Description

A kind of quenching tank

The present invention relates to a kind of quenching apparatus, specifically for high temperature workpiece being carried out the quenching tank of cooling quenching.

In heat treatment industry, workpiece is required for carrying out quenching operation in quenching apparatus after the heat treatment, so that workpiece can possess the performance that some are special, meets the needs used.At present, modal a kind of quenching apparatus is exactly quenching tank, quenching tank is used to carry out quenching operation, it is exactly that hardening media (such as water, quenching wet goods) is put into quenching tank, again workpiece to be quenched is immersed in hardening media, control the temperature of hardening media, make workpiece to be quenched fulfil assignment equably with rational chilling temperature.Having a wire basket in traditional quenching tank, need operator to be put in wire basket by workpiece to be quenched during operation, the hardening media that then wire basket is manually put into quenching tank again quenches.This mode, manually places workpiece and wire basket due to needs, and it is inefficient, and is susceptible to security incident.

The problem to be solved in the present invention is to provide a kind of quenching tank, adopts this quenching tank, can mechanically complete workpiece and the operation of hanging basket dip quench medium, decrease manual work, it is provided that work efficiency, and reduce potential safety hazard.

For solving the problems referred to above, take below scheme:

The quenching tank of the present invention includes cell body, and the side of cell body inwall has and adds heat pipe, adds heat pipe and arranges in continuous print S shape from top to bottom, and its two ends respectively steam inlet and steam (vapor) outlet.Being characterized in that there is the support of a shape in the outside of described cell body, cell body is positioned at the lower section of rack beam.The crossbeam of described support has motor, the column of support both sides all has chain-wheel mechanism, motor can control two chain-wheel mechanisms and move up and down along bracket upright post.Having crane on described support, crane hangs with hanging basket, the two ends of crane are connected in fixing with the chain-wheel mechanism of support two heel post respectively.

Further improvement of the present invention scheme is the top of described support two heel post and fixed chain wheels is all arranged at bottom, and same column top is connected by chain with the fixed chain wheels of bottom.The outfan of described motor is all connected with the fixed chain wheels on support two heel post top so that these two fixed chain wheels can constant velocity rotation in the same direction.All having lift truck on the column of described support both sides, lift truck is fixed on the chain between corresponding two fixed chain wheels so that when fixed chain wheels rotates, lift truck can move up and down along bracket upright post.The two ends of described crane are connected in fixing with the lifting workshop on support two heel post respectively.Described lift truck includes vehicle frame, and vehicle frame has directive wheel and two pair rollers.Described two pair rollers lay respectively at the both sides of bracket upright post, and on non-two opposite faces not abutting against bracket upright post of this two pair roller.The axis of described directive wheel and the axis perpendicular of two pair rollers, and directive wheel abuts against on the side of bracket upright post.Described vehicle frame is fixed on the chain between corresponding two fixed chain wheels so that fixed chain wheels can drive lift truck to slide up and down along bracket upright post when rotating.

In such scheme, described hanging basket is made of metal, and its latter half is cube structure, and the first half is ridge.There is hook at ridge two, the first half top, is hung on crane.There is opening a described hanging basket side parallel with portal trestle.

In such scheme, described hanging basket is made of metal, and its latter half is cube structure, and the first half is ridge.There is hook at ridge two, the first half top, is hung on crane.There is opening a described hanging basket side parallel with portal trestle.

Take such scheme, have the advantage that

Owing to there is the support of a shape in the outside of a kind of quenching tank of the present invention, the crossbeam of support having motor, the chain-wheel mechanism that this motor can control on support two column moves up and down, and has crane between two chain-wheel mechanisms, and crane hangs with hanging basket.Therefore, after being sling by hanging basket by crane, then workpiece to be quenched is put into hanging basket, then again through crane, hanging basket is put down, make in workpiece dip quench medium, it is possible to complete quenching operation.Hanging basket is sling after completing by operation again by crane, it is possible to taken out by workpiece easily.This employing mechanical system carries out picking and placeing the operation of workpiece and hanging basket, can reduce manual work, it is provided that work efficiency, can reduce the potential safety hazard of manual work simultaneously.

Fig. 1 is the structural representation of the quenching tank of the present invention；

As shown in Figure 1, the quenching tank of the present invention includes cell body 1, and the side of cell body 1 inwall has and adds heat pipe 2, adds heat pipe 2 and arranges in continuous print S shape from top to bottom, and its two ends respectively steam inlet and steam (vapor) outlet, steam inlet and steam (vapor) outlet all stretch out from the peristome of cell body 1.There is the support 3 of a shape in the outside of described cell body 1, and cell body 1 is positioned at the lower section of support 3 crossbeam.The crossbeam of support 3 there are motor 6, the top of 3 liang of heel posts of support and bottom all have the fixed chain wheels 7 of fixed chain wheels 7, same column top and bottom to be connected by chain 8.The outfan of motor 6 is all connected with the fixed chain wheels 7 on 3 liang of heel post tops of support so that these two fixed chain wheels 7 can constant velocity rotation in the same direction.All having lift truck 9 on the column of described support 3 both sides, lift truck 9 includes vehicle frame, and vehicle frame has directive wheel and two pair rollers.Described two pair rollers lay respectively at the both sides of support 3 column, and on non-two opposite faces not abutting against support 3 column of this two pair roller.The axis of directive wheel and the axis perpendicular of two pair rollers, and directive wheel abuts against on the side of support 3 column.Described vehicle frame is fixed on the chain 8 between corresponding two fixed chain wheels 7 so that lift truck 9 can be driven when fixed chain wheels 7 rotates to slide up and down along support 3 column.Having crane 5 on described support 3, crane 5 hangs with hanging basket 4, the two ends of crane 5 are connected in fixing with between the lift truck 9 on 3 liang of heel posts of support respectively.

Wherein, described hanging basket 4 is made of metal, and its latter half is cube structure, and the first half is ridge.There is hook at ridge two, the first half top, is hung on crane 5.There is opening hanging basket 4 side parallel with portal trestle 3.So, when hanging basket 4 rises, workpiece to be quenched only need to be transported to by hanging basket 4 by operator with dolly, and workpiece is directly poured into hanging basket 4.

During operation, first drive motor 6 works, and makes lift truck 9 increase along support 3 column, drives crane 5 and hanging basket 4 to rise simultaneously, and workpiece to be quenched is put into by operator from hanging basket 4 opening part；Then, motor 6 reverse drive, make lift truck 9, crane 5 and hanging basket 4 decline, until the workpiece in hanging basket 4 is fully immersed in quenching liquid；After having quenched, then make hanging basket 4 rise after, workpiece can be taken out.Adding logical steam in heat pipe 2 in quenching tank, being in order to quenching liquid is heated, it is prevented that quenching liquid temperature is too low, after causing workpiece quenching, intensity is not enough and be unable to reach instructions for use.
