Description

Technical Field

[0001] The invention belongs to the technical field of electric heating pipe processing, and in particular relates to a pipe bending mechanism for electric heating pipes. Background Art

[0002] The electric heating tube is a tubular electric heating element. It is composed of a metal tube, a spiral resistance wire, and crystallized magnesium oxide powder. Electric heating tube products are generally made of high-quality imported stainless steel tubes, imported high-temperature magnesium oxide powder, high-quality electric heating wires and other materials to make heating elements, and other structural parts are made of stainless steel. It has excellent overall performance, ultra-long life, and easy maintenance. Electric heating tubes are generally divided into two shapes, one is a straight column, and the other is a multi-bend shape. The multi-bend electric heating tube can make the heat more evenly dispersed into the air, thereby achieving a uniform heating effect. This requires the use of a special pipe bending machine to process and produce the bent electric heating tube during the production process.

[0003] However, there are some problems with the prior art: however, the bending molds and positioning molds on the pipe bending machines currently used for customized electric heating tubes on the market are all customized, resulting in the need to repeatedly disassemble and replace the positioning molds and bending molds when the pipe bending machine processes electric heating tubes of different specifications, which not only reduces the processing efficiency of the electric heating tube, but also reduces the practicality of the pipe bending machine. At the same time, when the pipe bending machine bends the electric heating tube, it is necessary to ensure that there are no impurities attached to the outer wall of the electric heating tube during the bending process, otherwise, during subsequent bending, it is easy to cause impurities to rub against the outer wall of the electric heating tube, causing damage. To ensure that there are no impurities on the outer wall of the electric heating tube on the pipe bending machine, the staff needs to wipe it repeatedly, which is time-consuming and labor-intensive, and has certain limitations. Therefore, we propose a pipe bending mechanism for electric heating tubes. Summary of the invention

Through the design of a material fixing mold and a mold replacement assembly, the material fixing mold and the pipe bending mold with the corresponding specifications of the electric heating tube can be quickly switched by rotation, thereby improving the switching efficiency of the mold, and thus effectively improving the pipe bending efficiency of the electric heating tube. At the same time, through the heat pipe cleaning assembly, it is possible to avoid bending the electric heating tube when there are many impurities on the outer wall of the electric heating tube that needs to be bent, thereby effectively improving the quality of the finished product of the electric heating tube.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 14 As shown, an embodiment of the present invention provides a pipe bending mechanism for an electric heating pipe, comprising: a pipe bending mechanism, the pipe bending mechanism is composed of a workbench 1, a rotating pipe feeding mechanism 2, a bending head 3, a material setting die 4 and a pipe bending die 12, the rotating pipe feeding mechanism 2 is arranged at one end of the upper surface of the workbench 1, the bending head 3 is movably arranged above one end of the workbench 1, and the bending head 3 is arranged correspondingly to the rotating pipe feeding mechanism 2;

[0039] like Figures 1 to 12 As shown, the rotating tube feeding mechanism 2 mentioned above is mainly used for feeding and rotating the electric heating tube, and this rotating tube feeding mechanism 2 is a mature technology of the existing tube bending machine, so the present invention will not be described in detail here.

[0040] A mold replacement assembly 10, the mold replacement assembly 10 is composed of a mold replacement component 102 and a plurality of docking components 101, a plurality of groups of bending molds 12 are provided, a plurality of groups of fixed material molds 4 are provided, and the fixed material molds 4 are arranged in pairs with the bending molds 12, and the plurality of groups of bending molds 12 are detachably arranged with the bending head 3, the bending molds 12 are arranged in pairs with the docking component 101, and the bending molds 12 are close to or away from the upper surface of the workbench 1 through the docking component 101, the fixed material mold 4 is movably connected with the docking component 101, and the plurality of groups of fixed material molds 4 are movably connected with the mold replacement component 102, and the plurality of groups of docking components 101 are arranged in an annular and equidistant manner, the mold replacement component 102 is arranged on the upper surface of the workbench 1, the plurality of groups of docking components 101 are movably connected with the mold replacement component 102, and the plurality of groups of docking components 101 are rotatably connected with the workbench 1 through the mold replacement component 102, and a first electric slide 8 is provided on the upper surface of the workbench 1, and the plurality of groups of fixed material molds 4 are detachably connected with the first electric slide 8;

[0041] It is worth noting that the above-mentioned multiple sets of bending molds 12 and multiple sets of metering molds 4 can be used for models of different specifications. Therefore, the upper surface of the workbench 1 can be replaced by a mold replacement component 10 to quickly switch the corresponding bending molds 12 and metering molds 4 according to different specifications of electric heating tubes.

