[0050] In this embodiment

[0051] The water inlet of the water pump 37 is connected to the external cooling water tank, and a water diversion pipe is connected to the bottom of the water diversion bucket 40 to lead to the wastewater tank;

[0052] Before wire drawing of the steel strand, the lubricating box 41 is already filled with enough wire drawing powder, and both U-shaped frames 52 are filled with wire drawing powder. The head of the steel strand has passed through the lowermost wire drawing die 23 and is connected to the take-up roller 13;

[0053] During wire drawing, first start Motor Five in the forward direction. Its output shaft drives the bearing shaft 47 to rotate, so that the material guiding groove 49 can be driven to rotate. After the material guiding groove 49 rotates to an inclined state, turn off Motor Five, then open the material valve, and start Motor Four. Its output shaft drives the stirring rod one 44 and the stirring rod two 45 to rotate, so that the wire drawing powder in the lubricating box 41 can be smoothly discharged and fall on the upper half of the steel strand. Immediately start the electric push rod 53 in the direction opposite to the inclination direction of the material guiding groove 49.

During the rotation process, the steel strand is continuously wire drawn and wound;

[0054] During wire drawing, turn on the water pump 37, and the cooling water will be discharged to the wire drawing die 23 through the water outlet pipe 38 to form good cooling treatment for it. The used coolant is discharged into the water diversion bucket 40 through the drain port 39 and finally discharged into the external waste water tank;

[0055] At the same time, in the process of attaching drawing powder to the steel strand, a part of the excess drawing powder discharged from the feed trough 49 will fall on the U-shaped frame 52 in the same inclination direction as the steel strand until it overflows, and the overflowed drawing powder and another part of the excess drawing powder will enter the powder receiving hopper 50, and then be discharged into the powder receiving box 55 through the guide pipe 54. In addition, in the process of moving the steel strand, the drawing powder in the U-shaped frame 52 in use will be pulled, so that in addition to the drawing powder attached to the steel strand, the drawing powder in the U-shaped frame 52 in use will be In addition to the drawing powder on the steel strand, a part of the drawing powder is gradually brought into the powder receiving hopper 50, and is also discharged into the powder receiving box 55 through the guide tube 54. The powder receiving box 55 can collect the excess drawing powder and wait for it to be poured into the lubrication box 41 for continued use. When the steel strand pulls the drawing powder in the profile frame 52, as the amount of drawing powder gradually decreases, the output shaft of the electric push rod 53 will extend adaptively, so that the drawing powder can always fit with the lower half of the steel strand and form an adhesion effect. When the drawing powder in the shaped frame 52 is almost used up, the motor 5 can be started in the reverse direction first, and the feed chute 49 starts to rotate in the reverse direction, and finally the tilting direction is changed from the previous direction to the other symmetrical direction, and then the output shaft of the previously unused electric push rod 53 is started to extend, which can drive the corresponding shaped frame 52 to rise, and finally the drawing powder in the previously unused shaped frame 52 rises to fit with the lower half of the steel strand, and then the output shaft of the previously unused electric push rod 53 is started to retract. The U-shaped frame 52 with the internal drawing powder used up is brought back to the initial position. At this time, the two U-shaped frames 52 are replaced one above the other. At the same time, due to the change in the inclination direction of the material introduction trough 49, the excess drawing powder will enter the U-shaped frame 52, so as to refill the drawing powder. After that, this reciprocating operation is repeated. By changing the inclination direction of the material introduction trough 49 and using the two U-shaped frames 52 alternately, the drawing powder is continuously fully attached to the steel strand in the drawing process.

[0056] When the amount of steel strand wound on the take-up roller 13 reaches the expected requirement, the wire drawing is stopped, and then the motor three is started in the forward direction. Through the meshing of the two gears one, the bidirectional lead screw 14 starts to rotate, so that the two joint plates 15 move away from each other, so that the corresponding clamping head 18 is separated from the take-up roller 13 with the steel strand wound. Then the take-up roller 13 is taken out from the two rotating grooves 11, and an empty take-up roller 13 is put in. Then the motor three is started in the reverse direction, and the clamping head 18 is used again to clamp the empty take-up roller 13 tightly. Then the wire end of the steel strand is connected to the take-up roller 13, and the wire drawing work can continue.

