Description

Technical Field

[0001] This utility model relates to the field of steel wire processing technology, and in particular to a device for detecting the breakage of semi-finished steel wire during pull-out. Background Technology

[0002] Wire drawing is a key process that plastically deforms raw materials through a drawing die to achieve a predetermined diameter and performance requirements. During this process, the steel wire undergoes multiple drawing passes, gradually reducing its cross-sectional area and increasing its strength. Existing wire breakage detection devices primarily operate based on photoelectric principles.

[0003] While photoelectric detection devices avoid mechanical wear, they are extremely sensitive to changes in ambient light, especially in dusty drawing workshops where lens contamination is frequent, leading to unstable detection signals. Furthermore, most existing detection devices are designed for specific wire specifications, lacking sufficient versatility and adaptability. When the wire material, diameter, or drawing speed changes, complex readjustments or component replacements are often required, undoubtedly increasing production costs and maintenance complexity. Utility Model Content

[0004] The purpose of this invention is to provide a semi-finished steel wire pull-out breakage detection device that can overcome the shortcomings of existing wire breakage detection devices.

[0005] To achieve the above objectives, a semi-finished steel wire pull-out breakage detection device is provided, including a support base and a steel wire body. A support frame is fixedly connected to the upper side wall of the support base. A sliding inner groove is provided on the front side wall of the support frame near the left end. A sliding seat is slidably connected inside the sliding inner groove. A movable wire guide wheel is rotatably connected to the front side wall of the sliding seat. A touch switch is installed on the left inner wall of the sliding inner groove.

[0006] A detection frame is fixedly connected to the upper side wall of the support base. A detection wheel is rotatably connected to the front side wall of the detection frame. A rotating frame is rotatably connected to the rear side wall of the detection wheel. A guide rod is rotatably connected to the front right side wall of the rotating frame. A limit switch is installed on the rear side wall of the detection frame.

[0007] According to the aforementioned semi-finished steel wire pull-out breakage detection device, the steel wire body passes sequentially through the guide wire seat, the movable guide wire wheel, the second guide wire wheel, the first guide wire wheel, and the detection wheel. The steel wire body surrounds the detection wheel once. The steel wire body cooperates with the lower side wall of the guide rod. After the steel wire body breaks, it no longer supports the guide rod, causing the lower end of the rotating frame to rotate, thereby colliding with the detection end of the limit switch and sending a signal.

[0008] According to the aforementioned semi-finished steel wire pull-out breakage detection device, the touch switch is positioned opposite the sliding seat, and when the sliding seat collides with the touch switch, the touch switch will emit a signal.

[0009] According to the aforementioned semi-finished steel wire pull-out breakage detection device, a support spring is installed between the right side wall of the sliding seat and the right inner wall of the sliding inner groove. After the main body of the steel wire near the movable guide wheel breaks, the main body of the steel wire no longer pulls the movable guide wheel. The support spring pushes the movable guide wheel to move to the left, thereby causing the sliding seat to collide with the trigger switch.

[0010] This utility model has the following beneficial effects:

[0011] 1. Compared with existing technologies, this device is equipped with a touch switch and a limit switch, which work closely together to quickly detect abnormal states of the steel wire. Once the steel wire breaks during the drawing process, the touch switch and limit switch respond immediately, issuing a warning signal. This dual detection mechanism greatly improves detection accuracy, ensuring that wire breaks are detected promptly during production, thus avoiding production delays and material waste caused by undetected wire breaks, and significantly improving production efficiency and product quality.

[0012] 2. Compared with existing technologies, this device greatly improves the accuracy and reliability of detection through touch switches and limit switches, and solves the problems of existing detection devices being sensitive to ambient light and having lenses that are easily contaminated.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4 This utility model discloses a semi-finished steel wire pull-out breakage detection device, which includes a support base 1. The support base 1 is made of high-strength cast iron and is precision cast and machined. Its upper sidewall is designed with multiple sets of fixing holes, which are bolted to the ground or other foundation platform to ensure excellent stability and shock resistance of the entire device during steel wire pull-out. A support frame 2 is fixedly connected to the center of the upper sidewall of the support base 1. The support frame 2 is a rectangular frame structure made of high-quality carbon steel and refined through laser cutting, bending, and welding processes. A sliding inner groove 205 is carefully set on the front sidewall near the left end. The inner surface of the sliding inner groove 205 is machined by a high-precision CNC machine tool to ensure that the surface roughness is lower than Ra1.6, thereby ensuring smooth operation and precise positioning of the subsequent sliding components.

