The working of an invention form
Below, describe example of the present invention with reference to the accompanying drawings in detail.
(example 1)
Fig. 6 is the diagrammatic sketch of an example of expression heat-treatment furnace of the present invention.This heat-treatment furnace is that the pottery system electronic component to piezoelectric element or magnetic element etc. burns till or the heat-treatment furnace of the heat treated of usefulness such as ungrease treatment.
As shown in Figure 6, this heat-treatment furnace has furnace body 3, it comprises uses body of heater of being made up of ceramic material that heat-barrier material constituted 1 and the siege portion 2 that constitutes with heat-barrier material, the barrel 4 of configuration muffle M in the furnace chamber L described later in this furnace body 3, the barrel 4 and the spatial portion between body of heater 1 inwall that have in furnace chamber L at muffle M produce the high hot heater 5 as thermal source.
As shown in Figure 6, body of heater 1 constitutes the tubular with top, the bottom opening of this body of heater 1.The inner space of the tubular structure in this body of heater 1 is the furnace chamber L of the barrel 4 of the described muffle M of configuration, and columnar this barrel 4 that hear resistance metal (for example stainless steel, alray 601 etc.) constitutes is configured to this furnace chamber L concentric.This barrel 4 has top 4a, and bottom opening, and the lower end of this barrel 4 extends to the below of the bottom opening of body of heater 1, and this lower end becomes the state that puts on pedestal part 6 described later.
And at the bottom opening position of this barrel 4, the mounting table part 2A of lifting siege portion 2 freely can enter.Promptly, siege portion 2 usefulness heat-barrier materials constitute integratedly discoid base portion 2B and in the central portion form and to protrude columned mounting table part 2A upward, simultaneously, the roughly the same mounting table part 2A of the internal diameter of external diameter and barrel 4 just enters in the barrel 4 by the rising of siege portion 2.Mounting table part 2A is provided with at the bearing 8 that is suitable for being used under the state of heat treated depositing in advance as the heat proof material system of many ceramic electron elements of object being treated 7.
In addition, the spatial portion between barrel 4 and body of heater 1 inwall is arranged a plurality of bar-shaped heaters 5 along barrel 4 concentric circumference with predetermined distance ground.These heaters 5 are from the outside supply capability of body of heater 1, the thermal source when becoming heat treated.In addition, on the 4a of the top of barrel 4, connecting gas supply pipe 10 and blast pipe 11 with sealing state.The atmosphere gas that heating clamber 4 is held in gas, for example nitrogen or argon gas etc. that the atmosphere that is suitable for degreasing process and total firing process uses supplies in the heating clamber 4 by the never illustrated gas supply source of this gas supply pipe 10.
Muffle M as previously mentioned, it comprises columnar barrel 4 and the pedestal part 6 with top 4a.Pedestal part 6 to be putting state support barrel 4, and this pedestal part 6 is again by fixed bearing portion 12 fixed bearings, and lower side is sealed to be fixed on described siege portion 2 is bearing on the discoideus supporting station of using on the lowering or hoisting gear 13.That is, to shown in Figure 8, pedestal part 6 comprises as Fig. 6: have the up/down perforation center and with the discoideus member 15 in the hole 14 of the roughly the same diameter of external diameter of barrel 4; Following integrally welded cylindrical body 16 with this discoideus member 15, the containment member 17 that is made of the ring-type silicon sponge that is located on the supporting station 13 is close to the lower edge of cylindrical body 16 along with the rising of supporting station 13, thus, the space that is surrounded by pedestal part 6, supporting station 13 etc. becomes closed state.
And the barrel 4 of muffle M is, by clamp stable on heating ring-type liner 18 (for example being ceramic substrate, carbon liner of silicone cushion, sheet etc.) and put the discoideus member 15 that is bearing in pedestal part 6 above.In detail, from the lower end of barrel 4 to the marginal portion of radial outside enlarged-diameter put annular flange portion 19 full week, this annular flange portion 19 is welded on the marginal portion of barrel 4 lower ends.And the lower end edge portion of barrel 4 divides full Zhou Zaifang on liner 18.Liner 18 is set as ring-type along hole 14 edge in the discoideus member 15.So, barrel 4 is bearing on the pedestal part 6 by liner 18, and this pedestal part 6 puts by containment member 17 and is bearing on the supporting station 13, just can guarantee the air-tightness of the spatial portion of heating clamber 4 and 2 configurations of siege portion.Here, the lower end edge portion of barrel 4 directly contact is described in front by the structure that is pressed on the liner 18, pushes liner but also can make with the such member that becomes one with barrel 4 of above-mentioned annular flange portion 19 with the pressing member of barrel 4 splits.
