Description

Technical Field

[0001] The utility model relates to the technical field of butt welding machine auxiliary mechanisms, in particular to a butt welding machine with an autonomous smoke exhaust effect. Background Art

[0002] The working principle of the butt welding machine is to use the resistance heat and a large amount of plastic deformation energy of the welding area itself to make the two separated metal atoms close to the lattice distance, thereby forming a metal bond. After a sufficient amount of common grains are generated on the bonding surface, a weld point, weld or butt joint is obtained.

[0003] The main reason why welding machines need fume exhaust is that a large amount of smoke, harmful gases and particulate matter are generated during the welding process. These smoke and harmful gases mainly come from the high-temperature melting and evaporation of welding materials, as well as the chemical reactions produced during the welding process. These harmful substances can pose a serious threat to the health of welders, such as causing respiratory diseases, eye diseases, etc.

[0004] At present, the automatic smoke exhaust adopted by the welding machine uses a welding smoke exhaust machine for exhaust. This equipment is specially used to collect and purify smoke and exhaust gas during industrial welding operations. It has generally adopted high-efficiency filtration systems and intelligent control technologies. It can effectively capture and filter the fine smoke generated during the welding process, reducing occupational hazards and environmental pollution. In essence, it is to set up a suction hood and an air pump outside the welding machine to extract the smoke. However, this automatic smoke exhaust method currently has the following defects:

[0005] 1. Since the parts to be welded have certain sizes, the fume exhaust machine needs to be moved to meet the needs of different welding parts, which makes the fume exhaust machine inconvenient to use;

[0006] 2. The welding fume exhaust machine is too far away from the welding operation area, making it inconvenient to adjust, and its fume exhaust effect is limited.

[0007] Therefore, we propose a butt welding machine with autonomous fume exhaust effect. Utility Model Content

[0008] The purpose of the utility model is to provide a welding machine with an autonomous smoke exhaust effect to solve the above-mentioned shortcomings in the technology.

[0009] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a butt welding machine with an autonomous smoke exhaust effect, comprising a butt welding machine body and a butt welding mechanism, the butt welding mechanism being installed on the front of the butt welding machine body, the butt welding mechanism comprising an upper butt welding assembly and a lower butt welding assembly, a bracket being installed above the upper butt welding assembly, a cylinder being vertically installed on the bracket to drive the upper butt welding assembly at the output end to rise and fall and then approach the lower butt welding assembly for butt welding operations, a threaded rod being provided at the output end of the cylinder, and the other end of the threaded rod being installed on the upper butt welding assembly, an outer thread of the threaded rod being connected to an angle adjustment rotating frame, a height adjustment assembly being installed on one side of the angle adjustment rotating frame, an air suction hood being installed at the bottom telescopic end of the height adjustment assembly, and the position of the air suction hood being adjusted by rotating the angle adjustment rotating frame.

[0010] Furthermore, the angle adjustment rotating frame rotates around the threaded rod through the internal threaded hole and can be adjusted from one side to the other side through the upper butt welding component.

[0011] Furthermore, a connecting rod is provided between the angle adjustment rotating frame and the height adjustment assembly.

[0012] Furthermore, the height adjustment assembly includes a sleeve, a sliding rod, a fixed knob and a locking groove. The outer periphery of the sleeve is fixed to the connecting rod near the bottom, and a fixed knob that can be screwed into the sleeve is installed on the outer side of the corresponding connecting rod. The sliding rod is slidably connected inside the sleeve and extends out of the bottom, and a locking groove is provided on the outer wall of the sliding rod vertically corresponding to the fixed knob screw. By rotating the fixed knob forward and backward, it can contact / move away from the locking groove, so that the sliding height of the sliding rod is locked.

[0013] Furthermore, the suction hood is connected to an exhaust fan installed on the back of the welding machine body through an air duct, and the exhaust fan is connected to a smoke exhaust treatment system.

[0014] Furthermore, the suction hood is a semicircular structure, and the end corresponding to the welding mechanism is an open design.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. By integrating the suction hood on the welding machine and using the combination of threaded rods, angle adjustment rotating frame and height adjustment components, the suction hood can be adjusted in all directions, including horizontal and vertical movement and angle rotation. The position of the suction hood can be easily adjusted to adapt to welded parts of different sizes and positions, greatly improving the convenience and flexibility of fume exhaust.

[0017] 2. Since the suction hood is directly set near the welding area and is close to the welding operation, it can more effectively capture the smoke and harmful gases generated during the welding process, significantly improve the smoke exhaust effect, and reduce occupational hazards and environmental pollution.

[0034] Among them, the suction hood 6 can be disassembled and replaced with different models to improve applicability and suction requirements. Example 2

[0035] like Figure 1-3 As shown, the angle adjustment rotating frame 4 rotates around the threaded rod 3 through the internal threaded hole and can be adjusted from one side to the other side through the upper butt welding component 21.

[0036] A connecting rod 41 is provided between the angle adjustment rotating frame 4 and the height adjustment assembly 5 , and the connecting rod 41 connects the angle adjustment rotating frame 4 and the sleeve 51 .

[0037] The height adjustment assembly 5 includes a sleeve 51, a sliding rod 52, a fixed knob 53 and a locking groove 54. The outer periphery of the sleeve 51 is fixed to the connecting rod 41 near the bottom, and a fixed knob 53 that can be screwed into the sleeve 51 is installed on the outer side of the corresponding connecting rod 41.
