Description

Bend pipe function tool structure based on veneer reeling machine

Technical field

This utility model belongs to veneer reeling machine technical field, particularly relates to a kind of bend pipe function based on veneer reeling machine Tool structure.

Background technology

Veneer reeling machine is the moulding lathe that sheet material carries out continuity point bending, has the O type that rolls, U-shaped, multistage R etc. The function of difformity sheet material.On symmetric plate bending machine, roller is in two lower roll central symmetry positions are by hydraulic cylinder Hydraulic oil act on piston and make vertical displacement movement, drive two lower roll teeth by the final-stage gear of main gear reducer Wheel engagement rotates, and provides moment of torsion for rolling sheet material.The smooth plastic metal plate of veneer reeling machine specification passes through Between three working rolls (two lower rolls, upper rollers) of veneer reeling machine, by pressure and the rotation of lower roll down of upper roller Transhipment is dynamic, and (internal layer compression, middle level is constant, and outer layer stretches through multi-pass continuous bend to make metallic plate Deformation), produce permanent plastic deformation, roll into required cylinder, cone cylinder or their part. This hydraulic three-roller plate roll shortcoming is that sheet material end need to carry out pre-bending by miscellaneous equipment.This veneer reeling machine is suitable for In roll bending thickness at the large-scale veneer reeling machine of more than 50mm, two lower roll bottoms add a row and fix carrying roller, shorten Two lower roll spans, thus improve and roll workpiece accuracy and machine overall performance.

The side of repair welding again is bent after producing the clerestory frame square tube bending artificial baking hot bending of general employing or otch Formula produces.Production efficiency is low, wastes pneumoelectric, and consumables cost is high.Bend square tube need 30 minutes complete Become, and molding is bad, is easily generated substandard products.

Therefore, this utility model provides a kind of bend pipe function tool structure based on veneer reeling machine, and frock is with original Based on old veneer reeling machine, on original upper roller of press brake wheel, increase pressure ring is as auxiliary clamp, adjusts pinch roller Dynamics, to the success of required bending square tube single use deflectable.Every bend pipe required time just can be complete less than one minute Becoming, beautiful appearance, quality can reach to design requirement, will not produce substandard products.The use of this frock, expands The range of work of plant equipment.Production efficiency promotes at double, reduces production consumptive material.
