Its design and manufacturing have a vital impact on the performance and life of the engine. Since the spin forming technology can accurately control the flow and deformation of materials, it can improve the strength and durability of the combustion chamber rotating parts and enhance the structural performance of the entire combustion chamber.

[0004] When the existing spinning machine is working, the spinning wheel will continuously contact the surface of the metal sheet. After working for a period of time, the spinning wheel will show a certain wear. The wear of the spinning wheel will not only increase the friction between the spinning wheel and the metal sheet, causing overheating of the metal sheet and the spinning wheel, but the spinning wheel will also cause scratches on the surface of the metal sheet, thereby increasing the scrap rate of parts and causing additional loss of metal sheets. Therefore, during the processing process, the operator is required to frequently observe and measure the wear of the guide wheel, which not only increases the operator's workload, but also there will be certain errors in the visual observation process.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 10 A spinning forming device for a combustion chamber, comprising two sets of mounting seats 20 and a workbench 11, wherein the outer surface of the mounting seat 20 is provided with a card slot 21, wherein the card slot 21 is laterally connected to a fixing frame 28 near the side of the mounting seat 20, wherein the inner surface of the fixing frame 28 is fixedly connected to a mandrel 35, wherein the outer surface of the mandrel 35 is rotatably connected to a guide wheel 33, and a lubrication component is arranged inside the fixing frame 28;

[0037] The lubrication component includes a storage cavity 29 embedded in the inner side of the fixed frame 28, the storage cavity 29 is filled with a proper amount of lubricant, the outer surface of the fixed frame 28 close to the guide wheel 33 is fixedly connected to a liquid storage cotton 31, the outer surface of the liquid storage cotton 31 is fixedly connected to a contact cotton 32, the contact cotton 32 is in rotational contact with the outer surface of the guide wheel 33, the outer surface of the liquid storage cotton 31 is fixedly connected to a cotton strip 30, the cotton strip 30 penetrates into the storage cavity 29 and is fixedly connected to the fixed frame 28.

[0038] The outer surface of the upper end of the workbench 11 is linearly slidably connected to a movable seat 16, and the outer surface of the upper end of the movable seat 16 is slidably connected to a movable seat 2 17. The outer surface of the right end of the movable seat 2 17 is fixedly connected to a support plate 18, and the outer surface of the left end of the support plate 18 is fixedly connected to a connecting rod 19. The connecting rod 19 is fixedly connected to a mounting seat 20, and an electric push rod 26 is arranged between adjacent movable seats 27.

[0039] A fixing seat 22 is fixedly connected to the right side of the outer surface of the upper end of the workbench 11, a hydraulic rod 23 is fixedly connected to the outer surface of the left end of the fixing seat 22, a contact plate 37 is fixedly connected to the output end of the hydraulic rod 23, a metal plate 36 is bonded to the outer surface of the left end of the contact plate 37, a main machine 12 is fixedly connected to the left side of the outer surface of the upper end of the workbench 11, and a motor 13 is fixedly connected to the outer surface of the left end of the main machine 12.

[0040] The right end of the output shaft of the motor 13 passes through the right side of the main machine 12 and is fixedly connected to a chuck 14. The right end of the chuck 14 is snap-connected to a fixing rod 15. The right end of the fixing rod 15 is fixedly connected to a mold 24. The outer surface of the right end of the mold 24 is in contact with the outer surface of the left end of the metal plate 36. The outer surface of the mold 24 is conical.

