Automobile fuel tank fixed steel belt multi-station progressive die

Abstract

The invention discloses a multi-station progressive mold for fixing a steel belt of an automobile fuel tank, which belongs to the technical field of moulds, and includes an upper mold frame assembly, a lower mold frame assembly, a convex shell assembly, a trimming assembly, a bending assembly, and a cutting assembly , material guide assembly and unloading assembly; the material guide assembly is set on the side of the lower mold base assembly; the lower mold base assembly is provided with a die insert; the pressing convex package assembly, trimming assembly, bending assembly, and cutting assembly are located on On the die insert, and distributed sequentially along the material guide direction; the unloading assembly is arranged between the upper mold base assembly and the lower mold base assembly, and the two sides are symmetrically distributed; the trimming assembly, bending assembly, and cutting assembly are fixed on the Between the upper mold base assembly and the unloading assembly; between the upper mold base assembly and the lower mold base assembly are connected through a guide sleeve guide column assembly and a lifting device. The invention realizes the combination of multiple processes by optimizing the structural design, and has the characteristics of reasonable design, low production cost, high processing precision, high production efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a multi-station progressive mold for fixing steel belts of automobile fuel tanks. Background technique [0002] The automobile fuel tank is fixed under the automobile chassis, the upper surface is in contact with the automobile chassis through the shock absorber, and the lower surface is suspended. And when the car is running, the impact on the fuel tank due to acceleration, deceleration and turning is very large, and the volume of the fuel tank is tens of liters or even more than one hundred liters, so the weight of the fuel tank also reaches tens of kilograms, so the choice of fixing method is also very important. becomes particularly important. Usually, the steel belt of the automobile fuel tank is used for fixing. [0003] The fixed steel belt of the automobile fuel tank usually needs to carry out convex hull pressing, edge trimming, bending and cutting during the processing ...

AI Technical Summary

Problems solved by technology

[0003] The fixed steel belt of the automobile fuel tank usually needs to carry out convex hull pressing, edge trimming, bending and cutting during the processing process. It usually requires multiple sets of single-process processing molds for multi-channel processing. The processing process is relatively complicated and the processing cycle is long. Production Low efficiency; at the same time, when multiple groups of molds are processed, repeated positioning is required, the processing accuracy is low, and the cost is high

[0004] At present, with the continuous acceleration of the industrialization process, most of the factory equipment is developed in the aspects of multi-functional integration, automation and intelligence. The original processing molds are far from meeting the current processing needs, resulting in production stagnation. Therefore, how to effectively Improving the integrated processing of the fixed steel belt of the automobile fuel tank has become a major problem currently facing
