Description
Technical field
The present invention relates to a kind of helical element, such as screw, nut, sleeve part, pipe plug, tube connector etc., this helical element has and is positioned at screw thread on matrix and at least one circumferential seal (such as O shape ring) and/or at least one thread premium device, and described thread premium device exists the torque of outwarding winding that improve described helical element when spiral is connected between described helical element with another component.
Background technique
This thread premium device for screw or helical element is known.Such as, in the known safty device of the aforementioned type of introducing to the market as ProductName with Klemm-tight (TM trade mark) in one, in the screw thread of screw matrix, milled out a groove, and in this groove press-in have one can the line of resiliently deformable.The line be made up of a kind of carbon fibre core with plastic casing is applied especially at this.Helical element and another component formed spiral be connected time, this line improves the torque of outwarding winding of described helical element.Circumferential seal, such as O shape ring, first achieves sealing function, and meanwhile, its existence can also reach the secondary function of the torque of outwarding winding improving helical element.
The fact shows, adopts the known helical element of the described type of beginning not to be that a kind of long-time spiral reliably of total energy formation connects.In addition, adopt the cost of extraordinary line also very high.
Summary of the invention
Basic order of the present invention is to provide a kind of helical element can produced with minimum process costs starting described type herein, and this helical element guarantees to form a kind of long-time spiral highly reliably with another component and is connected.In addition, this helical element also should be able to be assembled easily when setting up spiral and connecting, and its functional safety should be able to be kept under the effect of the such as environmental factor such as temperature, pressure.
According to the present invention, the object of the above-mentioned helical element about described type is achieved by following manner, that is, adopt by hetero-polymer material with multi-part injection molding technological forming and the matrix be connected to each other and circumferential seal and/or thread premium device.
Helical element is according to this structure of the present invention, make it can in an advantageous manner completely only in a processing machine or mould die casting form, wherein, need the number of assembling steps of design according to prior art, itself and the step that the independent wire safty device processed are assembled together also can save by such as milling groove.In addition, by the connection of a kind of material fit (stoffschluessig), such as with the connection that multi-part injection molding technique is formed, at the matrix of helical element with to form one between circumferential seal and/or thread premium device very stable and be connected reliably.
Described matrix preferably can be made up of thermoplasticity or thermosets respectively, and thread premium device and/or circumferential seal are preferably by one or more elastic materials, as thermoplastic elastomer (TPE) composition.For matrix, especially preferred material is polyoxymethylenes (POM) or polyamide (PA), particularly fibre-reinforced polyamide, and for thread premium device and/or circumferential seal especially preferably silicone rubber and/or fluorine rubber (FKM, MVQ, FVMQ), but also ethylene propylene diene rubber (EPDM) and/or polyurethane (PUR) can be used, such as thermoplastic polyurethane (TPE-U).
Injection molding (English: injectionmolding) is a kind of discrete basic forming method for plastics.Utilize injection molding, can manufacture in large quantities the direct applied moulded parts of industrial energy with higher precision.For this reason, corresponding material in other words moulding material is processed by plasticizing in an injection unit of injection molding machine, and is injected in an injection molding mould.Modern injection molding machine utilizes screw rod to carry out work, and moulding material is plastified processing, carries and inject among mould by this screw rod.At the chamber of mould in other words in shaping cave, polymer material is solidified, and profiled member can be taken out from mould thus.The situation of the volume-diminished occurred when solidifying, can be made up by the mode imposing dwell pressure (Nachdruck) before it is removed to a certain extent.
By injection molding, can to thermoplastic, thermosetting plastics and elastomer are processed.Here, when carrying out injection molding to thermoplastic, the fibrous material of bag can be adopted, the profiled member relatively with more high strength can be produced thus.As fiber, can consider to adopt isotropic fiber, such as glass fibre, and/or anisotropic fiber, such as carbon fiber or aramide-fibre.When injection molding, material temperature is approximately 100 DEG C to 350 DEG C, and jet pressure is approximately 400 to 1600 bar, and die temperature is approximately 40 DEG C to 160 DEG C.When processing thermoplastic plastics, screw rod is quite warm, so that molten thermoplastic material.In contrast, mould is quite cool, to cool the profiled member just generated.When processing thermosetting plastics, temperature and the stream curing action of plasticization unit
match, therefore usually lower than the temperature when processing thermoplastic plastics, and for injection unit, mould must be held hotter, to enable material solidify at this.
Implement in screw type injection molding machine elastomeric injection molding is preferred equally.Elastomer can be Powdered or in zonally being drawn in by a special screw rod, described screw rod imposes shearing to plastifying material hardly with (rieselfaehig) that can flow.Cylinder regulates temperature with liquid usually, overheated to avoid.Processing temperature is approximately 70 DEG C, to prevent from, in cylinder, vulcanization reaction occurs.Do not consider aforementioned special way, similar with the injection molding process of carrying out thermoplastic on injection molding process principle now.Screw rod carries out kneading to moulding material and mixes, thus by its preprocessing uniformly shape.Such as compared with die pressing, the object of the quantity of sintered parts manufactured by improvement can be reached by said method, because in die pressing, because the heat of outside input can make temperature distributing disproportionation even.And course of working is also carried out relatively fast.Frictional heat can be produced when flowing in jet pipe and casting pipeline.Which reduce as carrying out necessary vulcanization reaction and required time in the elastomer.Therefore, the operation process of injection molding is very economical.Compared with the elastomer be made up of mold pressing, the more elastomeric mechanical propertys made by injection molding can exceed 30%.High viscosity of material requires relatively large runner section.When elastomer injection molding, often for multiple mould and different piece adopt the injection molding machine with multiple linkage unit (Schlie β einheit), because the vulcanization reaction time is obviously longer than the preprocessing time in injection unit.This makes elastomeric injection molding especially economical.
Especially can know thus, if matrix and circumferential seal and/or thread premium device are made up of hetero-polymer material, such as, matrix is made up of thermoplastic, circumferential seal and/or thread premium device are then made up of elastomer, so this manufacture can only realize by multi-part injection molding method easily in a machine, in described multi-part injection molding method, the injection molding step of thermoplastic and the generation one after another of elastomeric injection molding step.
According to the special thread safty device of helical element of the present invention, its salient point being different from known thread premium device is, it is not be made into line, but by multi-part jet moulding, or especially two parts jet mouldings and be manufactured into the parts manufactured together with helical element.Now, for holding the one or more of thread premium device and/or circumferential seal in described helical element, particularly axially and/or the radial groove extended can be shaping without cutting in mode favourable on technics in the injection molding process of described helical element.
Only by unique thread premium device, just can realize the object compensating the screw thread of helical element and the tolerance of another component and improve anti-seismic performance, thus when can effectively prevent the spiral between helical element and another component described to be connected to variable load, occur the situation of unclamping.This is by being achieved at the such clamping action produced by the resiliently deformable of thread premium device when strengthening helical element of screw-in.Now, the gap especially between the outside thread and the internal thread of another component of helical element can by the filling of thread premium device, so thread premium device reaches the object improving surface pressure between thread contour side respect to one another.
The connection of one all can be unclamped at any time although it is so, but even if the reliability that this strengthening connects still must keep after repeatedly screwing in and screwing out.Therefore prevent and automatically occur loosening according to helical element of the present invention is lower in working order and unclamps.
By means of multiple preferred embodiment, the present invention is described in detail below.Wherein:
