[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] See also Figures 1 to 4 In the utility model, the cold heading machine feeding straightening device comprises a workbench 1, a straightening table 2 is fixedly installed on the top of the workbench 1, the bottom of the straightening table 2 passes through and extends to the bottom of the workbench 1, and a driving motor 3 arranged at equal distances is fixedly installed on the inner wall of the straightening table 2, and the output shaft of the driving motor 3 passes through and extends to the top of the straightening table 2, and a fixed straightening wheel 4 is fixedly connected to the output shaft of the driving motor 3, and a servo motor 5 is fixedly installed on the front of the straightening table 2, and the output shaft of the servo motor 5 passes through and extends to the inside of the straightening table 2, and a screw rod is fixedly connected to the output shaft of the servo motor 5, and a synchronous seat 6 is threadedly connected to the screw rod, and the synchronous seat 6 is slidably connected to the inner wall of the straightening table 2, and the top of the synchronous seat 6 is rotatably connected with evenly distributed auxiliary straightening wheels 7, and a through groove 8 is opened on the top of the straightening table 2, and the top of the auxiliary straightening wheel 7 passes through the through groove 8 and extends to the top of the straightening table 2, and a cleaning component 9 is arranged on the top of the workbench 1.

[0024] The cleaning assembly 9 includes a cleaning seat 901, which is installed on the top of the workbench 1. The bottom of the cleaning seat 901 passes through and extends to the bottom of the workbench 1. An air pump 902 is installed at the bottom of the cleaning seat 901. The air pump 902 is connected to the interior of the cleaning seat 901 through a pipeline. The interior of the cleaning seat 901 is provided with evenly distributed air holes 903.

[0025] The top of the workbench 1 is rotatably connected to two limiting wheels 13, and the two limiting wheels 13 are both located on the right side of the straightening platform 2;

[0026] The interior of the cleaning seat 901 is circular, and the inner surface of the cleaning seat 901 is smooth.

[0027] When it is necessary to straighten the wire material for the cold heading machine, the user first controls the servo motor 5 to power on. After the servo motor 5 is powered on, it drives the screw rod fixed to it to rotate synchronously, and the synchronous seat 6 threaded on the screw rod begins to move accordingly, thereby driving multiple sets of auxiliary straightening wheels 7 to move inside the through groove 8 to make it away from the fixed straightening wheel 4. Then the user controls the cleaning component 9 to operate. After the air pump 902 is powered on, suction is generated to send the external airflow into the interior of the cleaning seat 901. As the air pressure rises, the airflow begins to spray into the interior of the cleaning seat 901 through the multiple sets of air holes 903. Then the user passes one end of the wire material through the cleaning seat 901 and guides it to the bottom of the two sets of limiting wheels 13, and finally makes it on the top of the straightening table 2. Then the user controls the servo motor 5 to rotate in the opposite direction, driving multiple sets of auxiliary straightening wheels 7 to move toward the wire material until they contact and squeeze the wire material and stop. Then the user controls the drive motor 3 to be energized. After the drive motor 3 is energized, it drives the fixed straightening wheel 4 fixedly connected to it to start rotating. Since the wire material is restricted, it pushes the wire material to move to the left, and the friction between the auxiliary straightening wheel 7 and the wire material is large, the auxiliary straightening wheel 7 rotates accordingly, and the wire material on the right side continuously enters the top of the straightening table 2 and is squeezed and straightened by the fixed straightening wheel 4 and the auxiliary straightening wheel 7. During the movement, the airflow ejected from the air hole 903 will blow off the dust and impurities attached to the surface of the wire material, making the surface of the wire material smooth and entering the top of the straightening table 2 for straightening operation.

[0028] In the utility model, the servo motor 5 drives multiple groups of auxiliary straightening wheels 7 to move synchronously laterally away from the fixed straightening wheel 4, so as to facilitate the loading of the wire material, reduce the number of operating steps for personnel and improve the straightening efficiency. At the same time, a cleaning component 9 is arranged before straightening to clean the surface of the wire material, which can remove possible dirt, grease or other impurities, ensure smooth contact between the straightening wheel and the wire material, reduce friction resistance and improve the straightening effect.

[0029] See also Figure 1 and 2 , wherein: a control panel 10 is fixedly installed on the top of the workbench 1 , and the cleaning component 9 , the driving motor 3 and the servo motor 5 are all electrically connected to the control panel 10 .

[0030] In the present invention, the setting of the control panel 10 allows the user to operate the device more simply and quickly, thereby reducing the steps required for the user to operate and improving the straightening efficiency of the cold heading machine wire.

[0031] See also Figure 3 , wherein: a guide shaft 11 is fixedly connected to the interior of the straightening platform 2 , and the synchronous seat 6 is slidably connected to the guide shaft 11 .

[0032] In the present invention, the setting of the guide shaft 11 can limit the synchronous seat 6, so that the synchronous seat 6 is always located inside the straightening platform 2 to maintain stable movement in the horizontal direction, thereby maintaining stable movement of multiple sets of auxiliary straightening wheels 7.

[0033] See also Figure 4 , wherein: a dustproof filter plate 12 is installed at the bottom of the cleaning seat 901 , and the dustproof filter plate 12 is located at the bottom of the air pump 902 .

[0034] In the present invention, the dust filter plate 12 can filter the airflow entering the air pump 902, thereby preventing dust and impurities contained in the airflow from being sprayed onto the surface of the wire material and affecting its straightening.

[0035] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
