Abstract
The invention relates to a tetrahedron press top hammer for a tetrahedron press, comprising top hammer bodies which are cylinders. Three inclined planes are arranged at one end of each of the top hammer bodies by taking a center line as the axes; the inclined angle between each of the three inclined planes and the center line of the top hammer body is 50-60 degrees; a section formed by the three inclined planes is provided with a concave spherical surface by taking the center line of the top hammer body as the axes; the concave spherical surface is intersected with the three inclined planes to form three edge lines; three small inclined planes which form inclined angles of 5-10 degrees are arranged at the positions lower than the three edge lines on the three inclined planes; and four top hammer bodies with the concave spherical surfaces are in abut joint by taking the centers of circles of the concave spherical surfaces as axes. The invention meets the requirements of the tetrahedron press on a synthetic cavity and takes working surfaces with the spherical surfaces, so that the temperature and the pressure of the synthetic cavity are more evenly distributed; and each spherical surface is provided with three edge lines and lacks one side compared with a square plane used by a cubic apparatus, which is beneficial to sealing the synthetic cavity.
Description
Technical field
The invention belongs to the synthetic field of super-pressure, relate in particular to a kind of tetrahedron press top hammer that is used for tetrahedral press.
Background technology
In the synthetic field of super-pressure, generally use synthetic of square at present, top hammer working face is a square-shaped planar, and the temperature and pressure in the synthetic chamber that forms like this distributes just even inadequately, and is unfavorable for the sealing in synthetic chamber.
Summary of the invention
The objective of the invention is to change the deficiency of prior art and provide a kind of temperature and pressure of synthetic chamber to be evenly distributed, high efficiency, the tetrahedron press top hammer of good airproof performance.
Technical scheme of the present invention is achieved in that and comprises top hammer body; Top hammer body is a cylinder; This top hammer body one end is that axis is provided with three inclined-planes with its center line; Three inclined-planes are 50 °-60 ° with the angle that pushes up hammer body center line; On the section of three inclined-planes formation, hammering the body center line into shape with the top is that axis is provided with concave spherical surface, and it is three edge lines that concave spherical surface and three inclined-planes intersect, and the position that on three inclined-planes, is lower than three edge lines is provided with three little inclined-planes that become 5 ° of-10 ° of angles with the inclined-plane.
Four top hammer bodies that have a concave spherical surface are formed centrally butt joint in the center of circle of concave spherical surface being.
Gap between the interface of described four top hammer bodies is 4mm-5mm, between the interface of four top hammer bodies, is provided with potted line.
Described top hammer body exterior is set with steel loop, and this steel loop one end is provided with three curve slopes that overlap with three little inclined-planes.
The described concave spherical surface that is arranged on the hammer body of top is 1/4th spheres.
The present invention has following advantage: the present invention answers the requirement of the involutory coelosis of tetrahedral press; Adopt the concave spherical surface working face; Make the temperature and pressure in synthetic chamber distribute more all with, each concave spherical surface has three sidelines, compares with the square plane that cubic apparatus is used; Few limit helps the sealing in synthetic chamber.
Description of drawings

Fig. 2 is the front view of top hammer body.
The specific embodiment
Like Fig. 1, shown in 2; The present invention includes top hammer body 1; Top hammer body 1 is cylinder; This top hammer body 1 one ends are that the angle that axis is provided with 2, three inclined-planes, three inclined-planes 2 and top hammer body 1 center line is 50 °-60 ° with its center line, are that axis is provided with concave spherical surface 3 with top hammer body 1 center line on the section that forms on three inclined-planes 2; It is three edge lines 4 that concave spherical surface 3 and three inclined-planes 2 intersect, and the position that on three inclined-planes 2, is lower than three edge lines 4 is provided with three little inclined-planes 5 with 2 one-tenth 5 °-10 ° of angles in inclined-plane.
Four top hammer bodies 1 that have a concave spherical surface 3 are formed centrally butt joint in the center of circle of concave spherical surface 3 being.
Gap between the interface of described four top hammer bodies 1 is 4mm-5mm, between the interface of four top hammer bodies 1, is provided with potted line.
Described top hammer body 1 outer cover is equipped with steel loop 6, and these steel loop 6 one ends are provided with three curve slopes 7 that overlap with three little inclined-planes 5.
The described concave spherical surface 3 that is arranged on the hammer body 1 of top is 1/4th spheres.
According to the principle that the centre of sphere of the circumsphere of positive tetrahedron overlaps with the body-centered of positive tetrahedron, a tetrahedral pairing sphere of face is 1/4th of a whole sphere, according to said method, is divided into four parts to whole sphere.Top hammer working face is the pairing concave spherical surfaces of above-mentioned 1/4th spheres, and four top hammer axis overlap with four high lines of positive tetrahedron respectively, and like this, the working face of four top hammers just forms a spherical cavity.Leave the gap of 4mm～5mm between the faying face of each top hammer, be used to form potted line.
Go out three inclined-planes about the cylinder axis circumference uniform distribution in a cylindrical end-grain cutting, inclined-plane and axis angle are 50 °～60 °, and on three inclined-planes, cutting out three is 5 °～10 ° inclined-plane with the inclined-plane angle.Dig out concave spherical surface at cylindrical section, be working face.Hammer outside, top is with the steel loop protection, and the inclined-plane that overlaps with top hammer ramp is also cut in the steel loop end, and steel loop adopts interference fits with the top hammer.
