Description
Technical Field
The utility model relates to the field of auxiliary devices on roll bending forming equipment, in particular to a guide device between passes for roll bending forming of a short experimental plate.
Background
Roll forming (commonly referred to as cold roll forming) is a process of plastic forming, in which a metal strip is passed through a plurality of forming rolls in a sequential arrangement to be bent and deformed in a pass-by-pass manner to produce a product having a predetermined cross-sectional shape. The pass interval refers to the horizontal distance between the roll axes of two adjacent passes in the arrangement direction of the rolls, namely the forming direction of the plate.
In the production process of roll bending related enterprises, the end of a plate is extracted from a steel coil, the plate enters from the first pass until the last pass is formed, and then the plate is cut off by a forming shear at the rear end of roll bending equipment to form a product, namely the plate is positioned in an upper roller and a lower roller of all passes at the same time in most of time.
The difference between a roll bending experiment in a laboratory and a roll bending related enterprise directly using a complete steel coil for forming is that in the roll bending forming experiment, in order to test the performance of a related device or research the forming mechanism of a plate, a large number of short experimental plates with the length smaller than the distance between adjacent passes are used, repeated forming tests are carried out on a certain pass of roll bending equipment, and a large number of experimental data are summarized, so that the roll bending equipment is improved or the roll bending equipment is used for researching the forming mechanism of the plate. Since the length of the experimental plate is smaller than the inter-pass interval, a special guide and limiting device is needed in the experimental plate forming process, otherwise, the advancing direction of the experimental plate during forming is difficult to control, and the experimental plate is poor in forming quality.
The following disadvantages are present if the guide of the inter-pass vertical rolls of a conventional roll bending plant is used for short sheet forming:
the shape of the guide wheel of the first and traditional vertical rolls between passes is designed according to the shapes of the plates of the front and the back passes at the position of the guide wheel, and the guide wheel has the function of auxiliary forming in the transition stage of forming of the front and the back rolls, so that the guide wheel can only be fixedly arranged between the two specific passes after the shape of the guide wheel is determined and cannot be changed freely.
Secondly, when a short plate is used for a roll bending experiment for a certain pass, if a traditional pass intermediate vertical roll is used as a guide, the effect is poor, and the traditional pass intermediate vertical roll only has a pair of guide wheels, so that the plate enters the roll, particularly the initial stage of the roll, and the horizontal direction rotation phenomenon is serious, and the horizontal direction rotation freedom degree of the plate cannot be limited by the pair of guide wheels, so that the experimental plate is poor in forming quality.
Third, the conventional roll stand between passes is relatively heavy, uses two sets of screw drives to adjust the lateral position of the two guide wheels, respectively, and the height of the guide wheels is not adjustable, and is not suitable for guiding flat sheet materials because the shape of the guide wheels is designed for the purpose of transition of sheet material forming between two passes.
In a roll bending forming experiment in a laboratory, in order to avoid waste of plates, short experimental plates with lengths smaller than the pass interval are usually used for the experiment, but a problem is caused, and a correction leading-in device special for the short plates is not provided, so that the situation that the plates are inclined or tilted easily occurs in actual operation, and the quality of the short experimental plates formed in the pass cannot reach the standard.

As a further preference of the utility model, the brackets and the limiting wheels are used in pairs, the vertical edges of the two brackets are screwed into the threaded holes on the side surfaces of the two memorial archways in a certain pass through the bracket fixing screws, and the transverse edges are used for supporting the limiting plates and are fixed through threaded connection; the limiting wheels are 4 in number and are installed on the grooves of the limiting plates, and the positions of the two groups of limiting wheels can be transversely adjusted to limit the rotational freedom degree of the short experimental plate in the horizontal direction, so that the plate only has the freedom degree along the forming direction.
As a further preferable mode of the utility model, the groove for placing the limiting wheel on the limiting plate is a long groove for adjusting the transverse position of the limiting wheel.
In a further preferred embodiment of the present invention, the stopper wheel is provided with a V-shaped groove, and the V-shaped groove allows the stopper wheel to adapt to different plate thicknesses.
In a further preferred embodiment of the present invention, the angle of the V-shaped groove is 35 ° to 50 °.
