Description

Technical Field

[0001] This invention relates to the field of holding devices and their manufacturing processes, and more specifically, to a container for stacking parts and its manufacturing process. Background Technology

[0002] During production, warehousing, and logistics, parts typically require containers for centralized loading, stacking, and transfer. Existing parts containers often employ box-type, frame-type, or storage cage-type structures, using bottom load-bearing components and lateral enclosures to support and restrain the parts. For parts requiring long-distance transport or multi-layer stacking, existing structures usually need to increase the specifications of frame members, increase the density of enclosure components, or improve the welding strength of joints to ensure load-bearing and protective capabilities. While these methods can meet the requirements for parts loading and transfer to a certain extent, they tend to increase the overall weight of the container, make handling inconvenient, require more space for empty storage, and involve a large number of welding points. Furthermore, the manufacturing process relies heavily on manual assembly and welding consistency, which is detrimental to mass production and standardized management.

[0003] For example, the prior art discloses CN219858089U - a vibration-resistant, stackable storage cage, including a base plate, support columns, and side plates disposed around the perimeter of the base plate. It can be used for goods storage, transportation, and stacking, and the support columns, in conjunction with the structure, improve vibration during stacking and transportation. This type of storage cage structure illustrates that existing logistics containers have addressed stacking stability and transportation protection requirements, but their lateral enclosure and overall load-bearing capacity still primarily rely on traditional metal cage structures or mesh plate structures. For parts with small cross-sections, high stacking heights, large loading weights, and frequent turnover requirements, existing containers still fall short in balancing load-bearing strength, lateral leak prevention, ease of material retrieval, empty storage, and manufacturing efficiency. Therefore, how to reduce the container's weight, reduce storage space, improve loading and unloading convenience, and enhance batch manufacturing adaptability while meeting the requirements for parts stacking and transport strength and lateral obstruction has become a technical problem that needs to be solved in this field. Summary of the Invention

[0028] like Figure 1-4 As shown, a preferred embodiment of the present invention provides a container for stacking parts, comprising: The support module is provided with a base plate 10, a first column 11 and a second column 12. The base plate 10 is rectangular. The four corners of the base plate 10 are provided with first columns 11. The number of second columns 12 matches the number of first columns 11. The second columns 12 are provided on two mutually symmetrical side walls of the base plate 10. The second columns 12 on the same side wall are located between two first columns 11. The sidewall barrier module is provided with a first baffle 17, a barrier component 20 and a first square tube 13. Each second column 12 is provided with a first square tube 13. The barrier component 20 is provided between two second columns 12 on the same side. The first baffle 17 is provided between the first column 11 and the second column 12. The side wall movable module is provided with a second square tube 14 and a first movable baffle 40. Each first column 11 is provided with a second square tube 14. The first movable baffle 40 is provided on the symmetrical side wall of another set of base plates 10 and is movably connected to the two first columns 11. The base plate 10 is provided with a panel 15, a first base plate assembly 30 and a second base plate assembly 50, with the panel 15 arranged on the upper surface of the base plate 10. The first base plate assembly 30 is provided in two sets, which are symmetrically arranged on the lower surface of the base plate 10; Two sets of the second base plate assembly 50 are provided, which are symmetrically arranged on the lower surface of the base plate 10. The positional relationship between the two sets of the first base plate assembly 30 and the two sets of the second base plate assembly 50 can form a rectangle.

[0029] It should be noted that in this embodiment, the supporting module is used to form the basic supporting structure of the container. The base plate 10 adopts a rectangular structure, which facilitates the stacking of parts on the base plate 10 and also facilitates the arrangement of the container according to the rectangular boundary during storage and transportation. The first column 11 is set at the four corners of the base plate 10, which can provide support and limit the four corners of the container; the second column 12 is set on two mutually symmetrical side walls of the base plate 10, and is located between the two first columns 11 on the same side wall, so that the corresponding side wall has a central support position in addition to the corner support, which is beneficial to improving the installation stability of the side wall structure and reducing excessive deformation of the middle of the side wall after being squeezed by parts.

