Description
Technical field
The present invention relates to a kind of white cast-iron liner plate (Hartguss-Kachel),, particularly give the inwall lining of the mixing channel of concrete mixer in order to give the inwall lining of groove shape container.Described liner plate has one and is used for liner plate is fixed on aperture on the inwall, and the perisporium in the aperture is cast with screw thread.In addition, the invention still further relates to a kind of method that is used to make this white cast-iron liner plate.
Background technology
Adopt such liner plate, protect the place of bearing strong wearing and tearing on the mixing channel inwall by a wear-resisting lining.Usually, this much more wear-resisting that liner plate just is installed at frayed big place on the inwall than general steel plate, rather than on whole inwall.So just can make the inwall wearing and tearing equably basically of mixing channel.In order to reach this purpose, white cast-iron is proved to be to make the suitable material of this liner plate, white cast-iron be a kind of can only be by the hard fragile material of grinding.
According to prior art, for being fixed to, mixes on the cell wall white cast-iron liner plate, an aperture is set in liner plate, one is used for liner plate is fixed to retaining element on the mixing channel inwall, for example a bolt passes this aperture, and this retaining element then is fastened on the inwall by screwing again.Retaining element has the head that a cross section strengthens at its end towards the mixing channel inner face.Correspondingly, the aperture that is formed in the liner plate also is a stairstepping, and its shape with fixation element head is consistent.For this fixed form, especially disadvantageously, in case the termination of retaining element is worn away, this connected mode has not just existed.Yet since the thickness of termination always the thickness than liner plate is little, so liner plate will not fallen down from mixing cell wall before the wearing and tearing as yet fully.
For prolonging the service life of this white cast-iron liner plate, people wish that it can be used its surperficial place as far as possible always or thoroughly worn and torn in many places.In order to reach this purpose, attempt in the following way the white cast-iron liner plate being fixed to and mix on the cell wall: a screwed aperture is set in each white cast-iron liner plate, a retaining element that is fixed on the outer wall is screwed in the screw thread in aperture.Liner plate is abutted on the cell wall always, up to screw thread last, till two ridges are worn away.Yet machining screw is extremely difficult on this white cast-iron liner plate.Consider the rockiness and the fragility of white cast-iron, this material can only carry out grinding, thereby screw thread can not be by mechanical-moulded processing, for example turning or milling, method make, and can only in the casting process of white cast-iron liner plate, produce.
Usually, for fixation workpiece, use the bolt or the nut of the slightly pointed form of thread of tool, for example the profile angle of ISO metric system is the screw thread of 60 degree.The screw bolt and nut that is provided with this retaining thread can tighten member securely mutually.Employing has the sharp thread of little lead angle and big profile angle, can produce bigger frictional force between internal and external screw thread, makes to connect to be difficult to get loose automatically.But this screw thread is not to process by the method for casting usually, but passes through other moulding process on workpiece, for example turning, cutting, drilling or milling.And these moulding process and be not suitable for extremely hard and fragile materials, for example white cast-iron.
Previous trial by the casting method machining screw is proved to be can not be satisfactory.When using ceramic die and core rod to come the moulding screw thread,, a large amount of bubbles that produce in casting process can not reach owing to making for the desired cast(ing) surface systematicness of screw thread and duplicate the moulding accuracy.For the situation of using the quartz sand mould, before casting white cast-iron liner plate, need to give the quartz sand mould to be equipped with a kind of suitable in-mould paint layer (Schlichte), the screw thread of casting must be reprocessed, because it does not reach desired finish.White cast-iron can only be ground processing, and this is a very complicated process, so very uneconomical.
The result of final these trials is that prior art is got back to the sort of solution that the white cast-iron liner plate is fixed on the chamber wall that has just begun to mention again and come.
Summary of the invention
The objective of the invention is to, a kind of white cast-iron liner plate that improved, that be cast with screw thread is provided,, and provide a kind of method that is used to make this white cast-iron liner plate so that be fixed on the groove shape container.
For this reason, the invention provides a kind of white cast-iron liner plate, in order to giving the inwall lining of groove shape container, it has one and is used for liner plate is fixed on aperture on the inwall, and the perisporium in the aperture is cast with screw thread, it is characterized in that, described screw thread is a round thread.
According to the present invention, provided a kind of white cast-iron liner plate of the above-mentioned type, wherein, screw thread is designed to round thread.
The use of round thread is known, particularly in the drive technology field.For example round thread is used for the power transmission shaft of linear transmission, compares with sharp thread, and round thread has less frictional force between internal and external screw thread, thereby moves very light.Because the less and mobile very light characteristics of frictional force of round thread, it is not suitable for a workpiece for good and all is fixed to above the another one workpiece, particularly when this screw thread suffers the load of strong and fluctuation continuously, the vibration that always produces when for example working as concrete mixer.Under the influence of vibration, be threaded and produce the danger that gets loose gradually.Beyond thought is that the round thread of casting but can guarantee liner plate is fixed on the inwall of mixing channel steadily in the long term.
