Description

Technical Field

[0001] This utility model relates to the field of metal product technology, specifically to a wire drawing overhead wire feeding self-stop device. Background Technology

[0002] Wire drawing technology is widely used in the field of metal product manufacturing. Wire drawing, also known as wire drawing, specifically refers to the process of drawing metal wires or rods through a wire drawing machine so that the diameter, roundness, internal metallographic structure, surface finish, and straightness of the wires or rods meet the raw material processing requirements for the production of standard parts and other metal products. The wire drawing machine is the main equipment for wire drawing and can process copper wire, steel wire, rope wire, and other wires or rods.

[0003] According to Chinese Patent CN210131942U, a wire feeding device for a wire drawing machine includes a wire feeding frame with a base. A fence is welded around the wire feeding frame. This prevents the wire from spreading away from the wire feeding frame when too much wire is wound, thus avoiding wire tangling. Six evenly distributed longitudinal guide tubes are welded to the fence, each with a longitudinal guide hole and a transverse threaded hole. A rail is also provided on the fence, with six evenly distributed longitudinal guide rods welded to its lower side. These six guide rods are inserted into the guide holes of the six guide tubes, and a bolt for fixing the height of the guide rod is screwed into each threaded hole. The height of the rail is adjustable. When the wire needs to be wound onto the wire feeding frame, the height of the rail can be lowered, allowing the wire to be easily wound onto the frame. When the wire drawing machine is working and pulling the wire, the height of the rail can be raised, preventing the wire from spreading out of the rail and thus avoiding wire tangling.

[0004] The aforementioned device does not have a locking structure around the chassis when the wire is being laid out during wire drawing operations, thus preventing the chassis from automatically stopping. This would avoid the wire from being laid out with excessive length, which could affect the subsequent wire drawing effect. Therefore, a wire drawing overhead laying self-stop device is proposed to solve the above problem. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wire drawing overhead wire feeding self-stop device. It has the advantage of automatically locking and stopping the wire feeding reel when feeding wire, ensuring more accurate dimensional control during wire feeding. It solves the problem that the base is not equipped with a locking structure during wire feeding, so that the base has an automatic stopping effect, ensuring that the wire is fed out in excess length, which would affect the subsequent wire drawing effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire drawing overhead wire feeding self-stop device, including a base plate, a support seat fixedly connected to the top of the base plate, a rotating seat rotatably connected inside the support seat, a wire feeding frame installed on the top of the rotating seat, and a locking structure provided on the top of the base plate;

[0007] The locking structure includes a motor, which is fixedly connected to the top of the base plate. An annular plate is fixedly connected to the bottom of the wire feeding frame. A screw is fixedly connected to one end of the motor output shaft. A sleeve is threadedly connected to the outer surface of the screw. A locking block is fixedly connected to the top of the sleeve. A sliding block is elastically connected inside the support base. A first stud is threadedly connected inside the support base.

[0008] Furthermore, a protective frame is fixedly connected to the top of the base plate, a fixed plate is fixedly connected to the top of the protective frame, a top plate is detachably connected to the top of the fixed plate, and two guide rollers are rotatably connected to the top of the top plate.

[0009] Furthermore, an auxiliary bracket is fixedly connected to the outer surface of the protective frame, a second stud is threadedly connected to the inside of the fixing plate, and a connecting plate is fixedly connected to the bottom of the top plate. The connecting plate is detachably connected to the fixing plate via the second stud.

[0010] Furthermore, the support base has a number of ball bearings rotatably connected inside, and the rotating base is rotatably connected to the support base through the number of ball bearings.

[0011] Furthermore, an annular groove is formed on the inner outer surface of the rotating seat, and a spherical rod is fixedly connected to the side of the sliding block near the rotating seat, and the spherical rod is slidably connected to the annular groove.

[0012] Furthermore, the support base has a threaded hole inside, through which the first stud rotates inside the support base, and the right side of the first stud is in contact with the outer surface of the sliding block.

[0013] Furthermore, the locking block is wedge-shaped, and the annular plate has several locking grooves inside, through which the locking block is slidably connected to the annular plate.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. This wire drawing overhead wire feeding self-stop device allows the wire to be wound inside the feeding frame during wire drawing and feeding operations. One end of the wire then passes through the inside of two guide rollers. The rotating seat slowly rotates inside the support seat. When locking after feeding, the motor can be started to rotate the screw, causing the locking block connected to the sleeve to slide to the left and engage with the locking groove inside the annular plate, thus achieving the locking purpose. When assembling the rotating seat with the support seat, the first stud can be turned to press the sliding block, allowing the spherical rod to engage with the annular groove, ensuring that the rotating seat can be separated from the support seat for easy lubrication in subsequent use.

[0016] 2. The wire drawing overhead wire feeding self-stop device, by setting an auxiliary support on the left side of the protective frame, uses the stability of the triangle to reinforce the two wire rollers at the top of the protective frame when they rotate, ensuring a longer service life of the protective frame and minimizing the possibility of breakage.
