Description

Technical Field

[0001] The invention relates to the field of full-automatic welding, and in particular to a full-automatic welding device for manufacturing chemical pressure vessels. Background Art

[0002] During the welding process of pressure vessels, the axis of the welding gun nozzle must be coplanar with the axis of the pressure vessel, and the nozzle must be in the center of the weld to ensure the welding quality. However, due to the different diameters of different pressure vessels, the position of the welding gun must be adjusted to ensure that the welding gun is in the center of the weld. Therefore, the existing welding equipment cannot meet the welding operations of pressure vessels of various sizes, resulting in high limitations in use.

[0003] In the existing technology, such as the utility model patent with authorization announcement number CN220659701U: welding equipment for pressure vessel manufacturing, which includes a main support, a self-propelled mechanism and a welding mechanism, the self-propelled mechanism is installed on the main support, and the welding mechanism is fixedly installed on the self-propelled mechanism; the welding mechanism includes a welding support, a support plate, an adjustment guide rail, a lifting slide, a lifting slider, a transmission box, a slide, an adjustment motor, a linkage plate, a lifting cylinder and a welding gun, the welding support is fixedly installed on the self-propelled mechanism, the support plate is fixedly installed on the welding support, two groups of adjustment guide rails are symmetrically fixedly installed at the bottom of the support plate, four groups of lifting sliders are fixedly installed on the top of the lifting slide, and the four groups of lifting sliders are respectively slidably mounted on the two groups of adjustment guide rails, the transmission box is fixedly installed on the top of the support plate, the slide is slidably mounted on the transmission box, and a screw is rotatably arranged inside the transmission box.

[0004] When welding pressure vessels in the existing technology, since the interior of the container is mostly in a closed state, it is difficult for the welding parts located outside the container to weld the inner wall of the container, resulting in low welding strength when welding a single surface of the container, which makes it easy for the container weld to rupture and leak when the internal pressure of the container is high. At the same time, since a large amount of harmful gases, such as carbon monoxide and nitrogen oxides, are easily generated during container welding, the air around the welding equipment is seriously polluted when a large amount of harmful gases are dispersed, resulting in low cleanliness of the welding equipment when it is working.

[0005] Therefore, it is necessary to provide a fully automatic welding device for manufacturing chemical pressure vessels to solve the above technical problems. Summary of the invention

[0006] The present invention provides a fully automatic welding device for manufacturing chemical pressure vessels, which solves the problems that since most of the inside of the vessel is in a closed state, it is difficult for the welding components located outside the vessel to weld the inner wall of the vessel, resulting in relatively low welding strength during single-surface welding of the vessel, and when the internal pressure of the vessel is relatively large, it is easy to cause the weld of the vessel to rupture and leak air.

The bottom of the support column 221 is equipped with a sliding wheel 222. By setting the moving mechanism 22, when the welding device needs to be moved and transported, the support table 1 is pushed, so that the sliding wheel 222 drives the support table 1 to move horizontally through the support column 221, that is, drives the sliding table 4 to move horizontally, thus achieving the effect of moving and transporting the welding device, and bringing convenience to the adjustment of the working position of the welding device.

[0029] The working principle of a fully automatic welding device for manufacturing chemical pressure vessels provided by the present invention is as follows: First, when welding a pressure vessel, fix the vessel on the top of the sliding table 4 and horizontally move the sliding table 4 so that the sliding table 4 drives the vessel to sleeve outside the first welding torch 93. At this time, start the first motor 94 so that the first motor 94 drives the first electric telescopic rod 91 to flip through the driving gear 95, thus achieving the adjustment effect of the angle of the first welding torch 93. At this time, start the first electric telescopic rod 91 so that the first electric telescopic rod 91 drives the welding end of the first welding torch 93 to abut against the inner wall surface of the vessel, so that the first welding torch 93 can weld the inner wall of the vessel, and then achieve the double welding effect of the inside and outside of the vessel, thus greatly improving the welding strength of the pressure vessel. When horizontally welding the vessel, fix the pressure vessel on the top of the sliding table 4. At this time, start the second motor 11 so that the second motor 11 drives the sliding block 10 to move horizontally through the threaded rod 12, that is, drives the sliding table 4 to move horizontally, so that the sliding table 4 drives the pressure vessel to move horizontally, thus bringing convenience to the horizontal welding of the pressure vessel. When welding the pressure vessel is required, place the pressure vessel on the top of the sliding table 4. At this time, start the second air cylinder 14 so that the second air cylinder 14 drives the extrusion seat 23 to tightly press on the top of the pressure vessel, thus achieving the extrusion clamping and fixing effect of the pressure vessel. When circular welding of a circular vessel is required, place the vessel on the top of the sliding table 4. At this time, start the third air cylinder 151 so that the third air cylinder 151 drives the third motor 153 to move up and down through the limit seat 152, that is, drives the driving roller 154 to tightly press on the top of the circular vessel. At this time, start the third motor 153 so that the third motor 153 drives the circular vessel to rotate on the top of the sliding table 4 through the driving roller 154, so that the first welding torch 93 can perform circular welding on the rotating vessel, thus bringing convenience to the circular welding of the vessel, and improving the functionality of the welding device. When driving the circular vessel to rotate, a plurality of sliding balls 16 support the circular vessel, avoiding the problem of friction between the vessel and the top of the sliding table 4 during rotation, thus improving the smoothness of the vessel during rotation. When welding height adjustment is required, start the fourth air cylinder 18 so that the fourth air cylinder 18 drives the auxiliary mechanism 20 to move up and down through the second lifting block 19, that is, drives the second welding torch 202 to move up and down, thus achieving the adjustment effect of the welding height. When welding the pressure vessel, fix the vessel on the top of the sliding table 4. At this time, start the second electric telescopic rod 201 so that the second electric telescopic rod 201 drives the second welding torch 202 to reciprocate, prompting the welding end of the second welding torch 202 to press against the side of the vessel, so that the second welding torch 202 can weld the surface of the vessel, and then achieve the automatic welding effect of the surface of the pressure vessel. When welding the pressure vessel, start the industrial vacuum cleaner 211 so that the industrial vacuum cleaner 211 sucks the air around the welding end of the first welding torch 93 through the hose 212, that is, sucks the smoke and dust generated during welding.This avoids the problem of air pollution caused by a large amount of welding fumes floating around, thereby improving the cleanliness of the welding device during operation. When the welding device needs to be moved and transported, the support table 1 is pushed, so that the sliding wheel 222 drives the support table 1 to move horizontally through the support column 221, that is, drives the sliding table 4 to move horizontally, thus achieving the effect of moving and transporting the welding device, and further bringing convenience to the adjustment of the working position of the welding device.
