Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, and in particular to a synchronous power assembly for loading and unloading sheet metal roller presses. Background Technology

[0002] Roller presses are a common piece of equipment in sheet metal processing. They are primarily used to create patterns on the surface of sheet metal. Therefore, the raw material used is typically steel coils. However, as the steel coils are used, their internal stress is released instantaneously, resulting in a momentary expansion. This expansion affects the uniformity of the coil feed, causing the sheet metal being knurled to experience momentary retraction or expansion. This leads to disordered knurling on the sheet surface, affecting the knurling quality and ultimately resulting in a low yield of knurled steel sheets. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a synchronous power assembly for loading and unloading sheet metal roller presses.

[0004] This utility model is achieved by the following technical solution: a synchronous power assembly for loading and unloading sheet metal roll press, including a loading frame, the loading frame is used to support steel coils, a winding roller passes through the center of the steel coil, the end of the winding roller is supported on the loading frame, and an electric motor is provided on the loading frame to drive the winding roller to rotate.

[0005] A synchronization device is provided on one side of the feeding rack. The end of the steel coil passes through the synchronization device. The synchronization device includes a limiting member, a clamping member, and a control member. The limiting member is provided on the feeding rack. The end of the steel coil passes through the feeding rack. The clamping member is provided on the limiting member. When the steel coil passes through the limiting member, it contacts the clamping member. The control member is fixed on the feeding rack and is connected to the motor signal.

[0006] The limiting component includes an upper roller and a lower roller, with a gap between the upper roller and the lower roller for the plate to pass through. When the plate passes through the gap, the end face of the plate contacts the upper roller and the lower roller respectively. The upper roller and the lower roller are respectively provided with mounting holes on the side that contacts the plate, and the clamping component is disposed in the mounting hole.

[0007] The clamping component includes an electro-permanent magnet chuck, which is fixed inside the mounting hole and has its surface flush with the opening of the mounting hole, with the surface of the electro-permanent magnet chuck facing the plate.

[0008] The clamping component includes a clamping block and a rigid spring. One end of the rigid spring is fixed to the bottom of the mounting hole. The clamping block is inserted into the mounting hole and fixedly connected to the other end of the rigid spring. When the rigid spring is released, it pushes the clamping block out of the mounting hole and into contact with the end face of the plate.

[0009] An electromagnet is provided at the bottom of the mounting hole. The electromagnet is signal-connected to the control component. When the electromagnet is energized, it attracts the clamping block. When the electromagnet is de-energized, the clamping block separates from the electromagnet.

[0010] A buffer spring is provided on the side wall of the mounting hole. One end of the buffer spring is fixed to the inner wall of the mounting hole, and the other end of the buffer spring abuts against the side wall of the clamping block.

[0011] A sliding groove is formed on the side wall of the clamping block, and the other end of the buffer spring is inserted into the sliding groove and abuts against the sliding groove. The buffer spring is in a compressed state between the clamping block and the mounting hole.

[0012] Sensors are provided on the side of the upper roller and the lower roller that are in contact with the plate. The sensors are respectively arranged on both sides of the mounting hole. The end face of the sensor is flush with the end face of the upper roller and the lower roller. When the plate passes through the gap, it contacts the sensor. The sensor is signal connected to the control component.

[0013] The clamping block has an anti-slip film fixed on its end face facing the plate.

