Automatic forming machine for rotor coil of wind generating set

Abstract

The invention relates to an automatic forming machine for a rotor coil of a wind generating set. The machine comprises a master control hydraulic station and a pair of oppositely-arranged performing mechanisms, wherein each performing mechanism comprises a base, a frame, a fixed mold, a master arm, a movable mold and an active forming oil cylinder; the frame is fixed on the front part of the base; the fixed mold is fixed on the back part of the base; the master arm is pivoted with the fixed mold through a rotating shaft; the movable mold is arranged on the master arm; the forming surfaces of the movable mold and the fixed mold are opposite to each other and are matched with the shapes of the upper and lower curved surfaces of the rotor coil of the wind generating set respectively; one endof the active forming oil cylinder is pivoted with the frame, while the other end is connected with the movable mold; and the active forming oil cylinder is in transmission connection with the mastercontrol hydraulic station. The machine has the advantages of high forming accuracy, high processing efficiency, wide application range, safety, reliability, convenient maintenance and the like.

Description

technical field [0001] The invention relates to a motor coil forming machine, in particular to an automatic rotor coil forming machine for a wind power generating set. Background technique [0002] At present, the country is gradually increasing the investment and development of western energy. Wind power generation, relying on renewable and sustainable clean energy, has become the new energy industry with the most large-scale commercial development in recent years. However, as the core part of wind turbine manufacturing—rotor coil forming technology is always the key to restricting the performance of the motor and improving production efficiency. [0003] The wind power rotor coil is composed of multiple groups of coils, and each group is fitted by two copper bars with rectangular cross-sections side by side according to the spatial multi-dimensional curve. The spatial rotation angle and spacing have strict requirements, and the forming is extremely difficult. Except for a...

Problems solved by technology

Except for a few companies in the motor industry that have imported high-end forming equipment from abroad, most companies can only rely on self-made special molds and manual knocking to form. The coils completed by different operators cannot be used in the same group due to different strengths and difficult fitting of shapes. When the coil specifications increase, the consumption of personnel, tooling and site occupancy will increase exponentially. Quality and productivity are also difficult to guarantee
