Abstract
A kind of steel frame polyethylene compound pipe electric melting sleeve framework positioning device.Mainly solve the problems, such as that existing electric melting sleeve framework positioning device is complicated for operation, influence stream and product quality, locating effect are bad.It is characterized by: the positioning screw (4) is 4, it is located at steel skeleton (1) two sides up and down, and positioning screw (4) end is located at the material-distributing hole (2) on steel skeleton (1) Nei, spring (5) are cased on the positioning screw (4), spring (5) both ends are withstood on respectively on positioning screw (4) external step and mold insert lid (3), and mold insert lid (3) is fixed on mold (8).Steel frame polyethylene compound pipe electric melting sleeve framework positioning device positioning is reliable, easy to operate, substantially reduces the use of part of plastic positioning nail, its influence to stream is reduced, to improve product quality.
Description
Technical field
The utility model relates to oil gas ground engineering, specifically a kind of steel frame polyethylene compound pipe electric melting sleeve skeleton
Positioning device.
Background technique
Steel skeleton polyethylene plastic composite pipe be a kind of inside by steel wire weld networking after, outside cladding polyethylene formation
A kind of compound tubing.The multiple tube relies primarily on electric melting sleeve connection, welds after possessing a steel plate punching inside electric melting sleeve
Tubulose steel skeleton made of connecing needs to guarantee that steel skeleton does not deviate position in electric melting sleeve injection molding in injection molding
Steel skeleton is positioned in the process.Existing positioning device is one steel positioning column of installation on skeleton, is then inserted into
In mold, it is aided with part of plastic positioning nail and realizes framework location, this positioning device is primarily present following problems: 1. increase steel skeleton
Cost of manufacture, complex process need to weld a steel positioning column base in skeleton extra openings；2. production operation process is complicated, steel is fixed
Position column needs that mutual disassembly, positioning post holes need to manually fill up, skeleton installation is mostly by experience；3. using more part of plastic positioning nail, influence
Polyethylene punch die speed, influences stream and product quality；4. locating effect is bad, anchor point is in material hole relative position, bone
Frame easily deviates.
Summary of the invention
In order to overcome, existing electric melting sleeve framework positioning device is complicated for operation, influences stream and product quality, positioning effect
The bad deficiency of fruit, the utility model provide a kind of steel frame polyethylene compound pipe electric melting sleeve framework positioning device, the reinforcing bar
The positioning of frame polyethylene compound pipe electric melting sleeve framework positioning device is reliable, easy to operate, stream is not influenced, to improve product
Quality.
The technical solution of the utility model is: a kind of steel frame polyethylene compound pipe electric melting sleeve framework positioning device, packet
Steel skeleton, positioning screw are included, the positioning screw is 4, is located at steel skeleton two sides up and down, and positioning screw end is located at
In material-distributing hole on steel skeleton, spring is cased on the positioning screw, both ends of the spring withstands on the step outside positioning screw respectively
And mold insert covers, and mold insert lid is fixed on mold.
Insert and cover half mold insert are respectively fixed on the mold, wherein insert top is connected with mold insert lid；
The positioning screw top passes through insert and mold insert lid.
The utility model has the following beneficial effects: the positioning device reduces plastics positioning due to taking above scheme
Nail, and the automatic rollback structure of positioning screw is combined, stream difficulty when polyethylene punch die is reduced, avoids generating positioning column
Hole keeps steel skeleton inner layer polyethylene thickness uniform, improves product quality, reduces risk of leakage；Reduce installation when operation, tear open
It unloads positioning column and fills up positioning three production process of post holes, improve working efficiency, reduce skeleton installation difficulty；It can be very good
It solves the problems, such as to cause skeleton to deviate because positioning is bad.
Detailed description of the invention
Fig. 1 is the main view of the utility model；
Fig. 2 is the left view (removal mold) of the utility model.
1- steel skeleton in figure, 2- material-distributing hole, 3- mold insert lid, 4- positioning screw, 5- spring, 6- insert, 7- cover half edge
Part, 8- mold.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Fig. 1, Fig. 2, a kind of steel frame polyethylene compound pipe electric melting sleeve framework positioning device, including steel skeleton 1,
Positioning screw 4 is equably provided with material-distributing hole 2 on steel skeleton 1, and the positioning screw 4 is 4, is located at steel skeleton about 1 two
Side, and two sides are arranged symmetrically up and down.Steel skeleton 1 is placed in inside mold 8, and insert 6 is respectively fixed on the mold 8 and is determined
Mould mold insert 7, similarly, insert 6 and cover half mold insert 7 are also that upper and lower two sides are arranged symmetrically.It is carried out by taking superstructure as an example below
Illustrate, 6 top of insert is connected with mold insert lid 3,4 lower end of positioning screw in the material-distributing hole 2 on steel skeleton 1,
4 top of positioning screw passes through insert 6 and mold insert lid 3, is equipped with boss in the middle part of positioning screw 4, and boss top is cased with spring 5,
5 upper end of spring is withstood on mold insert lid 3.
Before injecting polyethylene, positioning screw 4 is inserted into material-distributing hole 2 under the spring effect of spring 5, to steel skeleton
1 plays positioning action.It, can be with using the mould cavity pressure for reaching peak value after packing stage positioning screw 4 completes positioning function
Make 4 automatic rollback of positioning screw, so that stream be made to automatically flow into material-distributing hole 2, do not generate positioning post holes, realizes electric smelting product one
Molding, improves product quality.
