Description

Technical Field

[0001] This utility model relates to the field of electromagnetic flat wire technology, and in particular to a test device for narrow-side bending of electromagnetic wire. Background Technology

[0002] Magnetite wire is a special type of wire that plays a vital role in electrical equipment. It is made of conductive material, typically copper or aluminum, and encased in a high-quality insulating material. Magnetite wire possesses excellent conductivity, enabling efficient current transmission, while its insulation layer effectively prevents current leakage and short circuits, ensuring the safe and stable operation of the circuit. Due to its unique properties, magnetite wire is widely used in various electromagnetic devices, such as motor windings and transformer coils. It is a key component for realizing the conversion between electrical energy and magnetic energy, providing crucial support for the normal operation of numerous electrical devices in modern industry and daily life.

[0003] The narrow-side bending test of electromagnetic wire can clearly reveal its performance under narrow-side bending conditions, determining whether it is prone to breakage, cracking, or insulation damage. This helps predict the performance of electromagnetic wire in practical applications. Simultaneously, this test also serves as a means of inspecting the quality of the electromagnetic wire's insulation layer, revealing whether the insulation layer maintains good integrity and insulation performance during bending, thus preventing electrical faults such as short circuits caused by insulation damage.

[0004] The narrow-side bending test of electromagnetic wire plays an important role, but most of the existing electromagnetic wire narrow-side bending test devices cannot control the bending angle of the electromagnetic wire, and therefore cannot conduct accurate tests. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electromagnetic wire narrow-side bending test device, which aims to improve the problem that the bending angle of the electromagnetic wire cannot be controlled when the test device performs a bending test on the narrow side of the electromagnetic wire, resulting in a single test result.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electromagnetic wire narrow-side bending test device, comprising a base plate, a first base plate fixedly connected to the top of the base plate, a first sliding groove formed inside the first base plate, a second base plate fixedly connected to the top of the first base plate, an inlet plate fixedly connected to the top of the second base plate, a first telescopic rod fixedly connected to the left side of the inlet plate, a first limiting plate fixedly connected to one end of the first telescopic rod, a fixing frame fixedly connected to the top of the first base plate, an upper top plate fixedly connected to the bottom of the fixing frame, a second sliding groove formed inside the upper top plate, a limiting block fixedly connected to the top of the second sliding groove, two sliding plates slidably connected inside the second sliding groove, a third telescopic rod fixedly connected to an adjacent side of the two sliding plates, cylinders fixedly connected to the bottom of the two sliding plates, a force-applying plate fixedly connected to one end of the two cylinders, a second limiting plate slidably connected inside the first base plate, a second telescopic rod fixedly connected to the left side of the second limiting plate, and a fixing mechanism fixedly connected to one end of the second telescopic rod.

[0007] The above technical solution allows for bending of the electromagnetic wire from zero to 180 degrees by moving the first limiting plate, the second limiting plate, and the upper limiting plate, thus enabling testing of the narrow side of the electromagnetic wire under various bending angles.

[0008] As a further description of the above technical solution:

[0009] The fixing mechanism includes a bracket, the bottom of which is fixedly connected to the top of a first base plate. Connecting plates are fixedly connected to both the front and rear sides of the bracket. A rotating shaft is slidably connected inside the connecting plates. A crank is fixedly connected to one end of the rotating shaft. A winding drum is rotatably connected to the outer wall of the rotating shaft. Fixing plates are fixedly connected to both the front and rear sides of the winding drum. Spring bolts are fixedly connected to the top of both fixing plates. Clamping plates are fixedly connected to one end of both spring bolts.

[0010] The above technical solution allows one end of the electromagnetic wire to be fixed to a spool. By rotating the handle, the spool can be wound up, thereby adjusting the position of the electromagnetic wire and allowing bending tests to be conducted at different positions on the narrow side of the electromagnetic wire.

[0011] As a further description of the above technical solution:

[0012] The top of the first base plate is threaded with multiple bolts, and the bottom end of each bolt is threaded with a base.

[0013] The above technical solution allows the first base plate to be fixed to the base using bolts, thereby further ensuring the stability of the device.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the winding drum is provided with a spiral groove, and the outer surface of the spiral groove is rough.

[0016] The above technical solution involves setting spiral grooves on the outer wall of the winding drum, which not only makes the electromagnetic wire more firmly fixed on the winding drum, but also allows the electromagnetic wire to wind along the spiral grooves when a large amount is wound on the winding drum, thus making the distribution on the shaft uniform.

[0017] As a further description of the above technical solution:

[0018] Both the inlet plate and the first limiting plate are fixedly connected to limiting blocks, and the limiting blocks have limiting grooves inside.

[0019] The above technical solution allows the presence of a limiting block to stabilize the position of the electromagnetic wire, preventing it from bending at a horizontal angle and thus affecting the test results.

[0020] As a further description of the above technical solution:

[0021] An anti-slip sleeve, made of plastic, is fixedly connected to the outer wall of the crank handle.

[0022] Through the above technical solution, the presence of the anti-slip sleeve makes it easier for workers to wind electromagnetic wires.

[0023] As a further description of the above technical solution:

[0024] A switch is fixedly connected to the front side of the first base plate, and a dust cover is rotatably connected to the top of the switch.

[0025] Through the above technical solution, the switch can control the opening of the entire device, and the presence of a dust cover can extend the service life of the switch.

[0026] As a further description of the above technical solution:

[0027] An alarm light is fixedly connected to the top of the mounting bracket, and the alarm light is electrically connected to a switch.

[0028] The present invention has the following advantages: the alarm light can sound an alarm when the device has a safety problem, and the electrical connection with the switch can shut down the device immediately.

[0029] In this invention, after the electromagnetic wire enters the device, the telescopic rod is activated, causing the first limiting plate, the second limiting plate, and the upper limiting plate to move in the slide groove. At the same time, the force plate is moved down by the cylinder, which can bend the electromagnetic wire from zero degrees to 180 degrees. Furthermore, it can be used to test the narrow side of the electromagnetic wire under various bending angle conditions.

[0030] In this invention, by moving one end of the electromagnetic wire onto the reel and fixing it with a spring bolt, the operator turns the crank to reel in the wire, thereby further adjusting the position of the electromagnetic wire. This allows for bending tests on different positions of the narrow side of the electromagnetic wire tested by the testing device, greatly improving the testing capability of the device.
