Description

Technical Field

[0001] This invention belongs to the field of forging and cleaning technology, specifically referring to a blower for flange ring forging. Background Technology

[0002] During the forging of high-temperature cast iron parts or raw materials, due to forging deformation, a cooled oxide layer will fall off the surface of the workpiece. After each workpiece is removed, the worker needs to use an air gun to blow the surface of the forging worktable to prevent these oxide layers from being placed under the next workpiece forging and affecting the forging effect.

[0003] However, large forging presses are not only dangerous to operate, but also have high temperatures near the workpieces and poor working conditions. Working in such an environment for a long time can threaten the health and even safety of workers. Therefore, there is an urgent need for a spraying equipment that can replace manual blowing and does not interfere with the original forging process. Summary of the Invention

[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a blower for flange ring forging. When the oscillating turntable rotates, it can push the long connecting rod to swing relative to the short connecting rod through the arc-shaped oscillating rod, changing the angle between the long connecting rod and the horizontal plane. As the blower head moves upward with the lifting protective cover, by reducing the angle between the long connecting rod and the horizontal plane, it can avoid the distance between the blower head and the forging table from being too far, and on the other hand, it can make the blowing area of ​​the blower head continuously expand outward, realizing the blowing of the entire table surface.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a blow molding machine for flange ring forging, including a multi-link nozzle, a swing controller, a lifting and tilting assembly, a gear ring transmission assembly, a forging base, a lifting protective cover and a gantry frame. The forging base is located below the gantry frame, the lifting protective cover is disposed on the forging base, the swing controller is rotatably disposed on the multi-link nozzle, and the multi-link nozzle is evenly distributed in a ring on the swing controller. When the lifting protective cover is raised and lowered, it can drive the swing controller to tilt and swing. The lifting and tilting assembly is located in the lifting protective cover, and the gear ring transmission assembly is located between the swing controller and the forging base. The lifting and tilting assembly and the gear ring transmission assembly will drive the swing controller to rotate when the longitudinal displacement occurs.

[0006] Furthermore, the swing control unit includes a swing turntable, a hinge seat, and an arc-shaped swing rod. The swing turntable is rotatably mounted on the lifting protective cover.

[0008] Furthermore, the lifting and tilting assembly includes a lifting platform and a mounting ring. The lifting platform is fixed to the top of the lifting protective cover, the mounting ring is fixed to the lifting platform, and the short connecting rod located inside is fixed to the mounting ring.

[0009] Preferably, the lifting and tilting assembly further includes a tilting sleeve and a tilting rod. The tilting sleeve is rotatably mounted in a bracket below the swing turntable. The bracket is fixedly connected to the gas distribution connector. The interior of the tilting sleeve is provided with spiral ridges. The tilting rod is fixedly connected to the forging base. The tilting rod is provided with a spiral groove that cooperates with the spiral ridges. The tilting sleeve rotates while lifting and lowering longitudinally.

[0010] Furthermore, the gear ring transmission assembly includes a small gear ring and a large gear ring. The small gear ring is fixed to the outside of the oscillating sleeve, and the large gear ring is fixed to the bottom of the lifting platform. The small gear ring and the large gear ring mesh and drive each other.

[0011] Furthermore, the forging base includes a base plate and a forging table. The deflecting rod is fixed to the base plate, and a column is provided on the base plate. The forging table is fixed to the column, and a central circular hole is provided in the middle of the forging table.

[0012] Furthermore, the lifting protective cover includes an air distribution connector and an electric pusher cylinder. The bottom of the electric pusher cylinder is located on the base plate, and the air distribution connector is located on the top of the electric pusher cylinder. The swing turntable is rotatably located between the lifting platform and the air distribution connector. Neither the lifting platform nor the air distribution connector can move axially relative to the swing turntable.

[0013] Preferably, the lifting protective cover further includes an outer cover and an inner cover, which are respectively fixed to the forging table and the base plate. The inner cover is engaged and slidably disposed in the outer cover, and the outer cover and the inner cover cannot rotate relative to each other.

[0014] Furthermore, the gantry frame includes a gantry support and a longitudinal forging head, wherein the longitudinal forging head is located in the middle of the gantry support and is located directly above the forging table.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: (1) During the lifting and lowering process of the protective cover, the multi-link nozzle can be moved laterally by the swing controller, so that the blowing area of ​​the nozzle can gradually expand from the inner circle to the outer circle of the forging table, thereby realizing the blowing and debris removal of the entire upper surface of the forging table.

[0016] (2) The long connecting rod and the short connecting rod form a parallelogram structure. Since the parallelogram has the characteristic that opposite sides are always parallel, the included angle between the blow nozzle and the forging table can remain unchanged when the short connecting rod on the inner side is fixed.

