Description

Technical Field

[0001] The utility model relates to a production device of electromagnetic wire, in particular to a precision calender for electromagnetic wire production. Background Art

[0002] Electromagnetic wire is an insulated wire used to manufacture coils or windings in electrical products. The common electromagnetic wire has a circular structure. It is formed by drawing raw materials through a wire drawing machine once or multiple times. After being stretched by a circular die in the wire drawing machine, a wire of corresponding specifications is formed, and an impregnated coating is made on its outer surface.

[0003] The technology of round wire has experienced a development process of over a hundred years. Currently, it is the electromagnetic wire with the largest output and the widest application. However, after the whole wire is wound into a coil, there will be a stroke gap, and the utilization rate of space does not reach the maximum. Therefore, improving the conversion rate of motor efficiency has become one of the research hotspots in the industry. Against this background, the technology of flat wire has received extensive attention.

[0004] The production of flat wire is prepared through a calender. During the process of the calender preparing flat wire, the condition of the original wire will affect the quality of the final product. In order to ensure the quality of the wire product, multiple procedures are required to process the wire to meet the expectations. Summary of the Invention

[0008] The horizontal calendering part includes two horizontal rollers arranged opposite to each other up and down, and the horizontal rollers are arranged horizontally; the end of the roller shaft of the horizontal roller is provided with meshing gears; the roller shaft of the horizontal roller is also provided with a belt pulley; the vertical calendering part includes two vertical rollers arranged opposite to each other vertically, the end of the roller shaft of the vertical roller is provided with meshing gears, and the roller shaft of the vertical roller is also provided with a belt pulley; the belt pulleys on the horizontal roller and the vertical roller are respectively driven by motors.

[0009] The vertical roller mentioned above is of a split structure, which includes a column and a roller disc arranged on the column. The column and the roller shaft of the vertical roller are of an integral structure. The column is provided with vertically distributed sliding grooves evenly. The roller disc is of an annular structure and is installed outside the column and slides up and down on the outside of the column. The roller disc is provided with protrusions corresponding to the sliding grooves, and the cooperation between the protrusions and the sliding grooves enables the roller disc to rotate together with the column.

[0010] Furthermore, there are several groups of roller discs on the column that are arranged in pairs opposite to each other. A ring-shaped notch groove is provided at the center of the roller disc. The column is provided with pin holes, and movable plug-in type limit pins are arranged in the pin holes. The limit pins support the bottom of the roller disc, so that the notch groove at the center of the roller disc is horizontally corresponding to the center between the two horizontal rollers.

[0011] The pretreatment part mentioned above includes a rotating frame arranged on the frame. Several evenly distributed pressing rollers are arranged in the rotating frame. The pressing rollers and the rotating frame are both arranged longitudinally. When the raw material wire passes through the pretreatment part, the pressing rollers press around the raw material wire.

[0012] Two opposite annular brackets are arranged in the frame. The center of the annular brackets and the center point between the two horizontal rollers are located on the same horizontal plane. The rotating frame is of a cylindrical structure and is installed in the annular brackets. A driving motor for driving the rotating frame is arranged at the bottom of the frame, and the driving motor drives the rotating frame through a belt.

[0013] Several groups of evenly distributed support arms are hinged in the rotating frame. The number of support arms corresponds to that of the pressing rollers. The pressing rollers are arranged at the free ends of the support arms. Tensile springs are also arranged on the support arms, and the tensile springs pull the support arms to make the pressing rollers at their ends tend to the center of the rotating frame.

[0014] Furthermore, the end of the support arm is provided with a curved arc part, and the pressing roller is installed at the front end of the arc part.

[0015] Furthermore, a horn-shaped wire collecting port is also arranged at the front of the frame, and the wire collecting port corresponds to the center of the rotating frame.

[0016] The utility model adopts the above technical solutions and has the following beneficial effects:

[0017] Before the device performs calendering treatment on the metal raw material, it is first pretreated by the pressing rollers in the pretreatment part. After the raw material wire is surrounded and pressed, its surface tends to be flat and smooth, so that there will be no phenomenon of excessive overflow on the side of the wire during the calendering treatment. The combination of the horizontal rollers and the vertical rollers enables fine calendering treatment on all four sides of the flat wire.

[0018] In addition, the vertical roller adopts the form of combining the column and the roller disc, and different groups of roller discs can be selected according to the requirements of the wire during actual use, which has better applicability. Description of the Drawings
