Description

Technical Field

[0002] The feeding abnormality sensing device of the progressive die is a device used to detect and control the feeding position and integrity of the progressive die during the production process. It consists of an infrared transmitter and a receiver. The upper die is equipped with an infrared transmitter, and the corresponding position of the lower die is embedded with an infrared receiver. When the positioning holes on the material plate are correctly aligned with the infrared receiver, the infrared rays can pass smoothly; if the feeding is too much or insufficient, the infrared rays will be blocked.

When the sensor 2 needs to be turned on, the connection between the clamping rod 21 and the limit hole 41 is first released, and then the screw rod 25 is rotated clockwise. The rotation of the screw rod 25 will drive the movable block 26 to move in the direction close to the sensor 2, thereby driving the positioning plate 27 and the hexagonal rod 4 to move together, so that the sensor 2 is in a powered-on state. Conversely, the screw rod 25 can be rotated counterclockwise to achieve the reverse movement of the hexagonal rod 4 to achieve the power-off of the sensor 2.

Then, the movable plate 13 continues to move in the same direction. The meshing of the rack 28 and the gear 29 drives the screw rod 25 to rotate clockwise, so that the hexagonal rod 4 moves toward the direction close to the sensor 2, so that the sensor 2 is powered on and works. During this process, the abutment plate 36 and the cross plate 23 are always in contact with the vertical plate 37 and the limit plate 22 respectively, and one side of the positioning frame 31 will not be engaged with the positioning groove 321, which is convenient for the screw rod 25 and the gear 29 to rotate. After the strip 28 is no longer in contact, the hexagonal rod 4 is no longer moving, and the other limiting hole 41 is also moved to the top of the clamping rod 21, and the moving plate 13 is continued to be moved. The movement of the moving plate 13 will drive the abutment plate 36 to no longer contact the vertical plate 37, and then under the action of the second spring 35, one end of the positioning frame 31 will be driven to re-engage with the positioning groove 321, and then the cross plate 23 and the limiting plate 22 are released from the abutment state, and the limiting plate 22, the lifting plate 19 and the clamping rod 21 move upward under the action of the first spring 20 so that the clamping rod 21 is re-engaged with the other limiting hole 41, thereby ensuring the stability of the hexagonal rod 4. At the same time, the movement of the moving plate 13 will The connecting rod 14 is driven to move along the transverse groove 102. The movement of the connecting rod 14 will drive the inclined block 15 to move along the movable plate 16. The movable plate 16 is provided with a groove corresponding to the inclined block 15. Therefore, the movement of the inclined block 15 will drive the movable plate 16 to move away from the sensor 2, thereby driving the fixed rod 18 and the movable frame 11 to move. The movement of the movable frame 11 will achieve the two baffles 85 moving away from each other through cooperation with the swing rod 9 and the disk 82. The fixed block 17 provides support for the movable plate 16. Similarly, when the baffle 85 needs to abut, the movable plate 13 can be moved along the movable groove 101 in the direction away from the hexagonal rod 4.
