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.
