Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a material guiding and ejecting device for automatic stacking of iron core progressive dies. Background Technology

[0002] In electric motors and electrical products, the silicon steel sheet stacked core is one of the important components. The core accounts for 25%-30% of the product weight, and its quality has a direct impact on the product performance. The core is generally made of silicon steel sheets with high magnetic permeability and low loss. To reduce losses, the core is required to be divided into thin sheets along the axial direction, with a thickness of 0.35mm or 0.5mm. Therefore, a core can be composed of dozens to hundreds of silicon steel sheets. Therefore, the processing volume of iron core laminations is very large. In the past, the iron core processing methods involved many steps and manual operations, resulting in low production efficiency, high labor intensity for workers, and difficulty in guaranteeing the stacking quality. With the development of industrial technology, progressive die production on high-speed punch presses has been adopted, trending towards high-speed automated production. The stacking of iron cores has gradually transitioned from traditional processing methods to automatic stacking. The automatic stacking progressive die technology for iron cores began to be promoted and applied in industrialized countries in the late 1970s. Automatic stacking technology is suitable for mass production of electric motors and electrical products. The applicable punching speed can reach 140-350 times / min, the life of a single grinding can reach more than 1 million times, and the total life of the die can reach more than one trillion times. Automatic stacking technology can be used for stators, rotors, and triangular iron cores of electric motors.

[0003] When using existing automatic stacking progressive dies for iron cores, the strip material being processed tends to jump upwards as it is being transported forward, and the guiding and positioning accuracy of the strip material is low, which affects the efficiency and accuracy of product processing. In addition, existing automatic stacking progressive dies for iron cores do not have a strip material lifting device. When the strip material punches out of the protrusion, it often sticks to the upper surface of the die, making it impossible to feed.

[0004] Existing patent (publication number: CN202398703U) discloses a guide for an automatic stacking progressive die for iron cores. This utility model discloses a guide and ejector device for an automatic stacking progressive die for iron cores, involving a mechanical device including symmetrically arranged ejector pins. A stepped through hole is opened on the lower die base, and the lower part of the ejector pin is sleeved in the stepped through hole and can slide relative to the stepped through hole. A through hole is opened on the die cavity, and the upper part of the ejector pin is sleeved in the through hole and can slide relative to the through hole. The upper end face of the ejector pin is higher than the upper surface of the die cavity. A return spring is provided on the part of the ejector pin sleeved in the stepped through hole. Two guide plates are arranged opposite each other on the upper surface of the die cavity. The two sides of the guide plates facing each other are provided with outwardly extending protrusions in a direction perpendicular to the side. This utility model has high guiding and positioning accuracy for strips, prevents strips from jumping up, and can maintain a certain gap between the strip and the die cavity, which is beneficial for the guide pin to guide the strip. It is very practical.

[0005] In view of the above problems, the existing patent provides a solution, but the ejector pin in the above patent will appear oil shortage after long time repeated lifting and friction, resulting in lifting not smooth or even jam, which will affect the normal use of the device, at the same time, the internal structure of the guide plate does not monitor the position and horizontal state of the strip material, which may cause the strip material to be placed in an unstable position, thereby affecting the precision and quality of product processing.
