Description

Technical Field

[0001] The invention relates to the technical field of cold heading, in particular to fastener multi-station synchronous forming cold heading equipment and a forming method. Background Art

[0002] Cold heading technology uses the principle of plastic deformation of metal materials at room temperature to apply external force and speed to metal wire through a die to force it to produce plastic flow, thereby extruding parts of the required shape and size. It is mainly operated by a cold heading machine and is mainly used to manufacture fasteners such as screws, nuts and steel nails.

[0003] In the production process of fasteners such as screws, metal wires or bars are first selected as raw materials, and then the raw materials are cut according to the length requirements of the screws. Then, one end of the cut raw materials is pressed into a predetermined shape by pressure to form the head of the screw. Finally, the metal material is gradually plastically deformed into a threaded shape through a mold of specified specifications by cold extrusion, thereby completing the production of the screws. With the development of society, the demand for fasteners is constantly increasing, so multi-station cold heading machines have also appeared. Through multi-station cold heading machines, multiple raw materials such as metal wires or bars can be processed at the same time, greatly improving the production efficiency of screws;

[0004] After the screws are produced by the cold heading equipment, most of the screws pass through the feeding port by free fall. In addition, since the multi-station cold heading equipment can process multiple screws at the same time, there are a large number of screws when the screws are fed, and multiple screws are easily piled up together, affecting the feeding efficiency of the screws. At the same time, when the screws enter the container, the placement of the screws becomes messy and disordered. Since the tip end of the screw usually has sharp corners, when the workers manually collect and check the screws, they are easily pierced by the disorderly placed screw tips. For this reason, we propose a multi-station synchronous forming cold heading equipment and forming method for fasteners. Summary of the invention

[0005] The object of the present invention is to provide a fastener multi-station synchronous forming cold heading equipment and forming method to solve the problems raised in the above background technology.

[0007] A rotating rod is rotatably connected to the top of the partition plate. The rotating rod is located on one side of the channel entrance between the two guide plates. A diversion pipe is fixedly connected to the bottom of the partition plate. The diversion pipe is located below the filter screen. The bottom end of the rotating rod penetrates through the partition plate and is fixedly connected with a shaft rod. A plurality of uniformly distributed transmission plates are fixedly connected to the shaft rod. A diversion plate A is fixedly connected to one inner wall of the diversion pipe.

[0008] Preferably, a plurality of mounting frames are slidably connected to the side of the fixing frame away from the machine body. A limiting port is provided on the mounting frame. Mounting ports are provided on both sides of the top of the mounting frame. Transmission rollers are rotatably connected to both ends of the mounting port. A conveyor belt is arranged between the transmission rollers. A transmission wheel A is rotatably connected to one side of the mounting frame. A fixed connection is provided between the transmission wheel A and the transmission roller on the same side.

[0009] Preferably, limiting frames are fixedly connected to both sides of the bottom of the mounting frame. A mounting rod is rotatably connected between the limiting frames. A plurality of uniformly distributed water storage boxes are fixedly connected to the mounting rod. A transmission wheel B is rotatably connected to the limiting frame on one side of the bottom of the mounting frame close to the transmission wheel A. A transmission belt is arranged between the transmission wheel B and the transmission wheel A.

[0010] Preferably, a diversion plate B is fixedly connected to one side of the limiting port close to the machine body. The diversion plate B is located above the mounting rod. A blocking rod is fixedly connected between the two sides of the top of the mounting frame through a frame body.

[0011] Preferably, a mounting plate is fixedly connected to the side of the top of the mounting frame away from the machine body. A rack is fixedly connected to the top of the mounting plate.

[0012] Preferably, a motor is fixedly connected to the side of the fixing frame away from the machine body through a bracket. The output end of the motor is fixedly connected with a gear. The gear meshes with the rack.

[0013] Preferably, inlets and outlets are respectively provided on both sides of the fixing frame. The motor is close to one of the inlets and outlets. The inlet and outlet on the side of the fixing frame close to the motor is the inlet. Communication ports communicating with the inlets and outlets on the same side are provided on both sides of the fixing frame.

