Abstract
The invention discloses a reducer coupling device comprising a rack as well as a first reducing pipe mold and a second reducing pipe mold which are arranged on the rack, wherein the first reducing pipe mold and the second reducing pipe mold are arranged on the rack at intervals; the first reducing pipe mold comprises a first mold outer sleeve and a first reducing pipe mold opening fixedly arranged in the first mold outer sleeve; the second reducing pipe mold comprises a second mold outer sleeve and a second reducing pipe mold opening fixedly arranged in the second mold outer sleeve; the first reducing pipe mold opening and the second reducing pipe mold opening are coaxially arranged; and the caliber of the first reducing pipe mold opening is greater than that of the second reducing pipe mold opening. The reducer coupling device can be used for firmly pressing and bonding two metallic pipes by virtue of twice pipe reducing, and ensuring that the surfaces of the metallic pipes are not stretched.
Description
Technical field
The present invention relates to a kind of pipe connecting device, be meant a kind of reducer coupling device that utilizes draw technology with the butt joint of two metal tubes especially.
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 bigger, if the caliber gap of two metal tubes is bigger, need handles and could weld port so.And present reducer coupling mainly is that to utilize the disposable draw of pipe-reduction mold to compress bonding, exists blank area to connect insecure, two metal tube calibers like this and is prone to the problem that pull on the metal tube surface when differing big, thereby influences its use.
Summary of the invention
Technical problem to be solved by this invention is: a kind of reducer coupling device is provided, and this pipe connecting device utilizes the secondary draw can two metal tubes be compressed bonding firmly, and can guarantee that the metal tube-surface is not pulled.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of reducer coupling device; Comprise frame, be installed on first pipe-reduction mold and second pipe-reduction mold on the frame; Said first pipe-reduction mold and the second pipe-reduction mold separation are on frame, and said first pipe-reduction mold comprises first die coat and first draw die orifice that is fixedly installed in first die coat, and said second pipe-reduction mold comprises second die coat and second draw die orifice that is fixedly installed in second die coat; Said first draw die orifice and the coaxial setting of second draw die orifice, the bore of said first draw die orifice is greater than the bore of second draw die orifice.
As a kind of preferred scheme, said first draw die orifice and second draw die orifice are wolfram steel and process.
As a kind of preferred scheme, said second pipe-reduction mold is installed on the frame through axial-adjustment unit.
As a kind of preferred scheme, said axial-adjustment unit comprises the fixedly swivel nut that is fixedly installed on the frame, and said fixedly swivel nut is provided with internal thread, and said second die coat is provided with external screw thread, and said second die coat is threaded with fixing swivel nut.
After having adopted technique scheme; Effect of the present invention is: because this pipe connecting device comprises first pipe-reduction mold and second pipe-reduction mold, therefore, the joint of two metal tubes is through the reducer coupling for the first time earlier of 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 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.
Because second pipe-reduction mold is installed on the frame through axial-adjustment unit, therefore, can axially adjust the position of second pipe-reduction mold again; Like this; Distance between first pipe-reduction mold and second pipe-reduction mold just can be adjusted, so, and under the constant prerequisite of two metal tube forward travel distances; Just mean the joint length that to adjust undergauge as required, satisfy the different demands of product.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structure cutaway view of the embodiment of the invention;
In the accompanying drawing: 1. frame; 2. first pipe-reduction mold; 21. first die coat; 22. first draw die orifice; 3. second pipe-reduction mold; 31. second die coat; 32. second draw die orifice; 4. fixing swivel nut.
The specific embodiment
Through specific embodiment the present invention is made further detailed description below.
As shown in Figure 1; A kind of reducer coupling device; Comprise frame 1, be installed on first pipe-reduction mold 2 and second pipe-reduction mold 3 on the frame 1; Said first pipe-reduction mold 2 and second pipe-reduction mold, 3 separation are on frame 1, and said first pipe-reduction mold 2 comprises first die coat 21 and first draw die orifice 22 that is fixedly installed in first die coat 21, and said second pipe-reduction mold 3 comprises second die coat 31 and second draw die orifice 32 that is fixedly installed in second die coat 31; Said first draw die orifice 22 and the 32 coaxial settings of second draw die orifice, the bore of said first draw die orifice 22 is greater than the bore of second draw die orifice 32.
Said first draw die orifice 22 and second draw die orifice 32 are wolfram steel and process.Said first 22 one-tenth of the draw die orifices are horn-like, and second draw die orifice 32 then has a convexity to the center position extension, and utilization should convexity can guarantee its adhesive fastness to the front and back two metal tubes pressurization draw.
Said second pipe-reduction mold 3 is installed on the frame 1 through axial-adjustment unit.Said axial-adjustment unit comprises the fixedly swivel nut 4 that is fixedly installed on the frame 1, and said fixedly swivel nut 4 is provided with internal thread, and said second die coat 31 is provided with external screw thread, and said second die coat 31 is threaded with fixing swivel nut 4.Rotate second die coat 31, can move axially, thereby adjust the spacing between second pipe-reduction mold 3 and first pipe-reduction mold 2.
Operation principle of the present invention is: at first; The metal tube of little external diameter is inserted from first pipe-reduction mold 2; End until the metal tube of little external diameter is in outside first pipe-reduction mold 2, the metal tube of big external diameter is enclosed within on the end of metal tube of little external diameter, and moves forward simultaneously; The metal tube of big external diameter is at the first preshrunk control allowance of first pipe-reduction mold 2; The metal tube of its little external diameter enters into second pipe-reduction mold, 3 further reducer couplings with the joint of the metal tube of big external diameter, like this, will accomplish remaining allowance.Metal tube integral body after taking over then withdraws from backward.
By knowing in the above-mentioned course of work; The distance that two metal tubes are advanced forward is certain; Adjust the spacing between second pipe-reduction mold 3 and first pipe-reduction mold 2, i.e. adjustment is the duration of undergauge for the second time, thereby can make the joint length of two metal tubes be fit to product and customer requirement.
