Description

Technical Field

[0001] The present application relates to the technical field of laser welding, and in particular to a common equipment for laser welding and zinc removal. Background Art

[0002] When ultra-high-strength galvanized steel sheets are currently used for roll forming, due to the galvanized surface, a suitable zinc removal mechanism is required during the welding process. On the one hand, this is to ensure welding stability and welding strength, and on the other hand, it can also adapt to galvanized sheets of different materials to avoid the different melting points of metallic zinc and steel during the welding process of galvanized steel sheets. When the steel melts, the zinc layer will vaporize, which will cause pores and spatter to form during welding, and the welding penetration and welding strength will be weakened. In order to ensure the strength of the welding, we use mechanical zinc removal methods to remove the zinc layer at the welding position during the rolling process to ensure that the steel is fully fused during the welding process to ensure the strength of the welding.

[0003] However, the existing tooling for removing zinc from galvanized steel has high cost, low replacement efficiency, poor stability, and limited versatility. Therefore, a common equipment for removing zinc from laser welding is proposed. Summary of the invention

[0006] Furthermore, the bottom opening size of the T-slot is larger than the upper opening size, so that the annular stopper is clamped at the bottom of the T-slot.

[0007] Furthermore, the upper end of the adjusting screw rod is threadedly connected with two nuts, and the nuts are M8 fixed nuts.

[0008] Furthermore, an arc-shaped notch is provided at the bottom of the adjusting screw rod, and the arc-shaped notch is engaged with the round hole plug.

[0009] Furthermore, a gasket is provided on one side of the standard cutter head, and the gasket is used to play a buffering role between the standard cutter head and the surface to be processed.

[0014] 1. The beneficial effects of the present application are as follows: by adjusting the rotation of the screw rod, the annular gear drives the standard blade head to adjust up and down, and the pressing force during zinc removal can be effectively adjusted, which not only ensures the quality and stability of zinc removal, but also avoids the serious wear of the scraper during zinc removal due to excessive pressing friction. By making standardized design changes to the standard blade head, the influence of the unstable zinc removal problem on welding and the difficulty of installation and debugging are solved, while the cost of use is greatly reduced, and the time and difficulty of replacing the standard blade head and standard blade particles are reduced. The pressing force is adjusted by this up and down adjustable pressing method to avoid uneven zinc removal or the phenomenon of inability to remove zinc from the galvanized steel surface, while also ensuring that the position and force of the scraper remain unchanged when it is replaced.

[0037] A common equipment for zinc removal by laser welding according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0038] Embodiment 1

[0039] like Figure 1-Figure 6 As shown, a common equipment for laser welding dezincification according to an embodiment of the present application includes a tool handle 1, a fixing plate 2 is provided at the upper end of the tool handle 1, a standard tool head 3 is movably installed inside the tool handle 1, and a standard tool particle 5 is installed at the lower end of the standard tool head 3.

[0040] The adjusting screw rod 7 passes through the fixing plate 2 and is inserted into the inner side of the circular stop 9. The circular stop 9 is located inside the T-slot 4 opened at the upper end of the standard cutter head 3. The bottom opening size of the T-slot 4 is larger than the upper opening size, so that the circular stop 9 is clamped at the bottom of the T-slot 4, thereby ensuring the stability of the circular stop 9 in the T-slot 4.

[0041] In order to strengthen the connection between the adjusting screw rod 7 and the circular ring stop 9, a round hole plug 10 is arranged inside the circular ring stop 9, and an arc-shaped notch is opened at the bottom of the adjusting screw rod 7. The arc-shaped notch is engaged with the round hole plug 10 and is fixed by the round hole plug 10 inside the circular ring stop 9.

[0042] A gasket 6 is provided on one side of the standard cutter head 3 , and the gasket 6 can play a buffering role between the standard cutter head 3 and the surface to be processed, thereby reducing the impact force and friction force during direct contact.

[0043] By rotating the adjusting screw 7, the adjusting screw 7 and the annular stop 9 are used to stretch or push down the standard blade 3, thereby adjusting the clamping force of the adjusting screw 7. The clamping force is adjusted by this up and down adjustable clamping method to avoid uneven or unremovable zinc removal on the surface of galvanized steel, while also ensuring that the position and force of the scraper remain unchanged when it is replaced.

