Inner-barrel single mould pressing technology

Abstract

The invention discloses an inner-barrel single mould pressing technology. The inner-barrel single mould pressing technology comprises the steps of: firstly, chamfering the place where a blank is contacted with a convex mould; when processing in batches, firstly fixing the convex mould; then hanging the blank to a planned position of a lower workbench; starting up a pressing machine; guiding a guiding oblique angle of the convex mould into the blank under the driving of an upper workbench; aligning the centers of the blank and the convex mould; when the upper workbench is moved to a set position, finishing the molding of a work-piece; when pressing a single piece, directly placing the blank on the lower workbench; directly hanging the convex mould on the blank by a lifting crane; when the guiding oblique angle at the bottom of the convex mould enters into the blank, correcting the centers of the convex mould and the blank naturally and enabling the convex mould to be vertical to the surface of the lower workbench; and starting up the pressing machine for pressing. The inner-barrel single mould pressing technology, disclosed by the invention, has the advantages of saving cost, being simple in technology, solving the problem of easy de-molding as the work-piece is adsorbed on the surface of the mould, improving work efficiency and shortening production period of the mould.

Description

Technical field: [0001] The invention discloses a pressing process, in particular to a single-mode pressing process for an inner cylinder body. Background technique: [0002] At present, the forming dies in the machinery industry use the die to extrude the material, and use the plastic deformation characteristics of the material to realize the change of shape and size. Generally, the convex and concave dies are used in pairs. The punch is fixed on the upper movable slider of the press with bolts through the connecting handle, the die is initially centered by the concentric circles on the lower worktable of the press, and then a block of equal thickness is placed in the die, and the punch is lowered. Constantly correct the gap between the concave and convex dies to make them uniform. After the preparatory work is completed, move out of the lower workbench, hoist the workpiece blank into the die, and move into the lower workbench for pressing. Due to the tolerance range of...

AI Technical Summary

Problems solved by technology

[0005]Compared with the prior art, the present invention has the following characteristics: the cost of steel castings is saved, and both the concave and convex dies are processed into only the convex dies, It solves the problem that the workpiece is adsorbed on the surface of the mold and is not easy to demould, improves work efficiency and shortens the production cycle of the mold
