Description

Technical Field

[0001] This utility model relates to the technical field of machine tool baffle equipment, specifically a corrosion-resistant flexible baffle with a hinge structure. Background Technology

[0002] In machine tool processing, flexible baffles are one of the core protective components, and they need to simultaneously meet two major requirements: "flexible bending to adapt to machine tool movement" and "stable blocking of cutting media". The mainstream manufacturing scheme for existing flexible baffles is to use multiple interlocking aluminum strips as a skeleton, and connect the aluminum strips sequentially by connecting strips (mostly made of rubber or nitrile rubber) to form a flexible integral baffle structure.

[0003] However, this solution has obvious flaws in practical applications, the specific problems of which are as follows: 1. Poor corrosion resistance and short service life: The cutting fluid (containing mineral oil, emulsifier, rust inhibitor, etc.) generated during machine tool processing will continuously corrode the rubber and nitrile rubber connecting strips, causing the strips to gradually age, crack, and lose their adhesion and buffering capacity; eventually leading to the failure of the connection between aluminum strips, resulting in problems such as aluminum strip breakage and baffle disintegration. The service life is usually only 1-2 months, requiring frequent replacement and increasing the company's operation and maintenance costs.

[0004] 2. Insufficient fastening performance and limited protection: The original fastening aluminum strips mostly use straight edges or simple snap-fit ​​designs at the meshing points, which have poor guidance and low sensitivity during fastening, and the contact gap is large after meshing; cutting fluid is easy to leak from the meshing gap, contaminating the machine tool guide rails and electrical components, increasing the risk of equipment failure.

[0005] Based on the shortcomings of the existing technology, there is an urgent need for a flexible baffle solution that can improve connection stability, enhance corrosion resistance, and optimize fastening performance. Utility Model Content

[0006] The purpose of this utility model is to provide a corrosion-resistant flexible baffle with a hinge structure and a double fixing design. It retains the flexible bending ability of the rubber strip and enhances the connection strength between the aluminum strips through rigid connection, so as to avoid the aluminum strips shaking and breaking when the machine tool moves at high speed. This ensures that the baffle can still stably block the cutting medium under dynamic working conditions, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A corrosion-resistant flexible baffle with a hinged structure includes: The main structure is composed of several groups of aluminum strips, with adjacent aluminum strips meshing together. The edge of the aluminum strip is provided with a meshing surface. Adjacent aluminum strips mesh together through the meshing surface, and the meshing surface is a rounded transition meshing surface. When adjacent aluminum strips mesh, the guiding effect of the rounded meshing surface improves the fastening sensitivity and increases the meshing contact area while reducing the gap.

[0008] Preferably, a groove for adhesive strips is reserved between adjacent aluminum strips, and an oil-resistant nitrile connecting adhesive strip is embedded in the groove to achieve a flexible connection between the aluminum strips and ensure that the baffle can be bent normally to adapt to the movement of the machine tool.

[0009] Preferably, both ends of the aluminum strip are symmetrically cut with planar connecting sections, so that the end face of the aluminum strip forms a convex structure.

[0010] Preferably, a connecting gasket is installed in the planar connection section between adjacent aluminum strips. The connecting gasket is an integrally formed structure made of 304 stainless steel to prevent the gasket from rusting and failing due to corrosion by cutting fluid.

[0011] Preferably, the connecting gasket and the adjacent aluminum strip have compatible planar connecting sections, and the connecting gasket is fixed to the planar connecting section by self-tapping screws.

[0012] Preferably, the self-tapping screw is inserted from the outside of one of the adjacent aluminum strips, and passes sequentially through the planar connecting section of the aluminum strip, the connecting washer, and the planar connecting section of the other aluminum strip, until the screw head is tightly attached to the surface of the aluminum strip and tightened.

[0013] Preferably, the self-tapping screw is a galvanized carbon steel screw or a stainless steel screw with a Phillips head pan head design, which facilitates quick assembly and disassembly with a screwdriver.

[0014] Compared with the prior art, the beneficial effects of this utility model are: Employing a dual-connection structure, the rigid connection (waistet + self-tapping screw) completely distributes the stress on the connecting strip. Even if the strip ages due to long-term corrosion, the aluminum strip remains fixed by the rigid connection, preventing breakage. The guiding nature of the arc-shaped meshing structure makes the aluminum strip engagement more sensitive, and the increased meshing contact area reduces cutting fluid leakage, effectively protecting the machine tool guideways and electrical components. Retaining the original flexible design of the connecting strip, it can directly replace the existing machine tool's flexible baffle (without modifying the machine tool mounting structure); simultaneously, the added washer and screw cost is extremely low.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figure 1-6 This utility model provides a technical solution: A corrosion-resistant flexible baffle with a hinged structure includes: The main structure is composed of several groups of aluminum strips 3, with adjacent aluminum strips 3 meshing together. The edge of the aluminum strip 3 is provided with a meshing surface 6. Adjacent aluminum strips 3 are meshed together through the meshing surface 6. The meshing surface 6 is a rounded transition meshing surface 6. When adjacent aluminum strips 3 are meshed, the guiding effect of the rounded meshing surface 6 improves the fastening sensitivity and increases the meshing contact area while reducing the gap.

