The invention discloses a manufacturing die and method for a variable-cross-section iron core. The manufacturing die for the variable-cross-section iron core comprises a lower die holder base plate. A lower die holder is arranged on one side of the upper portion of the lower die holder base plate. Linear guide rails are arranged on the lower die holder along the axis in a bilateral symmetry mode. A female die fixing plate is arranged above the lower die holder and fixed to the linear guide rails. A motor initial positioning block is arranged on the axis of the lower die holder. A male die, a discharging plate seat and a male die fixing plate are arranged above the female die fixing plate, and the male die, the discharging plate seat and the male die fixing plate are fixedly connected. A motor supporting plate is arranged on the other side of the upper portion of the lower die holder base plate. A high-precision positioning platform is arranged on the motor supporting plate. One end of the high-precision positioning platform is connected with a servo motor. A motor connecting plate is arranged on the high-precision positioning platform. One end of the motor connecting plate is connected with the female die fixing plate. The manufacturing die and method for the variable-cross-section iron core have the beneficial effects that the female die fixing plate is controlled by controlling the high-precision positioning platform, so that a male die body and a female die body which are located on the same station are made to move synchronously in the material width direction to punch products, the length of the die is reduced, the feeding accuracy and stability are improved, and the working efficiency is improved.
Description
Technical field [0001] The present invention relates to the technical field of iron core manufacturing, in particular, to a variable-section iron core manufacturing mold and a variable-section iron core manufacturing method. Background technique [0002] At present, the production process of non-uniform cross-section iron core products is as follows: according to the different width of the parts, a single silicon steel sheet with various buckle riveting points is punched out, and then assembled by manual riveting through a fixture. The efficiency is low, and the product quality stability is poor. The external dimensions of the iron core are greatly affected by human factors. As manufacturers have increasingly strict requirements on product dimensions, this production process is difficult to meet the requirements of the product. [0003] The application number is 201210392737.3 discloses a non-uniform cross-section iron core punching device in a progressive die. This device has mor...
