Abstract

本实用新型涉及一种V型纸护角冲裁压痕机,包括机身、固定于机身的凹模和设在冲头固定板上的冲头,该冲头为等腰三角形,凹模远离机身的一侧对应设置有型配的凹槽,该凹槽离机身最远的顶端开有竖缝,对应该竖缝还设置有压痕用的压块,该压块通过弹簧连在凹模侧壁,所述冲头固定板上对应设置有推压该压块的推块。本实用新型可一次即将板料冲裁、压痕,操作简便,生产效率高。

Description

V型纸护角冲裁压痕机
技术领域
[0001] 本实用新型涉及护角加工领域,尤其涉及一种纸护角加工装置。 背景技术
[0002] 护角是用来防止物品表面直接与其它对象接触或碰擦而刮伤的工具,其中,纸护角因轻便、易回收而应用广泛。纸护角又名纸包角或护角纸板,由牛皮纸经冲裁、弯折而成, 多为V型,目前的加工装置通常只是在牛皮纸的一面冲裁出一个三角缺口,然后直接将纸沿三角口弯折成V型,问题是:有些牛皮纸材料较硬,手工弯折费力且精度不高,用机器弯折又显繁琐,也有人在冲裁后另采用专门的刀具压痕,最后再人工弯折,这依然显得繁琐, 生产效率不高。
发明内容
[0003] 本实用新型解决的技术问题是,提供了一种V型纸护角冲裁压痕机,可一次即将板料冲裁、压痕,操作简便,生产效率高。
[0004] 本实用新型采用的技术方案为:
[0005] 一种V型纸护角冲裁压痕机,包括机身、固定于机身的凹模和设在冲头固定板上的冲头,该冲头为等腰三角形,凹模远离机身的一侧对应设置有型配的凹槽,该凹槽离机身最远的顶端开有竖缝,对应该竖缝还设置有压痕用的压块,该压块通过弹簧连在凹模侧壁, 所述冲头固定板上对应设置有推压该压块的推块。
[0006] 进一步,所述压块外平行设置有保护块。
[0007] 进一步,所述保护块为矩形,所述推块为梯形。
[0008] 本实用新型的有益效果为:
[0009] 本实用新型通过在冲头固定板增设推块,在凹模侧壁增设压块,可一次即将板料冲裁、压痕,操作简便,生产效率高。
附图说明
[0010] 图1为本实用新型沿中心线的纵剖图。
[0011] 图2为本实用新型凹模的平面示意图。
具体实施方式
[0012] 下面结合附图和实施例对本实用新型作进一步说明。
[0013] 实施例:
[0014] 如附图所示,V型纸护角冲裁压痕机,包括机身1、固定于机身的凹模5和设在冲头固定板2上的冲头3,该冲头3为等腰三角形,凹模5远离机身1的一侧对应设置有型配的凹槽9,该凹槽9整体呈等腰三角形,凹槽9离机身1最远的顶端开有竖缝10,对应该竖缝 10还设置有压痕用的压块7,该压块7通过弹簧6连在凹模5侧壁,如图1,凹模5侧壁上可开一盲槽,弹簧6端部可嵌入盲槽,所述冲头固定板2上对应设置有推压该压块7的推块 4。
[0015] 进一步,所述压块7外平行设置有保护块8,防止压块直接受推块挤压易变形、磨损、降低精确度等却不易更换。
[0016] 进一步,所述保护块8为矩形,所述推块4为梯形,当然,二者的形状也可对调,或采用其他形状,只要保证4下压时能将压块7推压至紧贴凹模。
[0017] 使用时,L形板料的一条臂紧贴凹模的上表面,另一条臂紧贴凹模的侧面,开动机器,冲头固定板下移,带动冲头和推块同时下移,冲头先将板冲裁,然后冲头继续下移,同时,推块推动保护块,保护块推压压块至紧贴凹模,冲头的棱与压块共同挤压板料,冲头沿竖缝在板料上压出压痕,板料沿压痕弯折即成V型纸护角。冲头回位后,弹簧亦回位并将压块推开。
