 93 quickly drops downward under the material-patting action of the clapper 81 and is collected. Steps 1 to 6 are repeated to realize the continuous automatic stamping and forming of the hook nail 93.
