Placing the copper wire 146 to be cut on the workbench 144, then starting a hydraulic cylinder (comprising an upper hydraulic cylinder 100 and a hydraulic cylinder), and synchronously operating the upper hydraulic cylinder 100 and the lower hydraulic cylinder 102 to drive the upper cutter 108 and the lower cutter 110 to cut the upper surface and the lower surface of the copper wire 146 respectively, wherein only one surface (front surface) of the upper cutter 108 and the lower cutter 110 is an inclined surface, the other surface (back surface) of the upper cutter 108 and the lower cutter 110 is a plane, and the upper cutter 108 and the lower cutter 110 are reversely arranged, so that two sections of the copper wire 146 to be cut are respectively parallel to the upper plane 112 and the lower plane 116 after cutting is finished, thereby being beneficial to avoiding burrs generated on the sections of the copper wire 146 to be cut, or being beneficial to reducing the size and sharpness of burrs generated on the sections of the copper wire 146 to be cut, being beneficial to reducing the inclination degree of the sections of the copper wire 146 to be cut, and improving the flatness of the sections of the copper wire 146 to be cut; the principle of the above scheme of this embodiment is that the burr formed by unavoidable extrusion is concentrated between the upper inclined surface 114 and the lower inclined surface 118 and separated from the two sections of the copper wire 146 to be cut, so that the burr is prevented from adhering to the sections of the copper wire 146 to be cut, and the burr-bearing part is separated in the form of a blanking 148; although the above solution of the present embodiment may result in a waste of a part of the material, the thickness of the upper cutter 108 and the lower cutter 110 is smaller, so that the axial length of the blanking 148 where the burrs are located is smaller, and the waste degree is very low, and compared with the loss caused by the damage of the burrs to scratch the paint layer and the product failure, the loss caused by the waste is basically negligible.
Since the cutting edge is necessarily passivated after a period of time, and the passivated shape is difficult to predict, the passivated shape is not changed by the pre-passivation treatment in this embodiment after the subsequent use, so that the shearing effect is prevented from being affected by the irregular deformation (for example, the lower edge of the upper plane 112 bends towards the back of the cutter 108, which may cause burrs on the section formed by shearing the lower edge of the upper plane 112).
In some exemplary implementations of the present embodiment, the blade thickness of the upper cutter 108 is the same as the blade thickness of the lower cutter 110, the upper plane 112 is located at the back of the upper cutter 108, the upper bevel 114 is located at the cutting edge portion of the front face of the upper cutter 108, the lower plane 116 is located at the back of the lower cutter 110, the lower bevel 118 is located at the cutting edge portion of the front face of the lower cutter 110, the back of the upper cutter 108 is located at the same vertical plane as the front face of the lower cutter 110, and the front of the upper cutter 108 is located at the same vertical plane as the back of the lower cutter 110.
The length of the blanking 148 along the axial direction of the copper wire 146 to be cut can be reduced, namely, the blanking 148 amount is reduced, and the waste is reduced.
In some exemplary implementations of the present embodiment, the vertical distance between the upper edge of the upper bevel 114 and the lower edge of the upper plane 112 is greater than the diameter of the copper wire 146 to be cut; the vertical distance between the lower edge of the lower bevel 118 and the upper edge of the lower plane 116 is greater than the diameter of the copper wire 146 to be cut.
As shown in fig. 7, in the process that the lower edge of the upper plane 112 is sheared to the lower surface of the copper wire 146 to be cut and the upper edge of the lower plane 116 is sheared to the upper surface of the copper wire 146 to be cut, a certain distance is kept between the upper inclined plane 114 and the upper edge of the lower plane 116 all the time, the extrusion force applied to the blanking 148 in the shearing process is gradually increased to deform, the blanking 148 can be extruded from the notches on the upper inclined plane 114 and the upper edge of the lower plane 116 after being extruded and deformed, and similarly, the blanking 148 can be extruded from the notches on the lower inclined plane 118 and the lower edge of the upper plane 112 after being extruded and deformed.

The sliding connection between the inner side surface of the lower channel 120 and the back surface of the lower cutter 110 helps to guide and support the upper edge of the lower plane 116 during the shearing process, so as to avoid deformation of the upper edge of the lower plane 116 due to excessive extrusion force (burrs are easily formed on the shearing section after deformation).
In some exemplary embodiments of the present embodiment, a discharge channel 122 is provided on one inner side surface of the lower channel 120 in front contact with the lower cutter 110, and the discharge channel 122 is disposed obliquely, and one end of the discharge channel 122 near the lower channel 120 is higher than the other end.
After shearing, the lower cutter 110 moves downward to withdraw from between the two sections of the copper wire 146 to be cut, the blanking 148 slides downward along the lower inclined surface 118, and when the lower edge of the lower inclined surface 118 is aligned with the discharging channel 122, the lower end of the blanking 148 slides into the discharging channel 122 and is discharged from the discharging channel 122, so that the blanking 148 is prevented from accumulating in the lower channel 120.
As shown in fig. 8, in some exemplary implementations of this embodiment, the device further includes a pressing block 124, an upper channel 126 is disposed on an upper surface of the pressing block 124, the upper channel 126 penetrates the pressing block 124 along a vertical direction, a front surface of the upper cutter 108 and a back surface of the upper cutter 108 are respectively slidably connected with two opposite inner side surfaces of the upper channel 126, a guiding groove 128 is disposed on a lower surface of the mounting plate, an upper end of the pressing block 124 is slidably connected with an inner wall of the guiding groove 128 along the vertical direction, a spring 130 is disposed in the guiding groove 128, one end of the spring 130 is fixedly connected with an inner wall of the guiding groove 128, the other end of the spring 130 is fixedly connected with an upper surface of the pressing block 124, a telescopic direction of the spring 130 is vertically set, and when the lower surface of the pressing block 124 is not subjected to extrusion force of the copper wire 146 to be cut, the lower surface of the pressing block 124 is lower than the lower edge of the upper plane 112.
Before the upper cutter 108 contacts with the upper surface of the copper wire 146 to be cut, the pressing block 124 presses the copper wire 146 to be cut on the workbench 144, so that the copper wire 146 to be cut is fixed, and tilting of the copper wire 146 to be cut due to extrusion in the cutting process (the tilting of the copper wire 146 to be cut can affect the flatness of a cut section) is avoided.
