Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to mesh plate bending and rolling welding equipment used for manufacturing a diverter of a pressure swing adsorption nitrogen generator. Background Art

[0002] The pressure swing adsorption nitrogen generator is a device that uses pressure swing adsorption technology to produce high-purity nitrogen. It has been widely used in various industrial fields.

[0003] In principle, the pressure swing adsorption nitrogen generator uses the pressure swing adsorption method to produce nitrogen. Specifically, it uses air as the raw material and uses a high-efficiency, high-selectivity solid adsorbent to selectively adsorb nitrogen and oxygen to separate nitrogen and oxygen from the air. Solid adsorbents mostly use carbon molecular sieves. The separation effect of carbon molecular sieves on nitrogen and oxygen is mainly based on the different diffusion rates of the two gases on the surface of the carbon molecular sieve. The smaller diameter gas (oxygen) diffuses faster and enters the molecular sieve solid phase more, so that nitrogen enrichment components can be obtained in the gas phase. After a period of time, the molecular sieve's adsorption of oxygen reaches equilibrium. According to the characteristics of the carbon molecular sieve's different adsorption amounts of adsorbed gas under different pressures, the pressure is reduced to release the carbon molecular sieve from the adsorption of oxygen. This process is called regeneration. The pressure swing adsorption method usually uses two towers in parallel, alternating between pressurized adsorption and decompression regeneration to obtain a continuous nitrogen flow.

[0004] The structure of the pressure swing adsorption nitrogen generator mainly includes an air power system, an air purification system, an air separation system, and a storage control system. Specifically, it includes main components such as an air compressor, an air buffer tank, a dryer, left and right adsorption towers, and an oxygen buffer tank. In terms of the process, the raw air is compressed by the air compressor and enters the air buffer tank. It is then dusted, degreased, and dried by the dryer, and finally enters the left and right adsorption towers through the air intake valve for adsorption and nitrogen production. The air buffer tank is a tank body used to store buffered compressed air. A diverter is fixed at the lower end of the air buffer tank. The diverter is a component used to grade and turbulent the compressed air. Structurally, it is a circular cylinder with an open upper end, which is welded by a circular bottom plate and an annular mesh plate.

[0005] As mentioned above, the particularity of the shape and composition of the PSA nitrogen generator splitter requires multiple processes including cutting, bending and welding during processing. Cutting is mainly to define the shape of the circular bottom plate, bending is to curl the strip mesh into a ring mesh, and welding is to weld the circular bottom plate and the ring mesh together. It is not difficult to see that the processing of the nitrogen generator splitter involves multiple complex processes, so that in the process of manufacturing and processing it with existing equipment, there are often the following problems:

[0006] 1. The equipment has a single function and can only process a single process of the diverter. As a result, during the entire processing process, the various components that make up the diverter need to be frequently transferred and switched between multiple different devices, resulting in a decrease in processing efficiency.

[0007] 2. The various components of the diverter are difficult to clamp, position, transfer and transport.

[0008] 3. The strip mesh has low bending and rolling precision and it is inconvenient to take out the annular mesh after forming.

[0009] 4. The welding method is single, and it is difficult to meet the diversified welding needs. Specifically, in the welding process of the nitrogen generator manifold, it includes the welding of the annular mesh plate itself and the welding of the annular mesh plate and the circular bottom plate. Among them, the welding of the annular mesh plate itself is straight seam welding, while the connection between the annular mesh plate and the circular bottom plate requires circular welding. Obviously, a single welding method cannot adapt to the above-mentioned diversified welding types.

[0010] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] The present invention can not only realize various welding processes of annular mesh plates and circular bottom plates, but also realize the bending and rolling of strip mesh plates during the conveying process, and the whole process is carried out continuously, thereby greatly improving the manufacturing and processing efficiency of the nitrogen generator diverter.

[0034] The transfer conveying assembly provided in the present invention can realize the segmented transfer of the strip mesh during the diverter forming process. Specifically, during the process, the strip mesh to be welded is first placed flat on two conveyor belts for horizontal conveying, and then the transmission drive motor is started to drive the sliding base to slide horizontally along the sliding limit opening, and when the sliding base moves to the bottom of the strip mesh, the lifting and telescopic cylinder is controlled to extend to drive the transfer pallet to rise, and the strip mesh is lifted up, so that it is separated from the conveyor belt and transferred to the transfer pallet. The sliding base continues to move horizontally to transfer the strip mesh to the bottom of the bending and rolling forming assembly, ready for subsequent forming processing.

[0035] The bending and rolling forming assembly provided in the present invention can automatically bend the strip mesh plate into an annular mesh plate. Specifically, during the bending and rolling forming process, the strip mesh plate is transferred from the transfer pallet to the two forming frames by controlling the shortening of the lifting and telescopic cylinders, and then the rotary drive motor is started to drive the roll forming cylinder to rotate, control the extension of the hydraulic telescopic cylinder, drive the motor mounting plate to descend, and at the same time control the extension of the two displacement telescopic cylinders located below the forming frame respectively, so that the two forming dies located below are aligned with the joining dies, and the strip mesh plate is pressed into the forming dies by using the rotating and pressing rolling forming cylinder. After the rolling forming is completed, the strip mesh plate becomes a U-shaped mesh plate with an open upper end, and then the two displacement telescopic cylinders located above the forming frame are respectively controlled to extend, and the upper part is used to press the strip mesh plate into the forming dies. The two forming dies extrude the U-shaped mesh plate from both sides, so that the strip mesh plate is completely fitted into the roll-forming cylinder, thereby obtaining an annular mesh plate. Since in the above-mentioned forming method, the strip mesh plate is bent and rolled tightly against the roll-forming cylinder, the bending and rolling accuracy can be greatly improved; further, after the bending and rolling is completed, the roll-forming cylinder is controlled to rise so that its outer peripheral wall is abutted against the lower end of the push vertical plate, and the annular mesh plate can be pushed out laterally by controlling the extension of the push telescopic cylinder to facilitate the removal of the parts; in addition, the intermediate clamping seat and the arc-shaped inner support plate telescopically arranged in the roll-forming cylinder can support and clamp the inner side of the annular mesh cylinder during the welding process.

[0036] The multifunctional welding assembly provided in the present invention can realize the combined processing of straight seam welding and circular welding at the same time. Specifically, during the welding process, the circular bottom plate is first adsorbed and clamped on the circular magnetic seat, and the rotation drive motor is started to control the rotation of the roll forming cylinder so that the annular mesh plate is turned to face the joint upward, and the swing vertical plate is driven to swing up to a vertical state, and the extension and telescopic cylinder is controlled to be extended and extended, and the automatic welding gun is used to first perform straight seam welding on the joint of the annular mesh plate, and then the positioning telescopic cylinder is controlled to extend so that the circular bottom plate is connected to one side port of the annular mesh plate, and the rotation drive motor and the stepper motor are started at the same time to drive the annular mesh plate and the circular bottom plate to rotate synchronously respectively, and the automatic welding gun is used to perform circular welding on the joint of the annular mesh plate and the circular bottom plate.
