Description

Technical Field

[0001] The utility model relates to the field of welding processing, and specifically, to a straightening device for welding processing of metal materials. Background Art

[0002] When welding and processing metal materials, welding rods are usually used. In metal welding operations, welding rods are essential materials. They consist of a metal core and an outer coating of flux. The flux is composed of a variety of minerals, ferroalloy powders, and organic substances mixed in a specific proportion and coated on the metal core to form a layer.

[0003] During the process of using a welding rod for welding, there are certain requirements for the straightness of the welding rod. This is because the bending of the welding rod during welding will affect the welding quality. If the welding rod is bent, the shape and size of the welding molten pool will be affected, resulting in uneven welding and possibly causing weld defects such as pores and cracks. In addition, the bending of the welding rod will also increase the friction during the welding process, reducing the welding speed and efficiency. Therefore, in order to ensure the welding quality, the welding rod needs to be straightened before use.

[0004] For example, Chinese Patent No. CN217990483U discloses a straightening device for the welding core of a welding rod, which includes a working box body, a winding assembly, a support column, a top pressing plate, a guide cylinder, a support frame, a support plate, a winding roller body, a bearing, a positioning rotating shaft, a limiting wheel a, and a limiting wheel b. This utility model transports the welding rod to the straightening roller for straightening and uses an adjustable winding roller body to improve the working efficiency of straightening the welding rod.

[0005] However, during the process of straightening the welding rod by this utility model, the welding rod is straightened by extrusion in the vertical direction, which can achieve certain effects for some welding rods with a small degree of bending. However, for those welding rods with a large degree of bending, it is often difficult to completely avoid new bending in the horizontal direction by using this method, which will affect the welding quality in subsequent metal welding processing. In addition, during the process of straightening the welding rod, when stretching the welding rod, it needs to be manually pulled, which will cause the stretching force applied to the welding rod to be unstable, increasing the risk of breakage of the welding rod during the straightening process, and having certain limitations in use.

[0006] In view of the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0007] In view of the problems in the related art, the utility model proposes a straightening device for welding processing of metal materials to overcome the above-mentioned technical problems existing in the existing related technologies.

[0008] For this purpose, the specific technical solution adopted by the utility model is as follows:

[0009] A straightening device for welding and processing of metal materials, comprising a bottom plate. One side of the top end of the bottom plate is provided with a support frame. The top of the outer side of the support frame is provided with a control panel. The top end of the support frame is provided with a feeding component. On one side of the feeding component, from right to left, there are arranged a guiding cylinder, a first straightening component, a second straightening component and a winding component which cooperate with the bottom plate in sequence. The structures of the first straightening component and the second straightening component are the same, and the first straightening component and the second straightening component are arranged perpendicular to each other on the top surface of the bottom plate.

[0010] Furthermore, in order to keep the force constant when stretching the welding rod, the feeding component includes a first motor arranged at the top end of the support frame. One end of the output shaft of the first motor is inserted with a rotating rod which cooperates with the support frame. The bottom end of the rotating rod is provided with a first bevel gear. On both sides of the first bevel gear, there are symmetrically arranged adjusting components which cooperate with the support frame. The bottoms of the two groups of adjusting components are inserted with a limiting rod which cooperates with the support frame. The adjusting component includes a second bevel gear meshed with one side of the first bevel gear. On the side of the second bevel gear away from the first bevel gear, there is a lead screw which cooperates with the support frame. On the circumferential outer side of the lead screw, there are symmetrically sleeved two groups of sliding blocks which cooperate with the limiting rod. Between the two groups of sliding blocks, there is a roller. The top end of the roller is provided with a second motor which cooperates with the sliding block.

[0011] Furthermore, in order to ensure the effectiveness of the straightening operation of the welding rod, the first straightening component includes a support plate arranged at the top end of the bottom plate. On both sides of the support plate, a number of limiting grooves are evenly spaced from each other. On both sides of the support plate, there are fixed strips which cooperate with the limiting grooves. Inside the limiting grooves, there are straightening parts which cooperate with the fixed strips. The straightening part includes a slider arranged inside the limiting groove. The top end of the slider is provided with a first straightening wheel. The top end of the first straightening wheel is penetrated with a first threaded rod which cooperates with the slider. The top end of the first threaded rod is provided with a second straightening wheel which is mirror-image to the first straightening wheel. The bottom end of the first threaded rod is provided with a first handle. One side of the slider is provided with a second threaded rod which cooperates with the fixed strip. One side of the second threaded rod is provided with a second handle. Both sides of the slider which cooperate with the limiting groove are of concave structures.

