A manual connecting rod shears, which involves a manual connecting rod type shearing machine, especially a manual connecting rod shears for cutting the thickness of the metal plate from 0.1mm to 1mm, and the thickness of the shear non metal plate from 0.5mm to 4mm. In order to solve the inconvenience of cutting the thin plate in the course of the existing integrated fitter, the thin plate is wasted, the cutting tool is easily injured by the improper use of the cutting tool, and the existing shearing machine is not suitable for the problems used in the students' teaching. The lower machine plate is fixed to the base plate, the lower blade is fixed to the lower board and the second fixed arm is fixed to the upper board. The first fixed arm is fixed with the second fixed arm, the upper blade is set on the upper machine plate, the upper blade is fitted with the lower blade, the upper plate connection arm is set at one end of the press bar, the upper plate connection arm is fixed with the press rod, the upper plate connection arm is connected with the upper board, the upper blade is connected with the connecting rod, the connecting rod is connected with the press rod, and the connecting rod is connected with the press rod, and the connecting rod is connected with the press rod. The blade is connected with the upper board. One

手动连杆式剪板机
本专利技术涉及一种手动连杆式剪板机,尤其涉及用于剪切金属板厚度为0.1mm至1mm,剪切非金属板厚度为0.5mm至4mm的手动连杆式剪板机。
技术介绍
薄板的很多死角和外弯处难以加工,而且材料浪费较多,锯条耗损大。用铁皮剪子下料时,力量小的学生剪不动,而且剪断时剪切惯性还容易夹伤手。而且现有的手动剪板机的压杆传动部件是由多个杆机构组成的,结构复杂,制造不便,并且现有的手动剪板机体积大,不适于一体化钳工制作的课程中使用。
技术实现思路
本专利技术的目的是提供小型手动连杆式剪板机。本专利技术为解决上述问题采取的技术方案是:本专利技术的所述手动连杆式剪板机包括底座板与压杆,所述手动连杆式剪板机还包括下机板、上机板、下刀片、上刀片及连杆,底座板水平放置,下机板竖直固接于底座板的顶面,下机板设有第一固定臂,第一固定臂固接于下机板左端顶面,下刀片竖直固接于下机板右端顶部,上机板设有第二固定臂,第二固定臂固接于上机板左端底面,第一固定臂与第二固定臂通过螺纹连接件相固接,上刀片竖直设置于上机板右端底部,上刀片与下刀片侧面贴合设置,压杆一端设有上机板连接臂,上机板连接臂的一端与压杆所述一端相固接,上机板连接臂的另一端与上机板右端顶部转动连接,上刀片的右端与连杆的一端转动连接,连杆的另一端与压杆所述一端转动连接,上刀片的左端与上机板转动连接,压杆另一端设有握把。本专利技术与现有技术相比具有以下有益效果:1、本专利技术的剪板机为单人操作,剪板灵活、剪切力强、体积小、重量轻、便于携带、不受环境和场地限制。2、上刀片05、连杆07、上机板连接臂61以及上机板03构成双 ...
