Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment lubrication technology, and in particular to a self-lubricating cutting device. Background Technology

[0002] Cutting devices are widely used in industrial production for cutting various materials. Their working principle typically involves a drive component that moves a cutting component to cut the target object. In traditional cutting devices, the cooperation between the slide rail and the slider is crucial for achieving precise positioning and smooth movement of the cutting component. To ensure smooth movement between the slide rail and the slider and reduce friction and wear, lubrication is usually required.

[0003] Currently, the most common lubrication methods for cutting devices on the market are manual periodic oiling and automatic lubrication systems. Among them, automatic lubrication systems have received widespread attention because they can provide a continuous and stable lubrication effect.

[0004] However, existing lubrication systems in cutting devices still have some problems. Traditional manual lubrication requires periodic manual operation, which is not only inefficient but also makes it difficult to ensure continuous and uniform lubrication. When lubrication is insufficient, the coefficient of friction between the slider and the guide rail fluctuates, leading to decreased cutting accuracy and accelerating wear on the guide rail and slider, while also generating metal debris that contaminates the processing environment. Existing automatic lubrication systems are often complex in structure, requiring additional power sources and control systems, increasing the cost and failure rate of the device. In addition, some lubrication systems are prone to causing lubricant waste and splashing during operation, resulting in resource waste and contamination of the working environment and processed products.

[0005] The purpose of this invention is to provide a self-lubricating cutting device that is simple in structure, provides continuous lubrication, and is easy to maintain.

[0006] To achieve the above objectives, this utility model provides a self-lubricating cutting device, comprising:

[0007] A fixed base on which a slide rail is installed;

[0025] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0026] This embodiment discloses a cutting device that can be used in the cutting process of various materials, such as in the processing of clothing fabrics.

[0027] like Figures 1 to 4 The cutting device includes a fixed base 1, a movable base 2, a cutting component 3, a drive component 4, an oil tank 5, and an oil suction strip 60.

[0028] The fixed base 1 serves as the basic support structure for the entire cutting device. It is made of metal and has sufficient rigidity and stability. A slide rail 10 is provided on the fixed base 1, which extends vertically.

[0029] The movable base 2 is mounted on the fixed base 1. A slider 20 is provided on one side of the movable base 2, and the slider 20 is slidably connected to the slide rail 10 on the fixed base 1.

[0030] The cutting component 3 is mounted on the movable base 2 and is used to perform cutting operations on the target object.

[0031] The drive assembly 4 is mounted on the fixed base 1 and connected to the movable base 2, and is used to drive the movable base 2 to reciprocate along the slide rail 10.

[0032] An oil tank 5 is mounted on a fixed base 1 and is used to hold lubricating oil. The oil tank 5 is made of stainless steel, providing excellent corrosion resistance and sealing performance. The volume of the oil tank 5 is designed according to actual usage requirements to ensure sufficient lubricating oil can be stored to meet the needs of long-term operation.

[0033] The oil-absorbing strip 60 is a flexible strip-shaped structure that absorbs liquid based on capillary action. One end of the oil-absorbing strip 60 is located in the oil groove 5, and the other end is located above or in contact with the slide rail 10. The oil-absorbing strip 60 absorbs the lubricating oil in the oil groove 5 through capillary action and delivers it to the surface of the slide rail 10, thereby achieving automatic lubrication of the slide rail 10.

[0034] In this embodiment, the cutting device utilizes an oil-absorbing strip 60, a flexible strip structure based on capillary action, to continuously deliver lubricating oil from the oil tank 5 to the surface of the slide rail 10, achieving automatic and continuous lubrication of the slide rail 10 without manual intervention. This effectively avoids fluctuations in the friction coefficient between the slider 20 and the slide rail 10 caused by untimely manual oiling, reducing wear on both the slide rail 10 and the slider 20, extending the equipment's service life, and minimizing metal debris generation, thus maintaining a clean processing environment. Furthermore, this continuous lubrication solution is simple in structure, low in cost, and easy to maintain, making it suitable for various cutting devices requiring lubrication of the slide rail 10.

