In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.
The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, with the specific understanding that: both a and B may be included, a may be present alone, or B may be present alone, and any of the three cases can be provided.
Referring to fig. 1-13, the deformation device for the shape memory cylindrical rubber cylinder provided by the present invention comprises a heating cylinder 1, a heating cylinder base 5, a heat medium inlet 2, a heat medium outlet 6, a shaping cylinder 9, a deformation mold 11 and a fixing mechanism for the shape memory cylindrical rubber cylinder 13 to be deformed. The heating cylinder base 5 is fixedly connected to the bottom end of the heating cylinder 1. The bottom end of the shaping cylinder 9 is fixedly connected to the top end of the deforming mold 11 to form a deforming assembly, the deforming assembly is accommodated in the first accommodating space of the heating cylinder 1, and the first accommodating space is divided into a sixth accommodating space 8 and a seventh accommodating space 17 by the deforming mold 11. The second accommodating space 10 of the shaping cylinder 9 is communicated with the third accommodating space 19 of the deformation mold 11 to form a deformation cavity. The heat medium inlet 2 is fixedly connected to the top of the heating cylinder 1, and the heat medium outlet 6 is fixedly connected to the bottom of the heating cylinder 1, so that the top end of the shaping cylinder 9 is higher than the top end of the heat medium inlet 2, or the top end of the shaping cylinder 9 is flush with the top end of the heat medium inlet 2. After being fixed by the fixing mechanism, the to-be-deformed shape memory columnar rubber cylinder 13 can pass through the deformation cavity, and the inner diameter of the second accommodating space 10 is equal to the target diameter of the to-be-deformed shape memory columnar rubber cylinder. In this embodiment, the positions of the heat medium inlet 2 and the heat medium outlet 6 can be interchanged. The heat medium used is generally a heat medium with a high boiling point, and since the boiling point of water is 100 ℃ at 1 atm, the temperature of water does not increase further once it boils, but 100 ℃ at 1 atm is not enough to cause deformation of the shape memory material. Thus, in general, it is desirable to employ a high boiling point thermal medium, for example, linseed oil having a boiling point of 287 deg.C, edible oils having a boiling point of about 250 deg.C, liquid naphthalene having a boiling point of 218 deg.C, kerosene having a boiling point of 150 deg.C, by way of example and not by way of limitation. In practice, the heat medium may be selected according to the material of the shape memory columnar colloid to be deformed.
In the application process of the deformation device for the shape memory cylindrical rubber cylinder provided by the embodiment of the utility model, the deformation component is fixed into the first accommodating space of the heating cylinder 1 from the top of the heating cylinder 1, wherein the first accommodating space is divided into a sixth accommodating space 8 and a seventh accommodating space 17 by the deformation mold 11; after the shape memory cylindrical rubber cylinder 13 to be deformed is fixed by the fixing mechanism of the shape memory cylindrical rubber cylinder 13 to be deformed, the shape memory cylindrical rubber cylinder 13 to be deformed firstly enters the seventh accommodating space 17 from the bottom of the heating cylinder 1, and gradually enters the deformation cavity along with the increase of the entering depth of the fixed shape memory cylindrical rubber cylinder 13 to be deformed in the seventh accommodating space 17. Then, a heat medium is injected into the first accommodating space through the heat medium inlet 2, and the interiors of the sixth accommodating space 8 and the seventh accommodating space 17 are filled with the heat medium, so that the heat medium can heat the shape memory cylindrical rubber sleeve 13 to be deformed and the shape memory cylindrical rubber sleeve in the deformation process. Thereafter, a drawing force is applied to the fixing mechanism of the shape memory cylindrical rubber sleeve 13 to be deformed in the axial direction of the shaping sleeve 9, and then, since the inner diameter of the second accommodating space 10 is equal to the target diameter of the shape memory cylindrical rubber sleeve 13 to be deformed, in the process of moving upwards in the axial direction of the second accommodating space 10 through the shape memory cylindrical rubber sleeve 13 to be deformed after fixing, the shape memory cylindrical rubber sleeve 13 to be deformed is deformed to the target diameter under the limiting action of the shaping sleeve 9. Therefore, the embodiment of the utility model provides a structure of shape memory column packing element constitutes simply, and the theory of operation is easily understood, the low in cost of each component part, and consequently, it can enough realize treating the deformation of shape memory column packing element 13, and the cost is also lower relatively.
