Description

Technical Field

[0001] The present application relates to the technical field of plate butt welding, and in particular to a plate butt welding side leveling device. Background Art

[0002] Plate butt welding is the process of welding two separate plates into an integral structure to increase the area of ​​a single plate. It is usually used when the existing equipment is limited in the size of the plates to be processed and a large area of ​​plate is required.

[0003] At present, plasma welding machines are used for plate butt welding. The structure is as shown in the attached manual. Figure 1 As shown in FIG. 1 , the butt welding machine comprises a welding platform for placing the butt welding plates, a pressing plate for pressing the plates on each side against the welding platform, and a welding gun that can be adjusted to align with the plates to be butt welded. When the plates are butt welded, the plates to be butt welded are placed on the welding platforms on both sides with gaps (the reserved gaps are to avoid welding the plates on the welding platform during welding) (such as Figure 2 As shown), the welding sides of the plates on both sides are then driven to approach each other on the welding platform (usually driving balls are evenly distributed on the welding platform to facilitate the driving of the plates, which is not shown in the figure). After the sides of the plates on both sides are close to each other, the pressing plate drives the pressing plate to contact the plates through the driving cylinder at its top, and presses the plates onto the welding platform. Then the welding gun is driven by the driving mechanism (including horizontal slide rails and vertical slide rails) to approach the sides of the butt-welded plates, and under the sliding of the horizontal slide rail, the welding gun realizes continuous welding operation along the length direction of the sides of the plates.

[0004] At present, during the process of sheet metal processing and forming, the side of the sheet metal will be subjected to the rolling force, the high temperature of heat treatment, etc., and there will be different degrees of bending (warping) state (such as Figure 4-5 As shown in the figure, the pressing plate cannot completely cover the side of the plate for pressing, and it will block the welding operation on the side of the plate. Therefore, the warping of the plate will affect the flatness of the welded plate, causing the side of the plate to be misaligned after welding the left and right plates (forming a step surface), affecting the surface flatness of the plate after welding. Summary of the invention

[0005] In response to the above-mentioned problems, the present application aims to provide a side leveling device for plate butt welding, which can make the side end surface of the warped edge horizontally aligned with the side edge of the plate on the opposite side, thereby improving the flatness of the welding and solving the current problem of the flatness of the entire plate surface after butt welding being affected by the warping of the plate during plate processing.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is as follows: a side leveling device for plate butt welding, the plate butt welding uses a plasma butt welding machine, the butt welding machine has a welding platform for placing the butt welding plate, a pressing plate for pressing each side of the plate against the welding platform, and a welding gun that can be adjusted to align with the butt welding plate, characterized in that: the side leveling device is a driving mechanism that is arranged on the pressing plate and close to the side of the plate to drive the side of the plate to deform, and an auxiliary driving mechanism is also arranged on the welding platform in the opposite adjustment direction of the driving mechanism.

[0007] Preferably, the driving mechanism is a first adjusting screw rod that passes through the pressure plate near the side edge of the plate, and the end of the first adjusting screw rod that abuts against the plate is configured as a spherical structure.

[0008] Preferably, the auxiliary driving mechanism is a second adjusting screw having the same structure as the first adjusting screw and is disposed on the welding platform and close to the side edge of the plate.

[0009] Preferably, adjustment holes for passing the second adjustment screw are provided at intervals on the welding platform.

[0010] The beneficial effect of the present application is that the side leveling device, through the cooperation of the driving mechanism and the auxiliary driving mechanism, under the support of the auxiliary driving mechanism, drives the warped edge to bend downward in the opposite direction through the driving mechanism, so that the side end surface of the warped edge can be horizontally aligned with the side edge of the plate on the opposite side, thereby improving the flatness of the welding and solving the current problem of affecting the surface flatness of the entire plate after welding due to the warping of the plate during processing.

[0020] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0021] See attached Figures 1 to 8 The plate butt welding side leveling device shown in the figure uses a plasma butt welding machine for plate butt welding, and the butt welding machine has a welding platform 1 for placing the butt welding plate, a pressing plate 2 for pressing each side of the plate against the welding platform 1, and a welding gun 3 that can be adjusted to align with the butt welding plate. At present, when the plate butt welding operation is performed, the butt welding plates are placed on the welding platforms on both sides respectively, and then the welding sides of the plates on both sides are driven to approach each other on the welding platform, and then the welding gun is driven by a driving mechanism to approach the side of the butt welding plate, and under the sliding of the horizontal slide rail, the welding gun realizes continuous welding operation along the length direction of the side of the plate.

