Horizontal stator buckle slab withholding equipment and method

Abstract

The invention discloses horizontal stator buckle slab withholding equipment and a horizontal stator buckle slab withholding method. The withholding equipment comprises a hydraulic machine body, and buckle slab pressing heads, a mobile bracket, an oil cylinder and a pressure head connecting plate arranged on the hydraulic machine body, wherein the pressure head connecting plate is arranged on the hydraulic head of the oil cylinder. The withholding equipment is characterized in that: the mobile bracket is arranged in the centre of the hydraulic machine body; the two buckle slab pressing heads are respectively arranged at the two ends of the hydraulic machine body, wherein one buckle slab pressing head is fixed on the pressure head connecting plate while the other buckle slab pressing head is fixed on the hydraulic machine body; and the lower end of the mobile bracket is provided with a bracket moving roller. Compared with the prior art, two buckle slab pressing heads are respectively arranged at the two ends of the mobile bracket of the hydraulic machine body in the withholding equipment, so that the two sides of a stator component on the mobile bracket are withheld at the same time. Therefore, buckle slab acting forces on the two symmetric sides are the same; the withholding quality of the buckle slab is good; a process is simple; and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of motor manufacturing, and is suitable for a crimping process of thicker stator buckles of buckle-type low-voltage high-power motors and double-fed wind power generators. Background technique [0002] At present, the stator of domestic buckle-type low-voltage high-power motors and double-fed wind turbines, the outer circle of the stator is between 700 and 1180mm, the thickness of the buckle is generally 3-5mm, the width is 30-50mm, and the number of buckles is generally 12 or 16 Equally divided, the buckle is folded into a 105-120°V shape, and the buckle pressure required for the buckle (flattening) is relatively large. Generally, a vertical single-head hydraulic rolling machine is used for single rolling, or a vertical rolling machine is used. The hydraulic press of more than 200 tons lays the stator core horizontally and then presses it horizontally. The process is complicated, difficult and the production efficien...

Generally, a vertical single-head hydraulic rolling machine is used for single rolling, or a vertical rolling machine is used. The hydraulic press of more than 200 tons lays the stator core horizontally and then presses it horizontally. The process is complicated, difficult and the production efficiency is low.
