Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pouring conveying, in particular to an automatic pouring conveying device for metallurgical standard sample production. BACKGROUND

[0002] The automatic pouring conveying device for metallurgical standard sample production is an automatic device that realizes the integration of metal melt pouring, mold conveying and casting transfer. Its core function is to carry multiple pouring molds through a conveying system, sequentially complete mold positioning, pouring, cooling and casting taking out, etc. to meet the needs of continuous production of metallurgical standard samples. The device needs to consider the adaptability of high temperature environment, the stability of heavy load mold and the precision of multi-station cooperation, which is the key equipment to improve the production efficiency and consistency of standard samples.

[0003] In the field of metallurgical standard sample production, the pouring mold usually adopts a semi-open structure with an open top for forming cylindrical metal ingots. Due to the differences in specification requirements of different standard samples, molds with different inner diameters of the mold cavity need to be used in the same batch production, resulting in significant differences in the solidification time of the metal melt after pouring.

[0004] The existing traditional conveying device mostly adopts a linear conveyor belt structure, and the mold needs to pass through independent stations such as pouring, cooling and taking out in sequence. This layout results in large equipment footprint and low production efficiency; more seriously, the open structure of the linear conveyor belt directly exposes the high-temperature mold, causing the workshop temperature to rise and deteriorating the operating environment. Some improved devices use a rotary conveying method, which realizes mold circulation conveying through a gear-driven turntable; but the traditional gear transmission system is limited by the fixed speed ratio, and the turntable rotates at a constant angular velocity. When producing different specifications of standard samples, small-size molds only need 60 seconds of solidification time, while large-size molds need more than 120 seconds. The rigid beat of the gear transmission forces all molds to stay for the longest solidification time, resulting in 60 seconds / time of invalid waiting for small molds and insufficient equipment utilization. More seriously, sudden stop adjustment of the beat will cause gear meshing impact, accelerate the wear of the transmission system and reduce the service life.
