Description
Technical field
The utility model is related to a kind of aluminum alloy forged mold preheating devices, belong to technical field of forging.
Background technology
Usually forging mold can all be preheated before forging, the pre-heating mean of forging mold has red iron to dry
Roasting, coal gas spray is baked and resistance wire preheating.Aluminium alloy forging die preheating temperature is toasted and coal gas generally at 250-350 DEG C using red iron
Spray is roasting to be easy to cause aluminium alloy forging die impression temper softening, reduces hammer die lif, and be easy to cause upper and lower forging die there are larger temperature
Difference, forging are susceptible to warpage defect.Therefore red iron baking and the roasting preheating of coal gas spray is rarely employed in aluminium alloy forging die, usually used
Resistance wire is preheated, its main feature is that needing to drill on aluminium alloy forging die, resistance wire is placed in the hole of forging die, this preheating
Mode is disadvantageous in that preheating speed is slower, while drilling reduces forging die intensity.
By new patent searching, find in relation to as follows using the prior art of resistance wire preheated mold：
Patent document 1（CN201287200）In disclose a kind of mold heating device, in powder metallurgy warm-pressing former
In for mold heat, the mold heating device includes heat-conducting plate, arranges that electric heater, electric heater connect in heat-conducting plate
Line end is in outside heat-conducting plate.Mold heating device in the utility model is easy for installation, and service life is long.
Patent document 2（CN202356438U）In disclose a kind of extrusion die heating device, the heating device include plus
Hot device and temperature controller, heater are cylindrical structure, are wound in the molding of hollow cylindrical refractory brick by heating resistance wire, add
Hot device is positioned in extrusion die when heated, and it is 0~400 DEG C to control temperature range by temperature controller, heats extrusion die
The inner surface of tool.The structure of utility model device is simple, easy to operate, and temperature control is preferable, can effectively reduce cost.
Patent document 3（CN202752378U）In disclose a kind of extrusion die heating device comprising die holder, the mould
The side setting mould of seat supports, and die sleeve is provided with forward and backward mould corresponding to the other side, and the die holder is supported with mould and die sleeve
Between anti-rotation keybar is set, more electric heating tubes are installed on the die holder, coordinate the lead-out wire of electric heating tube in being opened on die holder
Equipped with wire lead slot, the lead-out wire of the electric heating tube is drawn from wire lead slot, and is installed in the top of electric heating tube on the die holder
Heat tube cover plate.Installation mold baffle ring between the die sleeve and die holder.Above-mentioned extrusion die heating device not only heating effect it is good,
Homogeneous heating, and the leading-out wire structure of electric heating tube is safe and reliable.
Patent document 1, patent document 2 and patent document 3 all disclose a kind of mold heating device, have in common that all
Using electrical heating elements preheated mold.Patent document 1 is to heat heat-conducting plate using electric heater, and heat-conducting plate connect with cavity plate, leads
Hot plate imparts heat to cavity plate again, cavity plate heating is realized, the disadvantage is that heat transfer efficiency is relatively low.Patent document 2 includes heater and temperature
Controller is spent, the use of refractory brick is that wound resistance wire is placed in mold, by resistive heater, in a manner of heat radiation
Mold is directly heated, the disadvantage is that being not suitable for complicated aluminium alloy forging die.Patent document 3 be use electric heater for heating die holder, then
Forward and backward mould is given the heat transfer of die holder by way of heat transfer, deficiency is that heat transfer efficiency is relatively low.
Invention content
The purpose of this utility model is to provide a kind of aluminum alloy forged mold preheating device, advantage is that by aluminium conjunction
Bodkin is made upper die and lower die while being preheated, and preheating speed is fast, and upper and lower mould preheating temperature is uniform.After the utility model, do not have to
Resistance wire mounting hole is processed on aluminium alloy forging die, compared with the forging die of strip resistance silk mounting hole, without resistance wire mounting hole
Aluminium alloy forging die intensity higher.
What the technical solution of the utility model was realized in：A kind of aluminum alloy forged mold preheating device, by heat transfer plate,
Resistance heating stick, conducting wire and electronic control unit composition, it is characterised in that：Heat transfer plate is placed in the upper surface of forging lower die, heat transfer plate
Type face is with forging upper mold and forges the positive of lower die, there is hole on heat transfer plate, installation resistance heating stick on hole, resistance heating stick
It is connected by conducting wire with electronic control unit.
The good effect of the utility model is that heat transfer plate is in direct contact with forging die impression, it can be achieved that complicated is aluminum alloy forged
Upper die and lower die preheat simultaneously, and preheating speed is fast, and forging upper mold and the temperature for forging lower die are uniform.
Description of the drawings
Fig. 1 is the aluminum alloy forged mold preheating device structural schematic diagram of the utility model.
Fig. 2 is the A-A sectional views of the utility model.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings：As shown in Figs. 1-2, a kind of aluminum alloy forged mold
Preheating device is made of heat transfer plate 1, resistance heating stick 2, conducting wire 3 and electronic control unit 4, it is characterised in that：Heat transfer plate 1 is placed in