[0041] By adopting the above technical solution, the workbench 11 supports the main structure of the spinning machine. When the metal plate 36 is subjected to the spinning forming operation, the main machine 12 clamps and fixes the fixed rod 15 through the chuck 14, and then fixes and supports the mold 24 through the fixed rod 15, and the fixed seat 22 fixes and supports the hydraulic rod 23. When the driving end of the hydraulic rod 23 is extended, it will drive the contact plate 37 to contact the surface of the metal plate 36, and clamp the metal plate 36 with the mold 24 through the contact plate 37, and then start the motor 13 to move. The output shaft of the motor 13 drives the mold 24 to rotate synchronously through the fixed rod 15. The metal plate 36 rotates synchronously under the friction between the mold 24 and the contact plate 37. At this time, the control system of the spinning machine drives the movable seat 16 and the movable seat 2 17 through the electric push rod 26 and the drive module according to the specifications of the mold 24. The movable seat 16 and the movable seat 20 are driven to move synchronously (the electric push rod 26 and the driving module are both based on the existing technology, so their specific structure and working principle are not described in detail here), the movable seat 16 and the movable seat 2 are driven to move synchronously by the support plate 18, and the support plate 18 drives the mounting seat 20 to move through the connecting rod 19, and the card slot 21 on the surface of the mounting seat 20 can engage and support the fixed frame 28, and the fixed frame 28 supports the guide wheel 33 for rotation through the mandrel 35, so that the guide wheel 33 can rotate with the mandrel 35 as a fulcrum, and the fixed frame 28 drives the guide wheel 33 to move through the mandrel 35, and the metal plate 36 will rotate and contact with the outer surface of the guide wheel 33 during the rotation process, and the metal plate 36 is squeezed by the movement of the guide wheel 33, so that the metal plate 36 is attached to the surface of the mold 24, and the spinning manufacturing of the combustion chamber shell is completed;

[0042] The guide wheel 33 will experience certain wear during the long-term rotational contact with the metal plate 36. The wear of the guide wheel 33 will not only affect the spin-forming quality of the metal plate 36, but also shorten the service life of the guide wheel 33. For this purpose, a lubrication component is provided. The storage chamber 29 inside the fixed frame 28 is filled with a proper amount of lubricating liquid. The lubricating liquid inside the storage chamber 29 will be transferred to the liquid storage cotton 31 through the cotton strip 30, so that the liquid storage cotton 31 is filled with a proper amount of lubricating liquid, and then the lubricating liquid will be transferred to the contact cotton 32. During the rotation of the guide wheel 33, it will be in rotational contact with the contact cotton 32, and through the contact The contact cotton 32 evenly spreads the lubricating liquid on the surface of the guide wheel 33, thereby reducing the friction between the guide wheel 33 and the metal plate 36 to a certain extent, which can not only reduce the wear of the guide wheel 33 during operation and extend the service life of the guide wheel 33, but also reduce the scratches on the surface of the metal plate 36 during the spin forming process of the metal plate 36. In addition, the lubricating liquid will contact the surface of the metal plate 36 through the guide wheel 33, which can have a certain cooling effect on the metal plate 36, reduce the probability of overheating due to friction between the metal plate 36 and the guide wheel 33, and thus can effectively improve the spin forming quality of the metal plate 36.

[0043] like Figure 8 and Fig.10 As shown, an early warning component is arranged on the outside of the contact cotton 32, and the early warning component includes an arc plate 54 fixedly connected to the outer surface of the upper end of the contact cotton 32, and the arc plate 54 is located on the outside of the guide wheel 33. A sensing plate 55 is fixedly connected to the outer surface of the liquid storage cotton 31 close to the guide wheel 33, and the sensing plate 55 is electrically connected to the control system of the spinning machine. A cavity 34 is opened on the inner side of the guide wheel 33.

[0044] By adopting the above technical solution, in order to monitor the wear of the guide wheel 33 and reduce the probability of excessive wear of the guide wheel 33, an early warning component is set. The arc plate 54 on the upper side of the contact plate 37 can apply an elastic force in the direction of the guide wheel 33 to the contact cotton 32, so that the contact cotton 32 can maintain a close contact with the guide wheel 33, thereby improving the lubrication effect of the guide wheel 33 to a certain extent. When the guide wheel 33 is worn, a gap will appear between the guide wheel 33 and the contact cotton 32. At this time, the arc plate 54 will produce a gap under the action of its own elastic force. The elastic plate 43 is deformed so that the curvature of the elastic plate 43 gradually becomes smaller. When the guide wheel 33 is worn to the scrap value, the elastic plate 43 will gradually deform into a straight line. At this time, the two ends of the elastic plate 43 will contact the induction plate 55, and an electrical signal will be sent to the control system of the spinning machine through the induction plate 55 for warning, thereby reminding the operator to replace the guide wheel 33 in time, thereby reducing the risk of workpiece scrapping due to excessive wear of the guide wheel 33, without the operator having to frequently observe and measure the guide wheel 33, thereby reducing the operator's workload to a certain extent.

