Description

Technical Field

[0001] This utility model relates to the field of forging technology, specifically to a corrosion-resistant stainless steel forging. Background Technology

[0002] Stainless steel forgings are widely used in critical fields with stringent material performance requirements, such as petrochemicals, marine engineering, nuclear power, aerospace, and medical devices, due to their excellent mechanical properties (such as high strength and high toughness) and good corrosion resistance. In particular, under harsh working conditions such as high temperature, high pressure, and strong corrosive media, the corrosion resistance of forgings directly determines the service life and operational safety of equipment.

[0003] After production and before use, the protection of forgings during packaging, storage and transportation is crucial. In current practice, forgings are often directly stacked in cargo compartments or transported using simple wooden pallets and fixed racks. Existing technology has obvious shortcomings in this regard: on the one hand, there is a lack of effective moisture protection, especially during long-distance transportation in rainy seasons or humid environments. The humidity inside the cargo compartment is high, and moisture in the air easily condenses on the surface of the forgings. Although stainless steel itself has a certain degree of corrosion resistance, long-term exposure to a humid and enclosed environment will still cause surface rust or water stains. For precision forgings, even slight rust may require additional cleaning and polishing, which not only increases subsequent maintenance costs and time, but may even lead to customer rejection due to appearance issues.

[0004] On the other hand, the protection methods are limited and cannot be disassembled. The common protection methods are simply applying rust-preventive oil or covering the entire surface with a simple tarpaulin. While applying rust-preventive oil can provide some protection, it requires thorough cleaning before delivery, which adds to the process. Tarpaulins have poor sealing properties, limited moisture protection, and cannot prevent bumps and collisions during transportation. Existing technologies lack corrosion-resistant protection mechanisms that can be tightly integrated with forgings and can be quickly disassembled. Utility Model Content

[0005] The purpose of this invention is to provide a corrosion-resistant stainless steel forging with advantages such as good moisture resistance, impact resistance, and quick disassembly and assembly of the protective mechanism, thus solving the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A corrosion-resistant stainless steel forging includes a stainless steel forging body, a support plate placed at the lower end of the stainless steel forging body, a protective shell placed at the upper end of the support plate, a first groove opened at the upper end of the protective shell, an outer protective cylinder fixed to the bottom surface of the inner wall of the first groove, a plurality of limiting cylinders fixed to the bottom surface of the inner wall of the first groove, a plurality of limiting posts fixed to the upper end of the support plate, a rubber cylinder placed on the inner wall of the outer protective cylinder, and a plurality of through holes opened at the lower end of the protective shell. A protective mechanism for protecting the stainless steel forging body is provided at the upper end of the stainless steel forging body, and a handle is fixedly connected to the upper end of the protective mechanism. A cylindrical groove is provided at the upper end of the stainless steel forging body, and the inner wall of the rubber cylinder is in contact with the side wall of the stainless steel forging body. The upper end of the limiting post passes through the through hole and extends to the inner wall of the limiting cylinder.

[0007] Preferably, both the tray and the protective shell are hexagonal structures, with the outer peripheral surfaces of the tray and the protective shell being flush.

[0008] It is worth noting that the pallet and protective shell adopt a hexagonal structure with flush outer circumference. Compared with a circle, the hexagonal structure is less prone to rolling. When stacked, the edges can limit each other, which greatly improves the stacking stability. The flush outer circumference ensures that multiple forgings fit tightly when stacked, which can save storage and transportation space. At the same time, it avoids relative displacement caused by shaking during transportation, which can reduce collision damage and achieve safer and more efficient storage and transportation.

[0009] Preferably, ventilation slots are provided through the lower part of each side wall of the protective shell, and second slots for gripping are provided through the upper part of each side wall of the protective shell.

[0010] It is worth noting that the lower part of the protective shell sidewall is provided with a ventilation slot and the upper part with a second slot. The advantage is that the ventilation slot can promote the air circulation between the inside of the protective shell and the outside, timely discharge of humid air, reduce internal humidity, and effectively reduce the risk of floating rust or water stains on the surface of the forging due to moisture. The second slot provides a convenient gripping point for handling, which is convenient for manual or mechanical handling.

