Description

Technical Field

[0001] The utility model belongs to the technical field of hot-dip galvanizing, in particular to a hot-dip galvanizing hanger with the function of reducing contact with workpieces. Background Art

[0002] Hot-dip galvanizing hangers are tools specially used to support and fix workpieces during the hot-dip galvanizing process. It is usually made of high-temperature resistant and corrosion-resistant materials to ensure stability and durability when used in high-temperature zinc liquid. The design of these hangers needs to take into account the fixation of the workpiece, the circulation of zinc liquid, and the uniformity of the coating. Existing hot-dip galvanizing hangers have the problem of a large contact area with the workpiece during use. This contact will make it difficult to cover the part where the hanger contacts the workpiece with a uniform zinc layer, resulting in coating quality problems. Secondly, the coating at the contact point is thinner, which is more prone to corrosion during use, reducing the durability of the workpiece. The conventional response method is to improve the hanger design and reduce the contact area with the workpiece to minimize uneven coating and zinc accumulation. However, the disadvantage of this design is that although it can reduce the contact point, it may cause the workpiece to be loosely fixed and increase the risk of falling. In addition, the complex design will increase the manufacturing and maintenance costs of the hanger, so it is hoped that a new structure will be proposed to solve the above problems.

[0035] Example 1: Please refer to Figure 1 and Figure 2When it is necessary to perform hot-dip galvanizing on some workpieces with special shapes (for example, large and heavy workpieces that are difficult to hang, the disassembly and assembly vertical rod 140 and the disassembly and assembly hanging plate 150 are in an installed state), the hanging blocks of the first group of workpieces 160 are placed on the top of the left and right groups of hanging grooves 230 at the rear side of the two groups of disassembly and assembly hanging plates 150, the hanging blocks of the second group of workpieces 160 are placed on the top of the two middle groups of hanging grooves 230, and the hanging blocks of the third group of workpieces 160 are placed on the top of the two front groups of hanging grooves 230. Since the left and right sides of the workpieces 160 are not It contacts the inner side of the outer frame 100, and the width of the workpiece 160 is smaller than the spacing length between the front and rear groups of hanging grooves 230. Therefore, only the bottom of the hanging block of the workpiece 160 contacts the hanging groove 230 inside the hanger, and the workpiece body is in a suspended state. Therefore, the contact area between the hanger and the workpiece 160 can be effectively reduced to prevent the coating on the surface of the workpiece body from being too thin, which leads to quality problems. At the same time, multiple groups of workpieces 160 can be hung inside the hanger at the same time, which is convenient for further processing of multiple groups of workpieces 160 at one time, thereby improving work efficiency.

First, pinch the front edge of the disassembly hanging plate 150 on the right side of the fixed cross bar 110 and pull it forward, so that the disassembly sliding bar 240 slides forward inside the disassembly sliding groove 190 until the disassembly hanging plate 150 on the left is completely pulled out, and remove the disassembly hanging plate 150 on the far right according to the above steps, so as to remove the disassembly hanging plate 150 inside the fixed cross bar 110, and then pinch the disassembly hanging plates 150 on both sides of the fixed cross bar 2 120 from left to right in sequence and pull them forward, so that the disassembly sliding bar 240 slides forward inside the disassembly sliding groove 220 and pulls out, until the disassembly hanging plate 150 is completely pulled out, and remove the remaining disassembly hanging plates 150 in turn, thereby completing the disassembly of all disassembly hanging plates 150;

[0037] The second tightening bolt 200 is then rotated to make the bottom of the tightening bolt 200 rotate upward and disengage from the inside of the mounting groove 210, thereby releasing the fixing effect between the fixed cross bar 220 and the disassembly vertical rod 140, and then gently pull the disassembly vertical rod 140 forward to make the top of the disassembly vertical rod 140 offset from the position below the fixed cross bar 220, and then lift the disassembly vertical rod 140 upward to remove a group of disassembly vertical rods 140, and remove the remaining disassembly vertical rods 140 in sequence according to the above steps, thereby completing the disassembly of all disassembly vertical rods 140 (tightening bolt 170 is used to reinforce the fixed cross bar 110 and the fixed cross bar 2 120, thereby ensuring the stability of the outer frame 100, thereby ensuring the overall stability of the hanger, and no disassembly is required), and then it is convenient to carry out and replace the disassembly hanging plate 150 and the disassembly vertical rod 140, thereby ensuring the stability and reliability of the hanger, and facilitating maintenance.