[0014] Preferably, a micro water pump is fixedly connected between the fixing frame and the partition plate. Water pipes are fixedly connected to both ends of the micro water pump. The micro water pump is docked with a water tank and a spray head through the water pipes respectively.

[0015] Preferably, a sealing cover is rotatably connected to the top of the machine body. The sealing cover is located above the mold. A controller is fixedly connected to one side of the machine body.

[0016] The forming method of the fastener multi-station synchronous forming cold heading equipment specifically includes the following steps:

[0017] S1: First, open the sealing cover, then put the workpiece into the designated position, and then close the sealing cover. At this time, the controller controls the operation of the machine body, and then the mold can be used to cold-forge the workpiece to process the workpiece into a screw of a designated type;

[0018] S2: When the workpiece is processed, it will enter the discharge port. At this time, the workpiece falls on the partition between the fixed frames through the discharge port. At this time, the micro water pump is started to transport the water in the water tank to the nozzle through the water pipe, and then sprayed out through the nozzle. At this time, the water sprayed by the nozzle will slide down along the partition. In this process, the screws on the partition can be cooled down and a driving force can be provided to the screws, so that the screws can slide down along the partition faster.

[0019] S3: When the water slides down the partition, it will pass through the filter. At this time, part of the water will enter the guide pipe through the filter and flow along the guide pipe. At this time, the water in the guide pipe will be concentrated on the transmission plate on one side of the shaft through the guiding function of the guide plate A, and thereby drive the shaft and the rotating rod to rotate counterclockwise. When the screw slides down the partition in a horizontal state to the entrance of the channel between the two guide plates, the screw in a horizontal state will be stuck at the entrance of the channel between the two guide plates. At this time, the rotating rod rotating counterclockwise will move one end of the screw, so that the screw enters the channels of the two guide plates vertically. At this time, the two guide plates cooperate to keep the screw in this state for material unloading;

[0020] S4: After the screw passes through the channel between the two guide plates, it will fall on the mounting frame. At this time, the head of the screw can be limited by the two sides of the mounting frame, and the tip of the screw is placed in the limit port by the gravity of the screw. After the water flowing along the screw passes through the channel between the two guide plates, it will flow along the guide plate B to the water storage box away from the machine body. At this time, the water storage box becomes heavy because it is filled with water, and starts to drive the mounting rod to rotate, and drives the transmission wheel B to rotate through the mounting rod. At this time, the transmission wheel B drives the transmission wheel A to rotate through the transmission belt. During the rotation of the transmission wheel A, it can drive the transmission roller connected to it to rotate, and drive the conveyor belt to move through the transmission roller. At this time, the screws on the mounting frame can be moved in the direction away from the machine body through the conveyor belt to provide a position for subsequent screws. During the movement of the screw, if a screw is stuck, causing its tip to face upward, during the movement of the screw, its tip will contact the stopper, and the fixed stopper cooperates with the moving screw to make the screw rotate, ensuring that the tip of the screw faces downward, so that the screws on the entire mounting frame are arranged more neatly.

[0021] S5: When one of the mounting racks is full of screws, the motor is started to drive the gear to rotate. During the rotation of the gear, it can cooperate with the meshing rack to drive the mounting rack connected to it to move through the mounting plate. At this time, during the movement of the mounting rack, the mounting rack located at the exit of the two guide plate channels can be moved toward the exit direction of the inlet and outlet, and the new mounting rack can be pushed to the exit of the channels of the two guide plates to collect the subsequent screws, and then a new mounting rack is placed at the entrance of the inlet and outlet. When the mounting rack full of screws moves to the exit of the inlet and outlet, the screws connecting the mounting rack are taken out together, and the screws on the mounting rack are placed in the designated centralized storage point, and then the mounting rack is put back into the fixed rack through the entrance of the inlet and outlet.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, when the screws are produced and unloaded, the screws will enter the partition and slide down along the partition, and cold water will be sprayed out through the nozzle. The screws will be cooled by the cold water while providing thrust to the screws, so that the speed of screw unloading will be increased. When the water sprayed out by the nozzle passes through the filter screen, part of the water will enter the guide tube and flow along the guide tube, and impact the transmission plate on one side of the shaft through the guiding function of the guide plate A, so that the rotating rod will rotate. At this time, the two guide plates can cooperate to guide the screws, so that the screws can be unloaded through the channel between the two guide plates, so that the unloading of the screws is more orderly. When the screws are stuck at the channel entrance of the two guide plates in a horizontal state, one end of the screw can be moved by the rotating rotating rod, so that the screws are in a relatively vertical state, ensuring that the screws can smoothly enter the channel between the two guide plates, avoiding the problem that the screws are unloaded in a disorderly manner, resulting in a more disorderly fall in the container for storing screws, and effectively ensuring that the screws are unloaded in sequence while improving the efficiency of screw unloading;

