Embodiment
as depicted in figs. 1 and 2, the adjustable steel strip water-cooled pressure plate quenching device of a kind of cooling terminal temperature, comprise upper mounted plate 14, bottom plate 12, the column 10 that connects upper mounted plate 14 and bottom plate 12, fixed plate 14 is provided with upper water box 2, described upper water box 2 bottoms are provided with top board 4, described bottom plate 12 is provided with lower header 3, described lower header 3 tops are provided with press table 5, be equipped with the steel band 1 that carries out Cooling Quenching by the heat conduction of top board 4 and press table 5 between described top board 4 and press table 5, described upper water box 2 is provided with water-in 6, at least two upper water-out mouths 8 that are set up in parallel on horizontal direction, at least two lower outlets 9 that are set up in parallel on lower water-in 7, horizontal direction are arranged on described lower header 3, be equipped with valve 18 on described upper water-out mouth 8 and lower outlet 9.Horizontal throw between described upper water-in 6 and adjacent upper water-out mouth 8 is 10cm, and the horizontal throw between described adjacent two upper water-out mouths 8 is 5cm; Horizontal throw between described lower water-in 7 and adjacent lower outlet 9 is 10cm, and the horizontal throw between described adjacent two lower outlets 9 is 5cm.Be equipped with under meter 19 on described upper water-in 6 and lower water-in 7.Be equipped with guide water board 17 in described upper water box 2 and lower header 3.Described upper water-out mouth 8 adopts 5, flows to alternate front side and the rear side that is arranged on upper water box 2 according to the water guide of guide water board 17; Described lower outlet 9 adopts 5, flows to alternate front side and the rear side that is arranged on lower header 3 according to the water guide of guide water board 17.The surface of described top board 4 and press table 5 all is electroplate with hard chrome coating 20.Fixed plate 12 is provided with and is connected to the compressed air cylinder 16 that upper water box 2 tops control upper water boxs 2 move up and down.Described upper water box 2 tops also are provided with gusset plate 13, and described compressed air cylinder 16 is connected on gusset plate 13, and the both sides of described gusset plate 13 are provided with the active slide block 11 that slips on column 10.Fixing by nut 15 between described column 10 and upper mounted plate 14, bottom plate 12.The material of described top board 4 and press table 5 all adopts the modified martensitic 65Mn steel plate that becomes.The thickness of described top board 4 and press table 5 is 4～5mm.
Adopt pressing plate heat conduction to carry out cooling to steel band in water-cooled pressure plate quenching device, the factor that affects the cooling terminal temperature of steel band has four: the one, and the length of pressing plate, the 2nd, the material of pressing plate and thickness, the 3rd, pass into the water temperature of water tank, the 4th, pass into the discharge of water tank.Material and the inflow temperature of general pressing plate are uncontrollable, therefore the length of available adjustment pressing plate and adjusting flooding velocity are controlled the cooling terminal temperature of steel band, the length of regulating pressing plate can realize by the pressing plate of replacing different lengths.
As shown in Figure 2, upper water box 2 in the present invention is provided with 1 upper water-in 6 and 5 upper water-out mouths 8, be provided with guide water board 17 in upper water box 2,5 upper water-out mouths 8 flow to alternate front side and the rear side that is arranged on upper water box 2 according to the water guide of guide water board 17, valve 18 on 5 upper water-out mouths 8 only has 1 to be opened at one time, and all the other are all closed.With reference to Fig. 1, on top board 4 between upper water-in 6 and upper water-out mouth 8 owing to constantly there being water coolant to flow through, cooling power is the strongest, it can be reduced to 500 degree following (namely walking around nose point temperature) to the temperature of steel band rapidly, come coolingly due to the water that does not have to flow on the later top board 4 of upper water-out mouth 8, its cooling power is just very weak, therefore opens the valve 18 on different upper water-out mouths 8, just be equivalent to change the length of top board 4, can regulate the cooling terminal temperature of steel band.This structure is better than regulate terminal temperature with direct adjusting pressing plate length, because this structure is as long as can realize the adjusting of cooling terminal temperature once secondary pressing plate, easy to use, and its total length is constant, therefore pressing plate is stable constant, if the pressing plate with different lengths is regulated terminal temperature, so will be with a lot of secondary pressing plates, use very inconvenient, and in the situation that pressing plate length is very short, the poor stability of pressing plate can make the steel band quenching temperature inhomogeneous.As shown in Figure 1, be equipped with under meter 19 on described upper water-in 6 and lower water-in 7, be equipped with valve 18 on described upper water-out mouth 8 and lower outlet 9, the size of regulated valve 18 can be controlled the aquifer yield of upper water-out mouth 8 and lower outlet 9, and pass through the flooding velocity that under meter 19 is observed upper water-ins 6 and lower water-in 7, can further quantitatively accurately regulate cooling terminal temperature.
The present invention can regulate the cooling terminal temperature of steel band; and simple in structure; easy to operate; must quenchant; must protecting sheet yet, the quenching cost is low, does not pollute the environment; can be used to carry out the steel band martempering, also can be used to carry out steel band bainitic hardening and steel band shellfish horse complex phase and quench.