[0045] like Figure 5 , Figure 8 and Fig. 9 As shown, a guide assembly is provided on the outside of the fixing frame 28, and the guide assembly includes a receiving groove 38 embedded in the outer surface of the fixing frame 28, and a pin shaft 39 is fixedly connected to the inner surface of the receiving groove 38, and a swing rod 40 is rotatably connected to the outer surface of the pin shaft 39, and a movable rod 41 is fixedly connected to the end of the swing rod 40 away from the pin shaft 39, and a ball 42 is rotatably connected to the outer surface of the movable rod 41, and the outer surface of the ball 42 is in contact with the outer surface of the right end of the metal plate 36, and an elastic plate 43 is fixedly connected between the swing rod 40 and the fixing frame 28, and the elastic plate 43 is a U-shaped structure.

[0046] By adopting the above technical solution, the fixed frame 28 fixes and supports the pin shaft 39 through the storage groove 38, and rotatably supports the swing rod 40 through the pin shaft 39. The fixed frame 28 applies a certain elastic force to the swing rod 40 through the elastic plate 43, so that the swing rod 40 swings to the side away from the fixed frame 28. The swing rod 40 rotatably supports the ball 42 through the movable rod 41, and the ball 42 will fit on the surface of the metal plate 36. During the spinning process, the metal plate 36 will gradually bend under the extrusion of the guide wheel 33, and the fixed frame 28 will apply a certain pressure to the metal plate 36 through the ball 42. The rotational contact between the ball 42 and the surface of the metal plate 36 can not only keep the shape of the metal plate 36 stable and reduce the probability of reverse deformation of the metal plate 36, but also the ball 42 can share the extrusion force of the guide wheel 33, thereby slowing down the wear of the guide wheel 33 to a certain extent, and further extending the service life of the guide wheel 33.

[0047] like Figure 4 and Figure 7 As shown, a fitting component is provided on the inner side of the mold 24, and the fitting component includes a cavity 46 embedded in the inner side of the mold 24; a baffle 25 is fixedly connected to the outer surface of the upper end of the workbench 11; a sleeve 48 is fixedly connected to the outer surface of the right end of the baffle 25; the right end of the sleeve 48 is in rotational contact with the outer surface of the left end of the mold 24; a support plate 47 is fixedly connected to the outer surface of the right end of the baffle 25; and the outer surface of the upper end of the support plate 47 is fixedly connected to the sleeve 48.

[0048] The outer surface of the right end of the baffle 25 is rotatably connected to a rotating shaft 49, the outer surface of the rotating shaft 49 is fixedly connected to a friction wheel 1 50, the outer surface of the fixed rod 15 is fixedly connected to a friction wheel 2 51, the outer surface of the friction wheel 1 50 is in rotational contact with the friction wheel 2 51, the outer surface of the rotating shaft 49 is fixedly connected to a fan blade 53, the outer surface of the left end of the mold 24 is provided with slots 52, the number of the slots 52 is several groups and distributed in a ring array, and the outer surface of the mold 24 is evenly provided with mesh holes 56.

[0049] By adopting the above technical solution, when some thin plates are subjected to spinning processing, due to the small thickness of the plates, the metal plate 36 will be subjected to the centrifugal force during the rotation of the mold 24. At this time, a gap will appear between the metal plate 36 and the surface of the mold 24, thereby affecting the spinning processing accuracy. In order to increase the suction force between the metal plate 36 and the mold 24, a fitting component is provided. The workbench 11 fixedly supports the support plate 47 through the baffle 25, and fixedly supports the sleeve 48 through the support plate 47. The baffle 25 rotatably supports the rotating shaft 49. When the fixed rod 15 rotates, it will drive the friction wheel 2 51 to rotate synchronously. The friction wheel 1 50 will rotate synchronously with the friction wheel 2 51 by rotating in contact with the friction wheel 2 51. During the rotation process, the friction wheel 1 50 will The rotating shaft 49 is driven to rotate synchronously, and the fan blades 53 are driven to rotate through the rotating shaft 49. During the rotation process, the fan blades 53 will drive the air inside the sleeve 48 to be discharged from the left end of the sleeve 48. At this time, the gas inside the cavity 46 will be sucked into the sleeve 48 through the slot 52. As the amount of gas inside the cavity 46 decreases, a negative pressure will be formed inside the cavity 46. At this time, the gas outside the mold 24 will enter the cavity 46 through the mesh 56. At the same time, some of the mesh 56 will generate suction on the thin metal plate 36, so that the metal plate 36 is attached to the surface of the mold 24 under the action of suction, reducing the probability of a gap between the metal plate 36 and the mold 24 due to the centrifugal force, thereby helping to reduce processing errors and further improve the rotation processing accuracy.

