Description

Technical Field

[0001] The utility model relates to the technical field of welding wire processing, in particular to a welding wire straightening, feeding and winding device. Background Art

[0002] Welding wire is a metal wire welding material used as filler metal or as a conductive material. In gas welding and tungsten arc welding, welding wire is used as filler metal; in submerged arc welding, electroslag welding and other metal arc welding, welding wire is both filler metal and conductive electrode. The surface of welding wire is not coated with anti-oxidation flux.

[0003] Generally, welding wire is wound on a material tray. When in use, the material tray is directly placed on the material rack to directly produce the wire for use. The smoothness of the wire production depends on the regularity of the welding wire produced by the manufacturer when it is wound. In the final stage of traditional welding wire production, a guide wheel is set at the front end of the material tray, and the winding is completed by the reciprocating motion of the guide wheel or the reel rack. In the winding process, the welding wire does not receive enough tension, and the guiding effect cannot be well guaranteed only by the guidance of the guide wheel. This makes the winding regularity on the material tray poor, affecting the subsequent use of the product. Utility Model Content

[0027] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. The described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the related prior art, the welding wire is wound on a material tray, and when in use, the material tray is directly placed on the material rack to directly produce the wire for use, and the smoothness of the wire production depends on the regularity of the welding wire produced by the manufacturer when it is wound. In the final stage of traditional welding wire production, a guide wheel is set at the front end of the material tray, and the winding is completed by the reciprocating motion of the guide wheel or the reel rack. In the winding process, the welding wire does not receive enough tension, and the guiding effect cannot be well guaranteed only by the guidance of the guide wheel, which makes the winding regularity on the material tray poor, affecting the subsequent use of the product.

[0029] In order to solve the problems existing in the related prior art, the utility model proposes a welding wire straightening, feeding and winding device. The principle and structure of the utility model are described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] Embodiment 1

[0031] See also Figures 1 to 3 The utility model proposes a welding wire straightening and feeding winding device, which specifically includes a frame 1, a material tray 2, a reciprocating mechanism 4 and a straightening mechanism 3. The material tray 2 is fixed on the frame 1, and a motor for driving the material tray 2 to rotate is provided in the frame 1. A reciprocating mechanism 4 is provided at the front end of the frame 1. The straightening mechanism 3 is fixed on the reciprocating mechanism 4, and driven by the reciprocating mechanism 4, the straightening mechanism 3 reciprocates along the length direction of the material tray 2. The straightening mechanism 3 includes a connecting seat 3a, a mounting plate 3b, a rocker arm 3c and a guide wheel 3d. There are multiple guide wheels 3d. Guide wheels 3d are provided at the front end and the middle part of the rocker arm 3c. A tension wheel 3e is provided at the lower part of the mounting plate 3b. A plurality of guide wheels 3d arranged in a straight line are also provided on the mounting plate 3b.

[0032] Here's how it works: See Figure 2 There are 5 guide wheels and 1 tension wheel. Figure 2 The method shown passes through the two guide wheels 3d on the rocker arm 3c in sequence, then passes through the tension wheel 3e, and finally winds through the three guide wheels 3d. At the same time, the diameter of the linearly arranged guide wheels 3d gradually increases along the advancing direction of the welding wire, which can ensure the stability of rotation, because the larger the bending diameter, the smaller the internal stress of the welding wire itself. Finally, the welding wire is wound onto the material tray 2, and the material tray 2 is wound under the action of the motor. At the same time, the reciprocating mechanism 4 drives the straightening mechanism 3 to reciprocate, so that the welding wire can be tightened between the material tray and the straightening mechanism while winding, providing tension, which can ensure that the welding wire will not bend during the winding process, and the regularity of the welding wire winding can be ensured to ensure product quality.

[0033] See also Figure 2 and Figure 3 One end of the rocker arm 3c is connected to the mounting plate 3b by bolts. The mounting plate 3b is arc-shaped and has an arc-shaped groove near the end of the rocker arm 3c. An adjusting bolt 3f is provided in the middle of the rocker arm 3c. By loosening and tightening the adjusting bolt 3f, the height of the rocker arm 3c can be adjusted to adjust the welding wire from the front end entering the straightening mechanism 3 to the rear end leaving the straightening mechanism 3. In this way, the straightening effect of the straightening mechanism can be further adjusted, and the adaptability of the straightening mechanism can be further improved.

[0034] See also Figure 3One end of the rocker arm 3c is movably connected to the mounting plate 3b. The mounting plate 3b is arc-shaped and has an arc-shaped groove near the end of the rocker arm 3c. A first limit plate 3g is provided on the rocker arm 3c. A second limit plate 3h is provided on the back of the mounting plate 3b. A torsion spring 3i is provided between the first limit plate 3g and the second limit plate 3h. The torsion spring 3i can realize the effect of automatic adjustment. When the welding wire passes through with a large margin, the first limit plate 3g and the second limit plate 3h will form a larger angle, and the welding wire passes through a larger stroke of the straightening mechanism 3. When the welding wire passes through with a large margin, the first limit plate 3g and the second limit plate 3h will form a smaller angle, and the welding wire passes through a smaller stroke of the straightening mechanism 3. By adding the torsion spring 3i, the stroke of the straightening mechanism 3 can be automatically adjusted, and the purpose of tightening the welding wire can be achieved, thereby achieving the straightening effect. Please refer to Figure 1 and Figure 4 The reciprocating mechanism 4 includes a screw rod 4a and a motor for driving the screw rod to rotate. The screw rod 4a is a bidirectional screw rod. A mounting seat 4b is sleeved on the screw rod 4a. The connecting seat 3a is fixed on the mounting seat 4b. A guide rod 4c is also provided on the side of the connecting seat 3a. A guide ring 4d is provided on the guide rod 4c. The guide ring 4d is fixedly connected to the connecting seat 3a. By driving the screw rod to rotate by the motor, the straightening mechanism 3 on the mounting seat 4b can be made to reciprocate on the screw rod. The bidirectional screw rod itself has the characteristic of low vibration, which can effectively prevent the welding wire from falling off the guide wheel.

[0035] Embodiment 2

[0036] See also Figure 5 and Figure 6 The utility model also proposes another reciprocating mechanism, specifically a fixed plate and a profile 4e, a group of fixed plates are fixed at both ends of the profile 4e, and a synchronous wheel 4f is also fixed at the lower part of both ends of the profile 4e. The synchronous wheel 4f is provided with a synchronous belt 4g, and a motor for driving the synchronous wheel to rotate is provided on the side of the synchronous wheel 4f. A linear guide rail 4h is provided on the upper part of the profile 4e, and a mounting seat 4b is provided on the linear guide rail 4h. The mounting seat 4b is fixedly connected to the synchronous belt 4g, and a sensor 4i for controlling the steering of the motor is provided on the side of the profile 4e, and the sensor 4i is provided on the slide rail 4j, and can be slid on the slide rail 4j to adjust the position and then fixed.

[0037] During specific use, first set the two sensors 4i to corresponding positions, align them with the two ends of the material tray, then thread the wire, and then use the motor to drive the material tray 2 to rotate and collect the material. During the process, the motor connected to the synchronous belt 4g drives the synchronous belt 4g to rotate, and then drives the straightening mechanism on the mounting seat 4b to straighten and guide. When the mounting seat 4b moves to the position of the sensor 4i, the rotation direction of the motor connected to the synchronous wheel 4f is changed to the opposite direction, and then the synchronous belt 4g is rotated in the opposite direction, thereby realizing reciprocating motion. By setting the sensor 4i, it can adapt to material trays of different sizes, which is more convenient to use.

[0038] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
