Description

Technical Field

[0001] The invention belongs to the technical field of sheet metal processing, and in particular relates to welding equipment for sheet metal processing. Background Art

[0002] Sheet metal parts are products processed by sheet metal technology. We cannot live without sheet metal parts in our daily life. Sheet metal parts are made by filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal sheet bending, die forging, water jet cutting. The main processes of sheet metal processing include shearing, bending and buckling, bending, welding and riveting.

[0003] At present, laser welding machines are mostly used for welding processes. Due to the needs of actual production, in the process of welding sheet metal parts, it is often necessary to weld between two sheet metal parts. Sheet metal parts can usually only be welded on one side at a time, and the welding results of the other side cannot be guaranteed after welding on one side is completed. It is necessary to change the side for observation to determine the weld effect or perform a second welding. Manually changing the side will have a greater labor intensity, and it will be more difficult for slightly larger sheet metal parts to change the side. Therefore, a welding device for sheet metal processing is proposed. Summary of the invention

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Reference Figure 1-17 The embodiment of the present invention provides a welding device for sheet metal processing, comprising an outer shell 1, a shell door 2 is pinned to the front of the outer shell 1, a glass window 3 is arranged in the middle of the shell door 2, and a handle 4 is arranged in the front of the outer shell 1; two assembly rods 01 are arranged in the outer shell 1, and a plurality of transport cylinders 12 are screwed and arranged in the middle of the assembly rod 01 in equal proportion, and the transport cylinders 12 are used to transport sheet metal; a motor 6 is arranged on the upper wall of the assembly rod 01, and a power shaft of the motor 6 is fixedly connected to a threaded rod 7, and an end of the threaded rod 7 away from the motor 6 is screwed to an assembly seat 8 fixedly connected to the assembly rod 01, and a U-shaped frame 5 is screwed to the threaded rod 7, and a motor 2 9 is arranged on one side of the U-shaped frame 5, and a power shaft of the motor 2 9 is connected to a threaded rod 4 10, and the threaded rod 4 10 is screwed to a variable platform 11, and a cylinder 111 is connected to the bottom of the variable platform 11, and the movable part of the cylinder 111 The end is connected to the laser welding head 112, and the inner wall of the two assembly rods 01 is fixedly connected to the cylinder 2 113 on the opposite side. The movable end of the cylinder 2 113 is fixedly connected to the limiting plate 114. The two sheet metals to be welded are placed on the transport cylinder 12 by opening the shell door 2, which can facilitate the transportation of the sheet metal. When the sheet metal is transported to the appropriate position, the cylinder 2 113 is started to allow the cylinder 2 113 to pull the limiting plate 114 to lock the sheet metal to ensure the stability of the sheet metal during welding. Then, the motor 2 9 is started, and the power shaft of the motor 2 9 pulls the threaded rod 4 10 to rotate so that the cylinder 1 111 and the laser welding head 112 are moved to the weld to be welded. Then, the cylinder 111 is operated to pull the laser welding head 112 to the appropriate position, and then the motor 1 6 can be started, and the power shaft of the motor 1 6 pulls the threaded rod 1 7 to rotate to move the U-shaped frame 5, so that displacement welding can be achieved;

[0045] It also includes: a supporting unit 13, a lifting and slow-falling unit;

[0046] The supporting unit 13 is installed in the gap between the transport cylinders 12, and includes a displacement unit 1320, a rotating unit 132 installed in the displacement part of the displacement unit 1320, and a right-angle piece 131 installed in the rotating head of the rotating unit 132. During the initial stage, the transverse surface of the right-angle piece 131 is in a transverse state, and the transverse surface and the upper wall surface of the transport cylinder 12 are in the same plane, or there is a slight gap without exceeding the upper wall surface of the transport cylinder 12, and the vertical surface faces the central area of ​​the transport cylinder 12, and the right-angle piece 131 and the rotating unit 132 are on one side of the transport cylinder 12.

