The heating copper ring is fixed on the outer circumferential surface of a steel ring when being used, the dismounting of the heating copper ring during the dismounting of hard alloy and the steel ring is avoided, the resistance increase of the heating copper ring is effectively prevented, good electric conductivity is ensured, the heat transfer performance of synthesis equipment is improved, simultaneously, the frequent dismounting and mounting are avoided, the labor, the materials and the time are also saved, and the production cost is greatly reduced.
Description
Technical field
The utility model belongs to the superhard material synthesis technical field, particularly a kind of heating copper ring.
Background technology
What at home, cubic apparatus synthesis press diamond synthesis mainly adopted is static pressure catalyst method.Static pressure catalyst method is meant under the thermodynamically stable condition of diamond, the method of diamond synthesis under the condition of constant superhigh-temperature and-pressure and catalyst participation, it promptly is raw material with graphite, do catalyst with transition metal or alloy, produce constant high pressure with hydraulic press, produce continuous high temperature with direct current or alternating current, make graphite be converted into adamantine process.Graphite becomes adamantine conversion condition and is generally 5 ~ 7Gpa and 1300 ~ 1700 ℃.
Because the hot conditions that the anti-high pressure member of cubic apparatus synthesis press is difficult to bear diamond film, so must be in the inner heating of high pressure chest, the easiest method is to adopt electrical heating, makes big electric current produce Joule heat by the heater in the high pressure chest, provides temperature conditions for graphite is converted into diamond.
Electrical heating is to introduce electric current from the external world, be connected on the steel loop by transformer, carbide alloy (top hammer) is fixed in the steel loop, and heated synthetic piece just is placed between two carbide alloy (top hammer), when heating, synthetic piece and two carbide alloy end faces compress and electric current are connected.Transformer mainly is to realize by connecting the copper pigtail line on both exits with being connected of steel loop.The exit of steel loop is meant the heating copper ring that is fixed on the steel loop bottom, and as shown in Figure 1, the heating copper ring comprises ring-type electric conductor 1, is provided with terminals 2 on ring-type electric conductor 1, is respectively equipped with axial screw 3 and wiring screw 4 on ring-type electric conductor 1 and terminals 2.Internal diameter, the external diameter that the internal diameter of heating copper ring equals steel loop bottom equals the external diameter of steel loop bottom.During use, the axial screw 3 of heating copper ring utilizes bolt to install with the corresponding connecting hole of offering 6 in steel loop shown in Figure 25 bottom surfaces to be one, and terminals 2 are electrically connected with copper pigtail line and transformer.
Because carbide alloy (top hammer) tends to need timely replacing after the damage because of factors such as quality problems own, human factor, equipment breakdown and service life cause damage in building-up process.Interference fit is fitted in carbide alloy (top is hammered into shape) and steel loop together, after carbide alloy (top hammer) is damaged, needs together from synthesis press dismounting, replacing.The heating copper ring is positioned at the bottom of steel loop, because itself matter is soft, the back easy deformation of exerting pressure, and damage axial screw 3 is so must dismantle the heating copper ring during compacting dismounting from the steel loop bottom.Heating copper ring dismounting frequently causes being connected and fixed loosening easily, thereby causes that resistance is excessive, reduces electric conductivity, and not only waste of manpower but also lose time of frequent dismounting.
The utility model content
The purpose of this utility model is at above-mentioned deficiency, and a kind of heating copper ring that can effectively avoid frequent dismounting and good conductivity is provided.
For achieving the above object, the technical solution of the utility model is: a kind of heating copper ring, comprise the circular arc electric conductor, and circular arc electric conductor two ends are extended with terminals, and the circular arc electric conductor is provided with radially connecting hole.
Described terminals be arranged in parallel, and terminals are provided with wiring hole.
Described radially connecting hole and wiring hole are screwed hole.
In the use, the utility model and steel loop are used, and offer circumferential groove on the outer peripheral face of steel loop bottom, and the circumferential groove bottom is provided with and the corresponding fixing hole of connecting hole radially; Utilize the soft characteristic of circular arc conduction physique, it in the circumferential groove of steel loop, is guaranteed that radially connecting hole is corresponding one by one with fixing hole, then by the bolt connection that is fixed; Place the copper pigtail line between the terminals that be arranged in parallel, by being arranged in the bolting copper pigtail line in the wiring hole, the realization transformer is electrically connected with steel loop.
Compared with prior art, the utility model has the advantages that:
1, is extended with the terminals that be arranged in parallel at circular arc electric conductor two ends, the circular arc electric conductor is provided with radially connecting hole, terminals are provided with wiring hole, the utility model is fixed on the outer circumference surface of steel loop during use, avoided dismounting heating copper ring when dismounting carbide alloy and steel loop, effectively prevent to heat copper ring resistance and become big, guarantee that electric conductivity is good, can improve the heat transfer property of synthesis device; Simultaneously, avoid frequent dismounting, both saved human and material resources, saved time again, greatly reduced production cost.
2, radially connecting hole and wiring hole are screwed hole, are convenient to dismounting, and be easy to use.

The specific embodiment
Heating copper ring as shown in Figure 3 and Figure 4, it comprises circular arc electric conductor 7, the two ends of circular arc electric conductor 7 are extended with the terminals 8 that be arranged in parallel, on circular arc electric conductor 7, be provided with radially connecting hole 9, two terminals 8 are provided with corresponding wiring hole 10, radially connecting hole 9 is screwed hole with wiring hole 10, is convenient to dismounting and wiring.
Circular arc electric conductor 7 can be formed in one with terminals 8, all adopts copper material, conducts electricity very well.
The utility model is used with as shown in Figure 5 steel loop 5, offers circumferential groove 11 on the steel loop 5 bottom outer peripheral faces, and circumferential groove 11 bottoms are provided with the fixing hole 12 corresponding with connecting hole radially 9.Utilize the soft characteristic of circular arc electric conductor 7 matter, it in the circumferential groove 11 of steel loop, is guaranteed that radially connecting hole 9 is corresponding one by one with fixing hole 12, then by the bolt connection that is fixed.Place the copper pigtail line between the terminals 8 that be arranged in parallel, by being arranged in the bolting copper pigtail line in the wiring hole 10, the realization transformer is electrically connected with steel loop 5.
