弯曲模具设计(带全套cad图)
模具课程设计说明书——弯曲模课程设计学校：学院：专业：姓名：学号：指导教师：一、零件图二、工艺设计1.弯曲工序安排原则工序安排的原则应有利于坯件在模具中的定位；工人操作安全、方便；生产率高和废品率最低等。
弯曲工艺顺序应遵循的原则为：①先弯曲外角，后弯曲内角。
②前道工序弯曲变形必须有利于后续工序的可靠定位；并为后续工序的定位做好准备。
③后续工序的弯曲变形不能影响前面工序已成形形状和尺寸精度。
④小型复杂件宜采用工序集中的工艺，大型件宜采用工序分散的工艺。
⑤精度要求高的部位的弯曲宜采用单独工序弯曲，以便模具的调整与修正。
制订工艺方案时应进行多方案比较。
2.形状简单的弯曲件如V形、U形、Z形件等，可采用一次弯曲成形。
3.弯曲件展开尺寸计算。
（1）中性层位置的确定弯曲中性层位置并不是在材料厚度的中间位置，其位置与弯曲变形量大小有关，应按下式确定：P=r+kt式中 P----弯曲中性层的曲率半径；r----弯曲件内层的弯曲半径；t----材料厚度；k----中性层位移系数，板料可有表3-9查得，圆棒料由表3-10查得。
（2）弯曲件展开尺寸计算计算步骤：1）将标注尺寸转换成计算尺寸即将工件直线部分与圆弧部分分开标注，2）计算圆弧部分中性层曲率半径及弧长中性层曲率半径为P=r+kt，则圆弧部分弧长为： s=Pa式中 a----圆弧对应的中心角，以弧度表示。
3）计算总展开长度L=L1+L2+SL=∑L直+∑S弧4.回弹弯曲成形是一种塑性变形工艺。
回弹的表现形式：1）弯曲回弹会使工件的圆角半径增大，即r2＞rp,则回弹量可表示为△r=r2-rp2) 弯曲回弹会使弯曲件的弯曲中心角增大，即a＞ap.则回弹量可表示为△a=a-ap影响弯曲回弹的因素：1．材料的力学性能。
2. 材料的相对弯曲半径r/t。
3. 弯曲制件的形状。
4. 模具间隙。
5. 校正程度。
弯曲板件时，凸模圆角半径和中心角可按下式计算:Rp=r/(1+3Asr/Et)ap=ra/rp式中 r----工件的圆角半径；Rp----凸模的圆角半径；a----工件的圆角半径r对弧长的中心角；ap----凸模的圆角半径rp所对弧长的中心角；t----毛坯的厚度；E----弯曲材料的弹性模量；A----弯曲材料的屈服点减小回弹的措施：1）在弯曲件的产品设计时①弯曲件结构设计时考虑减少回弹，在弯曲部位增加压筋连接带等结构。

Failure to comply may cause serious injury.6.1 Unpacking and cleanupInspect contents of shipping container for shipping damage. Report any damage to your distributor. Remove all contents from carton, and compare to the contents list in this manual. Report any part shortages to your distributor.Do not discard carton or packing material until machine is assembled and working properly. Exposed metal areas may have a rust protectant applied. Remove this with a soft rag and solvent such as kerosene. (Do not use gasoline, paint thinner, acetone, etc., as these will damage painted surfaces.)6.2 Contents of shipping container1 Box and Pan Brake2 Support legs with screws1 Instructions and Parts Manual (not shown)1 Warranty Card (not shown)6.3 Tools required for assembly8mm hex key6.4 AssemblyNumbers in parentheses refer to items in Figure 2. 1. Remove any straps or screws securing thebrake, and raise machine using properly ratedlifting equipment. See Figure 3 for lifting strapplacement.Figure 3Continue to stabilize machine while installing support legs. 2. Attach the two leg extensions (11) with theprovided socket head screws and flat washers. 3. Secure brake to floor using lag screws or similarsystem. See diagram, Figure 1. Also level thebrake; use shims if needed.4. The stop collar screw (16) has been tightenedfor shipping purposes. This screw must beloosened to allow clamping machine adjustments.7.0 OperationNumbers in parentheses refer to items in Figure 2. 7.1 Finger spacingUpper (2) and lower (7) fingers are mounted on T-nuts that slide within the underlying channel. Remove fingers by removing the screw(s); or reposition fingers at any place along the beam by loosening screw and sliding the T-nuts. Firmly tighten screws on fingers before operating.7.2 Adjusting setbackThe bending leaf lower fingers (7) must be adjusted for proper clearance or “setback” (A, Figure 3) based on material thickness (B, Figure 3). Generally, setback