Description

Technical Field

[0001] This utility model relates to the field of titanium alloy tube cutting technology, specifically a rapid cutting device based on titanium alloy tubes. Background Technology

[0002] Rapid cutting devices based on titanium alloy tubes typically employ high-power motors or hydraulic drive systems to provide sufficient power to the cutting blades, enabling them to overcome the high strength of the titanium alloy tubes and achieve rapid cutting. For example, some cutting devices use high-speed rotating cutting blades, which are driven by motors to cut the titanium alloy tubes at extremely high speeds.

[0003] Existing titanium alloy tube cutting devices rely on manual pressing of a handle to lower the cutting blade during cutting operations. However, manual pressing of the handle makes it difficult to flexibly control the cutting depth. Due to differences in the operator's hand strength, the force applied to the handle each time cannot be precisely consistent, resulting in fluctuations in cutting depth and affecting cutting quality. This is especially true for cutting titanium alloy tubes with strict thickness requirements, which can easily lead to defective products. Therefore, a rapid cutting device for titanium alloy tubes is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a rapid cutting device for titanium alloy tubes, which solves the problem that existing titanium alloy tube cutting devices rely on manual pressure of the handle to lower the cutting blade. However, due to differences in the operator's hand strength control, the pressure applied to the handle is not precise and consistent, resulting in fluctuations in cutting depth. This has a significant impact on cutting quality, especially when cutting titanium alloy tubes with strict thickness requirements, which can easily lead to the production of defective products.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figure 1-6 This utility model provides a technical solution:

[0030] A rapid cutting device based on titanium alloy tubes includes a support platform 1. A lead screw module 2 is fixedly connected to one side of the top of the support platform 1. A cutting assembly 3 is fixedly installed on the moving end of the lead screw module 2. A depth adjustment mechanism 4 is installed on the top of the cutting assembly 3. The cutting assembly 3 includes a base 31. A bracket 32 ​​is fixedly connected to the top of the base 31. A cutting blade 33 is rotatably connected to the bottom of the inner side of the bracket 32. A return spring 34 is fixedly connected between the back of the cutting blade 33 and the middle of the inner side of the bracket 32. The depth adjustment mechanism 4 includes an adjustment... The adjusting screw 41 is threadedly connected to the top of the inner side of the bracket 32. The front end of the adjusting screw 41 is fixedly connected to the pressure head 42. The outer side of the adjusting screw 41 is threadedly connected to the limit nut 43. One side of the limit nut 43 is threadedly connected to the fastening bolt 44. The front end of the limit nut 43 is rotatably connected to the feedback mechanism 45. The position of the pressure head 42 corresponds to the position of the top of the cutting blade 33. The rear end of the adjusting screw 41 is fixedly connected to the handwheel 46. The handwheel 46 and the adjusting screw 41 are located on the same central axis.

[0031] As a further implementation of this solution, the feedback mechanism 45 includes a limiting sleeve 451. The inner side of the limiting sleeve 451 has a sliding groove 452, a sliding groove 453, and a through hole 454. Multiple sliding grooves 452 are arranged in a circular pattern. The number of sliding grooves 453 is the same as the number of sliding grooves 452, and they are connected to each other. The angle between sliding grooves 453 and sliding grooves 452 is 90°. Sliding grooves 452 are located in the middle of the inner side of the limiting sleeve 451, and sliding grooves 453 are located above them. The through hole 454 is located above sliding grooves 453 and extends to the outer side of the limiting sleeve 451. A wedge block 452 is slidably connected to the inner side of sliding groove 452. 55. An inclined block 456 is slidably connected to the inner side of the sliding groove 453. An inclined block 455 extends to the front end of the limiting sleeve 451. An inclined block 455 and an inclined block 456 are slidably connected to each other, ensuring the effective transmission and conversion of force. A top rod 457 is fixedly connected to the top of the inclined block 456. The top rod 457 is slidably connected to the through hole 454. A return spring 458 is sleeved on the outer side of the top rod 457. The return spring 458 is located at the top of the inner side of the sliding groove 453. The bottom end of the return spring 458 is fixedly connected to the upper surface of the inclined block 456. This layout allows the return spring 458 to accurately push the inclined block 456 and the top rod 457 downward when releasing elastic potential energy, ensuring accurate reset of the inclined blocks 455 and 456 and ensuring the consistency of the cutting depth feedback each time.

