Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy saving and environmental protection, in particular to an energy saving and environmental protection type stainless steel cabinet production method. BACKGROUND

[0002] In the technical field of custom-made home, the conventional way is to prepare custom-made cabinet boards by using plywood or multi-layer laminated boards, and then assemble the custom-made cabinet boards to obtain custom-made home.

[0003] The custom-made home obtained by such process and technical means realizes the reuse of leftover materials, which is good for resource saving and utilization, and has low cost compared with solid wood boards. However, the boards prepared by this method, whether particle boards or multi-layer boards, need to add a large amount of glue solution during preparation to ensure the integrity and firmness of the prepared boards. Even after the boards are prepared, a glue film paper needs to be attached to the surface of the boards, and the preparation of the glue film paper also needs to add glue solution or other preparations. The glue solution and the glue film paper are both sources of formaldehyde, and the release of formaldehyde is slow and long-term, which needs to be removed in a ventilated environment for a period of time, which is not conducive to environmental protection and health.

[0004] In order to solve this problem and realize full utilization of resources and reduce formaldehyde release, the existing technology solves the above problems by preparing a stainless steel cabinet. On the one hand, stainless steel can be recycled and reused, and on the other hand, the board prepared by stainless steel has almost no formaldehyde release, and even does not involve formaldehyde problem, so this scheme is more conducive to the current requirements for health and environmental protection.

[0005] However, the existing stainless steel custom-made home board needs to use aluminum honeycomb reinforcement in the preparation process. The structural strength of this board is guaranteed, but it brings trouble to recycling. Because the stainless steel custom-made home board is usually welded at the joint after being prepared and formed, and after welding, the outer surface is made of stainless steel material and the inner part is filled with aluminum honeycomb. Stainless steel and aluminum honeycomb cannot be recycled together, and need to be disassembled and recycled separately. The existing stainless steel cabinet board prepared by this method is not conducive to recycling. SUMMARY

[0006] The present application overcomes the shortcomings of the prior art and provides an energy saving and environmental protection type stainless steel cabinet production method, which overcomes the problems existing in the prior art,

[0007] In one aspect of the present application, an energy saving and environmental protection type stainless steel cabinet production method is provided, comprising the steps of:

[0008] S10, cutting; cutting the inner frame plate, the middle plate and the outer frame plate on the same piece or the same batch of stainless steel mother plate according to the predetermined size;

[0009] S20, synchronous molding; stacking and aligning the middle plate on the inner frame plate, and stacking and aligning the outer frame plate on the middle plate; placing the inner frame plate on the lower mold, and simultaneously molding the three plates to obtain the nested inner frame body, the middle frame body and the outer frame body;

[0010] S30, edge rolling; disassembling and separating the inner frame body from the middle frame body, and placing a support assembly in the inner frame body to obtain an inner frame assembly; edge rolling the two side edge portions of the inner frame body in the length direction to form a curling portion along the length direction, and the two curling portions are respectively arranged on the two sides of the inner frame body;

[0011] S40, welding; welding and fixing the joint seam of the outer frame body, and welding and fixing the middle frame body and the outer frame body;

[0012] S50, assembling; buckling the inner frame body on the middle frame body, and the opening of the inner frame body faces the bottom surface of the middle frame body to obtain a cuboid cabinet plate.

[0013] In a further technical solution, in step S10, the inner frame plate is cut, and the two sides of the inner frame plate in the length direction form a wide strip, and the two sides of the inner frame plate in the width direction form a narrow strip;

[0014] In step S30, the two side edge portions of the inner frame body in the length direction are edge rolled, including: curling the wide strip to obtain a curling portion with a spiral cross section, the axis of the curling portion is consistent with the length direction of the inner frame plate; and the outer diameter of the curling portion is greater than the thickness of the inner frame body, so that the curling portion is elastically deformed when the inner frame body is assembled with the middle frame body.