[0024] 2. After the screw passes through the channel between the two guide plates, it will fall on the mounting rack. At this time, the head end of the screw is limited by both sides of the mounting rack, and the weight of the screw itself is utilized to make the tip of the screw located within the limiting opening. Since the water on the partition plate will also flow along with the screw, after passing through the channel between the two guide plates, the water will fall on the diversion plate B and flow into the water storage box on one side of the mounting rod. At this time, the water storage box becomes heavier and starts to drive the mounting rod to rotate. Thus, through the cooperation of the drive wheel B, the drive belt, and the drive wheel A, the drive roller is driven to rotate. During the rotation of the drive roller, the conveyor belt can be driven to move. At this time, the screw on the mounting rack is transported towards the end far away from the machine body through the conveyor belt, enabling the subsequent screws to smoothly fall on the mounting rack. The mounting rack arranges the screws in an orderly manner and makes the tip of the screw located within the limiting opening. When the staff collects and inspects the screws, they can directly hold the mounting rack to collect and inspect the screws, avoiding the problem that the traditional device is prone to injure the staff with the tip of the screw due to the disorderly arrangement of the screws;

[0025] 3. During the process of the screw being transported by the conveyor belt, if a screw is accidentally stuck and its tip faces upwards, at this time, the tip of the screw will contact the stop rod. At this time, through the cooperation of the fixed stop rod and the moving screw, a squeezing force is generated on the screw to make the screw rotate, ensuring that the tip of the screw is within the limiting opening, further improving the protection of the device for the staff.

Specific embodiments

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-9 , the present invention provides a technical solution: a multi-station synchronous forming cold heading device for fasteners, including a body 1, a mold 11 is fixedly connected inside the body 1, the mold 11 has a plurality of processing channels, and can simultaneously process a plurality of metal raw materials. A blanking port 12 is opened inside the body 1, the blanking port 12 is located below the mold 11, a sealing cover 13 is rotatably connected to the top of the body 1, the sealing cover 13 is located above the mold 11, and a controller 14 is fixedly connected to one side of the body 1.

[0038] Further, the body 1 is the main structure of a multi-station cold heading machine. A plurality of molds 11 are arranged inside the body 1, and each mold 11 can independently perform cold heading processing on metal wire or metal rod raw materials. When performing cold heading processing of fasteners, the sealing cover 13 is opened, and then raw materials such as metal wire or metal rod are placed at the specified position, and then the sealing cover 13 is closed, and the body 1 is started through the controller 14. At this time, the raw materials such as metal wire or metal rod can be cold headed by the mold 11 to make screws of specified specifications.

