Abstract
The present invention relates to a lift-controllable rotary vacuum pressurizing cast furnace. A furnace body is provided with a water-cooled jacket; the whole furnace body is split into three segments; all the segments are tightened and sealed by flanges. The top of the furnace body is provided with a powerful cooling ventilation hole and a bursting disc; one side of the furnace body is provided with an upright post connected with an upper furnace body; a manual lifting jack is arranged in the connecting position; a leading screw for hanging a casting mold is controlled by a transmission device to move up and down. At the beginning of casting, a tightening clamping ring is unscrewed, the lifting jack jacks up the upper furnace body, and the upper furnace body is rotated to install the casting mold. The present invention has the advantage of convenient operation; besides, the furnace body can be optionally lengthened.
Description
The present invention relates to a kind of life-controllable, rotary vacuum pressurizing cast furnace.
The compression casting technology of utilizing the pressure permeation stove to implement multiple fiber is to make the big stove of a band water collar in decades always, and preheating tube furnace and aluminum melting crucible stove place in the stove, then to big stove compression casting.Especially the most representative with the manufacturing technology and the furnace binding of Massachusetts Institute Technology.Yet, structure with regard to its body of heater itself, be to utilize a big tank-like body mostly as body of heater, cold water jacket is arranged outward, during processing parts, need from the top of body of heater workpiece to be put into stove, for the part of processing different size, the body of heater that will make different size is to adapt to the casting process of its casting workpiece.So just caused complexity on the operating procedure and body of heater adaptability, and the expense of making a body of heater again also is comparatively expensive to product.
The objective of the invention is, reduce the complexity of operating procedure, strengthen the adaptability of body of heater product.
Technical solution of the present invention is, divide three sections with whole body of heater, top cover and upper furnace body ring flange tighten up with the screw sealing, upper furnace body and lower furnace body ring flange tighten up sealing with snap ring, a strong cold air vent and a rupture disk are arranged at the top of body of heater, one side of body of heater has a column to be connected with upper furnace body, and a manual jack is set below its junction, the top of body of heater have one by transmission device control, can the upper and lower mobile leading screw of hanging mold.During blow-on, open the fastening snap ring of upper furnace body and lower furnace body, with jack upper furnace body jack-up, rotate upper furnace body itself and lower furnace body are misplaced, install and hang mold, afterwards, again upper furnace body is rotated back into original position, put down with lower furnace body and tighten up sealing with snap ring, after treating preheating, vacuumizing, the leading screw that will hung mold by transmission device is lowered to compression casting in the crucible furnace.
The invention has the advantages that body of heater divides three sections to finish, therefore, can increase the furnace chamber volume according to the workpiece size of the being cast body of heater that arbitrarily extends.Upper furnace body jack-up, rotation can bring convenience to operation, in addition, owing to installed strong cold ventilating opening and rupture disk additional, so reduced the interfacial reaction of fiber and matrix, makes that operation is safer.
Be illustrated as the schematic diagram of foundry furnace.
The casting body of heater divides upper furnace body (3) and lower furnace body (10), and the skin of body of heater is a water collar, interiorly makes with corrosion resistant plate.Stove contains foundry goods preheating tube furnace (5) and matrix fusion crucible stove (6), and body of heater top cover and upper furnace body (3) ring flange joins with bolt, when needs lengthening body of heater height, only needs can strengthen furnace height at this welding the preceding paragraph steel plate.Because upper furnace body (3) all need be opened when placing and take out workpiece with lower furnace body (10), and is easy and simple to handle for making,, the employing of the fit sealing of upper furnace body (3) and lower furnace body (10) ring flange tightens up so tightening up snap ring (7).Rupture disk (4) is installed at the top of bell, and the air pressure in stove increases suddenly, and when leaking when can't be from safety valve anxious, rupture disk (4) just can open automatically and quick-friedly lose heart.One side of foundry furnace upper furnace body is positioned at and sits column on one side at the bottom of the body of heater and link to each other with one, make upper furnace body to do 180 ° of rotations around column, under the link of upper furnace body and column, settle a manual jack (13), it can be upper furnace body jack-up, promptly make upper furnace body and lower furnace body remove, be convenient to the loading, unloading mold.
During the casting blow-on, open snap ring (7), with jack (13) jack-up upper furnace body 50mm height, with bolt (12) positioning and fixing, rotate upper furnace body (3), upper furnace body (3) and lower furnace body (10) are removed, then mold is installed on the feeding rod (2), utilize transmission device (1) to make the preprocessing workpiece place preheating tube furnace (5), again upper furnace body (3) is rotated back into original position and lower furnace body (10) tightens up with snap ring (7).Then, water filling in cold water jacket.Open valve (8), start vavuum pump (9), make vacuum reach 9 * 10 vacuumizing in the body of heater
-2-5 * 10
-2Holder send electricity heating for simultaneously tube furnace (5) and crucible furnace (6).After mold reached preheat temperature, and crucible furnace (6) endobasal-body melts, Electric Machine Control transmission device (1) descended feeding rod (2), and mold is sent in the aluminum melting crucible stove (6).Stop to vacuumize this moment, closes and vacuumize valve (8), opens aerating device (14), and inflation pressurization in stove makes the interior negative pressure of stove be raised to malleation, and pressure can reach 25-30kg/cm
2, pressure kept after 1-2 minute, promotes feeding rod (2) mold is proposed crucible furnace (6), rose to be back in the tube furnace (5), and tube furnace (5) and crucible furnace (6) have a power failure.Open venting valve (18) and make body of heater internal gas pressure balance this moment, opens snap ring (7), jack (13) jack-up upper furnace body (3), and mold has been got in displacement.Upper furnace body (3) resets, and continues to vacuumize, and keeps water-cooled, and when upper and lower furnace body temperature dropped to rated value, the stop pumping vavuum pump stopped cooling water, and casting finishes.
Claims (2)
1, a kind of life-controllable, rotary vacuum pressurizing cast furnace with cold water jacket, it is characterized in that, whole body of heater is divided into three sections, top cover is educated the upper furnace body ring flange and is tightened up with the screw sealing, upper furnace body and lower furnace body ring flange tighten up sealing with snap ring, a strong cold air vent and a rupture disk are arranged at the top of body of heater, one side of body of heater has a strong cold air vent and a rupture disk, the individual column that has of body of heater is connected with upper furnace body, a manual jack is set below its junction, and the top of body of heater also has one by passing can going up of device control, the mobile down leading screw of hanging Zhu Mo.
