A metal strip 6 is transported to the feeding track 5 by the feeding mechanism 1, and after the slotting mechanism cuts and slots the metal strip 6 on the feeding track 5, the slotted metal strip 6 is unloaded by the unloading mechanism;

[0025] Two pressing mechanisms 4 are arranged on the feeding track 5, and the two pressing mechanisms 4 are respectively arranged on both sides of the slotting mechanism. The pressing mechanisms 4 press and position the metal strip 6, and the slotting mechanism slots the metal strip 6 pressed and positioned by the two pressing mechanisms 4 while the two pressing mechanisms 4 transport the metal strip 6.

[0026] The present invention controls the speed and accuracy of grooving by conveying the metal strip 6 through the loading mechanism 1 and the unloading mechanism; the grooving mechanism cuts and grooves the metal strip 6 on the feeding track 5, and has a high degree of automation. The grooving mechanism grooves the metal strip 6 pressed and positioned by the two pressing mechanisms 4, while the two pressing mechanisms 4 convey the metal strip 6, so that the grooving accuracy can be met while synchronous processing can be achieved, which greatly improves the production efficiency and can create more economic benefits for the enterprise.

[0027] The slotting mechanism includes a moving module 3, a slotting motor 31 and a slotting cutter head 32. The moving module 3 is drivingly connected to the slotting motor 31.

[0029] The slotting cutter head 32 includes a cutter head seat 321 and an assembly shaft, and the assembly shaft is arranged on the cutter head seat 321. The slotting tool includes a plurality of saw blade milling cutters 323, and the plurality of saw blade milling cutters 323 are sleeved on the assembly shaft. A fixed block is arranged between adjacent saw blade milling cutters 323. The chip cutting edge of one saw blade milling cutter 323 of two adjacent saw blade milling cutters 323 is arranged correspondingly to the chip removal groove of the other saw blade milling cutter 323. The adjacent chip cutting edges and chip removal grooves correspond to each other so that the chip debris can be removed in time, and the heat generated by the chip can be discharged at the same time. The plurality of saw blade milling cutters 323 can not only perform chip cutting and slotting synchronously, but also reduce cutting resistance, reduce blade wear, and extend the service life of the saw blade milling cutter 323.

[0030] Moreover, the length of the chip cutting edge of the saw blade milling cutter 323 on the inner and outer sides is greater than the length of the chip cutting edge of the saw blade milling cutter 323 between the inner and outer saw blade milling cutters 323, so that the debris generated by grooving can be discharged in time and will not accumulate, making the surface of the workpiece groove smooth, avoiding the generation of burrs and knife marks, and improving the processing quality.

[0031] A plurality of saw blade milling cutters 323 are mounted on the assembly shaft, so that the effect of processing a plurality of slots at a time can be achieved.

[0032] The feeding mechanism 1 includes a feeding frame, a first roller group 11 and a second roller group 12. The first roller group 11 is connected to the feeding frame through an adjusting component 13. The second roller group 12 is arranged on the feeding frame.

The third roller group 21 is connected to the unloading frame through an adjusting component 23. The fourth roller group 22 is arranged on the unloading frame. A unloading channel for the metal strip 6 to pass through is arranged between the third roller group 21 and the fourth roller group 22. The unloading motor 24 is arranged on the unloading frame. The unloading motor 24 is drivingly connected to the third roller group 21 and the fourth roller group 22. The unloading motor 24 drives the third roller group 21 and the fourth roller group 22 to synchronously convey the metal strip 6. The adjusting component 23 is exactly the same as the adjusting component 13 of the loading mechanism 1.

[0036] The pressing mechanism 4 includes a pressing plate 41 and a pressing roller 44. A pressing cylinder 42 is provided on the pressing plate 41. A roller frame 43 is provided at the end of the piston rod of the pressing cylinder 42. The pressing roller 44 is rotatably mounted on the pressing roller 44. The pressing roller 44 is driven by the pressing cylinder 42 to abut against the metal strip 6.

[0037] The pressing mechanism 4 also includes a driving component, which includes a driving motor 45. The driving motor 45 is connected to the roller frame 43 via a mounting seat.

The driving motor 45 drives the pressing roller 44 that is in contact with the metal strip 6 to rotate, thereby driving the metal strip 6 to be transmitted on the feeding track 5.

[0038] Since the resistor strip 62 targeted by the present application is of an E-shaped structure and the conventional material discharge side pulling method is adopted to directly perform multiple cutting and grooving, the resistor strip 62 will have a groove body 63 cut at each grooving position during the grooving process. Since the grooving close to the trunk position 61 reduces its supporting force, the resistor strip 62 will be subjected to uneven force, and the resistor end far from the trunk will bend, causing damage to the resistor.

[0039] The material pressing mechanism 4 of the present invention conveys the metal material strip 6 while pressing the positioned metal material, cutting the material strip in sections and conveying it continuously, ensuring that the resistance material strip 62 is subjected to uniform force during the chip cutting process.

[0040] It also includes a detection mechanism 55, which is arranged at the discharge end of the feeding track 5. The detection mechanism 55 includes a detection frame 56 and a detection cylinder 57. The detection cylinder 57 is arranged on the detection frame 56. The piston rod end of the detection cylinder 57 is provided with a detection sensor 58.

[0041] The detection sensor 58 is used to monitor the depth and width of the groove of the metal strip 6. If the measured groove specification exceeds the set threshold, the detection signal feedback is transmitted to the drive motor 45 to correct the conveying speed of the pressure roller 44, the mobile module 3 adjusts the relative position of the groove cutter head 32, and the groove motor 31 changes the output speed, so as to achieve the effect of timely repairing the groove accuracy.