[0039] Combined with the attached Figure 3 , Figure 4 , Figure 5 and Figure 9As shown in the figure, a fixing frame 2 connected to the blanking port 12 is fixedly connected to one side of the machine body 1. A partition plate 21 is fixedly connected inside the fixing frame 2. Two guiding plates 3 are fixedly connected to the top of the partition plate 21. The space between the two guiding plates 3 is in a "Y" shape. A channel is formed between the two guiding plates 3. The channel is relatively narrow, enabling the screws to be fed vertically. A spray head 31 is fixedly connected to one side of the top of the partition plate 21 close to the machine body 1. A filter screen 32 is fixedly connected to the partition plate 21. The filter screen 32 can block the screws to prevent them from entering the diversion pipe 41. Moreover, the filter screen 32 can also block the metal particles washed off the screws by water, avoiding the problem of jamming of the transmission plate 43 caused by the metal particles entering the diversion pipe 41. A rotating rod 4 is rotatably connected to the top of the partition plate 21. The rotating rod 4 is located on one side of the entrance of the channel between the two guiding plates 3. A diversion pipe 41 is fixedly connected to the bottom of the partition plate 21. The diversion pipe 41 is located below the filter screen 32. The bottom end of the rotating rod 4 penetrates through the partition plate 21 and is fixedly connected to a shaft rod 42. A number of uniformly distributed transmission plates 43 are fixedly connected to the shaft rod 42. A diversion plate A44 is fixedly connected to one inner wall of the diversion pipe 41. A micro water pump 51 is fixedly connected between the fixing frame 2 and the partition plate 21. Both ends of the micro water pump 51 are fixedly connected to water pipes 5. The micro water pump 51 is connected to the water tank 22 and the spray head 31 respectively through the water pipes 5.

[0040] Furthermore, an appropriate amount of water is filled in the water tank 22. During the process of screw blanking, the micro water pump 51 is started. By the cooperation of the micro water pump 51 and the water pipes 5, the water in the water tank 22 is pumped into the spray head 31. At this time, the spray head 31 can spray the water onto the partition plate 21. When the screws fall onto the partition plate 21, the water sprayed by the spray head 31 can cool the screws. At the same time, using the force generated by the flowing water, the screws are washed. This can not only wash some metal particles on the surface of the screws, but also accelerate the blanking speed of the screws, improving the blanking efficiency of the screws. When the water slides down along the partition plate 21, it will pass through the filter screen 32. At this time, part of the water will enter the diversion pipe 41 through the filter screen 32 and flow along the diversion pipe 41. At this time, through the guiding function of the diversion plate A44, the water in the diversion pipe 41 will concentrate on impacting the transmission plate 43 on one side of the shaft rod 42, and drive the shaft rod 42 and the rotating rod 4 to rotate counterclockwise. During the process of screw blanking, through the cooperation of the two guiding plates 3, the blanking path of the screws can be restricted, enabling the screws to pass through the channel between the two guiding plates 3 in sequence. If there are screws in the horizontal state stuck at the entrance of the channel between the two guiding plates 3, at this time, the rotating rod 4 rotating counterclockwise will push one end of the screw and straighten the screw, enabling it to smoothly enter the channel of the two guiding plates 3 and successfully complete the blanking work.

[0041] Combined with the attached Figure 3 、 Figure 6 、 Figure 7 andFigure 8 As shown, on the inner side of one side of the fixing frame 2 away from the body 1, a number of mounting frames 6 are slidably connected. A limiting opening 61 is formed on the mounting frame 6. On both sides of the top of the mounting frame 6, mounting openings 62 are formed. At both ends of the mounting opening 62, a driving roller 63 is rotatably connected. Between the driving rollers 63, a conveyor belt 64 is arranged. On one side of the mounting frame 6, a driving wheel A65 is rotatably connected. A fixed connection is provided between the driving wheel A65 and the driving roller 63 on the same side of it. On both sides of the bottom of the mounting frame 6, limiting frames 7 are fixedly connected. Between the limiting frames 7, a mounting rod 71 is rotatably connected. A number of evenly distributed water storage boxes 72 are fixedly connected to the mounting rod 71. On the limiting frame 7 on one side of the bottom of the mounting frame 6 close to the driving wheel A65, a driving wheel B73 is rotatably connected. A transmission belt 74 is arranged between the driving wheel B73 and the driving wheel A65. On the side of the limiting opening 61 close to the body 1, a diversion plate B66 is fixedly connected. The diversion plate B66 is located above the mounting rod 71. Between the two sides of the top of the mounting frame 6, a blocking rod 67 is fixedly connected through a frame body.

