Abstract
The utility model discloses a shrinking pipe connector which comprises a frame, and a first contracted pipe mould and a second contracted pipe mould installed on the frame. The first contracted pipe mould and the second contracted pipe mould are arranged on the frame at an interval. The first contracted pipe mould comprises a first mould jacket and a first contracted pipe die orifice fixedly installed inside the first mould jacket. The second contracted pipe mould comprises a second mould jacket and a second contracted pipe die orifice fixedly installed inside the second mould jacket. The first and second contracted pipe die orifices are coaxially arranged. The caliber of the first contracted pipe die orifice is greater than that of the second contracted pipe die orifice. According to the pipe connector, two metal pipes can be compressed and bonded compactly by secondary pipe contraction, and the surfaces of the metal pipes are prevented from being strained.
Description
Technical field
The utility model relates to a kind of pipe connecting device, refers to that especially a kind of draw technology of utilizing is with the reducer coupling device of two metal tubes docking.
Background technology
Taking at present is to be that the metal tube of circular two various outer diameters docks with the cross section, to satisfy a fixed load.The mode of its adapter mainly contains welding or reducer coupling.The limitation of welding is larger, if the caliber gap of two metal tubes is larger, needs so port is processed and could be welded.And present reducer coupling mainly is that to utilize the disposable draw of pipe-reduction mold to compress bonding, exists like this blank area to connect insecure, two metal tube calibers and is prone to the problem that metal tube surface is pulled when differing larger, thereby affects its use.
The utility model content
Technical problem to be solved in the utility model is: a kind of reducer coupling device is provided, and this pipe connecting device utilizes the secondary draw two metal tubes can be compressed bonding firmly, and can guarantee that metal tube surface is not pulled.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of reducer coupling device, comprise frame, be installed on the first pipe-reduction mold and the second pipe-reduction mold on the frame, described the first pipe-reduction mold and the second pipe-reduction mold interval are arranged on the frame, described the first pipe-reduction mold comprises the first die coat and is fixedly installed in the first interior draw die orifice of the first die coat, described the second pipe-reduction mold comprises the second die coat and is fixedly installed in the second interior draw die orifice of the second die coat, described the first draw die orifice and the coaxial setting of the second draw die orifice, the bore of described the first draw die orifice is greater than the bore of the second draw die orifice.
As a kind of preferred scheme, described the first draw die orifice and the second draw die orifice are wolfram steel and make.
As a kind of preferred scheme, described the second pipe-reduction mold is installed on the frame by axial-adjustment unit.
As a kind of preferred scheme, described axial-adjustment unit comprises the fixedly swivel nut that is fixedly installed on the frame, and described fixedly swivel nut is provided with internal thread, and described the second die coat is provided with external screw thread, and described the second die coat is threaded with fixing swivel nut.
After having adopted technique scheme, effect of the present utility model is: because this pipe connecting device comprises the first pipe-reduction mold and the second pipe-reduction mold, therefore, the joint of two metal tubes is through the first for the first time reducer coupling of the first draw die orifice, can control the allowance of metallic pipe coupling, avoid the excessive metal surface of causing of the disposable undergauge of metallic pipe coupling to pull, also avoid a undergauge to cause connection not firm, and during again through the second draw die orifice, the allowance of the joint of two metal tubes is finished, thereby the joint of two metal tubes is more firm.
Be installed on the frame by axial-adjustment unit owing to the second pipe-reduction mold again, therefore, can axially adjust the position of the second pipe-reduction mold, like this, distance between the first pipe-reduction mold and the second pipe-reduction mold is with regard to capable of regulating, so, and under the constant prerequisite of two metal tube forward travel distances, just mean the joint length that to adjust as required undergauge, satisfy the different demands of product.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structure cutaway view of the utility model embodiment;
In the accompanying drawing: 1. frame; 2. the first pipe-reduction mold; 21. the first die coat; 22. the first draw die orifice; 3. the second pipe-reduction mold; 31. the second die coat; 32. the second draw die orifice; 4. fixing swivel nut.
The specific embodiment
Below by specific embodiment the utility model is described in further detail.
As shown in Figure 1, a kind of reducer coupling device, comprise frame 1, be installed on the first pipe-reduction mold 2 and the second pipe-reduction mold 3 on the frame 1, described the first pipe-reduction mold 2 and the second pipe-reduction mold 3 intervals are arranged on the frame 1, described the first pipe-reduction mold 2 comprises the first die coat 21 and the first draw die orifice 22 that is fixedly installed in the first die coat 21, described the second pipe-reduction mold 3 comprises the second die coat 31 and the second draw die orifice 32 that is fixedly installed in the second die coat 31, described the first draw die orifice 22 and the 32 coaxial settings of the second draw die orifice, the bore of described the first draw die orifice 22 is greater than the bore of the second draw die orifice 32.
Described the first draw die orifice 22 and the second draw die orifice 32 are wolfram steel and make.Described the first 22 one-tenth of draw die orifices are horn-like, and the second draw die orifice 32 then has a projection to the center position extension, utilizes this projection to add compressed pipe to front and back two metal tubes, guarantees its adhesive fastness.
Described the second pipe-reduction mold 3 is installed on the frame 1 by axial-adjustment unit.Described axial-adjustment unit comprises the fixedly swivel nut 4 that is fixedly installed on the frame 1, and described fixedly swivel nut 4 is provided with internal thread, and described the second die coat 31 is provided with external screw thread, and described the second die coat 31 is threaded with fixing swivel nut 4.Rotate the second die coat 31, can move axially, thereby adjust spacing between the second pipe-reduction mold 3 and the first pipe-reduction mold 2.
Operation principle of the present utility model is: at first, the metal tube of little external diameter is inserted from the first pipe-reduction mold 2, until the end of the metal tube of little external diameter is in outside the first pipe-reduction mold 2, the metal tube of large external diameter is enclosed within on the end of metal tube of little external diameter, and move forward simultaneously, the metal tube of large external diameter is in the first preshrunk controlled working surplus of the first pipe-reduction mold 2, the metal tube of its little external diameter enters into the second pipe-reduction mold 3 further reducer couplings with the joint of the metal tube of large external diameter, like this, will finish remaining allowance.Then the metal tube integral body after taking over withdraws from backward.
By in the above-mentioned course of work as can be known, the distance that two metal tubes are advanced forward is certain, adjust the spacing between the second pipe-reduction mold 3 and the first pipe-reduction mold 2, namely adjust for the second time duration of undergauge, thereby can make the joint length of two metal tubes be fit to product and customer requirement.
