Continuous hot bending furnace for front windshield of large passenger car

Abstract

The invention relates to hot bending furnace equipment, in particular to a continuous hot bending furnace for large bus front windshield. The continuous hot bending furnace is in a circulated rectangular ring shape and comprises a plurality of heating chamber units, cooling chamber units, an upper piece ferry unit, a ferry channel unit, a glass car and an automatic control system, wherein the heating chamber units are transversely arranged side by side, the cooling chamber units are parallel to the heating chamber units, and the upper piece ferry unit and the ferry channel unit are arranged at the two ends of the heating chamber units and the cooling chamber units. The continuous hot bending furnace is reasonable in structural design and is of a rectangular circulated structure on the whole, a ferry carrier vehicle and a traction vehicle are matched for solving the turning problem in the circulated structure, turning movement can be stably and safely achieved, meanwhile, the traction vehicle is the running power of the whole system, the overall structure is reasonable in design, and operation control is convenient.

Description

technical field [0001] The invention relates to a hot bending furnace equipment, in particular to a continuous hot bending furnace for the front windshield of a large passenger car. Background technique [0002] At present, the hot bending furnace equipment for front windshield of large passenger cars mainly uses single-chamber, three-chamber, and four-chamber heating forming and cooling annealing. This equipment has economic problems such as large power consumption, high labor intensity, and low production efficiency. After the glass is formed, the heat preservation is unstable, the glass is easy to warp, the light is distorted, the glass is easy to break, and there are technical bottlenecks such as self-explosion. [0003] The glass car of the ground circulation continuous hot bending furnace needs to run horizontally and vertically, but the wheels of the glass car are fixed and run in one direction. If you want to change the running direction of the glass car, you need to...

AI Technical Summary

Problems solved by technology

Such a turntable has poor stability, excessive clearance, and increased maintenance

Affect product quality and production efficiency

[0004] At present, the glass car of the continuous hot bending furnace at home and abroad generally adopts the thermal insulation box car, and its disadvantage is that there are 800 mm high box covers around the glass car, which makes it very troublesome to load or unload the glass

The glass is easily broken during the glass sintering process, resulting in a large number of defective products and increasing the production cost
