Description

Technical Field

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

[0002] The welding rod is composed of a welding core and a coating. The metal core covered by the coating in the welding rod is called the welding core. The welding core is generally a steel wire with a certain length and diameter. When welding, the welding core has two functions: one is to conduct welding current, generate an arc to convert electrical energy into heat energy, and the other is to melt the welding core itself as filler metal to fuse with the liquid parent metal to form a weld. When welding with welding rods, the welding core metal accounts for a part of the entire weld metal.

[0003] Generally, in the production of welding rods, the raw materials are first drawn to reduce their diameter to a certain value, and then they are cut into a certain length. After that, they are coated with a thick coating and sent to a furnace for drying. The produced welding rods must not bend. Therefore, in the production process of the welding core, it is required to straighten the welding core as necessary. The traditional straightening device only uses two sets of positioning wheels for straightening and fixing, and its flexibility is poor. When the size of the welding core is adjusted, the straightening effect becomes relatively poor. Utility Model Content

[0031] In the related prior art, the production of welding rods first involves drawing the raw materials to reduce their diameter to a certain value, then cutting them into a certain length, and then wrapping them with a thick coating before sending them into a furnace for drying. The produced welding rods are required not to bend, so the welding core is required to be straightened during its production process. The traditional straightening device only uses two sets of positioning wheels for straightening and fixing, and its flexibility is poor. When the size of the welding core is adjusted, the straightening effect becomes relatively poor.

[0032] In order to solve the problems existing in the related prior art, the utility model proposes a welding rod welding core straightening and punching device. The principle and structure of the utility model are described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] Embodiment 1

[0034] See also Figures 1 to 5 The utility model provides a welding rod welding core straightening and punching device, comprising a wire feeding device 1, a straightening device 2 and a cutting device 3, wherein the wire feeding device 1, the straightening device 2 and the cutting device 3 are arranged linearly;

[0035] Please refer to Figure 1 and Figure 2 The wire feeding device 1 includes a wire feeding wheel 101 and an auxiliary wheel 102, the wire feeding wheel 101 and the auxiliary wheel 102 are located in the same vertical plane, the wire feeding wheel 101 is driven by a first motor 103, and the welding core passes between the wire feeding wheel 101 and the auxiliary wheel 102. At the same time, as a preference, there are two wire feeding wheels 101 and two auxiliary wheels 102 and they are located in the same vertical plane, and the two wire feeding wheels 101 are connected by a synchronous belt, or a first motor 103 is correspondingly provided for the two wire feeding wheels 101, which can provide greater traction.

[0036] See also Figure 2 and Figure 3 , there are two straightening devices 2, and they are respectively set horizontally and vertically. Taking the vertically set straightening device as an example, the vertical direction is defined as the up and down direction, the front side close to the fixed wheel, and the forward movement direction of the welding core is the left and right direction. The straightening device 2 includes a fixed wheel 201, an adjusting wheel 202 and a mounting plate 203, and the fixed wheel 201 is located below the adjusting wheel 202 and is staggered. The fixed wheel 201 and the adjusting wheel 202 are multiple and fixed on the mounting plate 203. The multiple fixed wheels 201 are arranged linearly, and the adjusting wheel 202 is connected to the movable block 204. The movable block 204 can slide relatively under the drive of the first screw 205, that is, by rotating the first screw 205, the movable block 204 and the adjusting wheel 202 can be driven to adjust up and down, and then the distance between the fixed wheel 201 and the adjusting wheel 202 can be adjusted. In this way, different distances are selected for welding cores of different sizes to achieve a stable straightening effect;

[0037] See also Figure 1 and Figure 2 The cutting device 3 includes a second motor 301, a flywheel 302, a first linear guide 303, a second linear guide 304, a cutter 305 and a wire guide block 306. The second motor 301 and the flywheel 302 are belt-driven. The first linear guide 303 and the second linear guide 304 both include guide rails and sliders. The slider of the first linear guide 303 is movably connected to the flywheel 302. One side of the wire guide block 306 is fixed on the guide rail of the first linear guide 303, and the other side is fixed on the slider of the second linear guide 304. The second linear guide 304 is horizontally arranged. The cutter 305 is fixed on the slider of the first linear guide 303. The position of the cutter 305 corresponds to the position of the wire guide block 306. A cover plate 307 is provided on one side of the flywheel 302. The material used for the cover plate 307 is a transparent acrylic plate.