[0042] like Figures 1 to 12 As shown, due to the design of the pipe bending mold 12 being close to or away from the upper surface of the workbench 1 through the docking component 101, the pipe bending mold 12 that is not connected to the bending head 3 can be raised and stored inside the docking component 101, thereby realizing effective use of space, thereby avoiding the unused pipe bending mold 12 occupying more space and affecting the normal working effect of the staff.

[0043] It is worth mentioning that, due to the design of multiple groups of docking components 101 being arranged equidistantly in a ring shape, the docking components 101 can be easily and accurately replaced with each other on the first electric slide 8, so that the positioning work for electric heating tubes of different specifications can be quickly carried out.

[0044] The heat pipe cleaning assembly 9 is arranged on the upper surface of the workbench 1 , and the heat pipe cleaning assembly 9 is arranged corresponding to the rotating pipe feeding mechanism 2 , and the multiple groups of docking components 101 are all connected to the heat pipe cleaning assembly 9 in a transmission manner.

[0045] like Figures 1 to 12 As shown, due to the design that multiple groups of docking components 101 are all transmission-connected to the heat pipe cleaning component 9, when the multiple groups of docking components 101 are rotated and switched through the mold replacement component 102, the heat pipe cleaning component 9 can be rotated to realize impurity rotation, thereby avoiding excessive accumulation of impurities in fixed positions, increasing friction with the outer wall of the electric heating tube, and causing increased costs.

[0046] Further, the docking component 101 includes a storage shell 1011, which is movably connected to the mold replacement component 102. A storage groove is provided at the bottom of the storage shell 1011, and a screw rod 1012 is rotatably connected to the upper end of the storage groove. A driving knob 1013 is fixedly installed on the upper end of the screw rod 1012. The driving knob 1013 penetrates the upper surface of the storage shell 1011. A through hole is provided on the upper surface of the storage shell 1011. A threaded shell 1014 is connected to the outer side of the screw rod 1012 through a thread. The upper end of the outer side of the threaded shell 1014 is slidably connected to the inner wall of the storage groove. A rotation groove is provided in the middle of the upper surface of the bending tube mold 12, and the lower end of the threaded shell 1014 is rotatably installed on the lower end of the rotation groove.

[0047] like Figures 1 to 9 As shown, by the design that the lower end of the threaded shell 1014 is rotatably installed on the lower end of the rotating groove, the screw rod 1012 rotates to realize the lifting and lowering action of the tube bending mold 12. Therefore, when the tube bending mold 12 is not connected to the docking plate 6, it can be lifted and stored in the storage groove, thereby preventing the tube bending mold 12 that is not connected to the docking plate 6 from being exposed to the outside for a long time. The tube bending mold 12 is likely to collide with other objects and cause damage.

[0048] Further, a bearing platform 5 is fixedly installed at one end of the workbench 1, the bending head 3 is arranged outside the bearing platform 5, and a rotating hole is opened on the upper surface of the bearing platform 5, the end of the bending head 3 is located above the inside of the rotating hole, a first pair of joints 13 is fixedly installed at the bottom of the pipe bending mold 12, a docking plate 6 is fixedly installed at the end of the bending head 3, a conical groove is opened on the upper surface of the docking plate 6, the first pair of joints 13 is arranged corresponding to the conical groove, and the first pair of joints 13 is engaged with the inside of the conical groove;

[0049] like Figures 1 to 9 As shown, through the design that the first pair of joints 13 are engaged with the inside of the conical groove, when the tube bending mold 12 corresponding to the electric heating tube is selected, the tube bending mold 12 is lowered to make the first pair of joints 13 engage with the inside of the conical groove, so that the bending head 3 and the tube bending mold 12 can be quickly connected. Therefore, there is no need to use bolts at multiple positions of the tube bending mold 12 to fix the connection with the docking plate 6, so that the tube bending molds 12 of different specifications can be replaced quickly and conveniently, thereby indirectly improving the tube bending efficiency of the electric heating tube.

