Description

Technical Field

[0001] The invention relates to the technical field of punching devices, in particular to an ultra-thin silicon steel sheet punching device. Background Art

[0002] Silicon steel sheets are the core soft magnetic material of power electronic equipment. Their performance directly affects the efficiency, volume and temperature rise of electromagnetic devices. As power electronics technology develops towards high frequency, high efficiency and miniaturization, the quality requirements for silicon steel sheets themselves are becoming increasingly higher. The existing silicon steel sheet production process mostly adopts the punching method. However, there are still some problems in the use of existing punching devices, as follows:

[0003] The finished products produced by the existing punching device during stamping all fall directly into the collection trough below, and then undergo subsequent collection and reprocessing to complete the production processing of the silicon steel sheets. However, this method will first increase the complexity of the entire production process, resulting in low production efficiency. Secondly, the products punched out by the existing punching device are directly stacked and collected without processing, and the burrs generated by the stamping will scratch the subsequent dropped products, causing product damage. Finally, in order to reduce the damage of the punch to the product, the punching device will spray lubricating oil on the mold and the corresponding punch surface. This lubricating oil will cause the punched silicon steel sheets to stick together after being stacked and collected, making it difficult to separate them later, further reducing the production efficiency of the entire silicon steel sheet. For this reason, we propose an ultra-thin silicon steel sheet punching device. Summary of the Invention

After being discharged, the punches supported on the top will fall to the bottom for polishing after moving back to their original position in the opposite direction, ensuring the continuity of the operation of the entire device.

[0040] See also Figure 1-6 A device for punching ultra-thin silicon steel sheets includes a blanking and collecting assembly 10, which includes a bottom box 101. A lifting structure 102 is fixedly installed on the top of the bottom box 101. An outer tube 103 is movably sleeved on the lifting structure 102.

The air guide tube is made of hard material, so that the flow of oil inside the linkage trigger component 8 can drive the flow of oil inside the bottom box 101, and then realize that during the punching stage, the support plate 104 can be driven to move up synchronously with the downward movement of the pressure plate 5 to ensure its bearing on the punching sheet. After the punching stage is completed, the weight of the support plate 104 can be used to compress the oil inside the jacking structure 102, so that the support plate 104 automatically falls back to the bottom, so that the punching sheet carried on it can be separated and taken out later, thereby facilitating the subsequent processing of the punching sheet.

[0042] See also Figure 6-7 An ultra-thin silicon steel sheet punching device includes a lifting structure 102, the lifting structure 102 includes a flat tube 1021, a telescopic tube 1022 is fixedly installed on the top of the flat tube 1021, and an elastic rubber surface 1023 is fixedly installed on the side of the flat tube 1021;

[0044] See also Figure 6-9 A device for punching ultra-thin silicon steel sheets includes a pulling structure 106, which includes a short plate 1061. A telescopic sleeve 1062 is fixedly installed on the top of the short plate 1061. A second electromagnet 1063 is fixedly installed on the top of the telescopic sleeve 1062.

A contact block 1066 is fixedly installed on the bottom end of the elastic rope 1065. A transmission belt 1067 is fixedly installed on the bottom end of the second electromagnet 1063.

[0045] In this embodiment, it should be noted that the short plate 1061 is fixedly installed on the side of the collection chamber 91, the telescopic sleeve 1062 is multi-stage telescopic, the top magnetic pole of the second electromagnet 1063 is attracted to the magnetic pole at the bottom end of the first permanent magnet 105, the contact block 1066 is a telescopic structure and the bottom end is fixedly installed in the top end of the bottom box 101, the contact block 1066 is provided with an inclined surface at the top end facing the grinding component 9, and the position of the inclined surface corresponds to the position where the supporting structure 93 extends out of the collection chamber 91, the transmission belt 1067 is wound on the guide wheel 96 and one end is fixedly connected to one side of the supporting structure 93, and the transmission belt 1067 is initially The state is relaxed, and the initial state of the elastic rope 1065 is stretched and taut. In this way, when the support plate 104 moves up, the magnetic attraction of the first permanent magnet 105 to the second electromagnet 1063 will be used to pull the support plate 104 to rotate, and at the same time the negative pressure generating device will stop running, causing the punching sheet carried on the top of the support plate 104 to slide to the side of rotation. At this time, the supporting short plate 933 will extend out of one side of the partition 931, and the silicon steel sheet falling from the top will be supported by the supporting short plate 933, and the polished silicon steel sheet stored in the collection chamber 91 will be discharged from the side discharge port of the collection chamber 91 at this time, thereby making room for the bottom.

[0046] Working principle: the steel plate raw material is fed into the bottom of the pressing plate 5, and then the hydraulic rod 4 is started to drive the pressing plate 5 to move downward, thereby pushing the pressing rod 82 to compress the oil inside the central tube 81, causing the oil inside the bottom box 101 to expand, thereby increasing the oil inside the jacking structure 102 to push its top to expand, thereby jacking up the support plate 104, and the support plate 104 is jacked up to the bottom end of the conveying plate 6 to receive the silicon steel sheet punched down by the upper pressing plate 5. At this time, the negative pressure generating device at the bottom generates negative pressure through the air guide tube to generate negative pressure suction at the top of the support plate 104, thereby adsorbing the silicon steel sheet, and then the pressing plate 5 moves up, and the support plate 104 will automatically move down at the same time. During the next stamping, the support plate 104 will move up again according to the above steps. At this time, the first permanent magnet 105 and the second electromagnet 1063 are attracted to each other, and then the support plate 104 will be pulled to rotate during the upward movement. The upward movement of the support plate 104 will pull the pulling structure 106 upward, and synchronously pull the supporting structure 93 to move horizontally. At the same time, the negative pressure generating device stops, and the silicon steel sheet will fall onto the slot 932. Then, after continuing to move upward, the first permanent magnet 105 and the second electromagnet 1063 will be separated. Under the action of the spring 937, the supporting structure 93 will automatically rebound as a whole. Then, with the help of the micromotor electric grinding wheel 95, the silicon steel sheet will be polished and discharged from the discharge port on the side of the collection chamber 91 after the next horizontal movement. The silicon steel sheet is stamped and polished synchronously in this way.