for material within four gauges of capacity should be twice the thickness of material. For lighter gauges, use 1-1/2 times the material thickness. Consult a machinery handbook for bend allowances.Figure 31. Loosen setback locking screws (5).2. Rotate setback knobs (6) in equal amounts(clockwise decreases distance). Refer to adjoining scale, marked with 0.002-inch graduations.Note: When increasing distance (counter-clockwise), you may have to pull back slightlyon the bending leaf to take up any backlash.3. Bring clamping leaf into position and checksetback.4. Repeat above steps until proper distance isachieved.5. Tighten locking screws (5).If a crown develops in the material, this can be adjusted out by loosening or tightening the hex nuts on the crown adjustment rod (12). Note: This rod has been correctly set by the manufacturer and should only be adjusted when needed.7.3 Adjusting clamping pressure Clamping pressure may vary depending upon material gauge. Pressure should be great enough to hold material securely, but not so much that it becomes difficult to clamp.Rotate clamping adjustment nuts (3) equally to set clamping pressure. Proper adjustment will allow foot pedal (9) to be locked (10).7.4 Repeat bendsLoosen stop collar screw (16) and adjust stop bolt (4) to limit swing of bending leaf. Retighten screw (16).7.5 General procedure1. Adjust upper and/or lower fingers for width ofmaterial and type of bend.2. Adjust for setback and clamping pressure.3. Position stop bolt if needed.4. Align material in machine and press foot pedaluntil it locks.5. Raise bending leaf to desired angle.6. Lower bending leaf and press foot pedal lock torelease material.8.0 User-maintenance Periodically wipe down machine with a soft rag. Keep upper and lower fingers clean and clear of debris. Apply light coat of SAE30 oil to upper and lower fingers.Periodically check tightness of fasteners.8.1 LubricationDaily insert a multi-purpose grease into the two fittings (14).Lightly apply grease to pivot points around machine, such as setback rods and eccentric disc.Apply light coat of SAE30 oil to all machined (unpainted) parts when not in use, to inhibit rust. 8.2 Additional servicingAny additional servicing should be performed by an authorized service technician.9.0 Troubleshooting PBF-1650D Box and Pan Brake Symptom PossibleCause CorrectionBends created with great difficulty.Machine capacity exceeded. Use material within capacity. Incorrect setback. Increase setback.Clamping leaf will not clamp properly.Improper adjustment.Decrease distance between fingers andbeam.Clamping not even across width. Rotate adjustment nuts equal amount.Bend radius not consistent across material.Machine capacity exceeded. Use material within capacity.Bending leaf edge not parallel to fingers. Adjust bending leaf equally on both ends. Bending leaf has crown. Correct with crown adjustment rod.10.0 Replacement PartsReplacement parts are listed on the following pages.

