Description

Technical Field

[0001] The utility model relates to the technical field of metal processing surface treatment, in particular to a universal sling for a swing flybar of a nickel wire. Background Art

[0002] In mechanical surface treatment, especially in electroless nickel plating, a uniform coating on the workpiece surface is crucial for ensuring machining quality. However, in practice, when workpieces, especially those with complex structures such as blind holes, are immersed in the electroless nickel plating bath, bubbles are easily trapped within the blind holes. If the workpiece remains stationary during the nickel plating process, these bubbles are difficult to expel, resulting in uneven coating distribution in these areas, which in turn reduces the overall quality and performance of the product.

[0003] To address this issue, the swinging flybar is an effective device widely used in chemical nickel plating production lines. It uses a pneumatic motor to drive the workpiece to swing back and forth in the bath, helping to expel bubbles and thus improving the uniformity of the coating. However, the traditional swinging flybar lifter design has significant limitations. Its lifting holes are fixed in position and lack flexibility. Each workpiece with different shapes and lifting hole positions requires a custom lifter, which not only increases manufacturing costs but also prolongs production preparation time and significantly reduces production efficiency.

[0004] Furthermore, traditional slings often utilize a single material and structure, making them difficult to adapt to a wide range of workpiece thicknesses and lifting requirements, limiting their versatility and practicality. Furthermore, during high-speed swinging, if the connection between the sling and the workpiece is not secure, it can easily loosen or even fall off, posing a potential threat to production safety and product quality.

[0005] In summary, existing swing flybar slings have significant deficiencies in versatility, flexibility, and safety. A new, efficient, and universal sling design is urgently needed to address these issues and improve the overall efficiency and processing quality of electroless nickel plating production lines. It is against this backdrop that this utility model proposes a universal swing flybar sling for electroless nickel production lines. Through its innovative structural design, this sling aims to achieve flexible slinging of workpieces of varying shapes and lifting positions, while also improving the sling's service life and connection stability. Utility Model Content

[0006] In order to solve the above problems, the utility model provides a universal sling for the swinging flybar of nickel-plated wire. The universal sling for the swinging flybar of nickel-plated wire realizes the height adjustability of the sling in the vertical and horizontal directions by designing multiple groups of vertical oblong notches that match the through holes at both ends of the cross bar, as well as transverse oblong notches arrayed in the horizontal direction on the cross bar. This design enables the sling to be suitable for workpieces of various shapes and different lifting positions, without the need to customize a special sling for each workpiece, which greatly enhances the versatility and flexibility of the sling, reduces manufacturing costs, shortens production preparation time, and improves production efficiency.

[0011] The crossbar fastener assembly also includes a cotter pin a, which is set in the tail end hole of the hexagonal bolt with a hole. The tail end of the cotter pin a is bent and connected to the slotted nut a to prevent the nut from loosening and the bolt from falling off due to movement.

[0012] The workpiece fastener assembly includes a raising stud, a gasket and a nut. The two ends of the raising stud are external thread structures, and an external hexagonal structure is provided in the middle position. One end of the raising stud is connected to the lifting threaded hole on the workpiece through threaded cooperation, and the other end of the raising stud is passed through the horizontal oblong notch on the cross bar and fastened with a nut. A gasket is provided between the nut and the cross bar.

[0013] A conical chamfer is provided on a side of the outer hexagonal structure at the middle position of the raised stud close to the workpiece.

[0014] A through hole is machined on the side of the external thread structure of the raised stud away from the workpiece to install the cotter pin b. A flat washer b is used as the gasket and a slotted nut b is used as the nut. The tail end of the cotter pin b is bent and connected to the slotted nut b to prevent the nut from loosening and the bolt from falling off due to movement.

All metal workpieces should be made of 304 stainless steel or titanium alloy.

[0029] The boom a1 and boom b4 are symmetrical structures. A pad is welded on the top of the boom a1 to improve the structural strength of the boom a1 hoisting position. Three groups of notches are set on the side of the boom. All the notches have the same size (the notch length is set to c, c≤50mm). Each group of notches is arrayed in the vertical direction (the array spacing is d=2*c). The three groups of notches have the same horizontal spacing.

Notches are set on the top of the boom a1 and boom b4, and pads a are set on the sides of the notches. 12 and pad b13, the pad a12 and pad b13 are made of POM material, with high structural strength and wear resistance, the pad a12 is a T-shaped structure on the side, an oblong with an open bottom, a semicircular top, a stopper in the middle, and a tapered countersunk hole on the side. The pad a12 is inserted into the notches of the hanger a1 and the hanger b4, and fastened with countersunk screws on the side; a group of through holes are processed on each side of the cross bar 5, and each group of through holes is a 3*3 structure. The vertical spacing of the through holes is d, and the horizontal spacing is the same as the horizontal spacing of the notches of the hanger a1.

[0030] Two groups of slots are respectively provided at the upper and lower positions on the side of the crossbar 5, with a slot length of e, an array spacing of f=2*e, and an offset spacing of the two groups of slots of e; the two groups of slot arrays are symmetrical structures, wherein the number of slots in the upper group is an odd number, and the number of slots in the lower group is an even number; the two ends of the raised stud are external thread structures, and the middle position is an external hexagonal structure, the external hexagonal structure is tapered chamfered close to the workpiece side, and a through hole is processed on the side of the external thread structure away from the workpiece for installing a cotter pin.

[0031] The external hexagonal structure in the middle of the raised stud makes it easy to install and tighten using a wrench, and the tapered chamfer design close to the workpiece surface not only avoids poor processing caused by covering the workpiece surface, but also simplifies the installation process and improves work efficiency.

[0032] The pads a and b arranged in the slots above the hanger a and the hanger b are made of POM material, which has high strength, wear resistance and corrosion resistance, and avoids friction between the pin shaft and metal parts. All metal workpieces are made of 304 stainless steel, which increases the service life of the utility model; the spacing between the hanger a and the hanger b can be adjusted by changing the length of the shaft sleeve, which can adapt to a variety of workpieces of different thicknesses.
