Abstract
The utility model relates to a super large bore HDPE winding arrangement wall pipe rolls tube formwork utensil, it includes a cylinder shaped steel section of thick bamboo, steel cylinder one end is equipped with the bellmouth, the bellmouth is female a mouthful of steel cylinder, and mould no. 1 is served and will be made a sloping platform and exceed partlyly than mould wall, be provided with the skeleton that is used for the support die cylinder along cylinder shaped steel section of thick bamboo axis in the steel cylinder, the skeleton divide into upper and lower components of a whole that can function independently skeleton two parts, and upper and lower components of a whole that can function independently skeleton is connected with a cylinder shaped steel section of thick bamboo respectively, is equipped with between upper and lower components of a whole that can function independently skeleton that the control skeleton opens or the structure that opens and shuts of crimple, opens along axial direction surely to go out three seams on cylindrical steel cylinder. The utility model provides a be the technical problem of DN3500 super large bore high density polyethylene tubular product mould vacancy.
Description
Technical field
This utility model relates to Mold Making field, is specially a kind of heavy caliber HDPE winding structure pipe drum die.
Background technology
High density polyethylene (HDPE) winding structure pipe also known as carat pipe in American-European countries through the engineer applied of more than 70 years, be up to the present still the plastic drain pipe product of most significant end in the world.Recent year carat pipe do not have range of application extensive all the more, especially the carat pipe of super large caliber bridge, culvert the aspect advantage such as construction clearly.But the making of its grinding tool when making of super large caliber carat pipe is a difficult point.
Utility model content
The purpose of this utility model is that a kind of heavy caliber HDPE winding structure pipe drum die of offer, and which solving is the technical problem of DN3500 super large caliber hdpe pipe mould vacancy.
Technical solutions of the utility model are as follows:
A kind of super large caliber HDPE winding structure pipe drum die, it includes a column type steel cylinder, and steel cylinder one end is provided with bellmouth, described bellmouth, refers to female mouth of steel cylinder, mould one end to be made a sloping platform and exceeds a part than mold wall；In steel cylinder, the skeleton for supporting mold drum it is provided with along column type steel cylinder axis, skeleton is divided into upper and lower split skeleton two parts, upper and lower split skeleton connects with column type steel cylinder respectively, it is provided with between upper and lower split skeleton and controls the opening-closing structure that skeleton opens or tightens, cylindrical steel cylinder is in axial direction opened and cuts out three seams, mould open/close can be made flexible.
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, accomplishes that skeleton can connect with steel cylinder.
The beneficial effects of the utility model are as follows:
This utility model just can produce DN3500 super large caliber relatively easily by changing mold, the high density polyethylene (HDPE) structured wall popes of different-stiffness, drum die is the key component that extrusion is Wrapping formed, in hot state, mould rotates around causing plastic tube, and the slight change of mould inside structure makes high-density polytene pipeline mould hit new peak again.
This utility model is belonging to an innovation of the mould pith at the high density polyethylene (HDPE) winding structure pipe producing diameter DN3500, the DN3500 production tube being in the past difficult to is rolled off the production line in the innovation of mould process, during causing, mould can screw and can diminish could the demoulding.This just determines mould inside certain structure, pulls internal each parts to move axially under extraneous effect so that it is producing diameter change, folding is freely.
Comparing small-bore mould, inner components is not simple amplification, reduces.Again can be interrelated between each part dimension, the most all can affect the concordance of its action, therefore, machining accuracy mutually. the precision of assembling and the heat-resistant anti-fatigue performance of material, be the key determining mould success or failure.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
This utility model one super large caliber HDPE winding structure pipe drum die as shown in drawings, this drum die includes a column type steel cylinder 1, cylindrical steel cylinder 1 one end is provided with bellmouth 2, described bellmouth, refer to female mouth of cylindrical steel cylinder, mould one end to be made a sloping platform and exceeds a part than mold wall；In cylindrical steel cylinder, the skeleton for supporting cylindrical steel cylinder it is provided with along column type steel cylinder axis, skeleton is divided into upper and lower split skeleton 3,4 two parts, upper and lower split skeleton 3,4 connects with cylindrical steel cylinder 1 respectively, it is provided with between upper and lower split skeleton 3,4 and controls the skeleton opening-closing structure 5 that opens or tighten, cylindrical steel cylinder 1 is in axial direction opened cut out and can make mould open/close three seams 6 flexibly.
The utility model discloses the processing technology of a kind of super large caliber DN3500 high density polyethylene (HDPE) winding structure pipe mold, first steel are selected, mould to withstand 180 °～the high temperature of 200 ° in process of production, the column type steel cylinder of a length of 7 meters of an a diameter of DN3500 is made with the steel chosen, steel cylinder one end band bellmouth, then i.e. makes annealing treatment after material blanking, can eliminate stress, again with machine tooling, it is ensured that part is indeformable.Being connected to by the major axis of 5 7M by two-piece unit skeleton skeleton, for solving the axis hole positional precision problem of skeleton, develop drill jig specially, with drill jig positioning shaft hole position, it is ensured that axis hole position accurately consistent, the raising for assembly precision lays the first stone.Finally 13 skeletons are filled in cylinder after outside assembles again, 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 is flexible.
The utility model has the advantage of and saved cost, can recycle, the technological process of production is reasonable, and the drum die through developing, develop has been used for producing, and all products all conform to quality requirements.In mould trial-manufacturing process, we have accumulated rich experience, the technique having found out a set of maturation, has filled up the blank of China's large-bore plastics Making mold.
