Technical Field

[0001] The utility model belongs to the technical field of copper rod stretching, in particular to a copper rod stretching device. Background Art

[0002] Copper rod drawing is an important metal processing technology. The purpose of copper rod drawing is usually to improve the physical properties and dimensional accuracy of the copper rod. Through drawing, the grains of the copper rod can be refined, thereby improving its strength and toughness.

[0003] For example, a Chinese patent with publication number CN218656209U discloses a copper rod stretching device, including a stretching machine, a rotating groove is provided in the front surface array of the stretching machine, sleeve perforations are provided at both the upper and lower ends of the rotating groove, an extrusion mechanism is installed inside the rotating groove, a connecting rod is installed in the outer annular array of the extrusion mechanism, an extrusion sleeve is installed at the outer end of the connecting rod, a feed hole is provided at one end of the extrusion sleeve, a discharge hole is provided at the other end of the extrusion sleeve, and a shaping hole is provided inside the extrusion sleeve between the discharge hole and the feed hole. The aperture of the feed hole is arranged in a decreasing manner at the end of the extrusion sleeve, and the aperture of the corresponding discharge hole to the feed hole with different apertures is also arranged in a decreasing manner. The extrusion mechanism inside the rotating groove arranged in the array can quickly adjust the shaping holes with different apertures to process the copper rod, so that copper rods with different diameters can be quickly processed and produced.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used. For example, when this device stretches the copper rod, due to the large friction force of the copper rod during the stretching process, the copper rod may be difficult to stretch due to the large friction force, or even get stuck. In addition, the large friction force can easily cause the connecting rod to bend, thus affecting the operation of this device. In view of this, we propose a copper rod stretching device.

At the same time, the bottom end of the sponge block 14 will absorb the copper stretching oil in the loading box 13. Then, personnel can place one end of the copper rod that needs to be stretched on the power wheel 6, and then rotate the threaded rod 15. Under the action of the thread The rotation of the threaded rod 15 will drive the sliding plate 4 to move downward, and the downward movement of the sliding plate 4 will drive the lower pressure wheel 5 and the loading box 7 to move downward until the lower pressure wheel 5 and the power wheel 6 can clamp the copper rod, and then the motor 16 can be started, and the output shaft of the motor 16 will drive the power wheel 6 to rotate, and the power wheel 6 can transport the copper rod by rotating. At the same time, under the action of friction, the copper rod will drive the lower pressure wheel 5 to rotate, and then the copper rod will pass between the sponge block 1 8 and the sponge block 2 14. At this time, the sponge block 1 8 and the sponge block 2 14 can apply copper stretching oil to the surface of the copper rod to ensure that the friction of the copper rod can be reduced during the stretching process, so that the stretching process is smoother and the energy consumption is reduced.

[0082] Then one end of the copper rod will enter into one of the feed holes 19, and then enter into the remaining feed holes 19 in turn. Since the diameter of the feed hole 19 is larger at one end and smaller at the other end, several feed holes 19 can stretch the copper rod at this time. When it is necessary to adjust the thickness of the copper rod after stretching, the personnel can first pull the pull rod 23, and the pull rod 23 will drive the limit block 22 to move in the groove 21, and squeeze the spring 24 to contract until one end of the limit block 22 moves out of the limit plate 20. At this time, the limit block 22 can release the limit on the limit plate 20, and then the personnel can pull the limit plate 20 out of the base 1. At this time, the limit plate 20 can release the limit on several extrusion sleeves 18, and then the personnel can stretch the thickness of the copper rod as needed, adjust the number of several extrusion sleeves 18, and move the large-diameter extrusion sleeve 18. To the other side of the corresponding sliding groove 17, and then the limit plate 20 is inserted back into the base 1. At the same time, the limit plate 20 will squeeze the inclined surface of the limit block 22, so that the limit block 22 moves in the groove 21, and squeeze the spring 24 to contract until one end of the limit block 22 completely enters the groove 21. When the limit plate 20 is fully inserted into the base 1, the limit plate 20 can limit the plurality of extrusion sleeves 18. At the same time, under the action of the rebound force of the spring 24, the spring 24 will squeeze the limit block 22 to move until one end of the limit block 22 is inserted into the limit plate 20. At this time, the limit block 22 can limit the limit plate 20, ensuring that it is convenient for personnel to adjust the thickness of the stretched copper rod. At the same time, the plurality of extrusion sleeves 18 are attached to each other to ensure that the extrusion sleeves 18 will not be deformed during the stretching process.
