With the rapid development of China's industrial system, more and more companies choose to add a planing process before bending sheet metal. The effect of the gouging process on the bending structure is small, but the R angle of the bending can be reduced, so that when the metal plates are spliced, the splicing edge fit and visual sense are higher. As the market competition becomes more and more important, and the customers have higher and higher requirements for product aesthetics, the planing process has become more and more popular among industrial companies. The following is to explain the industry market situation and parameter analysis of planer.
Brief introduction of domestic market planer industry:
In recent years, due to the increased appearance requirements of products and the rapid development of the planing machine industry, various large enterprises and various industrial chain accessories companies have purchased planing machined products;
Moreover, the planing groove technology is relatively mature in China, and the planing groove technology has become more popular in light and heavy industries.
Due to mature domestic technology, most domestic companies choose domestic brands when purchasing planing machines, and very few companies purchase imported brands from South Korea or Germany.
The most well-known companies in the domestic planing machine industry are Shanghai Hengli Forging Machine Tool Co., Ltd., established in 1993, Shanghai Hengli is the earliest professional manufacturer of metal plate planing machine in China;
It also introduced advanced technology from Japan and obtained a number of national patents. Its experience and strength are at the forefront of the country, and its technology and manufacturing are no less than imported products.
Other domestic brands also use Hengli as the industry benchmark, and their planer machines have a high market share in the country.
Parameter analysis of planing machine:
The basic principle of the metal plate planing groove process is to fix the metal plate and use the mechanical movement of the planer blade to cut off the material at the position on the movement track;
The process V groove is formed, and the size of the bending angle is related to the depth of the V groove. The smaller the bending angle, the larger the value of the depth of the V groove to be planed.
There are several technical parameters that have a greater impact on the planing process. The following uses the planing parameters of a planing machine as an example.
最大 Maximum width and length of slotted sheet: This parameter affects the maximum size that the equipment can process metal sheet.
最大 Maximum thickness of slotted sheet: This parameter affects the maximum thickness of the sheet metal that the equipment can process.
(3) The minimum distance between the V-shaped groove and the edge: This parameter reflects the minimum distance between the edge of the planing groove and the edge of the plate material when processing metal plates;
This distance is mainly the distance for the planer to grip the planer, plus the safety distance set by the manufacturer;
The smaller the value of the minimum distance between the V-shaped groove and the edge, the smaller the value of the minimum distance between the edge of the plate planer and the edge of the plate material.
⑷Cutting speed: This parameter reflects the speed of the tool's linear movement when processing metal plates. The larger the value, the higher the equipment processing efficiency.
分辨率 The resolution of the left and right and up and down movement of the tool post and positioning accuracy: each parameter mainly reflects the processing accuracy of the equipment. At present, the minimum positioning accuracy that can be achieved by domestic technology is ± 0.01mm.
In addition to the above-mentioned equipment parameters affecting the gouging process, another important parameter is the tool. The quality and number of tools directly affect the machining efficiency and the speed of tool wear.
The traditional planing equipment uses three blades for simultaneous cutting, and the current technology has become four blades for simultaneous cutting. The structure of the tools is shown in Figure 3. Each blade has a distance of 0.1mm. The maximum depth of the secondary gouge can reach 0.6mm.
In order to ensure the quality of the planing groove and prolong the life of the tool, the depth of a single planing groove set by a general enterprise is 0.4 to 0.5 mm.
The latest tools developed in the industry are alloy knives, and the service life of each stainless steel material is 2500 ~ 3000m.
