Description

Technical Field

[0002] Roll forming is a processing method that bends and shapes sheet metal by passing it through rotating rollers. The sheet metal is gradually bent by a series of rollers to eventually form the desired structure. After roll forming, the sheet metal will have a gap at one end that needs to be welded, so subsequent processing such as cutting and welding is required to meet the final requirements of the product.

[0003] In the relevant technical solutions, when the sheet metal is formed by roll bending, the extrusion rollers are usually used to squeeze and limit the two sides of the sheet metal during welding, and then the welding device is used to weld and fix the position to be welded on the formed sheet metal.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0046] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0047] As described in the background section, when welding roll-formed sheets in related technologies, the sheets may spring back; this is especially true for thinner sheets (thickness less than 0.15mm), where the probability of springback is higher. After springback, the sheets at the welding position cannot be aligned because they are not on the same plane, affecting welding quality. Research has found that the cause of this problem is that the extrusion rollers in related technologies can only limit the sides of the roll-formed sheet, but cannot limit the top and bottom ends. To facilitate subsequent welding, the welding position is generally set at the top. Therefore, when the sheet springs back, a height difference occurs at the welding position, thus affecting welding quality.

[0048] In view of this, the embodiments of this application aim to provide a welding auxiliary device and welding system. By setting up opposing first and second limiting mechanisms, the first limiting mechanism's first limiting groove limits the welding position of the roll-formed sheet metal, and the second limiting mechanism's second limiting groove limits the bottom surface of the roll-formed sheet metal. A welding device is then used to weld the sheet metal through the welding groove on the first limiting mechanism. Due to the function of the first and second limiting grooves, the probability of springback in the roll-formed sheet metal is reduced, keeping the misalignment of the sheet metal at the welding position within a reasonable range, thereby helping to ensure welding quality.

[0049] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the content of this application. It should be noted that, in this embodiment, the first direction X, the second direction Y, and the third direction Z are three different directions in three-dimensional space. For example, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other, and the third direction Z can be, for example, the forward direction of the sheet 1 after roll forming.

[0050] Please refer to Figures 1-6This embodiment provides a welding auxiliary device 10, including a first limiting mechanism 100 and a second limiting mechanism 200 arranged opposite each other along a first direction X. The first limiting mechanism 100 has a first limiting groove 101 on the side facing the second limiting mechanism 200, which limits the welding position of the roll-formed sheet 1. It is understood that the shape of the first limiting groove 101 is adapted to the shape of the welding position of the roll-formed sheet 1, and the projection of the first limiting groove 101 in a plane perpendicular to the third direction Z can be, for example, square or arc-shaped. In this embodiment, the first limiting mechanism 100 can limit and adjust the welding position of the roll-formed sheet 1 and the two sides near the welding position. The second limiting mechanism 200 has a second limiting groove 201 on the side facing the first limiting mechanism 100, which limits the bottom surface of the roll-formed sheet 1. It is understandable that the shape of the second limiting groove 201 is adapted to the shape of the bottom surface of the roll-formed sheet 1. In the plane perpendicular to the third direction Z, the projection of the second limiting groove 201 can also be square or arc-shaped, for example. In this embodiment, the second limiting mechanism 200 can limit and adjust the bottom surface of the roll-formed sheet 1 and the two sides near the bottom surface, mainly playing an auxiliary adjustment role.

[0051] As described above, this embodiment uses the first limiting groove 101 to limit the welding position of the roll-bent plate 1, and the second limiting groove 201 to limit the bottom surface of the roll-bent plate 1. Due to the function of the first limiting groove 101 and the second limiting groove 201, the probability of springback of the roll-bent plate 1 is reduced, and the misalignment of the plate at the welding position is kept within a reasonable range, which helps to ensure the welding quality.

[0052] In this embodiment, the first limiting mechanism 100 and the second limiting mechanism 200 can be installed on the same part, or the first limiting mechanism 100 and the second limiting mechanism 200 can be installed on different parts, which can be set according to the needs.

