Description

Technical Field

[0001] The utility model belongs to the technical field of metal fiber production, and in particular relates to a self-cleaning metal fiber production drawing and crushing mechanism. Background Art

[0002] Metal fiber is a kind of slender fiber made of metal material. It has excellent electrical conductivity, thermal conductivity and mechanical properties and is widely used in electronics, aerospace and other fields. The production of metal fiber usually uses drawing technology. Drawing is the process of stretching metal materials through the channels of steel molds into slender and uniform fibers. During the drawing process, the metal blank is first heated to a certain temperature, and then it is fed into the channels of the steel mold. The blank is gradually stretched into slender fibers by the action of tension. The drawing process requires the control of parameters such as drawing speed and temperature to ensure the quality and shape of the fiber. However, in the production process of metal fibers, the problem of metal debris clogging the through holes is often encountered. This is because during the drawing process, the metal blank is stretched and deformed in the channels of the steel mold, generating a large amount of metal debris. These metal debris easily enter the through holes along with the fibers, causing blockage of the through holes. Utility Model Content

[0003] In order to overcome the problem that the existing metal fiber production drawing device has a large amount of debris attached during the drawing process, resulting in the accumulation of debris at the metal wire processing end, which is easy to block the holes.

[0005] Preferably, the cleaning function is achieved by spraying high-pressure airflow from a high-pressure cleaning jet nozzle inside the cold drawing box assembly to impact the debris on the drawing cone, thereby solving the problem of existing metal fiber production drawing devices in which a large amount of debris is attached during the drawing process, resulting in debris accumulation at the processing end of the metal wire, which is easy to clog the holes.

[0008] Preferably, the threaded sleeve is fixedly connected to the cold-drawn shell; a high-pressure cleaning air nozzle is provided on the inner side of the chip removal bin, and the output end of the high-pressure cleaning air nozzle is aligned with the inner side of the drawing taper. The high-pressure cleaning air nozzle on the inner side of the chip removal bin blows out a high-pressure airflow to the drawing taper, and the high-pressure airflow blows away the debris accumulated on the inner side of the drawing taper, thereby greatly improving the cleaning efficiency of the inside of the drawing taper and preventing the accumulation of debris from clogging its internal through hole.

[0009] Preferably, the straightening device assembly includes a straightening bracket, a fixed straightening roller, a lifting straightening roller, a lifting block, and a lifting screw; a fixed straightening roller is provided at the front end of the straightening bracket, and the fixed straightening roller is rotatably connected to the straightening bracket, and the fixed straightening roller and the lifting straightening roller cooperate to press the metal wire to achieve the function of pressure straightening.

[0011] Preferably, a lifting screw is provided at the upper end of the lifting block, and the lifting screw is connected to the internal thread of the lifting block through a transmission connection. The lifting screw is rotated to drive the lifting block to rise and fall in the vertical direction to realize the lifting and lowering adjustment function of the lifting and straightening roller, and the clamping and correction distance between the fixed straightening roller and the lifting and straightening roller is further realized, thereby effectively improving the convenience of adjusting the straightening force.

[0012] Beneficial effects of the utility model:

[0013] 1. The existing metal fiber production and drawing device has a problem that a large amount of debris is attached during the drawing process, which causes the accumulation of debris at the processing end of the metal wire and is easy to clog the holes. First, the metal wire is straightened between the fixed straightening roller and the lifting straightening roller of the straightening assembly, and then enters the interior of the cold drawing shell, and passes through the drawing cone and the cone sleeve in sequence.