[0030] The sidewall barrier module is used to create lateral obstruction for stacked parts. A first baffle 17 is positioned between the first upright 11 and the second upright 12, effectively blocking the lateral area between the corner and the center. The barrier assembly 20 is positioned between the two second uprights 12 on the same side, blocking the central area of ​​the same sidewall, preventing stacked parts from sliding out of the container during transport. A first square tube 13 is provided in each second upright 12, serving as the mounting base for the barrier assembly 20, ensuring a relatively stable connection position for the sidewall barrier module at the second upright 12, thereby improving the assembly stability of the sidewall barrier module.

[0031] The sidewall movable module is set on another set of opposite sidewalls of the base plate 10. The first movable baffle 40 is movably connected to the two first columns 11, allowing the corresponding sidewalls to switch between a blocked state and an open state. During loading or transportation, the first movable baffle 40 can provide lateral restraint for the parts; when it is necessary to pick up or put down the parts, the first movable baffle 40 can move relative to the first columns 11, facilitating loading and unloading operations from the side. A second square tube 14 is provided in each first column 11, which can provide a connection base for the first movable baffle 40, so that the movable connection position of the first movable baffle 40 is concentrated at the first column 11, which helps to ensure the connection reliability of the first movable baffle 40.

[0032] The base plate 10 is provided with a panel 15, a first base plate assembly 30, and a second base plate assembly 50. The panel 15 is arranged on the upper surface of the base plate 10 to form a direct bearing surface when parts are stacked, so that the parts can be placed in a relatively complete support area.

[0033] Two sets of first base plate assemblies 30 are symmetrically arranged on the lower surface of the base plate 10; two sets of second base plate assemblies 50 are also symmetrically arranged on the lower surface of the base plate 10. The positional relationship between the two sets of first base plate assemblies 30 and the two sets of second base plate assemblies 50 forms a rectangle, creating a four-sided distributed support area under the base plate 10. This arrangement ensures that the support positions under the base plate 10 are not concentrated in a single direction, but rather form a relatively balanced support relationship on the lower surface of the base plate 10, which helps improve the bottom stability when containers are placed, loaded, and stacked.

[0034] Meanwhile, after the first base plate assembly 30 and the second base plate assembly 50 form a rectangular support relationship, they can be adapted to the shape of the rectangular base plate 10, making the force path at the bottom of the container clearer. After the load of the parts is transferred from the panel 15 to the base plate 10, it can be further transferred to the first base plate assembly 30 and the second base plate assembly 50; the first base plate assembly 30 and the second base plate assembly 50 then provide support for the entire container. Thus, the base plate 10, the panel 15, the first base plate assembly 30 and the second base plate assembly 50 together constitute a layered load-bearing structure, which not only meets the load-bearing requirements of parts stacking but also helps to improve the overall stability of the container structure.

[0035] In some embodiments of this application, the first base plate assembly 30 includes three first connecting posts 31 and a first support plate 32, wherein one end of two of the first connecting posts 31 is connected to the corresponding second column 12, and the other end is connected to the first support plate 32. One end of the third first connecting column 31 is connected to the base plate 10, and the other end is connected to the first support plate 32. The two ends of the first support plate 32 are respectively connected to two different first columns 11 on the same side of the base plate 10.

[0036] It should be noted that, in this embodiment, the first base plate assembly 30 is used to form a set of lateral support structures below the base plate 10. The first base plate assembly 30 includes a first connecting column 31 and a first support plate 32. The first connecting column 31 is disposed between the base plate 10, the second column 12 and the first support plate 32, so that the load of the parts borne above the base plate 10 and the lateral force received by the second column 12 can be transmitted to the first support plate 32, thereby improving the connection stability between the second column 12 and the bottom structure.

[0037] One end of the second column 12 is connected to one end of the first connecting column 31, and the other end of the first connecting column 31 is connected to the first support plate 32. Through the above connection method, the second column 12 is not only supported by the side of the base plate 10, but can also be further connected to the first support plate 32 through the first connecting column 31.

