[0027] The outer expansion part includes two mounting grooves, the mounting grooves are internally provided with deflection blocks 62, the deflection blocks 62 are provided with rotating parts in the middle, the deflection blocks 62 are respectively provided with contraction blocks 63 and outer expansion rods 66 at both ends, springs 64 are fixedly connected between the top of the contraction block 63 and the inner wall of the mounting groove, rolling balls 65 are rotatably inserted into the bottom of the contraction block 63, and extrusion pieces 67 are arranged on one side of the outer expansion rod 66.

[0028] A plurality of limiting blocks 68 are arranged on the surface of the outer expansion rod 66, and the surface of the insertion groove 61 is matched with the limiting blocks 68.

[0029] During the lifting of the winding disc 30 by the lifting assembly, the rotating cylinder 52 is inserted into the middle of the winding disc 30, after the top of the winding disc 30 contacts the contraction block 63, the contraction block 63 is extruded and contracted, so that the spring 64 is compressed and deformed, the contraction block 63 is deflected with the rotating part as the center, the outer expansion rod 66 moves, because the surface of the outer expansion rod 66 is provided with a plurality of limiting blocks 68 and the surface of the insertion groove 61 is matched with the limiting blocks 68, the outer expansion rod 66 is tilted and moves upward as a whole, the extrusion piece 67 contacts and is extruded and deformed with the inner surface of the winding disc 30, then the driving part two 51 drives the rotating cylinder 52 to rotate, the winding disc 30 rotates to feed the copper wire, when the winding disc 30 rotates, the rolling ball 65 at the bottom of the contraction block 63 rolls, so that the contraction block 63 and the surface of the winding disc 30 are prevented from being abraded by friction.

[0030] The feeding assembly does not affect the lifting work of the winding disc 30, the lifting winding disc 30 is sleeved on the surface of the rotating cylinder 52, the extrusion of the winding disc 30 surface on the outer expansion part is deformed and frictionally fixed in the winding disc 30, and the rotating cylinder 52 can drive the winding disc 30 to rotate to feed the straightening and shearing integrated machine 10.

[0031] Figure 3 The lifting plate 41 is internally circumferentially provided with a plurality of rolling wheels 71, and the rolling wheels 71 are rotatably matched with the surface of the winding disc 30.

[0032] During the rotation of the winding disc 30, the plurality of rolling wheels 71 at the bottom rotate, so that the winding disc 30 and the surface of the lifting plate 41 are prevented from being abraded by friction and cannot move, and the winding disc 30 is facilitated to quickly release the copper wire.

[0033] Working principle:

[0034] Before the flat copper wire is straightened and cut, the worker moves the winding disc 30 to the lifting plate 41, and the multiple rolling wheels 71 support the bottom of the winding disc 30. When the worker moves the winding disc 30, the winding disc 30 can be rolled to the top of the lifting plate 41 and laid down by its own characteristics. Then the driving part one 42 drives the screw rod 44 to rotate, and the sliding block 43 drives the lifting plate 41 to rise, so that the winding disc 30 is moved to the same working plane as the components of the straightening and cutting integrated machine 10. After the winding disc 30 is lifted to a certain height, the rotating cylinder 52 is inserted into the middle part of the winding disc 30.

[0035] When the top of the winding disc 30 contacts the contraction block 63, the contraction block 63 is extruded and contracted, so that the spring 64 is compressed and deformed. The contraction of the contraction block 63 causes the deflection block 62 to deflect around its rotating part. The outer expansion rod 66 moves upward as a whole, because the surface of the outer expansion rod 66 is provided with multiple limiting blocks 68 and the surface of the insertion slot 61 matches the limiting blocks 68. The extrusion piece 67 is in contact with the inner surface of the winding disc 30 and is extruded and deformed. Then the driving part two 51 drives the rotating cylinder 52 to rotate, so that the winding disc 30 rotates to feed the copper wire. The multiple rolling wheels 71 at the bottom of the winding disc 30 rotate at the same time, so as to avoid the friction between the winding disc 30 and the surface of the lifting plate 41.

[0036] When the copper wire passes through the straightening and cutting integrated machine 10, the bent copper wire is straightened by the straightening components in the straightening and cutting integrated machine 10, and then the cutting components in the straightening and cutting integrated machine 10 cut the straightened copper wire.
