Description
技术领域
[0001]本发明涉及模具领域，具体是一种齿圈模具。
背景技术
[0002]模具，在外力作用下使坯料成为有特定形状和尺寸的制件的工具。
[0003]广泛用于冲裁、成形冲压、模锻、冷镦、挤压、粉末冶金件压制、压力铸造，以及工程塑料、橡胶、陶瓷等制品的压塑或注塑的成形加工中。模具具有特定的轮廓或内腔形状，应用具有刃口的轮廓形状可以使坯料按轮廓线形状发生分离(冲裁)。应用内腔形状可使坯料获得相应的立体形状。
[0004]模具一般包括动模和定模(或凸模和凹模)两个部分，二者可分可合。分开时装入坯料或取出制件，合拢时使制件与坯料分离或成形。模具是精密工具，形状复杂，承受坯料的胀力，对结构强度、刚度、表面硬度、表面粗糙度和加工精度都有较高要求，模具生产的发展水平是机械制造水平的重要标志之一，模具种类很多，根据加工对象和加工工艺可分为:①加工金属的模具。包括冲压模(如冲裁模、弯曲模、拉深模、翻孔模、缩孔模、起伏模、胀形模、整形模等)、锻模(如模锻模、镦锻模等)以及挤压模和压铸模等。②加工非金属和粉末冶金的模具。包括塑料模(如注射模、压塑模和挤塑模等)、橡胶模和粉末冶金模等。根据结构特点，模具又可分为平面的冲裁模和具有空间的型腔模。模具一般为单件，小批生产。模具除其本身外，还需要模座、模架、导向装置和制件顶出装置等，这些部件一般都制成通用型。治具是一个木工、铁工、钳工、机械、电控以及其他一些手工艺品的大类工具，主要是作为协助控制位置或动作(或两者)的一种工具。因台湾曾被日本曾长期统治，也就习惯了“治具”这个词。
[0005]治具在工业时代前就已被广泛使用，包括机械治具、木工治具、焊接治具、珠宝治具以及其他领域。某些类型的治具也称为“模具”或“辅具”，其主要目的是为重复性和准确的重复某部分的重制。一个明显的例子是当复制钥匙时，原始的钥匙通常被固定于治具上，如此机器就能借由原始钥匙外观的导引复制出新的钥匙。
[0006]按所成型的材料的不同，模具可分为金属模具和非金属模具。
[0007]金属模具又分为:铸造模具(有色金属压铸，钢铁铸造)、冲压模具和锻造模具等；非金属模具也分为:塑料模具和无机非金属模具。而按照模具本身材料的不同，模具可分为:砂型模具，金属模具，真空模具，石蜡模具等等。其中，随着高分子塑料的快速发展，塑料模具与人们的生活密切相关。塑料模具一般可分为:注射成型模具，挤塑成型模具，气辅成型模具等等。大规模生产的非钣金钢件一一冷镦、模锻、金属模等。钣金出料一一热乳、冷车U热卷、冷卷钣金加工一一拉深、整型、折弯，冲孔，落料有色金属一一压铸，粉末冶金塑料件一一注塑、吹塑(塑料瓶)，挤塑(管件)模具其他分类:合金模具、钣金模具、塑料模具、冲压模具、橡胶模具，铸造模具、锻造模具、挤出模具、压铸模具、汽车模具、滚丝模具.
[0008]有许多治具之所以产生是因为商业的需要，因为有许多类型的治具是定制化的，大多是为了提高生产力、重复特定动作、或使工作更加精确。类似的治具可能会因为使用于不同的时间和地点。
[0009]批量生产一个产品，设计并制造一种合适的模具对于提高生产效率，节约生产成本意义重大。目前还没有一种专门用于生产传动齿圈的专用模具。
发明内容
[0010]本发明正是以上技术问题，提供一种专门用于生产传动齿圈的专用模具。
[0011]本发明通过以下技术方案实现:
[0012] —种齿圈模具，包括成形上一冲、成形上二冲、成形中模、成形下冲、成形芯棒，其特征在于成形上二冲套在成形上一冲外，成形上二冲、成形上一冲位于上部，成形中模位于下部，成形下冲套在成形芯棒外，套有成形下冲的成形芯棒穿过成形中模与上部的成形上二冲、成形上一冲对应。
附图说明
[0013]附图图1是本发明的剖视图，其中:
[0014] 卜成形上一冲，2-成形上二冲，3-成形中模，4-成形下冲，5-成形芯棒。
具体实施方式
[0015]下面结合具体实施例对本发明做进一步说明。
[0016] —种齿圈模具，包括成形上一冲1、成形上二冲2、成形中模3、成形下冲4、成形芯棒5，其特征在于成形上二冲2套在成形上一冲I外，成形上二冲2、成形上一冲I位于上部，成形中模3位于下部，成形下冲4套在成形芯棒5外，套有成形下冲4的成形芯棒5穿过成形中模3与上部的成形上二冲2、成形上一冲I对应。
[0017]使用时，先将成形上一冲I套在成形上二冲2里，然后安装在冲床上部，再将成形中模3固定，再依次安装成形下冲4、成形芯棒5，然后放入传动齿圈压坏，启动机器，即可一次冲压出传动齿圈。
[0018]本发明可通过一次冲压成形半伞齿轮，结构简单，使用方便。
