Description

Technical Field

[0001] This invention relates to the field of cutting technology, specifically to a high-precision cutting equipment for producing luggage handles. Background Technology

[0002] As a lifting component in luggage assembly, the luggage pull rod requires multiple steps in its processing, including the cutting and processing of the luggage pull rod. Therefore, the quality of the cutting and processing equipment determines the overall subsequent production quality of the luggage. For example, the multi-functional luggage pull rod cutting machine with publication number CN220782391U includes a base. The upper surface of the base has a groove. A motor is fixedly connected to the inner wall of the base. A pull rod fixing device is provided inside the base. The pull rod fixing device includes a bidirectional threaded rod, which is fixedly connected to the output end of the motor. A fixing post is rotatably sleeved on the outer surface of the bidirectional threaded rod. The lower surface of the fixing post is fixedly connected to the inner wall of the base. It can fix pull rods of different diameters. Compared with traditional cutting machines, which can only fix pull rods of a single diameter through the groove for production, this device has a wider range of applications, is more convenient, and can adjust the position of the cutting blade. By adjusting the position of the cutting blade, cutting can be completed quickly and efficiently. For example, patent CN217889660U discloses a cutting device for producing luggage trolley rods, which includes a worktable. A cutting device is fixedly installed inside the worktable. The top of the cutting device extends to the top of the worktable. A sliding plate is slidably connected to the right side of the top of the worktable. A positioning frame is provided on the top of the sliding plate. The bottom of the positioning frame extends into the interior of the worktable. A movable plate is fitted on the bottom of the surface of the positioning frame. This device has the advantage of being able to position the luggage trolley rod during processing, solving the problem that traditional cutting devices lack a positioning structure and cannot position the luggage trolley rod. When cutting the luggage trolley rod, the luggage trolley rod is prone to shaking, resulting in low stability during cutting and reducing the production efficiency of luggage trolley rods. For example, the patent with publication number CN221538267U discloses a cutting device for producing luggage trolley rods, which includes a base. The bottom end of the base has a rectangular array of legs, and the top end of the base is fixed with a movable frame. The bottom end of the inner cavity of the movable frame is fixed with two electric telescopic rods, and the top end of the two electric telescopic rods is fixed with a first slider. The front end of the first slider is fixed with a cutting frame, and the cutting frame is equipped with a cutting tool and a driver. This structure can clamp trolley rods of various sizes. Traditional trolley rod clamping parts require manual adjustment. In contrast, this structure can achieve automatic adjustment, which greatly saves the time cost of workers, shortens the processing time, and improves the overall convenience. Most of the existing technologies mentioned above improve the overall structure. However, in the process of operation, the existing bag handle production cutting equipment mostly requires the user to place the workpiece manually. Under high-intensity cutting conditions, it is very easy to cause errors in the cutting accuracy, thus having certain limitations. At the same time, the waste generated during the cutting process of the overall cutting equipment can easily affect the user's accuracy judgment. Summary of the Invention

[0003] The purpose of this invention is to provide a high-precision cutting and sizing equipment for producing luggage handles, in order to solve the problems mentioned in the background art, where most workpieces are placed manually by the user. Under high-intensity cutting conditions, this can easily cause errors in the cutting accuracy, thus limiting its use. At the same time, the waste generated during the overall cutting process can affect the user's accuracy judgment.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-precision cutting and blanking device for producing luggage handles, comprising a preset base, a preset cutting assembly rotatably connected to the outer side of the preset base, and a docking fastener fixedly connected to the outer side of the shaft end of the preset cutting assembly; an abutting bearing member nested and docked on the inner side of the preset base, and a docking movable member nested and installed on the surface of the preset base, wherein the lower end positions of the docking movable member and the abutting bearing member correspond to each other; a first return spring fixedly connected to the outer side of the docking movable member, and the first return spring docking with the lower end of the preset base; and an adaptive auxiliary positioning mechanism provided at the upper end of the docking movable member, wherein the contacting workpiece is vertically locked by the adaptive auxiliary positioning mechanism.

[0005] Furthermore, the adaptive auxiliary positioning mechanism is provided with a vertical corrugated liquid bladder, which is connected to the outside of the docking movable part. The outer end of the vertical corrugated liquid bladder is connected to a supply hose, which runs along the outer side of the upper end of the docking movable part. The upper end of the docking movable part is connected to a horizontal corrugated liquid bladder, and the horizontal corrugated liquid bladder and the supply hose are interconnected.

[0006] Furthermore, the upper end of the docking movable part is connected to a horizontal limiting component, and the lower outer end of the horizontal limiting component is connected to the horizontal corrugated liquid bladder. The horizontal limiting components are symmetrically distributed about the center point of the preset base.

[0007] Furthermore, when the preset cutting component rotates, it drives the outer docking fixing component to rotate synchronously, and the docking fixing component applies pressure to the outer side of the contact bearing component synchronously. The contact bearing component drives the lower contact docking movable component to move down synchronously, and the docking movable component forms an elastic support structure along the lower end of the preset base through the first reset spring.

