Application and description of optimized cross-cut saw case

Solid wood veneer cutting material is one of the three major raw materials for furniture production. The preparation of component materials is a very important part of furniture manufacturing, which has a great influence on the production quality and post-processing of furniture.
There are two processes in the preparation of part wood. The preparation of commonly used furniture parts includes material selection and sawing.
Optimize the material selection process of cross-cut sawing: mainly carry out detailed material selection, matching and defect marking of raw materials;
sawing process: conduct reasonable vertical and horizontal cutting of selected raw materials according to the specifications and shapes of furniture parts, so as to achieve reasonable matching and make the best use of everything Use, high quality and high efficiency, also known as ingredient processing.
Material selection Generally speaking, the selection of solid wood sawing materials should follow the following principles:
1. Determine the type and grade of materials according to product design requirements.
2. Determine the material standard according to the position, force and function of the furniture parts in the product.
3. Determine the color selection standard or processing technology of sawn timber according to the color effect of the product.
4. Ensure that the moisture content of raw materials meets the technical requirements of the product.
5. The specifications of the selected raw materials should be related to the specifications of the processed parts as much as possible.

 

Cross-cut saw CNC has two major systems: multi-functional material selection and cutting system and automatic detection and feeding system, which can realize material selection and preparation, and is suitable for whole house customization, door and window enterprises, Chinese style and new Chinese style furniture material enterprises.

 

CNC cross-cut saw – multifunctional combined cutting system:

Bending straightening, length optimization, numerical optimization, fixed cutting, scanning processing.

 

CNC cross-cut saw – automatic detection feeding system:

Automatically detect material scars and material length, and automatically load materials according to the data.

When the feeding system is backed up, the lines drawn on the surface of the material and the length of the material are scanned, and the computer is controlled to synchronize the data and optimize.

 Raw material output control

There are many factors that affect the yield of raw materials: such as the size, shape and quality requirements of processed furniture pieces, wood processing methods and processing methods, specifications and grades of raw materials used, etc. , technical level, etc. Operators, optimized cross-cut saws and sawing tools used, etc.

In the process of production and processing management and actual operation, the following measures can be considered to improve the output rate of optimized cross-cut saw raw materials:

• Realize the standardization of part size, link the part size with the raw material size, make full use of the thickness accumulation of the plate, and reduce the remaining consumption in the thickness direction as much as possible.
• The length and width of furniture parts should match so that as many parts as possible can be matched on the same raw material format. If necessary, the raw material can be sorted according to length and width, which can even be optimized using automated equipment such as preferred saws.
• When batching, the operator must be familiar with the technical requirements of each product part. Under the premise of effectively guaranteeing product quality, try to use the allowable defects of wood, such as missing edges, knots, cracks, twill, etc., and cannot be excessively eliminated.
• For some products and parts, defects such as scabs, fat cysts, cracks, and wormholes on the wood surface can be repaired by repairing and repairing, without affecting the strength, appearance, and quality of use of the material. Inlaid, to avoid the waste of the entire material.
• Optimizing the cross-cutting saw adopts advanced automatic batching equipment or tools, such as ultra-thin saw blades or small-diameter saw blades, to reduce the loss of the sawing path, or adopt the “saw instead of planer” processing technology to reduce the processing allowance, thereby reducing the processing part Loss.
• Some small parts, such as decorative strips, connecting strips, handles, etc., can be made into a variety of raw materials during the batching process to facilitate the processing and operation of subsequent processes. It can be processed and shaped first, and then cut or sawed, which not only improves productivity, but also reduces the processing allowance of each raw material.

For large pieces of standard size, according to the technical requirements of the product, the optimized cross-cut saw can be spliced ​​with small wood instead of whole wood, and can also be made into packaging materials or hollow structures. This method not only ensures the strength and appearance quality requirements of the parts, but also reduces deformation and improves the utilization rate of wood.

Optimizing the preparation process of straight parts for cross-cut sawing

The common process route for wire material preparation is:
sawn timber→longitudinal section→(pre-planing)→cross-section (or priority)→planing (planing→press planing or four-sided planing).
Larger sections should also be spliced.

1. Longitudinal section of sawn timber

The equipment used for the optimization of lumber longitudinal and cross-cut saws mainly includes full circular saws (ordinary desktop circular saws), mechanical (or crawler) feed single or multi-blade saws, various band saws, etc.

The universal saw is the most common vertical section circular saw. Has a strong versatility. Suitable for simultaneous processing of longitudinal and transverse sections. However, the production and processing efficiency is low, and the labor intensity of the operators is high. Generally, it is only suitable for the preparation of small woodworking enterprises or manual batching of board raw materials.

The production efficiency and quality of the single vertical saw are higher than that of the universal saw. The operation is more convenient and the adaptability is stronger. It is suitable for the longitudinal section processing of most furniture parts, and is also commonly used for trimming of raw boards. But the disadvantage is that the loss of the sawing path is large, which affects the yield to a certain extent.

Multi-blade circular saws can be equipped with several saw blades at the same time. The optimized cross-cut saw can simultaneously cut several panels of different thicknesses. It has the advantages of fast feeding speed, high production efficiency, narrow sawing path and high yield. However, it takes time to adjust the machine, so it is mainly suitable for enterprises with large plate production volume.

2. Plate cross section

There are many types of horizontal sawing of solid wood panels, such as hanging saws, radial arm saws, sliding table saws, pneumatic high-speed cutting saws and automatic profile saws.
If the products ordered by the enterprise are complicated, there are many types, and there are many specifications of furniture accessories, it is difficult to process with ordinary profile saws. For example, the length matching of sheet metal leads to low yield. Therefore, optimized cross-cut saws are often used for length optimization in furniture production.

3. Automatic section saw

1. Marking 2. Defect detection 3. Computer typesetting 4. Positioning cutting 5. Scrap handling 6. Part sorting
Wool processing
After longitudinal sawing or cross-section sawing, the appearance size of the blank part is still different from the target specification. It needs further processing to obtain the desired overall size.
The raw material processing equipment for linear parts mainly includes planers, planers, double-sided planers, four-sided planers, vertical shafts, trimming saws, etc.