[0047] The lifting and slow-falling unit comprises a traction unit 16 , a lifting unit 14 and a slow-falling unit 15 connected to the traction unit 16 . The lifting unit 14 is used to lift the other side of the sheet metal upward under the influence of the traction unit 16 while the right-angle piece 131 restricts the sheet metal from one side of the sheet metal; the displacement unit 1320 is used to drive the rotating unit 132 to displace toward the other side of the sheet metal while the other side of the sheet metal is lifted, and the rotating unit 132 is used to drive the right-angle piece 131 to rotate while being displaced by the displacement unit 1320, so that the lateral surface of the right-angle piece 131 is tilted upward; the slow-down unit 15 is used to rotate from one side of the sheet metal upward under the operation of the traction unit 16 while the lifting unit 14 lifts the other side of the sheet metal upward, and while the sheet metal is lifted up to a specific angle tilted toward the slow-down unit 15 under the influence of the lifting unit 14 and the right-angle piece 131, the slow-down unit 15 rotates upward until it fits with the sheet metal, and after fitting, the slow-down unit 15 is used to rotate downward due to the influence of the traction unit 16.

[0048] When the slow-descent unit 15 rotates upward to fit the sheet metal, the transverse and vertical surfaces of the right-angle piece 131 each have an angle with the upper wall of the motor three 137, that is, the right-angle piece 131 rotates to the center area at this time, and the transverse surface, the vertical surface and the sheet metal have angles.

[0049] Moreover, the distance between the bonding area between the slow lowering unit 15 and the sheet metal and the bonding area between the right-angle piece 131 and the sheet metal exceeds 1 / 2 of the short side of the sheet metal, which is beneficial to the support of the bonding area between the slow lowering unit 15 and the sheet metal, and the supporting points of the bonding area between the right-angle piece 131 and the sheet metal, and can maintain the stability of the sheet metal.

[0050] When the right-angle piece 131 rotates to the horizontal surface of the right-angle piece 131 in the horizontal state, the horizontal surface and the upper wall of the transport cylinder 12 are in the same plane; when the right-angle piece 131 rotates to the vertical surface of the right-angle piece 131 in the horizontal state, the vertical surface and the upper wall of the transport cylinder 12 are in the same plane. This arrangement is beneficial for applying restrictions to the sheet metal at the beginning, and is also beneficial for placing the sheet metal on the transport cylinder 12 after the surface change is completed.

[0051] The transverse and vertical surfaces of the right-angle piece 131 are both provided with undulating silicone pads 1312, which are beneficial for providing good support for the sheet metal as the lower supporting point and ensuring the stability of this supporting point.

[0052] The above process is used to change the surface of sheet metal:

[0053] In the initial stage, after the sheet metal is welded, the sheet metal is in the face-changing area of ​​the transport cylinder 12, and the limiting plate 114 is kept away from the welded sheet metal.

[0054] In order to achieve the purpose of changing the surface, one or more supporting units 13 are installed to serve as supporting points on one side of the sheet metal and as support for changing the surface. One or more lifting and slow-down units are installed to lift the sheet metal from the other side, and after it is opened, it can slowly drop from one side. Moreover, in order to make the surface changing more stable and efficient, when there is only one supporting unit 13, several lifting and slow-falling units can be installed, for example, two. The lifting and slow-falling unit and the supporting unit 13 are respectively installed in different gaps, and each lifting and slow-falling unit is also respectively installed in different gaps, and the supporting unit 13 is located between the two lifting and slow-falling units, that is, the lifting and slow-falling unit can be installed on both sides of the supporting unit 13 in a mirror-image manner; and, when there is only one lifting and slow-falling unit, several supporting units 13 can be installed, for example, two. At this time, the lifting and slow-falling unit and the supporting unit 13 can be respectively installed in different gaps, and each supporting unit 13 is also respectively installed in different gaps, and the lifting and slow-falling unit is located between the two supporting units 13, that is, the supporting units 13 are installed on both sides of the lifting and slow-falling unit in a mirror-image manner.

[0055] The lifting and slow-falling unit and the supporting unit 13 are respectively arranged in different gaps in order to prevent the operations of the two from being affected by each other during the same gap.