[0008] Furthermore, during the downward movement of the docking movable component, pressure is simultaneously applied to the contacting vertical corrugated liquid bladder, and the vertical corrugated liquid bladder supplies work to the interior of the horizontal corrugated liquid bladder through the supply hose. The horizontal corrugated liquid bladder expands laterally, pushing the outer horizontal limiting component to move outward.

[0009] Furthermore, a guiding pressure relief mechanism is provided on the outer side of the horizontal limiting component, which adaptively disperses the contacting cutting chips; the guiding pressure relief mechanism is provided with an anti-contact reserved part, which is nested and connected to the inner side of the left end of the horizontal limiting component, and an air storage cavity is opened on the inner side of the left end of the horizontal limiting component; a reserved through hole is opened on the left side of the horizontal limiting component, and the reserved through hole is connected to the air storage cavity.

[0010] Furthermore, the upper end of the horizontal limiting component is connected to a horizontal reserved supply pipe, and the horizontal reserved supply pipe is connected to the air storage cavity. The lower end of the horizontal limiting component is connected to a second return spring, and the second return spring is connected to the docking movable part.

[0011] Furthermore, during the downward movement of the docking movable part, the inner anti-collision reserved part is simultaneously subjected to force and moves. When the anti-collision reserved part moves to a position higher than the reserved through hole, the interior of the air storage cavity is in a closed air storage state. When the anti-collision reserved part moves to a position lower than the reserved through hole, the interior of the air storage cavity is in a state of connection with the outside.

[0012] Furthermore, when the abutting reserved part moves to a position higher than the reserved through hole, it pushes the gas stored inside the gas storage cavity to be supplied outward through the horizontal reserved supply pipe. The sealing part at the end of the horizontal reserved supply pipe is pressed open outward to supply gas.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This high-precision cutting equipment for luggage handles features an adaptive auxiliary positioning mechanism. This mechanism vertically locks the contacting workpiece. After placing the luggage handle workpiece to be cut on the outside of the preset base, the preset cutting component can be rotated for cutting. The docking fixing part that connects to the outside of the preset cutting component will rotate synchronously, applying pressure to the outside of the contact bearing part. This causes the contact bearing part to move the lower contacting movable part downwards synchronously. The movable part, with its elastic outer surface, vertically locks the contacting workpiece. This eliminates the need for the user to manually place the workpiece, preventing errors in cutting accuracy under high-intensity cutting conditions. Furthermore, as the supporting force of the docking movable part moves downward upon contact with the bearing part, its upper end will simultaneously apply pressure to the vertically corrugated liquid bladder in contact, causing the vertically corrugated liquid bladder to deform vertically and supply work through the supply hose to the interior of the horizontally corrugated liquid bladder. The horizontally corrugated liquid bladder will then expand horizontally, thereby pushing the outer horizontal limiting component to move outward along the upper end of the docking movable part. Thus, while the docking movable part locks the workpiece vertically, the horizontally limiting component in the outward state performs horizontal synchronous limiting treatment on the contacting workpiece, further ensuring the positioning range and support strength of the equipment, and preventing the support accuracy of the workpiece from being affected under high-intensity vibration cutting conditions. Furthermore, a guiding pressure relief mechanism is provided. This mechanism adaptively disperses the cutting waste during contact. As the mating movable part moves downward under force, the outer nested anti-collision pre-reserved part will be pre-stressed, thus moving vertically along the air storage cavity inside the mating movable part. When the anti-collision pre-reserved part moves higher than the pre-reserved through hole, the air storage cavity is in a closed air storage state. At this time, the anti-collision pre-reserved part will push the gas stored inside the air storage cavity to move outward through the horizontally placed pre-reserved supply pipe. The sealing part at the end of the horizontally placed pre-reserved supply pipe is pressed open to supply gas. Thus, the horizontally placed pre-reserved supply pipe achieves adaptive dispersion of stored cutting waste and auxiliary heat dissipation during adaptive positioning and cutting, improving the practicality of the device.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figure 1 - Figure 9 This invention provides the following technical solution: a high-precision cutting and blanking device for producing luggage handles. To address the problem that most workpieces are placed manually by the user, which easily leads to errors in cutting accuracy under high-intensity cutting conditions, thus limiting its usability, the invention discloses a device comprising: a preset base 1 with a preset cutting component 2 rotatably connected to its outer side; a docking fastener 3 fixedly connected to the outer side of the shaft end of the preset cutting component 2; a contact bearing component 4 nested and docked inside the preset base 1; a docking movable component 5 nested and installed on the surface of the preset base 1; the lower end of the docking movable component 5 corresponding to the lower end of the contact bearing component 4; a first return spring 6 fixedly connected to the outer side of the docking movable component 5; the first return spring 6 docking with the lower end of the preset base 1; and an adaptive auxiliary positioning mechanism at the upper end of the docking movable component 5 for vertical locking of the contacting workpiece.

