Description
Technical field
The invention belongs to electric radiation technical field of heating, relate to a kind of forging die heater, particularly relate to a kind of for electricity
The detachable electric radiation formula forging die heater of dynamic fly press and method for determining size.
Background technology
Numerical-control electric screw press system has been used for a kind of forging equipment of the technique such as die forging, finish forge.Wherein, hot-forging die
Tool, Warm Forging Die and cold forging die are all to work under high dynamic loading or dead load repeated action, and operationally should
Power changes the most greatly, i.e. drastically raises and the stress relieved when unloading at loading instantaneous stress, work under bad environment.
Under equipment and forging die condition stable condition, using and safeguarding the most proper of forging die, forging die will be directly affected
Service life and the output quality of forging, production cost, production efficiency.Under normal circumstances, before work, according to technological requirement need by
Forging die on numerical-control electric screw press is preheating to 150 DEG C～the temperature of 300 DEG C, in this temperature range, and mould tough
Property is in optimum state；Another because forging die system is made up of high-alloy steel, there is certain fragility, the steel phase of cold mold and high temperature
Contact can make forging die surface produce size thermal expansion in moment, and its heart portion temperature is low does not expands, on the one hand institute's forged steel material can not
Fill mould type groove well and existing releasing agent is not applied for cold mold application, it addition, also easily cause the meeting of forging die surface
It is opened, forms be full of cracks.So, for this occurred the problems referred to above that contact with cold-forging die because of high-temperature forging, existing public affairs
Know that technology carries out Forging Operation after usually needing to preheat forging die again.
At present, the known method adding hot-forging die employing has following several:
1, mould bases perforate pre-heating mean.Mean perforate on forging die frame, and heat pipe will be added stretch in hole, make to add thermotube wall and be close to
Mould bases hole wall, when adding heat pipe electrified regulation, conducts heat on mould bases by its tube wall, is transmitted on forging die the most again.
This method, for baby press, there is no problem, but for the bigger forging die of size and weight, passes through mould bases
Conduction heat, power attenuation is relatively big, and conduction efficiency is extremely low, i.e. applicable surface is narrow.Such as the electric screw press mould bases weight used
About 2500kg, forging die weight about 260kg, all heat the mould bases of 2500kg be transmitted to heat the forging die of 260kg
On forging die, it is clear that be inappropriate.
2, gas heating method is used.Mean use combustion heater, forging die is heated slowly to required temperature range.
This method, needs to use naked light and inflammable gas, to workshop condition and all can cause disadvantageous shadow with fire safety
Ring, the most dangerous, and waste time and energy.
3, Toona sureni material heating means are burnt.Mean burning red bar, be heated approximately to 1100 DEG C, be placed on anvil tool,
Upper forging die is displaced downwardly to the position close to bar, is conducted by heat and radiate, upper anvil tool is heated.
This method easily makes die surface anneal, and reduces die hardness, goes up anvil tool simultaneously and be heated uneven, i.e. lower forging
Mould is owing to directly contacting bar, and the temperature of conduction is higher, and upper forging die is near bar, and heating is by heat radiation, and temperature is relatively low, i.e. adds
Heat is uneven.On the other hand, after having heated with bar, in addition it is also necessary to the bar after manually using is cleaned to bar case, at this moment rod
The temperature of material is the highest, and misoperation can cause scald accident.
In summary, contact with high temperature steel and make forging die surface generation size expansion and can for solving cold-forging die
Fill mould type groove and the use of existing releasing agent well, it addition, for avoiding causing forging die surface to be opened, form be full of cracks
Etc. problem, add the method that hot-forging die used there are some beneficial effects though above-mentioned, make the most in actual use
Cross some positive contributions, but, still there is also that heating means applicable surface is narrow, use dangerous and heat the aspects such as uneven
Problem.It can be said that existing known technology still has some limitation and technical deficiency, this is also that needs solve
Practical problem.
Summary of the invention
For solving above-mentioned deficiency, the invention discloses a kind of detachable electric radiation formula forging die heater and the size side of determination

Enable its forging die each several part to reach required technological temperature simultaneously, be possible not only to solve to add the method applicable surface of hot-forging die in the past
Narrow, use problem that is dangerous and that heat the aspect such as uneven, and the efficiency of heating surface can be improved, meet its technological requirement,
And the generation of the situations such as its be full of cracks can be prevented, and there is propagable practical value.

5) determination of device spacing degree of depth h4 size
h4 = h7
In above-mentioned formula, h4 is the spacing degree of depth of device, and h7 is limited a disc height；
So far, the size determined needed for forging die heater of the present invention, all determine to this.
Below, for an embodiment, the size determined needed for a kind of forging die heater of the present invention is illustrated really
Determine method, as follows:
Known by Fig. 5, Fig. 6: certain enterprise's numerical-control electric screw press 15 forging die, its heating requirements is: diameter phi 420mm, highly
135mm, the upper forging die 11 of weight about 130kg and the anvil tool 12 of same size and weight, in 50 minutes, heating reaches technique
The temperature 150 DEG C required.
In this embodiment, the anvil tool 12 of forging die 11 and same size and weight in heating, it is thus necessary to determine that institute of the present invention
State the device internal diameter φ 1 involved by forging die heater, device external diameter φ 2, device height h, device spacing internal diameter φ 3, device
Spacing degree of depth h4 totally five relative dimensions, in order to next step design of device and making.Step is as follows:
1) determination of device internal diameter φ 1
φ1=φ4 + 2δ3
∵ φ4=420mm δ3=15mm
Illustrating: mold external diameter φ 4 value is 420mm, forging die with distance δ 3 value of unidirectional loop irradiator inner surface is
15mm；
∴ φ1=φ4 + 2δ3 = 420+2×15=450mm
2) determination of device external diameter φ 2
φ2=φ1+2w1+2w2
∵ φ1=450mm w1=10mm w2=40mm
Illustrate: unidirectional loop irradiator thickness w1 value is 10mm, and thickness of shell w2 value is 40mm；
∴ φ 2=φ 1+2w1+2w2=φ 1+(w1+w2) × 2=450+(10+40) × 2=550mm；
