Quenching machining tool for heat treatment and cooling for track plate

Abstract

The invention relates to a device for performing quenching to a track plate, in particular to a quenching machining tool for heat treatment and cooling for a track plate. The quenching machining tool is invented and mainly aims to solve the problems of large deformation, uneven hardness and soft spots existing in the track plate since the track plate discharged from the furnace is put into the circulating water for quenching at present. The quenching machining tool comprises a box body, wherein a water drain pipe is arranged at the lower part of the box body, lower driving rollers are respectively installed at the upper part of the box body, all the lower driving rollers are connected through chains, lower water spray nozzles are respectively arranged among all the lower driving rollers, an upper driving roller bracket above the lower driving rollers is connected with an upper beam positioned above the upper driving roller bracket through a connecting rod in a sliding manner, a compression spring is arranged on the connecting rod, the upper beam is connected with a tool body through a leading screw, the tool body is fixedly connected with the box body, upper driving rollers are arranged below the upper driving roller bracket, all the upper driving rollers are connected through chains, upper water spray nozzles are respectively arranged among all the upper driving rollers, and the upper water spray nozzles and the lower water spray nozzles are respectively connected with a high pressure water pump respectively through pipelines; and an upper main driving roller on the right side and a lower main driving roller on the left side are connected with a speed reducer respectively through chains. The quenching machining tool has the advantages of small heat treatment deformation, even hardness and no soft spot.

Description

Technical field: [0001] The invention relates to a device for heat-treating, cooling and quenching crawler shoes hanging out of a furnace. Background technique: [0002] The method of carrying out heat treatment cooling and quenching to the crawler shoes that come out of the furnace at present is to drop the crawler shoes out of the furnace into the water tank of the circulation device. Disadvantages are: because the way of crawler shoes entering the water is not easy to control, so the deformation is relatively large, and 80% of the workpieces need to be re-aligned; the track shoes take a long and inconsistent time from being out of the furnace to entering the water, and the water temperature is unstable. The distribution is slow, and the hardness is often uneven, and there are soft spots. Invention content: [0003] The technical problem to be solved by the present invention is to provide a track shoe heat treatment cooling quenching machine tool with small deformation,...
