Description

The online roll bending device that is used for the cold-rolled forming section milling train

Technical field

The utility model relates to a kind of cold-rolled forming section process equipment, particularly relates to a kind of online roll bending device that is used for the cold-rolled forming section milling train.

Background technology

The cold-rolled forming section product that automobile industry is used often need become shape bending certain radian, and method commonly used at present is at first to roll out vertical profile earlier by the cold-rolled forming section milling train, and then uses stretch benders to carry out secondary operations, and shape bending is become to specify radian.But there is certain defective in this process, mainly comprises: the die cost height that 1. needs, make and adjustment cycle long (1～3 day).Because this mould must guarantee section bar integral body is carried out bending, so die size is bigger, reaches 550mm * 200mm * 60mm usually, manufacturing expense height once, bending springback is difficult to control, the use of could finalizing the design after need repeatedly repairing a die in the process.2. mould and radian are single correspondences, if produce the product of other radians, need to increase new mould.3. utilization ratio of raw materials is low, considers the clamping position size of stretch benders and the straightway that there is a segment distance at section bar two ends, crooked back, and lumber recovery is lower, and the lumber recovery of this operation is about 85% usually.As seen, present processing method and equipment processing cost when the cold-rolled forming section product being bent to the appointment radian are higher.

The utility model content

Technical problem to be solved in the utility model is to solve the cold-rolled forming section product to bend to processing cost problem of higher when specifying radian.

The specific embodiment

The utility model is arranged on the output of cold-rolled forming section milling train, carries out the roll bending operation when raw material directly enters the utility model after the moulding of cold-rolled forming section milling train, and it is bent to the radian of appointment.Used for reference traditional roll bending technology, when the upright position of having fixed three roll bending rollers and horizontal level, section bar can only advance according to the formed circular arc in point of contact of section bar and three bending rolls, obtains needed radian thereby force section bar to occur bending and deformation.If want to change radian, the horizontal level of adjusting the roll bending roller then can.But it is exactly when handling the section bar of asymmetric section that this bending process has individual shortcoming, can lateral bending take place owing to the uneven distribution of the crooked modification stress of each point on the section bar cross section in bending, and this all is unacceptable for all products.The utility model is by being provided with upper and lower roll to avoid above-mentioned shortcoming.

Below in conjunction with accompanying drawing the utility model is made detailed explanation.As shown in Figure 1, the utility model comprises three roll bending roller assemblies 2 that distribute along arc, 3 and 4, the roll bending roller assembly comprises a left side, right supporting seat and last,

lower roll

21,22, a described left side, right supporting seat relatively is fixed on the frame of cold-rolled forming section milling train respectively, on,

lower roll

21,22 rotate respectively and are arranged on the described supporting seat, wherein go up,

lower roll

21,22 be oppositely arranged respectively and the cross-sectional shape of gap between the two and shaped steel suitable, section bar 1 passes roll bending roller assembly 2, on in 3 and 4, advance in gap between the lower roll, and lateral bending or the conical camber utilizing this gap to proofread and correct to take place in the section bar BENDING PROCESS, by independent adjustment roll

bending roller assembly

2,3 and 4 upright position, section bar 1 can be forced to bend to the radian of appointment, and has very big adjusting range, can realize the linearity adjustment of R1000～R8000, when changing the section bar kind, only need replace with, lower roll, the horizontal level of adjusting three roll bending roller assemblies gets final product, greatly reduce die cost and adjustment cycle (about 1 hour), simultaneously owing to be the on-line continuous bending, the utilization rate of section bar improves greatly, and lumber recovery has reached more than 97%.

Again in conjunction with Fig. 2, Fig. 3 and Fig. 4, a left side, right supporting seat comprises gripper shoe 23 respectively, adjust piece 25, pressing plate 31 and adjustment screw rod 30, gripper shoe 23 is provided with, the lateral surface of following two through holes and this gripper shoe 23 is provided with turning cylinder, on,

lower roll

21,22 roll shaft be inserted into respectively in the through hole on the gripper shoe 23 and and described through-hole wall between be provided with rolling bearing 24, be processed with a rectangular longitudinal fluting on the support 100 of cold-rolled forming section milling train output, adjusting piece 25 is arranged in this groove, adjustment screw rod 30 passes pressing plate 31 and is fixed on the adjustment piece 25, wherein adjust screw rod 30 and pressing plate 31 threaded engagement, pressing plate 31 is fixed on the support 100 of clod wash milling train output, when screw rod 30 was adjusted in rotation, this adjustment screw rod 30 drove adjustment piece 25 and moves up and down in groove.Adjust on the piece 25 and be embedded with rolling bearing 26, gripper shoe 23 lateral surfaces are provided with turning cylinder 27, and this turning cylinder 27 is inserted in this rolling bearing 26, and when screw rod 30 was adjusted in rotation, roller assembly moved up and down thereby adjustment piece 25 moves up and down the drive roll bending like this.

In BENDING PROCESS, upper and

lower roll

21,22 can rotate separately, thereby guarantees that the friction with section bar 1 is rolling friction, has protected section bar 1 surface, and the roll bending roller assembly moving axis 27 that can rotate rotates, thereby has realized the automatic angle adjustment of roll bending roller assembly.If the angle at BENDING PROCESS central roll roller assembly can not rotate, gap length between the upper and lower roll, size (on the vertical direction) will change so, do not realize the calibration function in the bending, and can form multi-point bending, cause the inhomogeneous of crooked radian, intention of the present utility model is exactly the frictional force of utilizing between section bar and the upper and lower roll, the roll bending roller assembly is rotated, guarantee that the circle center line connecting of upper and lower roll in the roll bending roller assembly is intersected in the center of circle of section bar circular arc all the time.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
