Problems solved by technology

There is a large error in the flatness of the door, which makes it impossible to paint with high efficiency. It needs to enter the painting process for multiple times of painting and polishing. There are many manual uses and large fluctuations in quality
And there are internal structural processing defects that are exposed through the refraction of light after painting
Inability to achieve overall perfection
U.S. Patent No. 5,543,234 discloses a molded door with decorative molded recesses. WO0181055 discloses a molded door extended outwards by reverse molding technology. Although the manufacture of these doors solves the problems of door types and production convenience, the process Complexity, high cost, defects in assembly, and the appearance of the product is also affected to a certain extent

example 1

[0014] Example 1: Flat door

[0015] Door frame part: The door frame is processed according to the design size, and the surrounding is processed to the tolerance size. The thickness error is large, and the thickness is machined (pressed), and the thickness is sent to the sander to meet the design tolerance. Go to assembly.

[0016] Edge strip part: with UV veneer. Or use solid wood strips for four-sided planing to size, carry out UV coating three-sided roll coating and curing, and primary sand. Go to assembly.

[0017] Panel part: choose appropriate plywood (particle board, medium and high density fiberboard) as the lining board, use solid wood veneer as the panel, apply glue and hot press, cut to the design size, groove or trim the edges evenly, and enter the surface with UV line for roller coating Painting, initial sanding. Go to assembly.

[0018] Assembly: Put the panel on the surface of the door frame, use wood glue and gun nails to assemble the panel and the door fr...

[0019] Example 2: Frame Door

[0020] Frame part: Make solid wood glulam according to the design size, cut and process it to the tolerance size, the thickness error is large, carry out thickness machining (planing), and send it to the thickness-setting sander to reach the design tolerance. Heat pressed with component panels.

[0021] Component panel part: choose appropriate plywood (particle board, medium and high-density fiberboard) as the lining board, use solid wood veneer as the panel, apply glue and hot press, cut to the frame design size, trim the edges evenly, and rely on glue hot pressing with the frame parts, Carry out surface sanding, and then enter the roller coating UV line for surface coating, initial sanding, and enter assembly.

[0022] Door core board part: use plywood with a set thickness (particle board, medium and high density fiberboard) as the lining board, use solid wood veneer as the double-sided panel, apply glue and hot press, cut to the door core des...

[0024] Example 3: Metal doors covered with wooden materials

[0025] When the steel structure material is used inside and the flat outsourcing wooden material is used as the external material, the surface of the wooden material is compounded with impregnated melamine urea-formaldehyde resin glue or solid wood veneer is hot-pressed, and then installed on the metal frame panel after cutting (solid wood veneer material cutting UV curing will be carried out later, and then assembled with the metal frame), and the edges will be sealed with metal buckles. That is to say, it has a certain fireproof function and has a solid wood texture and aesthetic effect.

Abstract

The invention relates to the technical field of wood doors and metal (plastic) doors outside which wooden materials are wrapped, in particular to a combined process for manufacturing a door, which is characterized by comprising the following process steps: a, a door frame manufacturing process; b, a surface board or door core manufacturing process; c, an edge strip manufacturing process; and d, a door assembling process. Compared with the prior art, the invention has the key of changing the production process of a surface material, firstly, the surface material and an economically suitable lining material (thickness is determined by design) are compounded (hot pressing) in advance, and then cutting and machining (plain end, rabbet, V-shaped and other plug connection forms) are carried out to obtain designed width or length dimensions and painting is carried out. The whole production process has high degree of mechanization, high production efficiency, esthetic exterior appearance, little manual work and reduction of dependence on people. The production factory area is reduced and the consumption of oil paint (process waste part) is reduced. The concave and convex phenomena of finished product appearances of the existing wood doors can be avoided.

Description

technical field [0001] The invention relates to the technical field of wooden doors and metal (plastic) doors covered with wooden materials, in particular to a combination process for making doors. Background technique [0002] The current paint door is divided into structural door and flat door according to the appearance structure. After being made into a whole door, it is painted and then installed at the place of use. There is a large error in the flatness of the door, which makes it impossible to paint with high efficiency. It needs to enter the painting process for multiple times of painting and polishing, which requires a lot of manual use and large fluctuations in quality. And there are internal structure processing defects that are exposed through the refraction of light after being painted. Overall perfection cannot be achieved. U.S. Patent No. 5,543,234 discloses a molded door with decorative molded recesses. WO0181055 discloses a molded door extended outwards b...
