一、从废料情况看出的信息
1、 Information from waste situation
废料本质上就是成形孔的反像。即位置相反的相同部位。通过检查废料,你可以判断上下模间隙是否正确。如果间隙过大,废料会出现粗糙、起伏的断裂面和一窄光亮带区域。间隙越大,断裂面与光亮带区域所成角度就越大。如果间隙过小,废料会呈现出一小角度断裂面和一宽光亮带区域。
Waste is essentially the reverse image of the forming hole. That is to say, the same position opposite to each other. By checking the scrap, you can judge whether the clearance between the upper and lower die is correct. If the gap is too large, the waste will appear rough, undulating fracture surface and a narrow bright zone area. The larger the gap, the larger the angle between the fracture surface and the bright zone. If the gap is too small, the waste will show a small angle fracture surface and a wide bright zone area.
过大间隙形成带有较大卷边和边缘撕裂的孔,令剖面稍微有一薄边缘突出。太小的间隙形成带稍微卷边和大角度撕裂,导致剖面或多或少地垂直于材料表面。
The large gap forms a hole with large curling and edge tearing, which makes the profile slightly protrude with a thin edge. Too small gaps form a band with a slight curl and a large angle tear, resulting in a profile that is more or less perpendicular to the surface of the material.
一个理想的废料应有合理的压塌角和均匀的光亮带。这样可保持冲压力更小并形成一带极少毛刺的整洁圆孔。从这点来看,通过增大间隙来延长beplay全站app安卓寿命是以牺牲成品孔质量换取的。
An ideal waste material should have a reasonable collapse angle and a uniform bright band. In this way, the punching pressure can be kept to a minimum and a clean round hole with few burrs can be formed. From this point of view, increasing the gap to extend the life of the die is at the expense of the quality of the finished hole.
二、beplay全站app安卓间隙的选择
2、 Selection of die clearance
beplay全站app安卓的间隙与所冲压的材料的类型及厚度有关。不合理的间隙可以造成以下问题:
The clearance of the die is related to the type and thickness of the material being punched. Unreasonable clearances can cause the following problems:
(1)如间隙过大,所冲压工件的毛刺就比较大,冲压质量差。如果间隙偏小,虽然冲孔的质量较好,但beplay全站app安卓的磨损比较严重,大大降低beplay全站app安卓的使用寿命,而且容易造成冲头的折断。
(1) If the gap is too large, the burr of the stamping workpiece is relatively large, and the stamping quality is poor. If the gap is small, although the quality of punching is good, the wear of the die is serious, which greatly reduces the service life of the die, and it is easy to break the punch.
(2)间隙过大或过小都容易在冲头材料上产生粘连,从而造成冲压时带料。过小的间隙容易在冲头底面与板料之间形成真空而发生废料反弹。
(2) If the gap is too large or too small, it is easy to produce adhesion on the punch material, resulting in the strip material during stamping. If the gap is too small, it is easy to form a vacuum between the bottom of the punch and the sheet metal, and the waste will rebound.
(3)合理的间隙可以延长beplay全站app安卓寿命,卸料效果好,减小毛刺和翻边,板材保持洁净,孔径一致不会刮花板材,减少刃磨次数,保持板材平直,冲孔定位准确。
(3) Reasonable clearance can prolong the service life of the die, have good unloading effect, reduce burr and flanging, keep the plate clean, the hole diameter is the same and will not scratch the plate, reduce the grinding times, keep the plate straight and the punching positioning is accurate.
三、如何提高beplay全站app安卓的使用寿命
3、 How to improve the service life of mould
对用户来讲,提高beplay全站app安卓的使用寿命可以大大降低冲压成本。影响beplay全站app安卓使用寿命的因素如下:
For users, increasing the service life of the die can greatly reduce the stamping cost. The factors affecting the service life of the mould are as follows:
1、材料的类型及厚度;
1. Type and thickness of material;
2、是否选择合理的下模间隙;
2. Whether to choose a reasonable die clearance;
3、beplay全站app安卓的结构形式;
3. Mold structure;
4、材料冲压时是否有良好的润滑;
4. Whether the material is well lubricated during stamping;
5、beplay全站app安卓是否经过特殊的表面处理;
5. Whether the mold has undergone special surface treatment;
6、如镀钛、碳素氮化钛;
6. Such as titanium plating, titanium nitride;
7、上下转塔的对中性;
7. Neutral of up and down rotating tower;
8、调整垫片的合理使用;
8. Reasonable use of adjusting gasket;
9、是否适当采用斜刃口beplay全站app安卓;
9. Whether the inclined edge die is properly used;
10、机床模座是否已经磨损;
10. Whether the die seat of the machine tool has been worn;
四、冲压特殊尺寸孔应注意的问题
4、 Problems in stamping special size holes
(1)更小孔径冲φ0.8——φ1.6范围的冲孔请用特殊冲头。
(1) Minimum diameter punch φ Zero point eight ——φ One point six Please use a special punch for range punching.
(2)厚板冲孔时,相对于加工孔径,请使用大一号的beplay全站app安卓。注意:此时,若使用通常大小的beplay全站app安卓,会造成冲头螺纹的破损。
(2) When punching thick plates, please use a larger die relative to the machining hole diameter. Note: at this time, if the die of normal size is used, the thread of punch will be damaged.
(3)冲头刃口部分,更小宽度与长度的比例一般不应小于1:10。
(3) The ratio of minimum width to length of the cutting edge of punch shall not be less than 1:10 in general.
