[0065] The working process of this double-head crimping machine is as follows:

[0066] 1. The wire is fed through the wire feed assembly 2. When the wire is fed, the end of the wire is exposed from the spring mouth 211 and then moves toward the cutter assembly 705. The end of the wire is stripped by the stripping knife.

[0067] 2. The sheath in the vibrating plate containing the sheath passes through the material rail 303 and reaches the groove of the material distributor. Then the pressure cover 306 is closed to fix the sheath in the groove of the material distributor. At this time, the material distributor rises and blocks the outlet of the material rail 303.

[0068] 3. The rotary cylinder 308 drives the positioning needle 310 so that the positioning needle 310 faces the sheath in the groove of the material distribution seat. The slide cylinder 317 drives the rotary cylinder 308 to move toward the material distribution seat until the positioning needle 310 is inserted into the sheath in the groove of the material distribution seat.

[0069] 4. The pressure cover 306 is opened. At the same time, the rotary cylinder 308 moves toward the position of the first stripping clamp 311. The positioning pin 310 takes out the sheath. At this time, the first stripping clamp 311 is in the open state. The positioning pin 310 rotates 180 degrees to put the sheath into the first stripping clamp 311. The first stripping clamp 311 is closed. The rotary cylinders 308 and 308 move in the opposite direction to separate the positioning pin 310 from the first stripping clamp 311. At the same time, the first stripping clamp 311 is closed to fix the fixed sleeve.

[0070] 5. The wires with the stripped ends pass through the first wire entry block 215, the groove wheel, the second wire entry block 216, the fixing seat 210, the wire outlet guide 217 and the spring mouth 211 on the side wall of the gear seat 207, wherein the stripped end portion of the wire is flush with the end of the wire outlet guide 217 or does not expose the end of the wire outlet guide 217.

[0071] 6. The Y-axis base 204 moves along the first base plate 219 so that the spring mouth 211 is aligned with the first stripping clamp 311. Then, the first slide in the Y-axis base 204 moves toward the first stripping clamp 311. The outlet conduit 217 with the spring mouth 211 installed is inserted into the sheath of the first stripping clamp 311 along with the wires. The first cylinder 220 moves the spring mouth 211 away from the first stripping clamp 311 via the slider seat until the spring mouth 211 is separated from the first stripping clamp 311. At this time, the end of the wire is located in the sheath clamp.

[0072] 7. The first stripping clamp 311 is opened to complete the stripping operation.

[0073] 8. The incoming wire assembly 2 moves the sheathed wire to the terminal crimping mechanism 5 to perform the terminal crimping operation.

[0074] 9. The incoming wire assembly 2 moves the wire with the terminal and the sheath to the position of the cutter 705 assembly, the clamping clamp 809 clamps the wire, the cutter 705 assembly cuts the wire, and then the stripping knife strips the wire at the position where the wire is cut. At this time, the wire corresponds to the position of the second feeding device 4.

[0075] 10. After the sheath of the second feeding device 4 is moved into the second stripping clamp 401, the clamping clamp 809 inserts the stripped end of the wire into the sheath in the second stripping clamp 401 through the bell mouth 403 to complete the sheathing operation.

[0076] 11. Move the wire to position 5 of the terminal crimping mechanism for terminal crimping operation.

[0077] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