[0014] Compared to existing technologies, this invention addresses the issue of sudden stress release in steel coils. When the steel sheet passing through the gap is affected, a sensor on the sheet causes its signal to change. At this point, the electro-permanent magnetic chuck can directly attract the sheet, temporarily holding it in place. Once the stress release is complete, the chuck retracts its suction, allowing processing to continue normally. Alternatively, when signs of stress release appear, the sensor signal changes, causing the electromagnet to release the clamping block, allowing it to hold the sheet. Furthermore, the vibration of the sheet caused by stress release is absorbed by the buffer spring, reducing the impact of the steel coil's stress release on the sheet. Ultimately, this minimizes the impact on subsequent processing and improves processing quality. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Reference Figure 1-3 A power synchronization component for loading and unloading sheet metal roll forming includes a loading frame 1 for supporting steel coils 2. A winding roller passes through the center of the steel coil 2, and the end of the winding roller is mounted on the loading frame 1. A motor is mounted on the loading frame 1 to drive the winding roller to rotate. A synchronization device is provided on one side of the loading frame 1, through which the end of the steel coil 2 passes. The synchronization device includes a limiting member 3, a clamping member 4, and a control member 5. The limiting member 3 is located on the loading frame 1, and the end of the steel coil 2 passes through the loading frame 1. The clamping member 4 is located on the limiting member 3, and the steel coil 2 contacts the clamping member 4 when passing through the limiting member 3. The control member 5 is fixed on the loading frame 1 and is connected to the motor for signal transmission. In this embodiment, the control member 5 can be a conventional industrial control motherboard, microcontroller, or PLC, etc., used for receiving signals and transmitting commands.

[0021] In this embodiment, the limiting member 3 includes an upper roller 31 and a lower roller 32. A gap 33 is provided between the upper roller 31 and the lower roller 32 for the sheet metal to pass through. When the sheet metal passes through the gap 33, its end face contacts the upper roller 31 and the lower roller 32 respectively. Mounting holes 34 are provided on the sides of the upper roller 31 and the lower roller 32 that contact the sheet metal. The clamping member 4 is disposed within the mounting holes 34. Under normal conditions, the steel coil 2 rotates uniformly, meaning the sheet metal moves forward at a constant speed. If stress release occurs in the steel coil 2, the clamping member 4 will instantly clamp the sheet metal, causing the disturbance in the sheet metal caused by stress release to be transmitted to the clamping member 4. This reduces the impact on the sheet metal being processed, resulting in higher processing accuracy.

[0022] Reference Figure 1 and Figure 2In this embodiment, one implementation of the clamping component 4 is as follows: the clamping component 4 includes an electro-permanent magnetic chuck 41, which is fixed inside the mounting hole 34 with its surface flush with the opening of the mounting hole 34, and the surface of the electro-permanent magnetic chuck 41 facing the plate. That is, when the plate moves, if the steel coil 2 shows signs of stress release, the plate will exhibit abnormal vibration. At this time, the electro-permanent magnetic chuck 41 will release its suction force to attract the plate, stopping the vibration at the electro-permanent magnetic chuck 41. When the plate is normally released, the electro-permanent magnetic chuck 41 does not have suction force, and the plate can pass smoothly. Thus, when the steel coil 2 experiences stress release, the force of the stress release is transmitted through the plate to the electro-permanent magnetic chuck 41, reducing the impact on the plate being processed and resulting in higher processing accuracy.

[0023] Reference Figure 1 and Figure 3 Another embodiment of the clamping component 4 is as follows: The clamping component 4 includes a clamping block 43 and a rigid spring 42. One end of the rigid spring 42 is fixed to the bottom of the mounting hole 34. The clamping block 43 is inserted into the mounting hole 34 and fixedly connected to the other end of the rigid spring 42. When the rigid spring 42 is released, it pushes the clamping block 43 out of the mounting hole 34 to contact the end face of the plate. An electromagnet 44 is provided at the bottom of the mounting hole 34. The electromagnet 44 is signal-connected to the control component 5. When the electromagnet 44 is energized, it attracts the clamping block 43. When the electromagnet 44 is de-energized, the clamping block 43 separates from the electromagnet 44. When the electromagnet 44 is momentarily de-energized, the rigid spring 42 pops out and resets, pushing the clamping block 43 to clamp the plate. To increase the friction between the plate and the clamping block 43, an anti-slip film 47 can be fixed on the end face of the clamping block 43 facing the plate. When the plate moves, if the steel coil 2 shows signs of stress release, the plate will exhibit abnormal shaking. At this point, the electromagnet 44 is de-energized, causing the attraction between it and the clamping block 43 to disappear. The rigid spring pops out, pushing the clamping block 43 against the plate, stopping the vibration at the clamping block 43. During normal plate release, the clamping block 43 is attracted by the electromagnet 44, and the rigid spring 42 is compressed, allowing the plate to pass smoothly. Thus, when stress is released from the steel coil 2, the force of the released stress is transmitted through the plate to the clamping block 43, reducing the impact on the plate being processed and resulting in higher processing accuracy.

