Technical Field

Background

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention aims to provide a parameter segmentation design method and a parameter segmentation design system for bipolar double-station welding equipment, which can ensure that the welding equipment runs at the optimal welding parameters in each welding time period and improve the welding quality.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

In the original bipolar double-station application process, the welding voltage cannot be changed (the secondary voltage of the alternating-current transformer), and the welding process always uses fixed current and the fusion welding speed of the polar plate. Aiming at the problem, the invention increases the sectional control of current, welding speed and welding time.

FIG. 1 is a flow chart of a parameter segmentation design method of the bipolar double-station welding equipment. As shown in fig. 1, a parameter segmentation design method for bipolar double-station welding equipment includes:

step 101: segmenting the welding area, specifically comprising:

the welding area is segmented into six different sub-welding areas, wherein the sub-welding areas comprise a first welding area, a second welding area, a third welding area, a fourth welding area, a fifth welding area and a sixth welding area.

And calling a special PID control program block in the PLC, setting a PID parameter area, and setting a proportion P value and an integral I value of the PID. The input of the PID program is a current value set by a touch screen (the current value in step 1021 and 1026), the given values of the seven sections are converted by six sections of time, namely, the given current value of the first section parameter area is automatically switched to the given current value of the second section for operation after the set operation time of the first section, and so on until the operation of the last sixth section is finished; the output value of PID is the electrode plate descending frequency, and the maximum electrode descending frequency is set in the steps 1021-1026. The current feedback value of the PID program block is a numerical value which is transmitted to the interior of the PLC after the actual value of the welding current is converted into a standard signal, and the range is 0-10V.

Step 102: welding the segmented welding area by adopting different current values, different frequency values and different welding times, and fig. 2 is a welding flow chart of the present invention, as shown in fig. 2, step 102 specifically includes:

step 1021: welding the first section of welding area by adopting a given current value of 1500A, an electrode descending maximum frequency of 3.5HZ and a welding time of 30 seconds;

step 1022: welding a second section of welding area by adopting a given current value of 1800A, the maximum electrode dropping frequency of 3.8HZ and the welding time of 60 seconds;

step 1024: welding a fourth welding zone with a given current value of 2200A, a maximum electrode lowering frequency of 4.5HZ and a welding time of 180 seconds;

step 1025: welding a fifth welding area by adopting a given current value of 2800A, an electrode descending maximum frequency of 5.5HZ and a welding time of 180 seconds;

step 1026: the sixth weld zone was welded using a given current value of 3200A, a maximum frequency of electrode descent of 6.5HZ and a welding time of 210 seconds.

The parameters set by the touch screen are sent to the PLC as the given value of PID operation, namely the given value of current. The current detection signal is sent to the PLC analog quantity module as a PID feedback parameter. The feedback value is not processed, and the given value is set in sections according to the production running time. At present, the production time is generally about 12 minutes, and the production time is divided into 6 sections (not divided into equal sections, but divided into sections according to the smelting state) for 12 minutes. Within the six-stage process parameters, the given current value is automatically changed according to the process; meanwhile, the welding speed of the pole plate is automatically adjusted according to the output and the output proportion of the PID.

Step 103: and stopping welding when the total welding time reaches a set value. And after welding is finished (according to timing time), automatically stopping welding the power supply of the voltage transformer, and waiting for an operator to perform manual demoulding operation.

After long-time tests and trial production, the special welding section parameters are designed and summarized according to the welding quality of each part of the welded and formed steel claw, and the welding quality is remarkably improved through repeated tests and production.
