Abstract
The utility model discloses a top hammer of cubic press, relating to the technical field of super hard material equipment, comprising an installing part and a working part including a four-prism body. The top surface of the four-prism body is a square plane surface; the rate of the diameter of the connecting point of the installing part and the working part and the top surface of the four-prism body is less than 2.6. The top hammer of the cubic press is arranged on the cubic press. Compared with the prior art, the utility model mainly solves the problem of deflating the volume of the top hammer, enhancing the sintering quality and reinforcing the strength under the precondition of not reducing the dimension of the top surface and not lowering the whole bearing performance, therefore, the consumption of the top hammer of the cubic press in using is decreased.
Description
Technical field
The utility model relates to makes the superhard material apparatus technology, especially a kind of top hammer that is used on the cubic hinge press.
Background technology
China is the big producing country of diamond and cubic boron nitride superhard material, and the synthesis device of these superhard materials mainly is homemade cubic hinge press, as the SDP-6X16700 type cubic hydraulic press of Xianyang superhard material equipment Group Plc production.Top hammer on the press is a critical component of implementing pressurization when being used for the synthesizing superhard material, bears very big pressure (reaching 7.0GPa) and very high temperature (up to 800 ℃) at work, is the consumable accessory on the machine, consumes very big.The top hammer of this press is by installation portion and operate portions is compound constitutes, its installation portion is that cross section is circular cone, its operate portions is made of two different truncated rectangular pyramids bluk recombinations of gradient, its end face is a square-shaped planar, its installation portion is very big with the ratio of its end face length of side with the diameter of operate portions joint, even up to 3.3 times.On the cubic hinge press of superhard materials such as manufacturing diamond, make the requirement that the cubic hinge press cavity maximizes because its end face length of side must reach, therefore, the top of this structure is hammered its bottom body diameter into shape and has been reached 130 millimeters at present, height overall is at 95 millimeters, and also has the trend that continues expansion.The top of this structure hammer not only consumes a large amount of tungsten carbides and makes raw material, and large-sized like this Talide is difficult on manufacturing process that sintering is all even to be grilled thoroughly fully, therefore can cause strength of materials deficiency, and service life is short, and loss is excessive.
Summary of the invention
The cubic hinge press top hammer that the utility model provides, the subject matter that it solves is not reduce its end face size, do not reducing under the prerequisite of whole load performance, dwindles the volume of top hammer, improves top hammer intensity, thereby reduces to push up hammer consumption in use.
In order to address the above problem, the scheme that the utility model adopts is: according to the stressed needs of cubic hinge press top hammer, change top hammer structure, it is long-pending to dwindle the top hammer body, in use, adopt steel loop or steel bowl to be enclosed within outside the bottom of small size top hammer, in order to will push up in the mount pad that hammer into shape stressed be distributed to cubic hinge press.Described cubic hinge press top hammer is by installation portion and operate portions is compound constitutes, described installation portion is that cross section is circular cylinder or cone, described operate portions includes a truncated rectangular pyramids body, the end face of this truncated rectangular pyramids body is a square-shaped planar, and the diameter D of described installation portion and described operate portions joint and the ratio of the length of side a of described end face are less than 2.6; The diameter of described installation portion and operate portions joint, i.e. the diameter of the lowest part of installation portion and operate portions handing-over.
Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:
It is nearly 2/3 that this cubic hinge press top hammer volume ratio prior art has been dwindled, and on the one hand, reduced the consumption of Hardmetal materials greatly; On the other hand, guarantee employing tungsten carbide sintering process quality, thereby can improve nearly one times of service life.
Description of drawings
Fig. 1 is the front view of embodiment of the present utility model.
Fig. 2 is the vertical view of embodiment of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail:
As depicted in figs. 1 and 2, this cubic hinge press top hammer, its installation portion is up big and down small cone, its operate portions is a truncated rectangular pyramids body, the diameter of its installation portion and operate portions joint, i.e. the diameter of the lowest part of installation portion and operate portions handing-over is D; The end face of its operate portions is a square-shaped planar, and its length of side is a's; The overall height of cubic hinge press top hammer is H:
One of example is to be used for 12000 tons of top hammers on the cubic hinge press, its D/a=2; H/a=2, promptly end face length of side a is that the diameter D of 45 millimeters, installation portion and operate portions joint is that 90 millimeters, total height H are 90 millimeters.This top hammer compared with prior art adopts the carbide alloy manufacturing equally, and its volume only is 65% of a prior art, and the actual consumption of using the top to hammer into shape only is 30% of prior art.
Two of example is the top hammers that are used for 12000 tons of cubic hinge press on the hexahedron top press, its D/a=2; H/a=4/3, promptly end face is that the diameter D of 45 millimeters, installation portion and operate portions joint is that 90 millimeters, total height H are 60 millimeters for length of side a.This top hammer compared with prior art adopts the carbide alloy manufacturing equally, and its volume only is 34% of a prior art, and the consumption of actual use top hammer only is
25% of prior art.
Claims (3)
1, a kind of cubic hinge press pushes up hammer, the top hammer of this press is by installation portion and operate portions is compound constitutes, the cross section of described installation portion is circular, described operate portions includes a truncated rectangular pyramids body, the end face of this truncated rectangular pyramids body is a square-shaped planar, it is characterized in that: the diameter D of described installation portion and described operate portions joint and the ratio of the length of side a of described end face are less than 2.6.
