Description

Technical Field

[0001] This utility model relates to the field of automatic stop technology for material breakage, and in particular to an automatic stop device for material breakage of a drawing machine. Background Technology

[0002] A drawing machine is an industrial piece of equipment composed of mechanical devices, lubrication systems, electrical equipment, hydraulic systems, and pneumatic systems. It is used to draw metal materials. Drawing machines are used to process metals at room temperature. Their capacity is often expressed as the maximum drawing force. Based on their structure, drawing machines can be classified into chain drawing machines, hydraulic drawing machines, and drum drawing machines. The automatic stop device for material breakage in a drawing machine is a safety protection device. Its main function is to automatically stop the drawing machine in the event of breakage of the copper rod or other materials during the drawing process, thereby avoiding equipment damage, product quality problems, and potential safety accidents.

[0003] Existing automatic stop devices for material breakage in drawing machines typically monitor the copper rod as it is being fed onto the unloading machine after the drawing machine has straightened it. However, the surface of the copper rod is prone to accumulating impurities and dust, which are not promptly removed. This dust then floats onto the monitoring equipment, interfering with the accuracy of the material breakage monitoring device and causing the automatic stop device to frequently stop erroneously, resulting in reduced work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where impurities and dust easily adhere to the surface of copper rods, and if not treated in time, the dust will float onto the monitoring equipment, easily interfering with the monitoring accuracy of the material breakage monitoring device, and causing the automatic stop device to frequently stop erroneously, thus reducing work efficiency. Therefore, this invention proposes a material breakage automatic stop device for drawing machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a material breakage automatic stop device for a drawing machine, comprising a material breakage automatic stop frame, a photoelectric transmitter installed on the inner side of the material breakage automatic stop frame, a photoelectric receiver installed on the inner side of the material breakage automatic stop frame, a top plate installed at one top end of the material breakage automatic stop frame, an air pump installed at the top of the top plate, a connecting pipe connected to the side of the air pump, a blowing frame connected to one end of the connecting pipe, an electric lifting rod connected to the inner side of the top plate, a cleaning plate installed at the bottom of the electric lifting rod, and a cleaning brush installed on the outer side of the cleaning plate.

[0006] Preferably, a threaded rod is installed inside the material-cutting self-stop frame, a clamping frame is installed on the outside of the threaded rod, a cylinder is installed on the top of the clamping frame, a pressure plate is installed on the bottom of the cylinder, and a fixing plate is installed inside the clamping frame.

[0007] Preferably, the pressure plate and the fixing plate have multiple slots inside, and the bottom of the pressure plate is movably connected to the top of the fixing plate.

[0008] Preferably, one end of the threaded rod is connected to a translation motor, and the side of the translation motor is connected to one end of the material-cutting self-stopping frame.

[0009] Preferably, a hydraulic telescopic rod is installed on the top of the purging frame, and the top of the hydraulic telescopic rod is connected to the inner side of the top plate.

[0010] Preferably, a guide rod is installed through the inside of the clamping frame, and the guide rod is located inside the material breakage self-stop frame.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, a hydraulic telescopic rod extends and lowers the blowing frame, while simultaneously working with an air pump. This allows the high-pressure nozzles at the bottom of the blowing frame to blow high-pressure air onto the copper rod, ensuring that the high-pressure air is evenly distributed across the surface of the copper rod. This effectively cleans the surface of the copper rod, removing dust and impurities. Then, an electric lifting rod extends and lowers the cleaning plate, allowing the cleaning brushes to further remove dust and impurities from the surface of the copper rod. During the cleaning process, the nozzles of the blowing frame are angled, and the densely distributed cleaning brushes and the top baffle plate effectively reduce dust floating to the periphery of the monitor, thus reducing dust adhesion to the monitoring equipment. This improves the accuracy of copper rod monitoring, avoids signal interference and false reflections caused by dust and impurities, reduces the probability of misjudgment by the material cut-off automatic stop device, and ultimately improves production efficiency.

[0013] 2. In this utility model, the pressure plate is pushed down by the extension of the cylinder, so that the pressure plate is connected to the fixed plate, which is conducive to the effective clamping of multiple copper rods. In addition, multiple slots are opened inside the pressure plate and the fixed plate, which facilitates the clamping of copper rods of different diameters, improves the applicability and portability of the equipment, facilitates the monitoring operation of copper rods of different sizes at the same time, and improves the flexibility and diversity of operation.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-5 As shown, this utility model provides a technical solution: a material breakage self-stop device for a drawing machine, including a material breakage self-stop frame 1, a photoelectric transmitter 17 installed on the inner side of the material breakage self-stop frame 1, a photoelectric receiver 18 installed on the inner side of the material breakage self-stop frame 1, a top plate 2 installed at one end of the top of the material breakage self-stop frame 1, an air pump 3 installed on the top of the top plate 2, a connecting pipe 4 connected to the side of the air pump 3, a blowing frame 5 connected to one end of the connecting pipe 4, an electric lifting rod 7 connected to the inner side of the top plate 2, a cleaning plate 8 installed at the bottom of the electric lifting rod 7, a cleaning brush 9 installed on the outer side of the cleaning plate 8, and a hydraulic telescopic rod 6 installed on the top of the blowing frame 5, the top of the hydraulic telescopic rod 6 being connected to the inner side of the top plate 2.

