Description

Technical Field

[0001] This utility model belongs to the field of wire feeding frame technology, and particularly relates to the wire feeding frame of a medium drawing machine. Background Technology

[0002] In the processing of wires, cables, and metal wires, the drawing machine is a key wire drawing device, and the performance of its matching wire feeding stand directly affects the stability, processing accuracy, and production efficiency of the wire drawing process. The core function of the wire feeding stand is to provide stable support for the wire feeding reel, ensure orderly wire feeding, and guarantee precise control of the wire feeding length. It is a fundamental piece of equipment to ensure the smooth progress of subsequent drawing and forming processes.

[0003] The inventors have found that at least the following problems remain unsolved in the prior art. First, the clamping structure of traditional wire feeding frames is mostly fixed spacing or requires manual adjustment through multiple bolts. When it is necessary to change wire feeding reels of different sizes, it is necessary to repeatedly disassemble the fixing parts and adjust the clamping position, which is not only time-consuming and labor-intensive, but also increases the labor intensity of operators. Furthermore, improper adjustment can easily lead to unstable clamping of the wire feeding reel.

[0004] Secondly, the existing wire feeding racks often lack reliable one-way limit devices in their drive structure. During the wire feeding process, if external tension fluctuations, equipment vibrations, or sudden shutdowns occur, the wire feeding reel is prone to reverse rotation, causing the fed wire to become loose, tangled, or even knotted. This not only requires frequent manual intervention to straighten the wire, affecting production continuity, but may also cause equipment jamming due to wire tangling, increasing downtime and even posing safety hazards.

[0005] Moreover, traditional wire length control relies heavily on manual visual counting, which is not only inefficient but also prone to errors, making it difficult to meet the stringent requirements of high-precision machining for wire length. When the wire length reaches the preset value, there is a lack of automatic alarm reminder function, which often results in excessive or insufficient wire length due to operators failing to stop the machine in time, causing waste of raw materials or product scrap, and increasing production costs.

[0006] Therefore, we propose a wire feeding frame for a medium-speed drawing machine, which can solve the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1 to 5The wire feeding frame of the drawing machine includes a support 1. The front ends of both sides of the support 1 are rotatably connected to a first drive column 11 and a second drive column 12 via bearings. The ends of the first drive column 11 and the second drive column 12 away from the support 1 are respectively provided with a first clamping block 13 and a second clamping block 14. The second drive column 12 is provided with a drive mechanism inside, which is used to drive the second clamping block 14 to control the installation and removal of the wire feeding reel. The end of the first drive column 11 away from the first clamping block 13 is provided with a control mechanism, which is used to control the direction of the first drive column 11. The rear end inside the support 1 is provided with a detection mechanism, which is used to detect the wire feeding length of the wire feeding reel.

[0029] The first clamping block 13 and the second clamping block 14, symmetrically arranged on the inner side of the bracket 1, are used together to clamp and fix the pay-off reel. The first drive column 11 and the second drive column 12 realize the rotation of the pay-off reel for pay-off operations. The movement of the second clamping block 14 driven by the drive mechanism enables the quick installation and removal of the pay-off reel. The rotation direction of the first drive column 11 is precisely controlled by the control mechanism at the end of the first drive column 11 away from the first clamping block 13, ensuring a stable and orderly pay-off process. The detection mechanism set at the rear end of the inner side of the bracket 1 monitors the length of the wire released by the pay-off reel in real time, realizing precise control of the pay-off length.

[0030] Furthermore, the drive mechanism includes a slide bar 16 welded to the middle of one side of the second clamping block 14, and a lead screw 18 for driving the slide bar 16 to move left and right. The interior of the second drive column 12 is horizontally provided with a sliding groove 15. The end of the slide bar 16 away from the second clamping block 14 is slidably connected to the sliding groove 15. The first drive column 11 is fixedly connected to the middle of one side of the first clamping block 13, and the first clamping block 13 and the second clamping block 14 are symmetrically arranged.

[0031] When the clamping distance needs to be adjusted, the control slide 16 can slide horizontally within the slide groove 15, causing the second clamping block 14 to move closer to or further away from the first clamping block 13, thereby adapting to the installation requirements of different sized wire feeding reels and realizing convenient assembly and disassembly of the wire feeding reel.

