Description

Technical Field

[0001] This utility model relates to the technical field of screw processing, specifically to a spiral road spike forming device. Background Technology

[0002] As a critical track fastener, spiral rail spikes, with their superior pull-out resistance, anti-loosening performance, and high fatigue resistance, significantly enhance the overall rigidity and stability of the track frame. They effectively prevent major safety accidents caused by fastener failure, such as track geometry deviations and even rail fractures, providing crucial technical support for the long-term safe operation of major infrastructure such as high-speed railways and heavy-haul railways. Market demand continues to grow. The forming process of the bolt consists of five steps: cold heading, bolt assembly, machining, thread rolling, and thread hobbing.

[0003] Chinese Patent Publication No. CN217912712U discloses a multi-station cold heading machine for screw production. Its key technical features include a worktable and a support plate mounted on top of the worktable. The support plate is equipped with a drive assembly, and the output end of the drive assembly has an upper pressure plate. The bottom surface of the upper pressure plate has multiple punching heads. A rotary motor is located at the bottom of the inner wall of the worktable, and the output end of the rotary motor has a turntable. The turntable has at least two sets of lower plates. Each set of lower plates has punching grooves corresponding to the multiple punching heads, and the bottom of each set of lower plates has an ejector assembly that ejects workpieces from the multiple punching grooves.

[0004] In the above scheme, the workpiece is stamped into shape by a stamping head, and then the formed workpiece is ejected from the stamping groove by an ejector rod. This has the following disadvantages: after the workpiece is ejected from the stamping groove, the debris in the stamping groove cannot be processed, which leads to the possibility of subsequent workpieces getting stuck when placed into the stamping groove, thus reducing the integrity and quality of the workpiece. Utility Model Content

[0005] The purpose of this invention is to provide a spiral road spike forming device to solve the problem that after the workpiece is ejected from the stamping groove, the debris in the stamping groove cannot be processed, which leads to the subsequent workpiece getting stuck when placed into the stamping groove, thus reducing the integrity and quality of the workpiece.

[0006] To achieve the aforementioned utility model objectives, the present utility model adopts the following technical solution: a spiral road spike forming device, comprising a connecting block rotatably disposed above a workbench, an air inlet groove formed on the top surface of the connecting block, through holes formed on all four sides of the outer wall of the connecting block, all of which communicate with the air inlet groove, an air pipe fixed to the top surface of the connecting block, connecting boxes fixed on all four sides of the outer wall of the connecting block, lower fitting plates fixed to the top surface of several connecting boxes, stamping grooves formed on the top surface of several lower fitting plates, and inner... Each of the bottom surfaces has an ejector hole. Several connecting boxes have movably mounted top plates inside. Each top plate is hollow. The inner wall of each connecting box has a connecting hole. A flexible hose is fixed between the connecting hole and the top plate. Each top plate has several vent holes on its top surface, all of which are connected to the interior of the top plate. A top rod is fixed to the top surface of the top plate and is slidably inserted into the ejector hole. Air vents are located on the front and rear sides of the outer wall of the top rod. A conveying hole is located at the bottom end of the top rod, and the conveying hole is connected to the air vent.

[0007] Preferably, a first cylinder is fixed to the inner bottom surface of each of the connecting boxes, and one end of the telescopic rod of each of the first cylinders is connected to the bottom surface of each of the top plates. A fixing groove is provided on the top surface of the workbench, and a motor is fixed inside the fixing groove. The output shaft of the motor is connected to the bottom surface of the connecting block. An L-shaped plate is fixed to the top surface of the workbench, and a second cylinder is fixed to the top surface of the L-shaped plate. One end of the telescopic rod of the second cylinder passes through the L-shaped plate and is fixed to an upper pressure plate. A plurality of punching heads are fixed to the bottom surface of the upper pressure plate.

[0008] Preferably, the connecting hole is funnel-shaped.

[0009] Preferably, the inner walls of the plurality of connecting boxes are provided with sliding grooves on both sides, and the outer walls of the plurality of top plates are fixed with sliders on both sides, and the two sliders are respectively slidably disposed in the two sliding grooves.

