Blanking & Unloading Of Edge Milling Machines

Because of its high working frequency, the edge milling machine has the advantages of small size, lightweight, energy saving, material saving, fast dynamic response, high efficiency, good welding performance, multi-function, and is conducive to the realization of welding mechanization and automation. It is gradually becoming the mainstream of welding and cutting equipment.

Judging from the production and sales of inverter welding and cutting equipment in my country, the output of inverter welding and cutting equipment is growing at a rate of about 20% per year, which is much higher than the growth rate of traditional welding and cutting equipment. Inverter welding and cutting equipment replace traditional welding and cutting equipment. The trend of cutting equipment is obvious. Welding automation is to achieve high-efficiency, high-quality, low-cost batch-scale welding operations on workpieces through the organic integration of advanced welding processes, materials, equipment, automatic control systems, welding fixtures, clamping positioning, and motion systems. , to ensure consistent and stable batch output of high-quality products. Faced with the huge workload of hundreds of millions of tons of steel that needs to be welded each year and the rising labor costs, the pursuit of welding automation and efficient welding will become the main direction of welding innovation in the next step.

1. The C-shaped single-column press will deflect the angular wave mode during welding, while the double-column edge milling machine has a stable structure, and the action is accurate according to the size of the workpiece and the load (centering or eccentricity) of the weld, and there is very little deflection, suitable for eccentric load processing. Likewise, setting the preload on the edger is simple.

2. At present, the productivity requirements are relatively low, and edge milling machines are generally used for blanking small and medium-sized parts, and the production cycle is generally not more than 20-40 pieces per minute. The four-column edge milling machine has a deflection of the action point of its force and its geometric center. Whether it is a two-column or four-column press, its body structure must be able to withstand the shock and vibration caused by blanking, and the molding method determines the structure of the edge milling. C-shaped frame.

3. The buffer function (the press may be damaged when pressing two pieces) can only find out the benefits of using the edge milling machine. Only by knowing whether the adjustment of the stroke range of the slider and the control of the welding seam meets the processing requirements. Preload is used to offset the impact of workpiece weight or emergency stop. The device failed to eject the machined part. When designing the press, when two pieces of material are put on the mold when feeding, or when the mold is ejected, the setting of the edge milling machine is very difficult. If the stroke range is set, the milling machine should be selected.

4. When there is such a requirement, use the edge milling machine to quickly change the settings;

(1) For products with diverse types, complex program settings are often required, which are easy to set up with an edge milling machine; the frequency of JIT component replacement is high;

(2) When the program setting is more complicated to process small pieces (1-2 inches), the beat is 60spm, and when processing large pieces (3-15 inches), the beat is 30-40spm; the production beat of the edge milling machine is slower;

(3) For the blanking process that meets the following requirements, it is ideal to use an edge milling machine:

At this time, it is possible to cause double pressing to improve its firmness. In this case, the mechanical press may be damaged to reduce the impact of blanking. Designers often design blanking presses to be twice as heavy as the standard configuration. The edge milling machine has an overload protection function, which limits the highest welding port, so it will not be damaged.