[0053] For example, the welding auxiliary device 10 of this embodiment further includes a mounting bracket, which includes a first mounting plate 310 and a second mounting plate 320. The first mounting plate 310 is used to connect to the ground, for example, by fixing the first mounting plate 310 to the ground with bolts. The second mounting plate 320 is vertically arranged on the first mounting plate 310, and the second mounting plate 320 and the first mounting plate 310 can also be connected by bolts, for example. The first limiting mechanism 100 and the second limiting mechanism 200 can both be fixed on the second mounting plate 320.

[0054] Please continue to refer to Figures 2-4In this embodiment, the first limiting mechanism 100 includes a first limiting block 110. A first adjusting block 120 and a second adjusting block 130 are provided on the side of the first limiting block 110 facing the second limiting mechanism 200. The first adjusting block 120 and the second adjusting block 130 are spaced apart along the second direction Y, and together they form a first limiting groove 101. As can be understood from the accompanying drawings, the first limiting groove 101 forms openings on both sides in the third direction Z to allow the rolled sheet 1 to pass through. The first limiting block 110 forms the bottom wall of the first limiting groove 101, and the first adjusting block 120 and the second adjusting block 130 respectively form the two side walls of the first limiting groove 101. In this embodiment, the first adjusting block 120 and the second adjusting block 130 are slidably disposed on the first limiting block 110 along the second direction Y, thereby facilitating the adjustment of the positions of the first adjusting block 120 and the second adjusting block 130 in the second direction Y according to the size of the rolled sheet 1.

[0055] For example, in this embodiment, the first limiting block 110 is provided with a first adjusting mechanism and a second adjusting mechanism on both sides along the second direction Y. The first adjusting mechanism is connected to the first adjusting block 120 and can drive the first adjusting block 120 to slide on the first limiting block 110, so as to adjust the position of the first adjusting block 120 in the second direction Y. The second adjusting mechanism is connected to the second adjusting block 130 and can drive the second adjusting block 130 to slide on the first limiting block 110, so as to adjust the position of the second adjusting block 130 in the second direction Y.

[0056] Specifically, the first adjustment mechanism in this embodiment includes a first fixed base 121 and a first adjusting rod 122. The first fixed base 121 is fixed to one side of the first limiting block 110 along the second direction Y. The first fixed base 121 and the first limiting block 110 can be fixed by means of welding, screwing, etc. The first adjusting rod 122 is rotatably disposed in the first fixed base 121. For example, the first fixed base 121 can be provided with a corresponding mounting groove, and the first adjusting rod 122 is provided with two flanges. The two flanges are respectively engaged with the two sides of the mounting groove, thereby ensuring that the first adjusting rod 122 and the first fixed base 121 can rotate relative to each other. The first adjusting block 120 is provided with a first adjusting hole, which can be a threaded hole. The first adjusting rod 122 is threadedly connected to the first adjusting hole. By rotating the first adjusting rod 122, the first adjusting block 120 can slide along the second direction Y (for example, rotating the first adjusting rod 122 clockwise can make the first adjusting block 120 slide towards the second direction Y). Figure 4 As shown, sliding to the left and rotating the first adjusting rod 122 counterclockwise can cause the first adjusting block 120 to move in the second direction Y towards... Figure 4 (As shown, slide on the right), thereby changing the position of the first adjusting block 120 to clamp the rolled sheet 1 and prevent it from springing back and deforming.