[0023] In this embodiment, when the copper rod enters the equipment, it extends via the hydraulic telescopic rod 6, pushing the blowing frame 5 downwards. Simultaneously, the air pump 3 operates, causing the high-pressure nozzles at the bottom of the blowing frame 5 to blow high-pressure air onto the copper rod. This ensures the high-pressure air is evenly blown across the surface of the copper rod, effectively cleaning it and removing dust and impurities. Then, the electric lifting rod 7 extends, pushing the cleaning plate 8 downwards, allowing the cleaning brushes 9 to clean the dust and impurities on the surface of the copper rod, further removing deposits. During the cleaning process, the nozzles of the blowing frame 5 are angled, and combined with the densely distributed cleaning brushes 9 and the top baffle plate... To effectively reduce dust floating around the monitor and reduce dust adhesion to the monitoring equipment, it is beneficial to improve the accuracy of copper rod monitoring, avoid signal interference and false reflection caused by dust impurities, reduce the probability of misjudgment by the material cut-off automatic stop device, and thus improve production efficiency. The photoelectric transmitter 17 emits a laser beam to irradiate the surface of the copper rod, and the photoelectric receiver 18 is beneficial to receive the signal. The presence of copper rod is monitored by emitting and receiving light. When the copper rod passes normally, it will block the light, and the sensor will output a signal. Once the copper rod breaks, the light is no longer blocked, the sensor output signal changes, and the material cut-off automatic stop device is triggered.

[0024] Example 2: Figures 1-5 As shown, a threaded rod 11 is installed inside the self-stop frame 1 for material breakage. A clamping frame 13 is installed on the outside of the threaded rod 11. A cylinder 14 is installed on the top of the clamping frame 13. A pressure plate 15 is installed on the bottom of the cylinder 14. A fixing plate 16 is installed inside the clamping frame 13. Multiple slots are opened inside the pressure plate 15 and the fixing plate 16. The bottom of the pressure plate 15 is movably connected to the top of the fixing plate 16. One end of the threaded rod 11 is connected to a translation motor 10. The side of the translation motor 10 is connected to one end of the self-stop frame 1 for material breakage. A guide rod 12 is installed through the inside of the clamping frame 13. The guide rod 12 is located inside the self-stop frame 1 for material breakage.

[0025] In this embodiment, the threaded rod 11 is electrically driven to rotate by the translation motor 10, which in turn drives the clamping frame 13 to move outside the threaded rod 11, which is beneficial for conveying the copper rod. The guide rod 12 provides guidance. The cylinder 14 extends and pushes the pressure plate 15 down, so that the pressure plate 15 is connected to the fixed plate 16, which is beneficial for effectively clamping multiple copper rods. In addition, the pressure plate 15 and the fixed plate 16 have multiple slots inside, which facilitates the clamping of copper rods of different diameters, improves the applicability and portability of the equipment, facilitates the monitoring operation of copper rods of different sizes at the same time, and improves the flexibility and diversity of operation.

[0026] The working principle of this embodiment is as follows: In use, the cylinder 14 first extends to push the pressure plate 15 downwards, connecting the pressure plate 15 with the fixed plate 16. This facilitates the effective clamping of multiple copper rods. The pressure plate 15 and the fixed plate 16 have multiple slots inside, allowing for the clamping of copper rods of different diameters. Then, the translation motor 10 electrically drives the threaded rod 11 to rotate, thereby moving the clamping frame 13 outside the threaded rod 11, which facilitates the conveying of the copper rods. When the copper rods enter the equipment, the hydraulic telescopic rod 6 extends, pushing the blowing frame 5 downwards. Simultaneously, [the following text appears to be unrelated and possibly a separate instruction:] ...and... When the air pump 3 is activated, the high-pressure nozzles at the bottom of the blower frame 5 blow the copper rod under high pressure. Then, the electric lifting rod 7 extends and pushes the cleaning plate 8 down, allowing the cleaning brush 9 to clean the dust and impurities on the surface of the copper rod, further removing the attached substances. During the cleaning process, the nozzles of the blower frame 5 are designed at an angle. Together with the densely distributed cleaning brushes 9 and the top baffle plate, this can effectively reduce dust floating to the periphery of the monitor. During the transport process, the photoelectric transmitter 17 emits a laser beam to irradiate the surface of the copper rod, and the photoelectric receiver 18 is conducive to receiving signals, which facilitates real-time monitoring of the copper rod.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
