Description
Technical Field
The invention relates to the technical field of welding processing, in particular to a welding device for metal furniture processing.
Background
Metal furniture is widely used in home, office and public places due to its sturdy and durable, modern and attractive properties. The furniture generally takes metal pipes, plates and the like as main structures, and the metal upright posts, the cross beams and other parts are welded and connected to form an integral frame so as to achieve necessary structural strength and stability. The welding process is a vital link in the production of metal furniture, the welding quality directly affects the strength, durability and aesthetic appearance of the finished product, and especially in mass production, the welding efficiency and accuracy become key problems of concern of manufacturers.
Currently, the welding of metal furniture mainly relies on semi-automatic or automated welding devices. These devices are generally suitable for smaller scale production, mainly for welding of single or small batches of metal components. For example, patent CN118060683a discloses a metal furniture upright welding apparatus, in which a plurality of brackets are used to fix a connecting member, and then a welding device driven by a servo motor is used to perform synchronous welding. The welding efficiency of a single upright post can be improved to a certain extent by the equipment, but the design and the prior art of the equipment still have obvious defects in practical application, and the equipment is particularly characterized in the following aspects:
The existing equipment adopts a single-piece operation mode, namely only one upright post can be welded at a time, and the workpiece is manually unloaded and the next workpiece is reinstalled after the welding is finished. The process has strong intermittence of production, is difficult to realize continuous production, and is not suitable for the requirements of high-efficiency and mass production. Particularly, on modern production lines, the metal furniture has large demand, and welding equipment is required to have continuous and automatic welding capability so as to meet the requirement of efficient production.
The operation flow is complex, time and labor are consumed, and operators need to manually take out welded workpieces after the welding of the existing equipment is finished, and then replace new components to be welded. The process is high in repeatability, time-consuming and labor-consuming, not only increases the complexity of manual operation and the labor-hour cost, but also causes low overall production efficiency. The limitation of the operation flow of the equipment is obvious especially in high-frequency production scenes, and is not suitable for the requirement of large-scale production.
The welding positioning accuracy is insufficient, and the quality of finished products is affected, namely, when the existing welding equipment is used for fixing workpieces, a simple mechanical clamping mode is generally adopted, but the positioning accuracy of the fixing mode is lower. The metal upright post and the connecting piece are easy to deviate when being welded, so that welding is uneven or angles are inaccurate, and further the structural strength and the appearance of a finished product are influenced. In addition, the welding process lacks a multi-angle welding design, and the accurate welding requirement of metal furniture parts with complex structures is difficult to meet. Therefore, the requirements of improving the positioning precision and the welding angle adaptability on the welding equipment are higher.
The welding quality is unstable, the subsequent treatment is complex, and the welding quality of the existing equipment is easily influenced by the external environment and the precision of the equipment due to unstable positioning and limited welding process, so that the problems of uneven welding seams, insufficient welding strength and the like can occur. The method not only affects the structural performance of the metal furniture, but also increases the subsequent polishing, calibration and other treatment procedures, further reduces the production efficiency and increases the production cost.
In summary, the current metal furniture welding equipment has defects in continuous production capacity, operation simplicity, positioning accuracy and welding quality, and is difficult to meet the requirements of the modern metal furniture industry on mass and high-quality production.
