Description

Technical Field

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

[0002] In the existing welding technology, the welding of the bell mouth is the old-fashioned riding type. When welding two arc-shaped pipes, the bell mouth of the pipe is made to face downward, and the fixing support is simple and unstable. However, in fact, due to the downward inclination angle of the bell mouth, it is easy to cause the melted flux to not flow into the weld evenly during the welding process, resulting in inflow and weld blockage. The position of the welding material cannot be stably fixed during welding, which will lead to insufficient welds or excessive welds, resulting in welding defects, making the welded part not full and beautiful enough. Utility Model Content

[0003] The main purpose of the utility model is to provide a bell-mouth welding device, so as to at least solve the problem in the prior art that the flux melted downward at the bell-mouth during welding flows unevenly, so that the excess melted flux blocks the weld.

[0004] To achieve the above-mentioned purpose, the bell-mouth welding device of the embodiment of the utility model includes a welding base plate, a fixing block, and a support column; the fixing block is arranged on the welding base plate, the top of the fixing block is a chamfered surface with a preset inclination angle, a receiving groove is opened through the chamfered surface, the length direction of the receiving groove is consistent with the inclination direction of the chamfered surface, and the receiving groove is used to fix one of the arc pipes; the support column is arranged on the welding base plate, the support column is arranged on one side of the fixing block and opposite to the upper edge of the chamfered surface, and the support column is used to support the other arc pipe.

[0005] With this design, the user fixes the two parts of the pipe on the support column and the fixing block respectively during welding so that the bell mouth faces upward, and performs welding around the bell mouth so that the flux can flow into the weld evenly, and the excess melted flux flows out along the inclined pipe or drips directly to prevent the flux from flowing in and clogging the weld. This solves the problem in the prior art that the melted flux with the bell mouth facing downward flows unevenly, causing the excess melted flux to clog the weld.

[0006] Furthermore, an annular base is provided on the upper surface of the welding base plate, and the support column is detachably arranged in the annular base. The support column includes a column body and a support sheet. The column body is detachably arranged in the annular base. With this design, the user can replace the support sheet according to the pipes of different heights. The support sheet is arranged on the top of the column body. The support sheet is an arc surface structure with a preset arc. The support sheet is used to receive another arc-shaped pipe. The support column is used to more stably support the pipe. With the fixed block, the user can adjust the distance between the two pipes during welding to avoid welding defects caused by too large or too small gaps, which leads to the welding place not being full and beautiful.

[0007] Furthermore, the preset curvature of the support piece matches the curvature of the cross section of the pipe, so that the user can place the pipe very conveniently. Also, because the curvature of the support piece matches that of the pipe, the pipe will be more stable and will not shake easily during welding.

[0008] Furthermore, the preset angle of the beveled surface matches the inclination angle of one of the arc-shaped pipes. In this design, the user can tilt the pipe due to the fixing block during welding, which not only allows the flux to flow evenly but also allows excess melted flux that flows into the pipe to flow out along the inclined pipe without clogging the weld.

[0009] The bell-mouth welding device using the embodiment of the utility model includes a welding base plate, a fixing block, and a support column; the fixing block is arranged on the welding base plate, the top of the fixing block is a chamfered surface with a preset inclination angle, a receiving groove is provided on the chamfered surface, the length direction of the receiving groove is consistent with the inclination direction of the chamfered surface, and the receiving groove is used to fix one of the arc pipes; the support column is arranged on the welding base plate, the support column is arranged on one side of the fixing block and is opposite to the upper edge of the chamfered surface, and the support column is used to support the other arc pipe. The two parts of welding materials are fixed on the support column and the fixing block respectively so that the bell mouth faces upward, and the excess melted flux flows out along the inclined pipe. This solves the problem in the prior art that the melted flux with the bell mouth facing downward flows unevenly during welding, causing the excess melted flux to block the weld.

[0010] Beneficial effects of the utility model:

[0011] The support column and the fixing block in the present invention can stably fix and support the pipeline, so that the size of the weld between the bell mouths is fixed during the welding process, welding defects will not occur, and the welding quality is improved.

[0012] In the present invention, the fixing block with an inclined angle and the supporting column with a support piece with a preset curvature respectively support and fix two pipes, so that the welding port of the pipe can be kept at a high position. Starting welding from the top of the bell mouth allows the flux to flow evenly into the weld, preventing the flux from flowing inward during the heating process and causing the flux to accumulate at the weld.
