Description

Technical Field

[0001] This application relates to the field of molding equipment technology, specifically to a molding apparatus. Background Technology

[0002] Currently, when forming product structural features (such as swirl grooves, tapered necks, and flared necks) through rotary extrusion molding, the product is typically supported by a roller assembly fixedly mounted on a chuck, and the structural features are extruded by a forming assembly also fixedly mounted on the chuck. However, due to the difficulty in adjusting the mounting positions of the roller assembly and forming assembly on the chuck, installation tolerances exist during the installation process, resulting in poor precision of the structural features of the molded product and making the product prone to deformation under the extrusion force of the forming assembly. Utility Model Content

[0003] In view of the above, it is necessary to propose a molding device to improve the accuracy of the structural features of the molded product and reduce the probability of product deformation.

[0004] This application provides a forming apparatus, including: a clamping mechanism comprising a chuck body and at least three jaws connected to the chuck body, the chuck body being used to drive the jaws to move closer or further apart; extrusion members, each corresponding to one of the jaws, each extrusion member being movably disposed on its corresponding jaw; a fixing member disposed between the plurality of extrusion members, the fixing member having a receiving hole at its center and sliding holes on its peripheral sidewalls for cooperating with each extrusion member, each sliding hole extending radially along the fixing member and having its two ends communicating with the peripheral sidewall of the fixing member and the receiving hole, respectively; and an inner support member rotatably... The product is inserted into and supported by the receiving hole; a movable component, corresponding to each of the sliding holes, each movable component including a slider and an elastic component, wherein the slider is slidably disposed in the corresponding sliding hole under the drive of the corresponding extrusion component, and the two ends of the elastic component are respectively connected to the slider and the fixing component; a molding component, rotatably disposed at the end of the slider of one of the movable components facing the receiving hole, for extruding and molding the structural features required for the product; and a plurality of support wheels, rotatably disposed at the ends of the sliders of the remaining movable components facing the receiving holes, for supporting the product from the outside.

[0005] In some embodiments, the sliding member has a mounting hole, a limiting hole, and a plug-in hole. The mounting hole extends along the sliding direction of the sliding member. The plug-in hole is spaced apart from the limiting hole and is connected to the mounting hole. The limiting hole is an oblong hole, and the width direction of the limiting hole is the same as the sliding direction of the sliding member. Each moving component also includes a limiting member and a stop member. The limiting member is inserted into the limiting hole and connected to the fixing member. The stop member is inserted into the plug-in hole. The mounting hole contains an elastic member. The two ends of the elastic member are connected to the stop member and the limiting member, respectively. The elastic member is connected to the sliding member through the stop member and to the fixing member through the limiting member.

[0006] In some embodiments, the molded part includes a wheel body and an annular extrusion part. The wheel body is rotatably disposed at one end of the corresponding slider facing the receiving hole. The annular extrusion part is sleeved on the wheel body and protrudes from the peripheral sidewall of the wheel body. The annular extrusion part is used to extrude and mold the structural features required for the product.

[0007] In some embodiments, the number of the claws, the pressing member, and the moving component are all three, and the three claws are evenly arranged around the axis of the fixing member.

[0008] In some embodiments, the forming apparatus further includes an adapter connected to the side of the chuck body facing the fixing member, the fixing member being disposed on the adapter, the adapter having a plurality of clearance notches, each clearance notch corresponding to each of the extrusion members, each clearance notch extending from the peripheral sidewall of the adapter toward the axis of the fixing member, and each extrusion member being movably disposed within the corresponding clearance notch.

[0009] In some embodiments, each of the extrusion members is provided with an elongated through hole, the width direction of which is the same as the moving direction of the corresponding jaw; the forming device further includes a plurality of connecting members, each of which corresponds to each of the extrusion members, and each of the connecting members passes through the corresponding elongated through hole and is connected to the corresponding jaw.

[0010] In some embodiments, the plurality of sliding holes are located on a plane perpendicular to the axis of the fixing member.

[0011] In some embodiments, each of the extruders has an extrusion groove on the side facing the corresponding slider, and the slider extends into the corresponding extrusion groove.

[0012] In some embodiments, the inner support member is connected to the inner wall of the receiving hole via a bearing sleeved on the inner support member.

[0013] In some embodiments, the end of the inner support member away from the chuck body has a tapered portion.

