The specific embodiment
The invention provides a kind of copper pipe or copper Al pipe butt welding electrical heating pincers, be mainly applicable to the heating operation in copper pipe, copper Al pipe butt welding, it realizes principle can be with reference to accompanying drawing 1.
Shown in accompanying drawing 1, welding electrical heating clamps after switching on power, and temperature-control circuit (14) is connected electric heating body (3) power supply; Electric heating body (3) heat temperature raising after energising, heat heat conduction jaw (1) simultaneously, jaw temperature signal is fed back to temperature-control circuit (14) by temperature sensor in heat conduction jaw (1), in the time that heat conduction jaw (1) reaches preset temperature 550 and spends, temperature-control circuit (14) turn-offs electric heating body (3) power supply; When heat conduction jaw (1) temperature is down to 490 while spending, temperature-control circuit (14) is connected electric heating body (3) power supply again, continuing energising heats up, heat conduction jaw (1) is heated, be heated to 550 degree and turn-off again electric heating body (3) power supply.So iterative cycles, to maintain heat conduction jaw (1) temperature in the interval 490-550 degree of preset temperature.
Shown in accompanying drawing 2, electrical heating clamps mainly by heat conduction jaw (1), electric heating body (3), temperature control system, heat insulation structural (6,7,8), caliper support (10,19) and a few part of portable handle (13,15) form.
Electric heating body (3) is one an electric heating tube is wrapped in to inner casting pig, the power of the electric heating tube of its parcel is 220V, 600W, can be heated to temperature more than 550 degree by overall casting pig after energising, to meet the requirement of heating heat conduction jaw (1).Heat conduction jaw (1) is a stainless cast steel part, it is made into arc vice jaw according to conventional copper pipe specification, in the time of heating copper tube, can keep farthest reliable contact-making surface with heated pipe fitting, both promote firing rate, guarantee again heated pipe fitting surrounding homogeneous heating.Heat conduction jaw (1) positioned inside has temperature sensor in addition, its effect is to be that the signal of telecommunication passes back to temperature-control circuit (14) by the temperature inversion of heat conduction jaw (1), it is complete that temperature-control circuit (14) judges according to this signal whether heat conduction jaw (1) has heated, thereby whether decision turn-offs or the power supply of electric conduction calandria (3).
Between electric heating body (3) and heat conduction jaw (1), use 5 M3X6 stainless steel holding screws (2) to be twisted into reliably entirety, to guarantee high efficiencies of heat transfer between the two, reduce the temperature difference between the two.Electric heating body (3) below couples together with heat insulation structural (6,7,8) with 3 M3X6 stainless steel holding screws.
Heat insulation structural (6,7,8) be the thermal insulation space structure that a radiator-grid by porous (7), mesh minor flaps (6) and asbestos insulation material (8) form, because radiator-grid (7) directly contacts with the electric heating body (3) of high temperature, so must use resistant to elevated temperatures 304 materials, thickness is about 1.3mm, length reaches 75mm, and punching have a large amount of heat radiation apertures, to guarantee enough temp buffers.Radiator-grid (7) centre position is designed to hollow, and fills thermal insulation material, can effectively stop the heat of heat conduction jaw (1) directly to caliper support (10,19) radiation.At radiator-grid (7) and caliper support (10,19) fixed position, the asbestos insulation material (8) that 50mm is thick, heatproof 500 is spent has been installed, to completely cut off radiator-grid (7) to caliper support (10,19) heat conduction, asbestos insulation material (8) centre position is designed with electric wire by hole, can guarantee that the power line of temperature-control circuit (14) arrives the electric heating body (3) of front end through this hole.These two thermal insulation measures can reduce the temperature of caliper support (10,19) greatly, and protection workmen is not burned in the time of operation.
Mesh minor flaps (6) in heat insulation structural (6,7,8) is that thickness is 1.3mm for sealing dehiscing of radiator-grid (7), also using 304 stainless steels.It uses 4 M3X6 CARBURIZING FURNACE FOR STAINLESS FASTENERs (5) to be arranged on radiator-grid (7) side, to keep the inner thermal insulation material of radiator-grid (7) can not drop out.
Radiator-grid (7) is fixed on the mount pad of caliper support (10,19) across asbestos insulation material (8) by fixed screw (11) attaching nut (4) of 3 M3X20.Caliper support (10,19) uses the thick cold bundle steel plate of 2.0mm to make, to guarantee the bulk strength of electrical heating pincers.Caliper support (10,19) centre position is designed with a turning joint, the caliper support (10,19) of the left and right sides, after this turning joint is used fixed screw (9) to connect, can make heat conduction jaw (1) free-open-close.Turning joint place is also provided with the spring of remaining silent (21), and this spring can guarantee that heat conduction jaw (1) is kept closed when without external force, is conducive to constructor's one hand and controls electrical heating pincers, vacates another hand and carries out welding operation.The cabling of the cable buncher (20) that turning joint place is installed in can fixed caliper support (10,19), makes it not to be subject to the impact of joint motion, prevents that wire rod wearing and tearing from causing electric leakage accident.
Caliper support (10,19) below, is used the tapping screw (12) of 2 ST3.5X16 to be fixed on hand-held handle (13,15).Hand-held handle (13,15) is made for ABS plastic, and specification is diameter 45X185mm, and coated outside has flexible glue, to increase the fastness of gripping.Hand-held handle (13,15) appearance is designed with trade mark and patent is produced a mouthful signal language.Overall construction design becomes left and right closed type, and temperature-control circuit (14) is installed in hand-held handle (13,15).Temperature-control circuit (14), according to the temperature sensor signal in heat conduction jaw, is controlled the power supply of electric heating body (3), maintains in the temperature range 490-550 degree of design to control heat conduction jaw (1) temperature.
Two hand-held handles (13,15) terminal position is also designed with different assemblies, there is one to be designed with endways power switch (17), indicator lamp and power line (16), the contents such as the tip designs of another has a metallic data plate (18), title, power, voltage, date of manufacture and the manufacturer of sign product.
In order better to allow general technology person understand the present invention, below we simply describe the course of work of this welding electrical heating pincers:
1, by this welding electrical heating cramp joint energize, bi-colour LED redness lights, and represents that heat conduction jaw is just in heating process;
2, after several minutes, bi-colour LED is transformed into blueness, represents that heat conduction jaw has been heated to 490-550 degree temperature range;
3, according to soldered copper pipe or copper aluminum pipe specification, the suitable jaw of welding clamp is clamped on welded part;
After about 4, one minutes, welded part reaches welding temperature, welding rod can be positioned over to weld bond place, melts welding.
5, after having welded, remove welding clamp, powered-down, welding job completes.
Described above is only preferred embodiment of the present invention, and all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
