Description

Technical Field

[0001] This utility model relates to the technical field, and more specifically, to a hot-dip galvanizing device for surface treatment of corrosion-resistant fasteners. Background Technology

[0002] Hot-dip galvanizing is a conventional anti-corrosion and anti-rust process for fasteners. In existing technologies, such as the literature with application number CN202122512038.5, due to the limitations of the galvanizing drum structure, the unloading operation after galvanizing requires clamping by an external heavy-duty mechanism, which is cumbersome and cannot meet the needs of high-speed production. Therefore, it is necessary to make a galvanizing drum with a simple structure that can quickly release the workpiece. Utility Model Content

[0003] To address the above deficiencies, this utility model provides a hot-dip galvanizing device for surface treatment of corrosion-resistant fasteners, thus solving the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hot-dip galvanizing apparatus for surface treatment of corrosion-resistant fasteners includes a zinc bath, a conveyor belt, a main beam, and a fastener body, and further includes;

[0006] The telescopic cylinder can move horizontally along the main beam;

[0007] The motor is located at the telescopic end of the telescopic cylinder.

[0008] The support assembly is used to support the fastener body. The support assembly can rotate and move in the horizontal and vertical planes. The support assembly is located at the rotating end of the motor.

[0009] The extension of the telescopic cylinder causes the load-bearing component to move downwards. During the downward movement, the load-bearing component is subjected to external force to release the fastener body.

[0010] Furthermore, it also includes an arc-shaped rod installed at the rotating end of the motor, with the upper end of the bearing assembly hinged to the arc-shaped rod, and a first circular hole opened on the surface of the bearing assembly.

[0011] Furthermore, including the winch, the external force on the bearing component is the upward pulling force generated by the winch. The working end of the winch is equipped with an iron hook, and the lower end of the bearing component is equipped with a C-shaped rod. The iron hook can hook the C-shaped rod, causing the bearing component to tilt during the downward movement, thereby tilting and releasing the fastener body. The bearing component is a first cylinder with an open upper end and a closed lower end, and a first circular hole is provided on the surface of the first cylinder.

[0012] Furthermore, the external force on the bearing component is the upward reaction force generated by the bearing component resisting the conveyor belt during the downward movement. The bearing component includes a second cylinder with openings at both the top and bottom. Pins are installed on both sides of the second cylinder. A conical cover is provided at the center of the second cylinder. A conical base is provided at the lower end of the conical cover. The conical base can close or open the lower end of the second cylinder.

[0013] Rectangular plates are fixedly installed on both sides of the conical base. J-shaped holes are opened on the rectangular plates. The pin passes through the J-shaped holes. When the pin is in the position of the barb at the lower end of the J-shaped hole, it can support and fix the conical base, so that the conical base closes the opening at the lower end of the second cylinder. When the pin is in the position of the upper end of the J-shaped hole, the conical base opens the opening at the lower end of the second cylinder, allowing the fastener body to pass through. The first circular hole is provided on the surface of the conical cover and the second cylinder.

[0014] Furthermore, the J-shaped hole is divided into a straight section and a sloping section. The lower ends of the straight section and the sloping section are connected, and the upper end of the sloping section is a stress concentration point.

[0015] Furthermore, a zinc liquid recovery cylinder is installed on the zinc pool, and a supporting component can pass through the zinc liquid recovery cylinder from top to bottom. An arc-shaped scraper is installed at the lower end of the supporting component.

[0016] The beneficial effects of this utility model are: through the function of the bearing component, the fastener body can be quickly released, simplifying the operation process and adapting to high-speed production;

[0017] Through the function of the second embodiment of the bearing component, the workpiece can be automatically released;

[0018] By setting up the conical shroud, the speed at which the zinc liquid penetrates the fastener body can be accelerated, and the fastener body can be moved away from the rotation axis of the second cylinder, thus avoiding the problem of insufficient centrifugal force at the rotation axis position, which would lead to excessively long centrifugation time.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] This application provides a hot-dip galvanizing apparatus for surface treatment of corrosion-resistant fasteners. Please refer to [reference needed]. Figures 1-4 The system includes a zinc tank 1, a conveyor belt 2, a main beam 3, and a fastener body 4, as well as a telescopic cylinder 5, which can move horizontally along the main beam 3.

[0026] Motor 6 is located at the telescopic end of telescopic cylinder 5;

[0027] The bearing component 7 is used to support the fastener body 4. The bearing component 7 can rotate and move in the horizontal and vertical planes. The bearing component 7 is located at the rotating end of the motor 6.

[0028] The extension of the telescopic cylinder 5 causes the bearing component 7 to move downward. During the downward movement, the bearing component 7 is released by external force to release the fastener body 4.

[0029] In practical applications, the motor 6 and telescopic cylinder 5 can move horizontally along the main beam 3, and the bearing component 7 can move vertically and horizontally. The bearing component 7 is initially located on the conveyor belt 2. After manual operation, the fastener body 4 can be placed in the bearing component 7. The bearing component 7 can be immersed in the zinc bath 1 for galvanizing. After a certain period of time, the galvanizing operation is completed, and the bearing component 7 is moved to the position on the conveyor belt 2 for unloading.

[0030] After the galvanizing operation is completed, directly above the zinc bath 1, the motor 6 is controlled to rotate, driving the bearing component 7 to rotate, and using centrifugal force to throw off the zinc liquid on the surface of the fastener body 4.

