Device and process for hot-working forming of aviation transparent material

Abstract

The invention discloses a device for hot-working forming of an aviation transparent material. The device comprises a base, wherein a furnace body is fixedly arranged on the base; the furnace body comprises a heating chamber and a forming chamber which are in communication; a feeding and discharging platform is arranged at one end of the base; an electric heating mechanism is arranged in the heating chamber; a profiling mechanism is arranged in the forming chamber; two parallel guide rails are arranged on the base; a translation vehicle is arranged on the base, front chain wheel frames are arranged on the front end surface of the base; a front chain wheel is arranged on each front chain wheel frame; rear chain wheel frames are arranged on the rear end surface of the base; a rear chain wheelis arranged on each rear chain wheel frame; front chain wheels and rear chain wheel are sleeved by chains; a conveying driving mechanism used for driving the rear chain wheels to operate is arrangedat the rear end of the base; chains are close to the top part of the base; the front and rear ends of the translation vehicle are respectively provided with a traction block; traction blocks are closeto the top part of the base; and two ends of the chains are correspondingly connected with two traction blocks. The device provided by the invention can reduce a scald accident rate and potential safety hazards, and can improve production efficiency.

Description

technical field [0001] The invention relates to thermoforming processing equipment, in particular to a thermoforming equipment and process for aviation transparent materials. Background technique [0002] The molding process of aviation transparent materials belongs to the field of glass thermal processing technology. It uses a special heating furnace for thermal processing, heats and softens transparent raw materials, and then uses forming cast iron molds to pressurize. Wait for it to cool naturally at room temperature, and finally obtain a transparent material with the characteristic of hyperbolic curvature. This technology, also known as hot bending technology, is mainly used in the field of windshield manufacturing of aviation tools. [0003] At present, during the thermoforming operation of aviation transparent materials, four flat transparent raw materials are stacked together, supplemented by high-temperature cotton to cover the surface of the material, and then plac...

AI Technical Summary

Problems solved by technology

[0004] 1. The lifting mechanism of the existing forming furnace equipment has not been fully automated, and manual operation is required when pressing the furnace, and the height of the pressing furnace is monitored by visual inspection

This method is relatively primitive, which increases the technical difficulty of the operation and also affects the accuracy of the furnace;

[0005] 2. The production of existing equipment requires natural cooling for cooling, so the processing time is as long as 48 hours, and the production efficiency is relatively low;

[0006] 3. The circuit laying is unreasonable, and the performance of the wire material is not the best

Once there is an abnormal situation, there will be hidden dangers of accidents;

[0007] 4. The thickness of the insulation cotton is not enough, and the insulation effect is not very good;

[0008] 5. The components of the furnace wire roller, lifting mechanism and other parts are often installed in a fixed connection, which is not conducive to the convenience of maintenance;

[0009] 6. The transmission iron chain is set too high above the operator's ankle, which is prone to burn accidents;

[0010] 7. The space in the furnace is not large enough, which is not conducive to the processing of aviation wide-body transparent materials;

[0011] 8. The observation window is a glass window type, and the glass window is often cracked due to excessive temperature, and the heat in the furnace is also dissipated as a result.
