Description
Technical field
The present invention relates to a kind of processing method and device of saddle-shape lining part, belong to saddle-shape lining part processing technique field.
Background technology
Along with extensive utilization and the fast development of lining part, production firm has developed the lining part of all styles of.Lining part as shown in Figure 6 is exactly a kind of saddle-shape lining part commonly used, and its structure is saddle-shape, and two ends are the horn mouth shape, do not seal on the circumference, and an opening is arranged vertically.At present, in the prior art, often adopt copper tube to process this saddle-shape lining part with the mode that special roll unit carries out rolling forming, the mode of production that the special roll unit of this employing carries out roll extrusion, its shortcoming is that technique more complicated, equipment investment are large, production cost is higher, is only suitable in the little employing of situation that batch is large, part specifications is few.The situation few for production quantity, that part specifications is many, the mode of this roll extrusion just is not suitable for very much.Because the structure of saddle-shape lining part is comparatively complicated, the particularly difficult realization of the technique of closing in, flange, and its part requires surfacing, smooth, no wrinkle, impression, scuffing, therefore adopt existing common apparatus to carry out processing, the surface quality of its product is difficult to be guaranteed, so the processing mode of existing production saddle-shape lining part is not ideal.
Summary of the invention
The objective of the invention is: provide a kind of small investment, cost low, simple in structure, easy to operate, safe and reliable, can guarantee product quality, can enhance productivity and be suitable for the saddle-shape lining part production of plurality of specifications and be suitable for processing method and the device of the saddle-shape lining part of in enormous quantities or small lot batch manufacture again, to overcome the deficiencies in the prior art.
The present invention is achieved in that the processing method of a kind of saddle-shape lining part of the present invention is, it is raw material that the method adopts sheet metal, specification according to the saddle-shape lining part of made is carried out blanking, then the sheet metal of lower honest material is bent into the blank of drum, the blank that is bent into drum is enclosed within on the saddle-shape formation die core that is combined into by left core rod and right core rod, the external surface shape of this saddle-shape formation die core is identical with the inner surface configuration of the required saddle-shape lining part that is processed into, then produce a saddle-shape mould that is combined into by upper die and lower die, be provided with shaping groove at upper die and lower die, when the upper die and lower die of this saddle-shape mould are combined, the surface configuration of the shaping groove that it is combined is identical with the external surface shape of the required saddle-shape lining part that is processed into, then cover is had in the shaping groove of the counterdie that is placed on the saddle-shape mould on the saddle-shape formation die core of blank, again patrix is closed, can by to the exerting pressure of patrix, pass through patrix like this, the acting in conjunction of counterdie and saddle-shape formation die core and the blank of drum is pressed into the shape of required saddle-shape lining part.
The processing unit (plant) of the of the present invention a kind of saddle-shape lining part that makes up according to said method is: this device comprises base, be connected by screw counterdie at base, be provided with patrix at counterdie, on counterdie and patrix, all be respectively equipped with shaping groove, and the surface configuration of the shaping groove when counterdie is combined with patrix is identical with the external surface shape of the required saddle-shape lining part that is processed into, be provided with the columned saddle-shape formation die core that is combined into by left core rod and right core rod in counterdie and the formed shaping groove of patrix, the external surface shape of this columned saddle-shape formation die core is identical with the inner surface configuration of the required saddle-shape lining part that is processed into.
Above-mentioned base is the U-lag structure, and counterdie is arranged in this U-lag, and an axial locating surface that face is the saddle-shape formation die core in two parallel vertical faces of U-lag.
Distance between two parallel vertical faces of the U-lag of above-mentioned base is greater than 0.05～0.3 millimeter of the length of the saddle-shape formation die core that is comprised of left core rod and right core rod.
Be respectively equipped with the part positioning step at above-mentioned left core rod and right core rod.
Above-mentioned patrix is by being installed in the straight pin positioning and guiding on the counterdie and being connected with counterdie.
At above-mentioned straight pin cover spring is arranged.
Owing to adopted technique scheme, it is raw material that the present invention adopts sheet metal, greatly reduce production cost, and adopt the saddle-shape formation die core that is combined into by left core rod and right core rod and forms a processing unit (plant) that is specifically designed to the knockdown saddle-shape lining part of processing saddle-shape lining part by the saddle-shape mould that upper die and lower die are combined into, this device not only can be used on traditional press device, and can be directly by manually carrying out pressing operation.In addition, saddle-shape mould and the saddle-shape formation die core that is comprised of upper and lower mould of the present invention is the split mode, the realization of the complicated technology such as this not only is conducive to close up, flange, and the demoulding pickup of being more convenient for, be convenient to putting of part.The saddle-shape formation die core adopts the design of left and right core rod simultaneously, has further made things convenient for the charge and discharge operations of part.Base of the present invention is made into the structure of U-lag, and bottom width is greater than counterdie and patrix, has not only increased the contact area with the lathe table top, because vibration can make the situation of its overturning occur, has improved security and stability when effectively having prevented lathe work; And by the U-lag structural limitations relative position of counterdie and left and right core rod, left and right core rod play when preventing from being shaped, the unequal contraction of material when having avoided shaping, this forming quality for the assurance part has important effect.The design of the part positioning step of left and right core rod is carried out spacingly when being shaped to upper and lower mould, avoided because upper and lower mould contact part to be processed, and made the surface be subject to cut, pull infringement, thereby improved the quality of piece surface.Upper and lower mould adopts straight pin to connect, and has the function of location and guiding, the operating position precision of upper and lower mould when being conducive to guarantee to be shaped.In sum, the present invention compared with prior art, the present invention not only has small investment, advantage that cost is low, but also has the advantages such as simple in structure, easy to operate, safe and reliable; Adopt the present invention can guarantee product quality, can enhance productivity again, and the present invention not only is suitable for the production of the saddle-shape lining part of plurality of specifications, and is suitable for the needs of in enormous quantities or small lot batch manufacture.When carrying out small lot batch manufacture, the present invention only needs to get final product with manually suppressing without any need for press device.