[0012] Furthermore, in order to carry out more convenient straightening operation on the welding rod, the winding component includes a fixed frame arranged at the top end of the bottom plate. Inside the fixed frame, there is a winding roller which cooperates with the second straightening component.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. Under the action of the feeding component, the first straightening component and the second straightening component of the present utility model, the straightening operation can be carried out on the welding rod for welding and processing of metal materials, avoiding the situation that the welding rod is bent during welding, improving the welding efficiency and ensuring the welding quality.

[0015] 2. Under the action of the first straightening component and the second straightening component of the utility model, during the straightening process of the welding rod, the welding rod can be straightened successively in the horizontal direction and the vertical direction, and through the cooperation of the first threaded rod and the second threaded rod, the welding rod of different sizes and models can be adjusted accordingly, ensuring the stability and effectiveness of the straightening operation of the welding rod.

[0016] 3.

These attached drawings are a part of the disclosure of the present utility model, mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operation principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present utility model, a straightening device for welding and processing of metal materials is provided.

[0026] Now, the present utility model will be further described in conjunction with the attached drawings and specific implementation manners. As Figures 1-4 shown, the straightening device for welding and processing of metal materials according to an embodiment of the present utility model includes a bottom plate 1. On one side of the top end of the bottom plate 1, a support frame 2 is provided. On the outer top of the support frame 2, a control panel 3 is provided. On the top end of the support frame 2, a feeding component 4 is provided. On one side of the feeding component 4, a guide cylinder 5, a first straightening component 6, a second straightening component 7 and a winding component 8 that cooperate with the bottom plate 1 are arranged in sequence from right to left; the first straightening component 6 and the second straightening component 7 have the same structure, and the first straightening component 6 and the second straightening component 7 are arranged perpendicular to each other on the top surface of the bottom plate 1 (the first straightening component 6 is horizontally placed relative to the bottom plate 1, and the second straightening component 7 is vertically placed relative to the bottom plate 1).

[0027] With the aid of the above technical solution, the present utility model can straighten the welding rods for welding and processing of metal materials under the action of the feeding component 4, the first straightening component 6 and the second straightening component 7, avoiding the bending of the welding rods during welding, improving the welding efficiency and ensuring the welding quality; under the action of the first straightening component 6 and the second straightening component 7, during the process of straightening the welding rods, the welding rods can be straightened in the horizontal direction and the vertical direction in sequence, and through the cooperation of the first threaded rod 6043 and the second threaded rod 6046, the welding rods of different sizes and models can be adjusted accordingly, ensuring the stability and effectiveness of the straightening operation of the welding rods; under the action of the feeding component 4, when straightening the welding rods, the tensile force on the welding rods can be controlled to remain unchanged, reducing the risk of breakage of the welding rods during the straightening process, and with the cooperation of the adjusting member 404, it can be applicable to welding rods of different sizes and models, improving the stability of straightening the welding rods.

[0028] In addition, it should be noted that the rewinding member 8 is a tool for welding operations, which can neatly wind the welding electrode around the winding roller 802 in the rewinding member 8. The winding roller 802 is usually made of wear-resistant, corrosion-resistant, and medium-hardness materials, such as carbon steel or stainless steel. This can ensure that the winding roller has good durability and stability during use and ensure that it will not react with the coating on the surface of the welding electrode. This is the prior art and will not be explained in detail here.

