Description

Technical Field

[0001] This utility model relates to the field of silicon steel production technology, specifically to a tensioning and fixing device for silicon steel production. Background Technology

[0002] Silicon steel is a key material for motor and transformer cores. Its magnetic properties and surface quality are directly affected by the stretching process. The high brittleness and grain orientation sensitivity of silicon steel require precise control of clamping force and tension distribution during the stretching process. Therefore, a special stretching and fixing device is needed to achieve synchronous control of clamping, guiding and tension to ensure material performance and finished product quality.

[0003] However, most of the existing tensioning and fixing devices used in silicon steel production adopt a fixed-spacing guide structure, which cannot adapt to the flexible guiding requirements of materials with different thicknesses. The gap is too large, which can cause conveying deviation, or the gap is too small, which can cause surface indentation. In addition, the tension of the tensioning device is directly applied to the shaft of the unwinding structure. Without a buffer and diversion mechanism, the shaft of the unwinding pneumatic roller is easily fatigued and damaged due to instantaneous overload or frequent start-stop. Utility Model Content

[0004] The purpose of this invention is to provide a tensioning and fixing device for silicon steel production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Preferably, the drive mechanism includes a base plate, with four feet fixedly installed at the bottom corners of the base plate. The feet have fixing holes. A support rod is fixedly installed on the side of the base plate opposite to the feet. The stator of the electromagnetic brake is installed inside the support rod by bolts.

[0011] Preferably, a second pneumatic rod is telescopically mounted on the outer side of the unwinding pneumatic roller, and a second arc-shaped plate is fixedly mounted on the side of the second pneumatic rod opposite to the unwinding pneumatic roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This tensioning and fixing device for silicon steel production, through the dynamic outward expansion structure of the pneumatic rod and the arc plate combined with the adaptive rotation of the outer sheath, can adjust the guide gap according to the thickness of the silicon steel and maintain flexible contact, avoiding the material surface scratches or tension displacement problems caused by rigid clamping or gap mismatch of traditional fixing devices.

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.

[0022] Please see Figures 1-5 As shown, this utility model provides a technical solution:

[0023] A tensioning and fixing device for silicon steel production includes a fixed pneumatic roller 101. A first pneumatic rod 102 is telescopically mounted on the outer side of the fixed pneumatic roller 101. A first arc-shaped plate 103 is fixedly mounted on the side of the first pneumatic rod 102 relative to the fixed pneumatic roller 101. An outer sheath 104 is fixedly mounted on the side of the first arc-shaped plate 103 relative to the first pneumatic rod 102. One end of the fixed pneumatic roller 101 is mounted on the rotating end of a first pneumatic pulley 105 via a shaft. The side of the fixed pneumatic roller 101 relative to the first pneumatic pulley 105 is mounted on the rotor of an electromagnetic brake 106 via a shaft. A drive mechanism 201 is provided on the outer side of the electromagnetic brake 106 and the first pneumatic pulley 105.

[0024] The above scheme achieves stable support for the silicon steel coil by means of a fixed pneumatic roller, adjusts the extension and retraction of the first arc-shaped plate by means of a first pneumatic rod, clamps and guides the silicon steel coil by means of a first arc-shaped plate, provides flexible protection for the surface of the silicon steel by means of an outer sheath, drives the rotation of the fixed pneumatic roller by means of a first pneumatic pulley, controls the dynamic braking force of the fixed pneumatic roller by means of an electromagnetic brake, and coordinates the power of the pneumatic pulley and the brake by means of a drive mechanism.

[0025] In this embodiment, preferably, the driving mechanism 201 includes a base plate 202, with four support legs 203 fixedly installed at the bottom corners of the base plate 202. The support legs 203 have fixing holes 204. A support rod 205 is fixedly installed on the side of the base plate 202 opposite to the support legs 203. The stator of the electromagnetic brake 106 is installed in the support rod 205 by bolts.

[0026] The above scheme achieves the load-bearing and fixing function of the overall device through the base plate, the stable support function of the base plate through the legs, the position locking function of the legs through the fixing holes, the installation and positioning function of the electromagnetic brake through the support rod, and the integrated encapsulation function of the power components through the drive box.

