[0002] Metal fasteners are mechanical parts made of metal materials, mainly used to connect and fix two or more components to form a whole. They are widely used in many fields such as industry, construction, and daily life. However, traditional metal fastener cutting devices still have defects.

[0003] Traditional metal fastener cutting equipment has low processing efficiency and mostly adopts a single-station processing mode, which can only cut a single workpiece at a time. After completing the cutting of a workpiece, manual loading, positioning, clamping, and restarting the equipment are required. The process is cumbersome and time-consuming, making it difficult to meet the needs of large-scale production. At the same time, the manual loading, unloading, and positioning process is easily affected by factors such as the operator's proficiency and fatigue state, resulting in operational errors and high scrap rates.

[0004] Traditional devices are usually designed for workpieces of specific specifications. When metal fasteners of different sizes and shapes need to be processed, it is often necessary to replace a large number of tooling fixtures or even equipment. The equipment adjustment time is long and the cost is high, making it difficult to adapt to various production needs. Summary of the Invention

[0019] The present invention preferably provides a multi-station cutting device for the production of metal fasteners. It has the following beneficial effects:

[0020] 1. This multi-station cutting device for the production of metal fasteners is equipped with an annular frame and a conveying mechanism. Once the motor is started, it drives the drive shaft to rotate, and the conveyor roller on the outer surface of the drive shaft rotates accordingly, thereby driving the conveyor belt to move in a cycle along the annular frame. The placement mechanism fixedly installed on the top of the conveyor belt follows the conveyor belt through different areas such as the loading station, cutting station, and unloading station. Compared with traditional single-station or linear processing equipment, this annular circulation conveying structure realizes continuous operation of multiple stations, eliminating the need for frequent manual handling of workpieces, greatly improving the processing efficiency of metal fasteners, reducing processing time, and at the same time reducing labor intensity, meeting the needs of large-scale industrial production.

[0021] 2. The multi-station cutting device for the production and manufacturing of metal fasteners places the metal fasteners on the turntable through the setting of the placement mechanism. The clamping plate automatically clamps the workpiece under the action of the fixing spring and the clamping spring. The second motor is started to drive the rotating shaft and the turntable to rotate. The turntable drives the workpiece to rotate. The roller at the end of the clamping plate rolls in the ring groove to ensure the stability of the rotation process. The rotating part can enable the workpiece to achieve multi-angle rotation during the processing to meet the cutting requirements. The clamping part automatically clamps the workpiece through the spring structure, and the inclined clamping plate can generate centripetal clamping force when the workpiece rotates. At the same time, the roller reduces the rotational friction. The placement mechanism ensures the positioning accuracy of the workpiece during the cutting process, avoids processing errors caused by loosening of the workpiece, and thus improves product quality and processing accuracy.

[0022] 3. The multi-station cutting device for the production of metal fasteners is equipped with a cutting mechanism. When the placement mechanism transports the workpiece to the cutting area, the cylinder is started, the telescopic rod drives the pressure block to descend, the electric push rod pushes the arc plate, and the clamping block drives the tool to feed toward the workpiece under the guidance of the clamping slot for cutting. After the processing is completed, the electric push rod retracts, the tool retracts, and the cylinder drives the pressure block to rise and reset. Through the cooperation of the cylinder and the electric push rod, the cutting process is automatically controlled, and the cutting parameters can be adjusted according to different processing requirements, thereby improving the cutting efficiency and processing accuracy, while reducing the scrap rate and ensuring the stability of product quality.

[0023] 4. This multi-station cutting device for the production of metal fasteners is equipped with a protective shell. After the placement mechanism transports the workpiece into the cutting area, the cutting operation is carried out inside the protective shell. The generated metal debris is blocked inside the shell, effectively protecting the personal safety of the operator and reducing the risk of injury to the operator by debris.

[0024] 5. The multi-station cutting device for the production of metal fasteners is equipped with a cutting piece. The clamping block and the arc plate are clamped through a clamping slot, and the tool is fixedly installed on the clamping block. When the tool needs to be replaced, the clamping block is manually pulled out of the clamping slot, the old tool is removed, and the new tool is installed before the clamping block is reinserted into the clamping slot. The limiting piece and the inner curved surface of the arc plate are squeezed and limited to ensure a stable installation. The cutting piece realizes the rapid disassembly and installation of the tool, which is convenient for replacing tools of different types and specifications, thereby improving the versatility of the equipment.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] The first embodiment, as Figures 1 to 6 As shown, the present invention provides a technical solution: a multi-station cutting device for producing metal fasteners, comprising:

[0039] The annular frame 1 and the conveying mechanism 2 fixedly mounted on the top of the annular frame 1 can realize the circular conveyance of the workpiece, so that the workpiece can enter the cutting area for processing in sequence, ensuring continuous operation of multiple stations. The inner and outer sides of the annular frame 1 are fixedly mounted with mounting plates 4, and the top of the mounting plate 4 is fixedly mounted with a protective shell 5. The protective shell 5 prevents metal debris generated during the cutting process from splashing, thereby protecting the safety of the operator;

[0040] The conveying mechanism 2 includes a motor 21 and a transmission shaft 22. The motor 21 is fixedly mounted on the outer surface of the annular frame 1 through a bracket. The transmission shaft 22 is rotatably mounted inside the annular frame 1. The transmission shaft 22 passes through the annular frame 1 and extends to both sides thereof. One end of the transmission shaft 22 is fixedly connected to the output end of the motor 21. A conveying roller 23 is fixedly mounted on the outer surface of the transmission shaft 22. A conveyor belt 24 is drive-mounted on the outer surface of the conveying roller 23.

