Description

Technical Field

[0001] The present invention relates to the technical field of rupture disc production, and particularly relates to a forming device and a forming method for an alligator tooth type rupture disc bracket. Background Art

[0002] A rupture disc is a pressure relief safety device driven by pressure difference, which is used to prevent equipment damage, ensure personal safety, and avoid property losses. The reverse-arch alligator tooth type rupture disc is a structural type of rupture disc, which is composed of a strength diaphragm and an alligator tooth disc. The strength diaphragm is a pressure-sensitive element, and the alligator tooth disc is a rupture-causing element. When the convex surface of the strength diaphragm is compressed by pressure to a certain extent and loses stability as a whole, it is cut by the alligator teeth of the alligator tooth disc during flipping to relieve pressure.

[0003] In the current processing method of alligator tooth discs, usually a circular blank is first stamped into an arch shape by a stamping die, and then the die is replaced, and the circular blank is punched into an alligator tooth shape by a punching die. The whole process is rather troublesome, especially when the diameter is large, it is more troublesome to replace the die, time-consuming and laborious, with low efficiency and high labor intensity. In addition, when punching the alligator tooth disc with a punching die, since the alligator tooth disc usually has a certain arc, when punching, the arch surface will also be pulled off together with the punching tool, resulting in the out-of-roundness of the finished alligator tooth disc and affecting the effect of the rupture disc. In view of the above defects, it is necessary to design a forming device for an alligator tooth type rupture disc bracket. Summary of the Invention

[0004] The purpose of the present invention is to provide a forming device for an alligator tooth type rupture disc bracket to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A forming method for an alligator tooth type rupture disc bracket includes the following steps:

[0006] Step 1: Place the circular blank in the circular groove, and push the pressing plate downward by a hydraulic cylinder, and the upper die also moves downward accordingly, so that the upper die and the lower die are closed, and the middle part of the circular blank in the circular groove is stamped into an arch shape by the arc-shaped convex block cooperating with the bearing block;

[0007] Step 2: The hydraulic cylinder continues to push the pressing plate downward, and the upper die and the upper wedge block also move downward accordingly. The second spring between the upper die base and the upper die is compressed. The upper wedge block pushes the lower wedge block to move, and the reset slider also moves along. At this time, the first spring is compressed. The lower wedge block pushes the wedge-shaped top block upward, and the punching cutter also moves upward accordingly. The punching cutter cooperates with the pressure-bearing block to punch the arch of the circular blank, thereby punching the middle part of the circular blank into a U shape and punching the arch edge of the circular blank into an alligator tooth shape, realizing the forming of the alligator tooth type bursting disc bracket. The part of the arch edge that is not punched by the punching cutter remains arched under the action of the arc-shaped convex block and the circular groove, so that the part of the arch edge of the alligator tooth type bursting disc bracket that is not punched does not lose its roundness.

[0008] Step 3: The hydraulic cylinder is used to push the pressing plate upward, and the upper wedge block moves upward away from the lower wedge block. Under the action of the elastic force of the first spring, it pushes the reset slider to move. The reset slider drives the lower wedge block to move, and the lower wedge block drives the wedge-shaped top block to move downward, thereby driving the punching cutter to move downward for resetting.