[0038] One end of the third first connecting column 31 is connected to the base plate 10, and the other end is connected to the first support plate 32. This allows the first support plate 32 to form an additional support point below the base plate 10, in addition to its connection with the corresponding position of the second column 12. This arrangement increases the number of connection points between the base plate 10 and the first support plate 32, making the support of the first support plate 32 on the base plate 10 more stable and reducing the possibility of the base plate 10 being partially suspended or experiencing concentrated stress.

[0039] The two ends of the first support plate 32 are respectively connected to two different first columns 11 on the same side of the base plate 10, so that the first support plate 32 can form a connecting support between the two first columns 11 along one side of the base plate 10. Thus, the first support plate 32, the two first columns 11, the second column 12 located between the two first columns 11, and the multiple first connecting columns 31 can form an integrated support relationship under and on the side of the base plate 10, improving the overall strength of the container on the same side.

[0040] In some embodiments of this application, the second base plate assembly 50 includes: a second connecting post 51 and a second support plate 52. One end of the second connecting post 51 is connected to the base plate 10, and the other end of the second connecting post 51 is connected to the second support plate 52. The two ends of the second support plate 52 are respectively connected to two different first columns 11 on the same side of the base plate 10.

[0041] It should be noted that, in this embodiment, the second base plate assembly 50 is used to form another set of lateral support structures below the base plate 10. The second base plate assembly 50 includes a second connecting post 51 and a second support plate 52. The second connecting post 51 is disposed between the base plate 10 and the second support plate 52, so that the component load borne by the base plate 10 can be transferred to the second support plate 52 through the second connecting post 51, thereby providing stable support below the base plate 10.

[0042] One end of the second connecting post 51 is connected to the base plate 10, and the other end is connected to the second support plate 52. Through this connection method, the second support plate 52 is not directly attached to the lower surface of the base plate 10, but rather forms a spaced support relationship with the base plate 10 through the second connecting post 51. This arrangement creates a clear force transmission path below the base plate 10, allowing the load on the base plate 10 to be transferred from the second connecting post 51 to the second support plate 52, which helps reduce localized stress concentration or localized subsidence of the base plate 10.

[0043] The two ends of the second support plate 52 are respectively connected to two different first columns 11 on the same side of the base plate 10, so that the second support plate 52 can connect two first columns 11 along one side of the base plate 10. The second support plate 52 not only supports the base plate 10, but also forms a connection relationship with the two first columns 11 on the same side, so that the two first columns 11 have a bottom connection foundation, which helps to improve the overall stability of the corner support on this side.

[0044] Combined with the first base plate assembly 30, two sets of first base plate assemblies 30 and two sets of second base plate assemblies 50 are respectively arranged on the lower surface of the base plate 10, forming a rectangular support relationship. The first base plate assembly 30 can cooperate with the second column 12 to form a middle support of the side wall, and the second base plate assembly 50 can cooperate with the first column 11 to form a corner support of the side, making the support position distribution under the base plate 10 more balanced. Through this structure, when the container is loaded with parts, transported, or stacked, the bottom structure can provide more stable support for the base plate 10 and each column.

[0045] In some embodiments of this application, the second column 12 is provided with a cotter pin 121, a retaining ring 122, a pin 123 and a V-groove 124. The cotter pin 121 is opened on the side wall of the second column 12, the pin 123 passes through the first square tube 13, the retaining ring 122 is provided at one end of the pin 123, the V-groove 124 is provided at one end of the second column 12, and the other pin 123 passes through the first square tube 13 and is engaged in the V-groove 124.

[0046] It should be noted that in this embodiment, the pin 123 passes through the first square tube 13 to form a connection base between the first square tube 13 and the second column 12. The retaining ring 122 is provided at one end of the pin 123, which can axially limit the pin 123, reduce the possibility that the pin 123 will come out of the first square tube 13 due to vibration during container handling, stacking or parts loading, thereby improving the stability of the connection between the first square tube 13 and the second column 12.

