Automatic longitudinal seam plate splicing and welding machine with slag cleaning mechanism

Abstract

This utility model relates to the field of welding equipment technology and discloses an automatic longitudinal seam splicing plate welding machine with a slag cleaning mechanism. It includes a chassis, on which a movable platform is fixedly connected. The movable platform is electrically connected to a main controller inside the chassis via a cable. A side frame is fixedly connected to one side of the movable platform, and a support is fixedly connected to one side of the side frame. A submerged arc welding head is fixedly connected inside the support. A slag-removing mechanism is provided on the side of the support opposite to the side frame. When welding the joint of two plates, excess welding material can be removed using a material suction device. Simultaneously, the side frame, in conjunction with the support, drives the slag-removing mechanism to move synchronously. This allows the drive wheel of the slag-removing mechanism to mesh with a gear rail, driving a rotating shaft to rotate. The cam on the outside of the rotating shaft then cyclically swings the force-bearing rod and the swing arm, causing the striking head at one end of the swing arm to strike the welding slag at the weld joint. This achieves slag removal simultaneously with welding completion, allowing the welding slag to be discharged and collected from the supporting grid through the slag discharge hopper.

Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to an automatic welding machine for longitudinal seam splicing plates with a slag cleaning mechanism. Background Technology

[0002] Longitudinal seam splicing is a welding process that splices multiple plates along their length, with the seam running longitudinally. It is commonly used for splicing large areas of metal materials such as steel plates and aluminum plates, and is also used when splicing small plates into large panels. During welding, the edges of the plates are first aligned and fixed, and then submerged arc welding, laser welding, or other methods are used to continuously weld along the longitudinal direction of the joint to ensure a firm and sealed joint. During submerged arc welding, the flux around the welding wire is melted by the arc heat. Part of it participates in the metallurgical reaction, while the other part solidifies into a slag shell on the weld surface. This shell can isolate the air, protect the high-temperature weld from oxidation, and slow down the cooling rate, making the weld structure more uniform. However, after welding, the slag shell will stick to the weld surface, especially when welding thick plates, where the slag shell is thicker. Although there are welding material suction devices, the slag shell has strong adhesion and is difficult for the equipment to completely remove. Therefore, after welding, it is necessary to manually knock it off with a hammer. In mass production, each weld seam must be manually knocked off one by one, which is slow and slows down the overall production progress. Utility Model Content

[0003] The purpose of this invention is to provide an automatic welding machine for longitudinal seam panels with a slag cleaning mechanism, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automatic longitudinal seam splicing plate welding machine with a slag cleaning mechanism includes a chassis. A movable platform is fixedly connected to the chassis. The movable platform is electrically connected to a main controller inside the chassis via a cable. A side frame is fixedly connected to one side of the movable platform. A bracket is fixedly connected to one side of the side frame. A submerged arc welding head is fixedly connected inside the bracket. A slag knocking mechanism is provided on the side of the bracket opposite to the side frame. The slag knocking mechanism includes an L-shaped carrier plate fixedly connected to one side of the bracket. A bearing is fixedly connected to the side of the L-shaped carrier plate opposite to the bracket. A rotating shaft is inserted into the bearing. A transmission wheel is fixedly connected to the outside of the rotating shaft. A swing arm is movably connected to one side of the bottom of the L-shaped carrier plate. A knocking head is fixedly connected to the end of the swing arm away from the L-shaped carrier plate.

[0005] As a further preferred embodiment of this utility model, a support grid is fixedly connected to one side of the chassis, and a slag discharge hopper is fixedly connected inside the support grid. The support grid supports the plate and can work with the slag discharge hopper to guide and collect the welding slag knocked down by the hammering head. The chassis located above the support grid is also fixedly connected to multiple pneumatic clamps. The pneumatic clamps are connected to the air compressor equipment inside the chassis through air pipes. The pneumatic clamps can press and fix the plate placed on the support grid to ensure the stability of welding.

[0006] As a further preferred embodiment of this utility model, a mounting plate is fixedly connected to one side of the top of the chassis. The mounting plate is Z-shaped, and a toothed rail is fixedly connected to one side of the mounting plate.