[0014] When the molding apparatus of this application extrudes and molds the structural features of a product, since the sliding member abuts against the corresponding extruder, and the extruder is movably disposed on the corresponding jaw, if the tolerance of the support wheel and the molding member when extruding the product exceeds the preset range, the position of the extruder on the corresponding jaw can be adjusted, and the tolerance of the support wheel and the molding member when extruding the product can be adjusted accordingly. This improves the concentricity of the structural feature and the product, ensuring that the outer diameter of the structural feature is within the design range, and reducing the probability of the product deforming under the extrusion action of the molding member. Furthermore, since the inner support member is rotatably disposed in the receiving hole and supports the product from the inside, the probability of the support wheel and the molding member deforming the product by extrusion is reduced, as is the probability of the product rotating with the fixed member, thereby improving the accuracy of the structural features of the product extruded and molded by the molding member. Thus, the molding apparatus of this application improves the accuracy of the structural features of the molded product and reduces the probability of product deformation. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0024] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0025] Please see Figure 1 and Figure 2This application provides a forming apparatus 100 for forming structural feature 910 of a product 900. The product 900 can be a medical ultrasonic sleeve, connecting tube, etc., and can be made of ductile materials such as stainless steel or aluminum alloy. Structural feature 910 can be a swirl groove, a tapered constriction, a flared flare, etc. For ease of understanding, this application uses a medical ultrasonic sleeve made of stainless steel as an example, with swirl groove as the structural feature 910, as an example for illustration. Obviously, this is not a limitation of the embodiments of this application.

[0026] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the molding device 100 includes a clamping mechanism 10, a plurality of extrusion parts 20, a fixing part 40, a plurality of moving components 50, an inner support part 61, a plurality of support wheels 71, and a molding part 72.

[0027] The clamping mechanism 10 includes a chuck body 11 and at least three jaws 12 connected to the chuck body 11. The chuck body 11 is used to drive the jaws 12 to move closer or further apart from each other.

[0028] Each extrusion member 20 corresponds to one of each jaw 12, that is, multiple extrusion members 20 correspond to at least three jaws 12, and each extrusion member 20 can be movably disposed on the corresponding jaw 12.

[0029] The fastener 40 is disposed between multiple extrusion parts 20. A receiving hole 41 is provided at the center of the fastener 40. A sliding hole 42 is provided on the peripheral sidewall of the fastener 40 to cooperate with each extrusion part 20. The receiving hole 41 is coaxial with the fastener 40 along the axis L. Each sliding hole 42 extends radially along the fastener 40, and both ends of the sliding hole 42 are connected to the peripheral sidewall of the fastener 40 and the receiving hole 41, respectively.

[0030] The inner support member 61 is rotatably disposed in the storage hole 41. The inner support member 61 is used to insert and support the product 900. The inner support member 61 is adapted to support the product 900.

[0031] Each movable component 50 corresponds one-to-one with each sliding hole 42, meaning that multiple movable components 50 correspond one-to-one with multiple sliding holes 42. Each movable component 50 includes a slider 51 and an elastic member 52. The slider 51 is slidably disposed in the corresponding sliding hole 42 under the action of the corresponding pressing member 20. The two ends of the elastic member 52 are respectively connected to the slider 51 and the fixing member 40. The elastic member 52 is used to move the slider 51 away from the receiving hole 41.

[0032] The molded part 72 is rotatably disposed at one end of the slider 51 of one of the moving components 50 toward the receiving hole 41. The molded part 72 is used for the structural feature 910 required for extruding the product 900.

[0033] Multiple support wheels 71 rotate on the end of the slider 51 of the remaining moving components 50 facing the receiving hole 41, and the multiple support wheels 71 are used to support the product 900 from the outside.

[0034] When the molding apparatus 100 of this application is used to mold the structural feature 910 of the product 900, the product 900 is first inserted into the receiving hole 41 and sleeved on the inner support member 61. The product 900 is fixed by the fixing mechanism (not shown). Then, the chuck body 11 drives the jaws 12 to move closer to each other. Each jaw 12 drives the corresponding extruder 20 to extrude the corresponding sliding member 51. The multiple sliding members 51 move toward the receiving hole 41, the multiple elastic members 52 are compressed, and the multiple support wheels 71 abut against the outer wall of the product 900 under the drive of the corresponding sliding members 51. The molding member 72 abuts against the outer wall of the product 900 under the drive of the corresponding sliding members 51. Then, the molding apparatus 100 rotates under the drive of the rotation drive member (not shown). The inner support member 61 supports the product 900 from the inside, the multiple support wheels 71 support the product 900 from the outside, and the molding member 72 extrudes and molds the structural feature 910 of the product 900.

