Abstract
The invention discloses a manufacturing process for an ultra-large-aperture HDPE winding structure wall tube roller mold. By means of the process, the technical problem of the gap of DN3500 ultra-large-aperture high-density polyethylene tube molds is solved. DN3500 ultra-large-aperture high-density polyethylene structural wall tubes with different rigidity can be produced easily by replacing the mold. The roller mold is a key part for extrusion winding molding. In a hot state, the mold rotates to wind and form a plastic tube. The high-density polyethylene tube mold reaches a new height through slight change of an internal structure of the mold.
Description
Technical field
The present invention relates to Mold Making field, be specially a kind of heavy caliber HDPE winding structure pipe cylinder mould
The manufacture craft of tool.
Background technology
High density polyethylene (HDPE) winding structure pipe also known as carat pipe in American-European countries through more than 70 years
Engineer applied, is up to the present still the plastic drain pipe product of most significant end in the world.Recent year gram
Trombone slide do not have range of application extensive all the more, especially the carat pipe of super large caliber is in bridge, the side such as construction of culvert
Face advantage is clearly.But the making of its grinding tool when making of super large caliber carat pipe is a difficult point.
Summary of the invention
The goal of the invention of the present invention is that the system providing a kind of heavy caliber HDPE winding structure pipe drum die
Making technique, which solving is the technical problem of DN3500 super large caliber hdpe pipe mould vacancy.
Technical solution of the present invention is as follows:
The manufacture craft of a kind of heavy caliber HDPE winding structure pipe drum die the steps include:
The first step, selects steel, and steel to withstand 180 DEG C～the height of 200 DEG C in mould production process
Temperature, makes the column type steel cylinder of a length of 7 meters of an a diameter of DN3500, steel cylinder one end with the steel chosen
Band bellmouth；
Second step, material i.e. makes annealing treatment after blanking, can eliminate stress, then with machine tooling, protect
Demonstrate,prove part indeformable；
13 identical skeletons are connected to by the 3rd step by the major axis of 5 7M, with drill jig positioning shaft hole position
Putting, it is ensured that axis hole position accurately consistent, the raising for assembly precision lays the first stone；
4th step, fills in column type steel cylinder 13 skeletons again after outside assembles, finds bone outside cylinder accurately
Rack position is welded, and in axial direction cuts out three seams on cylindrical steel cylinder；13 identical connecting rods divide
Not linked together with power transmission shaft by 13 skeletons, it is ensured that mould cylindrical, mould open/close is flexible.
Wherein said bellmouth, refers to female mouth of tubing, mould one end to be made a sloping platform higher than mold wall
Go out a part
Described skeleton, refers to that mould inside is for supporting the structure of steel product of mold drum
Described drill jig, refers to that average mark is made into 13 parts on 7 meters of long steel cylinders, separates 13 some punchings,
Accomplish that skeleton can connect with steel cylinder.
Beneficial effects of the present invention is as follows:
The present invention just can produce DN3500 super large caliber relatively easily by changing mold, different-stiffness highly dense
Degree polyethylene structure wall pipe, drum die is the key component that extrusion is Wrapping formed, in hot state, mould
Rotating around causing plastic tube, the slight change of mould inside structure makes high-density polytene pipeline mould hit new peak again.
The mould that the present invention is belonging at the high density polyethylene (HDPE) winding structure pipe producing diameter DN3500 is important
One innovation of part, the innovation of mould process rolls off the production line the DN3500 production tube being in the past difficult to, around
During cause, mould can screw and can diminish could the demoulding.This just determines mould inside to have certain
Structure, pulls internal each parts to move axially under extraneous effect so that it is produce diameter change, and folding is certainly
As.
Comparing small-bore mould, inner components is not simple amplification, reduces.Between each part dimension
Again can be interrelated, the most all can affect the uniformity of its action, therefore, machining accuracy mutually. assembling
The heat-resistant anti-fatigue performance of precision and material, is the key determining mould success or failure.
Detailed description of the invention
It is once the detailed making enforcement step of the present invention:
The first step, selects steel, and mould to withstand 180 °～the high temperature of 200 ° in process of production, with choosing
Good steel make the column type steel cylinder of a length of 7 meters of an a diameter of DN3500, steel cylinder one end band bellmouth.
Second step, i.e. makes annealing treatment after material blanking, can eliminate stress, then with machine tooling, it is ensured that
Part is indeformable.
13 identical skeletons are connected to by the 3rd step by the major axis of 5 7M, for solving 13 skeletons
Axis hole positional precision problem, develops drill jig specially, with drill jig positioning shaft hole position, it is ensured that axis hole position
The most consistent, the raising for assembly precision lays the first stone.
4th step, 13 skeletons are filled in cylinder after outside assembles again, outside cylinder, finds skeleton position accurately
Put and weld, and in axial direction cut out three seams on cylindrical steel cylinder；13 identical connecting rods are respectively by 13
Individual skeleton links together with power transmission shaft, it is ensured that mould cylindrical, and mould open/close is flexible
The invention discloses the making of a kind of super large caliber DN3500 high density polyethylene (HDPE) winding structure pipe mold
Technique, first selects steel, and mould to withstand 180 °～the high temperature of 200 ° in process of production, with choosing
Steel make the column type steel cylinder of a length of 7 meters of an a diameter of DN3500, steel cylinder one end band bellmouth, so
I.e. make annealing treatment after rear material blanking, can eliminate stress, then with machine tooling, it is ensured that part is constant
Shape.Again 13 identical skeletons are connected to by the major axis of 5 7M, for solving the axis hole position of 13 skeletons
Put precision problem, develop drill jig specially, with drill jig positioning shaft hole position, it is ensured that accurate the one of axis hole position
Causing, the raising for assembly precision lays the first stone.Finally 13 skeletons are filled in cylinder after outside assembles again
In, outside cylinder, find frame position accurately weld, and in axial direction cut out three seams on cylindrical steel cylinder；
13 skeletons are linked together by 13 identical connecting rods respectively with power transmission shaft, it is ensured that mould cylindrical, mould open/close
Flexibly
It is an advantage of the current invention that to have saved cost, can recycle, the technological process of production is reasonable, through opening
The drum die send out, developed has been used for producing, and all products all conform to quality requirements.Manufactured experimently at mould
Cheng Zhong, we have accumulated rich experience, the technique having found out a set of maturation, have filled up China's heavy caliber
The blank of plastic mold manufacture.
