Pneumatic flexible core assembling tool

Abstract

The invention relates to the field of casting technologies, in particular to a pneumatic flexible core assembling tool. The pneumatic flexible core assembling tool comprises four sets of pneumatic core assembling tables. The pneumatic core assembling tables are arranged in the X direction and the Y direction of a plane core assembling platform correspondingly, and every two sets of pneumatic core assembling tables are arranged oppositely. Each set of pneumatic core assembling table comprises a pneumatic cylinder, a clay core positioning block, guide rails and a regulating valve. A piston of each pneumatic cylinder is connected with the corresponding clay core positioning block through a connecting rod. Each clay core positioning block is installed on the corresponding guide rails. Each regulating valve communicates with the corresponding pneumatic cylinder. The guide rails are further provided with buffer type clay core positioning blocks. Each clay core positioning block is connected with the corresponding buffer type clay core positioning block. The pneumatic flexible core assembling tool has the beneficial effects that first, the phenomenon that castings with a high dimensional accuracy requirement cannot get stuck in place is reduced, and brittleness core assembly damage and scrapping are also reduced; and second, as for castings with a low dimensional accuracy requirement, the fit clearance of clay cores can be made relatively small, clay core movement can be reduced, and dimensional accuracy of inner cavities of the castings is improved.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a pneumatic flexible core assembly tool. Background technique [0002] Sand casting core wire has the advantages of high production efficiency, good casting dimensional accuracy and easy control of casting quality. As my country moves from a large foundry country to a powerful foundry country, core wire will be widely used in the field of foundry production. Core assembly is a key process in the core-making line. The existing core assembly table usually adopts hydraulic and high-pressure cylinders, and the core assembly is forced into place. However, when there are many core groups and the matching clearance of the core heads is small, it is easy to get stuck, causing the core to break and result in waste cores; when the matching clearance of the core heads is large, the mud core will move and affect the dimensional accuracy of the casting cavity.
