Description

Technical Field

[0001] This utility model relates to the field of steel wire processing technology, and in particular to a steel wire feeding and bearing device. Background Technology

[0002] When steel wire is wound, it is usually wound on a spool. This operation is very common in industrial production, especially in the fields of metal product processing and wire and cable manufacturing. A spool is a device used to change the direction of steel wire, cable and other wires or to take up and unwind wires. It usually consists of two parallel wheels with a certain gap between them so that the steel wire or cable can pass through and be wound on it smoothly.

[0003] When laying out wire, the I-beam is usually fitted onto the shaft. To facilitate this, the inner hole of the I-beam is larger than the diameter of the shaft. Furthermore, the wire laying is done by a wire laying robot, which does not require rotating the I-beam. Therefore, the I-beam and the shaft are not fixedly connected.

[0004] During the wire feeding process, initially, the I-beam is fully wound with wire, so it has a large weight and can be stably mounted on the shaft without wobbling. However, as the feeding operation progresses, the number of wires on the I-beam decreases, and the weight of the I-beam gradually decreases. At this point, when the feeding robot feeds the wire, the I-beam will wobble due to the traction force of the wire, making it difficult to control the tension of the wire. Sometimes, the wire will break, requiring welding after breakage, which affects efficiency. Utility Model Content

[0005] The main purpose of this utility model is to provide a wire feeding bearing device. After the I-beam is sleeved on the shaft, the positioning plane of the shaft and the contact plane of the I-beam are in contact, so that the contact between the shaft and the I-beam is a surface contact, thereby improving the stability of the shaft sleeved on the shaft and preventing the I-beam from swinging too much when the wire feeding robot removes the wire from the I-beam due to the decrease of the weight of the I-beam after the wire is fed, thus ensuring the normal feeding of the wire.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A wire feeding support device includes a shaft and an I-beam wheel. The I-beam wheel is slidably sleeved on the periphery of the shaft. A positioning plane is provided on the top of the shaft along the length direction. A contact plane matching the positioning plane is provided in the inner hole of the I-beam wheel. The positioning plane contacts the contact plane to improve the stability of the I-beam wheel sleeved on the shaft.

[0008] Furthermore, a number of elastic components are provided between the I-beam and the shaft. Each elastic component includes a positioning hole opened on the shaft, an elastic element installed in the positioning hole, and a positioning rod fixed to the top of the elastic element. The top of the positioning rod extends out of the positioning hole to contact the contact plane of the I-beam.

[0009] Furthermore, the positioning hole is formed on the positioning plane and is perpendicular to the positioning plane.

[0010] Furthermore, guide blocks are provided at both ends of the shaft.

[0011] Furthermore, pin holes are provided at both ends of the shaft, and positioning pins are inserted into the pin holes.

[0012] Furthermore, a connecting rod is fixed to the shaft, and a base plate is fixed to the bottom of the connecting rod.

[0013] Furthermore, the cross-sectional area of ​​the inner hole of the I-beam wheel is larger than the cross-sectional area of ​​the shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] After the I-beam wheel of this utility model is sleeved on the shaft, the positioning plane of the shaft and the contact plane of the I-beam wheel come into contact, thereby making the contact between the shaft and the I-beam wheel a surface contact. This improves the stability of the shaft sleeved on the shaft and prevents the I-beam wheel from swinging excessively when the wire is removed from the I-beam wheel by the wire feeding robot after the wire is fed out due to the decrease in the weight of the I-beam wheel. This ensures the normal feeding of the wire.

[0016] The positioning rod of this invention can abut against the contact plane of the I-beam wheel under the action of the elastic element, further preventing the I-beam wheel from shaking due to its own weight during the wire feeding process, and ensuring the normal wire feeding.

[0017] After the I-beam wheel of this utility model is sleeved on the shaft, the positioning pin can be inserted into the pin hole, so that the positioning pin can limit the I-beam wheel and prevent the I-beam wheel from slipping off the shaft, thereby improving safety. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-4 As shown, a wire feeding bearing device includes a shaft 4 and an I-beam wheel 3. The I-beam wheel 3 is slidably sleeved on the periphery of the shaft 4. A positioning plane 401 is provided on the top of the shaft 4 along the length direction. A contact plane 301 matching the positioning plane 401 is provided in the inner hole of the I-beam wheel 3. The positioning plane 401 contacts the contact plane 301 to improve the stability of the I-beam wheel 3 sleeved on the shaft 4. A connecting rod 2 is also fixed on the shaft 4, and a base plate 1 is fixed at the bottom of the connecting rod 2.

