Description

Technical Field

[0001] This utility model relates to a steel cylinder welding device, and more particularly to a welding device for handles and bases of refillable steel cylinders. Background Technology

[0002] Steel cylinders are generally used to fill compressed gas. Their handles are welded by hand-held welding guns, while the main body is produced by forming sheet material into a cylindrical shape, pre-embedding welding wire inside, and then sending it to a brazing furnace for high-temperature treatment to melt the welding wire. After cooling, the cylindrical bodies are welded together.

[0003] Currently, the welding lines for these two parts are set separately during welding, which results in an extra material transfer step in the middle. The connection between the two steps is slow, affecting welding efficiency. Utility Model Content

[0004] This invention addresses the problem of low efficiency caused by welding lines mentioned in the background art. The technical problem to be solved by this invention is to provide a welding device for handles and bases of refillable steel cylinders.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A welding device for handles and bases of refillable steel cylinders includes a machine base. A welding table is located at the front of the machine base, with a handheld welding gun at the welding table. A high-temperature resistant conveyor line is located in the middle of the machine base, and a brazing furnace is located at part of the conveyor line. A metal mesh bag is installed on the high-temperature resistant conveyor line, with the highest horizontal bar at the rear of the metal mesh bag being lower than the highest horizontal bar at the front. A feeding device is located at the rear of the machine base. The feeding device includes a gantry frame, a rotating frame mounted on the gantry frame and driven to rotate by a rotary cylinder, a lifting sling on one side of the rotating frame, and a sliding table slidably mounted on the other side of the rotating frame. Two hooks are mounted on the sliding table, arranged side-by-side with the front hook higher than the rear hook. Each hook includes a pressing cylinder, a mounting base, and a zigzag hook body hinged to the mounting base. The output end of the pressing cylinder is installed through and has a U-shaped structure with an opening facing downwards. The mounting base has a clearance opening for the hook body to rotate, and the hook body rests against the opening of the U-shaped structure. When the pressing cylinder presses down, it drives the hook body to rotate upwards; when the pressing cylinder retracts, the hook body rotates downwards and disengages.

[0006] Preferably, there are reserved placement areas on the left and right sides of the rear of the machine, and the hook is located above the placement area after the rotating frame rotates.

[0007] Preferably, the brazing furnace includes a furnace box, a burner installed inside the furnace box, and a gas cylinder installed outside the furnace box. The gas cylinder supplies gas to the burner to generate high temperature inside the brazing furnace to melt the welding rods preset inside the cylinder and complete the welding. A high-temperature resistant conveyor line passes through the brazing furnace.

[0008] As a preferred option, the high-temperature resistant conveyor line is a stainless steel mesh belt conveyor, which is driven by a motor with a drive wheel.

[0009] Preferably, the lifting sling includes a lifting motor, a cable seat located at the output end of the lifting motor, a cable fixed to the cable seat, and two fixed pulleys located at the top of the rotating frame. The cable passes around the two fixed pulleys and is fixedly connected to the slide table.

[0010] Compared with the prior art, this utility model has the following advantages: The handle is welded to the front end of the bottle body. After the handle is welded by a handheld welding gun operated manually, welding wire is installed, and the cylinder is placed directly in a mesh bag and transported to the brazing furnace through a chain conveyor to heat and melt the welding wire at high temperature. After cooling, the bottle body is welded and then transported out. After being transported out, the front and back sides of the mesh bag are hooked by two hooks. After being hooked, it is lifted by a sling and rotated to one side of the machine and lowered by a rotating frame. After being lowered, it is manually removed after the temperature drops, which greatly improves the overall efficiency. Attached Figure Description

[0015] This embodiment mainly describes the title of the welding device for the handle and base of the refillable steel cylinder, as follows: like Figure 1-4 As shown, the refillable cylinder handle and base welding device includes a machine base 10. A welding table is located at the front of the machine base 10, and a handheld welding gun is installed at the welding table. A high-temperature resistant conveyor line 30 is located in the middle of the machine base 10, and a brazing furnace 20 is installed at part of the high-temperature resistant conveyor line 30. A metal mesh bag is installed on the high-temperature resistant conveyor line 30, and the highest horizontal bar at the rear of the metal mesh bag is lower than the highest horizontal bar at the front. A feeding device 50 is located at the rear of the machine base 10. The feeding device 50 includes a gantry frame 501, a rotating frame 503 mounted on the gantry frame 501 and driven to rotate by a rotating cylinder 502, and a lifting sling located on one side of the rotating frame 503. A sliding table is slidably mounted on the other side of the rotating frame 503. The sliding table is provided with two hooks arranged side by side with the front hook higher than the rear hook. The hooks include a pressing cylinder 508, a mounting base 510, and a zigzag hook body 509 hinged to the mounting base 510. The output end of the pressing cylinder 508 is installed through and has a U-shaped structure 5081 with an opening facing downward. The mounting base 510 has a relief opening 5101 for the hook body 509 to rotate, and the hook body 509 abuts against the opening of the U-shaped structure 5081. When the pressing cylinder 508 presses down, it drives the hook body 509 to rotate upward. When the pressing cylinder 508 retracts, the hook body 509 rotates downward and disengages. This solution places the handle welding at the front end of the bottle body welding. After the handle is welded manually using a handheld welding gun, welding wire is attached, and the cylinder is placed directly into a mesh bag and conveyed via a chain conveyor to the brazing furnace 20 where the welding wire is heated to a high temperature and melted. After cooling, the bottle body is welded and then transported out. After being transported out, two hooks 509 hook the front and back of the mesh bag, which is then lifted by slings and rotated by a rotating frame 503 to one side of the machine platform 10 before being lowered. Once lowered, it is ready for the operator to retrieve, significantly improving overall efficiency. As the mesh bag moves forward, a position switch senses its position, controlling a cylinder to press down and hook the mesh bag when it reaches its designated position.

[0016] Preferably, placement areas 101 are reserved on the left and right sides of the rear of the machine base 10, and the hook is located above the placement area 101 after the rotating frame 503 rotates. Both placement areas 101 can be used to place the net bag, thereby providing the net bag with a certain cooling time.

[0017] Preferably, the brazing furnace 20 includes a furnace box, a burner disposed inside the furnace box, and a gas cylinder 40 disposed outside the furnace box. The gas cylinder 40 supplies gas to the burner to generate high temperature inside the brazing furnace 20 to melt the welding rods preset inside the cylinder and complete the welding. The high-temperature resistant conveyor line 30 passes through the brazing furnace 20.

[0018] As a preferred option, the high-temperature resistant conveyor line 30 is a stainless steel mesh belt conveyor, which is driven by a motor with a drive wheel.

[0019] Preferably, the lifting sling includes a lifting motor 504, a cable seat 505 located at the output end of the lifting motor 504, a cable 507 fixed on the cable seat 505, and two fixed pulleys 506 located on the top of the rotating frame 503.