[0044] Furthermore, two nuts 8 are threadedly connected to the upper end of the adjusting screw rod 7. When the adjusting screw rod 7 stops rotating, the two nuts 8 threadedly connected to the adjusting screw rod 7 are used to restrict the rotation, wherein the nuts 8 are M8 fixed nuts.

[0045] Embodiment 2

[0046] like Figures 7 to 10 As shown, the above embodiment uses the adjustment screw 7 to rotate to adjust the annular gear 9 to drive the standard cutter head 3 to move up and down, so as to achieve effective control of the clamping force during zinc removal. However, for application scenarios that require frequent adjustment of the clamping force, the adjustment screw 7 is not very flexible. Therefore, the second embodiment of the present application is shown.

[0047] First, a plug hole 11 is symmetrically provided at the upper end of the knife handle 1 , a mounting seat 16 is inserted into the plug hole 11 , and the mounting seat 16 is fixed inside the fixing plate 2 by bolts 15 .

[0048] A cylinder 17 is mounted on the mounting seat 16 , a bottom plate 18 is connected to the piston end of the cylinder 17 , and a positioning block 19 is arranged on the lower side of the bottom plate 18 .

[0049] Secondly, a second socket 12 is symmetrically provided at the upper end of the standard cutter head 3, and a plug rod 14 is inserted into the second socket 12. A connecting plate 13 is provided at the upper end of the plug rod 14. The positioning block 19 is plugged into the hole groove provided on the connecting plate 13 to fix the connecting plate 13 on the standard cutter head 3. The cylinder 17 is connected to the connecting plate 13. At this time, the standard cutter head 3 can be moved up and down by the extension and contraction of the cylinder 17, and the clamping force can be automatically adjusted. Of course, in order to make the connection between the cylinder 17 and the connecting plate 13 and between the connecting plate 13 and the standard cutter head 3 tighter, screws or other fasteners can be used to fix them to ensure that the standard cutter head 3 can move up and down smoothly.

[0050] Furthermore, a hollow rod 20 is provided on one side of the mounting seat 16, and a buffer rod 21 is slidably provided inside the hollow rod 20. One end of the buffer rod 21 is connected to the base plate 18, and limiting grooves 22 are provided on both sides of the hollow rod 20. The protrusions on both sides of the buffer rod 21 are slidably connected to the limiting grooves 22. When the cylinder 17 pushes the connecting plate 13, the buffer rod 21 is prompted to slide with the hollow rod 20, and the limiting grooves 22 ensure the stability of the buffer rod 21 during the sliding process to prevent displacement or jamming.

[0051] In addition, an elastic member 23 is provided in the hollow rod 20, and one end of the buffer rod 21 is connected to the elastic member 23. The elastic member 23 provides a buffering effect, reduces impact and vibration, and protects the equipment and workpiece. The elastic member 23 can adopt a shock absorbing device such as a shock absorber or a damper.

[0052] Of course, when the cylinder 17 is used to adjust the pressing force, the adjusting screw 7 needs to be disassembled.

[0053] A common equipment for laser welding zinc removal. Working principle: The equipment is installed as a whole on the lathe of the laser welding equipment. The standard cutter head 3 is adjusted up and down by adjusting the rotation of the screw rod 7. The pressing force during zinc removal can be effectively adjusted, which not only ensures the quality and stability of zinc removal, but also greatly reduces the cost of use, and reduces the time and difficulty of replacing the standard cutter head 3 and the standard cutter grain 5 by about 40%.

[0054] After removing the adjusting screw rod 7, use the bolt 15 to install the mounting seat 16 on the upper end of the shank 1, install the connecting plate 13 in turn, and then connect the piston end of the cylinder 17 to the connecting plate 13. The standard cutter head 3 can be adjusted up and down by extending and retracting the cylinder 17 to adjust its clamping force.

[0055] The above are only embodiments of the present application and are not intended to limit the scope of protection of the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0056] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