[0015] In a further technical solution, in step S20, after the middle plate is stacked on the inner frame plate, point gluing is performed; after the outer frame plate is stacked on the middle plate, point gluing is performed;

[0016] The simultaneous molding of the three plates includes: first pressing the middle part of the three plates by the upper mold, and then molding the straight edge strip on the side edge of the three plates to correspondingly form the frame structure.

[0017] In a further technical solution, the support assembly includes a corrugated plate made of stainless steel, the corrugated plate is fixed in the inner frame body, and the thickness of the corrugated plate is equal to the depth of the inner frame body.

[0018] Further technical solutions, the support assembly includes a stainless steel pipe, a plurality of steel pipes are arranged in parallel in the inner frame body, and the length direction of the steel pipe is consistent with the length direction of the inner frame body.

[0019] Further technical solutions, the support assembly is cut from the same stainless steel mother plate as the inner frame plate and is obtained by machining.

[0020] Further technical solutions, before step S40, further comprising step S30A, the intermediate frame body is split with the outer frame body, and the middle part of the intermediate frame body is molded to process at least one arch part; the arch part is matched and fastened with the support assembly during assembly.

[0021] Further technical solutions, before step S40, further comprising step S30B, cutting a reinforcing rib from the same stainless steel mother plate as the inner frame plate, the reinforcing rib is assembled on the intermediate frame body; and a plurality of limiting grooves are formed on the reinforcing rib to cooperate with the assembly of the support assembly, so that the support assembly is stably assembled on the intermediate frame body.

[0022] Further technical solutions, in step S50, after the inner frame body is buckled on the intermediate frame body, the splicing seam of the inner frame body and the intermediate frame body is fixed by laser welding.

[0023] The beneficial effects of the energy-saving and environment-friendly stainless steel cabinet production method are as follows:

[0024] 1) When preparing the large plate, it is obtained from the same stainless steel mother plate, so the materials of the three large plates are uniform; specifically, the inner frame plate, the intermediate plate and the outer frame plate can be prepared from the same material; thereby ensuring the uniformity of the material of the three large plates. Further, the material of the prepared cabinet plate is uniform, which can be directly recycled without disassembly or classification, reducing the recycling process and reducing the recycling difficulty. Therefore, in the field of environmental protection technology, it is a feasible and effective scheme.

[0025] 2) Synchronously mold the three large plates to ensure the tightness of assembly. On the one hand, stack the three large plates together, and then mold simultaneously, which does not have great difficulty in processing, but requires high precision in cutting the size of the large plate before processing. Accurate large plate size can ensure the size of the frame body after molding. On the other hand, synchronous molding can ensure that the sizes of the frame bodies formed by the same group of large plates are consistent, thereby accurately buckling and tightly fitting when assembled. In addition, synchronous molding saves energy and improves processing efficiency.

[0026] 3), compared with the prior art, the cabinet plate prepared by the method of the present application does not set aluminum honeycomb, so the hollow part between the outer frame and the inner frame needs to adopt a reinforced structure. In the present application, on the one hand, the side edge part of the inner frame is curled to obtain a curling part, so as to improve the structural strength and support strength of the two sides of the inner frame in the length direction. On the other hand, the support assembly is arranged to strengthen and improve the stability. Compared with the prior art, the curling part can improve the structural strength and support effect of the side edge of the inner frame, and generally a hole needs to be opened at this position, which can avoid the problem of poor structural stability caused by the opening; the curling part also has the effect of supporting the inner frame and the middle frame, and the curling parts abut on the inner frame and the middle frame respectively, so that the inner frame and the middle frame are relatively separated and are not easy to collapse relatively.

