Roll forming is that the metal plate and belts such as coiled material, band are passed through the multi-step forming roll that is arranged in order so as to constantly
Ground carries out transverse curvature, to make the section bar of specific section.This sheet material forming technology, compared with hot-rolled steel section, has efficient, section
Can, section material, advanced and applicable the advantages of, have a very wide range of applications in all trades and professions such as building, traffic, machinery, household electrical appliances.
At present, Chinese national economy sustained and rapid development, the roll bending section bar market demand increases increasingly, and range of application constantly expands
Greatly, market prospects are very wide.Under normal circumstances, during roll bending formation, sheet material only produces transversely deforming and does not produce longitudinal direction
Deformation, therefore, the horizontal bending strength of section bar compare relatively low, particularly web size relative to floor size than larger when, its
Transverse bending strength is lower.Using embossing roll, molding horizontal embossing at section bar web can be that the problems referred to above obtain
Solve.But, very big noise can be produced in press grain forming, excessive noise can cause working environment to deteriorate, and affects workman
Healthy.Reduce noise using the method adding a cover blimp in actual production, but preferable noise abatement effect can not be reached
Really.
Content of the invention
It is an object of the invention to provide a kind of embossing technique noise reducing method and its device are to reduce in embossing process engineering
The noise producing because of shock and the embossing resilience of embossing roll and sheet material.
The present invention is solved its technical problem and is realized by following technical proposals：
A kind of embossing technique noise reducing method is it is characterised in that first when embossing roll engagement, emboss roll tooth and sheet material
The impact endurance test shock that engagement can produce forms first noise source, and the elastic strip being embedded in embossing roll between cog can be made an uproar closest
The position of source of sound absorbs the produced part of this noise source and shakes.Then, when embossing roll is disengaged, the rebound velocity of embossing
Lag behind the translational speed of embossing roll tooth and produce backlash bullet and form second noise source, when embossing resilience, elastic strip energy
Enough being close to the side embossing, thus reducing the vibrations producing during embossing resilience, fundamentally reducing the generation of noise.Finally, exist
The vibrations producing at two noise sources can be propagated along sheet material to surrounding and are gradually converted into airborne noise in the process, pressure
The flexible conveyor belt of line roll both sides is close to the both sides of the sheet material frequency to reduce vibrations, thus reducing the mesh of noise
's.
A kind of embossing technique noise-decreasing device realized according to said method, including roll forming mechanism, embossing noise-decreasing device
Deng it is characterized in that, described roll-forming machine include uncoiler, strip level(l)ing machine, stock guide, roll forming roll stacks,
Finished roll, shearing device, discharge pedestal；Described embossing noise reduction mechanism includes embossing roll, elastic strip, flexible conveyor belt, is located at
Before finished roll after roll forming roll stacks.
Described embossing noise-decreasing device is made up of embossing roll and flexible conveyor belt.The profile of tooth of embossing roll is special setting
Meter, each two embossing roll between cog is all embedded with elastic strip, and the diameter of embossing roll and length can be according to different processing section bars
With technological requirement and change, embossing roll tooth proportions can be changed according to different embossing techniques.The length of embossing roll
Web width depending on processed section bar.Depending on the quantity of embossing roll can be according to concrete processing section bar.Each embosses roll
Before and after be designed with flexible conveyor belt, flexible conveyor belt is close to plate surface, and its linear velocity and sheet material are synchronous, the length of elastic webbing
Degree can be adjusted in the range of 80mm-1000mm according to specific process conditions.Its width can be according to the abdomen of concrete section bar
Depending on plate width.Depending on the quantity of conveyer belt can be according to concrete processing section bar.
The present invention has technique effect beneficial as follows：
1st, the present invention takes many kinds of measures to reduce noise in terms of noise source and route of transmission two, more can reach expected
Effect；
2nd, the present invention improves the quality of Embosser, reasonable in design, and device structure is simple, and easy to operate, noise reduction effect is bright
Aobvious.
