Description

Forming die and process for U-shaped pressure relief separation guard plate reinforced by multiple T-shaped ring ribs Technical Field The invention relates to the technical field of composite material molding, in particular to a molding die and a process for a plurality of U-shaped pressure relief separation guard plates reinforced by T-shaped ring ribs. Background The U-shaped pressure relief separation guard plate with the reinforced multi-T-shaped ring rib is divided into a metal stainless steel material and a composite material, the weight of the metal U-shaped pressure relief separation guard plate is four times that of the composite material, and the metal processing is used because the ring rib is provided with a complicated special-shaped surface, so that the processing amount of the product is huge in task amount and higher in cost. The traditional forming method of the U-shaped pressure relief separation guard plate of the composite material comprises the following three modes of metal direct processing, split forming and gluing assembly of the composite material and split forming and bolting assembly of the composite material. Firstly, preparing a U-shaped main body part and a circumferential T-shaped reinforcing rib by a split molding method, and then splicing the U-shaped main body part and the circumferential T-shaped reinforcing rib by a cementing connection or rivet connection method. Specifically: (1) The U-shaped pressure relief separation guard plate is made of metal steel, the overall weight of the pressure relief separation guard plate is increased, in addition, the U-shaped pressure relief separation guard plate is reinforced by adopting thin-wall outer circumferential reinforcing ribs, the structure of the U-shaped pressure relief separation guard plate is complex, the processing difficulty is high, the processing time is long, the cost is high, the U-shaped pressure relief separation guard plate is required to be processed by using a whole raw material, most of the raw material is processed, the raw material utilization rate is low, the cost is high, the manual manufacturing cost and the material manufacturing cost of a U-shaped pressure relief separation guard plate product can be obviously increased in the manufacturing process, and the U-shaped pressure relief separation guard plate is not suitable for manufacturing products in batch production. (2) The split forming and gluing assembly of the composite material has the main defects that the split forming mode of producing and manufacturing the U-shaped pressure release separation guard plate reinforced by the T-shaped ring ribs of the composite material is adopted in the prior art, but parts are needed to be formed firstly, then the U-shaped pressure release separation guard plate main body and the plurality of ring-shaped T-shaped reinforcing ribs are glued and connected through structural glue, and the glue is easy to break due to obvious interfaces between the glue interfaces of the U-shaped main body and the multi-ring-shaped T-shaped reinforcing ribs of the composite material under the action of external increased stretching or shearing load. (3) The split forming bolting assembly of the composite material has the main defects that the U-shaped main body and the annular T-shaped reinforcing ribs of the composite material are connected through bolts because the U-shaped main body and the annular T-shaped reinforcing ribs of the composite material are connected through bolts, holes are required to be formed in each part of the composite material product body, the holes can break part of fibers in the composite material body, the integral structural strength of the product is affected, and the bearing capacity of the product is obviously reduced under the action of external large tensile or shearing load. The product manufactured by the process has poor stability and reliability, lower damage load, obviously increased manual manufacturing cost and material manufacturing cost in the manufacturing process, and is not suitable for the product manufacture of mass production. In order to solve the problems, it is especially necessary to develop a novel forming die and process for a plurality of U-shaped pressure relief separation guard plates reinforced by T-shaped ring ribs. Disclosure of Invention Aiming at the defects existing in the prior art, the invention aims to provide a forming die and a process for a plurality of U-shaped pressure relief separation guard plates reinforced by T-shaped ring ribs, which have the advantages of reasonable structural design, high overall strength, high use reliability, good stability, no post assembly process, greatly reduced production cost, suitability for mass production for manufacturing products, strong practicability and easy popularization and use. The forming die comprises a male die, an outer female die, an integral lateral pressurizing block, a reinforcing rib split pre-paving block an