[0041] The placing mechanism 3 is installed on the top of the conveying mechanism 2. The placing mechanism 3 is used to place multiple metal fasteners at the same time and rotate the workpiece. The conveying mechanism 2 conveys the placing mechanisms 3 at multiple stations to enter the cutting area.

[0042] The placement mechanism 3 includes a work box 31, a placement groove 32 is provided on the top of the work box 31, and the placement groove 32 is used to place metal fasteners. The inner wall of the placement groove 32 is provided with an annular groove 33. When the workpiece rotates, the annular groove 33 plays a guiding and limiting role to ensure the stability of the workpiece rotation. A rotating member 34 is rotatably installed inside the placement groove 32, and the rotating member 34 drives the workpiece to rotate. A fixed plate 35 is fixedly installed in the middle of the bottom of the work box 31;

[0043] Preferably, the fixed disk 35 is fixedly installed on the top of the conveyor belt 24, and the fixed disk 35 is evenly distributed on the top of the conveyor belt 24. The output end of the motor 21 drives the transmission shaft 22 to rotate, and the transmission shaft 22 causes the conveyor roller 23 to drive the conveyor belt 24 to move, thereby realizing the cyclic movement of the placement mechanism 3 on the annular frame 1, thereby transporting the workpiece on the placement mechanism 3 to different workstations;

[0044] The cutting mechanism 6 is installed at the top of the inner cavity of the protective shell 5. The cutting mechanism 6 is arranged directly above the placement mechanism 3. The cutting mechanism 6 cuts multiple metal fasteners placed on the placement mechanism 3.

[0045] The second embodiment, based on the first embodiment, see Figure 7 and Figure 8 As shown, the rotating member 34 includes a second motor 341, which is fixedly mounted on the top of the inner cavity of the working box 31 through a bracket, and the output end of the second motor 341 is fixedly connected to a first rotating shaft 342, which passes through the working box 31 and extends to its top, and a turntable 343 is fixedly mounted on the top of the first rotating shaft 342, and the turntable 343 is rotatably mounted inside the placement slot 32, and a clamping member 344 is mounted on the top of the turntable 343. The turntable 343 rotates under the drive of the first rotating shaft 342, thereby driving the workpiece clamped by the clamping member 344 to rotate;

[0046] Preferably, the number of the clamping members 344 is five, and the five clamping members 344 are evenly distributed along the axis of the rotating disk 343, and fixed springs 345 are fixedly connected between the clamping members 344;

[0047] The cam 3442 is fixedly mounted on the top of the fixing plate 35, and an arc-shaped sliding frame 3442 is slidably mounted on the top of the sliding rail 3441. A rotating rod 3443 is fixedly mounted on the inner side of the arc-shaped sliding frame 3442. A clamping plate 3444 is slidably mounted on the outer surface of the rotating rod 3443. The clamping plate 3444 is tilted and is used to directly clamp the workpiece. The tilted design can generate a centripetal force when the workpiece rotates, making the clamping more stable and preventing the workpiece from loosening during the rotation process. The fixing spring 345 is fixedly connected to the outer surface of the clamping plate 3444. The fixing spring 345 provides a centripetal pulling force for the clamping plate 3444, so that the clamping plate 3444 can automatically clamp the workpiece.

[0048] Preferably, a second rotating shaft 3445 is rotatably mounted on the end of the clamping plate 3444, and rollers 3446 are fixedly mounted on both ends of the second rotating shaft 3445. The rollers 3446 are arranged inside the annular groove 33. When the workpiece rotates, the rollers 3446 roll in the annular groove 33, reducing the friction between the clamping plate 3444 and the working box 31, thereby ensuring smooth rotation of the workpiece.

[0049] Preferably, a clamping spring 3447 is fixedly installed on the outer curved surface of the arc-shaped sliding frame 3442, and the other end of the clamping spring 3447 is fixedly installed on the inner wall of the placement groove 32. The clamping spring 3447 assists the fixing spring 345 in providing clamping force during the process of clamping the workpiece.