[0047] A V-groove 124 is provided at one end of the second column 12, and another pin 123 passes through the first square tube 13 and is engaged within the V-groove 124. Through the cooperation of the pin 123 and the V-groove 124, the first square tube 13 achieves a clear engagement position when installed at the second column 12. The V-groove 124 provides a guiding function, facilitating the pin 123's entry into the engagement position, and simultaneously limits the pin 123, preventing the first square tube 13 from shifting its position under stress. Thus, the first square tube 13 can maintain its connection to the second column 12 via the pin 123, and also achieve positioning and support through the cooperation of the pin 123 and the V-groove 124.

[0048] The cotter pin 121 is used to prevent the corresponding connection from coming loose, so that the pin 123 or the parts that mate with the pin 123 are not easy to come loose during use. For container structures that need to be repeatedly assembled, disassembled, folded or unfolded, the cotter pin 121 is used in conjunction with the retaining ring 122 to ensure the reliability of the connection while maintaining a certain degree of ease of disassembly and assembly, which is convenient for subsequent maintenance and replacement of connecting parts.

[0049] In some embodiments of this application, the barrier component 20 includes a second baffle 22 and a second movable baffle 23, which are connected by a hinge 21, and the second baffle 22 is connected to the panel 15.

[0050] It should be noted that in this embodiment, the barrier component 20 consists of a second baffle 22 and a second movable baffle 23. The second baffle 22 is connected to the panel 15, enabling it to function as a fixed blocking part in the barrier component 20, forming a stable barrier over the lower or middle area between the two second pillars 12 on the same side. After the parts are stacked on the panel 15, the second baffle 22 can cooperate with the adjacent first baffle 17 to laterally limit the parts, reducing the possibility of parts sliding out from the side of the container. The second baffle 22 is fixed to the panel 15 by welding.

[0051] The second movable baffle 23 is connected to the second baffle 22 via a hinge 21, allowing the second movable baffle 23 to move relative to the second baffle 22. When the container is in a loading or transporting state, the second movable baffle 23 and the second baffle 22 together form a lateral barrier; when it is necessary to assist in picking up or putting down parts from the side, the second movable baffle 23 can change its position via the hinge 21, thereby increasing the side operating space and facilitating the picking up and putting down of stacked parts.

[0052] Furthermore, the second movable baffle 23 is not at the same height as the first baffle 17, creating a height difference between them. This design aims to provide space for the first base plate assembly 30 and the second base plate assembly 50 of the upper container when multiple containers are stacked, allowing them to fit into their corresponding stacking positions and preventing interference between the second movable baffle 23 and the first and second base plate assemblies 30 and 50. Through this structure, the barrier assembly 20 satisfies both lateral blocking requirements and the space requirements when containers are stacked vertically.

[0053] In some embodiments of this application, the first movable baffle 40 and the second movable baffle 23 are each provided with two pins 60. The first movable baffle 40 and the second square tube 14 are movably connected by the pins 60, and the second movable baffle 23 and the first square tube 13 are movably connected by the pins 60.

[0054] It should be noted that in this embodiment, both the first movable baffle 40 and the second movable baffle 23 are provided with pins 60, which form a detachable or rotatable connection base between the movable baffle and the corresponding square tube. The first movable baffle 40 is movably connected to the second square tube 14 via the pins 60, allowing the first movable baffle 40 to change position relative to the second square tube 14; the second movable baffle 23 is movably connected to the first square tube 13 via the pins 60, allowing the second movable baffle 23 to change position relative to the first square tube 13. Thus, when the container needs to load or transfer parts, the first movable baffle 40 and the second movable baffle 23 can be in a blocking position, providing lateral restraint for stacked parts; when parts need to be picked up or placed, or when empty storage is required, the first movable baffle 40 and the second movable baffle 23 can move through the connection position via the pins 60, thereby freeing up side operating space.

[0055] Each first movable baffle 40 and each second movable baffle 23 is equipped with two pins 60, so that the connection position of the movable baffle is not concentrated at a single point, but rather through two connection points to cooperate with the corresponding square tube. This arrangement can reduce the swaying of the movable baffle around a single connection point when under force, which helps to improve the connection stability when the movable baffle is in the blocking state. For containers loaded with stacked parts, the two pins 60 can jointly bear the force generated by the lateral compression of the parts or the vibration of transportation, making it less likely for the first movable baffle 40 and the second movable baffle 23 to wobble or detach.