Use round thread can allow internal thread and the external screw thread that is screwed between have relatively large deviation.This greatly facilitates the casting of screw thread.Do not had sharp limit, just meaned that (master mold Negativ-Gussform) wants much simple with the making of foundry goods with respect to the screw thread of other types for model, bed die.The result is that the casting of round thread can be saved the step of a lot of complexity and high cost, particularly reprocesses this step.Thereby might make the white cast-iron liner plate in a kind of efficient and mode competitiveness, it is compared with used white cast-iron liner plate an additional wearing and tearing storage level in addition.
In the method that is used for making the white cast-iron liner plate of the present invention, regulation, that part that is used to construct the aperture in the bed die of liner plate is at least made by zircon sand, and is formed with round thread.The casting method itself of making liner plate according to this can be a kind of method well known in the prior art.It is specially suitable wherein coming the method for casting by the bed die mistake mould that molding sand or ceramic material are made.
Must form a smooth as far as possible surface when making the sharp thread of casting as far as possible, use round thread of the present invention then can accept a much coarse surface.This shows that the requirement for in-mould paint layer significantly reduces.Discover, use the moulding material of zircon sand, even can not want in-mould paint layer fully as bed die.Be that by an important advantage saving the in-mould paint layer acquisition bed die can keep certain gas permeability in the casting process.Like this, gas that when casting liner plate, is released, for example contain in the employed founding materials or the gas of thoroughly from casting mould, discharging can be by casting mould the hole of moulding material overflow.This has just reduced to cause defective risk on the casting liner plate owing to forming bubble (so-called shrinkage cavity) at air-locked relatively mold wash laminar surface.
Discover, if the particle diameter of zircon sand that is used for making bed die is less than 0.2mm, even if do not use in-mould paint layer also can obtain a smooth enough round thread surface.
Description of drawings
By embodiment shown in the drawings the present invention is described in more detail below.Wherein:

The specific embodiment
Fig. 1 shows the cutaway view of a white cast-iron liner plate 10, and this white cast-iron liner plate 10 is particularly given the inwall lining of the mixing channel of concrete mixer in order to give the inwall lining of groove shape container.For white cast-iron liner plate 10 is fixed on the inwall, it is provided with a concentric aperture 12.On the cylindrical wall in aperture 12, be provided with round thread 14.In the white cast-iron liner plate 10 shown in Fig. 1, aperture 12 and round thread 14 have penetrated the whole thickness d of white cast-iron liner plate 10.For the white cast-iron liner plate being fixed on the inwall of mixing channel, for example pierce into a corresponding opening that mixes cell wall from the outside by a bolt that is provided with corresponding round thread, and tighten with liner plate 10, thereby liner plate 10 fits together tightly with the inwall of its back side R and mixing channel.It is desirable to, the bolt that is used to fix has such length, that is, by under the securing situation firmly, the end of bolt flushes with liner plate inwall I at liner plate.Certainly, be different from the structural design among Fig. 1, also it is contemplated that, make aperture 12 only extend the part of liner plate 10 thickness d, that is to say only to form pit, do not form and penetrate from the back side R of liner plate 10.
For white cast-iron liner plate 10 is fixed on the mixing channel inwall, be cast with a round thread on the cylindrical wall in aperture 12.Consider the rockiness and the fragility of white cast-iron, this screw thread in the white cast-iron workpiece unlikely carries out milling, cutting or turning, and must produce in the casting process of white cast-iron liner plate.
Fig. 2 shows a part of cutaway view that is used to cast white cast-iron liner plate shown in Figure 1 in the bed die 20.This part has a concentric projection 22 shown in figure 2, and it is used for forming the aperture 12 in the white cast-iron liner plate 10.This projection protrudes out a length d from the wall 24s of bed die 20, and wall 24 is in order to constitute the back side R of white cast-iron liner plate.The cylindrical side wall of projection 22 is provided with a reverse round thread (Negativ-Rundgewinde) 26, and this reverse round thread is used for forming the round thread on the white cast-iron liner plate 10.
Adopt particle diameter to make bed die 20 as moulding material less than the zircon sand of 0.2mm.Use this moulding material to form smooth enough surface when casting, so that form the round thread that can screw, and bed die needn't be used the mold wash coating before casting.Save the in-mould paint layer of bed die, can remain in the reliability that improves casting method under the situation of permissible range in surface roughness, this is because the gas that discharges when workpiece cast can be by the hole effusion of bed die.