In this embodiment, the shaping cylinder 9 is made of a heat conductive material, i.e., a material with a high heat conductivity coefficient, such as iron, stainless steel, and hard alloy, in this case, it is not only convenient for the heat medium to heat the shape memory cylindrical rubber cylinder during the deformation process, but also difficult to deform the shape memory cylindrical rubber cylinder 13 to the target diameter due to the deformation of the shaping cylinder 9 itself caused by the application of the drawing force. The heating cylinder 5 is made of heat-insulating materials, namely materials with low heat conductivity coefficient, such as hard plastic PVC and hardwood, or the heating cylinder 5 is of a double-layer structure, and heat-insulating materials such as rock wool are filled in the cavity, under the condition, the heat of the heat medium in the first accommodating space is mainly conducted to the shape memory cylindrical rubber cylinder in the deformation process through the shaping cylinder 9 and is less dissipated through the heating cylinder 1, so that the heat energy can be better utilized, and the heat energy is saved.
The bottom inner diameter of the third accommodating space 19 is larger than the maximum diameter of the shape memory cylindrical rubber cylinder 13 to be deformed. In this case, the shape memory cylindrical rubber sleeve 13 to be deformed can be easily and smoothly entered into the third accommodating space 19, and the shape memory cylindrical rubber sleeve is not difficult to enter into the deformation cavity due to interference of the bottom end of the deformation mold 11 in the process of entering into the third accommodating space 19. The top inner diameter of the third accommodating space 19 is equal to the inner diameter of the sizing cylinder 9. In this case, after the deformation mold 11 is fixedly connected with the shaping cylinder 9, the continuity of the deformation cavity formed between the second accommodating space 10 and the third accommodating space 19 after the connection can be ensured, so as to facilitate the smooth passage of the shape memory cylindrical rubber cylinder 13 to be deformed. In this embodiment, the bottom nozzle of the sizing cylinder 9 is provided with the first flange plate 22, the top nozzle of the deformation mold 11 is provided with the second flange plate 21, and after the first flange plate 22 and the second flange plate 21 are fixedly connected together by the fastening bolt, the second accommodating space 10 and the third accommodating space 19 can be communicated to form a continuous deformation cavity, so that the clamping stagnation at the joint of the sizing cylinder 9 and the deformation mold 11 in the process of axially penetrating the sizing cylinder 9 by the shape memory columnar packing element 13 to be deformed can be avoided. The inner diameter of the third accommodating space 19 gradually decreases from the bottom end of the third accommodating space 19 to the top end of the third accommodating space 19. In this case, the diameter of the to-be-deformed shape memory cylindrical rubber sleeve 13 can be gradually reduced in the diameter reducing process, so that the diameter reducing process of the to-be-deformed shape memory cylindrical rubber sleeve 13 is ensured to be smoother.
The fixing mechanism of the shape memory cylindrical rubber cylinder 13 to be deformed comprises a base pipe 12, a traction mechanism and a binding piece 35. The shape memory cylindrical rubber sleeve 13 to be deformed is formed on the periphery of the base pipe 12, and the binding piece 35 binds the shape memory cylindrical rubber sleeve 13 to be deformed on the periphery of the base pipe 12 at the top of the base pipe 12. In this case, the shape memory cylindrical rubber tube 13 to be deformed is fixed inside by the base tube 12, so that the false deformation caused by centripetal contraction of the shape memory cylindrical rubber tube 13 to be deformed in the deformation process can be avoided. The introduction of the binding member 35 can prevent the shape memory cylindrical rubber tube 13 to be deformed from falling off downwards along the axial direction of the base tube 12 due to the formation of a sliding pair between the base tube 12 and the base tube 12 after the drawing force is applied. In this embodiment, the binding member 35 is made of a crosslinked or uncrosslinked rubber tube, a telescopic net tube, a fabric net, etc., and is wound and fixed on the top of the shape memory cylindrical rubber tube 13 to be deformed and the base tube 12. The binding piece 35 after binding can be in clearance fit with the inner wall of the shaping cylinder 9. In this case, since the bundled binding member 35 itself also has a thickness, the bundled binding member 35 can be in clearance fit with the inner wall of the shaping barrel 9, so that the bundled binding member 35 can be prevented from generating a friction force with the inner wall of the shaping barrel 9 in the process of upward movement under a drawing force to interfere with the upward movement of the shape memory cylindrical rubber barrel 13 to be deformed. The pulling mechanism is fixedly attached to the top end of the base pipe 12 such that the pulling head 26 of the pulling mechanism is exposed from the top of the base pipe 12. In this case, since the pulling head 26 of the pulling mechanism is exposed from the top of the base pipe 12, the connection between the force applying mechanism and the shape memory cylindrical rubber tube 13 to be deformed is facilitated when the pulling force is applied.
