Abstract
The utility model discloses a kind of open die forging hammer anvil preheating device, comprise two loop draught pipes be arranged in parallel, affixed by support between loop draught pipe; The inner side of loop draught pipe is provided with some air nozzles, and loop draught pipe is connected with inlet channel, and inlet channel is connected with sparking syringe needle, thermocouple, continuous impulse igniter and magnetic valve in turn by wire.The utility model can carry out preheating equably to upper and lower hammer anvil, effective prevention metal material part in forging process because forging surface temperature declines too fast, that metal flow rates is slack-off, the increase of forging internal-external temperature difference causes forging crack phenomenon, and, when flame is because cutting off combustion gas when the factors such as wind are extinguished, avoid gas leakage to cause potential safety hazard, substantially increase the security of this device.
Description
Technical field
The utility model belongs to materials processing technology field, is specifically related to a kind of open die forging hammer anvil preheating device.
Background technology
Metal material open die forging utilizes impulsive force or pressure, makes metal all directions Free Transform between upper and lower hammer anvil face, unrestricted and obtain the processing mode of the forging of required form and size and certain mechanical performance.
Before metal material flat-die forging, higher owing to treating forging metal temperature, when in time forging metal regional area and contact with hammer anvil after coming out of the stove, contact area must be made to produce temperature drop rapidly.If contact area temperature is lower than recrystallization temperature, in flat-die forging process, this part metals internal-external temperature difference is comparatively large, and plastic deformation is limited, easily cracks, and causes forging quality do not conform to and scrap.Therefore, for complex-shaped, the titanium metal material open die forgings that deflection is large, generally when carrying out forge hot, must carry out preheating to the upper and lower hammer anvil of equipment.
Adopt the preheating of heat material traditionally to the preheating method of hammer anvil, namely choose a metal material blank, in resistance furnace, be heated to preset temperature, insulation a period of time treats that blank is heated evenly, and then takes out, is put in the mode of carrying out preheating hammer anvil between upper and lower hammer anvil.But there is problems and deficiency in which: 1, preheated metallic blank can not mate hammer anvil completely and causes being heated uneven, 2, preheated metallic blank heating hammer anvil time can produce temperature drop fast hammer anvil preheat temperature can be caused limited; 3, heating of metal blank preheating required time is long in advance to use resistance furnace, and energy consumption is high.
Utility model content
The purpose of this utility model is to provide a kind of open die forging hammer anvil preheating device, solves the hammer anvil that existing heat material preheating method exists and to be heated uneven problem.
The technical scheme that the utility model adopts is, a kind of open die forging hammer anvil preheating device, comprises two loop draught pipes be arranged in parallel, affixed by support between loop draught pipe; The inner side of loop draught pipe is provided with some air nozzles, and loop draught pipe is connected with inlet channel, and inlet channel is connected with sparking syringe needle, thermocouple, continuous impulse igniter and magnetic valve in turn by wire.
Feature of the present utility model is also,
Sparking syringe needle and thermocouple are positioned at 1-2cm place above air nozzle.
Inlet channel is provided with air inlet main valve.
Air nozzle is equidistant spread configuration.
The beneficial effects of the utility model are, a kind of open die forging hammer anvil preheating device, the loop draught pipe be arranged in parallel by two, preheating equably can be carried out to upper and lower hammer anvil, effective prevention metal material part in forging process because forging surface temperature declines too fast, the forging crack phenomenon of generation; By arranging electroheat pair and magnetic valve, according to the opening and closing of flame temperature autocontrol valve, when flame is because cutting off combustion gas when the factors such as wind are extinguished, gas leakage is avoided to cause potential safety hazard, substantially increases the security of this device.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, a kind of open die forging hammer anvil preheating device, comprises two loop draught pipes be arranged in parallel 1, affixed by support 10 between loop draught pipe 1; Further, the inner side of loop draught pipe 1 is provided with some air nozzles 9, and air nozzle 9 is equidistant spread configuration; Loop draught pipe 1 is also connected with inlet channel 7, inlet channel 7 is provided with air inlet main valve 8, in order to control the opening and closing of whole pipeline; Inlet channel 7 is connected with sparking syringe needle 2, thermocouple 3, continuous impulse igniter 4 and magnetic valve 6 in turn by wire 5, sparking syringe needle 2 and thermocouple 3 are positioned at 1-2cm place above air nozzle 9, strike sparks probability of success highest point for Best Point with syringe needle 2 of striking sparks, and thermocouple 3 is for perception flame temperature.
Using method of the present utility model is, as shown in Figure 2,3, by the loop draught pipe 1 of this device around being positioned over upper hammer anvil 11 and lower hammer anvil 12 sidewall surfaces, open air inlet main valve 8, pass into natural gas, continuous impulse igniter 4 is utilized to light a fire to the air nozzle 9 of two loop draught pipes 1 respectively, when taking fire, thermocouple 3 is heated just can produce electromotive force, is entered the coil of magnetic valve 6 by wire 5, produce magnetic field, make magnetic valve 6 adhesive, keep magnetic valve 6 to be in opening, if fray-out of flame, then the electromotive force of thermocouple 3 disappears, and magnetic valve 6 cuts out automatically.
