Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of butt fusion welding machines and relates to a butt fusion welding machine box with a convenient mobile structure. Background Art
[0002] The shortcomings of existing butt fusion welding machines in providing stable clamping of pipes for welding are primarily due to uneven clamping force and complex clamping mechanisms. These shortcomings arise from limitations in mechanical design, inconsistent material properties, and the impact of temperature fluctuations on the pipe during welding. For example, uneven clamping force often occurs when the clamp design fails to adequately account for the varying shapes and sizes of the pipes, resulting in an inability to maintain absolute stability during welding, which in turn affects weld quality. Complex clamping mechanisms arise from the need to accommodate pipes of varying diameters and wall thicknesses. This complicates the mechanical structure, increases operational difficulty and maintenance costs, and reduces production efficiency. Conventional solutions include using adjustable clamps and increasing the number of clamping points. However, these approaches also have drawbacks. While adjustable clamps can accommodate pipes of varying sizes, they increase operational complexity and time costs. While increasing the number of clamping points improves stability, it also increases equipment cost and the difficulty of clamping. Therefore, there is an urgent need for a butt fusion welding machine chassis with a convenient and mobile structure to address these issues. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a hot melt butt welding chassis with a convenient mobile structure to solve the problems raised in the above background technology.
[0004] The utility model is realized by the following technical solutions: a hot melt butt welding machine box with a convenient mobile structure, comprising: a top shell and a welding cavity, a top shell second is provided on the right side of the top shell for covering the upper end of the right side of the welding cavity, and the lower ends of the top shell first and the top shell second are provided with welding cavities for hot melt butt welding of pipe fittings;
[0005] The welding cavity includes an inner frame and an inner embedded hole. The inner frame is a rectangular structure and is made of aluminum alloy steel. A group of lower brackets for supporting the lower end of the pipe to be welded is provided in the middle position on the left side of the inner frame.

By using the lower clamping frames and the upper clamping frames, the pipe fittings to be welded can be supported on the upper and lower sides, thereby providing stable support during the hot melt welding process of the pipe fittings to be welded.
[0007] As a preferred embodiment, the upper end of the upper clamping frame is connected and fixed to the inner side of the lower end of the top shell and the inner side of the lower end of the top shell.

The top shell one and the top shell two have the same specifications, and the top shell one and the top shell two are movably connected to the base through a hinge shaft. By using the fan and the exhaust duct, the welding smoke from the hot melt welding inside the welding chamber can be extracted and centrally processed, thereby preventing the welding smoke from drifting and causing physical harm to the workers.
[0011] As a preferred embodiment, a group of hot melt grooves for hot melt butt welding is provided between the top shell one and the top shell two, a group of ring hot melt machines are provided on the rear side of the hot melt grooves, and a group of bases are provided at the lower ends of the top shell one and the top shell two. The cross-section of the base is a rectangular structure when viewed from above, and a group of moving wheels are provided at the lower ends of the four groups of positive corners of the base to facilitate the movement of the whole.
[0012] As a preferred embodiment, the upper left end of the base and the lower left end of the top shell 1, as well as the upper right end of the base and the lower right end of the top shell 2, are respectively provided with a group of grooves for inserting the pipe body to be welded, and the left side of the base is provided with two groups of smoke guide pipes for extracting the welding smoke inside the welding cavity.

[0024] See also Figures 1-4 A butt fusion welding chassis with a convenient mobile structure includes: a top shell 100, a smoke guide tube 160, and a welding chamber 180.

[0025] The welding chamber 180 includes an inner frame 18a, an upper bracket 18b, an exhaust pipe 18f, an anti-slip inner layer 18g, and an inner hole 18h. The inner frame 18a is a rectangular structure and is welded from aluminum alloy steel. A set of lower brackets 18c for supporting the lower ends of the pipes to be welded is provided in the middle of the left side of the inner frame 18a.

[0027] The upper end of the upper clamping frame 18b is connected and fixed to the inner side of the lower end of the top shell 100 and the inner side of the lower end of the top shell 2 120.

When the upper clamping frame 18b and the lower clamping frame 18c form a circular structure, the two sets of anti-slip inner layers 18g are both in contact with the upper and lower sides of the pipe to be welded. By using the anti-slip inner layer 18g, the clamping friction of the pipe to be welded can be improved, thereby supporting the pipe to be welded while preventing it from moving and affecting the hot melt welding effect.
[0029] A set of fans 18e for extracting welding smoke from the hot melt tank 130 is provided at the lower end of the middle position of the welding chamber 180, and a set of internal dust-blocking nets 18d for blocking hot melt debris and dust are provided at the upper end of the fans 18e.

The fan 18e and the exhaust duct 18f can be used to extract and concentrate the welding smoke from the hot melt welding inside the welding chamber 180, thereby preventing the welding smoke from dispersing and causing physical harm to the workers.

A group of partitions 12d are provided between the flame-retardant layer 12b and the thermal insulation layer 12c to improve the thermal insulation effect.
[0034] See also Figures 1-4As the first embodiment of the present invention: First, the staff will insert the two sets of pipe fittings to be heat-melted into the corresponding two sets of embedding grooves 150 respectively, and pass through the two sets of embedded holes 18h on the left and the two sets of embedded holes 18h on the right. Then, the two sets of pipe fittings to be heat-melted are kept at the center position inside the heat melting groove 130. At the same time, since the inner side of the lower end of the upper clamping frame 18b and the inner side of the upper end of the lower clamping frame 18c are both provided with a non-slip inner layer 18g for improving the clamping friction of the pipe fittings to be welded, when the upper clamping frame 18b and the lower clamping frame 18c are connected, the pipe fittings are welded together.

The anti-slip inner layer 18g can be used to improve the clamping friction of the pipe to be welded, thereby supporting the pipe to be welded while preventing it from moving and affecting the hot melt welding effect. Subsequently, a set of hot melt grooves 130 for hot melt butt welding is provided between the top shell 100 and the top shell 2 120, and a set of ring hot melt machines are provided on the rear side of the hot melt grooves 130. The staff uses the ring hot melt machines to perform hot melt butt welding operations between the two sets of pipes.
[0035] See also Figures 1-4 , as the second embodiment of the present invention: based on the explanation in the above embodiment, further, when the two groups of pipes to be welded are being welded, the welding smoke generated during the welding process floats in the middle position inside the welding chamber 180. Since a group of fans 18e for extracting the welding smoke inside the hot melt tank 130 is provided at the lower end of the middle position of the welding chamber 180, a group of internal dust-blocking nets 18d for blocking hot melt debris and dust are provided at the upper end of the fan 18e, and two groups of exhaust pipes 18f for draining the welding smoke are provided on the left side of the fan 18e. Each group of exhaust pipes 18f is sealed and connected to a group of smoke guide pipes 160. Then the staff starts the fan 18e and the exhaust pipe 18f to extract the welding smoke from the hot melt welding inside the welding chamber 180 and transmit it to the outside of the exhaust pipe 18f for centralized treatment, thereby preventing the welding smoke from floating and causing physical harm to the staff.
