Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and in particular to a welding equipment. Background Art

[0002] With the continuous development of science, the requirements for plate welding are getting higher and higher. Figure 1 and Figure 2 As shown, the high-frequency welding method using the skin effect and adjacent effect generated by high-frequency current can heat the welding edges of the first thin plate 1 and the second thin plate 2 to a welding temperature through a high-frequency heating device 3, and butt the welding edges together under the action of a force. In order to achieve continuous welding of the first thin plate 1 and the second thin plate 2, during the welding process, the first thin plate 1 and the second thin plate 2 are always located in the same horizontal plane, and a continuous intersection angle α needs to be maintained between the welding edges. The intersection angle α between the welding edges and the force F applied to the thin plate in the horizontal direction are necessary conditions for achieving high-frequency welding of thin plates.

[0003] However, for thin plate parts, due to the poor plane rigidity, it is difficult to maintain a stable convergence angle α when applying the force to the plate in the horizontal direction. Therefore, arc welding is usually used for welding thin plates instead of high-frequency welding.

[0004] Therefore, a welding device is needed to at least partially solve the problems existing in the prior art. Summary of the invention

[0005] A series of simplified concepts are introduced in the Summary of the Invention, which will be further described in detail in the Detailed Description of the Invention. The Summary of the Invention does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the scope of protection of the claimed technical solution.

[0006] In order to at least partially solve the above problem, according to a first aspect of the present invention, there is provided a welding device for welding two thin plates together, the welding device comprising:

[0008] A positioning device, the positioning device applies a force to the thin plate in the horizontal direction and the vertical direction, so that the thin plate abuts against the partition device and tilts up, and ensures that the meeting angle between the two thin plates is stable;

[0009] A high frequency heating device, the high frequency heating device is used to heat the thin plate; and

[0010] A rolling device, wherein the rolling device is arranged at a distance from the partition device,

[0011] Wherein, when the partition device and the two thin plates are in a state of relative movement, the rolling device rolls the two thin plates, and the high-frequency heating device heats the two thin plates to achieve high-frequency welding.

[0012] The welding equipment provided by the present invention overcomes the problem that two thin plates cannot be connected together by high-frequency welding. The positioning device applies force to the thin plate in the horizontal and vertical directions, so that the thin plate abuts against the partition device and tilts up, and ensures the stability of the meeting angle between the two thin plates, thereby realizing the connection of the two thin plates by high-frequency welding, and forming a continuous and good weld path between the two thin plates.

[0041] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the present invention and do not limit the present invention.

[0042] The present invention provides a welding device for high-frequency welding two thin plates, which may include a high-frequency heating device 130 , a spacer device 140 , a positioning device (not shown) and a rolling device 160 .

[0043] like Figure 3 As shown, the first thin plate 110 and the second thin plate 120 can be made of conductive materials such as metal. The first thin plate 110 and the second thin plate 120 can be placed on a support frame (not shown), so that the support frame supports the first thin plate 110 and the second thin plate 120. In an optional embodiment, the support frame can be a stand. For example, the first thin plate 110 includes a first part 111, and the second thin plate 120 includes a second part 121 opposite to the first part 111 in the horizontal direction, and the first part 111 and the second part 121 can be welded together.

[0044] The partition device 140 is used to separate two thin plates (the first thin plate 110 and the second thin plate 120). The first thin plate 110 and the second thin plate 120 can be located on both sides of the partition device 140 respectively. In order to enhance the safety of the welding equipment during use, the partition device 140 can be made of insulating materials such as ceramics, rubber or plastic.

[0045] The positioning device can apply a force to the thin plate in the horizontal direction and the vertical direction, so that the thin plate abuts against the partition device and tilts up, and ensures the stability of the meeting angle between the two thin plates. The positioning device may include a limiting device (not shown) and a squeezing device (not shown), and the limiting device can apply a force to the thin plate in the horizontal direction, so that the thin plate abuts against the partition device 140 and tilts up. The limiting device may include a first limiting member (not shown) and a second limiting member (not shown), and the first limiting member can apply a force to the first thin plate 110 in the horizontal direction, so that the first thin plate 110 abuts against the partition device 140 and tilts up, and the second limiting member can apply a force to the second thin plate 120 in the horizontal direction, so that the second thin plate 120 abuts against the partition device 140 and tilts up.

[0046] Specifically, combined with Figure 3 and Figure 4 As shown, the first thin plate 110 has a first surface 112 and a third surface 113 opposite to each other, the partition device 140 has a first surface 141 facing the first thin plate 110, the first surface 112 is close to the first surface 141, and the third surface 113 is away from the first surface 141. The first limiting member can limit the first thin plate 110 in a horizontal direction perpendicular to the first direction D1, so that the distance between the third surface 113 and the first surface 141 is smaller than the distance between the third surface 113 and the first surface 112 when the first thin plate 110 is in a free state, so that the first part 111 of the first thin plate 110 can be pressed against the partition device 140 and tilted, and the lower surface of the first part 111 in the vertical direction has a certain distance from the upper surface of the support frame.

