Description

Technical Field

[0001] The utility model relates to the field of automatic marking and cutting of plates, in particular to a cutting and marking system for heat exchanger plates. Background Art

[0002] Plate-fin heat exchangers are special equipment pressure vessels. The traceability of raw materials must be guaranteed throughout the production process. The pressure vessel standard clearly requires that material marking and transplantation must be done before material segmentation. The marking content includes: drawing number, raw material batch number, and production serial number. The current practice is to cut with a manual circular saw. Before cutting each plate, the marking content is written manually with a marker pen, and the marking content is engraved on the surface of the raw material with an engraving pen to form a permanent mark. However, manual cutting and material marking are cumbersome, inefficient and prone to errors. If machine cutting is used, the problem of automatic cutting can be solved, but there are still the following difficulties: First, machine automatic cutting uses nesting software to automatically arrange the pattern, and then automatically cuts according to the pattern. Before cutting, the raw material is a whole plate, and it is impossible to manually determine the location of each part, so manual material marking is impossible; second, the heat exchanger is a non-standard equipment, and the parts cut from each raw material plate will have a variety of different shapes and sizes. According to the requirements, the material marking needs to be at a fixed distance from the edge of the part, which requires the marking action to be linked with the shape and size of the part; third, the normal automatic cutting methods are: plasma cutting, laser cutting and water jet cutting, among which water jet cutting itself cannot perform marking work; and laser and plasma are both thermal processing processes, which will melt the attachments on the surface of the raw material. Due to its special use, the heat exchanger product has very high requirements for surface cleanliness. There must be no slag and organic matter on the surface of the entire raw material, so laser and plasma cannot be used for marking. Utility Model Content
