Abstract
The utility model relates to a liquid cooling forging and stamping die which comprises a forging die subassembly and a cooling device, wherein the forging die subassembly comprises an upper die, a lower die and heating plates which are respectively arranged on the working surfaces of the upper die and the lower die; and the cooling device is fixedly arranged on the upper die, a connector which can be fixedly connected with a press punching handle is arranged on the top surface of the cooling device, the cooling device can be isolated between the press punching handle and the upper die and fixedly connects the press punching handle and the upper die, so that heat which is transferred to the press punching handle can be reduced, the punching handle is kept at low temperature, the fit precision and dynamic performance are prevented from being reduced due to the overtemperature punching handle, the working performance of a press is not influenced, and the working quality and working efficiency of the press can be ensured.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of liquid cooling forge die.
Background technology
Forging die is a kind of for a kind of mould of industrial product by pressure forming; by being exerted pressure, the thermal state metal blank make metal generation plastic deformation or fracture be processed into part; generally by patrix; counterdie and the heating plate that is arranged on the upper and lower mould working face consist of; forging die usually is installed on press and uses; counterdie is fixed in the press lower table; patrix is fixed in the press die shank; make workpiece machine-shaping between the upper and lower mould heating plate under the drive of die shank; add the man-hour heating plate and have higher temperature; be used for reducing and the thermal state metal blank between the temperature difference; be beneficial to the plastic deformation of workpiece; but heating plate is positioned at the working face surface; need to fit tightly with upper and lower mould; therefore can pass to corresponding patrix or counterdie by the most of heat of heat exchange action; its patrix of forging die of the prior art directly is connected with the press die shank; make heat further pass to die shank; cause pressing the part quality of fit that is slidingly matched of die shank to descend; hydraulic cylinder such as hydraulic press; piston rod and cylinder barrel sealing property are descended; hydraulic fluid temperature raises; even the damage seal, cause leakage of oil, the press service behaviour is descended.
Therefore, for addressing the above problem, need the forging die structure is improved, reduce the heat that passes to the press die shank, do not affect the press service behaviour.
The utility model content
In view of this, the purpose of this utility model provides a kind of liquid cooling forge die, is provided with liquid cooling system, can reduce the heat that passes to the press die shank, does not affect the press service behaviour.
Liquid cooling forge die of the present utility model comprises forging die assembly and cooling device, and the forging die assembly comprises upper die and lower die and is arranged at respectively heating plate on the working face of upper die and lower die; Described cooling device is fixedly installed on patrix, and the cooling device end face is provided with the connector that can be fixedly connected with the press die shank.
Further, described cooling device adopts liquid cools;
Further, described cooling device comprises the cooling body with cooling sap cavity and is arranged at the interior fin of cooling sap cavity, be provided with on the cooling body and the inlet and the liquid outlet that cool off sap cavity and communicate, fin is for vertically being fixed in a plurality of that cooling sap cavity diapire equidistantly arranges, and described connector is positioned at the cooling body end face and is wholely set with it;
Further, described inlet and liquid outlet with its center line perpendicular to fin and low in and high out setting;
Further, described connector press die shank is threaded connection, and is provided with on the connector for the press die shank being connected the bung flange that compresses.
Liquid cooling forge die of the present utility model, be provided with liquid cooling apparatus, liquid cooling apparatus can be isolated between press die shank and the patrix and with them and be fixedly connected with, can reduce the heat that passes to the press die shank, keep die shank to be in lower temperature, prevent that die shank from because quality of fit and the power performance that excess Temperature causes descends, not affecting the press service behaviour, can guarantee crudy and the operating efficiency of press.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Fig. 1 is structural representation of the present utility model, as shown in the figure: the liquid cooling forge die of present embodiment, comprise forging die assembly and cooling device 1, the forging die assembly comprise patrix 2, counterdie 3 and be arranged at respectively patrix 2 and the working face of counterdie 3 on heating plate 4; Described cooling device 1 is fixedly installed on patrix 2, cooling device 1 end face is provided with the connector 11 that can be fixedly connected with the press die shank, liquid cooling apparatus 1 can be isolated between press die shank and the patrix 2 and with them and be fixedly connected with, can reduce the heat that passes to the press die shank, keep die shank to be in lower temperature.
In the present embodiment, described cooling device 1 adopts liquid cools, and cooling performance is good.
In the present embodiment, described cooling device 1 comprises the cooling body 13 with cooling sap cavity 12 and is arranged at the fin 14 that cools off in the sap cavity 12, be provided with on the cooling body 13 and the inlet 15 and the liquid outlet 16 that cool off sap cavity 12 and communicate, fin 14 is for vertically being fixed in a plurality of that cooling sap cavity 12 diapires equidistantly arrange, described connector 11 is positioned at cooling body 13 end faces and is wholely set with it, reasonable in design, cooling fluid can contact with larger area with fin 14, and heat exchange effect is good.
In the present embodiment, described inlet 15 and liquid outlet 16 with its center line perpendicular to fin 14 and low in and high out setting, be subject to the barrier effect of fin 14 when making cooling fluid enter liquid cooling apparatus 1, form stronger eddy current, make cooling fluid and cooling body 13 heat exchanges more abundant.
In the present embodiment, described connector 11 is threaded connection with the press die shank, is provided with on the connector 11 for the press die shank is connected the bung flange 17 that compresses, and structure is more firm, easy accessibility.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
