Description

Technical Field

[0001] The utility model relates to the technical field of guiding core wires of wire feeding machines, in particular to a guiding device for the core wires of wire feeding machines. Background Art

[0002] The refining furnace needs to feed the molten steel with wire, which is mainly used for alloying and inclusion modification. The wire feeder is the main equipment for the refining furnace wire feeding process.

[0003] The existing wire feeding machine generally transports the wire into the molten steel through the guide tube by the wire feeding machine body. When feeding the wire, it is necessary to adjust the position of one end of the guide tube from the molten steel. The existing adjustment method is generally to start the hydraulic telescopic cylinder on the lower side of the hinged guide plate to make the guide plate drive the guide tube to swing up and down. However, the swing of the guide tube will cause the position of the wire output to be different, and the output position of the wire cannot be accurately adjusted. In addition, when fixing the guide tube, it is necessary to first fix the auxiliary clamping structure on the outside of the guide tube, and then fix it to the guide plate with bolts, which is more troublesome to install. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing refining furnace wire feeder cannot accurately adjust the wire output position when adjusting the wire feeding, and the installation operation of the guide tube is complicated.

[0005] In order to solve the above problems, the technical solution adopted by the present invention is a guiding device for the core wire of a wire feeding machine, including a wire feeding machine body, one side of the wire feeding machine body is a wire outlet end, and hinged platforms are fixed at both ends of the wire outlet end on both sides of the wire feeding machine body, a guide plate is hinged on one side of the hinged platform, and a connecting plate is fixed between one end of the two guide plates. A hydraulic telescopic cylinder is hinged at the two guide plates below one side of the wire feeding machine body, and the top of the hydraulic telescopic cylinder is hinged to the lower side of the guide plate. A catheter fixing structure is provided at both ends of the guide plate above the guide plate, and a sleeve-type catheter structure is sandwiched in the catheter fixing structure.

[0006] As a further solution of the present invention: the catheter fixing structure includes two arc-surface clamping shoes located above the two ends of the guide plate, and through holes are opened on the upper sides of both ends of the two arc-surface clamping shoes. A threaded hole is opened on the upper side of the guide plate at the through hole. The thread in the threaded hole is screwed tightly connected to a fastening threaded rod passing through the through hole. Rotating the fastening threaded rod can drive the arc-surface clamping shoes to clamp the inner lining pipe, so as to fix the position of the inner lining pipe.

[0007] As a further solution of the present invention: the sleeve-type catheter structure includes an inner liner tube clamped in a curved clamping shoe, an outer catheter is sleeved on the outer side of one end of the inner liner tube, and a gear rod is fixed to one side of the outer catheter.

[0008] As a further solution of the present invention: two motor frames are fixed on the lower side of the connecting plate, a transmission motor is fixed on the upper side of the motor frame, and a transmission gear that meshes with the gear rod is fixed at the output end of the transmission motor. When the transmission motor is started, the gear rod will be driven to move through the transmission gear.

[0009] As a further solution of the present invention: a square hole is opened on one side of the connecting plate at the gear rod, and the gear rod is inserted into the square hole to prevent the outer tube from swinging to both sides.

[0010] As a further solution of the present invention: one end of the outer conduit is bent downward to facilitate the output of the wire into the molten steel.

[0011] As a further solution of the present invention: the transmission motor is electrically connected to an external power supply, and the hydraulic telescopic cylinder is connected to an external hydraulic control device.

[0012] Compared with the prior art, the advantages of the present invention are as follows: 1. The present invention adds a sleeve-type conduit structure. By meshing the gear rod on one side of the outer conduit with the large gear, the transmission motor is started to drive the large gear to rotate, which can drive the gear rod to move telescopically. After the guide plate drives the sleeve-type conduit structure to swing, the position of the wire output end from the molten steel can be accurately adjusted in this way;

[0013] 2. A catheter fixing structure is added to facilitate the installation and fixing of the liner pipe, and the auxiliary installation block structure is removed. It can be directly fixed above the guide plate, which is convenient and quick to install. BRIEF DESCRIPTION OF THE DRAWINGS