[0025] In this embodiment, such as Figure 2 As shown, the cross-sectional area of ​​the inner hole of the I-beam 3 is larger than that of the cross-sectional area of ​​the shaft 4, so the I-beam 3 can be easily fitted onto the outer periphery of the shaft 4. At this time, the positioning plane 401 of the shaft 4 and the contact plane 301 of the I-beam 3 are in contact, so that the contact between the shaft 4 and the I-beam 3 is a surface contact, thereby improving the stability of the shaft 4 fitted onto the shaft 4. This prevents the steel wire on the I-beam 3 from swinging significantly when the wire feeding robot removes the wire from the I-beam 3 due to the decrease in the weight of the I-beam 3 after the wire is fed out, which would affect the normal wire feeding.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, several sets of elastic components 6 are provided between the I-beam wheel 3 and the shaft 4. The elastic component 6 includes a positioning hole 601 opened on the shaft 4. An elastic element 602 is installed in the positioning hole 601. A positioning rod 603 is fixed to the top of the elastic element 602. The top of the positioning rod 603 extends out of the positioning hole 601 to contact the contact plane 301 of the I-beam wheel 3. The elastic element 602 is a cylindrical spring. The positioning hole 601 is opened on the positioning plane 401 and is perpendicular to the positioning plane 401.

[0027] After the I-beam 3 is fitted onto the shaft 4, the elastic element 602 will be pressed down and retracted by the weight of the I-beam 3. As the wire feeding operation proceeds, the weight of the I-beam 3 decreases, so the downward force it exerts on the positioning rod 603 gradually decreases. Therefore, the deformation of the elastic element 602 decreases, thereby exerting a reaction force on the positioning rod 603, so that the positioning rod 603 abuts against the contact plane 301 of the I-beam 3, further preventing the I-beam 3 from shaking due to the decrease in its own weight during the wire feeding process, and ensuring the normal wire feeding.

[0028] The positioning rod 603 normally extends out of the positioning hole 601. Therefore, when installing the I-beam wheel 3, a robotic arm is needed to press the positioning rod 603 so that it is fully inserted into the positioning hole 601. Then, another robotic arm is used to put the I-beam wheel 3 with the wire wound on it onto the shaft body 4, thereby avoiding the positioning rod 603 from affecting the I-beam wheel 3 being put onto the shaft body 4.

[0029] like Figure 1 As shown, guide blocks 402 are provided at both ends of the shaft 4. The guide blocks 402 are frustum-shaped, and their ends are smaller than the inner hole of the I-beam wheel 3. Therefore, the I-beam wheel 3 can be easily fitted onto the shaft 4 through the guide blocks 402.

[0030] like Figure 1 and Figure 3 As shown, pin holes 7 are also provided at both ends of the shaft body 4, and positioning pins 5 are inserted into the pin holes 7. When the I-beam wheel 3 is sleeved on the shaft body 4, the personnel can insert the positioning pins 5 into the pin holes 7, so that the positioning pins 5 can limit the I-beam wheel 3 and prevent the I-beam wheel 3 from slipping off the shaft body 4, thereby improving safety.

[0031] Working principle: First, a robotic arm presses the positioning rod 603, allowing it to fully enter the positioning hole 601. Then, another robotic arm uses to place the I-beam spool 3, with the steel wire wound on it, onto the shaft 4. At this time, the positioning rod 603 will retract due to the elastic element 602 being pressed down by the weight of the I-beam spool 3, thus bringing the positioning plane 401 of the shaft 4 into contact with the contact plane 301 of the I-beam spool 3. This results in surface contact between the shaft 4 and the I-beam spool 3, improving the stability of the shaft 4 when it is placed on the shaft 4 and preventing the steel wire on the I-beam spool 3 from slipping after being released. The decrease in weight causes the wire feeding robot to swing significantly when removing the wire from the I-beam 3, thus affecting the normal wire feeding. Furthermore, as the wire feeding operation progresses, the weight of the I-beam 3 decreases, so the downward force it exerts on the positioning rod 603 gradually decreases. Consequently, the deformation of the elastic element 602 decreases, thereby applying a reaction force to the positioning rod 603. This causes the positioning rod 603 to abut against the contact plane 301 of the I-beam 3, further preventing the I-beam 3 from shaking due to the decrease in weight during the wire feeding process and ensuring the normal wire feeding.
