Technical Field

[0001] The utility model relates to the technical field of galvanized wire drawing processing, in particular to an auxiliary straightening mechanism in the galvanized wire drawing process. Background Art

[0002] In the prior art, a straightening device for galvanized wire drawing proposed in publication number CN219401713U includes a straightening base, a straightening box provided on the straightening base, and a traction seat and a guide seat provided on both sides of the straightening box, a traction wheel provided on the traction seat, and a guide wheel provided on the guide seat. The guide wheel is rotatably mounted on the guide seat via a passive shaft, and a deceleration bar is provided on the passive shaft. A movable brake pad is provided in the guide seat and is in contact with the deceleration bar, and a brake pad pulling structure is provided in the guide seat, so that the guide wheel braking effect is achieved through the pulling structure. In the utility model, the galvanized wire is guided into the straightening box by the guide wheel, and the guide wheel is installed via the passive shaft, and a deceleration bar is provided on the passive shaft. When the galvanized wire becomes loose, the brake pad can be brought into contact with the deceleration bar, causing the guide wheel to be urgently braked for a period of time, so that the galvanized wire returns to a taut state, thereby ensuring the straightening effect.

[0003] This application can brake the guide wheel through the provided brake pads so that the galvanized wire can be restored to a taut state later. However, after long-term use, the friction of the brake pads will increase the loss, and the brake pads need to be replaced, which will result in a limited service life and reduce practicality.

[0013] In summary, the present invention has at least one of the following beneficial technical effects:

[0014] 1. This auxiliary straightening mechanism in the galvanized wire drawing process can directly drive the movable plate to perform piston motion in the cavity through the driving member during use. The polygonal column is squeezed by the rotating shaft, thereby braking the polygonal column. Because the polygonal column and the guide shaft are fixedly connected, when the polygonal column is braked, the guide shaft also achieves a braking effect, thereby reducing friction between the rotating shaft and the polygonal column. Braking is achieved only by the force of squeezing, thereby increasing the service life of the mechanism.

[0016] 3. This auxiliary straightening mechanism during the galvanized wire drawing process has an air injection portion that injects air into the vent portion. The airflow is preferentially injected into the vent ring and then into all the inserts. The air enters the corresponding cavity through the inserts, and the air pressure in the cavity increases, thereby pushing the corresponding movable plate to perform piston movement in the direction of the polygonal column, thereby facilitating braking by the rotating shaft being in contact with the polygonal column.

[0017] 4. This auxiliary straightening mechanism in the galvanized wire drawing process, when air injection is required, the push rod is rotated at this time. When the push rod is rotated, the air in the threaded tube will be pushed into several air injection tubes, and then into the ventilation ring, and finally the movable plate will be pushed to brake the guide shaft.

DETAILED DESCRIPTION

[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] Example: Refer to Figure 1-Figure 3 The utility model discloses an auxiliary straightening mechanism for the galvanized wire drawing process, comprising a guide seat 1, a through slot 2 being formed on the side of the guide seat 1, a positioning shaft 3 being rotatably connected in the through slot 2, a polygonal column 4 being rotatably connected to the positioning shaft 3, a guide shaft 5 being fixedly connected to the end of the polygonal column 4, a brake member 6 being provided on the circumferential side of the through slot 2, and a driving member 7 being provided on the surface side of the guide seat 1;

[0025] The brake member 6 includes a cavity 8, a movable plate 9, a groove 10 and a rotating shaft 11, wherein the number of the cavity 8, the movable plate 9, the groove 10 and the rotating shaft 11 corresponds to the number of sides of the polygonal column 4, the cavity 8 is opened on the inner side wall of the through groove 2, the movable plate 9 is slidably connected in the cavity 8, and the movable plate 9 is dynamically sealed in the cavity 8, the groove 10 is opened on the side of the movable plate close to the polygonal column 4, the rotating shaft 11 is rotatably installed in the groove 10, and a gap is left between the circumferential side of the rotating shaft 11 and the corresponding side of the polygonal column 4.

[0026] In this embodiment, when in use, an identical mechanism is set opposite to the mechanism, so that the galvanized wire can pass through the two guide shafts 5 in the two mechanisms and perform a guiding role. When the galvanized wire is loose and the guide shaft 5 needs to be braked, the movable plate 9 is driven by the driving member 7 to perform piston movement in the cavity 8 and move toward the direction of the polygonal column 4, so that the rotating shaft 11 in the groove 10 at the end of the polygonal column 4 gradually fits the polygonal column 4, wherein the polygonal column 4 continues to rotate, and then the polygonal column 4 will touch the rotating shaft 11 first at the side corner when rotating, wherein the continuous fit of the rotating shaft 11 increases the extrusion pressure on the outside of the polygonal column 4, and then makes The rotating shaft 11 gradually moves to fit the corresponding side of the polygonal column 4, and the corners of the polygonal column 4 will also generate an extrusion pressure on the rotating shaft 11 until the rotating shaft 11 can fit the corresponding side of the polygonal column 4. At this time, as the pressure exerted by the driving shaft 11 of the driving member 7 on the polygonal column 4 increases, it gradually slows down to achieve a braking effect. When the polygonal column 4 rotates and rubs against the rotating shaft 11, the rotating shaft 11 will rotate. The stress exerted by the rotating shaft 11 is used to brake the polygonal column 4, thereby avoiding mutual friction between the polygonal column 4 and the rotating shaft 11, allowing the rotating shaft 11 to rotate when in contact with the polygonal column 4, thereby reducing loss and increasing the service life of the rotating shaft 11 during braking.

In addition, the anti-slip protrusion 12 is arranged in an arc shape to prevent the sharp edges from scratching the rotating shaft 11, causing damage to the rotating shaft 11 and affecting the use of the rotating shaft 11.

[0029] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the driving member 7 includes an air injection part and a ventilation part, the ventilation part includes a number of cannulas 13, and several of the cannulas 13 are respectively connected to the corresponding cavities 8.

The air will enter the corresponding cavity 8 through the insert 13, and the air pressure in the cavity 8 will increase, thereby pushing the corresponding movable plate 9 to perform piston movement toward the polygonal column 4, thereby facilitating braking by fitting the polygonal column 4 through the rotating shaft 11.

[0031] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the inner circumference of the ventilation ring 14 is connected to a number of air injection pipes 15, and the air injection pipes 15 are distributed in a ring array.

[0032] In this embodiment, a plurality of air injection pipes 15 are provided and distributed in a circular array, so as to ensure uniform flow of air when injecting air into the ventilation ring 14, thereby facilitating the movement of the multiple movable plates 9.
