Description

Technical Field

[0001] The utility model relates to the technical field of concentric circular sheet forming, in particular to a concentric circular sheet forming device. Background Art

[0002] Concentric circular sheets are in the shape of circular gaskets. Common methods for obtaining concentric circular sheet products include cutting (wire cutting or laser cutting) and punching. When using the wire cutting method, the processing efficiency is relatively low. When punching, two stations are conventionally used to produce hollow circular sheets. The first station punches the center hole, and the second station punches the outer shape. However, when the circular sheet at the first station is transferred to the second station and punched again, its concentricity is not good, which easily causes the concentric circular sheet to deform. In addition, during processing, when the sheet-shaped coil is unrolled, the multi-quantity synchronous punching effect is not good. Utility Model Content

[0019] (3) Beneficial effects

[0020] Compared with the prior art, the concentric circular sheet forming device has the following beneficial effects:

[0021] 1. The utility model is provided with a hydraulic push rod. During use, the two telescopic ends of the hydraulic push rods are extended to push the fixed frame to move downward until the pressure plate contacts the unrolled material on the fixed seat, thereby pressing and fixing the material through the pressure plate, and the telescopic end of the hydraulic push rod is continuously extended, so that when the punching cylinder and the magnetic ring contact and press the raw material, the outer ring of the circular sheet is punched out by the outer circular punching knife, and the circular sheet is continuously pushed downward into the fixed hole, and the spring is driven to compress. When the circular sheet is continuously pressed downward and contacts and presses down the inner ring punching knife, the inner ring is punched out by the inner ring punching knife, and the miscellaneous materials punched out in the middle can be pushed into the inside of the insertion hole. By forming concentric circular sheets at one time, the concentricity of the circular sheets can be better guaranteed, and the synchronous mass production effect is good.

[0022] 2. The utility model is provided with an insert rod. After the punching is completed, the telescopic end of the hydraulic push rod is retracted and reset. Then, the center miscellaneous materials in the insertion hole are pushed downward by the insert rod. The magnetic ring can better adsorb and lift the iron and other magnetically attractive materials after forming. The concentric circular pieces adsorbed by the magnetic ring can be pushed downward by the cylinder. When the hydraulic push rod is reset, the fixed frame is driven to reset and lift by the pull rope and the guide plate. Therefore, during the lifting process, the pull rope can drive the guide plate to rotate. Therefore, when the blanking is pushed out by the insert rod and the cylinder, the formed concentric circular pieces and the center miscellaneous materials are guided outward by the guide plate and enter the interior of the receiving box.