[0035] Since the sliding member 51 in this embodiment abuts against the corresponding extruder 20, and the extruder 20 is movably disposed on the corresponding claw 12, when the tolerance of the support wheel 71 and the forming member 72 when extruding the product 900 exceeds the preset range, the position of the extruder 20 on the corresponding claw 12 can be adjusted, and the tolerance of the support wheel 71 and the forming member 72 when extruding the product 900 can be adjusted accordingly. This improves the concentricity of the structural feature 910 and the product 900, ensures that the outer diameter of the structural feature 910 is within the design range, and reduces the probability of the product 900 deforming under the extrusion action of the forming member 72. Furthermore, by providing an inner support member 61 to support the product 900 from the inside, the probability of the product 900 being deformed by the support wheel 71 and the molding part 72 is reduced. By rotatably mounting the inner support member 61 in the receiving hole 41, the inner support member 61 can move with the product 900, reducing the friction between the inner support member 61 and the inside of the product 900, and further reducing the probability of the product 900 rotating with the fixing member 40. This improves the precision of the structural feature 910 of the product 900 extruded by the molding part 72. Thus, the molding apparatus 100 of this embodiment improves the precision of the structural feature 910 of the molded product 900 and reduces the probability of deformation of the product 900.

[0036] In this embodiment, the elastic element 52 can be a spring. After the molding device 100 extrudes and molds the structural feature 910 of the product 900, the chuck body 11 drives the multiple jaws 12 to move away from each other, the multiple elastic elements 52 elastically reset, and the elastic elements 52 drive the corresponding sliding elements 51 away from the receiving hole 41. The multiple support wheels 71 and the molding element 72 disengage from the product 900 under the action of the corresponding sliding elements 51, thereby facilitating the removal of the molded product 900.

[0037] In other embodiments, the elastic element 52 may also be a leaf spring, a sheet spring, etc., and this application does not specifically limit it.

[0038] In this embodiment, the structural feature 910 of the extruded product 900 is one. Of course, in some other embodiments, by reasonably setting the structure of the molding part 72, the molding part 72 can also extrude and mold multiple structural features 910 of the product 900 simultaneously. This application embodiment does not specifically limit this.

[0039] In this embodiment, there are three claws 12, three pressing members 20, and three moving components 50. The three claws 12 are evenly arranged with the axis L of the fixing member 40 as the center.

[0040] Specifically, when there are three claws 12, three extruders 20, and three moving components 50, there are also three sliding holes 42, two support wheels 71, and one forming component 72.

[0041] Since the three claws 12 are evenly arranged around the axis L of the fixing member 40, the two support wheels 71 and the forming member 72 are more stable and the force is more even when they are pressing the product 900 under the drive of the corresponding extrusion member 20. This further improves the accuracy of the structural feature 910 of the product 900 formed by the forming device 100 and reduces the probability of deformation of the product 900.

[0042] In other embodiments, the number of claws 12, clamping members 20 and moving components 50 may be four, five, six, etc., if the installation space allows. This application does not specifically limit this.

[0043] In this embodiment, when there are three jaws 12, the clamping mechanism 10 is a three-jaw chuck, and the chuck body 11 can drive the three jaws 12 to move by pneumatic, electric, manual or other means.

[0044] In this embodiment, the multiple sliding holes 42 are all located on a plane perpendicular to the axis L of the fixing member 40. This arrangement makes the force applied when the multiple support wheels 71 and the forming member 72 are pressed against the product 900 under the drive of the corresponding extruder 20 more uniform, thereby further improving the accuracy of the structural feature 910 of the product 900 formed by the forming device 100 and reducing the probability of deformation of the product 900.

[0045] In this embodiment, the forming device 100 further includes an adapter 30, which is connected to the side of the chuck body 11 facing the fixing member 40. The fixing member 40 is disposed on the adapter 30. The adapter 30 has a plurality of clearance notches 31, which correspond one-to-one with each extrusion member 20. That is, the plurality of clearance notches 31 correspond one-to-one with the plurality of extrusion members 20. Each clearance notch 31 extends from the peripheral sidewall of the adapter 30 toward the axis L of the fixing member 40. Each extrusion member 20 is movably disposed in the corresponding clearance notch 31.

