Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a cutting machine with a convenient cutting blade head replacement. Background Technology

[0002] In related processing fields, cutting machines are core equipment, and their cutting heads need to be frequently changed according to processing requirements to adapt to different cutting sizes and shapes.

[0003] Traditional cutting machines typically use bolts or single-clamp locking mechanisms to fix the cutter head and cutter holder. Replacement requires specialized tools such as wrenches and screwdrivers to gradually disassemble the fasteners, making the process cumbersome and time-consuming. Especially in mass production scenarios, each cutter head replacement results in significant downtime, severely impacting effective production time and hindering overall processing efficiency, making it difficult to meet the demands of modern production lines for rapid changeover. Although some existing technologies attempt to optimize the cutter head replacement structure by adopting spring clips or single-point quick-release designs, there are still obvious defects: after long-term use, the spring clips are prone to elastic decay due to metal fatigue, which can lead to loosening of the cutter head locking. This can easily cause displacement deviations during the cutting process, affecting processing accuracy. During high-speed cutting, the vibration amplitude of the cutter head increases, which not only shortens the service life of the cutter head but may also cause safety hazards.

[0004] To address the aforementioned issues, we propose a cutting machine with a convenient cutting head replacement mechanism. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cutting machine that allows for easy replacement of the cutting blade.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cutting machine with a convenient cutting head replacement includes a punching table and a quick-change assembly; the quick-change assembly includes a fixed cylinder, a sliding column slidably installed inside the fixed cylinder, a retaining ball fixedly installed on the side wall of the sliding column, an L-shaped guide groove opened on the inner wall of the fixed cylinder, a concave hole opened at the lower end of the L-shaped guide groove, the retaining ball slidably engaging inside the L-shaped guide groove, a tension spring fixedly connected to the inner end of the sliding column, a rotating ring rotatably installed on the outer wall of the sliding column, connecting folding rods symmetrically fixedly installed on both sides of the rotating ring, and a locking block fixedly installed at the end of the connecting folding rod.

[0007] Furthermore, a torque handle is fixedly installed on the outer end of the sliding column.

[0008] Furthermore, a bracket is fixedly installed on the upper side of the punching platform, a controller is fixedly installed on the outer wall of the bracket, a cylinder is fixedly installed at the bottom of the bracket, and a structural mounting plate is fixedly installed on the lower side of the cylinder output end.

[0009] Furthermore, a mounting groove is fixedly installed on the lower side of the structural mounting plate base, a cutter head is provided on the lower side of the mounting groove, a cutter holder is fixedly connected to the upper side of the cutter head, and the cutter holder is locked and installed inside the mounting groove.

[0010] Furthermore, protective sleeves are symmetrically fixedly installed on the side wall of the mounting groove, and locking holes are symmetrically opened on the tool holder.

[0011] Furthermore, the fixing cylinder is fixedly installed on the side wall of the mounting groove, the connecting folding rod is slidably inserted into the inner side of the protective cylinder, the locking block is slidably inserted into the inner side of the locking hole, and the inner end of the tension spring is fixedly connected to the outer wall of the mounting groove.

[0012] Furthermore, the punching table is provided with a cutting groove.

[0013] Furthermore, guide telescopic rods are symmetrically connected between the upper side of the structural mounting plate and the bottom of the bracket.

[0014] Compared with related technologies, the cutting machine with convenient cutting head replacement proposed in this utility model has the following beneficial effects: This invention discloses a cutting machine with a convenient cutting head replacement mechanism. Through a quick-change component, when disassembling and replacing the cutting head, simply twist the sliding column to rotate the locking ball on the side of the sliding column to the bend of the L-shaped guide groove.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Reference Figures 1-7 A cutting machine with a convenient cutting head replacement: including a punching table 1 and a quick-change assembly 9; the quick-change assembly 9 includes a fixed cylinder 91, a sliding column 92 slidably installed on the inner side of the fixed cylinder 91, a retaining ball 97 fixedly installed on the side wall of the sliding column 92, an L-shaped guide groove 99 opened on the inner wall of the fixed cylinder 91, a concave hole 910 opened at the lower end of the L-shaped guide groove 99, the retaining ball 97 slidably engages with the inner side of the L-shaped guide groove 99, a tension spring 98 fixedly connected to the inner end of the sliding column 92, a rotating ring 93 rotatably installed on the outer wall of the sliding column 92, connecting folding rods 94 symmetrically fixedly installed on both sides of the rotating ring 93, and a locking block 95 fixedly installed at the end of the connecting folding rod 94.

[0019] In this configuration, a handle 96 is fixedly installed on the outer end of the sliding column 92.

[0020] With the above-described configuration, the handle 96 is designed to facilitate turning the slide 92, making it easier to manually change the cutter head 8 on a daily basis.