[0042] Further, when the screw passes through the channel between the two guiding plates 3, it will fall on the mounting frame 6. At this time, the two sides of the mounting frame 6 can limit the head of the screw, and due to the gravity of the screw, the tip of the screw is located in the limiting opening 61. The water flowing along with the screw will flow along the diversion plate B66 into the water storage box 72 on the side away from the body 1 after passing through the channel between the two guiding plates 3. At this time, after the water storage box 72 is filled with water, its weight increases, and it starts to drive the mounting rod 71 to rotate, and drives the driving wheel B73 to rotate through the mounting rod 71. At this time, the driving wheel B73 drives the driving wheel A65 to rotate through the transmission belt 74. During the rotation of the driving wheel A65, it can drive the driving roller 63 connected to it to rotate, and drive the conveyor belt 64 to move through the driving roller 63. At this time, the screw located on the mounting frame 6 can be moved in the direction away from the body 1 through the conveyor belt 64, providing a position for the subsequent screws. During the rotation of the mounting rod 71, the water storage box 72 filled with water will tilt, pour out the water inside it, and make the empty water storage box 72 rotate to the lower side of the diversion plate B66 and continue to collect water, thus completing the continuous rotation of the mounting rod 71. After the water flows out of the water storage box 72 and the diversion pipe 41, it will fall back into the water tank 22 again, and through the pumping function of the micro water pump 51, the water in the water tank 22 forms a cycle. When the water flows, it will cool itself, and through the recycling of the water in the water tank 22, the environmental protection of the device can be further improved. During the movement of the screw, if a screw gets stuck and its tip faces upward, during the movement of this screw, its tip will contact the blocking rod 67. Through the cooperation of the fixed blocking rod 67 and the moving screw, the screw rotates to ensure that the tip of the screw faces downward, making the arrangement of the screws on the entire mounting frame 6 more orderly.

[0043] Combined with the attachedFigure 3 and Figure 6 As shown in Figure 6 , on one side of the top of the mounting frame 6 away from the machine body 1, there is a fixedly connected mounting plate 8. On the top of the mounting plate 8, there is a fixedly connected rack 81. On one side of the fixing frame 2 away from the machine body 1, there is a fixedly connected motor 9 through a bracket. On the output end of the motor 9, there is a fixedly connected gear 91. The length of a single rack 81 is the same as the width of a single mounting frame 6. The gear 91 meshes with the rack 81. On both sides of the fixing frame 2, there are respectively provided inlet and outlet openings 23. The motor 9 is close to one of the inlet and outlet openings 23. The inlet and outlet opening 23 on the side of the fixing frame 2 close to the motor 9 is the inlet. On both sides of the fixing frame 2, there are provided communication openings 24 communicating with the inlet and outlet openings 23 on the same side thereof.

[0044] Furthermore, when the screws on one of the mounting frames 6 are filled up, at this time, start the motor 9 to drive the gear 91 to rotate. During the rotation of the gear 91, it can cooperate with the engaged rack 81, drive the connected mounting frame 6 through the mounting plate 8 to move. At this time, during the movement of this mounting frame 6, it can move the mounting frame 6 located at the channel outlet of the two guide plates 3 towards the outlet direction of the inlet and outlet opening 23, and push a new mounting frame 6 to the channel outlet of the two guide plates 3 to collect the subsequent screws. Then, place a new mounting frame 6 at the inlet of the inlet and outlet opening 23. When the mounting frame 6 filled with screws moves to the outlet of the inlet and outlet opening 23, take out the mounting frame 6 together with the screws, load the screws on the mounting frame 6 into the designated centralized storage point, and then put the mounting frame 6 back into the fixing frame 2 through the inlet of the inlet and outlet opening 23.