[0018] The adaptive auxiliary positioning mechanism is equipped with a vertically placed corrugated liquid bladder 7, which is connected to the outside of the docking movable member 5. A supply hose 8 is inserted through the outer end of the vertically placed corrugated liquid bladder 7, and the supply hose 8 passes through the outer side of the upper end of the docking movable member 5. A horizontally placed corrugated liquid bladder 9 is connected to the upper end of the docking movable member 5, and the horizontally placed corrugated liquid bladder 9 and the supply hose 8 are interconnected. A horizontally placed limiting component 10 is inserted through the upper end of the docking movable member 5, and the lower outer end of the horizontally placed limiting component 10 is connected to the horizontally placed corrugated liquid bladder 9. The horizontally placed limiting components 10 are symmetrically distributed about the center point of the preset base 1. When the preset cutting component 2 rotates, it drives the outer docking fixing component 3 to rotate synchronously, and the docking fixing component 3 applies pressure to the outer side of the contact bearing component 4. The contact bearing component 4 drives the lower contact docking movable component 5 to move downward synchronously, and the docking movable component 5 forms an elastic support structure along the lower end of the preset base 1 through the first return spring 6. During the downward movement of the docking movable component 5, it applies pressure to the contacting vertical corrugated liquid bladder 7, and the vertical corrugated liquid bladder 7 supplies work to the interior of the horizontal corrugated liquid bladder 9 through the supply hose 8. The horizontal corrugated liquid bladder 9 expands laterally, pushing the outer horizontal limiting component 10 to move outward. After the bag handle workpiece to be processed is placed outside the preset base 1, the preset cutting component 2 can be rotated for cutting. The docking fixing part 3, which is connected to the outside of the preset cutting component 2, will rotate synchronously, applying pressure to the outside of the contact bearing part 4. This causes the contact bearing part 4 to move the lower contacting movable part 5 downwards synchronously. The movable part 5, with its elastic outer surface, vertically locks the contacting workpiece, preventing errors in cutting accuracy under high-intensity cutting conditions. As the movable part 5 contacts the contact bearing part 4 and moves downwards under supporting force, its upper end will... The vertically corrugated liquid bladder 7 is pressurized synchronously, causing it to deform vertically and supply fluid to the interior of the horizontally corrugated liquid bladder 9 through the supply hose 8. The horizontally corrugated liquid bladder 9 then expands laterally, thereby pushing the outer horizontal limiting component 10 to move outward along the upper end of the docking movable part 5. While the docking movable part 5 locks the workpiece vertically, the horizontally limiting component 10 in its outward movement synchronously limits the contacting workpiece laterally, further ensuring the positioning range and support strength of the equipment and preventing the support accuracy of the workpiece from being affected under high-intensity vibration cutting conditions.

[0019] Example 2: Based on Example 1, to address the issue that waste chips generated during the cutting process of the overall cutting equipment can easily affect the user's accuracy judgment, a guiding pressure relief mechanism is also disclosed, the specific structure of which is as follows: A guide pressure relief mechanism is provided on the outside of the horizontal limiting component 10, which adaptively disperses the contacting cutting chips. The pressure relief mechanism is provided with a retaining part 11, which is nested and connected to the inner left side of the horizontal limiting component 10. An air storage cavity 12 is provided on the inner left side of the horizontal limiting component 10, and a reserved through hole 13 is provided on the left side of the horizontal limiting component 10. The reserved through hole 13 is connected to the air storage cavity 12.

[0020] The upper end of the horizontal limiting component 10 is connected to a horizontal reserved supply pipe 14, which is connected to the air storage cavity 12. The lower end of the horizontal limiting component 10 is connected to a second return spring 15, which is connected to the docking movable part 5. During the downward movement of the docking movable part 5, the inner abutting reserved part 11 is simultaneously subjected to force. When the abutting reserved part 11 moves to a position higher than the reserved through hole 13, the interior of the air storage cavity 12 is in a closed air storage state. When the abutting reserved part 11 moves to a position lower than the reserved through hole 13, the interior of the air storage cavity 12 is in a state of connection with the outside. When the abutting reserved part 11 moves to a position higher than the reserved through hole 13, it pushes the gas stored inside the air storage cavity 12 to be supplied to the outside through the horizontal reserved supply pipe 14. The sealing element at the end of the horizontal reserved supply pipe 14 is pressed open to supply air. During the downward movement of the docking movable part 5, the abutting reserved part 11 nested on its outside will be pre-stressed, thus moving vertically along the air storage cavity 12 inside the docking movable part 5. When the abutting reserved part 11 moves higher than the reserved through hole 13, the inside of the air storage cavity 12 is in a closed air storage state. At this time, the abutting reserved part 11 will push the gas stored inside the air storage cavity 12 to move outward through the horizontal reserved supply pipe 14, and the sealing element at the end of the horizontal reserved supply pipe 14 is pressed open to supply air. Thus, the horizontal reserved supply pipe 14 realizes the adaptive dissipation of stored cutting waste and auxiliary heat dissipation during the adaptive positioning and cutting process.