[0011] Preferably, the height of the rubber sleeve is higher than the height of the outer protective sleeve.

[0012] It is worth noting that the rubber sleeve is taller than the outer protective sleeve. The taller rubber sleeve can form a more comprehensive enclosure around the connection between the stainless steel forging body and the protective mechanism, enhancing the coverage of the sealing protection and effectively preventing external moisture, dust and other impurities from entering through gaps, thus improving the overall protection effect on the forging.

[0013] Preferably, the height of the outer casing is equal to the height of the protective shell.

[0014] It is worth noting that the height of the outer casing is equal to the height of the protective shell. The uniformity of their heights forms a unified support and protection plane, making the support force of the outer casing on the forging and the protection force of the protective shell more evenly distributed. This avoids localized stress concentration caused by height differences and enhances the overall structural stability.

[0015] Preferably, one end of the outer casing has a uniformly distributed reinforcing block fixed to its side wall, and the other end of the reinforcing block is fixed to the inner wall of the protective shell.

[0016] It is worth noting that the outer casing sidewall is connected to the inner wall of the protective shell by evenly distributed reinforcing blocks. The advantage is that the reinforcing blocks can firmly connect the outer casing and the protective shell into a whole, enhancing the structural strength and impact resistance of the two. When the transport is bumpy or subjected to external force collision, the impact force can be effectively dispersed, preventing the outer casing and the protective shell from loosening or deforming, thus extending the service life of the protective mechanism.

[0017] Preferably, the protective mechanism consists of a first mounting cover placed on the upper end of the stainless steel forging body and an inner protective cylinder fixed to the lower end of the first mounting cover. The side wall of the inner protective cylinder is in contact with the inner wall of the stainless steel forging body, the side wall of the first mounting cover is in contact with the inner wall of the rubber cylinder, and the lower end of the handle is fixed to the upper end of the first mounting cover.

[0018] It is worth noting that the protective mechanism consists of a first mounting cover and an inner protective sleeve. The inner protective sleeve is fitted to the inner wall of the forging, and the first mounting cover is fitted to the inner wall of the rubber sleeve. The double-fit structure can form multiple seals, which can further prevent moisture intrusion. At the same time, the placement connection method does not require complicated operation, and can realize the quick assembly and disassembly of the protective mechanism, which can reduce loading and unloading time.

[0019] Preferably, the protective mechanism includes a second mounting cover threaded onto the inner wall of the rubber cylinder, the upper end of the second mounting cover being fixedly connected to the lower end of the handle.

[0020] It is worth noting that the protective mechanism uses a threaded second mounting cover. The advantage of this is that the threaded connection has good sealing and stability, can fit tightly against the inner wall of the rubber cylinder, and can effectively prevent moisture from seeping in. At the same time, the threaded structure makes the disassembly and assembly process simple and convenient, which can be completed by simply rotating it, making it easy to quickly inspect or remove the forgings.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By fitting the inner wall of the rubber cylinder to the side wall of the stainless steel forging body, and with the height of the rubber cylinder being higher than the outer protective cylinder, the connection between the forging and the protective mechanism can be fully wrapped, effectively preventing external moisture and dust from entering through the gaps. At the same time, the ventilation groove at the bottom of the protective shell side wall can promote internal air circulation, timely discharge of humid air, and reduce internal humidity. The combination of the two can prevent the forging from developing floating rust or water stains in a humid environment, reduce subsequent cleaning and maintenance costs, and solve the defects of insufficient moisture protection in the existing technology. 2. The protective mechanism adopts two quick-disassembly structures: First, the first mounting cover is placed so that the inner protective cylinder fits against the inner wall of the forging and itself fits against the inner wall of the rubber cylinder, which can be installed and removed without complicated operations. Second, the second mounting cover is connected to the inner wall of the rubber cylinder by threads, and can be quickly installed and removed by rotation, which can be adapted to different usage scenarios. 3. The pallet and protective shell are hexagonal in structure with flush outer circumference. When stacked, they are mutually restrained by the edges. Combined with the design of the limiting post passing through the through hole and inserting into the limiting cylinder, the relative displacement during transportation can be restricted. The outer protective cylinder is connected to the inner wall of the protective shell by the reinforcing block, which can enhance the overall impact resistance and effectively prevent the forgings from being damaged by bumps and collisions.

