Dress.
Background technology
It is one of basic connected mode of steel-plastics composite pipe that groove connects, and typically utilizes grooving machine that steel pipe is carried out rolling and adds
Work is to form groove at steel tube end part.The grooving machine sold on existing market includes termination trench processing tool and rolling device.
Its occupation mode is: the steel pipe that will process is placed on termination trench processing tool, and termination trench processing tool drives steel simultaneously
Pipe rotates, and then uses rolling device to exert a force steel pipe, and milled head extruding steel pipe forms annular ditch groove, and this equipment can only roll
Steel pipe.But when steel-plastics composite pipe is carried out groove processing, the wall thickness of steel-plastics composite pipe includes thickness of steel pipe and moulds thickness of pipe wall,
Because recess width and the depth dimensions of existing grooving machine are little, during rolling steel-plastics composite pipe, relatively mould layer and play shear action.Cause steel
Moulding separation, mould a layer crack damage, time serious, whole circle such as comes off at the phenomenon.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of end for steel-plastics composite pipe
Portion's groove processing frock, this processing tool can be effectively ensured steel plastic compount pipe end rolling annular trench and mould layer and be not destroyed.
The purpose of this utility model realizes by the following technical solutions:
A kind of termination trench processing tool for steel-plastics composite pipe, described steel-plastics composite pipe includes steel pipe layer and is coated in
Layer is moulded on steel pipe layer inwall；Described termination trench processing tool includes the cylinder being installed in rotary shaft；The one of described cylinder
End extends outward a step, and described step, for positioning steel-plastics composite pipe in the axial direction, prevents steel-plastics composite pipe from adding man-hour
It is moved；Offer one on this cylinder, along rotary shaft circumferentially extending groove, described groove, cylinder is divided into two parts, away from
The part of step is supporting part, and the outer peripheral face of this supporting part is provided with annular knurl, the arranging of annular knurl can increase steel-plastics composite pipe with
Frictional force between termination trench processing tool, prevents steel-plastics composite pipe from adding generation in man-hour slip relatively；The width of described groove
Degree adds 2 times of steel-plastics composite pipes and moulds the thickness of layer, and the degree of depth of described groove adds 1 times of steel-plastics composite pipe and moulds the thickness of layer
Preferably, described step is in the form of a ring.
Preferably, the outer peripheral face of described supporting part length vertically is more than 100mm.
Preferably, described annular knurl is divided into three sections vertically, and each section of annular knurl length vertically is not less than 30mm.
Compared to existing technology, the beneficial effects of the utility model are:
Termination trench processing tool for steel-plastics composite pipe of the present utility model, makes the width of groove by machining
Adding 2 times of steel-plastics composite pipes and mould the thickness of layer, the degree of depth adds 1 times of steel-plastics composite pipe and moulds the thickness of layer so that moulding steel
When multiple tube is processed, tube wall has more wider space diametrically, reduces the two side of groove for moulding layer
Extruding so that mould layer and be not easy crack damage；Secondly, by increasing the length of supporting part outer peripheral face so that steel-plastics composite pipe is subject to
During to extruding, lifting surface area increases, thus reduces the stress moulding layer, reduce further and moulds the probability that layer damages.
Accompanying drawing explanation
Fig. 1 is this utility model schematic cross-section for the termination trench processing tool of steel-plastics composite pipe；
Fig. 2 is this utility model termination trench processing tool for the steel-plastics composite pipe schematic diagram when processing groove.
In figure: 1, termination trench processing tool；10, groove；11, supporting part；12, step；2, rotary shaft；3, steel plastic compount
Pipe；30, steel pipe layer；31, layer is moulded；4, rolling device；40, milled head.
Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
Embodiment 1
As shown in Figure 1-2, a kind of termination trench processing tool 1 for steel-plastics composite pipe 3, described steel-plastics composite pipe 3 wraps
Include steel pipe layer 30 and be coated on steel pipe layer 30 inwall mould layer 31；Described termination trench processing tool 1 includes being installed on rotation
Cylinder on axle 2；One end of described cylinder extends outward a circular step 12, and described step 12 is for fixed in the axial direction
Position steel-plastics composite pipe 3, prevents steel-plastics composite pipe 3 to be moved man-hour adding；Offer one on this cylinder to prolong along rotary shaft 2 circumference
The groove 10 stretched, cylinder is divided into two parts by described groove 10, and the part away from step 12 is supporting part 11, this supporting part 11
Being provided with annular knurl (not shown) on outer peripheral face, arranging of annular knurl can increase between steel-plastics composite pipe 3 and termination trench processing tool 1
Frictional force, prevent steel-plastics composite pipe 3 from occurring man-hour relatively to slide adding；The width of described groove 10 adds 2 times of steel and moulds multiple
Closing pipe and mould the thickness of layer, the degree of depth of described groove 10 adds 1 times of steel-plastics composite pipe and moulds the thickness of layer.
Preferably, the outer peripheral face of described supporting part 11 length vertically is more than 100mm, increases supporting part 11 outer peripheral face edge
Axial length so that when steel-plastics composite pipe 3 is squeezed, lifting surface area increases, thus reduces the stress moulding layer 31.
Preferably, described annular knurl is divided into three sections vertically, and each section of annular knurl length vertically is not less than 30mm.So energy
Increase the frictional force between steel-plastics composite pipe 3 and supporting part 11 further.
As in figure 2 it is shown, this utility model is rolling annular ditch groove for the termination trench processing tool 1 of steel-plastics composite pipe 3
Time, first steel-plastics composite pipe 3 being enclosed within termination trench processing tool 1, one end of steel-plastics composite pipe 3 is connected to described step 12
On, the existence of annular knurl adds the frictional force between steel-plastics composite pipe 3 and supporting part 11；Under the drive of rotary shaft 2, steel is moulded multiple
Conjunction pipe 3 rotates together along with termination trench processing tool 1；Then rolling device 4 extrudes near steel-plastics composite pipe 3, milled head 40
Part corresponding with described groove 10 on steel-plastics composite pipe 3 so that the tube wall deformation of steel-plastics composite pipe 3 concave downward, from
And form annular ditch groove.
Termination trench processing tool 1 for steel-plastics composite pipe 3 of the present utility model, makes groove 10 by machining
Width adds 2 times of steel-plastics composite pipes and moulds the thickness of layer, and the degree of depth adds 1 times of steel-plastics composite pipe and moulds the thickness of layer so that right
When steel-plastics composite pipe 3 is processed, tube wall has more wider space diametrically, reduce the two side of groove 10 for
Mould the extruding of layer 31 so that mould layer 31 and be not easy crack damage；Secondly, by increasing the length of supporting part 11 outer peripheral face so that
When steel-plastics composite pipe 3 is squeezed, lifting surface area increases, thus reduces the stress moulding layer 31, reduce further and moulds layer 31
The probability damaged.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection of this utility model claim
Within the scope of.
