Model bottom plate and sand box transfer device

Abstract

A model bottom plate and sand box transfer device, including a frame, a pair of sprockets are coaxially installed at both ends of the frame, a drag chain is assembled on the two corresponding front and rear sprockets, and a The drag chain drive mechanism is equipped with load-bearing rails composed of two parallel steel rails on both sides of the upper part of the frame. A model bottom plate and sand box hauling device are respectively installed on each load-bearing track. The model bottom plate and sand box haul The device has a channel-shaped load-bearing guide beam, on which there are load-bearing rollers with flanges in the middle of the roller surface, and the roller surfaces on both sides of the flange are respectively matched with the rail surface of the corresponding load-bearing track. Both ends of the guide beam are respectively connected with corresponding drag chains through chain joints. The invention is used in a casting molding line, can ensure the normal transfer of the model bottom plate and the sand box at the T-shaped and cross-shaped intersection positions, can greatly reduce the manufacturing cost of the equipment, and improve the working reliability of the equipment.

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 molding and core-making lines in the foundry industry generally use transfer roller tables to transfer the model bottom plates and sand boxes at the T-shaped and cross-shaped intersection positions. The transfer roller table provides the driving force 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 required number of side rollers is relatively large, and the requirements for the running accuracy of the two rows of side rollers are also relatively high. The manufacturing cost and failure rate of the transfer roller table are higher. Contents of the invention [0003] The object of the present invention is to solve the above problems ...
