The automatic flipping device for integral core trimming of side frame of railway wagon

Abstract

The invention relates to a truncated type automatic turnover device used for a railway freight car side frame casting mold integral core, which has the advantages that the structural design is simple, installation and dismounting are convenient and rapid, and clamping is reliable; a claw has pneumatic synchronous operation performance, can realize accurate positioning, has floating clamping function and can compensate various positioning errors, the strength of clamping force can be smoothly adjusted by a pneumatic device, rapid and stable movement can be carried out while grabbing the casting mold integral core, and no damage is generated on the integral core. automatic overturn function can be realized through a mode that cylinder inflation of a pinion and rack overturn cylinder mechanism drives an overturn supporting plate (and the casting mold integral core) to automatically overturn with an angle of 90 DEG. The usage process of the automatic turnover device is safe and reliable, the automatic turnover device can be worked under severe environment such as high temperature, vibration and corrosion, production efficiency and working efficiency are increased, and the automatic turnover device can satisfy the characteristics of working condition requirements of side frame production.

Description

technical field [0001] The invention relates to an automatic overturning device for integral core trimming of railway freight car side frame casting molds, in particular to an automatic overturning device for railway freight car side frame casting mold integral core trimming in the foundry industry. Background technique [0002] In order to meet the needs of heavy-load speed-up and rapid development of railway freight transportation, the side frame used in the railway freight car is casted by the integral core process in the manufacturing process, specifically: the inner cavity of the side frame is designed as an upper and a lower piece. The sand core is poured through the sand mixer to complete the sand filling of the casting sand core, and then the upper core is turned over, and combined with the lower core to form a side frame integral core core (hereinafter referred to as the integral core). The overall core process can realize the integral sand core of the side frame ca...

AI Technical Summary

Problems solved by technology

However, in the manual core setting process of the integral core currently used, there is a problem that the integral core of the casting mold lies flat on the casting mold pallet, so that the side facing upwards can perform trimming work, and the side facing downwards cannot perform trimming work. The problem

It is easy to cause defects such as flashes, burrs, fleshy, steps, and rough casting surface after the side of the casting is poured and formed, so it is easy to bring potential safety hazards to railway freight transportation.
