Description

Technical Field

[0001] This application relates to the technical field of Bondi tube forming equipment, and in particular to a precision forming apparatus for heat-insulating Bondi tubes. Background Technology

[0002] The forming of Bondi tubes involves rolling the sheet metal into shape gradually using a row of rollers. Each rolling process requires the cooperation of the upper and lower rollers. The rollers in the welded pipe machine are driven by two rollers. The upper roller is connected to a power motor through a universal joint coupling, and the lower roller is also connected to a power motor through a universal joint coupling.

[0003] The existing announcement number CN206898118U, entitled "A Dual-Bearing Roll Bundy Tube Smoothing Forming Mechanism," includes a first roll and a second roll arranged in parallel. The first roll has an arc-shaped protrusion at the center of its outer circumference, and the second roll has an arc-shaped groove corresponding to the protrusion at the center of its outer circumference. The first roll has a first through hole along its axial direction, and the second roll has a second through hole along its axial direction. Bearing mounting holes are respectively provided at both ends of the first roll and both ends of the second roll, and a bearing is installed in each bearing mounting hole. A fixed shaft is installed inside each bearing. This dual-bearing roll Bundy tube smoothing forming mechanism has the advantages of scientific design, simple structure, low production cost, and high product quality.

[0004] Regarding the aforementioned technologies, the inventors discovered that when the Bondi tube is formed by twin-roll extrusion molding, the lack of vibration damping support components on the twin-bearing rolls results in a lack of buffer components for the vibration generated during the twin-roll extrusion molding of the Bondi tube, leading to a decrease in the molding accuracy of the rolled Bondi tube due to vibration. Utility Model Content

[0005] In order to overcome the problem that the existing Bondi tubes are subjected to vibration and have poor forming accuracy due to the lack of vibration damping support components on the double-bearing rollers during twin-roll extrusion molding, this application provides a heat-insulating Bondi tube precision forming device.

[0006] The precision forming device for heat-insulating Bundy tubes provided in this application adopts the following technical solution:

[0007] A precision forming device for heat-insulating Bondi tubes includes a frame, a lower coiling roller, an upper coiling roller, and a support component. The upper sides of the frame are vertically grooved, and a motor is horizontally fixed to the lower side of one end of the frame. The lower coiling roller is horizontally rotatably connected to the lower side of the frame and fixedly connected to the motor output end. Rotary plates with grooves are rotatably connected to the two ends of the upper coiling roller's shafts, and these plates are vertically slidably assembled onto the grooves of the frame. The support component includes a support frame and a bracket frame. The support frame is horizontally positioned below the frame, and bracket frames are vertically positioned on both sides of the top surface of the support frame. Sliding rods are vertically fixed on both sides of the support frame, and these rods are vertically slidably inserted into the bottom surface of the bracket frames. Lower damping rods and lower springs are vertically fixed on both sides of the top surface of the support frame, and the top ends of the lower damping rods and lower springs are fixed to the bottom surface of the bracket frames. The bracket frames are fixedly assembled to the frame using fixing screws.

[0008] By adopting the above technical solution, the motor on the starting frame drives the lower coiling roller to rotate on the frame, inserting the Bondi tube metal sheet between the lower and upper coiling rollers. The sliding plates at both ends of the upper coiling roller slide vertically down the sliding grooves on both sides of the frame, causing the upper coiling roller to press against the Bondi tube metal sheet and roll it up on the lower coiling roller. After the Bondi tube metal sheet is formed, the resulting vibration causes the support frame on the support to slide vertically on the sliding rod on the top surface of the support frame. This squeezes the lower damping rod to extend and the lower spring to deform, absorbing the vibration. The deformation potential energy of the lower spring is offset by the damping force generated by the lower damping rod, improving the stability and forming accuracy of the Bondi tube metal sheet.

[0009] Optionally, multiple connecting bolts are vertically installed through the support frame, and these connecting bolts are used to fix the assembled support frame.

[0010] By adopting the above technical solution, the support frame is fixedly installed with multiple connecting bolts to maintain the stability of the formed Bundy tube.

[0011] Optionally, a fixing plate is horizontally fixed on the top surface of the slide of the frame, and a hydraulic rod is vertically fixed on the top surface of the fixing plate.

[0012] By adopting the above technical solution, a hydraulic rod is vertically fixed on the fixed plate on the slide groove of the frame, which is used to provide pressure to push the upper rolling roller against the Bondi tube metal plate to form the lower rolling roller.

[0013] Optionally, a perforated frame is vertically fixed on the top surface of the chute plate, and a rod seat plate is vertically installed above the perforated frame. A sliding column is vertically fixed on the top surface of the rod seat plate, and a support column is vertically fixed on the bottom surface of the rod seat plate.

[0014] By adopting the above technical solution, the rod seat plate installed in the hole frame on the top of the chute plate is used to support and absorb the vertical sliding vibration of the upper rolling roller pressing against the metal sheet forming of the Bundy tube.

