Contact type heating forming process of SGP bottom protecting plate

Abstract

The invention relates to a contact type heating forming process of an SGP bottom protecting plate. The process comprises the following steps that 1, a fabric taking a PP glass fiber felt as a base material is preheated under the condition that the heating temperature is 190 + / - 10 DEG C and the heating time is 45 seconds; 2, after preheating is completed, the fabric is heated under the condition that the heating temperature is 230 + / -10 DEG C and the heating time arranged is 45 seconds; and 3, pressure molding is carried out on the fabric and cloth under the condition that the pressure of a press machine is 23 + / - 2 Mpa and the pressure maintaining time is 45 + / - 10 seconds to obtain the SGP bottom protecting plate. According to contact type heating forming process, an integrated forming scheme is provided, and the problems that a traditional bottom protecting plate is complex in machining process and complicated in operation process are solved; raw materials do not need to be pressedinto plates in the machining process, the fabric can be directly heated and finally subjected to the pressure forming; and meanwhile, the coupling of the materials is promoted through secondary heating on the fabric, the forming stiffness and the tensile property are improved, and the product forming percent of pass is improved.

Description

technical field [0001] The invention relates to a forming process of auto parts, in particular to a contact heating forming process of an SGP bottom guard plate. Background technique [0002] The main function of the car bottom guard is to protect the car engine, gearbox and the bottom pipelines from being scratched and broken by stones and other hard materials during driving, which will cause damage to auto parts and affect the driving safety of the car; the traditional car bottom guard Usually the material is made of conventional aluminum alloy material, which has low strength, is easy to deform, and is difficult to reset in case of collision, and has resonance phenomenon, which leads to the short service life of the bottom guard plate and high maintenance and replacement costs; the traditional car bottom guard plate cannot be formed at one time and requires Carry out bonding, press into boards, and finally heat the boards and press them to form. The above molding process ...

[0002] The main function of the car bottom guard is to protect the car engine, gearbox and the bottom pipelines from being scratched and broken by stones and other hard materials during driving, which will cause damage to auto parts and affect the driving safety of the car; the traditional car bottom guard Usually the material is made of conventional aluminum alloy material, which has low strength, is easy to deform, and is difficult to reset in case of collision, and has resonance phenomenon, which leads to the short service life of the bottom guard plate and high maintenance and replacement costs; the traditional car bottom guard plate cannot be formed at one time and requires Carry out bonding, press into boards, and finally heat the boards and press them into moldings. The above-mentioned molding process is cumbersome and inefficient. Therefore, the present invention proposes a SGP bottom guard plate contact heating molding process to solve the above problems
