Abstract

The utility model discloses a novel built-in copper heating ring, which comprises a ring-shaped conductor, and the ring-shaped conductor is provided with axial connecting holes. The novel built-in copper heating ring has a simple structure, is convenient to mount, machine and produce, and can be firmly and reliably mounted; when in use, the novel built-in copper heating ring is not stressed in an annular groove of a steel ring, consequently, the copper heating ring can be effectively prevented from being dismounted when an anvil and the steel ring are dismounted, the resistance of the copper heating ring can be effectively prevented from being increased, and the electrical conductivity is good; and meanwhile, frequent dismounting and mounting can be avoided, consequently, manpower, material resources and time are saved, and the production cost is greatly reduced.

Description

A kind of novel built-in heating copper ring

Technical field

The utility model belongs to the superhard material synthesis technical field, particularly a kind of novel built-in 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 is raw material with graphite promptly under the condition of constant superhigh-temperature and-pressure and catalyst participation, does 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 through the heater in the high pressure chest, for graphite is converted into diamond temperature conditions is provided.

Electrical heating is to introduce electric current from the external world, is connected on the steel loop through transformer, and the top hammer is fixed in the steel loop, and heated synthetic piece just is placed between two top hammers, and when heating, synthetic piece is compressed by two top hammers and electric current is connected.Transformer mainly is to lean on both exits to connect the realization of copper pigtail line with being connected of steel loop; And the exit of steel loop is the heating copper ring that is fixed on the steel loop bottom; As shown in Figure 1; The heating copper ring comprises ring-type electric conductor 1, and internal diameter, the external diameter that the internal diameter of ring-type electric conductor 1 equals steel loop bottom equals the external diameter of steel loop bottom; On ring-type electric conductor 1, be provided with terminals 2, on ring-type electric conductor 1 and terminals 2, be respectively equipped with axial screw 3 and wiring screw 4.During use, the axial screw 3 of heating copper ring installs through bolt with the corresponding connecting hole of offering 6 in steel loop shown in Figure 25 bottom surfaces and is one, and terminals 2 are electrically connected with copper pigtail line and transformer.

Because the top hammer tends in building-up process because of factors such as quality problems own, human factor, equipment breakdown and service life cause damage, need after the damage in time to change.Because pushing up hammer is interference fit with steel loop, after pushing up the hammer damage, need the top to hammer into shape with steel loop from synthesis press dismounting, replacing.The heating copper ring is positioned at the bottom of steel loop, because itself matter is soft, adopts the compacting assembly and disassembly methods back heating copper ring easy deformation of exerting pressure, and damages axial screw 3 easily, so must dismantle the heating copper ring from the steel loop bottom during compacting dismounting, complex operation is wasted time and energy.The dismounting of heating copper ring frequently causes connecting fixing loosening easily, thereby causes that resistance is excessive, reduces electric conductivity.

The utility model content

The purpose of the utility model is to above-mentioned deficiency, and a kind of simple in structure, the novel built-in heating copper ring that can avoid frequent dismounting, good conductivity is provided.

For realizing above-mentioned purpose, the technical scheme of the utility model is: a kind of novel built-in heating copper ring, comprise the annular electric conductor, and the annular electric conductor is provided with axial connecting hole.

Said axial connecting hole is a screwed hole, and it is distributed on the annular electric conductor.

Compared with prior art, the utility model has the advantages that: the utility model comprises the annular electric conductor, and the annular electric conductor is provided with axial connecting hole, and is simple in structure, easy for installation, solid and reliable, is convenient to processing and manufacturing; During use, the utility model does not stress in the cannelure of steel loop, can effectively avoid dismounting heating copper ring when dismounting top hammer and steel loop, effectively prevents to heat copper ring resistance and becomes big, conducts electricity very well; Simultaneously, can avoid frequent dismounting, both practice thrift human and material resources, save time again, greatly reduce production cost.

The specific embodiment

Novel built-in heating copper ring as shown in Figure 3, it comprises annular electric conductor 7, and annular electric conductor 7 is provided with axial connecting hole 8, and axially connecting hole 8 is a screwed hole, and it is distributed on the annular electric conductor 7, is convenient to dismounting and wiring.Annular electric conductor 7 adopts copper material, conducts electricity very well.

When the utility model and steel loop 9 as shown in Figure 4 are used, offer the cannelure 11 that adapts with annular electric conductor 7 on steel loop 9 bottom surfaces, cannelure 11 bottoms are provided with the fixing hole 10 corresponding with axial connecting hole 8; Utilize the soft characteristic of annular electric conductor 7 matter, in its cannelure 11 of packing into, guarantee that axial connecting hole 8 is corresponding one by one with fixing hole 10, then through the bolt connection that is fixed; The copper pigtail line is through being arranged in the bolt in the axial connecting hole 8, and the realization transformer is electrically connected with steel loop 9.
