Abstract
The utility model discloses an extrusion-resistant and friction-resistant furnace door of a holding furnace. According to the furnace door, on the basis of an existing furnace door which is sealed simply through packing, an improvement is further conducted. First of all, the bottom edge of the furnace door is provided with a circle of rectangular groove which is 2 centimeters wide and 1.5 centimeters deep, wherein square asbestos packing which is 2.5 centimeters wide is installed in the groove, 12 threaded holes are formed in the side face of the groove in a circle, and the threaded holes are used for fixing the packing to prevent the packing from falling off. At the time of installation, firstly, the packing is placed in the groove; secondly, 12 bolts are used for fixing the packing; thirdly, high-temperature-resistant cement is integrally poured to the middle portion of the furnace door to replace a high-temperature-resistant material which is used frequently in the prior art, and the problem that frequent opening and closing operation makes the material prone to falling off is solved; fourthly, four holes are formed in the four corners at the bottom of the furnace door respectively, wherein the diameter of each hole is 2 centimeters, four bolts are fixedly installed on the corresponding portions of the furnace door, and through matching between the round holes and the bolts, the furnace door is prevented from moving vertically in the closing process. Due to the design, the furnace door has the advantages that the sealing performance is good, and the packing is not prone to falling off and damage.
Description
Technical field
The utility model relates to aluminum wheel of vehicle low pressure casting equipment field, relates in particular to the holding furnace fire door of a kind of resistance to extruding, rub resistance.
Background technology
Holding furnace is the vitals of aluminum wheel of vehicle casting process mesolow casting machine, fire door is as the part of holding furnace, the not only heat insulating ability important to aluminium liquid, and whether the stability of low pressure casting process pressure and production are had to important impact smoothly.For realizing better sealing and insulation, aluminium wheel hub industry generally adopts silicic acid asbestos board or fire door edge that one deck groove is set now, puts asbestos packing and seal in groove.Although it is better to adopt silicic acid asbestos board to seal effect, can often add a secondary aluminium liquid, open a fire door and all need to change an asbestos board, production cost is very high; Simple way of placing packing in groove, often because the frequent switch of fire door, sideslip cause coming off of asbestos packing and damage, and often make sealing property not reach requirement owing to placing simply packing in groove, not only affect the temperature of aluminium liquid, and cause the pressure transient of casting machine, even adding through being everlasting needs to rise temperature after aluminium liquid and produces, has had a strong impact on production efficiency.
Summary of the invention
The utility model object is to overcome existing silicic acid asbestos board and packing_seal to carry out the shortcomings such as holding furnace fire door insulation cost is high, sealing effectiveness is poor, and the sealing device of a kind of resistance to extruding, rub resistance is provided.
The concrete technical scheme that realizes above object is: the holding furnace fire door of a kind of resistance to extruding, rub resistance, this fire door existing with having carried out further improvement on simple packing_seal basis, first open at fire door bottom margin that a circle is wide 2 centimetres, the rectangular recess of dark 1.5 centimetres, the square asbestos packing of wide 2.5 centimetres is installed in groove; Within one week, make a call to 12 screw holes in the side of groove and prevent that for fixing packing it from coming off.When installation, first packing is placed in groove, then with 12 bolts, packing is fixed; Secondly adopt high temperature resistant cement one-piece casting in middle part of fire door, with the exotic material that replaces used to use, play and prevent from causing the caducous problem of material because of switch frequently; Again beat 4 circular holes of 2 centimetres of diameters four jiaos of fire door bottoms, at corresponding 4 bolts of body of heater position fixed installation, prevent the up and down play of fire door in closing process by the cooperation of circular hole and bolt, there is the feature of good airproof performance, packing difficult drop-off and damage by the fire door of above design.
Accompanying drawing explanation
Fig. 1 is fire door front elevation of the present utility model.
Fig. 2 is the sectional drawing of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, the holding furnace fire door of a kind of resistance to extruding, rub resistance, have at the edge of this fire door main body 1 that a circle is wide 2 centimetres, the rectangular recess 2 of dark 1.5 centimetres, the square asbestos packing 3 of wide 2.5 centimetres is installed in groove (2), within one week in groove 2, be drilled with 12 screw holes and be used for fixing asbestos packing 3, beat 4 circular holes 5 of 2 centimetres of diameters four jiaos of fire door bottoms, at corresponding 4 bolts 4 of body of heater position fixed installation, prevent the up and down play of fire door in closing process by the cooperation of circular hole 5 and bolt 4.
