A heating coil, the heating device further include having control mechanism, and the control mechanism includes temperature sensor, temperature control box,
The temperature sensor is mounted on the outside of beryllium copper pipe, and the temperature sensor is electrically connected with temperature control box.
As a further improvement of the above technical scheme, the feed device includes feed belt.
As a further improvement of the above technical scheme, the inner face of the beryllium copper pipe has plated inoxidzable coating.
As a further improvement of the above technical scheme, the heating coil has multiple, and multiple heating coils are equal
It is distributed on the outside of beryllium copper pipe evenly.
The beneficial effects of the utility model are: the utility model is by carrying out being processed into for seal wire using two layers of heat-shrink tube
Type, using the heat-shrink tube of the heat-shrink tube indirect heating internal layer of outer layer, so that the heat-shrink tube of internal layer melts and closely connect with core
Together, it is effectively protected using heat-shrink tube of the heat-shrink tube of outer layer to internal layer, not only makes the outer surface of internal layer heat-shrink tube
It is smooth, and under the sizing of outer layer heat-shrink tube, the size of internal layer heat-shrink tube is more stable.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.Obviously, described attached drawing is a part of the embodiment of the utility model, rather than complete
Portion's embodiment, those skilled in the art without creative efforts, can also be obtained according to these attached drawings it
His design scheme and attached drawing.
Fig. 1 is the device structure schematic diagram of the utility model.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection
It encloses.In addition, all connection/connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more preferably coupling structure.Each technology in the utility model creation
Feature, can be with combination of interactions under the premise of not conflicting conflict.
Referring to Fig.1, the utility model provides a kind of molding equipment of interventional therapy seal wire, includes heating device 1, institute
The front end for stating heating device 1 is equipped with feed device 2, and the rear end of the heating device 1 is equipped with cooling blower 3, institute's cooling wind
3 rear end of machine is equipped with discharging device 4；The heating device 1 includes beryllium copper pipe 11, and being covered over for the beryllium copper pipe 11 is multiple
Heating coil 12, the heating device 1 further include having control mechanism 13, and the control mechanism 13 includes temperature sensor, temperature
Case is controlled, the temperature sensor is mounted on the outside of beryllium copper pipe 11, and the temperature sensor is electrically connected with temperature control box.Processing when
It waits, using feed device and control mechanism, the molding of seal wire can be made to be automatically performed, substantially increase production efficiency.
It is further used as preferred embodiment, the feed device 2 includes feed belt.
It is further used as preferred embodiment, the inner face of the beryllium copper pipe 11 has plated inoxidzable coating.
