Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to an automatic steel strip butt welding machine with a guide port. Background Technology

[0002] Butt welding machines, also known as current welding machines or resistance welding machines, utilize the resistance between the contact surfaces of two workpieces. A low voltage and high current are instantaneously passed through the contact surfaces, causing the two mating metals to heat up instantly, melt, and fuse. Flash butt welding has a wide range of applications; in principle, any forgeable metal material can be welded using flash butt welding. For example, low-carbon steel, high-carbon steel, alloy steel, stainless steel, and other non-ferrous metals and alloys can all be welded using flash butt welding.

[0003] A search revealed application number CN202223565692.3, entitled "Automatic Welding Device for Steel Strip Butt Welding Machine," belonging to the field of steel strip butt welding technology. This automatic welding device includes a support assembly and a welding assembly. The support assembly includes a support section and a conveying section, with the conveying section mounted on the support section. The welding assembly includes a transmission section, a shearing section, and a welding section. The transmission section is mounted on the conveying section, the shearing section on the transmission section, and the welding section on the shearing section. The support section also includes a collection box and a discharge gate. The collection box is fixed to the lower surface of the base, and its inner bottom wall is inclined. The collection box and the discharge trough are correspondingly arranged, and the discharge gate is hinged to the collection box.

[0004] However, this solution only has one shearing blade, and the shearing process requires moving along the steel belt, which is time-consuming, labor-intensive, and inefficient. In addition, the welding machine is controlled by two bolts. Although the two bolts are connected by a conveyor belt, they are not synchronized, which poses a great risk. Asynchrony will lead to uneven weld strips and thus reduce the welding strength. Welding pressure rollers are used to press the steel belt during welding, but the pressing area is too small, which will reduce the welding strength. Moreover, the active roller is used to drive the steel belt, but there is no limiting device, which makes it impossible to determine whether the alignment is correct, increasing the workload of workers and reducing efficiency.

[0005] Therefore, it is necessary to propose an automatic steel strip welding machine with a guide port to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an automatic steel strip welding machine with a guide port to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automatic steel strip welding machine with a guide port includes a frame, a feeding device, a clamping device, a cutter, a welding device, a first limiting block, a second limiting block, a collection frame, a feeding table, and a welding table.

[0034] In the specific implementation process, it should be noted that the first limiting block 6 includes a push screw 603, a fixing hole 605, a mounting plate 604, a threaded groove 607, and a baffle 606. The mounting plate 604 is installed on the feeding table 15 to fix the first limiting block 6. The push screw 603 and the baffle 606 are rotatably connected through the fixing hole 605. The push screw 603 is connected to the mounting plate 604 through the threaded groove 607. The threaded groove 607 is used for the push screw 603 to push the baffle 606 to a designated position.

[0035] In the specific implementation process, it should be noted that a number of support columns 102 are provided below the frame 1, and a number of support legs 9 are provided below the feeding platform 15.

[0036] The working principle of this embodiment is as follows: In specific use, the operator first adjusts the position of the first limiting block 6 and the second limiting block 7 using the push screw 603 and the limiting ruler, and then places the steel strip to be welded on the feeding table 15. Then, the first guide roller 502 and the second guide roller 503 driven by the motor ensure the flatness of the steel strip and drive the steel strip forward to the position. After reaching the position, the lifting rod 3 drives the pressing block 4 to press to ensure that the position does not change and that the steel strip is evenly stressed after pressing to ensure that there is no deformation after cutting. Then, the hydraulic device 10 is started to drive the cutter 11 to move downward. The shearing blades 113 on both sides of the cutter 11 are made of sturdy and durable materials. The metal used ensures the flatness and neatness of the cut steel strip after cutting. Then, the two steel strips are cut to ensure a smooth and neat welding surface. Then, the sliding machine 103 moves in the sliding groove A101 to move the pressing block 4 and the two pressed steel strips to the welding table 14 for welding. First, the movable welding machine 104 and the sliding groove B202 are used to bring the welding rod 2 and the welding head 201 to one end of the steel strip to be welded. Then, the telescopic arm 203 moves the welding rod 2 and the welding head 201 to the steel strip for welding. If welding is continuous, the telescopic arm 203 only needs to move the welding rod 2 and the welding head 201 to the top without affecting the cutter 11.

[0037] In practical use, the sliding mechanism 103, lifting rod 3, hydraulic device 10, telescopic arm 203, and movable welding machine 104 used in this utility model can be manually controlled by buttons, or they can be automated using a pre-defined operating program from a Siemens PLC such as S7-200 Smart or S7-1200 series. Those skilled in the art can choose the appropriate control method according to actual needs. Control is a conventional technical means and will not be elaborated further here.

[0038] In practical use, shorter steel strips can be carried out by guide rollers, while longer strips or two rolls of steel strips can be welded together and then manually removed from the side.

[0039] The remaining parts not described in this utility model are existing or known technologies.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