[0029] In one embodiment, for the above-mentioned feeding assembly 4, the feeding assembly 4 includes a first motor 401 arranged at the top end of the support frame 2. One end of the output shaft of the first motor 401 is inserted with a rotating rod 402 that cooperates with the support frame 2. A first bevel gear 403 is arranged at the bottom end of the rotating rod 402. Two adjusting members 404 that cooperate with the support frame 2 are symmetrically arranged on both sides of the first bevel gear 403. A limiting rod 405 that cooperates with the support frame 2 is inserted through the bottoms of the two adjusting members 404; the adjusting member 404 includes a second bevel gear 4041 meshing with one side of the first bevel gear 403. A lead screw 4042 that cooperates with the support frame 2 is arranged on the side of the second bevel gear 4041 away from the first bevel gear 403 (the thread directions of the two lead screws 4042 are the same). Two sliding blocks that cooperate with the limiting rod 405 are symmetrically sleeved on the outer circumference of the lead screw 4042. A roller 4043 is arranged between the two sliding blocks. A second motor 4044 that cooperates with the sliding block is arranged at the top end of the roller 4043; thus, the force when stretching the welding electrode can be kept constant.

[0030] The working principle of the feeding assembly 4 is as follows: When a welding electrode with a larger diameter is required, through the control panel 3, the first motor 401 is controlled and started. Under the action of the clockwise rotation of the output shaft of the first motor 401, the rotating rod 402 is driven to rotate. Under the rotation of the rotating rod 402, the first bevel gear 403 is driven to rotate. Under the rotation of the first bevel gear 403, the second bevel gears 4041 in the two adjusting members 404 are driven to rotate. Under the rotation of the second bevel gear 4041, the lead screw 4042 is driven to rotate. Under the rotation of the lead screw 4042, the two rollers 4043 are driven to move away from each other, thereby increasing the distance between the two rollers 4043;

[0031] When a welding electrode with a smaller diameter is required, through the control panel 3, the first motor 401 is controlled and started. Under the action of the counterclockwise rotation of the output shaft of the first motor 401, the rotating rod 402 is driven to rotate. Under the rotation of the rotating rod 402, the first bevel gear 403 is driven to rotate. Under the rotation of the first bevel gear 403, the second bevel gears 4041 in the two adjusting members 404 are driven to rotate. Under the rotation of the second bevel gear 4041, the lead screw 4042 is driven to rotate. Under the rotation of the lead screw 4042, the two rollers 4043 are driven to move closer to each other, thereby reducing the distance between the two rollers 4043;

[0032] After adjusting to the appropriate spacing, through the control panel 3, the second motor 4044 in the two sets of adjusting parts 404 is controlled and started. Under the reverse rotation of the output shafts of the two second motors 4044, the two sets of rollers 4043 are respectively driven to rotate. Under the rotation of the two sets of rollers 4043, feeding of the welding rod is realized with a constant tensile force.

[0033] In one embodiment, for the above-mentioned first straightening assembly 6, the first straightening assembly 6 includes a support plate 601 arranged at the top end of the bottom plate 1. A number of limiting grooves 602 are evenly spaced from each other on both sides of the support plate 601. Fixing bars 603 are arranged on both sides of the support plate 601 and are matched with the limiting grooves 602. Straightening parts 604 are arranged on the inner sides of the limiting grooves 602 and are matched with the fixing bars 603; the straightening part 604 includes a slider 6041 arranged on the inner side of the limiting groove 602. A first straightening wheel 6042 is arranged at the top end of the slider 6041. A first threaded rod 6043 (the first threaded rod 6043 is connected to the slider 6041 through a bearing) matched with the slider 6041 penetrates through the top end of the first straightening wheel 6042. A second straightening wheel 6044 opposite and mirror to the first straightening wheel 6042 is arranged at the top end of the first threaded rod 6043. A first handle 6045 is arranged at the bottom end of the first threaded rod 6043; A second threaded rod 6046 (the second threaded rod 6046 is connected to the slider 6041 through a bearing) matched with the fixing bar 603 is arranged on one side of the slider 6041. A second handle 6047 is arranged on one side of the second threaded rod 6046; Both sides of the slider 6041 matched with the limiting groove 602 are of concave structures; Thus, the effectiveness of the straightening operation on the welding rod can be ensured.

