The invention discloses a progressive die for manufacturing a bimetallic sheet support. The progressive die comprises a first stamping die, a second stamping die, a first limiting die (36), a second limiting die (38), a positioning part (35) and an electric screw driver (37); a stamping groove is formed in the face, facing a material strip, of the first stamping die, and the second stamping die can move relative to the first stamping die and is provided with a stamping head which can be embedded into the stamping groove in a matched mode; a limiting groove (362) is formed in the face, facing the material strip, of the first limiting die, and the second limiting die can move relative to the first limiting die and is provided with a limiting head (382) which can be embedded into the limiting groove in a matched mode; the positioning part can stretch into a gap formed between a first adjusting plate (622) and a second adjusting plate (624) and abut against the second adjusting plate; the electric screw driver can enable an adjusting bolt (626) to be arranged on the first adjusting plate in a penetrating mode and connected to the second adjusting plate in a threaded mode till the first adjusting plate abuts against the positioning part. According to the progressive die, the production efficiency can be improved, and the specifications of finished products can be consistent.
Description
technical field [0001] The invention relates to a continuous mold, in particular to a continuous mold for producing bimetallic brackets. Background technique [0002] In order to realize the leakage protection function, a bimetal strip tripping device is installed in the switchgear such as a circuit breaker. In the bimetal strip tripping device, the bimetal strip is fixed by the bimetal strip bracket, and the bimetal strip will be deformed when heated to realize the tripping action. [0003] The manufacturing process of the existing bimetal support needs to be completed by a continuous die. The continuous die has a plurality of stations from its feed end to its discharge end, and the dies on each station can realize different stamping actions. When making the bimetal sheet bracket, the material strip is fed from the feed end of the continuous die, and the material strip is moved sequentially along the direction from the feed end to the discharge end. Each movement, the mold...
