Description

Technical Field

[0001] This utility model relates to the field of flux-cored welding wire technology, and in particular to a flux-cored welding wire roll forming device. Background Technology

[0002] Flux-cored welding wire, also known as powder-cored welding wire or tubular welding wire, is divided into two main categories: gas-shielded and non-gas-shielded. Like solid welding wire, the surface of flux-cored welding wire is made of materials with good plasticity, such as low-carbon steel or low-alloy steel. In the production of flux-cored welding wire, the rolling forming process has a significant impact on product quality and performance.

[0003] Existing roll forming equipment is not only difficult to apply to the production of flux-cored welding wires of different specifications, but also, during roll forming, debris and impurities on the surface of the flux-cored welding wire are easily left in the rolling groove. If these impurities are not removed in time, they will easily have an adverse effect on the quality of subsequent welding wire processing, making it difficult to meet the production requirements of high-precision flux-cored welding wires.

[0030] Example 2:

[0031] Please see Figures 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: a pre-compression mechanism 2 is provided on the base plate 1. The pre-compression mechanism 2 includes a housing 201, which is fixedly connected to the base plate 1. A servo motor 202 is fixedly connected to the rear side wall of the housing 201. A driving gear 203 and a driven gear 204 are rotatably connected to the inner wall of the housing 201. The driving gear 203 and the driven gear 204 are meshed together. The output end of the servo motor 202 is fixedly connected to the driving gear 203. The front side wall of the driving gear 203... A pre-pressure roller 205 is fixedly connected, and a pre-pressure roller 206 is fixedly connected to the front side wall of the driven gear 204. Both the pre-pressure roller 205 and the pre-pressure roller 206 are provided with pre-tightening grooves. The left and right side walls of the housing 201 are provided with through grooves 207. The front side wall of the housing 201 is hinged with a door 208. The left and right side walls of the housing 201 are fixedly connected with guide plates 3. The guide plates 3 are located outside the through grooves 207. Before the flux-cored welding wire enters the rolling mechanism 6, its body passes through the through grooves 207 of the housing 201 and is pre-pressed by the pre-pressure mechanism 2.

[0032] In this implementation scheme, during operation, the servo motor 202 is started to drive the drive gear 203 to rotate. The drive gear 203 drives the driven gear 204 to rotate, which in turn drives the pre-pressure roller 205 and the second pre-pressure roller 206 to rotate synchronously in opposite directions. The flux-cored wire is subjected to pre-pressure between the pre-pressure roller 205 and the second pre-pressure roller 206, so that the flux-cored wire is initially compacted and its shape is adjusted before entering the rolling mechanism 6, which prepares it for subsequent precise rolling. The guide plate 3 is located outside the through groove 207 and plays a role in guiding the flux-cored wire to accurately enter the pre-pressure mechanism 2, so as to avoid the wire from deviating when entering. After the operation is completed, the inside of the box 201 can be inspected and maintained by opening the box door 208. The pre-treatment of the flux-cored wire by the pre-pressure mechanism 2 can greatly improve the accuracy of subsequent rolling and forming, and improve production efficiency and product quality.

[0033] Working principle: During operation, the flux-cored welding wire to be processed is placed in the starting position. Servo motor 25 is started to drive the lead screw 9 to rotate. The lead screw 9 drives the lifting frame 601 to move up and down along the inner side of the fixed frame 4, adjusting the working height of the roller 607. After the position is adjusted, servo motor 3603 is started to drive the rotating rod 606 to rotate. The meshing of the driving gear 2604 and the driven gear 2605 drives the two rotating rods 606 to rotate synchronously in opposite directions, thereby driving the two rollers 607 to rotate in opposite directions. When the flux-cored welding wire passes through the rollers 607, the groove 610 rolls it, gradually achieving the predetermined shape and size. During the rolling process, the scraper blade 705 can scrape the inner wall of the groove 610 to ensure that the groove 610 is clean and smooth. No impurities remain, ensuring a clean working environment and effectively improving the rolling forming quality of flux-cored welding wire. During the pre-pressing of the flux-cored welding wire, the servo motor 202 is started to drive the drive gear 203 to rotate. The drive gear 203 drives the driven gear 204 to rotate, which in turn drives the pre-pressing roller 205 and the pre-pressing roller 206 to rotate synchronously in opposite directions. The flux-cored welding wire is pre-pressed between the pre-pressing roller 205 and the pre-pressing roller 206, so that the flux-cored welding wire is initially compacted and its shape is adjusted before entering the rolling mechanism 6, preparing it for subsequent precise rolling. After the work is completed, the inside of the box 201 can be inspected and maintained by opening the box door 208. The pre-treatment of the flux-cored welding wire by the pre-pressing mechanism 2 can greatly improve the accuracy of subsequent rolling forming.

[0034] 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.
