Description

Technical Field

[0001] This application relates to the field of metal processing technology, and in particular to a nut processing apparatus. Background Technology

[0002] In the field of machinery manufacturing, nuts are a common fastener with a wide range of applications, covering many industries such as automobile manufacturing, aerospace, and construction engineering. With the continuous development of industry, the demand for nuts is increasing, and the requirements for their production efficiency and quality are also getting higher and higher. Efficient and precise nut production equipment has become a key factor in promoting the development of related industries, which can greatly improve production scale and product quality, and reduce production costs.

[0003] In related technologies, traditional nut forming processes mainly employ turning and casting. Turning involves cutting the raw material with a lathe to gradually shape the nut, while casting involves pouring molten metal into a mold and cooling it to obtain a nut blank. Casting can mass-produce nuts and is suitable for large-scale production.

[0004] However, this method has the following drawbacks: the existing nut forming process has problems such as low production efficiency and unstable forming quality. The turning process is relatively cumbersome, requiring multiple clamping and cutting, resulting in low production efficiency. Defects such as porosity and sand holes are prone to occur in the casting process, which affects the strength and precision of the nut, thus affecting the performance of the nut and reducing the reliability of the product. Utility Model Content

[0005] To address the aforementioned problems, this application provides a nut processing apparatus.

[0006] The nut processing device provided in this application adopts the following technical solution: A nut processing device for processing steel rods includes a frame, a forming mechanism, and a first transmission assembly. Both the forming mechanism and the first transmission assembly are mounted on the frame. The forming mechanism includes a cutting assembly and a stamping assembly, both installed inside the frame. The cutting assembly processes the steel rod into steel blanks. Several stamping assemblies are arranged side-by-side, each performing different processing on the steel rod. Each stamping assembly includes a push rod, a stamping rod, and a pressure rod. The frame is provided with a stamping hole, and the frame interior is provided with a first stamping channel and a second stamping channel. The stamping hole and the first stamping channel are connected. The stamping rod and the pushing rod are arranged opposite to each other. The pushing rod is slidably disposed in the stamping hole and the first stamping channel, and the stamping rod is slidably disposed in the second stamping channel. The first stamping channel and the pushing rod are provided with matching stamping structures according to processing requirements. The clamping member grips the steel billet between the stamping rod and the pushing rod. The first transmission assembly is fixedly connected to the pressure rod, and the first transmission assembly drives the pressure rod to... The stamping rod abuts against the push rod, the pressure rod pushes the stamping rod to move towards the push rod, the clamping member grips the steel billet between the push rod and the stamping rod, the stamping rod pushes the steel billet to the first stamping channel, the push rod squeezes the steel billet to form a semi-finished product, the first transmission assembly drives the pressure rod to abut against the push rod, the pressure rod pushes the push rod to move towards the stamping rod, the push rod pushes the semi-finished product out of the first stamping channel, the clamping member moves the semi-finished product to the next stamping assembly, and the first transmission assembly is a reciprocating linear motion.

[0007] By adopting the above technical solution, the cutting assembly first automatically cuts the steel rod into columnar steel blanks of a set length. Then, the clamping component transfers the blank to the first stamping assembly. The first transmission assembly drives the stamping rod to push the steel blank to the first stamping channel. Since the first stamping channel and the push rod are equipped with matching stamping structures according to processing requirements, pressure is applied to the steel blank in the first stamping channel to complete the initial shaping and form a semi-finished product. The first transmission assembly drives the pressure rod to push the push rod to further push the semi-finished product out of the first stamping channel. The semi-finished product is passed through the clamping component and multiple sets of parallel stamping assemblies in sequence to gradually complete the forming, punching and end face flattening of the nut. In this process, the need for multiple clamping and cutting is reduced, the processing flow is greatly simplified and the production efficiency is improved. At the same time, it ensures the stability and consistency of the stamping process, effectively reduces defects such as porosity and sand holes that are prone to occur in the casting process, and guarantees the strength and precision of the nut. Meanwhile, the first transmission component is a reciprocating linear motion, which ensures that the push rod and the stamping rod are reciprocating, so that the push rod and the stamping rod have the same working rhythm.

