Intelligent ring sand box conveyor line

Abstract

The invention discloses an intelligent annular sand box conveying line which comprises an annular sand box automatic circulating line, wherein a plurality of box carrying trolleys which can move along the conveying line, are used for the placement of sand boxes and connected in an end to end manner, and a box pushing system for driving the box carrying trolleys are arranged on the sand box automatic circulating line; sand boxes are placed on the box carrying trolleys; the intelligent annular sand box further comprises a control system; the box pushing system comprises a box pushing motor controlled by the control system; the box pushing motor is connected with a frequency converter; the control system controls the start and the stop of box pushing as well as the rotating speed, so that the conveying of the sand box automatic circulating line is more intelligent.

Description

technical field [0001] The invention relates to the field of casting, more specifically, it relates to an intelligent annular flask conveying line. Background technique [0002] Lost foam casting (also known as negative pressure dry sand solid mold casting) is a solid mold casting in which foam plastic molds use binder-free sand combined with vacuum technology. After being coated with refractory paint and dried, it is buried in dry quartz sand for vibration molding, poured under negative pressure to vaporize the model, liquid metal occupies the position of the model, and solidifies and cools to form a new casting method. [0003] In the existing lost foam casting line, a closed circular conveying line is set up, and sand molding stations, pouring stations, sanding stations, etc. are arranged sequentially on the circular conveying line, and the sandboxes are arranged at intervals in the circular production. , through the driving mechanism to drive the sand box to move interm...

AI Technical Summary

Problems solved by technology

[0003] In the existing lost foam casting line, a closed circular conveying line is set up, and sand molding stations, pouring stations, sanding stations, etc. are arranged sequentially on the circular conveying line, and the sandboxes are arranged at intervals in the circular production. , through the driving mechanism to drive the sand box to move intermittently on the conveying line, so that the sand box passes through each station in turn, and finally completes the casting. The pushing box device in the prior art is basically set in advance. If the speed is adjusted again, it needs to be shut down. reset, not smart enough
