Manufacturing technology for curved face base plate of seat chair

Abstract

The invention discloses a manufacturing technology for a curved face base plate of a seat chair. The manufacturing technology includes the following steps that (1) sandwich plate pretreatment, specially, sanding treatment and hot pressure treatment are conducted plate materials which serve as sandwich plates in sequence, and the sandwich plates with the flat surface are obtained; (2) panel treatment, specially, the hot pressure treatment is conducted on plate materials which serve as panels; (3) drying, the sandwich plates and the panels processed through the step (1) are placed on a kiln car, a space is reserved between the every two adjacent plates, and then the kiln car is sent to a drying kiln to be dried; (4) composite plate pressing, specially, the dried sandwich plates and the panels are adhered by using glue, and then the dried sandwich plates and the panels are pressed and composite sandwich composite plates; (5) the composite plates are pressed and formed, and curved face base plate semi-finished products which are designed into a curved face shape are obtained; (6) curved face base plate semi-finished product form imitation; and (7) painting, specially, curved face base plates which conduct the form imitation are coated with paint, and curved face base plate manufacturing is completed. By means of the manufacturing technology, the wood plates are dried fully, the suitable moisture content is kept, deformation and cracking of the plate materials are avoided, and the product quality is improved.

Description

technical field [0001] The invention relates to a manufacturing process of a backing plate, in particular to a manufacturing process of a curved backing plate of a seat. Background technique [0002] At present, the curved backing board of the seat all adopts a wooden board of a certain thickness to be made after being dried, heated and pressed into a curved shape, and then coated with a layer of paint. In the current manufacturing process, there are the following disadvantages: 1. Insufficient drying of the plank, easy to mildew and decay, paint peeling and peeling, easy to crack, and the quality of the finished product is poor. This is because in the current process, the wood boards are stacked on the kiln car and sent to the drying kiln for drying in the drying process of the wood boards. Due to a large number of wood boards stacked, the gaps between the boards are small, so that the water is not easy to evaporate, so that the wood boards cannot be fully dried. Dry, easy...

Problems solved by technology

In the current production process, there are the following disadvantages: 1. Insufficient drying of the wooden board, easy to mildew and decay, peeling off paint and peeling, easy to crack, and the quality of the finished product is poor

This is because in the current process, the wood boards are stacked on the kiln car and sent to the drying kiln for drying in the drying process of the wood boards. Due to a large number of wood boards stacked, the gaps between the boards are small, so that the water is not easy to evaporate, so that the wood boards cannot be fully dried. Dry, prone to mildew and decay, poor adhesion and paint adsorption, and the product is prone to paint peeling and peeling

Furthermore, if the drying is insufficient, the internal stress inside the board is not reduced to the greatest extent, which may easily cause the board to crack

2. After the wood board is dried, it is not processed immediately, the wood board absorbs air moisture, and needs secondary drying treatment, resulting in reduced production efficiency and increased costs

4. Curved backing plate has low strength and short service life