[0008] Preferably, the cutting assembly is located near the first stamping assembly that processes the steel billet, and the cutting assembly includes a cutting blade and a drive cylinder, with the cutting blade fixedly connected to the drive cylinder.

[0009] By adopting the above technical solution, the cutting component is arranged near the first stamping component that processes the steel billet to ensure efficient connection of the processing flow. The cutting tool is fixedly connected to the piston rod of the drive cylinder. The extension and retraction of the piston rod directly drives the cutting tool to perform fast and precise cutting action, thereby automatically cutting the continuous steel rod into steel billets of a set length, providing qualified billets for subsequent stamping processing steps.

[0010] Preferably, the first transmission assembly includes a base, a rocker arm, an eccentric wheel, and a first drive motor. The base is fixed to the inner wall of the frame. The rocker arm includes a sliding part and a transmission part. The transmission part is vertically fixed to the sliding part and the sliding part is slidably disposed on the base. The end of the eccentric wheel is provided with a sliding seat. The first drive motor is fixed to the base. The output shaft of the first drive motor is coaxially fixed with the eccentric wheel. The transmission part is provided with a sliding groove, and the sliding seat is slidably disposed in the sliding groove.

[0011] By adopting the above technical solution, the base is firmly fixed to the inner wall of the frame, providing reliable support for the entire first transmission assembly. The transmission part is vertically fixed to the sliding part, which is slidably mounted on the base to ensure that the rocker arm can move smoothly and accurately. The first drive motor is fixed on the base and coaxially fixed with the seat of the eccentric wheel, providing a power source for the entire first transmission assembly. A sliding seat is fixedly mounted at the end of the eccentric wheel, and the transmission part of the rocker arm is correspondingly mounted with a sliding groove. The sliding seat slides in the sliding groove. When the first drive motor drives the eccentric wheel to rotate, it drives the sliding seat to slide in the sliding groove. The sliding seat in the sliding groove drives the sliding part to slide back and forth on the base to perform reciprocating motion. The rotational motion of the eccentric wheel can be efficiently and smoothly converted into the sliding motion of the rocker arm on the base, thereby realizing the functions of power transmission and motion conversion.

[0012] Preferably, a second transmission assembly is provided between the first transmission assembly and the pressure rod. The second transmission assembly includes a transmission arm, a first drive shaft, and a second drive shaft. Two transmission arms are provided. One end of the first transmission arm is coaxially fixed to the first drive shaft, and the other end of the first transmission arm is coaxially fixed to the rocker arm. The first drive shaft is fixedly provided with a first mounting base, and the pressure rod is fixed to the mounting base. One side of the second transmission arm is coaxially fixed to the side of the rocker arm away from the first mounting base, and the other side of the second transmission arm is coaxially fixed to the second drive shaft. The second drive shaft is fixedly provided with a second mounting base, and the pressure rod is fixed to the second mounting base. The ends of the first and second drive shafts away from the rocker arm are rotatably supported on the frame. A first reset member is provided between the transmission arm coaxially fixed to the first drive shaft and the frame. One end of the first reset member is fixedly connected to the frame, and the other end of the first reset member is fixedly connected to the transmission arm.

[0013] By adopting the above technical solution, when the first drive motor starts, the rotational motion of the first drive motor is first transmitted to the eccentric wheel, and then to the rocker arm. The rocker arm reciprocates, and the reciprocating motion of the rocker arm is transmitted to the first drive shaft through the transmission arm. The first drive shaft drives the first mounting seat and the pressure rod to reciprocate. The second transmission arm then transmits the rotational motion of the rocker arm to the second drive shaft. The second drive shaft drives the second mounting seat and the pressure rod to reciprocate as well. The first transmission assembly makes the pressure rod that abuts against the stamping rod and the pressure rod that abuts against the push rod form the same working rhythm. The pressure rod pushes the first stamping rod to push the steel billet to the first stamping channel for processing. After processing, the pressure rod pushes the stamping rod to push the steel billet out of the first stamping channel. The reset component reduces the rotational inertia of the transmission arm driving the first and second drive shafts and limits the range of reciprocating rotational motion, thereby ensuring the efficiency and consistency of nut punching processing.

