Title
(EN) HOLLOW BODY FORMING DIE AND HOLLOW BODY FORMING METHOD
(FR) MOULE DE FORMAGE DE CORPS CREUX ET PROCÉDÉ DE FORMAGE DE CORPS CREUX

Abstract
(EN)
Disclosed are a hollow body forming die and a hollow body forming method. The forming die comprises a left and a right half die (1), wherein the bottom of the left half die (1) is provided with a left avoidance groove (9), the bottom of the right half die (1) is provided with a right avoidance groove (9), a left bottom sliding block (2) is provided in the left avoidance groove (9), a right bottom sliding block (2) is provided in the right avoidance groove (9), and the left and right bottom sliding blocks (2) constitute a sliding block set. The design of the die solves the problem that a hollow body with a built-in component formed by an existing traditional process has a process hole. The hollow body forming method has the advantages of a short forming period, a high production efficiency, good combination between the built-in component and an inner wall of a fuel tank, and a high positional stability. According to the hollow body forming method, the process hole will not be formed, a subsequent procedure of welding a “cover cap” for sealing does not need to be added, and the method has the advantages of low emissions and low investment costs for equipment and personnel.
(FR)
La présente invention concerne un moule de formage de corps creux et un procédé de formage de corps creux. Le moule de formage comprend un demi-moule gauche et un demi-moule droit (1), le fond du demi-moule gauche (1) étant pourvu d'une rainure d'évitement gauche (9), le fond du demi-moule droit (1) étant pourvu d'une rainure d'évitement droite (9), un bloc coulissant inférieur gauche (2) étant disposé dans la rainure d'évitement gauche (9), un bloc coulissant inférieur droit (2) étant disposé dans la rainure d'évitement droite (9), et les blocs coulissants inférieurs gauche et droit (2) constituant un ensemble de blocs coulissants. La conception du moule résout le problème selon lequel un corps creux comprenant un composant intégré formé par un procédé traditionnel existant présente un trou de traitement. Le procédé de formage de corps creux a pour avantages une courte période de formage, un rendement de production élevé, une bonne combinaison entre le composant intégré et une paroi interne d'un réservoir de carburant, et une stabilité de position élevée. Selon le procédé de formage de corps creux, le trou de traitement n'est pas formé, une procédure ultérieure de soudage d'un "capuchon de couvercle" pour assurer une étanchéité n'a pas besoin d'être ajoutée, et le procédé a pour avantages de faibles émissions et de faibles coûts d'investissement en termes d'équipement et de personnel.