[0034] The working principle of the first straightening assembly 6 is as follows: When it is necessary to increase the spacing between the straightening parts 604 on both sides of the support plate 601, by manually rotating the second handle 6047 in the straightening part 604 clockwise, under the rotation of the second handle 6047, the slider 6041 is driven to move along the limiting groove 602, so that the straightening parts 604 on both sides of the support plate 601 move away from each other, increasing the spacing between the straightening parts 604 on both sides of the support plate 601;

[0035] When it is necessary to reduce the spacing between the straightening parts 604 on both sides of the support plate 601, by manually rotating the second handle 6047 in the straightening part 604 counterclockwise, under the rotation of the second handle 6047, the slider 6041 is driven to move along the limiting groove 602, so that the straightening parts 604 on both sides of the support plate 601 move closer to each other, reducing the spacing between the straightening parts 604 on both sides of the support plate 601;

[0036] When it is necessary to increase the distance between the first straightening wheel 6042 and the second straightening wheel 6044, by manually rotating the first handle 6045 clockwise, under the rotation of the first handle 6045, the first threaded rod 6043 is driven to rotate. Under the action of the thread, the distance between the first straightening wheel 6042 and the second straightening wheel 6044 is increased;

[0037] When it is necessary to reduce the distance between the first straightening wheel 6042 and the second straightening wheel 6044, by manually rotating the first handle 6045 counterclockwise, under the rotation of the first handle 6045, the first threaded rod 6043 is driven to rotate. Under the action of the thread, the distance between the first straightening wheel 6042 and the second straightening wheel 6044 is reduced.

[0038] In one embodiment, for the above-mentioned winding member 8, the winding member 8 includes a fixing frame 801 provided at the top end of the bottom plate 1, and a winding roller 802 that cooperates with the second straightening assembly 7 is provided inside the fixing frame 801; thus, more convenient straightening operation can be performed on the welding rod.

[0039] To facilitate the understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0040] In actual application, first, according to the size model of the welding rod, through the control panel 3, the motor 401 in the feeding assembly 4 is controlled and started. Under the rotation of the output shaft of the motor 401, the distance between the rollers 4043 in the two adjusting members 404 is adjusted. Then, by manually rotating the second handle 6047 in the straightening member 604, under the rotation of the second handle 6047, the distance between the straightening members 604 on both sides of the support plate 601 is adjusted. Then, by manually rotating the first handle 6045, under the rotation of the first handle 6045, the distance between the first straightening wheel 6042 and the second straightening wheel 6044 is adjusted;

[0041] After the adjustment is completed, the welding rod is wound and placed at the winding roller 802 in the winding member 8, and then passes through the straightening members 604 on both sides of the support plate 601 in the second straightening assembly 7 (between the first straightening wheel 6042 and the second straightening wheel 6044 on the side where the two straightening members 604 are close to each other), and then passes through the straightening members 604 on both sides of the support plate 601 in the first straightening assembly 6, and then passes through the guiding cylinder 5 to contact the adjusting member 404 in the feeding assembly 4. At this time, through the control panel 3, the motors 4044 in the two adjusting members 404 in the feeding assembly 4 are controlled and started. Under the opposite rotation of the output shafts of the two motors 4044, the rollers 4043 are driven to rotate. Under the rotation of the rollers 4043, the straightening operation of the welding rod is realized with a constant tensile force.

[0042] The working principles of the feeding component 4 and the first straightening component 6 are as described above.

[0043] In summary, by means of the above technical solutions of the present utility model, under the action of the feeding component 4, the first straightening component 6 and the second straightening component 7 of the present utility model, the electrode for metal material welding can be straightened, avoiding the bending of the electrode during welding, improving the welding efficiency and ensuring the welding quality; under the action of the first straightening component 6 and the second straightening component 7, during the straightening process of the electrode, the electrode can be straightened in the horizontal and vertical directions in sequence, and through the cooperation of the first threaded rod 6043 and the second threaded rod 6046, the electrodes of different sizes and models can be adjusted accordingly, ensuring the stability and effectiveness of the electrode straightening operation; under the action of the feeding component 4, during the straightening operation of the electrode, the tensile force applied to the electrode can be controlled to remain unchanged, reducing the risk of the electrode breaking during the straightening process, and with the cooperation of the adjusting member 404, it can be applied to electrodes of different sizes and models, improving the stability of the electrode straightening.
