Description

Technical Field

[0001] This utility model belongs to the field of welding wire preparation technology, and specifically relates to a pressing device for preparing aluminum alloy welding wire. Background Technology

[0002] Currently, the steel strip method is commonly used to produce flux-cored welding wire. This method uses cold-rolled steel strip as the outer sheath material, which is cut into narrow strips, cleaned, and then cold-bent into U-shaped tubes. Flux powder is added, and the strip is closed into an O-shaped tube, which is then drawn multiple times. The U-shaped tube is often formed by extrusion rollers. Two concave rollers are placed vertically side-by-side, and the steel strip is extruded through the rollers to form a U-shaped tube with an open top. However, this device is not adjustable and can only produce U-shaped tubes of fixed sizes. Therefore, an adjustable pressure block device for aluminum alloy welding wire preparation is designed to adjust the extrusion rollers for the U-shaped tube. Utility Model Content

[0003] The purpose of this invention is to provide a pressing device for preparing aluminum alloy welding wire, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pressing device for preparing aluminum alloy welding wire, comprising a frame, a feeding roller on the frame, a pre-forming roller on one side of the feeding roller, a U-shaped extrusion roller on one side of the pre-forming roller, guide blocks at the upper and lower ends of the U-shaped extrusion roller, a fixed plate movably connected to the guide blocks, and linkage devices on both sides of the fixed plate, the linkage devices comprising a worm gear, a connecting rod connected to the guide blocks, a worm wheel on one side of the connecting rod, the worm wheel matching the worm gear, a right-angle drive connected to the upper end of the worm gear, the right-angle drives on both sides being connected by a transmission rod, and a turntable on the upper side of one right-angle drive.

[0005] Preferably, the guide block has grooves on both sides, and the edge of the fixing plate is disposed in the grooves.

[0006] Preferably, the linkage device is provided with an outer casing.

[0007] Preferably, the feed roller is configured as two planar rollers.

[0008] Preferably, a bearing is provided on the guide block, and the end of the U-shaped extrusion roller is connected inside the bearing.

[0009] Preferably, a frame connecting plate is provided on the outer side of the fixing plate, and the frame connecting plate is mounted on the frame.

[0010] Preferably, one end of the worm gear passes through a right-angle transmission and is connected to a turntable.

[0011] The technical effects and advantages of this utility model are as follows: The pressing device for preparing aluminum alloy welding wire uses a pre-forming roller to initially bend the steel strip, which facilitates subsequent U-shaped extrusion forming.

[0012] A linkage device is set up, along with a right-angle drive, so that the U-shaped extrusion rollers on both sides can move inward or outward at the same distance simultaneously. This allows for adjustment of the distance between the U-shaped extrusion rollers while ensuring accurate and symmetrical adjustment, avoiding the asymmetry that occurs with manual adjustment.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] This utility model provides, for example Figure 1-3 The device for preparing aluminum alloy welding wire includes a frame 1, on which a feeding roller 2 is provided. The feeding roller 2 consists of two flat rollers that feed the steel strip. A pre-forming roller 3 is provided on one side of the feeding roller 2. Several groups of pre-forming rollers 3 are arranged horizontally. Each group consists of a convex roller and a concave roller to perform preliminary bending on the passing steel strip.

[0019] A U-shaped extrusion roller 4 is provided on one side of the preforming roller 3. Several sets of U-shaped extrusion rollers 4 are arranged vertically. A concave groove is provided on the U-shaped extrusion roller 4. The initially bent steel strip enters the U-shaped extrusion roller 4 and is squeezed to form a U-shape with an open top. The flux core used for flux-cored welding wire is added through the open top. Guide blocks 6 are provided at the upper and lower ends of the U-shaped extrusion roller 4. Bearings are provided on the guide blocks 6. The ends of the U-shaped extrusion roller 4 are connected to the bearings. Sliding grooves 12 are provided on both sides of the guide blocks 6. The edge of the fixing plate 5 is set in the sliding grooves 12, so that the guide blocks 6 can move along the fixing plate 5. A frame connecting plate is provided on the outer side of the fixing plate 5. The frame connecting plate is mounted on the frame 1.

[0020] Both sides of the fixed plate 5 are equipped with linkage devices, each including a worm gear 9. The guide block 6 is connected to a connecting rod 11, and a worm wheel 10 is provided on one side of the connecting rod 11. The worm wheel 10 matches the worm gear 9. By rotating the worm gear 9, the U-shaped extrusion rollers 4 on the same side can be moved inward or outward simultaneously to achieve spacing adjustment. The upper end of the worm gear 9 is connected to a right-angle transmission device 8. The right-angle transmission device 8 is equipped with two bevel gears to achieve right-angle transmission. One end of the worm gear 9 passes through the right-angle transmission device 8 and is connected to a turntable 14. The right-angle transmission devices 8 on both sides are connected by a transmission rod 13, so that rotating the turntable 14 and transmitting power through the right-angle transmission devices 8 on both sides can achieve simultaneous inward or outward movement of the U-shaped extrusion rollers 4 by an equal distance. This avoids the possibility of different movement distances that may occur with manual adjustment, which could cause the centers of the two U-shaped extrusion rollers 4 and the center of the preforming roller 3 to be on the same plane, making it easy for the steel strip to twist after being pressed into a U-shape. This ensures smooth forming.

[0021] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
