Background technology
When the most large-scale plate of metalwork carries out heat treatment, first metalwork being needed after rolling is cooled to room temperature or direct quenching obtains required product or semi-finished product, in cooling procedure, in order to ensure that the mechanical performance of large-scale plate is wanted uniform, constant speed and lowers the temperature plate rapidly when just requiring and cool down;But existing workpiece is in heating and cooling procedure, inconsistent due to top layer and the rate of cooling in heart portion and time, form the temperature difference, may result in volumetric expansion and shrink uneven and produce thermal stress, under the effect of thermal stress, owing to top layer starts temperature less than heart portion, shrink and make heart portion tension also greater than heart portion, when cool down is complete, owing to heart portion finally cools down, volume contraction can not freely carry out and make pressurized heart portion, top layer tension, this phenomenon is cooled speed, the impact of the factor such as material composition and Technology for Heating Processing, when rate of cooling is the fastest, phosphorus content and alloying component are the highest, the uneven plastic deformation produced under thermal stress effect in cooling procedure is the biggest, the residual stress eventually formed is the biggest;On the other hand workpiece in heat treatment process due to tissue change i.e. austenite to martensite transfor mation time, because increasing of specific volume can be with the expansion of workpiece volume, the successively phase transformation of each position of workpiece, cause volume length to make great difference and produce structural stress.The final result of structural stress change is top layer tension stress, heart portion compression chord, the most contrary with thermal stress, thus quenching rate of cooling is one and can affect quenching quality and determine the key factor of residual stress, is also one and hardening flaw can be given important or even material factor.In order to reach the purpose of quenching, it is often necessary to accelerate part rate of cooling in high temperature section, just and critical hardening rate of cooling past workpiece can obtain martensitic structure.And existing chiller, rate of cooling is inadequate, thus causes workpiece deformation relatively big, even scraps.
Utility model content
Problem to be solved in the utility model is to provide that a kind of rate of cooling is fast, pressure quenches dynamics adjustable pressure quenching radiator cooler.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: have lower carriage, and this lower carriage is connected with upper pressure support and upper bracket by lead, and described upper pressure support is travel(l)ing rest and is located between described lower carriage and described upper bracket;Described upper bracket top is provided with the power assembly making pressure support move up and down, and the drive link of this power assembly is connected with described upper pressure support;Described upper pressure frame bottom is provided with top nozzle pressure head, and described lower carriage top is provided with lower nozzle pressure head;It is provided with lifting transmission bracket between described upper pressure support and described lower carriage, in this lifting transmission bracket, is provided with conveying roller.
In technique scheme, more specifically scheme is it may also is that described lifting transmission bracket is respectively arranged at two ends with a column, this column bottom is fixed on described underframe, and this column top is interspersed with described lifting transmission bracket end face, is socketed with compression spring outside described column.
Further: described upper and lower nozzle pressure head is for having a square water pipe, and this square water pipe is externally provided with press strip in the face of that side tube wall of workpiece, and this side pipe wall is provided with multiple water spray inclined hole;It is provided with multiple tank along this press strip length direction on described press strip face.
Further: described square water pipe is provided with connection bent plate, is fixed with push pipe under the flanging of this connection bent plate, the other end of this push pipe is located on described square water pipe;Connect in the middle part of described square water pipe and have water inlet pipe.
Further: described power assembly is hydraulic cylinder assembly.
Owing to using technique scheme, this utility model compared with prior art, has the advantages that
1, owing to being provided with travel(l)ing rest between upper bracket and lower carriage, travel(l)ing rest is driven by machine power and makes it move up and down, and speed and strength is the most adjustable;Upper pressure frame bottom is provided with top nozzle pressure head, lower carriage top is provided with lower nozzle pressure head, it is provided with lifting transmission bracket between upper pressure support and lower carriage, it is provided with conveying roller in this lifting transmission bracket, can quickly the workpiece after heating be delivered between upper and lower nozzle pressure head, after pressure head is pressed onto workpiece, nozzle sprays water at once and quickly cools down workpiece, thus avoids the most yielding problem of workpiece.
2, it is respectively arranged at two ends with a column due to lifting transmission bracket, this column bottom is fixed on underframe, this column top is interspersed with lifting transmission bracket end face, compression spring it is socketed with outside column, when upper pressure support is pressed downward against workpiece, lifting transmission bracket the most and then sinks, and now compression spring plays cushioning effect;After pressure quenches end, spring pops up reset, lifting transmission bracket is upwards pushed up, is ejected by workpiece, makes workpiece be higher than lower nozzle pressure head, facilitates conveying roller to be sent.
3, owing to having multiple water spray inclined hole on the sidewall of square water pipe, making the water gushed out is fan-shaped spray, sprays water wide, is evenly distributed, and can spray water on workpiece uniformly, make workpiece quickly cool down.