[0025] To address the problem of stainless steel forgings lacking effective moisture protection and physical safeguards during packaging, storage, and transportation, thus easily becoming corroded and damaged by impacts, the following technical solution is provided. Please refer to [the provided text]. Figures 1-7 ; A corrosion-resistant stainless steel forging includes a stainless steel forging body 1, a support plate 2 placed at the lower end of the stainless steel forging body 1, a protective shell 3 placed at the upper end of the support plate 2, a first groove 4 opened at the upper end of the protective shell 3, an outer protective cylinder 5 fixed to the bottom surface of the inner wall of the first groove 4, a plurality of limiting cylinders 6 fixed to the bottom surface of the inner wall of the first groove 4, a plurality of limiting posts 7 fixed to the upper end of the support plate 2, a rubber cylinder 10 placed on the inner wall of the outer protective cylinder 5, and a plurality of through holes 15 opened at the lower end of the protective shell 3. A protective mechanism for protecting the stainless steel forging body 1 is provided at the upper end of the stainless steel forging body 1, and a handle 14 is fixedly connected to the upper end of the protective mechanism. A cylindrical groove is provided at the upper end of the stainless steel forging body 1, and the inner wall of the rubber cylinder 10 is in contact with the side wall of the stainless steel forging body 1. The upper end of the limiting post 7 passes through the through hole 15 and extends to the inner wall of the limiting cylinder 6.

[0026] In use, the stainless steel forging body 1 is placed on the upper end of the pallet 2, and the protective shell 3 is placed on the upper end of the pallet 2, so that the upper end of the limiting post 7 passes through the through hole 15 and extends to the inner wall of the limiting cylinder 6. The rubber cylinder 10 is placed on the inner wall of the outer protective cylinder 5, so that the inner wall of the rubber cylinder 10 fits against the side wall of the stainless steel forging body 1. Then, the protective mechanism is installed on the upper end of the stainless steel forging body 1, which can provide closed protection for the stainless steel forging body 1. The pallet 2, the protective shell 3 and the outer protective cylinder 5 are all made of corrosion-resistant materials, which can effectively protect the stainless steel forging body 1 during transportation.

[0027] In this embodiment, specifically: both the tray 2 and the protective shell 3 are hexagonal structures, and the outer peripheral surfaces of the tray 2 and the protective shell 3 are flush.

[0028] In this embodiment, specifically: ventilation slots 8 are provided through the lower part of each side wall of the protective shell 3, and second slots 9 for gripping are provided through the upper part of each side wall of the protective shell 3.

[0029] In this embodiment, specifically, the height of the rubber sleeve 10 is higher than the height of the outer protective sleeve 5.

[0030] In this embodiment, specifically, the height of the outer casing 5 and the height of the protective shell 3 are equal.

[0031] In this embodiment, specifically: one end of a uniformly distributed reinforcing block 16 is fixed to the side wall of the outer casing 5, and the other end of the reinforcing block 16 is fixed to the inner wall of the protective shell 3.

[0032] Example 1: In this example, the protective mechanism consists of a first mounting cover 11 placed on the upper end of the stainless steel forging body 1 and an inner protective cylinder 12 fixed to the lower end of the first mounting cover 11. The side wall of the inner protective cylinder 12 is in contact with the inner wall of the stainless steel forging body 1, the side wall of the first mounting cover 11 is in contact with the inner wall of the rubber cylinder 10, and the lower end of the handle 14 is fixed to the upper end of the first mounting cover 11.

