Description

Technical Field

[0001] The invention relates to the technical field of cored wire production and processing, and in particular to a pulling processing device for a rare earth calcium-based composite cored wire. Background Art

[0002] It is made of alloy powder wrapped by strip-shaped steel strip. According to the different alloy powders, it can be divided into: silicon calcium cored wire, silicon manganese calcium wire, silicon calcium barium wire, barium aluminum wire, aluminum calcium wire, calcium iron wire, pure calcium wire and rare earth calcium wire, etc. In the production process of cored wire, the wire feeder pulls the steel strip into the wire feeder, and then the steel strip wraps the rare earth calcium powder through the wire feeder to become cored wire. After the cored wire is cooled through the process, it is finally wound by the rotation of the winding machine. At the same time, it is necessary to manually straighten the cored wire on the winding machine to improve the winding effect; for this reason, people have designed a traction device to allow the cored wire to be wound back and forth on the winding drum, so that the cored wire is evenly wound on the winding drum.

[0003] Although the above technology achieves the technical effect of evenly winding the cored wire on the take-up drum, it is only applicable to cored wire of one diameter. Once the diameter of the cored wire becomes smaller, gaps will appear between the cored wires in the same circle; if the diameter of the cored wire becomes larger, one or two cored wires will be wound in the outer circle before the inner circle is completely wound, which will ultimately shorten the length of the cored wire that can be wound on the entire take-up drum.

[0008] Preferably, the outer peripheral surface of the guide wheel has an annular groove matching the diameter of the cored wire, and the annular grooves on the two guide wheels cooperate to allow the cored wire to be rolled and connected, and to drive the cored wire to move laterally.

Two rollers 13 are rotatably installed on the mounting frame 1, and the outer peripheral surfaces of the two rollers 13 are both in contact with the outer peripheral surface of the winding drum 3. The winding drum 3 is located at the top between the two rollers 13. A motor 14 is installed on one side of the mounting frame 1, and a third pulley 15 is fixedly installed on the end of the output shaft of the motor 14. The third pulley 15 and the first pulley 9 are jointly installed with a second transmission belt 16. The second transmission belt 16 is set as a gear belt. The gear belt makes the first pulley 9 and the third pulley 15 rotate synchronously when rotating without slipping; The operator moves the empty winding drum 3 onto the roller shaft 2, and then twists the tightening member 12 to fix the winding drum 3 on the roller shaft 2. At this time, the two rollers 13 at the bottom of the winding drum 3 provide support for the winding drum 3. When the winding drum 3 rotates, the rollers 13 will also rotate; The operator needs to first know the diameter of the cored wire during this winding, and then determine the required speed ratio between the two-way return threaded rod 4 and the roller shaft 2, and adjust it with the speed change assembly 10 to ensure that when the roller shaft 2 rotates one circle, the two-way return threaded rod 4 rotates a predetermined number of circles, so that the connecting piece 6 has a predetermined distance, and then remove the top cover 8f, take out the bearing seat 8d and the corresponding guide wheel 8c, select the guide wheel 8c with the annular groove 11 matching the cored wire diameter, and then put the guide wheel 8c with the bearing seat 8d back into the vertical slide groove 8b, and then reinstall the top cover 8f on the U-shaped plate 8a, and then pass the cored wire between the two guide wheels 8c and locate it in the annular groove 11. During this period, if Figure 7 and Figure 8 As shown, when the diameter of the cored wire changes, the size of the annular groove on the guide wheel 8c needs to keep changing synchronously, so that the central axis of the cored wire is always located in the middle of the two guide wheels 8c, that is, passing through the center of the circle formed by the grooves on the two guide wheels 8c; Then the operator starts the motor 14, the motor 14 drives the third pulley 15 to rotate, the third pulley 15 drives the first pulley 9 to rotate through the second transmission belt 16, the first pulley 9 drives the roller 2 to rotate, the roller 2 will drive the winding drum 3 to rotate, so that the cored wire is gradually wound on the winding drum 3, and the first pulley 9 will also drive the third cone 10d to rotate through the first cone 10b, the third cone 10d drives another third cone 10d to rotate through the pulley transmission structure 10k commonly used in the prior art, the other third cone 10d drives the second cone 10c to rotate, the second cone 10c then drives the two-way return threaded rod 4 to rotate, the two-way return threaded rod 4 will drive the transmission member 5 to move laterally through the thread groove on the surface, when the transmission member 5 moves to the end of the thread groove and then moves in the opposite direction, thus forming a reciprocating cycle. The transmission member 5 will drive the connecting member 6 to slide on the limiting rod 7, and the limiting rod 7 will limit the connecting member 6 to move horizontally. At the same time, the connecting member 6 will drive the U-shaped plate 8a to move, and the U-shaped plate 8a will synchronously drive the bearing seat 8d, and the bearing seat 8d will drive the guide wheel 8c, and the guide wheel 8c will drive the cored wire to move horizontally through the annular groove 11. Finally, with the rotation of the roller shaft 2, the cored wire will be evenly wound back and forth on the winding drum 3, and the cored wires of the same layer wound on the winding drum 3 will fit each other to ensure that there is no gap between the cored wires. At the same time, there will be no problem that the inner layer has not been wound up yet, and the outer layer has started to wind several circles, which will eventually lead to a large gap between the adjacent upper and lower layers. When adjusting the rotation speed between the roller shaft 2 and the two-way return threaded rod 4, it is only necessary to turn the knob 10j, and the knob 10j will drive the adjusting threaded rod 10i to rotate. Because the adjusting threaded rod 10i is threadedly connected to the fixing frame 10a, the adjusting threaded rod 10i will move on the fixing frame 10a, thereby driving the limit member 10h to move, and the limit member 10h will pull the positioning rod 10e to move on the guide rail 10g, and the positioning rod 10e will drive the two third cones 10d to move, so that the transmission position of the third cone 10d and the first cone 10b and the second cone 10c changes, that is, the axial position of the third cone 10d and the first cone 10b and the second cone 10c is different, so that for every rotation of the first cone 10b, the number of rotations of the second cone 10c will change, thereby adjusting the rotation speed between the roller shaft 2 and the two-way return threaded rod 4.

Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, colors, changes in orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
