Vertical high-frequency quenching machine

Abstract

The invention discloses a vertical high-frequency quenching machine which comprises a high-frequency quenching heating device, cooling liquid, a cooling oil tank, a portal machine frame, a working sliding table and a control system. A straight track is arranged on the portal machine frame, the working sliding table is installed on the straight track and controlled to move horizontally through a translation mechanism, a lifting mechanism is arranged on the working sliding table, a clamping mechanism is installed on the lifting mechanism, the clamping mechanism is driven by the lifting mechanism and moves vertically under the control of a servo motor, a quenching workpiece is clamped by the clamping mechanism and arrives at an induction coil to be quenched under the control effect of a control system, and the control system controls the quenching workpiece through a numerical control programming control method. The vertical high-frequency quenching machine has the advantages of being high in automation degree, reducing labor intensity of workers, improving productivity, guaranteeing safety of the workers, and being capable of obtaining good processing accuracy, good in repeatability and capable of guaranteeing quenching quality of the workpiece.

Description

technical field [0001] The invention relates to the technical field of quenching equipment, in particular to a vertical high-frequency quenching machine. Background technique [0002] Quenching process is widely used in modern machinery manufacturing industry. The important parts in machinery, especially the steel parts used in automobiles, airplanes and rockets, are almost all quenched. In order to meet the technical requirements of various parts, various quenching processes have been developed. For example, according to the part to be treated, there are overall, local quenching and surface quenching; according to whether the phase transformation is complete during heating, there are complete quenching and incomplete quenching (for hypoeutectoid steel, this method is also called subcritical quenching); according to cooling The content of time phase transformation includes graded quenching, austempering and underspeed quenching. [0003] For the quenching treatment of sha...

Problems solved by technology

Later people invented a rod quenching device, such as Chinese Patent No. 01107504.X, this technology can guarantee the quality of rod quenching, and has the advantage of saving energy, but this patented technology does not solve the problem of rod quenching operation. The movement in the process cannot reduce the labor intensity of workers, and cannot obtain good machining accuracy
