Abstract

The utility model relates to a quenching machine tool for cooling a track plate after heat treatment, which is a device for the cooling quenching of the track plate. The quenching machine tool is designed to mainly solve the current problems of large deformation, non-uniform hardness, soft spots and the like of the track plate when the discharged track plate is put into circulating water to be quenched. The quenching machine tool for cooling the track plate after heat treatment comprises a cabinet; the lower part of the cabinet is provided with a drain pipe; the upper part of the cabinet is provided with lower driving rollers; the lower driving rollers are connected by a chain; lower spray nozzles are arranged among the lower driving rollers; an upper driving roller arranged above the lower driving rollers is in sliding connection with an upper beam positioned above the upper driving roller through a connecting rod; the connecting rod is provided with a compression spring; the upper beam is connected with the body of the machine tool by screws; the body of the machine tool is fixedly connected with the cabinet; the lower side of an upper driving roller frame is provided with the upper driving rollers; the upper driving rollers are connected by a chain; upper spray nozzles are arranged among the upper driving rollers; the upper spray nozzle and the lower spray nozzle are connected with a high-pressure pump by a pipeline; and the upper driving rollers at the right side and the lower driving rollers at the left side are respectively connected with a speed reducer by a chain. The quenching machine tool for cooling the track plate after heat treatment has the advantages of slight deformation, uniform hardness and no soft spot in the heat treatment.

Description

Quenching machining tool for heat treatment and cooling for track plate

Technical field:

The utility model relates to the device that a kind of grip-pad that one-tenth is hung up stove is heat-treated Cooling Quenching.

Background technology:

At present to heat-treat the method for Cooling Quenching be that the grip-pad that will come out of the stove drops in the tank of circulation device to the grip-pad that one-tenth is hung up stove.Shortcoming is: because grip-pad entry mode is wayward, so deformation ratio is bigger, and 80% workpiece needs alignment again; Grip-pad is long and inconsistent from the entry time of coming out of the stove, and the water temperature instability, accumulates in the tank after the workpiece entry, and heat distributes slowly, the hardness inequality often occurs, and the soft spots phenomenon is arranged.

Summary of the invention:

It is little that technical problem to be solved in the utility model provides a kind of grip-pad thermal treatment Cooling Quenching distortion, and hardness is even, no soft spots, the quenching machining tool for heat treatment and cooling for track plate that quality stability is good.

Above-mentioned purpose is achieved in that it comprises casing, lower box has water shoot to be connected with water reservoir by pipeline, several lower driving rollers are equipped with on casing top, several lower driving rollers connect with chain mutually, and all on a horizontal plane, become in-line to arrange, water jet all is housed down between each lower driving roller, there is last live roll frame the top of lower driving roller, and last live roll frame is slidingly connected by union lever and the upper beam that is positioned at its top, is set with compression spring on the union lever, upper beam is connected with lathe bed by leading screw, lathe bed is fixedlyed connected with casing, live roll on several is housed below the last live roll frame, and live roll connects with chain mutually on several, and all on a horizontal plane, become in-line to arrange, water jet all is housed between the live roll on each, on, following water jet all has pipeline to be connected with high-pressure hydraulic pump; Going up live roll near first of right side intake mechanism is last main drive roller, last main drive roller by chain be positioned at it near step-down gear on the lathe bed be connected, under this step-down gear drive, clockwise rotate during work; First lower driving roller in left side is following main drive roller, following main drive roller by chain be positioned at it near step-down gear on the lathe bed be connected, under this step-down gear drive, rotate counterclockwise during work.

The utility model has the advantages that: heat treatment deformation is little, and 100% workpiece does not need alignment; Hardness is even, no soft spots; Quality stability is good.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 be the utility model when installing and using with the annexation synoptic diagram of relevant auxiliary facility.

Embodiment:

With reference to Fig. 1, it comprises casing 11, lower box has water shoot 13 to be connected with water reservoir by pipeline, several lower driving rollers 10 are equipped with on casing top, several lower driving rollers connect with chain mutually, and all on a horizontal plane, become in-line to arrange, water jet 12 all is housed down between each lower driving roller, there is last live roll frame 5 top of lower driving roller, last live roll frame is slidingly connected by union lever 9 and the upper beam 3 that is positioned at its top, be set with compression spring 2 on the union lever, putting the beams in place is connected with lathe bed 6 by leading screw 8, and lathe bed is fixedlyed connected with casing, live roll 4 on several is housed below last live roll frame, live roll connects with chain mutually on several, and all on a horizontal plane, becomes in-line to arrange, water jet 7 all is housed between the live roll on each, on, following water jet all has pipeline to be connected with high-pressure hydraulic pump; Going up live roll near first of right side intake mechanism is last main drive roller, last main drive roller by chain be positioned at it near step-down gear 1 on the lathe bed be connected, under this step-down gear drive, clockwise rotate during work; First lower driving roller in left side is following main drive roller, following main drive roller by chain be positioned at it near step-down gear 1 on the lathe bed be connected, under this step-down gear drive, rotate counterclockwise during work.

Principle of work:

With reference to Fig. 2, on right side of the present utility model intake mechanism 16 is installed, conveyor 15 is installed in the left side, supply lead is connected with two step-down gears 1 respectively by two frequency transformers 14, during work, grip-pad 17 enters the utility model from the right side intake mechanism, the live roll of going up of the present utility model is clockwise rotated by the step-down gear drive, lower driving roller is driven by step-down gear and rotates counterclockwise, reach in the gap of adjusting live roll and lower driving roller before the cooling, the hydraulic pressure of following water jet, on, sewer line all is separately installed with under meter and tensimeter, and the step-down gear of live roll and lower driving roller can arbitrarily be adjusted the speed of travel of workpiece by Frequency Converter Control in the drive, workpiece in the process of walking, on, following water jet is sprayed water simultaneously, and fully cooling under the strong spray of high pressure water is sent into tempering stove by conveyor after cooling is finished.
