Assessment oncutting quality of the cut-to-length line of transformer
1
铁芯结构和铁芯片要设计合理,便于自动化冲剪、叠装。尽可能不用穿心螺孔;

Iron core structure and iron core chip shouldbe properly designed to facilitate automatic punching shear. Penetrated boltshould be used as few as possible.
2
要尽可能采用先进工模具和先进生产线生产;

Every effort should be taken for applyingadvanced tools and moulds as well as advanced production line;
3
卷料或片料堆放要合理,搬运、吊装要轻拿、轻放,防止划伤、磕破、弯曲或断头;

Roll material or sheet stock should bestacked properly, and handled and lifted with care in order to avoid scratch,damage, break, bend or division.  
4
冲剪后的片料要求摆放平坦整齐,刃口处要喷防锈漆;

The sheared sheet stock should be placedevenly and tidily with its edge coated by anti-rust paint.
5
毛刺过高时,要及时调整刀具、模具间隙,或重磨、跟换刀具、模具,已经加工好的毛刺又过大的片子,必须进行压毛或用其他去毛设备去除;

In case of long burr, you need immediatelyadjust the gap between knife and mould, or regrind, or replace the knife/mould.In case any sheet material that was processed has too large burr, it should bepressed down or removed by other device;
6
个别弯片必须理平,不可转入下道工序;

Individual bent sheet should be evened andnot allowed to the next step;
7
片料直线度、弧度、波浪度应在纵剪时或纵剪前调整或去除。在加工设备上纠正这些是不可能的;

Any straightness, radian, wave of the sheetstock should be adjusted or removed when or before vertical shearing. And it isimpossible to correct it on the processing equipment;  
8
仔细调整加工设备和模具的各个环节,使其尺寸精度和毛刺等均在质量标准规定的范围内;

Each aspect of processing equipment andmoulds should be regulated carefully to get their accuracy and burr to conformto relevant quality standards.
9
在剪切片料时要注意轧制方向;

Pay attention to the direction of cuttingwhen shearing sheet material;
10
预叠时要严格选片,把不合格片子挑出去。

When pre-stacking, it is necessary tostrictly select the sheet and pick out the defective ones
