Description
Technical field:
The present invention relates to a kind of firing equipment, specifically is that a kind of electromagnetic induction principle that utilizes comes the diathermic furnace that metal stock is heated.
Background technology:
Products such as some auto parts and components, securing member, gear, semiaxis connecting rod all are stamped to form by metal stock usually; When these products of punching press; At first need metal stock be put into diathermic furnace heats; After treating that metal stock reaches required press temperature, utilize stamping machine that metal stock is carried out punching press again, obtain corresponding product at last.We know that a plurality of metal stocks some substandard products can occur when in diathermic furnace, heating simultaneously unavoidably, as burning or the low excessively metal stock of temperature occur; So-called burning is exactly the overlong time that metal stock stops in the burner hearth of diathermic furnace, causes its surface oxide layer to thicken, and causes the obdurability at punching press position to worsen; Thereby in the service life of finished product after the shortening punching press, it then is because the time that metal stock stops in burner hearth is too short that temperature is crossed low, causes self temperature low excessively; Can't on stamping machine, carry out punching press smoothly, the service life of stamping machine is shortened in the punching press meeting by force, and hence one can see that; The metal stock that burning or temperature are low excessively can not flow into next stamping procedure again and carry out punching press; No matter temperature has or not metal stock after diathermic furnace heating reaches the punching press requirement, gets into next stamping procedure without exception but in the prior art; And strike out product by stamping machine, cause the scrappage of product higher.
Summary of the invention:
The technical problem that the present invention will solve is, provide a kind of at the metal stock after the heating when the burner hearth discharging opening flows out, can burning or the low excessively metal stock of temperature be filtered out, thereby reduce the diathermic furnace of stamping products scrappage greatly.
Technical solution of the present invention is; A kind of diathermic furnace with following structure is provided: the body of heater that comprises cabinet rake and be connected the cabinet rake top; Be provided with in the body of heater and be used for burner hearth that metal stock is heated, the burner hearth left end is a charging aperture, and the burner hearth right-hand member is a discharging opening; The discharging opening place is provided with quickly discharging mechanism; Be provided with the guide rail that is used for the support metal blank in the burner hearth, wherein, the discharging opening place also is provided with and is used for self-emptying sorting device that burning or the low excessively metal stock of temperature are detected.
Diathermic furnace of the present invention; Wherein, The track plate that the self-emptying sorting device can comprise infrared thermometry probe, infrared temperature controller, support and be connected a top of the trellis; The track plate is positioned at quickly discharging mechanism right-hand member; The track plate is provided with burning and scraps passage, temperature and cross low passage and scrap passage in burning and cross the qualified passage that hangs down between the passage with temperature; Burning is scrapped between passage and the qualified passage and is provided with first turnover door, and temperature is crossed between low passage and the qualified passage and is provided with second turnover door, and track plate bottom is connected with first control valve and second control valve that is used to control the second cylinder source of the gas break-make that is respectively applied for first cylinder and second cylinder that drives first turnover door and the rotation of second turnover door and is used to control the first cylinder source of the gas break-make; All be welded with trundle on first turnover door and second turnover door; All be hinged with spill spin block on the piston rod of first cylinder and second cylinder, trundle one end passes the track plate and is fixedly connected with spill spin block, and the infrared thermometry probe is positioned at quickly discharging mechanism top and is connected with cabinet rake; The infrared temperature controller is contained on the cabinet rake, and infrared thermometry probe, first control valve and second control valve all are electrically connected with the infrared temperature controller.
After adopting above structure; Compared with prior art; Diathermic furnace of the present invention has the following advantages: the self-emptying sorting device that the discharging opening place is provided with can detect and screen the metal stock after the heating; Have only the satisfactory metal stock of temperature value just can get into next stamping procedure, and for burning or the low excessively metal stock of temperature, this self-emptying sorting device can take out it.
When the metal stock after the heating flowed out from the discharging opening of burner hearth, the infrared thermometry probe that is positioned at quickly discharging mechanism top was started working, and learns the temperature of metal stock through infrared thermometry; And this temperature signal is transferred to the infrared temperature controller, finally judge by the infrared temperature controller whether this metal stock is qualified, if this temperature conforms to the temperature value that the infrared temperature controller pre-sets; Explain that then this metal stock is qualified, first cylinder and second cylinder all are failure to actuate, and qualified metal stock gets into next stamping procedure from qualified passage; If measured temperature is too high, i.e. metal stock burning, the infrared temperature controller can be controlled first control valve and make the action of first cylinder; First turnover door is opened; The metal stock of burning is scrapped passage from burning and is flowed out, if the temperature that records is low excessively, the infrared temperature controller can be controlled second control valve and make the action of second cylinder; Second turnover door is opened, and the metal stock that temperature is low is excessively crossed low passage from temperature and flowed out.We are not difficult to find out through foregoing; Diathermic furnace of the present invention is after having heated metal stock; The metal stock that only temperature is reached the punching press requirement is sent into next stamping procedure, and burning or the low excessively metal stock of temperature are filtered out, thereby greatly reduces the scrappage of postorder stamping products.
