Description

Technical Field

[0001] This utility model relates to a wire feeder guide tube, belonging to the technical field of wire feeder equipment. Background Technology

[0002] In steelmaking, the wire feeding process optimizes and improves the quality of molten steel. It increases the recovery rate of easily oxidized elements such as aluminum, calcium, titanium, boron, and rare earth elements, while also improving the accuracy of steel composition. Therefore, the wire feeder plays a crucial role in steelmaking. Traditional wire feeder guide tubes are simply steel pipes with a certain curvature. When aluminum wire, calcium wire, or other wires frequently pass through these tubes, severe wear occurs, significantly reducing their lifespan. Furthermore, due to the high rigidity and hardness of the wires, jamming during movement within the tube is common, disrupting normal production. Therefore, it is essential to improve existing wire feeder guide tubes to reduce friction between the wire and the tube, extend the tube's lifespan, and increase production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a wire feeder guide tube that can reduce wire friction, reduce friction between the wire and the guide tube, improve the service life of the wire feeder guide tube, and reduce the failure rate of the equipment.

[0004] The technical solution to the above technical problem is:

[0005] A wire feeder guide that reduces wire friction includes a guide body and a guide device. The guide body has a guide groove on its wall, with the groove plane below the upper surface of the wire inside the guide body's inner hole. The upper surface of the wire inside the guide body is higher than the groove plane. The guide device is mounted on the guide body outside the guide groove and consists of roller side plates, roller shafts, and rollers. The roller side plates are rectangular plates, with their lower ends welded to the outer walls of the guide body on both sides of the guide groove. The surfaces of the two roller side plates are parallel and opposite each other along the length of the guide body. The two roller side plates have opposing shaft holes on their surfaces, with both ends of the roller shaft installed in these holes. The rollers are fitted onto the roller shaft between the two roller side plates, with the rollers and roller shaft in a rotatable fit. The lower end of the rollers is opposite the upper surface of the guide groove in the guide body, and the lower end of the rollers is in a rolling fit with the outer periphery of the wire inside the guide body's inner hole.

[0006] The aforementioned wire feeder guide tube, which can reduce wire friction, has multiple guide grooves. These multiple guide grooves are evenly distributed along the length of the guide tube body. The multiple guide grooves are arranged sequentially along the highest point of the curved arc protrusion on one side of the guide tube body. Multiple guide devices are respectively installed on the guide tube body above the multiple guide grooves.

[0007] The aforementioned wire feeder guide that can reduce wire friction has a baffle at one end of the roller shaft, which is locked outside the shaft hole of the roller side plate. The other end of the roller shaft has a pin hole, which passes through the shaft hole of the roller side plate. A cotter pin is inserted into the pin hole to fix the roller shaft to the roller side plate.

[0008] The beneficial effects of this utility model are:

[0009] The present invention has multiple guiding devices installed on the conduit body outside the guiding groove, which can guide the wire in the inner hole of the conduit body; the multiple guiding devices are located on one side of the curved arc protrusion of the conduit body, which can prevent the wire in the inner hole of the conduit body from hard friction against the inner hole wall of the conduit body; the upper surface of the wire in the inner hole of the conduit body is higher than the groove plane of the guiding groove, and the roller of the guiding device can contact the wire, but will not hinder the movement of the wire.

[0010] This utility model has a simple structure and is easy to use. It can prevent the wire in the inner hole of the conduit body from hard friction against the inner hole wall of the conduit body. The original sliding friction between the wire and the inner hole of the conduit body is changed to rolling friction, which greatly reduces the friction force, reduces the wear on the inner hole of the conduit body, extends the service life of the equipment, reduces the occurrence of wire jamming failure, and improves production efficiency.

