Description

Technical Field

[0001] The utility model relates to the technical field of low-oxygen copper rod processing, in particular to a low-oxygen copper rod processing post-traction device. Background Art

[0002] Copper rod is the main raw material of the cable industry. Among them, the copper rods with dominant usage are mainly low-oxygen copper rods produced by continuous casting and rolling and low-oxygen copper rods produced by upward continuous casting. Low-oxygen copper rods have excellent electrical conductivity and good mechanical strength and are widely used in the power, electronics, communications and other industries. In the production process of continuous casting and rolling copper rods, the finished copper rods are usually adjusted to a fixed position on the production line by traction to facilitate the continuous production of large quantities of copper rods.

[0003] The Chinese patent with publication number CN213856975U discloses a traction device for low-oxygen copper rod after processing. The device can adjust the distance through a first limit ring and a second limit ring. At the same time, the electric push rod can drive the clamping mechanism on the right to move, so as to clamp the copper rod, so as to adapt to copper rods of different models and sizes.

[0004] However, in actual use, we found that when facing the traction of some low-oxygen copper rods with smaller diameters, the limit rings of two adjacent traction wheels would offset each other at the same horizontal plane, resulting in the two traction wheels being unable to effectively clamp the low-oxygen copper rods, thus affecting the traction effect.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 5 , the present utility model discloses a traction device for low-oxygen copper rod after processing, which includes a mounting frame 1, and also includes a first traction wheel 4, and the first traction wheel 4 is fixed on the upper surface of the mounting frame 1; a second traction wheel 7, and the second traction wheel 7 is slidably installed on one side of the first traction wheel 4, and the first traction wheel 4 and the second traction wheel 7 are arranged in a staggered manner in the vertical plane. It should be noted that the staggered arrangement of the first traction wheel 4 and the second traction wheel 7 can reduce the minimum distance between the first traction wheel 4 and the second traction wheel 7, thereby facilitating the clamping and traction of a lower-oxygen copper rod with a smaller diameter.

[0024] In order to improve the clamping and traction effect of the low-oxygen copper rod and reduce the loss of the first traction wheel 4 and the second traction wheel 7 caused by the friction during the traction of the low-oxygen copper rod, the traction device for low-oxygen copper rod after processing provided in this embodiment further includes a strip-shaped column 5, and the strip-shaped column 5 is equally spaced and movably arranged at the middle position outside the first traction wheel 4 and the second traction wheel 7. Telescopic assemblies are provided inside both the first traction wheel 4 and the second traction wheel 7 to adjust the extending length of the strip-shaped column 5.

[0025] In this solution, through the setting of the telescopic component, the extending length of the strip column 5 is adjusted, so that the strip column 5 abuts against the oxygen-free copper rod, thereby improving the clamping effect of the oxygen-free copper rod and avoiding the influence of friction on the use effects of the first traction wheel 4 and the second traction wheel 7.

[0026] As Figures 1 - 4 shown, the first traction wheel 4 and the second traction wheel 7 provided in this embodiment are both composed of two limiting discs, a central column 11 and a connecting sleeve. The two limiting discs are respectively fixed at the upper and lower ends of the connecting sleeve. The central column 11 is arranged inside the connecting sleeve, and both ends of the central column 11 are fixedly connected to the limiting discs.

[0027] In this solution, since the first traction wheel 4 and the second traction wheel 7 are arranged in a staggered manner, the limiting discs on the first traction wheel 4 and the limiting discs on the second traction wheel 7 are not on the same horizontal plane, so that the minimum distance between the first traction wheel 4 and the second traction wheel 7 can be reduced, which is beneficial to the clamping and traction of thinner oxygen-free copper rods.

[0028] As Figure 4 shown, the surface of the connecting sleeve provided in this embodiment is uniformly provided with second through grooves 10. Both ends of the strip column 5 penetrate through the second through grooves 10 and are slidably connected to the second through grooves 10. Through the setting of the second through grooves 10, it is convenient for the strip column 5 to move.

