Description

Technical Field

[0001] This utility model relates to the field of flange bolt thread rolling technology, and in particular to a flange bolt forming thread rolling machine. Background Technology

[0002] A flange bolt consists of two parts: a hexagonal head and a flange (with a gasket and hexagonal fixing piece underneath) and a threaded rod (a cylinder with external threads). It needs to be used with a nut to fasten two parts with through holes. The thread of the bolt is achieved by a thread rolling machine. However, in actual thread rolling operations, we have found that common thread rolling machines often use manual feeding to place the bolt blanks into the machine. That is, the bolt blanks are manually positioned on the machine one by one before thread rolling. However, this feeding method is slow and inefficient. Furthermore, during operation, the parts on the machine are in motion, and the user's hands frequently enter and exit the machine, which can easily lead to injury from the moving parts, posing a certain safety hazard.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0004] This utility model proposes a flange bolt forming thread rolling machine, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: A flange bolt forming thread rolling machine includes a worktable, a mounting frame fixedly installed on one side of the top of the worktable, a base fixedly installed on one side of the top of the worktable, a cam penetrating through the top of one side of the base, a fixed frame fixedly connected to one side of the base, a push arm adapted to the cam rotatably installed on the top of the fixed frame, a push rod movably installed at one end of the push arm, the push rod slidably installed on the mounting frame, a return spring sleeved on the surface of the push rod, the two ends of the return spring being fixedly connected to the push rod and the mounting frame respectively, a connecting block located outside the mounting frame being fixedly connected to one end of the push rod, and a push block slidably installed on the mounting frame being fixedly installed on one side of the connecting block.

[0006] The present invention, as described above, is used for flange bolt forming thread rolling machine. Further, a stepper motor is fixedly installed on one side of the worktable, and a second synchronous pulley is fixedly installed on the output shaft of the stepper motor. A first synchronous pulley is rotatably installed on one side of the base, and the first synchronous pulley and the second synchronous pulley are connected by a synchronous belt drive.

[0007] The present invention, as described above, is used for a flange bolt forming thread rolling machine. Further, a gear two located inside the base is rotatably mounted on one end of the synchronous wheel one, a gear one meshing with gear two is fixedly mounted on one end of the cam, a connecting arm is movably mounted on one side of gear one, and a sliding block is movably mounted on the end of the connecting arm away from gear one.

[0008] The present invention, as described above, is a thread rolling machine for forming flange bolts. Further, a guide rail is fixedly installed on one side of the top of the mounting frame, a sliding block is slidably installed inside the guide rail, and a thread rolling plate is detachably installed on one side of the sliding block.

[0009] The present invention, as described above, is used for a flange bolt forming thread rolling machine. Further, a stop block located on one side of the push block is slidably installed on one side of the top of the mounting frame, an adjusting screw is rotatably installed on one side of the stop block, a protective shell is fixedly installed on one side of the top of the worktable, and the adjusting screw is threadedly installed on the protective shell.

[0010] The present invention, as described above, is used for a flange bolt forming thread rolling machine. Further, a discharge hopper is fixedly installed on one side of the protective shell, and a feeding channel is fixedly installed on one side of the top of the mounting frame.

[0011] The present invention, as described above, is used for a flange bolt forming thread rolling machine. Further, a limiting slide rod is provided through one side of the mounting frame, and one end of the limiting slide rod is fixedly mounted on the connecting block.

[0012] In summary, the beneficial effects of this utility model are as follows: 1. This utility model adopts a structural design that can automatically push the bolt blank into the machine. The blank can be delivered outside the machine, and then the bolt blank is automatically pushed to the thread rolling station through the mechanical structure. This avoids injury to the fingers from contact with moving parts, improves the speed of bolt blank delivery, improves the efficiency of flange bolt thread rolling, improves the safety of the user's work, and provides convenience for the user's work.

