Method for automatically transferring semisolid metal blank

Abstract

The invention provides a method for automatically transferring a semisolid metal blank. The method comprises the following steps of: setting a process parameter through a hydraulic automatic control device; making a clamp of a mechanical clamping device in an open state at an initial position; detecting the position of the blank by a measuring and positioning device, and adjusting the position of the mechanical clamping device; measuring the temperature of the blank by a temperature measurement device, and feeding back the temperature to the hydraulic automatic control device; performing data analysis on the measured temperature by the hydraulic automatic control device, and sending an instruction; and making the clamp closed when the mechanical clamping device receives the instruction of the hydraulic automatic control device, clamping the semisolid metal blank and putting into a semisolid metal molding die, and returning to the initial position. According to the method, semisolid metal heating and molding devices are butted together, so that the semisolid metal blank can be transferred automatically.

Description

technical field [0001] The invention relates to the technical field of nonferrous metal processing, in particular to a method and device for automatic transfer of semi-solid metal blanks. Background technique [0002] At present, in the field of metal processing, more and more processes use automatic loading and unloading devices to transfer heated metals, such as die-casting and forging. Usually, the liquid metal is quantitatively transported by the melting crucible through the pipeline, and the solid metal is transported by the high-temperature automatic device, but for the automatic transfer process of the semi-solid metal billet, the above two methods cannot be normally realized. Because semi-solid metal blanks have unique material properties. The semi-solid metal billet is in a solid-liquid two-phase mixed state, and its viscosity is dozens or even hundreds of times higher than that of liquid metal. The pipeline transportation of liquid metal cannot realize its normal ...

AI Technical Summary

Problems solved by technology

The semi-solid metal billet is in a solid-liquid two-phase mixed state, and its viscosity is dozens or even hundreds of times higher than that of liquid metal. The pipeline transportation of liquid metal cannot realize its normal transfer due to too much flow resistance; the semi-solid metal billet is heated. , has a certain strength, but compared with solid metal, the strength of the material is much lower, while the mechanical force of the conventional solid-state forming transfer device is relatively large, and the control accuracy is not high

The strength of the semi-solid metal blank has a great relationship with the temperature of the blank. Therefore, if a solid-state forming automatic transfer device with a fixed clamping force is used, it is easy to damage the shape of the semi-solid metal blank, resulting in defects such as cracks and interlayers during the forming process. lead to product performance degradation

Over the years, the research and development of semi-solid metal heating and forming devices has been popular, but the transfer of semi-solid metal billets has been less developed, and the traditional automatic transfer device cannot meet the transfer needs of semi-solid metal billets, so it is hoped to develop a The automatic transfer device suitable for semi-solid metal blanks not only meets the needs of automatic transfer of blanks, but also requires the minimum damage to semi-solid metal blanks, and has the characteristics of easy control and maintenance
