Strength Of Continuous Extrusion Machine Connected Components Analysis

Continuous extrusion machine bolts connect the base and frame, When the the continuous extrusion machine work, it plays the role of the fixed frame, For continuous extrusion machines work and safety of great significance. Works calculated using the traditional analog design experience, for reliability purposes, too large safety factor was chosen, so it is necessary to analyze bolt of the stress state and optimization through simulation results.In this paper, using finite element software ANSYS modeling methods to establish the rack, bolts and the base model, select the appropriate software modules and mesh generation finite element model, the base and the frame plate is set to friction contact, between the bolts and the base, the bolts and the rack is set to the frictional contact to finite element simulation, reached the base, frame and bolts of the stress distribution, carried out on the bolt strength check to verify the work of continuous extrusion machine stability and security.In order to verify the correctness of simulation results, using the dynamic stress-strain experiment DH-5920 dynamic signal measurement and analysis system, collecting the stress of the continuous extrusion machine bolts and the right side of base plate, analyzed the test results and finite element simulation results are in good agreement.Based on the simulation analysis, proposed TLJ400 continuous extrusion machine of the nose section of the improvement program, making the right of the compression part of the plate continuous extrusion machine longer, remove the internal oblique tendon extruder plate and the left tendon plate, increase the reinforcement plate the right side of extrusion machine, by finite element techniques to improve its structure, so that the nose section of the improved stress distribution more uniform deformation smaller, structure is more reasonable for the continuous extrusion machine design of future reference.