[0056] The first movable baffle 40 is connected to the second square tube 14, and the second movable baffle 23 is connected to the first square tube 13, so that the movable baffles at different positions form a connection foundation based on the square tubes in the corresponding columns. The above structure enables the force on the movable baffle to be transmitted to the square tube through the pin 60, and then to the corresponding column through the square tube, which helps to improve the overall stability of the cooperation between the side wall movable structure and the load-bearing module and the side wall barrier module.

[0057] In some embodiments of this application, both the panel 15 and the base plate 10 are provided with corresponding U-shaped grooves 18, and the second column 12 is disposed in the U-shaped groove 18.

[0058] It should be noted that in this embodiment, both the panel 15 and the base plate 10 are provided with corresponding U-shaped grooves 18, so that the panel 15 and the base plate 10 form corresponding vertical clearance spaces at the installation position of the second column 12. After the second column 12 is placed in the U-shaped groove 18, the second column 12 and the base plate 10 are no longer connected only by the edge of the base plate 10, but can be embedded in the corresponding groove formed by the panel 15 and the base plate 10, so that the second column 12 has a clearer installation reference.

[0059] By placing the second column 12 within the U-shaped groove 18, the position of the second column 12 can be limited during assembly using the U-shaped groove 18, reducing the offset of the second column 12 during installation and facilitating the maintenance of the relative position between the two second columns 12 on the same side wall. Since the barrier component 20 is positioned between the two second columns 12 on the same side, the stability of the second column 12 position also helps to ensure the installation position and lateral blocking range of the barrier component 20.

[0060] The U-shaped groove 18 provides partial accommodating space for the second column 12, making the connection area between the second column 12 and the base plate 10 and the panel 15 more compact. During parts stacking or transportation, when the second column 12 is subjected to lateral forces, the U-shaped groove 18 can provide a certain lateral restraint for the second column 12, which helps to reduce the lateral displacement of the second column 12 relative to the base plate 10, thereby improving the stability of the fit between the side wall barrier module and the bottom bearing structure.

[0061] In some embodiments of this application, the first movable baffle 40 is connected to the panel 15 via a hinge 21.

[0062] It should be noted that in this embodiment, the first movable baffle 40 is connected to the panel 15 via a hinge 21, allowing the first movable baffle 40 to rotate relative to the panel 15. When the container is in a loading or transporting state, the first movable baffle 40 can stand up and cooperate with the adjacent column to block the side of the base plate 10, reducing the possibility of stacked parts sliding out from the side. When it is necessary to pick up or put down parts or store them unloaded, the first movable baffle 40 can be rotated towards the panel 15 via the hinge 21, thereby making room for side operation and facilitating loading and unloading operations from the side of the container.

[0063] In some embodiments of this application, a support base 19 is provided at one end of the first column 11, and a connecting base 16 is provided at one end of the second square tube 14, with the support base 19 and the connecting base 16 being matched.

[0064] It should be noted that in this embodiment, a support base 19 is provided at one end of the first column 11, and a connecting base 16 is provided at one end of the second square tube 14. The support base 19 and the connecting base 16 are matched. The support base 19 and the connecting base 16 are mainly used for alignment and matching when the containers are stacked.

[0065] When multiple containers are stacked, the connecting base 16 can engage with the corresponding supporting base 19 to create a relatively fixed placement position between the upper and lower containers. This engagement reduces lateral misalignment caused by positional deviations when containers are stacked, ensuring a relatively stable relative position for the upper and lower containers in a stacked state.

[0066] A support base 19 is located at one end of the first column 11, and a connecting base 16 is located at one end of the second square tube 14, so that the stacking alignment position corresponds to the corner support position of the container. Therefore, during the container stacking process, the operator can more easily align the upper and lower containers and improve the stability of the stacked container.