[0010] Preferably, the bottom surface of the upper pressure plate is fixed with two positioning shafts, and the top surface of each of the several lower plates is provided with two positioning grooves, with the two positioning grooves respectively positioning the two positioning shafts.

In use, through the coordinated action of the connecting block, worktable, air inlet slot, air pipe, connecting box, lower plate, stamping slot, top plate, connecting hole, hose, exhaust hole, ejector rod, air outlet and conveying hole, high-pressure airflow can be used to blow away debris after the workpiece is stamped and ejected, effectively avoiding the problem of debris jamming, ensuring the cleanliness of the stamping slot, thereby improving the integrity and quality of the workpiece, reducing the defect rate caused by debris, and reducing production costs; Second, during use, the flared design provides ample displacement space for the hose to move, effectively reducing friction between the hose and the connection hole when the hose moves with the top plate, thus extending the service life of the hose. When the top plate moves up and down via the first cylinder, the slider slides inside the groove, limiting the top plate and ensuring its stability during up and down movement. Thirdly, during use, when the upper pressure plate is pressed down, the positioning shaft first inserts into the positioning groove for auxiliary positioning, allowing the punching head to accurately enter the punching groove and precisely punch the workpiece, thus improving the accuracy of punching. The limiting post slides inside the limiting hole, which can limit the upper pressure plate and ensure that the upper pressure plate will not deviate or shake during the up and down movement, thus improving stability.

[0018] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1-4As shown, a spiral road spike forming device includes a connecting block 1, which is rotatably mounted above a workbench 2. An air inlet groove 3 is formed on the top surface of the connecting block 1. Through holes are formed on all four sides of the outer wall of the connecting block 1, all of which communicate with the air inlet groove 3. An air pipe 4 is fixed to the top surface of the connecting block 1. Connecting boxes 5 are fixed to all four sides of the outer wall of the connecting block 1. Lower fitting plates 6 are fixed to the top surfaces of several connecting boxes 5. Stamping grooves 7 are formed on the top surfaces of several lower fitting plates 6. Each of the internal bottom surfaces has an ejector hole. Several connecting boxes 5 have movable top plates 8 inside. The top plates 8 are hollow. Connecting holes 9 are formed on the inner side of the inner wall of each connecting box 5. Flexible hoses 10 are fixedly connected between the connecting holes 9 and the top plates 8. Several vent holes 11 are formed on the top surface of each top plate 8, and these vent holes 11 are all connected to the interior of the top plate 8. A top rod 12 is fixed to the top surface of the top plate 8 and is slidably inserted into the ejector hole. The front and rear sides of the outer wall of the top rod 12 are... An air outlet 13 is provided, and a conveying hole 14 is provided at the bottom end of the top rod 12. The conveying hole 14 is connected to the air outlet 13. A first cylinder 15 is fixed inside the bottom surface of several connecting boxes 5. One end of the telescopic rod of several first cylinders 15 is connected to the bottom surface of several top plates 8. A fixing groove 16 is provided on the top surface of the worktable 2. A motor 17 is fixed inside the fixing groove 16. The output shaft of the motor 17 is connected to the bottom surface of the connecting block 1. An L-shaped plate 1 is fixed on the top surface of the worktable 2. 8. A second cylinder 19 is fixed on the top surface of the L-shaped plate 18. One end of the telescopic rod of the second cylinder 19 passes through the L-shaped plate 18 and is fixed with an upper pressure plate 20. Several punch heads 21 are fixed on the bottom surface of the upper pressure plate 20. Both the first cylinder 15 and the second cylinder 19 are equipped with air compressors. The air compressors are connected to the air inlet ports of the first cylinder 15 and the second cylinder 19 respectively through two high-pressure sealed air pipes to provide synchronous air pressure power for the first cylinder 15 and the second cylinder 19 to drive the telescopic rod to extend and retract.

[0020] During use, the staff first securely connects the air pipe 4 to the high-pressure air source equipment to ensure unobstructed airflow. Then, they precisely align a set of lower plates 6 and upper pressure plates 20 on the workbench 2. At this time, multiple stamping heads 21 are directly aligned with multiple stamping slots 7, preparing for subsequent stamping operations.