[0013] 2. This utility model, through the arrangement of a guide rail, a sliding block, a thread rolling plate, a connecting arm, a first gear, a first synchronous pulley, a second gear, and a stepper motor, operates as follows: During operation, the stepper motor starts, driving the first synchronous pulley to rotate via a synchronous belt and synchronous pulley. The first synchronous pulley drives the second gear, which in turn drives the first gear. The first gear, through the connecting arm, pushes the sliding block to slide within the guide rail. The thread rolling plate mounted on the sliding block also moves along with it. Then, with the cooperation of a push block and a stop block, the thread rolling plate rolls threads onto the surface of the workpiece. It should be noted that a channel is formed between the thread rolling plate and the push block for the workpiece to pass through, and a channel is formed between the stop block and the thread rolling plate for the workpiece to move adaptively. Thus, with the cooperation of the thread rolling plate, the push block, and the stop block, the thread rolling plate rolls threads onto the workpiece. While the thread rolling process is underway, the workpiece is also being moved towards the discharge hopper until it leaves the thread rolling plate, push block, and stop block. The workpiece then falls into the discharge hopper, completing the discharge process. The guide rail limits the movement of the sliding block and the thread rolling plate. After this operation, the connecting arm, driven by the gear, pulls the sliding block back, and the thread rolling plate returns to its original position. The push block then moves outward to make room for the next workpiece. The push block then sends the workpiece back to the thread rolling plate, which moves again to perform the thread rolling process. This cycle repeats, achieving a fast and continuous working mode, increasing the speed and efficiency of flange bolt thread rolling, and providing convenience for users.

[0014] 3. This utility model, through the setting of a stop block, an adjusting screw, and a protective shell, allows the position of the stop block to be adjusted by the adjusting screw. When processing a relatively large bolt, it is necessary to rotate the adjusting screw to move the stop block outward, thereby widening the channel formed between the stop block and the thread rolling plate to meet the processing needs of bolts of different sizes, providing convenience for users' work.

[0015] 4. This utility model features a discharge hopper and a feeding channel. The discharge hopper is used to guide the workpiece out of the machine. After processing, the workpiece falls onto the discharge hopper and is then guided out of the machine, completing the workpiece discharge and providing convenience for the user. The feeding channel guides the feeding of the workpiece. After the user places the workpiece into the feeding channel, it will enter the machine under the guidance of the feeding channel and then be pushed to the processing position by the push block.

[0016] 5. By setting a limiting slide bar, the limiting slide bar will slide synchronously on the mounting frame when the connecting block moves. In this way, the limiting slide bar can limit the connecting block, ensuring the stability of the moving operation of the connecting block and the push rod, and providing convenience for users.

[0020] The following will refer to the appendix in the embodiments of this utility model. Figures 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0021] A flange bolt forming thread rolling machine includes a worktable 1. A mounting frame 2 is fixedly installed on one side of the top of the worktable 1. A base 14 is fixedly installed on one side of the top of the worktable 1. A cam 9 is provided through the top of one side of the base 14. A fixing frame 7 is fixedly connected to one side of the base 14. A push arm 13 adapted to the cam 9 is rotatably installed on the top of the fixing frame 7. A push rod 15 is movably installed at one end of the push arm 13. The push rod 15 is slidably installed on the mounting frame 2. A return spring 16 is sleeved on the surface of the push rod 15. The two ends of the return spring 16 are fixedly connected to the push rod 15 and the mounting frame 2, respectively. A connecting block 17 located outside the mounting frame 2 is fixedly connected to one end of the push rod 15. A push block 18 slidably installed on the mounting frame 2 is fixedly installed on one side of the connecting block 17.

[0022] This utility model adopts a structural design that can automatically push the bolt blank into the machine. The blank can be delivered outside the machine, and then the mechanical structure will automatically push the bolt blank to the thread rolling station. This avoids injury to the fingers from contact with moving parts, improves the speed of bolt blank delivery, increases the efficiency of flange bolt thread rolling, improves the safety of the user's work, and provides convenience for the user's work.

