Problems solved by technology
Background technology The stamping dies of oil gap pads are generally in the rear positioning mode. Although the specific dimensions of each mold are different, as long as they are installed, there must be a minimum punching size for the positioning plate. When the radial size of the coil is smaller than the minimum punching size After dimensioning, it is very difficult to make oil gap spacers, and it is difficult to ensure that the production progress is completed on schedule, which brings great inconvenience to the design and manufacturing process of transformer products

Embodiment Construction
[0010] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.
[0011] A punching die positioning plate for a transformer oil gap pad, including a mold 1 and a front positioning plate 2, the front positioning plate is fixed in front of the mold, the front positioning plate is a zigzag structure 3 with equal tooth spacing, and the spacing between each tooth is For the cutting size of each cardboard strip, the processing accuracy is ensured by stepping according to the tooth spacing, so that the cardboard strips are gradually aligned with each sawtooth, and the cardboard strips can be punched out into oil gap pads. The positioning plate of the punching die of the transformer oil gap pad is installed on the punching machine, replacing the rear positioning plate in the background technology, and punching an oil gap pad whose length is smaller than the minimum punching size.

The invention relates to a transformer oil clearance cushion block stamping positioning plate and belongs to the technical field of transformer production. The technical scheme includes that the plate comprises a die (1) and a front positioning plate (2), wherein the front positioning plate is fixed to the front of the die, the front positioning plate is in a saw-tooth-shaped structure (3) of which distances among teeth are the same, each of distances among teeth is a blanking size of every card board strip, the process accuracy is guaranteed through saw tooth distance stepping, card board strips can align to every saw tooth, and oil clearance cushion blocks can be stamped on card board strips. The plate has the advantages that the front positioning plate is arranged, a rear positioning plate and the die cannot block the falling path of the clearance cushion blocks, the stamping of short clearance cushion blocks can be achieved, a front positioning saw tooth tool of a transformer oil clearance cushion block stamping is used, oil clearance cushion blocks of small sizes can be punched through a punch, the production efficiency is improved greatly and oil clearance cushion blocks of any sizes can be produced.
Description
technical field [0001] The invention relates to a die positioning plate for a transformer oil gap cushion block, and belongs to the technical field of transformer production. Background technique [0002] In transformer production, due to the uncertainty of the radial dimension of the transformer coil, the length dimension of the oil gap spacer is also uncertain. Background technology The stamping dies of oil gap pads are generally in the rear positioning mode. Although the specific dimensions of each mold are different, as long as they are installed, the positioning plate must have a minimum punching size. When the coil radial size is smaller than the minimum punching size After dimensioning, it is very difficult to make oil gap pads, and it is difficult to ensure that the production progress is completed on schedule, which brings great inconvenience to the design and manufacturing process of transformer products. Contents of the invention [0003] The purpose of the pre...
