[0018] See also Figure 1-7The present embodiment is an intelligent material arrival detection device for a bending machine, comprising a support seat, one end of the support seat is provided with a connecting portion 3 connected to the bending machine, the other end is provided with a linear track 6, a slide seat 5 is mounted on the linear track 6, a material blocking seat 4 is fixedly mounted on the slide seat 5, a return spring 15 is mounted between the material blocking seat 4 and the support seat, a fixed plate 2 is provided on the support seat, a movable gap 7 is provided between the fixed plate 2 and the material blocking seat 4, a signal contact A is provided on a side of the fixed plate 2 facing the material blocking seat 4, a signal contact B corresponding to the position of the signal contact A is provided on a side of the material blocking seat 4 facing the fixed plate 2, one end of the signal contact A is connected to a communication cable A8, one end of the signal contact B is connected to a communication cable B9, and the communication cable A8 and the communication cable B9 are respectively connected to the control system of the bending machine.

[0019] Furthermore, the signal contact A adopts a copper screw A10, and the signal contact B adopts a copper screw B11. The copper screw A10 is directly connected to the communication cable A8. An insulating part 12 is provided between the copper screw A10 and the fixing plate 2. The copper screw B11 is directly connected to the material stop seat 4, and the communication cable B9 is installed on the material stop seat 4.

[0020] Furthermore, a through hole is provided on the fixing plate 2 corresponding to the copper screw A10, and the copper screw A10 passes through the through hole without contacting the fixing plate 2. One end of the copper screw A10 is fixed by a nut, and an insulating pad is installed at each end of the copper screw A10, so that the copper screw A10 is not directly connected to the support seat.

[0021] Furthermore, the copper screw A10 protrudes from the surface of the fixing plate 2 , and the copper screw B11 protrudes from the surface of the material blocking seat 4 .

[0022] Furthermore, a limiting bolt 13 is installed on the material blocking seat 4, one end of the limiting bolt 13 is fixedly connected to the material blocking seat 4, and the other end of the limiting bolt 13 passes through the fixing plate 2 and is provided with a nut, and the limiting bolt 13 is slidably connected to the fixing plate 2.

[0023] Furthermore, an adjusting bolt 14 is installed on the material blocking seat 4, and a through hole is provided in the material blocking seat 4 corresponding to the adjusting bolt 14. One end of the adjusting bolt 14 passes through the through hole and is threadedly connected to the fixing plate 2, and the nut of the adjusting bolt 14 is in close contact with the material blocking seat 4.

[0024] The working principle of the utility model is as follows: when the intelligent unit is used for bending, after the plate contacts the positioning surface of the material blocking seat 4, the plate pushes the material blocking seat 4 to move, and the material blocking seat 4 moves with the slide 5 on the linear guide rail toward the fixed plate 2. At the same time, the reset spring 15 is compressed until the copper screw B11 on the material blocking seat 4 contacts the copper screw A10 on the fixed plate 2, so that the communication cable A8 is connected to the communication cable B9. At this time, the main control system of the bending machine will obtain the signal that the plate is in place, and then execute the bending action of this step.

[0025] When the plate is bent, the force exerted by the plate on the material stop seat 4 disappears, and the compressed return spring 15 rebounds to drive the material stop seat 4 to return and move until the nut of the limit bolt 13 contacts the fixed plate 2 and stops. At this time, the signal contact A is disconnected from the signal contact B, and the corresponding communication cable A8 is also disconnected from the communication cable B9, and the arrival signal of the bending machine main control system is disconnected.

[0026] When manual bending is required, the bending machine is switched to manual bending mode. At this time, no plate arrival signal is required. Instead, the operator manually pushes the plate onto the material blocking seat 4. At this time, in order to prevent the movable gap 7 between the material blocking seat 4 and the support seat from affecting the bending accuracy of the plate, it is only necessary to twist the adjustment bolt 14 to make the material blocking seat 4 close to the support seat until the copper screw A10 and the copper screw B11 are in contact.
