Full-automatic single-wheel numerical control circling welding machine and circling welding method thereof

Abstract

The invention relates to a full-automatic single-wheel numerical control circling welding machine which comprises a machine body and a working table. The full-automatic single-wheel numerical control circling welding machine is characterized in that the machine body is sequentially provided with a straightening mechanism, a feeding mechanism, a guide line plate, a cut-off device, a single-wheel forming mechanism and a butt-weld mechanism according to the processing sequence, and the single-wheel forming mechanism comprises a forming wheel which conducts contour machining on workpieces. According to the full-automatic single-wheel numerical control circling welding machine, the single forming wheel is used for achieving contour machining, flexible adjusting of the specifications of machining parts is achieved, a starting point cutter device is used so that starting point cutting-off can be achieved in the machining process, errors caused by a cutter can be reduced, the butt-weld mechanism can effectively guarantee the welding precision and firmness, and therefore workpiece quality is guaranteed.

Description

technical field [0001] The invention relates to a loop welding machine, which belongs to the field of material forming equipment, and in particular refers to a loop welding operation method of a fully automatic single-wheel numerical control loop welding machine. Background technique [0002] As a commonly used wire forming equipment, the looping machine is widely used in many fields such as hardware, home appliances, and dust removal. Among the various circle making machines currently used in the market, the adjustment method of the diameter is mechanical manual adjustment. Every time the product model is changed, it takes a lot of time to adjust the forming device on the equipment. Not only is the operation cumbersome, but also the mechanical manual adjustment The effect of adjustment is also not good, and it is difficult to adjust the circumference of the circle and the length of the wire to be consistent. After the circle is finished, manual butt welding is required, and...

Problems solved by technology

Its patent enables the adjustment of the circumference and diameter of the processing ring to be realized through the control of the servo motor and the stepping motor on the transmission mechanism and the forming mechanism respectively. The servo motor and the stepping motor are connected with the digital control system, and the numerical control system is adopted. Ensure the consistency between the circumference of the processing ring and the length of the wire, and automatically butt weld the formed metal ring; but in the technical solution disclosed in the above patent document, it has the following disadvantages: 1. During forming, It is formed by at least two pressure wheels and forming wheels, so according to the diameters of different metal rings, the relative positional relationship between the three needs to be adjusted. Such adjustments are cumbersome, and the diameter error is large, which affects the processing quality of the workpiece; 2. Its processing steps are numerous, resulting in a large accumulation of errors, which further affects its accuracy; 3. During welding, due to the problem of multiple reference planes, the welding positions will be staggered, which will affect its accuracy and also affect its firmness. degree, and generally such workpieces will be scrapped