In addition, be to improve the air-tightness between barrel 4 and the pedestal part 6, setting by liner 18 with barrel 4 by the pressing mechanism 20 that is pressed on pedestal part 6 sides.To shown in Figure 8, is center and 4 this pressing mechanisms 20 (wherein 2 not shown) be configured to symmetric position with axle center P as Fig. 6, makes pressing force below barrel 4 effects that circumferentially act on equably of axle center P relatively.As shown in Figure 8, each pressing mechanism 20 comprises: as the swing arm 22 of power transfering part, its around horizontal axis X and swinging be bearing in freely with the support 21 that is set as one above the discoideus member 15 on; Push service portion 23, it is roughly on the radially inner side end that can relative axle center P with the parallel axle center of horizontal axis X swingingly be bearing in this swing arm 22 radially and giving time thrust from the top down with under the state of described annular flange portion 19 butts; As the cylinder 24 of drive unit, its effect is that the radial outside end to swing arm 22 applies the power that pushes away upward.The interlinking lever end of this cylinder 24 can be bearing on the radial outside end of swing arm 22 with roughly centering on the axis swing parallel with horizontal axis X.In addition, also the linear actuator of usable oils cylinder pressure etc. constitutes drive unit and replaces this cylinder 24.But cylinder 24 is the members around X knee-action ground, axle center operation swing arm 22, when object being treated being burnt till heat treated such as processing, and when after this heat treated, object being treated being cooled off, for giving the power that the outboard end of swing arm 22 is mentioned upward on the liner 18 by being pressed in, to improve the air-tightness between barrel 4 and the pedestal part 6 with barrel semi-finals power.
Thus, in heating treatment step and refrigerating work procedure, service portion 23 purposes of pushing of the medial end of swing arm 22 are, keep the state that annular flange portion is pushed away for 19 times with certain power, and raising liner 18 reaches with barrel 4 and the compactness of pedestal part 6 improves air-tightness.And 25 are structures of being connected with cylinder 24 of the outboard end with swing arm 22 among the figure, promptly be to allow the floating junction of cylinder 24 at the lateral deflection of connecting rod.Among the figure, the 26th, for the spatial accommodation that forms liner 18 is erect the vertical flange part that is located at the ring-type on the discoideus member 15.
As mentioned above, muffle M is made of barrel 4 and pedestal part 6, the reason that makes airtight construction is, when the temperature of muffle M rises along with heat treatment operation, the barrel 4 of muffle M just is subjected to the power desiring to expand upward, and muffle integral body just is raised, therefore, relatively hot handles that furnace body is in the pedestal part of stationary state and the welding portion of barrel is subjected to stress, this part is cracked and can not guarantee air-tightness.Therefore, in above-mentioned example,, when barrel 4 has been applied the power that makes progress,, just offset the power that this makes progress by pushing back cylinder 24 though push down the annular flange portion 19 of barrel 4.In addition, the barrel 4 among the muffle M is also to radially expansion, but the displacement of swing arm 22 grades that this expansion produced is offset by floating junction.Thus, annular flange portion 19 just is not subjected to surpassing required load.
Below, the structure of the object being treated after the heat treated 7 and muffle M being cooled off usefulness rapidly is described.To shown in Figure 5, described body of heater 1 has made in about separately boundary face F can be divided into or the front and back in the up/down perforation hole by being used for connecting described gas supply pipe 10 and blast pipe 11 2 structure as Fig. 1.And each minute blow-on part 1A, the 1B that constitutes body of heater 1 is arranged to can leave mutually, closely moves, and also can leave, closely move relative to the barrel 4 of muffle M, simultaneously, is provided with and is used for carrying out the mobile drive unit of using that this moves.In addition, the vertical view when Fig. 3 represents the heat treated of body of heater 1, expression divides a blow-on part 1A, the incorporate state of 1B.Fig. 2 is the diagrammatic sketch that the body of heater 1 during with 7 coolings of muffle M and object being treated is overlooked expression, the state after branch blow-on part 1A, the 1B of expression body of heater 1 leaves mutually.Fig. 1 is the stereogram of body of heater 1 summary such as grade when representing described the cooling.