[0007] As a further preferred embodiment of this utility model, two fixed seats are fixedly connected to one side of the L-shaped carrier plate, and a connecting shaft is inserted between the two fixed seats. The connecting shaft provides conditions for the installation of the swing arm and enables the swing arm to rotate around the connecting shaft as the axis.

[0008] As a further preferred embodiment of this utility model, a gear is fixedly connected to the transmission wheel position behind the rotating shaft. The gear is also meshed with the toothed rail. When the moving platform drives the gear to move horizontally through the side frame, bracket, L-shaped carrier plate, shaft seat, and rotating shaft, the gear can rotate after meshing with the toothed rail, thereby driving the rotating shaft and transmission wheel to rotate.

[0009] As a further preferred embodiment of this utility model, a cam is fixedly connected to one side of the transmission wheel. After the transmission wheel drives the cam to rotate, it can create conditions for the reciprocating swing of the swing arm.

[0010] As a further preferred embodiment of this utility model, a connecting groove is provided at the end of the swing arm away from the striking head. A limiting block is fixedly connected to one end of the swing arm near the connecting groove. The swing arm is inserted into the connecting shaft and limited by a pin. A connecting block is spun into the connecting groove. A force-bearing rod is fixedly connected to one end of the connecting block. The end of the force-bearing rod away from the connecting block is inserted into the concave position on the outside of the cam. When the cam rotates, it can press down on the force-bearing rod, so that the force-bearing rod, through the connecting block and the limiting block, presses down on one end of the swing arm, thereby causing the swing arm to lift the striking head. When the convex part on the outside of the cam moves to the position of the force-bearing rod, one end of the swing arm swings down using the gravity of the striking head, so that the striking head strikes the weld slag at the weld seam and peels it off.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, when welding the joint of two plates, an suction device can be used to remove excess welding material. At the same time, the side frame and bracket drive the slag removal mechanism to move synchronously, so that the transmission wheel of the slag removal mechanism meshes with the gear rail and drives the rotating shaft to rotate. Then, the cam on the outside of the rotating shaft cyclically swings the force rod and the swing arm, so that the striking head at one end of the swing arm strikes the welding slag at the weld, realizing the slag removal operation at the same time as the welding is completed, so that the welding slag is discharged and collected from the supporting grid through the slag discharge hopper.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figures 1-6As shown, the present invention provides an automatic longitudinal seam splicing plate welding machine with a slag cleaning mechanism, including a machine housing 1. A mobile platform 2 is fixedly connected to the machine housing 1. The mobile platform 2 is electrically connected to the main controller inside the machine housing 1 via a cable. A side frame 3 is fixedly connected to one side of the mobile platform 2. A support 4 is fixedly connected to one side of the side frame 3. A submerged arc welding head 5 is fixedly connected inside the support 4. A slag knocking mechanism 6 is provided on the side of the support 4 opposite to the side frame 3. The slag knocking mechanism 6 includes an L-shaped carrier plate 7 fixedly connected to one side of the support 4. A bearing seat 8 is fixedly connected to the side of the L-shaped carrier plate 7 opposite to the support 4. A rotating shaft 9 is inserted into the bearing seat 8. A transmission wheel 10 is fixedly connected to the outside of the rotating shaft 9. A swing arm 11 is movably connected to one side of the bottom of the L-shaped carrier plate 7. A knocking head 12 is fixedly connected to the end of the swing arm 11 away from the L-shaped carrier plate 7.

[0016] like Figures 1-2 As shown, a support grid 14 is fixedly connected to one side of the chassis 1, and a slag discharge hopper 15 is fixedly connected inside the support grid 14. The support grid 14 supports the plate and can work with the slag discharge hopper 15 to guide and collect the welding slag knocked down by the hammer 12. The chassis 1 located above the support grid 14 is also fixedly connected to multiple pneumatic clamps 13. The pneumatic clamps 13 are connected to the air compressor equipment inside the chassis 1 through air pipes. The pneumatic clamps 13 can press and fix the plate placed on the support grid 14 to ensure the stability of welding.

