Problems solved by technology

The more honeycomb structures used in the honeycomb chassis, the profiles need to be glued together, which takes time to assemble and increases the manufacturing cost.
The glue has a certain thickness, which will lead to an increase in wall thickness and an increase in the dimensional error of the entire chassis

Embodiment Construction

[0018] refer to Figure 1-Figure 4 As shown, in this embodiment, a thin-walled manufacturing process of a honeycomb chassis is characterized in that the process includes the following steps:

[0019] This process adopts a die-casting process, and sixty-four hexagonal thin-walled honeycomb structures 1 can be die-casted each time.

[0020] The transition fillet 2 can increase the strength of the honeycomb chassis and meet the production process requirements during die-casting, and the entire thin-walled honeycomb structure is demoulded by the ejector pin at this fillet.

[0021] The workpiece produced by die-casting will be heavier than the mass of profile extrusion. To solve this problem, double-sided drafting is used. The drafting end point 7 is in the middle of the hexagonal thin-walled honeycomb structure, and the drafting is carried out from the upper end surface and the lower end surface to the middle part at the same time, forming a special honeycomb structure with a th...

Abstract

The invention provides a manufacturing technique for a honeycomb chassis thin wall. Sixty-four hexogen thin-walled honeycomb structures can be die-cast at a time. By adopting the technique for producing the honeycomb chassis cast structures, the cost can be reduced, the production period of honeycomb chasses is shortened, the size and assembling precision of the whole honeycomb chasses can be improved, connection is reliable, and the safety performance is better guaranteed. Through transition circular corners, the strength of the honeycomb chassis can be improved, and the production technique requirements during casting can be met. The whole honeycomb chassis cast structures are subjected to demolding by jacking the circular corners through ejector rods. The mass of workpieces produced through casting is lower than that of workpieces subjected to profile extrusion, and in order to solve the problem, two-sided die pulling is adopted. Due to the fact that the casting technique is adopted, the thin wall thickness at the joints of the outer walls of honeycombs can be adjusted according to the actual thickness, the thin wall thickness of the whole honeycomb chassis are the same after combination is completed, errors of the thin-walled honeycomb structures in the combination process are reduced, and later recombination and maintenance of the thin-walled honeycomb structures are facilitated.

Description

technical field [0001] The invention belongs to the technical field of die casting, and relates to a thin-walled manufacturing process of a honeycomb chassis. Background technique [0002] The honeycomb chassis is a new type of automobile chassis. This invention mainly introduces a thin-walled manufacturing process of the honeycomb chassis. [0003] At present, the manufacturing process of the thin wall of the honeycomb chassis is processed by the traditional profile extrusion process. Profile extrusion is easy to have indentation, and the precision of the extruded honeycomb profile is not high. A profile can extrude up to four honeycomb structures at a time. The more honeycomb structures used in the honeycomb chassis require the use of glue between the profiles, the assembly is time-consuming and the manufacturing cost increases. The glue has a certain thickness, which will increase the wall thickness and increase the dimensional error of the entire chassis. [0004] Ba...
