Problems solved by technology

These methods have been well applied in actual engineering, but there are still some shortcomings. The low-melting point alloy mold needs to be equipped with a special casting process, cast in a prefabricated cavity, and necessary processing is required to ensure that the mold Precision, complex process, not suitable for the development of new models; the pouring temperature of zinc-based alloy molds is generally above 400°C, which requires high casting technology and models, and is generally only used to make stamping dies; the production process of epoxy resin molds is relatively simple , but limited by the physical properties of the material itself, the strength and surface wear resistance of the mold are slightly worse
In view of the above problems, the CN03134500.X patent proposes a rapid manufacturing method for stamping dies of electric arc spraying automobile panels, which is a typical replica method. In order to realize the distribution of gradient functions, a variety of different backing materials are required, and the realization process is relatively complicated.

Abstract

The invention discloses a quick and high-precision method for manufacturing a layered modular automotive panel die based on a laser combination processing technology. In the method, the quick and high-precision manufacturing for the automotive panel die is realized by mainly using a laser cutting processing technology and secondarily using a laser surface strengthening and cladding technology in combination with a layered modular die structure design method, so a quick and economic technology supporting measure is provided for trial-manufacturing of sample automobiles and panel dies during novel automobile type development. The method comprises the following processes of layering and cutting the die, positioning and connecting a modular combination, strengthening and cladding the laser surface and the like so as to finally form the layered modular automotive panel die on a partial key part; the material is in a functional gradient distribution from outside to inside; and the various structural layers have different mechanical performance and functions, so the whole performance requirement of the die can be guaranteed, the process is simplified and the cost is reduced. By the method, samples can be provided for trial-manufacturing of 200 sample automobiles; at the same time, sufficiently reliable experimentally checked design data can be provided for steel dies for normal production.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing technology, and relates to a rapid mold manufacturing method, in particular to a rapid manufacturing method of an automobile panel mold using computer graphics, laser cutting, laser surface strengthening and laser surface cladding technologies. Background technique [0002] The so-called rapid mold manufacturing technology is relative to the current large-scale mass production of automobile panel molds. Its typical manufacturing process mainly includes: blank casting, wire cutting, EDM, CNC machining, heat treatment, etc. It requires a large-scale complete set of specialized process equipment that is compatible with the process. The cost of equipment is high, the investment is large, and the production organization and management are complicated. Rapid molds (or simple molds) generally have the characteristics of short manufacturing cycle and low cost, and are suitable for trial production of...