The pulling mechanism comprises a plug 31, a pressing plate 28 and a pulling plate 23. The stopper 31 comprises a side wall 33 and a partition 32, the side wall 33 is cylindrical, and the partition 32 is fixedly connected to the side wall 33. The inner cavity of the plug 31 is divided into a fourth receiving space 39 and a fifth receiving space 40 by the partition 32. A first through hole 41 is formed in the center of the partition plate 32, and a sliding pair is formed between the outer wall of the choke plug 31 and the inner wall of the shaping cylinder 9; here, since the plug 31 forms a sliding pair with the inner wall of the setting cylinder 9 through the outer wall thereof, that is, the outer diameter of the plug 31 and the inner diameter of the setting cylinder 9 are matched with each other, in this case, since the side wall 33 of the plug 31 has a length in the axial direction, it also has a guiding function, that is, it is possible to prevent the shape-memory cylindrical rubber cylinder 13 to be deformed from being stuck due to deflection during the upward movement in the axial direction of the setting cylinder 9 under the pulling force. In some cases, in order to further ensure that the to-be-deformed shape memory cylindrical rubber sleeve 13 is stably connected to the outer periphery of the base pipe 12 and does not fall off from the base pipe 12 in the process of moving upward along the axial direction of the shaping cylinder 9, when the to-be-deformed shape memory cylindrical rubber sleeve 13 is formed on the outer periphery of the base pipe 12, the to-be-deformed shape memory cylindrical rubber sleeve can be simultaneously wrapped on the outer wall of the plug 31, and at this time, a sliding pair needs to be formed between the outer wall of the to-be-deformed shape memory cylindrical rubber sleeve 13 formed on the outer periphery of the plug 31 and the inner wall of the shaping cylinder 9. The pressing plate 28 includes a body 29, a shoulder 30 is formed on the top of the body 29, and a second through hole 38 is opened at the center of the pressing plate 28. The body 29 is accommodated in the fourth accommodating space 39, such that the first through hole 41 and the second through hole 38 are communicated to form a through hole. In this case, in order to ensure the connection stability of the pressing plate 28 and the plug 31, a plurality of first connection holes 39 may be axially formed in the radial cross section of the pressing plate 28, and, at the same time, a plurality of second connection holes 43 may be formed in the partition plate 32 of the plug 31, wherein the plurality of first connection holes 39 correspond one-to-one to the plurality of second connection holes 43, and in this case, the respective locking bolts can be simultaneously inserted into the first coupling hole 39 and the second coupling hole 43, so that the pressing plate 28 is connected with the plug 31, in the embodiment, the plurality of first connecting holes 39 are uniformly distributed on the radial section of the pressing plate 28, the plurality of second connecting holes 43 are uniformly distributed on the partition plate 32, in this case, since the connection points between the pressing plate 28 and the partition plate 32 are uniformly distributed, the connection force between the pressing plate 28 and the plug 31 is uniformly distributed, and the connection stability between the pressing plate 28 and the plug 31 can be ensured. The plug 31 can be fixedly connected to the top end of the base pipe 12 through the sidewall of the fifth receiving space 40. In this case, the thickness of the top end cap of the substrate tube 12, which is formed by connecting the partition plate 32 and the pressure plate 28 together, is large, and the substrate tube receives the pulling force and has a stronger ability to receive the reaction force, so that smooth transfer of the pulling force can be ensured. The pulling plate 23 comprises a head 24, a neck 25 and a drawing head 26, wherein the head 24, the neck 25 and the drawing head 26 are fixedly connected in sequence, and in the embodiment, the head 24, the neck 25 and the drawing head 26 which are the components of the pulling plate 23 are integrally formed, in this case, the service life of the pulling plate can be prolonged because the connecting joints do not exist among the pulling plate, the neck 25 and the drawing head 26. The diameter of the head 24 is larger than that of the through hole, in this case, when the pulling plate 23 bears the pulling force through the pulling head 26, due to the blocking relation between the head 24 and the partition plate 32, the pulling plate 23 can be prevented from being pulled out upwards through the through hole to cause an operation accident. Neck 25 can with wear to establish the hole clearance fit, under this condition, penetrate the in-process to wearing to establish the hole with arm-tie 23, can avoid taking place to interfere and be difficult to pass this wearing to establish the hole between neck 25 and the lateral wall of wearing to establish the hole. So that the traction head 26 can emerge from the top of the shoulder 30. In this case, when the pulling force is applied to the shape memory cylindrical rubber sleeve 13 to be deformed, only the force application mechanism of the pulling force needs to be fixedly connected with the traction head 26, and the connection process is simple and convenient.