[0067] It should also be noted that the support base 19, the first support plate 32 and the second support plate 52 are at the same height, the first square tube 13 and the second square tube 14 are at the same height, and the heights of the first movable baffle 40, the second movable baffle 23 and the first baffle 17 are all lower than the heights of the first square tube 13 and the second square tube 14, providing installation space for stacking.

[0068] See Figure 5-6 As shown, in this embodiment, the first baffle 17, the first movable baffle 40, the second baffle 22 and the second movable baffle 23 are all blocking structures on the side of the container. After a number of weight-reducing holes 70 are opened on the surface of the baffle, the material used for the baffle can be reduced while retaining the lateral blocking function, thereby reducing the weight of the baffle and the overall weight of the container.

[0069] The weight-reducing holes 70 also provide auxiliary space for lateral material handling. When parts are stacked high inside the container, operators or material handling tools can observe the position of the parts through the weight-reducing holes 70, or push or lift the parts from the side, reducing the inconvenience of handling when only handling materials from above the container. Since the weight-reducing holes 70 are distributed on the first baffle 17, the first movable baffle 40, the second baffle 22, and the second movable baffle 23, different sides of the container can provide certain observation and auxiliary material handling positions.

[0070] The weight-reduction holes 70 are formed on the surface of the baffle, mainly to balance weight reduction, material handling, and structural strength. By unevenly forming the weight-reduction holes 70, more non-through connection areas can be retained on the surface of the baffle, so that the baffle still has the necessary support area when subjected to lateral compression of parts or vibration during transportation.

[0071] See Figure 7 As shown, based on another preferred embodiment of the above embodiments, this embodiment provides a manufacturing process for a container for stacking parts, used in applying the above-described container for stacking parts, comprising: S100: The sheet metal used to form the base plate, the first column, the second column, the first baffle, the first movable baffle, the second baffle, and the second movable baffle is cut into corresponding sheet metal pieces; S200: When blanking the sheet material used to form the first baffle, the first movable baffle, the second baffle, and the second movable baffle, weight reduction holes are formed on the sheet material by laser cutting or die blanking; S300: The sheet material is heated to the hot stamping temperature in a heating furnace, and then stamped into a hot stamping part with the corresponding shape and size by a press and a die; S400: Cutting the tubing used to form the first square tube and the second square tube, and machining connecting holes on the tubing for mounting pins, bolts or cotter pins; S500: Sandblasting is performed on hot-stamped parts and pipes to remove surface stains and oxide layers; the sandblasted hot-stamped parts, pipes and connectors are assembled and welded to form load-bearing modules, side wall barrier modules and side wall movable modules, and the weld slag formed after assembly and welding is cleaned. S600: After cleaning the welding slag, the container is powder coated to obtain a container for stacked parts.

[0072] Specifically, during sheet metal cutting, the sheet metal is cut according to the unfolded dimensions of the base plate, first column, second column, first baffle, first movable baffle, second baffle, and second movable baffle, so that each sheet material has an outer contour that matches the subsequent hot stamping forming. For the sheet metal used to form the first baffle, first movable baffle, second baffle, and second movable baffle, weight-reducing holes are formed during the cutting process by laser cutting or die blanking, so that the corresponding enclosures can meet the lateral blocking function while reducing the amount of sheet metal used. For sheet material that needs to form U-shaped grooves or connecting avoidance positions, the corresponding grooves or avoidance structures can be formed simultaneously during the cutting process, thereby reducing subsequent secondary processing steps and ensuring the consistency of the hole positions, groove positions, and external dimensions of each hot stamping formed part.

[0073] After heating the sheet material to the hot stamping temperature, it is stamped using a press and a die to form the corresponding hot stamped part. The base plate, first baffle, first movable baffle, second baffle, and second movable baffle can be formed into a predetermined shape, flange structure, or reinforcing structure during the hot stamping process; the first column and second column can be formed into mounting positions that match the square tube, baffle, or connector during the hot stamping process. Processing the above-mentioned sheet materials by hot stamping allows each sheet to obtain a relatively stable formed shape, facilitating subsequent assembly and positioning according to corresponding positions, and also facilitating the batch processing of containers in a modular manner.

