Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
In the present invention, when not doing contrary explanation, the noun of locality such as " upper and lower, left and right " of use typically refers to reference to upper and lower, left and right shown in the drawings.
Processing method that is simple and the production torque product that cost is low for providing a kind of, the invention provides a kind of method of squeeze forming of torque product.Those skilled in the art to it should be understood that described " torque product " is a kind of inner large, the product that opening is little, see Fig. 1, this method of squeeze forming comprises the following steps:
Step one, provide the thin-wall part 1 that a kind of inner surface configuration is identical with described torque product inner surface configuration;
Step 2, provide the Split mold 2 that a kind of die cavity 3 is identical with the external surface shape of described torque product, the spreader 4 of this Split mold 2 is communicated in described die cavity 3 by multiple split channel 5;
Step 3, described thin-wall part 1 to be fixed in described die cavity 3, and to inject liquid to be processed in described spreader 4; And
After step 4, described liquid to be processed and described thin-wall part 1 cooling forming, take out the described torque product in described Split mold 2.
As total invention aim, produce torque product because of it and produce the interior shape how the product difference inner little, opening is large mainly obtains torque product, this is also that the present invention needs one of problem solved, as shown in Figure 1, in step, the Inner structural shape obtaining torque product conveniently, the invention provides the thin-wall part 1 that a kind of inner surface configuration is identical with required torque product inner surface configuration, then the inner surface of thin-wall part 1 is the inner surface of torque product.
The inner surface of torque product is obtained from above, next step is the outer surface how obtaining torque product, in step 2, a kind of Split mold 2 is provided, and the die cavity 3 of Split mold 2 is identical with the external surface shape of torque product, in addition, Split mold 2 is also provided with multiple split channel 5 and is communicated with die cavity 3, and multiple split channel 5 is connected to spreader 4.
In step one and step 2, obtain inner surface configuration and the external surface shape of torque product respectively, in step 3, be fixed in the die cavity 3 of Split mold 2 by there being the thin-wall part 1 of torque product inner surface configuration, and liquid to be processed is injected in spreader 4, liquid to be processed flows through multiple split channel 5 by spreader 4 and enters into die cavity 3.By the time described liquid cools to be processed shaping after, namely in step 4, then take out the torque product in Split mold 2.
Torque product is produced by above four steps, method of operating is simple, and because thin-wall part 1 cost is low, and then making the processing cost also step-down of whole technique; the inner surface configuration of thin-wall part 1 can be processed according to the inner surface configuration of required torque product; before not producing torque product; can process one or more torque product according to prior art combination casting, die casting, following process series of process, and then utilize the inner surface configuration of the torque product processed to process the moulding of thin-wall part 1.It should be noted that, do not limit the processing method of thin-wall part 1 herein, the moulding of the thin-wall part 1 that those skilled in the art adopt known method to process all meets the demands.
Under normal circumstances, the thickness range of thin-wall part 1 is 0 ~ 10mm, under preferable case, the thickness of described thin-wall part 1 is set to 0.5mm ~ 4mm, so both can save material, and the torque product produced can be made again lower containing the composition of thin-wall part 1, thus improve the purity of torque product.
In order to make in the inflow die cavity 3 of uniform liquid to be processed, in step 3, liquid to be processed flow into die cavity 3 by spreader 4 from multiple split channel 5 respectively, can ensure that the torque product internal stress of the shaping rear formation of liquid cools to be processed is identical so as far as possible, improves performance.
In a preferred embodiment, the manufactured materials of described thin-wall part 1 can be copper, aluminium, magnesium, titanium, as long as the fusing point of thin-wall part 1 is both passable higher than the fusing point of liquid to be processed, under preferable case, described liquid to be processed is molten aluminium alloy or magnesium alloy liquation, under preferable case, the material of thin-wall part 1 is copper, because the fusing point of copper is higher than the fusing point of magnesium and aluminium, can ensure that thin-wall part 1 is not melted when molten aluminium alloy or magnesium alloy liquation are injected in die cavity 3 like this, and then keep the complete of inner surface configuration, and molten aluminium alloy or magnesium alloy liquation can melt mutually with copper, namely described torque product is the integrative-structure of liquid described to be processed after cooling forming and described thin-wall part 1.
For catering to present inventive concept, produce the product having hatch frame, so thin-wall part 1 should be hollow structure.
Because liquid to be processed is molten aluminium alloy or magnesium alloy liquation, the mobility of molten metal is poor, although the external surface shape of thin-wall part 1 does not limit, and shaping after and liquid to be processed combine together, but the moulding of thin-wall part 1 may have some grooves or corner makes liquid to be processed to enter completely, so merge with thin-wall part 1 to ensure that liquid to be processed is as much as possible, the space that thin-wall part 1 and die cavity 3 are formed is evacuated herein, liquid to be processed like this enters in the process of die cavity 3 and can produce certain pressure, so namely, liquid to be processed and thin-wall part 1 can be allowed to realize more fusion.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible combination.
In addition, also can be combined between various different embodiment of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
