Abstract

The invention relates to the woodworking industry, in particular to the production technology of frame doors of furniture. The purpose of the invention is to reduce the consumption of materials and labor input for the manufacture of frame doors of furniture. Frame doors of furniture include facing layers 1, between which face 2 and middle layers are placed, made from pre-fabricated wood boards. A template 6 is placed between the blanks to form the openings 4 of the package 5, which ensures the formation of the opening 4 and the formation of a fold. Pressing is carried out at 120 - 140 ° C and specific pressure of 8 - 12 kg / cm ² . The dwell time of the door after pressing is 4-6 hours. 7 Il.

The invention relates to the woodworking industry, in particular to the production technology of frame doors of furniture.

The purpose of the invention is to reduce the consumption of materials and labor input for the manufacture of frame doors of furniture.

FIG. 1 shows the layout of the bottom layers of the package and the template; in fig. 2 - the same, and the middle layer; in fig. 3 - the same, and the top layer; in fig. 4 - the same, without a template; in fig. 5 is a diagram of a frame door; in fig. 6 shows the layout of the layers; in fig. 7 is an opening arrangement diagram.

Frame doors of furniture include facing layers 1, between which face 2 and middle 3 layers are placed, made from pre-fabricated wood boards. A template b is placed between the blanks to form the openings 4 of the package 5.

Example 1. On a circular sawing machine, a wood-fiber board (MDF) is cut into strips 65 mm wide, 8 pieces thick in accordance with TU GOST 4598-86 and 4 pieces 8 mm thick.

A frame package with a size of 875x475 mm is drawn in: facing layers 1.4 of a 4-mm fiberboard strip with adhesive applied from two sides, pattern 6 is installed in the opening; 4 strips of fiberboard 8 mm and 4 strips 4 mm thick with adhesive applied. The template 6 is then removed and the facing layer 1 is laid. The first layer of 4 mm thick fiber strips is laid offset to form a fold. Then the packaged bag is loaded into the press. Pressing is carried out at 120-140 ° C and specific pressure of 8-12 kg / cm for 4-6 minutes. At a specific pressure of 8 kg / cm, individual strips are pressed and the overall thickness of the bag is leveled; with a specific pressure of more than 12 kg / cm, a pressing is carried out on the thickness of the entire package. Pressing time 4 min - when lined with synthetic veneer or textured paper; 6 min - when veneering with planed veneer.

At the end of the extrusion, the frame bag is unloaded from the press and held for 4-6 hours.

After the exposure time

Removing the overhangs of the facing layers 1 from the opening 4, fillet the frame door in length and width with the removal of the overhangs and lining the outer edges. Then the frame door is polished with a sandpaper (only in the case of veneering with planed veneer). Example 2. A frame door is made analogously to example 1, but a set of frame package is produced without displacement.

5 of the first layer of fiberboard 4 mm thick.

Example 3. A frame door is made analogously to example 1 and 2, but the middle layer is completed with 8 mm wrought iron chipboard (DSP) instead of 8 mm fiberboard.

0 Using the proposed method of making frame doors provides the elimination of the operations of cutting out an opening from a panel for a panel or glass, manually cutting out the four corners of the opening, placing a decorative bar on nails and glue; saving of raw materials due to more rational use of the plate (the output increases by a strip due to the absence of waste in the form of cutting out of the opening, in the manufacture of

0 doors; the possibility of obtaining frame doors with different design of openings.

Claims (1)