[0013] The following are marked in the diagram: 1. Conduit body; 2. Guide groove; 3. Guide device; 4. Roller side plate; 5. Roller shaft; 6. Roller; 7. Cotter pin; 8. Wire. Detailed Implementation

[0014] This utility model consists of a conduit body 1, a guide device 3, a roller side plate 4, a roller shaft 5, a roller 6, and a cotter pin 7.

[0015] As shown in the figure, a guide groove 2 is formed on the wall of the conduit body 1, and a guide device 3 is installed on the conduit body 1 outside the guide groove 2. The groove plane of the guide groove 2 is located below the upper surface of the wire 8 in the inner hole of the conduit body 1, and the upper surface of the wire 8 in the conduit body 1 is higher than the groove plane of the guide groove 2. This allows the guide device 3 installed on the conduit body 1 to contact the wire 8 in the inner hole of the conduit body 1 and guide the wire 8.

[0016] As shown in the figure, there are multiple guide grooves 2, which are evenly distributed along the length of the catheter body 1. The multiple guide grooves 2 are arranged sequentially along the highest point of the curved arc protrusion on one side of the catheter body 1. Multiple guide devices 3 are respectively installed on the catheter body 1 above the multiple guide grooves 2.

[0017] As shown in the figure, the guide device 3 consists of roller side plates 4, roller shafts 5, and rollers 6. The roller side plates 4 are rectangular plates. The lower ends of the two roller side plates 4 are welded to the outer walls of the guide body 1 on both sides of the guide groove 2. The plate surfaces of the two roller side plates 4 are parallel and opposite to each other along the length of the guide body 1. There are opposing shaft holes on the plate surfaces of the two roller side plates 4. The two ends of the roller shaft 5 are respectively installed in the shaft holes. The rollers 6 are fitted on the roller shaft 5 in the middle of the two roller side plates 4. The rollers 6 and the roller shaft 5 are in a rotatable fit. The lower end of the rollers 6 is opposite to the upper end surface of the guide groove 2 of the guide body 1. The lower end of the rollers 6 is in a rolling fit with the outer periphery of the wire 8 in the inner hole of the guide body 1.

[0018] In the above structure, the lower end of the roller 6 of the guide device 3 is opposite to the upper end face of the guide groove 2 of the guide body 1, but will not contact the upper end face of the guide groove 2. The embedding depth of the roller 6 on the guide body 1 should be set reasonably to ensure that the roller 6 can make good contact with the wires 8 such as calcium wire and aluminum wire, and to avoid the wire head being blocked due to the roller 6 being embedded too deeply during the wire feeding process.

[0019] As shown in the figure, one end of the roller shaft 5 has a baffle, which is stuck on the outside of the shaft hole of the roller side plate 4. The other end of the roller shaft 5 has a pin hole, which passes through the shaft hole of the roller side plate 4. The cotter pin 7 is inserted into the pin hole to fix the roller shaft 5 to the roller side plate 4.

[0020] In use, when the wire 8 passes through the inner hole of the conduit body 1, the roller 6 of the guide device 3 contacts the wire 8, and the sliding friction between the wire 8 and the inner hole of the conduit body 1 changes to rolling friction. This avoids hard friction between the wire 8 and the inner wall of the conduit body 1, greatly reduces friction, reduces wear on the inner hole of the conduit body 1, and does not hinder the movement of the wire 8. This extends the service life of the equipment, reduces the occurrence of wire jamming failures, and improves production efficiency.

[0021] An embodiment of this utility model is as follows:

[0022] The diameter of the catheter body 1 is 48 mm, and the inner diameter is 42 mm;

[0023] The vertical distance between the bottom surface of the guide groove 2 and the bottom surface of the inner hole of the guide tube body 1 is 20mm;

[0024] The roller side plate 4 is 40mm long, 25mm wide, and 3mm thick;

[0025] The diameter of the roller shaft 5 is 10mm and the length is 60mm;

[0026] The diameter of roller 6 is 30mm and its length is 45mm;

[0027] The diameter of wire 8 is 8mm.