[0024] Based on this embodiment, a buffer spring 45 is provided on the side wall of the mounting hole 34. One end of the buffer spring 45 is fixed to the inner wall of the mounting hole 34, and the other end of the buffer spring 45 abuts against the side wall of the clamping block 43. A sliding groove 46 is formed on the side wall of the clamping block 43. The other end of the buffer spring 45 is inserted into the sliding groove 46 and abuts against the sliding groove 46. The buffer spring 45 is in a compressed state between the clamping block 43 and the mounting hole 34. When the vibration of the plate is transmitted to the clamping block 43, the clamping block 43 will sway left and right, and the impact force can be further dissipated by the buffering effect of the buffer spring 45. This reduces the impact on the plate being processed and improves the processing accuracy.

[0025] Reference Figure 1-3 In both of the above embodiments, both the permanent magnet chuck and the electromagnet 44 can be manually controlled. Of course, to achieve automatic control using the control component 5, sensors 51 are provided on the side of the upper roller 31 and lower roller 32 that contact the plate. The sensors 51 are respectively arranged on both sides of the mounting hole 34, with the end face of the sensor 51 flush with the end face of the upper roller 31 and lower roller 32. When the plate passes through the gap 33, it contacts the sensor 51, and the sensor 51 is signal-connected to the control component 5. In this embodiment, the control component 5 can be a conventional industrial control motherboard, microcontroller, or PLC, used to receive signals and transmit commands. During use, when the steel coil 2 is released normally, the plate passes through the space between the upper roller 31 and lower roller 32 at a uniform speed and contacts them. At this time, the plate provides a triggering force to the sensor 51, and because the plate passes through at a uniform speed, this triggering force remains constant or smoothly moves within a certain range. When the steel coil 2 experiences stress release, the released stress is transmitted through the sheet metal, eventually causing the force of the sheet metal compression sensor 51 to become uneven. When the control component 5 receives such an uneven signal, it can instruct the electro-permanent magnet chuck 41 to instantly have an attractive force to hold the sheet metal, or the electromagnet 44 to instantly release the clamping block 43, so that the clamping block 43 can instantly clamp the sheet metal. Through the conduction between the sheet metal and the clamping block 43 or between the sheet metal and the electro-permanent magnet chuck 41, the abnormal vibration of the sheet metal is transmitted and eliminated, thereby reducing the impact on the sheet metal being processed and achieving higher processing accuracy.

[0026] Compared to existing technologies, this invention addresses the issue of sudden stress release in the steel coil 2. When this stress is released, the sheet metal passing through the gap 33 is affected. Since the sheet metal has a sensor 51, its signal changes. At this point, the electro-permanent magnet chuck 41 can directly attract the sheet metal, temporarily holding it in place. Once the stress release is complete, the electro-permanent magnet chuck 41 retracts its suction, allowing processing to continue normally. Alternatively, when signs of stress release appear, the sensor 51 signal changes, causing the electromagnet 44 to release the clamping block 43, allowing it to hold the sheet metal. Furthermore, the vibration of the sheet metal caused by stress release is absorbed by the buffer spring 45, thus reducing the impact of stress release on the sheet metal and ultimately minimizing its influence on subsequent processing, thereby improving processing quality.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
