Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of metal pickling processing, in particular to a fastener pickling device. Background Art
[0002] During the manufacturing process of fasteners, they may form a layer of oxide scale or rust. Pickling can effectively remove these impurities and make the surface of the fastener cleaner. Before electroplating or other coating treatments, pickling can improve the adhesion of the coating to the surface of the fastener and ensure that the coating is uniform and firm. During the electroplating process, hydrogen atoms may be absorbed on the surface of the fastener, which may lead to hydrogen embrittlement, that is, tiny surface cracks are caused where stress is concentrated. Proper pickling can reduce the risk of this phenomenon. An important purpose of stainless steel pickling is to remove the oxide scale and black scale produced by high-temperature operations to expose the matrix crystallization and prepare for subsequent processes such as electroplating, coloring, etc. In this process, some waste that needs to be processed is also generated. These detached and generated wastes should be left in the pickling tank as much as possible for centralized collection. For this purpose, the application document provides a fastener pickling device.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:
[0026] See also Figure 1-6 As shown, the utility model is a fastener pickling device, comprising a pickling tank 1, a servo motor 2, an eccentric swing arm 3, a pickling basket 4 and a separation grid 5. A motor mounting seat 6 for mounting the servo motor 2 is fixed to one side of the pickling tank 1. A seat bearing 7 is fixed to the other side of the pickling tank 1. The eccentric swing arm 3 is mounted on the output shaft of the servo motor 2 and the seat bearing 7. The pickling basket 4 is mounted on the eccentric swing arm 3. The separation grid 5 is placed at the bottom of the pickling tank 1.
[0027] The eccentric swing arm 3 includes a round rod 31 for mounting the pickling basket 4. A pair of connecting plates 32 are symmetrically fixed at both ends of the round rod 31. A shaft sleeve 33 and a short shaft 34 are fixed on the outer sides of the two connecting plates 32, and the shaft sleeve 33 and the short shaft 34 are coaxially arranged. The shaft sleeve 33 is connected to the output shaft of the servo motor 2, and the shaft sleeve 33 and the output shaft of the servo motor 2 are fixed by a key pin. The short shaft 34 is installed on the seat bearing 7.
[0028] Among them, two ring sleeves 35 are fixed on the round rod 31 through top screws. An annular groove 36 is opened in the middle of the ring sleeve 35.
[0029] The pickling basket 4 includes a semicircular trough body 41. The semicircular trough body 41 has a row of arc-shaped drain holes 42 along its axial direction. The arc outer wall of the semicircular trough body 41 is fixed with multiple layers of horizontally arranged spoilers 43, and the ends of the multiple layers of spoilers 43 are fixed with sealing plates 44. A chain hook 45 is fixed to the outer walls at both ends of the semicircular trough body 41. The hook body of the chain hook 45 is hung in the annular groove 36. A second hook 46 is fixed to the upper end of the hook body of the chain hook 45. The second hook 46 is used for lifting and mounting by a crane or other lifting equipment in the workshop.
[0030] The separation grid 5 includes a mesh plate 51 . A row of support strips 52 are fixed to the lower surface of the mesh plate 51 , and the support strips 52 are arranged parallel to the round rods 31 .
[0031] Specific implementation process: First, put the fasteners to be pickled into the pickling basket 4, and then use the crane to mount the pickling basket 4 on the eccentric swing arm 3. Start the servo motor 2, so that its output shaft drives the eccentric swing arm 3 to swing back and forth in the washing tank 1, and then drives the pickling basket 4 to swing in the pickling tank 1. The pickling basket 4 is always kept below the acid in the semicircular trough 41, so that the fasteners are fully in contact with the pickling liquid, thereby improving the pickling effect. The eccentric swing arm 3 is driven by the servo motor 2 to realize the reciprocating swing of the pickling basket 3 in the washing tank 1. During the swinging process, the multi-layer spoiler 43 guides the acid to the fasteners in the pickling basket 3, so that the fasteners are fully in contact with the pickling liquid and take away the fallen residue, thereby improving the pickling effect.
[0032] After the pickling is completed, the servo motor 2 is turned off, and the pickling basket 4 is taken out by a crane to obtain a fastener with a clean surface. At the same time, the detached and generated waste will be concentrated on the separation grid 5 for centralized collection and treatment. The separation grid 5 is designed so that the detached and generated waste can enter the bottom of the mesh plate 51, and a row of support slats 52 divides the space below into multiple independent parts to reduce the range of residue movement, so that it is convenient to concentrate at the bottom of the pickling tank for centralized collection and treatment.
