It also makes the processing technology and equipment universal, and allows for free switching of shapes.

Description

Technical Field

[0001] This invention relates to the field of door manufacturing technology, and in particular to a splicing door and its manufacturing process. Background Technology

[0002] Currently, the industry standard for door panel design is to use embossing molds and weld the design on the front. This method can only achieve door panel designs with a fixed structure.

[0003] If the pattern structure needs to be changed, new pattern molds or new equipment need to be customized, which is costly and has a long production cycle. Summary of the Invention

[0004] The purpose of this invention is to provide a splicing door and its manufacturing process to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A type of modular door is available, suitable for a door body that can be hinged to a door frame. The door body includes an outer panel and an inner panel. After the outer panel and the inner panel are assembled, they form a hollow door body. The hollow part of the door body is filled with a filler. The outer panel has irregularly shaped holes. A liner plate is provided on the side of the outer panel near the inner panel that can completely cover the irregularly shaped holes. Decorative inlays are embedded in the irregularly shaped holes. The liner plate has cuts with the same outline as the irregularly shaped holes.

[0007] The filler is honeycomb paper.

[0008] The filler is an aluminum honeycomb core.

[0009] The edge of the liner is welded to the outer plate.

[0010] The non-perforated portion of the outer panel is bonded to the lining panel with sealant.

[0011] The shortest distance between the edge of the liner and the inner edge of the irregular hole is greater than 10 mm.

[0012] The decorative inlay is a stainless steel decorative inlay.

[0013] A manufacturing process for a modular door includes the following steps:

[0014] S1. Selection of backing plate: Place the decorative inlay on the backing plate. The shortest distance between the edge of the backing plate and the edge of the inlay must be greater than 10mm.

[0015] S2. After clamping the outer panel and the lining plate with tooling, use laser cutting equipment to make holes, so that the outer panel forms irregular holes with the same shape as the decorative inlay, and at the same time, concave cut marks appear on the top of the lining plate.

[0016] S3. Remove the outer panel and liner from the tooling;

[0017] S4. Apply a sealant coat between the edge of the liner and the cut.

[0018] S5. Use tooling to re-clamp the liner plate and the outer plate, and weld the edge of the liner plate to the outer plate. The irregular holes on the liner plate and the outer plate form a concave cavity.

[0019] S6. Determine whether there is any sealant overflow inside the cut. If there is an area with sealant overflow inside the cut, apply sealant to this area a second time.

[0020] S7. After the sealant has dried, remove the outer panel and liner from the fixture again.

[0021] S8. Bend the outer and inner panels to the design dimensions;

[0022] S9. Fill the inside of the inner panel with filler material and bond the filler material to the inner panel with adhesive.

[0023] S10. Assemble the inner panel and outer panel to form the door body;

[0024] S11. Apply metal adhesive evenly inside the concave cavity and insert the decorative inlay into the concave cavity.

[0025] The beneficial effects of this invention are:

[0026] With the addition of irregular holes, backing plates, cuts, and decorative inlays, only the built-in cutting path of the laser cutting equipment needs to be changed, eliminating the need for new equipment such as molds. This allows a single machine to produce decorative patterns of different shapes without the need for new equipment investment, reducing production costs and making the processing technology and equipment interchangeable, enabling free switching of shapes. At the same time, the cuts define the area for applying sealant and can also be used to determine whether sealant is present at the joints of concave cavities, ensuring complete sealing at the joints. After uniformly applying the metal adhesive, there will be no areas without metal adhesive at the bottom of the concave cavity due to external pressure, thus ensuring the bonding strength of the decorative inlays. It also prevents the adhesive inside the door from overflowing into the concave cavity, ensuring the aesthetics of the door exterior. Attached Figure Description

[0032] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0033] Please see Figures 1-4 This invention provides a modular door, see below. Figure 1 It is suitable for door 6 that can be hinged to door frame 1 via hinge 2.

