Abstract

The embodiment of the invention provides a hot stamping measurement tool and a use method thereof. The hot stamping measurement tool is refitted based on an ordinary single pull machine and mainly comprises devices of a water cooling substrate, an insert made of a mould material, a clamp for clamping the insert, a batten for testing, a plate material movement driving device, a device for heating aplate material, a thermoelectric couple for monitoring a temperature, a data collector, a computer for data observation and the like. According to the hot stamping measurement tool disclosed by the embodiment of the invention, the heating device, the testing device and the driving device are arranged on the same platform; varieties of parameters of a contact heat transfer coefficient between a hot stamping plate material and a mould, convective heat transfer coefficient of a runner, friction abrasion of the module and the like can be measured; the hot stamping measurement tool has the advantages of high automation degree, strong operability and rich functions; the parameters obtained from the testes can provide accurate input for hot press simulation analysis and has important significance in prolonging service life of the hot stamping mould and improving product performance.

Description

technical field [0001] The invention relates to the field of thermoforming such as hot stamping, in particular to a novel multifunctional tooling and a measurement method for measuring parameters such as contact heat conduction coefficient and convective heat transfer coefficient. Background technique [0002] With the continuous improvement of the automobile industry's requirements for safety performance and product lightweight, high-strength steel is more and more widely used in various parts of automobiles. At present, hot stamping can effectively solve the technical bottlenecks of easy cracking and difficult size control in the forming process of high-strength steel, and can minimize the thickness of the car body under the premise of ensuring strength and crash performance. It is a key technology in the process of automobile lightweight. [0003] Hot stamping technology involves temperature field-stress field coupling and fluid-solid coupling, and the material properties...
