Model bottom plate and sand box transfer device

Abstract

A model bottom plate and sand box transfer device comprises a frame, a pair of chain wheels is coaxially mounted at two ends of the frame respectively, a towing chain is assembled on the two front and back chain wheels, a towing chain driving mechanism is arranged on the frame, bearing rails composed of two parallel steel rails are arranged on two sides of the upper portion of the frame respectively, each bearing rail is provided with a model bottom plate and sand box trailing device respectively, and the model bottom plate and sand box trailing devices are provided with groove-steel bearing guide beams respectively. Bearing rollers with flanges in the roller surface middle portions are distributed on the bearing guide beams, the roller surfaces on two sides of the flanges are matched with steel rail surfaces of the corresponding bearing rails respectively, and two ends of the bearing guide beams are connected with the corresponding towing chains via chain joints. The model bottom plate and sand box transfer device is used for casting modeling lines and can ensure normal transfer of model bottom plates and sand boxes at the T-shaped and crisscrossed positions. In addition, manufacturing cost of equipment can be greatly reduced, and operation reliability of equipment is improved.

Description

Technical field [0001] The invention relates to casting production equipment, in particular to a model bottom plate and a sand box transfer device used in cooperation with a motorized roller table. Background technique [0002] At present, the casting industry's modeling and core-making lines generally use transfer rollers to transfer the model bottom plate and the sand box at the T-shaped and cross-shaped cross positions. The transfer roller table provides transfer power through the sprocket chain drive mechanism, and relies on two rows of side rollers to carry and transfer the model bottom plate and the sand box. The number of side rollers required is large, and the operation accuracy requirements for the two rows of side rollers are also relatively high. The manufacturing cost and failure rate of the transfer roller are higher. Summary of the invention [0003] The purpose of the present invention is to solve the above problems and provide a model bottom plate and a sand box t...
