Description

Technical Field

[0001] This utility model relates to the technical field of enameled wire processing equipment, and in particular to an adjustable square enameled wire rolling device. Background Technology

[0002] Enamelled wire, as the core conductor of electromagnetic coils, can be divided into round wire and flat wire according to its cross-section. Among them, square and small-radius enamelled flat wires are increasingly in demand due to their high slot fill factor in the miniaturization and high efficiency of motors. These types of enamelled wires need to meet stringent requirements such as an aspect ratio ≤1.2 and precise radius of curvature, but existing rolling technologies have significant drawbacks: Traditional square enameled wire rolling equipment only has unidirectional rolling capability. The copper wire is compressed only in the vertical direction, and the horizontal deformation depends on the subsequent drawing die. This results in insufficient material flow at the rounded corners, easily leading to problems such as incomplete rounded corners and poor shape accuracy. To compensate for this deficiency, the industry usually adopts a solution of "multi-stage drawing die" or "extrusion preforming + drawing". This not only results in high equipment investment and mold costs, but also means that a single device cannot be adapted to the production of enameled wires of multiple specifications, resulting in poor versatility.

[0003] For example, Chinese invention patent CN110280618A discloses an integrated device for the feeding, straightening and forming of flat enameled wire. Although it achieves tension adjustment and integrated production, it only addresses the design of the extrusion rollers in the forming process and does not involve precise control of the radius (R) angle and bidirectional deformation adjustment during the rolling process. Therefore, it cannot solve the problems of bidirectional deformation and R angle fullness in the rolling stage.

[0004] Therefore, there is an urgent need for a square enameled wire rolling device that can achieve bidirectional adjustable rolling, adapt to multiple specifications, and reduce mold dependence, in order to break through the existing technical bottlenecks. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable square enameled wire rolling device to solve the problems mentioned in the background art.

[0006] The above-mentioned objective of this utility model is achieved through the following technical solution: an adjustable square enameled wire rolling device, comprising: The mounting base has cross-shaped mounting holes. Adjustable rolling wheels are distributed vertically and horizontally within the mounting holes, and rectangular rolling holes are formed between the four adjustable rolling wheels; A bidirectional adjustment assembly is connected between the mounting base and the adjustable rolling roller, used to adjust the position of the adjustable rolling roller in the horizontal and vertical directions.

[0007] Preferably, the bidirectional adjustment component includes: The first screw is arranged in a square shape, and the four adjustable rolling wheels are respectively installed on the four first screws; The second screw is mounted on the mounting base. The end of the second screw is provided with a connecting end. The two ends of the first screw are respectively connected between the connecting ends of the front and rear second screws. At least one end of the first screw passes through the connecting end and is fixed by the first locking nut.

[0008] Preferably, the adjustable rolling wheel is sleeved on the first screw, and a second locking nut is provided on each side of the adjustable rolling wheel.

[0009] Preferably, the adjustable rolling wheel has an annular rolled edge protruding from the wheel surface at its center.

[0010] Preferably, the second screw includes one fixed screw and three movable screws, which are rectangularly distributed on the outside of the mounting hole, and four first screws are connected end to end between the fixed screw and the three movable screws.

[0011] Preferably, the mounting base is provided with a fixing hole and an adjusting hole, the fixing screw passes through the fixing hole, the three movable screws pass through the three adjusting holes respectively, and the end of the second screw is provided with a third locking nut.

[0012] Preferably, the adjustment hole includes a transverse elongated hole on the transverse side of the fixed hole, a vertical elongated hole on the vertical side of the fixed hole, and a large movable hole located diagonally opposite the fixed hole.

[0013] The beneficial effects of this utility model are: 1. This utility model uses a four-axis adjustable rolling wheel with a square-shaped layout to simultaneously pre-deform the copper wire in the vertical and horizontal directions, ensuring that the R-angle is fully formed and avoiding defects in the subsequent wire drawing process; 2. This device has an adjustable structure, strong versatility, and is suitable for enameled wire products with different aspect ratios. The pre-deformation reduction rate before entering the flat die is controlled between 20% and 30%, ensuring that the copper wire has good plastic deformation ability during the drawing process and avoiding material cracking or breakage.

Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0017] Example: like Figure 1-3 As shown, an adjustable square enameled wire rolling device includes: a mounting base 1, an adjustable rolling wheel 2, and a bidirectional adjustment component 3. The mounting base 1 is provided with a cross-shaped mounting hole 101, which penetrates the front and rear end faces of the mounting base 1.

