Description

Technical Field

[0001] The utility model relates to the technical field of steel plate welding, in particular to a ceramic liner tightening device for welding. Background Art

[0002] Pad welding is a widely used welding method in the field of steel plate butt welding. Before the butt welding of steel plates, in order to make the misalignment of the weld assembly within the control range and control the deformation during the welding process, the assembled weld needs to be fixed. In the prior art, welding card codes are usually used to fix the assembly weld. After the butt welding is completed, the welding card codes and ceramic pads need to be cut and removed, and the weld and card code welding positions need to be polished and repaired. However, card code welding has two main defects: 1. A lot of equipment work needs to be done before the welding construction begins, and the welding of the card codes also requires skilled technical workers. Moreover, a lot of flaws are left after the removal of the welding card codes. Flame cutting, carbon planing, polishing and repair welding are required later, resulting in low welding construction efficiency and high construction costs; 2. After the ordinary welding card codes are removed, it is easy to cause a certain degree of damage to the steel plate, and the degree of reuse of the welding card codes is low after use, resulting in waste of materials.

[0003] In order to solve the above-mentioned problems of code welding, the invention patent with the authorization announcement number CN104741858 B proposes a CO2 butt seam gasket welding codeless welding tool, which uses a clamping structure to clamp the upper part of the welding parts, and uses a clamping structure to clamp the lower part of the welding parts, and fixes the welding ceramic gasket to the weld of the two welding parts. This welding tool solves the problems of existing code welding, but its application range is limited to horizontal butt welding of flat steel plates. When the steel plate has a surface curvature or requires large angle or right-angle butt welding, the above-mentioned codeless welding tool will not be applicable, and its application is relatively limited.

[0032] In order to facilitate further understanding of the present invention, the ceramic backing tightening device for welding of the present invention is described in detail below with reference to different embodiments.

[0033] Example 1: Figure 1 As shown, in embodiment 1, the crossbeam 1 is a horizontally arranged integrated beam frame 11, and the welding ceramic liner tightening device of the integrated beam frame 11 is suitable for Figure 1 Butt welding of flat steel plates as shown, Figure 3 The steel plate arc internal butt weld shown, and Figure 4In this embodiment 1, the integrated beam frame 11 does not provide angle change, and the angle adjustment of the steel plate support fixing mechanism 3 at both ends of the integrated beam frame 11 can be achieved. Figure 1 The flat plate butt welding shown is switched to Figure 3 The steel plate arc butt welding shown or Figure 4 The steel plate shown is butt welded with an arc outside. Figure 1 In the flat steel plate butt welding state shown, the steel plate support fixing mechanisms 3 at both ends of the integrated beam frame 11 remain perpendicular to the integrated beam frame 11, that is, no angle adjustment is performed. Figure 3 When the steel plate arc-shaped inner butt welding is performed, the steel plate support fixing mechanisms 3 at both ends are rotated toward each other at an angle, and the steel plate arc-shaped inner butt welding can be applied. Figure 4 When the steel plate arc-shaped external butt welding is performed, the steel plate support fixing mechanisms 3 at both ends are relatively rotated away from each other by an angle, which can be applied to the steel plate arc-shaped external butt welding. Figure 1 Butt welding of flat steel plates as shown, Figure 3 The steel plate arc butt welding and Figure 4 When the steel plates are arc-shaped butt-welded as shown, the ceramic liner used in the device is a first-type ceramic liner 200 with a plane in the middle of the bottom. Correspondingly, the support plate in the tightening support mechanism 2 is a flat support plate 21, which is matched with the first-type ceramic liner 200.

[0034] Example 2: Figure 2 As shown, in embodiment 2, the crossbeam 1 is a split crossbeam with a changeable support angle, specifically, it comprises two crossbeam units 11a of the same structure, the opposite ends of the two crossbeam units 11a are rotatably hinged and fixed, and an angle positioning mechanism is provided at the hinge. The ceramic liner tightening device for welding the split crossbeam is suitable for Figure 2 Butt welding of flat steel plates as shown, Figure 3 The steel plate arc butt welding shown Figure 4 The steel plate arc external butt welding shown, Figure 5 The large angle steel plate butt welding shown and Figure 6 The right angle butt weld shown. Figure 2 Butt welding of flat steel plates as shown, Figure 3 The steel plate arc butt welding and Figure 4When the steel plate is butt welded in an arc shape, the ceramic liner used in the device is a first type ceramic liner 200 with a plane at the bottom middle section, and accordingly, the support plate in the top support mechanism 2 is a flat support plate 21, which is matched with the first type ceramic liner 200. In the embodiment of the utility model, the angle positioning mechanism is a fastening pin 12, and the hinge angle between the two beam units 11a can be adjusted and fixed by manual adjustment.

