Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to a mobile polymer welding material extrusion welding equipment. Background Art

[0002] With the continuous progress of polymer material science, polymer materials such as polyethylene, polystyrene, polyvinyl chloride, nylon, etc. are widely used in various fields of social production and life. These materials have many advantages such as light weight, corrosion resistance, good insulation performance, etc., but in practical applications, they often need to be processed into products of various shapes and structures, or connected with other components, which puts forward the demand for polymer material welding technology.

[0003] Among the existing technologies, traditional welding methods such as arc welding and gas welding in metal welding are not suitable for polymer materials. Some polymer welding technologies developed later, such as vibration welding, hot plate welding, ultrasonic welding, etc., have met some welding needs to a certain extent, but they also have their own limitations. For example, vibration welding may cause internal stress in the product, affecting its dimensional stability and mechanical properties; hot plate welding has a slow welding speed and low efficiency; ultrasonic welding has certain restrictions on the thickness and shape of the welding material, and the welding effect is not good for some complex shapes or large products.

[0004] Extrusion molding is a commonly used method in polymer material processing. After the polymer material is heated and melted by an extruder, it is extruded through a mold of a specific shape under pressure to obtain a product with a certain shape and size. The development of extrusion molding technology has provided reference and ideas for polymer extrusion welding technology. Researchers have begun to explore whether the extrusion process can be combined with the welding process to achieve efficient and high-quality welding of polymer materials. Due to the joining characteristics of the material, the extrusion welding process is relied on in certain occasions. At present, the extrusion welding process relies on manual labor and is a high-physical labor operation project. The subjectivity of personnel directly affects the quality and efficiency of construction.

[0005] The above-mentioned prior art solutions have the following defects:

[0006] Unstable quality: In traditional extrusion welding, the heating methods of the base material to be welded and the welding rod are different, and it is difficult to ensure the uniformity of heating when the base material to be welded is heated by hot air, which can easily lead to inconsistent welding strength. At the same time, it is difficult to accurately control the pressure applied manually, and uneven pressure will prevent the molten welding rod from being in close contact with the base material, resulting in poor diffusion and entanglement between macromolecular chains, affecting the welding quality.

[0007] Low efficiency: Traditional extrusion welding relies on manual operation, such as manual feeding, moving the welding gun, etc., which is slow, and when welding large or complex structures, frequent arc starting and arc ending and position adjustment will further reduce efficiency. In addition, for thicker materials, the welding process requires many layers and takes a long time.

[0008] Poor appearance: The instability of manual operation can easily cause the weld to be uneven in width and height. The extruded molten material may shrink during the cooling process, resulting in an uneven weld surface, affecting the appearance and subsequent processing.

[0009] Material waste: welding rods usually need to be prepared in advance. If the size is not suitable or errors occur during welding, the welding rods may not be fully utilized, resulting in waste. In addition, the traditional process does not accurately control welding parameters, which may lead to welding defects due to improper parameters, requiring repair or re-welding, increasing material consumption.

[0010] High requirements for operators: Operators must have skilled operating skills and rich experience to better control welding speed, pressure, temperature and other parameters to ensure welding quality. At the same time, high temperature, strong light, harmful gases, etc. will be generated during the welding process. If the protection is not appropriate, it will cause harm to the operator's body.

[0011] Limited scope of application: Traditional extrusion welding is difficult to weld workpieces with complex shapes and narrow spaces. It has poor adaptability to welding materials of different materials and thickness combinations, and is not suitable for heat-sensitive polymer materials, which can easily cause material performance degradation.
