Description
Technical field
The present invention relates to a kind of electric heater unit.
Background technology
During die forging was produced, metal stock all needed heating at forging money, its objective is in order to utilize the microcosmic development law in the METAL HEATING PROCESS process; Improve the plasticity of metal, reduce resistance of deformation, the blank easy deformation is flowed; Can realize smoothly being shaped; Obtain simultaneously to make up and performance after the good forging, heating is an important step in the whole forging process before the forging, and productivity ratio, assurance forging quality and the energy savings consumption etc. that improve forging are all had direct influence.But the heater on the market mainly adopts flame heat, but the working condition of flame heat is poor, and firing rate is slow, heating quality be difficult to control and the thermal efficiency low
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of simple in structure in order to solve the deficiency of prior art, and working stability is reliable, and the thermal efficiency is high, and can realize the electric heater unit of heating automation and mechanization.
Technical scheme: in order to realize above purpose; A kind of electric heater unit of the present invention, it comprises: transformer, casing, silicon carbide rod and heating clamber; Be provided with heating clamber in the described casing; Silicon carbide rod is located on the heating clamber, and the output of described transformer links to each other with the input of silicon carbide rod, and the output of silicon carbide rod links to each other with the input of transformer.
Be provided with blank in the described casing.
Described silicon carbide rod is at least two.
Beneficial effect: a kind of electric heater unit that the present invention provides; Through electric current being fed on the silicon carbide rod that is provided with in the casing; Make silicon carbide rod produce heat, heat blank with the mode of radiation and convection heat transfer' heat-transfer by convection, working stability is reliable; The thermal efficiency is high, and is big and can realize heating automation and mechanization to the accommodation of blank.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention.
As shown in Figure 1, a kind of electric heater unit of the present invention, it comprises: transformer 1, casing 2, silicon carbide rod 3 and heating clamber 4.
Be provided with heating clamber 4 in the described casing 2; Silicon carbide rod 3 is located on the heating clamber 4; The output of described transformer 1 links to each other with the input of silicon carbide rod 3; The output of silicon carbide rod 3 links to each other with the input of transformer 1, is provided with blank 5 in the described casing 2, and described silicon carbide rod 3 is at least two.
When use is of the present invention, electric current is fed on one group of silicon carbide rod 3 in the casing 2, the silicon carbide rod 3 that is provided with in the heating clamber 4 produces heats; Silicon carbide rod 3 is given blank 5 thermal energy transfer by high-temperature gas, simultaneously, changes heat energy into radiant energy through high-temperature gas and burner hearth; Radiant energy passes to metal blank 5 with the electromagnetic wave mode, and after blank 5 absorbed, radiant energy changed heat energy again into; Thereby make the blank heating, in the time need controlling to the temperature in the heating clamber 4, adjustment transformer 1; Make the alternating voltage in the circuit obtain changing, thus the heating quality of control blank 5.
The foregoing description only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