[0032] As a further implementation of this solution, the limiting sleeve 451 and the limiting nut 43 are located on the same central axis. The limiting sleeve 451 is located behind the bracket 32, and the fastening bolt 44 extends into the interior of the limiting nut 43. By tightening the fastening bolt 44, the limiting nut 43 can be firmly fixed on the adjusting screw 41 to prevent the limiting nut 43 from loosening due to vibration and other factors during the cutting process, thereby ensuring the accuracy and stability of the cutting depth.

[0033] As a further implementation of this solution, a fixed seat 5 is fixedly connected to the other side of the top of the support platform 1. A drive motor 6 is fixedly connected to the back of the fixed seat 5 through a motor seat. A three-jaw chuck 7 is fixedly connected to the transmission shaft of the drive motor 6. The lead screw module 2 is parallel to the support platform 1. The cutting blade 33 is located on one side of the three-jaw chuck 7. The combination of the fixed seat 5, the drive motor 6 and the three-jaw chuck 7 provides stable fixing and rotational power for the titanium alloy tube, enabling the titanium alloy tube to rotate during the cutting process and achieve circumferential cutting in conjunction with the cutting blade 33.

[0034] Workflow: The titanium alloy tube is placed on the three-jaw chuck 7. The clamping action of the three-jaw chuck 7 firmly fixes the titanium alloy tube, providing stable workpiece support for the cutting operation. Using the drive mechanism of the lead screw module 2, the cutting component 3 installed on it moves along the slide rail. The base 31 in the cutting component 3 moves with the movement direction of the lead screw module 2, thereby driving the bracket 32, the cutting blade 33 and the depth adjustment mechanism 4 to move to the corresponding position of the titanium alloy tube to be cut, completing the initial positioning of the cutting position. When the cutting operation is performed, the handwheel 46 is turned to drive the adjusting lead screw 41 to move forward. At this time, the pressure head 42 pushes the cutting blade 33 in front to apply pressure, forcing the cutting blade 33 to move downward to cut the titanium alloy tube. After determining the maximum cutting depth of the cutting blade 33 through this operation, the limit nut 43 is turned to move it outside the adjusting lead screw 41. At the same time as the limit nut 43 rotates, it drives the feedback mechanism 45 to move synchronously until the front end of the feedback mechanism 45 abuts against the back of the bracket 32, thereby accurately determining the cutting depth.

[0035] After a cut is completed, the handwheel 46 is rotated in the opposite direction. At this time, the reset spring 34 takes effect and pulls the cutting blade 33 to rotate and reset, returning it to its initial position. At the same time, the adjusting screw 41 moves backward to reset. The reset spring 458 in the feedback mechanism 45 is fixedly connected to the upper surface of the second inclined block 456. The reset spring 458 releases elastic potential energy, pushing the second inclined block 456 and the top rod 457 to move down, so that the second inclined block 456 drives the first inclined block 455 to reset and return to the initial position, preparing for the next cutting operation.

[0036] Next, the lateral position of the cutting assembly 3 and the depth adjustment mechanism 4 is adjusted again using the lead screw module 2 to move them to the target position for the next cut. When the handwheel 46 is turned forward again to drive the adjusting lead screw 41 to move forward, the multiple inclined blocks 455 in the feedback mechanism 45 are squeezed by the bracket 32. The inclined blocks 455 push the inclined blocks 456 to drive the top rod 457 to move upward. By observing the protrusion of the top rod 457, the movement position of the adjusting lead screw 41 can be accurately fed back. When the top rod 457 moves to the corresponding maximum height, it indicates that the adjusting lead screw 41 has reached the preset cutting depth position. At this time, the cutting blade 33 reaches the same cutting depth as last time, and the cutting operation can continue to be completed to ensure that the cutting depth is consistent each time.

[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.
