Abstract
The present invention provides a technical scheme of a bell type tempering furnace for heating metal parts by protective gases, which is characterized in that the present invention is provided with an inner cover made from stainless steel material; the inner cover is arranged on a base; a sand sealing groove is arranged on the periphery of the inner cover; an outer cover covers the sand sealing groove; a centrifugal fan is arranged in the center position on the base in the stainless steel inner cover; an electric heating device is arranged on the periphery of the centrifugal fan; an annular partition board is arranged on the centrifugal fan and the electric heating device; a material frame is placed on the partition board; a main shaft of the centrifugal fan is connected with a motor below the base.
Description
What the present invention relates to is a kind of heat treatment furnace, and especially a kind of metal parts that is used for is at the annealing, the tempering bell tempering furnace that charge into the shielding gas heating.
Bell tempering furnace in the prior art also has an inner cover; processed metal parts is contained in its inner cover, and fills with shielding gas, and outer cover is to be made by steel plate and refractory materials; electricradiator just is arranged on the inwall of outer cover, so outer cover plays the dual function of insulation and thermal source.This structure has the too heavy problem of outer cover self inevitably, and the weight handling equipment that in use requires to have certain weight-lifting ability just can.
Purpose of the present invention is exactly at the existing in prior technology problem, and provides a kind of metal parts that is used for by interior bell tempering furnace technical scheme of filling the shielding gas heating.
This programme is realized by following technical measures.A kind of bell tempering furnace mainly is made up of outer cover, inner cover, sand seal, base, bin and electricradiator, and the characteristics of this programme are that described inner cover is to be located on the base, is sand sealing groove around the inner cover, and outer cover promptly covers on the sand sealing groove; Centre in the cover of inner cover on the base, centrifugal fan is arranged, and is electricradiator around centrifugal fan, on centrifugal fan and electricradiator toroidal membrane is arranged, then be placed with bin on the dividing plate, the main shaft of described centrifugal fan is connected with motor under the base.
For clearly demonstrating the technical characterstic of this programme, now by a specific embodiment, and in conjunction with its accompanying drawing, the technical characterictic of this programme is described in detail.
Description of drawings:
Accompanying drawing 1 is the structural representation of the embodiment of the invention.
By accompanying drawing as can be seen, the bell tempering furnace of this programme, an outer cover 4 and an inner cover 5 made from stainless steel that has suspension ring 11 is arranged, described stainless steel inner cover 5 is to be located in one to have on the base 2 of boss, around the stainless steel inner cover 5 is sand sealing groove 3, outer cover 4 promptly covers on the sand sealing groove 3, is used for sealing the space between stainless steel inner cover 5 and the outer cover 4, so that insulation.Centre in the cover of stainless steel inner cover 5 on the base 2, centrifugal fan 8 is arranged, around centrifugal fan 8 is electricradiator 9, on centrifugal fan 8 and electricradiator 9, toroidal membrane 7 is arranged, then be placed with the bin 6 that mounts processed part on the dividing plate 7, the main shaft of described centrifugal fan 8 is connected with motor 1 under the base 2.Described centrifugal fan 8 and electricradiator 9 also can be placed on the top of bin 6, its effect be the same 6 times at bin.Junction at described stainless steel inner cover 5 and base 2 also has sealing-ring 10, the sealing when guaranteeing in inner cover 5 inflation.
The bell tempering furnace of said structure; because electricradiator is within inner cover; force the shielding gas circulation that charges into the centrifugal fan that places the electricradiator center again, make heat be taken away and be passed to heated part by shielding gas, case temperature can promote and balance faster.Outer cover is because no longer play the dual function of thermal source and insulation, and has been an insulation effect, so all can lower the requirement at aspects such as thickness, this can alleviate himself weight greatly.This internal heat type structure has not only alleviated the weight of outer cover, but also has saved electric power, has reduced energy consumption.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement.
