Embodiment Construction

[0022] Below in conjunction with the description of the accompanying drawings, the numerical simulation method of the cutting process of the strip cutter of the present invention is further described:

[0023] The first step is to establish and import the model: use Pro / E software to establish the 3D solid model of steel wire and mud strip, save the model as a file in IGES format, and then import it into LS-DYNA respectively, in which the 3D solid model of steel wire and mud strip is cut Models are based on drawings.

[0024] The second step is to set the material properties: a reasonable material model is the fundamental guarantee for the success of the numerical simulation. The mud strip cutting tool is carbon spring steel wire, and its base material is C36D2. In order to reduce the simulation time, and consider the expected simulation The data are cutting force and cutting power consumption. The rigid body material model Rigid Material is selected, and the material paramete...

Abstract

The invention relates to a numerical simulation method for a cutting process of a bar cutter. The method comprises following steps: establishing a simulation model, and simulating the cutting process of the bar cutter through the ANSYS / LS-DYNA software; analyzing an influence rule for the cutting process by angle factors, and determining cutting angle factor level values; changing the speed, diameter and cutting angle of a cutting steel wire, and performing dynamics simulation analysis on a moving process when the steel wire cuts clay strips; and designing a orthogonal test, analyzing important orders of the factors influencing the cutting power consumption and steel wire maximum equivalent stress, and finally obtaining an optimal combination of working parameters of the bar cutter. The method is advantageous in that the method can simulate actual working conditions of the bar cutter and can provide the basis for the selection of the working parameters of the bar cutter, and therefore the power consumption and production cost of the bar cutter can be reduced, the working efficiency of the bar cutter can be improved, and the qualified rate of adobe can be increased.

Description

technical field [0001] The invention relates to the field of adobe manufacturing, in particular to a numerical simulation method for the cutting process of a strip cutter. Background technique [0002] The strip cutting machine is an important equipment for brick forming. The main failure mode of the cutting steel wire of the strip cutting machine is fracture when cutting the mud strip. On the one hand, the fracture is caused by the friction between the steel wire and the mud strip for a long time; When it reaches hard small particles, it breaks suddenly. The cutting machine needs to stop the operation of the entire brick making system when the steel wire breaks, and then manually replace the broken blank cutting steel wire. This not only greatly reduces the working efficiency of the slitting machine, but also wastes the electric energy consumed by the motor idling. [0003] Therefore, by simulating the cutting process of the strip cutting machine, we hope to analyze and m...