Specifically, each minute blow-on part 1A, 1B are fixed on support 27A, the 27B integratedly with the state of putting respectively, and the fixed frame W that surrounds body of heater 1 and states such as support 27A, 27B is set.Each support 27A, 27B are set as relative to the bottom surface and slidably move.And, as shown in Figure 4, on this fixed frame W of relative bottom surface stationary state, be provided with motor 28, transmit power, and the rotation of two ends separately that will rotate a pair of screw mandrel 29,29 that drives is bearing in freely on the fixed frame W from this motor 28.Each screw mandrel 29,29 is shown in Fig. 4 and Fig. 5 (omitting diagrammatic sketch such as muffle), and the screw thread guide part 30A, the 30B that are provided with on each support 27A, 27B with setting screw.In each screw mandrel 29, for the screwing on the screw thread guide part 30B with support 27B that screw on the screw thread guide part 30A that makes support 27A becomes opposite screw thread travel condition, the hand of spiral that will be formed at the ridge on a side and the opposite side from the central portion of screw mandrel 29 respectively makes rightabout.In addition, each screw mandrel 29,29 is configured in the next door of each minute blow-on part 1A, 1B bottom under the state that separates boundary face F quadrature of its screw thread rotation axis direction and each minute blow-on part 1A, 1B.And, when this screw mandrel 29 near motor 28 sides being carried out transmission of power, power is passed to another screw mandrel 29 from this screw mandrel 29 by being configured in the chain gearing in the fixed frame W with chain drive.Here, formations such as motor 28, screw mandrel 29,29, screw thread guide part 30A, 30B and chain drive move and use drive unit.
Utilize this structure, two screw mandrels 29,29 just are driven in rotation with synchronous regime.And, when making when leaving mutually between branch blow-on part 1A, the 1B, utilizing not shown switching manipulation to give artificial instruction makes motor 28 just change driving, two screw mandrels 29,29 and its interlock and rotate, along with this rotation, just be manipulated into mutually between screw thread guide part 30A, the 30B and leave, therefore, support 27A, 27B start become to leave mutually, further make branch blow-on part 1A, 1B start become to leave mutually.For example, utilize the limit switch (not shown) of photoelectric sensor etc. to detect branch blow-on part 1A or 1B and whether be in maximum and leave the position, stop when detecting when being in maximum and leaving the position, just motor 28 being controlled to automatically.On the other hand, when giving zoarium between branch blow-on part 1A, the 1B that will be in open state and carry out heat treated, by begin the sign on of closed action artificially to the zoarium input, then motor 28 just is reversed driving, two screw mandrels 29,29 and its interlock and direction of rotation counter-rotating on the contrary when opening, along with this rotation, screw thread guide part 30A, 30B are manipulated near each other, therefore, support 27A, 27B start become near each other, further make branch blow-on part 1A, 1B start become near each other, divide blow-on part 1A, 1B just fit.By to the detection of the overload state of the motor 28 that produces along with this zoarium etc. or utilize limit switch etc. to fit status detection, and motor 28 is controlled to halted state.In addition, should move with the driving control of drive unit and be undertaken by not shown control device, and make branch blow-on part 1A, 1B leave composition is not limited to artificially import sign on or halt instruction etc. from state or fit control form mutually, also can burn till the end of program according to the rules, automatically carry out start by control device and begin or stop.In addition, each heater 5 still moves together to be installed in the state on branch blow-on part 1A, the 1B, but also can make will divide blow-on part 1A, 1B to divide when opening can be with heater 5 from structure that minute blow-on part 1A, 1B break away from.
Utilize said structure, when in the heating clamber K that object being treated 7 is contained in muffle M, carrying out heat treated, body of heater 1 makes incorporate state in advance, when cooling off when the heat treated end and to object being treated 7, by artificial instruction etc., utilize to move each minute blow-on part 1A, 1B to be left respectively mutually with drive unit.Thus, owing to muffle M is exposed on the external for heating clamber K is exposed in the atmosphere under keeping airtight conditions, so by can promptly cooling off muffle M with the heat exchange of atmosphere.Therefore, the available short time is cooled to for example normal temperature to object being treated 7, can shorten refrigerating work procedure and whole activity time.
In above-mentioned example, shown body of heater to be divided into 2 structure, but also can make more than 3, and each minute blow-on part is left relatively mutually.
In above-mentioned example,, can make also that the part that will divide blow-on is fixed, only other parts make muffle be exposed to structure in the atmosphere to leaving a fixing side shifting of dividing blow-on though shown the structure that branch blow-on part is left mutually respectively.In addition, the method that should move also is not limited to the structure of the slip as above-mentioned example, for example, by do to become to resemble make so-called the splitting around the branch blow-on partly around axle center up and down relatively other minutes blow-on partly swing switching and the structure that muffle can be exposed on the external.In addition, also can utilize crane or forklift that the branch blow-on is partly moved with away from other stove parts.In addition, as the separable structure of body of heater, thereby also can make the structure that horizontal plane can be separated body of heater up and down as parting plane.As object lesson, also can be by the top of body of heater be partly separated and is made its rising with heater etc. or keeping under the state of heater etc. from side wall of furnace, thus muffle M is exposed on the external to be exposed in the atmosphere.
In above-mentioned example, disclose annular flange portion 19 be welded on 4 times ora terminalis of barrel and incorporate structure, but also can not weld, and when utilizing casting or machining etc. with integrated and form with the muffle body.