[0021] Next, by controlling the air compressor, the second cylinder 19 is driven to work. At this time, the telescopic rod of the second cylinder 19 will extend and retract, driving the upper pressure plate 20 to press down smoothly. During the pressing process, the punch head 21 on the bottom surface of the upper pressure plate 20 punches and forms the workpiece placed in the punching groove 7, ensuring that the workpiece achieves the required shape and dimensional accuracy. After the pressing action is completed, the motor 17 is started. The output shaft of the motor 17 drives the connecting block 1 to rotate 90 degrees, accurately rotating the second set of lower plates 6 to the position aligned with the upper pressure plate 20.

[0022] At this time, the first cylinder 15 is activated, and its telescopic rod extends, driving the top plate 8 and the push rod 12 to move upward. The push rod 12 pushes the stamped workpiece out of the stamping groove 7 through the ejection hole, and the finished workpiece is taken away. At the same time, the high-pressure air source equipment delivers high-pressure air to the air pipe 4. After the high-pressure gas enters the air inlet groove 3, it enters the hose 10 through the connection hole 9, and then enters the interior of the top plate 8. Subsequently, it enters the conveying hole 14 through the exhaust hole 11, and finally sprays out from the air outlet 13. The strong airflow can completely blow out the residual debris in the stamping groove 7, effectively preventing the debris from getting stuck in the stamping groove 7, and ensuring the smooth progress of subsequent stamping operations.

[0023] During the pressing process of the first set of lower plates 6, the second set of lower plates 6 can be pre-installed with the workpiece to be processed, realizing the alternating preparation of the workpiece to be processed and the processed workpiece. After the first set of lower plates 6 is pressed, the connecting block 1 is rotated to make the second set of lower plates 6 in the pressing position. Then, the workpiece processed by the first set of lower plates 6 is ejected and the subsequent filling is carried out. This cycle of processing realizes the multi-station cycle processing mode of the device.

[0024] Through the coordinated action of connecting block 1, worktable 2, air inlet groove 3, air pipe 4, connecting box 5, lower plate 6, stamping groove 7, top plate 8, connecting hole 9, hose 10, exhaust hole 11, ejector rod 12, air outlet 13 and conveying hole 14, high-pressure airflow can be used to blow away debris after the workpiece is stamped and ejected, effectively avoiding the problem of debris jamming, ensuring the cleanliness of stamping groove 7, thereby improving the integrity and quality of the workpiece, reducing the defect rate caused by debris, and lowering production costs.

[0025] like Figures 2-4 As shown, the connecting hole 9 is shaped like a trumpet.

[0026] During use, the flared design provides ample displacement space for the hose 10 to move, effectively reducing friction between the hose 10 and the connection hole 9 when the hose 10 moves with the top plate 8, and extending the service life of the hose 10.

[0027] like Figures 1-4 As shown, the inner walls of several connecting boxes 5 are provided with sliding grooves 22 on both sides, and the outer walls of several top plates 8 are fixed with sliders 23 on both sides. The two sliders 23 are slidably arranged in the two sliding grooves 22 respectively.

[0028] In use, when the top plate 8 moves up and down via the first cylinder 15, the slider 23 slides inside the slide groove 22, which can limit the top plate 8 and ensure the stability of the top plate 8 during the up and down movement.

[0029] like Figures 1-4As shown, the bottom surface of the upper pressure plate 20 is fixed with two positioning shafts 24, and the top surface of several lower plates 6 is provided with two positioning grooves 25. The two positioning grooves 25 respectively position the two positioning shafts 24. The top surface of the L-shaped plate 18 is provided with two limiting holes 26, and the top surface of the upper pressure plate 20 is fixed with two limiting posts 27. The two limiting posts 27 are slidably inserted into the two limiting holes 26 respectively.

[0030] During use, when the upper pressure plate 20 is pressed down, the positioning shaft 24 first inserts into the positioning groove 25 for auxiliary positioning, allowing the punch head 21 to accurately enter the punching groove 7 and precisely punch the workpiece, thus improving the accuracy of the punching. When the upper pressure plate 20 moves up and down via the second cylinder 19, the limiting post 27 slides inside the limiting hole 26, limiting the upper pressure plate 20 and ensuring that it does not shift or shake during the up and down movement, thus improving stability.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