[0057] Similarly, the second adjustment mechanism includes a second fixed seat 131 and a second adjusting rod 132. The second fixed seat 131 is fixed along the second direction Y to the other side of the first limiting block 110. The second fixed seat 131 and the first limiting block 110 can be fixed by means of welding, screwing, etc. The second adjusting rod 132 is rotatably disposed in the second fixed seat 131. For example, the second fixed seat 131 can be provided with a corresponding mounting groove, and the second adjusting rod 132 is provided with two flanges. The two flanges are respectively engaged with the two sides of the mounting groove, thereby ensuring that the second adjusting rod 132 and the second fixed seat 131 can rotate relative to each other. The second adjusting block 130 is provided with a second adjusting hole, which can be a threaded hole. The second adjusting rod 132 is threadedly connected to the second adjusting hole. By rotating the second adjusting rod 132, the second adjusting block 130 can slide along the second direction Y (for example, rotating the second adjusting rod 132 clockwise can make the second adjusting block 130 slide along the second direction Y towards the second direction). Figure 4 As shown, sliding to the right and rotating the second adjusting rod 132 counterclockwise can cause the second adjusting block 130 to move in the second direction Y. Figure 4 (As shown, slide to the left), thereby changing the position of the second adjusting block 130 to clamp the rolled sheet 1 and prevent it from springing back and deforming.

[0058] Furthermore, to ensure that the first adjusting block 120 and the second adjusting block 130 do not deviate during movement, the first limiting block 110 in this embodiment is provided with a first guide plate 141 and a second guide plate 142 on both sides along the third direction Z. The first guide plate 141 includes a first connecting section 1411 and a first guide section 1412, with the first guide section 1412 perpendicular to the first connecting section 1411. The first connecting section 1411 and the first guide section 1412 are generally L-shaped. The second guide plate 142 includes a second connecting section 1421 and a second guide section 1422, with the second guide section 1422 perpendicular to the second connecting section 1421. The second connecting section 1421 and the second guide section 1422 are generally L-shaped. The first connecting section 1411 and the second connecting section 1421 are fixedly connected to both sides of the first limiting block 110 along the third direction Z, for example, by welding or bolting. The first guide segment 1412 and the second guide segment 1422 are located on the side of the first limiting block 110 facing the second limiting mechanism 200, and a gap is formed between the first guide segment 1412 and the second guide segment 1422 and the first limiting block 110. The first adjusting block 120 and the second adjusting block 130 are both located between the first guide segment 1412 and the second guide segment 1422 and the first limiting block 110, so that they can move along the second direction Y under the guidance of the first limiting block 110, the first guide plate 141 and the second guide plate 142. In this embodiment, the first guide plate 141 includes two first guide segments 1412, which are spaced apart along the second direction Y, and the second guide plate 142 includes two second guide segments 1422, which are spaced apart along the second direction Y, thereby avoiding obstruction of the opening of the first limiting groove 101 in the third direction Z.

[0059] In this embodiment, the first limiting mechanism 100 is further provided with a welding groove 102, which connects to the first limiting groove 101. In use, an external welding device can weld the desired position of the roll-formed sheet 1 through the welding groove 102 to obtain the desired product. For example, the welding groove 102 can be provided on the first limiting block 110, penetrating the first limiting block 110 along the first direction X, thereby facilitating the insertion of the welding device into the first limiting groove 101.

[0060] Please continue to refer to Figure 2 , Figure 3 and Figure 5In one possible implementation, the first limiting block 110 of this embodiment is further provided with a plurality of negative pressure holes 103. The plurality of negative pressure holes 103 are connected to the first limiting groove 101, and the plurality of negative pressure holes 103 are used to connect to an external negative pressure source. It can be understood that the plurality of negative pressure holes 103 can be connected to the bottom wall of the first limiting groove 101. By using an external negative pressure source to make the plurality of negative pressure holes 103 form negative pressure, the welding position of the roll-formed plate 1 can be adsorbed onto the bottom wall of the first limiting groove 101 by the action of negative pressure, ensuring that the plate at the welding position is always in contact with the bottom wall of the first limiting groove 101, avoiding misalignment of the plate at the welding position, thereby improving the welding quality.

[0061] In one possible implementation, the first limiting block 110 of this embodiment can be a metal block, such as a copper block, to ensure good heat conduction at the welding position. A ceramic plate 150 is also provided on the side of the first limiting block 110 facing the second limiting mechanism 200, and the ceramic plate 150 is located within the first limiting groove 101. That is, the ceramic plate 150 is in direct contact with the roll-formed sheet 1. The ceramic plate 150 improves wear resistance, thereby extending service life. The aforementioned plurality of negative pressure holes 103 can be formed on the ceramic plate 150.