[0056] In this solution, two supporting units 13 and two lifting and slow-falling units are used, and the two supporting units 13 are located between the two lifting and slow-falling units, and each unit is located in a gap. Moreover, the two lifting and slow-falling units are located between the two supporting units 13. Such an arrangement can ensure the stability of the surface change and the position after the surface change.

[0057] Next, the right-angle piece 131 is rotated by the rotating unit 132 until the lateral surface of the right-angle piece 131 is in a lateral state, and the rotating unit 132 and the right-angle piece 131 are pulled by the displacement unit 1320, so that the right-angle piece 131 restricts the sheet metal from one side of the sheet metal; during the restriction, the lateral surface of the right-angle piece 131 is in contact with the lower wall surface of the sheet metal, and one side of the sheet metal is in contact with the lower side of the vertical surface of the right-angle piece 131.

[0058] Then, the rotating unit 132 and the right-angle piece 131 are pulled. At this time, the rotating unit 132 rotates the right-angle piece 131 together to tilt the lateral surface upward. At this time, the pulling unit 16 drives the lifting unit 14 to rotate upward to lift the other side of the sheet metal upward. The pulling unit 16 drives the slow-down unit 15 to rotate upward from one side of the sheet metal.

[0059] Subsequently, the sheet metal is lifted to a vertical position due to the lifting unit 14 and the right-angle piece 131, and then tilted to a set angle toward the slow-descent unit 15, and the slow-descent unit 15 rotates to fit the sheet metal; after fitting, the traction unit 16 drives the lifting unit 14 and the slow-descent unit 15 to rotate downwards respectively in a counterclockwise direction, the displacement unit 1320 continues to drive the rotation unit 132 to displace, and the rotation unit 132 continues to drive the right-angle piece 131 to continue rotating, until the slow-descent unit 15 rotates to below the upper wall of the conveying tube 12, the right-angle piece 131 moves to the other side with the rotation unit 132 and rotates to a horizontal position on the vertical surface under the rotation unit 132, so that the sheet metal is placed flat on the conveying tube 12 again.

[0060] By changing the surface in this way, the side of the sheet metal is controlled, the range required during the surface change is reduced, and during the surface change, it can be better ensured that after the surface change, the sheet metal is still in the position before the surface change, which is beneficial to the subsequent adjustment of the laser head will not be too large.

[0061] The traction unit 16 includes a displacement plate 166 mounted on the motor 5 162. The displacement plate 166 is displaceably mounted in the displacement groove 165 of the support plate 161. A limiting hole 1662 is reserved in the center area of ​​the wall surface of the displacement plate 166 along the mounting direction. Variable plates 1663 are mounted on both sides of the limiting hole 1662. The variable plate 1663 is engaged with the disk 3 167. The disk 3 167 is engaged with the disk 4 168. The thickness of the disk 4 168 does not exceed that of the disk 3 167, which is beneficial for the disk 4 168 to be in the limiting hole 1662 and prevent the disk 4 168 from Cooperating with the variable plate 1663, the diameter direction is maintained stable only due to the limiting hole 1662, and the rotation is pulled only during the rotation of the disc three 167; the disc three 167 is connected to the power column one 145, and the disc four 168 is connected to the power column two 155. The power column one 145 and the power column two 155 are respectively installed on the supporting plate 161 via the rotating seat 169, and the transmission unit is installed under the supporting plate 161. The displacement part of the transmission unit is fixedly connected to the bottom of the displacement plate 166, the power column one 145 is connected to the lifting unit 14, and the power column two 155 is connected to the slow lowering unit 15.

[0062] When the transmission unit drives the displacement part to move, the traction displacement piece 166 moves along the displacement groove 165. During the displacement of the displacement piece 166, its change piece 1663 is applied to the disk three 167, and the traction disk three 167 and the power column one 145 rotate, thereby achieving the control of the rotation of the lifting unit 14; at this time, the displacement of the displacement piece 166 can ensure the stability of the diameter direction of the disk four 168 through the limiting hole 1662; the disk four 168 rotates counterclockwise due to the engagement with the disk three 167, that is, the rotation direction is different from that of the disk three 167, thereby achieving the control of the rotation of the slow-down unit 15. In this way, the traction unit 16 achieves the simultaneous control of the lifting unit 14 and the slow-down unit 15, avoiding the need to equip the lifting unit 14 and the slow-down unit 15 with independent control power, making the composition of the present invention simpler.

