Description
Technical field：
The invention belongs to quenching technique field, it is related to a kind of quenching cooler, particularly a kind of Continuous Roller bottom
The automation cooling device of stove Quenching Production Line.
Background technology：
Quenching is that metal works are heated into austenitizing temperature and held for some time, then with more than critical cooling speed
Degree cooling, to obtain non-diffusing type transformation tissue, such as Technology for Heating Processing of martensite, bainite or austenite.Quenching cooling
It is the process that the workpiece after heating is carried out quick cooling, it is most important to structural transformation and performance needed for acquisition.To realize
The quenching cooling of metal works, reaches required tissue and performance, while avoiding workpiece to ftracture and become in cooling procedure again
The selection of shape, wherein quenching and cooling method and device is most important.Quenching unit is a container filled with hardening media, wherein
Hardening media can be water, oil, fused salt and various water-soluble quenching liquids etc..In order to realize the uniform cooling of workpiece, obtain more preferable
Quenching effect, needed in quenching unit be equipped with temperature control system and the hardening media circulatory system, for controlling hardening media
Temperature and flowing.
The charging of continous way heat-treatment production line workpiece typically has continuous feed and cycle charging two ways, used as charging
Carrier have two kinds of forms of net belt type and roller-bottom type, using guipure as carrier, cycle charging uses carrying roller conduct for continuous feed
Carrier.Net belt type production line workpiece is lain on guipure, and the size and quality according to workpiece can keep flat, it is also possible to stack, and is folded
The number of plies put is according to the capacity of equipment and the size of workpiece and quality, generally 2~4 layers.The characteristics of net belt type feeding is：Plus
Workpiece after heat is fallen into cooling device by freely falling body mode, and cooling medium, the bottom of cooling device are filled with cooling device
Portion arranges net belt type elevator, and workpiece is cooled down during freely falling body, fallen on guipure after cooling, and Jie is lifted out by elevator
Matter liquid level；But the workpiece after heating falls into cooling medium in freely falling body form, and cooling procedure is uncontrolled, and workpiece freedom
Falling bodies are also easy to produce to touch and knock and lose, and the product of different batches cannot be distinguished clearly, and the product for different batches is, it is necessary to pass through
Time enters between-line spacing, it reduces production efficiency.Roller-bottom type production line by carrying roller size due to being limited, and big-and-middle-sized workpiece is direct
Lie on carrying roller, and small-sized, miniature parts are typically placed in charging basket, charging basket is lain on carrying roller, prevents workpiece from dropping,
Substantial amounts of carrying roller is arranged between heating furnace and quenching unit, workpiece is moved on carrying roller, wherein being arranged in the portion of quenching unit
Divide carrying roller, can move up and down, after workpiece after heating is moved on the carrying roller of quenching unit, carrying roller declines, and falls into cooling
Below medium liquid level, the cooling of workpiece is realized, carrying roller rises after cooling, depart from cooling medium, by workpiece transfer to next station；
Although the part carrying roller of existing roller-bottom type heat-treatment production line cooling device can be with raising and lowering, its cooling system all compares
Simply, agitator is usually installed in cooling device, because the production capacity of continous way heat-treatment lines is big, cooling device compared with
Greatly, the capacity of cooling medium is larger, and the mixing effect of agitator is limited, and the mobility and temperature homogeneity of cooling medium are poor,
Mixing direction also can only be mode from bottom to top, it is impossible to three-dimensional stirring is formed in quenching tank, therefore, quench cooling effect
Not good, surrounding particularly on quenching bench, because red-hot workpiece is cooled down, can form local temperature field higher, reduce cooling
The cooling performance of medium, it is impossible to realize different zones uniform temperature fields, so as to cause the cooling of upper strata part undesirable, influences work
The structure property of part.Therefore, seek to design a kind of quenching cooler, set that speed is adjustable can move up and down in quenching tank
Quenching bench jacking system, accelerate cooling velocity, and make cooling procedure controllable；In quenching tank inner bottom part, medium circulation dress is set
Put, realize flow, pressure, the control of flow direction of cooling medium, realize cooling uniformity, improve product thermal treatment quality；Setting
Put quenching tank top and blowing-down device is set, reduce the loss of cooling medium, reduce the workload of matting.
The content of the invention：
Goal of the invention of the invention is the shortcoming for overcoming prior art to exist, and proposes a kind of quenching cooler of design,
To solve the uncontrolled problem of cooling procedure, it is to avoid the phenomenon generation that workpiece produces collision, loses and obscure, cooling is overcome to be situated between
Matter produces the defect of loss with workpiece movement, solves the problems, such as that inhomogeneous cooling is even, effectively improves operating efficiency.