[0050] It is worth mentioning that the above-mentioned pipe bending mold 12 and the docking plate 6 need to be docked and fixed because when the bending head 3 rotates around the docking plate 6, the pipe bending mold 12 and the bending head 3 rotate synchronously, which can further reduce the friction between the electric heating tube and the pipe bending mold 12, thereby effectively improving the processing quality of the electric heating tube.

[0051] Furthermore, the material fixing mold 4 is composed of a material fixing shell 401 and a material fixing plate 402. The material fixing shell 401 is movably connected to the mold replacement component 102 and the storage shell 1011 respectively. An arc groove is provided on one side of the material fixing shell 401. The material fixing plate 402 is arranged in an arc shape, and the material fixing plate 402 is slidably installed inside the arc groove. Semi-arc tooth plates 407 are fixedly installed at both ends of the material fixing plate 402. Grooves are provided at both ends of the material fixing shell 401. The ends of the two sets of grooves close to each other are provided with spring springs 406. A transmission rod 405 is fixedly installed at one end of the strip spring 406, and one end of the transmission rod 405 is rotatably installed at one end inside the groove. A reset gear 404 is fixedly installed at one end of the transmission rod 405, and the reset gear 404 is meshed and connected with a semi-arc tooth plate 407. The reset gear 404 is rotatably connected with the fixed material shell 401. Protective side plates 403 are fixedly installed at both ends of the fixed material shell 401. Protective grooves are opened on the opposite sides of the two sets of protective side plates 403, and the reset gear 404 and the semi-arc tooth plate 407 are both located inside the protective grooves.

[0052] like Figures 1 to 9 As shown, a transmission rod 405 is fixedly installed at one end of a clockwork spring 406. When the rotating tube feeding mechanism 2 drives the electric heating tube to rotate a small angle, the fixing plate 402 contacts the electric heating tube and follows it to rotate a small angle. When the electric heating tube is bent, the fixing plate 402 can automatically rotate under the action of the clockwork spring 406, thereby achieving reset, which is convenient for the subsequent positioning work of the electric heating tube.

[0053] Furthermore, the upper surface of the workbench 1 is slidably connected with a threaded slider 7 through a first electric slide 8, an arc-shaped slide groove is provided on the upper surface of the threaded slider 7, and the bottom of the fixed material shell 401 is slidably inserted into the arc-shaped slide groove; the mold replacement component 102 includes a rotating column 1022, and an installation groove is provided at one end of one side of the upper surface of the workbench 1, and a servo motor 1021 is arranged inside the installation groove, and one end of the output shaft of the servo motor 1021 is detachably connected to the rotating column 1022, and the rotating column 1022 is rotatably installed on the upper surface of the workbench 1 by the servo motor 1021, and multiple groups of fixed material shells 401 are detachably connected to the output shaft of the servo motor 1021; a second electric slide 1025 is fixedly installed on all four sides of the outer side of the rotating column 1022, and a sliding block 1026 is movably connected to one side of the second electric slide 1025, and an avoidance hole is provided on one side of the second electric slide 1025, and a docking side plate 1027 is fixedly installed on one side of the sliding block 1026 A square groove is provided on one side of the docking side plate 1027, and the sliding block 1026 is fixedly connected to the fixed material shell 401; a docking groove is provided at the bottom center of the rotating column 1022, and the output shaft of the servo motor 1021 is located inside the docking groove, and a threaded hole is provided in the middle of the upper surface of the rotating column 1022, and the threaded hole is connected to the docking groove, and a docking knob 1023 is connected to the threaded hole through a thread, and the lower end of the docking knob 1023 is rotatably connected to the lifting plate 17, and multiple groups of plug-in plates 14 are fixedly installed on the outside of the lifting plate 17, and multiple groups of avoidance grooves are provided on the outside of the rotating column 1022, and the avoidance grooves are correspondingly arranged in the avoidance holes, and the plug-in plates 14 are slidably plugged into the inside of the square groove, and a second pair of joints 16 are fixedly installed at the bottom center of the lifting plate 17, and a docking shell 1024 is fixedly installed on one end of the output shaft of the servo motor 1021, and another group of docking grooves are provided on the upper end of the docking shell 1024, and the second pair of joints 16 are slidably plugged into the inside of the other group of docking grooves.

