Description

用于金属壳体的无费屑刮削机构
技术领域
本发明涉及智能手写笔领域,尤其涉及一种用于金属壳体的无费屑刮削机构。
背景技术
随着移动通信技术的发展,触摸屏式便携式电子装置越来越受使用者的喜爱。现有市场上的触摸屏式便携式电子装置通常采用附带的手写笔进行信息的输入操作。
现有的电子装置配有的手写笔为了方便携带、不易丢失,都是内置于电子装置内部,需要使用手写笔时将其从电子装置中抽出。而电子装置内部元件较多,装配空间有限,内置手写笔占据一定的空间,而且,内置的手写笔尺寸较小,使用不便。现有智能手写笔金属壳体大部分是采用塑料制成,塑料手机壳耐磨性差,使用一段时间后会出现划痕,甚至掉色等状况。为此,需采用金属壳体,例如采用不锈钢、铝合金或钛合金壳体,这些金属壳由于耐磨性好,而且可以做出精美的外观,很受消费者喜欢。但是现有的智能手写笔金属壳体受加工方法的限制,成本居高不下,难以普遍使用。由于需要安装其他零部件,需要设计很多扣位、柱位、西弧角、高低台阶等等,如果用整块材料切削制作的话,如果需要在数控机床加工中心加工则时间很长,成本高,导致最终产品极其昂贵。
发明内容
本发明提供一种用于金属壳体的无费屑刮削机构,此无费屑刮削机构操作简单,可以减少人工,同时降低了报废率,相应降低了生产成本,降低了投资成本,设备成本低,维修成本低,且推刀复位时无费屑,也避免了对工件的损伤。
为达到上述目的,本发明采用的技术方案是:一种用于金属壳体的无费屑刮削机构,包括由上往下依次设置的上模夹板、止挡板、脱料板和下模座,所述上模夹板下表面具有一竖直斜楔和弹性件,所述止挡板具有一传力杆、供竖直斜楔嵌入的通孔且下表面具有一竖直斜面滑块,脱料板具有一强压块和2个通孔,所述下模座和脱料板之间安装有可沿水平方向运动的冲刀,此冲刀的后端具有一水平斜面滑块,所述脱料板中一个通孔供上模夹板的竖直斜楔嵌入,另一通孔供止挡板的竖直斜面滑块嵌入;
一安装板固定于所述脱料板或者下模座上,一弹簧套装于推杆上并位于其安装块与安装板之间,此推杆的前端和后端分别为安装块、挡块,此推杆的安装块另一端固定有一水平斜楔和顶杆,所述顶杆与冲刀的前端接触,所述水平斜楔与止挡板的竖直斜面滑块配合;
所述传力杆位于弹性件和强压块之间,所述脱料板和下模座之间具有漏料孔且脱料板具有一位于漏料孔上方的吹废通孔,一进气嘴位于脱料板的侧端面,此进气嘴与吹废通孔之间通过通道贯通;所述上模夹板和脱料板各自的同侧端之间通过一对挂孔和连接链连接;
所述摩擦片通过螺栓固定于下模座;所述下模座上表面安装有一摩擦片。
由于上述技术方案运用,本发明与现有技术相比具有下列优点:
1、本发明用于金属壳体的无费屑刮削机构,其操作简单,可以减少人工,同时降低了报废率,相应降低了生产成本,降低了投资成本,设备成本低,维修成本低,降低了投资成本,又降低切削加工的加工量,将加工时间最高可减少95%,极大的降低了金属手机壳的成本;其次,当上模夹板下行时,竖直斜楔推动水平斜面滑块,从而驱动冲刀水平前行,同时竖直斜面滑块下行推动水平斜楔,当其推力大于弹簧张力时推杆压缩弹簧,且强压块定位工件后,冲刀对待加工件进行刮削操作,完成后,上模夹板上行,在弹簧的推力下,推杆的顶杆和水平斜楔分别推动冲刀自动复位和推动止挡板上行,此时强压块对待加工件的压力几乎为零,推刀复位时无费屑,也避免了对工件的损伤。
2、本发明用于金属壳体的无费屑刮削机构,其传力杆位于弹性件和强压块之间,脱料板和下模座之间具有漏料孔且脱料板具有一位于漏料孔上方的吹废通孔,一进气嘴位于脱料板的侧端面,此进气嘴与吹废通孔之间通过通道贯通,当冲刀对工件刮削操作后,可通过从进气嘴通气体,从而实现将刮削产生的费屑吹下漏料孔,避免了在弹簧的推力下,推杆的顶杆推动冲刀自动复位时,费屑对产品的刮伤;其次,其上模夹板和脱料板各自的同侧端之间通过一对挂孔和连接链连接,上模夹板上行时便于调整高度,从而带动脱料板上行,方便安装工件和脱模。