[0050] like Figure 4 and Figure 6 As shown, a recovery component is arranged on the outside of the fixing frame 28, and the recovery component includes a cover body 44 fixedly connected to the upper and lower ends of the outer surface of the fixing frame 28, and the cover body 44 is distributed in an arc shape on the upper and lower sides of the guide wheel 33, and the outer surface of the lower end of the liquid storage cotton 31 is fixedly connected with a recovery cotton 45, and the lower end of the recovery cotton 45 is in contact with the inner surface of the lower cover body 44.

[0051] The number of the fixing frame 28, the guide wheel 33 and the ball 42 are two groups and are symmetrically distributed. A cavity 34 is opened inside the guide wheel 33. The outer surface of the fixing frame 28 is threaded with a bolt 27. The fixing frame 28 is connected to the mounting seat 20 through the bolt 27. The guide wheel 33 is made of wear-resistant metal material. The electric push rod 26 and the hydraulic rod 23 are electrically connected to the control system of the spinning machine.

[0052] By adopting the above technical solution, when the guide wheel 33 contacts the metal plate 36, it will rotate synchronously with the rotation of the metal plate 36. At this time, part of the lubricating fluid on the surface of the guide wheel 33 will splash outward under the action of centrifugal force, thereby causing additional loss of the lubricating fluid. For this purpose, a recovery component is provided, and two groups of covers 44 are distributed on the upper and lower sides of the guide wheel 33. At this time, the lubricating fluid splashed from the surface of the guide wheel 33 will splash onto the inner surface of the cover 44 and be collected under the guidance of the arc-shaped cover 44. The recovery cotton 45 recovers and absorbs the lubricating fluid inside the lower cover 44, thereby effectively reducing the additional loss of the lubricating fluid, and further reducing the spinning processing cost to a certain extent. The cavity 34 inside the guide wheel 33 can reduce the dead weight of the guide wheel 33 to a certain extent. The fixing frame 28 is fixedly connected to the mounting seat 20 by bolts 27, which can improve the convenience of installation of the fixing frame 28.

[0053] Usage: When spinning the combustion chamber shell, the metal plate 36 is clamped by the contact plate 37 in cooperation with the mold 24. The metal plate 36 rotates synchronously under the friction between the mold 24 and the contact plate 37. The fixed frame 28 drives the guide wheel 33 to move through the core shaft 35. The metal plate 36 will rotate and contact the outer surface of the guide wheel 33 during the rotation. The metal plate 36 is squeezed by the movement of the guide wheel 33, so that the metal plate 36 fits the surface of the mold 24. The lubricating liquid inside the storage cavity 29 is transferred to the inside of the liquid storage cotton 31 through the cotton strip 30. The guide wheel 33 will rotate and contact with the contact cotton 32 during the rotation, and the lubricating liquid is evenly applied to the surface of the guide wheel 33 through the contact cotton 32, so that it can be in a certain The friction between the guide wheel 33 and the metal plate 36 is reduced to a certain extent. The lubricating liquid splashed from the surface of the guide wheel 33 will splash onto the inner surface of the cover body 44 and be collected under the guiding action of the arc-shaped cover body 44. When the guide wheel 33 is worn to the scrap value, the two ends of the elastic plate 43 will contact the induction plate 55, and an electrical signal will be sent to the control system of the spinning machine through the induction plate 55 for warning, so as to remind the operator to replace the guide wheel 33 in time. The fixed frame 28 will apply a certain pressure to the metal plate 36 through the ball 42. The rotational contact between the ball 42 and the surface of the metal plate 36 can not only keep the shape of the metal plate 36 stable, but also reduce the probability of reverse deformation of the metal plate 36, thereby further improving the rotation processing accuracy.

[0054] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto.
