Description

Technical Field

[0001] The present invention relates to the technical field of longitudinal beam processing, and in particular to a longitudinal beam wing surface bending device. Background Art

[0002] During the production of automotive longitudinal beams, one of the steps is bending the longitudinal beam surface. However, during the forming process, the steel can rebound, resulting in substandard workpieces and resulting in scrap beams. Therefore, during longitudinal beam production, the longitudinal beam surface can be over-bent to overcome the springback problem. However, when the surface is over-bent, the beam's Radius (R) angle is easily deformed, resulting in product dimensions that do not meet the requirements.

[0003] In addition, the existing longitudinal beam wing surface bending device uses a metal roller for its pressure roller. When the longitudinal beam is stuck and the pressure roller continues to rotate, the pressure roller will scratch the belly surface of the longitudinal beam, thereby producing a waste beam. Summary of the Invention

[0004] In view of the defects in the prior art, the present invention provides a longitudinal beam wing surface bending device.

[0005] The present invention is achieved through the following technical solutions: A longitudinal beam wing surface bending device includes two symmetrically arranged frames, both of which are movably arranged. A metal roller is arranged between the two frames. An opening and closing mechanism is provided on the frame. The opening and closing mechanism includes a fixed shaft, an inner roller arm and an outer roller arm. One end of the inner roller arm and one end of the outer roller arm are both hinged to the fixed shaft. An inner roller is obliquely arranged on the inner roller arm, and an outer roller is provided on the outer roller arm to cooperate with the inner roller.

[0006] Preferably, a mounting frame is provided at the other end of the outer roller arm, a lead screw is provided on the mounting frame, a nut is provided on the lead screw, and both sides of the nut are hinged to the other end of the inner roller arm through a hinge shaft.

[0007] Preferably, one end of the lead screw is connected to a reducer, and the reducer is connected to a servo motor.

[0008] Preferably, a bearing seat for supporting the lead screw is provided on the mounting frame.

[0009] Preferably, a first rotating shaft is obliquely provided on the inner roller arm, and the inner roller is mounted on the first rotating shaft; a second rotating shaft perpendicular to the outer roller arm is provided on the outer roller arm, and the outer roller is mounted on the second rotating shaft.

[0010] Preferably, both the inner roller and the outer roller are truncated cone-shaped structures, the upper bottom surface of the inner roller is close to the inner roller arm, and the lower bottom surface of the outer roller is close to the outer roller arm.

[0011] Preferably, the fixed shaft is mounted on the frame via a fixing seat.

[0012] Preferably, a base is provided at the bottom of the two racks, and a forward and reverse screw is provided on the base. The forward and reverse screws are driven by a reduction motor, and a forward nut and a reverse nut are provided on the forward and reverse screws. The forward nut is connected to one rack, and the reverse nut is connected to the other rack.

[0013] Preferably, the opening and closing mechanisms on the two frames are arranged alternately.

[0014] Preferably, the surface of the metal roller is provided with a nylon layer.

[0015] The beneficial effects of the present invention are as follows: the inclined inner rollers can grip the rounded corners of the stringers, supporting them when the stringers are over-bent, thereby preventing them from deforming. The nylon layer on the metal rollers is self-lubricating and wear-resistant, preventing scratches when the stringers become stuck. This effectively reduces scrap rates, saving costs and increasing production. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0024] For ease of description, spatially relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation shown in the figures. For example, if the device in the figures is inverted, an element described as being "below" another element or feature would be positioned "above" the other element or feature. Thus, the exemplary term "below" can encompass both above and below orientations.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] The present invention is described in detail below with reference to the accompanying drawings: A longitudinal beam and wing surface bending device according to the present invention comprises two symmetrically arranged frames 1. A base 2 is disposed at the bottom of each frame 1, and a forward and reverse screw 3 is mounted on the base 2. The forward and reverse screws 3 are driven by a reduction motor. A forward nut and a reverse nut are attached to the forward and reverse screws 3. The forward nut is connected to one frame 1, and the reverse nut is connected to the other frame 1. A metal roller 4 is disposed between the two frames 1. The metal roller has a nylon layer 5 on its surface. The metal roller 4 is powered and pressed against a longitudinal beam 6. Its rotation drives the longitudinal beam 6 forward.

[0027] The frame 1 is provided with an opening and closing mechanism, and the opening and closing mechanisms on the two frames 1 are staggered. Figure 2As shown in the figure, the opening and closing mechanism includes a fixed shaft 8, an inner roller 11 arm 9, and an outer roller 12 arm 10. The fixed shaft 8 is mounted on the frame 1 via fixed seats 7 at both ends. One end of the inner roller 11 arm 9 and one end of the outer roller 12 arm 10 are both hinged to the fixed shaft 8. The inner roller 11 arm 9 is tilted with an inner roller 11, and the outer roller 12 arm 10 is equipped with an outer roller 12 that cooperates with the inner roller 11. The other end of the outer roller 12 arm 10 is provided with a mounting bracket 13, which is equipped with a lead screw 14. The mounting bracket 13 is equipped with a bearing seat 15 for supporting the lead screw 14. The lead screw 14 is equipped with a nut 16, and both sides of the nut 16 are hinged to the other end of the inner roller 11 arm 9 via hinge shafts 17. One end of the lead screw 14 is connected to a reducer 18, which is connected to a servo motor 19.

[0028] The inner roller 11 arm 9 is provided with a first rotating shaft at an angle, and the inner roller 11 is mounted on the first rotating shaft. The outer roller 12 arm 10 is provided with a second rotating shaft perpendicular to the outer roller 12 arm 10, and the outer roller 12 is mounted on the second rotating shaft. Both the inner roller 11 and the outer roller 12 are truncated cone-shaped structures, with the upper bottom surface of the inner roller 11 close to the inner roller 11 arm 9 and the lower bottom surface of the outer roller 12 close to the outer roller 12 arm 10.

[0029] During operation, the reduction motor is controlled to rotate according to the width of the longitudinal beam 6 so that the two frames 1 open and close to the appropriate position, and then the servo motor 19 is controlled to rotate to open the opening and closing mechanism, that is, the inner roller 11 and the outer roller 12 move away. When the longitudinal beam 6 enters, since the opening and closing mechanism is hinged to the frame 1 as a whole, the two wing surfaces of the longitudinal beam 6 will clamp the two inner rollers 11 into the U-shaped groove of the longitudinal beam 6. When the longitudinal beam 6 enters a certain position or the longitudinal beam 6 reaches a specified length, the servo motor 19 is controlled to rotate, thereby closing the opening and closing mechanism, so that the inner roller 11 and the outer roller 12 clamp the wing surface of the longitudinal beam 6 and over-fold the wing surface of the longitudinal beam 6. As the longitudinal beam 6 continues to feed, the over-folding of the wing surface of the longitudinal beam 6 is achieved.

[0030] like Figure 1 and Figure 4 As shown, after the two opening and closing mechanisms are tightened, since the inclination directions of the two inner rollers 11 are opposite, the highest points of the two inner rollers 11 respectively touch the two inner R corners of the longitudinal beam 6 to support the inner R corners of the longitudinal beam 6 and prevent it from deformation.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