[0019] The original snap-fit ​​aluminum strip 3 is processed a second time using the above technical solution, optimizing two key structural aspects: 1. End connection section cutting: Cut flat connection sections 5 at both ends along the length of aluminum strip 3 (the cut surface must be polished smooth to avoid burrs scratching the connecting strip 4 or the operator). This flat section is used for subsequent installation of connecting gasket 1 and self-tapping screws. 2. Optimization of meshing structure: The original straight edge meshing part of aluminum strip 3 is processed into a rounded transition meshing surface 6. During meshing, the guiding effect of the rounded surface improves the meshing sensitivity, while increasing the meshing contact area and reducing the gap.

[0020] In summary, upgrading the straight edge meshing surface 6 of aluminum strip 3 to a rounded transition shape improves the meshing sensitivity through the guiding effect of the rounded arc (quick meshing without repeated alignment), while increasing the meshing contact area and reducing the meshing gap, effectively preventing cutting fluid leakage, avoiding contamination of machine tool guideways and electrical components, and reducing the risk of equipment failure.

[0021] For a preferred implementation, please refer to Figure 1-3 : A groove for adhesive strips is reserved between adjacent aluminum strips 3. An oil-resistant nitrile material connecting adhesive strip 4 is embedded in the groove to achieve a flexible connection between the aluminum strips 3, ensuring that the baffle can be bent normally to adapt to the movement of the machine tool.

[0022] The oil-resistant nitrile rubber connecting strip 4 replaces ordinary rubber / nitrile rubber, which improves its resistance to cutting fluid (including mineral oil and emulsifiers) corrosion and can withstand long-term immersion without aging and cracking. Combined with 304 stainless steel connecting gasket 1 and galvanized carbon steel / stainless steel self-tapping screws 2, it completely solves the connection failure problem caused by corrosion of traditional rubber strips and rust of gaskets, extends the overall service life of the baffle, reduces the frequency of replacement, and significantly reduces the company's operation and maintenance costs.

[0023] For a preferred implementation, please refer to Figure 1-6 : Both ends of the aluminum strip 3 are symmetrically cut with flat connecting sections 5, forming a convex structure on the end face of the aluminum strip 3. A connecting washer 1 is installed within the flat connecting section 5 between adjacent aluminum strips 3. The connecting washer 1 is a one-piece molded structure made of 304 stainless steel to prevent corrosion from cutting fluid that could cause the washer to rust and fail. The connecting washer 1 and the flat connecting section 5 of the adjacent aluminum strip 3 are sized to fit each other, and the connecting washer 1 is fixed to the flat connecting section 5 by a self-tapping screw 2. The self-tapping screw 2 is inserted from the outside of one of the adjacent aluminum strips 3, passing sequentially through the flat connecting section 5 of the aluminum strip 3, the connecting washer 1, and the flat connecting section 5 of the other aluminum strip 3, until the screw head is flush with the surface of the aluminum strip 3 and tightened.

[0024] The two adjacent improved arc-shaped interlocking aluminum strips 3 are fixed using a dual method of "flexible connection + rigid auxiliary connection", which takes into account both the need for flexible bending and connection stability. First layer: Flexible base connection: Retain the original connection method of the connecting strip 4 - embed the oil-resistant nitrile rubber strip (or reinforced rubber strip) into the reserved rubber strip groove of the two aluminum strips 3 to achieve a flexible connection between the aluminum strips 3, ensuring that the baffle can be bent normally to adapt to the movement of the machine tool.

[0025] Second layer: Rigid auxiliary connection: Install a stainless steel connecting washer 1 (the size is perfectly matched with the flat connecting section 5, and the material is 304 stainless steel to resist cutting fluid corrosion) at the flat connecting section 5 at the ends of the two aluminum strips 3; then use a self-tapping screw to pass through the outside of one of the aluminum strips 3, through the flat connecting section 5 of the aluminum strip 3, the stainless steel connecting washer 1, and the flat connecting section 5 of the other aluminum strip 3 in sequence, until the screw head is close to the surface of the aluminum strip 3 and tightened.

[0026] In summary, the dual fixing design of "flexible connection (oil-resistant rubber strip) + rigid auxiliary connection (waist plate + screw)" not only retains the flexible bending ability of the rubber strip, but also enhances the connection strength between the aluminum strips 3 through rigid connection, so as to prevent the aluminum strips 3 from shaking and breaking when the machine tool moves at high speed, and ensure that the baffle can still stably block the cutting medium under dynamic working conditions.

[0027] For a preferred implementation, please refer to Figure 1-6 : Self-tapping screw 2 is a galvanized carbon steel screw or stainless steel screw with a cross-shaped pan head design, which facilitates quick assembly and disassembly with a screwdriver.

[0028] The combination of the flat connecting section 5 at the end of the aluminum strip 3 and the cross-slot pan head self-tapping screw 2 shortens the disassembly and assembly time of a single set of aluminum strip 3 (no special tools are required, only a screwdriver is needed); the stainless steel washer is precisely matched with the size of the flat section of the aluminum strip 3, and no alignment adjustment is required during installation, further reducing maintenance difficulty and improving installation and maintenance efficiency, which is especially suitable for the rapid replacement needs in scenarios where machine tools are frequently overhauled.

[0029] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
