Definitions
- the invention relates to a device for connecting a plurality of Tubes wound coils to a device for feeding and / or discharging Inert gas and a method of annealing tubes wound into coils using the device, wherein a plurality of coils in common annealed while being purged with inert gas.
- An essential field of application of the invention is the bright annealing of Copper pipes, as they are widely used in refrigeration. They serve to transport the refrigerant through the respective heat exchangers. Therefor it is imperative to flush the tubes with inert gas during annealing to the Contaminants of the pipe inner surface, the so-called occupancy to remove. A Remaining occupancy is only allowed within very narrow limits, otherwise the processes of Refrigeration would be sensitive affected.
- the invention is based on the object in the individual coils of the batches achieve uniform flushing performance.
- the matrix plug is attached to one of the annealing racks, usually the lowest Incandescent frame attached, and the Patrix connector forms the actual docking station inside the oven.
- the control of the Patrix connector and the Actuator is done from the outside, but on condition that the coils are in the docking station.
- the Actuator has a head with a continuously tapering circumference, in a recess of the Patrix connector, which is a complementary, steady having tapered circumference, is axially displaceable, wherein the head is a plurality of passage openings for receiving the pipe socket and having Side openings is provided, which from the through holes to the associated Lead circumferential surface and each a sliding, from the peripheral surface projecting clamping element, preferably in the form of a sphere.
- the Patrix plug When docking, the Patrix plug is inserted into the insertion hole of the matrix connector plugged in. Then, the actuator is moved, in that direction in which its circumference and that of the recess are tapered. The clamping elements come into contact with the circumference of the recess and be inward toward the through holes of the Actuator displaced by passing through the pipe socket. she engage the pipe socket and take it in their sealing position, whereby they push themselves into the pipe sockets. Any positional differences of Pipe sockets are automatically compensated. The actuator is held in its clamping position during annealing and then to Release the connection in the opposite direction.
- the head of the actuator may comprise an actuating rod which is passed centrally through the Patrix connector and around the Through openings of the head are preferably arranged in a circle.
- the Operating rod is sealed passed through the furnace wall and can be operate via a piston working machine arranged outside the furnace.
- the circumference of the head and the recess of the PatrixPlug may vary Rejuvenate the direction of the matrix connector.
- the pipe sockets are then in the Patrix connector and the actuator in the same direction in which also the insertion of the Patrix plug into the insertion opening of the matrix connector.
- the kinematics are so simple, as the Patrix plug not be held separately when moving the actuator got to. Manufacturing technology, however, this construction is complicated, apart that the pipe socket subject to wear inside the furnace need to be replaced.
- the pipe sockets sit here displaceable in the through holes of the matrix connector and are sealed by the actuator in the Through openings of the Patrix connector pulled in.
- the pipe sockets can So be replaced as soon as the Glühgestelle have left the oven.
- it is ensured by a corresponding lock that the Pipe socket when releasing the plug connection with the Patrix plug be pulled out.
- Conceivable are constructions in which the head of the actuating element and the associated recess of PatrixStecker a polygonal cross-section have and taper in a pyramid shape. This offers the advantage that the The angular position of the actuator is automatically fixed relative to the Patrix connector is. In terms of manufacturing technology, however, one is simpler from this point of view also preferred construction in which the head of the actuating element and the Recess of the Patrix connector frustoconical peripheral surfaces have and rotatably connected to each other.
- the invention further relates to a device for connecting a A plurality of coils wound from tubes to a device for supply and / or Discharge of inert gas and a process for annealing pipes that become coils are wound using the device wherein a plurality of coils annealed together and rinsed with inert gas.
- the invention is based on the knowledge that the previous different Rinsing performance of the individual coils can only be due to the fact that the individual coils are charged with different amounts of purge gas. Because the parallel supply conditions are uniform and also the Flow resistance of the individual coils are not significantly different from each other differences in quantity are due to the fact that unavoidable leakage losses are different.
- the invention ensures that each coil is rinsed separately and that different leakage can be compensated.
- that can emerging inert gas monitored for its content of impurities so that there is a possibility to customize the individual coils with the supply each adapted protective gas throughput.
- there is the Possibility in addition to the protective gas flow rate, the purge time and the Coil temperature control. Not only the content of impurities can the Control, but also their composition, for example, their carbon content.
- the invention also achieves a significant additional advantage. So far The contaminated inert gas was introduced into the furnace, making it to a Pollution of the oven interior and cold coil surfaces came. These Disadvantages omitted because the contaminated shielding gas derived directly from the coil becomes.
- To carry out the method according to the invention includes the "docking" of Coils to the separate inert gas lines, namely at the inlet and outlet ends. This Process step can be done with minimal effort, namely with a single Handling be performed with the device according to the invention.
- Figure 1 shows a matrix connector 1 for attachment to the lowest annealing of a Coil stacks and a Patrix plug 2, which at the docking station in one Insertion opening 3 of the matrix connector has been introduced.
- the insertion opening 3 has a conical peripheral surface 4, while the Patrix plug 2 at its Socket with a complementary conical peripheral surface 5 is provided.
- means not shown are provided which facilitate the insertion of the Patrix connector 2 in the insertion opening 3 of the matrix connector 1 only in one or several, defined predetermined angular positions allowed.
- the matrix plug 1 has a plurality of through holes 6, which can be connected to the individual coils are and in which pipe socket 7 slidably disposed are.
- the pipe stubs 7 extend through a head 8 an actuating element 9 through and are sealing from this in through holes 10 of the Patrix connector. 2 into tense.
- the entry areas of the passage openings 10 are for this purpose, as shown, flared.
- the Through openings 10 are on separate inert gas lines connected.
- the actuating element 9 has an actuating rod 11 on, preferably integrally connected to the head 8 and is passed centrally through the Patrix connector 2. Whose Through openings 10 are distributed in a circle around the actuating rod 11 of the actuating element. 9
- the head 8 of the actuating element 9 also has Through openings 12, pass through the pipe socket 7. To enter when making the connector the pipe socket 7 in the through holes 12 of the To facilitate head 8, the through holes 12, as shown, flared at their entry ends.
- the head 8 of the actuating element 9 has a conical Peripheral surface 13 and operates in a recess 14 of the Patrix connector 2, wherein the recess 14 with a complementary conical peripheral surface 15 is provided.