[0027] In this embodiment, preferably, a drive box 206 is fixedly installed on the side of the base plate 202 away from the support rod 205, a box cover 301 is bolted to one side of the drive box 206, a drive motor 302 is fixedly installed on one side of the box cover 301, and a control panel 303 is fixedly installed on the side of the drive box 206 away from the box cover 301.

[0028] The above solution provides protection for the internal components of the drive box through the cover, enables power output to the reducer through the drive motor, and allows for centralized control of the device's operating parameters through the control panel.

[0029] In this embodiment, preferably, one side of the drive box 206 is installed to the fixed end of the first air pulley 105 by bolts, and a reducer 304 is fixedly installed inside the drive box 206 near the first air pulley 105. One side of the reducer 304 is installed at the drive end of the drive motor 302 through the shaft penetrating the box cover 301.

[0030] The above scheme allows for the adjustment of the output speed of the drive motor via a speed reducer, and the linkage between the speed reducer and the first pneumatic pulley enables the indirect driving of the fixed pneumatic roller.

[0031] In this embodiment, preferably, the reducer 304 is mounted on the rotating end of the second air pulley 305 via a shaft on the side opposite to the drive motor 302, the fixed end of the second air pulley 305 is mounted inside the drive box 206 via bolts, and the rotating end of the second air pulley 305 passes through the drive box 206 and is fixedly mounted on the side of the unwinding pneumatic roller 306.

[0032] The above scheme enables the rotational drive of the unwinding pneumatic roller through the second air pulley, and the unwinding pneumatic roller enables the unwinding and conveying of silicon steel coils.

[0033] In this embodiment, preferably, a second pneumatic rod 401 is telescopically installed on the outer side of the unwinding pneumatic roller 306, and a second arc-shaped plate 402 is fixedly installed on the side of the second pneumatic rod 401 relative to the unwinding pneumatic roller 306.

[0034] The above scheme allows for the extension and retraction adjustment of the second arc-shaped plate via the second pneumatic rod, and the second arc-shaped plate can also be used to clamp and limit the unwinding of the silicon steel coil.

[0035] In this embodiment, a stretching and fixing device for silicon steel production is used such that, during operation, the operator places the silicon steel coil around the outside of the second arc-shaped plate 402. The second pneumatic roller is driven by an air source via the second pneumatic pulley 305, generating air pressure. This causes the second pneumatic rod 401 to drive the second arc-shaped plate 402 to expand radially outward, achieving precise clamping and fixing of the silicon steel coil. After fixing, the silicon steel coil passes through the guide gap between the two sets of outer sheaths 104 and connects to the external stretching device. When the stretching device is started, the drive motor 302 operates via a shaft-linked reducer 304. The output end of the reducer 304 drives the rotating end of the second pneumatic pulley 305, causing the second pneumatic roller to rotate synchronously, achieving uniform unwinding of the silicon steel coil. Simultaneously, the stretching device applies traction force to ensure stable movement of the silicon steel along the conveying path. During this process, the first pneumatic pulley 105 is simultaneously connected to an air source to drive the first pneumatic roller, which pushes the first arc-shaped plate 103 outward through the first pneumatic rod 102, causing the outer sheath 104 to tightly adhere to the surface of the silicon steel and rotate adaptively with its movement, forming... The dynamic guiding adjustment structure can adapt to the guiding requirements of silicon steel coils of different thicknesses by adjusting the extension and retraction of the first pneumatic rod 102. When unwinding needs to be paused while the stretching device continues to work, the electromagnetic brake 106 applies braking torque to the fixed pneumatic roller 101. Combined with the contact friction between the first arc plate 103 and the outer sheath 104 on the silicon steel, the movement of the silicon steel is momentarily locked, preventing material relaxation caused by unwinding inertia. In addition, the device uses preset programmed instructions on the control panel 303, which are electrically connected to the internal electromagnetic brake 106, the drive motor 302, and the external stretching device via connecting lines. This allows for coordinated control of the start and stop of the electromagnetic brake 106, the air pressure parameters of the pneumatic pulley, and the speed of the drive motor 302. This achieves dynamic matching between unwinding tension and stretching speed, ensuring that the silicon steel maintains a constant tension during the stretching process. This avoids the risk of material deformation or breakage caused by sudden changes in tension. At the same time, the deceleration and buffering effect of the electromagnetic brake 106 reduces the instantaneous impact load on the shaft of the unwinding mechanism, extending the service life of the equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