[0015] Optionally, the support column of the rod base plate is slidably inserted into the hole frame, and the bottom end of the support column of the rod base plate is vertically fixed with an elastic frame, and the bottom end of the elastic frame is fixed on the top surface of the slide plate.

[0016] By adopting the above technical solution, the pressure causes the support column on the rod base plate to slide into the hole frame, and the vibration causes the rod base plate to slide vertically on the hole frame. The deformation of the pressure elastic frame absorbs the pressure impact vibration.

[0017] Optionally, the output end of the hydraulic rod is horizontally fixed with an orifice plate, and the orifice plate is slidably assembled on the slide column of the rod seat plate.

[0018] By adopting the above technical solution, the orifice plate on the output end of the hydraulic rod is slidably assembled on the slide column of the rod seat plate, and when pressed, the orifice plate slides vertically on the slide column of the rod seat plate.

[0019] Optionally, an upper damping rod is vertically fixed on the top surface of the rod seat plate, and the top end of the upper damping rod is fixed on the bottom surface of the orifice plate.

[0020] By adopting the above technical solution, the vibration causes the orifice plate to slide vertically on the sliding column of the rod seat plate. The orifice plate presses against the deformation extension of the damping rod, which is used to counteract the deformation of the pressure elastic frame and absorb the pressure impact vibration.

[0021] Optionally, an upper spring is vertically fitted on the sliding column of the rod base plate, and the two ends of the upper spring are fixed to the bottom surface of the hole plate and the rod base plate, respectively.

[0022] By adopting the above technical solution, the deformation of the upper damping rod and the deformation of the upper spring are absorbed by the perforated plate, and the deformation potential energy of the upper spring is canceled by the damping force of the upper damping rod, thus ensuring the stability and accuracy of the upper rolling roll pressing the Bondi tube metal sheet for forming.

[0023] In summary, this application includes at least one of the following beneficial technical effects: During use, the motor on the starting frame drives the lower coiling roller to rotate on the frame, inserting the prepared Bundy tube metal sheet between the lower and upper coiling rollers. The sliding plates at both ends of the upper coiling roller slide vertically down the sliding grooves on both sides of the frame, driving the upper coiling roller to press against the prepared Bundy tube metal sheet and roll it up on the lower coiling roller. After the prepared Bundy tube metal sheet is formed, the resulting vibration causes the support frame on the support member to slide vertically on the sliding rod on the top surface of the support frame, squeezing the extension of the lower damping rod and the deformation of the lower spring to absorb the vibration. The deformation potential energy of the lower spring is offset by the damping force generated by the lower damping rod, thereby improving the stability and forming accuracy of the Bundy tube metal sheet.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a precision forming apparatus for heat-insulating Bundy tubes. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A precision forming device for heat-insulating Bondi tubes includes a frame 1, a lower coiling roller 2, an upper coiling roller 3, and a support member 4. The upper sides of the frame 1 are vertically provided with grooves 12, and a motor 13 is horizontally fixed to the lower side of one end of the frame 1. The lower coiling roller 2 is horizontally rotatably connected to the lower side of the frame 1, and the lower coiling roller 2 is fixedly connected to the output end of the motor 13. Slide plates 31 are rotatably connected to the rotating shafts at both ends of the upper coiling roller 3, and the slide plates 31 are vertically slidably assembled on the grooves 12 of the frame 1. The support member... 4 includes a support frame 41 and a bracket frame 44. The support frame 41 is horizontally arranged below the frame 1, and the bracket frame 44 is vertically arranged on both sides of the top surface of the support frame 41. The slide rods 43 are vertically fixed on both sides of the support frame 41, and the slide rods 43 are vertically slidably inserted into the bottom surface of the bracket frame 44. The lower damping rods 45 and lower springs 46 are vertically fixed on both sides of the top surface of the support frame 41, and the top ends of the lower damping rods 45 and lower springs 46 are fixed on the bottom surface of the bracket frame 44. The bracket frame 44 is fixedly assembled with the frame 1 by fixing screws 42.

[0032] By adopting the above technical solution, the motor 13 on the starting frame 1 drives the lower coiling roller 2 to rotate on the frame 1, inserting the prepared Bundy tube metal sheet between the lower coiling roller 2 and the upper coiling roller 3. The sliding plates 31 at both ends of the upper coiling roller 3 slide vertically down on the sliding grooves 12 on both sides of the frame 1, driving the upper coiling roller 3 to press the prepared Bundy tube metal sheet against the lower coiling roller 2 to be rolled and formed. After the prepared Bundy tube metal sheet is formed, the vibration caused the support frame 44 on the support member 4 to slide vertically on the sliding rod 43 on the top surface of the support frame 41, which squeezes the lower damping rod 45 to extend and the lower spring 46 to deform to absorb the vibration. The deformation potential energy of the lower spring 46 is offset by the damping force generated by the lower damping rod 45, which improves the stability and forming accuracy of the Bundy tube metal sheet.