[0033] The inner sleeve 12 fits against the inner wall of the stainless steel forging body 1, and the first mounting cover 11 fits against the inner wall of the rubber sleeve 10 to form a double seal, which can effectively prevent water vapor from entering. The placement connection does not require complicated operation, and the protective mechanism can be quickly disassembled and assembled, reducing loading and unloading time. The handle 14 is easy to hold and improves the convenience of picking up and putting down.

[0034] Example 2: In this example, the protective mechanism includes a second mounting cover 13 threaded onto the inner wall of the rubber cylinder 10, with the upper end of the second mounting cover 13 fixed to the lower end of the handle 14.

[0035] The second mounting cover 13 is threaded to the inner wall of the rubber cylinder 10, providing strong sealing and stability, effectively preventing moisture infiltration. The threaded structure allows for easy disassembly and assembly with just a rotation operation, making the process simple and convenient. It facilitates quick inspection or retrieval of the stainless steel forging body 1. The handle 14 is designed for easy gripping, enhancing operational flexibility.

[0036] Working principle: When in use, first place the pallet 2 on a flat operating surface, then place the stainless steel forging body 1 stably on the upper end of the pallet 2, ensuring that the lower end face of the stainless steel forging body 1 is in contact with the upper end face of the pallet 2. Then take the protective shell 3 and place it on the upper end of the pallet 2, so that the multiple limiting posts 7 fixed to the upper end of the pallet 2 pass through the multiple through holes 15 opened at the lower end of the protective shell 3 and extend to the inner wall of the multiple limiting cylinders 6 fixed to the bottom surface of the first groove 4 at the upper end of the protective shell 3. Through the cooperation of the limiting posts 7 and the limiting cylinders 6, the protective shell 3 and the pallet 2 are accurately positioned and stably connected. At this time, the hexagonal outer circumference of the pallet 2 and the protective shell 3 are flush. Next, the rubber cylinder 10 is placed on the inner wall of the outer protective cylinder 5. Since the height of the rubber cylinder 10 is higher than the height of the outer protective cylinder 5 and the height of the outer protective cylinder 5 is equal to the height of the protective shell 3, the inner wall of the rubber cylinder 10 will be tightly fitted with the side wall of the stainless steel forging body 1. At the same time, the side wall of the outer protective cylinder 5 is fixed to the inner wall of the protective shell 3 through the evenly distributed reinforcing blocks 16, which can further improve the firmness of the connection between the outer protective cylinder 5 and the protective shell 3. Then, select the corresponding protective mechanism for installation according to actual needs. If the protective mechanism of Embodiment 1 is used, align the inner protective cylinder 12 fixed to the lower end of the first mounting cover 11 with the cylindrical groove opened at the upper end of the stainless steel forging body 1 and place it so that the side wall of the inner protective cylinder 12 fits against the inner wall of the stainless steel forging body 1, while the side wall of the first mounting cover 11 fits against the inner wall of the rubber cylinder 10 to complete the double seal. If the protective mechanism of Embodiment 2 is adopted, the second mounting cover 13 is installed on the inner wall of the rubber cylinder 10 by means of threads, so that the second mounting cover 13 is tightly connected to the rubber cylinder 10. After the protective mechanism is installed, the handle 14 fixed to its upper end makes it easy for operators to hold and complete the overall picking and placing actions. During the entire protection process, the ventilation slots 8 at the lower part of each side wall of the protective shell 3 can promote internal air circulation and reduce humidity. The upper second slot 9 facilitates handling operations. Furthermore, the pallet 2, the protective shell 3, and the outer protective cylinder 5 are all made of corrosion-resistant materials. Combined with the sealing effect of the rubber cylinder 10, they can provide comprehensive protection for the stainless steel forging body 1 during transportation and storage, effectively blocking moisture and dust from entering and avoiding impact damage. Through the synergistic effect of the above components, a closed protection for the stainless steel forging body 1 can be achieved.
