Abstract
A corrugated pipe molding middle die without an outer ring is formed by a first semi-circle die and a second semi-circle die, and the two semi-circle dies are combined to form a whole circle die through a tooth-shaped matched face. The structure of the tooth-shaped matched face is that a tenon and a mortise on the first semi-circle die are matched with a mortise and a tenon of the second semi-circle die, and molding faces of a corrugated pipe are prepared on inner edges of the semi-circle dies of the middle die. Compared with a sleeved-combined type die, the corrugated pipe molding middle die without the outer ring is simple in structure and saving in cost; and compared with a butt joint die, the corrugated pipe molding middle die saves connection constructional elements such as support lugs and threaded rods, and the strength is relatively high.
Description
Technical field:
The utility model relates to bellows industry moulding dock mould.
Background technology:
Mould is in order to limit the device of the shape and size of producing object.It mainly realizes the processing of article profile by the change of institute's moulding material physical state.In recent years, the die industry fast development is widely used in all trades and professions.The mould that uses in the bellows industry also is of a great variety, and commonly used have monoblock type, nested a, dock etc., and the range of application of every kind of mould is all different, each have their own advantages and disadvantages.Therefore, in the bellows actual production, usually be several moulds and deposit, when the bellows of compacting different size pattern, need to select dissimilar moulds.To guarantee that compressing bellows can satisfy specification requirement and physical dimension.
The utility model content:
The purpose of this utility model is that proposition is a kind of without mould in the corrugated pipe forming of outer ring.This mould belongs to the dock mould, and in the actual production manufacture process, easy accessibility, and intensity is higher can better guarantee waveform, physical dimension and specification requirement behind the corrugated pipe forming.
The technical solution of the utility model is:Without mould in the corrugated pipe forming of outer ring, should middle mould be the dock mould, consisted of by first, second two semicircle moulds, two semicircle moulds combine into a rounding die by the profile of tooth mating surface, described profile of tooth mating surface structure is as follows: the first semicircle mould is provided with a tenon one fourth of the twelve Earthly Branches, cooperate the second semicircle mould one fourth of the twelve Earthly Branches one tenon, mould semicircle mould inner edge is prepared with the moulding profile of bellows.The non-forming surface of mould cylindrical, symmetrical profile of tooth cooperation place, two ends all is drilled with fixed pin holes perpendicular to the one tenon place, a fourth of the twelve Earthly Branches of first, second two semicircle moulds, and inserts latch.Guarantee that the mold halves end face can on the same level face, satisfy production requirement.
The beneficial effects of the utility model:Mould has the advantage of easy accessibility compared to nested mould in this moulding; Compared to the mould of common dock, reduced again the connecting elements such as journal stirrup, screw rod, and intensity is higher, can better satisfy the corrugated pipe forming requirement.The utility model is compared to nested mould, and is simple in structure, saves cost; Compared to the mould of dock, saved the connecting elements such as journal stirrup, screw rod, and intensity is higher, better met the needs of the process of manufacturing.Have simple in structurely, easily make easy-to-dismount advantage.In actual production, can guarantee preferably the corrugated pipe forming needs, save production cost, shorten the production cycle.
Mould is easily made in this corrugated pipe forming, and is easy to assemble, and reliability is high.More than 20%, such as mould in the bellows of DN350mm, nested mould feed consumption 82kg adopts this structure feed consumption 68.2kg than nested mould economical with materials.Simplify greatly manufacturing process, shortened the production cycle, and physical dimension and the form and position tolerance of more effective assurance moulding bellows.
Description of drawings:
Fig. 1: for the utility model without mould upper mold section in the corrugated pipe forming of outer ring (the first half module) schematic diagram;
Fig. 2: for the utility model without mould female die in the corrugated pipe forming of outer ring (the second half module) schematic diagram;
Fig. 3: for the utility model without module dress, form removal schematic diagram in the corrugated pipe forming of outer ring;
Fig. 4: being A-A sectional view among Fig. 3, is that the utility model is without module dress, form removal top view schematic diagram in the corrugated pipe forming of outer ring.
The specific embodiment:
Below with reference to the accompanying drawings explanation,Number among the figure: upper mold section (the first half module) 1, female die (the second half module) 2, moulding profile 3, fixed pin holes 4.Without mould in the corrugated pipe forming of outer ring, belong to the dock mould.Be made of first, second two semicircle moulds, the mould inner edge is prepared with the moulding profile of bellows.
Two semicircle moulds combine by the profile of tooth mating surface.Should middle mould be the dock mould, formed by first, second two semicircle moulds, two semicircle moulds combine into a rounding die by the profile of tooth mating surface, and described profile of tooth mating surface is that the first semicircle mould has a tenon one fourth of the twelve Earthly Branches to cooperate the second semicircle mould one fourth of the twelve Earthly Branches one tenon at least.Can be that two tenons, two fourths of the twelve Earthly Branches cooperate two fourths of the twelve Earthly Branches, two tenons, the cross sectional shape of the fourth of the twelve Earthly Branches, tenon not be limit, and can be rectangle or triangle yet, can be the shape such as trapezoidal yet.
1. according in GB16749-1997 " pressure vessel corrugated-type expansion joint " standard, the waveform size of bellows and forming materials rebound coefficient calculate the moulding R arc of mould in the moulding, thereby determine the thickness δ of middle mould; Determine wave height Hmax according to bellows different size and performance requirement, thereby determine the excircle dimension of mould in the moulding.Cut out the mating surface of two half-formed middle moulds with wire cutting machine.Mating surface and the required precision of moulding profile are higher.
2. in the non-forming surface 3 of mould cylindrical, symmetrical profile of tooth cooperation place, two ends, each bores two fixed pin holes 4.
Claims (2)
1. without mould in the corrugated pipe forming of outer ring, it is characterized in that: consisted of by first, second two semicircle moulds, two semicircle moulds combine into a rounding die by the profile of tooth mating surface, described profile of tooth mating surface structure is as follows: the first semicircle mould is provided with a tenon one fourth of the twelve Earthly Branches and cooperates the second semicircle mould one fourth of the twelve Earthly Branches one tenon, and the inner edge of mould semicircle mould is prepared with the moulding profile of bellows.
2. according to claim 1 without mould in the corrugated pipe forming of outer ring, it is characterized in that: the one tenon place, a fourth of the twelve Earthly Branches perpendicular to first, second two semicircle moulds all is drilled with fixed pin holes and is provided with latch.