[0014] Preferably, the first stamping channel is provided with a second reset member, one end of which is fixedly connected to the first stamping channel, and the other end of which is fixedly connected to the push rod.

[0015] By adopting the above technical solution, during the stamping process, the push rod is pushed away from the first stamping channel by the force of the pressure rod. When the pressure rod is removed, the second reset component can use elastic potential energy to assist the push rod in quickly resetting. This not only reduces the time required for the push rod to reset and improves the efficiency of the entire stamping process, but also ensures that the push rod can be accurately reset every time, maintaining the stability and consistency of the stamping process.

[0016] Preferably, the system also includes a correction assembly, which includes a worktable and correction wheels. Several correction wheels are provided. The worktable is fixedly connected to the frame. Several correction wheels are rotatably supported on the worktable. Several correction wheels are arranged opposite each other to form correction channels. A steel rod is located between the correction channels. The correction wheels and the steel rod are in frictional contact.

[0017] By adopting the above technical solution, the straightening assembly consists of a worktable and multiple straightening wheels. These straightening wheels are rotatably mounted on the worktable and form a certain straightening channel. The steel rod passes through the straightening channel. During the steel rod conveying process, the straightening wheels maintain frictional contact with the steel rod. When the steel material is slightly skewed, the straightening wheels apply a lateral straightening force to the steel rod through rotational motion and friction with the steel rod, guiding the steel rod to gradually return to the correct conveying path. This ensures that even if the steel rod itself has a certain degree of bending or twisting, it can be effectively straightened when passing through the straightening assembly, ensuring that the steel material can enter the subsequent processing stage in a stable state. This not only improves the conveying accuracy of the steel rod and reduces processing errors and equipment jamming caused by steel material skew, but also significantly improves the quality and efficiency of nut punching processing, reduces the scrap rate, and thus improves the stability and reliability of the entire nut production line.

[0018] Preferably, it also includes an auxiliary traction assembly, which is mounted on the frame. The auxiliary traction assembly is provided in several groups. The auxiliary traction assembly includes a traction wheel and a second drive motor. There are two traction wheels, which are vertically distributed. The output shaft of the second drive motor is coaxially fixed with the traction wheels. The steel rod is located between the two traction wheels, and the traction wheels pull the steel rod into the frame.

[0019] By adopting the above technical solution, two traction wheels are arranged vertically to form a clamping structure. The steel rod passes between the two wheels, and the second drive motor directly drives the traction wheels to rotate synchronously. The friction force is used to continuously and smoothly feed the steel rod into the machine frame, effectively solving the problems of slippage, deviation, or jamming that easily occur during the conveying process. This ensures the continuity and stability of the steel rod feeding. At the same time, the auxiliary traction component and the straightening component work together to further ensure that the steel rod enters the subsequent processing process in a straight and stable state. This lays the foundation for the precise cutting of the subsequent cutting component and the efficient processing of the stamping component, thereby significantly improving the automation level, processing efficiency, and product quality of the entire nut production line.

[0020] Preferably, a third transmission assembly is provided between the two traction wheels. The third transmission assembly includes a belt and a pulley. The pulley is coaxially fixed with the two traction wheels, and the belt is sleeved on the pulley.

[0021] By adopting the above technical solution, the pulley is coaxially fixed with the two traction wheels, and the belt is sleeved on the pulley. When the second drive motor drives one of the traction wheels to rotate, the pulley rotates at the same time. Since the belt is sleeved on the pulley, it drives the other pulley to rotate, which can ensure that the other traction wheel rotates synchronously at the same speed and direction. This effectively reduces problems such as slippage, offset or tensile deformation of the steel rod caused by the inconsistent speed of the two traction wheels, and ensures that the steel rod can be fed into the frame at a stable and uniform speed.