[0017] (3) When the swing turntable rotates, it can push the long connecting rod to swing relative to the short connecting rod through the arc swing rod, changing the angle between the long connecting rod and the horizontal plane; during the process of the blow head following the lifting protective cover to move upward, by reducing the angle between the long connecting rod and the horizontal plane, on the one hand, it can avoid the distance between the blow head and the forging table being too far, and on the other hand, it can make the blowing area of ​​the blow head continuously expand outward, so as to achieve the blowing of the entire table surface.

[0018] (4) When the oscillating sleeve rises relative to the oscillating rod, it will rotate synchronously, and then the small gear ring will drive the large gear ring to rotate, thereby achieving the technical effect of the oscillating turntable rotating while moving longitudinally.

[0019] (5) The lifting platform can be raised and lowered by electric push cylinder, and the outer and inner protective covers can prevent debris from entering it. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] like Figures 1-10 As shown, the present invention proposes a blower for flange ring forging, including a multi-link nozzle 1, a swing controller 2, a lifting and tilting assembly 3, a gear ring transmission assembly 4, a forging base 5, a lifting protective cover 6, and a gantry frame 7. The forging base 5 is located below the gantry frame 7, the lifting protective cover 6 is mounted on the forging base 5, the swing controller 2 is rotatably mounted on the multi-link nozzle 1, and the multi-link nozzle 1 is evenly distributed in a ring on the swing controller 2. When the lifting protective cover 6 is raised and lowered, it can drive the swing controller 2 to tilt and swing. The lifting and tilting assembly 3 is located in the lifting protective cover 6, and the gear ring transmission assembly 4 is located between the swing controller 2 and the forging base 5. When the lifting and tilting assembly 3 and the gear ring transmission assembly 4 are in longitudinal displacement, they will drive the swing controller 2 to rotate.

[0026] During the lifting and lowering process of the protective cover 6, the multi-link nozzle 1 can be moved laterally by the swing controller 2, so that the blowing area of ​​the nozzle 13 can gradually expand from the inner ring to the outer ring of the forging table 53, thereby realizing the blowing and debris removal of the entire upper surface of the forging table 53.

[0027] The multi-link nozzle 1 includes a long link 11, a short link 12, and a nozzle 13. The long link 11 and the short link 12 form a parallelogram structure and are hinged together. One of the short links 12 is fixed to the lifting and tilting assembly 3, and the nozzle 13 is fixed to the other short link 12. The end of the universal head 231 is located on the long link 11.

[0028] The long connecting rod 11 and the short connecting rod 12 form a parallelogram structure. Since the parallelogram has the characteristic that opposite sides are always parallel, the included angle between the blow nozzle 13 and the forging table 53 can remain unchanged when the short connecting rod 12 on the inner side is fixed.

[0029] The swing control unit 2 includes a swing turntable 21, a hinge seat 22, and an arc-shaped swing rod 23. The swing turntable 21 is rotatably mounted on the lifting protective cover 6. The hinge seat 22 is evenly distributed in a ring on the outer wall of the swing turntable 21. One end of the arc-shaped swing rod 23 is hinged to the hinge seat 22, and the other end of the arc-shaped swing rod 23 is provided with a universal joint 231.

[0030] When the oscillating turntable 21 rotates, it can push the long connecting rod 11 to swing relative to the short connecting rod 12 through the arc-shaped oscillating rod 23, changing the angle between the long connecting rod 11 and the horizontal plane. As the blow nozzle 13 moves upward with the lifting protective cover 6, by reducing the angle between the long connecting rod 11 and the horizontal plane, on the one hand, the distance between the blow nozzle 13 and the forging table 53 can be avoided from being too far, and on the other hand, the blowing area of ​​the blow nozzle 13 can be continuously expanded to achieve blowing of the entire table surface.

[0031] The lifting and tilting assembly 3 includes a lifting platform 33 and a mounting ring 34. The lifting platform 33 is fixed to the top of the lifting protective cover 6, and the mounting ring 34 is fixed to the lifting platform 33. The short connecting rod 12 located inside is fixed to the mounting ring 34.

[0032] The lifting and tilting assembly 3 also includes a tilting sleeve 31 and a tilting rod 32. The tilting sleeve 31 is rotatably mounted in a bracket below the swing turntable 21. The bracket is fixedly connected to the gas distribution connector 63. The interior of the tilting sleeve 31 is provided with a spiral ridge 311. The tilting rod 32 is fixedly connected to the forging base 5. The tilting rod 32 is provided with a spiral groove 321 that cooperates with the spiral ridge 311. The tilting sleeve 31 will also rotate while lifting and lowering longitudinally.

