[0020] The method of using the wire pulling device is as follows:

[0021] S1: As shown in the figure, the steel wire passes through the die on the second loading rack for drawing operation, and the steel wire is pulled by an external winding device. At the same time, the thinned steel wire passes through the measuring arc plate in the detection mechanism for diameter quality detection. If the die on the second loading rack is damaged after long-term use, the diameter of the steel wire drawn by the device will become thicker than the standard diameter. Since the two measuring arc plates form a diameter detection structure for the steel wire, the thickened steel wire will exert pressure on the measuring arc plate to generate friction, so that the steel wire can drive the measuring arc plate to move;

[0022] S2: The slider is driven to move by the moving measuring arc plate, so that the slider can drive the conveying chain belt on the sprocket assembly to rotate synchronously through the storage rack, and at the same time, the force rod on the top of the slider will move along the guide groove on the horizontal plate, and the sprocket assembly will drive the power gear to rotate synchronously, and the transmission shaft of the sprocket assembly will stretch the coil spring to deform, and the rotating power gear will drive the meshing tooth plate to move, and the tooth plate will drive the locking block to slide in the outer cylinder through the transmission rod, so that the locking block is disengaged from the locking groove on the counterweight block;

[0023] S3: At this time, the counterweight block will slide downward along the inner wall of the outer cover for a certain distance under the action of its own weight, and the first loading frame and the cutter will be driven downward by the counterweight block, and the steel wire on the second loading frame will be cut off by the gates on both sides of the cutter. The counterweight block will continue to drive the first loading frame to move downward, and the trigger block on the side wall of the first loading frame will move synchronously. At this time, the trigger block will press against the force-bearing block and apply pressure, so that the force-bearing block can drive the connecting plate to move, and the connecting plate drives the guide rod and the limit block to move synchronously. The guide rod compresses the spring in the storage cylinder, and at the same time, the limit block will move away from the guide block to release the support relationship, so that the second loading frame can drive the damaged die to fall downward;

[0024] S4: Afterwards, the end of the steel wire between the measuring arc plates can continue to drive the slider to move. Since the force-bearing rod on the top of the slider is fitted in the guide groove of the horizontal plate, and one end of the guide groove is tilted outward, when the force-bearing rod moves into the inclined part of the guide groove, the force-bearing rod will drive the slider to move in the storage rack, and the slider drives the corresponding measuring arc plate to move, so that the two measuring arc plates are slightly opened to release the steel wire. The coil spring is used to drive the sprocket assembly to reset, and the worker can cut off a small amount of unqualified part of the end of the pulled steel wire;

[0025] S5: When the counterweight moves into place and contacts the top of the support shell, the first loading frame will no longer move. At this time, the new die on the first loading frame will face the wire feed port opened on the side wall of the support shell. The feed port and the discharge port on the support shell are much larger than the diameter of the wire. At the same time, the damaged die on the second loading frame will face the downward sealing cover, and the wire drawing structure can be automatically replaced, and the wire drawing process can be continued. The user can remove the damaged die on the second loading frame by opening the lower sealing cover, and the electric cylinder is used to drive the counterweight to reset.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: the drawing device for processing heat-resistant cold heading steel wire and the operating method thereof can detect the diameter of the drawn steel wire during use, thereby effectively ensuring the processing quality of the steel wire, and the device can automatically replace the damaged drawing die. The specific contents are as follows:

[0027] 1. The measuring arc plate is symmetrically distributed around the center of the steel wire, and two diameter detection structures are formed. The convex teeth on the measuring arc plate are interlocked with each other. The measuring arc plate is fixedly installed on the corresponding slider, and the slider is fitted in the slide groove on the storage rack. The side of the storage rack away from the slider is fixedly connected to the conveyor chain of the sprocket assembly. A vertically arranged force rod is fixedly connected to the upper end surface of the slider, and a horizontal plate is fitted on the top of the slider. A corresponding guide groove is opened on the horizontal plate, and a force rod is fitted on the end of the guide groove. The measuring arc plate is arranged behind the steel wire die. When the die is damaged, the steel wire with a thicker diameter drawn out will exert pressure on the measuring arc plate, so that the steel wire can drive the measuring arc plate to move through friction, thereby completing the steel wire drawing quality inspection;

[0028] 2. The second loading frame is vertically arranged directly below the first loading frame, and the middle axes of the second loading frame and the first loading frame are both slidably penetrated by a die, and a force block and a limit block are fixedly connected to the side wall of the connecting plate, and the force block and the limit block are distributed on the upper and lower sides of the guide block, and the limit block is in a right-angled triangle structure, and a guide block is fitted on the top of the limit block to form a supporting structure, and the force block is in an isosceles triangle structure, and the inclined surface of the force block is directly below the trigger block, and the trigger block is horizontally fixedly connected to the outer wall of the first loading frame, when the first loading frame moves downward, the trigger block can apply pressure to the force block, so that the force block can drive the limit block to move through the connecting plate, and the limit block no longer locks the guide block on the second loading frame, and at this time the first loading frame can push the second loading frame to move downward, so that the new die on the first loading frame can move to the working position, and the second loading frame can drive the broken die to move downward.