[0018] There are four adjustable rolling rollers 2, which are distributed vertically and horizontally within the mounting holes 101, forming a rectangular rolling hole 4 between the four adjustable rolling rollers 2. An annular rolling edge 201 protruding from the wheel surface is provided in the middle of the adjustable rolling roller 2.

[0019] The bidirectional adjustment assembly 3 is connected between the mounting base 1 and the adjustable rolling rollers 2, and is used to adjust the horizontal and vertical positions of each adjustable rolling roller 2.

[0020] like Figure 3 As shown, the bidirectional adjustment assembly 3 includes a first screw 301 and a second screw 302. The first screw 301 is arranged in a U-shape, and four adjustable rollers 2 are respectively installed on the four first screws 301.

[0021] In this embodiment, the adjustable rolling wheel 2 is sleeved on the first screw 301, allowing the adjustable rolling wheel 2 to move freely in the axial direction of the first screw 301 to adjust the position of the adjustable rolling wheel 2. At the same time, a second locking nut 305 is provided on both sides of the adjustable rolling wheel 2. The second locking nut 305 is screwed onto the first screw 301, and the axial position of the adjustable rolling wheel 2 is fixed by the two second locking nuts 305.

[0022] The second screw 302 is mounted on the mounting base 1, and a connecting end 303 is provided at the end of the second screw 302. The connecting end 303 is integrally connected to the second screw 302. The two ends of the first screw 301 are respectively connected between the connecting ends 303 of the two second screws 302. At least one end of the first screw 301 passes through the connecting end 303 and is fixed by the first locking nut 304.

[0023] In this embodiment, one end of the first screw 301 is fixedly connected to the connecting end 303 at that end, and the other end is movably inserted into the connecting end 303 at the corresponding end and fixed by two first locking nuts 304. The two first locking nuts 304 are screwed onto the first screw 301.

[0024] Specifically, the second screw 302 includes one fixed screw 302a and three movable screws 302b. The fixed screw 302a and the three movable screws 302b are rectangularly distributed on the outside of the mounting hole 101. The four first screws 301 are connected end to end between the fixed screw 302a and the three movable screws 302b.

[0025] Mounting base 1 is provided with a fixing hole 102 and an adjustment hole. A fixing screw 302a passes through the fixing hole 102, the diameter of which matches the diameter of the screw 302a. Three movable screws 302b pass through the three adjustment holes, allowing each screw to move within a certain range in its respective direction. A third locking nut 306 is screwed to the end of the second screw 302. During installation, the connecting end 303 rests against the front face of mounting base 1, and the third locking nut 306 rests against the rear face of mounting base 1, thereby fixing the second screw 302. A washer can be installed between the third locking nut 306 and the rear face of mounting base 1.

[0026] Specifically, such as Figure 4 As shown, the adjustment hole includes a transverse elongated hole 103 located on the transverse side of the fixed hole 102, a vertical elongated hole 104 located on the vertical side of the fixed hole 102, and a large movable hole 105 located diagonally opposite the fixed hole 102. Specifically, the movable screw 302b located above the fixed screw 302a passes through the vertical elongated hole 104, the movable screw 302b located to the left of the fixed screw 302a passes through the transverse elongated hole 103, and the movable screw 302b located diagonally opposite the fixed screw 302a passes through the large movable hole 105.

[0027] The widths of the transverse elongated hole 103 and the vertical elongated hole 104 are adapted to the diameter of the movable screw 302b, and the diameter of the movable large hole 105 is larger than the diameter of the movable screw 302b, so that the movable screw 302b located in the transverse elongated hole 103 can move in the transverse direction, the movable screw 302b located in the vertical elongated hole 104 can move in the vertical direction, and the movable screw 302b located in the movable large hole 105 can move in both the vertical and transverse directions.

[0028] To facilitate intuitive observation of the movement of the movable screw 302b, scale lines in the horizontal and vertical directions are provided on the end face of the mounting base 1 at each adjustment hole.

[0029] During adjustment, loosen all the locking nuts on the front of the mounting base 1 and the third locking nut 306 on the three moving screws 302b on the back. According to the size of the design transition line gauge, adjust the screws of the three adjustable holes on the back to the target scale and then tighten the third locking nut 306. After adjusting the relative position of the adjustable roller 2, tighten all the locking nuts on the front to complete the adjustment.
