Type system.
Background technology
The rolling power of cold-rolled forming section actually utilizes the friction between roller mold and strip steel
Power drives strip steel.At present, cold roll forming unit (seeing " roll-forming technology handbook ")
Power is provided, then by the Speed Ratio Distribution case of each sortie of connecting by one group or two groups of mair motor
Connect with corresponding axle, drive dress roll shaft topping roll mould roll-forming, in production in control
The roll line speed stating each sortie keeps consistent.But clod wash hat product made from steel difference in height compares
Greatly, in molding low spot and high point roll line speed inconsistent (size of each mould differs,
Diameter also differs), cause speed difference big, under the effect of frictional force, speed larger part,
It is easy for that scuffing or roll marks occur at belt steel surface.Along with the complexity of shape of product, bending
Circular arc is the most, and thickness is the biggest, and product the ratio of width to height is the biggest, required rolling in process of producing product
Power processed (power) is the biggest.(four bent angles synchronizations of cold-rolled forming section when using molding simultaneously
Distribution angle forming, as at two bent angles and bottom at the wing of hat steel two bent angles often
All change in a time (molding)), strip steel produces different merits on same section,

For driven roll.In order to ensure shaped steel linear velocity in forming process close to or as far as possible one
Cause, the B that reference point when calculating transmission speed ratio is chosen the most all in deformation position, i.e. Fig. 4
Put rather than C point.Owing to the distributor box speed ratio of LW600 unit determines that, therefore calculate speed
Than time, only accurately calculate the diameter of every sortie roll corresponding to Speed Ratio Distribution case.Example
As in the 4th sortie, B point strip steel is bent downwardly deformation, by downward bending power, therefore
The kind of drive selects upper transmission, and i.e. going up roller is drive roll, and lower roll is driven roll.Each sortie
Deformation is different, and optional main transformer shape roller is as drive roll.
When, after shaped steel molding to above-mentioned 5th molding milling train 5, linear differential starts to become by frame
Greatly, in order to avoid product surface scratches, Roller Design bigger for linear differential has been become axle
Runner.In forming process, bearing roller is a driven roll, i.e. ensure that the molding of strip steel,
Also ensure that synchronization with strip speed.

And the rotational angular velocity between the 3rd bottom roll mould 3.2 is than for 1.414:1;On described 4th
Rotational angular velocity between roller mold 4.1 and the 4th bottom roll mould 4.2 is than for 1.414:1;
Rotational angular velocity ratio between described 5th topping roll mould 5.1 and the 5th bottom roll mould 5.2
For 1:1;Rotation between described 6th topping roll mould 6.1 and the 6th bottom roll mould 6.2
Angular velocity is than for 1.8:1.In order to ensure that shaped steel linear velocity in forming process is close
Or the most consistent, the present invention devises above-mentioned transmission speed ratio and the kind of drive.
In technique scheme, in described 4th molding milling train 4, described hat steel wing
There is between 4th sortie rolling upper overturning 4.11 and hat steel 7 wing the molding visual angle of 3 degree
8.The present invention is reserved molding visual angle 8 on above-mentioned roll, reduces contacting of roll and strip steel,
Prevent the scuffing to belt steel surface further.
Strip steel the most all can have certain deformation to rebound, and applicant is pre-when designing mould
Certain bounce space, i.e. molding visual angle 8 are stayed, as shown in Figure 7.Regarded by reserved molding
Angle 8, reduces the contact surface of roll and strip steel, thus reduces upper roller or lower roll at deformation not
Necessary stress, also reduces strip steel linear differential at driven roll simultaneously.
The present invention is redesigning the mould structure of each sortie, redesigns in every sortie
Roller and the speed ratio of lower roll, become bearing roller by Roller Design bigger for linear differential, and reserve
After forming angle, cap steel is trial-produceed successfully smoothly at LW600 unit.Unit operation is stable, not
Occur that Speed Ratio Distribution case damages, disconnected universal joint phenomenon.Product quality has reached correlation technique mark
Accurate requirement, presentation quality is preferable, and scratching does not occurs in surface.
The content that this specification is not described in detail belongs to known to professional and technical personnel in the field
Prior art.