[0074] When cutting the pipes, the pipes are cut according to the installation lengths of the first and second square pipes within their respective columns, and connecting holes are machined on the pipes. These connecting holes are used for inserting pins, cotter pins, or other connecting pins, allowing the first square pipe to mate with the second column, and the second square pipe to mate with the first column. They also provide an installation base for the movable connection of the first and second movable baffles. The pipe holes are machined before welding to reduce positioning deviations caused by post-assembly machining.

[0075] During sandblasting, the surfaces of hot-stamped parts and pipes are cleaned to remove surface stains and oxide layers. After sandblasting, the welding contact areas of each component are cleaner, which is beneficial to improving the quality of subsequent welding; at the same time, the sandblasted surface also provides an adhesion base for subsequent powder coating treatment.

[0076] During assembly and welding, the base plate, panel, bottom plate assembly, first column, and second column are first assembled to form a load-bearing module. Then, the first square tube is installed into the second column, the first baffle and barrier assembly are assembled into the corresponding side wall positions, the second square tube is installed into the first column, and the first movable baffle is assembled into another set of symmetrical side wall positions. During assembly, pins, cotter pins, retaining rings, hinges, feet, and ankles act as connectors or positioning components, working together to form a unified structure from the load-bearing module, side wall barrier module, and side wall movable module. After welding, the weld slag in the welding area is cleaned to prevent it from affecting the rotation of the movable baffle, the insertion and removal of the pins, or the quality of the powder coating on the container surface.

[0077] During surface powder coating, the entire cleaned container undergoes a powder coating treatment, forming a protective layer on the surfaces of the base plate, columns, baffles, square tubes, and welded areas. This surface powder coating treatment improves the surface protection performance of the container during storage, transportation, and repeated loading and unloading, and maintains a consistent appearance. The aforementioned production process combines sheet metal cutting, weight-reducing hole forming, hot stamping, tube hole processing, sandblasting, assembly welding, and surface powder coating in sequence, allowing the main structural components of the container to be processed and assembled in a modular manner, thus improving production consistency.

[0078] The working process of this invention is as follows: In use, the container is first placed in the loading position, keeping the base plate 10 horizontal, and the first movable baffle 40 and the second movable baffle 23 are in the open state. The parts to be loaded are placed on the panel 15 from above or to the side of the container. After the parts are placed, the first movable baffle 40 is flipped to the corresponding side wall position and connected to the second square tube 14 through the pin 60; the second movable baffle 23 is flipped to the corresponding side wall position and connected to the first square tube 13 through the pin 60, so that the first baffle 17, the barrier component 20, the first movable baffle 40 and the second movable baffle 23 together surround the outside of the base plate 10.

[0079] After the parts are placed into the container, they are supported on the panel 15. The base plate 10, the first base plate assembly 30, and the second base plate assembly 50 below the panel 15 support the parts. The first uprights 11 are located at the four corners of the base plate 10, and the second uprights 12 are located in the middle of the opposite sidewalls of the base plate 10. The first baffle 17 is disposed between the first uprights 11 and the second uprights 12, the barrier assembly 20 is disposed between the two second uprights 12 on the same side, and the first movable baffle 40 is disposed on another set of opposite sidewalls, thereby confining the parts inside the container.

[0080] When containers need to be transferred, a forklift or transfer equipment can enter between the first base plate assembly 30 and the second base plate assembly 50 below the base plate 10, lift the container as a whole, and move it to the designated position. When containers need to be stacked, the upper container is moved above the lower container, so that the supporting base 19 and the connecting base 16 align and cooperate, thus completing the alignment and placement of the upper and lower containers.

[0081] When a part needs to be removed, disconnect the pin 60 at the first movable baffle 40 or the second movable baffle 23, causing the first movable baffle 40 or the second movable baffle 23 to flip outwards and be lowered, allowing the part to be removed from the side of the container; alternatively, the position of the part can be observed or the part can be removed through the weight reduction holes 70 on the baffle. After the part is removed, multiple empty containers can be stacked when storing them unloaded.

[0082] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of protection of this invention and its equivalents, this invention also intends to include these modifications and variations.
