Abstract
The utility model discloses a kind of Full-automatic tube bending machine internal-expansion type collet, on bending machine fuselage, the clamping device includes internal-expansion type collet, closing sleeve, screw and interior expansion core rod, internal-expansion type collet, closing sleeve are sequentially provided with the bending machine fuselage, the internal-expansion type collet is fixed on bending machine fuselage by internal thread, and the closing sleeve promotes movement by the cylinder on bending machine；The interior expansion core rod is by screw and closing sleeve fixed lock.The Full-automatic tube bending machine internal-expansion type collet that the utility model is provided, in the case where device structure is not changed, the purpose for reaching pipe fitting clamping using internal-expansion type clamping device, need not increase technique end, reach material-saving, reduce labor hour, reduce cutter consumption, the purpose of reduces cost.
Description
Technical field
The utility model belongs to bending machine equipment technical field, more particularly to Full-automatic tube bending machine internal-expansion type collet.
Background technology
More than the clamping device of existing Full-automatic tube bending machine using external clamping collet technical scheme, its operation principle is
Cylinder on Full-automatic tube bending machine promotes part closing sleeve to move forward and backward, and external clamping collet is maintained static, when cylinder to
Before when pushing away, part closing sleeve is moved forward, and makes external clamping collet by the taper being engaged with external clamping collet
Clamp position inwardly to press, so as to Clamp blocks pipe fitting is cylindrical.When cylinder is drawn back, part closing sleeve is moved rearwards by, with outer clip
The taper that formula collet is engaged is separated from, and external clamping collet is flared out returning to normal shape by the elasticity of itself
State, so that unclamp part pipe fitting.
But external clamping collet technical scheme be present：If wanting curved pipe fitting last curved below straight
Line segment less than 180mm, curved last curved when, external clamping collet forward feeding when can collide the wrinkle resistant of bending die
Block, feeding just send not in place, so as to bend pipe cannot be completed.The bend pipe of such pipe fitting is completed, technique end can only be increased, bend pipe is treated
After the completion of remove elongated portion pipe fitting again.So both waste of materials, increases again and goes the operations such as technique end, chamfering deburring, so as to
Increase labor hour, cutter consumption, equipment etc., improve cost.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of Full-automatic tube bending machine internal-expansion type collet, is not changing
In the case of becoming device structure, the purpose that pipe fitting is clamped is reached using internal-expansion type clamping device, technique end need not be increased, section is reached
Material saving, reduction labor hour, minimizing cutter consumption, the purpose of reduces cost.
In order to solve above-mentioned technical problem, the technical solution of the utility model is：
A kind of Full-automatic tube bending machine pipe fitting cramping arrangement, on bending machine fuselage, wherein described clamping device includes
Internal-expansion type collet, closing sleeve, screw and interior expansion core rod, are sequentially provided with internal-expansion type spring clip on the bending machine fuselage
Head, closing sleeve, the interior expansion core rod is by screw and closing sleeve fixed lock.
Preferably, the internal-expansion type collet is fixed on bending machine fuselage by internal thread.
Preferably, the endoporus insertion internal-expansion type collet of the pipe fitting.
Preferably, the internal-expansion type collet front end is evenly divided into 4 lobes, for Clamp blocks pipe fitting inner wall.
Preferably, it is taper at the internal-expansion type collet endoporus and interior expansion core rod cooperation, when interior expansion core rod is to reach
Dynamic, the taper being engaged by internal-expansion type collet is flared out internal-expansion type collet clamping position, so as to clamp zero
Part pipe fitting inner wall.
Preferably, the closing sleeve promotes movement by the cylinder on bending machine fuselage, and closing sleeve is with cylinder
Advance, retrogressing are done movable.
A kind of Full-automatic tube bending machine pipe fitting cramping arrangement of the utility model, in the case where device structure is not changed, passes through
The clamping mode clamped using internal-expansion type, the problems and disadvantages for solving prior art presence using most easy method.
Full-automatic tube bending machine internal-expansion type collet clamps the purpose of pipe fitting when not only achieving bend pipe, and due to internal-expansion type collet
Be clamp pipe fitting inner wall, be not higher by tube outer diameter, during feeding, just got out of the way wrinkle resistant piece of bending die, so as to by pipe fitting feeding in place
Complete bend pipe.The utility model Full-automatic tube bending machine pipe fitting cramping arrangement, need not increase technique end, reach material-saving, reduction
Labor hour, minimizing cutter consumption, the purpose of reduces cost.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- internal-expansion type collets；2- closing sleeves；3- screws；Expansion core rod in 4-；5- pipe fittings.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.Here it should be noted that
For the explanation of these embodiments is used to help understand the utility model, but do not constitute to restriction of the present utility model.This
Outward, as long as involved technical characteristic in the utility model disclosed below each embodiment does not constitute conflict each other
Can just be mutually combined.
Embodiment
As shown in figure 1, the Full-automatic tube bending machine pipe fitting cramping arrangement described in the present embodiment, on bending machine fuselage.
Clamping device includes internal-expansion type collet 1, closing sleeve 2, screw 3 and interior expansion core rod 4, is sequentially provided with interior on bending machine fuselage
Expanding collet 1, closing sleeve 2, internal-expansion type collet 1 by internal thread on the bending machine fuselage, pipe fitting 5 interior
Internal-expansion type collet 1 is inserted in hole, and interior expansion core rod 4 is by screw 3 and 2 fixed lock of closing sleeve.
During work, when the cylinder on Full-automatic tube bending machine fuselage promotes forward closing sleeve 2 to move forward, interior expansion core is driven
Rod 4 is moved forward, and the taper being engaged by internal-expansion type collet 1 makes the clamping position of internal-expansion type collet 1 (divided
Into 4 lobes) it is flared out, so as to clamp 5 inwall of pipe fitting.When cylinder is drawn back, closing sleeve 2 is moved rearwards by, and drives interior expansion core
Rod 4 is moved rearwards by, and the taper being engaged with internal-expansion type collet 1 is separated from, elasticity of the internal-expansion type collet 1 by itself
Inwardly resilience returns to normal condition, so as to unclamp pipe fitting 5.
Embodiment of the present utility model is explained in detail above in association with accompanying drawing, but the utility model is not limited to be retouched
The embodiment that states.For a person skilled in the art, in the case of without departing from the utility model principle and spirit, right
These embodiments carry out multiple changes, modification, replacement and modification, still fall within protection domain of the present utility model.