弯曲负责：郑勇黄洋
班级：机械（汽车）
2.材料板弯曲模设计
2.1材料板弯曲工艺性分析
图2—1
弯曲是使材料产生塑性变形、形成有一定角度形状零件的冲压工序。
弯曲工序可以用模具在普通压力机上进行，也可以在专用的弯曲机上或弯曲设备上进行。
具有良好的工艺性的弯曲件，不仅能简化弯曲工艺过程和模具设计，而且能够提高弯曲件的精度和节省材料。
具有良好工艺性的弯曲件，不仅能简化弯曲故意过程和模具设计，而且能提高弯曲件精度和节省材料。
弯曲件的工艺性可以从最小弯曲半径，弯曲件直边高度，弯曲件孔边距离，增添工艺孔，槽和转移弯曲线，连接带和定位工艺孔，弯曲件的精度等几个方面进行分析：
由零件图2-1所示，材料板属于板材弯曲。
材料板厚度1.6mm,内弯曲半径是R0.5 mm，弯曲角度成90º，弯边长130.3mm，符合弯曲的工艺性要求，角度回弹量Δθ=7º，足以达到制件精度质量要求。
2.2模具结构方案的确定
弯曲零件常见的模具结构有以下几种。
如图2—2所示：
图2—2 弯曲模结构方案示意图
鉴于本零件的实际要求，及相关的定位和精度要求，以上几种方案图中，图（b）能够达到设计要求，结构清晰、简单、可行性高。
具体设计如下图2—3：

2.4材料板弯曲件的回弹
1）压弯过程并不完全是材料的塑性变形过程，其弯曲部位还存在着弹性变形。
弯曲工件从模具中取出后，由于弹性变形的恢复，使工件的弯角和弯曲半径发生变化，所以被弯曲零件的形状与模具的性质不完全一致，这种现象称为回弹。
回弹的大小通常用角度回弹量Δα和曲率回弹Δρ来表示。
2）影响回弹的因素
（1）材料的力学性能角度回弹量及曲率回弹量与材料的屈服点σs成正比，与弹性模量E成反比。
（2）材料的相对弯曲半径R/t 当其他条件相同时，R/t值越小，则：Δα/α与Δρ/ρ也越小。
（3）弯曲工件的形状 一般弯制U 形工件要比弯制V 形工件的回弹量要小。
（4）模具间隙 在弯曲U 形工件时，凸模与凹模之间的间隙越小，则回弹量越小；Z/2<t 时，可能产生负回弹。
（5）校正弯曲时的较正力 校正力小，回弹量大，增加校正力可减小回弹量。
3） 回弹量的确定
由于影响角度回弹量数值的因素较多，而各种因素又互相影响，理论分析计算较复杂，且不够精确，所以在一般的情况下，设计模具时对回弹量的确定大多按照经验数值，计算后在实际试模中再进行修正。
只有当弯曲工件的圆角半径R 》（5-8）t 时，计算才近似正确。
当R <（5-8）t 时，工件的弯曲半径一般变化不大，只考虑角度回弹。
本零件的R=1.6，远小于（5-8）t=10-16 mm,只考虑角度回弹量Δα，查角度回弹的经验数值表可得：
Δα=7 º
2.5弯曲模工作部分的设计
2.5.1 弯曲时凸模与凹模之间的单边间隙C 弯曲U 形件时，凸，凹模间隙对弯曲件的回弹、等有很大影响。
间隙越小，弯曲力越大；间隙过小，会使工件壁变薄，并降低凹模寿命；间隙过大，则回弹较大。
当C<t 时，可能出现负回弹。
间隙值C 一般按经验公式进行计算：对钢板，C=（1.05—1.15）t
取C=1.1t=1.1X1.6=1.76 mm
2.5.2 凸，凹模工作部分尺寸 按零件内形尺寸计算，模具以凸模为基准，间隙取在凹模上。
1）凸模宽度
Lp=(L +x Δ)−σp 0=(14+0.5x0.1)−0.020=14.05−0.020 mm
2)凹模宽度
Ld=(L +2C)0+σd =(14+2x1.76)0
+0.03=17.520+0.03 mm 2.5.3 模具圆角半径和凹模的深度的确定
（1）凸模圆角半径 一般来讲，凸模圆角半径等于或小于工件内侧的圆角半径：
R
= 0.5 mm
凸
(2) 凹模圆角半径凹模的圆角半径并不直接影响工件的尺寸，但太小是会在弯曲时擦伤毛坯，使材料表面出现划痕，太大回增加凹模深度。
凹模半径可查表2-4；
表2-4 凹模圆角半径与凹模深度对应关系
查表取：R
=8mm l=25 mm
凹
2.6确定模具总体结构
工件形状简单，2xΦ8可作弯曲时定位孔，定位销钉直径应根据凹模尺寸确定。
为了取件和压料，设置弹性顶件装置。
为了使顶板不产生横向窜动，顶板应与凹模滑配，并用弹簧产生压料力和顶件力。
（图2-5）