[0045] The forming method of the multi-station synchronous forming cold heading equipment for fasteners specifically includes the following steps:

[0046] S1: First, open the sealing cover 13, then place the workpiece at the designated position, and then close the sealing cover 13. At this time, control the operation of the machine body 1 through the controller 14, and then cold heading process the workpiece through the die 11 to process the workpiece into screws of the designated model;

[0047] S2: When the workpiece processing is completed, it will enter the blanking port 12. At this time, the workpiece falls on the partition 21 between the fixing frames 2 through the blanking port 12. At this time, start the micro water pump 51 to transport the water in the water tank 22 to the nozzle 31 through the water pipe 5, and then spray it out through the nozzle 31. At this time, the water sprayed out by the nozzle 31 will slide down along the partition 21. During this process, it can cool down the screws located on the partition 21 and provide a driving force for the screws to make the screws slide down along the partition 21 faster;

[0048] S3: When the water slides down the partition 21, it will pass through the filter screen 32. At this time, part of the water will enter the guide tube 41 through the filter screen 32 and flow along the guide tube 41. At this time, through the guiding function of the guide plate A44, the water in the guide tube 41 will be concentrated on the transmission plate 43 on one side of the shaft 42 to impact, and thereby drive the shaft 42 and the rotating rod 4 to rotate counterclockwise. When the screw slides down the partition 21 in a horizontal state to the entrance of the channel between the two guide plates 3, the screw in a horizontal state will be stuck at the entrance of the channel between the two guide plates 3, and the rotating rod 4 rotating counterclockwise will move one end of the screw, so that the screw enters the channels of the two guide plates 3 vertically. At this time, through the cooperation of the two guide plates 3, the screw is always in this state for unloading work;

[0049] S4: After the screw passes through the channel between the two guide plates 3, it will fall on the mounting frame 6. At this time, the head of the screw can be limited by the two sides of the mounting frame 6, and the tip of the screw is placed in the limiting opening 61 by the gravity of the screw. After the water flowing along the screw passes through the channel between the two guide plates 3, it will flow along the guide plate B66 to the water storage box 72 away from the side of the body 1. At this time, the water storage box 72 is filled with water, and its weight becomes, which starts to drive the mounting rod 71 to rotate, and drives the transmission wheel B73 to rotate through the mounting rod 71. At this time, the transmission wheel B73 drives the transmission wheel A6 through the transmission belt 74. 5 rotates, and the transmission wheel A65 can drive the transmission roller 63 connected thereto to rotate during the rotation process, and drive the conveyor belt 64 to move through the transmission roller 63. At this time, the screws on the mounting frame 6 can be moved in the direction away from the side of the machine body 1 through the conveyor belt 64 to provide positions for subsequent screws. In the process of screw movement, if a screw is stuck and its tip is facing upward, its tip will contact the stopper 67 during the movement of the screw. The fixed stopper 67 cooperates with the moving screw to rotate the screw, ensuring that the tip of the screw is facing downward, so that the screws on the entire mounting frame 6 are arranged more neatly.

[0050] S5: When one of the mounting frames 6 is full of screws, the motor 9 is started to drive the gear 91 to rotate. During the rotation of the gear 91, it can cooperate with the meshing rack 81 to drive the mounting frame 6 connected to it to move through the mounting plate 8. At this time, during the movement of the mounting frame 6, the mounting frame 6 located at the channel outlet of the two guide plates 3 can be moved toward the outlet direction of the inlet and outlet 23, and the new mounting frame 6 can be pushed to the channel outlet of the two guide plates 3 to collect the subsequent screws, and then a new mounting frame 6 is placed at the entrance of the inlet and outlet 23. When the mounting frame 6 full of screws moves to the exit of the inlet and outlet 23, the screws connected to the mounting frame 6 are taken out together, and the screws on the mounting frame 6 are placed in the designated centralized storage point, and then the mounting frame 6 is put back into the fixing frame 2 through the entrance of the inlet and outlet 23.

