Automatic plasma welding device for welding of stainless hollow cutter bar

Abstract

The invention provides an automatic plasma welding device for welding of a stainless hollow cutter bar. The automatic plasma welding device is mounted on a support of a steel structure and comprises a cutter bar clamping mechanism, a cutter bar rotating mechanism, a plasma welding gun traveling mechanism, and a plasma welding mechanism. The cutter bar clamping mechanism is used for clamping two pieces of cutter bar shells and positioning the same. The cutter bar rotating mechanism used for rotary welding during cutter bar welding is mounted in the cutter bar clamping mechanism. The plasma welding gun traveling mechanism is used for allowing plasma beams to follow welding seams for three-dimensional trajectory traveling welding. A plasma welding gun is mounted on a support on which the plasma welding gun traveling mechanism, namely, a three-axis mechanical mechanism (X-axis, Y-axis and Z-axis) is mounted. The plasma welding mechanism uses a multi-axis motion control system. The automatic plasma welding device is simple in structure, fine and smooth in welding effect, fast and easy to operate, low in cost and the like.

Description

technical field [0001] The invention belongs to the field of kitchen utensil production welding, and in particular relates to a welding device for stainless steel hollow handles of kitchen utensil knives. Background technique [0002] At present, in the process of welding prefabricated parts of stainless steel hollow handles of kitchen utensils and knives, there are many prefabricated parts with different sizes and shapes, many changes, many welding curves, and large quantities. Special automatic machinery is required to be suitable for production. [0003] The welding of traditional stainless steel hollow knife handle prefabricated parts is made by manually fixing the position for manual argon arc protection welding; it is completed in two processes. Smooth argon arc shielded welding is used for the butt joint; the welder's technical and personal conditions are very high in order to weld smoothly. [0004] Existing automatic welding machines cannot be used in the productio...

AI Technical Summary

Problems solved by technology

[0004] None of the existing automatic welding machines can be used in the production of stainless steel hollow handles, only for demonstration

The main reason is that the machine is unstable - bad welds

[0005] To sum up, most of the existing welding devices are not suitable for welding stainless steel hollow handles, and it is urgent to develop a low-cost, high-automation welding machine suitable for welding stainless steel hollow handles.