[0033] The gear ring transmission assembly 4 includes a small gear ring 41 and a large gear ring 42. The small gear ring 41 is fixed to the outside of the oscillating sleeve 31, and the large gear ring 42 is fixed to the bottom of the lifting platform 33. The small gear ring 41 and the large gear ring 42 mesh and transmit power.

[0034] When the oscillating sleeve 31 rises relative to the oscillating rod 32, it will rotate synchronously, and then the small gear ring 41 will drive the large gear ring 42 to rotate, thereby achieving the technical effect of the oscillating turntable 21 rotating while moving longitudinally.

[0035] The forging base 5 includes a base plate 52 and a forging table 53. The deflecting rod 32 is fixed to the base plate 52. The base plate 52 is provided with a column 521. The forging table 53 is fixed to the column 521. The forging table 53 is provided with a central circular hole 531 in the middle position.

[0036] The lifting protective cover 6 includes an air distribution connector 63 and an electric pusher cylinder 51. The bottom of the electric pusher cylinder 51 is located on the base plate 52, and the air distribution connector 63 is located on the top of the electric pusher cylinder 51. The swing turntable 21 is rotatably located between the lifting platform 33 and the air distribution connector 63. Neither the lifting platform 33 nor the air distribution connector 63 can move axially relative to the swing turntable 21.

[0037] The lifting protective cover 6 also includes an outer cover 61 and an inner cover 62. The outer cover 61 and the inner cover 62 are respectively fixed to the forging table 53 and the base plate 52. The inner cover 62 is engaged and slidably disposed in the outer cover 61. The outer cover 61 and the inner cover 62 cannot rotate relative to each other.

[0038] The lifting platform 33 can be raised and lowered by the electric push cylinder 51, and the outer protective cover 61 and inner protective cover 62 can prevent debris from entering it.

[0039] The gantry frame 7 includes a gantry support 71 and a longitudinal forging head 72. The longitudinal forging head 72 is located in the middle of the gantry support 71 and is located directly above the forging table 53.

[0040] In practical use, the user first places the workpiece to be forged on the forging table 53, and then the longitudinal displacement of the longitudinal forging head 72 is used to forge the workpiece. During the forging process, the oxide scale on the surface of the workpiece will break off and fall onto the forging table 53. Therefore, the surface of the forging table 53 needs to be blown cleaned every time the workpiece is removed.

[0041] During the forging process, the blow nozzle 13 is completely retracted below the forging table 53, so it does not affect the forging process itself.

[0042] After the workpiece is removed, the valve is opened, and compressed gas is supplied to the gas distribution connector 63 through an external air pump. The extension of the electric push cylinder 51 drives the gas distribution connector 63, the swing turntable 21 and the lifting platform 33 to rise synchronously. When the gas distribution connector 63 rises with the electric push cylinder 51, it cannot rotate under the constraint of the electric push cylinder 51, and the lifting platform 33 cannot rotate under the constraint of the outer protective cover 61 and the inner protective cover 62. As the oscillating sleeve 31 rises along with the oscillating turntable 21, it rotates within the oscillating turntable 21 through the engagement of the spiral grooves 311 and 321. Simultaneously, the oscillating sleeve 31 drives the oscillating turntable 21 to rotate through the meshing of the small gear ring 41 and the large gear ring 42.

[0043] When the oscillating turntable 21 rotates, it pushes the arc-shaped oscillating rod 23, thereby changing the angle between the long connecting rod 11 and the horizontal plane, and thus controlling the outward expansion of the nozzle 13; The long connecting rod 11 and the short connecting rod 12 form a parallelogram structure. Since the parallelogram has the characteristic that opposite sides are always parallel, the included angle between the blow nozzle 13 and the forging table 53 can remain unchanged when the short connecting rod 12 on the inner side is fixed.

[0044] Therefore, as the electric push cylinder 51 extends, the blow nozzle 13 located at the end of the long connecting rod 11 will translate in a plane, and the angle between the blow nozzle 13 and the forging table 53 remains unchanged during the translation process, and the distance between the blow nozzle 13 and the forging table 53 does not change much. The purging areas of each group of blow nozzles 13 form a ring with a certain width, and this ring continuously increases along the upper surface of the forging table 53, thereby achieving the purging and cleaning of the entire forging table 53.

[0045] After the purging is completed, simply stop the air supply and control the electric pusher cylinder 51 to retract, so that the above mechanisms can be reset synchronously until they are completely retracted below the forging table 53.

[0046] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0047] The present invention and its embodiments have been described above.