[0054] like Figures 1 to 12 As shown, by the design that the plug-in plate 14 is slidably plugged into the inside of the square groove, when the fixing shell 401 needs to be replaced, the plug-in plate 14 is slidably plugged into the inside of the square groove to achieve mutual fixation of the threaded slider 7 and the second electric slide 1025, which can prevent the fixing shell 401 from sliding out of position when the servo motor 1021 drives the second electric slide 1025 to rotate, thereby causing the fixing shell 401 to be unable to accurately dock with the threaded slider 7. After the fixing shell 401 is docked with the threaded slider 7, the plug-in plate 14 slides upward and moves out of the square groove. The first electric slide 8 can pass through the threaded slider 7, so that the fixing shell 401 drives the fixing plate 402 to move horizontally along the axial position of the rotating tube feeding mechanism 2 to transport the electric heating tube, thereby achieving a precise positioning effect, thereby effectively improving the bending quality of the electric heating tube.

[0055] It is worth mentioning that when the second pair of connectors 16 are slidably plugged into another set of docking grooves, the servo motor 1021 can drive the rotating column 1022 to rotate through the plug-in board 14. When the second pair of connectors 16 are not slidably plugged into another set of docking grooves, the servo motor 1021 will not drive the rotating column 1022 to rotate. Therefore, it can effectively avoid the extrusion of the fixing mold 4 and the threaded slider 7 due to the staff's incorrect operation, resulting in damage, thereby improving the operating safety of the pipe bending machine.

[0056] Specifically, Figures 1 to 12 As shown, a storage assembly 11 is disposed on the upper surface of the rotating column 1022 , and a plurality of storage shells 1011 are transmission-connected to the storage assembly 11 , and the storage shells 1011 are moved close to or away from the rotating column 1022 through the storage assembly 11 .

[0057] like Figures 1 to 12 As shown, the storage assembly 11 in the above-mentioned includes a hollow rotating plate 1106, and driving tooth plates 1104 are fixedly installed on the upper surface of the hollow rotating plate 1106 all around, and the driving tooth plates 1104 are arranged in an arc shape. The upper surfaces of the multiple groups of fixed material shells 401 are provided with fixed grooves, and the inside of the fixed grooves is slidably connected with threaded sleeves 1102, and the inside of the threaded sleeves 1102 is connected with screw rods 1103 by threads. The upper surface of the fixed material shell 401 is rotatably connected with a second driven gear 1101, and the bottom center of the second driven gear 1101 is fixedly connected to the screw rod 1103, and the outer side of the driving tooth plate 1104 is meshed with the screw rod 1103. A rotating rod 21 is fixedly installed in the middle of the upper surface of the second driven gear 1101, and the upper end of the rotating rod 21 is fixedly connected. An extension rod 18 is fixedly installed, and an extension shell 19 is slidably sleeved on one end of the extension rod 18, and one end of the extension shell 19 is fixedly connected to the storage shell 1011. A bolt 20 is threadedly connected to the end of the upper surface of the extension shell 19 away from the storage shell 1011, and the bolt 20 is in contact with the upper surface of the extension rod 18, and plug-in rods 1108 are slidably connected to the outer ends of the hollow rotating plate 1106. A stabilizing ring 1105 is fixedly installed on the outer side of the rotating column 1022, and through holes are provided at both ends of the upper surface of the stabilizing ring 1105, and plug-in sleeves 1107 are symmetrically fixedly installed at both ends of the bottom of the stabilizing ring 1105, and a plug-in groove is provided on the upper surface of the plug-in groove, which is communicated with the through hole, and the lower end of the plug-in rod 1108 is slidably plugged into the plug-in groove.

[0058] Through the storage assembly 11 designed as above, when the pipe bender needs to be transported, the hollow rotating plate 1106 is rotated to rotate the angles of the multiple groups of storage shells 1011. At the same time, the sliding and contracting extension shells 19 can reduce the extension range of the multiple groups of storage shells 1011, thereby effectively reducing the space occupied by the multiple groups of storage shells 1011 and making it convenient to transport the pipe bender.

