Abstract
The utility model relates to a contact type high-frequency welding device of a large-straight slit metal pipe. The device comprises a high-frequency welding power supply and an impedor, and is characterized in that: a contact head is mounted on the two poles of the high-frequency welding power supply respectively; a mounting hole is formed at a mounting end of the contact head; and a contact plate with an outer surface protruding downwards is welded at the lower part of the contact end of the contact head. The device provided by the utility model has scientific and reasonable structure design and adopts a contact type high-frequency welding mode; in a large-diameter metal pipe welding process, the welding requirements can be met with relatively low power; and the device has the outstanding advantages of low energy consumption, high efficiency and low cost.
Description
Technical field
The utility model relates to high-frequency welding equipment, particularly a kind of big vertical masonry joint metal tube contact high-frequency welding equipment.
Background technology
At present; The form of induction of high frequency weldering is adopted in the welding of vertical masonry joint metal tube usually; It produces induced-current through concentric locking collar in the coupling of the outside circular induction coil of metal tube in workpiece; Make the workpiece weld zone have a resistance heat and be in the mecystasis of fusing, externally the effect of pressure roller realizes the combination of metal down.The induction of high frequency weldering is fit to be applied to the less tubing of diameter more, and its temperature raises fast, and welding effect is good.But, when major diameter tubing is welded, because the diameter of induction coil is big, the outstanding problem that the welding process life period is long, power is high, power consumption is high.The existing contact ratio-frequency welding exists contact head easy to wear, needs frequent change, the problem that cost is high.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of power consumption little, and efficient is high, the big vertical masonry joint metal tube contact high-frequency welding equipment that cost is low.
The utility model solves its technical problem and realizes through following technical scheme:
A kind of big vertical masonry joint metal tube contact high-frequency welding equipment; Comprise ratio-frequency welding power supply, impedor; It is characterized in that: the two poles of the earth at the high-frequency welding power supply are separately installed with contact head; Installation end at this contact head is shaped on installing hole, is welded with the outstanding contact plate of an outer surface downwards in the contact jaw bottom of this contact head.
And, be shaped on water-cooling channel at the installation end of contact head.
Advantage of the utility model and beneficial effect are:
1. this high-frequency welding equipment, it is welded with contact plate through the contact jaw at contact head, after contact plate produces wearing and tearing; Can reinstall contact plate; Because contact head and contact plate all adopt the red copper material, thereby are implemented to the saving raw material, the purpose that reduces cost.
2. this high-frequency welding equipment is shaped on water-cooling channel at the installation end of contact head, is convenient in welding process butt contact and lowers the temperature, and guarantees that the stable of welding process carries out.
3. the utility model scientific structure design is reasonable, adopts the contact high-frequency welding manner, in to the major diameter metal tube welding process, adopts smaller power can satisfy welding requirements, and it is little to have energy consumption, and efficient is high, the outstanding advantage that cost is low.
Description of drawings
Fig. 1 is the operation principle sketch map of the utility model;
Fig. 2 is the structural representation of the contact head of the utility model.
The specific embodiment
Through specific embodiment the utility model is done further to detail below, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of big vertical masonry joint metal tube contact high-frequency welding equipment comprises ratio-frequency welding power supply (not shown), impedor 3, and coaxial metal tube 1 inside that is inserted into of impedor is provided with pressure roller 2 in the metal tube both sides.Its innovation part is: be separately installed with contact head 4 at the two poles of the earth of high-frequency welding power supply, be shaped on installing hole 6 at the installation end of this contact head, be welded with the outstanding contact plate 7 of an outer surface in the contact jaw bottom of this contact head downwards.Contact head and contact plate all adopt the red copper material to process.After contact plate produced wearing and tearing, welded and installed contact plate had again been avoided changing contact head and the waste of material that causes.Installation end at contact head is shaped on water-cooling channel 5.
Claims (2)
1. one kind big vertical masonry joint metal tube contact high-frequency welding equipment; Comprise ratio-frequency welding power supply, impedor; It is characterized in that: the two poles of the earth at the high-frequency welding power supply are separately installed with contact head; Installation end at this contact head is shaped on installing hole, is welded with the outstanding contact plate of an outer surface downwards in the contact jaw bottom of this contact head.