[0029] As Figure 4 and Figure 5 shown, the telescopic component provided in this embodiment includes a sleeve 13 embedded inside the strip column 5 and a telescopic rod 12 fixed to the outside of the central column 11. The other end of the telescopic rod 12 is inserted into the sleeve 13 and is provided with a limiting plate. A spring 14 is installed between the limiting plate and the end of the sleeve 13 away from the telescopic rod 12.

[0030] It should be noted that when the oxygen-free copper rod is being towed, the oxygen-free copper rod will squeeze the strip column 5, causing the telescopic rod 12 to retract into the sleeve 13. At this time, the spring 14 contracts and the elastic potential energy increases, so that the strip column 5 has a tendency to extend outward, further increasing the contact effect between the strip column 5 and the oxygen-free copper rod to improve the clamping effect of the oxygen-free copper rod.

[0031] As Figures 1 - 3 shown, on the upper surface of the mounting frame 1 provided in this embodiment, a first through groove 2 is opened on one side of the first traction wheel 4. A connecting sliding seat 3 rotatably connected to one end of the second traction wheel 7 is slidably connected in the first through groove 2. A lead screw 6 is rotatably installed inside the mounting frame 1 below the first through groove 2. The lead screw 6 is threadedly connected to the connecting sliding seat 3, and one end of the lead screw 6 penetrates through the mounting frame 1 and is provided with a knob.

[0032] It should be noted that by driving the screw rod 6 to rotate through the knob, due to the threaded connection between the screw rod 6 and the connecting slide 3, the connecting slide 3 moves. Under the sliding connection between the first through groove 2 and the connecting slide 3, the connecting slide 3 slides inside the first through groove 2, thereby driving the second traction wheel 7 to move, and then the distance between the first traction wheel 4 and the second traction wheel 7 can be adjusted, which is beneficial to the traction of low-oxygen copper rods with different diameter specifications.

[0033] As Figure 2 and Figure 3 shown, to achieve the drive of the first traction wheel 4, a connecting frame 8 is fixed at one end of the screw rod 6 inside the mounting frame 1. The connecting frame 8 is rotatably connected to the screw rod 6, and a driving motor 9 is fixed on one side of the connecting frame 8. The driving motor 9 is used to drive the first traction wheel 4 to rotate.

[0034] As Figures 1 - 4 shown, the strip-shaped column 5 provided in this embodiment is a component made of rubber material, and a limiting column is provided at one end of the strip-shaped column 5 away from the central column 11. The limiting column is integrally formed with the strip-shaped column 5, and the maximum diameter of the limiting column is greater than the width of the second through groove 10 to prevent the strip-shaped column 5 from disengaging from the second through groove 10 and improve the stability of the strip-shaped column 5.

[0035] The working principle and usage process of the present utility model: When in use, rotate the knob. By driving the screw rod 6 to rotate through the knob, due to the threaded connection between the screw rod 6 and the connecting slide 3, the connecting slide 3 moves. Under the sliding connection between the first through groove 2 and the connecting slide 3, the connecting slide 3 slides inside the first through groove 2, thereby driving the second traction wheel 7 to move, and then the distance between the first traction wheel 4 and the second traction wheel 7 can be adjusted, which is beneficial to the traction of low-oxygen copper rods with different diameter specifications. When traction is applied to the low-oxygen copper rod, the low-oxygen copper rod will squeeze the strip-shaped column 5, causing the telescopic rod 12 to retract into the sleeve 13. At this time, the spring 14 contracts and the elastic potential energy increases, so that the strip-shaped column 5 has a tendency to protrude outward, further increasing the contact effect between the strip-shaped column 5 and the low-oxygen copper rod to improve the clamping effect of the low-oxygen copper rod. At this time, start the driving motor 9, and make the first traction wheel 4 rotate through the driving motor 9, thereby realizing the traction of the low-oxygen copper rod between the first traction wheel 4 and the second traction wheel 7.

[0036] It should be noted that in this article, terms such as "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the process, method, article or device including the said element.

[0037] Although the embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the appended claims and their equivalents.
