Abstract
The utility model discloses the PVC M double-wall corrugated pipe of a kind of online enlarging, including straight-tube portion and flared part, straight-tube portion inner wall smooth, outer wall is bellows-shaped, and flared part is two flat walls structure, and port is horn-like；Straight-tube portion and flared part are once machine-shaping structure on forming machine.The PVC M double-wall corrugated pipe of online enlarging of the present utility model, straight-tube portion and flared part are once machine-shaping structure on forming machine, it is not necessary to special pipe-expanding machine, save the production process of heating enlarging, reducing production equipment and the human input of heating enlarging, production cost substantially reduces.One-time formed tubing and enlarging, physical dimension concordance is good, it is to avoid use that heating enlarging exists when enlarging technique change, cause the situation that enlarging size is inconsistent, the sealing property of tubing improves.
Description
Technical field
This utility model relates to a kind of corrugated tube, relates in particular to a kind of PVC-M double-wall corrugated pipe.
Background technology
PVC dual-wall ripple pipe material is typically all the connected mode using socket joint, the making of its enlarging, prior art
Commonly used is the mode of post bake distending, the most first makes the tubing of certain length, at a special flare formation equipment
On, the side port section of tubing is heated, then would be heated to the port section of uniform temperature, with the enlarging of expanding
Mould, after dilating given size, then cooling and shaping makes the tubing with enlarging；The production method of this tubing, is producing
In the configuration of equipment, it is desirable to have special flare formation equipment, also need to supernumerary simultaneously, be used for operating enlarging apparatus, cause
Equipment investment increases and the waste of human resources.When enlarging technique change, the internal diameter of enlarging, the enlarging degree of depth and angle all can be sent out
Changing, causes enlarging size inconsistent and causes complaining, and serious meeting causes tubing socket joint difficulty or poor sealing to cause
Pipe leakage.
PVC-M double-wall corrugated pipe is a kind of with Corvic as primary raw material, adds certain proportion in formula
Impact-resistant modified auxiliary agent, through physical modification, the novel PVC dual-wall ripple pipe material of a kind of high tenacity of extruded production.
In low-temperature flexibility, there is an obvious advantage through impact-resistant modified PVC-M double-wall corrugated pipe, and there is extraordinary molding add
Work performance, thus, on pipe structure, also it is very different with traditional corrugated dual-wall hard PVC pipe.
Utility model content
In order to optimize the production technology of PVC dual-wall ripple pipe material, solve tradition PVC dual-wall ripple pipe and use
Heating flaring makes the drawback of tubing enlarging, and this utility model provides the PVC-M double-wall corrugated pipe of a kind of online enlarging.
The technical solution of the utility model is as follows:
The PVC-M double-wall corrugated pipe of a kind of online enlarging, it is characterised in that include straight-tube portion and flared part, straight tube
Internal partial wall is smooth, and outer wall is bellows-shaped, and flared part is two flat walls structure, and port is horn-like；Straight-tube portion and enlarging
Part is once machine-shaping structure on forming machine.
In a preferred embodiment of the present utility model, the outer wall of described straight-tube portion is for be connected mutually by some semicircles
The waveform configuration connect.
In a preferred embodiment of the present utility model, the outer wall of described straight-tube portion is by some trapezoidal interconnections
Waveform configuration.
In a preferred embodiment of the present utility model, the outer wall of described straight-tube portion is by some square interconnections
Waveform configuration.
The PVC-M double-wall corrugated pipe of online enlarging of the present utility model, straight-tube portion and flared part are on forming machine
It is processed and formed at one time structure, it is not necessary to special pipe-expanding machine, saves the production process of heating enlarging, reduce the life of heating enlarging
Product equipment and human input, production cost substantially reduces.One-time formed tubing and enlarging, physical dimension concordance is good, it is to avoid
Use that heating enlarging exists when enlarging technique change, cause the situation that enlarging size is inconsistent, the sealing property of tubing
Improve.
Feature of the present utility model see graphic and the most preferably embodiment the detailed description of this case and obtains clear
Ground is understood.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is fabrication processing figure of the present utility model.
Fig. 3 is the outer wall generalized section of straight-tube portion.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, under
Face is expanded on further this utility model in conjunction with specific embodiments.
As it is shown in figure 1, the PVC-M double-wall corrugated pipe of a kind of online enlarging, including straight-tube portion 10 and flared part 20, directly
Tube portion 10 inner wall smooth, outer wall is bellows-shaped, and flared part 20 is two flat walls structure, and port is horn-like；Straight-tube portion
10 with flared part 20 be once machine-shaping structure on forming machine.
See Fig. 3, in an embodiment of the present utility model, the outer wall of straight-tube portion be by some trapezoidal 11(or
Other shapes such as semicircle, square) waveform configuration that is interconnected together.
Production equipment of the present utility model includes plastic extruder, pipe mold, corrugated pipe forming machine, bellow forming
Block, pipe cutting machine and finished product piling bin.Wherein, bellow forming module is collectively constituted by straight tube module and enlarging module, on
State forming module to be arranged on corrugated pipe forming machine, along fixing track, shuttling movement in order.
See Fig. 2, for producing the PVC-M mixed ingredients of this tubing, extrude into tubing mould via plastic extruder plasticizing
Tool, compression molding is the pipe of molten condition, and pipe, under the effect of air pressure and forming machine vac sorb, is formed as and molding
The shape that inside modules cavity shape is consistent.
Forming module is shuttling movement, and when straight tube module enters into shaping position, the tubing now processed is ripple
Tube shape；Along with forming module moves, when enlarging module enters into shaping position, now pipe is blown into and module die cavity one
The flare form caused.
As it has been described above, the forming process of tubing is: at continuous flow procedure, PVC-M mixed ingredients is at plastic extruder and mould
Under the operation of tool, plasticating extrusion is pipe, and pipe, under the effect of air pressure and forming machine vac sorb, is shaped in molding
The tubing that inside modules cavity shape is consistent, the every loopy moving of forming module one week, process a PVC-M double-walled with enlarging
Corrugated pipe.Tubing cleaved machine fixed length cutting is finished product tubing, deposits in finished product piling bin.And so forth, tubing is completed
Produce.
Compared with the making flaring of the post bake distending commonly used with prior art PVC, eliminate heating
The production process of enlarging, and the one-time formed PVC-M double-wall corrugated pipe with enlarging, product structure dimensional uniformity
Good, tubing sealing property improves.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model also has respectively
Planting changes and improvements, these changes and improvements both fall within the range of claimed this utility model.This utility model requirement
Protection domain defined by appending claims and equivalent thereof.
