How to improve wood utilization during wood door manufacturing

Due to the lack of timber resources and the rising price of wood, the way of using wood extensively in the past has not been able to adapt to the current market situation. Improving the utilization rate of wood is the foundation for the survival of wooden doors. In the manufacturing process of wooden doors, improving the utilization rate of wood is a comprehensive problem, involving many process links and processing processes in the manufacturing process of wooden doors. The following are small series from product design, wood material classification, wood material splicing, component processing, etc. Some methods of induction.

(1) Seriously carry out the standardization of parts and sizes, so that the size specifications of the parts are connected with the size specifications of the sawing materials, so as to make full use of the sheet size and saw more pieces of wool.

(2) Operators should be familiar with the technical requirements of various product parts and components. Under the premise of ensuring product quality and requirements, all the defects allowed by the material requirements, such as lack of shuttle, knot, crack, twill, etc., should not be excessively eliminated. Should be used as reasonably as possible.

(3) The operator should concentrate and mix the wool of various specifications according to the quality and specifications of the plate, and reasonably match and cut the saw; the unused scraps can be centrally managed for use in the configuration of small wool, so that the materials can be fully utilized.

(4) Under the conditions that do not affect the strength, appearance and quality, the defects such as dead knots, resin capsules, cracks, and insect eyes on the material surface can be repaired by means of excavation and inlaying to prevent the whole material from being cut off.

(5) For some short parts, such as wool, handles, etc., in order to facilitate post-processing and operation, the wool material should be firstly distributed, and after being processed into a solid material, it can be cut off or sawn to improve productivity and processing quality, and reduce Machining allowance for each wool.

(6) Reasonably determine the process route and reduce the repetitive machining allowance. In addition to the parts such as rubber and end opening, it is necessary to make a fine cut in the batching, and no secondary machining allowance is left.

(7) Under the design requirements, try to use the short corner material or the processing surplus and the small specification material to make the small parts wool material, so as to upgrade the small materials. According to practical experience, about 10% of wood can be saved.

(8) The thin saw blade and the small-diameter saw blade should be actively selected. The planing saw blade or the “saw-and-saw planing” process should be used as much as possible to reduce the loss of the sawing road. The one-time sawing can save the wood in 30%~50%.

(9) The method of cutting the line and cutting the ingredients after roughing should be used as much as possible. The production time proves that the wood utilization rate can be increased by 9%~12% (if the cross-line effect is better).

(10) For parts with larger specifications and sizes, according to the technical requirements, it is possible to replace the whole piece of wood with a small material length, a narrow material width, a thin material thickness and a small material glue, for the dark frame material and core. Strips, bending materials, long materials, wide materials, large broken fabrics, etc., can improve the utilization rate of wood, make use of inferior materials, use large materials, and ensure product quality, improve strength, reduce deformation and ensure shape The size is stable.