[0027] 4), compared with the prior art, a middle frame is further arranged, so that the four side walls of the whole cabinet plate form a multi-layer structure. The stability of the side wall is strengthened, and the middle frame is stacked with the outer frame, so that the outer frame has a double-layer structure on one side, and the surface structural strength of the outer frame is greater and the stability is better, and the thickness direction is not easy to collapse. As for the length direction and the width direction of the whole cabinet plate, the support stability in the length direction and the width direction is ensured due to the adoption of the multi-layer structure. In addition, the middle frame can also be subjected to die pressing processing to process a specific shape and play the role of a reinforcing rib or a rib. In this way, the uniformity and flatness of the whole cabinet plate are ensured, and the support strength and anti-deformation ability of the internal structure are also ensured.

[0028] 5), welding and fixing, and snap-fit assembly, so that the prepared cabinet plate has good overall uniformity and flatness. The cabinet plate prepared by the method of the present application has a cuboid structure, and the surface is neat and uniform, which is beneficial to application in customized home and is beneficial to ensuring the appearance and uniformity of the obtained home product.

[0029] 6), without sheet metal slotting. BRIEF DESCRIPTION OF DRAWINGS

[0041] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0042] In the attached diagram, Figure 7 and Figure 8 The supporting components in them have different structural forms. Figure 1 This is a general overview of the process of the present invention. Figures 2-11 These are schematic diagrams of the product obtained at each stage of the present invention.

[0043] Please see Figures 1-11 The energy-saving and environmentally friendly stainless steel cabinet production method of the present invention includes the following steps:

[0044] S10. Cutting: Cut the inner frame plate, middle plate, and outer frame plate into the specified dimensions from the same piece or batch of stainless steel mother plate.

[0045] Specifically, before cutting the stainless steel mother plate, the shape and dimensions of the large plate to be processed need to be drawn in a computer or control system. The cut and formed intermediate large plate has a main body and four side parts surrounding the main body. During molding, the four side parts are bent and perpendicular to the main body. The width of the four side parts of the intermediate large plate is equal, but the lengths of the four side parts are the same in pairs. Similarly, the outer frame large plate also has a main body and four side parts. Likewise, the side parts can be bent relative to the main body. Likewise, the width of the four side parts of the outer frame large plate is the same, and the lengths of the side parts are the same in pairs. The intermediate large plate is different; the width and length of the four side parts of the intermediate large plate are unequal; and the lengths of the side parts of the intermediate large plate are equal in pairs, and their widths are also equal in pairs. In other words, among the four side parts of the intermediate large plate, two are wider and two are narrower in terms of width.

[0046] S20, Synchronous molding; The middle large plate is stacked and aligned on the inner frame large plate, and then the outer frame large plate is stacked and aligned on the middle large plate; The inner frame large plate is placed on the lower mold, and the three large plates (the three large plates refer to the inner frame large plate, the middle large plate, and the outer frame large plate) are molded at the same time to obtain the nested inner frame, middle frame, and outer frame.

[0047] Before molding, the three large plates are stacked and stabilized to ensure accuracy during molding. During stacking, they are placed one by one: first, the inner frame plate is placed on the lower mold, and then its position is adjusted to ensure accurate alignment; next, the middle plate is placed on top of the inner frame plate, and its alignment is adjusted to ensure it is centered; finally, the outer frame plate is placed on top of the middle plate, and its alignment is adjusted to ensure it is centered. During molding, the upper mold moves downwards from above the outer frame plate. The downward pressure of the molding first acts on the outer frame plate, and then the outer frame plate sequentially transfers the force to the middle and inner frame plates, so that the outer, middle, and inner frame plates are molded simultaneously. The benefits of this approach are, firstly, saving time and effort by completing the molding of three large panels simultaneously using the same set of molding equipment and molds; secondly, ensuring consistent and coordinated dimensions to guarantee high precision and fit in subsequent assembly; and finally, this processing method is environmentally friendly, producing no toxic or harmful substances.

[0048] In some preferred embodiments, in step S20, after the middle large plate is stacked on the inner frame large plate, it is applied with adhesive; after the outer frame large plate is stacked on the middle large plate, it is applied with adhesive.

[0049] The simultaneous molding of three large plates includes pressing the middle of the three large plates with an upper mold first, and then molding the sides of the three large plates to form right-angled edge strips, so as to form a corresponding frame structure.