(4)冲头刃口部分更小尺寸与板厚的关系。建议冲头刃口部分更小尺寸取板厚的2倍。
(4) The relationship between the minimum size of the cutting edge and the thickness of the plate. It is suggested that the minimum size of the cutting edge of the punch should be 2 times of the plate thickness.
五、beplay全站app安卓的刃磨
5、 Grinding of die
1、beplay全站app安卓刃磨的重要性
1. The importance of die grinding
定期刃磨beplay全站app安卓是冲孔质量一致性的保证。定期刃磨beplay全站app安卓不仅能提高beplay全站app安卓的使用寿命而且能提高机器的使用寿命,要掌握正确的刃磨时机。
Regular grinding of die is the guarantee of punching quality consistency. Regular grinding of the die can not only improve the service life of the die, but also the service life of the machine.
2、beplay全站app安卓需要刃磨的具体特征
2. The specific characteristics of the tool need to be sharpened
对于beplay全站app安卓的刃磨,没有一个严格的打击次数来确定是否需要刃磨。主要取决于刃口的锋利程度。主要由以下三个因素来决定:
There is not a strict number of blows to determine whether the edge grinding is needed. It mainly depends on the sharpness of the edge. It is mainly determined by the following three factors:
(1)检查刃口的圆角,如果圆角半径达到R0.1毫米(R值不得超过0.25毫米)就需要刃磨。
(1) Check the fillet of the cutting edge, if the fillet radius reaches R0.1 Mm (maximum r value shall not exceed zero point two five Mm).
(2)检查冲孔质量,是否有较大的毛刺产生?
(2) Check the punching quality. Is there any big burr?
(3)通过机器冲压的噪声来判断是否需要刃磨。如果同一副beplay全站app安卓冲压时噪声异常,说明冲头已经钝了,需要刃磨。
(3) The need for grinding is judged by the noise of machine stamping. If the noise of the same die is abnormal, it means that the punch is blunt and needs to be sharpened.
注:刃口边缘部变圆或刃口后部粗糙,也要考虑刃磨。
Note: if the edge of the cutting edge becomes round or the back of the cutting edge is rough, the grinding of the cutting edge should also be considered.
3、刃磨的方法
3. Method of sharpening
beplay全站app安卓的刃磨有多种方法,可采用专用刃磨机也可在平面磨床上实现。冲头、下模刃磨的频度一般为4:1,刃磨后请调整好beplay全站app安卓高度。
There are many ways to grind the die, which can be realized by using special grinding machine or plane grinding machine. The grinding frequency of punch and lower die is generally 4:1. Please adjust the die height after grinding.
(1)不正确刃磨方法的危害:不正确的刃磨会加剧beplay全站app安卓刃口的迅速破坏,致使每次刃磨的打击次数大大缩小。
(1) Harm of incorrect grinding method: incorrect grinding will aggravate the rapid damage of the die edge, resulting in a greatly reduced number of blows per grinding.
(2)正确的刃磨方法的益处:定期刃磨beplay全站app安卓,冲孔的质量和精度可以保持稳定。beplay全站app安卓的刃口就损坏较慢,寿命更长。
(2) The benefits of the correct grinding method: regular grinding of the die, punching quality and accuracy can be maintained stable. The cutting edge of the die is damaged slowly and has a longer service life.
4、刃磨规则
4. Sharpening rule
beplay全站app安卓刃磨时要考虑下面的因素:
The following factors should be considered when grinding the die edge:
(1)刃口圆角在R0.1-0.25毫米大小情况下要看刃口的锋利程度。
(1) The edge fillet is R0.1 - zero point two five The sharpness of the edge depends on the size of millimeter.
(2)砂轮表面要清理干净。
(2) The grinding wheel surface shall be cleaned.
(3)建议采用一种疏松、粗粒、软砂轮。如WA46KV
(3) A loose, coarse and soft grinding wheel is recommended. Such as wa46kv
(4)每次的磨削量(吃刀量)不应超过0.013毫米,磨削量过大会造成beplay全站app安卓表面过热,相当于退火处理,beplay全站app安卓变软,大大降低beplay全站app安卓的寿命。
(4) The grinding amount (cutting amount) of each time shall not exceed zero point zero one three Mm, too much grinding will cause the die surface overheating, equivalent to annealing treatment, the die becomes soft, greatly reducing the life of the die.
(5)刃磨时必须加足够的冷却液。
(5) Enough coolant must be added during grinding.
(6)磨削时应保证冲头和下模固定平稳,采用专用的工装夹具。
(6) During grinding, the punch and lower die shall be fixed stably, and special tooling and fixture shall be used.
(7)beplay全站app安卓的刃磨量是一定的,如果达到该数值,冲头就要报废。如果继续使用,容易造成beplay全站app安卓和机器的损坏,得不偿失。
(7) The grinding amount of the die is certain. If it reaches this value, the punch will be scrapped. If continue to use, easy to cause mold and machine damage, the gain is not worth the loss.
(8)刃磨完后,边缘部要用油石处理,去掉过分尖锐的棱线。
(8) After grinding, the edge shall be treated with oilstone to remove the excessively sharp edges.
(9)刃磨完后,要清理干净、退磁、上油。
(9) Clean, demagnetize and oil the blade after grinding.
注:beplay全站app安卓刃磨量的大小主要取决于所冲压的板材的厚度。
Note: the grinding amount of the die edge mainly depends on the thickness of the plate to be punched.