[0022] Preferably, the feeding assembly includes a feeding channel and a hopper, wherein the feeding channel is connected to the hopper.

[0023] By adopting the above technical solution, the hopper can hold a certain amount of finished nuts, while the feeding channel guides the finished nuts from the forming mechanism into the hopper through the guiding structure of the feeding channel, ensuring that the finished nuts will not scatter or get stuck during the conveying process, and reducing the tedious operation of frequent manual cleaning and sorting.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. After the cutting assembly automatically cuts the steel rod into columnar steel blanks of a set length, the clamping component picks them up and transfers them to the multi-station stamping components arranged in parallel. Each stamping component synchronously drives the pressure rod through the first transmission component to push the stamping rod, so that the steel blank is squeezed in the first stamping channel to form a semi-finished product. The shaping, punching and end face flattening processes are completed in the first stamping channel. The pressure rod and the push rod abut against each other, and the pressure rod applies pressure to the push rod, so that the semi-finished product leaves the first stamping channel. The clamping component circulates and transfers the steel blank to the subsequent stamping components. Finally, the nut processing is completed by continuous stamping through multiple stamping components. 2. The first transmission component uses an eccentric wheel to drive the rocker arm to achieve reciprocating motion conversion. The base is fixed to the inner wall of the frame as a support base. The output shaft of the first drive motor is coaxially connected to the eccentric wheel seat. When the motor drives the eccentric wheel to rotate, the sliding seat fixed at the end of the eccentric wheel slides along the sliding groove of the rocker arm transmission part, forcing the sliding part to make linear reciprocating motion on the base. The eccentric wheel efficiently converts the rotational motion into linear reciprocating motion, ensuring that the stamping rod and the push rod obtain a smooth bidirectional force action, effectively ensuring the synchronization and cycle consistency of the processing. 3. Several straightening wheels on the workbench are arranged in a relatively rotating manner to form a straightening channel. When the steel rod passes through the straightening channel, the straightening wheels maintain rolling friction contact with the steel surface, applying a continuous lateral straightening force to the steel. When the steel deviates radially, the straightening wheels convert the deviation into an axial component force through rotational motion, dynamically adjusting the steel's trajectory. This gradually straightens the bent steel during the conveying process, ensuring that the steel enters the subsequent process in a stable state. This effectively reduces processing errors caused by the bending of raw materials, reduces equipment jamming, and significantly improves the processing accuracy, operational continuity, and product qualification rate of the nut production line.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] This application discloses a nut processing apparatus. (Refer to...) Figure 1and Figure 2 A nut processing device includes a frame 1, a forming mechanism, a first transmission component 3, a straightening component 5, an auxiliary traction component 6, and a feeding component 7. The forming mechanism, the first transmission component 3, the straightening component 5, the auxiliary traction component 6, and the feeding component 7 are all mounted on the frame 1. The first transmission component 3 provides driving force to the forming mechanism. The straightening component 5 and the auxiliary traction component 6 pull the steel rod to the forming mechanism. The forming mechanism is used to process the steel rod to form a finished nut. The feeding component 7 is used to discharge the processed nut. This achieves efficient, precise, and stable processing of the steel rod, forming a complete nut processing flow, reducing manual operation, and lowering the possibility of error accumulation.

[0033] Specifically, in this embodiment, the processing steps are described as follows: First, the steel rod enters the straightening component 5. The straightening component 5 includes a workbench 51 and straightening wheels 52. Several straightening wheels 52 are provided. In this embodiment, five straightening wheels 52 are provided. The five straightening wheels 52 rotate and are supported on the workbench 51 and are arranged opposite each other to form a straightening channel. The steel rod is located in the straightening channel. The straightening wheels 52 are in frictional contact with the steel rod, which can effectively straighten the shape of the steel rod, making the steel rod flatter and facilitating subsequent processing.

