Problems solved by technology

The non-inflatable mold with integral mold core cannot meet the roundness requirements, and the mold ejection process is easy to strain the mold; the traditional bulge mold is in the form of full cylindrical surface contact, and anti-deformation is also applied to the part of the stator that does not undergo welding deformation , while offsetting the welding deformation, it causes deformation to other parts, and excessive anti-deformation will also make the roundness not meet the requirements

Abstract

The invention discloses a stator iron core overlaying welding mold. A stator iron core comprises a stator upper pull ring, a stator lower pull ring, a stator punching piece and multiple stator pull plates; the stator punching piece is arranged between the stator upper pull ring and the stator lower pull ring; the multiple stator pull plates are uniformly distributed at the outer periphery of the stator punching piece; the welding mold comprises an upper pressing plate, a lower pressing plate, an inner mold and an outer mold; the inner mold and the outer mold are arranged between the upper pressing plate and the lower pressing plate; the outer mold comprises multiple fan-shaped blocks; the fan-shaped blocks are as many as the stator pull plates; the inner surfaces and the outer surfaces ofthe fan-shaped blocks are arcs; the multiple fan-shaped blocks are uniformly arranged at the outer periphery of the inner mold; limiting pieces are arranged at the outer peripheries of the multiple fan-shaped blocks; the outer surface of the inner mold is an inner mold conical surface; the inner surfaces of the fan-shaped blocks are outer mold conical surfaces matched with the inner mold conical surface; and the outer surfaces of the fan-shaped blocks are matched with the inner surface of the stator punching piece. The reversible deformation is only applied to welding deformation positions ofthe stator pull plates, so that the welding deformation is effectively counteracted, and the inner circle roundness of the stator iron core can be guaranteed.

Description

technical field [0001] The invention relates to a stator core welding process in motor equipment, in particular to a stator core lamination welding mold. Background technique [0002] The motor stator core lamination (welding) mold is a mold used for the lamination of the motor stator punching sheets. After the lamination of the punching sheets, it needs to be welded to make the stator a whole. For the organic shell stator, the laminated stator only needs to weld a few buckles symmetrically on the outer circle, and the influence of welding deformation is small. For the caseless stator, several pull plates (usually 4) need to be welded on the outer circle, and the pull rings at both ends, the stator punching piece and the pull plate are welded into a whole to form the stator core, but the welding deformation has a great influence. After lamination of the stator core without casing, four pull plates are welded roughly evenly on the outer circle, so that the stator forms a who...
