A method of manufacturing an integrated refrigerated compartment

Abstract

The invention provides a method for manufacturing an integral refrigerated carriage, which includes the following steps: A. cutting the cowl into shape according to the template of the outer contour of the cowl and installing it at the front end of the carriage; Fittings and skirt panels; C install the inner contour positioning limiter on the front wall according to the inner contour template of the front wall; D install limit blocks on both sides of the compartment; E install the left and right sides of the overall inner panel and A reinforced insulation layer is compounded in the roof area; F bends the overall inner panel into an arch shape, and pushes it into the passenger compartment to fix it; G installs a molding mold to form a cavity between the passenger compartment and the overall inner panel; H Polyurethane raw materials are injected into the mold cavity to form an integral structure of the insulation layer of the refrigerated compartment; I install the prefabricated rear sealing plate and rear door; J the front wall and rear sealing plate and the overall inner panel are sealed and waterproofed. The invention has high inner space utilization rate, easy control of molding size standard, simplified manufacturing process and improved manufacturing efficiency.

Description

technical field [0001] The invention relates to the technical field of refrigerated carriages, in particular to a method for manufacturing an integral refrigerated carriage. Background technique [0002] At present, the irregular refrigerated carriages in the domestic market mainly use six flat composite panels to assemble and combine in the original carriages, and then use profiles to fasten and form the corners. The bottom panel, top panel, left side panel, right side panel, front sealing panel, and rear sealing panel (including the rear door) that make up the refrigerated compartment are all made of sandwich panels, and the panels need to be bonded with double-sided panels and more glue , the amount of material used is large, the manufacturing cycle is long, the cost is high, the panels of each compartment are poorly bonded to the original compartment surface, the loading space is wasted, and the phenomenon of cold leakage is serious; another way is to make a refrigerated...

AI Technical Summary

Problems solved by technology

The bottom panel, top panel, left side panel, right side panel, front sealing panel, and rear sealing panel (including the rear door) that make up the refrigerated compartment are all made of sandwich panels, and the panels need to be bonded with double-sided panels and more glue , the amount of material used is large, the manufacturing cycle is long, the cost is high, the panels of each compartment are poorly bonded to the original compartment surface, the loading space is wasted, and the phenomenon of cold leakage is serious; another way is to make a refrigerated compartment first, and the overall Put it into the passenger vehicle and fix it, but there is also the problem that the refrigerated car is heavy and difficult to operate, and the space is small. The space utilization rate in the passenger car is low and the space is wasted.
