Embodiment Construction
[0017] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0018] During the cutting process of metal-resin laminated materials, a large amount of cutting heat will be generated, which will cause the temperature in the cutting area to rise rapidly. Due to the obvious gradient of material properties on both sides of the bonding interface of the two materials, a large amount of cutting heat generated by metal material cutting is transmitted through the interface. To the side of the resin material, the temperature of the composite material at the interface is raised. For example, during the processing of a laminated material composed of a resin-based composite material (Carbon Fiber Reinforced Plastic / Polymer, CFRP) and a metal, due t...

The embodiment of the invention provides a temperature control device for a cutting region of heterogeneous materials. The temperature control device comprises a cooling device, the cooling device isarranged on a machine tool and comprises a temperature measuring device, a cooling spray nozzle and a controller, and the temperature measuring device and the cooling spray nozzle are connected with the controller; the temperature measuring device is fixed to a cutting tool of the machine tool, the cooling spray nozzle is used for cooling the tool, the cutting region of workpieces and a machined region, and the controller is used for receiving real-time temperature measured by the temperature measuring device and controlling the cooling spray nozzle to cool the tool, the cutting region of theworkpieces and the machined region when the real-time temperature is higher than a set temperature threshold value. The problems are solved that in the prior art, a temperature control system and method for the cutting region are only used for a single kind of materials, do not consider influences on machining performance of a temperature gradient of a machining region when several kinds of materials are machined together, and are difficult to apply to machining the heterogeneous materials.
Description
technical field [0001] The invention relates to the technical field of mechanical processing control, and more specifically, to a temperature control device for a cutting region of heterogeneous materials. Background technique [0002] Based on the forming theory and method of modern material compounding, two or more heterogeneous materials are compounded to obtain high-performance materials with the advantages of each single material, such as co-cured materials and laminated materials. On the other hand, in order to improve the connection performance of mechanical structures, in the field of modern mechanical processing, there is often a demand for simultaneous processing and one-time molding of mechanical connection structures of heterogeneous materials, such as a large number of metal and resin-based composite laminated mechanical connection structures in the aerospace field. Wait. [0003] Due to the differences between material properties, processing heterogeneous mate...
