Description

Technical Field

[0001] The utility model relates to the technical field of welding operation auxiliary equipment, in particular to a welding workbench device. Background Art

[0002] Welding is one of the routine operations in mechanical processing. Welding can place the workpiece to be welded on the workbench for easy operation. For example, when using welding rods to weld metal workpieces, a large amount of welding slag will be generated during the welding process, and some welding smoke will also be generated. Cleaning is required from time to time during the operation. At the same time, in order to prevent the welding smoke from affecting the surrounding environment, a welding smoke purification device is also required. Generally, an exhaust fan is used to extract the welding smoke. During the specific operation, the welding slag will fall directly onto the workbench and needs to be cleaned with a brush or other tools. The welding slag is scattered and cleaning may take a long time. The placed exhaust fan also needs to align the air inlet pipe with the position where the welding smoke is generated. Therefore, it needs to be constantly adjusted with the change of the processing position, resulting in a decrease in overall efficiency. Utility Model Content

[0024] In an exemplary embodiment, Figure 1 , 2 As shown, the present embodiment provides a welding workbench device, which includes a horizontally arranged installation frame 1, and the four corners of the installation frame 1 are respectively fixedly connected with support legs 2, and a slag receiving bucket 3 located below the installation frame 1 is also fixedly connected between the four support legs 2, and an opening and closing pipe 4 is also arranged at the lower end of the slag receiving bucket 3, and a plug plate 5 that can be pulled out horizontally is arranged on the opening and closing pipe 4 and can be opened and closed; a plurality of pairs of support grooves 6 are respectively recessed on the opposite side walls on the top surface of the installation frame 1, and a support bar 7 is respectively clamped between each pair of support grooves 6, and the upper end surfaces of all support bars 7 are located in a plane and higher than the installation frame 1, and the upper end surfaces of all support bars 7 are arranged flush; a mounting pipe 8 is also fixedly connected in the installation frame 1, the mounting pipe 8 is horizontally arranged and one end extends to the outside of the installation frame 1 and is connected to an exhaust fan 9, and a plurality of air intake pipes 10 are also installed on the mounting pipe 8.

[0025] In the above embodiment, the workpiece is placed on the support bar 7 for welding. During the process, the lower plug plate 5 is inserted into the opening and closing tube 4, and the opening and closing tube 4 is in a closed state. The generated welding slag will fall downward into the slag receiving bucket 3, so that it is convenient to be uniformly discharged through the opening and closing tube 4. The installation pipe 8 is set to generate negative pressure in the installation frame 1 through the air inlet pipe 10 through the operation of the exhaust fan 9, so that the generated welding smoke is extracted downward without position adjustment, which solves the problem of reduced overall efficiency caused by welding slag cleaning and air inlet adjustment of the exhaust fan 9 in the prior art; specifically, the support bar 7 in this scheme is square and the top surface is flat, which can be adjusted according to the specific The number of support bars 7 to be installed is selected according to the actual situation. The two ends of each support bar 7 are respectively connected with a pair of support grooves 6 to facilitate disassembly and installation. More specifically, the support groove 6 is arranged on one side close to the installation frame 1. The support groove 6 is a structure with a larger upper part and a smaller lower part. The support bar 7 is connected with the lower end of the support groove 6. The upper end is larger, which is convenient for the support bar 7 to be inserted downward, and the lower end is smaller, which makes the connection possible. At the same time, this also makes it easier to disassemble. There is a distance between the support bars 7, so that the welding smoke and welding slag can move downward smoothly; the air outlet pipe of the exhaust fan 9 can be connected to a separately arranged purification equipment to purify the welding smoke before discharging it to the outside.

[0026] In a further exemplary embodiment, Figure 1 , 3 As shown, one end of the air inlet pipe 10 is connected to the mounting pipe 8, and the other end is provided with an opening facing downward, and the connection between the air inlet pipe 10 and the mounting pipe 8 is located below the mounting pipe 8, so that the welding slag will not enter the opening to cause blockage during the downward falling process, and at the same time, it will not affect the extraction of welding smoke; in more detail, the installation pipes 8 can be multiple, and then connected and connected by the horizontal pipe 11 outside the installation frame 1, and then connected to the exhaust fan 9, so that the effect of extracting welding smoke can be better;

[0027] In more detail, the end of the mounting tube 8 located outside the mounting frame 1 is threadedly connected to a rotating sleeve 12, and the end of the rotating sleeve 12 away from the mounting tube 8 is also rotatably connected to a hose 13, and the end of the hose 13 away from the rotating sleeve 12 is connected to the air inlet pipe of the exhaust fan 9. In the case of multiple mounting tubes 8, a connecting tube 14 can be fixedly connected to the horizontal tube 11, and then the rotating sleeve 12 can be threadedly connected to the connecting tube 14, so that when the hose 13 is connected, the rotating sleeve 12 can rotate smoothly without affecting the setting of the hose 13, which is more convenient. Specifically, a sliding ring groove is recessed on the inner wall of the rotating sleeve 12, and a sliding ring 15 which can slide relatively in the sliding ring groove is provided on the fixed sleeve outside the hose 13. When the rotating sleeve 12 is rotated, the rotating sleeve 12 rotates relative to the sliding ring 15, thereby not affecting the hose 13. At the same time, when the exhaust fan 9 is running, the sliding ring 15 and the sliding ring groove can also play a certain sealing role to prevent the welding smoke from leaking outward at the connection. A sealing gasket can be added between the rotating sleeve 12 and the connecting pipe 14 (or the mounting pipe 8) to prevent the welding smoke from leaking outward.

[0028] like Figure 1 As shown, in a further exemplary embodiment, a plurality of longitudinal bars 16 parallel to the support bar 7 and a plurality of transverse bars 17 perpendicularly intersecting the longitudinal bars 16 are fixedly connected in the mounting frame 1, and the longitudinal bars 16 and the transverse bars 17 are both located between the mounting tube 8 and the support bar 7, and the transverse bars 17 and the longitudinal bars 16 together form a plurality of protective partition frames, similar to a protective net, which can prevent the workpiece from falling. When the workpiece falls, the support bar 7 can be removed, and then the workpiece can be taken out.

[0029] like Figure 1 As shown, in a further exemplary scheme, the upper outer wall of the slag receiving bucket 3 is fixedly connected with a connecting frame 18, and the four corners of the connecting frame 18 are respectively fixedly connected to the four supporting legs 2, so that the slag receiving bucket 3 and the supporting legs 2 are fixedly connected through the connecting frame 18. At the same time, the lower end of the mounting frame 1 is connected to the upper end of the slag receiving bucket 3. When the exhaust fan 9 is running, the opening and closing pipe 4 below is in a closed state, so that the welding smoke above is smoothly drawn downward.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