[0050] When applying adhesive, use a spot-applying method, and immediately mold the adhesive after application to prevent it from hardening. Before the adhesive hardens, complete the molding process, disassemble the individual panels, and ideally remove all remaining adhesive.

[0051] Alternatively, in some preferred embodiments, during molding, the upper mold first presses down on the center of the outer frame panels to press the three panels firmly onto the lower mold. Then, the edge of the upper mold continues to press down, causing the edges of the three panels to form the side walls of the frame. In this embodiment, the adhesive is applied in dots to prevent misalignment of the three panels during simultaneous molding.

[0052] S30, Rolling edges; Disassemble and separate the inner frame from the middle frame, and place a support component in the inner frame to obtain the inner frame component; Roll the two side edges of the inner frame along its length to form a rolled portion along its length, with the two rolled portions placed on both sides of the inner frame respectively.

[0053] The rolled edge is crucial for the implementation of this invention. In this invention, only two sides of the inner frame are rolled, and these two sides are located along the length of the inner frame. Thus, the axis of the resulting rolled portion is along the length of the inner frame. This strengthens the structural strength of the inner frame, making it less prone to collapse and providing a stable support between the inner frame and the intermediate frame, preventing collapse of either. Furthermore, it strengthens the sides of the inner frame and ensures the strength of the sides of the prepared cabinet, maintaining the strength of the cabinet sides even during subsequent drilling. It also improves the support effect along the length of the inner frame and even the cabinet itself; when the cabinet is placed vertically along its length, the two rolled portions act as side support columns. Since this invention eliminates the need for aluminum honeycomb, the rolled portion becomes particularly important. Moreover, because the rolled portion and the inner frame are an integral structure, the consistency of material, the seamless connection, and the structural integrity make the board material obtained by this invention more suitable for use in customized furniture.

[0054] In some preferred embodiments, in step S10, an inner frame plate is cut out, with wide strips formed on both sides of the inner frame plate in the length direction and narrow strips formed on both sides of the inner frame plate in the width direction.

[0055] In step S30, the step of rolling the two side edges of the inner frame along its length includes: rolling the wide strip to obtain a rolled part with a spiral cross-section, the axis of which is consistent with the length direction of the inner frame plate; and the outer diameter of the rolled part is greater than the thickness of the inner frame, so that when the inner frame is assembled with the middle frame, the rolled part is squeezed and elastically deformed.

[0056] In some preferred embodiments, the support assembly includes a corrugated plate made of stainless steel (e.g., Figure 7 or Figure 8 As shown, the corrugated plate is fixed in the inner frame, and the thickness of the corrugated plate is equal to the depth of the inner frame.

[0057] In some other preferred embodiments, the support assembly comprises a stainless steel pipe (not shown, but may be referenced). Figure 7 and Figure 8 Multiple steel pipes are arranged in parallel within the inner frame, with the length direction of the steel pipes aligned with the length direction of the inner frame.

[0058] In some preferred embodiments, the support components are made from the same stainless steel mother plate or from the same batch as the inner frame plate, and are manufactured through processing.

[0059] In some preferred embodiments, before step S40 and after step S30, step S30A is further included: separating the intermediate frame and the outer frame, and molding the middle part of the intermediate frame to form at least one arched part; the arched part is fastened to the support component during assembly.

[0060] In some preferred embodiments, before step S40 and after step S30A, step S30B is also included: cutting out reinforcing ribs from the same stainless steel mother plate as the inner frame plate, and assembling the reinforcing ribs onto the middle frame; and opening multiple limiting grooves on the reinforcing ribs to cooperate with the assembly of the support components, so that the support components are stably assembled onto the middle frame.

[0061] In some further embodiments, the reinforcing ribs are welded and fixed to the intermediate frame, and then assembled onto the support assembly; in other further embodiments, the reinforcing ribs are welded and fixed to the support assembly, and then abut against the bottom surface of the intermediate frame. (See attached diagram.) Figure 8 The example shown illustrates the assembly relationship between the reinforcing ribs and the support components.

