[0021] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0022] Combination Figure 1-3As shown, an automatic straightening and cutting coil wire feeding machine includes a wire feeding mechanism 1, a straightening mechanism, a cutting mechanism 2, and a trolley. The coil 4 is disposed on the drum 3 of the wire feeding mechanism 1. The trolley is equipped with clamps that clamp one end of the coil 4.

[0023] The wire feeding mechanism 1 is connected to the track 5 and moves back and forth. One end of the track 5 is provided with a driving device 6 for driving the wire feeding mechanism 1 to move. The straightening mechanism is located on one side of the track 5. The straightening mechanism consists of a base 7 and two mounting plates 8 that are connected to the base 7. Straightening wheel sets 9 are respectively provided on the two mounting plates 8. The cutting mechanism 2 is located on one side of the straightening mechanism.

[0024] One end of the coil 4 passes sequentially between two sets of straightening wheel groups 9, through the cutting mechanism 2, and is pulled by the trolley. The wire feeding mechanism 1 moves forward and backward according to the wire feeding progress of the coil 4, so that the part of the coil 4 that is discharged is always facing the gap between the two sets of straightening wheel groups 9.

[0025] The working principle of the above structure is as follows: the coil 4 is set on the drum 3 of the wire feeding mechanism 1. One end of the coil 4 is passed through the space between the two mounting plates 8 and below the cutting mechanism 2 and fixed to the clamp of the trolley. Then, the two mounting plates 8 are adjusted so that the straightening wheel sets 9 on the two mounting plates 8 abut against the two sides of the coil 4, completing the preparation work. At this time, the drive device 6 of the trolley and the wire feeding mechanism 1 is started. The trolley pulls the coil 4 to move outward. The drum 3 rotates as the coil 4 is pulled out. The wire feeding mechanism 1 moves slowly forward or backward in coordination with the displacement speed of the trolley, so that the part of the coil 4 that is pulled out is always facing the gap between the two sets of straightening wheel sets 9, avoiding a large angle between the part of the coil 4 that is pulled out and the gap between the two sets of straightening wheel sets 9, which would cause the coil 4 to be clamped flat. The coil 4 is straightened when it is pulled out and passes between the two sets of straightening wheel sets 9. When it reaches the appropriate length, it is cut by the cutting mechanism 2.

[0026] The advantages of the above structure are: it enables semi-automatic coil feeding, straightening, and cutting, saving manpower and improving processing efficiency; with the controller and corresponding control program, it can also achieve automated processing; during the straightening process, the feeding mechanism makes corresponding forward and backward displacements, which can effectively prevent the coil from forming a large angle with the straightening mechanism during the feeding process, and it is not easy to crush the coil.

[0027] In another embodiment, combined Figure 1 and Figure 2 As shown, the wire feeding mechanism 1 has two columns 10 on its frame, and the drum 3 is rotatably connected between the two columns 10.

[0028] In another embodiment, combined Figure 1 and Figure 2As shown, the driving device 6 consists of a lead screw mechanism and a servo motor. The end of the lead screw of the lead screw mechanism is rotatably connected to one end of the frame of the wire feeding mechanism 1.

[0029] In another embodiment, combined Figure 1 and Figure 2 As shown, a spring 11 is also provided between the drum 3 and the two columns 10 so that the drum 3 can make a certain degree of adaptive position adjustment.

[0030] In another embodiment, such as Figure 1 As shown, the cutting mechanism 2 includes a bracket, a cutting blade disposed at the upper end of the bracket, and a pad disposed at the lower end of the blade holder. A first hydraulic cylinder 12 is fixed on the top of the bracket. The piston rod of the first hydraulic cylinder 12 is connected to the cutting blade. When the coil 4 is pulled out to a suitable length, the cutting blade descends to cut the coil 4.

[0031] In another embodiment, the bracket is also provided with guide grooves for the corresponding cutting blade on both sides to prevent the cutting blade from deviating during the cutting process.

[0032] In another embodiment, a controller is also included, to which the trolley, servo motor and first hydraulic cylinder 12 are connected.

[0033] In another embodiment, combined Figure 1 and Figure 3 As shown, the base 7 is provided with a guide rail 13, and the bottom of the two mounting plates 8 is provided with sliders corresponding to the guide rail 13. The two mounting plates 8 are slidably connected to the guide rail 13 respectively. The front and rear ends of the mounting plates 8 are also provided with wall plates 14 respectively. The wall plates 14 are fixed with a drive mechanism 15 for driving the mounting plates 8 to move.

[0034] Optionally, the drive mechanism 15 is a screw, which is screwed onto the wall panel 14, and the inner end of the screw is connected to the mounting plate 8.

[0035] Optionally, the drive mechanism 15 is a second hydraulic cylinder, which is fixed on the wall plate 14. The piston rod of the second hydraulic cylinder passes through the wall plate 14 and is connected to the mounting plate 8. After the second hydraulic cylinder is connected to the controller, the two mounting plates 8 can be opened and closed automatically.