[0022] In order to solve the problem that the flatness of the welded plate is affected by the warping formed during the plate processing, the present application is provided with a side leveling device, which is a driving mechanism arranged on the pressing plate 2 and close to the side of the plate to drive the side of the plate to deform, such as Figure 5 As shown in the figure, the warping direction of the side edge of the plate is upward, and the drive mechanism drives the warping edge to deform downward ( Figure 7 As shown), the warped edge is gradually deformed to a state where it is horizontally aligned with the side edge of the plate on the opposite side, and then the side edges of the plate can be butt-welded to ensure the flatness of the plate after welding.

[0023] Since the surface of the welding platform 1 is a horizontal plane, when the warping edge is driven to deform by the driving mechanism, the bending stress of the bridge edge still cannot make it horizontally aligned with the side edge of the plate on the opposite side. Therefore, in order to solve this problem, Figure 7-8 As shown, the welding platform 1 is also provided with an auxiliary driving mechanism in the opposite direction to the driving mechanism, and the auxiliary driving mechanism cooperates with the driving mechanism as shown in FIG. Figure 8 As shown by the middle arrow, under the support of the auxiliary driving mechanism, the driving mechanism drives the warped edge to bend downward in the opposite direction, so that the side end surface of the warped edge can be horizontally aligned with the side edge of the plate on the opposite side, thereby improving the flatness of the welding.

[0024] Specifically, Figure 6-8As shown, the driving mechanism is a first adjusting screw 4 which is arranged on the side of the pressing plate 2 near the plate, and the end of the first adjusting screw 4 which abuts against the plate is set as a spherical structure. Figure 7-8 As shown, by rotating the first adjusting bolt 4 so that it contacts the warped edge, the warped edge is forced to bend downward (as shown by arrow a in the figure), so that the warped edge can be aligned horizontally with the side edge of the opposite plate, and then the welding operation is performed by a welding gun. The end surface of the spherical structure of the first adjusting bolt 4 facilitates the deformation and rotation of the warped edge at the first adjusting bolt 4.

[0025] In order to eliminate the bending stress of the warped edge, Figure 7-8 As shown in the figure, the auxiliary driving mechanism is a second adjusting screw 5 which is provided on the welding platform 1 and near the side edge of the plate and has the same structure as the first adjusting screw 4. The second adjusting screw 5 applies a force upward from the bottom surface of the warped edge of the plate (as shown by arrow b in the figure), while the first adjusting screw 4 exerts a force opposite to and staggered to the force of the second adjusting screw 5, thereby Figure 8 As shown by the middle arrow, the warped edge is driven to bend downward, thereby effectively eliminating the bending stress of the warped edge and making its side end face gradually horizontally aligned with the side edge of the plate on the opposite side, so that the plate can be butt-welded.

[0026] Regarding the warping direction of the side edge of the plate, the above description takes the upward warping as an example. There is also a downward warping structure. Therefore, in order to realize deformation drive for the downward warping, Figure 7 As shown, adjustment holes 1a for passing the second adjustment screw 5 are provided at intervals on the welding platform 1. By passing the second adjustment screw 5 through different adjustment holes 1a, the position of the second adjustment screw 5 and the first adjustment screw 4 is changed, thereby achieving the deformation driving effect on the downward warped edge, and also achieving the above-mentioned driving of the downward warped edge to be in a horizontal alignment with the side edge of the plate on the opposite side, which is convenient for the butt welding connection operation.

[0027] The principle of the present application is: when performing butt welding connection of plates, the plates to be butt welded are placed on the welding platforms 1 on both sides respectively, and then the welding sides of the plates on both sides are driven to approach each other on the welding platform 1. After approaching, if there is warping on the side of the plate, the first adjusting screw 4 and the second adjusting screw 5 are driven to abut against the warping edge of the plate, and the warping edge is driven to bend and deform in the opposite direction, so that the side end face of the warping edge is horizontally corresponding to the side edge of the plate on the opposite side, and then the butt welding connection operation of the plate is realized by driving the welding gun downward and moving horizontally along the length direction of the side edge of the plate.

[0028] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
