Abstract
A tubular cavity block is used when making a plastic tube through centrifugal casting. The invention provides a settlement proposal which is simple in structure, low in price and reliable in work. The settlement relates to that: the driving end of the cavity block is provided with a pivot bearing whose position is fixed and the other end of the cavity block, usually the discharging end, is provided with a bearing(3) which can move along the axis. The mobility is realized through the following proposal: an outer bearing ring(3b) usually made of steel is fixed on two gap blocks(12d) which are best to be made of bronze; each gap block is provided with two side clamp cheeks(12f,12g) and the outer bearing ring(3b) can move to-and-fro between the two side clamp cheeks along the axis.
Description
The present invention relates to a kind ofly adopt centrifugal casting process to manufacture at least 6 meters long, diameter to be at least 150 millimeters, the equipment of fiber and steel bar reinforced plastic tube.The tubulose former that this equipment has is a horizontal axis, motor-driven, have a feed end and a discharge end, each end of this former with one by outer shroud, interior ring and the interior ring that is arranged on the rolling bearing that the rolling element between the above two constitutes is fixedlyed connected and its at feed end by motor-driven.
Because during manufacturing, the plastic hardening temperature is changing, the temperature of former and length thereof also can change.In order to realize this length variations, the position of the bearing of feed end is fixed in equipment of the present invention, but but another bearing is translation in the axial direction.For the unlikely fault that causes in the process of manufacturing of the variation that makes former length, structure is complicated, corresponding costliness and bearing that be subject to disturb so must adopt in this known equipment.
The present invention proposes a kind of simple project organization, can adopt expensive special bearing in this project organization, this point is extremely important, and this is because if will manufacture the pipe fitting with different-diameter the time, verified, the transposing former is suitable or necessary.So the design of bearing should make it unlikely the transposing former be caused difficulty, but is convenient to the transposing of former.These two conditions are met by following equipment:
In two outer shrouds each all is installed on two bearing blocks,
Each bearing block have a bearing shell that has supporting plate and two lateral cheeks wherein the spacing between the lateral cheek of each bearing shell of the bearing of charging end equate with the axial length of outer shroud, but in another bearing the cheek spacing because measuring of may expanding of former and annulate shaft is long in addition wants big this swell increment.
The outer shroud of each bearing has at least two axial bolts, and this bolt lays respectively in the opening of lateral cheek and therefore prevents the outer shroud rotation.
To contrast accompanying drawing below embodiments of the invention will be done an explanation.Shown in sketch:
The side view of Fig. 1 present device,
Fig. 2 and 3 rolling bearing front views, exactly,
The front view of Fig. 2 feed end and
The front view of Fig. 3 discharge end,
Figure 4 and 5 rolling bearing outer shroud profile, exactly,
The profile of Fig. 4 feed end and
The profile of Fig. 5 discharge end.
Indicate the tubulose former with 1 in the drawings, at least 6 meters long of this formers and its internal diameter are at least 150 millimeters.This former is used to adopt the production of the fiber and steel bar reinforced plastic tube that centrifugal casting process manufactures.For this reason, this former is bearing on two gantry posts 2 and 3, and this gantry post is made of ring 2a or 3a, an outer shroud 2b or a 3b in one and the ball 5 that is arranged between the above two respectively.Have a flange 1a on each end of tubulose former 1, one interior ring in two ball bearings is screwed respectively on this flange, and exactly, the left side feed end in Fig. 1 is the interior ring 2a of bearing 2; At opposite side is the interior ring 3a of bearing 3.Among two outer shroud 2b and the 3b each all has two packing rings 14, though this packing ring can make two rings rotation mutually of bearing, can stop its mutual axial translation, and this is identical with common situation in the rolling bearing.Be screwed another ring 6 in being all on the side of ring 2a and former 1 wall, this ring is connected with the driving wheel 4a of drive motors 4 by V belt 7.Not shown charge mechanism adopts this charge mechanism can be from drive end, promptly charging end add be used for tubulation such as raw materials such as the liquid resin that can add filler, sand and fibrous materials.Put down in writing this charge mechanism at WO93/008009.
Can clearly be seen that from Fig. 2 and 4 the outer shroud 2b of bearing 2 is fixed on two bearing blocks 9 and 10.These two bearing block structures are identical, but are as the criterion symmetrically with a vertical median plane.Each bearing block has a substrate 9a, a support 9b and a bearing shell 9d.Substrate 9a removably is fixed on the pedestal 11 and with support 9b with screw and links together non-dismountablely, and support has one by the suitable head portion 9c that makes of steel, and the bearing shell 9d that is made by bronze immovably but removably be fixed on this support.This bearing shell 9d has a supporting plate 9e and two lateral cheek 9f and 9g, and wherein the spacing of lateral cheek equals the axial length x of outer shroud 2b.This outer shroud 2b has at least two axial bolt 2c and 2d, for having a upwards open opening 9h or a 9i on two lateral cheek 9f of the bearing block of these two axial bolts at least two bearing blocks and each piece among the 9g.Adopt this very simple mode itself, though outer shroud 2b prevents rotation on the one hand, when the pipe 1 that needs to change as former, the dismantlement work that does not need to add can upwards be taken off outer shroud from two bearing blocks but then.
The setting of the outer shroud 3b of the bearing 3 that preferably is formed from steel basically with the outer shroud 2b of above-mentioned bearing 2 that explanation is set is identical, promptly be arranged on the bearing blocks with 12 and 13 signs.It is unique, but also be that important difference is, as from Fig. 5, being well understood to, at each bearing block (12,13) on, the two lateral cheek 12f of bearing shell 12d and the spacing Y between 12g want measuring of the possible axial expansion of the big former of the axial length x of this outer shroud 3b 1 at least.This outer shroud also has at least two, the bolt that indicates with 3c or 3d respectively here, this bolt is positioned at corresponding transverse groove or opening 12h or the 12i of lateral cheek 12f or 12g, thereby though outer shroud 3b can be axially moved and can be on bearing shell 12d by taking out in the bearing shell, bearing shell rotates relatively.
Adopt this type and mode, the former 1 of tubulose can change its length without a doubt when heating and cooling, and can not produce because the danger that machinery or thermal stress break down in operation process.
When changing former as mentioned above, promptly substitute with the former of another diameter, at this moment this another former has two rolling bearings equally, its external diameter can be consistent with the external diameter of the bearing of being changed, but needn't unanimity can not.For not simultaneously at bearing diameter, neither need to change charge mechanism, do not need to change different auxiliary bodies yet, for example water injector can realize that the rotating shaft of the former of all employings is positioned at sustained height all the time by the transposing bearing block.Although because variations in temperature produces the former length variations that can not be ignored, adopt above-mentioned project organization also can use commercial, cheap and firm gantry post.