Wherein the drawing head 26 is provided with drawing holes 27 in the radial direction. In this case, the pulling force along the axial direction of the shaping cylinder 9 can be applied to the cylindrical rubber cylinder 13 with shape memory to be deformed only by tying the force application mechanism of the pulling force on the traction hole 27 through a mechanism similar to a thread rope, and the connection is simple and convenient. In practice, after the shape memory columnar colloid 13 to be deformed, the shaping cylinder 9 and the deformation mold 11 are assembled, the pulling plate 23 connected with the cord is lifted out of the through hole, and finally, the other end of the cord is connected with the force application mechanism, wherein the force application mechanism can be omitted, and the pulling force can be applied to the pulling plate 23 by hand, so that the diameter reduction operation of the shape memory columnar colloid 13 to be deformed in the process of moving upwards along the axial direction of the shaping cylinder 9 can be completed.
Wherein, the inner wall of the fifth accommodating space 40 is provided with an internal thread, the top end of the base tube 12 is provided with an external thread, and the internal thread is matched with the external thread. In this case, plug 31 can be removably coupled to base pipe 12, which can facilitate replacement of plug 31 and pressure plate 28. In addition, the plug 31 can be detachably connected with the base pipe 12 in a snap-fit manner. If the base pipe 12 is detachably connected with the plug 31, the base pipe 12 and the plug 31 can be fixedly connected together by welding or integrally forming.
Wherein, the top of the shaping cylinder 9 forms a disc-shaped area 16, and the outer diameter of the disc-shaped area 16 is larger than that of the shaping cylinder 9, so that the bottom of the disc-shaped area 16 is annular. The embodiment of the utility model provides an among the deformation device of shape memory column packing element, the bottom of a design section of thick bamboo 9 is in the same place through first ring flange 22 and second ring flange 21 fixed connection with the top of deformation mould 11, can't accomplish sealing connection. In addition, the binding 35, the side wall 33 of the plug 31 or the material of the to-be-deformed shape-memory cylindrical rubber tube 13 formed outside the side wall 33 of the plug 31 cannot be matched with the inner wall of the shaping tube 9 for sealing connection. Therefore, a part of the heat medium enters the second accommodating space 10 of the shaping cylinder 9 from the connecting joint between the first flange 22 and the second flange 21, the binding piece 35, the side wall 33 of the plug 31 or the gap between the material of the shape memory cylindrical rubber cylinder 13 to be deformed formed outside the side wall 33 of the plug 31 and the inner wall of the shaping cylinder 9, but along with the upward movement of the shape memory cylindrical rubber cylinder 13 in the deformation process along the axial direction of the shaping cylinder 9, the deformed shape memory cylindrical rubber cylinder 13 blocks the joint and the gap, so that the heat medium is prevented from further entering the second accommodating space 10, that is, the heat medium entering the second accommodating space 10 is only a small amount. In this case, as the shape memory cylindrical rubber sleeve 13 in the deformation process moves upward along the axial direction of the shaping sleeve 9, the heat medium in the second accommodating space 10 can be lifted to the top of the shaping sleeve 9, in this case, since the outer diameter of the disc-shaped area 16 is larger than that of the shaping sleeve 9, the disc-shaped area 16 can accommodate more heat medium, so as to avoid the heat medium entering the second accommodating space 10 from being gushed out and causing waste of the heat medium in the process that the shape memory cylindrical rubber sleeve 13 to be deformed is pulled upward along the shaping sleeve 9. In this embodiment, the top of the heating cylinder 1 is provided with the third flange 3, the top of the disc-shaped area 16 is provided with the fourth flange 4, and the top of the shaping cylinder 9 can be fixedly connected to the top of the heating cylinder 1 through the connection between the third flange 3 and the fourth flange 4. In order to ensure the centring of the shaped cylinder 9 on the top of the heating cylinder 1, it is also possible to make the outer diameter of the disk-shaped zone 16 equal to the inner diameter of the heating cylinder 1.