[0023] The specific working process is as follows: First, the workpiece is pushed to the position of the thread rolling plate 5 by the pusher block 18. Then, the thread rolling plate 5 rolls threads on the bolt blank. Specifically, during operation, the stepper motor 12 starts, and the stepper motor 12 drives the synchronous pulley 10 to rotate through the synchronous belt and synchronous pulley. The synchronous pulley 10 drives the gear 11, the gear 11 drives the gear 8 to rotate, and the gear 8 drives the cam 9 to rotate. It should be noted that one side surface of the cam 9 is uneven and it is in an eccentric working state. Then, the cam 9 pushes the push arm 13 to rotate on the fixed frame 7. The corresponding end of the fixed frame 7 swings outward, and the end of the push arm 13 away from the cam 9 pushes the push rod 15 to slide into the machine. At the same time, the push rod 15 drives the connecting block 1. 7. Move outward on the opposite side of the machine, while push rod 15 presses the return spring 16. Then, connecting block 17 will drive push block 18 to move outward. During this process, the workpiece in the feed channel 24 will fall next to push block 18. After cam 9 rotates one revolution, the protruding part of cam 9 will move away from push arm 13, and the end of push arm 13 will contact the concave part of cam 9. At this time, the return spring 16 will push rod 15 outward, and push rod 15 will pull back connecting block 17. At the same time, connecting block 17 will pull back push block 18. Then push block 18 will push the workpiece towards thread rolling plate 5. During this process, cam 9 is driven to rotate by gear 8. Gear 8 will push sliding block 4 in the guide rail 3 through connecting arm 6. As the sliding block 4 moves, the thread rolling plate 5 mounted on it also moves along with it. With the cooperation of the push block 18 and the stop block 20, the thread rolling plate 5 rolls threads on the surface of the workpiece. It should be noted that a channel is formed between the thread rolling plate 5 and the push block 18 for the workpiece to pass through, and a channel is formed between the stop block 20 and the thread rolling plate 5 for the workpiece to move adaptively. Thus, with the cooperation of the thread rolling plate 5, the push block 18, and the stop block 20, the thread rolling plate 5 rolls threads on the workpiece while simultaneously moving the workpiece towards the discharge hopper 23. The workpiece falls into the discharge hopper 23 after leaving the thread rolling plate 5, the push block 18, and the stop block 20, completing the discharge process. The guide rail 3 limits the movement of the sliding block 4 and also provides support for the thread rolling plate 5. The limiting function is as follows: after the work is completed, the connecting arm 6, driven by gear 8, will pull the sliding block 4 back, and the thread rolling plate 5 will also return to its original position along with the sliding block 4. At this time, the push block 18 will also move outward to make room for the next workpiece to pass through. Then, the push block 18 will send the workpiece back to the thread rolling plate 5, and the thread rolling plate 5 will move again to perform thread rolling on the workpiece. This cycle is repeated to achieve a fast and continuous working mode, improve the speed and efficiency of flange bolt thread rolling, and provide convenience for users. When the connecting block 17 moves, the limiting slide rod 19 will also move along with the connecting block 17 in the mounting frame 2, thus providing limiting support for the push rod 15 and the connecting block 17.To ensure the stability of the push rod 15 and connecting block 17 during movement, it should be noted that the position of the stop block 20 can also be adjusted by adjusting screw 21. When processing larger bolts, the adjusting screw 21 needs to be rotated to move the stop block 20 outwards, widening the channel between the stop block 20 and the thread rolling plate 5. This accommodates the processing needs of bolts of varying sizes, providing convenience for users. Therefore, a structural design that automatically pushes the bolt blank into the machine is adopted. The blank can be fed outside the machine, and then automatically pushed to the thread rolling station by a mechanical structure. This avoids injury from finger contact with moving parts, increases the speed of bolt blank feeding, improves the efficiency of flange bolt thread rolling, enhances user safety, and provides convenience for users.

[0024] A stepper motor 12 is fixedly installed on one side of the workbench 1. A second synchronous pulley is fixedly installed on the output shaft of the stepper motor 12. A first synchronous pulley 10 is rotatably installed on one side of the base 14. The first synchronous pulley 10 and the second synchronous pulley are connected by a synchronous belt. A second gear 11 located inside the base 14 is rotatably installed on one end of the first synchronous pulley 10. A first gear 8 meshing with the second gear 11 is fixedly installed on one end of the cam 9. A connecting arm 6 is movably installed on one side of the first gear 8. A sliding block 4 is movably installed on the end of the connecting arm 6 away from the first gear 8. A guide rail 3 is fixedly installed on one side of the top of the mounting bracket 2. The sliding block 4 is slidably installed inside the guide rail 3. A thread rolling plate 5 is detachably installed on one side of the sliding block 4.

