Background technology
Steel band quenches and generally all uses oil spout pressing plate equipment, and this equipment is the product of the sixties in last century, and machine oil is sprayed onto on the steel band of flag heat, can produce a large amount of smog, makes that whole workshop is filled with smoke, and the workshop is greasy dirt everywhere, serious environment pollution.The patent No. is 200810063322.5 patent of invention; A kind of steel band water cooling pressing plate quenching device is provided; This device is that water feeds water tank and cools off pressing plate, utilizes the heat conducting principle of solid to cool off steel band with pressing plate again, and steel band does not contact with water; Can not produce smog, so do not pollute the environment.Compare with the oil spout pressing plate, it is non-environmental-pollution not only, and without machine oil, has reduced steel band thermal treatment cost.But it has four shortcomings: the one, use protecting sheet, and the effect of protecting sheet is to be used for protecting pressing plate and steel band, and it can not pulled in quenching process, this has just increased the cost that steel band quenches; The 2nd, softer as the expanded graphite quality of protecting sheet; Steel band is if there is the dust in uneven or jagged or the process furnace to be taken out of the rill that all can on protecting sheet, pull out a rule; Make and leave a lot of graphite stripeds in steel strip surface; Form a lot of stripeds in steel strip surface after the tempering, influence the surface quality of steel band; The 3rd, because work-ing life of protecting sheet is not long, often change, make workman's troublesome poeration, and change protecting sheet at every turn, all can scrap the steel band more than a meter, increased the heat treated scrap rate of steel band; The 4th, owing to used the capacity of heat transmission that has reduced pressing plate behind the protecting sheet, so this equipment just can not through hardening for thicker steel band.
Summary of the invention
The utility model technical problem to be solved is to provide a kind of steel band water cooling quenching device of unprotect plate; Can reduce the heat treated cost of steel band, reduce the striped of steel strip surface, improve the surface quality of steel band; Reduce the heat treated scrap rate of steel band, improve the hardening capacity that steel band quenches.
For solving above-mentioned existing technical problem; The utility model adopts following scheme: a kind of steel band water cooling quenching device of unprotect plate; Comprise upper mounted plate, bottom plate, be fixed on the column between upper mounted plate and the bottom plate, said upper mounted plate is provided with upper water box, and said upper water box bottom is provided with top board; Said bottom plate is provided with lower header; Said lower header top is provided with press table, is equipped with the steel band that carries out Cooling Quenching through the heat conduction of top board and press table between said top board and the press table, and the surface of said top board and press table all is electroplate with hard chrome coating.
As preferably, the material of said top board and press table all adopts the modified martensitic 65Mn steel plate that becomes.
As preferably, the thickness of said top board and press table is 4～5mm.The capacity of heat transmission is good.
As preferably, said upper mounted plate is provided with the compressed air cylinder that the control upper water box moves up and down.
As preferably, said upper water box top is provided with gusset, and the both sides of said gusset are provided with the active slide block that slips on column.Guaranteed the parallel motion up and down of upper water box.
As preferably, said upper water box is provided with water-in and upper water-out mouth, and following water-in and lower outlet are arranged on the said lower header.
As preferably, be equipped with guide water board in said upper water box and the lower header.Increase heat conductivility.
As preferably, fix through nut between said column and upper mounted plate, the bottom plate.It is firm to connect.
Beneficial effect:
The utility model adopts technique scheme that a kind of steel band water cooling quenching device of unprotect plate is provided; Saved protecting sheet; Reduce the cost that steel band quenches, reduced the striped of steel strip surface, improved the surface quality of steel band; Reduce the heat treated scrap rate of steel band, improved the hardening capacity that steel band quenches.
