Description

Technical Field

[0001] The utility model relates to the technical field of movable cutting angle induction switches, in particular to a movable cutting angle induction switch. Background Art

[0002] In the stamping continuous die, an anti-misdelivery detection switch is needed to detect whether the material strip is misplaced. Commonly used anti-misdelivery detection switches are probe type and photoelectric type. The material strip of the drawn product generally has a higher floating material, and the material strip is mostly wavy, so the probe is easy to be inserted off-center. The photoelectric type is used. Due to the large amount of oil stains in the deep drawing mold, the photoelectric lens is easily obscured by the oil stains. It can be seen from the above that the above two anti-misdelivery detection switches are prone to misjudgment during detection, and the detection accuracy is not ideal, which cannot meet the use requirements.

[0024] Working principle: When in use, the floating pin 1 is set to always hold the material belt 2 and move it up and down. At the same time, the floating pin 1 also plays a role in guiding the floating material. When the floating pin 1 drives the material belt 2 to float upward, (the driving principle of the floating pin 1 to float upward is the existing technology and is not elaborated here), the compression spring 11 in the compressed state drives the corresponding movable guide rod 6 to move upward, and the movable guide rod 6 drives the L-shaped sensing pin 5 to move upward through the cover plate 4 and the support plate 8 in turn. The L-shaped sensing pin 5 drives the material belt 2 to float upward synchronously. At the same time, the feeding mechanism on the punch press pushes the material belt 2 to the right, so that the material belt 2 runs to the right between the cover plate 4 and the support plate 8. When the material belt 2 moves to the right, it will drive multiple cutting corners 3 to move to the right. When one of the cutting corners 3 moves to the right, it will squeeze the L-shaped sensing pin 5. Under the squeezing force, the L-shaped sensing pin 5 moves forward, and the L-shaped sensing pin 5 moves forward. The first spring 7 is stretched, and when the material strip 2 moves to the right to the correct position, the elastic force of the first spring 7 in the stretched state will drive the L-shaped sensing pin 5 to be stuck in an aligned cutting corner 3. If the material strip 2 is misaligned, the L-shaped sensing pin 5 cannot be aligned with the cutting corner 3, and thus cannot be stuck in the cutting corner 3. The forward-moving L-shaped sensing pin 5 will squeeze the microswitch 9, triggering the microswitch 9 to turn on. The microswitch 9 will transmit information to the emergency stop controller of the punch press through the lead 10. The emergency stop controller of the punch press controls the feeder on the punch press to stop feeding in time to avoid damaging the product and the mold due to the misalignment of the material strip 2. The way of triggering the microswitch 9 to turn on by extrusion drive will not be affected by oil pollution, and with the guidance of the cover plate 4, the L-shaped sensing pin 5 will not deviate during the movement, thereby achieving the effect of stable detection of misalignment and improving detection accuracy.
