摘　　要：上压梁的弯曲变形将影响接长条的质量,因此生产中就要求接长机的上压梁能够减少弯曲变形.上压梁的弯曲变形量(挠度)与压力F的作用点位置,也就是上压气缸(或油缸)在上压梁上安装点的位置密切相关.本文通过优化上压气缸(或油缸)在上压梁上安装(支撑)点位置的方法,可以最大程度地减少上压梁的弯曲变形量.the bending deformation of the upper pressure beam will affect the quality of the connecting strip,so it is required to reduce the bending deformation of the upper pressure beam of the connecting machine in the production. The bending deformation(deflection)of the upper pressure beam is closely related to the position of the operating point of pressure F,that is,the position of the upper pressure cylinder(or oil cylinder)on the upper pressure beam. In this paper,by optimizing the position of the upper pressure cylinder(or oil cylinder)on the upper pressure beam,the bending deformation of the upper pressure beam can be minimized.
