Description

Technical Field

[0001] The utility model relates to the field of civil engineering construction equipment, in particular to a friction welding machine. Background Art

[0002] Geogrid is a major geosynthetics material. Compared with other geosynthetics, it has unique properties and functions. It is often used as reinforcement for reinforced soil structures or reinforcement for composite materials. Polyester fiber warp knitted geogrid uses high-strength polyester fiber as raw material. The single belt of the geogrid is woven or sandwiched at a certain interval in the longitudinal and transverse directions. The intersection is welded by special enhanced bonding fusion welding technology to form a warp knitted directional structure. The warp and weft yarns in the fabric are not bent to each other. High-strength polyester fiber warp knitted geogrid has high tensile strength, low elongation, high tear strength, small longitudinal and transverse strength difference, UV aging resistance, wear resistance, corrosion resistance, light weight, strong interlocking force with soil or gravel, and has a significant effect on enhancing the shear resistance of soil and reinforcing and improving the integrity and load capacity of soil.

[0003] The traditional geogrid welding method requires a lot of energy to heat the grid bars to the melting point during the welding process. Since the temperature control and pressure application during the welding process are difficult to accurately control, it is easy to cause loose welding and uneven welds. In addition, the welding equipment often produces high-decibel noise during operation, which not only threatens the health of the operators, but also may affect the peace and comfort of the working environment. Therefore, there are problems such as high energy consumption, high noise, and unstable welding quality, which affect the quality and use effect of the geogrid. Therefore, the utility model proposes a friction welding machine. Utility Model Content

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] The following is an explanation of the preferred embodiments of the device of the utility model.

[0019] See also Figure 1-2 As shown, the friction welding machine includes a frame 1, a high-strength beam 2 is provided on the top of the frame 1, a plurality of pressure heads 3 are linearly arranged on the high-strength beam 2, the bottoms of the plurality of pressure heads 3 are fixedly connected with an upper friction head tooth plate 4, a high-frequency permanent magnet vibration head 7 is fixedly installed at the bottom of the frame 1, a permanent magnet block 9 is embedded in the high-frequency permanent magnet vibration head 7, and a permanent magnet motor 10 is fixedly connected below the high-frequency permanent magnet vibration head 7, a vibration support plate 8 is provided on the top of the high-frequency permanent magnet vibration head 7, a vibration slider 6 is provided below the vibration support plate 8 and on the side of the high-frequency permanent magnet vibration head 7, and a lower friction head tooth plate 5 corresponding to the upper friction head tooth plate 4 is provided on the top of the vibration support plate 8.

[0020] Among them, the lower surface of the upper friction head tooth plate 4 and the upper surface of the lower friction head tooth plate 5 are set to be tooth-shaped, and the high-frequency permanent magnet vibration head 7 is directly arranged below the vibration support plate 8 as the main vibration source, which can ensure that the vibration energy is directly and efficiently transmitted to the support plate and the workpiece above, reducing the energy loss in the transmission process, and the high-frequency permanent magnet vibration head 7 drives the lower friction head tooth plate 5 to vibrate at high frequency, forming rapid friction with the upper friction head tooth plate 4, thereby quickly completing the welding process and greatly improving the welding efficiency. Compared with traditional welding methods, high-frequency friction has lower energy consumption and reduces noise generation, which is beneficial to improving the working environment and improving the comfort of operators. The peeling force after welding is high and the loss is small, which contributes to improving the quality of geogrids used in roadbed construction. By accurately controlling the working parameters of the pressure head 3 and the high-frequency permanent magnet vibration head 7, accurate control of the welding process can be achieved to ensure the stability and consistency of the welding quality.

[0021] The single lower friction head tooth plate 5 of the equipment can perform single-point adjustment vibration friction butt welding on the intersection of the geogrid strips. A single or multiple groups of high-frequency permanent magnet vibration heads 7 can drive the vibration support plate 8 to weld geogrid meshes with a width of 1 to 8 meters. 1 to 6 horizontal strips can be welded at one time. It is suitable for: PET geogrid, PP geogrid, fiber-plastic geogrid, steel-plastic geogrid and other welded geogrid meshes.

[0022] When in use, first, place the geogrid strips to be welded on the vibrating support plate 8, ensuring that the intersection of the geogrid strips is located above the lower friction head tooth plate 5. Then, drive the pressure head 3 and the high-frequency permanent magnetic vibration head 7 to press the upper friction head tooth plate 4 down to contact the lower friction head tooth plate 5, and start high-frequency vibration. Under the action of vibration, rapid friction is generated between the upper friction head tooth plate 4 and the lower friction head tooth plate 5, so that the material at the intersection of the geogrid strips melts and is tightly combined.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