[0051] The method of using the wire pulling device is as follows:

[0052] S1: As shown in the figure, the steel wire passes through the die 3 on the second loading frame 6 for a drawing operation, and the steel wire is pulled by an external winding device. At the same time, the thinned steel wire passes through the measuring arc plate 2401 in the detection mechanism 24 for diameter quality detection. If the die 3 on the second loading frame 6 is damaged after long-term use, the diameter of the steel wire drawn by the device will become thicker than the standard diameter. Since the two measuring arc plates 2401 form a diameter detection structure for the steel wire, the thickened steel wire will exert pressure on the measuring arc plate 2401 to generate friction, so that the steel wire can drive the measuring arc plate 2401 to move;

[0053] S2: The movable measuring arc plate 2401 is used to drive the slider 2402 to move, so that the slider 2402 can drive the conveyor chain on the sprocket assembly 20 to rotate synchronously through the storage rack 2404, and at the same time, the force rod 2403 on the top of the slider 2402 will move along the guide groove 2406 on the horizontal plate 2405. At this time, the sprocket assembly 20 will drive the power gear 19 to rotate synchronously, and the transmission shaft of the sprocket assembly 20 will stretch the coil spring 23 to deform, and the rotating power gear 19 will drive the meshing tooth plate 17 to move, and the tooth plate 17 will drive the locking block 14 to slide in the outer cylinder 15 through the transmission rod 16, so that the locking block 14 is disengaged from the locking groove on the counterweight 12;

[0054] S3: At this time, the counterweight block 12 will slide downward along the inner wall of the outer cover 13 for a certain distance under the action of its own weight, and the counterweight block 12 will drive the first loading frame 2 and the cutting blade 4 to fall downward, and the gates on both sides of the cutting blade 4 will be used to cut off the steel wire on the second loading frame 6. The counterweight block 12 will continue to drive the first loading frame 2 to move downward, and the trigger block 5 on the side wall of the first loading frame 2 will move synchronously. At this time, the trigger block 5 will press against the force block 802 and apply pressure, so that the force block 802 can drive the connecting plate 801 to move, and the connecting plate 801 drives the guide rod 804 and the limit block 803 to move synchronously, and the guide rod 804 will compress the spring 806 in the storage tube 805, and at the same time, the limit block 803 will move away from the guide block 7 to release the support relationship, so that the second loading frame 6 can drive the damaged die 3 to fall downward;

[0055] S4: Afterwards, the end of the steel wire between the measuring arc plates 2401 can continue to drive the slider 2402 to move.

Since the two measuring arc plates (2401) form a diameter detection structure for the steel wire, the thickened steel wire will exert pressure on the measuring arc plate (2401) to generate friction, so that the steel wire can drive the measuring arc plate (2401) to move; S2: The movable measuring arc plate (2401) is used to drive the slider (2402) to move, so that the slider (2402) can drive the conveyor chain on the sprocket assembly (20) to rotate synchronously through the storage rack (2404), and at the same time, the force rod (2403) on the top of the slider (2402) will move along the guide groove (2406) on the horizontal plate (2405), and the sprocket assembly (20) will drive the power gear (19) to rotate synchronously, and the transmission shaft of the sprocket assembly (20) will stretch the coil spring (23) to deform, and the rotating power gear (19) will drive the meshing tooth plate (17) to move, and the tooth plate (17) will drive the locking block (14) to slide in the outer cylinder (15) through the transmission rod (16), so that the locking block (14) is disengaged from the locking groove on the counterweight block (12); S3: At this time, the counterweight (12) will slide downward along the inner wall of the outer cover (13) for a certain distance under the action of its own weight, and the counterweight (12) will drive the first loading frame (2) and the cutting member (4) to fall downward, and the gates on both sides of the cutting member (4) will cut off the steel wire on the second loading frame (6). The counterweight (12) will continue to drive the first loading frame (2) to move downward, and the trigger block (5) on the side wall of the first loading frame (2) will move synchronously.

Since the force-bearing rod (2403) on the top of the slider (2402) is fitted in the guide groove (2406) of the horizontal plate (2405), and one end of the guide groove (2406) is tilted outward, when the force-bearing rod (2403) moves into the tilted portion of the guide groove (2406), the force-bearing rod (2403) will drive the slider (2402) to move in the storage rack (2404), and the slider (2402) drives the corresponding measuring arc plates (2401) to move, so that the two measuring arc plates (2401) are slightly opened to release the steel wires.

S5: When the counterweight (12) moves into position and contacts the top of the support shell (1), the first loading frame (2) will no longer move. At this time, the new die (3) on the first loading frame (2) will face the wire feed port opened on the side wall of the support shell (1). The feed port and the discharge port on the support shell (1) are much larger than the diameter of the wire. At the same time, the damaged die (3) on the second loading frame (6) will face the downward sealing cover (9), and the wire drawing structure can be automatically replaced.
