Description

Technical Field

[0001] The utility model relates to the technical field of welding devices, and more specifically, to a welding device for steel. Background Art

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are three main welding methods: fusion welding, brazing and pressure welding. Welded products are lighter than riveted parts, castings and forgings. For transportation vehicles, they can reduce their own weight and save energy. In addition, the welded products have better sealing properties and are suitable for manufacturing various containers with higher economic benefits.

[0003] When welding steel, operators often use welding devices to weld two pieces of steel together by rubbing the welding surfaces of the steel to ensure the strength of the weld of the steel. In actual use, although the existing welding devices have basic welding functions, during the welding process, part of the melted solder will accumulate on the outer surface of the steel. This part of the solder is generally knocked off manually, which increases the labor intensity of the operators, so it needs to be improved. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 5 As shown, the utility model provides a steel welding device, including:

[0027] A welding bed 1, a mounting plate 2 is fixedly connected to the rear side of the upper surface of the welding bed 1, and a limiting plate 3 is fixedly connected to the middle of the upper surface of the welding bed 1;

[0028] A waste box 4, the outer surface of the waste box 4 and the inner surface of the limiting plate 3 are movably connected;

[0029] A material removal mechanism, which is arranged on the right side of the mounting plate 2;

[0030] Among them, the material removal mechanism includes a No. 1 motor 5, the lower end of the No. 1 motor 5 is fixedly installed in the middle of the right side of the upper surface of the welding bed 1, the other end of the output shaft of the No. 1 motor 5 is fixedly sleeved with a round shaft 6, the front end of the outer surface of the round shaft 6 is fixedly sleeved with a connecting plate 7, the outer surface of the other end of the connecting plate 7 is movably connected with a moving block 8, and the middle part of the left surface of the moving block 8 is fixedly connected with a scraper plate 9, the left end of the scraper plate 9 penetrates the mounting plate 2 and extends to the left side of the mounting plate 2, and the left end of the scraper plate 9 scrapes off excess molten solder on the outer surface of the steel.

[0031] When the steel rotates, the operation of motor No. 1 5 will cause the circular shaft 6 to drive the connecting plate 7 to start rotating. At this time, the outer surface of the other end of the connecting plate 7 will push the inner surface of the moving block 8, so that the moving block 8 as a whole starts to move to the left along the inner surface of the mounting plate 2. Finally, the left end of the scraper plate 9 will contact the outer surface of the steel, so that the excess solder on the outer surface of the steel is scraped off by the lower end of the scraper plate 9 and falls into the waste box 4.

[0032] Among them, a fixed seat 11 is fixedly connected to the right side of the upper surface of the welding bed 1, a movable groove 10 is opened on the left side of the upper surface of the welding bed 1, and a movable seat 12 is movably connected to the inner surface of the movable groove 10. The right side of the inner surface of the fixed seat 11 and the left side of the inner surface of the movable seat 12 are movably installed with an installation box 13, and the right side of the inner surface of the movable seat 12 is fixedly connected to a fixed plate 25.

[0033] The leftward movement of the movable seat 12 causes the two pieces of steel to be pressed against each other, thus facilitating the friction welding.

[0034] Among them, clamping grooves 14 are opened all around the outer surface of the installation box 13, and an arc-shaped clamping plate 15 is movably installed on the inner surface of the clamping groove 14. The outer surface of the arc-shaped clamping plate 15 is fixedly connected to a spring 16 located inside the installation box 13, and the other end of the spring 16 is fixedly connected to the inner surface of the installation box 13.

[0035] The design of the four arc-shaped clamping plates 15 enables the steel material to be clamped at the current position, thus ensuring stable friction welding.

[0036] The inner surface of the arc-shaped clamping plate 15 is hinged with a connecting block 17 located inside the installation box 13 , and the other end of the connecting block 17 is hinged with a pressing plate 18 .