[0062] S40. Welding; welding to fix the splicing seams of the outer frame, and welding to fix the middle frame to the outer frame.

[0063] In this invention, laser welding is used for welding, and spot welding can be selected.

[0064] S50. Assembly: Attach the inner frame to the middle frame, with the opening of the inner frame facing the bottom of the middle frame, to obtain a rectangular cabinet panel.

[0065] In some preferred embodiments, in step S50, after the inner frame is fastened to the middle frame, the joint between the inner frame and the middle frame is fixed by laser welding.

[0066] Some advantages of the energy-saving and environmentally friendly stainless steel cabinet production method of the present invention:

[0067] 1) The large panels are made from the same stainless steel base plate, ensuring uniformity in material for all three panels. Specifically, the inner frame panel, middle panel, and outer frame panel are all made from the same material, guaranteeing material consistency. This uniformity results in cabinet panels that can be directly recycled without disassembly or sorting, reducing recycling steps and difficulty. Therefore, this is a feasible and effective solution in the field of environmental protection.

[0068] 2) Simultaneous molding of the three large panels ensures a tight assembly. Firstly, stacking the three large panels together and molding them simultaneously is not particularly difficult in terms of processing, but it requires high precision in the pre-cut dimensions of the large panels. Accurate panel dimensions ensure the final frame size after molding. Secondly, simultaneous molding ensures that the frames formed from the same set of large panels have consistent dimensions, resulting in accurate and tight fitting when assembled. Thirdly, simultaneous molding saves energy and improves processing efficiency.

[0069] 3) Compared to existing technologies, the cabinet panel prepared by the method of this invention does not have aluminum honeycomb, so the hollow part between the outer frame and the inner frame needs to be reinforced. In this invention, on the one hand, the side edges of the inner frame are rolled to obtain a rolled portion, thereby improving the structural strength and support strength of both sides of the inner frame in the length direction. On the other hand, the support components are set to strengthen and improve stability. Compared to existing technologies, the rolled portion improves the structural strength and support effect of the side edges of the inner frame, and usually, an opening is needed at this position, which avoids the problem of poor structural stability caused by the opening; the rolled portion also supports the inner frame and the middle frame, with the rolled portion abutting against the inner frame and the middle frame respectively, so that the inner frame and the middle frame are relatively separated and not easily collapse.

[0070] 4) Compared to existing technologies, an additional intermediate frame layer is incorporated, creating a multi-layered structure on all four side walls of the cabinet panel. This enhances the stability of the side walls. The stacking of the intermediate and outer frames results in a double-layered structure on one side of the outer frame, leading to greater surface strength, improved stability, and reduced likelihood of collapse in the thickness direction. Furthermore, the multi-layered structure ensures stable support along both the length and width of the cabinet panel. Additionally, the intermediate frame can be molded to create specific shapes and function as reinforcing ribs or struts. This ensures both a uniform and flush appearance of the entire cabinet panel and robust internal structural support and resistance to deformation.

[0071] 5) Welding and fastening assembly ensure that the prepared cabinet panel has good overall uniformity and a smooth shape. The cabinet panel prepared by the method of this invention has a rectangular structure with a neat and uniform surface, which is beneficial for application in customized furniture and ensures the aesthetics and uniformity of the resulting furniture products.

[0072] 6) No need for sheet metal grooving. Compared to existing bending techniques, grooving is required when bending stainless steel to ensure accuracy. However, in this invention, bending is performed through molding and the sheet metal is rolled by edge curling, eliminating the need for grooving. This is a feature of the process scheme according to this invention, resulting in a product with no grooving marks on the surface and better overall consistency. This avoids the decrease in bending and compressive strength caused by stress concentration and improves support strength, making it more suitable for use in cabinet panel processing.

[0073] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
