Description

Technical Field

[0001] The utility model relates to the technical field of plate cutting and welding, and in particular to a cost reduction device for continuously splicing and cutting plates. Background Art

[0002] Metal composite plate refers to a plate with another metal on top of a layer of metal, so as to save resources and reduce costs without reducing the use effect (anti-corrosion performance, mechanical strength, etc.). The composite methods usually include explosive composite, explosive rolling composite, rolling composite, etc. Composite materials can be divided into composite plates, composite pipes, composite rods, etc. according to their appearance. They are mainly used in anti-corrosion, pressure vessel manufacturing, power construction, petrochemical, medicine, light industry, automobile and other industries.

[0003] At present, the metal composite panels produced by the original manufacturers are standard panels as a whole, and their length and width are subject to certain restrictions. When products need to be produced later, the metal composite panels will be cut according to the size of the products. Before cutting, the entire metal composite panel is placed on a conveying device, and then the two sides of the metal composite panel are limited by a limiting device. After limiting, it is then conveyed to the cutting device, and then it is cut to obtain the metal composite panel required for the product.

[0004] Since the size of the product cannot be fixed during the production of the above-mentioned product, it is impossible to ensure that the metal composite plate is cut into equal parts when the metal composite plate is cut, so that waste is easily generated after the metal composite plate is cut, thereby causing a waste of resources.

[0047] The working principle and use process of this utility model:

[0048] In use:

[0049] During operation, first, place the first plate on the conveying roller 33. At this time, rotate the limiting threaded rod 42. As the limiting threaded rod 42 rotates, the limiting plate 43 is driven to move. As the limiting plate 43 moves, the two ends of the first plate can be limited. After limiting, adjust the second limiting assembly 7. After adjustment, the distance between the stop plate 103 and the plasma cutting machine 96 can be adjusted according to the cutting length. When adjusting, first, rotate the stop threaded rod 102. As the stop threaded rod 102 rotates, the stop plate 103 is driven to move, thereby adjusting the position of the stop plate 103. After adjustment, start the drive motor 3. 4, the driving motor 34 drives the rotating shaft 35 to rotate. When the rotating shaft 35 rotates, it drives the conveying roller 33 to rotate. When the conveying roller 33 rotates, the plate starts to be conveyed. When the other end of the first plate moves to the bottom of the welding assembly 5, it will also be located above the auxiliary conveying assembly 6. At this time, the first plate will not be able to move forward. At this time, the second plate is placed above the conveying assembly 3, and then one end of the second plate is conveyed to the bottom of the welding assembly 5 through the conveying assembly 3, and one end contacts one end of the first plate. At this time, the lifting hydraulic rod 52 drives the first pressing plate 54, the second pressing plate 55 and the plasma welding gun 511 downward. Move, when the first pressure column 56 and the second pressure column 57 clamp and fix the two plates respectively, at this time, start the welding motor 512, the welding motor 512 drives the welding threaded rod 510 to rotate, when the welding threaded rod 510 rotates, it will drive the plasma welding gun 511 to move, so that the gap between the two plates can be welded, and the plates can be welded into one plate. After welding, at this time, start the conveying component 3, the conveying component 3 drives the welded plate to move forward, when one end of the plate contacts the stop plate 103, the first plate can no longer be conveyed forward, at this time, start the cutting motor 95, and the cutting motor 95 works When the cutting thread rod 94 is rotated, it will drive the cutting thread rod 94 to rotate. When the cutting thread rod 94 is rotated, it will drive the plasma cutter 96 to move. When the plasma cutter 96 moves, it can realize the cutting of plates of different widths. After cutting, at this time, the hydraulic rod 81 will drive the receiving plate 82 to move downward, thereby driving the cut plate to move forward. At this time, the uncut plate will continue to be conveyed forward under the action of the conveying roller 33, so that the plate to be cut is located above the cut plate. At this time, the cutting motor 95 will be able to drive the plasma cutter 96 to move again for cutting again, thereby avoiding waste.
