Description

A kind of heat-treatment furnace

Technical field

The utility model relates to the printing field 3d more particularly to a kind of heat-treatment furnaces.

Background technique

Part after 3d has been printed needs to be annealed by heat-treatment furnace to be homogenized internal crystal phase to improve stability, but Since the distance between position each in furnace and filament differ, in-furnace temperature is unevenly distributed, and influences final annealing effect.

Utility model content

The problem to be solved by the utility model is to provide a kind of heat-treatment furnaces, so that being put into the part wherein annealed Can thermally equivalent, the utility model solves the technical problem in the following way: a kind of heat-treatment furnace, including furnace body, described It is equipped with furnace chamber open at one end in furnace body, is equipped with heater strip in furnace chamber, furnace chamber inner wall is lined with refractory brick, it is characterised in that: described Support device is additionally provided in furnace chamber, the support device includes support plate and the pillar set on support plate bottom, the support Plate by pillar supporting in the middle part of furnace chamber, when use article place on the supporting plate, due in the middle part of furnace chamber it is heated more uniformly, thus Better annealing effect can be obtained.

In further improvement of the utility model, the posts bottom is equipped with bottom plate, the fire resisting of the furnace cavity bottom Brick is equipped with two guide rails being parallel to each other, and the opposite side side wall of the guide rail is equipped with groove, and the bottom edge can It is caught in the groove, can easily adjust position of the support plate in furnace chamber.

As a kind of preferred embodiment of the utility model, at the oven cavity opening end be equipped with fire door, the fire door with It is connected by a hinge between furnace body.

As a kind of preferred embodiment of the utility model, the guide rail extends towards the direction of fire door, works as needs in this way In use, being sent into support device from fire door, the bottom plate of support device is connected on guide rail and is slid into, that is, completes installation, when When needing to dismantle, support device is skidded off into fire door along track and completes disassembly, is dismounted easily.

As a kind of preferred embodiment of the utility model, the heater strip is set to below the refractory brick of furnace chamber bottom surface, The refractory brick of the furnace chamber bottom surface is equipped with through-hole.

As a kind of preferred embodiment of the utility model, the pillar is metal hollow cylinder, to lower Overall weight, it is easier to operate.

In summary, using the utility model, enable part thermally equivalent, annealing effect is more excellent.

Detailed description of the invention

The utility model is further described below in conjunction with attached drawing:

Fig. 1 is the utility model sectional view；

Fig. 2 is the top view of the utility model；

Wherein: 100- furnace body, 200- furnace chamber, 300- refractory brick, 301- through-hole, 400- heater strip, 500- support plate, 510- pillar, 520- bottom plate, 530- guide rail, 600- fire door, 601- hinge.

Specific embodiment

The utility model is further elaborated below by way of specific embodiment:

As depicted in figs. 1 and 2, a kind of heat-treatment furnace, including furnace body 100, furnace body 100 is interior to be equipped with furnace chamber open at one end 200, it is equipped with fire door 600 at the open end of furnace chamber 200, is connected between fire door 600 and furnace body 100 by hinge 601, fire door 600 closes Furnace chamber 200 can be sealed when closing.

200 inner wall of furnace chamber is lined with refractory brick 300, heater strip 400 is equipped with below the refractory brick 300 of 200 bottom surface of furnace chamber, to make Heat can be efficiently passed in furnace chamber 200, and through-hole 301 is evenly distributed on the refractory brick 300 of 200 bottom surface of furnace chamber for adding The heat of heated filament 400 passes through.

In order to enable the workpiece being sent into heat-treatment furnace obtains better annealing effect, and it further include a support device, branch Support arrangement includes support plate 500, the pillar 510 at 500 bottom surface center of support plate, and support plate 500 is supported extremely by pillar 510 The middle part of furnace chamber 200, uniform heat distribution, so that the part being placed in support plate 500 can uniformly be heated, annealing Effect is more outstanding.

Specifically, 510 bottom of pillar is fixed with bottom plate 520, the refractory brick 300 of 200 bottom surface of furnace chamber is equipped with two in parallel Guide rail 530, guide rail 530 towards 600 direction of fire door extend, the opposite side side wall of two guide rails 530 be equipped with groove, bottom plate 520 edges can be caught in the groove, when it is desired to be used, need to be only caught in bottom plate 520 in groove and be slid into furnace chamber 200 It uses, when disassembly is desired, can be taken off as track skids off fire door 600 i.e., it is convenient for disassembly and assembly, it is practical flexible.

It takes for convenience, pillar 510 uses the hollow cylinder of metal material to mitigate weight and reduce operating pressure.

In summary, when the utility model is used, first sliding into supporting mechanism by guide rail 530 from fire door 600, It is heated again toward the part that placement in the support plate 500 of guide rail 530 is annealed, since support plate 500 is located at burner hearth Middle part improves annealing effect so that part is able to thermally equivalent.

But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this Utility model, and being not used as the restriction to the utility model, if in the spirit of the utility model, to Variation, the modification of the upper embodiment will all be fallen in the Claims scope of the utility model.