[0057] In the subsequent wire drawing process, when it is necessary to replace other wire drawing dies 23, the output shaft of cylinder 1 35 can be started to extend, and its output shaft drives the push plate 36 to descend, and finally the push plate 36 is used to push out the embedded head 33 inserted into the embedded groove 30. At this time, the bottom end surface of the push plate 36 is flush with the top end surface of the support frame 4, and then the central axis 20 is rotated. During the rotation process, whenever an embedded head 33 contacts the top inner wall of the support frame 4, it will automatically retract into the storage groove 31. The corresponding spring 2 32 is also in a compressed state, and when the embedded head 33 is separated from the top inner wall of the support frame 4, the compressed spring 2 32 releases its elastic force, and pushes the embedded head 33 out of the receiving groove 31, until the wire drawing die 23 to be used is rotated to the bottom, the output shaft of the cylinder 1 35 can be started to retract, the embedded groove 30 is opened, and then the uppermost embedded head 33 is automatically inserted into the embedded groove 30 under the action of the spring 2 32, and then the central shaft 20 is released to continue the wire drawing work;

[0058] In addition, when the wire drawing die 23 wears out after long-term use and needs to be replaced, the corresponding positioning rod 27 is directly pulled to pull it out from the corresponding positioning groove 25. At this time, the corresponding spring 29 is in a stretched state, and then the corresponding wire drawing die 23 can be directly pulled out from the die hole 22. After that, the new wire drawing die 23 is inserted into the die hole 22, and the corresponding insertion rod 24 on it is inserted into the corresponding position. Then, the positioning rod 27 is released, and the stretched spring 29 is pulled back to directly bring the positioning rod 27 back into the positioning groove 25, thereby completing the replacement of the wire drawing die 23.

[0059] Compared with the related art, the steel strand production drawing machine provided by the present invention has the following beneficial effects:

[0060] ①, by opening a slot 7 on the rotating shaft 6, and installing the mounting block 8 on the pay-off roller 9 in the slot 7 by bolts, the subsequent replacement of the pay-off roller 9 can be facilitated. At the same time, by providing two chucks 17 and a clamping head 18 provided on the chucks 17, the take-up roller 13 can be quickly replaced by rotating the bidirectional lead screw 14, so as to facilitate people's use;

[0061] ②, by setting the disc 21 and evenly setting a plurality of wire drawing dies 23 with different inner diameters on the disc 21, the wire drawing die 23 to be used can be quickly adjusted by a turntable. Compared with the traditional complicated replacement, this method is faster and improves the wire drawing efficiency. Moreover, by plugging the positioning groove 25 and the positioning rod 27, the wire drawing die 23 can be quickly replaced when the wire drawing die 23 is seriously worn.

[0062] ③. By providing a lubrication box 41 capable of discharging drawing powder from the top and a profile frame 52 for fitting the drawing powder to the steel strand from the bottom, the steel strand can be fully attached with the drawing powder, thereby avoiding dead corners for the adhesion of the drawing powder, and providing relatively comprehensive lubrication protection for the drawing die 23 and the steel strand. In the process of discharging the drawing powder, the lubrication box 41 can prevent the drawing powder from being blocked by the continuously rotating stirring rod 1 44 and stirring rod 2 45, thereby ensuring that the drawing powder can be discharged smoothly.

[0069] The same empty wire winding roller 13 is placed in the two card slots 61. And in the initial state, the output shafts of the electric telescopic rods 62 are in the extended state;

[0070] When the drawn steel strand is being wound up, the take-up roller 13 close to the drawing bench 1 is in use for winding. When it is necessary to replace the take-up roller 13 after winding is completed, the motor six can be directly started. Through the meshing of the two second gears, the first transmission rod 57 can be driven to rotate, and then the rotating bar 58 can be driven to rotate. After the positions of the two take-up units are exchanged, the motor six is turned off. At this time, the empty take-up roller 13 replaces the position of the previously used take-up roller 13, and then the end of the steel strand is fixed to this take-up roller 13 for winding.