[0063] The transmission unit can use the motor five 162 and the threaded rod three 163, that is, the transmission unit includes the motor five 162 installed on the wall below the support plate 161 and the threaded rod three 163 with one end connected to the power end of the motor five 162, the supporting platform 1622 installed on the wall below the support plate 161 and screwed to the other end of the threaded rod three 163, and the variable platform two 164 installed on the threaded rod three 163, and the variable platform two 164 is connected to the bottom of the displacement plate 166.

[0064] The lifting unit 14 includes a bending lifting rod 142 and a power rod 143 connected to the bottom of the bending lifting rod 142, and the power rod 143 is connected to a power column 145. A flexible layer 144 is arranged on the bending lifting rod 142, which is beneficial for the flexible layer 144 to fit the sheet metal when the bending lifting rod 142 is applied to the sheet metal, so as to avoid causing wear of the sheet metal.

[0065] The slow-drop unit 15 includes a curved rotating bar 152, one end of which is connected to a power column 2 155, and the other end is provided with an auxiliary rotating part 154. The installation of the auxiliary rotating part 154 allows the curved rotating bar 152 to be used as a support point for slow-dropping during the bonding between the sheet metal and the curved rotating bar 152, and also allows the sheet metal to use the auxiliary rotating part 154 as a basic displacement during the bonding between the sheet metal and the slow-drop unit 15. Compared with the right-angle piece 131 having an undulating silicone pad 1312, the bonding between the right-angle piece 131 and the sheet metal is more stable.

[0066] According to the sheet metal replacement process of the traction unit 16, the lifting unit 14, and the slow-down unit 15, Figures 12 to 15 , Fig.17 The display has the following operation process:

[0067] In the initial stage, Fig.12 It is shown that the transverse surface of the right-angle piece 131 is transverse and fits under one side of the sheet metal;

[0068] Next, the disc 3 167 rotates under the influence of the variable plate 1663, so that the bending lifting rod 142 is applied to the sheet metal to lift the sheet metal from the other side to the top. At this time, the disc 4 168 rotates counterclockwise under the influence of the disc 3 167, so that the bending rotating bar 152 rotates from one side of the sheet metal to the top, that is, the left side. Fig.13 The sheet metal is shown in the opened state when it is lifted to a specific position by the bending lifting rod 142. At this time, the right-angle piece 131 moves along with the rotating unit 132 by a certain span, and the right-angle piece 131 rotates at a specific angle;

[0069] Then run, Fig.14 As shown in the figure, at this time, the sheet metal has been lifted up and just passed the vertical state, and tilted to the left to form an angle, and supported by the auxiliary rotating portion 154 of the bending rotating bar 152, that is, at this time, the bending lifting rod 142 and the bending rotating bar 152 rotate upward to the limit; at this time, the right-angle piece 131 rotates a larger angle, and moves a larger span with the rotating unit 132;

[0070] Next, the disc three 167 rotates counterclockwise due to the change piece 1663, and the disc four 168 rotates in a direction different from that of the disc three 167, and the bending lifting rod 142 and the bending rotating bar 152 are rotated downward respectively. At this time, the right-angle piece 131 continues to rotate at a larger angle, and its vertical surface slowly approaches the horizontal direction. At this time, the right-angle piece 131 follows the rotating unit 132 to get closer to the right, and the sheet metal continues to rotate downward with the bending rotating bar 152, tilting together. The bottom of the sheet metal is always in contact with the right-angle piece 131. Due to the existence of the rotating unit 132, the contact area between the bottom of the sheet metal and the right-angle piece 131 is maintained stable, and the sheet metal and the auxiliary rotating part 154 of the bending rotating bar 152 are smoothly fitted, which is beneficial to the movement of the auxiliary rotating part 154 along the short side of the sheet metal when the sheet metal is tilted;

[0071] Finally, Fig.17 It is shown that when the right-angle piece 131 moves to the right and the other side of the sheet metal is in the initial position, the right-angle piece 131 also rotates to the horizontal state from the previous vertical plane, and the bending lifting rod 142 and the bending rotating bar 152 are rotated under the conveying cylinder 12. The side of the sheet metal that falls obliquely is placed on the conveying cylinder 12 by the bending rotating bar 152 and the right-angle piece 131. The sheet metal is laid flat again after the face change, and this position is roughly the same as the position before the face change.