[0035] On the other hand, the oil-absorbing strip 60 includes several cross-wound cotton threads, each thread and the threads forming tiny capillary channels that can effectively absorb and transfer lubricating oil. The length of the oil-absorbing strip 60 is determined according to the distance from the oil groove 5 to the slide rail 10, ensuring that the lubricating oil can be smoothly delivered to the surface of the slide rail 10.

[0036] On the other hand, a rigid protective tube 61 can be fitted onto the oil-absorbing strip 60. The protective tube 61 prevents the oil-absorbing strip 60 from bending and deforming due to its own weight, causing lubricating oil to drip from the middle. It also protects the oil-absorbing strip 60 from external environmental influences, extending its service life. The protective tube 61 can be made of copper, plastic, or silicone tubing. Copper tubing has good thermal conductivity and corrosion resistance, enabling stable operation in various environments. The inner diameter of the protective tube 61 is slightly larger than the outer diameter of the oil-absorbing strip 60, ensuring that the oil-absorbing strip 60 can freely expand and contract within the protective tube 61 without affecting its oil-absorbing function.

[0037] On the other hand, the oil tank 5 is filled with oil-absorbing blocks 7 (such as...). Figure 2 The oil-absorbing block 7 dynamically stores or releases lubricating oil based on the capillary effect of porous media, and the oil-absorbing strip 60 is connected to the oil-absorbing block 7. Specifically, the oil-absorbing block 7 is made of a sponge block with a large number of micropores, which can effectively store lubricating oil and release it when needed. The porosity and oil absorption capacity of the sponge block are optimized to ensure a stable supply of lubricating oil, meeting the needs of the cutting device for long-term operation. In addition, the oil-absorbing block 7 effectively prevents the vibration waves generated during the operation of the cutting device from shaking the lubricating oil out of the oil tank 5.

[0038] On the other hand, the cutting device in this embodiment also includes a rigid oil guide strip 8 (such as...). Figure 4 The drive assembly 4 includes a lead screw 40 and a drive motor 41 that is connected to the lead screw 40 for transmission. A through hole 50 is provided at the bottom of the oil trough 5. The first end of the oil guide strip 8 passes through the through hole 50 and remains in the oil trough 5, while the second end of the oil guide strip 8 abuts against the outer wall of the lead screw 40. The first end of the oil guide strip 8 is higher than the second end, so that the lubricating oil in the oil trough 5 flows along the outer peripheral wall of the oil guide strip 8 onto the lead screw 40. The oil guide strip 8 is made of metal with a smooth surface, which facilitates the flow of lubricating oil. The tilt angle of the oil guide strip 8 is optimized to ensure that the lubricating oil can flow smoothly onto the lead screw 40, achieving automatic lubrication of the lead screw 40.

[0039] On the other hand, the cutting assembly 3 includes a cutter head 30, a drill bit 31, and a rotary motor 32 arranged side-by-side on the fixed base 1. The rotary motor 32 is connected to the cutter head 30 and the drill bit 31 to drive them to rotate. A lifter 33 connected to the drill bit 31 is also provided on the fixed base 1. The cutter head 30 is suitable for cutting the target material, and the drill bit 31 is suitable for drilling the target material. The rotary motor 32 is a high-speed motor, capable of providing sufficient speed and torque to meet the needs of cutting and drilling. The lifter 33 uses a pneumatic or hydraulic mechanism to precisely control the lifting position of the drill bit 31, ensuring the coordinated use of the drill bit 31 and the cutter head 30.

[0040] In summary, this utility model discloses a cutting device. In actual use, lubricating oil is first added to the oil tank 5. The lubricating oil is drawn in by the capillary action of the oil suction strip 60 and transported to the surface of the slide rail 10, forming a thin oil film. Simultaneously, the lubricating oil flows through the oil guide strip 8 to the lead screw 40, lubricating it. When the drive motor 41 starts, the lead screw 40 rotates, driving the movable base 2 to reciprocate along the slide rail 10. The cutting component 3 moves along with the movable base 2 to cut the target object. Throughout this process, the slide rail 10 and the lead screw 40 maintain good lubrication, reducing friction and wear, and extending the service life of the equipment.

[0041] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
