Problems solved by technology

In the prior art, the types of diaphragms include metal diaphragms and non-metal diaphragms. Compared with metal diaphragms, non-metal diaphragms have the advantages of good flexibility, good deformation ability, good sealing performance and good fatigue resistance, but non-metal diaphragms Diaphragms are generally thin in thickness, difficult to form, prone to defects such as pores, uneven product thickness, and even partial perforation, which is not conducive to long-term storage of fuel or combustion aids

Abstract

The invention relates to a method for forming a non-metallic diaphragm of a storage tank. The molding method includes: providing raw materials, the raw materials include NX split pieces and a ring-shaped rib, wherein N is the number of second ribs, X is an integer, and the shape of the ring-shaped rib is consistent with that of the first rib; X sub-petal pieces are assembled into a fan-shaped assembly piece, and the side of the fan-shaped assembly piece has an overlapping portion; each assembled fan-shaped piece is spliced ​​on the surface of the die of the press mold according to the product structure of the non-metallic diaphragm, adjacent to each other. The lap joints of the radial sides of the two fan-shaped assembling pieces overlap to form the second reinforcing rib, and the inner lap joints of each fan-shaped assembling piece are covered with annular ribs; start the press, so that each sector-shaped assembling piece and the ring The shaped ribs are solidified and formed to form a formed non-metallic diaphragm; the press is turned on to demould the formed non-metallic diaphragm and process it into a finished non-metallic diaphragm. The invention improves the accuracy of the external dimension of the product, the appearance quality and the qualified rate of the product.

Description

technical field [0001] The invention belongs to the technical field of composite material forming, and in particular relates to a method for forming a non-metallic diaphragm of a storage tank. Background technique [0002] The storage tank generally has a built-in diaphragm to realize the discharge of fuel or oxidizer inside the storage tank. In the prior art, the types of diaphragms include metal diaphragms and non-metal diaphragms. Compared with metal diaphragms, non-metal diaphragms have the advantages of good flexibility, good deformation ability, good sealing performance and good fatigue resistance, but non-metal diaphragms Diaphragms are generally thinner, more difficult to form, prone to defects such as pores, uneven product thickness, and even partial perforation, which is not conducive to the long-term storage of fuel or combustion aids. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a me...