[0046] By providing the adapter 30, the ease of installing the fixing component 40 is improved. By providing multiple clearance notches 31, it is easier for the claw 12 to drive the corresponding extrusion component 20 to move, and the structure of the forming device 100 is made more compact, which helps to reduce the size of the forming device 100.

[0047] In this embodiment, the adapter 30 is disc-shaped, the fixing member 40 is cylindrical, and the chuck body 11, the adapter 30, and the fixing member 40 are coaxial with axis L. Thus, when the rotary drive drives the molding device 100 to rotate, causing the molding part 72 to extrude and form the structural feature 910 of the product 900, the probability of vibration in the molding device 100 is low. This improves the accuracy of the molding device 100 in forming the structural feature 910 of the product 900 and reduces the probability of deformation of the product 900. The rotary drive can be driven by a motor.

[0048] In this embodiment, the forming device 100 further includes a first bolt 81 and a second bolt 82. The adapter 30 is mounted on the chuck body 11 via the first bolt 81, and the fixing member 40 is mounted on the adapter 30 via the second bolt 82. This facilitates the assembly and disassembly of the adapter 30 and the fixing member 40.

[0049] Please refer to the following: Figure 4 and Figure 5 In this embodiment, each extruder 20 is provided with an elongated through hole 21, the width direction of which is the same as the moving direction of the corresponding claw 12. The forming device 100 also includes a plurality of connectors 83, each connector 83 corresponding to each extruder 20, that is, each connector 83 corresponds to a plurality of extruders 20, and each connector 83 passes through the corresponding elongated through hole 21 and is connected to the corresponding claw 12.

[0050] Specifically, the connector 83 can be a connecting bolt. When the tolerance of the support wheel 71 and the forming part 72 extruding the product 900 exceeds the preset range, the position of the extruding part 20 on the corresponding jaw 12 can be adjusted by screwing the connector 83, thereby adjusting the gap between the extruding part 20 and the corresponding sliding part 51, and further adjusting the distance between the support wheel 71 and the forming part 72 and the center of the product 900, improving the concentricity of the formed structural feature 910 with the product 900 and the accuracy of the outer diameter of the structural feature 910. Thus, by setting the elongated through hole 21 and the connector 83, the convenience of adjusting the position of the extruding part 20 on the corresponding jaw 12 is improved, which is conducive to improving the accuracy of the structural feature 910 of the formed product 900.

[0051] In this embodiment, each extruder 20 has an extrusion groove 22 on the side facing the corresponding slider 51, and the slider 51 extends into the corresponding extrusion groove 22.

[0052] The extrusion groove 22 makes the structure of the molding device 100 more compact, which helps to reduce the size of the molding device 100. In addition, when the extruder 20 extrudes the corresponding sliding member 51, the extrusion groove 22 plays a certain limiting role, thereby improving the accuracy of the extruder 20 extruding the corresponding sliding member 51.

[0053] Please refer to the reference again. Figure 4 and Figure 5 In this embodiment, the slider 51 has a mounting hole 511, a limiting hole 512, and a plug-in hole 513. The mounting hole 511 extends along the sliding direction of the slider 51. The plug-in hole 513 and the limiting hole 512 are spaced apart and both communicate with the mounting hole 511. The limiting hole 512 is located between the plug-in hole 513 and the receiving hole 41. The limiting hole 512 is an oblong hole, and the width direction of the limiting hole 512 is the same as the sliding direction of the slider 51.

[0054] Each movable component 50 also includes a limiting member 53 and a stop member 54. The limiting member 53 is inserted into the limiting hole 512 and connected to the fixing member 40. The stop member 54 is inserted into the insertion hole 513. An elastic member 52 is provided in the mounting hole 513. The two ends of the elastic member 52 are connected to the stop member 54 and the limiting member 53 respectively. The elastic member 52 is connected to the sliding member 51 through the stop member 54 and to the fixing member 40 through the limiting member 53.