[0035] When needed to apply Figure 5 The large angle steel plate butt welding shown and Figure 6 When the right-angle butt welding is performed, the angle positioning mechanism is used to adjust the hinge angle between the two beam units 11a, which can be applied to Figure 5 and Figure 6 Two butt welding situations are shown.

[0036] Specifically, in Figure 5 In the large-angle steel plate butt welding state shown in FIG. 1 , the hinge angle between the two beam units 11a corresponds to the large angle of the steel plate butt welding. Figure 5 As shown in FIG. 1 , when the bottom of the steel plate to be welded is a plane, the steel plate supporting and fixing mechanism 3 at the end of the beam unit 11a remains perpendicular to the corresponding beam unit 11a. Figure 5 In the large-angle steel plate butt welding state shown in the figure, the ceramic liner used in the device is a second-type ceramic liner 200a with an obtuse-angle structure at the bottom, and the support plate in the support mechanism 2 is an obtuse-angle support plate 21a. The obtuse-angle structure at the bottom of the second-type ceramic liner 200a is matched with the obtuse-angle structure on the upper surface of the obtuse-angle support plate 21a, and the two are in close contact, and the second-type ceramic liner 200a is supported by the matching obtuse-angle support plate 21a. Figure 5 In the large angle steel plate butt welding shown in the figure, when the steel plate to be welded is Figure 3 In the arc-shaped inner butt welding shown, by rotating the steel plate support fixing mechanisms 3 at the ends of the two beam units 11a toward each other by an angle, the arc-shaped inner butt welding in the large-angle steel plate butt welding can be applied. Figure 5 In the large angle steel plate butt welding shown in the figure, when the steel plate to be welded is Figure 4 During the arc-shaped external butt welding shown, by rotating the steel plate supporting and fixing mechanisms 3 at the ends of the two beam units 11a away from each other by an angle, it can be applied to the arc-shaped external butt welding in large-angle steel plate butt welding.

[0037] Specifically, in Figure 6 In the right-angle butt welding state shown, the hinge angle between the two beam units 11a corresponds to the right angle of the steel plate butt welding, that is, it is a right-angle hinge. Figure 6As shown in FIG. 1 , when the bottom of the steel plate to be welded is a plane, the steel plate supporting and fixing mechanism 3 at the end of the beam unit 11a remains perpendicular to the corresponding beam unit 11a. Figure 6 In the right-angle butt welding state shown, the ceramic liner used in the device is the third type ceramic liner 200b, and the support plate in the top support mechanism 2 is a right-angle support plate 21b, and the third type ceramic liner 200b is supported by the right-angle support plate 21b of the matching model. Figure 6 In the right-angle butt welding shown in the figure, when the steel plates to be welded are Figure 3 In the arc-shaped inner butt welding shown, the steel plate support fixing mechanisms 3 at the ends of the two beam units 11a are rotated toward each other by an angle, so that the arc-shaped inner butt welding in the right-angle butt welding can be applied. Figure 6 In the right-angle butt welding shown in the figure, when the steel plates to be welded are Figure 4 During the arc-shaped external butt welding shown, the steel plate supporting and fixing mechanisms 3 at the ends of the two beam units 11a are rotated away from each other by an angle, so that the arc-shaped external butt welding in the right-angle butt welding can be applied.

[0038] Figure 7 The figure shows the normal post-welding state of steel plate butt welding. Figure 8 The picture shows the abnormal butt welding state of the steel plate with ceramic liner. Figure 7 In the figure, the bottom height and shape of the welding part 300 are the inner arc shape and height of the ceramic liner in the tight state, which is shown as the normal excess height part 310. When the ceramic liner is loose, a welding leak part 320 appears at the bottom of the welding part 300. The welding leak part 320 has a surplus and height that exceeds the normal excess height part 310, which is an unqualified welding.

[0039] To sum up, the ceramic gasket tightening device for welding of the utility model can tighten the ceramic gasket under the weld of the butt-welded steel plate from below through the tightening support mechanism, so as to prevent the ceramic gasket from falling off and causing problems such as excessive excess height on the back of the welding part and welding leakage. The steel plate supporting and fixing mechanism is rotatably connected to the end of the beam through a damping shaft, and the angle of the steel plate supporting and fixing mechanism can be flexibly adjusted and positioned, so that it can be applied to steel plates with different welding angles, with a wide range of applications.
