Description
Technical field
The present invention relates to a kind of metal tube plastic joining field, especially a kind of crimping cable transition joint connecting tube
Electromagnetic pulse forming device and manufacturing process.
Background technique
The basic principle of electromagnetic pulse forming is to process pipe fitting, general circuit work using the electromagnetic force of high-intensity magnetic field generation
Make process are as follows: it first passes through charge circuit and charges to impulse capacitor group, capacitor energy storage is discharged after reaching predicted value,
At this moment fast-changing electric current will be flowed through in form-wound coil, will form transient magnetic field in space, in the metal tube close to coil
Interior generation vortex, thus metal tube can generate deformation under the action of electromagnetic force.
When carrying out the connection of pipe fitting using electromagnetic pulse forming technology, after making outer tube radial direction compressive deformation
It is pressed in inner tube to obtain connection effect.But if discharge energy is enough, the high quick deformation meeting of electromagnetic force bring is so that two
The connection on molecular level is obtained between root canal part, reaches the connection status similar to Solid-phase welding.
Currently, the method for use is using hydraulic tongs by conductor connecting tube pressure between in the cable during connector production
It is connected on cable core, as shown in figure 8, choosing in conductor connecting tube by four positions of two close end and center, uses six sides
Shape punch die is compressed.The crimping effect that obtains in this way is simultaneously bad, and the contact resistance for crimping finished product can be made excessive, and if
The connection effect similar to welding is obtained using electromagnetic pulse forming technology, then can improve this case.
It is all described in patent CN105965184A, CN107283041A and CN101905375A a kind of using line solenoid
Circle sum aggregate chinaware is used cooperatively the system of processing for carrying out weld-end fittings, but coil sum aggregate chinaware used in these patents is all whole
Body formula, it will appear be difficult to the case where taking out workpiece after processing is completed in the actual processing process, for example pipe fitting extends length
It spends very long or pipe fitting extended spot diameter and is greater than processing coil internal diameter.
A kind of processing coil system stacked by single-turn circular coil and an inductance loop is described in patent EP1024912R1
System, for being processed to cable connector.Two pieces of coils in the invention can open certain angle, and also include one
Convenient for being placed and taken out the spring system of cable connector, but since only one processes hole, it is only used for connecing cable termination
The processing of head, and it is unable to satisfy the requirement to cable intermediate joint processing.
A kind of coil system for carrying out weld-end fittings using electromagnetic pulse forming technology is described in patent CN106425191A,
In view of for convenience of after processing is completed taking out test specimen in the patent, a solenoid coil is cut along the face of mistake its axis
Into two, two parts coil can be opened in this way and is put into, takes out workpiece.But due to coil turn is more, between every circle
Spacing is small, and process can also make coil be deformed, and by each circle, fully corresponding splicing is in practical applications
Highly difficult.And since in process, the junction of every circle can all flow through the high current of hundred kilo-ampere grades, once it contacts
Undesirable part is easy for there is a phenomenon where striking sparks, and to equipment and operator, there are security risks, therefore this method is not
It is practical.
When carrying out the connection of cable intermediate joint using electromagnetic pulse forming technology, since this is in order to longer by two
Cable connection get up and the process that carries out, therefore can all there be the outwardly extending part of very long cable at connector both ends；And by
It can generally be enclosed with very thick insulating layer and shielded layer outside in cable core, therefore in addition to the core part peeled off for processing
Outside, the diameter of cable intermediate joint outwardly extending portion is much larger than the aperture of machining area, and the coil of practical application allows for
It conveniently and effectively splits and assembles, so as to being placed and taken out for workpiece.
Simultaneously as the production of cable intermediate joint is to be crimped on the cable core at both ends by a conductor connecting tube
Together, therefore to improve processing efficiency, the position for actually needing to crimp simultaneously has at two, this is also one in need of consideration and asks
Topic.