[0055] The mounting hole 511 facilitates the installation of the elastic element 52. The limiting element 53 and the stop element 54 facilitate the connection of the elastic element 52 to the sliding element 51 via the stop element 54, and to the fixing element 40 via the limiting element 53. Furthermore, by providing the limiting element 53 and the limiting hole 512, when the extruder 20 presses the corresponding sliding element 51 towards the receiving hole 41, the elastic element 52 is compressed. The limiting element 53 and the limiting hole 512 cooperate to limit the movement distance of the sliding element 51, thereby reducing the probability of the support wheel 71 and the molding part 72 over-pressing the product 900. This improves the accuracy of the structural features 910 of the molding product 900 and reduces the probability of deformation of the product 900.

[0056] In some other embodiments, a first storage groove (not shown) and a second storage groove (not shown) can be respectively formed on the inner wall of the sliding hole 42 and the side wall of the slider 51. The first storage groove and the second storage groove extend along the sliding direction of the slider 51, and the elastic member 52 is installed in the space formed by the first storage groove and the second storage groove. This application embodiment does not specifically limit this.

[0057] In this embodiment, the molding part 72 includes a wheel body 721 and an annular extrusion part 722. The wheel body 721 is rotatably disposed on the end of the corresponding sliding member 51 facing the receiving hole 41. The annular extrusion part 722 is sleeved on the wheel body 721 and protrudes from the peripheral sidewall of the wheel body 721. The annular extrusion part 722 is used to extrude the structural feature 910 required for the product 900.

[0058] By setting the wheel body 721 and the annular extrusion part 722, the forming part 72 can rotate around the circumference of the product 900 when extruding the structural feature 910 of the product 900, thereby making the annular extrusion part 722 uniformly extrude the circumference of the product 900 and form the structural feature 910 of the product 900, thereby improving the accuracy of the structural feature 910 of the product 900.

[0059] In this embodiment, a limiting annular groove 7211 is formed on the wheel body 721 in the circumferential direction, and the annular extrusion part 722 is sleeved in the limiting annular groove 7211. In this way, the accuracy of the annular extrusion part 722 being installed on the wheel body 721 is improved, thereby improving the accuracy of the structural feature 910 of the extruded product 900 formed by the annular extrusion part 722.

[0060] Please refer to it again. Figure 3 In this embodiment, the molding device 100 also includes a bearing 62, which is sleeved on the inner support member 61. The inner support member 61 is connected to the inner wall of the receiving hole 41 through the bearing 62.

[0061] By setting the bearing 62, the smoothness of the movement of the inner support 61 and the product 900 is improved, the friction between the inner support 61 and the inner side of the product 900 is reduced, and the probability of the product 900 rotating with the fixing part 40 is reduced, thereby improving the precision of the structural feature 910 of the extruded product 900 by the molding part 72.

[0062] In this embodiment, the inner support member 61 is fixed to the inner ring (not shown) of the bearing 62 by fastening screws (not shown) and washers (not shown), and the outer ring (not shown) of the bearing 62 is connected to the inner wall of the receiving hole 41.

[0063] In this embodiment, the end of the inner support member 61 away from the chuck body 11 has a tapered portion 611. By providing the tapered portion 611, it serves as a guide and limiter, facilitating the quick insertion of the inner support member 61 into the product 900.

[0064] In summary, the molding apparatus 100 of this application embodiment includes a clamping mechanism 10, an extruder 20, a fixing member 40, a moving component 50, an inner support member 61, multiple support wheels 71, and a molding component. When the molding apparatus 100 extrudes and molds the structural feature 910 of the product 900, the sliding member 51 abuts against the corresponding extruder 20, and the extruder 20 is movably mounted on the corresponding jaw 12. If the tolerance of the support wheels 71 and the molding component 72 when extruding the product 900 exceeds a preset range, the position of the extruder 20 on the corresponding jaw 12 can be adjusted, and the tolerance of the support wheels 71 and the molding component 72 when extruding the product 900 can be adjusted accordingly. This improves the concentricity of the structural feature 910 and the product 900, ensures that the outer diameter of the structural feature 910 is within the design range, and reduces the probability of the product 900 deforming under the extrusion action of the molding component 72. Furthermore, since the inner support member 61 is rotatably disposed in the receiving hole 41 and supports the product 900 from the inside, the probability of the support wheel 71 and the molding member 72 extruding and deforming the product 900 is reduced, and the probability of the product 900 rotating with the fixing member 40 is also reduced, thereby improving the accuracy of the structural feature 910 of the product 900 extruded and molded by the molding member 72. Thus, the molding apparatus 100 of this embodiment improves the accuracy of the structural feature 910 of the molded product 900 and reduces the probability of the product 900 deforming.

Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