[0038] The welding core passes through the inside of the wire guide block 306, and the flywheel 302 is driven to rotate by the second motor 301, and then the first linear guide is driven to make left and right reciprocating motion in the horizontal direction, and at the same time, the slider of the second linear guide is also driven to make left and right reciprocating motion, and the slider of the first linear guide is driven to make up and down reciprocating motion, thereby driving the cutter 305 and the wire guide block 306 to make up and down reciprocating motion relative to each other. When the slider of the first linear guide 303 moves to the lowest point of the horizontal height, the welding core is punched and cut.

[0039] The specific working principle is as follows:

[0040] The welding core first passes between the wire feeding wheel 101 and the auxiliary wheel 102, which provide power for the movement of the welding core. Then the welding core passes through the middle of the fixed wheel 201 and the adjusting wheel 202 of the two straightening devices 2 in turn, and the distance between the fixed wheel 201 and the adjusting wheel 202 is adjusted by the first screw 205, so that the welding core can be effectively straightened after passing through. The straightened welding core is then inserted into the hole of the wire guide block 306, the diameter of the hole is the same as the diameter of the welding core, and with the action of the second motor 301, the welding core is cut off during the movement of the welding core.

[0041] Embodiment 2

[0042] The traditional straightening mechanism can only provide a set of relative external forces to achieve the straightening effect. For example, if the straightening mechanism is placed horizontally, it provides a set of external forces in the horizontal direction. If the straightening mechanism is placed vertically, it provides external forces in the up and down directions. However, it cannot provide external forces at other angles to improve the straightening effect. Therefore, in another embodiment, the adjusting wheel can be adjusted forward and backward and rotated along the forward direction of the welding core. This can provide external forces at more angles to achieve better straightening effects. For details, please refer to Figures 3 to 5A second screw rod 206 is also provided on one side of the movable block 204. Driven by the second screw rod 206, the movable block 204 slides along the length direction of the second screw rod 206. The adjusting wheel 202 realizes offset adjustment as the movable block 204 slides. Through the rotation of the second screw rod 206, the entire movable block 204 is driven to move in the front-rear direction.

[0043] In addition, a bolt slider 207 is sleeved on the first screw rod 205, and a corresponding slide rail is provided on the mounting plate 203. The bolt slider 207 slides in the corresponding slide rail and the sliding direction is the same as the adjustment direction of the second screw rod 206. In this way, it can be ensured that the first screw rod 205 can rotate normally to drive the movable block 204 to move in the up and down directions. Similarly, the second screw rod 206 also has the same structure, that is, the second screw rod 206 is also provided with a bolt slider 207 and a corresponding slide rail that can slide up and down. That is, when the first screw rod 205 rotates, the second screw rod 206 and the bolt slider 207 sleeved on the second screw rod 206 move up and down with the movable block 204. When the second screw rod 206 rotates, the first screw rod 205 and the bolt slider 207 sleeved on the first screw rod 205 move forward and backward with the movable block 204. The position of the adjusting wheel 202 in the up and down, front and back directions is adjusted by the first screw rod 205 and the second screw rod 206. Please refer to Figure 5 A cavity is provided inside the movable block 204, and an adjusting block 208 is provided in the cavity. Both sides of the adjusting block 208 are connected to the inner wall of the movable block 204 and can rotate around the axis. An adjusting wheel 202 is provided at one end of the adjusting block 208, and a fan-shaped turbine 209 is provided at the other end. A worm 210 matched with the turbine 209 is also provided in the movable block 204, and the worm 210 extends to the outside of the movable block 204. Through the turbine and worm structure, the angular rotation of the adjusting wheel 202 connected to the adjusting block 208 is realized.

[0044] Through the above structure, the adjusting wheel 202 can be adjusted in the up-down and front-back directions, and the angle can be adjusted accordingly, so that external forces can be applied to the welding core at multiple angles. Compared with the traditional external forces in two opposite directions, the straightening effect can be effectively improved.

[0045] 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.