[0017] like Figures 3-6As shown, a mounting plate 16 is fixedly connected to one side of the top of the chassis 1. The mounting plate 16 is Z-shaped, and a gear rail 17 is fixedly connected to one side of the mounting plate 16. Two fixed seats 18 are fixedly connected to one side of the L-shaped carrier plate 7. A connecting shaft 19 is inserted between the two fixed seats 18. The connecting shaft 19 provides the conditions for the installation of the swing arm 11 and enables the swing arm 11 to rotate around the connecting shaft 19. A gear 25 is fixedly connected to the rear drive wheel 10 of the rotating shaft 9. The gear 25 is also meshed with the gear rail 17. When the moving platform 2 drives the gear 25 to move horizontally through the side frame 3, bracket 4, L-shaped carrier plate 7, bearing seat 8, and rotating shaft 9, the gear 25 can mesh with the gear rail 17 and rotate, thereby driving the rotating shaft 9 and the drive wheel 10 to rotate. A cam 20 is fixedly connected to one side of the drive wheel 10. After the drive wheel 10 drives the cam 20 to rotate, it can provide the swing arm 11 with the drive wheel 11. The reciprocating swing of the swing arm 11 creates conditions for the connecting groove 21 to be opened at the end of the swing arm 11 away from the striking head 12. A limiting block 22 is fixedly connected to one end of the swing arm 11 near the connecting groove 21. The swing arm 11 is inserted into the connecting shaft 19 and limited by a pin. A connecting block 24 is axially connected in the connecting groove 21. A force rod 23 is fixedly connected to one end of the connecting block 24. The end of the force rod 23 away from the connecting block 24 is inserted into the concave position on the outside of the cam 20. When the cam 20 rotates, it can press down on the force rod 23, so that the force rod 23, through the connecting block 24 and the limiting block 22, presses down on one end of the swing arm 11, which can make the swing arm 11 lift the striking head 12. When the convex part on the outside of the cam 20 moves to the position of the force rod 23, one end of the swing arm 11 swings down with the weight of the striking head 12, so that the striking head 12 strikes the weld slag at the weld and peels it off.

[0018] It should be noted that this utility model is an automatic longitudinal seam splicing plate welding machine with a slag cleaning mechanism. During operation, the plate is first placed on the supporting grid 14. The pneumatic clamp 13, driven by the air compressor inside the machine housing 1, presses and fixes the plate. The moving platform 2, controlled by the main controller inside the machine housing 1, moves the side frame 3 and the support 4. The submerged arc welding head 5 on the support 4 then welds along the longitudinal seam. Simultaneously, a material suction mechanism is set on one side of the support 4 to collect excess welding material after welding. The striking head 12 maintains a certain distance from the initial position of the plate, allowing welding to be completed at the corresponding position on the plate and the welding material to be removed. After the support 4 moves the L-shaped carrier plate 7, the rotating shaft 9 inside the bearing seat 8 moves accordingly. Its end gear 25 meshes with the gear rail 17 on the mounting plate 16. The rotation of the gear 25 drives the rotating shaft 9 and the transmission wheel 10 to rotate. The cam 20 on one side of the transmission wheel 10 rotates accordingly. When wheel 20 rotates, its convex and concave parts alternately act on the force rod 23. That is, the swing arm 11 swings with the connecting shaft 19 between the fixed seats 18 as the fulcrum. When cam 20 presses down the force rod 23, swing arm 11 lifts the striking head 12. After the convex part turns away, the striking head 12 falls down to strike the welding slag. When removing the plate, the plate can be removed at an angle, so that the detached welding slag falls into the slag discharge hopper 15 through the support grid 14 for collection, realizing the simultaneous completion of welding and slag removal. When the moving platform 2 drives the slag knocking mechanism 6 to reset and move through the side frame 3 and bracket 4, gear 25 will still mesh with the gear rail 17 and rotate in the opposite direction. At this time, gear 25 drives the rotating shaft 9 to rotate in the opposite direction with the transmission wheel 10 and cam 20, so that the convex part on the outside of cam 20 pushes the force rod 23 upward, and makes the force rod 23 rotate around the fixed shaft at the center of the connecting block 24, thereby ensuring that the slag knocking mechanism 6 follows the reset movement of bracket 4.
