Abstract
The utility model discloses an electric heating wire with a tubular cold lead, which is suitable for various electric heating elements and devices, such as electric heating tubes, electric furnaces, etc. The electric heating wire is composed of an electric heating wire (1) and a tubular cold lead (2) jointed by pressing. The other end of the tubular cold lead of the electric heating wire can be pressed with a transitional conducting wire. The outside diameter of the tubular cold lead can also be processed with threads for connection with other elements. The electric heating wire with the tubular cold lead has the advantages of easy processing and low cost. The cold lead made of general copper and aluminum materials has electrical conductivity and mechanical properties both meeting operating requirements.
Description
The invention relates to heating alloy, particularly the heating wire two ends has the invention of the heating alloy of crimping tubulose eduction rod.
Existing heating alloy is being assembled into various electric heating elements when using, heating wire and eduction rod be connected with the groove milling cold-press method.Mill out a notch on eduction rod, groove width is a bit larger tham the heating wire diameter, will be inserted in the groove connection of colding pressing under momentum effect after the stretching doubling in heating wire end.Its shortcoming is that the manufacturing of groove milling eduction rod is comparatively complicated, and cost is higher.The boring welding is to bore a centre bore at the eduction rod end face, inserts heating wire, welds on the preformed hole of side, and its shortcoming is that the eduction rod manufacturing is comparatively complicated, and cost is higher, and welding operation is had relatively high expectations.
Task of the present invention is that a kind of heating wire that improves the eduction rod connecting mode will be provided, and is made up of heating wire and tubulose eduction rod.Particularly the heating wire eduction rod is the crimping tubular type, and the heating wire end therewith the connection of eduction rod adopt the connection method of colding pressing commonly used among the electrician, constitute firm firm connection, and have advantages such as operation is simple.
Task of the present invention is finished as follows, stretching and insert in the pipe of eduction rod [2] heating wire [1] termination portion, or insert in the pipe of eduction rod [2] after the stretching doubling of heating wire [1] termination portion, eduction rod [2] to this position radially imposes certain pressure, make eduction rod [2] produce radial deformation, thereby make solid and reliable being connected and constituting the present invention of eduction rod [2] and heating wire [1] termination formation.
Above-mentioned embodiment is done further to improve, thereby constitute another embodiment of the present invention.Its method is on the eduction rod [2] of heating wire [1] termination crimping, as the worker screw thread [3] is arranged on the external diameter away from the other end of the eduction rod [2] of heating wire [1] termination.So that adopting with external wire, the heating wire element is threaded.
Embodiment 3 is that the other end at the eduction rod [2] of heating wire [1] termination crimping inserts a transition lead [4], and this section eduction rod radially imposed certain pressure, make eduction rod [2] produce radial deformation, thereby make eduction rod [2] constitute solid and reliable being connected with transition lead [4].
The compression bonding method of eduction rod among the present invention [2] and heating wire [1] and transition lead [4] can adopt electrician's pressing tongs commonly used in the electrical maintenance to carry out crimping, also can adopt the electromagnetic traction impulse force several different methods such as connection of being colded pressing in need crimping position to carry out the crimping connection.
Below in conjunction with accompanying drawing the present invention is described in further detail.
Fig. 1 is the longitudinal sectional drawing of embodiment of the present invention 1;
Fig. 2 is the longitudinal sectional drawing of embodiment of the present invention 2;
Fig. 3 is the longitudinal sectional drawing of embodiment of the present invention 3;
Fig. 4 is the cold pressing connection of heating wire in groove milling;
Fig. 5 is heating wire being welded to connect in preformed hole.
With reference to Fig. 1, the two ends of heating wire [1] is inserted eduction rod [2] respectively, applies pressure or the impulse force connection of colding pressing with a certain size along the radial direction of eduction rod [2], carries out crimping etc. as adopting electrician's pressing tongs.Make the insertion position of heating wire [1] termination and the place of being squeezed of eduction rod [2] produce radially deformation, go up as eduction rod [2] and form load mould.Make heating wire [1] constitute solid and reliable being connected with eduction rod [2].
With reference to Fig. 2, and be processed with screw thread [3] on the external diameter of the other end of the eduction rod [2] of heating wire [1] crimping, thereby constitute another embodiment of the present invention.
With reference to Fig. 3, insert a transition lead [4] with the other end of the eduction rod [2] of heating wire [1] crimping, impose a certain size pressure or the impulse force connection of colding pressing along the radial direction of eduction rod [2], carry out crimping etc. as adopting electrician's pressing tongs.Thereby constitute embodiment of the present invention 3.
The heating wire that has the tubulose eduction rod can be used in multiple electric heating such as electrothermal tube, electric furnace unit, the device.Particularly on daily electric furnace was made, the heating wire that uses termination of the present invention to have the tubulose eduction rod substituted original common heating wire, has thoroughly solved electric furnace heating wire two ends and has been easy to cause the shortcoming of burning the accident that opens circuit, and has prolonged the useful life of electric furnace.The present invention processes simply, and cost is low.Material as eduction rod is copper commonly used, aluminium etc., and its electric conductivity and mechanical performance all can satisfy instructions for use.
Claims (3)
1, a kind of termination has the heating wire of tubulose eduction rod, is made up of heating wire [1] and tubulose eduction rod [2], it is characterized in that the two ends crimping that tubulose eduction rod [2] is enclosed within heating wire [1] forms.
2, heating wire according to claim 1, it is characterized in that at tubulose eduction rod [2] but other end crimping one transition lead [4].
3, heating wire according to claim 1 is characterized in that the external diameter of tubulose eduction rod [2] can be threaded [3].
