Description

Technical Field

[0001] This utility model relates to the field of bar material flaw detection and demagnetization technology, specifically an integrated bar material flaw detection and demagnetization device. Background Technology

[0002] Bar stock refers to solid, long strips of steel or other metallic or non-metallic materials with regular cross-sections such as circles, squares, and hexagons, and a length much greater than the cross-sectional dimensions. Bar stock is delivered in straight bars and is mainly used in building structures, machining, and hardware manufacturing. It can be produced through processes such as rolling, drawing, and forging. However, metal workpieces may retain residual magnetism after magnetic particle testing or magnetization, potentially attracting impurities such as iron filings and dust, affecting the accuracy of subsequent cutting and grinding processes. A demagnetizing device is used to eliminate residual magnetism on the surface and inside of metal workpieces, primarily applied in the magnetic treatment stages before and after non-destructive testing. Its working principle is to generate an alternating magnetic field, causing the magnetic domains within the workpiece to align randomly, thereby neutralizing the residual magnetism. However, existing bar stock demagnetizing devices cannot accurately test the surface, resulting in poor measurement results. Furthermore, they cannot clean the surface of the demagnetized bar stock, making them inconvenient to use. Utility Model Content

[0003] The purpose of this utility model is to provide an integrated bar material flaw detection and demagnetization device to solve the problems mentioned in the background art, such as the inability to accurately detect flaws on the surface, poor measurement results, and the inability to clean the surface of the bar material after demagnetization, which is inconvenient to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an integrated bar material flaw detection and demagnetization device, including a workbench, wherein linear motors are symmetrically embedded in the surface of the workbench, and a support frame is connected to the surface of the linear motor's drive component.

[0005] The surface of the support frame is equipped with a demagnetizer, and the surface of the support frame is symmetrically equipped with connecting rods, with a cleaning block fixedly connected to the end of the connecting rod. The surface of the workbench is equipped with a placement plate, and the surface of the support frame is connected with a mounting rod, with an ultrasonic flaw detector installed at the bottom of the mounting rod. The surface of the workbench is connected with a collection mechanism, which includes: a collection trough connected to the surface of the workbench, a fan installed on the surface of the workbench, and a collection box connected to the surface of the workbench. The inside of the collection box is equipped with a filter screen, and a telescopic tube connects the collection box and the collection trough.

[0006] Preferably, the support frame and the worktable are slidably connected, and the connecting rod and the worktable are also slidably connected.

[0007] Using the above technical solution, the driving component of the linear motor drives the support frame to move, so that the support frame moves on the surface of the worktable.

[0008] Preferably, the demagnetizer and the ultrasonic flaw detector are symmetrically arranged on both sides of the collection tank, and the collection tank and the worktable are slidably connected.

[0009] Using the above technical solution, the demagnetizer first demagnetizes the bar, and then the bar is inspected for flaws by an ultrasonic flaw detector.

[0010] Preferably, the cleaning blocks are symmetrically arranged on both sides of the placement plate, and the surfaces of the cleaning blocks on both sides of the collection trough are connected, with the collection trough located at the bottom of the placement plate.

[0011] Using the above technical solution, the end of the cleaning block contacts the surface of the rod, removing magnetic debris from the surface of the rod.

[0012] Preferably, the placement plate is disposed inside the demagnetizer, and the demagnetizer and the worktable are slidably connected.

[0013] Using the above technical solution, the demagnetizer disinfects the rods placed on the surface of the placement plate.

[0014] Preferably, the placement plate is configured as an arc-shaped structure, and the surface of the placement plate is continuously provided with holes.

[0015] Using the above technical solution, debris on the surface of the placement plate falls into the collection tank through the holes on the surface of the placement plate.

[0016] Preferably, the air inlet pipe of the fan is connected to the collection box, and the air inlet of the fan is installed at the bottom of the filter screen.

[0017] Using the above technical solution, the fan is started, and the air carries the debris on the surface of the bar into the inside of the collection tank.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the integrated bar material flaw detection and demagnetization device:

[0019] 1. The device is equipped with a demagnetizer, a linear motor, and an ultrasonic flaw detector. The linear motor drives the support frame to move, so that the bar first enters the demagnetizer for demagnetization. After demagnetization, the debris on the surface of the demagnetizer is swept away by a cleaning block. Then, it is moved to the ultrasonic flaw detector for flaw detection. There is no need to manually transfer the workpiece, which ensures that the demagnetization and flaw detection processes of each bar are completed continuously on the same equipment, thus improving work efficiency.

