Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device suitable for the production of compression springs of different sizes. Background Technology

[0002] Existing cutting equipment for spring production achieves efficient spring cutting through a precise control system and powerful cutting tools. In operation, the spring is fed into the cutting area via a conveyor system, and the cutting tool, guided by the control system, precisely cuts the spring to a set length. This equipment is typically equipped with multiple sensors to monitor the spring's feed rate, cutting position, and tool status, thereby ensuring cutting accuracy and efficiency. Automated operation not only reduces human error but also significantly improves production efficiency.

[0003] Patent CN212704733U discloses a novel cutting device for producing compression springs. Specifically, the patent discloses a technical solution comprising: "a main base, a feeding trough on the top left side of the main base, multiple transmission rollers on the top of the feeding trough, a servo motor on the right side of the feeding trough, telescopic baffles above the left and right ends of the transmission rollers, an L-shaped fixing frame on the top left side of the main base, a ball screw fixedly connected to the lower right side of the L-shaped fixing frame, a ball sleeve fitted onto the outer surface of the ball screw, and a cutting device located on the lower right side of the ball sleeve." This solution effectively prevents the compression spring from shifting during cutting, avoids sharp cuts, ensures smooth cuts, and achieves high automation and cutting efficiency, effectively saving labor and reducing the risk of injury to the user.

[0004] Existing cutting devices generate a large amount of debris during the cutting of compression springs. This debris accumulation in the working area can accelerate tool wear, affecting cutting results, increasing workload, and making operation inconvenient. Furthermore, existing cutting devices typically only secure a single type of compression spring, lacking flexibility. For compression springs of different specifications and sizes, operators need to manually change the securing device or adjust the equipment, which not only wastes time but may also increase errors and safety risks during operation.

[0005] Therefore, we propose a cutting device suitable for the production of compression springs of different sizes. Utility Model Content

[0030] The cleaning components include a dust collection box 8, a suction pipe 9, and a suction cup 10. The dust collection box 8 is fixedly installed on one side of the first telescopic rod 4. The bottom of the dust collection box 8 is fixedly connected to the suction pipe 9 to ensure that debris and dust in the cutting area can be removed in time during the cutting process. The dust collection box 8 sucks up the waste generated during cutting through the suction pipe 9 to keep the working area clean and improve cutting efficiency. The end of the suction pipe 9 away from the dust collection box 8 is fixedly connected to the suction cup 10. The side of the suction cup 10 away from the suction pipe 9 is close to the cutting blade 6.

[0031] A second motor 11 is fixedly installed on both sides of the support frame 2, providing rotational power to drive the rotating shaft 12 to rotate. The output end of the second motor 11 is coaxially fixedly connected to the rotating shaft 12 via a coupling. A support plate 13 is fixedly installed on the side of the support frame 2 near the rotating shaft 12. The end of the rotating shaft 12 away from the second motor 11 is rotatably connected to the top of the support plate 13 via a bearing. A gear 14 is coaxially fixedly connected to the outer circumference of the rotating shaft 12. A half gear 15 is provided on one side of the gear 14. The half gear 15 is rotatably connected to one side of the support frame 2 via a bearing. The teeth of the gear 14 and the half gear 15 mesh. The rotating shaft 12 drives the movement of the gear 14 and the half gear 15. The cooperation between the gear 14 and the half gear 15 provides force transmission and controls the movement of the fixed plate 16. The end of the half gear 15 away from the gear 14 is fixedly connected to the fixed plate 16, providing a stable platform for the compression spring that needs to be cut. After cutting, the fixed plate 16 rotates open, and the cut compression spring falls onto the conveyor belt 24.

[0032] The clamping assembly includes springs 17, clamping plates 18, and fixing rods 19. Springs 17 are fixedly installed inside the fixing rings 7. Clamping plates 18 are fixedly installed on corresponding sides of the two springs 17. Fixing rods 19 are fixedly installed on corresponding sides of the two fixing rings 7. The clamping assembly also includes connecting rods 20, clamping rods 21, a second telescopic rod 22, and a cylinder 23. The cylinder 23, through its cooperation with the second telescopic rod 22, adjusts the position of the clamping rod 21, thereby changing the clamping force of the clamping rod 21. The two connecting rods 20... The top of the fixed ring 7 is rotatably connected to the top of the connecting rod 20. Both ends of the connecting rod 20 are rotatably connected to the clamping rod 21. One end of the clamping rod 21 is rotatably connected to the second telescopic rod 22. The end of the second telescopic rod 22 away from the clamping rod 21 is rotatably connected to the fixed rod 19. One end of the second telescopic rod 22 is rotatably connected to the cylinder 23. The end of the cylinder 23 away from the second telescopic rod 22 is rotatably connected to one side of the support frame 2. The workbench 1 is equipped with a conveyor belt 24, which can transport the cut compression springs.

[0033] The working process of this utility model:

[0034] Step 1: Before starting the worktable 1, the clamping assembly is installed and adjusted to the appropriate position. The cylinder 23 cooperates with the second telescopic rod 22 to adjust the clamping force of the clamping rod 21. According to the specifications of the compression spring to be cut, the cylinder 23 and the clamping assembly will be adjusted accordingly to ensure that the clamping plate 18 can firmly clamp the two ends of the compression spring. The rotation of the connecting rod 20 and the corresponding movement of the clamping rod 21 ensure that the compression spring remains stable during the cutting process.

[0035] Step 2: After the workbench 1 is started, the first telescopic rod 4 extends and retracts, thereby driving the cutting blade 6 to move longitudinally along the support frame 2. As the cutting blade 6 moves, the dust collection box 8 and dust collection pipe 9 in the cleaning component start to work, timely absorbing the debris generated during the cutting process. The cutting blade 6 is precisely positioned on the support frame 2, and the cutting area is controlled by the extension and retraction of the first telescopic rod 4 to ensure the accuracy and cleanliness of the cutting effect.

[0036] Step 3: After cutting, the fixed plate 16 rotates open through the cooperation of half gear 15 and gear 14. The cut compression spring will then fall onto the conveyor belt 24 for further processing. This process reduces manual operation, avoids misoperation caused by debris accumulation, and ensures the smoothness of the workflow.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