[0025] Specifically, the setup includes guide rail 3, sliding block 4, thread rolling plate 5, connecting arm 6, gear 8, synchronous pulley 10, gear 11, and stepper motor 12. During operation, stepper motor 12 starts, driving synchronous pulley 10 via a synchronous belt and synchronous pulley. Synchronous pulley 10 drives gear 11, which in turn drives gear 8. Gear 8, through connecting arm 6, pushes sliding block 4 to slide within guide rail 3. Thread rolling plate 5, mounted on sliding block 4, also moves along with it. Then, with the cooperation of push block 18 and stop block 20, thread rolling plate 5 rolls threads on the surface of the workpiece. It should be noted that a channel is formed between thread rolling plate 5 and push block 18 for the workpiece to pass through, and a channel is formed between stop block 20 and thread rolling plate 5 for the workpiece to move adaptively. Thus, with the cooperation of thread rolling plate 5, push block 18, and stop block 20, threads are rolled... While the thread rolling plate 5 rolls threads on the workpiece, it also moves the workpiece towards the discharge hopper 23 until the workpiece leaves the thread rolling plate 5, the push block 18, and the stop block 20. The workpiece then falls into the discharge hopper 23 and is discharged. The guide rail 3 can limit the movement of the sliding block 4 and also limit the thread rolling plate 5. After this operation is completed, the connecting arm 6, driven by the gear 8, will pull the sliding block 4 back. At the same time, the thread rolling plate 5 will also return to its original position along with the sliding block 4. At this time, the push block 18 will also move outward to make room for the next workpiece to pass through. Then, the push block 18 will send the workpiece to the thread rolling plate 5 again, and the thread rolling plate 5 will move again to perform thread rolling on the workpiece. This cycle is repeated to achieve a fast and continuous working mode, improve the speed and efficiency of flange bolt thread rolling, and provide convenience for users.

[0026] A stop 20 located on one side of the push block 18 is slidably installed on one side of the top of the mounting bracket 2. An adjusting screw 21 is rotatably installed on one side of the stop 20. A protective shell 22 is fixedly installed on one side of the top of the workbench 1. The adjusting screw 21 is threaded onto the protective shell 22.

[0027] Specifically, the settings of the stop block 20, adjusting screw 21, and protective shell 22 are as follows: the position of the stop block 20 can also be adjusted by adjusting screw 21. When the bolt to be processed is relatively large, it is necessary to rotate adjusting screw 21 to move the stop block 20 outward, thereby expanding the channel formed between the stop block 20 and the thread rolling plate 5 to meet the processing needs of bolts of different sizes, providing convenience for users' work.

[0028] A discharge hopper 23 is fixedly installed on one side of the protective shell 22, and a feeding channel 24 is fixedly installed on one side of the top of the mounting frame 2.

[0029] Specifically, the discharge hopper 23 and the feeding channel 24 are designed as follows: the discharge hopper 23 is used to guide the workpiece out of the machine. After processing, the workpiece will fall onto the discharge hopper 23 and then be sent out of the machine under the guidance of the discharge hopper 23, thus completing the workpiece discharge and providing convenience for the user's work. The feeding channel 24 is used to guide the feeding. After the user puts the workpiece into the feeding channel 24, it will enter the machine under the guidance of the feeding channel 24 and then be pushed to the processing position by the push block 18.

[0030] A limiting slide rod 19 is provided through one side of the mounting bracket 2, and one end of the limiting slide rod 19 is fixedly installed on the connecting block 17.

[0031] Specifically, the limiting slide bar 19 is set so that when the connecting block 17 moves, it will simultaneously slide on the mounting bracket 2. In this way, the limiting slide bar 19 can limit the connecting block 17, ensuring the stability of the moving operation of the connecting block 17 and the push rod 15, and providing convenience for the user's work.

[0032] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
