2) blanking hole chamfering, increase the feeding hole chamfering removal
3）刀口未放锥度，线割锥度或反面扩充孔减小直壁位长度
3) no taper, line cut taper, or reverse side expansion hole to reduce the length of the straight wall
4）刀口直壁位过长，反面钻孔，使刀口直壁位缩短
4) the straight wall position of the knife edge is too long and the reverse side is boring, so the straight wall position of the knife edge is shortened.
5）刃口崩，造成披锋大，堵料重新研磨刃口
5) blade avalanche, leading to large draping fronts and regrinding the edge of the material
3. 披锋不良
3. winger is bad
1）刃口崩，造成披锋过大重新研磨刃口
1) blade avalanche, which causes the oversize of the front to regrind the edge
2）冲头与凹模间隙过大，线割入块，重新配间隙
2) the gap between the punch and the die is too large, the line is cut into the block, and the gap is rearranged.
3）凹模刀口光洁度差，抛光刀口直壁位
3) the aperture of the concave die is poor, and the vertical wall position of the polishing knife
4）冲头与凹模间隙过小，重新省模，配间隙
4) the gap between the punch and the die is too small, and the die is re saved and the gap is matched.
5）顶料力过大，反向拉出披锋换弹簧，减小顶料力
5) the overburden force is too large, and the reverse pull out the spring to change the spring to reduce the force of the material
4. 切边不齐
4. trimming of edge
1）定位偏移调整定位
1) positioning offset adjustment and positioning
2）有单边成型，拉料加大压料力，调整定位
2) there is a single side forming, the pulling material increases the pressure of the material, and the positioning is adjusted.
3）设计错误，造成接刀不平重新线割切边刀口镶块
3) design errors, caused by the knife edge cutting edge uneven line to insert
4）送料不准调整送料器
4) are not allowed to adjust the feeding feeder
5）送料步距计算有误重新计算步距，重定接刀位
5) the calculation of the feed step distance has the error recalculating step distance and relocating the cutter position
5. 冲头易断
5. punch is easy to break
1）闭合高度过低，冲头切入刀口部位过长调整闭合高度
1) the closed height is too low, and the punch cut into the edge of the knife to adjust the closed height
2）材料定位不当，造成冲孔冲头切单边，调整定位或送料装置因受力不均断裂
2) the improper positioning of the material causes the punching punch to cut off the single side, and the adjustment of the positioning or feeding device is caused by the unequal stress of the force.
3）下模废料堵死刀口，造成冲头断重新钻大落料孔，使落料顺畅
3) die waste caused by blocked knife, punch off re drilling large blanking holes, smooth blanking.
4）冲头的固定部位（夹板）与导向部位修配或重新线割入块使冲头上下顺畅（打板）偏移
4) fixed part of the punch (plywood) and steering parts repair or re cut into blocks a punch on the smooth (a) offset
5）打板导向不良，造成冲头单边受力重新修配打板间隙
5) a bad guide, caused by unilateral stress to repair a punch gap
6）冲头刀口太短，与打板干涉重换冲头，增长刀口部分长度
6) the punch edge is too short, and a heavy punch for interference, increase length of blade
7）冲头固定不好，上下窜动重新固定冲头使之不能上下窜动
7) the punch is not good, and it moves up and down to refix the punch so that it can't move up and down.
8）冲头刃口不锋利重新研磨刃口
8) the cutting edge of the punch is not sharp and regrinding the edge
9）冲头表面拉伤，脱料时受力不均重新换冲头
9) pull the head of the punch and replace the punch with the force unevenly
10）冲头过细，过长，强度不够重新换冲头类型
10) the punch is too small, too long, the strength is not enough to change the type of punch
11）冲头硬度过高，冲头材质不对更换冲头材质，调整热处理硬度
11) the hardness of the punch is too high, the punch material does not change the material of the punch and adjusts the hardness of the heat treatment.
6. 铁屑
6. iron chips
1）压筋错位重新计算压筋位置或折弯位置
1) recalculation of position or bending position of tendons
2）折弯间隙过小，挤出铁屑重新调整间隙，或研磨成型块，或研磨成型冲头
2) the bending gap is too small, and the extruded iron chips are re adjusted, or grinding blocks, or grinding punches.
3）折弯凸模太锋利修R角
3) the bending punch is too sharp to repair R angle
4）接刀口材料太少重新接刀口
4) the cutting edge material is too little to reconnect the knife edge
5）压筋太窄重新研磨压筋
5) it is too narrow to rebar and rebar the tendons |
