Description
Technical field
The present invention relates to field of machining, and in particular to a kind of drawing copper tubes device.
Background technology
Drawbench is the equipment that drawing is carried out to metal material.The diameter for making metal material by drawing changes, with
Reach required diametric requirements.It is drawn by sky, the various drawing modes such as trip head drawing and change mold can draw various different sizes
The bar and tubing of diameter.Since drawing processing does not cut embryo material, material is more saved, therefore gradually favored.
Drawing pipeline specific method is as follows：First, blank made of copper is squeezed to obtain copper extruding raw material pipe, is squeezed by this
After mother tube is cut to predetermined length, drawing processing more than a time or two passages based on mold and plug is carried out, and
It after obtaining the copper pipe of predetermined shape (outer diameter, internal diameter, wall thickness), cut off, the chamfer machining of end, washing, check ruler
The processes such as very little and appearance.
In the drawing processing for carrying out tubing, plug is placed in extruding raw material pipe so that and plug forms a collar extension with mold,
Tubing is pulled out from collar extension, is defined with the shape to tubing, is obtained internal diameter, the outer diameter tubing consistent with wall thickness.Due to plug
It needs to be fixed on pedestal, so that plug is in be relatively fixed state with mold, usual plug is fixed on by bar on pedestal；Adding
During work, bar is always in extruding raw material pipe, and bar is subjected to great pressure, and bar does not bend in order to prevent, then
Bar is unsuitable long, so that the limited length of extruding raw material pipe, therefore, the clamping times of extruding raw material pipe increase, Wu Fashi
Existing Continuous maching, processing efficiency are relatively low.
Invention content
The purpose of the present invention is to provide a kind of drawing copper tubes devices, can not process longer extruding raw material pipe with solution and lead
The problem of processing efficiency of cause is relatively low.
In order to achieve the above objectives, base case of the invention is as follows：
Drawing copper tubes device includes pedestal, mold, plug, haulage gear and driving motor, and mold is fixed on pedestal, core
Stick cooperatively forms collar extension with mold, and pedestal is equipped with sliding rail, and haulage gear is slidably connected on sliding rail, and driving motor can drive and lead
Draw mechanism to slide on sliding rail, fixture be additionally provided on haulage gear, the slide being slidably connected with sliding rail is additionally provided on the sliding rail,
Slide is equipped with hydraulic oil container, hydraulic pump, sealing cover and pressure-control valve；One end of sealing cover is openend, and the other end is solid
The fixing end being scheduled on slide, openend are equipped with retaining mechanism, and pressure-control valve and hydraulic pump are installed in the fixation of sealing cover
End, and the outlet of the entrance of pressure-control valve and hydraulic pump is connected with the cavity of sealing cover；The slide, mold and dragger
Structure is successively set on pedestal, and the openend of sealing cover is opposite with collar extension, and the plug coordinates with extruding raw material pipe.
The principle of this programme drawing copper tubes device is：
When the device provided using this programme is processed extruding raw material pipe, first extruding raw material pipe one end should be contracted
Mouthful, then extruding raw material pipe necking end is inserted into mold, and plug is slipped into extruding raw material pipe, the non-necking of extruding raw material pipe
One end is inserted into sealing cover, is fixed sealing cover and extruding raw material pipe by retaining mechanism, then mold and slide are by extruding raw material
Pipe is propped.Start hydraulic pump, then hydraulic oil is entered by sealing cover in extruding raw material pipe, and push plug to mold, makes plug
Compress the inside of extruding raw material pipe；Under the control of pressure-control valve, the pressure in extruding raw material pipe remains constant always, and by
It is run always in hydraulic pump, hydraulic oil will be overflowed from pressure-control valve returns to hydraulic oil container, so as to the hydraulic pressure in extruding raw material pipe
Oil is always flowing.
The necking end of extruding raw material pipe is clamped by the fixture on haulage gear, then starts driving motor, then draws
Mechanism is slided on sliding rail, so as to generate tractive force to extruding raw material pipe.During haulage gear draws extruding raw material pipe,
Plug and mold always generate the inner side and outer side of extruding raw material pipe identical pressure, so as to ensure that internal diameter, outer diameter and wall
It is thick consistent.
This programme generate advantageous effect be：
（One）Pressure is generated to plug by hydraulic oil, plug is made to squeeze the inside of extruding raw material pipe, so as to eliminate use
In the setting of the bar of stationary core rod, therefore extruding raw material length of tube is no longer limited by bar, you can to extend extruding raw material pipe
Length so as to increase the continuity of process, improves processing efficiency.
（Two）In process, hydraulic oil always with core rod touch, and the friction of extruding raw material pipe and plug will generate it is big
The heat of amount, therefore hydraulic oil can absorb the heat, and hydraulic oil is constantly in extruding raw material Bottomhole pressure, so as to accelerate to dissipate
Heat；Hydraulic oil can also play lubricating action simultaneously.
Preferred embodiment one：It is advanced optimized as to base case, the plug center is equipped with threaded hole, haulage gear
On be further fixed on the screw rod that can be threadedly coupled with the threaded hole of plug.When haulage gear slides, screw rod will follow haulage gear
Mobile, since screw rod connect with core rod screw thread, plug is by rotation, so as to make the deformation of extruding raw material pipe evenly.Separately
Outside, the length of screw rod after the tubing of pull-out reaches required length, can be blocked depending on the length of required tubing, and
Haulage gear is returned, can continue to process.In preferred embodiment one, since screw rod is by tensile stress, and screw rod is being drawn
It will not be bent under the action of power, also not have fixed effect to plug, therefore plug can have larger length, the i.e. dress
Longer tubing can be processed by putting.
Preferred embodiment two：As advanced optimizing to preferred embodiment one, the surface of the plug is equipped with spiral lead
Oil groove, for plug in rotation, hydraulic oil can be expressed to the contact position of plug and extruding raw material pipe by oil guide groove, so as to increase contact
The oil mass at place, further reduces frictional force.
Preferred embodiment three：As advanced optimizing to preferred embodiment two, the retaining mechanism is expansion sleeve, and expansion sleeve is solid
It is good and easy to operate to determine effect.
Preferred embodiment four：As advanced optimizing to preferred embodiment three, support base is equipped between the slide and mold,
Support base is slidably connected with sliding rail, and support base is equipped with trip bolt.Since the length of extruding raw material pipe is longer, setting branch
Seat is supportted to being supported in the middle part of extruding raw material pipe, extruding raw material pipe to be prevented to be bent.In process, extruding raw material pipe
Length gradually shortens, and changes its position by slide bearings, and pass through trip bolt and be fixed, and can be in support base and squeeze
Press the middle part of mother tube.
Preferred embodiment five：As advanced optimizing to preferred embodiment four, the pedestal is equipped with the tooth for being parallel to sliding rail
Item, the driving motor is mounted on haulage gear, and is rotatably connected to and is engaged with rack and by driving motor on haulage gear
The traction gear of driving.The structure power transmission of preferred embodiment five is stablized, simple in structure, easy to operation, can effectively save cost.
