Abstract
The utility model provides a water-cooled forming device for compositely casting a double-metal hammer head, belonging to the field of casting and forming equipment. The water-cooled forming device consists of an upper sand mould box, a lower water-cooled crystallizing box and a middle product mould cavity, wherein the upper sand mould box is fixedly connected with the lower water-cooled crystallizing box by a plurality of screw bolts, and an upper sand mould cavity with the worse thermal conductivity is connected with a lower metal mould cavity with the higher thermal conductivity to form into the middle product mould cavity. The device is used for controlling the solidification speeds of cast products with different shapes and sizes in the middle product mould cavity by controlling the flow of the cooling water of the lower water-cooled crystallizing box, thereby leading two molten irons with different materials to be stably and metallurgically combined with each other, and guaranteeing the vivid mechanical properties of the two different materials of the hammer head, i.e. the high abrasion performance of the hammer head and the high tenacity of a hammer handle. The device is simple in operation, high in production efficiency, and good in product quality, meets the technical requirement of the double-metal composite-cast hammer head, and achieves the important aim for manufacturing the high-quality hammer head of a crusher by the double-metal composite cast technology.
Description
Technical field
A kind of bimetallic tup of the utility model composite casting water-cooled shaped device belongs to the casting apparatus field.
Background technology
The bimetallic tup is widely used in field disintegrating machines such as cement, mine, metallurgy, building materials, road and water conservancy, this bimetallic tup should have higher mechanical properties and hardness number, hammer handle has partly required toughness index preferably, otherwise, to cause tup premature wear, hammer handle fracture, and cause operating efficiency to descend.
At present, the material of the used tup of disintegrating machine is based on potassium steel, the super manganese steel of part is also arranged and forge middle-low alloy steel etc., these materials have high toughness, can bear the impact of self and material macro-energy, but in the process of broken material, the reason self of decreasing owing to Mo Li Mo also can wear away soon.Though the material of high rigidity is wear-resistant, it can not be used for making whole tup, and this is because it holds the double action of the huge kinetic energy of moment and tup position that can't stand that the hammer handle position is bigger, and fracture is fallen soon.Adopting bimetallic to make grinder hammerhead, is tup producers' research, and the direction of tackling key problem if can be with a kind of high tenacity (ak value 〉=18J/cm
2) material and the material of another kind of high-wearing feature (HRC 〉=55) combine, forming the single integral piece tup have two kinds of performances concurrently is more satisfactory scheme.With regard to this scheme, preferably use the molten iron of two kinds of unlike materials, divide priority to pour into casting mold and form whole tup.But, traditional technology all is the casting that adopts single sand mold or single metal mold to realize tup, because not with the corresponding shaped device of above-mentioned technological design, its consequence has: one, the molten iron of two kinds of materials mix formation easily in die cavity a kind of neither wear-resistant, not impact-resistant again new material, they are two years old, the time interval of two kinds of material cast is long slightly, will form in conjunction with bad defective, and tup and hammer handle are hit slightly and will rupture.Therefore, shortage can be used to make the shaped device of bimetal composite casting tup, has just become to realize to produce the key issue of preparation tup with double-metal composite casting process.
The utility model content
The purpose of this utility model provides a kind of bimetallic tup composite casting water-cooled shaped device, with the wearability and the impact resistance of further lifting grinder hammerhead, prolongs the service life of grinder hammerhead.
This water-cooled shaped device, form by top sand mould box, bottom water-cooled crystallization case and middle part goods die cavity, the cast gate of top sand mould box, dead head and overfall are communicated with top sand mold die cavity respectively, characteristics are that the tank wall of bottom water-cooled crystallization case is respectively equipped with cooling water intake, delivery port, lower metal type die cavity is arranged in the case, the top sand mould box is connected through bolted with bottom water-cooled crystallization case, and its top sand mold die cavity and lower metal type die cavity connect and compose and be middle part goods die cavity.
The moulding die cavity of the bimetal composite casting tup of the utility model device, be by the higher lower metal type die cavity of water-cooled cooling and the combination casting mold die cavity that the relatively poor top sand mold die cavity of heat conductivity is formed by connecting of being subjected to of heat conductivity, the outstanding advantage of this device is that the setting rate of hammer handle position foundry goods can be regulated according to cooling water flow, can obtain the setting rate that needs to cast product in the die cavity of difformity different size, obtain firm metallurgical binding with the molten iron of guaranteeing two kinds of unlike materials.Whole tup after the crystallization has been guaranteed the mechanical performance of distinctness of two kinds of materials of two parts, i.e. the high-wearing feature at tup position, the high tenacity of hammer handle part.It is simple to operation, production efficiency is high to adopt this device to implement the bimetal composite casting operation, and product quality is excellent.The utility model device has satisfied bimetal composite casting tup process requirements, has realized the important goal with double-metal composite casting process production high-quality grinder hammerhead,

The specific embodiment
Now further specify in conjunction with the accompanying drawings and how to utilize this device,
This water-cooled shaped device, form by top sand mould box, bottom water-cooled crystallization case and middle part goods die cavity, the cast gate 4 of top sand mould box 1, dead head 5 and overfall 6 are communicated with top sand mold die cavity 3s respectively, one side box wall lower end of bottom water-cooled crystallization case 2 is provided with cooling water intake 7, be provided with delivery port 8 in upper end with water inlet 7 relative side box walls, lower metal type die cavity 3x is arranged in the case, top sand mould box 1 and bottom water-cooled crystallization case 2 are fastenedly connected through bolt L, and its top sand mold die cavity 3s and lower metal type die cavity 3x connect and compose and be middle part goods die cavity 3.
The operating process of implementing the bimetal composite casting tup is as follows:
Carbon complex alloy molten iron and rich chromium cast iron molten iron during melting synchronously is ready in two medium-frequency induction furnaces earlier, and control its tapping temperature, earlier with middle carbon complex alloy molten iron process cast gate 4, enter in the lower metal type die cavity 3x, when treating that spout hole 6 has molten iron to overflow, just stop cast, to be ready to the rich chromium cast iron molten iron more through dead head 5, enter in the sand mold die cavity 3s of top with middle carbon complex alloy molten iron also and combine at dissolved state, at this moment, in the water cooling case of bottom, cooling water enters bottom water-cooled crystallization case 2 from tank wall lower end water inlet 7, flow out from upper end delivery port 8 after the heat exchange, keep cooling water to circulate as required, to reach the purpose of molten iron in the cooling lower metal type die cavity 3x.Because the effect of metal mold cavity cooling gradient, transition zone can form a kind of new metallurgical adhesive by very fast solidification and crystallization, two kinds of materials with different properties are linked together, form bimetallic composite hammer head goods Z as shown in Figure 2, its tup part Za is made up of rich chromium cast iron, hammer handle part Zc is made up of middle carbon complex alloy, and transition zone Zb is made up of the mixture of two kinds of materials.Tup goods behind this coagulation forming after the polishing moulding, through high-temperature process, are bimetallic composite hammer head product.