[0059] It is worth mentioning that, through the design that the lower end of the plug-in rod 1108 is slidably plugged into the inside of the plug-in slot, the plug-in rod 1108 cooperates with the plug-in sleeve 1107 to prevent the hollow rotating plate 1106 from sliding during the rotation of the rotating column 1022 by the servo motor 1021, causing the position of the storage shell 1011 to shift, thereby affecting the bending tube mold 12 at the bottom of the storage shell 1011 and being unable to accurately connect with the docking plate 6.

[0060] It should be noted that due to the design of the threaded sleeve 1102 that is slidably connected inside the fixed groove, after the second driven gear 1101 rotates to adjust the angle of the storage shell 1011, the second driven gear 1101 uses the screw 1103 to move the threaded sleeve 1102 to the lowermost end of the fixed groove, so as to prevent the second driven gear 1101 from further rotating, thereby effectively avoiding the shaking generated during the transportation of the pipe bender, which causes the multiple groups of storage shells 1011 to further rotate close to each other and collide.

[0061] Furthermore, the heat pipe cleaning assembly 9 includes a support seat 901 and a cleaning sponge 903. The support seat 901 is fixedly mounted on the upper surface of the workbench 1, and a cleaning hole is opened at one end of one side of the support seat 901. The center of the cleaning hole is arranged on the same horizontal line as the center of the rotating pipe feeding mechanism 2. The cleaning sponge 903 is filled into the cleaning hole. A transmission groove is opened inside the support seat 901, and a transmission mechanism is arranged inside the transmission groove. The cleaning sponge 903 is fixedly connected to the transmission mechanism, and the cleaning sponge 903 is rotatably arranged inside the cleaning hole through the transmission mechanism. The multiple groups of docking components 101 are all connected to the transmission mechanism in transmission; the transmission mechanism includes a bevel gear transmission mechanism 905 and a first driven gear 902, and the bevel gear transmission The mechanism 905 is arranged inside the transmission groove, the first driven gear 902 is rotatably mounted on the upper surface of the support seat 901, and the first driven gear 902 is fixedly connected to the bevel gear transmission mechanism 905, and the first driving gear 906 is fixedly mounted on the end of the bevel gear transmission mechanism 905, and the first driving gear 906 is rotatably mounted inside the transmission groove, and one side of the first driving gear 906 is meshedly connected with a rotating gear ring 904, and the rotating gear ring 904 is rotatably connected to the support seat 901, and the cleaning sponge 903 is sleeved on the outside of the rotating gear ring 904, and a transmission tooth plate 15 is fixedly mounted on the outside of the storage shell 1011, and the transmission tooth plate 15 is arranged in an arc shape, and one side of the transmission tooth plate 15 is meshedly connected with the first driven gear 902;

[0062] like Figures 1 to 12As shown, through the design that one side of the transmission tooth plate 15 is meshed and connected with the first driven gear 902, when the bending mold 12 and the fixed material mold 4 are replaced, the transmission tooth plate 15 rotates with the storage shell 1011 to mesh with the first driven gear 902, so that the first driven gear 902 cooperates with the bevel gear transmission mechanism 905, the first driving gear 906 and the rotating gear ring 904 to rotate the cleaning sponge 903, thereby changing the position where impurities are accumulated. Therefore, it is possible to effectively avoid excessive accumulation of impurities at fixed positions, resulting in friction with the electric heating tube and increasing the cost of raw materials;

[0063] It is worth mentioning that the impurities cleaned by the cleaning sponge 903 mentioned above can be docked at one end of the cleaning sponge 903, so that the impurities are accumulated at various positions on one end of the cleaning sponge 903. First, it can be convenient for the staff to quickly clean the impurities. Second, the impurities attached to one end of the cleaning sponge 903 can be shaken off through the inertia generated by the rotation, thereby reducing the speed of excessive accumulation of impurities.

[0064] Exemplarily, the bevel gear transmission mechanism 905 is implemented by two sets of bevel gears commonly seen on the market, so that when the first driven gear 902 rotates, it cooperates with the first driving gear 906 to drive the rotating gear ring 904 to rotate.

[0065] The above embodiments are only used to help understand the method and core idea of ​​the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