[0031] Reference Figure 1 , Figure 2 It also includes an arc-shaped rod 61 installed at the rotating end of the motor 6, the upper end of the bearing assembly 7 is hinged to the arc-shaped rod 61, and the surface of the bearing assembly 7 has a first circular hole 62.

[0032] In practical applications, the arc-shaped rod 61 facilitates the rotation and unloading of the bearing component 7, and the first circular hole 62 facilitates the passage of molten zinc, allowing the molten zinc to quickly contact the surface of the fastener body 1.

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The bearing assembly 7 is provided with a winch 71. The external force on the bearing assembly 7 is the upward pulling force generated by the winch 71. The working end of the winch 71 is provided with an iron hook 72. The lower end of the bearing assembly 7 is provided with a U-shaped rod 73. The iron hook 72 can hook the U-shaped rod 73, causing the bearing assembly 7 to tilt during the downward movement, thereby tilting and releasing the fastener body 4. The bearing assembly 7 is a first cylinder 74 with an open upper end and a closed lower end. The first round hole 62 is provided on the surface of the first cylinder 74.

[0034] In practical applications, after galvanizing, during the process of falling above the transmission belt 2, the iron hook 72 is manually hooked onto the shaped rod 73. At this time, as the telescopic cylinder 5 continues to extend, the first cylinder 74 gradually tilts under the action of gravity until the first cylinder 74 is in a state of downward tilting with the opening down, so that the tension generated by the release fastener body 4 and the winch 71 does not overlap with the gravity of the first cylinder 74.

[0035] Reference Figure 1 , Figure 3 and Figure 4 The external force on the bearing component 7 is the upward reaction force generated by the bearing component 7 against the conveyor belt 2 during the downward movement. The bearing component 7 includes a second cylinder 81 with openings at both the top and bottom. Pins 82 are installed on both sides of the second cylinder 81. A conical cover 83 is provided at the center of the second cylinder 81. A conical base 84 is provided at the lower end of the conical cover 83. The conical base 84 can close or open the lower end of the second cylinder 81.

[0036] A rectangular plate 85 is fixedly installed on both sides of the conical base 84. A J-shaped hole 86 is opened on the rectangular plate 85. The pin 82 passes through the J-shaped hole 86. When the pin 82 is in the position of the barb at the lower end of the J-shaped hole 86, it can support and fix the conical base 84, so that the conical base 84 closes the opening at the lower end of the second cylinder 81. When the pin 82 is in the position of the upper end of the J-shaped hole 86, the conical base 84 opens the opening at the lower end of the second cylinder 81, allowing the fastener body 4 to pass through. The first round hole 62 is provided on the surface of the conical cover 83 and the second cylinder 81.

[0037] In practical applications, when the fastener body 4 requires the conical base 84 to bear the load, the pin 82 is located at the lower end of the J-shaped hole 86. This position can stably seal the opening at the lower end of the second cylinder 81 by the conical base 84, thus providing stable load bearing.

[0038] After galvanizing, the second cylinder 81 moves to a position directly above the conveyor belt 2. When the conical base 84 contacts the conveyor belt 2, the telescopic cylinder 5 continues to extend, causing relative movement between the second cylinder 81 and the conical base 84. The pin 82 moves downward relative to the J-shaped hole 86. Through the action of the inclined section 862, the pin 82 moves to the position of the straight section 861. Then, the telescopic cylinder 5 is controlled to shorten. At this time, the pin 82 can move to the uppermost position of the J-shaped hole 86. That is to say, the rectangular plate 85 and the conical base 84 can leave the position of the lower opening of the second cylinder 81. A large space is formed between the conical base 84 and the second cylinder 81. Due to the inclined setting of the upper surface of the conical base 84, the fastener body 4 can smoothly roll out from the conical base 84.

[0039] After release, the telescopic cylinder 5 extends, moving the pin 82 to the lowest position of the J-shaped hole 86. Then, by manually rotating the conical base 84 while the telescopic cylinder 5 shortens, the pin 82 returns to its original position.

[0040] By setting the conical cover 83, the speed at which the zinc liquid penetrates the fastener body 4 can be accelerated, and the fastener body 4 can be moved away from the rotation axis of the second cylinder 81, thus avoiding the problem of insufficient centrifugal force at the rotation axis position, which would lead to excessively long centrifugation time.

[0041] Reference Figure 1 , Figure 3 and Figure 4 The J-shaped hole 86 is divided into a straight section 861 and a slanted section 862. The lower ends of the straight section 861 and the slanted section 862 are connected, and the upper end of the slanted section 862 is a stress concentration point.

[0042] In practical applications, further description of the J-hole 86 will help staff understand its function.

[0043] Reference Figure 1 , Figure 2 A zinc liquid recovery cylinder 9 is installed on the zinc pool 1, and a bearing component 7 can pass through the zinc liquid recovery cylinder 9 from top to bottom. An arc-shaped scraper 91 is installed at the lower end of the bearing component 7.

[0044] In practical applications, the zinc liquid recovery cylinder 9 can block the zinc liquid thrown out by the bearing component 7 and allow it to flow directly into the zinc pool 1 under the action of gravity. The arc-shaped scraper 91 can scrape the inner wall of the zinc liquid recovery cylinder 9 as the bearing component 7 moves, preventing the zinc liquid from solidifying on the inner wall of the zinc liquid recovery cylinder 9.