[0034] See Figure 2 The door body 6 includes an outer panel 3 and an inner panel 4. After the outer panel 3 and the inner panel 4 are assembled, they form a hollow door body 6. The hollow part inside the door body 6 is filled with a filler 5. The filler 5 can be honeycomb paper, preferably aluminum honeycomb core. The biggest advantage of aluminum honeycomb core is that it can avoid the situation where the honeycomb paper gets damp and rots and smells bad.

[0035] The outer plate 3 has irregular holes made by laser cutting equipment, and the backing plate 8 is also provided with cuts 9 with the same outline as the irregular holes. The cuts 9 are generated at the same time when the laser cutting equipment makes holes in the outer plate 3.

[0036] A liner 8 is provided on the side of the outer panel 3 near the inner panel 4, which can completely cover the irregular hole. It is necessary to ensure that the shortest distance between the edge of the liner 8 and the inner edge of the irregular hole is greater than 10mm. The edge of the liner 8 is welded to the outer panel 3. The part of the outer panel 3 without through holes is bonded to the liner 8 with sealant. A decorative inlay 7 is embedded in the irregular hole. The decorative inlay 7 is made of stainless steel and can be directly installed and used without additional coating treatment.

[0037] A manufacturing process for a modular door includes the following steps:

[0038] S1. Selection of backing plate 8: Place the decorative inlay 7 on the backing plate 8. The shortest distance between the edge of the backing plate 8 and the edge of the inlay 7 must be greater than 10mm.

[0039] S2. After clamping the outer plate 3 and the liner plate 8 with tooling, use a laser cutting device to make holes, so that the outer plate 3 forms irregular holes with the same shape as the decorative inlay 7. At the same time, a concave cut 9 appears on the top of the liner plate 8. If the pattern of the decorative inlay 7 needs to be changed, only the built-in cutting path of the laser cutting device needs to be changed, and no new equipment such as molds is required.

[0040] S3. Remove the outer plate 3 and the liner plate 8 from the tooling.

[0041] S4. Apply a sealant coat between the edge of the liner 8 and the cut 9 (see...). Figure 4 The presence of cut 9 delineates the area to be coated with sealant, ensuring that sealant is present at all subsequent concave cavity joints.

[0042] S5. Use the tooling to re-clamp the liner plate 8 and the outer plate 3, and weld the edge of the liner plate 8 to the outer plate 3. The irregular holes on the liner plate 8 and the outer plate 3 form a concave cavity (although a sealant was applied once in S4, after the liner plate 8 and the outer plate 3 are assembled, there will inevitably be some gaps at the joint between the liner plate 8 and the outer plate 3, so that the sealant is not completely covered, which will affect the subsequent application of metal adhesive).

[0043] S6. Determine whether there is any overflowing sealant inside the cut 9. If there is an area where sealant has overflowed inside the cut 9, apply sealant a second time to this area. Use the cut 9 to determine whether there is sealant at all the joints of the concave cavity, and ensure that the joints of the concave cavity are completely sealed.

[0044] S7. After the sealant has dried, remove the outer panel 3 and the liner 8 from the fixture again.

[0045] S8. Bend the outer panel 3 and the inner panel 4 to the design dimensions;

[0046] S9. Fill the interior of the inner panel 4 with filler 5 and bond the filler 5 to the inner panel 4 with adhesive.

[0047] S10. Assemble the inner panel 4 and the outer panel 3 to form the door body 6;

[0048] S11. Apply metal adhesive evenly inside the concave cavity and insert the decorative inlay 7 into the concave cavity. Since the joint of the concave cavity is completely sealed, the metal adhesive cannot penetrate between the outer panel 3 and the lining panel 8. After the metal adhesive is evenly applied, there will be no area without metal adhesive at the bottom of the concave cavity due to external pressure, thus ensuring the bonding strength of the decorative inlay 7. At the same time, it also avoids the situation where the adhesive inside the door 6 overflows into the concave cavity, ensuring the aesthetic appearance of the door 6.