[0051] Working principle: install the machine body 1 at the designated position and power it on, and fill a proper amount of water into the water tank 22, then you can prepare for the production and processing of fastener screws. First, open the sealing cover 13, then put the raw materials such as metal wires or metal bars into the designated position, then close the sealing cover 13, and start the machine body 1 through the controller 14. At this time, the raw materials such as metal wires or metal bars can be cold-forged through the mold 11 to make them into screws of designated specifications. When the screws are processed, they will fall into the discharge port 12, and drop through the discharge port 12, and enter the partition 21 in the fixed frame 2;

[0052] When the screws are being cut, the micro water pump 51 is started, and the water in the water tank 22 is pumped into the nozzle 31 by the cooperation of the micro water pump 51 and the water pipe 5. At this time, the nozzle 31 can spray water onto the partition 21. When the screws are cut onto the partition 21, the water sprayed by the nozzle 31 can cool the screws. At the same time, the force generated by the water flow is used to flush the screws, which can not only wash away some metal particles on the surface of the screws, but also speed up the cutting of the screws. When the water slides down the partition 21, it will pass through the filter screen 32. At this time, part of the water will pass through the filter screen 32 into the guide tube 41 and flow along the guide tube 41. At this time, through the guiding function of the guide plate A44, the water in the guide tube 41 will be concentrated to impact the transmission plate 43 on one side of the shaft 42, and thereby drive the shaft 42 and the rotating rod 4 to rotate counterclockwise. In the process of screw feeding, the two guide plates 3 cooperate to limit the feeding path of the screw, so that the screw can be fed through the channel between the two guide plates 3 in sequence. If a screw in a horizontal state is stuck at the entrance of the channel between the two guide plates 3, the rotating rod 4 rotating counterclockwise will move one end of the screw to align the screw, so that it can smoothly enter the channels of the two guide plates 3 and successfully complete the feeding work.

[0053] After the screw passes through the channel between the two guide plates 3, it will fall on the mounting bracket 6. At this time, the two sides of the mounting bracket 6 can limit the head of the screw, and due to the gravity of the screw, the tip of the screw is positioned within the limiting opening 61. The water flowing along with the screw, after passing through the channel between the two guide plates 3, will flow along the guide plate B66 into the water storage box 72 on the side away from the machine body 1. At this time, after the water storage box 72 is filled with water, its weight increases, causing it to start driving the mounting rod 71 to rotate, and through the mounting rod 71, driving the driving wheel B73 to rotate. At this time, the driving wheel B73 drives the driving wheel A65 to rotate through the driving belt 74. During the rotation of the driving wheel A65, it can drive the driving roller 63 connected to it to rotate, and through the driving roller 63, drive the conveyor belt 64 to move. At this time, the screw located on the mounting bracket 6 can be moved in the direction away from the machine body 1 through the conveyor belt 64, providing a position for the subsequent screws. During the rotation of the mounting rod 71, the water storage box 72 filled with water will tilt, causing the water inside to pour out, and the empty water storage box 72 will rotate to the lower side of the guide plate B66 and continue to collect water, thus completing the continuous rotation of the mounting rod 71. During the movement of the screw, if a screw gets stuck and its tip faces upward, during the movement of this screw, its tip will contact the stop rod 67. Through the cooperation of the fixed stop rod 67 and the moving screw, the screw rotates to ensure that the tip of the screw faces downward;

[0054] When one of the mounting brackets 6 is filled with screws, the motor 9 is started at this time, causing it to drive the gear 91 to rotate. During the rotation of the gear 91, it can cooperate with the rack 81 meshed with it, and through the mounting plate 8, drive the connected mounting bracket 6 to move. At this time, during the movement of this mounting bracket 6, the mounting bracket 6 located at the outlet of the channel between the two guide plates 3 can be moved in the direction of the outlet of the inlet and outlet 23, and a new mounting bracket 6 can be pushed to the outlet of the channel between the two guide plates 3 to collect the subsequent screws. Then, a new mounting bracket 6 is placed at the inlet of the inlet and outlet 23. When the mounting bracket 6 filled with screws moves to the outlet of the inlet and outlet 23, the mounting bracket 6 together with the screws is taken out, and the screws on the mounting bracket 6 are loaded into the designated centralized storage point. Then, the mounting bracket 6 can be reinserted into the fixing frame 2 through the inlet of the inlet and outlet 23.

