Description

Lifting movable table for large plate nesting, method for generating processing table, large plate nesting Cutting method and storage medium

technical field

The invention relates to the technical field of large-board nesting equipment, in particular to a lift-type movable table for large-board nesting, a method for generating a processing table, a large-board nesting processing method and a storage medium.

Background technique

Different types of processing equipment are used in the panel furniture production industry. According to the processing process, they are mainly related equipment such as cutting, drilling, milling, and edge sealing. This patent relates to the equipment in the cutting process.

Traditional batch processing and production mostly use saw-type cutting equipment such as electronic saws. In recent years, machining center-type large-board cutting and cutting equipment has been widely used, especially in the custom furniture industry. The working method of the large plate nesting type machining center is to adsorb a large plate on the machine table as a whole, and then directly mill each small workpiece by the spindle tool. Workpieces with missing arc angles, etc.

It is very important to firmly adsorb the board on the table to ensure the processing accuracy and processing efficiency of the large-board set-cutting equipment. At present, the table top of almost all large-board cutting equipment adopts a grid-type table surface. Multiple vacuum ports are arranged under the table to connect the vacuum pump to generate the vacuum of the whole table. The table top is covered with medium and low density fiberboard as a backing plate. The vacuum airflow can reach the upper surface through the gap in the board, and the large board to be cut is placed on the surface of the pad for adsorption.

The schematic diagram of the existing table structure and the position of the backing plate is shown in Figure 1. During the production process of the large-board nesting equipment, the workpiece should be divided one by one to ensure the processing quality. Therefore, if the tool must ensure that the workpiece is thoroughly milled, the processing depth will exceed the raw material. The bottom surface of the plate, thus leaving a knife mark with a depth of 0.1 to 0.5 mm on the backing plate. After a period of production, the dense tool marks will reduce the adsorption force of the backing plate and increase the probability of running the plate. At this time, the surface of the backing plate needs to be milled flat, and the thinner the backing plate is to be replaced. Generally, the frequency of replacing the backing plate in the factory is about half a month to a month.

Due to the diverse characteristics of the size of the plate, in order to reduce unnecessary waste of resources, the vacuum port of the table is usually controlled by partition, that is, the control valve of each vacuum port is controlled separately. At present, the common practice is to divide the table into 4 to 6 areas to meet the processing needs of raw material slabs of different sizes. The common raw material slab sizes in China are 4*8 feet and 4*9 feet. When switching between different slab sizes, the use of the corresponding vacuum area is automatically controlled.

However, the existing mesa structures and the way they are controlled have the following disadvantages:

(1) There are various sizes of raw material slabs. In addition to the commonly used 4*8 feet and 4*9 feet, there are also commonly used 2.1m*2.8m and 2.1m*4m in foreign countries. Only a small amount can be dealt with through the large-scale partition of the countertop. size changes.

(2) There is a feeding link in the production process. In the process of processing, there will be a situation where the processing quality is poor or the processing error in the subsequent production process leads to a new piece of workpiece. At this time, the remaining sheets in the factory (larger than the size of the workpiece to be supplemented) are often used on the equipment to process the supplementary piece separately. workpiece. The plates used in feeding are basically production surplus materials, which have various sizes and no fixed specifications. When placed on the table, one or more vacuum areas cannot be completely covered. During processing, all the vacuum areas that will be used for the remaining material must be opened, but since it cannot completely cover all the opened vacuum areas, it will cause a certain area of vacuum leakage, and it is easy to run the board during feeding processing.

(3) The grid design of the table can make the vacuum flow through the whole table, but in practical applications, the adsorption force of the area near the vacuum port is still stronger than the adsorption force of the area far from the vacuum port, so the adsorption force of different areas of the table There is a difference in strength, especially the weakest suction at the edge of the table.
