Abstract

一种刀模，包括刀具主体（1），刀具主体（1）的冲切面上设有方形的冲切区域（2），冲切区域（2）的一条边缘设有锯齿形刀刃（21），该锯齿形刀刃（21）的刃口凸出于冲切区域（2）的表平面，锯齿形刀刃（21）设置在冲切区域（2）长度方向的边缘处，冲切区域（2）的另外三条边缘设有压条，冲切区域（2）内设有多个图案框（22），图案框（22）的边缘设置为平刀刃，该平刀刃的刃口凸出于冲切区域（2）的表平面。本刀模能够提高原材料的利用率。

Description

刀模 技术领域
本发明涉及胶带冲切技术领域，特别涉及一种刀模。
背景技术
目前，用于冲切胶带类产品的方形刀模冲切出的产品存在以下问题：1、产品的两侧边各保留着10mm左右的多余区域；2、相邻产品之间存在着2-5mm的间距区域。上述的多余区域和间距区域都造成了原材料的浪费，致使原材料的利用率较低。
发明内容
基于此，本发明的目的在于克服现有技术的缺陷，提供一种能够有效提高原材料的利用率的刀模。
其技术方案如下：
一种刀模，包括刀具主体，刀具主体的冲切面上设有方形的冲切区域，冲切区域的一条边缘设有锯齿形刀刃，该锯齿形刀刃的刃口凸出于冲切区域的表平面。
在其中一个实施例中，所述锯齿形刀刃设置在所述冲切区域长度方向的边缘处。
在其中一个实施例中，所述锯齿形刀刃的长度与所述冲切区域的长度相同。
在其中一个实施例中，所述冲切区域的另外三条边缘设有压条。
在其中一个实施例中，所述冲切区域内设有多个图案框，图案框的边缘设置为平刀刃，该平刀刃的刃口凸出于所述冲切区域的表平面。
在其中一个实施例中，所述刀具主体为钢板或合金板。
下面对前述技术方案的优点或原理进行说明：
上述的刀模中，冲切区域与产品的外形相适配，在原材料上冲切一次便制作出一个产品，相邻两个产品的连接线是由锯齿形刀刃冲切形成的间隔点线，用于保障多个产品彼此不断开、连接有序，当需要分开时，只需从间隔点线撕开即可。可见，通过本刀模冲切出的产品，其两侧边不会存在多余区域，相邻之间也不会存在间隔区域，因此，本刀模能够有效提高原材料的利用率。
附图说明
图1为本发明实施例所述的刀模的结构示意图；
图2为本发明实施例所述的刀模冲切出的产品的示意图。
附图标记说明：
1、刀具主体，2、冲切区域，21、锯齿形刀刃，22、图案框，3、原材料，31、产品，32、间隔点线。
具体实施方式
下面对本发明的实施例进行详细说明：
如图1所示，为一种刀模，它包括刀具主体1，刀具主体1的冲切面上设有方形的冲切区域2，冲切区域2长度方向的边缘处设有锯齿形刀刃21，锯齿形刀刃21与冲切区域2的表平面垂直，且该锯齿形刀刃21的刃口凸出于冲切区域2的表平面。其中，冲切区域2与产品的外形相适配，再如图2所示，在原材料3上冲切一次便制作出一个产品31，相邻两个产品31的连接线是由锯齿形刀刃21冲切形成的间隔点线32，间隔点线32用于保障多个产品31彼此不断开、连接有序，当需要分开时，只需从间隔点线32撕开即可。可见，通过本刀模冲切出的产品，其两侧边不会存在多余区域，相邻之间也不会存在间隔区域，因此，本刀模能够有效提高原材料的利用率。
本实施例中，锯齿形刀刃21的长度与冲切区域2的长度相同。冲切区域2的另外三条边缘设有压条，用于压平或保护原材料。冲切区域2内设有多个 图案框22，图案框22的边缘设置为平刀刃，该平刀刃的刃口凸出于冲切区域2的表平面，用于冲切形成产品上的图案。另外，刀具主体1为钢板或合金板。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