10. The forming method of the fastener multi-station synchronous forming cold heading equipment is characterized by: The forming method of the fastener multi-station synchronous forming cold heading equipment according to claim 9 specifically comprises the following steps: S1: First, the sealing cover (13) is opened, and then the workpiece is placed in a designated position, and then the sealing cover (13) is closed. At this time, the machine body (1) is controlled to operate by the controller (14), and then the workpiece is cold-forged by the mold (11) to be processed into a screw of a designated type; S2: When the workpiece is processed, it will enter the discharge port (12). At this time, the workpiece falls on the partition (21) between the fixed frame (2) through the discharge port (12). At this time, the micro water pump (51) is started to transport the water in the water tank (22) to the nozzle (31) through the water pipe (5), and then sprayed out through the nozzle (31). At this time, the water sprayed by the nozzle (31) will slide down along the partition (21). In this process, the screws on the partition (21) can be cooled and a driving force can be provided to the screws, so that the screws can slide down along the partition (21) faster. S3: When the water slides down the partition (21), it will pass through the filter (32). At this time, part of the water will enter the guide tube (41) through the filter (32) and flow along the guide tube (41). At this time, through the guiding function of the guide plate A (44), the water in the guide tube (41) will be concentrated to impact the transmission plate (43) on one side of the shaft (42), thereby driving the shaft (42) and the rotating rod (4) to rotate counterclockwise. When the screw slides down along the partition (21) in a horizontal state to the entrance of the channel between the two guide plates (3), the screw in a horizontal state will be stuck at the entrance of the channel between the two guide plates (3). At this time, the rotating rod (4) rotating counterclockwise will move one end of the screw, so that the screw enters the channel of the two guide plates (3) vertically. At this time, through the cooperation of the two guide plates (3), the screw is always in this state for material feeding; S4: After the screw passes through the channel between the two guide plates (3), it will fall on the mounting frame (6). At this time, the head of the screw can be limited by the two sides of the mounting frame (6), and the tip of the screw is placed in the limiting opening (61) by the gravity of the screw. After the water flowing along the screw passes through the channel between the two guide plates (3), it will flow along the guide plate B (66) to the water storage box (72) on the side away from the body (1). At this time, the water storage box (72) is filled with water, and its weight becomes, which starts to drive the mounting rod (71) to rotate, and drives the transmission wheel B (73) to rotate through the mounting rod (71). At this time, the transmission wheel B (73) drives the transmission belt (74) to drive the transmission wheel (73). The wheel A (65) rotates, and during the rotation process, the transmission wheel A (65) can drive the transmission roller (63) connected thereto to rotate, and drive the conveyor belt (64) to move through the transmission roller (63). At this time, the screws on the mounting frame (6) can be moved in a direction away from the side of the machine body (1) through the conveyor belt (64), so as to provide a position for subsequent screws. During the movement of the screws, if a screw is stuck, causing its tip to face upward, during the movement of the screw, its tip will contact the stopper (67), and the fixed stopper (67) cooperates with the moving screw to rotate the screw, ensuring that the tip of the screw faces downward, so that the screws on the entire mounting frame (6) are arranged more neatly; S5: When the screws on one of the mounting racks (6) are full, the motor (9) is started to drive the gear (91) to rotate. During the rotation of the gear (91), it can cooperate with the meshing rack (81) to drive the mounting rack (6) connected thereto to move through the mounting plate (8). During the movement of the mounting rack (6), the mounting rack (6) located at the channel exit of the two guide plates (3) can be moved toward the exit direction of the inlet and outlet (23), and a new mounting rack (6) is pushed to the channel exit of the two guide plates (3) to collect the subsequent screws, and then a new mounting rack (6) is placed at the entrance of the inlet and outlet (23). When the mounting rack (6) full of screws moves to the exit of the inlet and outlet (23), the mounting rack (6) and the screws connected thereto are taken out together, and the screws on the mounting rack (6) are placed in a designated centralized storage point, and then the mounting rack (6) is put back into the fixing rack (2) through the entrance of the inlet and outlet (23).
