1. 40*80 Elliptical Grooved Tube - **Specs and Structural Features** - **Dimensions**: This tube material has an elliptical cross-section with the major axis approximately 80mm and the minor axis approximately 40mm. The elliptical structure endows the tube with unique mechanical properties when subjected to pressure and bending forces.
Compared to round tubes, elliptical tubes offer better support in certain directions. - **Groove Features**: Grooves are typically distributed along the major or minor axis of the ellipse, or they may be circumferentially around the ellipse. The groove depth usually ranges from 3 to 7mm, with a width between 4 to 10mm.
The grooved design can be used for installing sealing materials, decorative strips, or securing other components. - **Key Production Process** - **Forming Process**: The production of elliptical grooved pipes typically involves a combination of cold bending and special mold pressing methods. Initially, the steel strip is subjected to preliminary cold bending to roughly form an elliptical shape, followed by further pressing through the designed molds.
To achieve the specified elliptical shape and groove dimensions. During this process, strict control over the steel strip material and thickness is essential; typically, steel strips with a thickness of 1.5 to 3mm are chosen, with materials such as carbon structural steel or low-alloy steel being common. - **Welding and Surface Treatment**: High-frequency welding is commonly used to ensure a firm connection at the tube edges. After welding, surface treatment such as galvanizing or painting is required to enhance the tube's corrosion resistance and aesthetic appeal. - **Application Fields** - **Construction**: In architectural structures like arched windows and door frames, and supporting structures for dome buildings, 40*80 elliptical groove tubes can provide excellent support due to their elliptical shape and mechanical properties.
The grooves can be used to install sealant strips or decorative lines, enhancing the functionality and aesthetics of the building. - **Automotive Industry**: In the framework structure of car bodies and some components, elliptical groove pipes can be used to manufacture parts with special shape requirements, such as components for the car's suspension system, certain parts of the exhaust system, etc.
Grooves can be used for installing shock-absorbing devices, thermal insulation materials, etc. - **In the Furniture Manufacturing Field**: They are used to create innovative furniture designs, such as oval table legs, chair armrests, etc. Grooves can also be used to install decorative strips or connect other furniture components, enhancing both the design and practicality of the furniture. 2. **20*40 Grooved Tube** - **Specification and Structural Features** - **Size Specification**: The cross-section is rectangular, with the long side being 40mm and the short side being 20mm. This is a relatively small tube material, suitable for applications with high space requirements or small structures. - **Groove Features**: The groove depth is generally 2-5mm, and the width is 3-8mm. Due to the smaller size of the tube, grooves are mainly used for installing small components, such as wire clamps, small decorative strips, etc., or for achieving simple connection functions. - **Production Process Highlights** - **Forming Process**: Cold bending forming process is used, where the appropriate steel strip (thickness usually between 1-2mm) is gradually bent into the required rectangular shape through rolling mills. For the 20*40 size, the parameters of the rolling mill are controlled to...
Ensure the stability of the shape and dimensions of the pipe material. The steel strip material can be carbon structural steel. - **Welding and Groove Production**: High-frequency welding is used for welding the edges of the pipe, and welding parameters should be adjusted according to the thin-walled characteristics of the steel strip to ensure weld quality. Groove production can be achieved using small mold stamping to ensure the dimensions and surface quality of the grooves.
And minimize the impact on the overall structure of the pipe as much as possible. - **Application Areas** - **Furniture and Interior Decoration Field**: In the manufacturing of small furniture (such as small shelves, flower stands, etc.), the 20*40 grooved pipe can be used as the frame material.
Grooves are designed for installing shelf supports, decorative strips, etc., enhancing the aesthetics and utility of furniture. In interior decoration, they can be used to make curtain rods, small decorative hangers, etc., with the grooves intended for installing hooks or pulleys. - **In the field of mechanical manufacturing**: They serve as part of the supporting structure or shell frame in some small mechanical devices. For example, in the shell frame of a small electronic device, grooves can be used to install fixed components for circuit boards or heat sinks. 3. **40*60 Groove Tube** - **Specification and Structural Features** - **Size Specification**: The cross-section is rectangular with a long side of 60mm and a short side of 40mm. This size of tube has certain structural stability and is suitable for various applications requiring certain load-bearing capacity. - **Groove Features**: The groove depth ranges from 3 to 7mm and the width is approximately 4 to 10mm. Grooves can be located on the outer, inner, or both sides of the tube. Outer grooves are primarily used for installing accessories such as decorative strips,
Accessories; If the inner recesses are used to conceal wiring, etc., they facilitate the placement of wires and cables. - **Key Production Processes** - **Molding Method**: Typically, cold bending molding technology is employed. The steel strip is passed through a series of designed rolling mills,
The steel strip is gradually bent into the required rectangular shape. During this process, the spacing, pressure of the rolling mill, and feeding speed of the steel strip must be strictly controlled according to the 40*60 size requirements.
Generally, steel strips with a thickness of 1.5 - 3mm are used, which can be carbon structural steel or low-alloy steel. - **Welding and Groove Production**: After the tube material is formed, the edges of the steel strip are welded together using high-frequency welding. Once welding is completed, grooves are produced by either die stamping or CNC machining.
The advantages of die stamping are high efficiency, suitable for mass production; CNC machining can achieve higher precision, used for situations requiring precise slot dimensions. - **Application Scenarios** - **Construction Field**: In the exterior decoration of buildings, it can be used as a framework to install materials such as aluminum panels and stone cladding. The slots are used to secure hangers, ensuring the firm installation of the cladding materials.
In interior decoration, these can be used to create large display rack frames. The grooves can accommodate dividers or display lighting to enhance the presentation. - **Industrial Equipment Field**: In the manufacturing of the outer shell frames for certain large industrial equipment, 40*60 groove tubes can provide stable structural support.
For example, in the frames of distribution and control cabinets, grooves are provided for installing side and door panel fasteners, facilitating equipment assembly and maintenance.
