Description
Technical field
The present invention relates to tubular object extruding equipment, specifically, being related to a kind of tubing cut-out equipment and tubing cutting-off method.
Background technology
In the processing and manufacturing of tubular member, need that long pipe is first cut into fixed length pipe, then carry out fixed length pipe curved
The working processes such as pipe, flaring, necking, tube expansion and punching.Currently, commonly use the machining process such as sawing machine cut-out, abrasive cutting-off and
Tubing is cut into predetermined length by processing method for stamping.The advantages of machining process is section stable quality, but due to it
Processing efficiency is relatively low and is difficult to carry out mass production；In contrast, efficient to produce the advantages of processing method for stamping
And it is convenient for mass production, but be easy to cause tube wall in cut-out and be crushed so that section, which generates, to distort, is crooked.
Shearing method referred to as punching method, as a kind of processing method for stamping, using mold to tubing on forcing press
It is cut off；It in cutting-off process, is contacted with tube wall based on the blade tip of cutter and compels to bring it about plastic deformation, while point of a knife pressure
Enter in tube wall, as point of a knife enters the increase of tube wall depth, leads to pipe wall material moment embrittlement, and utilize cutter side edge and cavity plate
Side edge starts to shear tube wall, until completely cutting through tubing.In cutting-off process, as shown in Figure 1, utilizing cutter blades 01
Blade apex angle 011 when being punched the top 021 of tubing 02, the extruding of blade apex angle 011 easily makes at the top of tube wall 021 to flatten and cause
Cut off area distortion.
In order to preferably solve the problems, such as that when starting punching easily flattening occurs for tubing and leads to cut off area distortion, notification number
A kind of Die for cutting tube is disclosed for the patent document of CN2414865Y, includes for tubing to be clamped referring to its attached drawing
Sandwich mold unit 2, for tubing wait for off-position shape the notch unit of notch with for will at aforementioned off-position
The cutting unit of tubing cut-out.As shown in its Figure of description 1, sandwich mold unit 2 includes left clamp mould and is driven by actuator
The dynamic clamping in the right side；Cutting unit includes the cutter blades 1 driven by actuator, and cutter blades are in cone-shaped, and blade is towards left and right
Both sides；Notch unit be tool-broaching mechanism, include the broaching tool pedestal 3 with emptying aperture 4, the sliding block 5 equipped with hole 10, nicking blade 6 and
Driving column 7, sliding block 5 are laterally actively socketed on broaching tool pedestal 3, and nicking blade 6 is fixed on sliding block 5, and driving column 7 is by vertical column cap
8 and inclined shaft 9 constitute, hole 10 includes coordinating to tilt hole portion 11 and the vertical component 12 that coordinate with column cap 8 with shaft 9, logical
The coupling for crossing driving column 7 and hole 10, so as to utilize the vertical driver for driving cutter 1 to move up and down to be sequentially driven notch
Blade 6 tubing wait in off-position transversely pull out incision notch, then nicking blade 6 is driven to be cut along reverse movement to exiting
Disconnected position then drives cutter blades 1 vertically from incision notch incision tubing to cut off tubing.
Aforementioned cut-out equipment cuts out incision notch in the cut-out inlet of tubing in advance by adding notch unit, can have
Avoid the problem that effect that tubing easily occurs to flatten and cause to cut off area distortion when starting punching.But utilizing blade apex angle 011
When being punched out to tube wall bottom 022, burr and diagonal distortion can be generated at section, and and easily in incision incision production
Raw diagonal distortion.In addition, in the prior art, need to be pierced into tube wall by blade apex angle 011 and obtain initial incision, with tube wall
It thickens, blade apex angle is easily made to generate tipping, in order to avoid tipping and the service life of raising cutter blades 01, it is common practice that increase
Add the angle of blade apex angle, but with the increase of blade apex angle, be pierced into required pressure bigger, and be easy to cause deforming tops bigger,
And there is burr and diagonal distortion to more maximum probability at bottom.
Invention content
The main object of the present invention is to provide a kind of tubing cut-out equipment, is improving the same of its cutter blades service life
When, improve the forming quality of tubing section；
It is a further object of the present invention to provide a kind of tubing cutting-off methods used suitable for aforementioned tubes cut-out equipment.

Dynamic clamping is mobile towards both sides and discharges the clamping to tubing 03, then controls discharge unit by fixed length pipe from sandwich mold unit 2
It pulls out, and is positioned in predetermined collector.
During controlling two dynamic clampings openings, 511 retract cylinder 510 of piston rod is driven, with 511 quilt of piston rod
In retract cylinder 510, since cylinder body 510 is at least unfettered in the X-axis, 511 opposing cylinder 510 of piston rod of retraction moves
It is to pull right dynamic clamping 22 to push a left side far from tubing, and by connection guide 53 towards by moving right by push-pull rod 52 as effect
Dynamic clamping 21 is moved to right dynamic clamping 22 towards moving right, until the inner cavity with right lateral cell wall 101 towards moving left far from tubing
Wall against when, the dynamic clamping in the right side 22 will be located at releasing position, i.e. the internal chamber wall of right lateral cell wall 101 constitute make in the present embodiment it is right dynamic
Clamping 22 is in the locating piece of releasing position, after being retracted to predetermined length with piston rod 511, shows that left dynamic clamping 21 is also located
In releasing position.
In the present embodiment, since when forming cuts out notch, two blade parts of nicking blade 33 are simultaneously and right
Claim ground to be punched out tubing 03, flush shear force is symmetrically loaded to tube wall both sides, with unilateral application slicing power in the prior art
It compares, the diagonal distortion problem of section can be effectively reduced.