[0034] Furthermore, the steel rod enters the auxiliary traction assembly 6 through the straightening assembly 5. Specifically, the auxiliary traction assembly 6 is installed on the frame 1, and several of them are provided. In this embodiment, there are two sets of auxiliary traction assemblies 6, which are arranged horizontally. The auxiliary traction assembly 6 includes a traction wheel 61 and a second drive motor 62. There are two traction wheels 61, which are vertically distributed. The output shaft of the second drive motor 62 is coaxially fixed with the traction wheels 61. The steel plate coil is located between the two traction wheels 61. The traction wheels 61 pull the steel rod to the forming mechanism. The second drive motor 62 is set as a stepper motor. The stepper motor can more accurately control the rotation angle and speed, thereby improving the processing accuracy.

[0035] Meanwhile, a third transmission assembly 10 is provided between the two traction wheels 61. The third transmission assembly 10 includes a belt 101 and a pulley 102. The pulley 102 is coaxially fixed to the two traction wheels 61, and the belt 101 is sleeved on the pulley 102. This ensures that the two traction wheels 61 rotate synchronously and improves the stability of traction.

[0036] Reference Figure 3Furthermore, the forming mechanism includes a cutting assembly 21 and a stamping assembly 22. The cutting assembly 21 is located near the first stamping assembly 22 that processes the steel and includes a cutting blade 211 and a drive cylinder 212. The cutting blade 211 is fixedly connected to the drive cylinder 212. The cutting blade 211 has a sharp blade shape and good cutting performance. The drive cylinder 212 can provide stable power to the cutting blade 211, so that the cutting blade 211 can accurately cut the steel rod into steel billets.

[0037] Furthermore, several stamping components 22 are provided. In this embodiment, five stamping components 22 are provided, arranged side by side, for different processing of the steel rod. The stamping component 22 includes a push rod 221, a stamping rod 222, a clamping member 224, and a pressure rod 223. The frame 1 is provided with a stamping hole 11, a first stamping channel 12, and a second stamping channel 13. The stamping hole 11 and the first stamping channel 12 are interconnected. The push rod 221 is slidably disposed in the stamping hole 11 and the first stamping channel 12, and the stamping rod 222 is slidably disposed in the second stamping channel 13. The stamping rod 222 is disposed opposite to the push rod 221. The push rod 221 is cylindrical. The push rod 221 and the first stamping channel 12 are provided with matching stamping structures according to processing requirements.

[0038] Reference Figure 5 Meanwhile, the clamping component 224 is configured as a gripper cylinder. Five clamping components 224 are fixed on the first transmission assembly 3. The first transmission assembly 3 performs reciprocating translational motion between multiple stamping assemblies 22 to ensure that the gripper cylinder accurately clamps and transfers the steel billet between different stamping assemblies 22, thereby completing the continuous processing of the steel billet.

[0039] Furthermore, the clamping member 224 clamps the steel billet to the stamping assembly 22. The first transmission assembly 3 drives the pressure rod 223 to abut against the stamping rod 222. The pressure rod 223 pushes the stamping rod 222, and the stamping rod 222 pushes the steel billet to the first stamping channel 12. Since the push rod 221 and the first stamping channel 12 are set in a shape suitable for stamping, the stamping rod 222 stamps the steel billet into a semi-finished product. The first transmission assembly 3 drives the pressure rod 223 to abut against the push rod 221. The pressure rod 223 applies pressure to the push rod 221, causing the push rod 221 to move toward the stamping rod 222, pushing the steel billet out of the first stamping channel 12. Then, the clamping member 224 moves the steel billet to the next stamping assembly 22.

