Description

Technical Field

[0001] The present invention relates to the technical field of metal parts conveying, and more particularly to a conveying device for metal processing products which is convenient for collecting defective products. Background Art

[0002] Metal processing products refer to the transformation of metal materials into items or parts with specific shapes, sizes and properties through various processing techniques. These processes cover a variety of methods from basic cutting and welding to more complex forging and die-casting, and are widely used in industrial manufacturing, architectural decoration, household goods, and art production. Defective products are metal products that have failed the inspection, and conveyors are needed to collect defective products.

[0003] Chinese patent application number CN202410003241.5 discloses a metal parts mold processing parts conveying device, which belongs to the field of conveying control technology. It includes a base plate, and four first support legs are fixedly connected to the upper surface of the base plate. The upper surfaces of the four first support legs are commonly fixedly connected to two first brackets. The interiors of the two first brackets are commonly rotatably connected to two first rollers. The outer surfaces of the two first rollers are commonly sleeved with a first conveyor belt. The left side of one of the first brackets is fixedly connected to a first rotating motor, and the power output end of the first rotating motor passes through the first bracket and is fixedly connected to the left end of one of the first rollers. The metal parts mold processing parts conveying device uses a camera to shoot an image of the metal parts mold on the first conveyor belt and compare it with the image of a qualified mold for detection. The rotation of the drive motor causes the guide rack to move up and down, thereby removing unqualified molds. This not only improves the detection efficiency, but also saves time and effort, and greatly reduces the labor intensity of workers.

[0004] In the metal processing industry, metal tubular parts are one of the common processing objects. Traditional metal pipe conveying equipment usually only has a simple conveying function and cannot realize the rotation of the metal pipe during the conveying process, resulting in the detection equipment only being able to detect part of the surface of the metal pipe, affecting the overall quality of the metal pipe products. Defective metal pipes are mixed with qualified metal pipes, and the same batch of metal pipes need to be re-conveyed and re-tested multiple times, increasing the complexity and cost of subsequent processes.

The slider 23 matches and slides with the slide groove 22, ensuring that the slip ring 6 slides stably on the surface of the conveying rod 5.

[0034] When the gear 9 moves following the conveying rod 5, the gear 9 meshes with the toothed plate 15. As the transmission chain 4 continues to convey, the gear 9 rotates and drives the metal tube 12 to rotate in the conveying frame 11. As the conveying rod 5 continues to move, the gear 9 rotates and drives the bearing 8 to rotate in the rotating groove 7, so that the rotating ring 10 rotates and drives the friction pad 13 to rotate. The rotation of the friction pad 13 causes the metal tube 12 to rotate in the conveying frame 11. At this time, the visual image detector 16 works to perform a comprehensive inspection of the surface of the metal tube 12.

[0035] The use steps of the present invention are as follows: when the conveying device for metal processed products which is convenient for collecting defective products is used, before conveying the metal tube 12, the metal tube 12 is placed in order between the two conveying racks 11 through the existing orderly loading equipment, and then the motor 21 works to drive the transmission chain 4 to rotate, and the transmission chain 4 drives the conveying rod 5 to rotate.

The inside of the slot 27 is rotatably connected with a rotating plate 29 for squeezing the ball head 26. According to the length of the metal tube 12 to be transmitted as needed, the adjustment handle 30 is manually pushed so that the rotating plate 29 rotates with the rotating shaft 28. When the angle adjustment of the rotating plate 29 is completed, the transmission chain 4 drives the conveying rod 5 to rotate.

The Z-shaped frame 25 and the ball head 26 move with the slip ring 6. When the ball head 26 is squeezed by the rotating plate 29, the two Z-shaped frames 25 move toward each other and move with the slip ring 6, thereby making the conveying frame 11 move to the length of the metal tube 12. In order to ensure that the metal tube 12 is rotated and fully detected during the detection process, the electric telescopic rod 24 is extended to move with the movable frame 14 and the toothed plate 15, so that the position of the toothed plate 15 corresponds to the position of the gear 9, thereby increasing the functionality and practicality of the conveying device.