[0020] 2. A collection structure is set up. When the support frame moves, the cleaning block moves with it and sticks to the surface of the rod, which can effectively remove the magnetic debris remaining on the surface of the rod after demagnetization. At the same time, the fan is connected to the collection box through the air inlet pipe. After starting, it can generate negative pressure, which allows the air to carry the debris through the collection groove and telescopic pipe into the collection box. After being filtered by the filter screen, the debris is collected, which improves the practicality of the device. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution: an integrated bar material flaw detection and demagnetization device, including a workbench 10, a linear motor 20, a support frame 30, a demagnetizer 40, a connecting rod 401, a cleaning block 402, a placement plate 403, an installation rod 404, an ultrasonic flaw detector 405, a collection tank 50, a fan 501, a collection box 502, a filter screen 503, and a telescopic tube 504;

[0031] This bar material flaw detection and demagnetization device facilitates flaw detection and demagnetization. The specific implementation method is as follows:

[0032] Linear motors 20 are symmetrically embedded in the surface of the workbench 10. A support frame 30 is connected to the surface of the driving component of the linear motor 20. A demagnetizer 40 is mounted on the surface of the support frame 30, and connecting rods 401 are symmetrically mounted on the surface of the support frame 30. A cleaning block 402 is fixedly connected to the end of the connecting rod 401. A placement plate 403 is mounted on the surface of the workbench 10, and a mounting rod 404 is connected to the surface of the support frame 30. An ultrasonic flaw detector 405 is mounted at the bottom of the mounting rod 404. The support frame 30 and the workbench 10 are slidably connected, as are the connecting rods 401 and the workbench 10. The placement plate 403 is located inside the demagnetizer 40, and the demagnetizer 40 is slidably connected to the workbench 10. The placement plate 403 has an arc-shaped structure, and its surface is continuously perforated.

[0033] The rod is placed on the surface of the placement plate 403, and one side of the rod is moved to the surface of the demagnetizer 40. The demagnetizer 40 is then activated to demagnetize the rod. After demagnetization, the linear motor 20 is activated, causing its drive mechanism to move the support frame 30. The support frame 30 then moves the demagnetizer 40, removing it from the surface of the demagnetized rod. Simultaneously, the support frame 30 moves the connecting rod 401 across the worktable 10, causing the connecting rod 401 to move the cleaning block 402, which cleans the surface of the rod, removing debris. The linear motor is then turned off. Machine 20 fixes the position of demagnetizer 40, and then starts demagnetizer 40 to disinfect the raised bar. After demagnetization is completed, linear motor 20 is started to drive demagnetizer 40 to move forward. Support frame 30 drives cleaning block 402 to clean the surface of the second demagnetized bar. At this time, support frame 30 drives mounting rod 404 to move ultrasonic flaw detector 405 to the surface of the first demagnetized bar. At this time, ultrasonic flaw detector 405 is turned on to detect flaws in the bar.

[0034] This bar material flaw detection and demagnetization device facilitates the removal of debris from the bar material surface. The specific implementation method is as follows:

[0035] The surface of the workbench 10 is connected to a collection mechanism, which includes: a collection trough 50 connected to the surface of the workbench 10; a fan 501 installed on the surface of the workbench 10; a collection box 502 connected to the surface of the workbench 10; a filter screen 503 installed inside the collection box 502; a telescopic pipe 504 connecting the collection box 502 and the collection trough 50; a demagnetizer 40 and an ultrasonic flaw detector 405 symmetrically arranged on both sides of the collection trough 50, with the collection trough 50 and the workbench 10 being slidably connected; cleaning blocks 402 symmetrically arranged on both sides of the placement plate 403, with the surfaces of the cleaning blocks 402 connected to each other on both sides of the collection trough 50; the collection trough 50 being located at the bottom of the placement plate 403; the air inlet pipe of the fan 501 being connected to the collection box 502; and the air inlet of the fan 501 being installed at the bottom of the filter screen 503.

[0036] When the cleaning block 402 cleans the rod, it moves to move the collection trough 50. As the collection trough 50 moves, it causes the telescopic tube 504 to extend, allowing the collection trough 50 to slide on the surface of the workbench 10. The fan 501 is then activated, and the fan 501 drives airflow through the rod into the collection trough 50. At this time, the airflow carries debris into the collection trough 50. The debris swept off by the cleaning block 402 falls into the collection trough 50. By cooling the surface of the rod, the debris passes through the collection trough 50 and enters the telescopic tube 504. Through the telescopic tube 504, the debris enters the collection box 502. The filter screen 503 inside the collection box 502 filters the debris, causing it to remain on the surface of the filter screen 503. The filtered gas then enters the fan 501 and is discharged through the fan 501.

[0037] Working principle: When using this integrated bar material flaw detection and demagnetization device, a demagnetizer 40, a connecting rod 401, a cleaning block 402, and a placement plate 403 are provided to facilitate flaw detection and demagnetization. A fan 501, a collection box 502, a filter screen 503, and a telescopic tube 504 are provided to facilitate the removal of debris from the bar material surface, increasing the overall practicality.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