Wherein, the bottom of the disc-shaped area 16 is provided with a plurality of overflow holes 42, so that the disc-shaped area 16 is communicated with the first accommodating space through the overflow holes 42. In this case, the heat medium collected by the disk area 16 can continuously flow back into the first accommodating space of the heating cartridge 1 through the overflow holes 42, and therefore, the utilization rate of the heat medium can be further improved.
Wherein, the maximum outer diameter of the deformation die 11 is in clearance fit with the side wall of the heating cylinder 1. In this case, it is possible to achieve the centring of the deformation die 11 inside the heating cylinder 1, so as to avoid the deviation of the shaped cylinder 9 from the vertical, which affects the application of the drawing force. It is also possible to prevent the heat medium from being unevenly distributed in the first accommodating space of the heating cartridge 1 due to the complete separation between the sixth accommodating space 8 and the seventh accommodating space 17 caused by the shape of the deforming mold 11.
The maximum outer diameter of the deforming mold 11 is columnar, and the columnar surface is provided with a groove 18 and a protrusion 36, and the diameter of the protrusion 36 is equal to the inner diameter of the heating cylinder 1. In this case, since the diameter of the protrusion 36 is equal to the inner diameter of the heating cylinder 1, the deflection of the sizing cylinder 9 in the vertical direction can be substantially completely avoided, that is, the centering performance of the sizing cylinder 9 can be made more perfect. The groove 18 can prevent the heat medium from being distributed in the first accommodating space of the heating cylinder 1 due to the complete separation between the sixth accommodating space 8 and the seventh accommodating space 17 caused by the shape of the deforming mold 11.
Furthermore, in the present embodiment:
the heating cartridge 1 can be detachably and fixedly connected to the outside through the heating cartridge base 5, for example, a plurality of threaded holes may be provided on the heating cartridge base 5, and the heating cartridge base 5 can be detachably and fixedly connected to the outside through bolts. In order to guarantee the joint strength of heating cylinder base 5 external connection, can also set up a plurality of reinforcing plates 7 between the lateral wall of heating cylinder 1 and heating cylinder base 5, these a plurality of reinforcing plates 7 can be right triangle, a right-angle side fixed connection of this right triangle in heating cylinder base 5, another right-angle side fixed connection in the lateral wall of heating cylinder 1 to utilize triangle-shaped stable structure, guarantee at the in-process of exerting the drawing force, heating cylinder 1 does not incline.
An annular groove 46 is arranged at the barrel mouth of the top end 20 of the deformation die 11, and the radial dimension of the annular groove 46 is the same as the wall thickness of the shaping barrel 9, so that when the deformation die 11 is connected with the shaping barrel 9, the shaping barrel 9 can be inserted into the barrel mouth of the top end 20 of the deformation die 11 through the side wall of the shaping barrel 9, and the connection centering performance of the shaping barrel 9 and the deformation die 11 is ensured.
The bottom end 44 and the top end 20 of the deformation die 11 are rounded at the outer transition zone 45, in which case stress concentrations under the drawing force can be avoided, thereby increasing the service life of the deformation die 11.
It should be further explained that the embodiments of the present invention provide a shape memory column rubber cylinder deforming apparatus, in which each component is processed with a chamfer or a fillet, so as to facilitate assembly or reduce wear.