[0047] The second thin plate 120 has a second surface 122 and a fourth surface 123 opposite to each other, the partition device 140 has a second surface 142 facing the second thin plate 120, the second surface 122 is close to the second surface 142, and the fourth surface 123 is away from the second surface 142. The second limiting member can limit the second thin plate 120 in a horizontal direction perpendicular to the first direction D1, so that the distance between the fourth surface 123 and the second surface 142 is smaller than the distance between the fourth surface 123 and the second surface 122 when the second thin plate 120 is in a free state, so that the second portion 121 of the second thin plate 120 can be pressed against the partition device 140 and tilted, and the lower surface of the second portion 121 in the vertical direction has a certain distance from the upper surface of the support frame.

[0048] Of course, the distance between the first limit member and the second limit member in the direction perpendicular to the first direction D1 can be equal to or slightly smaller than the sum of the dimensions of the first thin plate 110 and the second thin plate 120 in the direction perpendicular to the first direction D1 when they are in a free state, and a partition device is also provided between the first limit member and the second limit member, so that the first thin plate 110 and the second thin plate 120 can both abut against the partition device 140 and tilt up.

[0049] In order to ensure that the first thin plate 110 and the second thin plate 120 maintain a continuous and stable meeting angle β ( Figure 4 ), as shown in Figure 3 As shown, the extrusion device can apply a force F1 to the first thin plate 110 in the vertical direction, and the extrusion device can apply a force F2 to the second thin plate 120 in the vertical direction. That is, since the extrusion device applies a force to the first thin plate 110 and the second thin plate 120 in the vertical direction, Figure 4 In the welding process shown, the meeting angle β between the first thin plate 110 and the second thin plate 120 is a continuous and stable angle.

[0050] During the welding process, the angle of intersection β between the first thin plate 110 and the second thin plate 120 can be maintained at 1° to 10°. In this way, a good weld can be formed between the first thin plate 110 and the second thin plate 120. Preferably, during the welding process, the angle of intersection β between the first thin plate 110 and the second thin plate 120 can be 3° to 5°.

[0051] Furthermore, if Figure 4 As shown, in order to make the first thin plate 110 and the second thin plate 120 high frequency welded together, the high frequency heating device 130 is used to heat the first thin plate 110 and the second thin plate 120. In order to improve the heating efficiency, the high frequency heating device 130 can heat the first part 111 of the first thin plate 110 and the second part 121 of the second thin plate 120 respectively.

[0052] In order to smoothly weld the first thin plate 110 and the second thin plate 120 blocked by the partition device 140 together, a rolling device 160 may be provided in the second direction D2 opposite to the first direction D1. Figure 4 As shown, when the first thin plate 110 and the second thin plate 120 are both placed horizontally, the first direction D1 and the second direction D2 are opposite horizontal directions. The high-frequency heating device 130 can be arranged between the rolling device 160 and the partition device 140. In order to make the first thin plate 110 and the second thin plate 120 be pressed down evenly, the rolling device 160 can include a first rolling component 161 and a second rolling component 162. The first rolling component 161 can roll the first part 111 heated by the high-frequency heating device 130, and the second rolling component 162 can roll the second part 121 heated by the high-frequency heating device 130.

[0053] In an optional embodiment, the partition device 140 can be arranged on a support frame and can move along the first direction D1. In order to facilitate the movement of the partition device 140, the partition device 140 can be constructed as a flat plate. In this way, the partition device 140 can move relative to the first thin plate 110 and the second thin plate 120, and the surfaces of the first thin plate 110 and the second thin plate 120 relative to each other are separated from the partition device 140 respectively and abut against each other. The first rolling component 161 and the second rolling component 162 can both move along the first direction D1, the first rolling component 161 can roll the first part 111 of the first thin plate 110 heated by the high-frequency heating device 130, and the second rolling component 162 can roll the second part 121 of the second thin plate 120 heated by the high-frequency heating device 130. The first part 111 and the second part 121 abutting against each other have been heated to a certain temperature by the high-frequency heating device 130, so that high-frequency welding can be achieved.