[0021] In this method, a bracket 2 is fixedly installed on the upper side of the punching table 1, a controller 3 is fixedly installed on the outer wall of the bracket 2, a cylinder 4 is fixedly installed at the bottom of the bracket 2, a structural mounting plate 5 is fixedly installed on the lower side of the output end of the cylinder 4, a mounting groove 7 is fixedly installed on the lower side of the structural mounting plate 5, a cutter head 8 is provided on the lower side of the mounting groove 7, a cutter holder 81 is fixedly connected to the upper side of the cutter head 8, the cutter holder 81 is locked and installed inside the mounting groove 7, and guide telescopic rods 6 are symmetrically connected between the upper side of the structural mounting plate 5 and the bottom of the bracket 2.

[0022] With the above-mentioned setup, the starting cylinder 4 can drive the bottom-mounted cutter head 8 to punch downwards. When the cutter head 8 punches into the inner side of the cutter groove 10, the material cutting is completed. The guide telescopic rod 6 makes the structural mounting plate base 5 move up and down more stably under the drive of the cylinder 4, thus improving the stability during punching.

[0023] In this method, protective sleeves 71 are symmetrically fixedly installed on the side wall of the mounting groove 7, and locking holes 82 are symmetrically opened on the tool holder 81.

[0024] With the above-mentioned arrangement, the sleeve 71 provides a sliding guide for the connecting folding rod 94, making the locking block 95 at the inner end of the connecting folding rod 94 more stable and less prone to shaking.

[0025] In this method, the fixed cylinder 91 is fixedly installed on the side wall of the mounting groove 7, the connecting folding rod 94 is slidably inserted into the inner side of the protective cylinder 71, the locking block 95 is slidably inserted into the inner side of the locking hole 82, and the inner end of the tension spring 98 is fixedly connected to the outer wall of the mounting groove 7.

[0026] With the above-mentioned setup, under normal locking conditions, the pull force provided by the spring 98 causes the sliding column 92 to drive the locking block 95 at the end of the connecting lever 94 to be stably locked inside the locking hole of the tool holder 81. At the same time, the concave hole 910 at the end of the L-shaped guide groove 99 engages with the locking ball 97, preventing the sliding column 92 from sliding outward under complex working conditions, further improving the locking stability.

[0027] In this method, the punching table 1 is provided with a knife groove 10.

[0028] The working principle of the cutting machine with convenient cutting head replacement provided by this utility model is as follows: During normal cutting operation, the operator activates the device via controller 3 on the outer wall of bracket 2. Upon receiving the command, cylinder 4 pushes the structural mounting plate 5 connected to the output end downward. During this process, the guide telescopic rods 6 symmetrically connected between the upper side of the structural mounting plate 5 and the bottom of bracket 2 provide guidance and stability, preventing the structural mounting plate 5 from shifting during movement. As the structural mounting plate 5 moves downward, the cutter head 8 locked in its lower mounting groove 7 moves downward synchronously until the cutter head 8 enters the cutter groove 10 opened on the punching table 1, completing the cutting operation of the flexible material placed on the punching table 1. At this time, the quick-change component 9 is in the locked state. The tension spring 98 inside the fixed cylinder 91 generates a pull force, which pulls the slide column 92 to move inward. Then, through the rotating ring 93, it drives the connecting folding rods 94 on both sides to slide inside the protective cylinder 71, so that the locking block 95 at the end of the connecting folding rod 94 is stably inserted into the locking hole 82 of the cutter holder 81. At the same time, the locking ball 97 on the side wall of the slide column 92 is locked in the concave hole 910 at the lower end of the L-shaped guide groove 99, thus doubly ensuring the stability of the cutter head 8 during the cutting process. When it is necessary to replace the cutter head 8, the operator holds the handle 96 on the outer end of the slide column 92 and turns it, causing the slide column 92 to rotate. This causes the retaining ball 97 on the side wall of the slide column 92 to disengage from the concave hole 910 and rotate to the bend of the L-shaped guide groove 99. Then, the operator pulls the handle 96 outward, and the slide column 92 slides outward in the fixed cylinder 91 and stretches the tension spring 98. The slide column 92 drives the connecting lever 94 to move outward synchronously through the rotating ring 93. The locking block 95 at the end of the connecting lever 94 gradually exits from the locking hole 82 of the cutter holder 81, releasing the locking restriction on the cutter holder 81. At this point, the operator can remove the tool holder 81 from the mounting slot 7, replace it with a tool holder 81 with a new tool head 8, and place it back into the mounting slot 7. Loosen the handle 96, and the pull force of the spring 98 will cause the slide column 92 to reset. The locking block 95 will be inserted into the locking hole 82 of the new tool holder 81 again. Turn the handle 96 to make the locking ball 97 re-engage into the recessed hole 910, thus completing the replacement of the tool head 8. The whole process does not require special tools, making the operation convenient and significantly reducing downtime.
