Description

A kind of novel refrigeration muffle

Technical field

The utility model belongs to the refrigeration muffle technical field of industrial heating furnace, particularly the novel refrigeration muffle of one.

Background technology

Net belt type protective atmosphere continuous brazing furnace is widely used in other heat treatment of the soldering, annealing etc. of the part such as stainless steel, carbon steel, brass, red copper of the industries such as electronics, automobile, air conditioner refrigerating, Aero-Space, is also applied to the sintering of powder metallurgy, reduction etc.

Refrigeration muffle is made up of multistage, is the important component of horse not meshbeltfurnace.Workpiece carries out Slow cooling by refrigeration muffle after high temperature horse not heat treatment.Easily there is the phenomenons such as burn into crackle in refrigeration muffle at high temperature weld seam.The phenomenons such as burn into crackle not appear in conventional chilling horse during when weld seam, water can infiltrate horse not thus affect the protective atmosphere of workpiece by weld seam.Cause workpiece of coming out of the stove defective.Refrigeration muffle is generally made up of refrigeration muffle tank and the water jacket be arranged on outside it, because the weld seam of refrigeration muffle tank contacts with water jacket inner cooling water, in Long-Time Service process, water in water jacket can infiltrate from weld seam the composition that have impact on the protective atmosphere in stove refrigeration muffle tank, thus affects the quality of workpiece; The stress not producing Swelling and contraction due to horse in heating with cooling procedure at cooling section horse first paragraph not is not structurally absorbed, and makes repeatedly to expand, horse after contraction distortion not produces cracking damage, thus lowers horse service life not.

Utility model content

The purpose of this utility model is to provide a kind of novel refrigeration muffle, and this refrigeration muffle can be good at avoiding cooling water to infiltrate into the inside of Muffle pot by weld seam, and can absorb the stress of Swelling and contraction, thus extends horse service life not.

For reaching above object, the utility model is achieved by the following technical solutions.

A kind of novel refrigeration muffle, it is characterized in that: comprise the Nei Mafu be welded by first Nei Mafu and second Nei Mafu, first Nei Mafu above the weld of first Nei Mafu described and second Nei Mafu is outside equipped with upper water sleeve, second Nei Mafu below the weld of first Nei Mafu described and second Nei Mafu is outside equipped with lower water jacket, is communicated with circulating water pipe between described upper water sleeve and lower water jacket; The bottom surface of second Nei Mafu described is provided with at least one bending groove to lower recess, described bending groove extends at the length direction of the bottom surface of second Nei Mafu, and runs through the whole length direction of the bottom surface of second Nei Mafu described.

The feature of technique scheme and improvement further:

Further, brace rod is connected between described upper water sleeve and first Nei Mafu, between described lower water jacket and second Nei Mafu.

Further, described bending groove is " U " shape.

Further, described bending groove is " V " shape.

Refrigeration muffle of the present utility model, adopt the isolation technics of Nei Mafu and water jacket welded seam, namely the weld weld seam of Nei Mafu does not contact with water jacket, such cooling water just can not leak in refrigeration muffle, also just ensure that the protective atmosphere of refrigeration muffle is not destroyed, thus guarantee heating, cooled workpiece light; Bending groove fully can absorb the stress because expanded by heating, cooling meat produce, thus extends horse service life not.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of novel refrigeration muffle of the present utility model;

In figure: 1, first Nei Mafu; 2, second Nei Mafu; 3, upper water sleeve; 4, lower water jacket; 5, brace rod; 6, circulating water pipe; 7, weld; 8, cooling water; 9, bending groove.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

With reference to Fig. 1, it is the structural representation of a kind of novel refrigeration muffle of the present utility model; This refrigeration muffle comprises the Nei Mafu be welded by first Nei Mafu 1 and second Nei Mafu 2, first Nei Mafu 1 above the weld 7 of first Nei Mafu 1 and second Nei Mafu 2 is outside equipped with upper water sleeve 3, second Nei Mafu 2 below the weld 7 of first Nei Mafu 1 and second Nei Mafu 2 is outside equipped with lower water jacket 4, upper water sleeve 3 is that the outer surface seal welding of first Nei Mafu 1 above the weld of metal material and upper and lower Nei Mafu is formed, and lower water jacket 4 is that the outer surface seal welding of second Nei Mafu 4 below the weld of metal material and upper and lower Nei Mafu is formed; Circulating water pipe 6 is communicated with between upper water sleeve 3 and lower water jacket 4; The bottom surface of second Nei Mafu 2 is provided with at least one bending groove 9 to lower recess, bending groove 9 extends at the length direction of the bottom surface of second Nei Mafu 2, and runs through the whole length direction of the bottom surface of second Nei Mafu 2.

Upper water sleeve 3 and lower water jacket 4 do not wrap up the weld seam of Nei Mafu, and cooling water 8 just can not leak into Nei Mafunei, just ensure that the composition of the protective atmosphere of cooling Nei Mafuli is not destroyed yet, thus guarantee heating, cooled workpiece light.

Brace rod 5 is connected between upper water sleeve 3 and first Nei Mafu 1, between lower water jacket 4 and second Nei Mafu 2.Brace rod 5 plays the effect supporting upper water sleeve 3 and lower water jacket 4, effectively can prevent the distortion of upper water sleeve 3 and lower water jacket 4.

Bending groove 9 is set to " U " shape, also can be set to " V " shape as required, or other shape beyond these two kinds of shapes.The quantity of bending groove 9 also can be set to two or more as required.Bending groove 9 fully can absorb the stress because expanded by heating, cooling meat produce, thus extends horse service life not.

Although be below described embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned specific embodiments and applications field, above-mentioned specific embodiments is only schematic, guiding, instead of restrictive.Those of ordinary skill in the art is under the enlightenment of description, and when not departing from the scope that the utility model claim is protected, can also make a variety of forms, these all belong to the row of the utility model protection.