[0054] In another optional embodiment, the partition device 140 can be configured to be fixedly arranged, and the first thin plate 110 and the second thin plate 120 can be movable relative to the partition device 140, so that the surfaces of the first thin plate 110 and the second thin plate 120 facing each other are separated from the partition device 140 and abut against each other. The first thin plate 110 and the second thin plate 120 move along the second direction D2 relative to the partition device 140, the first rolling component 161 can roll the first part 111 of the first thin plate 110 heated by the high-frequency heating device 130, and the second rolling component 162 can roll the second part 121 of the second thin plate 120 heated by the high-frequency heating device 130. The first part 111 and the second part 121 abutting against each other have been heated to a certain temperature by the high-frequency heating device 130, so that high-frequency welding can be achieved.

[0055] In another embodiment not shown, the partition device 140 can be constructed as a flat plate with a top edge extending upwardly along the first direction D1, so that the partition device 140 can move downward in the vertical direction, and the surfaces of the first thin plate 110 and the second thin plate 120 relative to each other are separated from the partition device 140 and abut against each other. The rolling device moves along the first direction D1 to roll the portions of the first thin plate 110 and the second thin plate 120 heated by the high-frequency heating device 130, and the first thin plate 110 and the second thin plate 120 abutting against each other have been heated to a certain temperature by the high-frequency heating device 130, so that high-frequency welding can be achieved.

[0056] In another embodiment not shown, the partition device 140 can be configured as a flat plate with a bottom edge extending obliquely downward along the first direction D1, and the partition device 140 can move upward along the vertical direction, and the surfaces of the first thin plate 110 and the second thin plate 120 relative to each other are separated from the partition device 140 and abut against each other. The rolling device moves along the first direction D1 to roll the portions of the first thin plate 110 and the second thin plate 120 heated by the high-frequency heating device 130, and the first thin plate 110 and the second thin plate 120 abutting against each other have been heated to a certain temperature by the high-frequency heating device 130, so that high-frequency welding can be achieved.

[0057] Since the extrusion device applies force to the first thin plate 110 and the second thin plate 120 in the vertical direction, during the process of the rolling device 160 rolling the first thin plate 110 and the second thin plate 120, the meeting angle β between the first thin plate 110 and the second thin plate 120 is a continuous and stable angle.

[0058] Furthermore, in order to enable the first thin plate 110 and the second thin plate 120 to be welded together smoothly and continuously, the welding equipment may also include a walking device (not shown) for connecting the rolling device 160 and the high-frequency heating device 130. The walking device can drive the rolling device 160 and the high-frequency heating device 130 to move along the first direction D1 at the same time, so that the rolling device 160 and the high-frequency heating device 130 can move stably, avoiding mutual interference between the rolling device 160 and the high-frequency heating device 130, so that the meeting angle β between the first thin plate 110 and the second thin plate 120 remains continuous and stable, forming a continuous and good welding path.

[0059] The walking device can also be connected to at least two of the rolling device 160, the high-frequency heating device 130 and the partition device 140, so as to improve the efficiency and stability of welding. Of course, the walking device can also be connected to the rolling device 160, the high-frequency heating device 130 and the partition device 140, so that the partition device 140, the rolling device 160 and the high-frequency heating device 130 move together.

[0060] Preferably, if Figure 3 and Figure 4As shown, the first surface 112 of the first thin plate 110 can be pressed against the first surface 141 of the partition device 140, and the second surface 122 can be pressed against the second surface 142 of the partition device 140. The extrusion device applies a force to the first thin plate 110 and the second thin plate 120 in the vertical direction, and a continuous and stable angle of intersection β is maintained between the first thin plate 110 and the second thin plate 120. The partition device 140 moves along the first direction D1, and the first surface 112 and the second surface 122 are separated from the partition device 140 respectively and pressed against each other. The rolling device 160 rolls the first part 111 and the second part 121 pressed against each other by the high-frequency heating device 130, thereby realizing high-frequency welding of the first surface 112 and the second surface 122, and forming a continuous and good welding path between the first thin plate 110 and the second thin plate 120.

[0061] Of course, the spacer device 140 can be configured to be fixedly arranged, the first thin plate 110 and the second thin plate 120 can move relative to the spacer device 140 along the second direction D2, and the first surface 112 and the second surface 122 can also be separated from the spacer device 140 and abut against each other. The rolling device 160 rolls the first part 111 and the second part 121 abutting against each other heated by the high-frequency heating device 130, thereby achieving high-frequency welding of the first surface 112 and the second surface 122.

[0062] Compared with arc welding, the high-frequency welding of the welding equipment provided by the present invention has the advantages of no consumption of welding materials, low cost and high welding speed, and can greatly reduce its production cost. According to the welding equipment provided by the present invention, the problem that two thin plates cannot be connected together by high-frequency welding is overcome. The positioning device applies force to the thin plate in the horizontal direction and the vertical direction, so that the thin plate abuts against the partition device and tilts up, and ensures the stability of the meeting angle between the two thin plates, so that the two thin plates are connected together by high-frequency welding, and a continuous and good welding path is formed between the two thin plates.
