As for the electrode, the electrode of the present embodiment is an electrode for an ignition device. The electrode of the embodiment comprises a substrate 19 and a core material 20, wherein the substrate 19 is made of a ceramic material, and the core material 20 is made of a metal bar material. After the core 20 is embedded and fixed to the base 19, one end of the core 20 protrudes out of the base 19 and forms a workpiece of the shearing and bending machine of the present embodiment. One end of the core 20 protrudes out of the base 19 in order to bring the end of the core 20 closer to the location where ignition is needed, so as to improve the ignition effect. The shearing and bending machine of the present embodiment is configured to bend and shear the end of the core material 20 protruding out of the base 19 to a predetermined length, thereby forming the end of the core material 20 protruding out of the base 19 into a predetermined shape and length.

With respect to the jig 3, the jig 3 of the present embodiment can fix the base 19, thereby fixing one end of the core 20. The clip 3 of the present embodiment may be replaced with any clip 3 known in the art.

Regarding the cutting blade 6, the cutting blade 6 of the present embodiment cooperates with one end surface of the positioning sleeve 5 to form a shearing mechanism. The cutter 6 may be replaced by other shearing mechanisms known in the art.

Regarding the first driving mechanism 1, the first driving mechanism 1 of the present embodiment is a stepping motor, and can drive the fixture 3 to rotate by a specific angle, so that the bending degree of the core material 20 of the electrode can be controlled. The first drive mechanism 1 can also be replaced by other rotation mechanisms known in the art.

With regard to the second driving mechanism 2, the second driving mechanism 2 of the present embodiment drives the shearing device to translate along the axis direction of the positioning hole 8, so that the core material 20 of the electrode can be inserted into the positioning hole 8 along the axis direction of the positioning hole 8. The second drive mechanism 2 may be implemented by any linear motion mechanism known in the art. The second driving mechanism 2 of the present embodiment includes two rail-slider mechanisms parallel to each other, and the rail-slider mechanisms enable the shearing apparatus to smoothly perform translation.

Regarding the third driving mechanism 7, the third driving mechanism 7 of the present embodiment can drive the cutting knife 6 to translate, so that the cutting knife 6 and the positioning sleeve 5 generate a shearing action. The third drive mechanism 7 may be implemented by any linear drive mechanism known in the art.

After the electrode is fixed in the fixture 3, the second driving mechanism 2 drives the shearing device to translate along the axis direction of the positioning hole 8, so that one end of the core material 20 of the electrode passes through the positioning hole 8 and extends out of the positioning sleeve 5. Then the third driving mechanism 7 drives the cutter 6 to move along the end face of the positioning sleeve 5 and generate a shearing action, so that the part of the core material 20 extending out of the positioning sleeve 5 is cut off. At this time, the clamp 3 and the positioning sleeve 5 respectively form constraints on two ends of the core material 20, and then the first driving mechanism 1 drives the clamp 3 to rotate around the rotating shaft 4, so that the core material 20 is bent.

The second driving mechanism 2 can drive the positioning sleeve 5 to realize positioning between the shearing device and the core material 20, the third driving mechanism 7 can drive the cutter 6 to realize shearing of the core material 20 by the shearing device, and the first driving mechanism 1 can drive the clamp 3 to realize bending of the core material 20. According to the technical scheme, the positioning, shearing and bending of the core material 20 can be continuously completed under the condition that the electrode is not separated from the clamp 3 and the positioning sleeve 5, so that the clamping and positioning times are minimized, the working efficiency is improved, the processing precision is improved, and the labor intensity of operators can be reduced.

Regarding the positioning groove 9, the surface of the fixture 3 of the embodiment is recessed inwards to form the positioning groove 9, so that the substrate 19 of the electrode can be conveniently embedded into the positioning groove 9 from the outside of the positioning groove 9, and the substrate 19 can be quickly assembled, disassembled, positioned and fixed. The base 19 of this embodiment is wrapped outside the core 20, the base 19 is rod-shaped, the side of the base 19 is provided with a plurality of bumps 21, and the bumps 21 protrude outwards from the side of the base 19. The positioning groove 9 of the present embodiment is a through groove, when one end of the substrate 19 is inserted into the positioning groove 9, the protrusion 21 on the substrate 19 can be clamped outside the positioning groove 9, and the substrate 19 can be prevented from sliding in the positioning groove 9 along the length direction of the positioning groove 9, so that the substrate 19 can be reliably positioned and fixed in the fixture 3.

As for the first driving mechanism 1, the first driving mechanism 1 of the present embodiment is a stepping motor surface, and the rotation angle of the jig 3 is controllable. The first driving mechanism 1 can also be replaced by other driving structures with controllable rotation angle in the prior art. By controlling the rotation angle of the clamp 3, the bending degree of the core material 20 is controllable, which is beneficial to enlarging the processing range of the shearing and bending machine and improving the universality.

Regarding the positioning hole 8, the radial dimension of the end of the positioning hole 8 facing the fixture 3 is larger than the end of the positioning hole 8 facing away from the fixture 3, the radial scale of the positioning hole 8 continuously changes and forms an hourglass-shaped transition surface, so that the core material 20 of the electrode is more easily inserted into the positioning hole 8, the positioning hole 8 is compatible with a larger position error between the fixture 3 and the positioning sleeve 5, and the possibility of dislocation and positioning failure between the core material 20 and the positioning hole 8 is favorably reduced.

In the process of positioning the positioning hole 8 and the core material 20 with each other, the core material 20 is stationary relative to the jig 3, and the positioning sleeve 5 is moved relative to the jig 3.

Regarding the third driving mechanism 7, the third driving mechanism 7 of the present embodiment is an air cylinder, and the third driving mechanism 7 can be replaced by other linear power mechanisms in the prior art, including but not limited to a hydraulic cylinder and an electric motor. The third driving mechanism 7 of this embodiment is a cylinder, so that the movement speed of the cutter 6 is fast, which is beneficial to improving the processing efficiency.

Regarding the lever 10, the middle part of the lever 10 of this embodiment is fixed by hinging, and the moment arm between the hinge point of the third driving mechanism 7 and the lever 10 is larger than the moment arm between the hinge point of the cutter 6 and the lever 10, so that the cutter 6 can output a larger shearing force, which is beneficial to improving the shearing capability of the cutter 6.

When the shearing action is executed, the third driving mechanism 7 of the embodiment drives one end of the lever 10 to move downwards, so that the cutting knife 6 moves upwards synchronously along one end of the positioning sleeve 5, and a shearing action is generated between the cutting knife 6 and the positioning sleeve 5.