[0037] The left and right movement of the pressing plate 18 causes the connecting block 17 to pull the four arc-shaped clamping plates 15 , so that the four arc-shaped clamping plates 15 move centripetally along the inner surface of the clamping groove 14 and finally clamp the steel material.

[0038] Among them, the outer surface of the pressure plate 18 is fixedly connected to the pneumatic cylinder 19 located outside the installation box 13, the outer surface of the pneumatic cylinder 19 is fixedly connected to the fixing box 20, the other end of the fixing box 20 is fixedly connected to the outer surface of the installation box 13, and the right side of the outer surface of the fixing box 20 is fixedly socketed with the inner surface of the fixing plate 25.

[0039] When the pneumatic cylinder 19 is in operation, the pressing plate 18 will start to move left and right.

[0040] Among them, a No. 2 motor 21 located on the front side of the fixed box 20 is fixedly installed in the middle of the left surface of the fixed seat 11, and a rotating shaft 22 is fixedly sleeved on the other end of the output shaft of the No. 2 motor 21. A rotating disk 23 is fixedly sleeved on the outer surface of the rotating shaft 22. Connecting rods 24 are fixedly connected around the right surface of the rotating disk 23, and the right end of the connecting rod 24 is fixedly connected to the left surface of the fixed box 20.

[0041] The operation of the second motor 21 causes the rotating shaft 22 to drive the rotating disk 23 to start rotating, which causes the fixing box 20 as a whole to drive the steel material to start rotating together, so that the two steel materials generate friction and are finally welded together through friction heat.

[0042] Among them, a No. 3 motor 26 is fixedly installed in the middle of the top of the right surface of the welding bed 1, and a lead screw 27 is fixedly sleeved on the other end of the output shaft of the No. 3 motor 26. The left end of the lead screw 27 passes through the right surface of the welding bed 1 and extends to the interior of the welding bed 1. The outer surface of the lead screw 27 and the inner surface of the movable seat 12 are threadedly sleeved.

[0043] The operation of the third motor 26 will cause the lead screw 27 to start rotating, and the moving seat 12 will move to the left along the inner surface of the moving groove 10 driven by the lead screw 27 .

[0044] The working principle and use process of this utility model:

[0045] First, the operator puts the two steel materials between the arc-shaped clamps 15 respectively and then starts the pneumatic cylinder 19. The operation of the two pneumatic cylinders 19 causes the two pressure plates 18 to be pulled and start to move away from each other. At this time, the other end of the eight-connecting block 17 will pull the eight arc-shaped clamps 15 respectively and make the eight arc-shaped clamps 15 start to move toward the center of the installation box 13. During this process, the eight arc-shaped clamps 15 will start to move toward the outer surface of the steel materials under the limitation of the clamping groove 14. Finally, the inner surfaces of the eight arc-shaped clamps 15 clamp the outer surfaces of the two steel materials respectively, thereby fixing the two steel materials.

[0046] After the fixation is completed, the operator then starts the No. 2 motor 21. The operation of the No. 2 motor 21 will cause the rotating shaft 22 to drive the rotating disk 23 to start rotating. The fixing box 20 and the mounting box 13 located inside the fixing seat 11 will rotate as a whole under the drive of the rotating disk 23, which causes the steel fixed on the right side of the fixing seat 11 to start rotating together, which causes friction between the welding surfaces of the two steels and eventually welds them together. Then the operator starts the No. 1 motor 5. The operation of the No. 1 motor 5 will cause the circular shaft 6 to drive the connecting plate 7 to start rotating. At this time, the outer surface of the other end of the connecting plate 7 will push the inner surface of the moving block 8. Under the limit of the mounting plate 2, the moving block 8 starts to drive the scraper plate 9 to move to the left, and finally the left end of the scraper plate 9 will contact the outer surface of the steel. Due to the rotation of the steel, the lower end of the scraper plate 9 will scrape off the excess molten solder on the outer surface of the steel. After being scraped off, these solders will fall into the waste box 4, avoiding the manual knocking out of the excess solder on the outer surface of the steel.
