[0025] Furthermore, the straightening frame 410 is provided with a sliding plate, and the sliding plate is provided with a wedge block 4101. Two groups of fixed rods 411 are also provided between the first rotating disk 407 and the second rotating disk 420. The front and rear ends of the two groups of fixed rods 411 are provided with disks, which are respectively fixed on the first rotating disk 407 and the second rotating disk 420. A driving block 4111 is fixedly provided on each group of fixed rods 411; when the straightening frame moves forward and backward relative to the rotating frame, the wedge block 4101 and the driving block 4111 slide and cooperate, and the wedge block 4101 and the driving block 4111 constitute the second driving structure.

The driving block 4111 is an arc block, and the side of the arc block facing the wedge block 4101 is a plane. The inclined surface of the wedge block 4101 extends in the front-back direction. In this way, the sliding plate is squeezed by utilizing the sliding cooperation between the wedge block 4101 and the driving block 4111, and then the sliding plate drives the straightening frame 410 to slide.

[0026] Furthermore, a first spring 4103 is provided between the sliding plate and the straightening frame 410, and the first spring 4103 makes the straightening wheel 4105 elastically contact with the wire rod to avoid damage to the wire rod. The first straightening disk 409 is provided with two first slide grooves 4092, and the second straightening disk 408 is provided with two second slide grooves. The two first slide grooves 4092 are in the same straight line and extend along the radial direction of the first straightening disk 409, and the two second slide grooves are in the same straight line and extend along the radial direction of the second straightening disk 408. The first slide groove 4092 corresponds to the second slide groove front to back.

[0027] Furthermore, two limit assemblies are provided on each of the first straightening disk 409 and the second straightening disk 408, and the limit assemblies correspond to the straightening frames 410 one by one, and the limit assemblies include two limit plates 4091, and the limit plates 4091 cooperate with the straightening frames 410 to block along the sliding direction of the straightening frames 410. The limit plates 4091 can prevent the distance between the two straightening frames 410 from being too small, and ensure that the straightening wheel 4105 is pressed normally on the wire rod.

[0028] Furthermore, the first rotating disk 407 is provided with a guide cylinder 4072 facing backward, and the second rotating disk 420 is provided with a guide cylinder 4072 facing forward, and the guide cylinder 4072 is provided with a key groove 40721 extending along the front-to-back direction, and the first straightening disk 409 and the second straightening disk 408 both have a center hole, and the inner circumference of the center hole is provided with a connecting ring 4095, and the connecting ring 4095 is provided with a spline 4094, and the spline 4094 can slide forward and backward along the key groove 40721.

[0029] Furthermore, the center holes of the first straightening disk 409 and the second straightening disk 408 are both provided with annular grooves, the connecting ring 4095 is located in the annular grooves and can rotate along the annular grooves, and a torsion spring is provided between the annular grooves and the connecting ring 4095, and the torsion spring enables the straightening frame to rotate relative to the rotating frame.

[0030] Furthermore, both the front and rear ends of the rotating frame are connected with a rotating cylinder 414, and the rotating cylinder 414 at the rear of the front straightening assembly 400 is connected to the rotating cylinder 414 at the front of the rear straightening assembly 400 through a bevel gear 413. A bearing support 402 is provided outside the rotating cylinder 414, and the bearing support 402 is fixedly arranged on the frame 100.

[0031] Further, the straightening frame 410 in the straightening assembly 400 located in the front is defined as the front straightening frame, and the straightening frame 410 in the straightening assembly 400 located in the rear is defined as the rear straightening frame, and the number of straightening wheels 4105 on the front straightening frame is less than the number of straightening wheels 4105 on the rear straightening frame. Since the front straightening assembly 400 is subjected to a greater rotational force of the wire rod, this arrangement can make the rotational forces on the front straightening assembly 400 and the rear straightening assembly 400 substantially the same, so that the rotational forces can offset each other.

[0032] Furthermore, the wire rod straightening device further comprises a driving mechanism 500, which is in transmission connection with the front straightening assembly 400. The driving mechanism 500 is a driving motor, a driving wheel 401 is provided on the rotating cylinder 414 of the front straightening assembly 400, and a driving belt 600 is provided between the output end of the driving motor and the driving wheel 401.

[0033] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows: The driving motor is started and runs for a certain period of time, and the wire rod is input from the first feeding wheel 200 , and the wire rod enters the two straightening assemblies 400 in sequence, and finally extends out from the second feeding wheel 300 .

[0034] When the wire rod enters the straightening assembly 400, the wire rod rolls and rubs against the straightening wheel 4105. When the friction between the wire rod and the straightening wheel 4105 increases to a certain value, it means that the curvature of the wire rod increases. The wire rod drives the straightening frame to rotate relative to the rotating frame through the straightening frame 410, and the torsion spring is in a state of accumulation. The straightening frame rotates forward relative to the rotating frame, which causes the straightening frame to move backward relative to the rotating frame, and then the wedge block 4101 on the sliding plate of the straightening frame slides backward with the driving block 4111 on the rotating frame, so that the wedge block 4101 pushes the sliding plate to slide synchronously along the first slide groove 4092 and the second slide groove, and then the sliding plate drives the straightening frame 410 to move, and the two straightening frames 410 approach each other, so that the pressure of the straightening wheel 4105 on the straightening frame 410 on the wire rod increases, thereby strengthening the straightening force. Among them, the straightening frame moves backward relative to the rotating frame, which prolongs the straightening time of the wire rod by the straightening frame and improves the straightening effect.

[0035] When the radius of curvature of the wire rod decreases, the friction between the wire rod and the straightening wheel 4105 decreases, and the torsion spring releases the elastic force, so that the straightening frame rotates in the opposite direction relative to the rotating frame, and the straightening frame moves forward relative to the rotating frame, and then the wedge block 4101 on the sliding plate on the straightening frame slides forward and cooperates with the driving block 4111 on the rotating frame, and then the sliding plate is reset under the elastic force of the first spring 4103, and drives the straightening frame 410 to reset, and the two straightening frames 410 move away from each other, so that the pressure of the straightening wheel 4105 on the straightening frame 410 is reduced, thereby reducing the straightening force. In this way, the straightening pressure is automatically adjusted according to the different curvatures of the wire rod, and the wear of the wire rod on the straightening wheel 4105 is reduced, while the straightening effect is better. The rotational forces on the wire rod in the two synchronously counter-rotating straightening assemblies 400 are basically offset, so that the end of the wire rod in front of the first feed wheel 200 is not easy to swing, and thus will not cause injuries to personnel.

[0036] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
