Description
Technical field
This utility model relates to field of powder metallurgy, is specifically related to a kind of high-performance home appliance compressor flange.
Background technology
Flange (flange) is a kind of discoid part, it is one of parts important on home appliance compressor, current ring flange is when making, flange production technology is broadly divided into forging, casts, the system of cutting, rolls these four, (1) cast flange: casting flange out, has pore, crackle, is mingled with in product；Cast-internal flow of tissue line style poor (if cutting members, streamlined worse) (2) forged flange: Forging Technology is improper, and also to there will be crystal grain big or uneven, and solidification cracking phenomenon, forging cost is higher than cast flange；(3) preparation method is cut blue: on middle plate, directly cut out the internal-and external diameter leaving processing capacity and the disk of thickness of flange, carry out the processing of bolt hole and waterline again, the less flange of size (4) can only be produced and roll flange: in Yong, plate cuts strip and then rolls into round technique and be called and roll, and is only used for the production of some large-sized flanges；For this, there has been proposed the process of powder metallurgy, it is to use metal or with metal dust (or mixture of metal dust and non-metal powder) as raw material, through shaping and sintering, manufactures metal material, is combined and the Technology of all kinds goods；Powder metallurgy has chemical composition and machinery, the physical property of uniqueness, and these performances are cannot to obtain with traditional casting method；It is a kind of few without Cutting Process, it is possible to reduce alloying component segregation to greatest extent, eliminate thick, uneven cast sturcture.
Utility model content
This utility model purpose is to provide a kind of high-performance home appliance compressor flange to overcome the deficiencies in the prior art, be not only easily worked, production cost low, and binding face smoothed precision is high, be beneficial to the Powder metallurgy flange of sealing.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of high-performance home appliance compressor flange, including flange body, described flange body is provided with central shaft hole, being provided with multiple installation through hole between circumference outer and the circumference outer of described central shaft hole of described flange body, described installation through hole is positioned on the same circumference in described flange body；It is fixedly connected with elastic wear-resisting layer on described central shaft hole inwall, described elastic wear-resisting layer is provided with flange in described central shaft hole end, described flange forms an annular boss in described central shaft hole circumference outer, and described annular boss end face is interval with multiple circular orientation groove；Described flange body material is powder metallurgy.
Improving further as this utility model, the internal diameter of described annular boss is less than the internal diameter of described central shaft hole, in the flange body between described central shaft hole and described installation through hole of the circumference outer of described annular boss.
Improving further as this utility model, described annular boss circumference outer is provided with chamfering.
Improving further as this utility model, the upper bottom face of described circular orientation groove is arc shape.
Improving further as this utility model, the installation through-hole wall of described flange body is fixed with elastic wear-resisting layer.
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that
This utility model scheme provides a kind of high property home appliance compressor flange, during flange body uses Simulations of Powder Metallurgy Compaction, by installing the elastic wear-resisting layer that elastic abrasion-proof material is made in the flange body central shaft hole made at powdered metallurgical material, elastic wear-resisting layer flange forms an annular boss in flange body central shaft hole end face circumference outer, seal between flange assembly and be located by connecting, improve sealing effectiveness, also can stop the flange body landing from elastic wear-resisting layer separated with elastic wear-resisting layer simultaneously, so that flange assembly is ensureing self-strength, while rigidity, the sealing property of raising method flange assembly, anti-wear performance and security performance, and improve the work efficiency of compressor.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solutions of the utility model are described further:
Accompanying drawing 1 is a kind of high-performance household electrical appliances flange structural representation of the present utility model；
Accompanying drawing 2 is a kind of high-performance household electrical appliances flange arrangement top view of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Described in the utility model a kind of high-performance household electrical appliances flange structural representation as shown in accompanying drawing 1,2, including flange body 1, flange body 1 is provided with central shaft hole 2, it is provided with multiple installation through hole 3 between circumference outer and the circumference outer of central shaft hole of flange body 1, through hole 3 is installed and is positioned on the same circumference in flange body 1；Being fixedly connected with elastic wear-resisting layer 4 on central shaft hole 2 inwall, elastic wear-resisting layer 4 is provided with flange 5 in central shaft hole 2 end, and flange 5 forms an annular boss 6 in central shaft hole circumference outer, and annular boss 6 end face is interval with multiple circular orientation groove 7；Flange body 1 material is powder metallurgy, and flange body 1 is the powder metallurgy layer 8 formed by powder metallurgy pressing；The internal diameter of annular boss 6 is less than the internal diameter of central shaft hole 2, in the flange body 1 between central shaft hole 2 and installation through hole 3 of the circumference outer of annular boss 6；Annular boss 6 circumference outer is provided with chamfering 9, so that boss is smoother, and more convenient operation during installation；The upper bottom face of circular orientation groove 7 is arc shape 10, it is simple to location contact stress is excessively concentrated, and is prevented effectively from annular boss and is easily broken abrasion；Installation through hole 3 inwall of flange body 1 is fixed with elastic wear-resisting layer 4；During flange body uses Simulations of Powder Metallurgy Compaction, by installing the system elastic wear-resisting layer that elastic abrasion-proof material is made in the flange body central shaft hole made at powdered metallurgical material, elastic wear-resisting layer flange forms an annular boss in flange body central shaft hole end face circumference outer, seal between flange assembly and be located by connecting, improve sealing effectiveness, also can stop the flange body landing from elastic wear-resisting layer separated with elastic wear-resisting layer simultaneously, so that flange assembly is ensureing self-strength, while rigidity, the sealing property of raising method flange assembly, anti-wear performance and security performance, and improve the work efficiency of compressor.