[0050] The third embodiment, based on the first and second embodiments, see Figures 9 to 11 As shown, the cutting mechanism 6 includes a cylinder 61, which is fixedly mounted on the top of the protective housing 5. The telescopic end of the cylinder 61 is fixedly connected to a telescopic rod 62, which passes through the protective housing 5 and extends into the interior thereof. A pressure block 63 is fixedly mounted on the bottom of the telescopic rod 62. A mounting groove 64 is provided on the lower surface of the pressure block 63. The mounting groove 64 is equidistant from the placement groove 32. A protective pad 65 is fixedly mounted inside the mounting groove 64. Cutting members 66 are mounted on both sides of the inner wall of the mounting groove 64. , guide pillars 67 are fixedly installed at the four corners of the top of the pressure block 63, and the other end of the guide pillar 67 is fixedly connected to the top of the inner cavity of the protective shell 5. The cylinder 61 drives the telescopic rod 62 to move up and down through the telescopic movement of the telescopic end, thereby realizing the lifting and lowering of the pressure block 63 and the cutting piece 66, so that the cutting piece 66 can approach or move away from the workpiece for cutting operations. The guide pillars 67 play a guiding and stabilizing role in the process of the pressure block 63 moving up and down, preventing the pressure block 63 from tilting or deflecting during movement, thereby ensuring the stability and processing accuracy of the cutting mechanism 6;

[0051] The cutting member 66 includes an electric push rod 661 and a clamping block 664. The electric push rod 661 is fixedly installed on the inner wall of the installation groove 64. The other end of the electric push rod 661 is fixedly installed with an arc plate 662. The surface of the arc plate 662 is provided with a clamping groove 663. The clamping block 664 is clamped and adapted to the clamping groove 663. A tool 665 is fixedly installed on one side of the clamping block 664 near the axis of the installation groove 64. The arc plate 662 is pushed to move by the telescopic movement of the electric push rod 661, thereby driving the clamping block 664 and the tool 665 to move, thereby realizing the feeding and cutting action of the tool 665 on the workpiece. Limiting plates 666 are fixedly installed on both sides of the clamping block 664. The limiting plates 666 are squeezed and adapted to the inner curved surface of the arc plate 662. The limiting plates 666 play a limiting role in the movement of the clamping block 664, preventing the clamping block 664 from deflecting or shaking during movement, thereby ensuring the accuracy of the cutting position of the tool 665.

[0052] During use, the operator places the metal fastener to be processed between the clamping members 344 in the placement mechanism 3. At this time, the clamping plates 3444 automatically clamp the workpiece under the action of the spring force. Since the clamping plates 3444 are set at an angle, they can generate a centripetal clamping force when clamping, ensuring that the workpiece is stably fixed.

[0053] Start the motor 21, which drives the transmission shaft 22 to rotate. The conveyor roller 23 rotates along with the transmission shaft 22. The conveyor belt 24 installed on the outer surface of the conveyor roller 23 starts to move along the annular frame 1 under the drive of the conveyor roller 23. The fixed plate 35 fixed on the top of the conveyor belt 24 stably fixes the placement mechanism 3 and moves with the conveyor belt 24, so that the workpiece on the placement mechanism 3 passes through different workstations in sequence and finally enters the cutting area in the protective housing 5.

[0054] When the placement mechanism 3 enters the cutting area, the second motor 341 is activated, and the output end of the second motor 341 drives the first rotating shaft 342 to rotate. The first rotating shaft 342 drives the top turntable 343 to rotate within the placement slot 32. When the turntable 343 rotates, the clamping member 344 and the clamped workpiece rotate together. The roller 3446 rolls within the annular groove 33 on the inner wall of the placement slot 32, reducing the friction resistance of the turntable 343 during rotation, while ensuring the stability and accuracy of the rotation process.

[0055] Start the cylinder 61, the telescopic end of the cylinder 61 drives the telescopic rod 62 to move downward, and the pressing block 63 drops accordingly. The protective pad 65 acts as a buffer to prevent the pressing block 63 from causing damage to the workpiece;

[0056] The cutting member 66 starts working, the electric push rod 661 starts, pushing the curved plate 662 to move, and the clamping groove 663 on the surface of the curved plate 662 is clamped and adapted with the clamping block 664, driving the clamping block 664 to move along the inner curved surface of the curved plate 662. The limiting pieces 666 on both sides of the clamping block 664 are squeezed and adapted with the inner curved surface of the curved plate 662 to ensure that the movement process of the clamping block 664 is stable. The tool 665 is fed to the workpiece under the drive of the clamping block 664 to cut the workpiece. Since the installation slot 64 and the placement slot 32 are equidistant, multiple cutting members 66 can cut multiple workpieces at the same time, greatly improving the processing efficiency.

[0057] The guide post 67 plays a guiding and stabilizing role during the descent and ascent of the pressing block 63, ensuring that the pressing block 63 and the cutting piece 66 do not tilt or deflect when moving up and down, thereby ensuring the accuracy of the cutting position and the processing precision;

[0058] After the cutting process is completed, the electric push rod 661 contracts, driving the arc plate 662 and the clamping block 664 to move in the opposite direction, and the tool 665 returns to the initial position along with the clamping block 664. The telescopic end of the cylinder 61 drives the telescopic rod 62 to move upward, and the pressing block 63 rises and resets accordingly.

[0059] The conveyor belt 24 continues to operate, transporting the placement mechanism 3 that has completed the cutting process to the unloading station. The operator takes the processed metal fasteners out of the clamping member 344, and then puts the workpiece to be processed again to start a new round of processing cycle.