[0062] Furthermore, in order to reduce heat accumulation within the first limiting block 110 and improve its heat dissipation efficiency, this embodiment also provides a coolant pipeline within the first limiting block 110. The surface of the first limiting block 110 is provided with a coolant inlet 111 and a coolant outlet 112. The coolant pipeline is connected to the coolant inlet 111 and the coolant outlet 112, and the coolant inlet 111 and the coolant outlet 112 can be connected to external cooling equipment.

[0063] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the first limiting mechanism 100 is slidably disposed on the second mounting plate 320, thereby facilitating the adjustment of the position of the first limiting mechanism 100 in the first direction X. For example, along the first direction X, a mounting groove 321 is formed at the end of the second mounting plate 320 away from the first mounting plate 310. The first limiting mechanism 100 also includes a mounting base 160 and a limiting base 170. The two ends of the mounting base 160 along the second direction Y are respectively connected to the first limiting block 110 and the limiting base 170, and the mounting base 160 is slidably disposed within the mounting groove 321.

[0064] In one possible implementation, the second mounting plate 320 of this embodiment is further connected to a fixing plate 330 and a third adjusting rod 340 at the end opposite to the first mounting plate 310. The fixing plate 330 is provided with a third adjusting hole, which can be a threaded hole. The third adjusting rod 340 passes through the third adjusting hole and is threadedly connected to it. The mounting base 160 is also provided with a connecting groove 1601, and the third adjusting rod 340 is fixedly connected to the connecting groove 1601. With the above structure, the third adjusting rod 340 can be rotated to drive the first limiting mechanism 100 to move along the first direction X.

[0065] Furthermore, the mounting base 160 in this embodiment includes a body 161 and a guide portion 162. The guide portion 162 is disposed on both sides of the body 161 along a third direction Z, and the guide portion 162 is perpendicular to the body 161. The body 161, the guide portion 162, and the limiting seat 170 together form a guide groove, and the end of the second mounting plate 320 facing away from the first mounting plate 310 passes through the guide groove. With the above structure, the guide groove and the cooperation of the second mounting plate 320 can be used to guide the first limiting mechanism 100 when it moves along the first direction X.

[0066] In this embodiment, the limiting seat 170 is further provided with a limiting groove on the side facing the second mounting plate 320, and a clamping block 171 is provided in the limiting groove. The limiting seat 170 is also provided with an abutment member, which passes through the limiting seat 170 and connects with the clamping block 171. The abutment member is used to push the limiting block to abut against the second mounting plate 320, thereby ensuring that the first limiting mechanism 100 can clamp the second mounting plate 320.

[0067] Please continue to refer to Figure 2 In this embodiment, a first adapter plate 180 is also provided between the mounting base 160 and the first limiting block 110. The first adapter plate 180 can be fixedly connected to the mounting base 160, for example, by bolts or other parts. The first adapter plate 180 and the first limiting block 110 are connected by multiple reinforcing ribs 190. The reinforcing ribs 190 are generally L-shaped, with one side of the reinforcing rib 190 fixedly connected to the first adapter plate 180 and the other side fixedly connected to the first limiting block 110. The reinforcing ribs 190 can be connected and fixed to the first adapter plate 180 and the first limiting block 110, for example, by welding, bolting, or other methods.

[0068] Please continue to refer to Figure 1 and 6 The second limiting mechanism 200 in this embodiment includes a second limiting block 210, and the second limiting block 210 is provided with a second limiting groove 201 on the side facing the first limiting mechanism 100.

[0069] For example, the second limiting mechanism 200 also includes a fixed base 220, which is connected to the second mounting plate 320. The second limiting block 210 is slidably disposed on the fixed base 220 along the second direction Y, so as to facilitate the adjustment of the position of the second limiting block 210 along the second direction Y as needed.
