Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of coil wire feeding, and more specifically relates to a coil wire feeding machine that is scratch-free. Background Art
[0002] A coil feeder is provided on the wire feeding end of the wire drawing machine, which can straighten and correct the coil and send it to the eye die of the wire drawing machine. When the coil wire head is first inserted into the wire feeding machine, it needs to be straightened by an additional wire head straightening mechanism so that it can be more conveniently fed into the wire drawing machine. The current wire head straightening mechanism is as follows Figure 5 As shown, a hydraulic cylinder is used to drive a knocking block 15, which is pressed on the wire head to straighten it.
[0003] However, after the striking block 15 straightens the wire end and rises, the wire of the disk element has a certain curvature, so when passing under the striking block, the wire will be lifted and rub against the striking block, causing the surface of the wire to be scratched, affecting the quality of the wire. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the utility model provides a scratch-free coil wire feeding machine, which uses a straightening guide wheel to straighten the coil wire end and can reduce friction when the wire passes through the straightening guide wheel, thereby avoiding scratches on the wire that affect quality.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a scratch-free wire feeding machine for coils, comprising a wire feeding machine bracket, a wire feeding machine bracket being provided with a wire straightening mechanism, the wire straightening mechanism comprising a straightening bracket, a driving mechanism being provided on the straightening bracket, a guide wheel bracket being provided on the driving mechanism, the guide wheel bracket being rotatably connected to a straightening guide wheel, a groove being provided on the straightening guide wheel, and the two sides of the guide wheel bracket being a wire end insertion side and a wire end extension side respectively.
[0006] Furthermore, a guide wheel groove is provided on the guide wheel bracket, the straightening guide wheel is located in the guide wheel groove, and the bottom of the straightening guide wheel is flush with the notch of the guide wheel groove.
[0007] Furthermore, a guide wheel shaft is provided in the guide wheel groove, the straightening guide wheel is rotatably connected to the guide wheel shaft, the guide wheel shaft passes through the guide wheel bracket at one end away from the wire feeding machine bracket, and a fixing groove is provided on the passing section, and a fixing plate corresponding to the fixing groove is provided on the guide wheel bracket, the fixing plate extends into the fixing groove, and the fixing plate is fixedly connected to the guide wheel bracket.
[0008] Furthermore, a guard plate is provided on the guide wheel bracket, and a clearance groove corresponding to the guide wheel shaft protruding section and the fixing plate is provided on the guard plate.
[0009] Furthermore, a baffle is provided on the side where the thread ends of the guide wheel bracket extend into.
[0010] Furthermore, the guide wheel bracket is provided with wire rollers on both sides on the side where the wire ends extend out.
[0011] Compared with the prior art, the beneficial effect of the present invention is that when the wire end of the disk element is straightened, the wire end is extended from the wire end extension side of the guide wheel bracket. When it is directly below the straightening guide wheel, the driving mechanism drives the guide wheel bracket to descend, so that the straightening guide wheel is pressed on the wire end, and the straightening guide wheel is straightened after repeated lifting and lowering. The wire end then passes through from the wire end extension side. At this time, the straightening guide wheel is located above the wire. When the wire passes by, even if it contacts the straightening guide wheel, the friction between the straightening guide wheel and the wire is reduced due to the rotation of the straightening guide wheel, thereby avoiding scratches on the wire and affecting the quality.