[0072] During the downward rotation of the bending rotating bar 152, after rotating to a specific angle, the sheet metal has a chance to move smoothly with the auxiliary rotating part 154, and the falling side of the sheet metal separates from the bending rotating bar 152 and falls directly toward the conveying cylinder 12, thus achieving the purpose of changing the surface. However, due to the falling distance, that is, during the separation, there is an angle between the sheet metal and the horizontal surface, so that after the falling side of the sheet metal falls, it may collide with the conveying cylinder 12 to cause wear, and there is also a chance that the position of the sheet metal after the surface change is offset, so a supporting bar 153 is installed on the bending rotating bar 152. Fig. 9 , Fig.10 The auxiliary rotating part 154 is installed on the supporting bar 153. The auxiliary rotating part 154 includes two or more rotating cylinders arranged in two rows. When the auxiliary rotating part 154 of the bending rotating bar 152 is in a horizontal layout state, the auxiliary rotating part 154 of the supporting bar 153 is also in a horizontal layout state. There is a set length between the auxiliary rotating part 154 of the supporting bar 153 and the auxiliary rotating part 154 of the bending rotating bar 152.

[0073] Therefore, during the falling process, the auxiliary rotating portion 154 of the supporting strip 153 can be separated from the sheet metal and the auxiliary rotating portion 154 of the bending rotating strip 152, and then the sheet metal is attached. Fig.16 The slow-drop unit 15 can maintain the slow drop of the sheet metal as much as possible during the drop process. The upper wall surface of the auxiliary rotating part 154 of the supporting bar 153 does not exceed the upper wall surface of the auxiliary rotating part 154 of the bending rotating bar 152, so that the sheet metal is supported by the auxiliary rotating part 154 of the bending rotating bar 152 during the vertical stage, so that the sheet metal is supported by the slow-drop unit 15, which is more than 1 / 2 of the sheet metal, which is beneficial to maintain the stability of the sheet metal during the drop.

[0074] The rotating unit 132 includes a rotating rod 133 mounted on two supporting plates 138. The rotating rod 133 is connected to the connecting area between the horizontal surface and the vertical surface of the right-angle plate 131. A disk 134 with a reserved tooth gap on the circumference is mounted on one end of the rotating rod 133. The disk 134 engages with the disk 2 136 with a reserved tooth gap on the circumference. The disk 2 136 is connected to the transmission rod 135 of the motor 3 137. The motor 3 137 is mounted on the displacement platform 139. The transmission rod 135 is mounted through the supporting plate 138. The displacement platform 139 is connected to the displacement part of the displacement unit 1320.

[0075] During the rotation, the motor 3 137 operates to drive the disk 2 136 to rotate via the transmission rod 135 , thereby pulling the disk 1 134 to rotate, thereby achieving the purpose of rotating the right-angle piece 131 via the rotating rod 133 .

[0076] The displacement unit 1320 is installed below the transport cylinder 12, and includes a limit frame 1323, and a second threaded rod 1324 installed in the limit frame 1323. One end of the second threaded rod 1324 is screwed to a wall surface at one end of the limit frame 1323, and the other end is connected to the power end of the fourth motor 1322. The fourth motor 1322 is connected to the other end of the limit frame 1323. The displacement platform 139 is installed on the second threaded rod 1324. The installation direction of the limit frame 1323 is the same as that of the transport cylinder 12.

[0077] During the required displacement, the motor 4 1322 pulls the threaded rod 2 1324 to rotate, thereby achieving the purpose of the displacement platform 139 being displaced along the limiting frame 1323 under the traction of the threaded rod 2 1324 .
