[0039] When adjusting:

[0040] The first motor 24 drives the gear 26 to rotate through the transmission rod 25, when the gear 26 rotates, the toothed plate 23 is driven to move up and down through the meshing of the gear teeth, and the clockwise rotation is downward movement, and the counterclockwise rotation is upward movement, the toothed plate 23 moves synchronously to drive the connecting plate 27 and the internal part structure of the ultrasonic mechanism 3 connected to the top to move together, so as to adapt to tracks of different thicknesses, and at the same time, adaptive stress regulation is achieved.

[0041] As shown in Figure 5 and 9 , the ultrasonic mechanism 3 comprises a transmitting assembly and a replacement assembly, the transmitting assembly is arranged on the top of the straightening box 1, and the replacement assembly is arranged on one end of the straightening box 1.

[0042] The transmitting assembly comprises an ultrasonic wave generator 31, a connecting line 32 and a probe 33, the ultrasonic wave generator 31 is installed on the top of the straightening box 1, the connecting line 32 is connected to one end of the ultrasonic wave generator 31, and the probe 33 is connected to the end of the connecting line 32 away from the ultrasonic wave generator 31.

The bracket 37 is used to reinforce the connection of the connecting strip 36. The mounting port 39 assists in the installation and disassembly of the probe group 38. The probe group 38 can be installed by bolts.

[0047] When using ultrasound to modulate stress:

[0048] First, the probe group 38 will contact the track, and then the ultrasonic generator 31 will work. Then, the connecting probe 33, together with the first connector 34 and the second connector 35, will complete the transmission of ultrasonic waves. The transducer will reciprocate in the longitudinal direction. The frequency of the reciprocating motion is equal to the frequency of the AC current of the driving power supply. The displacement of the reciprocating motion is about ten micrometers. This is used to regulate or eliminate the stress inside the track.

[0049] like Figure 5 , 7 As shown in Figure 8, the push-pull mechanism 4 includes a fixed frame 41, a carrier plate 42, an electric push rod 43, a first mounting plate 44, and a second mounting plate 45. The fixed frame 41 is installed on both sides of one end of the connecting plate 27, the carrier plate 42 is installed on the end of the fixed frame 41 away from the connecting plate 27, the electric push rod 43 is installed on the top of the carrier plate 42, the first mounting plate 44 is installed on the output end of the electric push rod 43, and the second mounting plate 45 is bolted to the side of the first mounting plate 44 away from the electric push rod 43. The second mounting plate 45 is fixed to one side of the probe 33.

[0050] The electric push rod 43 adjusts the left and right positions of the probe 33 and the bottom connected one group or two groups and three groups of probe groups 38 during pushing, so as to ensure that it can be located at the top of the track and can contact the track. The fixing frame 41 and the carrier plate 42 are mainly used to support and install the electric push rod 43. The first mounting plate 44 and the second mounting plate 45 are used to connect the probe 33 and are bolted for disassembly and assembly.

[0051] When the electric adjustment is performed:

[0052] The electric push rod 43 works according to the required pushing or pulling effect. When pushing, the electric push rod 43 drives the probe 33 to move to the left through the bolted first mounting plate 44 and the second mounting plate 45. Conversely, when pulling, it moves to the right. At this time, the screw rod 52 and the screw sleeve 53 are loose, and the screw sleeve 53 is not tightly connected with the connecting plate 27. At this time, the probe 33 is adjusted at the position of the connecting plate 27, and the first connecting head 34 slides in the adaptive opening at the top of the connecting plate 27, so as to complete the left and right position adjustment.

[0053] As shown in Figure 1 and 5 , the manual displacement mechanism 5 includes a connecting block 51, a screw rod 52, a screw sleeve 53, a pointer 54, and a through opening 55.

The screw sleeve 53 is threaded at the bottom end of the screw rod 52. The pointer 54 is installed on the surface of the probe 33. The through opening 55 is opened on one side of the top of the connecting plate 27.

