Abstract
The present invention relates to a loading mechanism for transmitting a material basket in a heat processing furnace, which is composed of at least one chain operating on a guiding track, wherein the chain extends into the heat processing furnace. On the side close to the furnace, a chain section is provided with a swinging rod, and a supporting rod is fixed on the swinging rod. The ascendant and the descendant of the supporting rod are completed by a supporting baffle and a disconnection preventing tenon.
Description
The present invention relates to a kind of charge mechanism that transmits charging basket in heat-treatment furnace, it is made up of the chain that one or several drives charging basket.Chain is moved on guide rail by chain wheel drive, and it is made up of the single chain sheet that has roller.
Usually, heat-treatment furnace is made up of a high-temperature region and a loading platform.In addition, have cooling and quench zone, in each case, these districts separate with door each other.
The charge mechanism of such heat-treatment furnace has been known.In these mechanisms, chain is moved on guide rail by chain wheel drive, and the drive charging basket passes through treatment region.On chain, use tenon or block to come and the charging basket engagement, transmit with realization.
The above-mentioned the sort of charge mechanism that is used for heat-treatment furnace can be recognized from DE-AS1279706.In the mechanism that this document is narrated, chain is made up of the single chain link that has wheel, and transporting then of charging basket finished by tenon.Yet also there is disadvantage in this mechanism, and promptly charging basket can not directly be sent in the stove, but must put down in advance, and traction is by rail and/or stove firebrick structure then, and this may influence the life-span of charging basket significantly.
Therefore, the object of the present invention is to provide a kind of charge mechanism that transmits charging basket in heat-treatment furnace, it is made of the chain that one or a few drives charging basket, and chain is moved on guide rail by chain wheel drive, and it is made up of the single chain link that has roller.This device can directly be placed on charging basket their precalculated position, also can take out from stove again.
The present invention utilizes following method to realize this purpose:
Guide rail is extended in the heat-treatment furnace:
A pair of swing arm to up is housed on that end of chain tendency heat-treatment furnace in all cases, above the axle of chain link, is provided with some support bars in the end of swing arm; Its length is substantially equal to the length of charging basket.
On chain, at the end of the chain link that has support bar, be rotated away from that end of heat-treatment furnace, nestle up the back of last swing arm, one spacer is housed.Last in all cases support bar part all is equipped with one prevents out of joint.
Support bar is preferably carried by two or three chain links in all cases.In addition, if first is provided with a roller with last support bar in its outer end; That will be very helpful.
This chain can directly apply to heat-treatment furnace, yet it is more favourable that they are applied to a kind of charging car.This charging car drives one or several swing mechanism, and this mechanism is meshed with oscillating cam on each swing arm.In addition, this mechanism is provided with the bool by elastic reaction in the support bar side, and bool is to upper process and exceed more than the level of support bar.
This charge mechanism advantage is that the charging basket unloads from pedestal, and is placed directly on the preposition, need not to place it in tractive on rail or the heating furnace firebrick structure and mistake, thereby needn't stand big tension and bending stress.The latter with life-span of appreciable impact charging basket especially under the high situation of heat treatment temperature.
Fig. 1 to 4 is by an embodiment illustrative charge mechanism of the present invention.
Fig. 1 is a vertical view, and Fig. 2 is the longitudinal section by a chain center, and Fig. 3 is the cross-sectional view by chain center A-A along the line.
Charge mechanism is made up of two chains (1).Chain (1) is driven at guide rail (14) by sprocket wheel (8) and goes up operation.Guide rail (14) both had been placed on the charging car (15), also was placed in the workspace of heat-treatment furnace (16), and was subjected to the restriction of safety catch (12).Chain (1) is made up of single chain link (2), and roller (9) is housed in the chain link both sides.Swing arm (3) is fixed on the axle (7) of chain link (2), and drives support bar (4).Support bar (4) outer end portion respectively is equipped with a roller (5).When support bar rose and reduce, roller can be in safety catch surface flexible motion.The size of support bar (4) is decision like this, and promptly they all can form a continuous brace summer rising and the reduction state.Prop up spacer (6) and be firmly connected on the chain (1), it is positioned at the end that heat-treatment furnace is left in chain (1) running, and follows the back in last swing arm (3).In addition, on last support bar (4), also be fixed with one anti-(7) out of joint.
Oscillating cam (10) is housed on one or several swing arm (3).Swing mechanism (11) can with each cam-engaged.The support bar (4) that this mechanism can make supported retaining (6) raise reduces, and swing arm (3) tilts to opposite side simultaneously.Swing mechanism (11) is gone up and near place, support bar side a bool (13) is being housed, and it raises up and exceeds these support bars.Thereby in the time of on charging basket being installed to support bar (4), bool (13) is pressed downward, thereby swing mechanism can not entry into service.
Use the method for charge mechanism as follows:
In the time of in charging basket being sent to heat-treatment furnace (16), this charging basket is to be positioned on the charging car (15).Chain (1) is driven by sprocket wheel (8) and passes through under charging basket, and support bar (4) is supported by chain link (2).After a spacer (6) passes through sprocket wheel (8), then chain link transfers horizontal level to by the upright position near it, and a spacer (6) is pressed onto on the bar (S), causes that support bar (4) rises, even charging basket rises, charging basket is admitted to and is placed in the heat-treatment furnace (16) like this.This finishes by anti-(17) out of joint, and in corresponding mechanism, this prevents locking fire door out of joint and when chain (1) reverses, make support bar (4) upset that like this, these bars can also be supported on the chain link (2).
When from heat-treatment furnace (16), taking out charging basket, the support bar (4) that supported retaining (6) raises, when crossing swing mechanism (11) by being meshed with oscillating cam, it just is supported on the chain link (2), and is brought to below the charging basket.Go up when rolling when the roller (5) of front support bar is pressed in fixing block (12), support bar (4) rises, and charging basket is risen, and is able to taking-up from heat-treatment furnace (16).Rotate to the upright position when propping up a spacer (6), support bar has just lost support, therefore, just lowers, and charging basket is placed on the charging car (15).
