Abstract
The utility model discloses a hot forging mould comprising a die core and a die sleeve, wherein the die sleeve is horizontally sleeved on the die core, a layer of lubricating film is clamped between the die core and the die sleeve, and both ends of the die core are leveled with both ends of the die sleeve. By manufacturing a module with an integral structure into a split structure of mutually and horizontally nesting the die sleeve and the die core, the high thermal-cracking resistance, the high thermal-fatigue resistance and the high high-temperature abrasion resistance of the die sleeve positioned at the outer side are retained, the die sleeve is not easy to form cracks when being chilled and heated, and the formed cracks are not easy to expand; and moreover, the weld bonding of liquid metal and the chemical erosion and damage can be effectively resisted, and the failure of the mould is avoided. The die core positioned in the die sleeve has high thermal-softening resistance and higher impact resistance, the integral strength and the pressure resistance of the module are ensured, and the service life of the module is enhanced. The module with the split structure has low processing cost and maintenance cost and good use performance and is especially suitable for being used in a hot forging and pressing mould.
Description
Technical field
The utility model relates to a kind of hot forged mould that uses in the forging and pressing process.
Background technology
The be full of cracks damage takes place heat fatigue and thermal wear is the two big main causes that hot-work die lost efficacy.Forge die as one of hot-work die all adopts integral module at present on market, integral module is simple in structure, easy to use, processing cost is lower, but along with technological progress with to forging and pressing the raising of range request, the use shortcoming of integral module also comes out more and more.As the common integral module of making by the 3Cr2W8V steel, its shape mostly is the cubic bodily form, Stability Analysis of Structures, easy to use, but because 3Cr2W8V steel thermal fatigue and toughness are relatively poor, integrally-built module compression when forging and pressing is concentrated relatively, very easily cracks, along with the expansion of crackle in integral module, to make integral module cracking even damage, have a strong impact on the normal use of module; The integral module that and for example common H13 steel is made, because H13 steel red hardness is poor, easy to wear, though can effectively improve the intensity and the toughness of module whole by adding various alloying components, but integral module needs all to change after wearing and tearing, not only cause energy waste, also can increase production cost, influence is produced and is carried out smoothly.How to overcome the generation of this situation,, reach the purpose that improves and improve the mould serviceability, just become the problem that the utility model need solve by improving the overall structure of mould.
The utility model content
In view of above-mentioned deficiency of the prior art, the utility model aim to provide a kind of rational in infrastructure, processing is simple, can effectively improve the hot forged mould of mold hot fatigability and mar proof.
The utility model is achieved through the following technical solutions:
A kind of hot forged mould comprises core rod and die sleeve, and clamping has one deck lubricating film between described core rod and die sleeve, and the die sleeve level is enclosed within on the core rod, and two end faces of core rod are concordant with the die sleeve two ends.
Described die sleeve be shaped as rectangle or square.
Described core rod is an elliptical cylinder-shape.
The upper and lower surface that described elliptical cylinder-shape core rod contacts with die sleeve is respectively equipped with a supporting plane.
Be respectively equipped with a plane on described elliptical cylinder-shape core rod and the left and right surfaces that die sleeve contacts.
Described core rod is that a size is prismatic.
Described lubricating film is a polytetrafluoroethylplastic plastic, and the thickness of described lubricating film is 0.3～0.5mm.
A kind of hot forged mould described in the utility model, by integrally-built module making is become by the nested branch body structure of the mutual level of die sleeve and core rod, make the die sleeve that is positioned at the outside both keep high hot-cracking resistance, heat-resistant anti-fatigue drag and high temperature resistance wearing and tearing ability, when standing chilling and shock heating, be difficult for forming the difficult expansion of crackle of crackle and formation, be highly resistant to liquid metal weldbonding and chemical erosion damage again, avoid mould to lose efficacy.And since between core rod and die sleeve clamping one deck lubricating film, make that core rod and die sleeve can be because of the overheated adhesions of mould, the while is not convenient to the loading and unloading between core rod and the die sleeve yet.The core rod that is positioned at the die sleeve horizontal positioned then has high heat resistanceheat resistant softening power and higher impact resistance, guarantees module whole intensity and resistance to pressure, the service life of having improved module.Divide the module of body structure, processing cost and maintenance cost are low, and serviceability is good, is particularly suitable for using in forge hot pressing mold tool.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1 and Figure 2, a kind of hot forged mould described in the utility model comprises core rod 2 and die sleeve 1, and clamping has one deck lubricating film 3 between described core rod 2 and die sleeve 1, and described lubricating film is a polytetrafluoroethylplastic plastic, and the thickness of described lubricating film is 0.3～0.5mm.Die sleeve 1 be shaped as rectangle, die sleeve 1 adopts the gun barrel material to make, core rod 2 be shaped as elliptical cylinder-shape, die sleeve 1 level is enclosed within on the core rod 2, core rod 2 two ends end faces are concordant with die sleeve 1 end face, core rod 2 employing hot die steels are made.In the use, die sleeve 1 directly contacts with the forge hot casting die, 2 supporting roles of playing vertical direction of core rod, and die sleeve 1 and core rod 2 supporting uses not only improve and have guaranteed the mar proof and the thermal fatigue resistance of module, also greatly reduce the manufacturing cost of mould.
Certainly, die sleeve also can be square, and core rod also can be the cylinder of other shape, and as shown in Figure 3, core rod 6 is an elliptical cylinder-shape, and the upper and lower surface that elliptical cylinder-shape core rod 6 contacts with die sleeve 7 is respectively equipped with a supporting plane.As shown in Figure 4, core rod 8 still is an elliptical cylinder-shape, and just the left and right surfaces that contacts with die sleeve 9 of elliptical cylinder-shape core rod 8 is respectively equipped with a plane.As shown in Figure 5, core rod 4 is eight prismatic, and die sleeve 5 is a rectangle.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
