Embodiment Construction
[0022] refer to Figure 1 ~ Figure 4 , a suspension-type material guide device for a progressive blanking die of the present invention, comprising a longitudinal material guide plate 1, a spacer 11, a lifting support column 2, and a spring 22, wherein: the longitudinal material guide plate 1 is rectangular and long A block-shaped steel component; the pad 11 is a rectangular block-shaped steel component;
[0023] The lifting support column 2 is a rectangular columnar steel component; the upper end of the lifting support column 2 is provided with a gap that is a right-angled step in a side view and is called a bayonet 21;
[0024] The spring 22 is a cylindrical helical compression spring;
[0025] The bottom of the longitudinal material guide plate 1 is evenly spaced with a number of pads 11, and the two parallel longitudinal material guide plates 1 are supported by the pads 11, symmetrical to the center line in the left and right direction of the die carrier plate 01, protrudi...

The invention discloses a suspended material guide device of a progressive blanking die. The suspended material guide device of the progressive blanking die comprises longitudinal material guide plates (1), cushion blocks (11), a lifting supporting column (2) and a spring (22). According to the device composed of the components, a bayonet is arranged at the upper end of the lifting supporting column; the two longitudinal material guide plates with the multiple cushion blocks evenly distributed and lined on the lower faces at intervals are suspended and fixed on the front side and the rear side of the upper face of a concave die bearing plate respectively; gaps between the concave die bearing plate and the longitudinal material guide plates are suspension gaps; the lifting supporting column is supported by the spring and slide in a groove located in the concave die bearing plate, and the upper end of the lifting supporting column makes elastic contact with the lower faces of the longitudinal material guide plates. In work, a material strip is clamped between the bayonet and the lower faces of the longitudinal material guide plates in a sliding mode; in the blanking motion, the material strip is elastically supported by the lifting supporting column to be lifted; when the material strip is fed and longitudinally moved, the longitudinal material guide plates stop the edge of the material strip from disengaging upward, the suspension gaps are convenient to use for visual inspection and clearing away blanking scraps according to the technical scheme, and thus the die achieves the purposes of smooth feeding and automatic feeding starting and the purpose that the blanking scraps can be found and cleared away easily.
Description
technical field [0001] The invention relates to a material guide device for a progressive blanking die, in particular to a progressive blanking device for guiding the movement of a material plate in a progressive blanking die for automatically and continuously punching and forming motor stators and rotor core chips Suspended material guide device for the mold. Background technique [0002] The progressive blanking die for automatic continuous punching and forming of motor stator and rotor core chips, referred to as the core progressive die, is equipped with a core progressive die for clamping and guiding the strip-shaped silicon steel plate to move up and down with the punching of the die. , at the same time, the material guide device that moves horizontally with the drive of the feeder, the material guide device in the prior art has two structural forms, one is the lifting pin type, refer to Figure 5 , that is, a spring-supported cylindrical lifting pin is installed in the...