[0032] Furthermore, the slider 16 has a horizontally formed connecting groove 17 inside, the lead screw 18 is threadedly connected to the connecting groove 17, the lead screw 18 is rotatably connected to the inner wall of the slide groove 15 through a bearing, and a knob 19 is fixedly installed at one end of the lead screw 18 located outside the slide groove 15.

[0033] When the knob 19, which is located outside the slide groove 15, is turned, the screw 18 rotates. Under the action of the threaded transmission, the slide bar 16 moves left and right along the slide groove 15, thereby driving the second clamping block 14 to move synchronously. This precisely adjusts the distance between the first clamping block 13 and the second clamping block 14, so as to achieve stable clamping or quick disassembly of the wire feeding reel.

[0034] Furthermore, the control mechanism includes a ratchet 21 for controlling the steering of the first drive column 11 and a limiting strip 23. A control groove 2 is provided on the side of the bracket 1 away from the second drive column 12. One end of the first drive column 11, located inside the control groove 2, is fixedly connected to the middle of the ratchet 21. An installation groove 22 is provided on the inner wall of the top of the control groove 2. The top of the limiting strip 23 is rotatably connected to the installation groove 22 through a rotating shaft. The bottom end of the limiting strip 23 is movably connected to the ratchet 21, and the size of the limiting strip 23 matches that of the ratchet 21.

[0035] When the first drive column 11 drives the ratchet 21 to rotate in the forward direction, the limiting strip 23 can slide along the tooth surface of the ratchet 21; if the ratchet 21 attempts to rotate in the reverse direction, the limiting strip 23 will be engaged in the tooth groove of the ratchet 21 to prevent it from rotating, thereby restricting the first drive column 11 to rotate only in one direction and avoiding reverse rotation during the wire feeding process; it should be noted that the rotation direction of the ratchet 21 is the direction in which the wire feeding reel rotates to release the wire.

[0036] Furthermore, the detection mechanism includes a measuring wheel 32 for guiding the wire, a Hall sensor 35 for detecting the number of rotations of the measuring wheel 32, and a ringing alarm 38 for automatic alarm. A fixing frame 31 is fixedly installed on the rear side of the inner wall of the bottom end of the bracket 1 by a vertical column 3. A drive rod 33 is horizontally inserted through and fixedly installed in the middle of the measuring wheel 32. The drive rod 33 is rotatably connected to the inner walls on both sides of the fixing frame 31 through bearings.

[0037] The wire is wrapped around the surface of the measuring wheel 32. During wire release, the tension of the wire drives the measuring wheel 32 to rotate synchronously, which in turn drives the rod 33 to rotate along with the measuring wheel 32. The Hall sensor 35 detects the number of rotations of the measuring wheel 32 in real time. When the wire release length reaches a set threshold, the alarm 38 automatically triggers, achieving precise monitoring and safety warning of the wire release process. It should be noted that an anti-slip pad can be placed on the outside of the measuring wheel 32 to prevent the wire from slipping.

[0038] Furthermore, a measuring groove 34 is provided inside one side of the fixed frame 31. A magnet 36 is fixedly connected to one end of the drive rod 33 located inside the measuring groove 34. A Hall sensor 35 is fixedly connected to the inner wall of the top of the measuring groove 34. The magnet 36 is installed in a ring at equal intervals on the outside of the drive rod 33, and the magnet 36 corresponds to the Hall sensor 35.

[0039] When the drive rod 33 rotates with the measuring wheel 32, the magnet 36 rotates synchronously. When the magnet 36 rotates to the upper end of the drive rod 33, it can align with the Hall sensor 35. The Hall sensor 35 can transmit data to the controller 37 to detect the number of rotations of the drive rod 33, that is, the number of rotations of the measuring wheel 32, and further detect the wire length.

[0040] Furthermore, the ringing alarm 38 is fixedly connected to the top of the bracket 1 on the side near the first drive column 11, and a controller 37 is provided on the side of the bracket 1 where the ringing alarm 38 is installed.

[0041] The controller 37 receives the rotation number signal transmitted by the Hall sensor 35, calculates the actual wire length, and compares it with the preset length threshold. When the wire length reaches the threshold, the controller 37 immediately triggers the alarm 38 to issue an alarm signal, reminding the operator to handle the situation in time, thereby realizing automated monitoring and early warning of the wire laying process.

[0042] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
