Quenching device and quenching method for bearing seat production

Abstract

The invention discloses a quenching device and a quenching method for bearing seat production, specifically relates to the technical field of bearing processing, comprising a quenching box and eight vertical plates, the outer surface of the quenching box is provided with a thermal insulation frame, the The front of the thermal insulation frame communicates with one end of the first connecting pipe. The present invention adopts the driving assembly, the first gear, the second gear, the rotating storage plate, the first support wheel, the second support wheel, the connection pump, the heat preservation frame and the rotating blade, and the flowing liquid drives the rotating blade while impacting the rotating blade The second support wheel rotates, at this time the second support wheel drives the workpiece inside the quenching box to rotate, so that the workpiece rotates during the quenching process to ensure uniform quenching as a whole, and the workpiece can collect the heat overflowed from the quenching box for preheating before quenching, reducing heat waste Loss, and ensure that the workpiece is rotated during the quenching process, to ensure the uniformity of quenching and the performance of the workpiece after quenching, and to significantly improve the quenching effect of the workpiece while achieving environmental protection.

Description

technical field [0001] The invention relates to the technical field of bearing processing, and more specifically, the invention relates to a quenching device and a quenching method for bearing housing production. Background technique [0002] The quenching of steel is to heat the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), keep it warm for a period of time to make it fully or partially austenitized, and then cool it with a cooling rate greater than the critical cooling rate. A heat treatment process for rapid and rapid cooling below Ms (or isothermal near Ms) for martensite (or bainite) transformation. Usually, the solid solution treatment of aluminum alloy, copper alloy, titanium alloy, tempered glass and other materials or the heat treatment process with rapid cooling process is called quenching. [0003] For example, the Chinese patent (application number: CN201110074651.1) discloses a bearing-propelled s...

Problems solved by technology

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quenching device and a quenching method for the production of bearing housings. The technical problem to be solved by the present invention is: the bearing is not preheated during the quenching process, and the bearing is directly High-temperature quenching may cause a large temperature difference between the inside and outside of the bearing structure, resulting in the overall deformation or affecting the performance. At the same time, the bearing is not convenient to take and place during the quenching process. If the bearing is fixed at a certain position, the quenching of the bearing surface may occur The problem of uneven effect
