Embodiment
With reference to Fig. 1, a kind of bimetallic alloy hammer precoated sand manufacture method that the present invention proposes, comprises the following steps S1��S7.
S1, adopt first metallic substance make hammer handle 2.
With reference to Fig. 2, Fig. 4, hammer handle 2 adopts the layer method of watering to cast, and concrete steps are as follows:
S11, with reference to Fig. 3, adopting precoated sand legal system to make hammer handle sand mold 20, hammer handle sand mold 20 is provided with pouring hole 201, pouring hole 201 was hole, and make can insert pouring hole 201 emit cup 21;
S12, with reference to Fig. 5, multiple hammer handle sand mold 20 is stacked, and blocks the pouring hole 201 of lowest layer hammer handle sand mold 20, the pouring hole 201 that cup 21 will be emitted to insert most top layer hammer handle sand mold 20;
S13, the 2nd casting die is utilized to be fixed by hammer handle sand mold 20;
S14, by emitting cup 21 to pour into a mould the first metallic substance to hammer handle sand mold 20, the first metallic substance is filled each layer of hammer handle sand mold 20 by pouring hole 201 and is condensed into hammer handle 2;
S15, dismounting hammer handle sand mold 20, collect hammer handle 2.
In present embodiment, the layer method of watering is utilized to cast, can a large amount of hammer handle 2 of disposable production, it is to increase production efficiency. In addition, utilize the fixing sand mold of the 2nd casting die that the hammer handle 2 that in casting process, hammer handle sand mold 20 displacement causes can be avoided to be out of shape before cast, to improve conforming product rate.
In present embodiment, hammer handle sand mold 20 is one go out two sand molds, single hammer handle sand mold 20 is provided with two hammer handle die cavities, and pouring hole 201 is arranged in the middle part of sand mold between two hammer handle die cavities, so that the first metallic substance is flowed among two die cavities uniformly by pouring hole 201, be conducive to ensureing with batch hammer handle 2 greater homogeneity produced. When specifically implementing, hammer handle sand mold 20 can be designed to be one go out one or one and go out many sand molds according to actual needs.
In present embodiment, 2nd casting die is arranged on above most top layer hammer handle sand mold 20, and the hammer handle sand mold 20 layering stacked applies downward pressure, expands after avoiding the first metallic substance to be poured in hammer handle die cavity, adjacent hammer handle sand mold 20 is shifted, reduces hammer handle 2 production qualification rate.
S2, with reference to Fig. 6, adopting and penetrate sand machine and manufacture tup sand mold 10, tup sand mold 10 is divided into housing 11 and sprue cup 12, is provided with through hole 111 bottom housing 11, sprue cup 12 can be arranged on housing 11 top and with housing 11 inner space.
Housing 11 is hollow structure, and its inside is set to tup die cavity. In addition, through hole 111 diameter is greater than hammer handle 2 first end width, is less than hammer handle 2 the 2nd end width.
S3, being fixedly mounted by housing 11, by hammer handle 2 first end through housing 11 bottom through-hole 111, it is inner that hammer handle 2 the 2nd end is connected to housing 11. Housing 11 can refer to Fig. 7 with the assembling of hammer handle 2.
With reference to Fig. 8, in step S3, housing 11 avoids its displacement to cause cast not complete smoothly by fixture fixed installation. Can arranging multiple housing 11 on fixture, hammer handle 2 is installed with housing 11 one_to_one corresponding, and housing 11 is installed with sprue cup 12 one_to_one corresponding, to increase same batch output, it is to increase production efficiency.
In addition, after hammer handle 2 is arranged in housing 11, both central axes, to avoid hammer handle 2 to be partial to, reduce alloy hammer conforming product rate.
S4, sprue cup 12 is removably mounted on housing 11 top, and the first casting die 3 is set sprue cup 12 is fixed, avoid sprue cup 12 to deviate tup sand mold 10, cause can not pouring into a mould tup or tup distortion smoothly.
S5, in housing 11, pour into a mould the 2nd metallic substance by sprue cup 12.
The 2nd metallic substance in S6, housing 11 wraps up hammer handle 2 the 2nd end and condenses into tup 1, and tup 1 is integrally connected to form alloy hammer with hammer handle 2.
S7, dismantle the first casting die 3 and sprue cup 12, and alloy hammer is separated with housing 11, obtain alloy hammer finished product, as shown in Figure 9.
Adopting the alloy hammer that present embodiment is produced, tup 1 and hammer handle 2 are structure as a whole, and not easily pine is de-, security height, good reliability. And utilizing the manufacture method that present embodiment provides to produce alloy hammer, sand mold makes general inartful personnel and all can complete, and reduces cost of labor; Production method is simple and quick, greatly improves products production efficiency; Product yardstick deviation is little, it is to increase conforming product rate; Without the need to polishing, product appearance is good, highly polished. The method is applied widely, all can make by this method for different shape composite hammer head, only needs to change sand mold and makes mould.
The above; it is only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; any it is familiar with those skilled in the art in the technical scope that the present invention discloses; technical scheme and invention design thereof according to the present invention are equal to replacement or are changed, and all should be encompassed within protection scope of the present invention.
