Bent glass hot pressing furnace

Abstract

The invention discloses a bent glass hot pressing furnace. The bent glass hot pressing furnace comprises a furnace body, a control cabinet and a hearth, wherein the furnace body and the control cabinet are integrated; the furnace body comprises a thermos-technical structure and a mechanical frame structure; the bottoms of the furnace body and the control cabinets are connected with a base; the hearth is formed in the furnace body; an inner cavity air flue is formed in the side wall of the hearth; a furnace door is arranged on the front plate surface of the furnace body; the furnace door is connected with the furnace body through a connection rotation shaft; a control panel is arranged on the control cabinet. According to the bent glass hot pressing furnace, a heated air circulation principle is adopted, so that the uniformity of the temperature is greatly improved; the inner cavity of the hearth is all made of a vapor-resistant and anti-corrosion nichrome alloy plate; a temperature control instrument selects SHIMADEN FP series intelligent program temperature control instrument to control the temperature, so that the sintering requirement for storing multiple multi-section process curves is met; the furnace has a P.I.D parameter self-adjusting parameter and a manual revising function, and has an alarm protection function for outage such as overheat, insufficient temperature andaccident breakage.

Description

technical field [0001] The invention relates to the technical field of industrial automation, in particular to a curved glass hot-press furnace. Background technique [0002] Curved glass has the characteristics of light and thin, transparent and clean, anti-fingerprint, anti-glare, hard, scratch-resistant, and good weather resistance. It has been widely used in high-end smartphones and tablet computers, wearable devices, dashboards, and industrial computers. The panel protection glass of end products and the forming of curved glass are in the category of thermal processing, so hot-press furnaces are required for production. The working principle is usually preheating-forming-cooling. [0003] However, the existing equipment still has many deficiencies in the working process. First, when heating, the uniformity of the temperature is poor, so that the uniformity of the temperature field in the effective area cannot meet the requirements. Second, the preheating efficiency is l...

AI Technical Summary

Problems solved by technology

[0003] However, the existing equipment still has many deficiencies in the working process. First, when heating, the uniformity of the temperature is poor, so that the uniformity of the temperature field in the effective area cannot meet the requirements. Second, the preheating efficiency is low and the production It takes a lot of time; internal parts are easy to oxidize under high temperature environment; thirdly, the inner cavity of the furnace is easily corroded, which affects the service life of the equipment; fourthly, intelligent temperature control cannot be carried out, which cannot meet the sintering requirements for storing multiple multi-stage process curves , Fifth, it is not easy to disassemble or assemble, and the equipment will be unstable when the whole machine is running