[0054] The connecting block 51 facilitates threaded connection of the screw rod 52 and achieves the effect of a gasket. When the screw rod 52 and the screw sleeve 53 are tightly connected with the connecting plate 27, the position locking during manual position adjustment is realized. The pointer 54 cooperates with the engraved scale to achieve the effect of manual precise control. The through opening 55 facilitates the screw rod 52 to penetrate the connecting plate 27 and assists in left and right adjustment.

[0055] The top of the connecting plate 27 is engraved with a scale. The tip of the pointer 54 corresponds to the scale. The screw rod 52 penetrates the connecting plate 27 through the through opening 55, which is used to improve the accuracy during manual adjustment.

[0056] When the manual adjustment is performed:

[0057] The bolt between the first mounting plate 44 and the second mounting plate 45 needs to be contacted first, and then the probe 33 is directly pulled to the left or the right according to the requirement, and the lower part is moved together with the probe 33, and the accuracy of the adjustment is improved according to the scale line pointed by the pointer 54, at this time, when the preset position is reached, the movement is stopped, then the screw rod 52 and the screw sleeve 53 are tightly connected, and the screw sleeve 53 is continuously rotated to move upwards on the surface of the screw rod 52 until it contacts the bottom of the connecting plate 27, and then it is continuously rotated until it is locked by being tightly fastened on the bottom of the connecting plate 27.

[0058] As shown in Figure 4 The straightening mechanism 6 includes a driving wheel 61, a second motor 62, a driven wheel 63, a belt 64 and a lower roller 65.

[0059] The second motor 62 cooperates with the driving wheel 61, the driven wheel 63, the belt 64 and the lower roller 65 to realize the conveying of the material during straightening, and the upper roller plays a role in pressing the track, and the upper roller does not need to be driven, but only needs to be pressed with the lower roller 65 to realize the straightening of the track by rotating according to the friction force during conveying.

[0060] During straightening:

[0061] The structure for adjusting the height of the upper roller is installed in the auxiliary box 8, and the height position of the upper roller is adjusted according to the thickness of the track, until the pressure on the track is formed by the cooperation of the upper roller and the lower roller 65, and then the straightening operation is performed. At this time, the driving wheel 61 is driven to rotate by the second motor 62, the driven wheel 63 is driven to rotate by the belt 64, and the lower roller 65 is driven to rotate by the driven wheel 63, so that the straightening of the track is completed and the conveying is also formed. Due to the friction, the upper roller also rotates together with the track during conveying, so as to achieve the purpose of straightening.

[0062] As shown in Figure 1 , 2 , 3 and 4, the feeding and discharging mechanism 7 includes a first connecting frame 71, a feeding roller 72, a second connecting frame 73 and a discharging roller 74.

[0064] When feeding and discharging:

[0065] The track is first placed on the top of the feeding roller 72, and then the track is pushed to the feeding port, and after the straightening and stress regulation, the track is located on the top of the discharging roller 74, and then the discharging operation is completed.

[0066] The working process is as follows:

[0067] The track is first placed on the top of the feeding roller 72, and then the track is pushed to the feeding port, and after the straightening and stress regulation, the track is located on the top of the discharging roller 74, and then the discharging operation is completed.

[0068] During the stress regulation, the left and right positions of the probe group 38 can be adjusted by the push-pull mechanism 4 or the manual displacement mechanism 5, so that the probe group 38 is located on the top of the track, and the push-pull mechanism 4 is electrically controlled, and when a fault occurs, the manual displacement mechanism 5 is used for emergency adjustment, and when the push-pull mechanism 4 is normally working, the manual displacement mechanism 5 is in an unlocked state, and when the manual displacement mechanism 5 is working, the bolt between the push-pull mechanism 4 and the ultrasonic mechanism 3 is contacted, so that either one of them is not affected by the other one when working.