[0022] A sliding seat 401 is embedded in the sliding inner groove 205 of the support frame 2. The sliding seat 401 is made of lightweight aluminum alloy, and its front side wall is rotatably connected to the movable guide wheel 4. The left inner wall of the sliding inner groove 205 is directly opposite the sliding seat 401. The touch switch 204 is a micro switch from a well-known brand, which has high sensitivity and fast response capability. Its triggering force has been precisely adjusted to ensure that it can output an electrical signal instantly when a collision signal is received. Between the right side wall of the sliding seat 401 and the right inner wall of the sliding inner groove 205, a high-quality piano wire made with a special heat treatment process is installed. The support spring 206 is in a moderately compressed state during normal operation of the device, accumulating strong elastic potential energy. Once the main body of the steel wire 5 breaks, its instantaneous release of elastic force will quickly push the sliding seat 401 to the left, causing it to collide precisely with the touch switch 204 and trigger the wire break signal.

[0023] A detection frame 3 is fixedly installed on the right side of the upper sidewall of the support base 1. The detection frame 3 is made of high-quality carbon steel similar to that of the support frame 2, and its front sidewall is rotatably connected to the detection wheel 301. The rear sidewall of the detection wheel 301 is rotatably connected to the rotating frame 302. The rotating frame 302 is made of lightweight aluminum alloy and is formed by precision die casting. Its right front sidewall is rotatably connected to the guide rod 303. The guide rod 303 is made of high-strength stainless steel and its surface is finely polished to ensure that the steel wire body 5 slides smoothly on its lower sidewall. Its axis is also connected to the rotating frame 302 through a high-precision bearing to ensure the flexibility and accuracy of the entire transmission chain.

[0024] On the rear wall of the detection frame 3, the limit switch 304 is an industrial-grade limit switch with excellent anti-interference capability and stable output performance. Its trigger rod is precisely aligned with the movement trajectory of the rotating frame 302. When the wire body 5 is running normally, the guide rod 303 is supported by the wire body 5 and remains balanced; however, once the wire body 5 breaks, the guide rod 303 loses its support and droops under its own weight, causing the rotating frame 302 to rotate around the connection point. Its end precisely strikes the trigger rod of the limit switch 304, issuing a wire break alarm signal.

[0025] The steel wire body 5 passes sequentially through the guide seat 203, the movable guide wheel 4, the second guide wheel 202, the first guide wheel 201, and the detection wheel 301. The guide seat 203, the first guide wheel 201, and the second guide wheel 202 effectively guide the steel wire body 5 to run along a predetermined trajectory. The steel wire body 5 cleverly loops around the detection wheel 301, tightly fitting against the lower side wall of the guide rod 303. This ingenious path design ensures that the steel wire body 5 maintains stable tension throughout the drawing process and ensures that each detection component can monitor the operating status of the steel wire body 5 in real time.

[0026] During actual operation, the wire body 5 moves continuously under the drive of the drawing equipment. When the wire body 5 breaks, the support spring 206 quickly pushes the sliding seat 401 to the left, colliding with and triggering the switch 204, sending a wire breakage signal. Simultaneously, the wire body 5 loses support for the guide rod 303, causing the guide rod 303 to droop and rotate the rotating frame 302, colliding with the limit switch 304, sending another wire breakage signal. These two independent detection mechanisms work together to ensure the timely and accurate issuance of wire breakage signals, effectively avoiding the risk of missed detection due to the failure of a single detection point, and providing comprehensive wire breakage detection assurance for the wire drawing production process.

[0027] Unless otherwise specified, the constituent units of this utility model are obtained from conventional commercial channels or manufactured by conventional methods. Their specific structure, working principle, and possible control methods and spatial arrangement methods can adopt conventional choices in the field and should not be regarded as the innovation of this utility model. This is understandable to those skilled in the art, and this utility model patent will not be further elaborated in detail.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