[0033] Reference Figure 4 Multiple connecting bolts 11 are vertically installed through the support frame 41, and these bolts 11 are used to fix the support frame 41 in place. The support frame 41 is fixed in place by the multiple connecting bolts 11 to maintain the stability of the formed Bundy tube.

[0034] Reference Figure 5 A fixing plate 37 is horizontally fixed to the top surface of the slide groove 12 of the frame 1, and a hydraulic rod 38 is vertically fixed to the top surface of the fixing plate 37. The hydraulic rod 38, vertically fixed to the fixing plate 37 on the slide groove 12 of the frame 1, is used to provide pressure to push the upper coiling roller 3 against the Bondi tube metal sheet to form on the lower coiling roller 2. A hole frame 32 is vertically fixed to the top surface of the slide groove rotating plate 31, and a rod seat plate 33 is vertically arranged above the hole frame 32. A sliding column is vertically fixed to the top surface of the rod seat plate 33, and a support column is vertically fixed to the bottom surface of the rod seat plate 33. The rod seat plate 33 installed in the hole frame 32 on the top surface of the slide groove rotating plate 31 is used to support and absorb the vibration of the upper coiling roller 3 against the Bondi tube metal sheet during forming and slide vertically. The support column of the rod base plate 33 is slidably inserted into the hole frame 32, and a spring frame 34 is vertically fixed to the bottom end of the support column of the rod base plate 33, and the bottom end of the spring frame 34 is fixed to the top surface of the sliding plate 31. The pressure causes the support column on the rod base plate 33 to slide into the hole frame 32, and the vibration causes the rod base plate 33 to slide vertically on the hole frame 32, and the deformation of the pressure spring frame 34 absorbs the pressure impact vibration.

[0035] Reference Figure 5A perforated plate 39 is horizontally fixed to the output end of the hydraulic rod 38, and the perforated plate 39 is slidably assembled on the slide column of the rod base plate 33. When pressed, the perforated plate 39 slides vertically on the slide column of the rod base plate 33. An upper damping rod 35 is vertically fixed to the top surface of the rod base plate 33, and the top end of the upper damping rod 35 is fixed to the bottom surface of the perforated plate 39. Vibration causes the perforated plate 39 to slide vertically on the slide column of the rod base plate 33, and the perforated plate 39 deforms and extends against the upper damping rod 35 to counteract the deformation of the pressure elastic frame 34 and absorb the impact vibration. An upper spring 36 is vertically sleeved on the slide column of the rod base plate 33, and both ends of the upper spring 36 are fixed to the bottom surface of the perforated plate 39 and the rod base plate 33, respectively. The perforated plate 39 presses against the deformation extension of the upper damping rod 35 and the deformation of the upper spring 36 to absorb vibration. The deformation potential energy of the upper spring 36 is canceled by the damping force of the upper damping rod 35, ensuring the stability and precision of the upper rolling roll 3 pressing against the Bondi tube metal sheet forming.

[0036] The implementation principle of the precision forming device for heat-insulating Bundy tubes in this application embodiment is as follows: During use, the motor 13 on the starting frame 1 drives the lower coiling roller 2 to rotate on the frame 1. The metal plate for preparing the Bundy tube is inserted between the lower coiling roller 2 and the upper coiling roller 3. The sliding plates 31 at both ends of the upper coiling roller 3 slide vertically down on the sliding grooves 12 on both sides of the frame 1, causing the upper coiling roller 3 to press against the metal plate for preparing the Bundy tube and roll it up on the lower coiling roller 2. After the metal plate for preparing the Bundy tube is formed, the vibration generated causes the support frame 44 on the support member 4 to slide vertically on the sliding rod 43 on the top surface of the support frame 41. This squeezes the lower damping rod 45 to extend and the lower spring 46 to deform, absorbing the vibration. The deformation potential energy of the lower spring 46 is offset by the damping force generated by the lower damping rod 45. The hydraulic rod 38, which is vertically fixed on the fixed plate 37 fixed on the slide groove 12 of the frame 1, is used to provide pressure to push the upper coiling roller 3 against the Bondi tube metal sheet to form on the lower coiling roller 2. The rod seat plate 33 installed in the hole frame 32 on the top of the slide groove plate 31 is used to support and absorb the vibration of the upper coiling roller 3 against the Bondi tube metal sheet forming vertically. The perforated plate 39 presses against the deformation extension of the upper damping rod 35 and the deformation of the upper spring 36 to absorb the vibration. The deformation potential energy of the upper spring 36 is offset by the damping force of the upper damping rod 35, ensuring the stability and accuracy of the upper coiling roller 3 against the Bondi tube metal sheet forming.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
