Gear hot-stamping equipment and gear hot-stamping method

Abstract

The invention discloses gear hot-stamping equipment which is used for machining gears through a hot-stamping method. The gear hot-stamping equipment comprises a heating system, a stamping die, as well as a quenching tank, a turnover box and a conveying system, wherein the heating system is used for heating a blank material; the stamping die is used for stamping the heated blank material into a gear; the turnover box comprises a downwardly-inclined sliding chute and is used for guiding the hot-stamped gear into the quenching tank through the downwardly-inclined sliding chute; a cooling medium is contained in the quenching tank and is used for quenching the stamped gear; and the conveying system comprises a servo motor and a grab mechanism, and the servo motor controls the grab mechanism to convey the heated blank material into the stamping die and convey the stamped gear into the turnover box. Compared with the prior art, due to the adoption of the gear hot-stamping equipment, the service life of the stamping die can be prolonged, the production resources are saved, the production efficiency is increased and the machining accuracy and the service life of the gear are ensured, and further, the automatic production can be realized through an intelligent control system. In addition, the invention further discloses a corresponding gear hot-stamping method.

Description

technical field [0001] The invention relates to stamping equipment and a gear stamping method, in particular to a hot stamping equipment for processing gears and a method for processing gears through a hot stamping process. Background technique [0002] The traditional processing methods of gears are generally divided into: gear hobbing, gear shaping, milling, shaving, grinding, planing, pulling, injection molding, cold stamping and other processing technologies. The precision is not high, and the tooth surface is rough; while the hot stamping processing gear can fully meet the requirements in terms of efficiency and gear accuracy; when the gear is cold stamping processing, it usually takes 3-4 processes to complete the stamping of a gear. There are very high requirements for strength. In order to change the above problems, the existing technicians have developed a new process based on the cold stamping process of gears: hot stamping process, this process is very suitable f...

Problems solved by technology

[0009] On the other hand, after the traditional gear stamping is completed, it is necessary to quench the stamped semi-finished gear. In order to improve production efficiency, existing technicians often store the stamped semi-finished product in a storage box after hot stamping. When the semi-finished products in the box accumulate to a certain amount, the stamped semi-finished products are transported to the quenching device by a grabbing mechanism such as a manipulator for heating and quenching, which greatly wastes production resources and has low production efficiency and complicated procedures.
