Problems solved by technology

Therefore, the push-pull mechanism has the problems of inaccurate positioning and difficult decoupling
[0006] (2) During the process of rolling the tray into and out of the front and rear chambers, the heat treatment medium such as quenching oil is easy to adhere to the rollers, causing the feeding mechanism to slip, which may cause the workpiece to slip

Abstract

The invention provides a feeding system of a double-chamber vacuum furnace used for thermal treatment. The double-chamber vacuum furnace used for thermal treatment comprises a front chamber and a rear chamber and is characterized in that the feeding system comprises a drive transmission device and a rising and falling device, the drive transmission device is arranged in the front chamber, and the rising and falling device is arranged at the bottom of the rear chamber and extends into the rear chamber; and the drive transmission device is used for achieving circulation, between the front chamber and the rear chamber, of thermal treatment workpieces, and the rising and falling device is used for achieving rising and falling of the thermal treatment workpieces. Compared with the prior art, a body structure of the feeding system is located outside the rear chamber of the vacuum furnace, and therefore the feeding system can be away from a high-temperature environment, and the aging failure caused by thermal expansion is avoided.

Description

technical field [0001] The invention relates to a heat treatment device, in particular to a feeding system of a double-chamber vacuum furnace for heat treatment. Background technique [0002] Vacuum furnace is regarded as one of the equipments for upgrading equipment in the heat treatment industry. The important reason is that the product parts processed by vacuum furnace have bright surface, less oxidation, good performance and high precision. It is easy to realize energy saving, consumption reduction and reduction in the production and operation of vacuum furnace. It belongs to clean production equipment and meets the requirements of today's environmental protection. There are very few gas molecules in vacuum, and the free path of molecules becomes larger, so light rare metals, refractory metals, rare metals and other special alloy materials that cannot be obtained under normal pressure can be produced. [0003] The double-chamber vacuum furnace includes a front chamber a...