[0040] Reference Figure 4Furthermore, the first transmission assembly 3 includes a base 31, a rocker arm 32, an eccentric wheel 33, and a first drive motor 34. The base 31 is fixed to the inner wall of the frame 1, serving as support and positioning. The rocker arm 32 includes a sliding part 321 and a transmission part 322. The transmission part 322 is vertically fixed to the sliding part 321, and the sliding part 321 is slidably disposed on the base 31. A sliding seat 35 is provided at the end of the eccentric wheel 33. The first drive motor 34 is fixed to the base 31, and the first drive motor 34 outputs power to the machine. The output shaft passes through the base 31 and is coaxially fixed with the eccentric wheel 33. The transmission part 322 is provided with a sliding groove 3221. The sliding seat 35 is slidably disposed in the sliding groove 3221. When the first drive motor 34 rotates, it drives the eccentric wheel 33 to rotate. The rotation of the eccentric wheel 33 is converted into the reciprocating linear sliding motion of the rocker arm 32 by the sliding of the sliding seat 35 in the sliding groove 3221. The first drive motor 34 is set as a stepper motor. The stepper motor can more accurately control the rotation angle and speed, and improve the machining accuracy.

[0041] Furthermore, a second transmission assembly 4 is provided between the first transmission assembly 3 and the pressure rod 223. The second transmission assembly 4 also includes a transmission arm 41, a first drive shaft 42, and a second drive shaft 43. Two transmission arms 41 are provided. One end of the first transmission arm 41 is coaxially fixed to the first drive shaft 42, and the other end is coaxially fixed to one side of the rocker arm 32. The first drive shaft 42 is fixedly provided with a first mounting base 14, and the pressure rod 223 is fixed to the mounting base. One end of the second transmission arm 41 is coaxially fixed to the side of the rocker arm 32 away from the first drive shaft 42, and the other end of the second transmission arm 41 is coaxially fixed to the other side of the rocker arm 32 away from the first drive shaft 42. The first drive shaft 42 and the second drive shaft 43 are coaxially fixed. The second drive shaft 43 is fixedly provided with a second mounting base 15. The push rod 221 is fixed on the second mounting base 15. The ends of the first drive shaft 42 and the second drive shaft 43 away from the rocker arm 32 are rotatably supported on the frame 1. A first reset member 8 is provided between the transmission arm 41, which is coaxially fixed with the first drive shaft 42, and the frame 1. One end of the first reset member 8 is fixedly connected to the frame 1, and the other end is fixedly connected to the transmission arm 41. The first reset member 8 is set as a spring, which can restore the transmission arm to the initial position after the transmission arm 41 moves, so as to ensure the stability of processing.

[0042] In addition, the first stamping channel 12 is provided with a second reset member 9. One end of the second reset member 9 is fixedly connected to the first stamping channel 12, and the other end is fixedly connected to the push rod 221. The second reset member 9 is also set as a spring, which can make the push rod 221 return to its original position after completing the stamping action, so as to perform the next stamping.

[0043] In addition, the feeding assembly 7 includes a feeding channel 71 and a hopper 72. The feeding channel 71 is connected to the hopper 72. The hopper 72 can hold a certain amount of finished nuts, while the feeding channel 71 guides the finished nuts from the punching station into the hopper 72 through the guiding structure of the feeding channel 71. This ensures that the finished nuts will not scatter or get stuck during the conveying process, reducing the tedious operation of frequent manual cleaning and sorting.

[0044] The implementation principle of a nut processing device according to an embodiment of this application is as follows: A nut processing device achieves efficient and precise processing of steel rods through the coordinated operation of various mechanisms. A straightening component first straightens the steel rod, making its shape more regular. An auxiliary traction component pulls the steel rod to the forming mechanism. A cutting component cuts the steel rod into steel blanks. A clamping component holds the steel blanks to different stamping components, which then sequentially process the steel blanks into nuts. A first transmission component provides power to the clamping and stamping components, ensuring smooth stamping operations. A blanking component discharges the processed nuts. Compared with traditional nut processing methods, this device reduces manual operation, lowers labor intensity, improves production efficiency and processing accuracy, reduces the accumulation of processing errors, can adapt to the processing of nuts of different specifications and requirements, improves nut quality and supply stability, and promotes the development of related industries.

[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
